[0002] Formwork shear wall is a structural wall, usually used in the load-bearing structure of a building. In order to facilitate pouring, steel bars are set in the formwork. When the steel bars are unevenly distributed or the steel bar configuration does not meet the structural requirements, the stability of the steel bar components will be poor, so that the concrete after pouring will be unevenly stressed on the formwork, which will cause the formwork to explode or expand easily. Utility Model Content

[0005] The connecting piece comprises a steel sheet embedded in the formwork shell plate, an inner buckle plugged with one end of the tie hook is fixedly arranged on the inner side of the steel sheet, and an outer locking buckle for the inner steel net to pass through is fixedly arranged on the outer side of the steel sheet.

[0006] Preferably, the steel bar frame is composed of a plurality of vertical steel bars and a plurality of transverse steel bars, and the connection positions between the vertical steel bars and the transverse steel bars are fixed by wire binding.

[0007] Preferably, both ends of the knot hook are in the shape of curved hooks.

[0012] 1. The assembled non-disassembly formwork shear wall is provided with tie hooks, connectors and built-in steel mesh. The tie hooks can provide inward pulling force to the connectors, and the connectors can also provide pulling force to the built-in steel mesh, which can increase the tensile bearing capacity of the built-in steel mesh. At the same time, the external load can be evenly distributed to the formwork plate, so that the formwork plate is evenly stressed, effectively avoiding the occurrence of formwork explosion or expansion, and further improving the overall compressive strength of the formwork plate.

[0013] 2. The assembled non-disassembly formwork shear wall is arranged by staggering the outer locking buckles on adjacent steel sheets horizontally and vertically, so that the adjacent outer locking buckles can connect the horizontally and vertically distributed mesh strips on the built-in steel mesh to achieve uniform distribution of tension.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] With the development of the construction industry and technological progress, prefabricated buildings have become a trend. They have the advantages of fast construction speed, controllable quality, and resource conservation, and have received widespread attention and application. In this context, prefabricated formwork-free shear walls have emerged as a new type of structure. Prefabricated formwork-free shear walls combine the characteristics of prefabricated buildings and formwork shear walls, and adopt a combination of factory prefabrication and on-site installation, making the construction process more efficient and saving time and labor costs. At the same time, the decorative outer surface of the formwork shear wall also adds beauty to the building, which meets the needs of contemporary architectural design.

[0024] Based on the technical defects of the existing technology that cause mold explosion or mold expansion due to uneven force on the mold shell, please refer to Figure 1-Figure 5 The utility model provides an assembled non-disassembly formwork shear wall, which can evenly distribute the external load to the formwork plate 3, so that the formwork plate 3 is evenly stressed, and the formwork plate 3 is effectively prevented from exploding or expanding. A plurality of tie hooks 2 for limiting the steel bars are tied and connected on the inner side of the steel frame 1, and both ends of the tie hooks 2 are connected with connecting parts 4. The outer side of the connecting part 4 is provided with a built-in steel mesh 5, and the connecting part 4 and the built-in steel mesh 5 are both pre-buried in the formwork plate 3; the tie hooks 2 can provide an inward pulling force to the connecting part 4, and the connecting part 4 can also provide a pulling force to the built-in steel mesh 5, thereby increasing the tensile bearing capacity of the built-in steel mesh 5. At the same time, under the action of the built-in steel mesh 5, the compressive strength of the formwork plate 3 can be improved.

[0025] To increase the tensile strength of the tie hook 2, please refer to Figure 4 The connecting piece 4 includes a steel sheet 41 embedded in the formwork plate 3, an inner buckle 42 is fixedly provided on the inner side of the steel sheet 41 and plugged into one end of the tie hook 2, and an outer buckle 43 is fixedly provided on the outer side of the steel sheet 41 for the built-in steel mesh 5 to pass through. The inner buckle 42 is used to form a pulling force on one end of the tie hook 2, so that the tie hook 2 can be better connected to the formwork plate 3.

[0026] In order to enhance the strength and tensile resistance of concrete after pouring, the steel frame 1 is composed of a plurality of vertical steel bars 11 and a plurality of transverse steel bars 12. The connection positions between the vertical steel bars 11 and the transverse steel bars 12 are fixed by wire binding. The transverse steel bars 12 are used to control the transverse deformation and seismic resistance of the concrete member, and the longitudinal steel bars are used to withstand the tension and bending moment of the concrete member.

[0027] In order to improve the connection effect between the tie hook 2 and the connector 4, the two ends of the tie hook 2 are hook-shaped, and the tie hook 2 can be fixed to the connector 4 by plugging, so that the tie hook 2 can provide a better pulling effect.

[0028] In order to facilitate the inward pulling force on the internal steel mesh 5 , the external locking buckle 43 is “U”-shaped, and there are two external locking buckles 43 on a single steel sheet 41 , which can achieve a better contact effect with the internal steel mesh 5 .

[0029] To facilitate the outer locking buckles 43 to form uniform tension on the inner steel mesh 5, the outer locking buckles 43 on adjacent steel sheets 41 are arranged to be staggered horizontally and vertically, so that adjacent outer locking buckles 43 can connect the horizontally and vertically distributed mesh strips on the inner steel mesh 5 to achieve uniform distribution of tension.

[0030] In order to improve the strength and corrosion resistance of the built-in steel mesh 5, the built-in steel mesh 5 is specifically a galvanized steel mesh. The galvanizing treatment can form a layer of zinc on the surface of the steel mesh, which can effectively block the corrosion of the steel mesh by air, water and chemicals, and extend the service life of the steel mesh. After the galvanizing treatment, the surface hardness of the galvanized steel mesh increases, the strength is improved, the wear resistance and tensile strength are improved, and it has good mechanical properties.

[0031] It can be known from the above embodiments that the formwork plate 3 is prefabricated in the factory first, and during the prefabrication process, the tie hooks 2, the connectors 4 and the built-in steel mesh 5 are all embedded in the formwork plate 3. After the prefabrication, it is transported to the construction site, and the casting work can be carried out after the reinforcement frame 1 is tied.

[0032] It should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
