Embodiment Construction

[0014] In order to further understand the invention content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:

[0015] figure 1 It is the plan view of the floor structure of a multi-storey public building. When the height of the regular hexagon is 2h=2×2m=4m, its span L y =6×2h=24m, the column network on the long side is arranged alternately with b and 2b, L x =17b=17×2m / sin60°=17×2.31m=39.27m, the floor area of ​​each floor is 943m 2 , the total area of ​​the four-story hall is 3770m 2 (Stairs, elevators, and fire protection area are not included in the lobby), and the structure of the entire lobby building is "multi-layer (4 floors) large-span (L=24m) assembled integral space steel grid box structure".

[0016] The specific construction and installation method is carried out as follows:

[0017] Step 1: Press figure 1 Plane and level the ground ...

Abstract

The invention relates to a manufacturing method for regular hexagonal honeycomb latticed steel hollow floor frame box type structure. The manufacturing method is characterized by comprising the following steps of blanking, welding and processing a component (a), a component (b) and a component (c) in a factory workshop, transporting the component (a), the component (b) and the component (c) to a construction site, assembling the component (a), the component (b) and the component (c) into a floor frame unit (A), a floor frame unit (B) and a floor frame unit (C), connecting the floor frame unit (A) and the floor frame unit (B) and the floor frame unit (C) via high-strength bolts to form a regular hexagonal honeycomb steel plane grid and placing the grid on a floor height marked position via a supporting wall rack. A reinforced bar concrete three-dimensional grid regular hexagonal prefabricating plate is installed on the supported regular hexagonal honeycomb steel plane grid; pin holes are formed in the regular hexagonal honeycomb steel plane grid; reinforcing bars are tied thereon; concrete is cast on a template formed by the regular hexagonal prefabricating plate; the template is maintained. The manufacturing method for the regular hexagonal honeycomb latticed steel hollow floor frame box type structure, steel components are can all blanked and manufactured in the factory and transportation and construction can be facilitated.

Description

technical field [0001] The invention belongs to the technical field of building steel structures, and in particular relates to a method for manufacturing a regular hexagonal honeycomb mesh steel hollow floor box structure. Background technique [0002] In the traditional conventional structural system, if a multi-storey long-span building is built, the amount of steel used will increase significantly. In order to save construction costs, the investor chose a large-span single-story industrial Factory buildings sprang up everywhere, and long-span public and industrial buildings were limited to a single floor. With the increase of land purchase system costs and the promulgation of related land resource saving policies, in 2007, the spatial grid box structure was proposed. It has replaced the traditional steel frame and portal frame system in the field of long-span public and industrial buildings for a long time. At the same time, with the emergence of "a new system of assemb...
