Multidimensional space steel structure installation joint positioning construction method

Abstract

Provided is a multidimensional space steel structure installation joint positioning construction method. A tester is adopted for detecting the boundary dimension of an entity joint, dynamic fitting comparison is continuously performed between a joint design model with the assigned end face and the boundary dimension of the entity joint, the entity joint is continuously corrected and positioned further, the method is mainly applicable to accurate measurement positioning of complex variable space structure large multi-branch joints without operating control points, multi-direction adjustment positioning can be achieved, and installation precision can be conveniently controlled. The method has wide applicability, operation is easy and convenient, the safe connection requirement in a joint area can be met, lots of construction plant, manpower and mechanism input is reduced, manpower, instrument equipment and man hours needed for completing the construction measurement control process are little, labor productivity is improved and construction quality is guaranteed.

Description

technical field [0001] The invention relates to an on-site construction method and equipment technology of international patent classification E04G building materials or building components, especially a multi-dimensional space steel structure installation node positioning construction method. Background technique [0002] In order to meet the requirements of beautiful, complex and personalized buildings, buildings with complex and variable space special-shaped steel structures are becoming more and more common. The new steel structure forms are usually completed by multiple branch nodes and folded plate steel frames on the space surface Complex shape, but the space hoisting workload of this type of steel member is cumbersome, and it is difficult to effectively control the installation accuracy by conventional methods. [0003] Steel structure engineering is composed of steel beams, steel columns, steel trusses and other components made of section steel and steel plates; the...

Problems solved by technology

(2) The seriousness of construction quality problems of steel structure engineering projects is manifested in: generally, affecting the smooth progress of construction, causing delays in the construction period, increasing costs, and seriously, building collapses, causing personal casualties, property damage, and causing unhealthy social influences

(3) The quality problems of steel structure engineering construction will continue to develop and change with the external changes and the extension of time, and the quality defects will gradually reflect

Another example is that the component is subjected to overload for a long time, and the steel component will undergo arching deformation, which will cause hidden dangers.

(4) Since the existing buildings are mainly made of concrete structures, the management personnel and technical personnel engaged in construction are relatively unfamiliar with the production and construction techniques of steel structures, and the specific construction personnel do not understand the installation and positioning of nodes in steel structure engineering Scientific construction methods lead to frequent accidents in the construction process

Existing relevant improved technologies are rarely made public
