Abstract

(57) [Summary] [Purpose] It is not necessary to reinforce the column concrete that accompanies the formation of a gutter through the underground column. [Structure] An underground pillar penetrating gutter metal fitting in which the ends of both flanges of angle steel are welded to an elongated steel plate to form a triangular prism.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to the material and structure of a metal article for a gutter through an underground column.

[0002]

[Prior art]

 In a building with a basement floor, the wall surface in contact with the ground is affected by groundwater, and the groundwater that has penetrated into the outer peripheral wall is generally collected in one place by a gutter provided along the wall and drained by a pump. At this time, it is necessary to make the gutter penetrate the underground part of the pillar. Of course, there is a method of installing the gutter which does not penetrate the pillar, but the pillar is often penetrated for various reasons. A plastic pipe with a circular or semi-circular cross section is embedded horizontally in the pillar as a side groove that penetrates the pillar.

[0003]

[Problems to be solved by the device]

 In the conventional method of horizontally burying a plastic pipe in a column, the burial site causes a column cross-section loss, so structural examination is necessary, and if necessary, increase the concrete cross section and / or around the plastic pipe. Measures such as providing reinforcement bars have been taken.

[0004]

[Means for Solving the Problems]

 The present invention is a post-penetrating groove metal fitting that does not require special reinforcement measures unlike the conventional method. That is, the present invention relates to an underground pillar through-side groove metal fitting which is formed by welding the ends of both flanges of chevron steel to an elongated steel plate to form a triangular prism.

When the underground pillar penetrating gutter hardware of the present invention is buried horizontally in a column, naturally, a section defect occurs in the column concrete, but the decrease in the column section function due to the section loss causes the buried angle steel to be buried. It is more than complemented by the reinforcing effect of the steel sheet. Therefore, by using the metal fittings for the through-ditch of the underground column according to the present invention, no special reinforcement measure as in the conventional method is required.

Further, the metal fitting of the present invention can be easily made by welding angle iron and a steel plate, and can be easily installed in the mold, and the economic effect of using the metal fitting of the present invention is great.

【Example】

 The present invention will be described below with reference to the drawings.

FIG. 1 shows an example of a metal article for a through groove of an underground pillar of the present invention, (a) is an elevation view and (b) is a plan view.

The underground pillar penetrating gutter metal 1 of FIG. 1 is a standard one for the underground pillar penetrating gutter metal, and the ends of both flanges of the angle steel 2 are welded to the elongated steel plate 3 to be integrated into a triangular prism shape. The triangular opening serves as the side groove 4. In FIG. 1, angle irons 2 having equilateral sides are used, but unequal sides may be used.

2A and 2B show a state in which the metal article 1 for a groove for penetrating an underground pillar of the present invention is installed in a mold, (a) is a longitudinal sectional view, and (b) is a view taken along the line AA of (a). is there.

The underground pillar penetrating gutter metal fitting 1 is formed with the steel plate 3 facing down with the drainage gutter 4 provided along the underground outer wall 6 between the underground outer wall 6 and the inner wall 7 in line with the height. It is installed and fixed by binding it to the hoop reinforcements of columns and other reinforcement reinforcements.

[0012]

[Effect of device]

 The underground pillar penetrating gutter metal fitting of the present invention is easily manufactured from angle steel and a steel plate. When this underground pillar penetrating groove metal fitting is used, it is not necessary to reinforce the column concrete in the gutter penetrating portion.
