Problems solved by technology

However, for special structures, such as closed tubular structures or structures that are not easily accessible at one end, the use of ordinary bolts is greatly restricted.
In order to overcome the deficiency that existing bolts cannot be fastened from one side, there are currently existing bolt fastening assemblies capable of one-way fastening from one side and an assembly method thereof

Embodiment 1

[0023] The structure diagram of this embodiment is as figure 1 and figure 2 Show. The cross sections of the outer steel pipe 1 and the inner steel pipe 2 are circular, the end plate assembly 4 is an arc-shaped end plate, and the steel beam 5 is an I-shaped steel beam. The one-way fastening bolt assembly 6 passes through the holes reserved on the outer steel pipe 1 and the inner steel pipe 2 and is tightened; hoist the steel beam 5 to the designated position, one end of the end plate assembly 4 is close to the pipe wall of the outer steel pipe 1, and the other The side is connected to the steel beam 5, and the end plate assembly 4 and the steel beam 5 are fixed to the outer steel pipe 1 and the inner steel pipe 2 with the one-way fastening bolt assembly 6, and then the interlayer concrete 3 is poured to complete the construction of the node.

Embodiment 2

[0025] The structure diagram of this embodiment is as image 3 and Figure 4 Show. The difference from Example 1 is that both the inner steel pipe 2 and the outer steel pipe 1 in this embodiment use square steel pipes, the end plate assembly 4 is T-shaped, and the outer steel pipe wall is welded with a shear web 7, and the end plate assembly 4 The 5 steel beams are connected by bolts.

Abstract

The invention relates to the field of structural engineering in civil engineering, in particular to a hollow sandwich filled steel tubular column-a steel beam connection adopting a one-way fastening bolt. The one-way fastening bolt component passes through an inner steel tube and an outer steel tube on one side, one end of an end plate component is abutted against the wall of the outer hollow sandwich filled steel tube, and an inner steel tube and an outer steel tube on the other side are connected with a steel beam. During construction, the inner steel tubes and the outer steel tubes are preserved with holes; then the bolt component passes through the end plate and the holes on the steel tubes and is screwed; and finally, sandwich concrete is poured to finish the construction of the connection. The connection has definite force transmission, reliable performance, convenient construction and good economy and is suitable for high-rise and large-span buildings and other relevant buildings.

Description

technical field [0001] The invention relates to the field of structural engineering in civil engineering, in particular to a type of hollow interlayer steel pipe concrete column-steel beam joint using a one-way fastening bolt assembly. Background technique [0002] Hollow interlayer concrete filled steel pipe is a component formed by placing two layers of steel pipes concentrically and pouring concrete between the two layers of steel pipes. It is suitable for supporting columns of offshore platforms, bridge piers, large-diameter columns in high-rise buildings, and other related high-rise structures and structures. column member. The design of the beam-column joints of the hollow sandwich concrete filled steel tube structure directly affects the overall stiffness, mechanical performance and safety of the structure, and also affects the construction of the structure, so it becomes a key link in the design of this type of structure. However, because the hollow interlayer concr...
