Abstract

A sliding connection structure of a flooring panel using a connector is provided to restrict a gap between the flooring panels, and to prevent dimensional deformation, bending or distortion due to humidity or temperature change by efficiently connecting and installing the flooring panels with the connector. Two panels(10c,20c) include wood boards(11c,21c) and surface layers(12,22). Grooves(14c,23c) are formed at a side and a lower part of the wood board to insert a connector(30c). The groove is processed easily, and breakage is restricted by opening a lower part of the panel. A flooring panel is constructed simply by pushing and fitting the panels to the connector after fixing the connector in a floor. The connector comprises a thick plate body(31c), a couple of upper rail parts(32c,33c) vertically protruded and symmetrically formed at both ends of the body, and side rail parts(34c,35c) horizontally protruded at both sides of the body.

The present invention relates to a system for effectively connecting a building floor panel, and preferably to a connection system of a floor layer panel using a wood-based board and a surface layer using a synthetic resin raw material.

As a product widely used as a flooring material of the prior art, in order to prevent dimensional deformation, based on a water-resistant plywood in which one or more natural wood veneers are incorporated, the natural veneer is integrated with an adhesive, and then urethane acrylic There is a plywood ondol floor coated with a surface treatment agent of latex material.

This conventional plywood ondol flooring is attached to the bottom floor by epoxy adhesive, which is rather cumbersome, and during installation, the adhesive between the tongue and the grooves is squeezed up, which must be removed by wiping or drying with a wet mop. You can't walk around or put furniture on the floor panels for hours. In addition, there is a disadvantage that the floor must be broken when moving to another location by disassembling the floor.

In addition to the plywood ondol floor, there is a reinforced flooring product including a printing layer impregnated with melamine resin and a surface treatment layer of melamine material based on MDF (Medium Density Fiberboard) or HDF (High Density Fiberboard) layer.

These conventional reinforced flooring materials are mutually coupled to each other by a tongue and groove coupling (Tongue and Groove coupling), the flooring is mostly adhesive to the tongue and grooves. This flooring is a problem that the flooring can be separated from each other by shrinkage expansion of the inner substrate layer.

Several different types of couplings have been proposed to remedy this drawback. However, this approach has begun to reveal each of the disadvantages, and look at these problems depending on the type of the form.

The coupling types are classified into three types: snap type, click type, and mechanical coupling type. The snap type connection system has the inconvenience of using a tool and tongue and groove several times. When combined, there is a drawback that can be cracked by affecting the coupling structure of the groove.

In addition, the connection system which can be fastened by mechanical interlock type can be combined only by rotation, and it is weaker than the click type, and when the construction floor is not smooth, there is a gap between floor panels. There is a possibility to occur.

As disclosed in the Republic of Korea Patent No. 430315, the connection system that can be fastened in a click (click) type has the advantage of being able to combine both rotation and horizontally and the best coupling force ever seen form. However, since the coupling portion of the tongue and the groove is formed in a single piece with the core of the bottom panel, the tongue and the groove protruding by the impact during transportation or construction may be easily damaged. In addition, when the tongue and the groove is combined several times, the splitting effect is frequently affected by the lower lip of the coupling structure of the groove.

The present invention has been made to solve the problems of the conventional floorboard panel described above, the object of the present invention is to prevent the breakage and cracking of the lower lip of the tongue or groove protruded by the impact during transportation and construction It is to provide the connection structure of the panel.

Another object of the present invention can be connected regardless of the shape of the pentagon, hexagons, etc. as well as the rectangular form used in the conventional floor floor panel, and the connection structure of the floor panel that can be constructed by constructing a variety of patterns (pattern) To provide.

Another object of the present invention is to provide a connection structure of the floor panel having a structure that can maintain excellent bonding force irrespective of the smoothness of the construction floor and does not occur curling (curling).

Still another object of the present invention is to provide a connection structure of a floor panel that can be easily installed by anyone without processing and expertise.

The present invention, in order to achieve the above object, in the connection structure of the adjacent floor panel, using a connector consisting of a body and at least one rail portion protruding from the body, but the side of the panel corresponding to the shape of the connector The groove is formed, and provides a connection structure of the floor panel, characterized in that the connector is inserted in the form of a slide in the coupling groove formed by the coupling between the panel.

According to the present invention, grooves are formed on side and edges of two adjacent panels so that the two bottom panels can be connected to each other, and then a connector can be pushed in a slide form to effectively connect the grooves. It is characterized by.

In addition, grooves are formed on both sides and edges without tongue, so there is little risk of breakage, easy processing, and no curling occurs while ensuring excellent bonding force. The advantage is that you can realize DIY (Do It Yourself) that can be easily installed by anyone.

According to a preferred embodiment of the present invention, as shown in Figure 5, the groove is formed in the adjacent side and bottom surface of the panel side portion, the connector is two or more rail portions protruding vertically from the top of the body And two or more rail portions protruding horizontally from both sides of the body.

According to this embodiment, since the lower surface is opened, the grooving is easier and the risk of breakage is less. In particular, when the connector is fixed to the floor during construction, the panel can be inserted into the connector to be easily installed. .

According to another embodiment of the present invention, the groove may be formed only toward the side of the panel side.

According to the first embodiment of the present invention, as shown in Fig. 3, the connector includes four or more rail portions protruding vertically from the top and bottom of the body. In this embodiment, both sides (tongue parts) of the body serve to remove the shankdong, ie, step difference, of the panel, and the rail portion serves to prevent the lateral movement of the panel.

According to the second embodiment of the present invention, as shown in FIG. 4, the connector includes four or more rail parts protruding in the vertical direction from both ends of the upper and lower parts of the body. In this embodiment, the rails are formed at both ends of the body to facilitate processing.

According to the fourth embodiment of the present invention, as shown in FIG. 6, the connector includes four or more rail parts protruding obliquely from each upper and lower ends of the body. In this embodiment, the rail portion is inclined at both ends of the body, so that it is easier to process and can be easily inserted while receiving less force.
