Description

Technical Field

[0001] This utility model relates to the field of waterproofing technology for splice seams, and in particular to a waterproof sealing structure for splice seams of plastic flooring. Background Technology

[0002] In modern architecture and interior decoration, vinyl flooring has become an increasingly popular choice for homes and commercial spaces due to its excellent wear resistance, stain resistance, and ease of cleaning. However, the treatment of the seams during the installation of vinyl flooring is one of the key factors affecting its performance and lifespan. A waterproof sealing structure for the seams, through proper design and material selection, effectively prevents moisture from seeping into the seams, reducing warping, deformation, and damage caused by moisture, thereby extending the floor's lifespan and maintaining its aesthetic appeal.

[0003] Existing waterproof sealing methods for PVC flooring seams primarily employ adhesives, sealants, or specialized waterproof strips. Common techniques involve applying sealant or using waterproof strips to the seams to prevent moisture from seeping into the flooring gaps. During installation, workers typically apply pressure to the seams to ensure a tight bond between the sealant and the flooring. While these traditional methods achieve a degree of waterproofing, they often suffer from uneven adhesive application and inconsistent pressure, resulting in poor sealant distribution and leaving some areas at risk of leakage. Therefore, a new waterproof sealing method for PVC flooring seams is proposed to address these issues. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a waterproof sealing structure for the joints of plastic flooring, which aims to improve the problems of uneven glue application and inconsistent pressure in the prior art, resulting in poor glue distribution.

[0005] To achieve the above objectives, the present invention provides a waterproof sealing structure for the joints of plastic flooring, comprising:

[0006] Optionally, the plastic sheet has an extension on one side and a pressing part on the other side;

[0007] The arc-shaped groove is formed on both sides of the upper surface of the plastic sheet;

[0008] Positioning strips, located at the top of the extension, are used to align adjacent plastic sheets;

[0009] The positioning groove is located at the bottom of the crimping part and is used to fit with the positioning strip.

[0010] Optionally, the extension is located on the lower side of one end face of the plastic sheet, and the pressing part is located on the upper side of the other end face of the plastic sheet.

[0011] Optionally, the outline of the arc-shaped groove is semi-circular arc, and adjacent arc-shaped grooves are spliced ​​together to form an adhesive coating groove.

[0012] Optionally, when adjacent extensions and crimping portions are in contact, the positioning strip is embedded inside the positioning groove.

[0013] Optionally, when two plastic sheets are pressed together, adjacent extensions and pressing parts are fitted together, and the thickness of the spliced ​​extensions and pressing parts is consistent with the thickness of the plastic sheets.

[0014] The above-mentioned technical solutions in the waterproof sealing structure for the joints of plastic flooring provided in this embodiment of the utility model have at least one of the following technical effects:

[0015] In this invention, when laying the floor, the extension of one plastic sheet is aligned with the pressing part of the adjacent plastic sheet and pressed down, so that the positioning strip fits into the positioning groove, thus preventing displacement. Then, waterproof adhesive is applied into the arc-shaped groove and pressure is applied to make the extension and pressing part fit tightly together. The combined arc-shaped groove ensures that the adhesive is evenly distributed. Through the cooperation between the above structures, splicing displacement is effectively avoided, enhancing the accuracy of installation. Secondly, it helps to apply adhesive evenly, prevents water penetration, and improves waterproof performance. Attached Figure Description

Then, apply an appropriate amount of waterproof glue to the arc groove 4 between the splices. Next, the construction worker applies appropriate pressure to make the extension 2 and the pressing part 3 fit tightly together. The adjacent arc grooves 4 also merge due to splicing. After the glue dries and cures, the laying of the two plastic sheets 1 is completed.
