Description

Technical Field

[0001] This application relates to the technical field of walls, and in particular to a cast-in-place exterior wall structure. Background Art

[0002] Except for shear walls, exterior walls are generally masonry brick walls. The traditional exterior wall construction process is to use the brick wall as a secondary structure. After the shear wall is cast, the brick wall is then masoned.

[0003] In this process, the secondary masonry of the brick wall occupies the construction space of the exterior wall, affecting the processes such as plastering and painting of the exterior wall. Moreover, it requires secondary construction itself, lengthening the overall working hours and affecting the implementation progress of the overall project. Summary of the Invention

[0004] In order to speed up the construction progress of the project, this application provides a cast-in-place exterior wall structure.

[0005] A cast-in-place exterior wall structure provided by this application adopts the following technical solutions:

[0006] A cast-in-place exterior wall structure includes a wall body. The wall body includes a steel reinforcement cage and concrete filling and wrapping the steel reinforcement cage. Vertical joint plates are fixed on the left and right sides of the steel reinforcement cage, and horizontal joint plates are fixed at the upper and lower ends of the steel reinforcement cage. A number of PVC core pipes are vertically fixed inside the steel reinforcement cage.

[0007] By adopting the above technical solutions, the steel reinforcement cage in the exterior wall body is fixedly connected to the steel reinforcement cage on the shear wall, and vertical joint plates and horizontal joint plates are respectively arranged on both sides and around the steel reinforcement cage of the exterior wall body to separate the exterior wall and the shear wall. When casting the shear wall, the exterior wall and the shear wall can be integrally cast and formed at the same time, thus eliminating the inconvenience of secondary construction, optimizing the construction process, and accelerating the construction progress.

[0008] Preferably, the vertical joint plates and the horizontal joint plates are made of plastic thin plates.

[0009] By adopting the above technical solutions, the plastic thin plates have a certain toughness, so that the wall body of the exterior wall is flexibly connected to the shear wall, reducing the risk of brittle failure of the structure during an earthquake and effectively improving the impact resistance of the shear wall at the same time.

[0010] Preferably, the outer walls of the vertical joint plates and the horizontal joint plates are provided with connecting pieces extending outwards.

[0011] By adopting the above technical solutions, the connecting pieces increase the contact area between the vertical joint plates and the horizontal joint plates and the concrete, thereby increasing the connection strength between the two.

[0012] Preferably, the ends of the connecting pieces are bent to form connecting hooks.

[0013] By adopting the above technical solution, the connecting hook further increases the contact area between the connecting plate and the concrete, making the vertical and horizontal crack plates bond tightly with the concrete.

[0014] Preferably, the vertical and horizontal crack plates are hollow, and there are several reinforcing plates arranged in the inner cavity.

[0015] By adopting the above technical solution, the vertical and horizontal crack plates are lighter in weight, and the reinforcing plates can ensure the structural strength of the vertical and horizontal crack plates. At the same time, it can reduce the overall weight of the wall, making the optimized wall have a weight similar to that of the original masonry wall, avoiding changes in wall loads and ensuring the safety of the structural system.

[0016] Preferably, a pipe cap is hermetically connected to the end of the PVC core pipe.

[0017] By adopting the above technical solution, it effectively avoids slurry leakage in the pipe and realizes weight reduction of the PVC core pipe.

[0018] Preferably, several limiting rings fixedly connected to the steel reinforcement cage are arranged on the outer wall of the PVC core pipe, and the PVC core pipe is arranged inside the limiting rings.

[0019] By adopting the above technical solution, several limiting rings fixed in the steel reinforcement cage limit the PVC core pipe, preventing the PVC core pipe from shifting during the concrete pouring process.

[0020] Preferably, several fixing rings are circumferentially arranged on the outer wall of the pipe cap, a tension wire is connected to the fixing rings, the other end of the tension wire is wound around the steel reinforcement cage, and the tension wire is in a taut state.

[0021] By adopting the above technical solution, the tension wire applies a pulling force to the pipe cap, pressing the pipe cap tightly on the PVC core pipe. At the same time, the tension wire applies pressure to the PVC core pipe from all angles around, improving the stability of the PVC core pipe and preventing the PVC core pipe from shifting during the concrete pouring process.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. The outer wall and the shear wall can be integrally cast and formed at the same time, thus eliminating the inconvenience of secondary construction, optimizing the construction process, accelerating the construction progress, avoiding the influence of outer wall masonry on other processes, and saving a large amount of labor and material costs;

[0024] 2. Using the PVC core pipe as the core cavity of the cast-in-place wall reduces the overall weight of the cast-in-place lightweight structure, which is almost the same as the weight of the originally designed masonry outer wall, avoiding an increase in building self-weight that does not meet the design requirements;

[0025] 3. The structural tension joint process is adopted, using plastic thin plates as the tension joint materials to isolate the cast-in-place exterior wall from the load-bearing shear wall, enabling flexible connection between the two. This reduces the risk of brittle structural failure during earthquakes and effectively improves the impact resistance of the shear wall. Description of the Drawings

[0031] The following further elaborates on this application in conjunction with all the drawings. First Embodiment

Referring to Figures 1 to 2 , it includes a wall body, which is composed of a steel reinforcement cage 1, concrete 2, a vertical tension joint plate 3, a horizontal tension joint plate 4, and a PVC core pipe 5.

[0033] Referring to Figures 1 to 2 , there are two vertical tension joint plates 3 respectively located on the left and right sides of the steel reinforcement cage 1, and two horizontal tension joint plates 4 respectively located on the upper and lower sides of the steel reinforcement cage 1. A number of connection holes for the main reinforcement on the steel reinforcement cage 1 to pass through are provided on the vertical tension joint plate 3 and the horizontal tension joint plate 4. The vertical tension joint plate 3 and the horizontal tension joint plate 4 are made of plastic thin plates and have a certain deformation ability. The steel reinforcement cage 1 of the exterior wall is fixedly connected to the steel reinforcement cage of the external shear wall 13, and the wall body is separated from the external shear wall 13 by the vertical tension joint plate 3 and the horizontal tension joint plate 4. During pouring, the external shear wall 13 and the wall body of the exterior wall are cast integrally at the same time, eliminating the inconvenience of subsequent secondary construction.

[0034] Referring to Figures 1 to 2 , moreover, the exterior wall is flexibly connected to the external shear wall 13 through the vertical tension joint plate 3 and the horizontal tension joint plate 4, reducing the risk of brittle structural failure during earthquakes and effectively improving the impact resistance of the shear wall.

[0035] Referring to Figures 1 to 2, the vertical split plate 3 and the horizontal split plate 4 are hollow, and there are several reinforcing sheets 8 in the inner cavity. While achieving weight reduction, the structural strength of the vertical split plate 3 and the horizontal split plate 4 themselves can be ensured, preventing cracking during the pouring of the concrete 2.

[0036] Refer to Figures 1 to 2 , the outer walls of the vertical split plate 3 and the horizontal split plate 4 are provided with connecting pieces 6 extending outwards, and the ends of the connecting pieces 6 are bent to form connecting hooks 7. The connecting pieces 6 and the connecting hooks 7 increase the contact area between the vertical split plate 3 and the horizontal split plate 4 and the concrete 2, so that the vertical split plate 3 and the horizontal split plate 4 are bonded tightly with the concrete 2.

[0037] Refer to Figures 1 to 2 , the PVC core pipe 5 is vertically connected inside the steel reinforcement cage 1 and is located between two vertical split plates 3, and the two ends of the PVC core pipe 5 do not exceed the horizontal split plate 4. The end of the PVC core pipe 5 is hermetically connected with a pipe cap 9 to prevent the concrete 2 from entering the PVC core pipe 5.

[0038] Refer to Figures 1 to 2 , a number of limiting rings 10 are fixed on the steel reinforcement cage 1, the limiting rings 10 are arranged vertically in columns, and there are several columns arranged. The PVC core pipe 5 is vertically inserted into the limiting rings 10 arranged in columns. The limiting rings 10 limit the PVC core pipe 5 to prevent the PVC core pipe 5 from shifting during the pouring of the concrete 2.

[0039] The implementation principle of the cast-in-place exterior wall structure in the embodiment of the present application is as follows: The operator makes the steel reinforcement cage 1 with anti-cracking steel bars. After the end of the PVC core pipe 5 is sealed by the pipe cap 9, the PVC core pipe 5 is limited by the limiting rings 10 and the PVC is connected to the steel reinforcement cage 1. A number of connecting holes are opened on the vertical split plate 3 and the horizontal split plate 4, and the vertical split plate 3 and the horizontal split plate 4 are installed around the steel reinforcement cage 1 through the connecting holes. Then the formwork is installed, and after the formwork installation is completed, the concrete 2 is poured, and after the pouring is completed, the formwork is removed. Embodiment Two

[0040] The difference between Embodiment Two and Embodiment One lies in the different structures of the pipe cap 9. Refer to Figure 3 , a number of fixing rings 11 are circumferentially arranged on the outer wall of the pipe cap 9, a tension wire 12 is connected to the fixing rings 11, the other end of the tension wire 12 is wound around the steel reinforcement cage 1, and the tension wire 12 is in a taut state. The tension wire 12 applies a pulling force to the pipe cap 9 to press the pipe cap 9 tightly on the PVC core pipe 5. At the same time, the tension wire 12 applies a pressure to the PVC core pipe 5 from all angles around, improving the stability of the PVC core pipe 5 and preventing the PVC core pipe 5 from shifting during the pouring of the concrete 2.
