Description

Background of the Invention

This invention relates to a housing structure generally having a dome-type configuration and to a method for building the same.

Brief Description of the Problem

The provision of adequate housing facilities for modern man is and has always been a perplexing and expensive problem. The costs of labor and of material prevent low-income families from obtaining adequate housing. Consequently, such families are forced to tolerate and to live in the squalor and filth of ghetto districts.

In an effort to solve the absence of satisfactory housing facilities, modern man has razed ghetto buildings whereupon low income families are forced to move on in search of new dwellings and to await the reconstruction of a sterile, impersonal, high-rise apartment complex. Unfortunately, the interim period of wait is long, unnecessary delay requiring many months before the first family can return to its remodeled district.

The bigger the high-rise apartment complex the longer its construction time and the longer a family is deprived of adequate housing. Also, there are attendant labor costs and production hours interspersed with labor difficulties which contribute to the spiraling construction costs.

There has been a long-felt need for economic and commodious housing facilities for low-income families. Such facilities must be commodious and accommodate an average-sized family. The structure and architecture of such facilities must be pleasing and have some esthetic value and inherent beauty. The structure should be sturdy and relatively easy to construct with low-cost but adequate building materials. The time required to construct such facilities should be very short such that the delay of transfering families is minimal. Each family unit should be isolated so that each family has some degree of privacy, of independence and of individuality.

In my invention described in U.S. Pat. No. 3,894,367 I have described an answer to these long-felt needs. I have described a novel dome-shaped structure which fulfills these needs and have developed a method of erecting such a structure within a greatly reduced period of time as compared to the time needed to build conventional structures. The design of my structure is flexible and it may be adapted to meet a wide range of floor space requirements and the like depending upon the various circumstances. It has a configuration which is inherently beautiful and pleasing and through inexpensive landscaping techniques it naturally blends in with the surrounding environment without intruding upon the natural beauty of the environment.

The present invention is directed to a simplification of the dome-shaped structure of my previous inventions which is easier and cheaper to produce, as well as to other desirable features.

Summary of the Invention

Generally speaking, the present invention contemplates an improvement in a dome-type structure which may be supported by a plurality of load bearing elements extending upwards from the base meeting at a common vertex. A roof deck extends over and is supported by these structural elements and vertical side panels are all disposed so as to form an enclosure. The improvement generally comprises using components for the structural elements which are generally trapezoidal and retangular in shape. The structure is assembled mostly with the interconnection of the trapezoidal and rectangular-shaped components with or, without the load bearing elements. A water trap is provided at one or more places around the base of the structure, and, in locations where there is a scarcity of water, an underground reservoir is provided beneath the structure. The arrangement provides protection against earthquakes or earth tremors. Also, a complete shell unit can be transported by air lift.

The invention as well as other objects and advantages will be better understood from the following detailed description when taken together with the accompanying drawings, in which:

Detailed Description

The Dome-Shaped Structure

In accordance with the invention, the housing structure 11 has a base 13, a plurality of support ribs 15, which support trapezoidal and substantially rectangular panels 16, assembled to form a top covering or roof 17 and a plurality of walls or side panels 19.

The base 13 is made of wood or is a concrete slab and has a substantially circular perimeter 14, and rests on the earth as a foundation, supporting the side panels 19. A wooden floor also rests on the base with support from the side panels. Concrete pilings 21 which are set in the earth support the structure. It is also possible to construct a semi-dome in which case the wood or concrete slab would have a semicircular configuration.

According to one aspect of the invention, the cross-sectional configuration of the structural elements or ribs 15 is inverted T-shaped as seen more clearly in the drawings. These structural elements or ribs 15 have a base portion 15a composed of structural steel. Base portions 15a serve to fix the ribs 15 to concrete pilings as hereafter described.

The Dome-Shaped Assembly

The housing structure 11 achieves its dome shape and strength by means of a multiplicity of trapezoidal sections which can be bolted together with out steel Ts or disposed on ribs 15. According to the first concept, T-shaped ribs are used. These ribs 15, are inverted T-shaped in cross section, the bottom of the inverted T-shape being a horizontal beam 22, the vertical portion of the inverted T-shape (steel T) also being a steel beam 22a, are first assembled in three sections, namely a lower section 15b, a center section 15c and an upper section 15d. Each section extends inwardly of the preceeding section and are joined together at joints 15e. At the top of the dome-like structure is a coupling ring 23 with a ring cover 25. Coupling ring 23 has apertures 27, and the ring cover 25 has a lower inner ring 29 which fits inside the coupling ring 23 with corresponding apertures 30. The upper rib section 15d has bolts 31 placed so as to enter the apertures 27, 30 in the coupling ring 23 and the inner ring 29. The ring cover 25, ring and rib upper section 15d are thus bolted together by nuts 33. The coupling of the lower rib section 15b to base 13 will be described later herein.

As herein before explained according to the first concept ribs 15 are of inverted T-shape, and fitted between two adjacent ribs 15, resting on one wing of each inverted T-shaped rib are trapezoidal sections. The top trapezoidal section 35 rests between two adjacent upper rib sections 15d. The second trapezoidal section 37 rests on center rib sections 15c. Resting on the lower rib section 15b is an inverted U-shaped support 39. Each trapezoidal section and support 39 consists of a frame, 41 with several ladder-like rungs 43, side panels 42 and top and bottom plexi-glass covers 45 nailed to the frame. The frames have apertures 47 and the ribs 15 have corresponding apertures 47a allowing the trapezoidal sections and the U-shaped supports to be bolted to the ribs. The inverted U-shaped support 39 has a support top 49 with legs 51. The various trapezoidal sections and the U-shaped supports with the legs are connected using foam strips 53, 53a, T-shaped couplings 55 with nuts and bolts 56. The foam strips 53, 53a are asphault impregnated that will expand and seal two sections.

According to a second embodiment, it is also possible to assemble the structure without using T-shaped ribs. The trapezoidal sections 45a and the U-shaped supports 39a have solid end walls 43a which are bolted together by nuts and bolts 56a, advantageously using shim 53a which is asphault impregnated to seal the two sections. The U-shaped supports 39a have a base 15' bolted to the legs 51a.

Anchoring the Structure

The structure contemplated herein can be supported by shop built piers 56. These can be a simple block 57 or a more solid pier 57a. This more solid arrangement uses vertical rods 59 with hook ends 61. The pier is made of concrete 63 poured in a mold reinforced with wire mesh 65 and has a steel eyelet 67 used in coupling. The pier is coupled to the rib base 15a using an air actuator 69 commercially referred to as an airstroke actuator, which has lower concrete anchor rods 71 bolted to a steel plate 73 at the base of this air actuator 69. The steel plate 73 in turn is bolted to the air actuator 69. by bolt means 75. The top of the actuator 69 is in turn bolted to the support rib base 15a by bolts 77. The steel place 73 extends out over the pier and the outer ends are supported by posts 81.

The wall side panels 19 are much easier to erect since they are bolted to the base 13 by bolts 83. In some situations, a simpler arrangement can be used to couple the rib base 15a to a concrete pier 56. The pier 56, has a central bolt 75a which passes through an aperture 75b in the rib base 15a. The bottom of rib 15 has a vertical space 75c which serves to receive the bolt 75a. A nut 75d and a washer 75e are then used to couple the rib 15 to the concrete pier 56.

The Erection of the Dome Structure

In erecting the dome structure with ribs, the lower rib 15b is coupled to the pier 57. Then, using a boat winch 85, and an erection jig 87, the second rib 15c is put into place. A frame 89 is erected to hold the roof 17 and the coupling ring 27 is removably attached to the top of the frame 89. The last rib 15d is then set in place between the center ribs 15c held by the jig 87 and the winch 85, and the coupling ring 27. In the same way, the other ribs are set in place, then the trapezoidal pieces are fitted between the ribs.

It is important to note however that the structure can be built without steel beams or ribs. With prepunched holes, nuts and bolts the structure can be easily erected by persons without building experience and can be shipped flat long distances.

The Reservoir

The dome construction described lends itself to use in areas where there is a scarcity of water and also in places which are earthquake prone, since a reservoir can be placed underneath the done-like structure. All the roof and deck rain water are directed to flow to water traps 87 disposed around the base of the structure. The reservoir 89 is round which is stronger than square shape and is disposed under the structure. Small motors 91 pump air into the water and are used to pump the water upwards, advantageously, these motors are powered by solar cells 92 and battery 96. The water flows upwards through a filter 93 to a water tap 95. Also filters are placed on all over flow lines 87a and water traps 87.

The Airborn Structure

A finished shell structure can be readily transported by air as shown in FIGS. 11a, 11b and 12. At the top of the structure is a chamber 98 into which can be fitted a helicopter 99, by removing a removable part of the roof structure, the rotor hub 101 protrudes from the roof and the main rotor 102 affixed to a drive shaft 105 which protrudes through the opening in the roof. A tail boom 106 can be affixed to the structure. The exhaust pipe 107 exits from another opening. The steering need not be in the cockpit but can be in a lower part of the structure which can have turning power or tail rotor pedals 108, driving means or cycle pitch stick 109 and lifting power, i.e, collective stick 110. The motor is in a motor hanger 111 where a fuel tank with a fuel tank vent 112 is located. The steering compartment is enclosed by a plexiglass cover 113.

It must be taken into consideration that for many years the sales of mobile homes in the United States have broken all records. The structure described makes it possible to make that kind of a move in time. For example, there is a desperate need to fly a sattelite hospital to a disaster site, or to move a field hospital to a battle site. This can now be done with the structure described.

Outline of the Structure

It is to be observed therefore that the present invention contemplates a dome-shaped building structure having a perimeter 14 which is supported by a plurality of load bearing rib assemblies 15 with a bottom plate 15a, said rib assemblies extend from the perimeter 14 up to and are fixedly secured to a locus common to these load bearing assemblies 15. The locus is horizontally within the perimeter and at a substantially vertical height above the ground. A roof deck is fixedly secured to at least a portion of the assemblies, and comprises a plurality of trapezoidal panels 35 to form a closed roof. Also supported by the rib assemblies 15 are a plurality of inverted U-shaped building 39, with side walls 42. Each of these arches 39 have one side wall 42 resting on and supported by one portion of one of the rib assemblies and the other side wall resting on and supported by a portion of another of said rib assemblies 15. At the foot of each rib assembly 15 there is a pier 57 with coupling means 69 for connecting the base of each rib assembly to the pier, which is connected to each head is a ring 27. The ribs forming these rib assemblies have an inverted T-shape in cross section. The trapezoidal panels and arches are held between two adjacent inverted T-shaped ribs. Each rib assembly has a horizontal base 15a used for connecting the rib assembly to its pier.

The pier and coupling means 69 consists of a concrete pile with vertical rods 59 having hook ends 61, said pile being reinforced with wire mesh, and with a steel eyelet 67 disposed over the pier 57. An air actuator 69 (commercially available and called an airstroke actuator) is interposed over the eyelet between the pier and rib assembly horizontal base 15a. This air actuator serves as a cushion between the structure and the pier to prevent earth tremors from acting on the structure. The main floor can be suspended and hangs from beams.

The various trapezoidal sections and the U-shaped supports wit legs are connected using foam strips 53, 53a which are asphault impregnated and will expand to seal two sections.

Each trapezoidal section and the support 39 consist of a frame 41 with side panels 42 and several ladder-like rungs 43. The top and bottom are made of plexi-glass covers nailed to the frame with nails 45a. These frames have apertures 47 and the ribs 15 have corresponding apertures 47a allowing the trapezoidal sections to be bolted to the ribs. The U-shaped supports 39 are similarly constructed.

The dome construction hereinbefore described can be placed over a reservoir with filters. The water is kept fresh by pumping fresh air into the reservoir with small motors operated by solar cells. Also, the structure can readily be transported by air and deposited in remote locations.
