Interlocking type plastic tile structure

Abstract

This invention relates to an interlocking type plastic tile structure in which the surface layer having a pattern thereon is coated with adhesive and then is combined with a PVC base layer adhered to the floor. A plurality of protruding tongues and a plurality of notches are respectively formed on two adjacent sides of the PVC base layer. With this structure, when two such plastic tiles are interlocked with respect to each other, the notches having adhesive layer are interlocked and adhered with the protruding tongues correspondingly so as to achieve assembly and good alignment. Besides, there is no need for providing release paper, therefore cost can be saved and assembly is very convenient.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]This invention relates to an interlocking type plastic tile structure, especially to an interlocking type plastic tile structure which is simple in assembling and precise in insertion and alignment by the formation of protruding tongues and notches capable of interlocking.[0003]2. Brief Description of the Prior Art[0004]The adhering structure of ordinary plastic tile, as shown in FIG. 5, substantially has printed layer between a main body (51) and a transparent leather (54), and the printed layer further includes a PVC leather material (52) and a printed pattern layer (53). The main body (51) is essentially formed by the mixing of PVC powder, calcium carbonate and toughening agent (DOP). The printed pattern layer (53) can be printed either on the bottom face of the transparent leather (54) or on the surface of the PVC leather material (52). Hot pressing is conducted on the main body (51), the PVC leather material (52), ...

AI Technical Summary

Benefits of technology

[0011]The main object of the interlocking type plastic tile structure of the present invention is to reduce the manufacturing cost of plastic tile, to enable good alignment of two plastic tiles, and to eliminate the requirement of coating adhesive on floor at construction site so as to make the construction easier and to achieve good appearance effect.

[0013]Essentially, the surface layer having pattern provided thereon is coated with adhesive and is combined with the PVC base layer in contact with floor, a plurality of protruding tongues and a plurality of notches being respectively formed on two adjacent sides of the PVC base layer. With this structure, when two such plastic tiles are interlocked with respect to each other, the notches having adhesive thereon are interlocked and adhered with the corresponding protruding tongues so as to finish assembly process and to achieve good alignment. Besides, there is no need to provide release paper, therefore cost can be saved and assembling can become very easy.

[0014]Moreover, the protruding tongues and the notches of the interlocking type plastic tile of the present invention are formed as dovetail shape. Alignment effect can be achieved in more stable manner by the mutual insertion and interlocking of the dovetail protruding tongues and the dovetail notches.

[0015]The upper surface of the interlocking type plastic tile structure of the present invention is combined with pattern which can be formed as stone material leather (marble leather), wood material leather (log leather), ceramic tile, cured resin coating, printed plastic baseboard, pure plastic tile, rubber tile, bamboo straw mat, wood tile, stone material tile etc., so as to enhance the aesthetic feeling and the selectivity of the plastic tile.

Problems solved by technology

However, the plastic tiles are apt to become oblique during adhesion by this method.

1. The protruding portions of the surface layer and the base layer are bigger in areas; this will cause bigger allowance of adhering two plastic tiles together so that there is bad alignment on plastic tiles. Eventually, the entire floor is not beautiful.

2. Release paper for protection purpose has to be provided on the protruding portion of the base layer having bigger area when manufacturing the plastic tile. Thus, manufacturing cost is high in this case.
