Abstract

A precast method of constructing building units comprising the steps of pouring a strip foundation monolithically with the ground floor slab, erecting full-height, pre-painted precase load-bearing wall panels with embedded dowels along the perimeter of the house; straightening the dowels and concreting the suspended slab using conventional methods; placign a precast concrete roof over the structure and installing all utilities and finishes with the use of pre-embedded and blocked out portions of the precast panels.

"DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT OF THE INVENTION:

Referring to the drawings, there is shown a multi-storey building A being constructed by the method of the present invention. Building A comprising a foundation structure F, precast bearing walls C and precast flooring D.

Shown in Figure 3 are precast bearing wall units 1 having continuous corbels 2 provided at the appropriate level elevation on the face/s wherein suspended precast slabs 3 shall be mounted. Said wall units being capable of attachment to adjacent and/or perpendicular identical units as well as the horizontal precast slabs to form a multi-storey structure S and vice versa. Attachment of said connecting members can be facilitated through mechanical attaching means. Each precast unit 1, and slab 3 is formed by the use of suitably designed moulds.

Unlike the traditional method of construction, the present invention utilizes a method of constructing a multi-storey building wherein modified strip instead of isolated footings are used, which are cast monolithically with the grade slab, along with appropriate embedded anchorage for the bearing wall panels. Once the foundation has been cast, wall panels are erected and anchored, leaving the font panel blank in order to facilitate the installation of the suspended slab/s. All panels shall have steel plates cast in them according to the drawings in order to accomplish the illustrated connections. The front panel 4 is then installed after the unit's interior has been cleared of debris. Horizontal sloping and heights of the wali panels shall be set such that the precast roof be placed in an already inclined position.

Once all the vertical panels are installed, the precast roof 5 is then lowered into position, and anchored according to Figure 10. The precast floor and roof slabs eliminate the need for formwork to be erected inside the structure to support the ;

floor slab to be mounted above, and minimizes the need for internal supporting framework. In this manner, no table formwork or internal supporting framework is required in laying the flooring. As a result, internal works in the structure can commence after the precast slab has been laid.

This process can be done repeatedly depending on the number of building levels and units being erected.

While particular embodiment of the present invention has been illustrated and described, it would be obvious to those skilled in the art that various changes and modifications can be made without departing from the spirit and scope of the invention. It is, therefore, intended to cover in the appended claims all such changes and modifications that are within the scope of the present invention.

Claims

I claim:

1. A precast method of constructing a building comprising the steps of: a) Pouring a strip foundation monolithically with the ground floor slab b) Erecting full-height, pre-painted, precast load-bearing wall panels with embedded dowels along the perimeter of the house c) Straightening the dowels and concreting the suspended slab using conventional methods d) Placing a precast concrete roof over the structure e) installing all utilities and finishes with the use of pre-embedded and blocked out portions of the precast panels

2. A precast method according to claim 1 wherein the foundation used is a monolithically-poured strip footing-and-slab system with mechanical anchorages for the precast walls as illustrated. 4, A precast method of constructing a building according to claim 1 wherein the walls transmit all the vertical loads generated by the suspended floors to the ; foundation, thereby negating the need for columns, and contain continuous miniature corbeis to support the precast slabs.

5. A precast method of constructing a building according to claims 1 and 4 wherein the roof is composed of a singular precast slab to be anchored to the j top edges of the walls using mechanical means. :
