Description

[Detailed description of the invention] "Industrial field of application" This invention relates to the provision of a large-diameter reinforcing bar receiving bracket for horizontal reinforcement on a rising part of a wall, etc.

"Prior Art" In the work of assembling reinforcing bars for large-scale construction works such as nuclear power plants, the reinforcing bars have large diameters (D22 to D51) and have a very large weight per unit length. Therefore, it is extremely difficult to manually lift the horizontal bars of a rising portion of a wall or the like and tie them to the vertical bars.

Conventionally, the following two methods are commonly used for assembling and bundling large diameter reinforcing bars.

(1) Install brackets etc. on the temporary steel frame etc.
The horizontal reinforcement is placed and tied together manually.

(2) Strive to unitize and reduce reinforcement and bundling on site as much as possible.

In addition, the horizontal reinforcing bar bracket that locks onto the vertical reinforcing bars is
This is disclosed in Publication No. 56-8722, Japanese Utility Model Application Publication No. 58-52213, etc.

``Problems that the invention attempts to solve'' However, neither of the former methods is effective in reducing the labor required for reinforcing steel work, especially for arranging large-diameter reinforcing bars. There are problems such as decreased work efficiency and increased costs. In addition, the latter method has the disadvantage that once the reinforcing bars are temporarily held and tied, they cannot be removed and become consumable items.

``Means for solving problems'' and ``effects'' This proposal was made in view of the circumstances described above, and its gist is that it is necessary to install a horizontal reinforcement support temporarily in a predetermined position, and a vertical reinforcement in the center. A bracket is integrally erected at the center of the saddle part that is assembled on the transverse reinforcement, and a post of a predetermined length is pivotally fixed to the bracket so that it can be tilted laterally.
The upper end of the column is provided with a seat having a weir wall and a floor section formed with a curved surface on the side that slopes downward toward the longitudinal reinforcement, while a longitudinal reinforcement restraint that is assembled from the side is installed in the middle of the column. The holding arm is fixedly installed, and a locking means for preventing disengagement is attached to the open side of the holding arm. By attaching the metal fittings to the vertical reinforcements and the horizontal reinforcements that have already been installed (same position as the reinforcing reinforcement position), it is possible to reduce the labor involved in tying reinforcing bars and improve work efficiency, compared to the conventional work method. The aim is to reduce costs.

"Example" This will be explained in detail below based on the example drawings.

Figures 1 a, b, c, and d are a side view, a detailed view of one component, a front view, and an arrow A-A in Figure c, showing how the receiver is assembled in use, according to an embodiment of the present invention. In the diagram, 1 and 2 are vertical reinforcements at the rising part and horizontal reinforcements that have already been tied in a predetermined position, and 3 is a horizontal reinforcement that must be placed above the horizontal reinforcement 2 at a predetermined distance. .

This product temporarily supports the horizontal reinforcement 3 in a predetermined position.A bracket 5 is integrally erected at the center of the saddle portion 4 that is assembled onto the horizontal reinforcement 2 with the vertical reinforcement 1 inside, and (The distance between the upper and lower transverse muscles) 6 is pivoted so that it can be tilted laterally. Since it is disadvantageous for the load to act on the pivot shaft as a shearing force, it is preferable for the pivot portion to be constructed of a vertically elongated loose hole a and a stop pin b as shown in the figure.

At the upper end of the support column 6, there is a floor part 8 formed with a curved surface on the side that slopes downward toward the weir wall part 7 and the longitudinal reinforcement 1 (see figure b).
A catch seat 9 is provided.

The longitudinal stripes 1 exist on the back side of the saddle surface 4 and interfere with each other, so a notch is naturally made, but there may also be a knot for the binding wire on the front side, so in order to avoid such interference, a notch 10 is provided as shown in the figure. It is advisable to make the saddle portion 4 come into close contact with the transverse muscle 2 as much as possible.

In addition, the floor portion 8 of the catch seat 9 is designed to have dimensions that can accommodate the horizontal reinforcement 3 with plenty of room, as shown in Figure a.
Further, it is preferable that the weir wall portion 7 be inclined outward to provide a guiding ability.

A restraining arm 11 that is attached to the vertical reinforcement 1 from the side is fixed in the middle of the column 6, and the arm 11
The above-mentioned assembled locking means for preventing disengagement is attached to the open side of the arm 11, and in the illustrated example, the bent base 11 of the arm 11 constituting one end of the open side is attached.
Since the L-shaped lock bar 12 is pivotally fixed to the upper horizontal part 12a, the vertical weight part 12
It is assumed that the lock is achieved by automatically assuming a position in which the opening is blocked by the action of B.

Therefore, the saddle portion 4 is placed over the horizontal reinforcement 2, and then the prop 6 in the reclined position is rotated to stand up, and the vertical reinforcement 1 is restrained by the restraining arm 11, so that the strut 6 is temporarily fixed. However, since it is not locked and stable, in the illustrated example, the vertical weight part 12b, which had been lifted to attach the restraining arm 11 to the vertical reinforcing bar 1, is released. The upper horizontal portion 12a is moved into the closed position to prevent rotation to the inverted position.

As described above, the present product temporarily supports the following horizontal reinforcement 3 by supporting the longitudinal reinforcement 1 and the horizontal reinforcement 2, which have already been reinforced and tied together.

By manufacturing the members from a strong material such as steel, even long reinforcing bars can be supported with a small number (for example, 2 to 3 points are sufficient for a 12 m bar).

In this product, when the lock is released and the longitudinal reinforcement 1 is released from the grip of the arm 11, the entire product can be rotated laterally and laid down, so that it can be easily removed after binding the horizontal reinforcement 3.

At this time, since the floor portion 8 forms a curved surface on the side, the bound transverse reinforcements 3 do not interfere with rotation.

Fig. 2 shows another embodiment of the present invention, in which Fig. A is a side view in an assembled state during use, Fig. B is a front view of the same, and Fig. C is a view taken along the line A--A in Fig. B.

In the example shown in FIG. 1, the direction of tilting and rotation is opposite to that shown in FIG. 1, and therefore the holding arm 11' is provided in the opposite direction.

Further, the seat 9' is made of a steel bar whose floor portion can be formed into a curved portion without machining.

Further, the locking means is attached to the locking pin 1 on the support column 6'.
3 is pivotally fixed, and a fitting groove 14 for the lock pin 13 is carved in the open end of the holding arm 11'.

The saddle portion 4' is constructed by welding crotch-like channels 16, 16 to the front and rear ends of a square pipe 15.

Therefore, according to the present invention, the horizontal reinforcement to be arranged at a predetermined position can be temporarily supported by simply bringing it in and placing it there.

``Effects of the invention'' Due to the structure and operation described above, this invention produces the various effects listed below.

(1) It is possible to significantly reduce the labor involved in tying large-diameter horizontal bars during reinforcing bar assembly work for large-scale construction projects.

(2) Installation can be done in an extremely short time.

(3) The structure of the mounting bracket is simple, the manufacturing cost is low, and mass production is possible.

(4) There is no need for temporary steel frames or bracket work for assembly, making it possible to significantly reduce the cost of reinforcing steel work compared to conventional methods.
