Description

Background of the Invention

This invention relates generally to wall structures, and in particular to a decorative, non-bearing or curtain wall structure composed of a number of interfitting glass blocks. The wall structure according to the invention finds typical application in the partitions of buildings and the interior and exterior facings of enclosing walls.

Partitions have been known and used which are constructed from what is generally termed "glass brick" typically taking the form of hollow blocks of translucent glass. Since the conventional glass brick is shaped more or less like the ordinary clay brick, its laying operation requires considerable skill and attention. Moreover, the danger of collapsing is always present during the laying operation. The glass brick is also not fully satisfactory in appearance.

Summary of the Invention

It is an object of this invention to provide novel elementary glass blocks designed to be stacked in closely interfitting relationship to provide a partition, the interior or exterior facing of an enclosing wall, or like non-bearing wall structure.

Another object of the invention is to provide a wall structure in which the interfitting glass blocks can be laid even by non-professional, semiskilled labor without the possibility of collapsing.

A further object of the invention is to provide a wall structure which is highly appealing aesthetically.

With all these and other objects in view, this invention is directed, in brief, to the provision of a wall structure comprising a generally rectangular supporting frame, and a number of substantially identical glass blocks laid up within the supporting frame. Each glass block includes at least top and bottom faces that are contoured correspondingly for interfitting engagement with similar faces of the overlying and underlying blocks within the supporting frame.

The glass blocks can be either transparent or semi-transparent, colored or uncolored, as desired, to the end that the completed wall structure may be more pleasing in appearance. The blocks can be laid up with or without the use of an adhesive, and vertical bracing rods may be used as necessary for added stability.

The features which are believed to be novel and characteristic of this invention are set forth in particular in the appended claims. The invention itself, however, both as to its general organization and the functions of the various parts, together with the further objects and advantages thereof, will become apparent in the course of the following description of several specific forms of the invention, which is to be read in connection with the accompanying drawings in which like recerence characters refer to like parts throughout the several views.

Detailed Description

The wall structure according to this invention will now be described more specifically in terms of its first form illustrated in FIGS. 1 to 6. The illustrated wall structure essentially comprises a generally rectangular supporting frame 1 and a number of elementary glass blocks 2 laid up and stacked within the supporting frame in interfitting relationship.

The supporting frame 1 includes a header 3 and sill 4 at the top and bottom and side jambs 5 secured at their ends in any convenient manner to the header and sill. All these constituent members of the supporting frame 1 are U-shaped in cross section and can be made of stainless steel, aluminum, or similar material.

As will be seen from a consideration of FIG. 2, the header 3 is supported in position by longitudinally spaced pairs of steel rods 6 which are each welded or otherwise secured at one end to the header and at the other end embedded in a ceiling 7 or like overhead structure. The sill 4 is fitted over a base member 8, also of U-shaped cross section, that is anchored as by bolting 9 to a floor 10. Slotted-headed screws 11 may be used to fasten the sill 4 to the base member 8. At least one of the side jambs 5 may be fastened as by slotted-headed screws 12 (FIG. 4) to an enclosing wall 13 or the like.

FIGS. 5 and 6 best illustrate the configuration of each glass block 2. This block is solid and has a shape substantially of a right prism and is intended to be installed uprightly within the supporting frame 1. The top face of the block 2 has a rounded projecting rib 14, and its bottom face a groove 15 which is complementary to the rib 14. Furthermore, the block 2 has another rib 16 formed vertically on one of its lateral faces and a complementary groove 17 in the opposite lateral face.

As best shown in FIG. 4, the glass blocks 2 of the above described general configuration are prepared in two different lengths or heights. In one form of construction the blocks may consist of those each measuring 200 millimeters by 60 by 30 and others each measuring 250 millimeters by 60 by 30.

For assemblage, the taller and shorter glass blocks 2 may first be arranged alternately in upright disposition on the sill 4 of the supporting frame 1 from one of its side jambs 5 to the other, as illustrated in part in FIG. 4. It will be evident from FIG. 3 that the glass blocks thus arranged have their ribs 16 fitted in the grooves 17 of the adjacent blocks to make rib-and-groove joints. Additional blocks may then be laid up upon the bottom row of blocks, with the groove 15 of each additional block fitted over the rib 14 of the underlying block as illustrated in FIG. 2, until they fill the complete space bounded by the supporting frame 1. It should be noted that each of the glass blocks 2 thus stacked within the supporting frame 1 is interfitted in the rib-and-groove fashion with the upper and lower blocks and with those located on both sides.

The taller and shorter glass blocks 2 may be suitably combined in order that the blocks of each column may reach the same height just under the header 3. It is also possible, however, to sever the topmost blocks to a suitable length as required by the distance between header 3 and sill 4. A filler 18 of any suitable material such as synthetic resin may be placed in the spacing between the header 3 and the topmost blocks, as shown in FIG. 2, and a similar filler 19 between each side jamb 5 and the outermost blocks, as in FIGS. 3 and 4.

For greater stability of the wall structure the glass blocks 2 can be reinforced with one or more bracing rods 20 of steel or the like extending vertically between header 3 and sill 4, as seen in FIGS. 2, 3 and 4. Each bracing rod 20 is screw threaded at both ends which extend through the header and sill, respectively, and nuts 21 are fitted over these threaded ends of the bracing rod to securely hold same in position. Preferably, one such bracing rod 20 should be arranged every three to five columns of the blocks.

With particular reference to FIG. 3, each bracing rod 20 is intended to fit between the opposed grooves 17 of the two columns of blocks located on both sides. To this end the blocks to be arranged on either side of each bracing rod 20 may each be grooved vertically on both of the opposite lateral faces, as indicated by the numeral 22 in FIG. 3, although the blocks shown in FIGS. 5 and 6 can be used in place of such blocks 22 if their ribs 16 are directed away from the bracing rod.

The stability of the wall structure may, if necessary, be further increased by bonding all the glass blocks to each other by use of an epoxy resin adhesive, among other bonding agents. Such an adhesive may be used whenever necessary in all the succeeding forms of the invention.

To enhance the decorative aspect of the wall structure according to the invention, the glass blocks 2 may be prepared on several matching colors, and the differently colored blocks may be combined in a suitable pattern within the supporting frame. The blocks may also have their exposed faces suitably shaped unevenly, rather than exactly flat, for some extra effects. When this wall structure is used as a decorative interior or exterior facing of an enclosing wall, light sources may be installed at suitable spacings behind the glass blocks 2. This arrangement serves not only to render the blocks far more appealing aesthetically but to effect the indirect illumination of the neighboring space as well.

Another form of the invention shown in FIGS. 7 to 11 also comprises a generally rectangular supporting frame 1, and a number of interfitting glass blocks 2a laid up in horizontal disposition within the supporting frame. The supporting frame 1 can be identical to that used in the preceding form except that its sill 4a is mounted directly upon the floor 10 and anchored thereto by longitudinally spaced pairs of steel strips or rods 30, as will be evident from FIGS. 8 and 10.

As illustrated in FIG. 9, each glass block 2a is solid and substantially in the shape of a right prism like the above described block 2. Also like the preceding example the block 2a has a rib 31 formed lengthwise on its top face and a corresponding groove 32 in its bottom face. Another rib 33 and corresponding groove 34 are formed on the opposite lateral or end faces of the block 2a.

It will be observed from FIG. 8 that the blocks 2a are formed in two different lengths or horizontal dimensions. Since these blocks are designed to be laid in horizontal disposition within the supporting frame 1 as aforesaid, the longer and shorter blocks may be so used that the joint between any two horizontally adjoining blocks will not align with the joints between those located immediately over or under the two blocks.

A positioning strip 35 is fixedly mounted lengthwise on the sill 4a so as to be received in the grooves 32 of the bottom row of blocks 2a. Additional blocks are laid up on the bottom row of blocks in much the same way as ordinary bricks. As will be apparent from FIGS. 10 and 11, all the blocks 2a are interfitted in the rib-and-groove fashion. Other details of construction are identical to those previously set forth in conjunction with FIGS. 1 to 6 except that the bracing rods 20 are usually unnecessary in this second adaptation.

Glass blocks 2b shown in FIGS. 12 to 14 may be considered a modification of the blocks 2a because they are also solid and substantially in the form of a prism and are intended to be laid horizontally in use. The most pronounced feature of the modified block 2b resides in a pair of flaring fins 40 formed along the opposed marginal edges of its bottom for decorative purposes. The top face of the block 2b is shown to have a pair of parallel space ribs 41 along its longitudinal edges which can be neatly received between the flaring fins 40 of the upper block in use. Both end or lateral faces of the block 2b are contoured correspondingly or in a complementary manner in what may be termed a zigzag configuration for interengagement with similar end faces of other blocks.

The supporting frame 1 used in this third form of the invention is identical to that used in the FIGS. 1 to 6 embodiment except that its sill 4b is partly raised at 42 to provide a seating for the bottom row of blocks 2b. These blocks can be laid up in essentially the same manner as the blocks 2a, and the use of the bracing rods 20 is also unnecessary. However, caulking 43 may be applied to the gaps, if any, between the edges of the header 4 and side jambs 5 and the front and rear faces of the blocks 2b.

In still another form of the invention shown in FIGS. 15 to 19, each glass block 2c is of substantially bottle-like configuration, being hollow and necked at 50 on its top face, as best seen in FIGS. 15 and 16. The bottom face of this block has a recess 51 which is shaped and sized to fit over the neck 50 of the underlying block in use.

When seen in a plan view as in FIG. 18 or 19, the block 2c is shaped like the feathers or vanes of an arrow, such that its opposite lateral faces are correspondingly shaped into a V-shaped protuberance and indentation 52 and 53, respectively, so as to be interfittable with similar lateral faces of the adjacent blocks. Furthermore, the block 2c has a groove 54 of semicircular cross section along the ridge of its V-shaped protuberance 52 and another similar groove 55 along the ridge of its V-shaped indentation 53.

FIGS. 17 and 18 illustrate the manner of laying the glass blocks 2c within the supporting frame 1, which is exactly identical to that used in the first form of the invention. The neck 50 of each block 2c is fitted in the recess 51 of the overlying block, whereas the V-shaped protuberance 52 of each block is fitted in the corresponding indentation 53 of the block located on one side.

It will be noted from FIG. 18 that the grooves 54 of each column of blocks 2a cooperate with the opposed grooves 55 of the adjacent column of blocks to accommodate the bracing rod 20 extending vertically between the header 3 and sill 4 of the supporting frame 1. Notwithstanding the showing of FIG. 18, it is not of absolute necessity to provide the bracing rod between every two adjacent columns of blocks. This is even more so if the blocks 2c are formed in two or more different heights and so laid up that the horizontal joint between any two blocks will not align with similar joints between those located on either side.

Advantageously, the glass blocks 2c can be so laid as to provide a curved wall or partition, as illustrated in FIG. 19. It is also possible to arrange electric lamps or like light sources within these blocks.

FIGS. 20 and 21 illustrate a slight modification of the preceding adaptation, which features a glass block 2d of hollow, substantially prism-shaped configuration. This block also has a neck 60 on its top face and a corresponding recess, not shown, on its bottom face. The opposite lateral faces of the block 2d are correspondingly and complementarily shaped in a zigzag fashion for interengagement with similar lateral faces of other blocks. Grooves 61 and 62 of semicircular cross section are formed vertically on the respective lateral faces of the block 2d for accommodating the bracing rods 20 in use, as previously explained with particular reference to FIG. 18. The front and rear faces of the block 2d are corrugated or scalloped for decorative purposes. Other details of construction will be apparent from the foregoing desription of FIGS. 15 to 18.

Shown in FIGS. 22 to 24 is a further form of the invention which incorporates horizontally elongated, hollow glass blocks 2e. As best shown in FIG. 22, each block 2e has its top and bottom faces correspondingly shaped into somewhat irregular corrugations, such that in use the block is closely interfittable with other identical blocks positioned directly thereover or thereunder, as wil be apparent from FIG. 23. A neck 70 projects from one of its lateral or end faces, and a corresponding recess 71 is formed on the opposite lateral face for receiving the neck 70 of the adjacent block, as shown in FIG. 24. The front and rear faces of this block are also shown to be scalloped for decorative purposes.

The supporting frame 1 for use with the glass blocks 2e can be substantially identical to the preceding examples. Its sill 4c, however, must be grooved longitudinally to receive a support member, as designated 72 in FIG. 23, which support member has a waved upper surface to permit the bottom row of blocks 2e to rest evenly thereon. These blocks can also be formed in two or more different lengths or horizontal dimensions and can be laid up within the supporting frame 1 without aid of bracing rods.

The wall structure shown in FIGS. 25 to 30 differs from all of the preceding forms of the invention in that its glass blocks 2f are specifically designed for combined use with pairs of bracing rods 20a which are to be positioned on both sides of the respective columns of the blocks. The supporting frame 1 of this wall structure can be identical to that used, for example, in the first form of the invention except that its side jambs 5a each take the shape of a hollow rectangle in cross section, as shown in FIG. 26, and that its header 3a has its bottom closed, as shown in FIG. 27.

AS will be seen from FIGS. 25 and 26, each pair of bracing rods 20a extending vertically between the header 3a and sill 4 of the supporting frame 1 has a constant spacing therebetween to accommodate a single column of the blocks 2f in a manner still to be described. No spacing exists between the respective pairs of bracing rods; that is, one of each paired bracing rods is arranged in close contact with the opposite one of the next pair. The two outermost bracing rods are individually arranged in close contact with the respective side jambs 5a.

It will be noted from FIG. 27 that one of each paired bracing rods 20a has a removable top end portion 80. Each removable top end portion 80 has a pin 81 slidable into and out of an axial hollow interior 82 formed in the remainder of the corresponding bracing rod 20a. The length of this removable top end portion should be at least equal to the height of each block 2f.

With particular reference to FIG. 28, each glass block 2f is of bottle-like configuration, hollow, elliptical in horizontal section, and necked at 83 on its top face. The bottom face of this block has a recess 84 (FIG. 30) that is shaped and sized to fit over the neck 83 of the underlying block in use. The block 2f also has a pair of oppositely located, vertical grooves 85 for engaging the respective paired bracing rods 20a, as hereinafter explained.

For laying the glass blocks 2f within the supporting frame 1, the removable top end portion 80 of, for example, the outermost bracing rod 20a may first be raised in a manner which will be apparent from a consideration of FIG. 27. The blocks 2f can then be successively slid down between this outermost bracing rod and the adjacent rod through the widened spacing that has been formed by raising the top end portion 80. The pair of bracing rods are of course engaged in the respective grooves 85 of the successive blocks, as shown in FIG. 29, and the neck 83 of each block is fitted in the recess 84 of the overlying block, as shown in FIG. 30. After the topmost block has been laid, the top end portion 80 may be re-installed in position by having its pin 81 inserted into the axial hollow 82 of the outermost bracing rod.

The foregoing procedure is repeated to form successive columns of the blocks 2f within the supporting frame 1. The blocks 2f can also be formed in two or more different heights, and the different sized blocks can be stacked in any combinations calculated to make the wall structure more pleasing in appearance. These blocks are also suitable for housing electric lamps or the like. The use of an adhesive is usually unnecessary in this particular form.

It is believed that the various objects of this invention, either expressly stated or otherwise, have been fully accomplished in the various forms of the wall structure shown and described hereinbefore. It is also understood, however, that the invention itself is not to be restricted by the exact showing of the drawings or the description thereof but is inclusive of many modifications or changes.
