Description

DETAILED DESCRIPTION OF THE INVENTION In the case of underground concrete pipes, they are used for multiple purposes such as for sewerage and electric wires, but in the past, separate pipes were mainly laid underground, which was uneconomical.

The present invention was proposed in order to eliminate such drawbacks, and after laying a concrete pipe, the upper and lower opening ends of the recessed parts arranged in rows along the upper and lower edges are installed with mounting plates having through holes. Anchor plugs are set on the upper and lower surfaces of the inner wall of the concrete pipe at positions corresponding to the through holes of the mounting plate in the covered precast concrete partition wall, and then the partition wall is carried into the concrete pipe and the mounting plate is inserted into the precast concrete partition wall. The present invention relates to a method for attaching a partition wall to a concrete pipe, characterized in that a bolt inserted through a through hole is screwed onto the plug.

In the present invention, as described above, a precast concrete partition wall is used in which concave notches are arranged in a row on the upper and lower edges, and each of the concave notches is covered with a mounting plate having a through hole. After laying the concrete pipe at the specified location, anchor plugs are set on the top and bottom of the inner wall of the concrete pipe at positions corresponding to the through holes in the upper and lower mounting plates of the bulkhead, and then the bulkhead is carried into the concrete pipe and the bulkhead is installed. By inserting the bolt into the through hole of the mounting plate using the concave notch and screwing it into the plug,
A partition wall can be easily and accurately attached to a concrete pipe.

As described above, according to the present invention, a partition wall can be easily attached to a concrete pipe, and the inside of the concrete is divided into a plurality of pipes by the partition wall, and the pipe can be used for a plurality of purposes, which is economical. Furthermore, the present invention has many advantages, such as the fact that the construction work for the same plurality of pipelines can be completed only once.

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

A is a precast concrete partition wall, in which concave notches 2 are arranged in rows along the upper and lower edges of a rectangular main plate 1,
The through holes 3 are arranged so as to close the opening end surfaces of the respective recessed notches 2.
A mounting plate 3 having a shape is integrally anchored to the bulkhead main plate 1.

After the concrete pipe B is laid at a predetermined position, concrete anchor plugs 4 are set on the upper and lower surfaces of the inner circumferential wall of the pipe B at locations corresponding to the through holes 3a of the mounting plate 3 of the partition wall A. The plug 4 can be easily set on the inner wall surface of the concrete pipe B using a commercially available all-anchor or hole-in anchor (both trade names).

Next, the partition wall A is carried into the concrete pipe B, and the bolts 5 are inserted into the through holes 3a of the mounting plate B through the notches 2.
The partition wall A is attached to the concrete pipe B by penetrating it and screwing it onto the plug 4, filling mortar 6 between the concrete pipe B and the mounting plate 3 of the partition wall A.
Note that the invert 7 will be placed in concrete if necessary.

In the illustrated embodiment, the partition wall A is installed at the center of the concrete pipe B, but it can be adapted to various uses by shifting it to one side to make the left and right spatial areas of the pipe different. For example, when used in a separate sewage culvert, the amount of sewage flowing down is different from the amount of rainwater.

Although the illustrated embodiments of the present invention have been described above, the present invention is, of course, not limited to these embodiments, and can be modified in various ways without departing from the spirit of the present invention. It is.
