Abstract
Description
Technical Field
[0002] The utility model relates to the technical field of double-sided laminated shear wall construction, in particular to a slurry leakage prevention structure at the root of a double-sided laminated shear wall.
Background Art
[0004] In the field of building construction, shear wall structures are widely used due to their good seismic performance and space utilization rate. Among them, the precast double-sided laminated shear wall is a common construction method, in which concrete is poured between two precast walls to form an integral shear wall structure.
[0005] In the construction of double-sided laminated shear walls, the prevention of slurry leakage at the root of the wall has always been a challenge. Traditional slurry leakage prevention methods usually use mortar for plugging. However, this approach has the following defects:
[0006] Difficult to guarantee construction quality: The quality of mortar plugging is affected by various factors, such as the construction level of workers, the proportion of mortar, and the construction environment. If the construction quality is poor, it is easy to cause gaps between the mortar and the precast wall, resulting in slurry leakage problems.
[0007] Easy to leak slurry during later pouring: Even if the construction quality of mortar plugging is good, during the later concrete pouring, due to the limited adhesion between the mortar and the precast wall, it is still possible for the mortar to loosen or fall off due to the impact or vibration of the concrete, resulting in slurry leakage problems.
[0008] Difficult to repair: Once a slurry leakage problem occurs, it is very difficult to repair. On the one hand, it is necessary to clean and chisel the already poured concrete, which will increase the construction cost and duration; on the other hand, the construction quality after repair is also difficult to guarantee, which may become a potential quality hazard.

Detailed Embodiments
[0032] In order to make the technical problems, technical solutions and beneficial effects solved by this application clearer, the following further details this application in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not used to limit this application.
[0033] This embodiment provides a leak-proof slurry structure at the root of a double-sided composite shear wall, which is used to avoid the problem of potential leak slurry at the root of the wall during the later concrete pouring caused by using traditional mortar to plug the wall foot during the construction of the double-sided composite shear wall. Please refer to Figures 1 to 2 A leak-proof slurry structure at the root of a double-sided composite shear wall includes a set of relatively arranged precast walls 1. A receiving cavity 2 for pouring concrete is formed between the two precast walls 1. A leak-proof component 3 for preventing concrete from leaking from the receiving cavity 2 is provided at the root of the wall along the length direction of the precast wall 1.
[0034] In this embodiment, by setting the leak-proof component 3 at the root of the wall, it should be noted that the leak-proof component 3 can be set at the inner root of the precast wall 1 or at the outer root of the wall. At the same time, the leak-proof component 3 is consistent with the whole length of the precast wall 1, which can effectively solve the problem of leak slurry during concrete pouring and improve the construction quality.
[0035] Further, as a preferred implementation manner rather than a limitation of this solution, the leak-proof component 3 includes plugging members 31 respectively arranged along the outer wall roots of the two lengths of the precast wall body 1. The plugging members 31 are connected with supporting templates 32 for fixing them. The supporting templates 32 are also in fit contact with the precast wall body 1 for reinforcement and support.
[0036] In order to fix the plugging member 31, in this embodiment, the plugging member 31 is connected with a supporting template 32 for fixing it. The supporting template 32 is in fit contact with the precast wall body 1, which not only provides additional supporting force to the wall body, but also plays a role in restricting the movement of the plugging member 31 to ensure that the plugging member 31 remains stable during the process of pouring concrete, thereby improving the leak-proof effect.
[0037] Specifically, the plugging member 31 can have an L-shaped cross section to adapt to the shape and size of the precast wall body 1 and provide a good sealing effect. The supporting template 32 can be made of rigid materials such as metal or plastic, preferably aluminum formwork, which is more fitting to the wall surface while providing sufficient supporting force.
[0038] Further, as a preferred implementation manner rather than a limitation of this solution, a sealing gasket 33 that can be in close fit with the ground is also provided at the bottom of the plugging member 31. The thickness of the sealing gasket 33 is 2 - 5 mm, preferably 5 mm.
[0039] In this embodiment, the sealing gasket 33 can be made of an elastic material, such as a rubber gasket or a silicone gasket. By providing the sealing gasket 33 at the bottom of the plugging member 31, the contact area with the ground can be increased, and an additional sealing effect can be provided, thereby more effectively preventing the concrete from leaking out of the accommodating cavity 2.
[0040] To optimize the performance of the sealing gasket 33, the thickness of the sealing gasket 33 is 2 - 5 mm, preferably 5 mm. A sealing gasket with a thickness range in the interval of 2 - 5 mm can, on the premise of ensuring the sealing effect, avoid the too thick sealing gasket 33 increasing the construction difficulty and cost. And the preferred thickness of 5 mm can provide a good sealing effect in most cases and take into account the construction convenience and cost - effectiveness.
[0041] Further, as a preferred implementation manner rather than a limitation of this solution, the plugging member 31 is an angle steel that fits the internal corner of the root of the precast wall body 1. One right - angled surface of the angle steel is in fit contact with the precast wall body 1, the other right - angled surface presses the sealing gasket 33, and the upper end of this right - angled surface abuts against the supporting template 32.
[0042] In this embodiment, in order to improve the strength and stability of the plugging member 31, the plugging member 31 is an angle steel that fits the internal corner at the root of the precast wall 1, which has good strength and stiffness and can provide sufficient supporting force to ensure the leak-proof effect.
[0043] Specifically, one right-angle surface of the angle steel is attached to the precast wall 1 to increase the contact area and improve the connection stability. The other right-angle surface presses the sealing gasket 33. Through the rigid action of the angle steel, the sealing gasket 33 is tightly pressed on the ground to provide a good sealing effect. At the same time, the upper end of this right-angle surface abuts against the support formwork 32. Through the supporting action of the support formwork 32, the stability of the angle steel is further improved, preventing it from shifting or deforming during the concrete pouring process, so that the concrete has a better forming appearance.
[0044] Furthermore, as a preferred implementation manner rather than a limitation of this solution, a reserved notch 11 is provided at the root of the two precast walls 1 along the length direction to accommodate the vertical right-angle surface of the angle steel, facilitating the use of the stiffness of the angle steel to ensure that the bottom concrete in-situ casting area is not deformed under the influence of the concrete lateral pressure, thereby achieving a better concrete appearance. The reserved notch 11 is consistent with the length of the precast wall 1.
[0045] In this embodiment, in order to better utilize the stiffness characteristics of the angle steel and ensure that the bottom concrete in-situ casting area is not deformed under the influence of the concrete lateral pressure, thereby achieving a better concrete appearance, a reserved notch 11 is provided at the root of the two precast walls 1 along the length direction to accommodate the vertical right-angle surface of the angle steel.
[0046] Specifically, the reserved notch 11 is consistent with the length of the precast wall 1, that is, it corresponds to the entire root of the precast wall 1. In this way, during the construction process, the vertical right-angle surface of the angle steel can be completely placed in the reserved notch 11, making it closely fit with the precast wall 1, so as to better play the supporting and fixing roles of the angle steel. At the same time, due to the large stiffness of the angle steel, it can effectively resist the influence of the concrete lateral pressure and prevent the bottom concrete in-situ casting area from deforming, thereby ensuring the appearance quality of the concrete.
[0047] Furthermore, as a preferred implementation manner rather than a limitation of this solution, diagonal bracing assemblies 4 for strengthening the support formwork 32 are respectively provided on the outer sides of the two precast walls 1.
[0048] In order to further improve the stability of the support formwork 32 and prevent it from shifting or deforming during the concrete pouring process, diagonal bracing assemblies 4 for strengthening the support formwork 32 are respectively provided on the outer sides of the two precast walls 1 in this embodiment.
[0049] By setting the diagonal bracing component 4, the support points of the support formwork 32 can be increased, improving its overall stability. During the concrete pouring process, due to the support of the diagonal bracing component 4, the support formwork 32 is not prone to displacement or deformation, thus ensuring the leak prevention effect and construction quality.
[0050] Furthermore, as a preferred implementation manner of this solution rather than a limitation, the diagonal bracing component 4 includes a diagonal bracing base 41 fixed to the ground. The diagonal bracing base 41 is hinged with a first diagonal bracing rod 42. One end of the first diagonal bracing rod 42 away from the diagonal bracing base 41 is hinged with a first fixing member 43 that abuts against the lower part of the support formwork 32. The diagonal bracing base 41 is also hinged with a second diagonal bracing rod 44. One end of the second diagonal bracing rod 44 away from the diagonal bracing base 41 is hinged with a second fixing member 45 that abuts against the upper part of the support formwork 32.
[0051] In this embodiment, the diagonal bracing base 41 is hinged with a first diagonal bracing rod 42. One end of the first diagonal bracing rod 42 away from the diagonal bracing base 41 is hinged with a first fixing member 43 that abuts against the lower part of the support formwork 32. Through the cooperation of the first diagonal bracing rod 42 and the first fixing member 43, the lower part of the support formwork 32 can be strengthened, improving its stability during the concrete pouring process.
[0052] In order to further improve the stability of the support formwork 32, in this embodiment, the diagonal bracing base 41 is also hinged with a second diagonal bracing rod 44. One end of the second diagonal bracing rod 44 away from the diagonal bracing base 41 is hinged with a second fixing member 45 that abuts against the upper part of the support formwork 32. It should be added that in some other embodiments, when the need for strengthening the side of the support formwork 32 is not high, the components of the diagonal bracing component 4 can also be connected by means such as bolt connection, snap connection, and welding.
[0053] To sum up, through the cooperation of the second diagonal bracing rod 44 and the second fixing member 45, the upper part of the support formwork 32 can be strengthened, improving its stability during the concrete pouring process. On the basis of the cooperation of the first diagonal bracing rod 42 and the first fixing member 43, a comprehensive overall strengthening of the support formwork 32 can be achieved, further improving its anti-deformation ability. Therefore, the leak prevention effect of the entire double-sided laminated shear wall root leak prevention structure is improved at the root.
[0054] Even further, as a preferred implementation manner of this solution rather than a limitation, a cushion block 12 abutting against the ground is provided at the bottom of the precast wall 1. Through the adjustment of the gasket 12, it can be ensured that the precast wall panel can be accurately positioned during installation, avoiding wall inclination or misalignment caused by uneven ground or installation errors. At the same time, it helps to reduce the gap between the lower part of the precast wall and the ground, improving the sealing and stability of the overall structure and avoiding leakage of concrete during pouring.
[0055] Working principle of the utility model:
[0056] This embodiment provides a slurry leakage prevention structure at the root of a double-sided laminated shear wall, aiming to solve the problem that traditional mortar plugging at the wall foot is prone to slurry leakage during later concrete pouring.
[0057] The core of this slurry leakage prevention structure lies in the leakage prevention component 3, which is arranged at the root of the precast wall 1 and is consistent with the length direction of the precast wall. The main function of the leakage prevention component is to prevent concrete from leaking from the accommodation cavity 2.
[0058] The leakage prevention component includes a plugging piece 31 and a supporting formwork 32. The plugging piece is arranged at the outer root of the precast wall in the length direction to directly prevent concrete leakage. The plugging piece is preferably an angle steel with an L-shaped cross-section to adapt to the shape of the precast wall and provide a good sealing effect.
[0059] The supporting formwork is in fit and abutment with the precast wall to fix the plugging piece and provide additional supporting force. The supporting formwork is preferably made of a rigid material such as an aluminum formwork to ensure stability during concrete pouring.
[0060] To further enhance the sealing effect, a sealing gasket 33 is provided at the bottom of the plugging piece. The sealing gasket is made of an elastic material such as a rubber gasket or a silicone gasket, with a thickness of 2 - 5 mm, preferably 5 mm. The sealing gasket is in close fit with the ground to increase the contact area and prevent concrete leakage.
[0061] A reserved notch 11 is provided at the root of the precast wall for placing the vertical right-angle surface of the angle steel. The reserved notch is consistent with the length of the precast wall to ensure that the angle steel can be completely placed therein, providing better support and fixation.
[0062] To enhance the stability of the supporting formwork, a diagonal bracing component 4 is provided on the outer side of the precast wall. The diagonal bracing component includes a diagonal bracing base 41, a first diagonal bracing rod 42, a first fixing piece 43, a second diagonal bracing rod 44, and a second fixing piece 45. These components reinforce the upper and lower parts of the supporting formwork through hinge or bolt connection methods, etc., to improve its anti-deformation ability.
[0063] A cushion block 12 is provided at the bottom of the precast wall to adjust the installation position of the precast wall panel, ensure its accurate alignment, reduce the gap with the ground, and improve the sealing and stability of the overall structure.
[0064] In summary, this slurry leakage prevention structure at the root of the double-sided laminated shear wall effectively solves the problem of slurry leakage during concrete pouring through the coordinated action of the leakage prevention component, the reserved notch, the diagonal bracing component, and the cushion block, improving the construction quality and the visual effect of the concrete.
[0065] The above are the implementation manners provided in combination with specific contents, and it is not determined that the specific implementation of this application is only limited to these descriptions. Any approximation or similarity to the method structure of this application, or any technical deduction or replacement made under the premise of the concept of this application, shall be regarded as the protection scope of this application.
