Description

Technical Field

[0001] This utility model relates to the field of building structure technology, specifically to a basement side wall structure that is earthquake-resistant and crack-resistant. Background Technology

[0002] Earthquakes are extremely devastating natural disasters, causing property damage and casualties primarily due to building collapse. Therefore, designing and constructing earthquake-resistant buildings is a crucial task. Earthquake-resistant walls, as an important component of this, focus on mitigating the impact of earthquakes by increasing the building's seismic resistance. The design and construction of shear walls are not merely about preventing building collapse, but also about ensuring the building possesses good structural performance during an earthquake, thereby reducing damage and providing safety.

[0003] The side walls of the basement are located at the very edge of the basement and are in direct contact with the ground outside the basement. During an earthquake, they will directly face the lateral forces exerted by the ground affected by seismic waves, so they have higher requirements for seismic performance.

[0004] Therefore, a basement sidewall structure with enhanced seismic resistance is needed. Utility Model Content

[0005] In order to overcome the above-mentioned shortcomings of the prior art, the purpose of this utility model is to provide a basement sidewall structure with enhanced seismic performance.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A seismic and crack-resistant basement sidewall structure includes a sidewall panel, a basement floor, and a seismic damping and reinforcement device, wherein the bottom end of the sidewall panel is fixedly connected to the basement floor.

[0008] The shock absorption and reinforcement device includes a base and a support base. The base is fixedly installed on the bottom surface of the basement, and the support base is fixedly installed on the inner side surface of the side wall panel.

[0009] The base is provided with a first limiting groove and a first slider. The first limiting groove is horizontally arranged and perpendicular to the side wall plate. The first slider is limited and slidably arranged in the first limiting groove. The base is also provided with a supporting power source. The supporting power source is connected to the first slider in a transmission manner. The supporting power source is used to push the first slider to move towards the side wall plate to provide a supporting force for the side wall plate.

[0010] The support base is provided with a second limiting groove and a second slider, the second slider being slidably positioned within the second limiting groove; the second limiting groove is vertically positioned; a support spring is connected between the second slider and the end of the second limiting groove, the support spring being used to apply an elastic preload to the second slider to make it slide downward along the second limiting groove;

[0011] A support rod is connected between the first slider and the second slider. One end of the support rod is hinged to the first slider, and the other end of the support rod is hinged to the second slider.

[0012] By adopting the above technical solution, an elastic connection is added to the already rigid connection between the basement sidewalls and the floor, improving the seismic resistance of the wall structure. Specifically, this elastic connection involves the thrust from the first slider on the basement floor to the second slider via a support rod, which is then transmitted to the sidewalls through a support spring. Firstly, this generates a horizontal support force on the sidewalls from the basement floor, preventing the sidewalls from tilting into the basement during an earthquake. Secondly, due to the action of the support spring and the support power source, the support force generated by the basement floor on the sidewalls is adjustable, and the magnitude of the support force can be clearly seen from the compression of the support spring.

[0013] Specifically, the shock-absorbing reinforcement device can also be placed between the side wall panel and the basement ceiling. The specific principle of its supporting function is the same, and placing the reinforcement device between the side wall panel and the ceiling can prevent the reinforcement device from occupying ground space.

[0014] As an improvement, the supporting power source is a hydraulic cylinder, which pushes the first slider to move towards the side wall plate.

[0015] By adopting the above technical solution, the hydraulic cylinder generates thrust to support the side wall plate, which is structurally reliable, easy to maintain, and also allows for adjustment of the support force by adjusting the liquid pressure according to the actual situation.

[0016] As an improvement, the basement floor has a bottom groove, the base is embedded in the bottom groove, the top of the bottom groove has a bottom groove cover plate, and the bottom groove cover plate has a through groove that matches the support rod.

[0017] By adopting the above technical solution, the base is completely buried below the bottom of the basement, with only the support rods extending through the bottom trench cover to the side wall panels, thus reducing the space occupied by the shock absorption and reinforcement device on the basement floor.

[0018] As an improvement, the side wall panel is provided with a support groove, the support seat is embedded in the support groove, the opening of the support groove is provided with a decorative cover plate, and the decorative cover plate is provided with a through groove that matches the support rod.

[0019] By adopting the above technical solution, the support base is completely embedded inside the side wall panel, with only the support rod extending through the decorative cover plate to the bottom of the basement. This way, the support base will not protrude from the wall and encroach on the interior space, and the aesthetics are also better. In addition, the fact that the support base is completely embedded inside the side wall panel further enhances the stability of the support force.

[0020] As an improvement, a support plate is provided in the support groove, and the support plate is connected to the support base through several sets of buffer support members; the buffer support members include a telescopic rod and a buffer spring, the telescopic rod is arranged in a horizontal direction; one end of the telescopic rod is connected to the support plate, the other end of the telescopic rod is connected to the support base, and the buffer spring is sleeved on the telescopic rod.

[0021] By adopting the above technical solution, a lateral buffer mechanism is established between the support plate and the support seat on the side wall panel through the telescopic rod and the buffer spring, which can further reduce the vibration of the side wall panel in the horizontal direction during an earthquake.

[0022] As an improvement, the side wall panel is provided with support piles on the outer side, and a gap is left between the support piles and the side wall panel; within the gap, a shock-absorbing pad, a protective plate, and a crushed stone layer are sequentially arranged on the side wall panel in the direction of the support piles.

[0023] By adopting the above technical solution, an external shock-absorbing structure consisting of shock-absorbing pads, protective plates, and a layer of crushed stone is built outside the side wall panels. This structure can reduce the impact force of vibrations before it is transmitted to the side wall panels from the ground soil. It can also be used to cope with vibrations generated by subway operation near the basement.

[0024] As an improvement, a waterproof cloth coated with adhesive is also provided between the shock-absorbing pad and the protective plate.

[0025] By adopting the above technical solution, adding a waterproof layer to the outside of the basement can prevent water from directly penetrating the shock-absorbing pads and side wall panels, thereby increasing the service life of the basement side wall panels and the shock-absorbing mechanism inside the basement.

[0026] As an improvement, a blind drain pipe is buried at the bottom of the crushed stone layer.

[0027] By adopting the above technical solution, rainwater that seeps into the ground during rain will collect in the blind drain pipe through the gaps in the gravel layer and be quickly drained away from the side wall panel by the blind drain pipe. On the one hand, this can extend the service life of the adhesive waterproof cloth as much as possible in terms of waterproofing, and on the other hand, it also helps to maintain the stability of soil moisture near the side wall panel and reduce the weakening effect of water erosion on soil stability.

[0028] Compared with the prior art, the beneficial effects of this utility model are:

[0029] The basement's side walls and floor, already rigidly connected, are further reinforced with an elastic connection. Specifically, this elastic connection involves the thrust from the first slider on the basement floor's base, via a support rod, to the second slider, which is then transmitted to the side walls through support springs. Firstly, this creates a horizontal support force on the side walls from the basement floor, preventing them from tilting inwards during an earthquake. Secondly, due to the support springs and the power source, the support force generated by the basement floor on the side walls is adjustable, and its magnitude can be clearly observed by the compression of the support springs.

[0046] Implementation Case 1:

[0047] As attached Figure 1-6 As shown, a seismic and crack-resistant basement sidewall structure includes a sidewall panel 1, a basement bottom surface 2, and a shock-absorbing and reinforcing device 3. The bottom end of the sidewall panel 1 is fixedly connected to the basement bottom surface 2.

[0048] The shock absorption and reinforcement device 3 includes a base 4 and a support 5. The base 4 is fixedly installed on the bottom surface 2 of the basement, and the support 5 is fixedly installed on the inner side of the side wall panel 1.

[0049] The base 4 is provided with a first limiting groove 6 and a first slider 7. The first limiting groove 6 is horizontally arranged and perpendicular to the side wall plate 1. The first slider 7 is slidably arranged in the first limiting groove 6. The base 4 is also provided with a supporting power source. The supporting power source is connected to the first slider 7 in a transmission manner. The supporting power source is used to push the first slider 7 to move towards the side wall plate 1 to provide a supporting force for the side wall plate 1.

[0050] The support base 5 is provided with a second limiting groove 8 and a second slider 9. The second slider 9 is slidably disposed in the second limiting groove 8. The second limiting groove 8 is vertically disposed. A support spring 10 is connected between the second slider 9 and the end of the second limiting groove 8. The support spring is used to apply an elastic preload to the second slider 9 so that it slides downward along the second limiting groove 8.

[0051] A support rod 11 is provided between the first slider 7 and the second slider 9. One end of the support rod 11 is hinged to the first slider 7, and the other end of the support rod 11 is hinged to the second slider 9.

[0052] The basement's side wall panel 1 and bottom surface, already rigidly connected, are further reinforced with an elastic connection. Specifically, this elastic connection involves the first slider 7 on the basement floor 4, through the support rod 11, transmitting the thrust to the second slider 9, and then through the support spring 10 to the side wall panel 1. Firstly, this generates a horizontal supporting force on the side wall panel 1 from the basement floor 2, preventing the side wall panel 1 from tilting into the basement during an earthquake. Secondly, due to the support spring 10 and the supporting power source, the supporting force generated by the basement floor 2 on the side wall panel 1 is adjustable, and the magnitude of the support can be clearly seen from the compression of the support spring 10.

[0053] Alternatively, the shock-absorbing reinforcement device 3 can be placed between the side wall panel 1 and the basement ceiling. The specific principle of its supporting function is the same, and placing the reinforcement device between the side wall panel 1 and the ceiling can prevent the reinforcement device from occupying ground space.

[0054] The supporting power source is a hydraulic cylinder 12, which pushes the first slider 7 to move towards the side wall plate 1.

[0055] The side wall plate 1 is supported by thrust generated by the hydraulic cylinder 12. The structure is reliable, easy to maintain, and the magnitude of the support force can be adjusted by adjusting the liquid pressure according to the actual situation.

[0056] The basement bottom surface 2 is provided with a bottom surface groove 14, the base 4 is embedded in the bottom surface groove 14, the bottom surface groove 14 is provided with a bottom groove cover plate 13, and the bottom groove cover plate 13 is provided with a through groove that matches the support rod 11.

[0057] The base 4 is completely buried below the bottom surface 2 of the basement, with only the support rod 11 extending through the bottom cover plate 13 to the side wall plate 1, which reduces the space occupied by the shock absorption and reinforcement device 3 on the basement floor.

[0058] The side wall panel 1 is provided with a support groove 15, and the support seat 5 is embedded in the support groove 15.

[0059] The support base 5 is completely embedded inside the side wall panel 1, so that the support base 5 will not protrude from the wall and take up indoor space, and the appearance is better. In addition, the support base 5 is completely embedded inside the side wall panel 1, which further enhances the stability of the support force.

[0060] A support plate 16 is provided in the support groove 15. The support plate 16 is connected to the support base 5 through a number of buffer support members. The buffer support members include a telescopic rod 18 and a buffer spring 17. The telescopic rod 18 is arranged in a horizontal direction. One end of the telescopic rod 18 is connected to the support plate 16, and the other end of the telescopic rod 18 is connected to the support base 5. The buffer spring 17 is sleeved on the telescopic rod 18.

[0061] A lateral buffer mechanism is established between the support plate 16 on the side wall panel 1 and the support base 5 through the telescopic rod 18 and the buffer spring 17, which can further reduce the vibration of the side wall panel 1 in the horizontal direction during an earthquake.

[0062] The side wall panel 1 is provided with a support pile 19 on the outside, and a gap is left between the support pile 19 and the side wall panel 1; within the gap, a shock-absorbing pad 20, a protective plate 21, and a crushed stone layer 22 are arranged sequentially on the side wall panel 1 in the direction of the support pile 19.

[0063] An external shock-absorbing structure consisting of a shock-absorbing pad 20, a protective plate 21, and a gravel layer 22 is constructed outside the side wall panel 1. This structure can reduce the impact force of vibrations before it is transmitted to the side wall panel 1 from the ground soil. It can also be used to cope with vibrations generated by subway operation near the basement.

[0064] A waterproof cloth 23 coated with adhesive is also provided between the shock-absorbing pad 20 and the protective plate 21.

[0065] Adding a waterproof layer to the outside of the basement can prevent moisture from directly penetrating the shock-absorbing pad 20 and the side wall panel 1, thereby increasing the service life of the basement side wall panel 1 and the shock-absorbing mechanism inside the basement.

[0066] A blind drain pipe 24 is buried at the bottom of the crushed stone layer 22.

[0067] When it rains, the water that seeps into the ground will collect in the blind drain pipe 24 through the gaps in the gravel layer 22, and will be quickly drained away from the side wall panel 1 by the blind drain pipe 24. On the one hand, this can extend the service life of the adhesive waterproof cloth 23 as much as possible in terms of waterproofing, and on the other hand, it can help maintain the stability of the soil moisture near the side wall panel 1 and reduce the weakening effect of water erosion on soil stability.
