Abstract
Description
Technical Field
[0001] The utility model relates to shear walls, and more specifically to prefabricated shear walls. Background Art
[0002] With the development of building industrialization, prefabricated buildings have emerged in various places. The key to prefabricated buildings is how to effectively connect the precast components made in the factory into an integral building. The firmness and reliability of the connection between components directly affect the safety of the overall building structure. Existing prefabricated shear wall structures mostly adopt sleeve grouting connection, steel bar welding connection or lapped grouting anchor connection, forming vertical joints between two shear walls, and then adopting a connection method of steel bar lapping and post-cast concrete in the vertical joints. However, it is found in actual use that in this existing method, due to the fixed length of the steel bars embedded in the shear wall, when there is a distance difference, it is necessary to additionally correct the shear wall to accumulate pouring construction, and correcting the shear wall may also result in poor adhesion between the poured area and the shear wall after pouring and poor seismic performance. Therefore, a prefabricated shear wall is needed, which can adapt to pouring requirements of different lengths without correction.
[0003] Combined with the above reasons, how to adapt to pouring requirements of different lengths without correction is exactly the problem considered in this application. Summary of the Utility Model
[0004] Aiming at the deficiencies of the existing technology, a prefabricated shear wall is provided, which can adapt to pouring requirements of different lengths without correction.
[0005] To achieve the above object, the following technical solutions are provided: A prefabricated shear wall includes a wall body. A plurality of splicing platforms are fixedly connected to the side of the wall body. An insertion member for positioning a pouring auxiliary plate is fixedly connected to the middle of the splicing platform. Hooks are symmetrically arranged at both ends of the insertion member and are fixedly connected to the splicing platform. A first interval is provided between the hook and the insertion member. A protection member fixedly connected to the splicing platform is provided on the side of the hook away from the insertion member, and the length of the protection member is not shorter than the length of the hook.
[0006] In summary, the above technical solutions have the following beneficial effects: The utility model uses additional splicing platforms as the connection basis of the prefabricated shear wall, and uses hooks and additional connecting steel bars as the connection medium, which can avoid the situations of difficult handling and difficult correction of the shear wall in the existing technology. Directly processing steel bars is more time-saving and labor-saving, thus achieving the purpose of adapting to pouring requirements of different lengths without correction.

[0015] The present utility model will be further described in detail below with reference to the drawings and embodiments. The same components are denoted by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "bottom surface" and "top surface", "inner" and "outer" refer to the directions towards or away from the geometric center of a specific component respectively.
[0016] Refer to Figures 1-3 As shown, the precast shear wall includes a wall 1. A plurality of splicing tables 2 are fixedly connected to the side of the wall 1. A plug-in part 3 for positioning the casting auxiliary plate is fixedly connected to the middle of the splicing table 2. Symmetrically arranged hooks 4 fixedly connected to the splicing table 2 are respectively provided at both ends of the plug-in part 3. A first interval 41 is provided between the hook 4 and the plug-in part 3. A protection part 5 fixedly connected to the splicing table 2 is provided on the side of the hook 4 away from the plug-in part 3, and the length of the protection part 5 is not shorter than the length of the hook 4;
[0017] In the prior art, the precast shear wall is usually integrally cast with the steel bars extending out of the outside for connection. The connection between the external steel bars needs to be assisted by accessories such as rolling belts. When the casting length does not match the length of the steel bars, it is necessary to cut short or extend. When cutting short, large equipment cannot be used due to the presence of the wall 1. When extending, more steel bars need to be additionally assembled, which is extremely time-consuming during construction. Therefore, the hook 4 is provided. In this way, the steel bars used for mutual connection during casting are no longer the steel bars extending from the precast shear wall, but another steel bar is used as the connection medium. When needed, only the top of the steel bar needs to be bent into a ring shape to be installed on the hook 4. And since the steel bar is not connected to the wall 1, equipment such as a cutting machine or a bending machine can be directly used for modification, and the shear wall does not need to be corrected, so as to achieve the purpose of adapting to different casting length requirements without correction;
[0018] The connector 3 can be used for the insertion of the auxiliary support plate. There is a first gap 41 between the hook 4 and the connector 3, so that it can be adapted to directly insert a single thick auxiliary plate with an I-shaped socket, or adapt to the insertion of a common thin auxiliary plate into the first gap 41 between the hook 4 and the connector 3, so as to achieve the purpose of adapting to pouring requirements of different lengths without correction;
[0019] In addition, a protective member 5 is provided to protect the hook 4 to prevent the hook 4 from being broken during transportation. Whether the auxiliary plate is used or not will not directly affect the overall pouring construction. Therefore, even if the connector 3 is broken, it does not affect the use;
[0020] The utility model uses an additional splicing table 2 as the connection foundation of the precast shear wall. Through the hook 4 and additional connecting steel bars as the connection medium, it can avoid the situations of difficult handling and difficult correction of the shear wall in the prior art. Directly processing the steel bars is more time-saving and labor-saving, so as to achieve the purpose of adapting to pouring requirements of different lengths without correction.
[0021] Further, a plurality of vertical steel bars 11 extending to the splicing table 2 are provided in the wall body 1, and a plurality of annular positioning members 12 are fixedly connected to the plurality of vertical steel bars 11. The plurality of annular positioning members 12 respectively extend into the connector 3, the hook 4 and the protective member 5;
[0022] A plurality of horizontal steel bars 13 extending to the splicing table 2 are also provided in the wall body 1, and the horizontal steel bars 13 and the vertical steel bars 11 are arranged in a composite connection;
[0023] Due to the structural function of the shear wall itself, it is necessary to set the vertical steel bars 11 and the horizontal steel bars 13 as the basic structure. In order to prevent the splicing table 2 from detaching from the wall body 1, the annular positioning members 12 are used to increase the actual contact area, enhance the connection strength of the connector 3, the hook 4 and the protective member 5, and at the same time increase the connection strength of the splicing table 2 in disguise. Since the precast shear wall itself needs to be used in cooperation with the cast-in-place shear wall, the precast shear wall has a relatively long horizontal length. The horizontal steel bars 13 and the vertical steel bars 11 can form a composite connection similar to the fabric connection structure, so as to strengthen the overall connection strength.
[0024] Further, a second gap 42 is provided between the hook 4 and the protective member 5, and the second gap 42 can also be used to insert the auxiliary plate, so as to increase the optional range of the auxiliary plate.
[0025] Further, the side surface of the protective member 5 is arranged in an inclined shape from the outside to the inside and is concave at the central position;
[0026] A first groove 51 is provided on the side of the protective member 5 facing the hook 4, and a second groove 31 is provided on the side of the connector 3 facing the hook 4;
[0027] The plug-in part 3, the hook 4 and the protection part 5 are all provided with rounded corners;
[0028] The plug-in part 3, the hook 4 and the protection part 5 will be immersed in the cement during pouring. Therefore, it is necessary to increase the contact surface with the cement as much as possible to strengthen the connection between the precast shear wall and the cast-in-place shear wall. The side surface of the protection part 5 is inclined from the outside to the inside and is concave at the center position. In addition, the plug-in part 3, the hook 4 and the protection part 5 are all provided with rounded corners, which can guide the cement to cover and wrap all components as much as possible during pouring. And after the cement solidifies, its volume will expand slightly, so that it can be completely stuck in the first groove 51 and the second groove 31 to form an embedded structure and increase the stability of the overall connection;
[0029] In addition, the plug-in part 3, the hook 4 and the protection part 5 are all provided with rounded corners, which can also prevent sharp edges and corners from scratching the staff or causing damage due to collision during transportation. On the other hand, it can increase the contact area of the cement, thereby strengthening the connection stability.
[0030] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
