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

The invention discloses a precast assembled integrated type concrete shear wall panel with a bottom hole containing multiple coupling beams. The precast assembled integrated type concrete shear wall panel comprises lateral connection rebars of the precast concrete shear wall panel, top connection rebars and bottom installation sleeves corresponding to the top connection rebars. The middle of the wall panel is provided with window holes. The lower end of the wall panel is provided with structure holes corresponding to the window holes, wall limbs, a general coupling beam, energy consumption coupling beams A and energy consumption coupling beams B. The width of the window holes is the same as that of the structure holes. The structure holes are filled with light non-structural materials. The portions, on the wall limbs, of the top coupling rebars are stretched out upwards to connect upper layers of shear wall rebars and lower layers of shear wall rebars. By means of the precast assembled integrated type concrete shear wall panel, the number of connected rebars is reduced, self weight is reduced, construction transportation and hoisting are facilitated, the concrete shear wall panel is good in anti-seismic performance, multiple seismic fortification lines are formed for a building, the energy-dissipation capacity of a wall body is enhanced, and the purpose of reducing repair cost is achieved.

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...
