Description

Technical Field

[0001] The utility model belongs to the technical field of steel structure construction equipment, and particularly relates to an assembled support for a steel structure reticulated shell structure. Background Technique

[0002] Steel structure single-layer reticulated shell structures are widely used in modern large-span cover main structures due to their good spatial structure and visual effects. As an important node of the steel structure single-layer reticulated shell structure, the support structure bears the vertical and horizontal loads and bending effects of many sub-structure types such as the reticulated shell steel structure main body, mechanical and electrical, and decoration. The structural design of the support structure and the close cooperation of on-site construction are particularly important.

[0003] As an important stress point of the steel structure single-layer reticulated shell structure, the support node of the steel structure single-layer reticulated shell structure has extremely high requirements for structural design and construction quality control. As one of the important types of support structures, the internal complex stiffening plate structure of the rigid connection node can meet the structural strength verification; however, during the on-site implementation process, its internal hidden welds are often difficult to weld, or the welding quality is difficult to control due to factors such as narrow welding operation space. For the support node of the traditional steel structure single-layer reticulated shell structure, the manufacturing difficulty of the support node will increase due to the difficulty of welding the internal hidden welds, or the welding quality will be reduced due to factors such as narrow welding operation space, thereby reducing the safety performance of the support structure.

[0004] The support nodes of the traditional steel structure single-layer reticulated shell structure have always had the following disadvantages:

[0005] 1. The support node of the traditional steel structure single-layer reticulated shell structure is an integral support node, and the adjustable margin for on-site installation and positioning is poor.

[0006] 2. The structure of the support node of the traditional steel structure single-layer reticulated shell structure is complex, and the processing and manufacturing cycle is long.

[0007] 3. The welding of the hidden welds of the support node of the traditional steel structure single-layer reticulated shell structure is difficult, and the welding quality is not easy to control.

[0008] Therefore, as the first construction step of the steel structure reticulated shell main structure construction, how to disassemble the process and structure to make the support structure meet both the structural design requirements and the on-site rapid implementation and quality control requirements on the premise of meeting the design requirements of strength and stiffness of the support structure is a technical problem to be solved urgently.

[0073] An assembled support for a steel structure reticulated shell structure of the utility model is mainly composed of Component One and Component Two. Component One is the cross stiffening steel plate inside the support, and Component Two is a steel sleeve structure with the same specification as the reticulated shell member and welded to the cross stiffening. The cross stiffening and the steel sleeve with a weld are welded into a whole to form a complete support structure.

[0074] The utility model Figure 1This is a schematic diagram of the assembled support structure of the steel structure reticulated shell of the present utility model. The red part in the figure is the position where the groove is opened.

[0077] For an assembled support of the steel structure reticulated shell of the present utility model, the steel sleeve structure is fitted with the cross stiffening steel plate through 4 opened slots, and then through the grooves opened on the 4 slots, the external steel sleeve structure and the cross stiffening steel plate are penetration welded to form the overall support.
