Description

Technical Field

[0001] This invention relates to the field of prefabricated building construction technology, and in particular to a prefabricated building sealing device and construction method. Background Technology

[0002] Most prefabricated shear wall structures use the sleeve grouting method for connection. After the components are installed, the bottom of the components needs to be sealed to form a closed space to ensure the smooth implementation of sleeve grouting. Currently, the sealing method is basically manual grouting and plastering. This construction method not only makes it difficult to guarantee the thickness of the bottom seal and results in uneven quality, but also has low construction efficiency, which is not in line with the development direction of building industrialization. Summary of the Invention

[0003] The main objective of this invention is to provide a prefabricated building sealing device and construction method, which aims to solve existing technical problems.

[0004] To achieve the above objectives, the present invention provides a prefabricated building sealing device, comprising: a clamp and a tube, wherein the clamp has a through hole communicating with the tube;

[0005] The clamp includes a first plate, a second plate, and a third plate connected in sequence. The connection angle between the first plate and the second plate is 90°. The first plate, the second plate, and the third plate form a material-containing space. One end of the material-containing space is open. The material-containing space is used to contain the injected slurry. During the movement of the clamp, the slurry stays in the installation seam in a specified shape.

[0006] Furthermore, the third plate includes a front plate and a rear plate, with both ends of the rear plate connected to the front plate and the second plate respectively. The connection angle between the rear plate and the second plate is 0-90°, and the front plate is arranged parallel to the first plate.

[0007] Furthermore, the third plate includes a front plate and a rear plate. The two ends of the rear plate are connected to the front plate and the second plate, respectively. The connection angle between the rear plate and the second plate is 0-90°. Both the front plate and the rear plate are inclined in a direction away from the first plate, with an inclination angle of 0-90°.

[0008] Furthermore, the connection angle between the rear plate and the second plate is 60°.

[0009] Furthermore, brushes are evenly distributed on the upper and lower edges of the second and third plates, as well as the lower edge of the first plate.

[0010] Furthermore, the bottoms of the first, second, and third plates are flush, the tops of the second and third plates are flush, and the top of the first plate is higher than the top of the second and third plates.

[0011] Furthermore, the first plate is characterized by having a baffle that rotates around its end, the baffle rotating toward and connecting to the third plate to enclose the material-containing space, and the baffle rotating toward and coplanar with the first plate to extend the length of the first plate.

[0012] The baffle is connected to the first plate or the third plate respectively by a magnetic structure, and the outer surface of the baffle is provided with protrusions.

[0013] Furthermore, the front section of the pipe is inclined and the pipe opening faces the second plate, and the angle between the extension line of the rear section of the pipe and the plane of the first plate is 45°.

[0014] A method for sealing a prefabricated building, using the prefabricated building sealing device described above, includes the following steps:

[0015] S1: After the two prefabricated parts are connected during assembly, an installation seam is formed at the connection point. The grouting equipment is connected to the pipe body through a hose, and then the clamp is horizontally placed into the installation seam to complete the preparation work.

[0016] S2: Grout is injected into the material space of the clamp through the grouting equipment. After the material space is completely filled, the clamp is moved forward along the installation joint. During this process, the first plate in the clamp is kept in contact with the surface of the precast part, and grout is continuously injected. The grout stays in the installation joint in a specified shape.

[0017] S3: Inject the grout according to the above steps. The grout forms a rectangular closed loop in the installation joint, sealing the four sides of the installation joint and completing the sealing operation around the installation joint. After the grout has completely solidified, subsequent construction operations can be carried out.

[0018] Furthermore, in S2, when the grouting operation begins on each side of the installation joint, the clamp is first placed at one end of the installation joint and the two ends are kept aligned. The baffle is rotated to align with the third plate, sealing the material space. Grout is then injected into it. After the current material space is completely filled, the baffle is rotated back to its original position, keeping it on the same plane as the first plate. The clamp is then moved forward along the installation joint and grouting continues until the front end of the clamp moves to the other end of the installation joint and remains aligned, completing the grouting and sealing operation on that side.

[0019] The beneficial effects of this invention are reflected in:

[0020] This invention features a simple structure, is reusable, and easy to use. It changes the traditional methods of grouting and filling by following the grouting process, reducing the difficulty of operation and producing high-quality concrete after injection. This effectively improves construction efficiency and speed, enhances sealing quality, and reduces costs. Attached Figure Description

[0032] Please see Figure 1 The present invention provides a prefabricated building sealing device, comprising: a clamp 10 and a tube 20, wherein the clamp 10 has a through hole communicating with the tube 20;

[0033] The clamp 10 includes a first plate 10a, a second plate 10b, and a third plate 10c connected in sequence. The connection angle between the first plate 10a and the second plate 10b is 90°. The first plate 10a, the second plate 10b, and the third plate 10c constitute a material holding space. One end of the material holding space is open. The material holding space is used to hold the injected slurry. During the movement of the clamp 10, the slurry stays in the installation seam in a specified shape.

[0034] Connect the grouting equipment to the pipe body 20 and place the clamp 10 into the installation joint. As the grouting work proceeds, move the clamp 10 forward along the installation joint in sync, so that the grout stays in the installation joint in a specified shape, thereby quickly achieving the sealing operation.

[0035] The use of this device changes the traditional methods of grouting and filling. By following the grouting process, the difficulty of operation is reduced, and the quality of the injected concrete is good. This can effectively improve construction efficiency and speed, enhance the sealing quality, and reduce costs.

[0036] In one embodiment, please refer to Figure 2 The third plate 10c includes a front plate 10c2 and a rear plate 10c1. The two ends of the rear plate 10c1 are connected to the front plate 10c2 and the second plate 10b, respectively. The connection angle between the rear plate 10c1 and the second plate 10b is 0-90°. The front plate 10c2 is arranged parallel to the first plate 10a.

[0037] This design creates a funnel-shaped structure where the material holding space is larger at the front and smaller at the back. After the slurry is injected, it first fills the local space facing the second plate 10b within the material holding space. Then, the slurry overflows to the open end of the material holding space. Since the volume of the front space is larger than that of the rear space, as the clamp 10 moves forward along the installation seam, the slurry in the front space transitions to the rear space. During this transition, the slurry is compressed, making the slurry that has been formed and detached from the clamp 10 more compact and less prone to deformation, thus maintaining the sealing quality of the slurry in the installation seam.

[0038] Preferably, the connection angle between the rear plate 10c1 and the second plate 10b can be 60°. This connection angle ensures that the thickness of the slurry output remains within a reasonable range, while allowing the slurry to be subjected to appropriate extrusion pressure during the output process, so that the compactness of the slurry after output meets the requirements and will not easily cause deformation.

[0039] In one embodiment, please refer to Figure 3 The third plate 10c is tilted in a direction away from the first plate 10a, with an tilt angle of 0-90°.

[0040] With this configuration, since the third plate 10c is tilted away from the first plate 10a, after the slurry is injected into the material storage space, as the clamp 10 moves, it is blocked by the third plate 10c to maintain its specified shape during output. At the same time, it is also subjected to the vertical force exerted by the third plate 10c on the slurry, so that the slurry can be subjected to downward extrusion force during the output process. This makes the slurry that is formed and separated from the clamp 10 more compacted and less prone to deformation, thereby maintaining the sealing quality of the slurry in the installation joint.

[0041] Preferably, the tilt angle of the third plate can be 60°, because at this tilt angle, the slurry can be subjected to appropriate downward pressure during the output process, while ensuring that the height of the output slurry fills the installation joint and adapts to the actual width of the installation joint.

[0042] In one embodiment, please refer to Figure 4 Brushes 30 are evenly distributed on the upper and lower edges of the second plate 10b and the third plate 10c, as well as the lower edge of the first plate 10a.

[0043] Specifically, the length of the brush 30 is set to 5mm. This setting can accommodate the uneven height difference of the bottom gap of the precast component. The brush 30 is a flexible material that can deform according to the height and has a good bond with the upper and lower surfaces. At the same time, it also has the function of preventing the sealing material from overflowing.

[0044] In one embodiment, please refer to Figure 4The bottoms of the first plate 10a, the second plate 10b, and the third plate 10c are flush, the tops of the second plate 10b and the third plate 10c are flush, and the top of the first plate 10a is higher than the top of the second plate 10b and the third plate 10c.

[0045] With this configuration, after the clamp 10 is placed into the installation seam, the top of the first plate is higher than the top of the second plate 10b and the third plate 10c, allowing the protruding plate to press against the surface of the precast component. This makes it easier for the operator to control the movement of the clamp 10. They only need to push it forward along the installation seam without having to shift their attention to keep the clamp 10 flush with the surface of the precast component. This ensures that the slurry output is flush with the surface of the precast component, reducing the difficulty of operation and improving the quality of sealing.

[0046] In one embodiment, please refer to Figure 3 The first plate 10a is provided with a baffle 40 that rotates around its end. The baffle 40 rotates toward the third plate 10c and connects with it to close the material storage space. The baffle 40 rotates toward the first plate 10a and is coplanar with it to extend the length of the first plate 10a.

[0047] This configuration allows the baffle 40 to be rotated and aligned with the third plate 10c at the start of the sealing construction, thus sealing the open material-containing space. This enables efficient construction at the beginning of the installation joint, preventing the slurry from overflowing at the open end after injection. After the sealing operation at the beginning of the installation joint is completed, rotating the baffle 40 to be coplanar with the first plate 10a extends the limiting effect of the first plate 10a on the output slurry, allowing the slurry to maintain its shape and blockage for a longer period. This is beneficial for improving the molding strength of the slurry after it is fully exposed and avoids the problem of easy deformation after the slurry detaches from the clamp 10.

[0048] The baffle 40 is connected to the first plate 10a or the third plate 10c via a magnetic attraction structure, and the outer surface of the baffle 40 is provided with a protrusion 41. Two magnetic blocks (not shown in the figure) are embedded in the baffle 40 to facilitate quick connection with the first plate 10a or the third plate 10c after rotation. Specifically, the magnetic block connected to the first plate 10a is located near the rotating end of the baffle 40, and the magnetic block connected to the third plate 10c is located at an appropriate position on the inner surface of the baffle 40.

[0049] In one embodiment, please refer to Figure 5 The front section of the tube body 20 is inclined and the tube opening faces the second plate 10b. The angle between the extension line of the rear section of the tube body 20 and the plane of the first plate 10a is 45°.

[0050] This configuration ensures that during slurry injection, the space near the second plate 10b is filled first, and then the slurry flows to the rear space, maintaining the continuity of slurry output and avoiding discontinuity. At the same time, the direction of slurry injection is opposite to the direction of slurry output, which reduces the pressure of the injected slurry on the output slurry and avoids deformation caused by excessive pressure on the output slurry.

[0051] A method for sealing the prefabricated building's perimeter, employing the prefabricated building perimeter sealing device described above, includes the following steps, please refer to [link / reference]. Figure 6 ,

[0052] S1: After the two prefabricated parts are connected during assembly, an installation seam is formed at the connection point. The grouting equipment is connected to the pipe body 20 through a hose, and then the clamp 10 is horizontally placed into the installation seam to complete the preparation work.

[0053] S2: Grout is injected into the material space of clamp 10 through grouting equipment. After the material space is completely filled, clamp 10 is moved forward along the installation joint. During this process, the first plate 10a in clamp 10 is kept in contact with the surface of the precast part, and grout is continuously injected. The grout stays in the installation joint in a specified shape.

[0054] S3: Inject the grout according to the above steps. The grout forms a rectangular closed loop in the installation joint, sealing the four sides of the installation joint and completing the sealing operation around the installation joint. After the grout has completely solidified, subsequent construction operations can be carried out.

[0055] By using the above construction method, the traditional methods of grouting and filling are changed. By following the grouting method, the difficulty of operation is reduced, and the quality of the injected concrete is good. This can effectively improve construction efficiency and speed, improve the sealing quality, and reduce costs.

[0056] In one embodiment, in step S1, when grouting begins on each side of the installation joint, the clamp 10 is first placed at one end of the installation joint and aligned with it. The baffle 40 is then rotated to align with the third plate 10c, sealing the material space. Grout is then injected into the space until it is completely filled. The baffle 40 is then rotated back to its original position, keeping it on the same plane as the first plate 10a. The clamp 10 is then moved forward along the installation joint, and grouting continues until the front end of the clamp 10 moves to the other end of the installation joint and remains aligned, completing the grouting and sealing operation on that side. This operation avoids the problem of grout overflowing at the initial end of the installation joint, preventing the joint from failing to form a closed structure and requiring subsequent manual grouting. This improves construction efficiency and sealing quality.

[0057] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
