[0004] Although the above-mentioned steel pipe outer wall is clamped by screwing the two screw rods, when the two screw rods are screwed in turn, the moving distance of the two screw rods is not consistent, which causes the moving range of one of the engaging blocks to be larger and pushes the steel pipe to one side, so that the steel pipe cannot be centered, and the clamping force of the two engaging blocks is not symmetrical, which causes the clamping force to be uneven, affecting the stability of the steel pipe.

[0005] Therefore, a building steel structure connecting device is proposed to solve the above problems. Utility model content

[0006] The purpose of the utility model is to provide a building steel structure connecting device to solve the above problems, and improve the problem that the steel pipe is easily offset from the center during fixing, causing uneven clamping force on both sides of the steel pipe and affecting the stability of the steel pipe.

Through first clamping plate, second clamping plate and rubber pad, realized when connecting steel pipe, the inner chamber of steel pipe is inserted connecting shell and the one side of first clamping plate is attached, again through three second clamping plates the other side and top and bottom of steel pipe are fixed, and when steel pipe is connected, through the movement of one of second clamping plates, and the other two second clamping plates will subsequently simultaneously clamp the top and bottom of steel pipe, when first clamping plate and second clamping plate clamp the outer wall of steel pipe, through rubber pad increase the friction between first clamping plate and second clamping plate and steel pipe, make it in the process of clamping steel pipe not appear the phenomenon of sliding, because first clamping plate is in fixed state, when one of clamping plates clamps the one side of steel pipe, and steel pipe also will not appear the phenomenon of deviation, improved the stability of steel pipe when connecting.

[0008] Preferably, the connecting mechanism further comprises a screw rod threadedly connected to one side of the positioning shell, the other end of the screw rod penetrates into the inner cavity of the positioning shell and is fixedly connected with an extrusion cylinder, the outer surface of the extrusion cylinder is slidably connected to one side of the connecting shell, the inner cavity of the extrusion cylinder is provided with a first piston, one side of the first piston is fixedly connected with an extrusion rod, and the other end of the extrusion rod is fixedly connected with one side of one of the second clamping plates. Through the screw rod, the extrusion cylinder, the first piston and the extrusion rod, the screw rod is twisted to drive the extrusion cylinder to move, so that the extrusion rod drives one of the second clamping plates to clamp one side of the steel pipe.

[0009] Preferably, the connecting mechanism further comprises a flow guide pipe communicated with the top and bottom of the extrusion cylinder, the other end of the flow guide pipe is communicated with a collecting cylinder, the bottom and top of the two collecting cylinders are fixedly connected with the top and bottom of the connecting shell respectively, the inner cavity of the collecting cylinder is provided with a second piston, one side of the second piston is fixedly connected with an auxiliary rod, and the other end of the two auxiliary rods penetrates through the collecting cylinder and is fixedly connected with one side of the other two second clamping plates.

[0010] Preferably, one end of the extrusion cylinder is fixedly connected with a tension spring, and the other end of the tension spring is fixedly connected with one side of one of the second clamping plates.

[0011] Through the tension spring, when the tension spring has no extrusion degree, the first piston is driven to rebound and move, thereby driving the first piston to suck back the gas in the collecting cylinder, so that the three second clamping plates shrink and move away from the surface of the steel pipe, thereby disassembling the steel pipe.

When the steel pipe is connected, one of the second clamping plates is moved, and the other two second clamping plates will simultaneously clamp the top and the bottom of the steel pipe. Since the first clamping plate is in a fixed state, the steel pipe will not deviate when one of the clamping plates clamps one side of the steel pipe, thereby improving the stability of the steel pipe during connection. The connection mode of the steel pipe avoids the problems that the conventional connection mode easily causes the steel pipe to deviate and the clamping force on both sides is inconsistent when the steel pipe is connected.

[0017] When the steel pipe is vibrated by external influence during use after connection, when the steel pipe is agitated to left and right sides, the extrusion force will extrude the extrusion rod again, and the extrusion rod will drive the first piston to extrude the gas in the extrusion cylinder into the collecting cylinder again, and the gas will push the second piston to drive the second clamping plate at one end of the auxiliary rod to apply extrusion force to the top and bottom of the steel pipe again, when the steel pipe is agitated up and down, similarly, the steel pipe applies pressure to the auxiliary rod through extrusion force, and the second piston extrudes the gas in the collecting cylinder back into the extrusion cylinder, and the gas pushes the second clamping plate at one end of the extrusion rod to apply pressure to one side of the steel pipe again, so that the steel pipe is repeatedly clamped by the three second clamping plates when the steel pipe is agitated, the stability of the steel pipe during use is improved, and the shock generated by the agitation can be buffered by the first piston and the second piston.
