Description

Technical Field

[0001] This application relates to the technical field of joint sealing, and in particular to a wall panel sealing device. Background Art

[0002] In the construction of the prefabricated building PC structure system, after the components are installed, a joint will be formed between the bottom and the floor slab. Before the internal embedded grouting sleeve and the bottom reserved steel bars are connected by high-pressure grouting, the joint needs to be effectively sealed.

[0003] When pouring the concrete of the cast-in-place layer, leakage of grout will occur at the joint. If the joint is not properly treated, the forming quality of the beam and slab soffit after pouring will be extremely poor, and the leakage of grout will pollute the formwork and working surface under the beam and slab.

[0004] Currently, in the construction of prefabricated frame structure projects, the common method for dealing with the beam and slab joints is to use materials such as foaming agents to seal the joints, but the sealing effect of the foaming agent is weak, and leakage of grout often occurs. Utility Model Content

[0006] A wall panel sealing device provided by this application adopts the following technical solutions:

A flexible sealing layer is fixed on the outer side, and a plurality of strengthening members are fixed on the inner side. Both ends of the strengthening member are respectively connected to the horizontal plate and the vertical plate.

[0008] By adopting the above technical solutions, during sealing, the sealing layer blocks and seals the joint. The sealing layer is made of a flexible material and can adapt to local unevenness of the floor slab surface or component surface through slight elastic deformation, preventing leakage of grout during high-pressure grouting. The sealing plate is a rigid member, not easily deformed, which can improve the strength of the sealing device, can withstand greater pressure, further reduce the leakage of grout, and improve the sealing effect.

[0009] Preferably, an outwardly protruding connecting strip is fixed on the outer side, and a connecting groove connected to the connecting strip is formed on one side of the sealing layer facing the outer side.

[0010] By adopting the above technical solutions, the sealing layer is connected to the sealing plate through the connecting groove and the connecting strip, increasing the contact area between the two and improving the connection strength.

[0011] Preferably, a plurality of inclined strengthening rods are fixed on the connecting strip. One end of the strengthening rod is fixedly connected to the connecting strip, and the other end points to the sealing plate.

[0012] By adopting the above technical solution, the reinforcing rod further increases the contact area between the sealing layer and the plugging plate, improving the connection strength.

[0013] Preferably, a limiting groove is formed on the inner side, and the reinforcing member is inserted into the limiting groove.

[0014] By adopting the above technical solution, the limiting groove limits and fixes the reinforcing member, facilitating subsequent welding and fixing.

[0015] Preferably, a chamfer inclined outward is provided at the opening of the limiting groove.

[0016] By adopting the above technical solution, the chamfer facilitates the insertion of the reinforcing member.

[0017] Preferably, limiting grooves are formed on both side walls of the inner side and are communicated with each other.

[0018] By adopting the above technical solution, the reinforcing member can be inserted into the limiting groove from two directions, facilitating installation.

[0028] The following further describes the present application in detail with reference to all the attached drawings. Embodiment 1

[0029] The embodiment of the present application discloses a wall panel plugging device. Refer to Figure 1 , which includes a plugging plate 1 and a sealing layer 2. The plugging plate 1 is formed by fixedly connecting a horizontal plate 11 and a vertical plate 12. One end of the horizontal plate 11 is fixedly connected to one end of the vertical plate 12 to form a plugging plate 1 with an L-shaped cross-section. The plugging plate 1 is a rigid member and can be made of a rigid material. The sealing layer 2 is made of a flexible material, such as rubber and other materials.

[0030] Refer to Figure 1 , the plugging plate 1 includes an inner side 14 and an outer side 13. When installing the plugging plate 1, the outer side 13 faces the joint, and the inner side 14 faces away from the joint. The sealing layer 2 is fixedly connected to the outer side 13. A reinforcing member 3 is fixed to the inner side 14. A plurality of reinforcing members 3 are provided along the length direction of the plugging plate 1, thereby improving the overall structural strength of the plugging plate 1. The cross-section of the reinforcing member 3 is triangular to improve the structural strength of the reinforcing member 3.

[0031] Refer to Figure 1 , an installation groove 17 is formed on the horizontal plate 11. An installation strip 5 with stripes is fixed at the installation groove 17. Installation holes with stripes are formed on the installation strip 5, and expansion bolts 6 are arranged in the installation holes. The horizontal plate 11 is connected to the floor slab or component through the expansion bolts 6, further improving the stability of the sealing plate during the grouting process and preventing slurry leakage.

[0032] The implementation principle of the wall panel plugging device in the embodiment of the present application is as follows: after the component hoisting is completed, the plugging plate 1 is installed at the joint position between the bottom of the component and the floor slab, the position of the plugging plate 1 is adjusted, and the expansion bolts 6 on the plugging plate 1 are aligned with the position of the embedded sleeve on the floor slab. The installation and reinforcement are completed by screwing the expansion bolts 6 with the sleeves on the floor slab. Subsequently, high-pressure grouting is carried out inside the wall. After the grouting material meets the design requirements, the expansion bolts 6 are loosened to remove the overall device, and the plugging plate 1 is cleaned and maintained for the next turnover use. Embodiment 2

[0033] The difference between Embodiment 2 and Embodiment 1 lies in the different structures of the plugging plate 1: Refer to Figure 2 , a plurality of connecting strips 4 protruding outward for connecting with the sealing layer 2 are fixed to the outer side 13. A plurality of inclined reinforcing rods 41 are fixed to the connecting strips 4. One end of the reinforcing rod 41 is fixedly connected to the connecting strip 4, and the other end points to the plugging plate 1. A connecting groove 21 connected to the connecting strip 4 is formed on one side of the sealing layer 2 facing the outer side 13. The sealing layer 2 is connected to the plugging plate 1 through the connecting groove 21 and the connecting strip 4, increasing the contact area between the two, improving the connection strength, and making it difficult for the two to separate.

[0034] Reference Figure 2 , limiting grooves 15 are formed on both side walls of the inner side 14 and communicate with each other. Chamfers 16 inclined outward are provided at the openings of the limiting grooves 15. The reinforcing member 3 is inserted into the limiting groove 15. Both sides of the reinforcing member 3 are embedded in the limiting groove 15. The two ends of the reinforcing member 3 are respectively connected to the cross plate 11 and the vertical plate 12. The limiting groove 15 pre-positions the reinforcing member 3 to facilitate subsequent welding and fixing.
