[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spacing member with a drain, and more particularly, to a spacing member with a drain in which a spacing member for a reinforcing bar and a drain member are formed by one member.

[0002]

2. Description of the Related Art In a conventional reinforced concrete building (referred to as RC building), (a) a horizontal reinforcing bar is provided at a portion of an outer wall above an opening of a building, such as an entrance or a window, with a vertical space therebetween. Vertical bars with horizontal spacing, bind the vertical bars to the horizontal bars using metal wires, etc., hold the lower ends of the vertical bars at a predetermined height, and secure the horizontal bars and vertical bars. A formwork is arranged around, concrete is poured into the formwork to form an outer wall above an opening such as an entrance and a window, and (b) an outer wall above an opening such as a building entrance and a window. An elongated drainage body was arranged in a part of the formwork facing the opening, and concrete was poured into the formwork, and the drainage body was embedded in the concrete.

[0003]

In the conventional method (a), the vertical reinforcing bar is bound to the horizontal reinforcing bar using a metal wire or the like, and the lower end of the vertical reinforcing bar is held at a predetermined height. If not tied, the lower end is lowered, and the thickness of the reinforcing bar is reduced, or the thickness of the reinforcing bar is completely eliminated, exposing the lower end of the reinforcing bar, and the lower end of the reinforcing bar is rusted after the building is completed. If the reinforcing steel rusts, it will impair the aesthetics of the building.If tiles are attached to the rusting part, rusting will cause the tiles to fall, and the spacers will not be used. There is a disadvantage that the arrangement of the vertical reinforcing bars in the position requires a high degree of skill. In the prior art (b), the draining body is not provided with any means for arranging vertical reinforcing bars at a predetermined height at a predetermined interval. The workability could not be improved. The problem to be solved by the present invention is to provide a space holding member with a drain which can eliminate the above-mentioned disadvantages of the conventional techniques (a) and (b), in other words, to support the vertical reinforcing bars at a predetermined distance. It is an object of the present invention to provide a water draining interval holding body that can maintain the thickness of the lower end of the vertical reinforcing bar constant, improve the workability of the arrangement work, and prevent forgetting to attach the water draining body.

[0004]

The present invention adopts the following structure as means for solving the above-mentioned problems. In the configuration of the present invention, a plurality of bottomed holes are formed at intervals on the opposite side of the drain portion of the elongated rod body having the drain portion, and these holes can fit the ends of the reinforcing bar. Characterized in that there is a spacing member with a drain. In a preferred embodiment: A plurality of protrusions are provided at intervals on the opposite side of the draining portion of the elongated rod having the drainage, and the holes are dimensioned so that the ends of the vertical reinforcing bars can be fitted. If you want to use to maintain the spacing of vertical reinforcing bars of different thickness, configure the bottomed hole with multiple holes of different diameters,
A large diameter hole is located at the entrance side. A bottomed drain groove extending in the longitudinal direction is provided on the lower surface of the elongated rod-shaped body, and a concave or convex stripe extending in the longitudinal direction is provided on at least one of the longitudinally opposed surfaces of the bottomed drain groove. Alternatively, the protrusion or the recess of the mounting piece can be fitted to the protrusion. In the preferred embodiment, the spacing member with a drainer of the present invention is manufactured by integrally molding a plastic material such as a synthetic resin material, but may be manufactured by another material or another molding method. As the synthetic resin material, for example, a hard vinyl chloride resin is used.

[0005]

According to the present invention, the interval holding body with the drainage is provided with a plurality of bottomed holes at intervals on the side opposite to the drainage part of the elongated rod having the drainage part. By fitting in, their spacing is determined naturally,
Even if the binding of the vertical reinforcing bar to the horizontal reinforcing bar is not accurate, the lower end of the vertical reinforcing bar is supported by the bottom of the hole, so that a desired covering thickness can be maintained between the lower end of the vertical reinforcing bar and the concrete surface.
Since the space holding member and the draining member are used at the same time, the number of members can be reduced, forgetting to attach can be prevented, and workability is improved.
