Abstract

PURPOSE:To speed up reinforcement work by preventing vertical reinforcement bars from being tangled with a drop prevention net when placing reinforcement. CONSTITUTION:Wall reinforcement is placed in a wall structural part (b) with vertical reinforcement 1 and horizontal reinforcement 2 bridged from the wall structural part (b) to a beam structural part (a). When slab reinforcement is finished on an upper floor, virtually V-shaped hook bars 3a, which are bent so as to allow each of lower part open ends 3a to enter the beam structural part (a), are placed on the beam structural part (a) for reinforcement.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for arranging walls in a steel frame reinforced concrete construction work, and more particularly to a method for arranging rebars to be passed in the vertical direction.

[0002]

2. Description of the Related Art Conventionally, when constructing a wall in a steel-framed reinforced concrete construction work, on the concrete slab that has been cast, the reinforcement is carried out by the vertical and horizontal bars of the wall,
This wall construction point and the beam construction point where beam reinforcement is performed around the upper steel beam are covered with a formwork to form a slab formwork and arrange the slab reinforcement. After that, by pouring concrete, the wall, the beam, and the slab are integrated.

The vertical streak used in the construction of the above wall has a length projecting upward from the beam construction portion in order to ensure the integrity with the wall of the upper floor, and as shown in FIG. The bar 1 is laid out so that the tip 1a thereof projects upward through the beam construction point a. For example, as shown in FIG. Was arranged at the wall construction site b, and the worker tied it down to the lateral streak 2 below.

[0004]

By the way, since the upper end of the vertical bar of the wall is projected even after the slab concrete is placed on the upper floor, various work on the upper slab is hindered. Will come. Therefore, as shown in FIG. 7, the tip 1a of the vertical bar 1 is hooked into a hook shape, and a safety measure is taken so that an operator is not injured by the protruding vertical bar at the time of a fall or a fall. It was However,
When handling this long vertical bar, as shown in FIG. 6, its tip 1a is easily entangled with the fall prevention net c of the cross hanger on the upper floor, which makes it difficult to perform bar work effectively. There's a problem.

In view of the above circumstances, it is an object of the present invention to prevent the vertical bar from being entangled with the fall prevention net during the bar bar arranging work, and to speed up the bar bar arranging work. And

DISCLOSURE OF THE INVENTION The present invention has been made in consideration of the above-mentioned problems, and a wall reinforcement is provided at a wall construction site by arranging a vertical bar extending from the wall construction site to an upper beam construction site. After the completion of the upper floor slab reinforcement, by arranging a substantially U-shaped hook bar bent on the lower open end side so as to enter the beam construction point on the beam construction point, The problems described above are solved.

[0007]

In the present invention, the vertical streak has a length extending from the wall construction point to the upper beam construction point, and the tip of the vertical streak does not project to the upper floor. And, the hook bar arranged at the beam construction site has the part projecting above the beam construction site as the connecting part with the wall on the upper floor, and its upper end does not continuously project the reinforcing bar end upward. Like

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to an embodiment shown in FIGS. When constructing a wall, the vertical streaks 1 are provided in a length extending from the wall building location b to the upper beam building location a as shown in FIG. 1, and the upper end 1a thereof projects upward from the beam building location a. It is bent so as to wrap around the steel beam d without any problem. The vertical stirrup 1 and the horizontal stirrer 2 arrange the wall construction portion b, and since the upper end 1a of the vertical streak 1 is not bent in a hook shape, it does not get entangled with the above-mentioned fall prevention net.

After the reinforcement around the beam and the above-mentioned reinforcement of walls, the formwork of the wall, the beam and the pillar is built and the slab formwork of the upper floor is built. After the slab reinforcement is completed, the hook reinforcements 3 are inserted into the beam construction points a from above, for example, at the reinforcement arrangement pitch of the vertical reinforcements 1 and are fixedly bound (see FIG. 2). The hook streak 3 is formed in a substantially U shape with an open lower part, and is bent so that the lower open end 3a side enters the beam building portion a (see FIG. 3). The upper portions 3b of the hook streaks 3 stand side by side in a state of projecting upward from the beam construction point a and projecting even after the completion of the pouring of the slab concrete, which is a continuous portion with the wall portion on the slab (see 4).

[0010]

As described above, according to the present invention, the vertical bar extending from the wall building point to the upper beam building point is arranged in the wall building point to perform the wall reinforcing, and the upper floor slab reinforcing bar After the completion, the substantially U-shaped hook bar, which is bent so that each of the lower open end sides enters the beam building point, is arranged on the beam building point. This eliminates the entanglement with the conventional fall prevention net when handling the vertical streaks, and enables efficient work for bar arrangement work. Further, the upper part of the hook muscle is continuous in an inverted U shape, so that it is possible to prevent the worker from being stabbed when the worker falls or falls, and the work clothes are not caught. For this reason, the hooking of the upper end of the vertical streak and the attachment of the cap, which have been conventionally performed, become unnecessary, and the effect of excellent practicability is achieved.
