Description

mosaic floor

The invention is related to the floor structure, in particular to a wood-plastic polystyrene (PS) mosaic floor with a special connection structure.

Commonly used wooden mosaic floor 10 is caused by thermal expansion and contraction due to climate change or moisture. The wooden floor is pushed and deformed after expansion, causing the surface of the floor to swell or even break. Therefore, when the floor is assembled, the distance between the floor A sufficiently wide gap needs to be reserved between them. As shown in Figure 1, it is a floor commonly used in the industry. The conventional mosaic floor 10 includes two boards 11 arranged in parallel. A parallel corresponding groove 12, a plurality of fixed parts 13 that meet in a predetermined space are connected between each of the plates. In each of the grooves 12, each of the fixing parts 13 is fixed on a beam frame (not shown in the figure), and the two plates 11 are connected so that the two are separated from each other by a vertical gap 15 from top to bottom. As far as this conventional mosaic floor 10 is concerned, the bottom of the gap 15 can be clearly seen directly from the outside, which is not very attractive in appearance, and if any foreign matter falls into the gap 15, it will directly fall on the floor and be difficult to take out.

In order to solve the foregoing problems, in the wood covering floor for outdoor and indoor disclosed in the U.S. No. US7546717 patent case, the two opposite end faces of the adjacent wood coverings each have a variety of end faces with different structural designs for Prevent sundries from falling into the gaps between the adjacent wood coverings and avoid looking directly at the internal structure of the gaps. However, this type of structure is quite complicated, and there are many sharp corners at the joints of the floor boards, which are very fragile. It is easy to be broken during transportation, and if it is broken, it will lose the original protective effect of preventing small things from falling off; for this reason, if the total thickness of the floor itself is increased to reinforce the sharp corners and easy cracks, it will cost a lot of production. cost, making such products expensive and uncompetitive.

In view of the lack of the above-mentioned conventional technology, one of the objects of the present invention is to provide a wood-plastic polystyrene (PS) mosaic floor with a special connection structure, which aims to effectively connect two adjacent ones with a simple and low-cost structure. When the floors are spliced together and fixed on a beam frame, it prevents sundries from falling into the gap between the two adjacent floors, and at the same time solves the deformation problem of the wooden floor due to temperature changes.

In order to achieve one of the above objects, the mosaic floor of the present invention includes a first board body, a second board body and a connector, the first board body has a first end surface, and the first end surface is provided with a lower convex portion and a first concave groove, the lower convex part extends horizontally from the bottom edge of the first end surface, the first concave groove is adjacent to the upper part of the lower convex part, and the second plate is spaced from the first plate The second plate body has a second end surface opposite to the first end surface, and the second end surface is provided with an upper convex portion and a second concave groove, and the upper convex portion is horizontally formed from the top edge of the second end surface. Extending out, the second concave groove is adjacent to the lower portion of the upper convex portion, the upper convex portion is vertically opposite to the lower convex portion, the connecting piece is arranged between the first plate body and the second plate body, the The connector has a base and an arm vertically connected to the base, a first slot which engages with the lower protrusion is formed between one side of the arm and the base, and the other of the arm The side protrudes into the second groove.

In the present invention, through the simple structural design of the upper convex part and the lower convex part arranged oppositely, the sundries falling into the gap all fall on the lower convex part, so that these sundries can be taken out conveniently, and can also avoid falling into the gap. Look directly at the bottom of the gap from the outside.

Preferably, the first plate body further includes a first side and a second side opposite to each other, and the first side and the second side are respectively vertically connected to the two sides of the first end surface, and the second side is provided with a non-slip surface.

Preferably, the second plate body further includes an opposite third side and a fourth side, the two third sides and the fourth side are vertically connected to the two sides of the second end face respectively, and the fourth side is provided with a non-slip surface.

Preferably, the anti-slip surface includes a plurality of grooves.

Preferably, the base of the connector has a through hole passing through the base.

Preferably, the first groove and the second groove are arranged horizontally.

In order to achieve the above-mentioned another purpose, the material of the first plate body and the second plate body is a thermoplastic elastic soft body.

Preferably, a thermoplastic elastic soft rubber layer is processed by injection molding on the second side.

Preferably, the fourth side is injection-molded with a thermoplastic elastic soft rubber layer.

The present invention utilizes these highly elastic and weather-resistant raw materials to make the boards or connectors by wrapping and combining or separately molding, so as to solve the problem of thermal expansion and contraction, thereby increasing the service life of the mosaic floor.

The detailed structure, features, assembly or usage of a mosaic floor provided by the present invention will be described in the subsequent detailed description of the implementation. However, those with ordinary knowledge in the field of the present invention should understand that the detailed description and the specific embodiments enumerated for implementing the present invention are only for illustrating the present invention, and are not intended to limit the scope of the patent application of the present invention.
