Description

Building wall pre-buried hole conical bolt

Technical Field

The utility model relates to a building engineering technical field specifically indicates a building wall pre-buried hole toper is tied.

Background

At present, in building installation engineering, when concreting usually, can lay a pre-buried pipe fitting at floor concrete form, but the pipeline can directly be installed after waiting that floor concrete form demolishs, but current pre-buried pipe in use is disposable product, and unable repeated practicality has increased the building engineering cost.

Therefore, the reusable building wall embedded hole conical bolt becomes a problem to be solved urgently.

The utility model aims at providing a repeatedly usable practices thrift construction cost's wall body pre-buried hole toper bolt.

In order to achieve the above purpose, the utility model provides a technical scheme does: the utility model provides a building wall pre-buried hole toper is tied, includes toper bolt, nut and gland, the toper is tied and is the round platform form, toper is tied the center and is equipped with the round hole that runs through the toper bolt, the big head one end and the bolt rotation of toper bolt are connected, the bolt middle part is equipped with the disc, the disc is separated the bolt for outer bolt and interior bolt, the gland overlaps on outer bolt and in outer bolt threaded connection, nut and outer bolt threaded connection.

As an improvement, one end of the big end of the conical bolt is provided with a hollow round table, the diameter of one end of the hollow round table is the same as that of the big end of the conical bolt, and the diameter of the other end of the hollow round table is the same as that of the disc.

As an improvement, a threaded hole is formed in the hollow circular truncated cone, the threaded hole extends into the conical bolt from the hollow circular truncated cone, the threaded hole is in threaded connection with the inner bolt, and the length of the threaded hole is the same as that of the inner bolt.

As an improvement, the inner diameter of the gland is slightly larger than the diameter of the disc, and the gland is sleeved outside the disc.

Compared with the prior art, the utility model the advantage lie in: the utility model discloses environmental protection and energy saving, pre-buried position is accurate, is difficult for the dislocation, and easy operation can recycle, can replace the PVC pipe of traditional use, and the practicality is strong, greatly reduced engineering cost.

Detailed Description

The following will explain the utility model in detail with reference to the attached drawings.

The present invention will be described in detail with reference to the accompanying drawings 1-8.

The utility model provides a building wall pre-buried hole toper is tied, includes that toper is tied 1, bolt 2, nut 3 and gland 4, toper is tied 1 and is the round platform form, 1 center of toper is tied is equipped with the round hole 5 that runs through toper and is tied 1, the big head one end of toper is tied 1 is rotated with bolt 2 and is connected, 2 middle parts of bolt are equipped with disc 6, disc 6 separates bolt 2 for outer bolt 7 and interior bolt 8, gland 4 overlaps on outer bolt 7 and in 7 threaded connection of outer bolt, nut 3 and 7 threaded connection of outer bolt.

The diameter of one end of the hollow round table 9 is the same as that of the big end of the conical bolt 1, and the diameter of the other end of the hollow round table 9 is the same as that of the disc 6.

A threaded hole 10 is formed in the hollow circular truncated cone 9, the threaded hole 10 extends into the conical bolt 1 from the hollow circular truncated cone 9, the threaded hole 10 is in threaded connection with the inner bolt 8, and the length of the threaded hole 10 is the same as that of the inner bolt 8.

The inner diameter of the gland 4 is slightly larger than that of the disc 6, and the gland 4 is sleeved outside the disc 6.

The utility model relates to a concrete implementation process of building wall pre-buried hole toper bolt is as follows:

embedding one end of a small end of the conical bolt 1 into a wall, enabling the large end to be flush with the wall surface, and enabling the inner bolt 8 to penetrate through the template to be matched with the threaded hole 10 of the conical bolt 1 to quickly lock the template; after the template is removed, the inner bolt 8 and the threaded hole 10 are screwed, the gland 4 is sleeved outside the disc 6, when the gland 4 is in contact with the wall surface, a certain gap is reserved between the bottom of the gland 4 and the disc 6, the nut 3 is sleeved on the outer bolt 7, the nut 3 is rotated, the gland 4 is extruded by screwing the nut 3, the gland 4 generates differential pressure on the wall surface, and because the gland 4 is in contact with the wall surface and the inside of the gland 4 has a certain gap with the disc 6, the inner bolt 8 is screwed with the threaded hole 10, the inner bolt 8 drives the conical bolt 1 to be drawn out from the wall body under the pressure; the drawn conical bolt 1 can be repeatedly used for many times, so that the building cost is saved.

The present invention and the embodiments thereof have been described above, but the description is not limited thereto, and the embodiment shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. In summary, those skilled in the art should understand that they should not be limited to the embodiments described above, and that they can design the similar structure and embodiments without departing from the spirit of the invention.
