Abstract

The invention discloses a hollowed-out circular-ring-shaped space grid structure assembly type joint. The hollowed-out circular-ring-shaped space grid structure assembly type joint comprises a center hollowed-out circular ring (1), a joint inner gasket (2), a seal plate (3), a connection rod part (4) and a bolt (7). The seal plate is provided with a bolt hole. The section of the center hollowed-out circular ring is provided with a first hollowed-out hole (6). The two sides of the first hollowed-out hole are each provided with a second hollowed-out hole (5). The first hollowed-out hole is in an isosceles trapezoid shape. The four edges of the first hollowed-out hole all have certain radian. The peripheral wall of the first hollowed-out hole is provided with bolt holes. The second hollowed-out holes are in a triangular shape, and the three edges of each second hollowed-out hole have certain radian. The center hollowed-out circular ring, the seal plate and the connection rod part are connected through bolts, and an assembly type rod part is formed. The hollowed-out circular-ring-shaped space grid structure assembly type joint has wide application prospects in single-layer triangular space grid structure lighting roofs.

Description

technical field [0001] The invention relates to the technical field of spatial structure design in the construction industry, in particular to an assembled node of a hollowed-out circular space grid structure. Background technique [0002] With the rapid development of economy and society, the construction industry is becoming more and more prosperous. Many large-span spatial structures with different shapes and unique styles have sprung up all over the country. The proportion of less pollution in the long-span spatial structure is also getting heavier. Therefore, as an important part of the prefabricated space grid structure, the prefabricated node has naturally attracted widespread attention, attracting a large number of scholars and technicians to develop and manufacture, in order to obtain a space structure prefabricated node with more efficient assembly and superior performance. form. The prefabricated nodes in the prior art have a large dead weight, and the assemblin...
