[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a beam form supporting and supporting unit that can be assembled, disassembled and moved without making small payments.

[0002]

2. Description of the Related Art Conventionally, in a beam form support used for constructing a beam member of a concrete structure, a beam form and a support supporting the beam form have been separately constructed. That is,
The construction order of the conventional beam form support is as follows.First, the support is assembled at the predetermined position to build the beam, and then the large timbers and joists are placed on it. After that, the beam side formwork was assembled.

A separator suitable for the beam width is usually used for assembling the beam side form, and a vertical end thick material or a horizontal member which is arranged outside the beam side form by connecting a foam tie and a washer to the separator. The thick timber was tightened to support the lateral pressure when placing concrete.

Further, when dismantling the formwork support work, the form ties are loosened contrary to the time of assembly, the vertical end thick material, the horizontal end thick material and the beam side formwork are paid small, and then the support work is loosened. I paid small amounts of bottom formwork, joists, and hauling materials.

Further, when diverting these form supporting members, the small paid members are moved to predetermined beam positions,
I was assembling again in the same order.

[0006]

However, the construction of such a conventional beam form supporting work requires a large number of skilled form engineers because the procedure required for assembling and disassembling it is complicated. In particular, since the separator to be attached when assembling the beam side form is carried out in a narrow space, it is very difficult for even a skilled worker to install it.

Further, since a large number of form supporting materials are assembled each time, the precision of the form is difficult to obtain.

Further, since the assembly, disassembly and movement are carried out in small payments, the types and amounts of materials to be handled become very large,
Work efficiency was poor. In addition, since a large amount of such a large amount of material is temporarily placed in the site, the site becomes complicated and there is a problem in terms of safety. In addition, since the weight of such a large amount of material is very large, it takes a great deal of effort to assemble and dismantle and raise and lower the material during movement.

In order to solve the above-mentioned drawbacks of the conventional form support, the beam form support unit according to the first aspect of the present invention has a beam side form contacted with and separated from a beam bottom form. A foldable pulling member that movably installs to form a unitized beam formwork and supports the beaming form, and a rotatable beam side formwork support member that is joined to the pulling member. , By expanding and contracting the supporting material as a unit, it is easy to assemble and disassemble the beam formwork supporting material, and it can be easily and accurately assembled without using a separator. It is intended to provide a beam form support unit. Furthermore, by unitizing the beam formwork support work, small-payment work is eliminated, work efficiency is improved, and the amount of materials temporarily placed on the site is reduced to improve site safety. Is one.

Further, in the beam form supporting member according to the second aspect of the present invention, the beam side face form supporting member includes a thick vertical member, a diagonal member, a diagonal member receiving member for receiving the diagonal member, and a diagonal member receiving portion moving means. An object of the present invention is to provide a beam form supporting unit that can support the beam side form with a simple structure and can adjust the disassembly accuracy of the beam side form with a simple operation and dismantle it. ..

Further, the beam form supporting unit according to the third aspect of the present invention is provided with a detachable moving caster attached to the support so that the form supporting unit can be integrated without paying a small amount. It is an object of the present invention to provide a beam form support work unit that can be horizontally moved as it is. Further, it is also an object to improve work efficiency and safety by diverting the formwork support work unitized in this way without making small payments.

[0012]

In order to solve the above-mentioned problems, a beam form supporting member according to a first aspect of the present invention is a beam bottom formwork having a predetermined length, and a contacting / separating and rotating operation with respect to the beam bottom formwork. A beam form made up of a beam side form having a possible predetermined length, a bending part and a beam bottom form which are arranged at a predetermined interval in the transverse direction of the beam form and can be bent in a plane in the transverse direction. A large drawing material composed of a frame supporting portion, and the beam side surface formwork is joined to the bent portion of the large drawing material to support the beam side surface formwork and the beam side surface formwork is centered around the joint portion with the large drawing material. The beam side formwork support member to be rotated, the expandable and contractible support for supporting the load acting on the large pulling member, and the beam bottom formwork support portion of the large pulling member connected to this large pulling member and the beam form It comprises a frame and a frame support member for supporting the beam side surface support member.

Further, in the beam form supporting member according to a second aspect of the present invention, the beam side face form supporting member includes a vertical end thick member rotatably attached to a bent portion of the pulling bar and an upper portion. A diagonal member that engages with a joining point with this vertical end thick member, and a lower portion engages with a diagonal member receiving member provided in a bent portion of the large hauling member, and the diagonal member receiving member along the hauling member. It is characterized in that it has a diagonal member receiving portion moving means for moving by moving.

Further, the beam form supporting work unit according to a third aspect of the present invention is characterized in that casters for moving can be attached to and detached from the supporting work.

[0015]

In the beam form supporting and supporting unit according to the present invention, a beam form unit having a predetermined length is formed by arranging the beam side form on the beam bottom form so that it can move toward and away from the beam bottom form. To do. The large drawing material that supports the beam formwork in the cross-sectional direction has a structure that can be bent in the plane of the cross-section, and is used in a straight shape when supporting the beam formwork, and is folded when dismantled. Bend. A beam side surface form supporting member for supporting the beam side surface form is joined to the bent portion of the pulling member. Since this beam side form support member can rotate the beam side form around the joint with the pulling member, the beam side form and the beam side form together with the bent part at the time of disassembly. The support member also rotates.
Further, since the support work expands during assembly to support the large drawing material and the beam formwork, but contracts during disassembly, the formwork support member supports the large drawing material, the beam formwork, the beam side formwork support member and the like.

Further, in the beam form supporting unit according to the second aspect of the invention, the angle formed between the large pulling member and the vertical end thick member is adjusted by moving the diagonal member receiving member along the large pulling member, and The thick end member and the beam side surface form are rotated about the joint with the large pulling member.

Further, in the beam form supporting member according to the third aspect, a detachable moving caster is attached to the supporting member to horizontally move the unitized beam form supporting member in a disassembled state.
