Embodiment 1

[0062] refer to Figure 1 to Figure 8 , this series of drawings, for certain reasons, such as the clear expression of engineering views, individual details in the drawings have been omitted, the omission is based on the requirement of clear expression, and the omission will not affect professional Skilled persons should be allowed to reproduce this embodiment. To take a step back, due to the differences in the understanding ability of technicians, even if there are things that are not easy to understand, please bear with us.

[0063] exist figure 1 In , an example of a node is given, figure 2 , in order to give a detailed example of the internal combination state of the node, an example is given in this figure by partial dissection and partial omission. In this example, the missing part does not exist in reality, just A way to express the internal structure is just an example, please give me a correct understanding.

[0064] image 3 In , it is given in a top view state,...

Embodiment 2

[0087] refer to Figure 10 , in this embodiment, the innovation lies in the setting of the plastic weak zone on the steel beam. In this embodiment, the steel beam is divided into two groups, and the strength of the plastic weak zone 005 in each group is different and arranged at intervals. That is to say, some plastic weak areas have better plasticity, and some have poorer plasticity. When a strong earthquake occurs, the steel beams in the plastic weak areas can be deformed according to the set order, and the seismic performance of the building can be improved.

Embodiment 3

[0089] As a supplementary description to Embodiment 1, in fact, in the present invention, the number of steel beams corresponding to each group of connection plate assemblies can be six groups in Embodiment 1, or other numbers, such as 8 groups, 12 groups etc. Usually, the number is greater than 3, that is to say, it is used to complete the connection of more than three sets of steel beams. Of course, multiple or multiple groups of steel beams are evenly arranged in the circumferential direction of the connection plate assembly and arranged along the direction.

Abstract

The invention discloses a fabricated building large roof anti-seismic joint, a steel structure roof system and a construction method of the steel structure roof system. The steel structure roof system comprises vertical columns, beam components and connecting discs, pin hole channels are formed in steel sleeves at the ends of the beam components, and bolt holes are formed in flanges of the beam components; three or more sets of mounting holes are evenly formed in the connecting discs in the circumferential direction, and each set of mounting holes is provided with a circular hole and one or more pairs of arc-shaped long strip holes, wherein the circular holes and the pin hole channels are connected through steel pins; and the long strip holes and the bolt holes are fastened through high-strength bolts, after fastening, the beam components are eccentrically arranged in the tangent direction from the connecting discs, and under driving of high external force factors, the beam components have the rotating tendency relative to the circular holes. The connecting discs and the steel beams are connected in semi-rigid and semi-flexible modes, a proper center supporting column is matched according to the need for auxiliary supporting, and the requirements of a large-span and anti-seismic steel structure system can be met.

Description

technical field [0001] The invention relates to the technical field of prefabricated buildings, especially a large-scale roof seismic node, roof system and construction method of a prefabricated building, such as a large-scale steel structure. Background technique [0002] Architectural structural engineering is often used as the roof of various large public buildings, such as stadiums, exhibition halls, airports, etc. In the prior art, the building structure engineering is a metal plate node structure. [0003] The following examples are several styles of plate joint structure: [0004] CN 207597585 U discloses a web-reinforced aluminum alloy plate-type node structure, including a node plate assembly, a rod assembly, a reinforcement assembly and a fastening assembly, and the node plate assembly includes a top node plate and a bottom node plate spaced apart in parallel, The rod assembly includes a plurality of rods arranged around the central axis of the node structure, wh...
