Description

Technical Field

[0001] The invention relates to the technical field of engineering construction, and in particular to a cover plate structure for a seismic isolation joint adjacent to a wall. Background Art

[0002] Isolation joints refer to the gaps pre-set to reduce or prevent collisions between adjacent structural units caused by earthquakes. Buildings in earthquake-fortified areas must fully consider the impact of earthquakes on the buildings.

[0003] According to existing data and atlases, there is a relatively mature seismic isolation joint cover plate structure for seismic isolation joints passing through relatively open areas. The seismic isolation joint cover plates in open areas can adapt to expansion and contraction deformation in any horizontal direction, but this structure cannot cope with special seismic isolation joint nodes, such as the seismic isolation joint cover plates in the area adjacent to the wall. Under the action of seismic force, the full-length seismic isolation joint cover plates will be warped, but it is easy to collide with the surrounding existing buildings and damage the existing building structure. Summary of the invention

[0004] The purpose of the present invention is to overcome the defects of the prior art and provide a cover plate structure for the wall-adjacent area of ​​the seismic isolation joint to solve the problem that the conventional seismic isolation joint cover plates in the prior art are prone to collide with the wall after being hit by an earthquake, causing damage to the wall.

[0005] To achieve the above-mentioned purpose, the present invention provides a cover plate structure for the area of ​​seismic isolation joints adjacent to the wall, which is used to cover the seismic isolation joints between the ground foundations adjacent to the wall, and the cover plate structure includes a seismic isolation flap and a swing plate;

[0006] The seismic isolation flap cover is arranged above the seismic isolation seam, and an anti-stuck gap is left between the seismic isolation flap close to the wall and the wall;

[0007] The swing plate covers the anti-stuck gap, and one end of the swing plate is horizontally rotated near the wall and connected to the top of the ground foundation on that side, and the other end of the swing plate is placed on the top of the ground foundation on the other side.

[0008] By adopting this technical solution, a conventional seismic isolation flap covering the seismic isolation joint is connected to the ground foundation as a cover in the horizontal direction, and an anti-stuck gap is reserved between the seismic isolation flap and the wall near the wall to avoid the seismic isolation flap from colliding with the wall during an earthquake. At the same time, a horizontally rotatable swing plate is provided to cover the anti-stuck gap. The seismic isolation flap is cooperated with to maintain the coverage of the seismic isolation joint while adapting to the displacement and deformation of the walls on both sides of the seismic isolation joint. This solves the problem of the conventional cover plate being easily damaged by the wall when it is adjacent to the wall while providing the covering function of the conventional cover plate.

[0009] Furthermore, a cover plate groove is commonly provided on the ground foundation on both sides of the seismic isolation joint, and the seismic isolation flap is arranged inside the cover plate groove.

[0010] By adopting this technical solution: the setting height of the seismic isolation flap and the swing plate is lowered, the coverage of the seismic isolation joint is maintained while ensuring the flatness of the ground.

[0011] Further, it also includes an articulated support and a wedge-shaped support;

[0012] One end of the seismic isolation flap is flipped inside the cover plate groove and connected to the ground foundation on this side through the hinged support;

[0013] The wedge-shaped support is connected to the ground foundation on the other side inside the cover plate groove, and the top surface of the wedge-shaped support matches the inclined surface of the end surface of the seismic isolation flap.

[0014] By adopting this technical solution, the hinged support cooperates with the wedge-shaped support, so that the seismic isolation flap can adapt to the changes in the seismic isolation joint caused by earthquakes inside the cover plate groove, and complete the corresponding action to maintain coverage of the seismic isolation joint.

[0015] Furthermore, it also includes a sliding support, which is connected to the ground foundation on the side where the wedge-shaped support is located inside the cover plate groove, and the sliding support supports the seismic isolation flap.

[0016] By adopting this technical solution, a sliding support is provided to reduce the contact friction between the seismic isolation flap and the cover plate groove, thereby increasing the automatic displacement adjustment efficiency of the seismic isolation flap inside the cover plate groove to adapt to earthquakes.

[0017] Furthermore, it also includes a side seam cover plate, which is fixed to the top of one end of the seismic isolation flap and the wedge-shaped support, and the side of the side seam cover plate away from the side connected to the seismic isolation flap is attached to the top of the ground foundation on this side.

[0018] By adopting this technical solution, the side seam cover can cover the gap formed by the seismic isolation flap and the top of the ground foundation, thereby increasing the flatness and aesthetics of the ground.

[0019] Furthermore, the top edge of the side seam cover plate is chamfered.

[0020] By adopting this technical solution, the distance between the edge of the side seam cover plate and the ground foundation is reduced to avoid the problem of tripping caused by the side seam cover plate.

[0021] Furthermore, it also includes an adapter, and one end of the swing plate is rotatably connected to the top of the ground foundation on this side through the adapter near the corner where the wall is located;

[0022] The ground foundation on this side is the ground foundation on which the seismic isolation flap is flipped and connected.

[0023] By adopting this technical solution, the rotating connection side of the swing plate is set to be on the same side as the flipping connection side of the seismic isolation flap, which can reduce the mutual influence between the swing plate and the seismic isolation flap, better adapt to the earthquake to complete the corresponding position adjustment, and maintain full coverage of the seismic isolation joint.

[0024] Furthermore, the corner arc processing has a center point that is concentric with the location of the adapter.

[0025] By adopting this technical solution, the swing plate is rotated and connected with the arc corner treatment to avoid collision with the wall during rotation, thereby reducing the distance between the swing plate and the wall and increasing the coverage area of ​​the plane seismic isolation joint.

[0026] Furthermore, the top edge of the swing plate is chamfered.

[0027] By adopting this technical solution, the distance between the edge of the swing plate and the ground foundation is reduced to avoid the problem of tripping caused by the swing plate.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] A conventional seismic isolation flap covering the seismic isolation joint is connected to the ground foundation as a cover in the horizontal direction, and an anti-stuck gap is reserved between the seismic isolation flap near the wall and the wall to prevent the seismic isolation flap from colliding with the wall during an earthquake. At the same time, a horizontally rotatable swing plate is provided to cover the anti-stuck gap, and the seismic isolation flap is cooperated with to maintain the coverage of the seismic isolation joint while adapting to the displacement and deformation of the walls on both sides of the seismic isolation joint. This solves the problem of the conventional cover plate being easily damaged by the wall when it is located near the wall while providing the covering function of the conventional cover plate.

[0035] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0036] Please see attached Figure 1 and 4 The present invention provides a cover plate structure for a seismic isolation joint adjacent to a wall, which is used for covering a seismic isolation joint 2 between a ground foundation adjacent to a wall 1, and the cover plate structure comprises a seismic isolation flap 4 and a swing plate 6; the seismic isolation flap 4 is arranged above the seismic isolation joint 2, and an anti-stuck gap is left between the seismic isolation flap 4 and the wall 1 on one side thereof; the swing plate 6 covers the anti-stuck gap, and one end of the swing plate 6 is horizontally rotated near the wall 1 and connected to the top of the ground foundation on that side, and the other end of the swing plate 6 is erected on the top of the ground foundation on the other side; on the ground foundation The seismic isolation flap 4 connected to the conventional seismic isolation joint 2 is used as a cover in the horizontal direction, and an anti-stuck gap is reserved between the seismic isolation flap 4 near the wall 1 and the wall 1 to avoid the seismic isolation flap 4 from colliding with the wall 1 during an earthquake. At the same time, a horizontally rotatable swing plate 6 is provided to cover the anti-stuck gap, and the seismic isolation flap 4 is cooperated with to maintain the coverage of the seismic isolation joint 2 while adapting to the displacement and deformation of the walls 1 on both sides of the seismic isolation joint 2. In this way, the covering function of the conventional cover is provided while solving the problem that the conventional cover plate adjacent to the wall is prone to damage to the wall 1.

[0037] Furthermore, in order to lower the setting height of the seismic isolation flap 4 and the swing plate 6 to ensure the flatness of the ground while maintaining the coverage of the seismic isolation joint 2, a cover groove 3 is jointly opened on the ground foundation on both sides of the seismic isolation joint 2, and the seismic isolation flap 4 is set inside the cover groove 3.

[0038] For further information, please refer to the attached Figure 2-3 , and also includes a hinged support 8 and a wedge-shaped support 10; one end of the seismic isolation flap 4 is flipped inside the cover groove 3 and connected to the ground foundation on that side through the hinged support 8; the wedge-shaped support 10 is connected to the ground foundation on the other side inside the cover groove 3, and the top surface of the wedge-shaped support 10 cooperates with the inclined surface of the end surface of the seismic isolation flap 4; the hinged support 8 cooperates with the wedge-shaped support 10, so that the seismic isolation flap 4 can adapt to the changes of the seismic isolation joint 2 caused by earthquakes inside the cover groove 3, and complete the corresponding actions to maintain the coverage of the seismic isolation joint 2.

[0039] Furthermore, it also includes a sliding support 9, which is connected to the wedge-shaped support 10 on the ground foundation on one side inside the cover groove 3, and the sliding support 9 supports the seismic isolation flap 4; the sliding support 9 is provided to reduce the contact friction between the seismic isolation flap 4 and the cover groove 3, thereby increasing the automatic displacement adjustment efficiency of the seismic isolation flap 4 to adapt to the earthquake inside the cover groove 3.

[0040] Furthermore, it also includes a side seam cover plate 5, which is fixed to the top of one end of the seismic isolation flap 4 and the wedge-shaped support 10, and the side of the side seam cover plate 5 away from the seismic isolation flap 4 is attached to the top of the ground foundation on this side; the side seam cover plate 5 can cover the gap formed by the seismic isolation flap 4 and the top of the ground foundation, increase the flatness and aesthetics of the ground, and in order to avoid the problem of tripping caused by the side seam cover plate 5, the top edge of the side seam cover plate 5 is also chamfered.

[0041] Please continue to refer to the attached Figure 1-3 , a cover plate structure for the wall-adjacent area of ​​a seismic isolation joint, further comprising an adapter 7, one end of a swing plate 6 is rotatably connected to the top of the ground foundation on this side at a corner near the wall 1 through the adapter 7; the ground foundation on this side is the ground foundation on which the seismic isolation flap 4 is flipped and connected; setting the rotating connection side of the swing plate 6 to be on the same side as the flip connection side of the seismic isolation flap 4 can reduce the mutual influence between the swing plate 6 and the seismic isolation flap 4, better adapt to the earthquake to complete the corresponding position adjustment, and maintain full coverage of the seismic isolation joint 2;

[0042] Furthermore, the corner arc is processed, and the center of the arc is concentric with the adapter 7; the swing plate 6 is rotated to connect the corner arc processing to avoid collision with the wall 1 during rotation, thereby reducing the distance between the swing plate 6 and the wall 1 and increasing the coverage area of ​​the plane seismic isolation joint 2;

[0043] In order to avoid the problem of tripping caused by the swing plate 6, the top edge of the swing plate 6 is chamfered.

[0044] The seismic isolation flap 4 and the swing plate 6 cooperate with each other in the above structure to adapt to the changes of the seismic isolation joints in the wall area caused by earthquakes; for example, under normal working conditions, the seismic isolation joints 2 do not change, the seismic isolation joints 2 away from the wall 1 are normally covered by the seismic isolation flap 4, and the anti-stuck gap between the seismic isolation flap 4 and the wall 1 is normally covered by the swing plate 6;

[0045] When the width of the seismic isolation joint 2 decreases under the action of a single-direction horizontal earthquake force, the seismic isolation flap 4 away from the wall 1 is pushed along the sliding support 9 and tilted upward under the action of the wedge support 10, and the swing plate 6 normally covers the anti-stuck gap between the seismic isolation flap 4 and the wall 1, and will not damage the wall 1. After the seismic force disappears, the seismic isolation flap 4 and the swing plate 6 return to their initial state;

[0046] When the width of the seismic isolation joint 2 increases under the action of a single-direction horizontal earthquake force, the seismic isolation flap 4 away from the wall 1 is pulled along the sliding support 9, and the side seam cover 5 connected to its top maintains the coverage of the gap between the seismic isolation flap 4 and the ground foundation, and the swing plate 6 normally covers the anti-stuck gap between the seismic isolation flap 4 and the wall 1, and will not damage the wall 1. After the seismic force disappears, the seismic isolation flap 4 and the swing plate 6 return to their initial state;

[0047] The width of the seismic isolation joint 2 remains unchanged under the action of a unidirectional horizontal earthquake force in a plane, and when the ground foundations on both sides shift relative to each other along the flip direction of the swing plate 6, the seismic isolation flap 4 away from the box body 1 is adaptively shifted along the sliding support 9 to maintain its coverage of the seismic isolation joint 2 below, and the swing plate 6 will swing under the action of the wall 1 on the ground foundation on one side that is not rotated, while maintaining the coverage of a large area of ​​the dislocated gap without causing damage to the wall. After the seismic force disappears, the seismic isolation flap 4 returns to its initial state, while the swing plate 6 needs manual assistance to return to its initial state;

[0048] The width of the seismic isolation joint 2 remains unchanged under the action of a unidirectional horizontal earthquake force, and when the ground foundations on both sides shift relative to each other along the direction in which the swing plate 6 cannot flip, the seismic isolation flap 4 away from the box body 1 shifts adaptively along the sliding support 9 to maintain its coverage of the seismic isolation joint 2 below, while the swing plate 6 remains in position to maintain coverage of the larger area of ​​the dislocated gap. After the seismic force disappears, the seismic isolation flap 4 and the swing plate 6 return to their initial state;

[0049] Similarly, if the seismic isolation joint 2 is subjected to horizontal seismic forces in two directions on the plane, the seismic isolation flap 4 and the swing plate 6 simultaneously complete corresponding actions to maintain the coverage of the seismic isolation joint 2 without causing damage to the wall 1. To avoid the position conflict caused by the simultaneous action of the seismic isolation flap 4 and the swing plate 6, it is only necessary to set the side of the swing plate 6 away from the wall 1 to cover part of the seismic isolation flap 4.

[0050] The present invention is described in detail above in conjunction with the embodiments of the accompanying drawings. A person skilled in the art can make various variations of the present invention according to the above description. Therefore, certain details in the embodiments should not constitute a limitation of the present invention, and the scope of protection of the present invention shall be defined by the scope of the attached claims.
