Description

Temporary unit for building floor slab and method of construction {AN ERECTION UNIT FOR A BUILDING FLOOR SLAB AND THE ERECTION METHOD THEREOF}

Floor slabs are used to vertically divide a building's space into multiple floors according to customer requirements. Currently, the bottom floor slab of most buildings is formed of concrete as shown in FIG. 1, and the hypothesis method is a load-bearing structure (such as a concrete structure) for each floor layer or an entire building. After the load bearing structure is completed, the next top floor slab is installed. After the concrete in the lower bottom layer has been injected, it is required to wait for a period of time until the concrete has hardened sufficiently to support any weight. A support frame can then be installed on this bottom layer slab to perform another installation for the next top layer slab. However, this hypothesis still has the two disadvantages described below. That is, 1) it is necessary to wait for a period of time before the bottom layer slab is cured, and then the next top layer slab can be installed. Moreover, the support frame and the bottom layer slab mold are time consuming because each floor layer must be assembled and disassembled repeatedly after completion. 2) When the multiple bottom slabs are installed at the same time, the bottom floor slab has to support the weight of the plurality of top floor slabs, the supporting frame and the bottom layer slab mold, which adversely affects the structural strength of the floor slab, which is shown in FIG. As a result, deformation of the bottom layer slab occurs. Thus, the requirements for the structural strength of the support frame are relatively higher. In view of the conditions described above, an improved hypothesis method for building floor slabs is disclosed in SIPO Patent No. 01,129,796 (October 22, 2001) entitled "Placement Unit for Building Floor Slabs and Its Hypothesis Method". . This method is used to install a floor slab starting from the top floor of the building downwards to the bottom floor, which is generally the next step, i.e., securing the first plurality of positioning members on the load bearing structure of the building; Positioning the bottom layer slab over the first plurality of positioning members, wherein the bottom layer slab mold is supported by a support structure suspended over the first plurality of positioning members via a traction member, and then the concrete Injecting, installing a second plurality of positioning members in a position where the lower floor slab is placed after the concrete has hardened to an arbitrary degree, and suspending the support structure over the positioning members of the lower floor layer through the traction member. And secondly of the top floor slab by the aid of the towing of the towing member and under the influence of gravity Removing the plurality of positioning members of the slab mold, wherein the bottom layer slab mold is lowered to a position where the lower bottom layer slab is placed and positioned at an upper end of the positioning member, and then injecting concrete. In this hypothesis, multiple floor slabs can be installed simultaneously. Moreover, the assembly and disassembly of the bottom layer slab mold is omitted, as a result of which it is possible to accelerate the installation and to prevent the upper floor layer slab from being loaded onto the lower floor layer slab. However, this hypothesis still requires waiting a period of time until the bottom layer slab is sufficiently cured to support its deadweight, after which the bottom layer slab mold can be removed.

The present invention is intended to mitigate and / or eliminate the aforementioned drawbacks.
