Description

Technical Field

[0001] The utility model relates to the technical field of steel structure connection, in particular to a flexible connection structure of a steel structure building. Background Art

[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. When connecting steel structures in the construction industry, connectors are usually used to connect multiple steel structures to form a whole.

[0003] For example, Chinese patent CN207771672U discloses a flexible connection clamp for steel structure, which includes a first clamp body and a second clamp body, wherein the first clamp body and the second clamp body are both provided with positioning grooves matching the cross-section of the profile to be connected, and the first clamp body and the second clamp body are both provided with corresponding connecting holes, and the fixing bolts pass through the connecting holes and are locked with nuts to connect the two clamp bodies, and the bottom of the positioning groove is provided with a plurality of nail-shaped protrusions for positioning the profile. The above-mentioned flexible connection clamp for steel structure is not only simple in structure, convenient and flexible in installation, but also has low requirements on the skills and quality of the operator and high in assembly efficiency; at the same time, there are no specific restrictions on the places where it is applicable, and it has good versatility; it is very easy to carry out serialized and standardized mass production.

[0004] However, the above scheme still has certain problems when it is used. Due to the different lengths of steel structures, the weight of the steel structures is different. When connecting a longer steel structure, the connector can only fix a small part of the steel structure, resulting in a greater pressure on the connector. It may cause the connector to be unable to stably fix the steel structure. Therefore, a flexible connection structure of steel structure buildings is proposed to solve the above problem.

[0019] Furthermore, the top wall and the bottom wall of the connection bin are both provided with rotation grooves adapted to the rotation rod, and the connection rope is a nylon rope.
