Description

[Detailed description of the invention] This invention relates to a beam and floor formwork device that can construct beams and floors together.

In conventional formwork for constructing beams and floors of reinforced concrete structures, the beam portion and floor portion are usually assembled separately. The formwork for the beam portion is complicated to assemble and dismantle, making it difficult to repurpose it. Furthermore, since the formwork for the floor portion is supported by a large number of single pipe supports, there are problems such as hindering the workability of the erected floor and creating dangers during dismantling. Therefore, a large formwork has been developed in which a beam formwork and a floor formwork are integrated and continuous on a support.

This invention also relates to a large formwork that can construct beams and floors at the same time, and is intended to provide equipment that is easier to assemble and dismantle and can be constructed more efficiently.

This invention will be explained below with reference to illustrated embodiments. In the embodiment shown in FIGS. 1 and 2, a plurality of supports 1 that can be raised and lowered at predetermined intervals are erected in parallel above the floor. There is a support beam 2 on the top of the support 1, and a metal beam form 3 with a U-shaped cross section is installed at the center of the support beam 2 via a joist 4 as necessary. Support beams 6 are installed on both sides of a certain support beam 2 via bundles 5. Note that a turnbuckle 8 used for assembly or removal is arranged between the rib 7 of the beam formwork 3 and the bundle 5.

Next, each end of a precast reinforced concrete plate 9 having a thickness corresponding to the floor thickness is placed between the opposing side walls of the beam formworks 3, 3 on the mutually adjacent shoring structures 1, slightly inside the beam formwork. If necessary, the central part of the precast reinforced concrete plate 9 is supported by a framework stage 10, and the support tensions 6, 6 on the opposing bundles 5 on the adjacent shoring 1 are supported as needed. The precast reinforced concrete plate 9 is supported by the precast reinforced concrete plate 9.

Concrete A is poured into the metal beam formwork 3 so as to be flush with the surface of the precast reinforced concrete plate 9 to construct a beam that is integrated with the floor.

This idea consists of the above-mentioned structure: the beam formwork is supported by shoring, and precast reinforced concrete plates with a thickness equivalent to the floor thickness are erected on the beam formwork and the support pullouts provided on the sides of the beam formwork. With this, it is possible to construct a beam that is integrated with the floor without using any supports or only using a framework stage in part, shortening the construction period and saving labor. Furthermore, by making the beam formwork metal, it is possible to improve the accuracy of concrete placement and to make it possible to reuse it repeatedly.
