Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of staircase seismic isolation dampers, in particular to an assembled staircase seismic isolation damper with dustproof and weatherproof functions. Background Art
[0002] Currently, prefabricated staircases are constructed by first creating a mold, embedding rebar within the mold, and pouring concrete. The finished prefabricated staircase is then directly secured to the upper and lower foundations by overlapping and then covering the concrete. Because concrete is resistant to compression but not tension, this makes it difficult to secure the prefabricated staircases to the upper and lower foundations. This results in poor seismic resistance between the prefabricated staircase and the foundation. Patents are currently available that address these shortcomings.
[0003] For example, Chinese patent CN209244125U discloses a prefabricated staircase component comprising a staircase body and mounting brackets for supporting both ends of the staircase body. The mounting brackets are respectively arranged on adjacent floors. A pre-buried frame is provided within the staircase body. The top surfaces of the mounting brackets are respectively provided with mounting grooves for engaging with corresponding staircase bodies. The mounting brackets are respectively provided with seismic assemblies, which include a damper, a first seismic support, and a second seismic support. One end of the damper is mounted on the corresponding mounting bracket via the first seismic support, and the other end is mounted on the staircase body via the second seismic support. This invention has the advantages of simple structure and good seismic resistance.
[0004] Although the above patent solves the problem that the connection between the existing prefabricated stairs and the upper and lower bases is difficult to fix tightly, and the seismic resistance between the prefabricated stairs and the base is very poor, when it is used on site, the damper and the prefabricated stairs are in a separate form and need to be matched and assembled on the spot, which increases the construction steps. Moreover, when the stairs are seismically protected, the damper cannot be effectively protected from dust and weather, resulting in dust entering the damper after being placed for a long time, thereby affecting the normal operation of the damper and the seismic resistance of the damper. Therefore, it is necessary to design an assembled staircase seismic isolation damper with dust and weather resistance functions to solve the above problems. Summary of the Invention
[0005] In order to solve the above technical problems, the present invention provides an assembled staircase seismic isolation damper with dustproof and weather-resistant functions. The present invention aims to solve the problem that the installation process of the existing damper is cumbersome and cannot be effectively dustproof and weather-resistant.
[0006] One aspect of the present invention provides an assembled staircase seismic isolation damper with dustproof and weather-resistant functions, which mainly includes a damper body. The damper body is placed between a prefabricated wall and a prefabricated staircase. A storage groove is provided on the prefabricated staircase. One end of the damper body is hinged to the storage groove, and a limiting hole is provided at the other end of the damper body. A sealing rubber pad is fixedly connected to the bottom of the storage groove, and the outer wall of the damper body is connected to the sealing rubber pad.
[0007] A slot is provided at a position opposite to the hinge point of the prefabricated wall and the damper body, and one end of the damper body provided with a limiting hole and the movable end of the sealing rubber pad are placed in the slot;
[0008] A linkage groove is provided above the slot, and an insertion rod is provided in the linkage groove to match the limiting hole on the damper body;
[0009] Sealing plates are respectively provided on both sides of the sealing rubber pad; a closed cavity is formed among the sealing plates, the sealing rubber pad, the prefabricated wall and the prefabricated stairs; and the damper body is placed in the closed cavity.
[0010] Compared with the prior art, the present invention has the following beneficial effects:
[0011] The present invention flips the damper body and the sealing rubber pad so that the damper body is inserted into the receiving groove. The sealing rubber pad seals the port of the receiving groove on the surface of the prefabricated staircase, which can ensure that the damper body and the prefabricated staircase are assembled together and shipped together. After arriving at the installation site, they can be directly installed without on-site assembly of the damper, which simplifies the construction process and improves the installation efficiency of the damper.
[0012] Moreover, after the damper body of the present invention is installed between the prefabricated stairs and the prefabricated wall, the damper body is wrapped by a closed cavity formed by a sealing rubber pad, a sealing plate, a prefabricated wall and the prefabricated stairs, thereby achieving the effect of sealing the damper and preventing the damper from being affected by the shock-proof effect due to long-term exposure to the external environment.
[0013] Furthermore, the present invention adopts the following preferred embodiment:
[0014] The linkage groove is connected to the insertion rod through a spring, a long hole is opened on the side wall of the linkage groove, and a pulling rod passing through the long hole is arranged on the side wall of the insertion rod.
[0015] The slot includes a first slot and a second slot. The first slot is arranged corresponding to the hinge point of the prefabricated staircase and the damper body. The first slot is placed above the second slot, and the depth of the first slot is smaller than the depth of the second slot. The width of the first slot is also smaller than the width of the second slot.
[0016] The movable end of the sealing rubber pad is provided with a first magnetic block, and the interior of the second slot is provided with a second magnetic block that matches the first magnetic block.
[0017] A limit frame is further provided on the top of the storage slot corresponding to the prefabricated staircase, the movable end of the sealing rubber pad is adapted to the limit frame, and a third magnetic block that cooperates with the first magnetic block is provided inside the limit frame.

DETAILED DESCRIPTION
[0023] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments and the accompanying drawings. Here, the exemplary embodiments of the present invention and their descriptions are used to explain the present invention, but are not intended to limit the present invention.
[0024] like Figure 1 、 Figure 2 As shown, an assembled staircase seismic isolation damper with dustproof and weather-resistant functions mainly includes a damper body 5, and the damper body 5 is placed between a prefabricated wall 1 and a prefabricated staircase 2.
[0025] A mounting groove 3 is provided on the top of the prefabricated wall 1 , and the left end of the top of the prefabricated staircase 2 extends into the interior of the mounting groove 3 .
[0026] A storage groove 4 is provided at the bottom of the prefabricated staircase 2, and a rotating shaft 19 is installed on the inner wall of the bottom of the storage groove 4. A through hole adapted to the rotating shaft 19 is provided on the right end of the damper body 5. The damper body 5 is rotatably connected to the storage groove 4 through the cooperation of the rotating shaft 19 and the through hole.
[0027] The prefabricated staircase 2 is provided with a mounting seat 13 at the bottom of the storage slot 4. A sealing rubber pad 6 is fixedly connected to the mounting seat 13. The width of the sealing rubber pad 6 is slightly wider than the width of the storage slot 4 to ensure that the sealing rubber pad 6 can seal the storage slot 4. The middle portion of the sealing rubber pad 6 is fixedly connected to the middle portion of the damper body 5. When the damper body 5 rotates, the sealing rubber pad 6 can also rotate with it.
[0028] A slot 7 is located on the right side of the prefabricated wall 1 (the right side opposite the prefabricated staircase 2), opposite the hinge point of the damper body 5. Slot 7 consists of a first slot 701 and a second slot 702. The first slot 701 is positioned above the second slot 702, and its depth and width are both smaller than those of the second slot 702. In this embodiment, when the damper body 5 is flipped to a horizontal position, the left end of the damper body 5 extends into the first slot 701. The sealing rubber gasket 6 rotates with the damper body 5 to a horizontal position, with its left end inserted into the second slot 702.
[0029] In this embodiment, a limiting hole 11 is opened at the top of the left end of the damper body 5, and a linkage groove 8 is opened on the prefabricated wall 1 above the first slot 701. The inner wall of the top of the linkage groove 8 is connected with an insertion rod 10 through a spring 9. The insertion rod 10 is adapted to the limiting hole 11, and the insertion rod 10 is slidingly connected to the side wall of the linkage groove 8. After the damper body 5 is inserted into the first slot 701, the insertion rod 10 is plugged into the limiting hole 11 to realize the limitation of the damper body 5.
[0030] In this embodiment, in order to facilitate pulling the insertion rod 10, a pulling rod 12 is fixedly connected to the right side wall of the insertion rod 10, and a long hole is opened on the right side wall of the linkage groove 8. The pulling rod 12 passes through the long hole and extends to the outside of the linkage groove 8. By pulling the pulling rod 12 up and down, the insertion rod 10 can move up and down with the pulling rod 12.
[0031] In this embodiment, in order to ensure that the sealing rubber gasket 6 has a fixing effect, the movable end of the sealing rubber gasket 6 is fixedly connected to the first magnetic block 14, and the interior of the second slot 702 is fixedly connected to the second magnetic block 15. When the sealing rubber gasket 6 is inserted into the second slot 702, the first magnetic block 14 and the second magnetic block 15 are adsorbed together.
[0032] In order to facilitate the storage and sealing of the damper body 5, a limit frame 16 is fixedly installed at the position corresponding to the top of the storage groove 4 of the prefabricated staircase 2, and a third magnetic block 17 is fixedly connected to the inside of the limit frame 16. When the damper body 5 is rotated and stored in the storage groove 4, the movable end of the sealing rubber pad 6 is inserted into the inside of the limit frame 16 and is adsorbed together by the first magnetic block 14 and the third magnetic block 17.
[0033] In this embodiment, sealing plates 18 are respectively installed on the front and rear sides of the sealing rubber pad 6, the left side of each sealing plate 18 is fixedly sealed and connected to the prefabricated wall 1, the upper side of the sealing plate 18 is fixedly sealed and connected to the prefabricated staircase 2 with the right side, and the lower side of the sealing plate 18 is fixedly sealed and connected to the sealing rubber pad 6; a closed cavity is formed between the sealing plate 18, the sealing rubber pad 6, the prefabricated wall 1 and the prefabricated staircase 2, and the damper body 5 is placed in the closed cavity.
[0034] In application, when the prefabricated staircase 2 leaves the factory, the damper body 5 is placed in the receiving groove 4, and the movable end of the sealing rubber pad 6 is inserted into the limit frame 16. The sealing rubber pad 6 is fixed to the limit frame 16 by adsorption of the first magnetic block 14 and the second magnetic block 15, and the sealing rubber pad 6 is tightly fitted with the bottom of the prefabricated staircase 2, which plays a role in sealing and protecting the damper body 5; when the prefabricated wall 1 and the prefabricated staircase 2 are installed, the left side of the prefabricated staircase 2 is inserted into the installation groove 3 of the prefabricated wall 1 and fixed, and then the movable end of the sealing rubber pad 6 is taken out of the limit frame 16, and the pulling rod 12 is moved upward, and the insertion rod 10 also moves upward as the pulling rod 12 moves upward, and then the damper body 5 is flipped downward. After the damper body 5 is fully inserted into the first slot 701, the pulling rod is released. 12. Under the elastic action of the spring 9, the insertion rod 10 pops out, and the insertion rod 10 is inserted into the limiting hole 11 to limit and fix the damper body 5, and at the same time, the sealing rubber pad 6 is inserted into the second slot 702, and the sealing rubber pad 6 is fixed in the second slot 702 by the adsorption of the first magnetic block 14 and the second magnetic block 15, and the front and rear of the sealing rubber pad 6 are tightly fitted with the sealing plate 18, and then the sealing plates 18 are respectively installed on the front and rear sides of the sealing rubber pad 6 to ensure that the prefabricated wall 1, the prefabricated stair 2 and the front and rear of the sealing rubber pad 6 are tightly fitted with the sealing plate 18, and a closed cavity is formed between the sealing plate 18, the sealing rubber pad 6, the prefabricated wall 1 and the prefabricated stair 2, and the damper body 5 is placed in the closed cavity, thereby achieving the effect of sealing the damper 5.
[0035] When the prefabricated staircase 2 needs to be dismantled, the sealing plates 18 on the front and rear sides are first removed, and then the sealing rubber pad 6 is pulled out of the second slot 702, and then the pulling rod 12 is pulled upward. The movement of the pulling rod 12 drives the insertion rod 10 to move. After the insertion rod 10 moves out of the limiting hole 11, the damper body 5 can be flipped upward. The flipping of the damper body 5 drives the sealing rubber pad 6 to flip. When the damper body 5 is flipped to the inside of the storage groove 4, the sealing rubber pad 6 can seal the opening of the storage groove 4. At this time, the sealing rubber pad 6 is inserted into the inside of the limiting frame 16, and the first magnetic block 14 and the third magnetic block 17 are attracted to each other to achieve the effect of limiting the sealing rubber pad 6.
[0036] The present invention flips the damper body and the sealing rubber pad so that the damper body is inserted into the receiving groove. The sealing rubber pad seals the port of the receiving groove on the surface of the prefabricated staircase, which can ensure that the damper body and the prefabricated staircase are assembled together and shipped together. After arriving at the installation site, they can be directly installed without on-site assembly of the damper, which simplifies the construction process and improves the installation efficiency of the damper.
[0037] Moreover, after the damper body of the present invention is installed between the prefabricated stairs and the prefabricated wall, the damper body is wrapped by a closed cavity formed by a sealing rubber pad, a sealing plate, a prefabricated wall and the prefabricated stairs, thereby achieving the effect of sealing the damper and preventing the damper from being affected by the shock-proof effect due to long-term exposure to the external environment.
[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention are included in the scope of protection of the present invention.
