Description

Technical Field

[0001] The present invention relates to the technical field of building bearing capacity compensation, and particularly to a pre-designed assembled building bearing capacity compensation composite component system. Background Art

[0002] With the rapid development of the national economic construction, there are more and more various building structures, highway tunnels, railway tunnels, underground utility tunnels, underground galleries and rail transit facilities. During the long-term operation and use of these facilities, due to the influence of factors such as the aging of their own materials, operating environment or external environmental changes, various deformations and aging of the main structure of the buildings will inevitably occur, mainly manifested as cracks, chipping and convergence deformation, etc. The continuous development of these phenomena will damage the integrity of the main structure of the building, reduce the bearing capacity of the structure, and at the same time pose a hidden danger to the safe operation, so it is urgent to quickly and reliably solve these problems.

[0003] Currently, when the existing technology is used for compensating and strengthening the bearing capacity of building structures, the following problems exist:

[0004] 1. When the existing technology compensates the bearing capacity of buildings, it usually uses an integral support structure of a single type of material, resulting in single performance. Currently, steel structures are used more for compensation. Although their bending resistance performance is good, in order to meet the designed building bearing capacity compensation amount, the steel needs to have a sufficient thickness to achieve the bending resistance ability required for bearing capacity compensation, which not only wastes materials, but also causes heavy materials and high costs. If the steel thickness is not enough, it will result in poor stiffness and insufficient bearing capacity compensation amount. At the same time, steel is not corrosion-resistant and has poor insulation performance. Therefore, using a single steel cannot meet the complete design requirements, especially in some narrow construction sites, it is impossible to use and transport a single large steel structure for construction.

[0005] 2. In small-space building areas such as rail transit facilities, the space is narrow and the outage time is limited. These original building structures have certain rigidity and flexibility, and there are also high requirements for the insulation, fire prevention, and anti-corrosion of the selected bearing capacity compensation materials. When using steel plates to reinforce the bearing capacity of the compensation structure, pipelines and other equipment facilities that affect construction on the original structure need to be removed in advance, and then transported to the site by large transportation equipment. Then, mechanical equipment is used to lift and install the steel materials, and on-site open-flame cutting, welding, pouring, spraying anti-corrosion coatings and other processes are also required. This results in cumbersome construction procedures, high costs, uncontrollable quality. Since the steel materials must be cut and welded on-site, the toxic and harmful gases generated cannot be discharged in time in the small space, which poses hazards and corrosion to the construction personnel and the existing instruments and equipment on-site. Therefore, there are problems of difficult construction, high costs, and long construction periods. At the same time, the material stress generated after welding of metal materials cannot be eliminated on-site, which will pose hazards to the original building structure, thereby affecting the overall quality. The high temperature generated during welding will also damage the performance and strength of the metal materials and burn and damage the anti-corrosion layers on the front and back metal materials. Even if post-anti-corrosion is done on-site, due to conditions, the quality cannot be guaranteed. Especially for the side where the reinforcement and strengthening materials are in contact with the original building structure, after the anti-corrosion layer is burned and damaged by the high temperature during welding, anti-corrosion treatment cannot be carried out again. At the same time, due to processing technology limitations, it is impossible to ensure that there is no gap between the steel materials and the contact surface of the original building, and it is also impossible to ensure that the glue injection is sufficient later, and there is no overlapping force formed with the inner wall of the original building structure. Therefore, many potential safety hazards are left, seriously affecting the service life.

[0006] 3. When using concrete with steel bars to compensate for the bearing capacity of the building structure, the supporting compensation structure needs to be made with a larger cross-sectional area to meet the design bending resistance requirements. However, in some narrow spaces, construction cannot be achieved due to reasons such as clearance.

[0007] Therefore, if the existing technology is to meet the requirements of the bearing capacity compensation amount, there are problems such as high requirements for material integrity, more materials, large weight and volume. During transportation and construction, large mechanical equipment must be used, and the construction progress is slow, resulting in high overall costs. In summary, it is very difficult for the existing technology to carry out fast, simple and assembled construction without removing the original lines in the building or affecting the normal operation of the equipment, and to efficiently, high-quality and reasonably provide an accurate bearing capacity compensation amount. Summary of the Invention

[0008] To solve the above technical problems, the present invention provides a pre-designed assembled building bearing capacity compensation composite member system, which can achieve rapid, demand-based and low-cost construction of building structure bearing capacity compensation without affecting the normal operation of buildings or facilities such as rail transit, and without the need to demolish existing lines, equipment and other facilities. It is particularly suitable for use in narrow spaces and occasions with a very short construction period. The bearing capacity compensation composite member system includes:

[0009] At least one bearing capacity compensation composite member for compensating the bearing capacity of the building structure. Each of the bearing capacity compensation composite members is composed of multiple sections of sub-members, and the multiple sections of sub-members are spliced, fitted and fixed on the inner wall of the building to compensate for the original bearing capacity of the building structure. Each section of the sub-member is formed by arranging multiple cavity members side by side and fixing them.

[0010] In a specific implementation, the cavity member is a grouting metal cavity or a metal cavity.

[0011] In a specific implementation, the bearing capacity compensation composite member system further includes:

[0012] A fiber composite layer, which is covered on the outside of each section of the sub-member and is used to enhance the strength of the sub-member.

[0013] In a specific implementation, the fiber composite layer includes multiple layers of fibers. The laying directions of the fibers in each layer are along the extending direction of the sub-member and circumferentially wound and laid, and the laying directions of adjacent two layers of fibers are arranged crosswise.

[0014] In a specific implementation, the fiber composite layer is composed of resin and fibers, and the fibers include at least one of basalt fiber, carbon fiber, aramid fiber and glass fiber.

[0015] In a specific implementation, the outermost layer of the fiber composite layer is basalt fiber or aramid fiber.

[0016] In a specific implementation, the bearing capacity compensation composite member system further includes:

[0017] A fireproof coating layer, which is applied outside the fiber composite layer and is used to improve the fireproof performance of the fiber composite layer.

[0018] In a specific implementation, after multiple sections of the sub-members are spliced, fitted and fixed on the inner wall of the building, the cavity members corresponding to all the sub-members are interconnected to form a cavity body, and the number of the cavity bodies is equal to the number of the cavity members.

[0019] In a specific implementation, the number of sections of the sub-member is 3, and the number of the cavity bodies is 3.

[0020] In specific implementation, each of the cavity bodies has at least one grouting hole, at least one slurry outlet hole, and at least one exhaust observation hole. The grouting hole, the slurry outlet hole, and the exhaust observation hole are all provided with opening and closing devices, and the exhaust observation hole is arranged at the top of the cavity body.

[0021] In specific implementation, the filling material poured into the cavity body is concrete slurry and / or polymer.

[0022] In specific implementation, adjacent two segments of the sub-components are fixedly spliced through an internal connection sleeve.

[0023] In specific implementation, the internal connection sleeve includes a first small-end and a second small-end, where:

[0024] The first small-end and the second small-end respectively penetrate into the interiors of adjacent two sub-components to splice and fix the adjacent two sub-components;

[0025] The cross-sectional area of the first small-end gradually increases from the end to the middle, so that the first small-end can adjust the connection angle after penetrating into the interior of one sub-component, thereby adjusting the relative connection angle between the adjacent two sub-components.

[0026] In specific implementation, the gap between the bearing capacity compensation composite component and the inner wall of the building is fixedly connected through glue and / or anchor bolts.

[0027] In specific implementation, this bearing capacity compensation composite component system further includes:

[0028] A strengthening connecting plate, which is covered and arranged outside the connection ends of adjacent two sub-components, and both ends of the strengthening connecting plate are fixedly connected to the connection ends of adjacent two sub-components respectively.

[0029] In specific implementation, both ends of the strengthening connecting plate are fixedly connected to the connection ends of adjacent two sub-components respectively through anchor bolts and / or glue.

[0030] In specific implementation, this bearing capacity compensation composite component system further includes:

[0031] At least one anchor bolt fixing reserved pipe and anchor bolts. The anchor bolt fixing reserved pipe is arranged on the bearing capacity compensation composite component and is used for the anchor bolts to pass through to fix the bearing capacity compensation composite component on the inner wall of the building. Among them, the anchor bolt fixing reserved pipe penetrates through the bearing capacity compensation composite component, and both ends have flanging parts extending to the outside of the bearing capacity compensation composite component.

[0032] In specific implementation, the anchor bolt is one or any combination of expansion anchor bolts, chemical rebar anchor bolts, and pre-expanded chemical anchor bolts.

[0033] In specific implementation, the bearing capacity compensation composite member is in a C shape, U shape, S shape, rectangular shape, trapezoidal shape or linear shape, and the cross section of the cavity member is square, rectangular, polygonal or trapezoidal.

[0034] In specific implementation, the bearing capacity compensation composite member system further includes:

[0035] A support frame, which is arranged at both ends of the bearing capacity compensation composite member and is used to eliminate the gap between both ends of the bearing capacity compensation composite member and the support points of the original building.

[0036] In specific implementation, the bearing capacity compensation composite member system further includes:

[0037] A gap filling structure, which is arranged at the gap between the bearing capacity compensation composite member and the inner wall of the building and is used to improve the fitting degree between the bearing capacity compensation composite member and the inner wall of the building.

[0038] The pre-designed bearing capacity compensation composite member system for prefabricated buildings provided by the present invention is such that before production in the factory, the structural shape of the original building is surveyed first, and the design institute calculates the data volume of the additional compensation bearing capacity required for the structure of the original building. The factory pre-selects and tests the corresponding data of each material intended to be combined, and based on the measured data, conducts material matching to meet the requirements of the designed bearing capacity compensation amount and shape. It is prefabricated and compound-produced into a profiling sub-component that can be quickly assembled, and then a construction plan that can be quickly assembled on site is formulated. The sub-components are transported to the construction site in parts for quick assembly. This pre-designed bearing capacity compensation composite member system for prefabricated buildings can not only meet various design requirements and achieve the purpose of quick installation, but also avoid excessive use of materials. Because before production, the shape of the original building structure and the on-site assembly method are surveyed and designed, and an installation plan that can avoid these obstacles is pre-formulated according to the situation at the construction site and the pipeline and equipment conditions. Therefore, during on-site installation, there is no need to demolish the existing pipelines and various equipment, nor is there a need for welding and the use of large equipment for construction. The construction is both safe and can effectively save costs, greatly improving the construction efficiency and ensuring that the construction quality is consistent with the design standards, and extending the service life of the building.

Specific embodiments

[0057] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer and more understandable, the spirit of the content disclosed by the present invention will be clearly described below with reference to the attached drawings and detailed description. After any person skilled in the relevant technical field understands the embodiments of the content of the present invention, they can make changes and modifications based on the techniques taught by the content of the present invention, which do not depart from the spirit and scope of the content of the present invention.

[0058] To solve the above technical problems, the present invention provides a pre-designed assembled building bearing capacity compensation composite member system, which can quickly compensate the bearing capacity of the building or rail transit facility structure as needed and in accordance with quantity, and can reduce the comprehensive cost, without affecting the normal operation of the original lines and equipment in the building, especially suitable for limited small spaces and limited construction time, such as Figures 1A to 1F As shown, the bearing capacity compensation composite member system includes:

[0059] At least one bearing capacity compensation composite member 100, which is used to compensate the bearing capacity of a building structure. Each of the bearing capacity compensation composite members 100 is composed of multiple sub-members 110. The multiple sub-members 110 are spliced, fitted and fixed on the inner wall of the building to compensate the bearing capacity of the original building structure. Each sub-member 110 is formed by arranging multiple cavity members 111 side by side and fixing them.

[0060] The multiple sub-members 110 are spliced, fitted and fixed on the inner wall surface of the building structure or the inner wall of the shield concrete segment of the rail transit facility to form a bearing capacity compensation composite member 100. Multiple bearing capacity compensation composite members 100 are arranged in sequence along the inner wall of the building, so as to form a pre-designed assembled building bearing capacity compensation composite member system on the compensated building structure according to the required compensation amount, which can effectively support the insufficient bearing capacity existing in the original building structure or the original rail transit facility shield segment and compensate according to the demand and quantity.

[0061] In specific implementation, there can be various implementation schemes for the setting of the sub-member 110. For example, the sub-member 110 can be a grouted metal cavity or a metal cavity according to the design requirements. Further, the sub-member 110 can be a concrete grouted metal cavity or a metal cavity without grouted concrete. Grouting in the metal cavity can effectively improve the bearing capacity compensation ability and increase the compressive performance and stability of the material. When the strength of some metal cavities can meet the design requirements without grouting concrete, concrete can not be grouted to reduce its weight, lower the cost and improve the efficiency, so as to meet the bearing capacity compensation amount requirements of different buildings. The metal cavity or the grouted metal cavity also serves as the skeleton of the pre-designed assembled building bearing capacity compensation composite member system, and plays a role in bending resistance and tensile resistance of the bearing capacity compensation composite member system in this composite material.

[0062] Further, due to the relatively good corrosion resistance, fire resistance, flexibility, chemical stability and ductility of the stainless steel material, the cavity member 111 can preferably be a stainless steel cavity member.

[0063] In specific implementation, as Figures 5A to 5B shown, in order to further improve the overall strength of the pre-designed assembled bearing capacity compensation composite member system and improve the bearing capacity, the pre-designed building bearing capacity compensation composite member system can also include:

[0064] A fiber composite layer 160, which is covered on the outside of each sub-member 110 and is used to enhance the strength of the sub-member 110 of the bearing capacity compensation composite member 100, resist bending and tension and restrain its deformation.

[0065] Through the fiber composite metal, it can effectively give full play to the performance advantages and characteristics of the composite material after the superposition of two or more materials.

[0066] In specific implementation, the fiber composite layer 160 may include multiple layers of fibers.

[0067] The multiple layers of fibers can better improve the anti-deformation ability of the sub-component 110, strengthen the core binding force of the fibers on the sub-component 110. Further, two adjacent layers of fibers in the multiple layers of fibers can be arranged to cross each other along the circumferential direction of the sub-component 110.

[0068] In specific implementation, there can be various implementation schemes for the limiting winding mode of the fiber composite layer 160. For example, the winding direction of the fibers in the fiber composite layer 160 can be winding along the axial direction of the bearing capacity compensation composite member 100 and / or the circumferential direction. When setting the fiber composite layer 160, the fibers are respectively arranged longitudinally (i.e., along the axial direction of the sub-component 110 of the bearing capacity compensation composite member 100) and circumferentially (i.e., along the circumferential direction of the sub-component 110 of the bearing capacity compensation composite member 100) and wound and crossed by a composite process on the outer side of each section of the sub-component 110 of the bearing capacity compensation composite member 100. The longitudinal fiber arrangement is used to enhance the bending strength and stiffness of the bearing capacity compensation composite member 100, and the circumferential fiber arrangement is used to enhance the core binding force of the bearing capacity compensation composite member 100, which can improve the strength and ductility of the bearing capacity compensation composite member 100. Specifically, as Figure 5A shown, the first fiber layer 161 is wound circumferentially, and the second fiber layer 162 can be arranged axially. Further, as Figure 5B shown, when the fibers are all wound circumferentially, the third fiber layer 163 and the fourth fiber layer 164 can be wound in a staggered manner in opposite directions.

[0069] After introducing a flame-retardant glue through a special process to achieve high winding and compounding of the two materials, it further plays a role in restricting the deformation of the inner cavity member 111, and can greatly enhance the overall anti-peeling property, anti-deformation ability and coordinated bearing capacity between the two, and can greatly enhance the elastic modulus, shear resistance and compressive performance of the bearing capacity compensation composite member 100. On the premise of meeting the design requirements, it can greatly reduce the self-weight and cost of the bearing capacity compensation composite member 100.

[0070] In specific implementation, there can be multiple implementation schemes for the selection of the material of the fiber composite layer 160. For example, the fiber composite layer 160 can be composed of a flame-retardant resin and fibers, and the fibers include at least one of basalt fibers, carbon fibers, aramid fibers, and glass fiber layers. Further, the outermost layer of the fiber composite layer 160 can be basalt fibers. Specifically, the outer layer fiber material of the fiber composite layer 160 is preferably basalt fibers because of their relatively good tensile strength, elastic modulus, corrosion resistance, insulation, fire resistance, and chemical stability, and high cost performance. The inner layer fiber material of the fiber composite layer 160 can be selected according to design needs from other fiber materials that meet the performance requirements. Carbon fiber material is preferably used because its fire resistance, corrosion resistance, chemical stability, tensile property, and elastic modulus are better than those of basalt fibers. However, the insulation of carbon fibers cannot fully meet the requirements of specific scenarios that require insulation, and the relative price is relatively high. Therefore, it can be used as the inner layer of the fiber composite layer 160 to supplement the performance of basalt fibers. Using basalt fibers as the tensile, fire-resistant, corrosion-resistant, and insulating layer on the outer layer can already meet the design requirements.

[0071] In specific implementation, in order to effectively improve the fire resistance of the fiber composite layer 160, the pre-designed assembled building bearing capacity compensation composite component system can further include: a fireproof coating layer applied outside the fiber composite layer 160. The fireproof coating layer can further improve the overall fireproof rating of the pre-designed assembled building bearing capacity compensation composite component system.

[0072] In specific implementation, there can be multiple implementation schemes for the setting of the sub-component 110 of the pre-designed assembled building bearing capacity compensation composite component 100. For example, after splicing and fitting and fixing multiple sections of the sub-component 110 of the pre-designed building bearing capacity compensation composite component 100 on the inner wall of the building and the inner wall of the shield segment of the rail transit facility, the cavity components 111 corresponding to all the sub-components 110 can be interconnected to form a cavity body, and the number of cavities in the cavity body can be equal to the number of the cavity components 111. Further, as Figures 1A to 1F shown, the number of sections of the sub-component 110 of the pre-designed assembled building bearing capacity compensation composite component system can be 3, and the number of cavity bodies can also be 3.

[0073] In specific implementation, in order to facilitate the injection of concrete slurry on site, discharge the gas in the cavity, and ensure the density of the concrete in the metal pipe cavity, thereby effectively improving the bearing capacity of the bearing capacity compensation assembled composite component, as Figures 1A to 1F 、 Figures 10A to 10D 、 Figures 11A to 11D 、 Figures 12A to 12BAs shown, each of the cavity bodies may have at least one grouting hole 113, at least one slurry outlet hole 114, and at least one exhaust observation hole 115. The grouting hole 113, the slurry outlet hole 114, and the exhaust observation hole 115 are all provided with opening and closing devices 116. The exhaust observation hole 115 is arranged at the top of the cavity body. The opening and closing device 116 may be built into the cavity of the cavity member 111, or may be externally placed inside or outside the cavity body. The grouting hole 113 and the slurry outlet hole 114 are arranged at both ends of the cavity body.

[0074] In specific implementation, as Figures 12A to 12B shown, in order to facilitate the full discharge of gas in the arc-top cavity during the grouting of the cavity of the C-shaped, U-shaped, and arc-shaped bearing capacity compensation composite member 100, each cavity body may have at least one exhaust observation hole 115 at the highest point of the arc top. The exhaust observation hole 115 is provided with an opening and closing device 116. The exhaust observation hole 115 can be arranged at the top or the bottom ends of both sides of the outer wall of the cavity body, or can be arranged in the middle of both sides of the cavity body. A metal pipe is arranged in the exhaust observation hole 115, with one end extending into the cavity and the other end extending outside the cavity.

[0075] In specific implementation, there can be various implementation schemes for the filling material poured into the cavity body. For example, the filling material poured into the cavity body may include at least one of concrete, mortar, and polymer. Further, the filling material can preferably be concrete. Concrete is preferred because it has advantages such as compressive resistance, anti-corrosion, insulation, and fire resistance, and it has a high cost performance.

[0076] In specific implementation, according to the design requirements, if it is necessary to enhance the compressive and shear resistance of the pre-designed assembled building bearing capacity compensation composite member system, concrete can be injected into the cavity body. The concrete can be pre-injected at the factory. In order to adapt to some sites where construction and transportation are inconvenient, it can also be quickly injected on-site through the grouting hole 113. The on-site injection of concrete can effectively reduce the weight of the bearing capacity compensation composite member 100 during installation, facilitate quick installation, and can also increase the section moment of inertia performance, compressive and flexural performance of the bearing capacity compensation composite member 100 by a large value, and can greatly enhance the bearing capacity compensation performance of the bearing capacity compensation composite member 100. It is a high-bearing capacity compensation type reinforcement structure that integrates the tensile, anti-ductility, compressive, flexural performance, anti-corrosion, fire protection, insulation, appropriate elastic modulus of the fiber-reinforced composite metal and concrete, and can be quickly assembled in parts on-site.

[0077] In specific implementation, there can be various implementation schemes for the connection between the sub-components 110. For example, as Figures 6A to 6E shown, the sub-components 110 can be spliced together through an internal connection sleeve 130.

[0078] Furthermore, there can be various implementation schemes for the setting of the inner connecting sleeve 130. For example, as Figures 6A to 6E shown, the inner connecting sleeve 130 may include a first small end 131 and a second small end 132, where:

[0079] The cross-sectional shapes of the first small end 131 and the second small end 132 are the same as the cross-sectional shape of the sub-component 110, and the cross-sectional areas of the first small end 131 and the second small end 132 are smaller than the internal cross-sectional area of the sub-component 110 to adjust the connection angle between two adjacent sub-components 110; the first small end 131 and the second small end 132 are respectively welded to the inner walls of the connection ends of two adjacent sub-components 110.

[0080] The cross-sectional areas of the first small end 131 and the second small end 132 can be smaller than the internal cross-sectional area of the sub-component 110 and there is a certain gap between them and the sub-component 110, so that two adjacent sub-components 110 can relatively adjust the connection angle, which is more adaptable to the inner wall of the building.

[0081] Furthermore, as Figures 6A to 6E shown, the first small end 131 and the second small end 132 respectively penetrate into the interiors of two adjacent sub-components 110 to splice and fix two adjacent sub-components 110. The cross-sectional area of the first small end 131 gradually increases from the end to the middle, so that the first small end 131 can adjust the connection angle after penetrating into the interior of one sub-component 110, and further adjust the relative connection angle between two adjacent sub-components 110.

[0082] In specific implementation, the gap between the sub-component 110 and the building can be fixed by various schemes. For example, the gap between the sub-component 110 and the inner wall of the building can be connected and fixed by glue and / or anchor bolts 140.

[0083] In specific implementation, in order to effectively improve the connection strength of the connection part, as Figures 7A to 7D 、 Figures 9A to 9BAs shown, the bearing capacity compensation composite member 100 may further include: a reinforcing connecting plate 120, which is covered and arranged outside the connecting ends of two adjacent sub-members 110, and both ends of the reinforcing connecting plate 120 are fixedly connected to the connecting ends of two adjacent sub-members 110 respectively. The purpose of setting the reinforcing connecting plate 120 is to enhance the strength of the connecting part and ensure the overall performance of the bearing capacity compensation composite member 100 after the sub-members 110 are connected. Further, in order to effectively ensure the connection stability, both ends of the reinforcing connecting plate 120 may be fixedly connected to the connecting ends of two adjacent sub-members 110 respectively through anchor bolts 140 and / or glue layers 123. The anchor bolts 140 may pass through the reinforcing connecting part and the sub-member 110 in sequence through reserved anchor bolt holes 122 and anchor bolt fixing reserved pipes 170, and be fixed to the building. When the reinforcing connecting plate 120 is arranged, a plurality of reinforcing stamping ribs 121 may be arranged along the extension direction of the body, so as to enhance the overall strength.

[0084] In specific implementation, in order to effectively improve the connection stability between the pre-designed prefabricated building bearing capacity compensation composite member system and the building, such as Figures 3A to 3C , Figures 4A to 4E , Figures 9A to 9B shown, the pre-designed prefabricated building bearing capacity compensation composite member system may further include:

[0085] At least one anchor bolt fixing reserved pipe 170 and anchor bolts 140, the anchor bolt fixing reserved pipe is arranged on the bearing capacity compensation composite member 100 for the anchor bolts 140 to pass through to fix the bearing capacity compensation composite member 100 on the inner wall of the building. Among them, the anchor bolt fixing reserved pipe 170 penetrates through the bearing capacity compensation composite member 100, and both ends have flanging parts 171 extending to the outside of the bearing capacity compensation composite member 100. Among them, the setting of the flanging part 171 is to restrain the loose fracture fibers caused by the reserved holes in the fiber composite layer 160 and play a role in pressing the fracture fibers. Further, the anchor bolts 140 may be one or any combination of expansion anchor bolts, chemical anchor bolts for implanting bars, and pre-expanded chemical anchor bolts.

[0086] Further, there may be various implementation schemes for the structure of the anchor bolts 140 when they are arranged. For example, as Figures 8A to 8CAs shown, the anchor bolt 140 may include an anchor bolt body 141, a locking nut 143, a large washer 144, a threaded glue guide groove 145, a linear glue guide groove 147, a pre-expansion friction plate 146, and a bolt head 142. Among them, the locking nut 143 and the large washer 144 are sequentially arranged at the root of the anchor bolt body 141. The threaded glue guide groove 145 is circumferentially arranged in a threaded shape on the anchor bolt body 141. The linear glue guide groove 147 is arranged radially outside the anchor bolt body 141. The pre-expansion friction plate 145 and the bolt head 142 are arranged at the top of the anchor bolt body 141. The bolt head 142 is arranged in a conical shape and has two conical surfaces, a positive conical surface and an inverted conical surface.

[0087] When installing the pre-designed assembled building bearing capacity compensation composite component system at the construction site of a building, glue with good weather resistance and flame retardancy and pre-micro-expansion rapid chemical anchor bolts are used to connect to the surface of the original building structure or the inner wall of the shield segment of rail transit facilities. Among them, the surface of the original building structure and the surface of the pre-designed assembled building bearing capacity compensation composite component system are connected by glue. The bonding area is large, and the shear resistance and peel resistance are good, which is the main connection and force transmission part of the two. The pre-micro-expansion rapid chemical anchor bolt is used as the reserve connection and force-bearing part of the two. The glue and the anchor bolt 140 are combined and connected to achieve a double-insurance connection effect.

[0088] In specific implementation, there can be multiple implementation schemes for setting the cross-sectional shape of the cavity member 111. For example, the cross-sectional shape of the cavity member 111 may include at least one of a square, a rectangle, a polygon, and a trapezoid.

[0089] In specific implementation, in order to further improve the strength of the bearing capacity compensation of the structure, as Figures 15A to 15E shown, the bearing capacity compensation composite component system may also be provided with a support frame 150 when necessary:

[0090] The support frame 150 is arranged at both ends of the bearing capacity compensation composite component 100 and is used to eliminate the gap between both ends of the bearing capacity compensation composite component 100 and the support points of the original building. The setting of the support frame 150 is to better eliminate the gap between the bearing capacity compensation composite component 100 and the support points of the original building, thereby enhancing the reliability of the connection between the support points and the end of the bearing capacity compensation composite component 100 and the strength of the bearing capacity compensation. Further, the support frame 150 may include a body 151 and an adjustment bolt 152. The adjustment bolt 152 can effectively adjust the overall height of the support frame 150, thereby improving adaptability.

[0091] In specific implementation, as Figure 13AAs shown in the figure, in order to effectively improve the fitting degree between the bearing capacity compensation composite member 100 and the building, the bearing capacity compensation composite member system may further include: a gap filling structure 180, which is arranged at the gap between the bearing capacity compensation composite member 100 and the inner wall of the building, and is used to improve the fitting degree between the bearing capacity compensation composite member 100 and the inner wall of the building.

[0092] There are various implementation schemes for the setting of the gap filling structure 180. For example, as Figure 13A , Figure 13B shown, the gap filling structure 180 may be a fiber filling structure 180a: including three layers, that is, a unidirectional fiber layer 182 is arranged between two grid fiber layers 181, so as to improve the overall strength of the structure. For another example, as Figure 14A , Figure 14B shown, the gap filling structure 180 may be a steel plate filling structure 180b, which is composed of multiple steel plates 183, and fiber layers 184 are arranged between each layer of steel plates.

[0093] In summary, for the pre-designed prefabricated building bearing capacity compensation composite member system provided by the present invention, the bearing capacity compensation index of the building can be pre-designed in the factory according to requirements, the required materials can be pre-selected and the bearing capacity data of various materials can be tested, and then the materials can be designed, matched and combined according to the obtained various test data to meet the design requirements. Then, various materials that meet the data requirements are prefabricated and the installation scheme is designed, and then they are transported to the construction site in parts for assembly.

And during the production process, according to how to avoid the existing pipelines and equipment conditions at the construction site, the shape of the sub-components 110 of the pre-designed prefabricated building bearing capacity compensation composite member system and the on-site assembly scheme are pre-designed, so that there is no need to demolish the existing pipelines and various equipment during on-site installation, and there is no need for welding and the use of large equipment for construction. The construction is both safe and can effectively save costs, greatly improving the construction efficiency and ensuring that the construction quality is consistent with the design standards, and prolonging the service life of the building.
