Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a reinforcing bar structure for fixing wall reinforcing bars between the upper and lower parts of wall reinforcing bars of a building or for fixing the wall reinforcing bars to a column structure.

[Conventional technology]

Reinforcement bars are increasingly placed inside the shear walls of mid-to-high-rise rebars or steel-framed reinforced concrete buildings, but when it comes to anchoring this wall rebar network between the top and bottom or to column structures, so-called joint reinforcements or An interposition is often used.

Such joint reinforcements or insert reinforcements are generally straight, relatively short round bars or deformed reinforcing bars, L
Types of reinforcing bars such as U-shaped or hairpin bars have been used.

[The problem that the idea aims to solve]

However, conventional members called joint reinforcements or insert reinforcements are members that are separately attached to each vertical or horizontal reinforcement that makes up the wall reinforcing bar network, and it is difficult to prepare a large number of them. Since each bar is positioned and supported one by one on the vertical and horizontal bars of columns and wall reinforcing bars at the construction site, and then bundled and assembled, the construction process is time-consuming and there is a risk that the joint bars may shift in position due to pouring concrete, etc. and detachment.

SUMMARY OF THE INVENTION In order to eliminate the above-mentioned drawbacks, the present invention aims to provide a new reinforcing bar structure for anchoring wall bars in place of conventional joint bars.

[Means to solve the problem]

The gist of the configuration of the present invention is, as stated in the claims for utility model registration, that a pair of extension parts 1b, 1 extend parallel to each other at a predetermined distance from a bent part 1a at one end.
A plurality of joint reinforcing bar members 1, 1... having b' are arranged in parallel at intervals so that each extension part 1b, 1b... and 1b', 1b'... are aligned in parallel, and each extension part 1b , 1b . . . and 1b', 1b' .

The structure and usage of one embodiment of the present invention will be explained below.
As shown in the side view and plan view in Figure 3, the required plurality of joint reinforcing bars 1, determined by the pitch and floor height, are
1... and a total of two through reinforcing bar members 2, 2'. The joint reinforcing bar member 1 is formed by folding a straight bar with a diameter of 10 mm and a length of 1350 mm into two at the central bending part 1a so that the distance between a pair of parallel extension parts 1b and 1b' is 100 mm. The extension parts 1b and 1b' of the plurality of joint reinforcing bar members 1 are arranged in parallel at intervals of 150 mm or 200 mm so as to overlap each other vertically in FIG. 1, and are each about 220 mm from the bent part 1a. Perpendicular through-bar members 2 and 2' are welded to the distance points to form an integrated three-dimensional structure. 2a is an auxiliary reinforcing bar, but it is not essential.

This reinforcing bar structure for anchoring wall reinforcement is made by arranging a plurality of straight bars, which are the materials of the joint reinforcing bars 1, 1..., in parallel, passing them through the required locations, and welding the reinforcing bars 2, 2' and the auxiliary reinforcing bars 2a. After that, it is bent and formed at the bending part 1a.

The installation of the wall reinforcement reinforcement structure to the column structure will be explained with reference to FIGS. 4 and 5. The wall reinforcement reinforcement structure according to the present invention is erected as shown in FIG. The bent part 1a of the reinforcing bar member 1 is inserted so as to reach the inside of the reinforcing bar enclosure by the hoop bar 5 of the column structure consisting of the steel frame 3, the main bar 4, and the hoop bar 5, and the wall bar according to the present invention is fixed to the hoop bar 5. The structure is positioned on the column structure by bringing the through reinforcing bars 2 and 2' of the reinforcing bar structure into contact with each other, and the hoop reinforcement 5, the through reinforcing bars 2 and 2', and the joint reinforcing bar member 1,
The extension parts 1b, 1b'... of 1... are tied together and fixed at appropriate locations. After that, each extension part 1b, 1b'... of the joint reinforcing bar member 1 protruding from the column structure is overlapped with the two vertical bars and the tip of the horizontal bar on the side edge of the wall reinforcing bar network 6, and tied at appropriate locations. Fix it. The main reinforcing bars 4 shown inside the bent portion 1a of the joint reinforcing bar member 1 in FIG. 5 are arranged after the wall reinforcing reinforcing bar structure is inserted into the reinforcing bar enclosure of the column structure.

The reinforcing bar structure for anchoring wall reinforcements according to the present invention can also be used to join upper and lower floor wall reinforcing bar networks through pre-assembled upper beam structures. In this case, insert the tips of the vertical bars of the lower floor wall reinforcing bar network into the interior of the upper beam structure, and move the anchoring reinforcing bars without the auxiliary reinforcing bars 2a from above the upper beam structure toward the inside. Insert the reinforcing bars 2 and 2' horizontally through the body,
Place the reinforcing bars 2 and 2' through the upper beam structure or the reinforcing bars for the floor plate stretched on the upper part of the upper beam structure, and place them in contact with each other. After pouring concrete for the floor plate, the lower ends of the vertical reinforcements of the upper floor wall reinforcing bar network may be bound and joined to the bent portions 1a and extension portions 1b of the joint reinforcing bar member 1 protruding above the floor plate.

Since the reinforcing bar structure for anchoring wall reinforcements of the present invention is used as described above, it is required to have the configuration described in the scope of the utility model registration claims of the present invention. The dimensions, shape, manufacturing method, assembling method, etc. are not limited to the above-mentioned examples. For example, some of the joint reinforcing bars are made larger in diameter than others, the bent portions 1a are welded, the shape is made into a shape other than a U-shape or a U-shape, and each extension portion 1b, Various modifications, such as slightly bending a portion of 1b' and/or arranging the bent portions 1a of each reinforcing bar member 1 for joints in opposite directions, are free as long as they do not go against the gist of the present invention. be.

[Effect]

Since the reinforcing bar structure for anchoring wall reinforcing bars according to the present invention has the above-described configuration, it is easy to manufacture, and it is possible to quickly, accurately, and precisely assemble firm wall reinforcing bars. In other words, this fixing three-dimensional structure can be easily manufactured by welding only straight bars or by welding and bending. Furthermore, it can be attached to a building structure with the same speed as simultaneous positioning of multiple reinforcing bars at once, and the positioning accuracy is high. There will be no misalignment with the building structure, and some members will not fall off due to external forces such as concrete pouring.
