Description

A kind of construction method of space grid structure engineering

Technical field

The present invention relates to the realm of building construction, it is more particularly related to which a kind of space grid structure engineering is applied Work method.

Background technique

With the development of the social economy, people are increasing to activity space demand, space grid structure application is also more next Wider, the development of technology is also higher and higher therewith, requires also to be increasingly stringenter to construction and Supervision Technology.

The space structure that grid structure is linked according to certain grid configuration by node by plurality of rods part.With sky Between the advantages that stress is small, light-weight, rigidity is big, anti-seismic performance is good;It can be used as gymnasium, cinema, show room, Waiting Lounge, body Educate the roof system of the buildings such as a grandstand canopy, hangar, two-way Large Column Spacing workshop.

But existing space net rack construction method is excessively cumbersome, due to great deal of nodes and rod piece during being constructed Presence so that speed of application is low, the occupancy of structure space is also big, influences the normal progress of engineering.

Summary of the invention

In order to overcome the drawbacks described above of the prior art, the embodiment of the present invention provides a kind of applying for space grid structure engineering Work method, construction method is regular, and great deal of nodes is identical with shape, the size of rod piece, and the method utilized in installation is identical, Easy to produce, product quality is high, and on-site consolidation is easy, and speed of application can be improved, structure occupied space is smaller, can more efficiently use Space can greatly increase the spatial stability of entire rack system using this installation method.

To achieve the above object, the invention provides the following technical scheme: a kind of construction method of space grid structure engineering, Specifically comprise the following steps:
