Embodiment 2

[0064] This embodiment discloses a T-shaped unilateral bolt fastener, such as Figure 5-6 As shown, the shape of the bolt head matches the rectangular installation hole on the steel pipe column and the steel beam end plate, its cross-sectional shape is rectangular, and the top surface of the block part is a rectangular surface matching the installation hole. Other structures and implementation Example 1 is the same.

Embodiment 3

[0066] This embodiment discloses a method of using the T-shaped unilateral bolt fastener described in Embodiment 1 or Embodiment 2: Figure 7-9 As shown, the rectangular or waist-shaped installation holes are pre-processed on the steel pipe column 7 and the steel beam end plate 8, the installation hole on the steel pipe column is the first installation hole 7-1, and the installation hole on the steel beam end plate is the second installation hole. Hole 8-1. The method of using the T-shaped unilateral bolt fastener includes the following steps:

[0067] Step 1: Put the washer on the screw rod, and thread the lock nut to the screw rod. The lock nut should not be screwed in too much, so as to provide installation space for the installation of the block.

[0068] Step 2: Align the bolt head with the installation hole, insert the bolt head through the installation hole into the steel pipe column, rotate the bolt head and screw rod 90°, the bolt head is in contact with the inner su...

Embodiment 4

[0072] This embodiment discloses a T-shaped unilateral bolt fastener, such as Figure 10-11 As shown, the structure is the same as in Embodiment 1 or Embodiment 2, the difference is that the end face of the bolt head is welded with an elongated steel bar 9, one end of the elongated steel bar is welded and fixed with the bolt head, and the other end is fixed with an anchor head 10, which increases the amount of concrete in the steel pipe. The anchoring effect makes the fastening strength of the fastener higher.

Abstract

The invention relates to a T-shaped single side bolt fastening part and a use method. The T-shaped single side bolt fastening part comprises a bolt rod and a bolt head which are integrally connected,a clamping block and a locking nut, wherein the bolt head can penetrate through rectangular or waist-shaped installation holes arranged in a steel beam end plate and a steel vertical column and penetrates into the steel vertical column to rotate a set angle to be capable of contacting with the inner side face of the steel vertical column, the bolt rod is provided with a groove in the axis direction of the bolt rod, and on the same section of the bolt rod, a connection line, perpendicular to the groove bottom face, between the groove bottom face and the bolt rod section circle center and a longaxis line of the bolt head are in included-angle arrangement; the clamping block comprises a clamping block portion, the bottom face of the clamping block portion is provided with a clamping block convex rib, the clamping block portion can be slidably connected with the bolt rod, the two sides of the clamping block convex rib are provided with clamping limbs fixedly connected with the clamping block portion, the clamping limbs can contact with the end face of the bolt head, and the clamping block can be placed into the installation holes and contacts with the hole faces of the installation holes; and the locking nut can be in threaded connection with the bolt rod. The T-shaped single side bolt fastening part is convenient to construct and high in bearing force.

Description

technical field [0001] The invention relates to the technical fields of civil engineering and mechanical assembly parts, in particular to a T-shaped unilateral bolt fastener and a use method thereof. Background technique [0002] One of the characteristics of prefabricated buildings is the factory production of components and the assembly of on-site construction. Steel structure buildings have basically realized the factory manufacturing of components, but there are still a lot of welding operations for on-site installation, such as the bolt welding connection of steel frame columns and steel beam nodes. Therefore, it is of great scientific significance and engineering practice value to further improve the on-site assembly rate of steel structures and to research and develop new types of assembled joints. [0003] In steel structure buildings, it is more advantageous to use steel pipe sections for frame columns, such as high bending rigidity and torsional rigidity of the se...
