Inverted-triangular steel tube intersected spatial truss and assembly method thereof

Abstract

The invention discloses an assembly method of an inverted-triangular steel tube intersected spatial truss, and is used for solving the problems existing in the prior art that the inverted-triangular steel tube intersected spatial truss is unreasonable in structure, and is inconvenient in operation while blanking and assembling. The inverted-triangular steel tube intersected spatial truss comprises a pre-embedded steel plate (7) arranged on the top surface of a concrete support (2), and a crisscross supporting ribbed plate rack (8) fixedly welded on a hollow sphere supporting bottom plate (3), wherein the pre-embedded steel plate (7) is fixedly connected with the hollow sphere supporting bottom plate (3) by bolts (6) and nuts (1), a hollow sphere (9) is welded on the circular arc top surface of the crisscross supporting ribbed plate rack (8), steel tubes (5) forming inverted-triangular sides are fixedly welded in node holes (10) of the hollow sphere, and a connection steel plate is welded between the peaks of the steel tubes (5) forming the inverted-triangular sides. The inverted-triangular steel tube intersected spatial truss is convenient to construct and produce, and economical in material consumption.

Description

technical field [0001] The invention relates to a support frame for a building ceiling, in particular to an inverted triangular steel pipe intersecting three-dimensional truss and an assembly method thereof. Background technique [0002] With the development of society, the demand for the functional characteristics of buildings (structures) is also getting higher and higher. It has become the current requirement to increase the structural size of buildings, increase the use space of buildings, and make the appearance and structure of buildings novel and beautiful. In order to meet this need, the three-dimensional truss of steel structure has been developed rapidly in the field of construction. In the prior art, the structure of the three-dimensional truss is unreasonable in the construction of the steel pipe intersecting three-dimensional truss, and there are problems of difficult operation and inconvenient operation when cutting, assembling and installing the inverted tri...
