Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a dry floating floor that is placed on a cushioning material such as glass wool mats laid on a subfloor surface such as a concrete slab to form a floor surface. The present invention relates to floor panels and their construction methods.

(Prior Art) Floating floor structures have conventionally been used to reduce floor impact noise. This floating floor has the first
As shown in Figure 2, a so-called dry floating floor structure in which a floor surface is formed by placing floor panel materials c in parallel in a horizontal direction via a cushioning material layer b laid on a subfloor a; There is a wet floating floor structure in which a floor surface is formed by pouring concrete onto the buffer material.

Conventionally, floor panel materials used in the former type of dry floating floor include panel materials such as plywood and wood cement boards, but these panel materials tend to bend and deform due to impact force. For this,
In order to prevent the bending vibration of this panel material from being transmitted to the flooring through the cushioning material, a joist material d or a large tensioner is placed on the cushioning material layer b as shown in Fig. 12, and the floor panel It is constructed by fixing material c with nails e, etc.

(Problem to be Solved by the Invention) However, when constructing a dry floating floor as described above, each joist is installed at a predetermined interval on a soft cushioning material such as glass wool mat, and after assembling the base, the floor panels are assembled. Since the material is fixed to the joist material, the joist material may not be stable on soft cushioning material.
When the floor panel material was installed, the joist material vibrated, sank, or tilted diagonally, making it difficult to securely secure it to the surface floor panel material, resulting in poor workability.

In addition, in the conventional method described above, since the joists are placed continuously around the lower surface of the floor panel material, if the floor panel material repeatedly bends and deforms due to floor impact force, the screws that fix the floor panel material to the joist material There was a problem that the effectiveness of the screws etc. deteriorated or screws etc. came off, making it impossible to maintain a strong bond between the two.

The present invention has been made in view of the above conventional drawbacks, and has excellent rigidity as a floor panel material used for dry floating floors as described above, and can firmly connect mutual floor panel materials without using joists or the like. Moreover, it is an object of the present invention to provide a floor panel and a method for constructing the same, which allow easy connection of the panel materials.

(Means for Solving the Problems) In order to achieve the above object, the means taken by the present invention is to make the panel material as the base of the floor panel lightweight and high in bending rigidity, and to bend the panel material as a base material of the floor panel by the impact force of the floor. In order to prevent deformation, it is constructed by a hollow panel formed by connecting the front and back materials with a piece of wood, or by a hollow panel integrally formed by extrusion molding.

Furthermore, in order to connect the panel materials without requiring joists or the like, a leg member is integrally provided on at least one end of the lower surface of the panel material and protrudes outward by an appropriate dimension from the side surface of the panel material. establish. In addition, at the other end of the panel material, holes or notches are made in a portion of the panel surface material located directly above the panel back material that will be overlapped with the protruding portions of the leg members when the panel materials are arranged side by side, and fixed with screws. It has an opening for working.

In addition, as a construction method for the floor panels, the floor panels are arranged side by side with the protrusions of the leg members aligned with the openings of the adjacent floor panels, and the adjacent floor panels are connected through the openings. By fastening the back material and the leg members with screws, the floor panels are joined together to form an integrated floor surface.

(Function) With the above configuration, in the present invention, when the floor panels are installed side by side, the opening of the panel surface material is By tightly connecting the back material of adjacent floor panels and the leg members through screws, it is possible to firmly connect each floor panel to each other on the lower surface side thereof. From this, unlike the conventional method of installing floor panels by arranging joists, there is no need to specially construct receiving materials such as joists, and the workability is good, and the leg members are integrated with the panel materials. Since these leg members are used to connect floor panels together, there is no sinking or tilting of the receiving material when screwing, and the lower surface of the panel and the upper surface of the leg members are in close contact with each other to provide a strong fixation. Is possible.

In addition, since an opening communicating with the hollow part of the panel material is provided in advance in the surface material of the other end of the floor panel to be combined with the leg member at a position corresponding to the leg member, the overlapping of the floor panels is prevented. Even if the position of the leg member in the section cannot be seen, the floor panels can be fastened together simply by screwing through the opening.

Furthermore, since the panel material is formed from a hollow panel and the back material is overlapped and bonded to the leg member, even if the surface material of the hollow panel is thickened to increase rigidity, the surface material Can be joined using only the backing material, regardless of thickness. In addition, since it is joined only with the back material, the bending rigidity of the hollow panel is improved, and there is no deformation due to tightening of the surface material, and there is no possibility of screws coming off due to floor impact force, making it strong. It is possible to maintain a strong bond.

It should be noted that the leg members do not need to be kept protruding all the time, but can be rotatably attached to the bottom surface of the panel material.
It may be made to protrude from the side during construction.
In this way, the leg members will not be damaged during packaging or transport handling, and the handling properties will be good.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

FIG. 1 shows a floor panel A according to an embodiment of the present invention, which is installed in parallel in the horizontal direction on a subfloor surface via a cushioning material in a dry floating floor. In the figure, 1 is a panel material made of a hollow panel as a floor panel base, and the panel material 1 is made of front and back materials 1a and 1b made of plywood, particle board, slate, etc., with appropriate intervals between them. A plurality of plywood or metal beams 1c, 1c...
It is a combination of...

Incidentally, the beam material may be one in which the protrusions are integrally formed by cutting the front and back materials. Further, the slats may be in the form of blocks that are intermittently dispersed between the front and back surfaces.

A plurality of plate-shaped leg members 2, 2, . . . projecting outward from the side surface of the panel material 1 by an appropriate dimension are integrally provided on the lower surfaces of two adjacent side ends of the panel material 1. On the other hand, at the other two side ends of the panel material 1, a panel back material 1 is overlapped with the protrusion 2a of the leg member 2 when the panel materials 1 are arranged side by side.
An appropriately shaped opening 3 for screw fastening is provided at a portion of the panel surface material 1a located directly above b.

Here, as shown in FIG. 2, the leg member 2 is provided at one end of the panel material 1 in the form of a long plate, with only a part thereof protruding from the side surface of the panel material 1, and most of the leg member 2 being provided at one end of the panel material 1. The leg member 2 may be arranged and fixed so as to support the lower surface of the panel material 1 at the bottom, or the leg member 2 may be divided into short plates as shown in FIG. 3, and only some of the short plates may protrude from the side surface of the panel material 1. You can do it like this. In this case, the leg members 2 may be rotatably attached to the lower surface of the panel material 1 as shown in Fig. 3, and may be rotated during installation so that they protrude from the side. Leg member 2
It has the advantage of not being damaged and being easy to handle. Alternatively, as shown in FIG. 4, the leg members 2 may be integrally provided so as to be offset from each other and protrude from the four circumferential sides of the panel material 1.

Further, the opening 3 for the screw fixing work is the first
In addition to being formed by drilling as shown in the figure or FIG. 5, it may also be formed by notching as shown in FIG.

Moreover, the hollow panel as the panel material 1 is as follows:
In addition to the assembled panel formed by connecting the front and back materials 1a and 1b with the slat material 1c, an extrusion molded panel integrally formed by extrusion molding so as to have a hollow part inside as shown in Fig. 7 is also applicable. be. Furthermore, as shown in FIG. 8, a finishing material 1d such as a carpet may be integrated with the surface material 1a. Furthermore, as shown in FIG. 9, a laminate of plywood 1e and slate 1f is used as the front and back materials 1a and 1b,
By arranging the plywood 1e on the inside and the slate 1f on the outside and joining them with the timber 1c, the front and back materials 1a,
1b may be made hard and highly rigid.

Furthermore, a plurality of appropriately shaped through holes 4 reaching the hollow portion 5 of the panel material 1 are distributed and provided in the back surface material 1b of the panel material 1, as shown in FIGS. 7 to 9. Therefore, the air may flow on the lower surface side of the floor panel, and the radiated sound may be absorbed.

Next, to explain a method of constructing a dry floating floor using the floor panels of the above embodiments, as shown in FIG.
After a cushioning material 11 such as glass wool mat is laid entirely or partially on top of the cushioning material 11, the floor panels A are placed on the cushioning material 11 in a continuous manner in the horizontal direction.
In that case, the side end of the adjacent floor panel A on the side where the leg member 2 is not provided is placed on the leg member 2 protruding from the side end of the floor panel A, and the panel surface material 1
Using an electric screwdriver 12 or the like, use an electric screwdriver 12 or the like to insert the back material 1 of the adjacent floor panels A and A through the screw fastening opening 3 of A.
By repeating the process of fastening b and leg member 2 with screws 13, each floor panel A is tightly connected to each other to form a floating floor as shown in FIG. 11.

The floating floor formed in this way can be formed with good construction ease without the need to specially construct supporting materials such as joists as in the past, and can be constructed easily by using the leg members 2 integrated with the panel material 1. Therefore, the lower surface of the floor panel A and the upper surface of the leg member 2 of the adjacent floor panel A can be brought into close contact with each other and bonded together without causing sinking or inclination of the receiving material when screwed together as in the conventional case. As a result, even if a load or impact force is applied to the joint, the joint does not open downward, and the bending of the joint and the dent in the floor can be reduced, and a strong floating floor can be formed.

Furthermore, a floor panel A combined with the leg member 2
Since an opening 3 for screw fixing is previously provided at the other end in a position corresponding to the leg member 2, screws can be inserted through this opening 3 even if the position of the leg members 2 to be stacked is not visible. The floor panels A and A can be reliably connected together by simply stopping them.

In addition, the panel material 1 is made of a hollow panel to increase rigidity, and the panel back material 1b
Since the hollow panel is overlapped with the leg member 2 and connected, even if the surface material 1a of the hollow panel is made thicker to further increase the panel rigidity, the connection can be made only with the back material 1b regardless of this.

(Effects of the Invention) As explained above, according to the floor panel of the present invention, when the floor panel is installed in parallel in the horizontal direction on the floor subsurface with a cushioning material in between, the Since it can be connected to adjacent floor panels without the need for support materials such as joists using the leg members, floor panels can be easily and firmly connected to each other on flexible cushioning materials such as glass wool mats. . In addition, the floor panel base is made of a hollow panel, and the surface material is provided with an opening for screw fixing that reaches the hollow part of the panel at a position corresponding to the leg member, so that the sides of adjacent floor panels overlap each other. By just doing this, the leg members can be reliably connected even if the position of the leg members cannot be seen. In addition, openings are provided in the panel surface material and the leg members are connected only to the panel back material, allowing the use of thick or hard surface materials, resulting in excellent rigidity. Moreover, it is possible to maintain a strong bond without screws coming off. Furthermore, according to the construction method of the present invention, since the hollow panels are joined using the back material, there is no decrease in screw fastening workability even if the overall thickness of the panel material is increased, and construction can be performed quickly. Since the screw heads are also hidden inside the hollow panel, the screw heads do not protrude from the surface of the floor panel, and do not get in the way when floor finishing materials or disposable plywood are placed on the panel.
