Description

Equipment support fixing device

Technical Field

The utility model relates to an equipment support fixing device.

Background

The equipment in the nuclear power plant is numerous, the equipment needs to be fixed to a concrete plant room through equipment supports, and the equipment supports are fixed to the concrete plant room through embedded parts under general conditions.

According to the manufacturing and construction method of the embedded part in the technical specification (such as 1188JT501) of the nuclear power plant, the conventional equipment support can only be fixed in a concrete plant house in a mode of being welded on an embedded plate, and the welding mode needs a certain operation space, so that the requirement on the quality of construction personnel is high, and the construction time is long. In addition, part of the equipment supports are only used temporarily, and the used equipment supports can be removed only in a cutting mode and cannot be reused, so that the construction cost is increased.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that to prior art exist more than not enough, provide an equipment support fixing device that both had made things convenient for the construction, also was convenient for demolish.

The technical scheme of the equipment bracket fixing device is as follows:

the equipment support fixing device comprises an embedded part and a sleeve, wherein the embedded part is used for pouring in concrete,

the embedded part is provided with a through hole, the inner wall of one end of the sleeve is provided with a thread for connecting with the equipment bracket, and the end of the sleeve with the thread extends out of the through hole.

Preferably, the sleeve is welded in the through hole of the embedded part, and the other end of the sleeve is connected with the anchor bar.

Preferably, the height of the sleeve extending out of the embedded part is the same as the height of a connecting plate of the equipment support.

Further, the device also comprises a protective film which is covered on the end head of the end with the thread of the sleeve.

Preferably, the protective film is made of glass fiber or plastic.

The utility model discloses equipment support fixing device not only can improve the efficiency of construction, can also reduce cost, the energy saving to its bearing capacity also can satisfy the production demand. Particularly, the beneficial effects are as follows:

1) the bolt connection mode is adopted, so that the construction is convenient, and the disassembly is convenient;

2) part of temporarily used equipment supports can be detached after being used, so that the equipment supports can be recycled, and the cost is saved;

3) because the equipment support of the equipment is fixed in the factory building through the fixing device, the position of the equipment support is positioned in advance in the design stage, the secondary lofting positioning is not needed on site, the construction time is saved, and the error of the secondary lofting on site can be avoided.

Detailed Description

In order to make the technical solution of the present invention better understood, the following description of the present invention with reference to the accompanying drawings will be made for clear and complete description of the technical solution of the present invention, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

The utility model provides a device bracket fixing device, which comprises an embedded part poured in concrete and a sleeve,

Example 1

As shown in fig. 1 and 2, the fixing device for the equipment bracket disclosed in this embodiment is mainly applicable to a nuclear industry plant, and includes an embedded part 1 and a sleeve 2.

The embedded part 1 is poured in concrete, and the embedded part 1 is provided with through holes; the sleeve 2 is a special-shaped mechanical sleeve, threads are arranged on the inner wall of one end of the sleeve and used for being connected with a reserved bolt of the equipment support through the threads, and the end, with the threads, of the sleeve extends out of the through hole.

Optionally, the sleeve 2 is welded in the through hole of the embedded part 1, and the other end of the sleeve, which does not extend out of the through hole, is connected with the anchor bar 3 in the embedded part. The height of the sleeve extending out of the embedded part is the same as that of a connecting plate of the equipment support.

The equipment brackets are connected to the sleeves 2 by means of the reserved bolts and are then connectable to the embedded parts, so that the equipment brackets are fixed to the concrete plant.

Optionally, the fixing device further comprises a protective film 4, wherein the protective film 4 covers the end head of the end with the thread of the sleeve, and is used for preventing impurities from entering the sleeve 2 so as to avoid affecting the bolt connection. Preferably, the protective film 4 is made of glass fiber or plastic.

In this embodiment, the sleeve 2 is made of steel. The bore diameter, length and distance of the sleeve 2 can be calculated from the size of the equipment support to which it is attached and the load it transmits.

When construction is carried out, the method is similar to the construction method of the traditional embedded part, the embedded part is fixed on the template after position lofting is accurate, concrete is poured, and the exposed part (namely, one end extending out of the through hole) of the protective film protective sleeve is passed through. After the equipment support is in place, the sleeve and the equipment support are connected by bolts according to the position of the sleeve and the position of a mounting hole reserved in the equipment support, and the bolt is lubricated before being screwed down. If the equipment support needs to be dismantled, the equipment support can be dismantled only by unscrewing the bolts, and the equipment support is convenient and fast to use.

It is to be understood that the above embodiments are merely exemplary embodiments that have been employed to illustrate the principles of the present invention, and that the present invention is not limited thereto. It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit and substance of the invention, and these modifications and improvements are also considered to be within the scope of the invention.
