Installation structure of plant roof grid structure project and construction method thereof

Abstract

The invention discloses an installation structure of a plant grid structure project, and belongs to the technical field of building construction. The installation structure comprises a roof frame beam, wherein a roof panel layer is arranged in the roof frame beam, and at least two grid structures are connected to the roof panel layer; the grid structures comprise grid structure upper chord layersand grid structure lower chord layers, wherein upper chord grid structure balls and lower chord grid structure balls are arranged on grid nodes of the grid structure upper chord layers and the grid structure lower chord layers correspondingly; the upper chord grid structure balls and the lower chord grid structure balls are arranged in a staggered mode, and grid structure web members are assembledand connected between the upper chord grid structure balls and the lower chord grid structure balls; a plurality of main purlins are arranged in parallel above the grid structure upper chord layers,a plurality of secondary purlins perpendicular to the main purlins are assembled above the main purlins, and the secondary purlins are connected with the roof panel layer; and the roof frame beam is prefabricated with a plurality of L-shaped reinforced concrete columns, and the two arms of the reinforced concrete columns are correspondingly assembled and connected with the corresponding lower chord grid structure balls so as to achieve the purpose of improving the roof grid structure to improve the water leakage prevention effect and structural strength and simplifying and standardizing the construction process.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to an installation structure and a construction method of a roof network frame engineering of a factory building. Background technique [0002] Nowadays, many industrial buildings and many public buildings have higher and higher requirements for large spans and large spaces, so most of the roof structures are designed as steel structure roof panel grid structures. The steel structure roof grid structure of the factory building in the prior art adopts the supporting grid (network frame, steel roof truss) as the roof support structure, and uses materials such as single-layer pressed tile roof or EPS composite tile roof as the roof body structure. [0003] At present, the existing roof grid structure mainly has the following defects during use: [0004] (1) The joints of single-layer tile roofs and EPS composite board roofs are simply overlapped, and their in...

AI Technical Summary

Problems solved by technology

[0004] (1) Since the seams of single-layer tile roofs and EPS composite board roofs are simply overlapped, their internal structure design is unreasonable. Therefore, in actual use, the waterproof and sealing effects of the overlapping points of multiple roofs are very poor. It is prone to problems such as rain leakage;

[0005] (2) The connection point between the roof body and the wall is also due to the different material properties, and the structural rigidity of the connection is also different. The ability to withstand structural deformation is poor, and it is easy to cause damage to the connection, resulting in problems such as collapse of the factory building during use. Affect normal use;

[0006] (3) In the roof grid structure, the support and the purlin are connected by screws, which cannot control the deformation of thermal expansion and contraction

[0010] (3) The use efficiency of construction machinery cannot be improved, and it is necessary to continuously move equipment to meet the installation progress requirements of roof panels;

[0011] (4) The occupation of the construction site is large, which affects the construction progress of other surrounding projects;

[0012] (5) It is difficult to manage and coordinate, and the workload of organizing construction personnel, materials, and machinery is huge, and at the same time, the safe production of construction cannot be effectively guaranteed
