Description

Technical Field

[0001] The invention relates to the technical field of structural engineering, and in particular to an energy dissipation steel module and an assembly method thereof, and a building structure. Background Art

[0002] Modular construction is a modern construction method that prefabricates standardized building modules in a factory and then transports them to the site for assembly and installation. This method has many advantages over traditional on-site construction. For example, the modules can be prefabricated in a controlled environment to ensure quality consistency and construction speed; the overall construction period of the construction project is significantly shortened because the modules are produced and prepared both in the factory and on site; through mass production and standardized design, the material utilization rate is high and waste is reduced. At the same time, factory production reduces labor costs and construction time; construction waste is centrally processed, which makes it easier to recycle and reuse resources, and the on-site construction time is short, reducing interference with the surrounding environment; modular buildings can be customized according to needs to meet different functional and aesthetic requirements; building modules can be disassembled and reassembled to facilitate the expansion and transformation of buildings.

[0003] In construction projects, in order to improve the seismic performance of buildings, traditional methods usually adopt reinforced structures or use seismic supports. However, these methods often have problems such as complex construction, high cost, and difficult maintenance. Energy dissipation steel modules replace ceiling beams with energy dissipation beams to absorb and dissipate seismic energy. As a new type of seismic solution, they can effectively reduce the vibration response of buildings and protect the safety of structures. However, existing energy dissipation steel modules are complex in design, difficult to install, and lack standardized connection methods. Summary of the invention

When the lower end of the upper module column 2 is connected to the upper end of the lower module column 2, the flanges with U-shaped notches are connected, and the upper and lower U-shaped notches are connected to form a rectangular hole corresponding to the rectangular inspection hole 9 on the open hole connector located inside the module column 2.

[0041] The butterfly springs 4 at both ends of the separated energy dissipation beam 5 are respectively fixedly connected to the end plates 7 with bolt holes 3. A U-shaped notch is provided in the middle of the end plate 7. The notch size corresponds to the rectangular hole formed by the U-shaped notches on the flange when the upper and lower module columns 2 are vertically spliced ​​and the rectangular inspection hole 9 on the open hole connector. The U-shaped notch is vertically symmetrically and equidistantly arranged with 8 bolt holes 3. The number and positioning of the bolt holes 3 on the end plate 7 correspond one-to-one to the total number and positioning of the bolt holes 3 after the ends of the upper and lower module columns 2 connected thereto are butt-jointed, and high-strength bolts 6 are used for connection.

[0042] Integral energy dissipation steel module: The module column 2 is a square cross-section, and the flanges at both ends are connection surfaces 10, wherein one end fixedly connected to the two module beams 8 and the middle position of the two adjacent flange ends fixedly connected to the two module beams 8 are provided with a U-shaped notch, and a bolt hole 3 is arranged at equal distances on both sides of the U-shaped notch, for a total of 2 bolt holes 3, which are used to complete the bolt connection with the opening connector; 4 bolt holes 3 are arranged at the ends of the two flanges of the opposite sides as the connection surface 10 between the energy dissipation steel modules in the horizontal direction, which can also be used as the connection surface 10 with the opening connector and the vertical square The connection surface 10 between the energy dissipation steel modules depends on the splicing position of the energy dissipation steel modules; a U-shaped notch is opened in the middle of the two adjacent flange ends connected to the integral energy dissipation beam 1 and the open hole connector at the other end, and two bolt holes 3 are equidistantly arranged on both sides of the U-shaped notch, a total of four bolt holes 3, which are used to complete the bolt connection with the integral energy dissipation beam 1 and the open hole connector; four bolt holes 3 are arranged on the ends of the two flanges on the opposite side as the connection surface 10 with the open hole connector, the energy dissipation steel module in the vertical direction and the energy dissipation steel module in the horizontal direction.

[0043] As a key component for realizing the vertical connection of the integral energy dissipation steel module, the perforated connector has a rectangular cross-section and bolt holes 3 are arranged on all four wing plates.

In this embodiment, the perforated connectors can meet the strength, stiffness and ductility requirements according to the connection characteristics of the modular units; the energy dissipation module beams 8 can be selected from perforated steel plates, energy dissipation steel plates or dampers to achieve the energy dissipation capacity of the structure.

[0046] The bolt fixer is used to assist in bolt connection and complete the splicing between modules. The cross-sectional shape of the bolt fixer is the same as that of the perforated connector. The outer surface of the bolt fixer contacts the inner surface of the perforated connector. The bolt holes 3 on the bolt fixer correspond one-to-one with the bolt holes 3 on the perforated connector and the flanges at both ends of the module column 2. The bolt holes 3 on the bolt fixer are non-through holes, also called nut holes 13, which are used to fix the bolts to ensure that the bolt connection is tight and secure. The bolts pass through the bolt holes 3 inside the perforated connector, pass out from the bolt holes 3 of the wing plates at the end of the module column 2, and are fixed with nuts.

When splicing in the horizontal direction, the components to achieve the connection are the module column 2 and the separate energy dissipation beam. The two energy dissipation steel modules are symmetrical in the plane; the number of separate energy dissipation steel modules involved in the splicing is two. When splicing in the vertical direction, the components to achieve the connection are the module column 2, the separate energy dissipation beam 5, and the perforated connector. The two energy dissipation steel modules are symmetrically distributed up and down.

[0048] In this embodiment, during splicing, the connections between the module columns 2 of different energy dissipation steel modules, between the module columns 2 and the opening connectors, and between the module columns 2 and the separated energy dissipation beams 5 are achieved by high-strength bolts.

The upper energy dissipation steel module module column 2 has a U-shaped notch flange with two bolt holes 3, which is docked with the U-shaped notch flange with six bolt holes 3 of the module column 2 of the lower energy dissipation steel module. The butt joint forms eight equidistant bolt holes 3, which are aligned with the eight bolt holes 3 on the end plate 7 and the eight bolt holes 3 on the internal open hole connector. The U-shaped notches are docked to form a rectangular hole, which is aligned with the inspection hole 9 on the internal open hole connector.
