Description

Technical Field

[0001] The utility model relates to the technical field of building bearing capacity compensation, in particular to a pre-designed assembled building bearing capacity compensation composite component system. Background Art

[0002] With the rapid development of national economic construction, there are more and more various building structures, highway tunnels, railway tunnels, underground pipe galleries, underground tunnels and rail transit facilities. During the long-term operation and use of these facilities, due to the aging of their own materials, the operating environment or the influence of factors such as changes in the external environment, their main structures will inevitably experience various deformations and aging, mainly manifested as cracks, falling blocks and convergence deformation. The continuous development of these phenomena will destroy the integrity of the main structure of the building, reduce the bearing capacity of the structure, and also bury hidden dangers to the safe operation of the operation. Therefore, it is urgent to deal with these problems quickly and reliably.

[0003] At present, the existing technology has the following problems when compensating and reinforcing the bearing capacity of building structures:

[0004] 1. When carrying out the bearing capacity compensation of buildings, the existing technology usually uses an integral support structure of a single type of material, resulting in a single performance. Nowadays, steel structures are widely used for compensation. Although they have good bending resistance, in order to meet the designed building bearing capacity compensation, the steel needs to be of sufficient thickness to achieve the bending resistance required for bearing capacity compensation, which wastes materials, makes the materials heavy, and has high costs. If the steel thickness is not enough, the rigidity will be poor, resulting in insufficient bearing capacity compensation. At the same time, the steel is not corrosion-resistant and has poor insulation performance. Therefore, using a single steel cannot meet the full design requirements, especially in some narrow construction sites, and 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, these places have small spaces and limited downtime. The original building structures have certain rigidity and flexibility, and have high requirements for the insulation, fire prevention, and corrosion resistance of the selected bearing capacity compensation materials. If steel plates are used to reinforce the bearing capacity of the compensation structure, the pipelines and other equipment and facilities that affect the construction on the original structure must be removed in advance, and then transported to the site with large-scale transportation equipment, and then the steel materials are lifted and installed with mechanical equipment. In addition, open flame cutting, welding, pouring, spraying of anti-corrosion coatings and other processes are required on site, resulting in cumbersome construction procedures, high costs, and uncontrollable quality. Since steel must be cut and welded at the construction site, the toxic and harmful gases caused cannot be discharged in time in the small space, causing harm and corrosion to the construction personnel and existing instruments and equipment on site. Therefore, there are problems of difficult construction, high costs and long construction period. At the same time, the material stress generated after the welding of metal materials cannot be eliminated on site, which will harm the structure of the original building and thus affect the overall quality. The high temperature generated during welding will also destroy the performance and strength of the metal materials, and will burn and destroy the anti-corrosion layer on the front and back metal materials; even if post-anti-corrosion is done on site, the quality cannot be guaranteed due to limited conditions, especially the side of the interface between the reinforcement material and the original building structure. After the anti-corrosion layer is burned by the high temperature during welding, it is impossible to carry out anti-corrosion treatment. At the same time, due to the limitations of the processing technology, the steel cannot guarantee that there is no gap between the adjacent surfaces of the original building, and the subsequent glue injection cannot guarantee full filling, and no overlapping force is formed with the inner wall of the original building structure. Therefore, many safety hazards are left, which seriously affect the service life.

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

[0007] Therefore, if the existing technology is to meet the demand for bearing capacity compensation, there are problems such as high material integrity requirements, large materials, large weight and volume, and large mechanical equipment must be used for transportation and construction, which leads to slow construction progress and high overall costs. In summary, it is difficult for the existing technology to achieve fast and simple assembly construction without dismantling the original lines in the building or affecting the normal operation of the equipment, and to provide accurate bearing capacity compensation efficiently, with high quality and reasonably.

DETAILED DESCRIPTION

[0056] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clearly understood, the spirit of the contents disclosed in the present invention will be clearly explained with the accompanying drawings and detailed descriptions below. After understanding the embodiments of the contents of the present invention, any technician in the relevant technical field can change and modify the contents of the present invention according to the techniques taught by the contents of the present invention without departing from the spirit and scope of the contents of the present invention.

[0057] In order to solve the above technical problems, the utility model provides a pre-designed assembled building bearing capacity compensation composite component system, which is used to carry out rapid bearing capacity compensation construction of buildings or rail transit facilities structures on demand and in quantity, and with reduced comprehensive costs, without affecting the normal operation of the original lines and equipment in the building, and is particularly suitable for limited small spaces and limited construction time. Figures 1A to 1F As shown, the bearing capacity compensation composite component system includes:

[0058] A plurality of bearing capacity compensating composite components 100 are sequentially arranged along the extension direction of the inner wall of the building, and are used to compensate for the structural bearing capacity of the building, wherein each of the bearing capacity compensating composite components 100 is composed of a plurality of sub-components 110, and the plurality of sub-components 110 are spliced, attached and fixed on the inner wall of the building to compensate for the original structural bearing capacity of the building.

[0059] A plurality of segments of the sub-components 110 are spliced, fitted and fixed on the inner wall surface of a building structure or the inner wall of a shield concrete segment of a rail transit facility to form a bearing capacity compensation composite component 100. A plurality of bearing capacity compensation composite components 100 are arranged in sequence along the inner wall of the building, thereby pre-designing an assembled building bearing capacity compensation composite component system based on the required compensation amount on the compensated building structure, which can effectively support the insufficient structural bearing capacity of the original building structure or the original rail transit facility shield segment and compensate it as needed and in quantity.

[0060] In a specific implementation, there may be a variety of implementation schemes for the arrangement of the sub-component 110. For example, each section of the sub-component 110 may be formed by a plurality of cavity components 111 fixed side by side, and the sub-component 110 may be a grouting metal cavity or a metal hollow cavity according to the design requirements. Furthermore, the sub-component 110 may be a concrete grouting metal cavity or a metal hollow cavity without grouting concrete slurry. Grouting in the metal hollow cavity can effectively improve the bearing capacity compensation capacity and increase the compressive performance and stability of the material. In some cases where the strength of the metal hollow cavity meets the design requirements without grouting concrete slurry, concrete may not be injected to reduce its weight, reduce costs, and improve efficiency, thereby meeting the bearing capacity compensation requirements of different buildings. The metal hollow cavity or grouting metal cavity also serves as the skeleton of the pre-designed prefabricated building bearing capacity compensation composite component system, and plays a role in the bending and tensile resistance of the bearing capacity compensation composite component system in this composite material.

[0061] Furthermore, since stainless steel has relatively good corrosion resistance, fire resistance, rigidity, chemical stability and ductility, the cavity component 111 can preferably be a stainless steel cavity component.

[0062] In specific implementation, FIG. 5A to FIG. 5B As shown, in order to further improve the overall strength of the pre-designed assembled bearing capacity compensating composite component system and improve the bearing capacity, the pre-designed building bearing capacity compensating composite component system may also include:

[0063] The fiber composite layer 160 is disposed on the outer side of each segment of the sub-component 110 to enhance the strength of the sub-component 110 of the load-bearing capacity compensation composite component 100 , resist bending and tension, and restrict its deformation.

[0064] Through fiber composite metal, the performance advantages and characteristics of composite materials formed by the superposition of two or more materials can be effectively and fully utilized.

[0065] In a specific implementation, the fiber composite layer 160 may include multiple layers of fibers.

[0066] The multi-layer fibers can better improve the deformation resistance of the sub-component 110 and strengthen the core restraint of the fibers on the sub-component 110 . Furthermore, two adjacent layers of fibers in the multi-layer fibers can be cross-arranged along the circumference of the sub-component 110 .

[0067] In a specific implementation, there may be a variety of implementation schemes for the limited winding method of the fiber composite layer 160. For example, the fiber winding direction of the fiber composite layer 160 may be axial winding and / or circumferential winding along the component 110 of the load-compensating composite component. When the fiber composite layer 160 is set, the fibers are respectively arranged longitudinally (i.e., along the axial direction of the component 110 of the load-compensating composite component 100) and circumferentially (i.e., along the circumferential direction of the component 110 of the load-compensating composite component 100) and wound crosswise using a composite process on the outside of each section of the component 110 of the load-compensating composite component 100. The longitudinal fibers are arranged to enhance the bending strength and stiffness of the load-compensating composite component 100, and the circumferential fibers are arranged to enhance the core restraint force of the load-compensating composite component 100, which can improve the strength and ductility of the load-compensating composite component 100. Specifically, as Figure 5A As shown, the first fiber layer 161 is wound along the circumferential direction, and the second fiber layer 162 can be arranged along the axial direction. Figure 5B As shown, when the fibers are all wound circumferentially, the third fiber layer 163 and the fourth fiber layer 164 can be wound alternately in opposite directions.

[0068] After the flame-retardant glue is introduced through a special process to achieve a high degree of entanglement and compounding of the two materials, the deformation of the inner layer cavity component 111 is further restrained, and the overall peeling resistance, deformation resistance and coordinated bearing capacity between the two can be greatly enhanced, which can greatly enhance the elastic modulus, shear resistance and compressive resistance of the bearing capacity compensation composite component 100. On the premise of meeting the design requirements, the self-weight and cost of the bearing capacity compensation composite component 100 can be greatly reduced.

[0069] In a specific implementation, there are multiple implementations for selecting the material of the fiber composite layer 160. For example, the fiber composite layer 160 may be composed of a flame retardant resin and fibers, wherein the fibers include at least one of basalt fibers, carbon fibers, aramid fibers, and glass fibers. Furthermore, the outermost layer of the fiber composite layer 160 may be basalt fibers. Specifically, the outer fiber material of the fiber composite layer 160 is preferably basalt fiber, because its tensile strength, elastic modulus, corrosion resistance, insulation, fire resistance and chemical stability are relatively good, and it is cost-effective. The inner fiber material of the fiber composite layer 160 can be selected from other fiber materials that meet the performance requirements according to design requirements. Carbon fiber material is preferred because its fire resistance, corrosion resistance, chemical stability, tensile strength and elastic modulus are better than basalt fiber. However, the insulation of carbon fiber cannot fully meet the requirements of specific scenarios that require insulation, and its 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 fiber. The outer layer uses basalt fiber as a tensile, fire-resistant, corrosion-resistant and insulating layer, which can meet the design requirements.

[0070] In a specific implementation, in order to effectively improve the fireproof performance of the fiber composite layer 160, the pre-designed assembled building bearing capacity compensation composite component system may further include: a fireproof coating layer, which is applied to the outside of 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.

[0071] In a specific implementation, there are multiple implementation schemes for setting the sub-components 110 of the pre-designed assembled building bearing capacity compensation composite component 100. For example, after the sub-components 110 of multiple sections of the pre-designed building bearing capacity compensation composite component 100 are spliced, fitted and fixed 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 As shown, the number of sections of the pre-designed assembled building bearing capacity compensation composite component system sub-component 110 can be 3, and the number of the cavities can also be 3.

[0072] In the specific implementation, in order to facilitate the injection of concrete slurry on site, discharge the gas in the cavity, ensure the density of concrete in the metal tube cavity, and effectively improve the bearing capacity of the bearing capacity compensation prefabricated composite component, such as Figures 1A to 1F , FIG. 10A to FIG. 10D , FIG. 11A to FIG. 11D , FIG. 12A to FIG. 12BAs shown, each of the hollow bodies may have at least one grouting hole 113, at least one grouting hole 114 and at least one exhaust observation hole 115. The grouting hole 113, the grouting hole 114 and the exhaust observation hole 115 are all provided with an opening and closing device 116, and the exhaust observation hole 115 is provided at the top of the hollow body. The opening and closing device 116 may be built into the hollow body of the hollow member 111, or may be externally placed in the hollow body or outside the hollow body. The grouting hole 113 and the grouting hole 114 are provided at both ends of the hollow body.

[0073] In specific implementation, FIG. 12A to FIG. 12B As shown, in order to facilitate the grouting of the C-shaped, U-shaped and arc-shaped bearing capacity compensation composite component 100 cavity body to fully exhaust the gas in the arc top cavity, each cavity body arc top highest point may have at least one exhaust observation hole 115, the exhaust observation hole 115 is provided with an opening and closing device 116, the exhaust observation hole 115 can be set at the top of the outer wall of the cavity body or the bottom ends on both sides, and can also be set in the middle of both sides of the cavity body, a metal pipe is set in the exhaust observation hole 115, one end of which extends to the inside of the cavity, and the other end extends to the outside of the cavity.

[0074] In a specific implementation, the filler poured into the cavity can be arranged in a variety of embodiments. For example, the filler poured into the cavity can include at least one of concrete, mortar and high molecular polymer. Further, the filler can be preferably concrete. Concrete is preferred because concrete has advantages such as compression resistance, corrosion resistance, insulation and fire resistance, and concrete has a high cost performance.

[0075] In specific implementation, the pre-designed assembled building capacity-compensating composite component system can inject concrete into the cavity according to design requirements if it is necessary to enhance the compressive and shearing capacity. The concrete can be pre-injected in 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 concrete injection method can effectively reduce the weight of the capacity-compensating composite component 100 during installation, facilitate quick installation, and increase the cross-sectional inertia moment performance and compressive and bending performance of the capacity-compensating composite component 100. The bearing capacity compensation performance of the capacity-compensating composite component 100 can be greatly enhanced. It is a high-bearing capacity compensation reinforcement structure that integrates the tensile strength, ductility, compressive strength, bending resistance, corrosion resistance, fire resistance, insulation, suitable elastic modulus and the ability to be quickly assembled on site.

[0076] In a specific implementation, there may be a variety of embodiments for setting the connection between the sub-components 110. For example, FIG. 6A to FIG. 6E As shown, the sub-components 110 can be spliced ​​together through an inner connecting sleeve 130 .

[0077] Furthermore, there are also many embodiments for the arrangement of the inner connecting sleeve 130. For example, FIG. 6A to FIG. 6E As shown, the inner connecting sleeve 130 may include a first small-mouth end 131 and a second small-mouth end 132, wherein:

[0078] The cross-sectional shape of the first small opening 131 and the second small opening 132 is the same as the cross-sectional shape of the sub-component 110, and the cross-sectional area of ​​the first small opening 131 and the second small opening 132 is smaller than the internal cross-sectional area of ​​the sub-component 110 so as to adjust the connection angle of two adjacent sub-components 110; the first small opening 131 and the second small opening 132 are respectively welded to the inner walls of the connecting ends of two adjacent sub-components 110.

[0079] The cross-sectional area 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 a certain gap is left between the sub-component 110, so that the connection angle of two adjacent sub-components 110 can be relatively adjusted to better adapt to the inner wall of the building.

[0080] Further, such as FIG. 6A to FIG. 6E As shown, the first small opening 131 and the second small opening 132 respectively penetrate into the interior of two adjacent sub-components 110 to splice and fix the two adjacent sub-components 110. The cross-sectional area of ​​the first small opening 131 increases from small to large from the end to the middle, so that the first small opening 131 can adjust the connection angle after penetrating into the interior of one of the sub-components 110, thereby adjusting the relative connection angle of the two adjacent sub-components 110.

[0081] In a specific implementation, the gap between the sub-component 110 and the building can be fixed by various solutions. For example, the gap between the sub-component 110 and the inner wall of the building can be fixed by glue and / or anchor bolts 140 .

[0082] In the specific implementation, in order to effectively improve the connection strength of the connection parts, such as FIG. 7A to FIG. 7D , FIG. 9A to FIG. 9BAs shown, the bearing capacity compensation composite component 100 may also include: a reinforcing connecting plate 120, which is arranged to cover the outside of the connecting ends of the two adjacent sub-components 110, and the two ends of the reinforcing connecting plate 120 are respectively fixedly connected to the connecting ends of the two adjacent sub-components 110.
