Problems solved by technology

[0004] However, there are still some deficiencies in the prefabricated composite steel plate shear wall structure in actual engineering: concrete is a quasi-brittle material, which has poor co-deformation ability with steel plates, and the concrete slab is prone to damage and spalling under the action of earthquakes
The damaged concrete slab has weak rest

Example Embodiment

[0024]The present invention will be further described in detail below with reference to the accompanying drawings.

[0025]The construction process of the assembled ECC-steel plate combination consumption shear wall includes the following steps:

[0026](1) Preparation of steel columns, steel beams and ECC-steel plate combined with steel columns, steel beams and ECC-steel plates in the factory:

[0027]According to the design requirements, a certain number of vertical vertical sections are opened, and the respective levels and vertical opening plate connectors are welded. The ECC board uses two-way ribs, and the steel bar passes through the reserved hole of the opening plate connector, and is positioned. The special template is used to pour ECC, so that the ECC board reserves a gap between the edge position and the thickness, and inserts the angle steel. The embedded steel sheet and the ECC board reserve a certain number of bolt holes in the respective position.

[0028](2) Construction site as...

Abstract

The invention discloses a fabricated ECC-steel plate combined energy dissipation shear wall. The fabricated ECC-steel plate combined energy dissipation shear wall comprises an embedded steel plate, perforated plate connecting pieces, an outer pouring ECC plate and an edge frame; a vertical seam is formed in the embedded steel plate, and the perforated plate connecting pieces are welded on the embedded steel plate; the ECC plate is bidirectionally provided with reinforcements, and the reinforcements penetrate through holes of the connecting pieces; the combined energy dissipation shear wall is in bolt splicing with the edge frame through angle steel. According to the fabricated ECC-steel plate combined energy dissipation shear wall, as a main lateral force resistant component of a structure, shear bearing capacity is high, resistant-lateral rigidity is high and ductility is good, a concept of multiple anti-seismic defense lines is achieved, and the advantages of being high in durability and good in fire resistance are possessed; meanwhile, massive wet operation on a construction site can be avoided, and construction is convenient and fast.

Description

technical field [0001] The invention relates to the technical field of building structure engineering, in particular to an assembled ECC-steel plate composite energy-dissipating shear wall. Background technique [0002] Compared with the traditional cast-in-place structure, the prefabricated building adopts "factory production of components and assembly operation of construction", which has the advantages of controllable quality, convenient construction, energy saving and emission reduction. Among them, the prefabricated steel structure has a high degree of industrialization, light weight, strong plastic deformation ability, and excellent seismic performance, which is in line with the development direction of my country's construction industrialization. [0003] When the number of building floors exceeds 20, the traditional steel frame needs a larger beam-column section to control the lateral movement of the structure, which is less economical. Steel plate shear wall, as a ...
