Description

Technical Field

[0001] The utility model relates to the technical field of existing building repair construction, and in particular to a new sealing structure and system which are convenient for construction. Background Art

[0002] At present, the building structure has undergone significant changes, and prefabricated buildings have become the main structural form of many buildings. In the prefabricated building structure, leakage of board seams has become the most common problem among the facade defects of this type of building. Solving the sealing and anti-leakage of board seams has become the focus of prefabricated building repair.

[0003] The existing prefabricated building board seams are mostly sealed by modified silicone sealants; high-strength non-shrinkage sealing mortar (rigid connection) is used for filling, and the surface is sealed and waterproofed with weather-resistant sealants and polymer waterproof coatings.

[0004] For board joints sealed directly with modified silicone sealant, the sealing and anti-leakage effects are greatly affected by the material durability and construction quality of the sealant. Generally, the sealant effect will be greatly reduced in about 5 years, resulting in leakage. The practice of using high-strength non-shrinkage sealing mortar (rigid connection) for filling and then sealing and waterproofing the surface with weather-resistant sealant and polymer waterproof coating will cause the sealing mortar to crack or even fall off due to the influence of building temperature changes, settlement deformation and other forces, and the surface sealant and waterproof coating will crack, resulting in leakage at the board joints.

[0005] The existing repair methods are mostly to re-pour sealant on site, but pouring sealant on site has high requirements for construction technology. If the operation is improper, the sealing strip will not adhere firmly, affecting the sealing effect. Another method is to use a sealing strip with a cavity for filling, and then increase the cross-sectional area of ​​the sealing strip by inflating the cavity, and use the extrusion force to better bond the sealing strip to the gap, thereby improving the construction quality, but the construction process is more cumbersome.

[0006] At present, no effective solution has been proposed for the problems of inconvenient construction and poor adhesion of on-site glue injection sealing strips in related technologies. Utility Model Content

The first blocking element 111 and the second blocking element 112 are filled between the seams of the prefabricated building panels through the elasticity of their own materials, and at the same time, an extrusion force is generated to make the second blocking element 112 and the fixing element 181 bonded more tightly.

[0154] The advantage of the utility model is that by arranging the first cavity unit and the second cavity unit inside the sealing unit, the cross-sectional width of the sealing unit can be changed. At the same time, the first constraint unit and the second constraint unit are respectively arranged inside the first cavity unit and the second cavity unit and connected with a compression unit. The cross-sectional width of the sealing unit can be adjusted more conveniently, which solves the problems of inconvenient on-site construction of glue injection sealing strips and poor adhesion.

[0155] Example 2

[0156] This embodiment is a supplementary embodiment of Embodiment 1.

[0157] like Figure 8 As shown, the novel sealing structure 100 further includes a reinforcing unit 190 . The reinforcing unit 190 is disposed between the blocking unit 110 and the fixing unit 180 to increase the connection force between the blocking unit 110 and the fixing unit 180 .

[0158] Specifically, the reinforcing unit 190 is disposed between the first blocking element 111 , the second blocking element 112 and the fixing element 181 .

[0159] In some of the embodiments, the reinforcement unit 190 is integrally formed with the first blocking element 111 / the second blocking element 112 .

[0160] The size of the reinforcing unit 190 matches the size of the first blocking element 111 / the second blocking element 112. Generally, the axial size of the reinforcing unit 190 is equal to the axial size of the first blocking element 111 / the second blocking element 112.

[0161] In some of the embodiments, the cross section of the reinforcement unit 190 is sawtooth-shaped.

[0162] In some of the embodiments, the reinforcement unit 190 includes but is not limited to tooth-like protrusions.

[0163] The advantage of the utility model is that the plugging unit is connected more tightly to the fixing unit by arranging the reinforcement unit, so that the plugging unit is not easy to fall off, thereby reducing the frequency of later maintenance.

[0164] Example 3

[0165] This embodiment relates to a novel sealing system of the utility model.

[0166] A new sealing system that is convenient for construction and is used for repairing joints of assembled panels in buildings, comprising the new sealing structure and the auxiliary installation structure as described in Examples 1 and 2. The auxiliary installation structure is detachably connected to the positioning unit of the new sealing structure, so as to keep the blocking unit of the new sealing structure in a vertical state during installation.

[0167] In some of the embodiments, the auxiliary mounting structure is a metal support rod.

[0168] The advantage of the utility model is that the auxiliary installation structure is used to achieve a detachable connection with the positioning unit, so that the first sealing unit and the second sealing unit can be kept in a straight state when the new sealing structure is installed, thereby improving the construction quality and avoiding the shear force between the new sealing structure and the prefabricated panels on both sides, thereby reducing the risk of breakage.

[0169] The above description is only a preferred embodiment of the present invention, and does not limit the implementation mode and protection scope of the present invention. For those skilled in the art, it should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
