In this scheme, four angles of bolt fastening gasket are equipped with two first extension portions and two second extension portions respectively, all form an inside groove between two liang to make two first extension portions and two second extension portions slightly deform respectively and produce the counter force in the vibrations in-process, make the power on both sides offset each other, realize relatively fixed.

Preferably, the two first extending portions are abutted against the first inner wall surface of the opening channel steel.

Preferably, the two second extending portions are abutted against a second inner wall surface of the opening channel steel, and the second inner wall surface is opposite to the first inner wall surface.

Preferably, the first extending portion and the first inner wall surface of the opening channel steel, and the second extending portion and the second inner wall surface of the opening channel steel are in interference fit respectively.

In this scheme, two first extension portions, two second extension portions of bolt fastening gasket lean on with the first internal face of trompil channel-section steel, the counterbalance of second internal face respectively to adopt interference fit, thereby guarantee that bolt fastening gasket produces the deformation of calculating the direction, the frictional force of production can prevent bolt fastening gasket horizontal direction's removal, improves the locking force.

Preferably, the bolt fixing washer has a through hole, and the bolt nut is inserted into the through hole.

In this scheme, bolt and nut passes through the through-hole and couples together bolt fastening gasket, support pipe clamp and trompil channel-section steel, plays the connection effect.

Preferably, the through hole is located at the middle position of the bolt fixing gasket.

In this scheme, the through-hole is located the intermediate position of bolt fastening gasket, has guaranteed that the frictional force direction size that both sides produced is unanimous to realize preventing removing about bolt fastening gasket.

The positive progress effects of the invention are as follows: this scheme passes through the fastener and fixes the support pipe clamp in the trompil channel-section steel, the fastener includes bolt nut and bolt fastening gasket, bolt nut is with the support pipe clamp, trompil channel-section steel and bolt fastening gasket are connected, bolt fastening gasket installs in trompil channel-section steel internal face, the frictional force that the shape that the bolt fastening gasket four corners extended produced can prevent to control about the gasket horizontal direction at the vibrations corrosion process, bolt nut's not hard up has been avoided, the realization is to support pipe clamp horizontal slip's complete fixation, thereby restrain steel pipe longitudinal movement. In addition, the site operation is convenient, and the gasket type is succinct, and processing is simple and convenient.

Detailed Description

The invention is further illustrated by the following examples, which are not intended to limit the scope of the invention.

As shown in fig. 1, 2, 3, and 4, the present embodiment provides a fixing device for an open-hole channel steel bracket, which includes a bracket pipe clamp 1, an open-hole channel steel 4, and a fastener, where the fastener is used to fix the bracket pipe clamp 1 to the open-hole channel steel 4; the fastener includes bolt and nut 3 and bolt fastening gasket 5, and bolt fastening gasket 5 installs in 4 internal faces of trompil channel-section steel, and bolt and nut 3 connects in support pipe clamp 1, trompil channel-section steel 4 and bolt fastening gasket 5. The looseness of the bolt and the nut 3 in the vibration corrosion process can be prevented, the bracket pipe clamp 1 can be completely fixed in a left-right sliding mode, and therefore the longitudinal movement of the steel pipe 2 is restrained. In addition, the site operation is convenient, and the gasket type is succinct, and processing is simple and convenient.

The four corners of the bolt fixing pad 5 are respectively provided with two first extending portions 51 and two second extending portions 52, and an inner groove 53 is formed between the adjacent first extending portions 51 and the second extending portions 52, between the first extending portions 51 and between the second extending portions 52. The shape of the bolt fixing pad 5 extending around enables the first extension portion 51 and the second extension portion 52 to slightly deform and generate a reverse force respectively in the vibration process, so that the forces on the two sides are mutually offset, and relative fixing is realized.

Both the first extending portions 51 abut against the first inner wall surface 41 of the opening channel 4. The generated frictional force can prevent the bolt fixing shim 5 from moving in the horizontal direction.

Both the second extending portions 52 abut against the second inner wall surface 42 of the opening channel 4, and the second inner wall surface 42 is disposed opposite to the first inner wall surface 41. The generated friction force can prevent the bolt fixing pad 5 from moving left and right in the horizontal direction.
