2. Description of the Related Art In a building with a basement floor, the bottom plate in contact with the ground is affected by groundwater, and groundwater that permeates from the basement and accumulates on the bottom plate is provided with a through hole in an underground foundation beam, collected at one place, and pumped. It is common to drain water. Usually, a plurality of the through holes are provided for one foundation beam, and as an installation method, a plastic pipe having a circular or semicircular cross section is buried in the foundation beam in the horizontal direction.

In the conventional method of burying a plastic pipe in a horizontal direction in a foundation beam, since a large number of buried portions have a sectional defect, reinforcement is provided around the buried portions. For this reason, the labor of arranging the reinforcing bars is very difficult, and the reinforcing bars are often not sufficiently reinforced.

DISCLOSURE OF THE INVENTION The present invention is a metal fitting for an underground foundation beam through-hole which does not require a separate reinforcing bar arrangement as in the conventional method. That is, the present invention provides a through-hole for an underground foundation beam in which a plurality of sets of three reinforcing bars are welded by projecting to both sides of the width in the width direction of each side of a triangular prism in which both flange ends of an angle iron are welded to an elongated steel plate. It depends on hardware.

In the metal fittings for through-holes of underground foundation beams according to the present invention, the reinforcing bars projecting from both sides in the width direction of each side surface of the triangular prism are welded to serve as a jig for mounting the metal fittings and as a reinforcing bar. In addition, the triangular prism composed of the angle iron and the steel plate also serves as a reinforcing material and a through hole.

Therefore, when the metal for the underground foundation beam penetration hole of the present invention is buried in the foundation beam in the horizontal direction, the beam concrete naturally has a cross-sectional defect. It is more than complemented by the reinforcing effect of steel, steel plates and rebar. As a result, the use of the metal fittings for through-holes of underground foundation beams of the present invention eliminates the necessity of any additional reinforcing bars even when the number of through-holes is large.

[0007] Since the hardware of the present invention can be installed in the formwork only by binding the welded rebar to the stirrup, the labor for installation is also reduced.
