Technical Field

[0001] The utility model relates to the technical field of building engineering, in particular to a prefabricated assembled shear wall. Background Art

[0002] Compared with traditional concrete buildings, steel structure buildings use steel plates or steel sections instead of reinforced concrete, which has higher strength and better earthquake resistance. And because the components can be manufactured in factories and installed on site, the construction period is greatly reduced. Since steel can be reused, it can greatly reduce construction waste and is more environmentally friendly. Therefore, it is widely adopted by countries around the world and applied in industrial and civil buildings. At present, the application of steel structure buildings in high-rise and super high-rise buildings is becoming more and more mature, gradually becoming the mainstream construction technology, and is the development direction of future buildings.

[0003] A prefabricated assembled shear wall is disclosed in a Chinese utility model patent with publication number CN213626171U, which includes an upper shear wall, a lower shear wall, a connector and high-strength bolts; a first connector is prefabricated in the lower end surface of the upper shear wall, the first connector includes a first connector end, a second connector is prefabricated in the upper end surface of the lower shear wall, the second connector includes a second connector end, the connector has an upper slot for plugging with the first connector and a lower slot for plugging with the second connector, some high-strength bolts are connected between the first connector and the connector, and another part of the high-strength bolts are connected between the second connector and the connector.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: in order to improve the structural strength, the above-mentioned device uses a plurality of high-strength bolts distributed at equal intervals to fix the second connector to the connecting member. The actual installation process is difficult and inefficient, which is not conducive to improving the user experience of the staff. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a prefabricated assembled shear wall.

[0006] The above technical purpose of the utility model is achieved through the following technical scheme: a prefabricated assembled shear wall, including an upper shear wall and a lower shear wall, the bottom surface of the upper shear wall is fixed with a mounting rod, the upper surface of the lower shear wall is fixed with a fixing rod, the upper surface of the fixing rod is provided with a mounting groove matching the mounting rod, and the lower shear wall is provided with a limiting component for limiting the mounting rod.

[0007] By adopting the above technical solution, when the staff needs to connect the upper shear wall and the lower shear wall, the staff needs to fix the fixing rod and the lower shear wall to each other, and fix the installation rod and the upper shear wall to each other. Further, the staff needs to connect the lower shear wall to the ground to keep the lower shear force stable. Subsequently, the staff only needs to connect the installation rod and the installation groove to automatically start the limit assembly, and then the installation rod remains stable under the action of the limit assembly, so that the upper shear wall and the lower shear wall remain stable, and the installation difficulty is relatively low.

[0008] Furthermore, a plurality of gun nails distributed at equal intervals are arranged on the side wall of the fixing rod.

[0009] By adopting the above technical solution, after the mounting rod and the mounting groove are connected to each other, the staff only needs to spray nails onto the side wall of the fixing rod through an air gun to keep the fixing rod and the mounting rod together under the action of the nails, thereby further improving the stability of the upper shear wall.

[0010] Furthermore, a limiting groove is provided on the side wall of the mounting rod, and a limiting hole matching the limiting groove is provided on the inner wall of the mounting groove. The limiting assembly includes a limiting plate slidably arranged in the limiting groove and a limiting spring with one end fixed to the side wall of the limiting plate, and the other end of the limiting spring is fixed to the inner wall of the limiting groove.

[0011] By adopting the above technical solution, when the staff connects the installation rod and the installation groove, the staff needs to connect the installation grooves at one end of the installation rod, so that the limit plate can be completely moved into the limit groove under the action of the inner wall of the installation groove. Subsequently, the staff needs to push the upper shear wall, so that the upper shear wall and the lower shear wall are gradually aligned, and the limit groove and the limit hole are gradually aligned. When the limit groove and the limit hole are aligned, the limit plate is connected to the limit hole under the action of the limit spring, so that the installation rod can be kept stable under the action of the limit plate, thereby keeping the upper shear wall and the lower shear wall stable.

[0012] Furthermore, a threaded hole communicating with the limiting hole is formed on the side wall of the fixing rod, and a threaded rod for driving the limiting plate is threadedly connected in the threaded hole.

[0013] By adopting the above technical solution, when the staff needs to separate the upper shear wall from the lower shear wall, the staff only needs to connect the threaded rod and the threaded hole and rotate the threaded rod to make the threaded rod press against the fiberboard, so that the limiting plate is gradually separated from the limiting hole under the action of the threaded rod. Afterwards, the staff only needs to push the upper shear wall to separate the installation rod from the installation groove.

[0014] Furthermore, an accommodating groove which is in communication with the mounting groove is formed on the upper surface of the fixing rod, and a width of the accommodating groove is greater than a width of the mounting groove.

[0015] Furthermore, first inclined surfaces are provided on two inner walls of the accommodating groove close to the mounting groove.

[0016] Furthermore, a second inclined surface is provided on an edge where the side wall of the limiting plate away from the limiting spring intersects with one of its adjacent edges.

[0017] By adopting the above technical solution, the width of the receiving groove is greater than the width of the installation groove. When the staff installs the installation rod, the staff only needs to connect the installation rod with the receiving groove to make the installation rod initially stable. Afterwards, the staff only needs to push the upper shear wall to make the installation rod connect with the installation groove under the action of the first inclined surface, and make the limiting plate completely move into the limiting groove under the action of the second inclined surface, thereby further reducing the difficulty of operation for the staff.

[0018] Furthermore, a cover plate for closing the threaded hole is provided on the threaded hole.

[0019] By adopting the above technical solution, when the staff does not need to use the threaded hole, the staff only needs to remove the threaded rod and connect the cover plate and the threaded hole to each other, so that the cover plate can close the threaded hole, thereby reducing the probability of impurities entering the limit groove through the threaded hole.

[0020] In summary, the utility model has the following beneficial effects:

[0021] 1. In this application, when the staff needs to connect the upper shear wall and the lower shear wall, the staff needs to fix the fixing rod and the lower shear wall to each other, and fix the installation rod and the upper shear wall to each other. Furthermore, the staff needs to connect the lower shear wall to the ground to keep the lower shear force stable. Afterwards, the staff only needs to connect the installation rod and the installation groove to automatically start the limit assembly, and then the installation rod remains stable under the action of the limit assembly, so that the upper shear wall and the lower shear wall remain stable, and the installation difficulty is relatively low;

[0022] 2. In the present application, when the staff connects the installation rod and the installation slot, the staff needs to connect the installation slots at one end of the installation rod, so that the limit plate can be completely moved into the limit slot under the action of the inner wall of the installation slot. Afterwards, the staff needs to push the upper shear wall, so that the upper shear wall and the lower shear wall are gradually aligned, and the limit slot and the limit hole are gradually aligned. When the limit slot and the limit hole are aligned, the limit plate is connected to the limit hole under the action of the limit spring, so that the installation rod can remain stable under the action of the limit plate, thereby keeping the upper shear wall and the lower shear wall stable;

[0023] 3. In this application, when the staff needs to separate the upper shear wall from the lower shear wall, the staff only needs to connect the threaded rod and the threaded hole, and rotate the threaded rod to make the threaded rod press against the fiberboard, so that the limit plate is gradually separated from the limit hole under the action of the threaded rod. Then, the staff only needs to push the upper shear wall to separate the installation rod from the installation groove. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0031] like Figure 1-5 As shown, the embodiment of the present application discloses a prefabricated assembled shear wall, including an upper shear wall 1, a lower shear wall 11, a mounting rod 2, a fixing rod 21, a limit assembly 4, a nail gun 5, a threaded rod 61 and a cover plate 9. The mounting rod 2 is a rectangular rod-shaped structure, and the mounting rod 2 is fixed to the bottom surface of the upper shear wall 1. The fixing rod 21 is a rectangular rod-shaped structure, and the fixing rod 21 is fixed to the upper surface of the lower shear wall 11.

[0032] There are multiple nails 5 distributed evenly on the side wall of the fixing rod 21. When the mounting rod 2 and the mounting groove 3 are connected to each other, the staff only needs to spray the nails 5 onto the side wall of the fixing rod 21 through an air gun, so that the fixing rod 21 and the mounting rod 2 can be maintained under the action of the nails 5, thereby further improving the stability of the upper shear wall 1.

[0033] The upper surface of the fixing rod 21 is provided with a mounting groove 3 that matches the mounting rod 2, the side wall of the mounting rod 2 is provided with a limiting groove 31, and the inner wall of the mounting groove 3 is provided with a limiting hole 32 that matches the limiting groove 31. The limiting assembly 4 is arranged on the lower shear wall 11, and is used to limit the mounting rod 2. The limiting assembly 4 includes a limiting plate 41 and a limiting spring 42. The limiting plate 41 is a rectangular plate-shaped structure, and the limiting plate 41 is slidably arranged in the limiting groove 31. One end of the limiting spring 42 is fixed to the side wall of the limiting plate 41, and the other end of the limiting spring 42 is fixed to the inner wall of the limiting groove 31.

[0034] When the staff connects the mounting rod 2 and the mounting groove 3, the staff needs to connect the mounting grooves 3 at one end of the mounting rod 2, so that the limiting plate 41 can be completely moved into the limiting groove 31 under the action of the inner wall of the mounting groove 3. Subsequently, the staff needs to push the upper shear wall 1, so that the upper shear wall 1 and the lower shear wall 11 are gradually aligned, and the limiting groove 31 and the limiting hole 32 are gradually aligned. When the limiting groove 31 and the limiting hole 32 are aligned, the limiting plate 41 is connected to the limiting hole 32 under the action of the limiting spring 42, so that the mounting rod 2 can be kept stable under the action of the limiting plate 41, thereby keeping the upper shear wall 1 and the lower shear wall 11 stable.

[0035] A threaded hole 6 communicating with the limiting hole 32 is formed on the side wall of the fixing rod 21 . A threaded rod 61 is threadedly connected in the threaded hole 6 for driving the limiting plate 41 .

[0036] When the staff needs to separate the upper shear wall 1 from the lower shear wall 11, the staff only needs to connect the threaded rod 61 with the threaded hole 6 and rotate the threaded rod 61 to make the threaded rod 61 press against the fiberboard, so that the limiting plate 41 is gradually separated from the limiting hole 32 under the action of the threaded rod 61. Then, the staff only needs to push the upper shear wall 1 to separate the mounting rod 2 from the mounting groove 3.

[0037] The upper surface of the fixing rod 21 is provided with a receiving groove 7 which is interconnected with the mounting groove 3. The width of the receiving groove 7 is greater than the width of the mounting groove 3. The two inner walls of the receiving groove 7 close to the mounting groove 3 are provided with a first inclined surface 71, and the side wall of the limiting plate 41 away from the limiting spring 42 is provided with a second inclined surface 8 on the edge intersecting with one of its adjacent edges.

[0038] The width of the receiving groove 7 is greater than the width of the installation groove 3. When the staff installs the installation rod 2, the staff only needs to connect the installation rod 2 with the receiving groove 7 to make the installation rod 2 initially stable. Afterwards, the staff only needs to push the upper shear wall 1 to make the installation rod 2 connect with the installation groove 3 under the action of the first inclined surface 71, and make the limiting plate 41 completely move into the limiting groove 31 under the action of the second inclined surface 8, thereby further reducing the difficulty of the staff's operation.

[0039] In order to reduce the probability of impurities entering the limiting groove 31 through the threaded hole 6, a cover plate 9 for closing the threaded hole 6 is provided on the threaded hole 6. When the staff does not need to use the threaded hole 6, the staff only needs to remove the threaded rod 61 and connect the cover plate 9 and the threaded hole 6 to each other, so that the cover plate 9 can close the threaded hole 6, thereby reducing the probability of impurities entering the limiting groove 31 through the threaded hole 6.

[0040] The use principle of a prefabricated assembled shear wall in this embodiment is as follows: when the staff needs to connect the upper shear wall 1 and the lower shear wall 11, the staff needs to fix the fixing rod 21 and the lower shear wall 11 to each other, and fix the installation rod 2 and the upper shear wall 1 to each other. Further, the staff needs to connect the lower shear wall 11 to the ground to keep the lower shear force stable. Subsequently, the staff only needs to connect the installation rod 2 and the installation groove 3 to automatically start the limit assembly 4, and then the installation rod 2 is kept stable under the action of the limit assembly 4, so that the upper shear wall 1 and the lower shear wall 11 are kept stable, and the installation difficulty is relatively low.

[0041] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
