[0028] The principles and features of the present application will be described below in conjunction with the accompanying drawings, and the examples are only used to explain the present application and are not intended to limit the scope of the present application.
[0029] As Figures 1-6 shown, the shear wall and structural wall pull seam construction structure of the present embodiment comprises a shear wall 1, a structural wall 2 and an extruded plate 3, a pull seam interval is reserved between the shear wall 1 and the structural wall 2, the extruded plate 3 is adaptively clamped in the pull seam interval, and the extruded plate 3 is connected and fixed with the embedded steel bars in the shear wall 1 and / or the embedded steel bars in the structural wall 2. Figure 1 In the middle, a window 6 position is reserved on the structural wall 2.
[0030] As Figure 2 shown, the extruded plate 3 of the present embodiment is connected and fixed with the embedded steel bars in the shear wall 1 and / or the embedded steel bars in the structural wall 2.
[0031] A preferred scheme of the present embodiment is that the extruded plate 3 and the embedded steel bars in the shear wall 1 and / or the embedded steel bars in the structural wall 2 are fixed by wire binding.
[0032] Specifically, the thickness of the extruded plate 3 is 30-50 mm. The extruded plate is reliably fixed on the vertical steel bars of the embedded steel bars in the shear wall by wire binding or other fixing measures. After the concrete pouring is completed, the structure pull seam outside is sealed by silicone sealant to prevent leakage.
[0033] As Figure 2 shown, the width of the extruded plate 3 of the present embodiment is less than the thickness of the structural wall 2, one end of the extruded plate 3 is flush with the outdoor side of the structural wall 2, and the other end of the extruded plate 3 does not exceed the indoor side of the structural wall 2. The construction effect is avoided from being affected by the exposed extruded plate.
[0034] As Figure 3 and Figure 4 shown, the top of the structural wall 2 of the present embodiment is provided with a metal plate 4, and the metal plate 4 is welded and fixed with the top embedded steel bars of the structural wall 2. By providing the metal plate, the construction joint soft connection between the structural wall and the structural beam 5 can be realized.
[0035] One specific scheme of the embodiment is that the metal plate 4 is a thin steel plate with a thickness of 2-4 mm, preferably 3 mm. The horizontal structural gap between the top structure wall and the structural beam is welded with a 3 mm thin steel plate on the top of the structure wall reinforcement after the structure wall reinforcement is bound, and then the beam reinforcement on the top of the structure wall is bound. The concrete between the structure wall and the structural beam is connected by the steel plate.
[0036] As shown in Figure 1 The metal plate 4 of the embodiment is provided with multiple metal plates 4 arranged in sequence along the length direction of the top of the structure wall 2. By providing multiple metal plates, the stability of the connection between the structure wall and the structural beam 5 can be ensured, and the relative displacement of the two in the horizontal direction is allowed, so as to avoid the cracking of the wall caused by temperature changes, uneven settlement and other factors, and improve the durability and integrity of the building exterior wall.
[0037] One specific scheme of the embodiment is that the spacing between two adjacent metal plates 4 is 100-150 mm.
[0038] As shown in Figure 3 and Figure 4 The metal plate 4 of the embodiment is arranged in an inner high and outer low manner, one end of the metal plate 4 close to the indoor side of the structure wall 2 is bent upward to form a vertically arranged first bent plate 41, and the other end of the metal plate 4 close to the outdoor side 22 of the structure wall 2 is bent downward to form a second bent plate 42; the end of the first bent plate 41 is provided with a gap with the indoor side 21 of the structure wall 2, and the end of the second bent plate 42 is flush with the outdoor side 22 of the structure wall 2. By arranging the metal plate in an inclined and bent manner, it can closely fit the connecting surface of the structure wall and the structural beam. The thin steel plate is bent according to the design requirements, with an inner high and outer low structure, so that it can closely fit the connecting surface of the structure wall and the beam. A 100 mm diameter concrete pouring and vibrating hole is reserved on the steel plate or the steel plate is installed in sections (100-150 mm gap is reserved between sections for concrete pouring and vibrating).
[0039] The vertical connecting part of the shear wall and the structural wall is positioned according to the design requirement interval, and the installation position of the extruded plate is determined. The cut extruded plate is embedded in the position of the elastic line in sequence, and the extruded plate is tightly attached to the shear wall and the structural wall. The joint gap between adjacent extruded plates should be controlled within 3mm, and the sealant is used for sealing treatment to prevent rainwater leakage. During the installation process of the extruded plate, the steel bars are cut according to the design requirements to ensure that the shear wall and the structural wall can be relatively independent deformation in the vertical direction, and cracks caused by stress concentration due to the connection of the steel bars are avoided. The extruded plate is fixed on the shear wall and the structural wall steel bars by tying the wire to ensure that the extruded plate will not be displaced during the construction process. After the steel bars of the structural wall are tied, a 3mm thin steel plate is welded on the top of the structural wall steel bars, and then the beam steel bars on the top of the structural wall are tied. The thin steel plate is bent according to the design requirements, and the inner part is high and the outer part is low, so that it can be tightly attached to the connecting surface of the structural wall and the beam. The vertical pull seam and the top soft connection part are comprehensively checked to check whether the installation of the extruded plate and the steel plate is firm, whether the filling of the sealant and the flexible sealing material is full and dense, and whether there are cracks, holes and other defects. The cut-off position of the steel bars is checked to ensure that the structure of the shear wall and the structural wall is clear in stress, and there is no structural safety hazard caused by construction errors. The structure pull seam part of the completed construction is subjected to water test to test its waterproof performance. If leakage and other problems are found, timely repair treatment is carried out until the waterproof requirement is met.
[0040] The shear wall and the structural wall pull seam construction structure of the embodiment realizes the soft connection between the structural wall and the shear wall by setting the extruded plate between the shear wall and the structural wall, so as to solve the problem that cracks may be generated between the structural wall and the shear wall due to different stiffness and inconsistent deformation. By using the extruded plate as the vertical pull seam material, the heat and sound insulation performance of the outer wall is effectively improved, and the flexible property of the extruded plate can adapt to certain structural deformation and reduce the possibility of crack generation. The soft connection design of the top thin steel plate can ensure the stability of the connection between the structural wall and the beam, and allow the relative displacement of the two in the horizontal direction, so as to avoid wall cracking caused by temperature change, uneven settlement and other factors, and improve the durability and integrity of the building outer wall. The construction method steps are clear and easy to operate, the materials are easy to obtain, which is conducive to improving the construction efficiency and construction quality, reducing the construction cost, and having good economic benefit and social benefit.
