Problems solved by technology

At present, the construction process of the skylight structure is mostly to stake out, cut and weld each component (especially the skeleton) at the installation site. The construction is difficult and it is difficult to ensure the installation accuracy, especially for the skylight of large buildings. Its components are bulky, and it is more difficult to accurately locate them in the air, so it is more difficult to ensure the accuracy requirements of their construction, and even some installation parts are difficult to pass the acceptance and have to be repeated construction

Embodiment Construction

[0046] First, the general idea of ​​the construction method of the present invention is introduced.

[0047] The main skeleton steel structure is special-shaped square steel pipe or square steel pipe, the wall thickness is mostly 6 and 14mm, and the thickest is 24mm; square steel or rectangular purlins are arranged in parallel and equidistant to the bottom edge of each surface. All structural connections are welded joints.

[0048] 1. Construction procedure: according to figure 1 Carry out construction according to the construction procedure shown.

[0049] 2. Countermeasures for engineering difficulties

[0050] 1. Accurate modeling, accurate lofting and cutting, to ensure the accuracy of component manufacturing

[0051] Use AutoCAD to accurately establish the space model of the main frame and purlins, accurately reflect the space angle and size of the component on each surface of the component, correctly draw the production size and cutting angle of each surface of the co...

Abstract

The invention provides a method for installing an overhead steel structure high, which belongs to a method for constructing a fixed structure. The prior installation method has defects that precise positioning is hard to realize and installation precision is hard to guarantee. The method comprises the following steps of: accurately modeling and correctly lofting and cutting, correctly paying off and accurately positioning; installing embedded parts, a temporary assembly jig and an upright post according to the paying-off position; positioning and fixing a joint on the temporary assembly jig; orderly lifting a main girder, a secondary girder and a purline; and unloading and dismounting the temporary assembly jig. The method is easy to guarantee manufacture precision of each component and installation precisions of the embedded parts, the temporary assembly jig, and the joint; the on-site lofting and cutting is unnecessary to undergo, and the on-site lifting and connection (welding) of each component are convenient.

Description

technical field [0001] The invention belongs to a construction method for fixing a building, in particular to a high-altitude installation method for a steel structure of a daylighting roof of a fixing building. Background technique [0002] The general skylight structure is formed by erecting a skeleton on the top of the building (such as standing on a concrete floor), and then installing purlins and glass curtain walls on the skeleton. At present, the construction process of the skylight structure is mostly to stake out, cut and weld each component (especially the skeleton) at the installation site. The construction is difficult and it is difficult to ensure the installation accuracy, especially for the skylight of large buildings. Its components are bulky, and it is more difficult to accurately locate them in the air, so it is more difficult to ensure the accuracy requirements of their construction, and even some installation parts are difficult to pass the acceptance and...
