Description

Technical Field

[0001] This application relates to the field of building technology, and in particular to seismic-strengthening structures for building construction. Background Technology

[0002] With the development of the modern construction industry, the seismic performance design level of buildings has been continuously improved. Some older buildings can no longer meet current usage requirements and pose significant safety hazards. In order to ensure the safety and functionality of buildings, reinforcement and renovation are necessary. Currently, common seismic reinforcement methods for buildings include carbon fiber reinforcement, steel plate bonding reinforcement, and steel strand mesh reinforcement.

[0003] The related technology discloses a high-strength polymer mortar steel strand mesh reinforcement structure, including a steel strand mesh disposed in the reinforced area. A polymer mortar layer is disposed on the surface of the steel strand mesh, and the polymer mortar layer bonds the steel strand mesh to the reinforced component in the reinforced area to form a whole. The steel strand mesh is fixed to the reinforced area by anchor nails.

[0004] Steel strand mesh is tensioned and fixed to the reinforced area of ​​a building using anchor bolts. During the installation process, the anchor bolts may deviate from their intended anchoring positions due to positioning errors or drilling errors, causing the steel strands to deform under tension after fixing. This affects the tensile strength of the steel strands and thus the reinforcement effect on the building. Summary of the Invention

[0005] In order to reduce the tension deformation of steel strand mesh caused by anchor nail position deviation during the reinforcement construction of building steel strand mesh, this application provides a seismic reinforcement structure for building construction.

[0006] The seismic strengthening structure for building construction provided in this application adopts the following technical solution:

[0007] A seismic reinforcement structure for building construction includes a steel strand mesh, anchoring components, and a polymer mortar layer. The anchoring components are used to fix the steel strand mesh to the reinforced area of ​​the building. Both the anchoring components and the steel strand mesh are embedded in the polymer mortar layer. Multiple anchoring components are provided, with two anchoring components located on opposite sides of the steel strand mesh. Each anchoring component includes multiple anchor nails arranged at intervals along a straight line. A circular plate is rotatably fitted around each anchor nail, and the circular plate is eccentrically positioned relative to the anchor nail. A connecting rod is connected to the multiple circular plates, and a connecting groove is provided along the length of the connecting rod. The circular plates and the connecting groove are slidably connected along the length of the connecting groove. The connecting rod is provided with multiple tensioning brackets, which are equidistantly arranged along the length of the connecting rod. The connecting rod connects the steel strands of the steel strand mesh through the tensioning brackets.

[0008] By adopting the above technical solution, during the construction of seismic-strengthened structures, anchor holes for installing anchor nails are first drilled at predetermined locations in the reinforced area of ​​the building. Then, the anchor nails of the anchoring assembly are anchored into the reinforced area. When there is a deviation in the relative position between the anchor holes, the circular plate of the anchoring assembly can rotate around the anchor nail and slide relative to the connecting rod to adapt to the installation position of the anchor nail. After the anchoring assembly is installed, the steel strand mesh is connected and fixed to each anchoring assembly. The anchoring assembly connects the steel strands of the steel strand mesh through tensioning connectors. The spacing of the tensioning connectors is not affected by the positional deviation of the anchor holes, which helps to ensure a more uniform tension of the steel strand mesh and makes the reinforcement effect of the steel strand mesh less susceptible to being affected.

[0009] Optionally, the connecting rod includes two parallel round rods connected by multiple connecting blocks; the gap between the two round rods serves as the connecting groove; the outer circumferential surface of the circular plate is provided with an annular groove; the groove wall of the annular groove is configured as an arc surface adapted to the round rods; and the circular plate is snapped between the two round rods through the annular groove.

[0010] By adopting the above technical solution, the circular plate is snapped between the two circular rods through an annular groove. The groove wall of the annular groove is adapted to the circular rod, so that the contact between the circular plate and the two circular rods is sufficient, which helps to ensure the stability of the connection between the circular plate and the two circular rods.

[0011] Optionally, the two connecting blocks located at both ends of the connecting rod are defined as end connecting blocks. The end connecting blocks are threaded with tightening screws, which are parallel to the round rod and are used to abut against the outer circumferential surface of the round plate.

[0012] By adopting the above technical solution, after the anchoring components are installed in the reinforced area of ​​the building and the positions of each circular plate are adjusted, the circular plates located at both ends of the connecting rod are tightened using the tightening screws. This keeps the position of the connecting rod relative to the position of the anchoring nail, thereby fixing the position of the anchoring component relative to the building. Furthermore, the two tightening screws can also be used to fine-tune the position of the connecting rod along its length, thereby aligning the connecting rods of the two opposing anchoring components along their length. This helps to ensure that the tension direction of the anchoring components on the steel strand mesh is perpendicular to the length direction of the connecting rods of the anchoring components, further reducing the possibility of deformation of the steel strand mesh.

[0013] Optionally, the connecting rod is provided with a plurality of wire rings, which are alternately arranged with the circular plate along the length of the connecting rod. The wire rings have a twisted connection part and are used to force the two circular rods to move closer to each other to clamp the circular plate.

[0014] By adopting the above technical solution, the wire ring is formed by twisting the two ends of the wire together. The twisted connection part of the wire ring can be twisted, so that the wire ring can force the two round rods to come closer to each other, thereby clamping the round plate between the two round rods and making the connection between the connecting rod and the round plate more stable.

[0015] Optionally, the tensioning connector includes a connecting hook and an internal threaded sleeve. One end of the internal threaded sleeve is rotatably connected to the connecting rod, and the rotation center line between the internal threaded sleeve and the connecting rod coincides with the center line of the internal threaded sleeve. The tensioning connector connects to the steel strand mesh through the connecting hook. One end of the connecting hook is provided with a threaded rod, and the threaded rod is threadedly connected to the internal threaded sleeve.

[0016] By adopting the above technical solution, after the steel strand mesh is connected to each anchoring component, the tensioning hook can be tightened by rotating the internal threaded sleeve, thus making the steel strand mesh taut.

[0017] Optionally, the internal threaded sleeve has multiple through holes, the center lines of the through holes are coplanar with the center line of the internal threaded sleeve, and the through holes simultaneously penetrate both opposite sides of the internal threaded sleeve; the multiple through holes are distributed at intervals along the circumference of the internal threaded sleeve.

[0018] By adopting the above technical solution, when rotating the internally threaded sleeve, a rod-shaped tool is passed through the through hole of the internally threaded sleeve to apply torque, causing the internally threaded sleeve to rotate. When the rod-shaped tool is obstructed by the building surface, it can be pulled out and inserted into other through holes to facilitate continuous rotation of the internally threaded sleeve. The through hole simultaneously penetrates both opposite sides of the internally threaded sleeve, allowing the rod-shaped tool to pass through both opposite sides at the same time. When the rod-shaped tool applies torque to the internally threaded sleeve, it is less likely to cause damage. Furthermore, during the construction of the polymer mortar layer, the polymer mortar can enter the inner side of the internally threaded sleeve through the through hole, filling the fit gap between the internally threaded sleeve and the threaded rod, and even filling the inner cavity of the internally threaded sleeve, which helps to improve the stability of the connection between the internally threaded sleeve and the threaded rod.

[0019] Optionally, the plurality of through holes are spaced apart along the length direction of the internal threaded sleeve.

[0020] By adopting the above technical solution, the through holes are spaced apart along the length of the internal threaded sleeve, which increases the distance between two adjacent through holes, thereby helping to reduce the weakening effect of the through holes on the structural strength of the internal threaded sleeve.

[0021] Optionally, a limiting steel wire is provided through a plurality of the internal threaded sleeves of the anchoring assembly, and the limiting steel wire passes through a through hole of each of the internal threaded sleeves in sequence.

[0022] By adopting the above technical solution, after the steel strand mesh is installed and tensioned by adjusting the internal threaded sleeves, the limiting wires are sequentially passed through one through hole of each internal threaded sleeve. Under the obstruction of the limiting wires, the internal threaded sleeves are difficult to rotate around their own axis, thus limiting the internal threaded sleeves and enabling the tensioning connector to maintain the tension of the steel strand mesh.

[0023] Optionally, the end of the connecting hook away from the threaded rod is used to abut against the reinforced area of ​​the building.

[0024] By adopting the above technical solution, when the connecting hook tightens the steel strand mesh, the connecting hook is subjected to the reaction force of the steel strand mesh, causing the connecting hook to deform with an increased hook opening. By having the end of the connecting hook away from the threaded rod abut against the reinforced area of ​​the building, the deformation force of the connecting hook acts on the surface of the building, thus limiting the deformation of the connecting hook and helping to maintain the tension of the steel strand mesh.

[0025] Optionally, the end of the connecting hook away from the threaded rod extends into a straight rod portion, which is parallel to the threaded rod and is used to abut against the reinforced area of ​​the building.

[0026] By adopting the above technical solution, the connecting hook abuts against the reinforced area of ​​the building through the straight rod, making it more difficult for the connecting hook to undergo large deformation of the hook opening.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. During the construction of seismic-resistant reinforced structures, anchor holes for installing anchor nails are first drilled in the reinforced area of ​​the building according to the predetermined position. Then, the anchor nails of the anchoring assembly are anchored in the reinforced area of ​​the building. When there is a deviation in the relative position between the anchor holes, the circular plate of the anchoring assembly can rotate around the anchor nail and slide relative to the connecting rod to adapt to the installation position of the anchor nail.

[0029] 2. The two tightening screws can also be used to fine-tune the position of the connecting rod along the length direction, so that the connecting rods of the two anchoring components that are set opposite each other can be aligned along the length direction. This helps to make the tension direction of the anchoring components on the steel strand mesh perpendicular to the length direction of the connecting rods of the anchoring components, which helps to further reduce the deformation of the steel strand mesh.

[0030] 3. After the steel strand mesh is connected to each anchoring component, the tensioning hook can be tightened by rotating the internal threaded sleeve, thus energizing the steel strand mesh. Attached Figure Description

[0037] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0038] This application discloses an earthquake-resistant reinforcement structure for building construction. (See also...) Figure 1 The seismic reinforcement structure for building construction includes a steel strand mesh 1, anchoring components 2, and a polymer mortar layer 3. The anchoring components 2 are used to fix the steel strand mesh 1 to the reinforced area of ​​the building. Both the anchoring components 2 and the steel strand mesh 1 are embedded in the polymer mortar layer 3. In this embodiment, two anchoring components 2 are provided, located on opposite sides of the steel strand mesh 1. In another embodiment, four anchoring components 2 can be provided, corresponding to the four sides of the steel strand mesh 1.

[0039] Reference Figure 2 and Figure 3 The anchoring assembly 2 includes a connecting rod 21 and multiple anchoring nails 22. The connecting rod 21 is anchored to the reinforced area of ​​the building by the multiple anchoring nails 22. The multiple anchoring nails 22 of the anchoring assembly 2 are arranged at intervals along the length direction of the connecting rod 21. Multiple tensioning connectors 23 are equidistantly arranged along the length direction of the connecting rod 21, and the connecting rod 21 is connected to the steel strands of the steel strand mesh 1 through the tensioning connectors 23.

[0040] Referring to Figure X, the connecting rod 21 includes two parallel round rods 211, which are connected by multiple connecting blocks 212. The multiple connecting blocks 212 are equidistantly arranged along the length of the connecting rod 21, and the gap between the two round rods 211 serves as a connecting groove 213. Anchor pins 22 are rotatably fitted with circular plates 24, and the anchor pins 22 are connected to the connecting rods 21 through the circular plates 24. The circular plates 24 and the anchor pins 22 are eccentrically positioned. The outer circumferential surface of the circular plates 24 is provided with an annular groove 241, and the groove wall of the annular groove 241 is set as an arc surface adapted to the round rods 211. The circular plates 24 are engaged between the two round rods 211 through the annular groove 241, so that the circular plates 24 and the connecting groove 213 form a sliding connection along the length of the connecting groove 213.

[0041] Because the circular plate 24 and the anchor nail 22 are eccentrically positioned, and the circular plate 24 can slide along the connecting groove 213, when there is a deviation in the relative position between the anchor holes, the circular plate 24 of the anchor assembly 2 can rotate around the anchor nail 22 and slide relative to the connecting rod 21 to adapt to the installation position of the anchor nail 22.

[0042] Reference Figure 2 and Figure 3Two connecting blocks 212 located at both ends of the connecting rod 21 are defined as end connecting blocks 2121. Each end connecting block 2121 is threaded with a tightening screw 25, which is parallel to the round rod 211 and abuts against the outer circumferential surface of the round plate 24. When the two tightening screws 25 abut against the corresponding round plates 24, the position of the connecting rod 21 is restricted, thus stabilizing its position. Furthermore, by adjusting the tightening screws 25, the position of the connecting rod 21 can be fine-tuned, thereby aligning the two opposing anchoring components 2 as much as possible to reduce deformation of the steel strand mesh 1 under tension.

[0043] Reference Figure 2 The connecting rod 21 is provided with multiple wire loops 26, which are alternately arranged with the circular plate 24 along the length of the connecting rod 21. The wire loop 26 is formed by winding a wire around the connecting rod 21 and then twisting the two ends of the wire together. The part where the two ends of the wire are connected serves as the twisted connection part 261 of the wire loop 26. The wire loop 26 is used to force the two circular rods 211 to move closer to each other to clamp the circular plate 24.

[0044] Reference Figure 2 and Figure 4 The tensioning connector 23 is connected to one of the two round rods 211 of the connecting rod 21, closer to the steel strand mesh 1. The tensioning connector 23 includes a connecting hook 231 and an internal threaded sleeve 232. One end of the internal threaded sleeve 232 is rotatably connected to the connecting rod 21. The rotation center line between the internal threaded sleeve 232 and the connecting rod 21 coincides with the center line of the internal threaded sleeve 232. The tensioning connector 23 connects to the steel strand mesh 1 through the connecting hook 231. The ends of the steel strands in the steel strand mesh 1 are wrapped and tied to form a collar 11. The collar 11 is hooked by the connecting hook 231. One end of the connecting hook 231 is provided with a threaded rod 2311, which is threadedly connected to the internal threaded sleeve 232.

[0045] Reference Figure 3 The internal threaded sleeve 232 has multiple through holes 2321. The center line of the through holes 2321 is coplanar with the center line of the internal threaded sleeve 232. The through holes 2321 simultaneously penetrate both opposite sides of the internal threaded sleeve 232. The multiple through holes 2321 are distributed at intervals along the circumference of the internal threaded sleeve 232 and at intervals along the length of the internal threaded sleeve 232.

[0046] After the steel strand mesh 1 is connected by the anchoring assembly 2, a rod-shaped tool is used to apply torque to the internal threaded sleeve 232 through the through hole 2321, causing the internal threaded sleeve 232 to rotate. When the rod-shaped tool is obstructed by the building surface, it is pulled out and inserted into another through hole 2321 to continue rotating the internal threaded sleeve 232 until the tensioning connector 23 tightens the steel strand mesh 1. During the construction of the polymer mortar layer 3, the polymer mortar can enter the inside of the internal threaded sleeve 232 through the through hole 2321. After the polymer mortar inside the internal threaded sleeve 232 solidifies, it can improve the stability of the connection between the internal threaded sleeve 232 and the threaded rod 2311.

[0047] When the tensioning connector 23 tightens the steel strand mesh 1, the tensioning connector 23 is subjected to a reverse force. In order to reduce the deformation of the connecting hook 231 of the tensioning connector 23 under the reverse tension of the steel strand mesh 1, the following settings are made: When the connecting hook 231 is hooked to the steel strand mesh 1, the hook opening of the connecting hook 231 faces the building. The end of the connecting hook 231 away from the threaded rod 2311 extends a straight rod 2312, which is parallel to the threaded rod 2311. The straight rod 2312 is used to abut against the reinforced area of ​​the building, so that the building hinders the large deformation of the hook opening of the connecting hook 231.

[0048] Reference Figure 2 Multiple internal threaded sleeves 232 of the anchoring component 2 are connected by a limiting steel wire 27, which passes through a through hole 2321 of each internal threaded sleeve 232 in sequence. The limiting steel wire 27 can prevent the internal threaded sleeve 232 from rotating around its own axis, thereby reducing the possibility of the internal threaded sleeve 232 loosening and helping to keep the tensioning hook 23 of the anchoring component 2 taut over the steel strand mesh 1.

[0049] The implementation principle of the seismic reinforcement structure for building construction in this application embodiment is as follows: During the construction of the seismic reinforcement structure, anchoring holes for installing anchoring nails 22 are first drilled on the building surface at predetermined positions. Then, the anchoring nails 22 of the anchoring assembly 2 are anchored in the reinforced area of ​​the building. When there is a deviation in the relative position between the anchoring holes, the circular plate 24 of the anchoring assembly 2 can rotate around the anchoring nails 22 and slide relative to the connecting rod 21 to adapt to the installation position of the anchoring nails 22.

[0050] After the anchoring components 2 are installed, the steel strand mesh 1 is connected and fixed to each anchoring component 2, so that the steel strand mesh 1 is hung in the reinforced area of ​​the building. After the steel strands are hung, the tightening screws 25 of the two anchoring components 2 are adjusted to keep the two anchoring components 2 as aligned as possible. Then, the steel strand mesh 1 is tensioned by rotating the internal threaded sleeves 232 of the two anchoring components 2. After the steel strand mesh 1 is installed and tensioned, the different parts of the anchoring components 2 can be welded and fixed as needed to further strengthen the structure of the anchoring components 2.

[0051] The anchoring component 2 connects the steel strands of the steel strand mesh 1 through the tensioning hanger 23. The arrangement spacing of the tensioning hanger 23 is not affected by the positional deviation of the anchoring holes, which helps to make the tension of the steel strand mesh 1 more uniform and makes the reinforcement effect of the steel strand mesh 1 less affected.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
