Embodiment 1

[0031] Embodiment 1: This embodiment aims to provide a prefabricated truss beam steel beam tube structure system that adopts full bolt connection, which is mainly used for prefabricated truss structures. For existing equipment, bolt welding connections are mostly used, and the overall assembly has a low degree of disassembly , some parts are damaged and cannot be replaced, and the overall assembly and transportation costs are high, and construction is difficult. Based on this, this embodiment provides an assembled truss beam steel beam tube structure system that adopts full bolt connections.

[0032] Such as figure 1 As shown in , a prefabricated truss girder steel beam tube structure system using full bolt connection, including truss beam unit 4, column unit and node unit; The node units are connected with the column units, and the column units are distributed on the periphery and are at the same elevation.

[0033] In a specific implementation, the truss beam unit 4 include...

Embodiment 2

[0042] Embodiment 2: This embodiment is basically the same as Embodiment 1, and the difference is that this embodiment further explains the structure of the connecting column 2 .

[0043] In this embodiment, the connecting column 2 includes an upper connecting column 21 and a lower connecting column 22 that can be butt-connected together, wherein the upper end of the upper connecting column 21 is provided with a connecting plate 23, and its lower end is provided with a docking plate 24. The lower end is provided with a connecting plate, and the upper end is provided with a butt plate 24, and the two butt plates are adapted and provided with corresponding through holes.

[0044] In this embodiment, the connecting column is a detachable structure. During the specific construction, the upper connecting column 21 and the lower connecting column 22 are respectively connected with the side node column 1, and the truss beam unit is assembled and connected with the middle node column, ...

Embodiment 3

[0046] Embodiment 3: This embodiment is basically the same as Embodiment 1, the difference is that in this embodiment, there are too many connecting bolts between the upper connecting column and the lower connecting column, and most of them are in the high-altitude operation state, so the construction is difficult and the work For the problem of large quantity, the present embodiment sets up a bolt fixing frame and a nut fixing frame to reduce the problem of difficult bolt construction in the process of working at heights.

[0047] In the specific structure, the present embodiment is provided with a bolt fixing frame 5 on the upper connecting column, and the bolt fixing frame 5 includes an upper fixing sleeve 51, a top screw 52 and a connecting bolt 53; the upper fixing sleeve 51 is matched and set on the upper connecting column 21 , its side is provided with the top wire 52 that runs through its side wall, the position of the upper fixed sleeve 21 can be fixed by the top wire ...

Abstract

The invention discloses a fabricated truss girder steel beam tube structure system adopting full bolt connection. The fabricated truss girder steel beam tube structure system comprises truss girder units, stand column units and node units. Each truss girder unit comprises an upper chord member, a lower chord member and web members; the upper chord member and the lower chord member are connected together through the web members, and corresponding mounting holes are formed in the two ends of the upper chord member and the lower chord member; each node unit comprises middle node columns and middle node plates; the middle node plates are fixed at the upper and lower ends of the middle node column; each stand column unit comprises connecting columns and side node columns which are alternately arranged. The truss girder units are connected between the side node columns or between the side node columns and the middle node columns to form a truss layer. Side node plates are arranged at the upper end and the lower end of a side node column, the connecting plates are arranged at the upper end and the lower end of a connecting column, and the connecting plates are matched with the side node plates. According to the fabricated truss girder steel beam tube structure system adopting full bolt connection, the fabricated truss girder steel beam tube structure system adopting full bolt connection can be combined and assembled through full bolts, factory customization and modular construction are facilitated, on-site assembling is easy, the structure is convenient to disassemble, recycle and combine and assemble, and the fabricated truss girder steel beam tube structure system adopting full bolt connection can be repeatedly used.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, and in particular relates to an assembled truss beam steel bundle tube structure system which adopts full bolt connection. Background technique [0002] At present, prefabricated steel structures are mainly connected by bolt welding, but welding naturally has some defects, such as: not being environmentally friendly enough, causing great harm to construction personnel; welds are prone to corrosion, and the quality is not easy to control; it is not conducive to the further improvement of the assembly rate. Raise and so on. Therefore, when possible, it is recommended to use bolts for the connection of fabricated steel structures. The small beam-column section has better mechanical properties, which can make the space utilization rate of the building higher, but it is accompanied by the difficulty of transportation and construction of the long-span steel structure. [0003] At the same t...
