Description

Floor sealing connection structure

Technical Field

The utility model relates to a laminate flooring technical field, especially a floor sealing connection structure.

Background

The existing two adjacent composite floors are clamped through a locking structure, for example, U.S. Pat. No. 20190017277A1 discloses a locking structure, a first protrusion 7 protruding obliquely is arranged at the lower part of a first end of a floor block, a first gap 9 is formed between the first protrusion 7 and the floor block body, and a first slope 8 is arranged on one side of the first gap 9 facing the floor block body; the upper part of the second end of the floor board is provided with a second projection 10 which protrudes obliquely, a second gap 12 is formed between the second projection 10 and the floor board body, and the side of the second gap 12 facing the floor board body is provided with a second slope 11. When the lock catch is installed, two adjacent floor boards are required to be tightly matched, the installation requirement is high, and in order to prevent the two adjacent floor boards from moving in the vertical direction, a clamping structure is required to be arranged on the lock catch, such as a protruding part arranged at the upper right corner of the upward tongue 25, the right side of the complementary groove 32, the upper left corner of the downward tongue 28 and the like in fig. 3.

So need apply great strength when making the installation to realize the joint after overcoming the elasticity of the screens structure that corresponds, at the in-process of installation, if the too big screens structure fracture that then can lead to of applied strength gas, difficult dismantlement after the installation moreover leads to the screens structure to damage when dismantling easily, is difficult to recycle. In addition, although the gap of the splicing mode is small, a certain gap still exists, the waterproof performance is poor, and the splicing mode is not suitable for occasions with high requirements on the waterproof performance.

In order to overcome the above technical difficulties, it is proposed to coat a layer of wax on the locking structure to enhance the waterproof effect. The wax is used as a waterproof effect, namely, the wax is brushed, scraped, smeared and sprayed on the joint surfaces of the male buckle and the female buckle on site, and can be cured to form a coating film with waterproof capability. Depending on the variety of the waterproof coating, the following disadvantages still exist: (1) The environment temperature is greatly restricted, and particularly, the water-emulsion paint has higher requirements on the environment temperature in transportation, storage, stacking and construction operation; (2) The mechanical properties of the film are affected by the temperature of the forming environment. The reaction speed of the reaction curing type product is greatly influenced by the ambient temperature and humidity, the temperature is high, the humidity is low, the reaction speed is high, and the film forming quality is good. The water emulsion type or solvent type coating has high temperature, low humidity, fast volatilization of water or solvent, fast film forming speed and slow film forming speed at high temperature, and the water emulsion type material can not even form a film, but if the temperature in summer is too high, the surface of a film layer which is just coated is dehydrated too fast, and the wrinkling phenomenon can be generated, thereby affecting the film forming quality. Therefore, the construction should select proper environmental temperature and humidity conditions to ensure better film quality. (3) The film layer has the phenomenon of uneven thickness under the influence of the flatness of the base surface.

Based on the consideration of the above factors, the main objective of the present invention is to provide a floor sealing connection structure with strong water seepage prevention function.
