Description

Technical Field

[0001] The present invention belongs to the technical field of building structures, and particularly relates to a steel-wood-concrete composite shear wall with replaceable coupling beams and wall-foot components. Background Art

[0002] Shear walls are important lateral force resisting components in high-rise and super high-rise buildings. Under large earthquake actions, traditional reinforced concrete shear walls often suffer serious damages such as the penetration of diagonal cracks in coupling beams and the crushing of concrete at the wall feet, and it is difficult to repair them after the earthquake. This will seriously affect people's normal life and cause huge economic losses.

[0003] To solve the above technical problems, shear walls with replaceable components can be designed. When the shear wall is damaged by an earthquake, the damaged parts can be replaced in time after the earthquake, so that the structural function can be quickly restored and the economic losses can be greatly reduced.

[0004] In the prior art, shear walls with replaceable components include: the main body part of the shear wall and a single replaceable coupling beam or a single replaceable wall-foot component shear wall, and dampers are arranged therein.

[0005] The deficiencies of the prior art are as follows:

[0006] (1) Since dampers are arranged therein, the structural stiffness and bearing capacity will be reduced.

[0007] (2) The main body part of the existing shear wall with replaceable components is still a reinforced concrete structure, and the applicable height is limited. In China, super high-rise buildings are in a period of vigorous development, and the damage of their structural and non-structural components will make it difficult to quickly restore the normal functions of buildings after an earthquake. This will not only cause huge economic losses, but also have a great negative impact on the social stability, normal production and life of the community where the super high-rise building is located after the earthquake, and even the city.

[0036] To make the above objects, features and advantages of the present invention more obvious and understandable, the following will describe the detailed implementation manners of the present invention in conjunction with the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific implementations disclosed below.

[0037] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "connected" and "connected to" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection, it can be directly connected, or indirectly connected through an intermediate medium, it can be the communication inside two components, or a "transmission connection", that is, power connection is carried out in various suitable ways such as belt drive, gear drive or sprocket drive. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] The following will further describe a steel-wood-concrete composite shear wall with replaceable coupling beams and wall footing components of the present invention in conjunction with the attached Figures 1-6 drawings.

[0039] Please refer to the attached Figures 1-3 drawings for emphasis. A steel-wood-concrete composite shear wall with replaceable coupling beams and wall footing components includes two groups of shear wall components 1 arranged at intervals and a replaceable coupling beam 2 connected between the two groups of shear wall components 1 and detachably connected to each of them. The shear wall component 1 includes a multi-chamber steel tube concrete wall body 11 and restraint edge members 12 respectively arranged on both sides of the multi-chamber steel tube concrete wall body 11. The multi-chamber steel tube concrete wall body 11 includes two outer steel plates 111 respectively connected to the two sets of restraint edge members 12. The two outer steel plates 111 and the two sets of restraint edge members 12 jointly enclose a concrete pouring cavity. The multi-chamber steel tube concrete wall body 11 further includes a partition plate 112 connecting the two outer steel plates 111 inside and dividing the concrete pouring cavity into a plurality of partition cavities 110. Concrete is poured into the partition cavities 110 to form an inner wall body 113. The restraint edge member 12 includes an outer restraint frame 121 made of steel plates. A restraint member insert cavity 120 is provided inside the outer restraint frame 121. The restraint edge member 12 further includes a restraint member insert block 122 embedded in the restraint member insert cavity 120. The restraint member insert block 122 is a wooden block. The restraint edge member 12 is made of H-shaped steel, and shear studs are provided on its inner flange to increase the connection with the concrete.

[0040] In this embodiment, the shear wall assembly 1 includes a multi-chamber steel tube concrete wall body 11 and restraint edge members 12 respectively arranged on both sides of the multi-chamber steel tube concrete wall body 11. Among them: The restraint edge member 12 is composed of steel and wood, that is, an outer restraint frame 121 made of steel plates and a square timber (restraint member insert block 122) embedded in the restraint member insert cavity 120 of the outer restraint frame 121. After an earthquake occurs, if damage occurs at the wall foot part (the bottom of the restraint edge member 12), the outer restraint frame 121 at the damaged part can be cut, new profiled steel can be welded in, the profiled steel at the damaged part can be replaced, and then square timbers can be filled in. When the restraint member insert block 122 is damaged by compression, it can also be replaced in time to quickly restore its function. And in this embodiment, the multi-chamber steel tube concrete wall body 11 is not a pure concrete structure. Its structure is: the inner wall body 113 is formed by pouring concrete, and the outer part of the inner wall body 113 is covered with an outer steel plate 111 and the outer restraint frame 121, which can meet the requirements of super high-rise buildings. The outer restraint frame 121 is also made of profiled steel. The outer steel plate and the H-shaped steel can effectively restrain the internal concrete and jointly resist the axial pressure with the concrete, thereby effectively increasing the applicable height of the shear wall. Therefore, after the steel-wood-concrete composite shear wall with replaceable coupling beams and wall foot components of the present invention adopts this structure, the formed shear wall assembly 1 can meet the requirements of super high-rise buildings. It well meets the requirements of the booming development of super high-rise buildings in our country.

[0041] In this embodiment, for the steel-wood-concrete composite shear wall with replaceable coupling beams and wall foot components of the present invention, the three materials of steel, wood and concrete are organically combined. While ensuring the structural strength and stiffness, the structural self-weight is reduced and the seismic response is reduced. After damage occurs at the wall foot parts of the replaceable coupling beam 2, the connection assembly 3 and the shear wall assembly 1, they can all be replaced in time to quickly restore their functions.

[0042] According to the specific embodiment of the present invention, the outer restraint frame 121 is made of H-shaped steel. There are two restraint member insert cavities 120, and one restraint member insert block 122 is arranged in each restraint member insert cavity 120. The two restraint member insert blocks 122 are connected to the outer restraint frame 121 through a threaded connector 4. In this embodiment, the outer restraint frame 121 is an H-shaped steel, and this structure is conducive to forming. The required length can be directly obtained by purchasing H-shaped steel and cutting it. The two receiving grooves in the H-shaped steel can be directly used as the restraint member insert cavities 120. Specifically, when implementing, bolt holes are opened in the web of the H-shaped steel, and the two restraint member insert blocks 122 are respectively filled into the restraint member insert cavities 120 of the H-shaped steel and are connected by bolts, which is convenient for installation and is also conducive to subsequent damage replacement.

[0043] According to a specific embodiment of the present invention, the multi-chamber concrete-filled steel tube wall 11 further includes shear studs 114. One end of each shear stud 114 is fixed to the outer steel plate 111, and the other end of each shear stud 114 extends into the inner wall 113. By connecting the outer steel plate 111 and the inner wall 113 with the shear studs 114, the bond between the concrete and the steel can be effectively increased, and their cooperative working performance can be enhanced.

[0044] According to a specific embodiment of the present invention, the replaceable coupling beam 2 includes an "L"-shaped first cover plate 21 and an "L"-shaped second cover plate 22. The first cover plate 21 and the second cover plate 22 are reversely buckled and jointly enclose a coupling beam insert cavity 20. A coupling beam insert block 23 is arranged in the coupling beam insert cavity 20. The first cover plate 21, the second cover plate 22 and the coupling beam insert block 23 are connected by threaded connectors 4. The first cover plate 21 and the second cover plate 22 are made of steel, and the coupling beam insert block 23 is made of wood. In this embodiment, the replaceable coupling beam 2 is composed of steel and wood. With the steel-wood combined structure, the self-weight of the structure can be reduced while ensuring the structural strength and stiffness, thereby reducing the seismic response. Specifically, the cross-section of the outer steel of the replaceable coupling beam (the first cover plate 21 and the second cover plate 22) is L-shaped. The first cover plate 21 and the second cover plate 22 are reversely buckled and jointly enclose the coupling beam insert cavity 20. The wooden coupling beam insert block 23 is received in the coupling beam insert cavity 20. This structure is convenient to assemble, and it is beneficial to replace the locally damaged components after damage.

[0045] Please refer to Figure 5 , according to a specific embodiment of the present invention, the partition plate 112 is provided with openings 1121 communicating with adjacent partition cavities 110. In this embodiment, by opening the openings 1121 in the partition plate 112, on the one hand, materials can be saved, and on the other hand, the reliability of the bond between the concrete and the steel plate can be enhanced.

[0046] According to a specific embodiment of the present invention, the number of the replaceable coupling beams 2 is multiple sets, and the multiple sets of replaceable coupling beams 2 are arranged at intervals along the height direction of the shear wall assembly 1. This structure is beneficial to realize the stable connection between two groups of shear wall assemblies 1. At the same time, it is beneficial to repair a single damaged replaceable coupling beam 2.

[0047] According to the specific embodiments of the present invention, the replaceable coupling beam 2 is integrally square, and a set of connection components 3 are provided at the four corners of each set of replaceable coupling beams 2. The connection components 3 include connection angle steels, and the connection angle steels include a first connecting plate 31 and a second connecting plate 32 vertically extending from one end of the first connecting plate 31. The first connecting plate 31 is connected to the shear wall assembly 1 through a threaded connecting member 4, and the second connecting plate 32 is connected to the replaceable coupling beam 2 through a threaded connecting member 4. In this embodiment, the first connecting plate 31 and the second connecting plate 32 of the connection angle steel are in a mutually perpendicular direction, which is used to realize the connection between the replaceable coupling beam 2 and the shear wall assembly 1. Through this structure, not only can the stable connection between the replaceable coupling beam 2 and the shear wall assembly 1 be realized, but also a detachable connection structure is formed by using the threaded connecting member 4, which further facilitates the repair of a single damaged replaceable coupling beam 2 and improves the repair efficiency.

[0048] Please refer to Figure 4 , according to the specific embodiments of the present invention, a reinforcing block 123 protruding into the partition cavity 110 is provided on the panel of the outer restraint frame 121 connected to the first connecting plate 31. In this embodiment, the reinforcing block 123 is mainly to ensure sufficient thread length, and stiffening ribs are provided near the reinforcing block 123 to increase the stiffness of this part. At the same time, the steel reinforcing block 123 can act together with the wooden restraint insert block 122 to increase the stiffness of the restraint edge member 12.

[0049] Please refer to Figure 6 , according to the specific embodiments of the present invention, the connection component 3 further includes a first web 33 and a second web 34 respectively provided at both ends of the connection angle steel, and weight-reducing holes 331 are provided on the first web 33 and the second web 34. The first web 33 and the second web 34 can increase the structural stiffness, but in order to prevent the stiffness of the connection component 3 from being too high to ensure that it fails prior to the reinforcing block, weight-reducing holes 331 are opened to weaken its stiffness. At the same time, the weight-reducing hole 331 structure can save the material consumption.

[0050] According to the specific embodiments of the present invention, the restraint insert cavity 120 is square. This structure is conducive to forming.

[0051] It should be noted that the threaded connecting member 4 in the present invention can be a screw or a bolt-nut structure or a structure of a lengthened screw with a nut. During specific implementation, it can be reasonably selected according to the working conditions of the to-be-connected member.

[0052] The steel-wood concrete composite shear wall with replaceable coupling beams and wall footing components of the present invention further includes a replaceable wall footing component 5, which includes a wall footing restraint frame 51 and a wall footing restraint insert 52. The wall footing restraint frame 51 includes a wall footing flange plate 511 and a wall footing web plate 512 that together form a "T" shape. The lower parts of the wall footing flange plate 511 and the wall footing web plate 512 are flush, and the upper part of the wall footing web plate 512 is lower than the upper part of the wall footing flange plate 511. The wall footing restraint insert 52 is a wooden square and is fixed to both sides of the wall footing web plate 512 through threaded connectors. The wall footing restraint insert 52 is cut from a T-shaped steel.

[0053] After an earthquake occurs, if damage occurs at the wall footing part (the bottom of the confinement edge member 12), the outer restraint frame 121 at the damaged part can be cut. Since the outer restraint frame 121 is an H-shaped steel, the flange of the H-shaped steel connected to the multi-chamber steel-concrete composite wall body 11 cannot be easily cut off. Therefore, the flange of the H-shaped steel connected to the multi-chamber steel-concrete composite wall body 11 is retained, and the lower part of the other flange and the lower part of the web of the H-shaped steel are cut off. When cutting, flush cutting should be avoided, but the cutting length of the flange should be greater than the cutting length of the web, so that a stepped cut groove is formed at the lower part of the outer restraint frame 121. This structure is beneficial to improving the connection stability of the replaceable wall footing component 5.

[0054] After cutting off the damaged part, weld the wall footing restraint frame 51 made of T-shaped steel. Since the lower parts of the wall footing flange plate 511 and the wall footing web plate 512 are flush, and the upper part of the wall footing web plate 512 is lower than the upper part of the wall footing flange plate 511, that is, the wall footing restraint frame 51 has a card slot matching the stepped cut groove at the lower part of the outer restraint frame 121. Align the wall footing flange plate 511 of the restraint frame with the lower cut-off flange of the H-shaped steel, align the wall footing web plate 512 with the lower cut-off web of the H-shaped steel, and weld and fix them. When welding, it includes four welds, specifically: the first weld is between the wall footing flange plate 511 and the lower cut-off flange of the H-shaped steel, the second weld is between the wall footing web plate 512 and the lower cut-off web of the H-shaped steel, the fourth weld is between the wall footing web plate 512 and the flange of the H-shaped steel connected to the multi-chamber steel-concrete composite wall body 11. The fourth weld is between the wall footing flange plate 511 and the side contact surface of the H-shaped steel. The four welds do not cross each other. After welding is completed, fill in the wall footing restraint insert 52. The wall footing restraint insert 52 is a replacement wooden square used to replace the original damaged wooden square. The height of the replacement wooden square is greater than the wall footing flange plate 511 (T-shaped steel flange), and the two are connected by bolts. The replacement wooden square is also connected to the original H-shaped steel web by bolts.

[0055] Compared with the prior art, the steel-wood-concrete composite shear wall of the present invention with replaceable coupling beams and wall footing components can quickly recover its function after an earthquake, has high stiffness, high strength, low maintenance cost, and is applicable to shear walls with large heights. The present invention provides a steel-wood-concrete composite shear wall with replaceable coupling beams and wall footing components, which organically combines three materials of steel, wood and concrete, reduces the structural self-weight while ensuring the structural strength and stiffness, and reduces the seismic response. When damage occurs to the replaceable coupling beams, connection components and wall footing parts of the shear wall components, they can be replaced in time to quickly restore the function. The weight-reducing holes in the connection components can not only save materials, but also appropriately weaken the connection components, making them fail prior to the H-shaped steel, thereby playing a protective role for it. After damage occurs to the wall footing part, the damaged part is cut off and the replaceable wall footing component is quickly installed to complete the rapid repair of the wall footing part.

[0056] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations fall within the scope defined by the appended claims.
