Description

Technical Field

[0001] The present application relates to the field of building technology, and in particular to a shear wall structure for building. Background Art

[0002] At present, shear walls are also called wind-resistant walls, earthquake-resistant walls or structural walls. They are walls in houses or structures that mainly bear horizontal and vertical loads caused by wind loads or earthquakes to prevent structural shear damage. They are also called earthquake-resistant walls and are generally made of reinforced concrete.

[0003] In on-site construction, shear walls are increasingly prefabricated and assembled, and prefabricated shear walls are usually connected by grouting of steel sleeves. This connection method requires the exposed vertical steel bars on the upper shear wall to enter the sleeves on the lower shear wall.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: during the transportation of prefabricated shear walls, vertical steel bars are prone to bending. Large bending angles can be corrected manually, but some small bending angles are not discovered in time by construction workers, resulting in inaccurate docking during assembly and docking, affecting construction, and therefore needs to be improved. Utility Model Content

[0005] In order to improve the above problems, the present application provides a shear wall structure for construction.

[0008] By adopting the above technical scheme, a rubber block and guide holes thereon are provided, and the guide holes are used to perform micro-bending adjustments on each vertical steel bar, thereby improving the docking accuracy between the vertical steel bar and the steel bar sleeve. At the same time, the guide holes are provided in an inverted cone shape, and when the upper shear wall is compressed and deformed, the rubber block can be used to improve the clamping force and fit sealing of the rubber block on the vertical steel bar, thereby improving the waterproof sealing of the upper shear wall and the lower shear wall.

[0009] Preferably, a deformation seam is provided on the upper end surface of the rubber block, the deformation seam extends along the arrangement direction of the guide holes, the deformation seam is connected to the guide holes, and the depth of the deformation seam is less than the depth of the guide holes.

[0010] By adopting the above technical solution, the setting of the deformation joint can provide a more flexible deformation space for the deformation of the upper end of the rubber block.

[0011] Preferably, both side surfaces of the rubber block are coated with waterproof glue.

[0012] By adopting the above technical solution, the provision of waterproof glue can further improve the waterproof sealing between the rubber block and the upper shear wall.

[0013] Preferably, a plurality of pre-positioning columns are provided, each of which is pre-inserted and connected between the guide hole and the corresponding steel sleeve, and the length of the pre-positioning column is less than one fifth of the length of the steel sleeve.

[0014] By adopting the above technical solution, since there are tolerances in the positions of each steel sleeve during the actual construction process, the setting of the pre-positioning column can ensure that each steel sleeve and the guide hole are coaxially arranged before the upper shear wall and the lower shear wall are spliced, thereby providing positioning and guiding effects for the subsequent precise insertion of the vertical steel bars and the steel sleeves, and improving the insertion stability of the vertical steel bars and the steel sleeves.

[0015] Preferably, the vertical steel bars are arranged side by side in at least two rows, the number of the steel bar sleeves is consistent with the number of the vertical steel bars, and the number of the rubber blocks is consistent with the number of rows of the vertical steel bars.

[0016] By adopting the above technical solution, at least two rows of vertical steel bars are arranged to improve the connection stability between the upper shear wall and the lower shear wall.

[0017] Preferably, a connecting belt is connected between two adjacent rubber blocks, and the connecting belt is located on a side of the rubber block that contacts the lower shear wall.

[0018] By adopting the above technical solution, the provision of the connecting belt facilitates the installation of the rubber block.

[0019] Preferably, the upper end of the lower shear wall is provided with an embedding groove for installing the rubber block and the connecting belt.

[0020] By adopting the above technical solution, the provision of the embedding groove will facilitate the installation of the connecting belt and the rubber block.

[0021] Preferably, a raised portion is provided on the upper end surface of the middle portion of the connecting belt.

[0022] By adopting the above technical solution, the setting of the raised part can make most of the pressure force applied to the connecting belt by the upper shear wall act on the raised part, so that the upper and lower surfaces of the raised part are in closer contact with the upper shear wall and the lower shear wall, further improving the waterproof sealing.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] By setting the rubber block and the guide holes thereon, the guide holes are used to adjust the micro-bending of each vertical steel bar, thereby improving the docking accuracy between the vertical steel bar and the steel bar sleeve. At the same time, the guide holes are set in an inverted cone shape. When the upper shear wall is compressed and deformed, the clamping force and the fitting sealing of the rubber block on the vertical steel bar can be improved, thereby improving the waterproof sealing of the upper shear wall and the lower shear wall.

[0025] Since there are tolerances in the positions of each steel sleeve during the actual construction process, the setting of pre-positioning columns can ensure that each steel sleeve and the guide hole are coaxially arranged before the upper shear wall and the lower shear wall are spliced, thereby providing positioning and guiding functions for the subsequent precise connection of the vertical steel bars and the steel sleeves, and improving the connection stability of the vertical steel bars and the steel sleeves.
