Description

Technical Field

[0001] The present application relates to the field of construction technology, and in particular to a brick-concrete wall structure. Background Art

[0002] A type of brick-concrete structure, in which the vertical load-bearing structure is a brick wall built of bricks, which bears the vertical load of the building.

[0003] Most early buildings were built with brick-concrete structures. However, due to the shape and strength limitations of the bricks in the walls, the bearing capacity of the walls was weak, resulting in more cracks on the periphery of the walls and weaker seismic performance.

[0004] To improve the bearing capacity and seismic resistance of brick-concrete structures, brick walls within these structures need to be reinforced. Conventional technology involves adding reinforcement columns to the exterior of the brick walls, using them to share the vertical load and thereby improve the wall's bearing capacity and seismic resistance. The reinforcement columns are constructed as follows: First, a steel cage is installed outside the brick wall; then, the columns are constructed through formwork support and concrete pouring.

[0005] However, due to the lack of connectivity between the newly added reinforcement columns and the original brick walls, it is difficult for the newly added reinforcement columns to work synergistically with the original brick walls; the original brick walls still bear most of the vertical loads, making it difficult to play the role of the reinforcement columns. The bearing capacity of the walls in the brick-concrete structure is slightly improved, and the reinforcement effect of the walls in the brick-concrete structure is poor. Utility Model Content

[0006] In order to improve the reinforcement effect of the wall in the brick-concrete structure, the present application provides a brick-concrete wall structure.

[0007] This application provides a brick-concrete wall structure, which adopts the following technical solution:

[0008] A brick-concrete wall structure is fixedly arranged between a lower floor slab and an upper floor slab; the brick-concrete wall structure includes a brick wall and reinforcement columns, and the reinforcement columns are arranged at intervals on the outside of the brick wall along the length direction of the brick wall; the reinforcement columns include columns and corbels, and the columns and the corbels are reinforced concrete structures. The columns and the corbels are cast as one piece, the columns are fixedly connected to the brick wall, and the corbels are fixedly connected to the upper floor slab; the brick wall is provided with an accommodating groove on the side close to the upper floor slab, and the accommodating groove is used to accommodate the corbels.

[0009] By adopting the above technical solution, an accommodating groove is opened on the side of the brick wall close to the upper floor slab, so that the corbel part of the reinforcement column is directly set between the brick wall and the upper floor slab; so as to give full play to the synergistic effect of the reinforcement column and the brick wall, so that the reinforcement column can share more vertical loads, thereby improving the bearing capacity and seismic performance of the wall, and improving the reinforcement effect of the wall in the brick-concrete structure.

[0010] Optionally, the reinforcement columns are arranged in pairs on both sides of the brick wall, and the oppositely arranged reinforcement columns are cast in one piece.

[0011] By adopting the above technical solution, when the wall is set inside the building, the reinforcement columns are set in pairs on both sides of the brick wall to further improve the integrity of the reinforcement columns and the brick wall, further improve the bearing capacity and seismic resistance of the wall, and enhance the reinforcement effect of the wall.

[0012] Optionally, it also includes a plurality of tension bolts. The brick wall is provided with mounting holes for the tension bolts to pass through. The tension bolts are buried in the columns on both sides of the brick wall. Along the height direction of the columns, a plurality of the tension bolts are arranged at intervals.

[0013] By adopting the above technical solution, by burying tension bolts in the brick wall and the reinforcement columns on both sides of the brick wall, the connection strength between the brick wall and the reinforcement columns is further improved, thereby further improving the synergy between the brick wall and the reinforcement columns and improving the integrity of the reinforced wall.

[0014] Optionally, it further includes reinforcing steel bars, which are arranged vertically and embedded in the columns, and are tied and fixed with the tension bolts.

[0015] By adopting the above technical solution, processed steel bars are used to fix the tension bolts, so as to further strengthen the tensioning effect of the tension bolts on the two reinforced columns, thereby further improving the integrity of the reinforced wall.

[0016] Optionally, the concrete used to cast the reinforcement column is slightly expansive concrete.

[0017] By adopting the above technical solution, the reinforcement columns are cast with micro-expansive concrete, thereby utilizing the micro-expansion effect of the micro-expansive concrete after solidification and hardening, so that the reinforcement columns are tightly connected with the upper and lower floor slabs, so that the reinforcement columns can fully bear the vertical load, thereby giving full play to the load-bearing function of the wall in the brick-concrete structure.

[0018] Optionally, it also includes an upper connecting steel bar, one end of which is used to be fixed to the upper floor slab anchor bar, and the other end of the lower connecting steel bar is buried in the corbel.

[0019] By adopting the above technical solution, by arranging upper connecting steel bars between the upper floor slab and the corbels of the reinforced columns, the connection strength between the reinforced columns and the upper floor slab is further improved, thereby further improving the seismic performance of the brick-concrete structure.

[0020] Optionally, it further includes a lower connecting steel bar, one end of which is used to be fixed to the lower floor slab anchor bar, and the other end of which is buried in the column.

[0021] By adopting the above technical solution, lower connecting steel bars are set between the lower floor slab and the reinforced columns to improve the connection strength between the lower floor slab and the reinforced columns, thereby further improving the seismic performance of the brick-concrete structure.

[0022] Optionally, tensile strength fibers are embedded in the reinforcement column, and the tensile strength fibers are distributed in the reinforcement column.

[0023] By adopting the above technical solution, tensile strength of the concrete in the reinforced column is improved by mixing tensile fibers into the concrete of the reinforced column, thereby improving the bearing capacity of the reinforced column.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. By creating an accommodating groove on the side of the brick wall close to the upper floor slab, the corbel portion of the reinforcement column is directly set between the brick wall and the upper floor slab; this fully utilizes the synergistic effect of the reinforcement column and the brick wall, allowing the reinforcement column to share more vertical loads, thereby improving the bearing capacity and seismic performance of the wall and enhancing the reinforcement effect of the wall in the brick-concrete structure;

[0026] 2. By embedding tension bolts in the brick wall and the reinforcement columns on both sides of the brick wall, the connection strength between the brick wall and the reinforcement columns is further improved, thereby further enhancing the synergy between the brick wall and the reinforcement columns and improving the integrity of the reinforced wall;

[0027] 3. The reinforcement columns are cast with micro-expansive concrete, making use of the micro-expansion effect of the micro-collision concrete after solidification and hardening, so that the reinforcement columns are closely connected with the upper and lower floor slabs, so that the reinforcement columns can fully bear the vertical load, so as to give full play to the load-bearing function of the wall in the brick-concrete structure.

[0033] The following is combined with Figure 1 -4 Provide further details on this application.

[0034] Example 1

[0035] The embodiment of the present application discloses a brick-concrete wall structure. Figure 1 and Figure 2 The brick-concrete wall structure is fixed between the lower floor 8 and the upper floor 9. The brick-concrete wall structure includes a brick wall 1 and reinforcement columns 2. Along the length direction of the brick wall 1, the reinforcement columns 2 are arranged at intervals on the outside of the brick wall 1. The brick wall 1 is the original structure of the building. This application adds reinforcement columns 2 on the periphery of the brick wall 1 to improve the vertical load-bearing capacity and seismic performance of the wall in the brick-concrete structure. It is worth noting that the reinforcement columns 2 on different floors are located on the same vertical line to reduce the stress on the floor slab.

[0036] Reference Figure 1 The reinforcement column 2 includes a column 21 and a corbel 22. The column 21 and the corbel 22 are reinforced concrete structures and are integrally cast. The column 21 is fixedly connected to the brick wall 1, and the corbel 22 is fixedly connected to the upper floor slab 9. Along the width direction of the brick wall 1, the staff opened a receiving groove 11 on the side of the brick wall 1 near the upper floor slab 9 to accommodate the corbel 22.

[0037] Reference Figure 1 In this embodiment, a brick wall 1 is located within a building, with building spaces on both sides. Pairs of reinforcement columns 2 are provided on either side of the brick wall 1. These opposing reinforcement columns 2 are integrally cast. In this embodiment, a recess 11 is formed by cutting through the bricks on the side of the brick wall 1 near the upper floor slab 9.

[0038] Subsequently, workers set up steel cages on both sides of brick wall 1 and set up formwork; concrete is then poured into the formwork to form reinforcement column 2. Since the steel cages for column 21 and corbel 22 in reinforcement column 2 are conventional, this embodiment does not limit the form of the steel cages for reinforcement column 2 and does not include them in the drawings to improve the simplicity of the drawings.

[0039] Reference Figure 1The brick-concrete wall structure also includes tension bolts 3 and reinforcement bars 4. A plurality of tension bolts 3 are provided. Brick wall 1 has mounting holes 12 for the tension bolts 3. The tension bolts 3 are embedded in columns 21 on both sides of the brick wall 1. Several tension bolts 3 are spaced apart along the height of the columns 21. Reinforcement bars 4 are vertically arranged and embedded in the columns 21. They are tied and secured to the tension bolts 3.

[0040] When workers install the formwork for reinforcement column 2, tension bolts 3 secure the formwork, facilitating installation. After the concrete in the reinforcement column 2 solidifies, the tension bolts 3 secure the columns 2 on both sides of the brick wall 1, further strengthening the connection between the columns 2 and the brick wall 1. Using processed rebar to secure the tension bolts 3 further strengthens the tension between the two columns 2, further enhancing the integrity of the reinforced wall.

[0041] The implementation principle of a brick-concrete wall structure in the embodiment of the present application is:

[0042] Reference Figure 1 By opening an accommodating groove 11 on the side of the brick wall 1 close to the upper floor 9, the corbel 22 of the reinforcement column 2 is directly arranged between the brick wall 1 and the upper floor 9; so as to give full play to the synergistic effect of the reinforcement column 2 and the brick wall 1, so that the reinforcement column can share more vertical loads, thereby improving the bearing capacity and seismic performance of the wall, and improving the reinforcement effect of the wall in the brick-concrete structure.

[0043] The reinforcement columns 2 are arranged in pairs on both sides of the brick wall 1 to further improve the integrity of the reinforcement columns 2 and the brick wall 1, further improve the bearing capacity and earthquake resistance of the wall, and strengthen the reinforcement effect of the wall.

[0044] Example 2

[0045] The difference between this embodiment 2 and embodiment 1 is that:

[0046] Reference Figure 3 The brick-concrete wall structure also includes upper connecting bars 5 and lower connecting bars 6; each of the upper connecting bars 5 and lower connecting bars 6 is provided in plurality. One end of the upper connecting bar 5 is anchored to the upper floor slab 9, while the other end of the lower connecting bar 6 is embedded in the corbel 22. One end of the lower connecting bar 6 is anchored to the lower floor slab 8, while the other end is embedded in the column 21.

[0047] The implementation principle of a brick-concrete wall structure in the embodiment of the present application is:

[0048] By installing upper connecting steel bars 5 between the upper floor slab 9 and the corbels 22 of the reinforcing columns 2, the connection strength between the reinforcing columns 2 and the upper floor slab 9 is further improved; by installing lower connecting steel bars 6 between the lower floor slab 8 and the reinforcing columns 2, the connection strength between the lower floor slab 8 and the reinforcing columns 2 is further improved. In this way, the connection strength between the reinforcing columns 2 and the upper and lower floor slabs 9 and 8 is further improved, thereby improving the seismic performance of the brick-concrete structure.

[0049] Example 3

[0050] The difference between this embodiment 3 and embodiment 2 is that:

[0051] Reference Figure 4 , tensile strength fiber filaments 7 are further embedded in the reinforcement column 2, and the tensile strength fiber filaments 7 are dispersed in the reinforcement column 2. The tensile strength fiber filaments 7 can be made of materials such as steel fiber, polypropylene fiber and glass fiber; in this embodiment, the tensile strength fiber filaments 7 are made of polypropylene fiber.

[0052] Reference Figure 4 At the same time, the concrete poured into the reinforcement column 2 is slightly expansive concrete.

[0053] The implementation principle of a brick-concrete wall structure in the embodiment of the present application is:

[0054] By mixing the tensile strength fibers 7 into the concrete of the reinforcement column 2 , the tensile strength of the concrete in the reinforcement column 2 is increased, thereby improving the bearing capacity of the reinforcement column 2 .

[0055] The reinforcement column 2 is cast with micro-expansive concrete, and the micro-expansion effect of the micro-expansive concrete after solidification and hardening is utilized to make the reinforcement column 2 tightly connected with the upper floor 9 and the lower floor 8, so that the reinforcement column 2 can fully bear the vertical load and give full play to the load-bearing function of the wall in the brick-concrete structure.

[0056] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. 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.
