Abstract

The invention relates to a blind hole embedded part and a construction method thereof, wherein the blind hole embedded part comprises: the pipe body is embedded in the concrete structure, the inside of the pipe body is hollow and is communicated up and down, and internal threads are formed on the inner wall of the pipe body; a bolt screwed in the pipe body; and the liquid filling material is filled in the gap between the pipe body and the bolt and is solidified into a filling layer for plugging the gap between the pipe body and the bolt and covering the top of the bolt. The filling layer prevents the damage caused by impurities and slurry flowing into the pipe body in the subsequent concrete pouring process, thereby solving the problem that the internal thread of the pipe body in the construction engineering is difficult to protect. After the concrete is poured, the paraffin is heated and melted by the hydration heat of the concrete, so that the top of the pipe body is completely exposed, and the subsequent use is facilitated. In addition, the paraffin which is not cleaned in the gap of the residual pipe body has a lubricating function and does not influence the subsequent use function.

Detailed ways

The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

Referring to FIG. 1, there is shown an elevation view of the blind via embedded part of the present invention. FIG. 2 is a plan view of the blind hole embedded component of the present invention. 1 and 2, the blind hole embedded part of the present invention includes:

The pipe body 10 embedded in the concrete structure, the interior of the pipe body 10 is hollow and penetrates up and down, and the inner wall of the pipe body 10 is formed with internal threads;

a bolt 20 screwed into the body 10; and

The liquid filling material fills the gap between the pipe body 10 and the bolt 20 , and solidifies into a filling layer 30 that blocks the gap between the pipe body 10 and the bolt 20 and covers the top of the bolt 20 .

As a preferred embodiment of the embedded part of the blind hole of the present invention, the filling material is paraffin. Paraffin wax is obtained by solvent refining, solvent dewaxing, or freezing crystallization of wax, dewaxing by pressing, and dewaxing of lubricating oil fractions obtained from crude oil distillation to obtain wax paste, which is then deoiled and supplemented with flake or needle-shaped crystals obtained by refining.

As a preferred embodiment of the blind hole embedded component of the present invention, the top surface of the filling layer 30 is higher than the top of the tube body 10 and covers the top edge of the tube body 10 .

As a preferred embodiment of the blind-hole embedded member of the present invention, referring to FIG. 3 is a top view of the blind-hole embedded member of the present invention. 3 , the bottom end of the pipe body 10 is blocked and fixed with a lower end plate 11 ; the top end of the pipe body 10 is fixed with an upper end plate 12 , and the upper end plate 12 is formed with an opening corresponding to the pipe body 10 .

Specifically, the pipe body 10 is a stainless steel pipe with internal threads formed on the inner wall. Screw the matching bolts into the pipe body 10.

Use liquid paraffin to fill the gap between the bolt and the inner wall of the pipe, and ensure that the paraffin is 1-2cm higher than the top of the top plate of the embedded part, so as to ensure the sealing of the pipe body and prevent concrete from falling into the pipe body and damaging the threads and bolts.

After the concrete is poured, make full use of the heat of concrete hydration to melt most of the paraffin, especially the top. By screwing into the pipe body in advance, filling the gap with liquid paraffin and covering the top of the pipe body for protection, a filling layer is formed for sealing, so as to ensure that no impurities and slurry will flow into the concrete construction process and prevent damage.

Liquid paraffin has a low melting point, usually at 49-51 °C, and loses fluidity after curing. However, the heat of hydration can cause the paraffin to melt, which can cause the top of the pipe body to be completely exposed, which solves the problem that the internal thread of the pipe body is difficult to protect during construction projects. The problem.

In addition, the uncleaned paraffin wax in the gap of the remaining pipe body has its own lubricating function and does not affect its subsequent use function.

First, in the process of pouring the concrete structure, the pipe body as the embedded part is set in the formwork of the concrete structure to be poured according to the design requirements. Internal threads are formed in the pipe body for subsequent installation and connection.

According to the size of the pipe body, select the appropriate bolts for installation. The bolt is inserted into the pipe body and screwed with the inner thread in the pipe body.

Heat the paraffin to a liquid state, use a special needle to pick paraffin and fill it in the gap between the pipe body and the bolt. The top is completely covered, and after the liquid paraffin solidifies, it will form a filling layer that seals the gap between the pipe body and the bolt and covers the top of the bolt. After the liquid paraffin has cured, clean up the surroundings.

After the above-mentioned embedded parts are set, concrete is poured. After the concrete is poured, the paraffin is heated and melted by the hydration heat of the concrete, and the paraffin on the surface layer can be cleaned with cotton cloth.
