Description

Adjustable self-tightening channel

Technical Field

The present application relates to a construction element, in particular to an adjustable self-tightening channel.

Background

The channel, also called pre-buried channel, is a commonly used pre-buried part in buildings, and has the same function as the anchor bolt in the building engineering. It can be embedded into concrete in the building construction process to be used for installing and hoisting other civil engineering structural members or electrical members. The channel in the prior art generally comprises a rivet, a T-shaped bolt, C-shaped steel, an antiskid plate, a nut and other structures. Wherein the elements to be installed and hoisted are installed on the exposed part of the T-shaped bolt, and the antiskid plate has the function of enabling the T-shaped bolt not to shift in the channel.

Because the T-bolt is in sliding fit with the C-shaped steel, in order to further prevent skid, it is desirable to increase the friction between the anti-skid plate and the C-shaped steel, for example, a direct means is to increase the positive pressure.

Some solutions have been proposed to increase the positive pressure between the cleat and the C-section steel, such as CN203770307U, which increases the positive pressure by adding a spring between the T-bolt and the cleat. However, in this type of solution, the spring element is defined and the magnitude of the positive pressure is defined and cannot be adjusted to suit the different needs of the various applications.

SUMMERY OF THE UTILITY MODEL

Problem (A)

Provides an anti-slip channel which can be self-tightening and can adjust self-tightening force.

(II) technical scheme

To above-mentioned technical problem, this application provides from tight channel with adjustable, including rivet, C shaped steel, antiskid ribbed tile, this antiskid ribbed tile sets up in the C shaped steel inner chamber, with the contact of C shaped steel inner face, its characterized in that: the anti-skid device is characterized by further comprising a stud, wherein the stud is in threaded fit with the anti-skid plate, and the stud and the anti-skid plate can tightly push the inner surface of the C-shaped steel after being screwed.

Further, the stud is fixed by a nut outside the C-shaped steel.

Furthermore, the stud is also provided with a ridge section.

Furthermore, the stud is also provided with a threaded section.

Further, the top of the stud is a dome.

Furthermore, the hardness of the top of the stud is greater than that of the inner surface of the C-shaped steel.

Preferably, the top of the stud is provided with a groove, the groove comprises a pressing ball, and the stud tightly pushes the C-shaped steel through the pressing ball.

In one step, the hardness of the press balls is greater than the hardness of the inner surface of the C-shaped steel.

(III) advantageous effects

1. The T-shaped bolt in the traditional channel is replaced by the stud, so that the channel system has a self-tightening function under the condition of not increasing elements;

2. the threaded connection design of antiskid ribbed tile and bolt also makes the degree of self-tightening adjustable, is applicable to various building needs.

Detailed Description

The present invention will be further described with reference to the following examples.

As shown in FIG. 1, according to the application, from tight channel with adjustable, including rivet 1, C shaped steel 2, antiskid ribbed tile 4, this antiskid ribbed tile 4 sets up in the C shaped steel inner chamber, with the contact of C shaped steel internal surface, its characterized in that: the anti-skid device is characterized by further comprising a stud 3, the stud 3 is in threaded fit with the anti-skid plate 4, and the stud 3 and the anti-skid plate 4 can be screwed to tightly push against the inner surface of the C-shaped steel 2.

The antiskid of traditional antiskid ribbed tile relies on frictional force or other anti-skidding structures (if have the tooth) between antiskid ribbed tile and the C shaped steel, but frictional force's size is directly proportional to positive pressure, and in this scheme, the double-screw bolt upwards withstands C shaped steel after, continues to close soon, then because double-screw bolt and antiskid ribbed tile also are screw-thread fit, reaches the purpose that increases positive pressure promptly, changes the number of turns of screw in simultaneously and also can adjust the size of positive pressure.

Further, the stud 3 is fixed by a nut 5 outside the C-shaped steel.

Through further fixing of the nut 5, the position of the stud is determined, and the C-shaped steel is prevented from being damaged by stress.

Furthermore, the stud 3 is provided with a ridge section 6.

Further, the stud 3 has a threaded section 7.

The edge section 6 is convenient for screwing during stud installation, and the thread section 7 has the same function as a traditional T-shaped bolt and is used for installing and hoisting basic electromechanical equipment.

Further, the top of the stud 3 is a dome.

Further, the hardness of the top of the stud 3 is greater than that of the inner surface of the C-shaped steel.

The materials with the similar hardness and the local hardness are higher due to the shape of the dome, and the dome-shaped stud is easily pressed into the inner surface of the C-shaped steel, so that reliable compression is achieved, and the anti-skid effect is enhanced by linkage with the anti-skid plate. Of course, other means (e.g., heat treatment) may be used to make the hardness of the stud in whole or in part of the dome greater than that of the C-section steel.

However, such a machining method also increases the manufacturing costs of the stud, so that another simpler way is possible:

furthermore, the top of the stud 3 is provided with a groove, the groove comprises a pressing ball, and the stud tightly pushes the C-shaped steel through the pressing ball.

The design can make the manufacture of the stud easy, and the press ball can use the existing elements, thereby greatly reducing the manufacturing cost.

While one embodiment of the present invention has been described in detail, the description is only a preferred embodiment of the present invention, and should not be considered as limiting the scope of the present invention. All the equivalent changes and improvements made according to the application scope of the present invention should still fall within the patent coverage of the present invention.
