Example Embodiment

[0081] Example one see figure 1 with Figure 4 As shown, a self-supporting precast concrete wall panel includes a board body 10, and the shape of the board body can be in-line, 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 the prefabricated vertical steel bar 11, the prefabricated horizontal steel bar 12 and the prefabricated part concrete 13, the vertical connecting end of the prefabricated part has a vertical connector, the vertical The vertical connecting member includes the vertical steel bars 11 of the prefabricated part protruding from the edge end surface of the prefabricated part and two or more vertical shear-resistant connecting members 3. In this embodiment, there are a total of four vertical shear connectors, which are arranged symmetrically from the left to the right, and also from the top to the bottom.

Example Embodiment

[0090] See the second embodiment figure 2 with Figure 4 As shown, the difference from the first embodiment is that the vertical shear connection member 3 is a steel member arranged vertically along the prefabricated part 1.

Example Embodiment

[0091] See the third embodiment image 3 with Figure 4 As shown, the difference from the second embodiment is that the prefabricated part 1 has horizontal connectors on both horizontal sides, and the horizontal connectors include two symmetrical horizontal shear connectors 4 extending from the edge of the prefabricated part. The horizontal shear connector 4 is partially pre-embedded in the prefabricated part, and the pre-embedded part is wrapped by the vertical steel bars 11 of the prefabricated part and the horizontal steel bars 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 ...
