Description

The present invention relates to a beam-bottom frame receiver used for construction of a beam with a wall and an installation structure of the beam-bottom frame receiver.

For wall-mounted beams, after assembling the wall formwork plate on the floor, the beam bottom formwork plate and the beam side formwork plate are assembled thereon, and concrete is placed inside these wall formwork and beam formwork. Thus, the wall and the beam are integrally formed.

FIG. 3 is a view showing a support for a wall-mounted beam. As shown in FIG. 3, the support work for the beam with a wall is such that when the beam bottom mold 2 of the beam mold 1 is stood up, the beam bottom mold 2 is supported by a pipe support 3 (for example, Patent Documents). 1). In addition, the code | symbol 4 in FIG. 3 is a wall formwork, C1 is a concrete wall, C2 is a concrete beam, F is a floor surface.

However, it is necessary to adjust the beam bottom formwork in the horizontal and vertical directions. In addition, the weight of the pipe support is 10 to 15 kg, and the beam bottom mold must be supported at a pitch of about 90 to 120 cm. There was a problem that dismantling work and carrying-out work after construction would be a heavy burden on the operator.

In addition, a pipe support having a length corresponding to the height of the wall-mounted beam is required. Depending on the height of the building, diversion is impossible, and the pipe support needs to be replaced. Furthermore, in construction sites such as high-rise condominiums, there has been a problem that moving pipe supports becomes inconvenient and labor intensive.

Therefore, a first problem to be solved by the present invention is a beam bottom mold holder and a beam which can stand up a beam bottom mold without using a pipe support and can save labor for material transportation. It is to provide an installation structure of a bottom formwork holder.

The second problem to be solved by the present invention is that a beam bottom mold holder and a beam bottom mold that can be installed accurately because the installation of the beam bottom mold can be facilitated and the set-up time can be shortened. It is to provide a frame holder installation structure.

The third problem to be solved by the present invention is to provide a beam-bottom frame receiver that can safely support the beam-bottom mold and an installation structure of the beam-bottom mold receiver.

The fourth problem to be solved by the present invention is to safely install the beam form on the beam bottom mold holder by being able to stably arrange the beam bottom mold holder. It is to provide a beam bottom formwork holder and an installation structure of the beam bottom formwork holder.

As described above, the inventor of the present application has completed the installation structure of the beam-bottom frame receiver and the beam-bottom mold receiver by intensive studies in view of various problems of the conventional technology.

The invention described in claim 2
The receiver body is formed in a triangular shape by welding a steel plate horizontal member constituting the mounting portion, a steel plate vertical member arranged along the wall formwork, and a steel plate diagonal member by welding,
2. The beam-bottom mold receiver according to claim 1, wherein the receiver main body is configured to be rotatable inward by connecting a vertical member of the receiver main body to the hook portion with a hinge. It is.

The invention described in claim 3
The beam-bottom formwork holder according to claim 1 or 2 is disposed outside the wall formwork by hooking it on the top end of the wall formwork placed on the floor. A beam bottom formwork receiving structure is characterized in that a beam bottom formwork and a beam side formwork are arranged on the top.

  The beam-bottom mold receiver according to the present invention is composed of the above-described characteristic constituent elements, and has the following effects specific to the present invention according to the characteristic constituent elements. In addition, according to the installation structure of the beam bottom form frame holder configured from the above characteristic configuration requirements, the problems of the present invention can be solved sufficiently.

That is, according to the first and third devices,
“Receiver body placed outside the wall formwork for building concrete walls, a hook for hooking the top of the wall formwork to hold the receiver body, and a beam bottom provided at the upper end of the receiver body The first feature is that the beam bottom formwork can be stowed without using a pipe support, and the labor of material transportation can be saved. We were able to solve the problem.

In addition, since the beam bottom mold can be installed by hooking the beam bottom mold holder on the top end of the wall mold, it can be easily set on the wall mold. For this reason, it was possible to solve the second problem that the installation of the beam bottom formwork is facilitated, the set-up time can be shortened, and the set-up can be performed accurately.

Further, according to the second and third inventions, “the receiving body is made of a steel plate horizontal member that constitutes the mounting portion, a steel plate vertical member arranged along the wall mold, and a steel plate diagonal member. By connecting the welded parts by welding to form a triangular shape, considering the welded part as a pin joint, bending force does not act on the receiver body and the beam bottom formwork is safely supported. The third problem of being able to do so was also solved.

In addition, according to the second and third devices, the feature is that "the receiving body is configured to be rotatable inward by connecting the vertical member of the receiving body to the hook with a hinge". According to the general configuration requirements, the receiver main body can be reliably brought into contact with the outer surface of the wall mold frame without floating from the outer surface of the wall mold frame. For this reason, it solves the 4th subject that installation of a beam form on a beam bottom formwork holder can be performed safely by being able to arrange a beam bottom formwork holder stably. We were able to.
