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 beam.

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 the embodiments shown in FIGS. 1 and 2.

A plurality of supports 1 that can be raised and lowered are established in parallel on the floor at predetermined intervals. And this shoring 1
There is a support beam 2 at the top of the support beam 2, and in the center of the support beam 2 there is a U
A metal beam formwork 3 with a shaped cross section is installed via joists 6 if necessary. Further, bundles 5 are erected on both sides of the support beams 2 on the support 1, and support pullers 6 are installed on the bundles. 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, the left and right ends of the floor formwork 9 made of plywood or the like are erected on the opposing side walls of the metal beam formwork 3 on the mutually adjacent shoring works 1, and the respective right and left ends of the floor formwork 9 made of plywood etc. The left and right ends of the temporary beam 10 are erected between the support 6 and the support 6 on the upper opposing bundles 5, and the lower surface of the floor form 9 is supported by the temporary beam 10, and the beam form 3, Concrete A is placed on the floor formwork 9, and after the concrete hardens, shoring 1 is placed.
After removing the temporary beam 10, the beam formwork 3 and the floor formwork 9
It is designed to remove the mold.

It goes without saying that top reinforcement, truss reinforcement, etc. are placed on the floor formwork, if necessary, prior to concrete placement.

This idea consists of the above-mentioned structure, the beam formwork is supported by the shoring, the floor formwork is erected on the beam formwork and the support large pullouts provided on the sides, and between Temporary beams were erected to support the floor formwork, so
Beams and floors can be constructed at the same time without using any supports at the bottom of the floor formwork, shortening the construction period and saving labor. Furthermore, by making the beam formwork metal, it is possible to improve the accuracy of concrete pouring and to make it possible to reuse it repeatedly.
