Description

Technical Field

[0001] The present invention relates to the field of civil engineering, and particularly to a bolt-connected concrete sandwich insulation wall panel structure with energy-dissipating coupling beams. Background Art

[0002] In view of the phenomenon that the functions of a building cannot meet the requirements during its entire life cycle, or it cannot be effectively demolished after being damaged by an earthquake, resulting in a great waste of resources and environmental pollution, a bolt-connected precast concrete sandwich insulation wall panel building technology is proposed. This system is a fully precast building system. The precast wall panels are both load-bearing members and maintenance and partition members. The vertical joints between adjacent wall panels and the horizontal joints between upper and lower wall panels are all connected by dry bolts. The bolt joints adopt a steel plate splicing form, eliminating the need for on-site secondary concrete pouring, featuring fast construction speed, high construction quality, energy conservation and environmental protection. At the same time, the building structure is easy to install and disassemble, conforming to the future trend of component recycling and reuse, capable of reducing construction waste emissions and promoting the sustainable development of the construction industry.

[0003] However, in the existing bolt-connected precast concrete sandwich insulation wall panel structure, the wall piers at door openings and window openings are all connected by concrete coupling beams. Under the action of high-intensity seismic loads, the overall deformation of the bolt-connected precast concrete sandwich insulation wall panel building is relatively large, and the concrete hidden beams at the door and window opening wall panels are shear-cut and cracked, forming a plastic hinge region at the beam ends, with relatively serious damage and being irreparable or replaceable. As an energy-dissipating component that protects the main structure from strong earthquake damage, the damper has the advantages of good energy-dissipating performance, high economic efficiency, and replaceability after an earthquake, and is widely used in actual structural engineering. However, the existing energy-dissipating mechanisms of coupling beam dampers mostly involve the shear yielding of shear steel plates for energy dissipation, with relatively low energy-dissipating efficiency and poor stability.

[0004] Therefore, it is necessary to propose a bolt-connected concrete sandwich insulation wall panel structure with energy-dissipating coupling beams, which combines the characteristics of convenient installation, high energy-dissipating efficiency, and good stability, and applies this new type of damper to the bolt-connected precast concrete sandwich insulation wall panel building to reduce wall panel damage and improve the overall seismic toughness of the structure. Summary of the Invention

[0005] To solve the above problems, the present invention provides a bolt-connected concrete sandwich insulation wall panel structure with energy-dissipating coupling beams, which replaces the concrete coupling beams at all door and window openings on the conventional bolt-connected concrete sandwich insulation wall panels with an energy-dissipating coupling beam system, and introduces an arrangement method of strengthening tie members to improve the seismic performance and maintainability of the structure, achieve the effect of replaceable coupling beams, further protect the main structure from serious damage, and reduce the repair cost and time after an earthquake.

[0006] To achieve the above object, the technical solution of the present invention is as follows: A bolt-connected concrete sandwich thermal insulation wall panel structure with energy-dissipating coupling beams, comprising a plurality of bolt-connected sandwich thermal insulation wall panels and a plurality of energy-dissipating coupling beams. The plurality of energy-dissipating coupling beams are respectively located at the door openings and window openings of the bolt-connected sandwich thermal insulation wall panels. Connection blocks are provided at both ends of the energy-dissipating coupling beams. The connection blocks are respectively hinged to one end of the corresponding energy-dissipating coupling beam, and the connection blocks are fixedly connected to the corresponding bolt-connected sandwich thermal insulation wall panel through through bolts. The plurality of energy-dissipating coupling beams and the bolt-connected sandwich thermal insulation wall panels are bolt-connected into an integrated structure through a plurality of connection blocks; Each energy-dissipating coupling beam includes an upper connecting rod and a lower connecting rod, and a plurality of diagonal web members are provided between the upper connecting rod and the lower connecting rod. Each diagonal web member includes an upper joint, a lower joint and a hollow sleeve. The upper joint and the lower joint are respectively hinged to the bottom wall of the corresponding upper connecting rod and the top wall of the corresponding lower connecting rod. Both ends of the sleeve are slidably connected to the upper joint and the lower joint respectively, and an energy-dissipating component for generating strain energy through deformation to consume the externally input energy is provided in the sleeve.

[0007] The technical principle of the above solution is as follows: When encountering ground motion, the energy-dissipating coupling beam can convert the shear deformation generated in the plane into the axial deformation generated by the energy-dissipating component in the sleeve of the diagonal web member, avoiding the generation of shear stress and improving the overall stability of the structure; When the ground motion with high intensity occurs, the energy-dissipating component in the sleeve of the diagonal web member undergoes compressive yield, which can effectively dissipate part of the energy released by the earthquake and reduce the damage suffered by the main structure.

[0008] The beneficial effects of adopting the above solution are as follows: This solution involves a sandwich thermal insulation wall panel connected by bolts and an energy-dissipating coupling beam system, forming a systematic overall layout. The concrete coupling beams at the door openings and window openings in the conventional design are replaced by detachable and replaceable energy-dissipating coupling beams, thereby avoiding the shear failure of the concrete coupling beams under earthquake action. The diagonal web members in the energy-dissipating coupling beam serve as the first line of earthquake resistance defense, dissipating energy through compressive yield during an earthquake and can be quickly replaced after the earthquake, greatly improving the seismic toughness and recovery ability of the structure.

[0009] Furthermore, the sleeves are in a cross-shaped structure and have no contact with each other, and the axes of adjacent diagonal web members are skew lines in space.

[0010] Beneficial effects: The design of no contact between the sleeves avoids the mutual interference of adjacent diagonal web members during the stress process, reducing the additional stress and energy loss generated by friction, collision, etc. The cross-shaped design enables the diagonal web members to be arranged more compactly in space, improving the space utilization rate of the entire structure while maintaining good stability and load-bearing capacity.

[0011] Furthermore, the energy-consuming components all include an upper elastic section and a lower elastic section. The bottom end of the upper elastic section is fixedly connected to an upper plastic energy-consuming section, and the top end of the lower elastic section is fixedly connected to a lower plastic energy-consuming section. The bottom end of the upper plastic energy-consuming section and the top end of the lower plastic energy-consuming section are both fixedly connected to a main elastic section. The two main elastic sections are in mutual contact. The sleeve is provided with a penetrating positioning hole corresponding to the position where the two main elastic sections are in contact.

[0012] Beneficial effects: The main elastic section, as the core part of the energy-consuming component, converts the externally input energy into heat energy or other forms of energy and dissipates it through its internal energy-consuming mechanism. The fitting design of the upper elastic section and the top end of the main elastic section, as well as the welded connection of the lower elastic section and the bottom end of the main elastic section, ensure the effective transfer and dissipation of energy in the main elastic section. The upper elastic section and the lower elastic section are connected to the upper joint and the lower joint of the diagonal web member through a force transfer cylinder. This design enables the external load to be more evenly dispersed into the main elastic section through the force transfer cylinder and the core rod, improving the energy dispersion efficiency of the energy-consuming component and the overall stability of the structure.

[0013] Furthermore, elastic connecting sections are provided inside both the upper joint and the lower joint. One end of each connecting section is fixedly connected to the inner wall of the corresponding upper joint or lower joint, and the other ends of the two connecting sections are respectively fixedly connected to the upper elastic section and the lower elastic section.

[0014] Beneficial effects: The addition of the connecting sections enables the energy-consuming component to generate greater deformation when subjected to external forces, thereby absorbing and dissipating more energy. This design improves the energy dissipation efficiency of the energy-consuming component, enabling the structure to better absorb and disperse energy when subjected to dynamic loads and reducing the direct impact on the wall. The elastic restoring force of the connecting sections helps to maintain the stability of the structure. After being subjected to external forces, the connecting sections can assist the energy-consuming component to quickly return to its original state, thereby maintaining the overall stability and safety of the structure.

[0015] Furthermore, a number of tie members are provided at the top and side of the bolt-connected sandwich insulated wall panel. The bolt-connected sandwich insulated wall panel includes an inner leaf, a thermal insulation layer, and an outer leaf. The inner leaf, the thermal insulation layer, and the outer leaf are connected into an integral panel through a number of tie members.

[0016] Beneficial effects: The presence of the tie members makes the connection between the inner leaf and the outer leaf more firm. They penetrate the thermal insulation layer and are tightly embedded in the two wall panels, effectively transferring and dispersing the load, thereby improving the connection strength and stability of the entire wall panel structure. The design of the tie members optimizes the load transfer path in the wall panel structure. Under seismic action, the load can be more evenly transferred to the inner leaf and the outer leaf through the tie members, avoiding local damage caused by load concentration.

[0017] Furthermore, the connecting blocks are all in a 'C'-shaped structure, and both ends of the upper connecting rod and the lower connecting rod are respectively hinged to the side of the corresponding connecting block away from the bolt-connected sandwich insulated wall panel.

[0018] Beneficial effects: Replacing the concrete concealed beam of the bolt-connected prefabricated door and window wall panels with a steel truss energy-dissipating coupling beam can effectively reduce the size of the wall panel components and improve the convenience of transportation.

[0019] Furthermore, several tie members located at the connection blocks are arranged adjacent to each other in groups of two tie members, and the arrangement method of each group of tie members includes vertical tie members and inclined tie members. The vertical tie members are arranged at a 90° intersection with the insulation layer, and the inclined tie members are arranged at a 45° intersection with the insulation layer. The vertical tie members and the inclined tie members form a triangular arrangement.

[0020] Beneficial effects: By arranging the tie members in a triangular shape composed of vertical and inclined types, the stability of the wall panel structure in the horizontal and vertical directions can be significantly enhanced, which helps to resist seismic actions and ensure the safety of the building. The triangular arrangement of tie members can more effectively disperse and transfer loads. When subjected to external forces, the loads can be more evenly dispersed throughout the wall panel through the triangular structure formed by the tie members, thereby improving the load-bearing capacity of the wall panel.

[0021] Furthermore, the tie members all include an inner core layer and an outer cladding layer. The outer cladding layer is wrapped and fixedly connected to the outside of the inner core layer. The inner core layer is all scored steel wires, and the outer cladding layer is made of GFRP composite resin.

[0022] Beneficial effects: The scored steel wire is used as the inner core layer, and its surface is specially treated to form periodically changing indentations or protrusions. This structure can significantly improve the tensile strength of the steel wire. At the same time, the scoring can also increase the bonding force with the outer cladding layer of GFRP resin to ensure a firm connection between the two. GFRP resin, as the outer cladding layer, has excellent toughness and impact resistance. It can absorb and disperse the energy generated by external loads, thereby protecting the inner core layer of scored steel wire from direct impact and damage. When the composite structure of the tie member is stressed, the inner core layer of scored steel wire and the outer cladding layer of GFRP resin can jointly bear the load and achieve uniform stress distribution. This helps to reduce the stress concentration phenomenon and improve the overall stability and durability of the tie member.

[0023] Furthermore, both the upper connecting rod and the lower connecting rod are I-beams, and several reinforcing ribs are welded in the hollow parts of the upper connecting rod and the lower connecting rod.

[0024] Beneficial effects: The upper connecting rod and the lower connecting rod are designed as I-beams and are only used to connect the two side wall panels without participating in energy dissipation. Designing both the upper connecting rod and the lower connecting rod as I-beams can significantly improve the load-bearing capacity and stability of the connection part of the wall panel. Welding reinforcing ribs in the hollow part can further enhance the connection stiffness. The steel beam itself does not undergo flexural yielding, provides additional support, and also optimizes the connection stress distribution, reducing the risk of structural failure caused by concentrated stress.

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.

[0031] The following is a further detailed description through specific embodiments: Embodiment 1: As shown in the attached Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in the figure: A bolt - connected concrete sandwich thermal insulation wall panel structure with energy - dissipating coupling beams, including several bolt - connected sandwich thermal insulation wall panels 1 and several energy - dissipating coupling beams 2. The bottom foundation form of the bolt - connected sandwich thermal insulation wall panel 1 adopts strip foundation. Several energy - dissipating coupling beams 2 are respectively located at the door openings and window openings of the bolt - connected sandwich thermal insulation wall panel 1. Among them, the coupling beam at the bottom of the window opening is replaced by an autoclaved lightweight concrete beam, and the autoclaved lightweight concrete beam is fixedly connected with the two - side bolt - connected sandwich thermal insulation wall panels 1 through clamping parts. Both ends of the energy - dissipating coupling beam 2 are integrally structured with the adjacent bolt - connected sandwich thermal insulation wall panels 1 through bolt connection. The energy - dissipating coupling beam 2 includes an upper connecting rod 201 and a lower connecting rod 202. Connecting blocks 3 are hinged at both ends of the upper connecting rod 201 and the lower connecting rod 202, and the connecting blocks 3 are all in contact with the corresponding bolt - connected sandwich thermal insulation wall panels 1. A number of tie pieces 5 are provided at the top and side of the bolt - connected sandwich thermal insulation wall panel 1. A number of screw holes 6 are opened on the surface of the connecting blocks 3. The bolt - connected sandwich thermal insulation wall panel 1 includes an inner leaf panel 101. A thermal insulation layer 102 is provided on one side of the inner leaf panel 101, and an outer leaf panel 103 is provided on the side of the thermal insulation layer 102 away from the inner leaf panel 101. A number of through - holes 7 corresponding to the screw holes 6 are opened on the outer leaf panel 103, the inner leaf panel 101 and the thermal insulation panel 102. Through - nuts 8 are threadedly connected in the through - holes 7. The through - nuts 8 pass through the corresponding number of through - holes 7 from the screw holes 6 on one side of the connecting block 3 to the screw holes 6 on the other side, realizing the bolt connection between the upper connecting rod 201 and the lower connecting rod 202 and the wall panel. In addition, through the design of the connecting block 3, the design of connecting the two bolt - connected sandwich thermal insulation wall panels 1 and the energy - dissipating coupling beam 2 in an articulated manner enables the upper connecting rod 201 or the lower connecting rod 202 to rotate appropriately around the connecting block 3 when subjected to external forces, and can absorb and disperse energy through the rotation of the energy - dissipating coupling beam 2 under earthquake action, thus reducing the direct impact on the wall body.

[0032] And through the design of the through - bolt connection method, not only the installation process is simplified and the construction efficiency is improved. More importantly, the fastening effect of the through - nuts 8 makes the combination between the connecting block 3 and the bolt - connected sandwich thermal insulation wall panel 1 closer, endowing the upper connecting rod 201 and the lower connecting rod 202 with higher strength and stability, effectively enhancing the wind - pressure resistance and seismic resistance of the entire wall body. At the same time, the bolt connection also allows for the rapid disassembly and replacement of the energy - dissipating coupling beam 2 when necessary, enhancing the maintainability and flexibility of the structure.

[0033] Both the upper connecting rod 201 and the lower connecting rod 202 are I-beams, and several reinforcing ribs 9 are welded in the hollow parts of the upper connecting rod 201 and the lower connecting rod 202. The design of the reinforcing ribs 9 is only used to ensure the connection stability of the upper connecting rod 201 and the lower connecting rod 202, and the steel beam does not participate in energy dissipation. In some specific application scenarios, such as occasions where large loads are borne or higher stiffness is required, relying solely on the strength of the I-beam itself may not meet the requirements. At this time, the design of the reinforcing ribs 9 can improve the connection stiffness after the upper connecting rod 201 and the lower connecting rod 202 are connected into one body, enabling it to better resist external loads and deformations.

[0034] Several diagonal web members 4 serving as energy dissipation elements are provided between the upper connecting rod 201 and the lower connecting rod 202. The two ends of the diagonal web member 4 are respectively hinged to the bottom wall of the upper connecting rod 201 and the top wall of the lower connecting rod 202. The diagonal web members 4 are in a cross-shaped structure and have no contact with each other. The axes of adjacent diagonal web members 4 are skew lines in space. During the elastic stage of the structure under earthquake action, that is, before the structure reaches plastic deformation, in cooperation with the cross layout of the diagonal web members 4, a highly efficient energy dissipation mechanism is formed. When the upper connecting rod 201 or the lower connecting rod 202 is subjected to an external force and undergoes a small deformation, since the deformation of one diagonal web member 4 is transmitted to the upper connecting rod 201 or the lower connecting rod 202 through its hinge point, it may indirectly affect the stress state of the adjacent diagonal web member 4. Through its layout of skew lines in space, separate individual deformations are complementary and do not affect each other. The deformation mode of the diagonal web member 4 will exhibit non-synchronous and non-coplanar characteristics, that is, the design of skew lines limits the direct coupling of deformations, avoids local stress concentration, helps to extend the service life of the structure, reduces mutual contact, and thus reduces the cumulative damage caused by long-term load effects.

[0035] Among them, each diagonal web member 4 includes an upper joint 401, a lower joint 402, and a hollow sleeve 403. The upper joint 401 and the lower joint 402 are respectively hinged to the bottom wall of the upper connecting rod 201 and the top wall of the lower connecting rod 202. Both ends of the sleeve 403 are slidably connected to the upper joint 401 and the lower joint 402 respectively. An energy dissipation component for generating strain energy through deformation to consume the externally input energy is provided inside the sleeve 403. With this design, the sleeve 403 can freely expand and contract within a certain range, so as to adapt to the vertical displacement change between the upper connecting rod 201 and the lower connecting rod 202. In extreme situations such as earthquakes, the telescopic movement of the sleeve 403 can absorb and disperse part of the seismic energy, reduce the vibration amplitude of the structure, thereby protecting the main structure from serious damage, improving the energy dissipation capacity, and enhancing the stability of the entire structure.

[0036] Specifically, such as Figure 2As shown, the energy-consuming components all include an upper elastic section 404 and a lower elastic section 405. The bottom end of the upper elastic section 404 is welded with an upper plastic energy-consuming section 408, and the top end of the lower elastic section 405 is welded with a lower plastic energy-consuming section 409. The bottom end of the upper plastic energy-consuming section 408 and the top end of the lower plastic energy-consuming section 409 are both welded with a main elastic section 406. The two main elastic sections 406 are in contact with each other. The sleeve 403 is provided with a through positioning hole corresponding to the position where the two main elastic sections 406 are in contact. The designs of the bottom end of the upper plastic energy-consuming section 408 and the lower plastic energy-consuming section 409 enable the external load to be evenly transmitted to the main elastic section 406, and the energy is dissipated through the interaction between the upper elastic section 404 and the lower elastic section 405 and the main elastic section 406, which helps to avoid local stress concentration and improve the overall energy-consuming efficiency of the main elastic section 406.

[0037] In addition, elastic connecting sections 407 are provided inside both the upper joint 401 and the lower joint 402. One end of each connecting section 407 is welded to the inner wall of the corresponding upper joint 401 or the inner wall of the lower joint 402, and the other ends of the two connecting sections 407 are respectively welded to the upper elastic section 404 and the lower elastic section 405. When an external load acts on the structure, a relative displacement will occur between the upper connecting rod 201 and the lower connecting rod 202, thereby driving the sleeve 403 of the diagonal web member 4 to expand and contract. During this process, as one of the energy-consuming components, the connecting section 407 can absorb and dissipate the energy generated by the external load through its telescopic deformation, which helps to reduce the impact on the main structure and improve the seismic performance of the structure. In addition, the design advantage of the connecting section 407 is that the telescopic design of the connecting section 407 enables the force transmission cylinder to adapt to loads and deformations in different directions. Whether it is a horizontal load or a vertical load, the connecting section 407 can respond through its flexible telescopic mechanism, thus ensuring the overall safety and stability of the structure.

[0038] When the inner leaf panel 101, the thermal insulation layer 102, and the outer leaf panel 103 are cast, they are connected into an integral panel through a plurality of tie members 5. The design of the tie members 5 realizes the tight connection between the layers of the bolt-connected sandwich thermal insulation wall panel 1, improves the strength of each layer of the bolt-connected sandwich thermal insulation wall panel 1, and also enhances the load-bearing capacities such as shear resistance and bending resistance of the wall panel. A sealing coating is applied to the surface of the tie member 5 at the part passing through the thermal insulation layer 102 to ensure the integrity and thermal insulation performance of the thermal insulation layer 102, and avoid heat transfer of the thermal insulation layer 102 caused by the perforation of the tie member 5, thereby ensuring the thermal insulation effect of the wall panel.

[0039] Embodiment 2: As shown in the appendix Figure 6As shown, the difference from Example 1 is that the anchor 5 includes an inner core layer 501 and an outer cladding layer 502, the outer cladding layer 502 is wrapped and fixed on the outside of the inner core layer 501, the inner core layer 501 is inserted into the outer cladding layer 502, and the inner core layer 501 is all scored steel wire. The scored steel wire is a high-strength material, and its surface is specially treated to form scores, which not only increases the friction between the steel wire and the outer cladding layer 502, but also enables the steel wire to better disperse stress when subjected to force, avoiding fracture caused by stress concentration. This design significantly enhances the connection strength of the anchor 5, ensuring that the wallboard can remain stable when subjected to external forces.

[0040] The outer layer 502 is made of GFRP composite resin, which has excellent mechanical properties and corrosion resistance and can effectively resist the erosion of the external environment. It is tightly wrapped around the notched steel wire, not only providing additional protection for the inner core layer 501, but also firmly connecting the steel wire with each layer through its good bonding performance, further enhancing the stability of each layer of the wallboard.

[0041] Embodiment 3: As attached Figure 4 and Figure 5 As shown, the difference from Example 2 is that when the overall structure is subjected to external force, the connection between the inner blade 101, the insulation layer 102 and the outer blade 103 at the connection block 3 will be subjected to a greater dispersed force than other positions. For this reason, the plurality of anchors 5 at the connection block 3 are designed to be arranged adjacent to each other as a group of two anchors 5, and the arrangement of each group of anchors 5 includes vertical anchors 5 and inclined anchors 5. The vertical anchors 5 are arranged at 90° to the insulation layer 102, while the inclined anchors 5 are arranged at 90° to the insulation layer 102. The layers 102 are arranged at 45°, and the vertical anchors 5 and the inclined anchors 5 form a triangular arrangement. On the one hand, after the bolt-connected sandwich insulation wall panel 1 is cast and formed, the anchors 5 are arranged for special stress-bearing parts, which can increase the number of connection points and improve the redundancy of the connection, making the connection between the inner blade 101, the insulation layer 102 and the outer blade 103 more stable, able to withstand greater external forces, effectively disperse external forces, reduce stress concentration at the connection parts, and thus reduce the risk of cracking. On the other hand, the stability principle of the triangle is used to further enhance the stability of the connection, and the triangular arrangement can more effectively disperse external forces, reduce stress concentration at the connection parts, and further improve the durability of each layer of the wall panel.

[0042] Obviously, the above embodiments are merely examples given for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to exhaustively list all implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the present invention.
