Description

Technical Field

[0001] The present application relates to the technical field of building wall reinforcement, and in particular to an earthquake-resistant reinforcement structure for a house. Background Art

[0002] As the age of houses in old communities or certain specific buildings increases, due to their own settlement effects and the influence of crustal activities, cracks, extrusion deformation and facade peeling will occur in the walls of the houses during use. Therefore, it is necessary to reinforce the walls of the old buildings to improve the safety of the buildings and extend their service life.

[0003] Common building wall reinforcement measures include wall grouting and the construction of seismic-resistant walls. Wall grouting is mostly used to reinforce walls that have initially cracked. For building walls with wider cracks or severe settlement, the reinforcement method of adding seismic-resistant walls is usually adopted. That is, seismic-resistant walls are built on the outside or both sides of the old building walls to prevent further damage to the walls and enhance the building walls' ability to bear loads.

[0004] A common earthquake-resistant wall is one that's constructed by re-molding and pouring concrete outside the existing wall, creating a single, integrated structure. This strengthens the building's ability to resist deformation. Simply pouring concrete outside the existing wall, once hardened, provides strong compressive strength, but its tensile strength needs improvement. Summary of the Invention

[0005] In order to improve the tensile strength of the earthquake-resistant wall built outside the old wall, the present application provides a house earthquake-resistant reinforcement structure.

[0006] This application provides a building earthquake-resistant reinforcement structure, which adopts the following technical solutions:

[0007] A seismic reinforcement structure for a house comprises a positioning frame, a steel mesh is installed in the positioning frame, cross braces are provided on both sides of the positioning frame, the ends of the cross braces are installed at the corners of the positioning frame, reinforcement braces are provided on the sides of the cross braces on both sides of the positioning frame that are away from each other, two reinforcement braces and two cross braces are provided in a one-to-one correspondence, the reinforcement braces are located at the intersection of the corresponding cross braces, limiting grooves are provided on the reinforcement braces, the cross braces are installed in the corresponding limiting grooves, the steel mesh is located between the two reinforcement braces, a connecting mechanism is provided on the reinforcement brace, the two reinforcement braces are connected by the connecting mechanism, the positioning frame, the steel mesh, the cross brace and the reinforcement brace are all buried in the seismic wall concrete of the building's exterior wall.

[0008] With this technical solution, the steel mesh embedded within the concrete of the seismic wall enhances the wall's tensile strength due to the mesh's tensioning action. It shares the load-bearing capacity with the concrete, thereby improving the wall's load-bearing capacity. The difference between a single-layer steel mesh and conventional designs that embed structural steel within the wall is that it meets the wall's tensile strength requirements while also reducing the wall's deadweight, thereby reducing the load on the wall's substructure.

[0009] Furthermore, the steel mesh is installed within the positioning frame. This, on the one hand, facilitates the erection of the steel mesh for pouring the seismic wall concrete, reducing the possibility of the steel mesh shifting during the concrete pouring process. Furthermore, the positioning frame itself possesses a certain degree of rigidity, and once embedded within the seismic wall concrete, it increases the rigidity of the seismic wall. Furthermore, the positioning frame, supported by the cross braces and reinforcement braces, forms a triangular support structure with the cross braces, further strengthening the rigidity of the positioning frame.

[0010] In a preferred example, the present application can be further configured as follows: a steel wire rope is wound around the cross brace, both of the cross braces are wound in the steel wire rope, the steel wire rope passes through the grid of the steel mesh, and the steel wire rope and the steel bars on the steel mesh are intertwined with each other.

[0011] Through the above technical solution, the steel wire ropes bundle the steel mesh and the two cross braces into a whole, thereby strengthening the integrity of the cross braces and the steel mesh. The tensile capacity of the steel mesh is strengthened by the cross braces and the steel wire ropes, thereby further increasing the tensile capacity of the seismic wall.

[0012] In a preferred example, the present application can be further configured as follows: a circular ring is installed on the cross support, and the steel wire rope passes through the circular ring.

[0013] Through the above technical solution, since the steel wire rope passes through the circular ring, on the one hand, the possibility of the steel wire rope being displaced relative to the cross brace is reduced under the limiting effect of the circular ring. On the other hand, the limiting effect of the circular ring on the steel wire rope can reduce the winding radius of the steel wire rope, thereby reducing the consumption of the steel wire rope and reducing the construction cost of the seismic wall.

[0014] In a preferred example, the present application can be further configured as follows: a connecting shaft is provided on the circular ring, the circular ring is mounted on the cross brace via the connecting shaft, a connecting hole is provided on the cross brace, and the connecting shaft and the inner wall of the connecting hole are threadedly connected.

[0015] With the above technical solution, since the ring is mounted on the cross brace via the connecting shaft, the operator can rotate the connecting shaft to change the orientation of the ring while threading the wire rope into the ring, making it easier for the operator to thread the wire rope into the ring. This also enables a detachable connection of the ring.

[0016] In a preferred example, the present application can be further configured as follows: the connecting mechanism includes a bolt 1 and a nut, the nut is threadedly connected to the bolt 1, and a through hole 1 is provided on the reinforcing support for the bolt 1 to pass through.

[0017] Through the above technical solution, the two reinforcement braces are connected into a whole by bolts and nuts, thereby strengthening the integrity of the reinforcement brace, cross brace and steel mesh.

[0018] In a preferred example, the present application can be further configured as follows: the end of the wire rope is fixedly connected to a connecting tube, a second through hole is opened on the connecting tube, the first bolt is passed through the second through hole, and the connecting tube is located between the two reinforcement supports.

[0019] Through the above technical solution, before the operator winds the wire rope, the connecting tube is first put on the bolt one, that is, the bolt one is passed through the connecting hole of the connecting tube, and then the wire rope is passed through. The bolt one exerts a restraining effect on the connecting tube, reducing the possibility of the wire rope sliding along the length direction of the cross brace, and can also keep the wire rope in a taut state, which is equivalent to applying a certain prestress to the wire rope, thereby improving the load-bearing capacity of the wire rope.

[0020] In a preferred example, the present application can be further configured as follows: the length of the connecting tube is equal to the distance between the two reinforcement supports.

[0021] With the above technical solution, since the length of the connecting tube is equal to the distance between the two reinforcing supports, both ends of the connecting tube can abut against the two reinforcing supports, thereby reducing the possibility of the connecting tube sliding along the length direction of the bolt.

[0022] In a preferred example, the present application can be further configured as follows: the positioning frame includes an installation frame one and an installation frame two, both of which are provided with installation grooves, the steel mesh is installed in the installation grooves, and a limiting rod is provided on the inner wall of the installation groove, and the limiting rod passes through the grid of the steel mesh.

[0023] Through the above technical solution, the operator places the steel mesh in the installation groove, allows the limit rod to pass through the grid of the steel mesh, and then fastens the installation frame 1 to the installation frame 2 to complete the installation of the steel mesh on the limit frame.

[0024] In a preferred example, the present application can be further configured as follows: expansion bolts are installed on the cross brace, three through holes are provided on the cross brace for the expansion bolts to pass through, four through holes are provided on both the first and second mounting frames for the expansion bolts to pass through, mounting holes are provided on the exterior wall of the building, and sleeves are provided in the mounting holes for the expansion bolts to be installed.

[0025] Through the above technical solution, the operator passes the expansion bolts through through hole three and through hole four in sequence, so that the expansion bolts are fixed in the sleeve, so that the steel mesh, cross brace, installation frame one and installation frame two are all fixed on the exterior wall of the building, so as to facilitate the later pouring of earthquake-resistant wall concrete.

[0026] In a preferred example, the present application can be further configured as follows: a connecting ring is provided on the steel wire rope, the expansion bolt is passed through the connecting ring, and the connecting ring is located between the expansion bolt and the installation frame.

[0027] With the above technical solution, since the expansion bolt passes through the connecting ring, the two ends of the wire rope are respectively limited by bolt 1 and the expansion bolt, which reduces the possibility of the wire rope sliding relative to the cross brace.

[0028] In summary, this application has the following beneficial technical effects:

[0029] 1. Seismic wall concrete is mainly used to bear vertical loads, while the steel mesh inside the seismic wall concrete mainly bears the tension generated by building settlement and crustal movement, thereby improving the ability of seismic wall concrete to withstand various stresses, and further extending the service life of the building;

[0030] 2. The steel wire ropes bind the steel mesh and two cross braces into a whole, which strengthens the integrity of the cross braces and steel mesh. The cross braces and steel wire ropes strengthen the tensile strength of the steel mesh, which further increases the tensile strength of the seismic wall.

[0031] 3. The two ends of the wire rope are limited by bolt 1 and expansion bolt respectively, which reduces the possibility of the wire rope sliding relative to the cross brace;

[0032] 4. The steel mesh, cross brace and positioning frame are fixed to the building wall through expansion bolts. On the one hand, the operator does not need to support the steel mesh and other structures during the seismic wall formwork process, so as to facilitate the subsequent pouring of seismic wall concrete. On the other hand, it can also reduce the possibility of displacement of structures such as the steel mesh during the concrete pouring process. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The following is combined with Figure 1 -Attached Figure 6 This application is described in further detail.

[0042] An embodiment of the present application discloses an earthquake-resistant reinforcement structure for a house.

[0043] Refer to the attached Figure 1 and attached Figure 2 As shown, a building seismic reinforcement structure includes a seismic wall 102 cast outside a building exterior wall 111. Seismic wall 102 is formed by roughening the exterior surface of the existing building exterior wall 111 and then pouring concrete. A positioning frame 1, a steel mesh 101, cross braces 2, reinforcement braces 3, and steel cables 21 are embedded within the concrete of seismic wall 102. The embedded steel mesh 101 enhances the tensile strength of seismic wall 102 due to the tensioning action of the steel mesh 101.

[0044] The above structure embedded in the earthquake-resistant wall 102 will be described in detail below.

[0045] Refer to the attached Figure 2 and attached Figure 3 As shown, the positioning frame 1 includes a vertically arranged installation frame 11 and an installation frame 2 12, and the installation frame 11 and the installation frame 2 12 are both arranged parallel to the wall. The installation frame 11 and the installation frame 2 12 are each provided with an installation groove 121 on one side close to each other, and the wire mesh is arranged in the installation groove 121 and is located between the installation frame 11 and the installation frame 2 12. A plurality of limiting rods 122 are fixedly connected to the inner wall of one of the installation grooves 121, and each limiting rod 122 passes through the grid of the steel mesh 101. Under the limiting action of the limiting rod 122, the tension of the steel mesh 101 can be maintained.

[0046] Refer to the attached Figure 2 and attached Figure 4 As shown, cross braces 2 are provided on both sides of the positioning frame 1, that is, a cross brace 2 is provided on the side where the mounting frame 1 11 and the mounting frame 2 12 are away from each other. The cross braces 2 are made of steel plates, and the ends of the two cross braces 2 are respectively installed at the corners of the mounting frame 1 11 and the mounting frame 2 12. A reinforcing brace 3 is provided on the side where the mounting frame 1 11 and the mounting frame 2 12 are away from each other. The two reinforcing braces 3 and the two cross braces 2 are arranged one-to-one. The reinforcing braces 3 are in the shape of a "cross" and are located at the intersection of the corresponding cross braces 2. The reinforcing braces 3 are provided with limiting grooves 31 for accommodating the cross braces 2. The cross braces 2 are installed in the limiting grooves 31, and the steel mesh 101 is located between the two reinforcing braces 3. Under the support of the cross braces 2, the positioning frame 1 and the cross braces 2 form multiple triangular support structures, further strengthening the rigidity of the positioning frame 1. The cross braces 2, under the support of the reinforcing braces 3, reduce the possibility of deformation of the cross braces 2.

[0047] Refer to the attached Figure 2 and attached Figure 5As shown, four expansion bolts 6 are installed on the cross brace 2, and the four expansion bolts 6 are respectively located at the four ends of the cross brace 2. A through hole three 24 is opened on the cross brace 2 for the expansion bolts 6 to pass through. A through hole four 123 is opened on the mounting frame 11 and the mounting frame 2 12 for the expansion bolts 6 to pass through. A mounting hole 7 is opened on the building exterior wall 111, and a sleeve 71 for installing the expansion bolt 6 is provided in the mounting hole 7. The sleeve 71 is bonded to the inner wall of the mounting hole 7 by a sealant. The operator passes the expansion bolt 6 through the through hole three 24 and the through hole four 123 in sequence, so that the expansion bolt 6 is fixed in the sleeve 71, so that the steel mesh 101, the cross brace 2, the installation frame 11 and the installation frame 2 12 are all fixed on the exterior wall 111 of the building. On the one hand, the operator does not need to support the steel mesh 101 and other structures during the process of erecting the formwork of the seismic wall 102, so as to facilitate the subsequent pouring of the concrete of the seismic wall 102. On the other hand, it can also prevent the steel mesh 101 and other structures from being displaced during the concrete pouring process.

[0048] Refer to the attached Figure 2 and attached Figure 4 As shown, a connecting mechanism 4 is provided on the reinforcement support 3, and the two reinforcement supports 3 are connected by the connecting mechanism 4. The connecting mechanism 4 includes a bolt 41 and a nut 42. The nut 42 is threadedly connected to the bolt 41. A through hole 32 for the bolt 41 to pass through is provided on the reinforcement support 3. The bolt 41 passes through the through hole 32 on the two reinforcement supports 3 and is threadedly connected to the nut 42, completing the connection of the two reinforcement supports 3, thereby increasing the integrity of the reinforcement support 3, the cross support 2 and the steel mesh 101.

[0049] Refer to the attached Figure 2 , Attachment Figure 4 And attached Figure 5 As shown, a steel wire rope 21 is spirally wound around the cross brace 2. Both cross braces 2 are wrapped around the steel wire rope 21. The steel wire rope 21 passes through the mesh of the steel mesh 101, and the steel wire rope 21 and the steel bars on the steel mesh 101 are intertwined. The cross brace 2 is provided with a plurality of connection holes 23, each of which is threadedly connected to a connecting shaft 221. The connecting shaft 221 is fixedly connected to a circular ring 22 at one end away from the cross brace 2. The steel wire rope 21 is inserted into the circular ring 22. When the operator inserts the steel wire rope 21 into the circular ring 22, the operator can rotate the connecting shaft 221 to change the direction of the circular ring 22, thereby facilitating the insertion of the steel wire rope 21 into the circular ring 22.

[0050] Refer to the attached Figure 4 and attached Figure 6As shown, a connecting tube 5 is welded and fixed to one end of the steel wire rope 21, and a through hole 2 51 is opened through the connecting tube 5. A bolt 1 41 is passed through the through hole 2 51. The connecting tube 5 is located between the two reinforcement supports 3. The length of the connecting tube 5 is equal to the distance between the two reinforcement supports 3. In this way, the two ends of the connecting tube 5 can abut against the two reinforcement supports 3, which reduces the possibility of the connecting tube 5 sliding along the length direction of the bolt 1 41.

[0051] Refer to the attached Figure 4 and attached Figure 6 As shown, the other end of the wire rope 21 is welded to a connecting ring 211, and the expansion bolt 6 is inserted into the connecting ring 211. The connecting ring 211 is located between the expansion bolt 6 and the mounting frame 11. The operator can pre-thread the wire rope 21 through the plurality of circular rings 22. After the wire rope 21 is wound, the two ends of the wire rope 21 are welded to the connecting tube 5 and the connecting ring 211. The two ends of the wire rope 21 are respectively limited by the bolt 41 and the expansion bolt 6, which reduces the possibility of the wire rope 21 slipping relative to the cross brace 2.

[0052] The implementation principle of this embodiment is: when the operator needs to reinforce the building exterior wall 111, the building exterior wall 111 is first roughened to make the building exterior wall 111 present a rough surface, and then rinsed clean.

[0053] Then, a mounting hole 7 is opened on the building exterior wall 111 , and a sleeve 71 for mounting the expansion bolt 6 is bonded into the mounting hole 7 .

[0054] Next, the cross brace 2 is installed on the positioning frame 1 , and the reinforcement brace 3 is installed on the cross brace 2 , and the two reinforcement braces 3 are fixed by bolts 41 and nuts 42 .

[0055] Next, the steel wire rope 21 is wound around the cross brace 2 , and both ends of the steel wire rope 21 are welded and fixed to the connecting tube 5 and the connecting ring 211 respectively.

[0056] Finally, the expansion bolt 6 is passed through the ring 22, the cross brace 2, the mounting frame 11 and the mounting frame 2 12 so that the expansion bolt 6 is installed in the sleeve 71, and the concrete of the seismic wall 102 is poured in a formwork so that the above structures are all buried in the concrete of the seismic wall 102.

[0057] To sum up, the concrete of the seismic wall 102 is mainly used to bear vertical loads, and the steel mesh 101, positioning frame 1 and cross brace 2 inside the seismic wall 102 concrete mainly bear the tension generated by building settlement and crustal movement, thereby improving the ability of the seismic wall 102 concrete to withstand various stresses, and further improving the service life of the building.

[0058] The embodiments of this specific implementation method are all preferred embodiments of the present application and are not intended to limit the scope of protection of the present application in turn. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
