Steel/wood combined truss connection structure

Abstract

The invention discloses a steel / wood combined truss connection structure. The steel / wood combined truss connection structure comprises two upper chord members, a first vertical web member, second vertical web members, diagonal web members, first lower chord members, second lower chord members, and a connecting piece; the connecting piece comprises a supporting block, installation blocks, first connecting blocks, second connecting blocks, third connecting blocks, fourth connecting blocks, fifth connecting blocks, sixth connecting blocks, seventh connecting blocks, eighth connecting blocks, first fixing blocks, second fixing blocks, bolts, and rotating members; the supporting block is of a pentagonal prism structure; the two first connecting blocks are symmetrically fixedly arranged on thetwo sides of the lower [art of the supporting block. According to the steel / wood combined truss connection structure, the upper chord members, the first vertical web member, the second vertical web members, the diagonal web members, the first lower chord members, and the second lower chord members are be fixed, a conventional notch and tooth joint manner is avoided, welding connection is avoided,the connection precision among the members is higher, the structure is more compact, no welding joint or welding rust is generated, and the appearance is beautiful.

Description

technical field [0001] The invention relates to the connection structure and technical field of a steel-wood composite truss, in particular to a connection structure of a steel-wood composite truss. Background technique [0002] The connection between the wooden components in the truss mainly adopts tooth connection, that is, the two wooden components are processed into tooth-like structures corresponding to concave and convex at the joint, and the load is transferred by mutual fit. The problem is that the processing of the tooth-shaped part is difficult, the precision control is high, and the quality is not easy to control; because it is difficult to ensure that the tooth-shaped joints of the joints are well matched due to tooth-shaped processing and on-site installation, it is easy to transmit uneven force, resulting in The local load at the node is too large, causing unexpected damage to the connection, endangering the safety of property and life. In addition, due to the...

Problems solved by technology

In short, on-site production is time-consuming and labor-intensive, which is contrary to the development trend of building prefabrication

[0004] When the development of modern buildings is changing with each passing day, the inherent connection form of traditional steel-wood trusses results in the style of trusses and the solidification of details, which can no longer meet people's individual aesthetic requirements.

For example, there is a design requirement that the upper chord of the truss needs to be cantilevered as a cantilever, which cannot be met by traditional nodes; there is a design requirement that the lower end of the vertical wooden web of the truss needs to exceed the effect of the lower chord pointing downward, which cannot be satisfied by traditional nodes, etc.
