Problems solved by technology

[0003] However, for complex tubular space-shaped structures, the structure is complex and the space structure is shaped, such as spherical, spiral, twisted, etc., it is difficult to locate the nodes during processing, and the positioning points are not in the same plane. There is no uniform positioning reference for the angle, and the normal sequence of production will easily cause component misalignment, orientation deviation, and installation failure, resulting in rework, rework, waste of manpower and material resources, and delays in the construction period.

Embodiment Construction

[0013] In order to describe the technical content, structural features, and achieved effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

[0014] Such as figure 1 As shown, the pre-installation method of the spherical space structure 100 of the present invention is suitable for building a spherical building, and the spherical building is a spherical space structure 100. Specifically, the spherical space structure 100 includes a dome 1, a skeleton 2 and a horizontal tube 3. The dome 1 is located at the inner top, the skeleton 2 is in an arc shape, and the skeleton 2 and the horizontal tube 3 are arranged along the spherical surface in a staggered manner, so as to form a spherical shape.

[0015] see figure 2 and image 3 , the pre-installation method of the spherical space structure 100 includes the following steps:

[0016] In step S1, the spherical space structure 100 is simul...

Abstract

The invention discloses a preassembly method for a spherical space structure. The preassembly method comprises the following steps that the spherical space structure is divided into a plurality of sections of frameworks and cross pipes which need to be welded in a simulation mode; a space coordinates system is set according to a vertical sphere center axis ground point, strut coordinates, dome coordinates and vertical leg coordinates are arranged on the intersection points of frameworks and the cross pipes correspondingly, the dome coordinates are located on the sphere center axis, and the vertical leg coordinates are located on the circumference of the ground; according to the strut coordinates, the dome coordinates and the vertical leg coordinates, struts, a middle jacking column and vertical legs are arranged on the ground, and a dome is fixed to the top end of the middle jacking column; the frameworks are arranged at the top ends of the struts, and the frameworks are welded fixedly, the frameworks and the dome are welded fixedly, and the frameworks and the vertical legs are welded fixedly; and the cross pipes are welded to the frameworks. The preassembly method for the spherical space structure has the advantages that construction is simple and convenient, structure locating is accurate, errors and reworking are avoided effectively, and construction efficiency is high.

Description

technical field [0001] The invention relates to a processing and manufacturing method for a special-shaped structure roof, in particular to a method for preassembling a spherical space structure. Background technique [0002] In ordinary construction projects, steel beams are often used to build roofs. For ordinary and small flat roofs, due to the regular shape and the same shape of the steel beams used, there are many construction methods , for example: one of them is to form an integral roof by welding each steel beam on the ground, and then lift the entire roof structure to the top of the house with a crane and fix it; the other is to use bolts to connect and divide into multiple Each module is manufactured in a single piece in the manufacturing workshop, and the overall structure is pre-assembled. After the pre-assembled structure has no problems, it is welded and fixed to complete the production of the components; When the goods are delivered to the site for installati...
