Embodiment Construction

[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0018] Such as figure 1 As shown, the construction method of the present invention will be described in detail below by taking an overhaul hangar engineering hangar of an international airport as an example. Daylighting strips.

[0019] Adopt grid structure hoisting and roof enclosure construction method of the present invention to carry out construction, comprise the following steps:

[0020] (1) According to the conventional construction process, carry out the overall assembly construction of the steel structure grid and truss on the ground; after all the rods and spheres are welded, carry out corresponding inspection and acceptance.

[0021] (2) After the acceptance is completed, the main and secondary purlins of the roof enclosure will be installed, and the bottom plate of the roof will be rolled in the factory. When the secondary purlins are installed,...

Abstract

The invention discloses a method for hoisting a net rack structure and constructing a roofing enclosure, comprising the following steps: (1) carrying out the integral ground splicing construction of a steel structural net rack and a steel structural truss according to the conventional construction process; (2) installing a main purlin and a secondary purlin of the roofing enclosure; (3) paving roofing bottom-layer profiling steel plates on positions except for a reserved ventilation opening and a base plate at a side span position; (4) integrally hoisting the steel structural net rack and the steel structural truss, and then installing and fixing the same; and (5) paving the roofing bottom-layer profiling steel plates on the reserved ventilation opening and the side span position. The invention only needs to install safe separation nets, protective barriers and lifelines in areas of the bottom and the circumference of a roofing daylighting band, which are not paved with the roofing base plates; and in addition, compared with an original construction process which needs to fully install the safe separation nets, the protective barriers and the lifelines under a steel structure, the invention greatly saves the input amount of safety protection facilities.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a grid structure hoisting and roof enclosure construction method. Background technique [0002] Grid structure is a structural form with a wide range of applications. It can be used in public buildings such as gymnasiums, clubs, exhibition halls, theaters, station waiting halls, etc. In recent years, it has also been increasingly used in warehouses, hangars, factories, etc. In industrial buildings. [0003] The grid structure is a high-order hyperstatically indeterminate space structure composed of many rods according to certain rules. It changes the stress system of general plane trusses and can bear loads from all directions. Due to the mutual support between the rods, the spatial rigidity is large, the integrity is good, the earthquake resistance is strong, and it can withstand the adverse effects caused by the uneven settlement of the foundation; e...
