Problems solved by technology

However, due to the weaker seismic capacity of the wall with round holes compared to the solid wall, and the horizontal direction of the structure is only connected by soft cable members, it lacks the anchorage of the structure in the vertical direction, especially the connection between the plate and the plate. Anchorage on nodes, which limits its domestic application due to weak seismic performance

Embodiment 1

[0044] Embodiment 1: Build a multi-storey tetrahedron prefabricated building, and the first floor of the prefabricated circular hole plate wall is all filled with grout.

[0045] A prefabricated round-hole slab wall seismic isolation structure with ribs inserted through it, including prefabricated concrete parts: a prefabricated round-hole slab wall A, a structural bottom plate B, a seismic-isolation floor E, and a standard floor F. Including machined parts: flexible cable connection device, thick steel plate C, vibration isolation support D and rib insertion positioning mold G. It also includes reinforcement materials processed according to length, where the long inserts include the long inserts of the bottom plate B1, the threaded inserts H and the ordinary inserts J, the short inserts include the short inserts of the bottom plate B2, the ordinary inserts E1 of the isolation floor, The threaded ribs E2 of the seismic floor slab, the short ribs are pre-embedded on the concret...

Embodiment 2

[0055] Embodiment 2: Build a multi-storey tetrahedron prefabricated building, and no grout is poured into the prefabricated circular hole plate wall on the first floor.

[0056] In Example 1, when installing the prefabricated circular hole panel wall A on the structural bottom plate B, no grout is poured into the circular hole A1 of the first floor panel wall. Because the bottom plate long rib B1 of the structural bottom plate B contains prestress, the compressive and shear strength of the prefabricated circular hole plate wall A on the first floor will be reduced, and the ductility will be increased. Others are the same as in Example 1.

[0057] In the above embodiments, since the first floor to the top floor are fixed with various ribs in the round holes of the board wall, a circle of thick steel plates is fixed on the top of the first layer, and from the round holes of the board walls above the second floor and each layer The joints of the prefabricated round-hole plate wal...

Abstract

The invention relates to a joint bar through type prefabricated circular hole plate wall seismic isolation structure. The structure is of a multi-layer assembly type structure and sequentially comprises a structural bottom plate, a vibration isolation layer floor slab and a plurality of standard layer floor slabs from bottom to top, wherein prefabricated circular hole plate walls serve as wall faces between the floor slabs, every two adjacent prefabricated circular hole plate walls are horizontally connected through a soft cable structure, slurry is poured between the two adjacent prefabricated circular hole plate walls, the upper prefabricated circular hole plate wall and the lower prefabricated circular hole plate wall are vertically connected through a through joint bar, slurry is poured between the upper prefabricated circular hole plate wall and the lower prefabricated circular hole plate wall, the upper portion of the joint bar is fixed through a positioning mold, the top of the first-layer wall is connected with a seismic isolation layer floor through thick steel plates and seismic isolation supports, and the thick steel plates are fixed in a closed mode, so that the integrity of the first-layer wall top horizontal components is enhanced. The novel structure system is light in weight, suitable for standardized production, convenient to transport, convenient and fast to assemble, good in shock insulation performance, firm in overall structure, low in cost, fast to construct and safe in structure.

Description

technical field [0001] The invention relates to a prefabricated building structure, in particular to a prefabricated round-hole plate wall shock-isolation structure with ribs inserted through. Background technique [0002] Prefabricated buildings have the characteristics of high efficiency, energy saving and environmental protection, so they have received extensive attention and use at home and abroad. The prefabricated round hole plate wall structure is a kind of prefabricated building, which has the advantages of light weight and fast assembly speed, and is widely used in Europe. However, due to the weaker seismic capacity of the wall with round holes compared to the solid wall, and the horizontal direction of the structure is only connected by soft cable members, it lacks the anchorage of the structure in the vertical direction, especially the connection between the plate and the plate. The anchorage on the node limits the domestic application due to its weak seismic per...
