Description

Technical Field

[0001] The utility model belongs to the field of wall reinforcement, in particular to a brick-concrete building wall reinforcement structure. Background Art

[0002] With the continuous development of the construction industry, the number of houses is increasing. In addition to new construction and renovation, there is also a large amount of reinforcement work on old buildings. Currently, a large number of buildings need to be reinforced and renovated. Among the houses to be reinforced and renovated, there are a large number of brick-concrete buildings. For the renovation of brick-concrete walls, reinforced concrete is currently used to reinforce the facade. The reinforced concrete reinforcement process is very complicated. At the same time, reinforced concrete will also cause excessive damage to the facade. The reinforcement strength and seismic resistance of the reinforced concrete structure are not ideal, and the integrity and deformation resistance of the wall are also not ideal. Therefore, a reinforcement structure that can solve the above problems is needed.

[0003] For example, patent CN202322118206.1 uses galvanized steel plates and angle steels in combination with bolts for support and reinforcement. The wall is connected and supported to the existing wall by the steel plates and angle steels, and is fixed by the existing thick wall. This method requires the existing high-strength wall as support, and this method can only support and prevent the existing wall from tipping over, and cannot solve the inherent fragmentation and damage of the wall. Therefore, there is no significant enhancement in the seismic performance. Now there is a need for a structure that can make up for the shortcomings of the existing reinforcement structure. Utility Model Content

[0004] The utility model provides a brick-concrete building wall reinforcement structure with good seismic resistance, high reinforcement integrity and strength, and is particularly suitable for reinforcing the walls of old brick-concrete buildings. The technical problem to be solved is that the current brick-concrete building wall reinforcement process is complicated and has poor integrity and deformation resistance, resulting in poor seismic performance.

[0005] The technical solution adopted by this utility model is:

[0006] A brick-concrete building wall reinforcement structure includes a concrete reinforcement layer, purlins, rafters, hanging nails, connecting nails and stripping nails. The concrete reinforcement layer is covered on the outside of the wall. Purlins or rafters are arranged on the top of the concrete reinforcement layer. The purlins and rafters are perpendicular to each other and fixedly connected. The ends of the purlins and rafters are fixedly connected to the concrete reinforcement layer.

[0007] Furthermore, the concrete reinforcement layer adopts high-ductility concrete, and the concrete reinforcement layer also includes a triangular reinforcement structure, a square reinforcement structure and a horizontal reinforcement structure. When the concrete reinforcement layer is located at the door frame or window frame, it is separated from the door frame or window frame by a certain distance. The triangular reinforcement structure is a concrete reinforcement layer with a smear layer triangle. The triangular reinforcement structure is a triangular structure in which the middle of the concrete reinforcement layer on both sides of the door frame or window frame is inclined toward the bottom of the wall. The horizontal reinforcement structure is the concrete reinforcement layer where the door frame is located. The concrete reinforcement layer is located in the lower half of the door frame. The concrete reinforcement layer is connected to the door frame, and the corners of the polygon formed by the concrete reinforcement layer are set to be chamfered.

[0008] Furthermore, the concrete reinforcement layer is located at the window frame and is a polygon with the same shape surrounding the window frame. The polygon of the concrete reinforcement layer surrounding the window frame is located at the corner of the window frame and is arranged in a chamfered shape.

[0009] Furthermore, a triangular reinforcement structure is provided below the window frame surrounded by the concrete reinforcement layer and closest to the wall bottom.

[0010] Furthermore, the concrete reinforcement layer is located at the door frame and is a polygon with the same shape surrounding the door frame, and the polygon of the concrete reinforcement layer surrounding the door frame is arranged in a chamfered shape at the corner of the door frame.

[0011] Furthermore, the concrete reinforcement layer is located in the lower half of the door frame and is provided with a triangular reinforcement structure or a horizontal reinforcement structure.

[0012] Furthermore, the concrete reinforcement structure is located on the wall without doors and windows and adopts a grid-like structure. The top of the grid-like structure is horizontally connected as a whole. A triangular reinforcement structure or a square reinforcement structure is set at the lower end of the grid-like structure. The square reinforcement structure is the bottom end of the grid-like structure horizontally connected as a whole, and the middle polygonal corner of the grid is set to a chamfered shape.

[0013] Furthermore, the purlins are mounted on the top of the wall, with nails installed at the ends of the purlins, and wire mesh is hung on both ends of the nails. The rafters are also mounted on the ends of the rafters, and wire mesh is hung on both ends of the nails. The rafters and purlins are connected by nails, and the wire mesh is installed inside the concrete reinforcement layer. The purlins are cylindrical, and the rafters are quadrangular.

[0014] Furthermore, the hanging nail includes a hanging rod and a nail head, and both ends of the hanging rod are fixedly connected to the nail head.

[0015] Furthermore, the parts of the concrete reinforcement layer located on both sides of the wall are connected by connecting nails, and the connecting nails penetrate the wall, and both ends of the connecting nails are bent.

[0016] The above structure has the following beneficial effects:

[0017] 1. The use of high-ductility concrete instead of ordinary concrete and the use of connecting nails for connection overcomes the problem of unsatisfactory seismic performance of the wall in the traditional concrete connection process, thereby improving the integrity of the reinforced wall, greatly enhancing the seismic performance of the wall, and greatly improving the overall structural strength of the wall.

[0018] 2. Since there are different concrete reinforcement layer structures for window frames, door frames and walls without doors and windows, the problem of material waste or insufficient strength of existing concrete reinforcement layers is overcome, thereby improving the structural strength of the reinforcement and reducing material consumption.

[0019] 3. By using purlins and rafters to fix the walls, the problem of multiple indoor walls collapsing can be overcome, thereby greatly improving the overall structural strength of the house and reinforcing the roof. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0033] like Figure 1-10 As shown:

[0034] A brick-concrete building wall reinforcement structure includes a concrete reinforcement layer 1, purlins 2, rafters 3, hanging nails 4, connecting nails 5, and stripping nails 6. The concrete reinforcement layer 1 is coated on the exterior of the wall. Purlins 2 or rafters 3 are arranged on top of the concrete reinforcement layer 1. The purlins 2 and rafters 3 are perpendicular to each other and fixedly connected. The ends of the purlins 2 and rafters 3 are fixedly connected to the concrete reinforcement layer 1. A steel mesh can be provided inside the concrete reinforcement layer 1 to enhance its integrity. The purlins 2 and rafters 3 are fixed perpendicularly to each other above the four walls of the room. The concrete reinforcement layer 1 connects the walls into a whole, preventing them from breaking and greatly improving their integrity and structural strength. The purlins 2 and rafters connect the four walls of the house into a whole, preventing the walls from collapsing. At the same time, they provide support and reinforcement for the roof, preventing roof collapse and enhancing the house reinforcement effect.

[0035] The concrete reinforcement layer 1 is made of high-ductility concrete. High-ductility concrete has better structural properties than ordinary concrete and can better increase the strength of the reinforced structure. The concrete reinforcement layer 1 also includes a triangular reinforcement structure 9, a square reinforcement structure 10 and a horizontal reinforcement structure 11. When the concrete reinforcement layer 1 is located at the door frame or window frame, it is spaced a certain distance from the door frame or window frame. The triangular reinforcement structure 9 is a concrete reinforcement layer 1 in the shape of a smear layer triangle. The triangular reinforcement structure 9 is a concrete reinforcement layer 1 on both sides of the door frame or window frame, which is inclined toward the bottom of the wall to form a triangular structure. The horizontal reinforcement structure 11 is the concrete reinforcement layer 1 at the door frame. The concrete reinforcement layer 1 is located in the lower half of the door frame and is connected to the door frame. The corners of the polygon formed by the concrete reinforcement layer 1 are set to be chamfered. The chamfered structure can make construction more convenient and avoid the problem of easy damage to the corners.

[0036] When reinforcing a single-sided wall, the reinforcing coating structure on the inside and outside of the wall is the same and symmetrical, and the reinforced concrete on the inside and outside is connected by a concrete reinforcement layer 1 at both ends of the wall to form a fully enclosed concrete reinforcement layer. Since the concrete reinforcement layers 1 on the inside and outside of the wall are connected as one, the overall structural strength is better. At the same time, the structure of the concrete reinforcement layer is the same and symmetrical relative to the wall. The overall force of the reinforced structure is uniform, and there is no obvious stress concentration point, which improves the integrity and seismic performance of the wall.

[0037] Window frame position reinforcement:

[0038] The concrete reinforcement layer 1 is located at the window frame and is a polygon with the same shape surrounding the window frame. The polygon of the concrete reinforcement layer 1 surrounding the window frame is located at the corner of the window frame and is set to a chamfered shape.

[0039] A triangular reinforcement structure 9 is provided below the window frame closest to the wall bottom, which is surrounded by the concrete reinforcement layer 1. The triangular structure 9 is inclined downward from both sides of the window frame, which effectively reduces the use of materials while ensuring structural strength compared to the full surrounding method.

[0040] Door frame reinforcement:

[0041] The concrete reinforcement layer 1 is located at the door frame and is a polygon that surrounds the door frame and has the same shape. The polygon of the concrete reinforcement layer 1 surrounding the door frame is located at the corner of the door frame and is set to a chamfered shape.

[0042] The concrete reinforcement layer 1 is located in the lower half of the door frame, and a triangular reinforcement structure 9 or a horizontal reinforcement structure 11 is set. Experiments have found that the unreinforced part of the door frame is prone to cracking. By reinforcing the lower half of the door frame with a triangular structure or a horizontal reinforcement structure, this lower half of the door frame is prevented from cracking during earthquakes, ensuring the overall structural stability of the house and preventing danger from small details.

[0043] Reinforcement of walls without doors and windows:

[0044] The concrete reinforcement layer 1 is located on the wall without doors and windows and adopts a grid-like structure. The top of the grid-like structure is horizontally connected as a whole. The lower end of the grid-like structure is provided with a triangular reinforcement structure 9 or a square reinforcement structure 10. The square reinforcement structure 10 is horizontally connected to the bottom end of the grid-like structure as a whole, and the middle polygonal corner of the grid is chamfered. To save materials, grid-like reinforcement is usually used, but it has the same problem as door frames: damage will occur from the lower half of the grid gap. Therefore, a structure with a grid structure connected above and below avoids damage to the wall without doors and windows, improves the overall strength of the structure, and enhances the earthquake resistance.

[0045] Roof and wall reinforcement:

[0046] The purlin 2 is clamped on the top of the wall, and a nail 4 is set at the end of the purlin 2, and a wire mesh is hung at both ends of the nail 4. The rafter 3 is also set at the end of the nail 4, and a wire mesh is hung at both ends of the nail. The rafter 3 and the purlin 2 are connected by nails 6, and the wire mesh is set inside the concrete reinforcement layer 1. By hanging the wire mesh, the purlin 2 and the rafter 3 can better connect with the high-ductility concrete, and the more convenient hanging of the wire mesh facilitates the integration of the high-ductility concrete, improving the overall structural strength. Regardless of whether the roof has a working surface, reinforcement work can be conveniently carried out. After the purlin 2 and the rafter 3 are connected by nails, the four walls of the house can be connected as a whole, and the roof can also be supported and reinforced, effectively improving the overall safety and structural strength of the house.

[0047] The hanging nail 4 includes a hanging rod 7 and a nail head 8, and both ends of the hanging rod 7 are fixedly connected to the nail head 8. The hanging rod 7 penetrates the purlin 2 or the rafter 3, which is convenient for hanging the wire mesh. The nail head 8 is welded to the two ends of the hanging rod 7, and the nail head 8 avoids the hanging part from falling off.

[0048] The concrete reinforcement layer 1, located on either side of the wall, is connected by connecting nails 5, which penetrate the wall and have bends at both ends. The bends at both ends of the connecting nails 5 are in opposite directions. Connecting nails 5 connect the high-ductility concrete slabs on either side of the wall into a single unit, improving the connection between the concrete reinforcement layer 1 and the wall, better integrating the reinforced structure with the existing building, forming a more stable whole and enhancing the reinforcement effect. The bends enhance the connection strength while facilitating the installation and positioning of the wire mesh.

[0049] How this example works:

[0050] During use, holes are first drilled in the wall that needs to be reinforced, and connecting nails 5 are inserted into the drilled holes. The two ends of the connecting nails 5 are bent or welded into an elbow, and wire mesh is set on both sides of the wall using the connecting nails 5. Purlins 2 or rafters 3 are placed above the wall. The purlins 2 and rafters 3 are perpendicular to each other, and the purlins 2 and rafters 3 are connected as a whole by nails 6. A plurality of purlins 2 and rafters 3 are arranged side by side. The mesh structure formed in this way can well connect and fix the wall surface inside the house from above as a whole, and at the same time provide support and reinforcement for the roof. The two ends of the purlin 2 are located above the concrete reinforcement layer 1 and are installed with hanging nails 4. The hanging nails 4 are hung with wire mesh to facilitate connecting the purlin 2 and the concrete reinforcement layer 1 as a whole, so that the wall reinforcement structure The wall and roof are connected to form a whole, and wire mesh is also hung on the two ends of the rafter 3 through the nails 4 to connect the vertical walls into a whole. In this way, the four walls and the roof of the house form a complete reinforcement frame through the reinforcement structure, which can form a solid whole in the face of an earthquake, avoiding the collapse of multiple walls or the collapse of the roof, so that the house forms a new support frame through the external reinforcement structure, ensuring the reinforcement effect of the house. The concrete reinforcement layer 1 at the corner of the wall uses a complete strip to connect the two walls to avoid the splitting of the two walls at the corner, and can better connect multiple walls into a whole. If the wall structure requires a large supporting force, an inclined concrete structure can be applied between the wall and the ground for reinforcement to increase the supporting force.

[0051] The concrete reinforcement layer 1 uses high-ductility concrete. High-ductility concrete has good structural strength and damage resistance, and is also called bendable concrete. Therefore, the wall will not break and collapse when it exceeds the tolerance like ordinary reinforced structures. Instead, it will produce slight deformation. With the help of deformation and the tension of the internal wire mesh, the wall remains intact. Even if it collapses, a triangular stable area can be formed with the help of the intact wall, which increases the survival rate of people and makes the reinforced house safer.
