Embodiment 1

[0045] Embodiment one: see figure 1 as shown,

[0046] A new type of prefabricated integral concrete shear wall panel with holes at the bottom and multi-connected beams, including the lateral connecting reinforcement 6 of the precast concrete shear wall panel, the top connecting reinforcement 5, and the bottom installation corresponding to the top connecting reinforcement 5 The sleeve 8, at least one row of window openings 2.1 in the middle of the wall panel, and the two sides of the window opening 2.1 respectively form the wall limb 1 of the shear wall panel, the upper side of the window opening 2.1, and the two adjacent wall limbs 1 The top end is connected to form a common connecting beam 3, which also includes:

[0047] The lower end of the wall panel is provided with a structural opening 2.2 corresponding to the window opening 2.1, and an energy-dissipating connecting beam A4 is formed between the structural opening 2.2 and the window opening 2.1.

[0048] The window op...

Embodiment 2

[0051] Embodiment two: see figure 2 As shown, the difference from the first embodiment is that the prefabricated concrete shear wall panel is a three-leg shear wall, and there are two rows of window openings 2.1 and structural openings 2.2.

Embodiment 3

[0052] Embodiment three: see image 3 As shown, the difference from Example 1 is that the precast concrete shear wall panel is a three-leg shear wall, and there is a door opening 2.3 on the wall foot 1, and the upper side of the door opening 2.3 is also a common connecting beam 3.

Abstract

A new type of prefabricated integrated concrete shear wall panel with holes at the bottom and multi-connected beams, including the lateral connection reinforcement of the prefabricated concrete shear wall panel, the top connection reinforcement and the bottom installation sleeve corresponding to the top connection reinforcement, There are window openings in the middle of the wall panels and structural openings corresponding to the window openings, wall piers, common connecting beams, energy-dissipating connecting beams A and energy-dissipating connecting beams B at the lower end of the wall panels. The openings have the same width, and the structural openings are filled with lightweight non-structural materials, and the top connecting reinforcement protrudes upwards from the wall pier to connect the upper and lower shear wall reinforcements. The invention reduces the number of steel bar connections, lightens its own weight, facilitates construction, transportation and hoisting, has good earthquake resistance, forms multiple anti-seismic defense lines in the building, and enhances the energy consumption capacity of the wall to achieve the purpose of reducing repair costs.

Description

technical field [0001] The invention belongs to the field of building components, in particular to a novel prefabricated integral concrete shear wall panel with holes at the bottom and multiple connecting beams. Background technique [0002] Traditional cast-in-place concrete shear wall panels can no longer meet the site's requirements for construction efficiency. With the development of construction technology, residential standardization is the premise of industrialization, the inevitable trend of residential construction development, and the key to promoting the healthy development of residential construction. It is also an inevitable trend and only way for the development of housing construction. The prefabricated shear wall structure is one of the main structural forms of industrialized housing, but the following problems still exist in the design and construction of prefabricated integral shear wall and frame shear wall structural systems: [0003] 1. Conventional pre...
