Abstract

The utility model discloses a pre-buried PVC pipe for shaping grout hole, including the body, the body lower extreme seals, and the body corresponds along its length direction and is equipped with the recess that three interval set up and encircle body circumference outer wall, and the recess is slant annular structure, recess and tie up iron wire diameter adaptation. This a pre-buried PVC pipe for shaping grout hole makes things convenient for the shaping to satisfy the grout hole of designing requirement.

Description

A pre-buried PVC pipe for shaping grout hole

The technical field is as follows:

the utility model relates to a building, specifically say a pre-buried PVC pipe for shaping grout hole.

Background art:

among the prior art, need use pre-buried PVC pipe at a supporting beam shaping grout hole, nevertheless current PVC pipe need be with its bottom sealing process when pouring concrete after pre-buried, if handle improper and cause the hourglass thick liquid easily to the difficult steel of PVC pipe is tied up on a supporting beam's stirrup, causes the body come-up easily when pouring, thereby causes the degree of depth in fashioned grout hole to reach the designing requirement.

The utility model has the following contents:

the utility model aims to solve the technical problem that a pre-buried PVC pipe for shaping grout hole that facilitates use is provided.

The technical solution of the utility model is that, a pre-buried PVC pipe for shaping grout hole is provided, including the body, the body lower extreme seals, and the body corresponds along its length direction and is equipped with the recess that three interval set up and encircle body circumference outer wall, and the recess is slant annular structure, recess and tie up iron wire diameter adaptation.

Compared with the prior art after the structure more than adopting, the utility model has the advantages of it is following: when the grouting hole is formed in the supporting beam, the pipe body is bound on the stirrup of the supporting beam through the iron wire through the groove, then concrete is poured, and the pipe body is prevented from displacing, so that the grouting hole is formed better, and the grouting hole meets the design requirements.

Preferably, the lower end of the tube is recessed downwardly to form a spherical surface. Is convenient for integral molding.

Description of the drawings:

fig. 1 is a schematic structural diagram of the present invention.

Fig. 2 is a usage effect diagram of the utility model.

The specific implementation mode is as follows:

the invention will be further explained with reference to the drawings and the detailed description below:

as shown in figures 1 and 2, a pre-buried PVC pipe for shaping grout hole, including

body

1, 1 lower extreme of body seals, and body 1 corresponds along its length direction and is equipped with three interval setting and encircles the recess 2 of body circumference outer wall, and recess 2 is slant annular structure, recess 2 and 3 diameter adaptations of iron wire. Specifically, the PVC plastic tubing is cut into fixed length, and length is generally for exceeding 100mm ~ 200mm of roof beam face, at a supporting beam's reinforcement stage, fixes the PVC pipe on the stirrup 4 of roof beam according to the design position: the distance between the bottom of the pipe and the bottom surface of the beam is 100 mmm; and (3) binding and fixing three iron wires (the first way is about 100mm away from the bottom of the pipe, the middle part of the second way is a beam gluten, the third way is a beam gluten), pouring concrete, and taking out the PVC pipe after the concrete is initially set so as to form a grouting hole. In addition, in order to facilitate the forming of the tube body, the end part of the lower end of the tube body is downwards sunken to form a spherical surface.

Through above-mentioned structure, the body lower extreme need not to recycle waterproof sticky tape and seals the processing, and one raises the efficiency, and two can avoid sealing the condition emergence that handles not in place, simultaneously, sets up the adaptation recess of tying up the iron wire, avoids taking place the displacement after the iron wire is tied up.

The foregoing is illustrative of the preferred embodiments of the present invention only, and is not to be construed as limiting the claims. All the equivalent structures or equivalent flow changes made by using the contents of the specification and the attached drawings of the utility model are included in the patent protection scope of the utility model.

Claims

1. The utility model provides a pre-buried PVC pipe for shaping grout hole, includes the body, its characterized in that: the lower end of the pipe body is closed, three grooves which are arranged at intervals and surround the outer wall of the circumference of the pipe body are correspondingly arranged on the pipe body along the length direction of the pipe body, the grooves are of an inclined annular structure, and the grooves are matched with the diameter of the bundled iron wires.

2. The pre-buried PVC pipe for forming a grouting hole according to claim 1, which is characterized in that: the lower end of the tube body is recessed downwards to form a spherical surface.
