Embodiment 1

[0081] Embodiment one sees figure 1 with Figure 4 As shown, a self-supporting prefabricated concrete wall panel includes a panel body 10, and the shape of the panel body can be I-shaped, L-shaped or T-shaped. In this embodiment, it is a font.

[0082] The slab body includes a prefabricated part 1, the prefabricated part includes a prefabricated vertical reinforcement 11, a prefabricated horizontal reinforcement 12 and a prefabricated concrete 13, the vertical connection end of the prefabricated part has a vertical connector, the vertical The vertical connectors include the vertical steel bars 11 of the prefabricated part protruding from the edge face of the prefabricated part and more than two vertical shear connectors 3 . In this embodiment, four vertical shear connectors are arranged symmetrically on the left and right, and symmetrically on the top and bottom.

[0083] The vertical steel bars 11 of the prefabricated part protrude from one side of the edge end face of the...

Embodiment 2

[0090] Embodiment two see figure 2 with Figure 4 As shown, the difference from the first embodiment is that the vertical shear connector 3 is a steel piece arranged along the vertical length of the prefabricated part 1 .

Embodiment 3

[0091] Embodiment three see image 3 with Figure 4 As shown, the difference from the second embodiment is that the horizontal sides of the prefabricated part 1 have horizontal connectors, and the horizontal connectors include two symmetrical horizontal shear connectors 4 protruding from the edge end faces of the prefabricated part. The horizontal shear connector 4 is partially pre-buried in the prefabricated part, and the pre-embedded part is wrapped by the vertical reinforcement 11 of the prefabricated part and the horizontal reinforcement 12 of the prefabricated part. The horizontal shear connector 4 is an additional horizontal steel bar, steel plate, section steel or welded steel member.

Abstract

The invention relates to an inner-casting reinforced precast wall panel, a concrete wall, a structure system and a construction method. The wall panel comprises a precast part, wherein the precast part comprises precast part vertical reinforcing steel bars, precast part horizontal reinforcing steel bars and precast part concretes; vertical connecting pieces are arranged at the vertical connectingends of the precast part; vertical shear connectors are partially embedded into the precast part; at least one concrete inner-casting hole passage is arranged at the position, between the vertical connecting pieces, in the precast part; and the concrete inner-casting hole passages are continuously arranged along the vertical direction of the precast part. According to the inner-casting reinforcedprecast wall panel, the concrete wall, the structure system and the construction method provided by the invention, the concrete inner-casting hole passages are arranged, and at least one hole passageis located between the vertical shear connectors, so that the concretes between the vertical shear connectors are ensured to be poured densely, the concrete pouring quality between the vertical shearconnectors at a horizontal connecting area of the precast concrete wall panel is effectively improved, and the construction speed is fast.

Description

technical field [0001] The invention belongs to the field of prefabricated components, in particular to a self-supporting prefabricated concrete wall panel, a structural system and a manufacturing method thereof. Background technique [0002] The industrialization of construction has been the focus of construction and development in recent years, including vigorously promoting prefabricated buildings, encouraging prefabricated construction by construction companies, building a national prefabricated building production base, and increasing the proportion of prefabricated buildings in new buildings. In the reinforced prefabricated reinforced concrete shear wall and structural system in the prior art, the connector is an important factor to realize the construction safety of the prefabricated concrete structure, the aseismic bearing capacity and the aseismic ductility of the joint surface. At present, the commonly used connectors are flat steel plates. When a flat steel plate ...
