Heat-Insulation and Water-Proofing Brick Bond

1. Field of the Invention

The present invention relates to brick bonds, and more particularly relates to a heat-insulation and water-proofing brick bond which is easy to set up and can effectively protect against heat transmission or water permeation.

2. Description of Prior Art

In conventional roofing construction, roofing cement is polished and coverd with a layer of roofing felt or PU sheet for protection against permeation of water, and then, a brick bond or foamed concrete is set on the top to resist against heat transmission. This conventional roofing construction procedure is complicated and expensive to perform. At the same time, it gives a heavy load to the roof of a building.

The present invention is to provide a heat-insulation and water-proofing brick bond for roofing construction, which is easy and inexpensive to install and can effectively protect against heat transmission and water permeation.

The present invention is to use binding members to bind up a plurality of rectangular heat-insulation bricks which are longitudinally and latitudinally aligned. The rectangular heat-insulation bricks are each comprised of a rectangular outer shell defining therein a frog for holding an inner heat-insulation layer and sealed by an outer sealing layer. A binding member in accordance with the present invention is shaped like a channel bar, having two opposite leg portions extending from a flat top portion for fastening in corresponding grooves made on the top edge at the four sides of the rectangular heat-insulation bricks, permitting the flat top portion to fit flush with the topmost edge of the rectanglar heat-insulation bricks. Therefore, heat transmission is prohibited by the bricks, and the gap between each two heat-insulation bricks is protected by the binding members against permeation of water.

The foregoing and other objects, features and advantages of the present invention will be best understood from the following description, the appended claims and the accompanying drawings in which:

FIG. 1 is a perspective and partly sectional view of a heat-insulation brick constructed according to the present invention;

FIG. 2 illustrates an elongated, U-shaped binding member according to the present invention;

FIG. 3 is a plan view illustrating a heat-insulation and water-proofing brick bond on a roof according to the present invention; and

FIG. 4 is a sectional view taken on line A--A of FIG. 3.

Referring to FIG. 1, a heat-insulation brick in accordance with the present invention is generally comprise of outer shell 2, inner heat-insulation layer 3, and outer sealing layer 4. The outer shell 2 is made of reinforced plastics in rectangular shape, defining therein a cavity 21 for holding one or more heat-insulation layers 3 and sealed by an outer sealing layer 4. It comprises four elongated grooves 22 and four elongated projecting strips 23 at the top around the four side edges thereof, wherein the topmost edge of the elongated projecting strips 23 is slightly lower than the topmost edge of the outer shell 2. The heat-insulation layer 3 is made of high density foamed plastics, and most preferably made of high density polyrone. The outer sealing layer 4 is to seal heat-insulation layers 3 in the frog 21 of the outer shell 2. It can be made of concrete or other suitable covering materials.

During brick bonding, binding members 5 are used to tie up the bricks. As shown in FIG. 2, a binding member 5 is substantially shaped like a channel bar, having two opposite leg portions 51 and 52 extending from a flat top portion 53, wherein the leg portions 51 and 52 are respectively made in thickness approximately equal to the width of the grooves 22 and in height approximately equal to the height between the inner bottom of the grooves 22 to the topmost edge of the outer shell 2, the flat top portion 53 is made in thickness approximately equal to the level difference between the topmost edge of the outer shell 2 and the topmost edge of the projecting strips 23. Therefore, when two rows of heat-insulation bricks are arranged side by side, the binding member 5 can be fastened in position with its two leg portions 51 and 52 respectively inserted in corresponding two rows of grooves 22, top firmly secure the two rows of heat-insulation bricks together. After binding, the binding member 5 fits flush with the topmost edge of the heat-insulation bricks (see FIG. 4), and the gap between each two bricks is protected by the binding member 5 against permeation of water.

Brick bond of the present invention is processed and outlined hereinafter, with reference to FIGS. 3 and 4. Heat insulation bricks are arranged together, and longitudinally and latitudinally aligned. A plurality of binding members 5 are respectively fastened in the grooves 22 of each two longitudinal and latitudinal rows of insulation bricks to firmly bind up the bricks into a stright bond. As shown in FIG. 3, binding members 5 are continuous in the longitudinal direction and are each of brick length in the latitudinal direction. After the brick bond is formed, a water gutter 7 is made around the brick bond within the surrounding wall 6 for guiding rain water to drain through drain holes 8. In order to ensure water effect, sealing material (for example, silicon resin) is used to seal the gaps between the longitudinal and latitudinal binding members 5 or any other gaps which are not covered by the binding members 5.
