Abstract

PURPOSE: To correctly arrange rising reinforcement in a simple procedure by using a supporting tool in which respective two U-shaped metal rods are fixed on respective sides of three L-shaped metal rods so as to direct the bent continuous projecting parts outward. CONSTITUTION: Three reinforcement supporting bodies 1 of squarely bent metal rods are arranged in parallel at a fixed pitch, and respective two connecting rods 2 of which both end parts of metal rods are U-shapedly bent are fixed on respective sides of the reinforcement supporting bodies 1 so as to direct the bent continuous projecting parts 3 outward. Synthetic resin or the like is coated on the parts 3 positioned on both end parts of the respective connecting rods 2, and the parts 3 insure covering dimensions as the contacting parts against a formwork panel 4. One-sided straight line parts of the reinforcement supporting bodies 1 of a reinforcement supporting tool formed in this way are respectively banded together with slab reinforcements 6, and the other straight line parts of the reinforcement supporting bodies 1 vertically positioned are banded together with building-up reinforcements 7 and fixed. Next, lateral reinforcements are banded and fixed together with the reinforcements 7 in the vertical direction at fixed pitches so as to assemble wall reinforcement.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support member for a standing-up reinforcing bar which is arranged to stand up from the reinforcing bar in a slab portion when forming a wall portion of a reinforced concrete structure or a rising wall of a veranda.

[0002]

2. Description of the Related Art Reinforcing bars in a wall portion of a reinforced concrete structure are formed by forming a lattice by tying up and fixing slabs to slabs laid on the floor, and tying transverse lines to the slabs. Conventionally, when arranging this stand-up bar, it is difficult to hold it vertically, and at the time of its construction, a temporary reinforcing bar support tool is arranged, and after the wall structure reinforcing bar is assembled, the support tool is removed after temporary installation. It was

[0003]

However, when arranging the conventional standing-up reinforcing bars for walls, it is necessary to pay attention not only to the verticality but also to the arrangement pitch, so that the burden on the operator is great and the assembly is completed. There was a problem that the accuracy of the reinforcing bar was difficult to obtain. The present invention has been made in view of the above points, and an object of the present invention is to provide a support tool for a standing-up reinforcing bar that allows the standing-up reinforcing bar to be accurately arranged by a simple procedure.

[0004]

In order to achieve the above-mentioned object, according to the present invention, a plurality of reinforcing bar supports bent and formed in an L shape are arranged in parallel at a predetermined pitch, and a plurality of reinforcing bar supports are provided. It is characterized in that the reinforcing bar support is integrally formed by connecting with the connecting rod.

[0005]

In the present invention, a plurality of L-shaped bent reinforcing bar supports are arranged in parallel at a predetermined pitch, and a plurality of reinforcing bar supports are connected by a plurality of connecting rods to integrally form the reinforcing bar supports. Therefore, by binding and fixing one straight line portion forming the L-shape of each of the reinforcing bar support portions arranged in parallel to the slab muscle, the other straight line portion forming the L-shape of the reinforcing bar support portion It will be located perpendicular to the horizontal plane of the slab muscle. Then, when the standing-up reinforcing bars are bound to the other linear portion positioned vertically, the standing-up reinforcing bars are arranged vertically to the slab reinforcing bars and at a predetermined pitch.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The drawings are perspective views showing an embodiment of the present invention, and FIG. 2 is a side view showing a state in which a standing reinforcing bar is fixed. The support tool for the standing-up reinforcing bar is composed of three reinforcing bar supports (1) arranged at regular intervals in the left-right direction, and four connecting rods (2) connecting the reinforcing bar supports (1) to each other. Each rebar support (1) is formed in an L-shape by bending a metal rod at a right angle.

Each connecting rod (2) is formed in a U-shape by bending both ends of a metal rod. And this connecting rod (2)
The two reinforcing bar supports (1) are fixed to the outside of the reinforcing bar support (1) in a state that the bent connecting portions face outward, so that the three reinforcing bar supports (1) are positioned in parallel at a predetermined pitch. .

Further, the folding continuous portions (3) located at both ends of each connecting rod (2) are coated with a synthetic resin or the like to form a contact portion with the form panel (4) to secure a fog size. Is done.

Next, the procedure for arranging the standing-up reinforcing bar using the reinforcing bar support thus formed will be described. One straight line portion of the reinforcing bar support (1) constituting the L-shape is bound and fixed to the slab muscle (6). Then, the reinforcing bar support (1)
The other straight line portion of is located in the vertical plane orthogonal to the horizontal plane formed by the slab muscles. Moreover, since each reinforcing bar support (1) is connected to the adjacent reinforcing bar support (1) by the connecting rod (2) and integrated, each reinforcing bar support (1) is connected to the slab reinforcement (6). Therefore, the other linear portion of the reinforcing bar support (1) is positioned perpendicular to the slab reinforcement (6).

Next, the reinforcing bar support (1) positioned vertically.
On the other straight part of the above, the standing-up reinforcing bar (7) arranged in the vertical direction of the wall is fixed by binding. Then, the horizontal reinforcing bars (8) are bundled and fixed at a constant pitch in the vertical direction between the rising reinforcing bars (7) arranged in this manner to assemble the wall reinforcing bars.

The connecting rod (2) for connecting the reinforcing bar supports (1) is formed in a U-shape, and the bent connecting portion (3) of the connecting rod (2) is in contact with the form panel (4). Because
The standing-up reinforcing bar (7) can be positioned at a certain distance from the mold surface, and the fog size of concrete can be secured securely.

FIG. 3 shows another embodiment of the present invention, which is
Each end portion of the L-shaped reinforcing bar support (1) is bent and formed inward, two L-shaped reinforcing bar supports (1) are arranged in parallel, and the pair of L-shaped reinforcing bar supports (1 ) Is connected by four connecting rods (2). The reinforcing bar support of this embodiment is used when the fog size of concrete can be secured by other means.

[0013]

As described above, according to the present invention, a plurality of reinforcing bar supports bent and formed in an L shape are arranged in parallel at a predetermined pitch, and the plurality of reinforcing bar supports are connected by a plurality of connecting rods. Since the support is integrally formed, the L-shape of the reinforcing-bar support is configured by binding and fixing one straight line part of the L-shape of the reinforcing-bar support that is arranged in parallel to each slab muscle. The other straight line portion is positioned perpendicular to the horizontal plane of the slab muscle. Then, when the standing-up reinforcing bars are bound to the other linear portion positioned vertically, the standing-up reinforcing bars are arranged vertically to the slab reinforcing bars and at a predetermined pitch. As a result, the stand-up reinforcing bar can be arranged vertically with respect to the slab bar without arranging a temporary reinforcing bar holder for holding the stand-up bar in a vertical posture, which simplifies the reinforcing bar assembly work. Therefore, it is possible to perform a highly accurate rebar assembly even for a rebar technician having low skill.
