Embodiment 1

[0036] This embodiment provides a method for manufacturing a rigid node 1 of a single-layer reticulated dome, the method comprising steps:

[0037] Assemble a lost pattern with the same shape and size as rigid node 1.

[0038] Manufacture a sand shell with a core matching the shape and size of the lost foam;

[0039] Rigid node 1 is formed by casting.

[0040] Therefore, the rigid node 1 of the single-layer reticulated shell with various angles is directly formed integrally by the lost foam casting, the structural integrity is better, there is no connection stress concentration point, and the mechanical properties of the rigid node 1 are better. At the same time, the work intensity of workers is reduced, the processing efficiency is improved, and the processing cost is reduced.

[0041] Step S101 , assembling an evaporative pattern with the same shape and size as the rigid node 1 .

[0042] To produce the rigid node 1 by casting, it is necessary to solve the problem of cooper...

Embodiment 2

[0078] The present invention also provides a method for manufacturing a single-layer reticulated dome. The single-layer reticulated dome includes a rigid node 1 and a rod 10 . The rod 10 is connected to the rigid node 1 by connecting the connecting arm 12 of the rigid node 1 . The rigid node 1 is manufactured by the above-mentioned manufacturing method, and the rods 10 are connected to the rigid node 1 by welding to form a single-layer reticulated shell with a curved surface shape.

[0079] In this embodiment, the method for manufacturing a single-layer reticulated shell includes steps:

[0080] Make Rigid Node 1;

[0081] Spatial positioning of adjacent rigid nodes 1;

[0082] The rod 10 is welded on the rigid node 1.

[0083] In structural assembly, it is first necessary to spatially locate adjacent rigid nodes 1 of the single-layer shell structure and temporarily fix them, and then hoist the rods 10 between each rigid node 1 between adjacent rigid nodes 1 . The rod 10 a...

Abstract

The invention provides a method of producing a rigid joint of a single-layer reticulated shell. The rigid joint comprises a rigid joint body and a plurality of connecting arms connected on the rigid joint body, and the method includes the steps that a lost foam with the same shape and size as the rigid joint is assembled; a sand shell of mold core matched the shape and size of the lost foam is produced; and the rigid joint is cast molding. A method of producing a single-layer reticulated shell comprises that the single-layer reticulated shell includes the rigid joint and rod pieces, and a plurality of rod pieces are connected in a gridding shape; and the rigid joint is cast by the lost foam, and connected the rod pieces with the rigid joint through welding. The single-layer reticulated shell and the rigid joint produced by the method of producing single-layer reticulated shell and the rigid joint thereof has the advantages of being high in production efficiency, low labor in intensity,greatly reducing 7in the technical proficiency of workers, and very suitable for building components producing industry with large batch demand.

Description

technical field [0001] The invention relates to the field of connecting components of building structures, in particular to a method for manufacturing a single-layer reticulated shell and its rigid nodes. Background technique [0002] The single-layer reticulated shell is a special form of space steel structure. It is named because it has only one layer of steel components under the building skin. Through the shape change of the building surface, the single-layer reticulated shell can achieve an extremely light and light architectural aesthetic. In recent years, it is often used in commercial buildings with strong decoration as a daylighting roof for large public spaces. [0003] Generally, all the steel structural members of a single-layer reticulated shell have the same appearance cross-sectional size, and the local support position can be reinforced with variable cross-section according to the stress analysis results. According to the requirements in the "Reticulated She...
