Description

Technical Field

[0001] The present application relates to the field of construction engineering, and particularly to a seismic shear wall for a subway superstructure. Background Art

[0002] A subway superstructure takes the subway as the core, and subway supporting facilities are constructed in its upper space for multi-level development and construction such as commerce, office, and residence. It promotes urban development with rail transit as the guide and provides supporting services for the city around the subway.

[0003] The shear wall of a residential project is a wall used to resist the bending effect of wind force and seismic shear waves on the building body. The shear wall includes an internal skeleton and a concrete wall cast outside the internal skeleton. In order to reduce the seismic feeling generated by subway operation, the shear wall of a residential project usually needs to have high seismic resistance.

[0004] Generally speaking, the residential project on the subway superstructure from bottom to top is as follows: a commercial vehicle garage floor (i.e., the first basement floor) located above the subway garage, a seismic isolation conversion damping interlayer, and an above-ground residential floor. However, usually, the subway garage is contracted by a municipal unit for construction, while the residential project is often contracted by a construction company for construction. The construction plans of the two are not unified, and the residential project is usually constructed by another construction unit after a period of time when the subway garage construction is completed. At this time, the concrete has been completely poured, and the position of the reserved connecting piece cannot be adjusted anymore; especially when the perpendicularity of the shear wall of the subway garage and the shear wall of the residential project does not meet the requirements, how to construct to ensure that the shear wall of the residential project and the shear wall of the subway garage meet the perpendicularity requirements, so that the shear wall obtains better seismic performance, is an urgent problem to be solved. Summary of the Invention

[0005] In order to make the shear wall of the residential project and the shear wall of the subway garage meet the perpendicularity requirements and make the shear wall obtain better seismic performance, the present application provides a seismic shear wall for a subway superstructure.

[0006] A seismic shear wall for a subway superstructure provided by the present application adopts the following technical solutions:

[0007] It includes a basement layer, a damping interlayer, and an above-ground layer arranged in sequence from bottom to top;

[0008] The internal skeleton of the basement layer includes a first damping steel plate; the internal skeleton of the damping interlayer includes a second damping steel plate, and the internal skeleton of the above-ground layer includes a third damping steel plate;

[0009] The first damping steel plate includes a support portion located in the basement layer and a connection portion extending to the damping interlayer, wherein the support portion is fixed to the subway superstructure using anchor bolts;

[0010] When the offset size between the first shock-absorbing steel plate and the third shock-absorbing steel plate is greater than 100 mm, the second shock-absorbing steel plate is anchored between the connecting part and the third shock-absorbing steel plate using anchors, and a conversion beam for increasing the supporting area is fixed to the top end of the second shock-absorbing steel plate, and the third shock-absorbing steel plate is fixed to the conversion beam using anchors.

[0011] By adopting the above technical solution, the first shock-absorbing steel plate of the underground layer is fixed to the subway cover by anchors, which is convenient for fixing to the subway cover under the premise that no connecting steel plate is reserved in the subway garage; when the offset size of the shear wall of the local upper layer and the shear wall of the underground layer is greater than 100mm, the position of the second shock-absorbing steel plate is changed, and the second shock-absorbing steel plate is replaced by fixing it on the cover of the underground layer instead of the conventional connection with the connection part, and the second shock-absorbing steel plate is fixed between the first shock-absorbing steel plate and the third shock-absorbing steel plate, so as to realize the transition of the position of the underground shear wall and the ground shear wall in the shock-absorbing interlayer, and utilize the conversion beam arranged on the top of the second shock-absorbing steel plate to provide an installation base for fixing the first shock-absorbing steel plate, thereby meeting the installation position requirement of the first shock-absorbing steel plate, realizing a smooth transition from the underground shear wall to the ground shear wall, and meeting the construction requirement of the verticality of the three-layer shear wall.

[0012] Optionally, when the offset size between the first shock-absorbing steel plate and the third shock-absorbing steel plate is less than 100 mm, the second shock-absorbing steel plate is fixed to the connecting part, and the side of the second shock-absorbing steel plate away from the connecting part is thickened with a concrete component so that the shear wall of the shock-absorbing interlayer is widened, and the third shock-absorbing steel plate is fixed to the concrete component using an anchor.

[0013] By adopting the above technical solution, when the offset size is small, the method of directly increasing the thickness of the concrete section is used, so that the third shock-absorbing steel plate can be anchored on the newly added concrete component, facilitating construction while ensuring the seismic effect of the sandwich shear wall.

[0014] Optionally, the anchor is a chemical anchor.

[0015] By adopting the above technical solution, the chemical anchor bolts themselves have excellent properties such as high strength, good seismic resistance, high temperature resistance, acid and alkali resistance, etc., which can make the shear wall have higher seismic resistance.

[0016] Optionally, the internal skeletons of the underground layer, the shock-absorbing interlayer and the above-ground layer all include wall bars, and the first shock-absorbing steel plate, the second shock-absorbing steel plate, the third shock-absorbing steel plate and the wall bars are connected with tie components for increasing the connection force with concrete.

[0017] By adopting the above technical solution, the setting of the tie component can increase the contact area between the first shock-absorbing steel plate, the second shock-absorbing steel plate, the third shock-absorbing steel plate and the concrete during the pouring of concrete, thereby increasing the connection force with the solidified concrete and reducing the phenomenon that the shear wall splits from both sides of the shock-absorbing steel plate.

[0018] Optionally, the tie component includes a fixing seat connected to the outside of the first shock-absorbing steel plate and a plurality of hook members mounted on the fixing seat for hooking the wall reinforcement. The hook member includes a hook-shaped hooking section and a straight connecting section. The connecting section is passed through the fixing seat and fixed by a locking member, and the hooking section is hooked on the wall reinforcement.

[0019] By adopting the above technical solution, the hook member is passed through the fixing seat and the relative position between the hook member and the fixing seat is fixed by a locking member, which is convenient to operate during connection, saves the construction time of construction workers, improves the construction efficiency, and reduces the labor intensity of construction workers.

[0020] Optionally, the fixing seat includes a fixing steel plate welded to the first shock-absorbing steel plate and a connecting steel plate welded to the fixing steel plate. A plurality of the connecting steel plates are arranged at intervals along the length direction of the fixing steel plate;

[0021] The locking member is a high-strength locking nut, and an external thread matched with the high-strength locking nut is processed on the connecting section.

[0022] By adopting the above technical solution, using a high-strength locking nut as the locking member can improve the connection stiffness between the hook member and the connecting steel plate.

[0023] Optionally, an oblong hole with an extending direction perpendicular to the fixing steel plate is formed in the connecting steel plate, and the tie component further includes a limiting member (44) for limiting the position of the hook member (42).

[0024] By adopting the above technical solution, the oblong hole with an extending direction perpendicular to the fixing steel plate can adjust the installation position of the hook member to adapt to the working conditions with different distances between the shock-absorbing steel plate and the wall reinforcement. The limiting member can reduce the probability that the hook member shakes in the oblong hole, thereby causing the hook member to fall off from the wall reinforcement.

[0025] Optionally, the limiting member includes a connecting sleeve sleeved on the hook member, a fastener fixed on the connecting sleeve, and a locking sleeve for synchronously locking the connecting sleeve and the hook member. A limiting buckle seat matched with the fastener is fixed on one side of the connecting steel plate away from the locking member. A plurality of groups of the limiting buckle seats are provided, and the plurality of groups of limiting buckle seats are perpendicular to the axis of the oblong hole and are arranged at intervals along the length direction of the oblong hole.

[0026] By adopting the above technical solution, during installation, the fastener is buckled on a corresponding set of limit buckle seats, and the locking sleeve is screwed to fix the relative positions of the connecting sleeve and the hook member, restricting the movement of the hook member along the axis direction of the oval hole.

[0027] Optionally, the inner wall of the connecting sleeve is machined with an internal thread, the outer wall of the locking sleeve is machined with a first external thread that mates with the internal thread of the connecting sleeve, and the inner wall of the locking sleeve is machined with a second internal thread that mates with the external thread of the connecting section.

[0028] By adopting the above technical solution, an internal thread is machined on the inner wall of the connecting sleeve, an external thread is machined at the corresponding position of the hook member, and the locking sleeve is in threaded fit with both the connecting sleeve and the hook member. As the locking sleeve is gradually screwed, the locking sleeve gradually extends into the connecting sleeve and mates with the internal thread of the connecting sleeve, realizing the fixation of the position of the connecting sleeve on the connecting section.

[0029] Optionally, the tie component includes a number of connection nodes welded on both sides of the first shock-absorbing steel plate, and the connection nodes are hooked and connected to the wall reinforcement in the form of hooks.

[0030] By adopting the above technical solution, after the construction of the wall reinforcement is completed, the wall reinforcement and the shock-absorbing steel plate are pulled by manually welding the connection nodes in sequence. Although the welding is relatively cumbersome, it can ensure the pulling strength of the connection nodes.

[0031] In summary, the present application includes at least one of the following beneficial technical effects:

[0032] 1. In the present application, by using the anchor, the first shock-absorbing steel plate in the underground layer is anchored in the concrete of the subway superstructure and fixed with the reserved parts, realizing the reliable connection of the first shock-absorbing steel plate. At the same time, the steel plate has the characteristics of light weight and high strength, making the shear wall have strong shock-absorbing performance. When the perpendicularity deviation between the first shock-absorbing steel plate and the third shock-absorbing steel plate is large, by changing the position of the second shock-absorbing steel plate in the shock-absorbing interlayer and installing a conversion beam for fixing the third shock-absorbing steel plate at the top of the second shock-absorbing steel plate, a gradual transition of perpendicularity is achieved in the shock-absorbing interlayer, enabling the perpendicularity of the three-layer shear wall to meet the construction requirements, and the construction is convenient, making the disturbance of the subway passage to the upper layer smaller;

[0033] 2. By fixing the hook member and the connecting steel plate with high-strength locking nuts, on the basis of ensuring the connection strength, the installation of the hook member is facilitated;

[0034] 3. Through the setting of the oval hole, when the distance between the shock-absorbing steel plate and the wall reinforcement is different, the hook member can always maintain the pulling of the shock-absorbing steel plate and the wall reinforcement, which is convenient for adjustment; the setting of the limiting member is convenient for reducing the probability of the hook member shaking and avoiding the movement of the hook member along the axis direction of the oval hole.

Detailed implementation manners

[0041] The following further describes the present application in detail with reference to the attached Figures 1-5 drawings.

[0042] The embodiment of the present application discloses an anti-seismic shear wall for a subway upper cover. Referring to Figure 1 and Figure 2 , the anti-seismic shear wall of the present application is divided into three layers, which are the basement layer 1, the shock-absorbing interlayer 2 and the above-ground layer 3 in sequence from bottom to top.

[0043] Referring to Figure 1 and Figure 2 , the internal skeleton of the present application includes shock-absorbing steel plates and wall reinforcements 5 surrounding the shock-absorbing steel plates. Specifically, the internal skeleton of the basement layer 1 includes a first shock-absorbing steel plate 11; the internal skeleton of the shock-absorbing interlayer 2 includes a second shock-absorbing steel plate 21; the internal skeleton of the above-ground layer 3 includes a third shock-absorbing steel plate 31.

[0044] The first shock-absorbing steel plate 11 includes a supporting portion 111 located in the underground layer 1 and a connecting portion 112 extending to the shock-absorbing interlayer 2. The supporting portion 111 is fixed to the subway upper cover using anchor bolts 6 and is welded and fixed to the reserved connecting member of the subway upper cover. This is to achieve the fixation of the first shock-absorbing steel plate 11 in the underground layer 1 when the perpendicularity requirements are not met between the subway upper cover 7 and the predetermined construction position of the residential project.

[0045] Generally speaking, when there is no offset between the shear walls of the underground layer 1 and the above-ground layer 3, that is, when the actual fixation position of the first shock-absorbing steel plate 11 and the predetermined installation position of the third shock-absorbing steel plate 31 are exactly in the same vertical plane, the perpendicularity meets the requirements. At this time, the second shock-absorbing steel plate 21 is welded and fixed to the connecting portion 112, and the top of the second shock-absorbing steel plate 21 also extends to the above-ground layer 3 to form a reserved connecting section for welding and fixing with the third shock-absorbing steel plate 31.

[0046] When the perpendicularity deviation of the shear walls of the underground layer 1 and the above-ground layer 3 is small, that is, when the offset dimension between the first shock-absorbing steel plate 11 and the third shock-absorbing steel plate 31 is less than 100 mm, the second shock-absorbing steel plate 21 is fixed to the connecting portion 112. A concrete member (not shown in the figure) is thickened on the side of the second shock-absorbing steel plate 21 facing away from the connecting portion 112, making the shear wall of the shock-absorbing interlayer 2 wider. The third shock-absorbing steel plate 31 is fixed to the concrete member using anchor bolts 6. Since the shock-absorbing interlayer 2 is not used for residential purposes, by thickening the wall thickness of the shear wall of the shock-absorbing interlayer 2, the thickened part of the wall thickness can be used as a support base for fixing the third shock-absorbing steel plate 31, actively creating a fixing position for the third shock-absorbing steel plate 31 and meeting the perpendicularity requirements of the shear wall of the residential project.

[0047] When the perpendicularity deviation of the shear walls of the underground layer 1 and the above-ground layer 3 is large, that is, when the offset dimension between the first shock-absorbing steel plate 11 and the third shock-absorbing steel plate 31 is greater than 100 mm, the second shock-absorbing steel plate 21 is anchored between the connecting portion 112 and the third shock-absorbing steel plate 31 using anchor bolts 6. A transfer beam 22 for increasing the bearing area is fixed to the top of the second shock-absorbing steel plate 21, and the third shock-absorbing steel plate 31 is fixed to the transfer beam 22 using anchor bolts 6. By moving the fixing position of the second shock-absorbing steel plate 21, a smooth transition of the installation positions of the first shock-absorbing steel plate 11 and the third shock-absorbing steel plate 31 is achieved. On the premise of ensuring the installation stability of the third shock-absorbing steel plate 31, the perpendicularity of the shear walls of the underground layer 1, the shock-absorbing interlayer 2, and the above-ground layer 3 all meets the requirements.

[0048] Refer to Figure 2, the anchor of the present application 6 uses chemical anchor bolts 61, and the anchoring depth of the chemical anchor bolts 61 is about 20 cm. The chemical anchor bolts 61 themselves have excellent characteristics such as high strength, good seismic resistance, aging resistance, acid and alkali resistance, and low temperature resistance. Therefore, the fixing of the first shock-absorbing steel plate 11, the second shock-absorbing steel plate 21, and the third shock-absorbing steel plate 31 on the concrete upper cover has higher connection strength and better seismic resistance.

[0049] To reduce the probability of concrete splitting, a tie component 4 for increasing the connection force with the concrete is connected between the first shock-absorbing steel plate 11, the second shock-absorbing steel plate 21, the third shock-absorbing steel plate 31 and the wall reinforcement 5. The tie component 4 is used to respectively realize the pulling of the two side wall reinforcements 5 by the first shock-absorbing steel plate 11, the second shock-absorbing steel plate 21, and the third shock-absorbing steel plate 31, so as to reduce the probability of the shock-absorbing steel plate separating from the concrete or the concrete cracking.

[0050] Refer to Figure 1 , in a specific structural embodiment, taking the tie component 4 outside the first shock-absorbing steel plate 11 as an example, the tie component 4 includes a number of connection nodes 45 welded on both sides of the first shock-absorbing steel plate 11, and the connection nodes 45 are hooked and connected to the wall reinforcement 5 in the form of hooks.

[0051] Refer to Figure 3 , in another specific structural embodiment, also taking the tie component 4 outside the shock-absorbing sandwich 2 as an example, the tie component 4 includes fixing seats 41 welded on both sides of the shock-absorbing sandwich 2 and a number of hook members 42 fixed on the fixing seats 41 for hooking and connecting with the wall reinforcement 5. The hook member 42 includes a hooking section 421 and a connecting section 422. The connecting section 422 is passed through the fixing seat 41 and fixed by a locking member 43, and the hooking section 421 is hooked on the wall reinforcement 5. When pulling, pass the connecting section 422 through the fixing seat 41, and make the hooking section 421 hook the wall reinforcement 5. Adjust the connection force between the hooking section 421 and the wall reinforcement 5, and lock it with the locking member 43 to fix the position of the hook member 42 at this time. Compared with the method of manually welding the connection nodes 45 in sequence, this fixing method is convenient for installation, saves the construction time of construction workers, and improves the construction efficiency.

[0052] Refer to Figure 3 and Figure 4 , specifically, the fixing seat 41 includes a fixing steel plate 411 welded on the shock-absorbing sandwich 2 and a connecting steel plate 412 welded on the fixing steel plate 411. A plurality of connecting steel plates 412 are arranged at intervals along the length direction of the fixing steel plate 411. To ensure the reliable connection between the hook member 42 and the connecting steel plate 412 and improve the pulling strength of the tie component 4, the locking member 43 of the present application uses a high-strength locking nut, and the connecting section 422 is processed with an external thread matching the high-strength locking nut.

[0053] Refer toFigure 4 , in order to adapt to the working conditions with different distances between the shock-absorbing interlayer 2 and the wall reinforcement 5, an oblong hole 4121 with an extending direction perpendicular to the fixed steel plate 411 is formed in the connecting steel plate 412, so as to facilitate the adjustment of the connection position of the hook member 42. The tying assembly 4 further includes a limiting member 44 for limiting the position of the hook member 42, so as to reduce the probability that the hook member 42 shakes and then causes the hook position between the hook member 42 and the wall reinforcement 5 to fall off.

[0054] Refer to Figure 4 and Figure 5 , the limiting member 44 includes a connecting sleeve 441 sleeved on the hook member 42, a fastener 443 fixed on the connecting sleeve 441, and a locking sleeve 442 for synchronously locking the connecting sleeve 441 and the hook member 42. A limiting buckle seat 444 cooperating with the fastener 443 is fixed on the side of the connecting steel plate 412 away from the locking member 43. There are several groups of the limiting buckle seats 444, and the several groups of limiting buckle seats 444 are perpendicular to the axis of the oblong hole 4121 and are arranged at intervals along the length direction of the oblong hole 4121. Internal threads are machined on the inner wall of the connecting sleeve 441, a first external thread 4421 matching the internal threads of the connecting sleeve 441 is machined on the outer wall of the locking sleeve 442, and a second internal thread 4422 matching the external threads of the connecting section 422 is machined on the inner wall of the locking sleeve 442. The locking sleeve 442 is threadedly connected to both the connecting sleeve 441 and the hook member 42. After determining the connection position of the hook member 42, the fastener 443 is engaged with the limiting buckle seat 444, and the locking sleeve 442 is screwed, so that the locking sleeve 442 synchronously locks the hook member 42 and the connecting sleeve 441, and restricts the hook member 42 from moving along the axis direction of the oblong hole 4121.

[0055] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
