られるという利点がある．Wooden flooring materials that are laid on subfloors finished with mortar, concrete, etc. have been known since Jubei. For example, as shown in Figure 4, a wooden substrate 1a such as wooden plywood
A wooden flooring material Aa is known in which a plurality of grooves B are arranged in parallel on the back side of a wood flooring material Aa and a cushion material C is adhered to the same backside. By the way, such a wooden flooring material Am is installed by being fixed to the subfloor by adhesive or nailing, and the soundproofing effect can be obtained by using WItb and Kuun-Yogi material C. However, such wooden flooring material A
In case a, although grooves b are provided, the wooden substrate 1a has no bending flexibility, and in order to obtain sufficient bending flexibility, the number of grooves b arranged in parallel must be increased or the depth dimension of grooves b must be changed. When ale is formed deeply, cracks are likely to occur on the surface of the wood decorative board 2 due to ale, which poses problems in terms of strength and surface design. Therefore, wooden flooring material Aa is installed on the subfloor without sufficient bending flexibility, and because it does not fit well with the subfloor, it is fixed by gluing or nailing to the subfloor. The material was then forcibly blended into the subfloor during construction. In this case, the construction involves work such as gluing or nailing, making the laying work cumbersome and making it extremely difficult to replace the wooden flooring material Aa. In addition, it becomes complicated to accurately process a large number of grooves b on the wooden substrate 1a, and the production and V8! There was a problem with the Noh mask. Moreover, as shown in Fig. 5,
A fitting protrusion 3a is formed at -ms of the wooden base material 1a, a fitting recess 4a is formed at the other end, and the two are fitted to connect the wooden flooring materials A ILt A M. However, when making such a connection, the fitting recess 4a is filled with an adhesive d to prevent the fitting from coming off. However, in the case where the adhesive d is filled in this way, there is a problem that the adhesive d protrudes when the adhesive d is inserted, and it is necessary to wipe it off. [Problems to be Solved by the Invention] The present invention was invented to solve the drawbacks of the conventional technology described above. It has good familiarity with the
Cracks do not easily occur on the surface side of the wood decorative board, there are no problems in terms of strength or surface design, it can be installed on the subfloor without any work such as gluing or nailing, and it has vibration suppression and To provide a flooring material that can provide sufficient soundproofing, can greatly increase its production, and can be easily and quickly connected. Means for Solving Problem E8] The flooring material of the present invention is a flooring material that is laid on a subfloor surface, and includes a thin wood decorative material on the surface layer of a flexible sheet-like base material 1. The plates 2 are laminated, a fitting protrusion 3 is formed at the -gA end of the base material 1, and a fitting bolt 4 into which the fitting protrusion 3 can be fitted is formed at the other end. A retaining protrusion 3@ is formed on one side of the protrusion 3 and the fitting recess 4, and a retaining protrusion 3IL engages with the other to prevent dislodging.A retaining recess 4a.
It is characterized by the formation of [Function] In this way, by laminating the thin wooden decorative board 2 on the surface layer of the flexible sheet-like base material 1, the flexible sheet-like base material 1 is free from warping like a wooden substrate. By imparting flexibility to the base material 1 to make it blend in with the subfloor surface, absorbing unevenness of the subfloor better, and coming into closer contact with the subfloor surface, the flooring material A This prevents slipping of the floor surface, making it easy to install (
The flexible sheet-like base material 1 suppresses the propagation of vibrations, improves soundproofing, avoids groove processing, increases productivity, and When used as the base material 1 for shaped products, it is easy to stabilize the dimensions by selecting a resin, it is easy to manufacture joints for joining adjacent parts, it is possible to reduce costs, and various additions can be made. In addition, a fitting protrusion 3 is formed at one end of the base material 1, and a fitting recess 4 into which the fitting protrusion 3 can be fitted is formed at the other end, A retaining protrusion 3a is formed on one side of the fitting protrusion l\ls3 and the fitting recess 4, and four retaining points 4m are formed on the other side to prevent the retaining protrusion 3a from coming out. By fitting the fitting protrusion 3 into the fitting bolt hole 4 and engaging the retaining protrusion 3a with the retaining recess 4a, the use of adhesive can be avoided and the flooring material A
．． The connection between A and A can be easily and quickly made, which is advantageous for floor-standing construction, and W4 for such connection! N. is also made easy to obtain. [Examples] Examples of the present invention will be described in detail below with reference to the drawings. A wood decorative board 2, such as a veneer (sliced veneer) made by thinly slicing wood and having wood grains, is laminated on the surface of a flexible sheet-like base material 1 made of plywood or resin. A fitting protrusion 3 is formed at one end of the material 1, and a fitting recess 4 is formed at the other end. The formation of the fitting protrusion 3 and the fitting recess 4 is performed simultaneously when the base material 1 is shaped. The wood decorative board 2 may be one in which a sliced veneer with a thickness of 0.25+u+~0.6m is lined with a dry-processed lauan veneer with a thickness of 1~2cm, or a veneer with a dry process of lauan veneer with a thickness of 1~2cm
! l. There are pieces that are only sliced veneers of a certain size, and such wooden decorative boards 2 can be laminated and glued to the base material 1 made of composite or resin molded products at the time of molding, or they can be glued separately! ? It is something to be worn, etc. As the base material 1, it is preferable to use, for example, a sound insulating sheet mixed with metal powder and having high sound insulating and soundproofing properties. In this way, by laminating the thin wooden decorative board 2 on the surface layer of the flexible sheet-like base material 1, the flexible sheet-like base material 1 will not warp like a wooden substrate. It has flexibility and adapts well to the subfloor surface, absorbing the unevenness of the subfloor and coming into closer contact with the subfloor surface. This suppresses the slippage of A and allows for easy installation (direct installation) without the need for gluing or nailing directly onto the subfloor. The flexible sheet-like base material 1 suppresses the propagation of vibrations and also improves soundproofing properties. This avoids groove machining and increases productivity. In addition, since the base material 1 of the shaped article is made of Hewei resin, it is easy to stabilize the dimensions by selecting the resin, and the fitting protrusion 3 and fitting recess 4 for coupling with the lglI contact are easy to achieve. It is easy to manufacture such joints. The fitting protrusion 3 has a first
As shown in the figure, a retaining projection 3a is formed, and four retaining points 4a are formed in the retaining recess 4a to prevent the retaining projection 3a from coming off. By fitting the fitting protrusion 3 into the fitting recess 4 and engaging the retaining protrusion 3a with the retaining recess 4a, the use of adhesive can be avoided and the flooring material The connection between A and A can be easily and quickly made, which is advantageous for floor construction, and the structure for such connection can be easily obtained. When connecting, as the fitting protrusion 3 is fitted, the lower piece 4b of the fitting recess 4
is elastically deformed downward, and after fitting, the lower piece 4b restores its original shape to ensure secure retention. Then slide it in the direction of the arrow B in Figures vJ2 and Figure 3 to move it toward the end of the wood and perform laying construction. The direction of arrow A in FIG. 3 indicates the direction in which the fitting protrusion 3 and the fitting recess 4 are fitted together. [Effects of the Invention J] In short, the present invention has the advantage that since a thin wooden decorative board is laminated on the surface layer of a flexible sheet-like base material, the flexible sheet-like base material does not warp like a wooden substrate. The flexibility of the base material allows it to blend in with the subfloor surface, absorbing the unevenness of the subfloor better,
By making more snug contact with the subfloor surface, it prevents the flooring material from slipping, making it easier to install (directly lay) the material without gluing or nailing directly onto the subfloor surface. It is also possible to suppress the propagation of vibration with a flexible sheet-like base material, improve soundproofing, avoid groove processing, and increase productivity.
When using it as a base material for a precept-shaped article, it is easy to stabilize the dimensions by selecting a resin, and it is also easy to manufacture joints to connect adjacent items, which also reduces costs. Added value can be added, and a fitting protrusion is formed at one end of the base material, a fitting place into which the fitting protrusion can be fitted is formed at the other end, and the fitting protrusion A retaining protrusion is formed on one side of the mating recess, and a retaining recess is formed on the other side to prevent the retaining protrusion from coming out. By fitting the retainer and engaging the retainer protrusion with the four retainers, the use of adhesive can be avoided.
This method has the advantage that the 4I connection between flooring materials can be performed easily and quickly, making it advantageous for flooring construction, and the configuration for such connection can be easily obtained.
