Description

Technical Field

[0001] This utility model relates to a joint sealing structure for wood grain fair-faced concrete joint strips, and relates to the field of building construction technology. Background Technology

[0002] Existing fair-faced concrete wood-grain walls often use 13mm thick and 135mm or 85mm wide wood-grain boards of varying lengths as inner formwork, and 18mm film-coated plywood as outer formwork. During construction, the formwork is constructed by aligning and splicing several formwork panels sequentially. Adhesive or sponge strips are filled into the joints between adjacent formwork panels to seal the joints. However, the sealing effect is limited, and phenomena such as grout leakage and grout dripping still occur during construction, seriously affecting the aesthetics of the fair-faced concrete wall. Cleaning the wall surface also increases the workload, which is very time-consuming and labor-intensive. In addition, the inner formwork panels are relatively small, resulting in too many joints. Therefore, it is necessary to improve the existing formwork structure and the sealing method of the joints. Utility Model Content

[0003] This utility model provides a joint sealing structure for wood grain exposed concrete joint strips to overcome the defect of poor sealing effect caused by too many joints in the existing technology of exposed wood grain concrete walls.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] This utility model discloses a joint sealing structure for wood grain fair-faced concrete joint strips, including fair-faced wood grain concrete joint strips. The fair-faced wood grain concrete joint strips are fastened to fair-faced formwork linings by air gun nails. Adjacent fair-faced formwork linings are connected by structural adhesive. The fair-faced wood grain concrete joint strip includes a wood grain fair-faced concrete template. The bottom surface of the wood grain fair-faced concrete template is provided with a sponge layer. Adhesive tape is provided below the sponge layer. The surface of the wood grain fair-faced concrete template is provided with edge sealing paint. Glass glue is located in the joint between two adjacent wood grain fair-faced concrete templates. Cast-in-place concrete is located in the middle of the two fair-faced wood grain concrete templates.

[0006] Furthermore, the seam is pre-cut into a bevel of 82° to 88°.

[0007] Furthermore, the outer surface of the clear water template liner is provided with tie rod holes, and the back is provided with several template secondary back ribs in the longitudinal direction and several template main back ribs in the transverse direction.

[0008] Furthermore, the secondary back ribs and the main back ribs of the template are arranged perpendicularly to each other.

[0009] Furthermore, the joint positions of the exposed wood grain concrete joint strip and the exposed formwork lining are staggered.

[0010] Furthermore, the spacing between the air gun nails is no greater than 100mm.

[0011] Furthermore, the structural adhesive is kept at least 1mm away from the inner side of the 15-18mm thick clear water template lining to prevent the structural adhesive from protruding under pressure, causing deformation of the joint strip, and thus affecting the jointing effect.

[0012] The beneficial effects achieved by this utility model are: by setting up a fair-faced concrete template lining, the expansion and deformation of the wood grain fair-faced concrete template splice joints during the pouring process is effectively reduced, and phenomena such as concrete leakage and grouting during the construction process are eliminated, ensuring the aesthetics of the fair-faced concrete wall and effectively guaranteeing construction efficiency and construction quality.
