Embodiment 1

[0017] 1.1. The project of Guizhou Provincial Outdoor Sports Comprehensive Training Center is undertaken by Guizhou Construction Engineering Group No. 4 Construction Engineering Co., Ltd. The roof of this project adopts a grid structure, and the concrete structure type is a frame structure. There are 4 floors above the ground and 1 floor underground. The cornice elevation is 23.9m. The roof projection area of ​​the training hall is about 2344.5m 2 . The area where it is located is a non-seismic area, the seismic fortification intensity is 6 degrees, and the design service life is 50 years. The concrete strength grades are all C30, and the concrete strength grades of the main structure all meet the design requirements.

[0018] 1.2. Introduction to grid design

[0019] 1.2.1. The roofing project of the training hall is composed of two parts: A~E area roof grid frame and F~N area roof grid frame. The shape of the grid frame is irregular, and its axis dimension is 33.6x41.0m;...

Abstract

The invention discloses a net rack mounting construction method. The net rack mounting construction method comprises the following technological processes that a net rack supporting point is measuredand positioned; a raw material is rechecked; a basic net rack striding lower chord bolt ball and a lower chord are mounted; a basic net rack striding upper chord bolt ball, an upper chord and a web rod are mounted; basic net rack striding lifting is carried out; basic net rack striding in place and support connecting are carried out; the rest of the net rack is mounted in bulk in high altitude; oil paint is repaired; and acceptance inspection is carried out. According to the construction method, the problems that the side around a construction plant is narrow, and consequently a car is hard tomount and hoist can be overcome, net rack mounting construction is completed in limited space, and the method is efficient, safe and worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a grid installation and construction method. Background technique [0002] The roof of the existing outdoor sports comprehensive training hall project usually adopts a grid structure, and the grid is connected by bolt balls. , the basic cross-grid is assembled on the floor. After the assembly is completed, the grid is lifted to the top of the column with an inverted chain and placed in place. After the grid is in place, the grid support is fixed, and then the installed grid is used as the installation platform. The rest of the network frame is installed; the network frame support is located on the top of the column and the ring beam of the civil structure, and the height of the network frame body is shown in the section diagram of the network frame. Steel structural components are coated with water-based inorganic zinc-rich primer, epoxy miracite intermediate paint...
