Precast concrete module which can be adapted internally to multiple uses

Abstract

A precast module built specifically with a dimension of 280118 vertical exterior walls 4 thick, horizontal walls 3 thick and a floor 4 thick. The horizontal walls are connected with attachment of rods to the vertical wall, while providing a number of openings in the horizontal and vertical walls allow access to the interior of the building unit and carrying out various plates weld in the top of the walls. The roof is constructed separately from the module, pouring concrete and is provided with through holes for locating screws and passes, and several welding plates to attach or connect to the roof and walls and have a connection to the roof and thus form an integral unit of construction.

Claims

1. A precast concrete module comprising: a horizontal slab, perimeter walls, at least one welding plate, and at least one interior wall cast as a first integral unit; a pre-stressed concrete roof and a second welding plate cast as a second integral unit separately from the first integral unit; wherein each of at least two opposing perimeter walls comprise a screw that extends vertically throughout and beyond each said at least two opposing perimeter walls; wherein each screw of said at least two opposing perimeter walls extends vertically and beyond the pre-stressed concrete roof.

2. A precast concrete module as in claim 1, wherein the pre-stressed concrete roof comprises at least a lift plate that attaches to each screw of said at least two opposing perimeter walls; wherein said at least a lift plate comprises a vertical oriented hole for module lifting.

3. A precast concrete module as in claim 1, wherein the first at least one welding plate is attached to a foundation pier.

4. A precast concrete module as in claim 1, wherein at least a perimeter wall comprises a third welding plate; and wherein the third welding plate is attached to the second at least one welding plate.

5. A precast concrete module as in claim 1, comprising holes for ventilation and plumbing pipes.

6. A precast concrete module as in claim 1, wherein the pre-stressed concrete roof contains hooks.

7. A precast concrete module as in claim 1, wherein the pre-stressed concrete roof is in a sloped position relative to the horizontal slab.

(13) To avoid confusion, the numbers shown in the illustrations are referenced in the caption above.

(14) To start building the module, the floor slab (1) is made after inserting the welding plates (9) to be used (FIG. A-1). The position of the welding plates available depends on the spatial configuration and the base. After the perimeter of vertical walls (2) with several openings are then manufactured with welding plates (9) are inserted to 18 at each end of the wall and one in the center of the wall to the roof fitting (5) and screws (7) to the lifting plate (10) (FIG. a-2). the perimeter of the horizontal wall (3) with various opening (6) is connected to the perimeter of the vertical wall (2) to bring closer (15) and welding plate (9) the same way as the vertical wall (2) (FIG. a-3) and the inner wall (4) is welded in the floor slab (1) (FIG. a-4 is also inserted).

(15) Welding the plates of the inner wall (4) (FIG. A-4) are inserted. Each inner wall has a welding plate (9) at the bottom to the floor slab (1) of low bandwidth, the top is connected to the roof (5) and on the side wall is connected adjacent (FIG. A-4). The welding plates 18 are placed side of the lower and upper edge. At the top there is a hook (8) which is inserted to allow movement of said wall in place (FIG. A-9). Once the wall welded lace, gap left for the hook (8) is filled with mortar bonding agent or another. Retaining walls that are welded in place allows for different spatial configurations and unconventional partitions.

(16) FIG. A-5, the roof (5) is constructed separately, welding plates are inserted (9) in the bottom of the roof in the same position all walls are inserted and is formed by the grid system of steel conventional reinforcement, and 5 thickness. Roof consisting of pre-stressed cables (12). These cables (12), as shown in FIG. a-5, are pre-stressed 4.500 lbs. addition of the cables (12) improves the tensile strength of the concrete shell, thereby avoiding cracks and leakage caused by the module transportation and other sources of damage. After pouring the concrete roof (5) is ready for installation, each wire (12) is cut as close as possible to the roof.

(17) The roof (5) is provided with holes for the screws (14) to pass through the roof to allow attachment to the upright walls (2) (FIG. A-5). The roof (5) also contains holes for ventilation tubes (13) to comply with existing building codes (FIG. A-5). Hooks (8) are placed one meter from each end of the side surface of the roof (5) and on each side of the center of said roof. These hooks (8) are only used for roof installation (5) a unit. Once installed, the hooks (8) are removed. Lifting plate (10) is used both for fixing the roof and elevation of the module (FIG. A-7). These lifting plates (10) are located in each screw (7) in position. As illustrated in FIG. A-10 each lifting plate (10) has two holes oriented vertical to the bolt (7) passing through, and a horizontal oriented hole (10) for lifting the module (FIG. A-7).

(18) During the roof (5) of the installation, a bonding agent (17) is applied on the upper edge of the walls as shown (FIG. A-11) to fill the gaps between said walls and roof. Once set, the excess adhesive agent (17) is removed and welded plates (9) are welded. Once the roof (5), as described above, is installed, the module is ready for desirable aesthetic appearance.

(19) Once the module is finished, it is transported to its final destination. Once at the site, is welded to the pillar of the corresponding foundation (11) (FIG. A-7 and FIG. A-8) for welding. The welding plates (9) to be placed in exact position on the surface.

(20) Caveat

(21) Although the present invention has been illustrated by a detailed description of several preferred embodiments thereof, it will be obvious to those skilled in the art that various changes in form and detail may be made therein without departing from the true scope of the invention. Therefore, the invention should be measured by its appended claims and not by the preferred embodiments above.
