  By the way, in the conventional leg member for flooring mentioned above, since the plate-shaped part has the same area as the lower surface of a flooring, the leg member was enlarged. For this reason, the manufacturing work of the leg member takes time and labor, and the manufacturing cost of the leg member is increased.

  An object of the present invention is to provide a floor member for a floor material that can reduce the overall size of the member, and a method for constructing a floor using the leg member for a floor material.

  A floor material leg member according to the present invention (hereinafter referred to as a “leg member”) is formed from a part of the lower surface of a floor material formed of a hard material provided on a soft rug member disposed on a floor base material. It is attached so as to protrude downward, and can penetrate into the soft rug member from above and reach the inside of the floor base material or the surface thereof or the vicinity thereof.

  In the present invention, the leg member protrudes downward from a part of the lower surface of the flooring. In other words, in the present invention, the leg member is smaller than the area of the lower surface of the flooring. Thus, unlike the conventional leg member, the leg member according to the present invention does not have the same plate-like portion as the area of the lower surface of the flooring, but is reduced in area. For this reason, according to this invention, size reduction of a leg member can be achieved.

  Further, according to the present invention, the weight of the leg member can be reduced and the manufacturing cost of the leg member can be reduced because the plate-like portion having the same area as the lower surface of the flooring material is not provided. become.

  Further, in the present invention, the leg member attached so as to protrude downward from a part of the lower surface of the flooring material penetrates into the soft rug member arranged on the flooring material from above, or the inside of the flooring material or It can reach its surface or its vicinity. Therefore, the leg member attached to the lower surface of the flooring material penetrates the soft rug member arranged on the flooring material from above and reaches the inside of the flooring material or the surface thereof or the vicinity thereof. A flooring made of material can be placed on the soft rug member. In particular, when the leg member can reach the inside of the floor base material, the stationary state of the floor material with respect to the soft rug member can be ensured.

  For this reason, according to this invention, compared with the conventional leg member, a flooring can be easily installed on a soft rug member.

  Here, the soft rug member includes carpets and carpets (for example, a hair part that forms a soft part and a base cloth that forms a hard base part) already installed on a floor base material such as a house or office. Or a heat insulating material or a sound insulating material (for example, glass wool, urethane foam, etc.) disposed on a floor base material in a new construction such as a house or an office.

  In addition, since it is said that it can penetrate into the soft rug member from above and reach the inside or the surface of the floor base material or the vicinity thereof, the leg member enters the soft rug member from above. It may be the one that reaches the inside of the floor base material, or the one that reaches the surface of the floor base material without reaching the inside of the floor base material, in the vicinity of the floor base material, that is, the inside of the soft rug member ( For example, it may reach a hair part forming a soft part or a base cloth forming a hard base part. In other words, the leg member may penetrate through the soft rug member after entering the soft rug member from above, or may not penetrate the leg member.

  In the present invention, the hard material forming the flooring material is arbitrary, for example, wood may be used, wood powder mixed with a synthetic resin adhesive, molded resin, synthetic resin, metal or the like may be used. .

  In addition, the flooring material may be a narrow one that is arranged in parallel in the width direction, or may be a small area panel-like one that is arranged in parallel in the front-rear direction and the left-right direction. It may be a face material and may be one or a few.

  In the present invention, the leg member may be made of metal, may be made of a synthetic resin, may be made of wood or the like.

  In the present invention, the shape and structure of the leg members are attached so as to protrude downward from a part of the lower surface of the flooring material, and can penetrate into the soft rug member from above and reach the inside of the floor base material or the surface thereof or the vicinity thereof. The leg member has an area smaller than the area of the lower surface of the flooring, and is provided with a load receiving portion that is coupled to the lower surface of the flooring and receives a downward load. It is preferable that

  According to this, even if a downward load is applied to the leg member that supports the underfloor main body upward, the support state of the leg member can be stabilized.

  In the present invention, the form and structure of the leg member provided with the load receiving portion are arbitrary, and as a first example, the lower surface of the load receiving portion extends downward from the lower surface and is long in the vertical direction. The thing provided with one columnar part which has thickness can be mentioned.

  Further, as a second example of the leg member provided with the load receiving portion, the load receiving portion has a flat plate shape, and the lower surface of the load receiving portion extends downward from the lower surface and extends in the vertical direction. The thing provided with the some columnar part which has the length of this can be mentioned.

  In the first and second examples of the leg member, when the load receiving portion is the first load receiving portion, the lower portion of the columnar portion has an area smaller than the area of the lower surface of the flooring, and the soft rug You may make it provide the 2nd load receiving part which contact | abuts to a member and receives a downward load.

  In the first and second examples of the leg member described above, an intrusion portion that can enter into the floor base material may or may not be provided in the lower portion of the columnar portion.

  According to the former case, the penetration portion penetrates into the floor base material, so that the stationary state of the floor material with respect to the soft rug member can be made more reliable than the latter case. Here, the type and structure of the intrusion part are arbitrary as long as they can penetrate into the floor base material. For example, a needle part that penetrates into the floor base material by driving with a tool such as a hammer (for example, Or a screw portion that penetrates into the interior of the floor base material by screwing with a tool such as a screwdriver (for example, it is pointed downward with a spiral thread groove on the surface) (Conical shape) or the like. On the other hand, in the latter case (when the intrusion portion is not provided in the lower portion of the columnar portion), the lower portion of the columnar portion is preferably fixed to the surface of the soft rug member or the floor base material with an adhesive or the like.

  In the case where the intrusion portion is provided at the lower portion of the columnar portion, when the intrusion portion is the first intrusion portion, a second intrusion portion that can enter the floor material is provided at the upper portion of the columnar portion. You may make it provide.

  According to this, the said leg member is couple | bonded with the lower surface of a flooring because the 2nd penetration | invasion part of the said columnar part penetrate | invades in the inside of a flooring. Here, the type and structure of the second intrusion portion are arbitrary as long as they can enter the interior of the flooring material, like the first intrusion portion. For example, the above-described needle portion (for example, pointed upward) Or a threaded portion (for example, a conical shape that is pointed upward with a spiral thread groove on the surface). In addition, when the 2nd penetration | invasion part which can penetrate | invade into the inside of a flooring is not provided in the upper part of the said columnar part, the upper part of the said columnar part is fixed to the lower surface of a flooring material with an adhesive agent etc.

  Further, in the first and second examples of the leg member described above, the floor material is provided only at the upper part of the columnar part without providing the lower part of the columnar part with an intrusion part that can enter the interior of the floor base material. You may make it provide the penetration | invasion part which can penetrate | invade to the inside.

  As a third example of the form and structure of the leg member, a flat horizontal portion coupled to the lower surface of the flooring and having an area smaller than the area of the lower surface, and a hanging portion extending downward from the horizontal portion, The horizontal portion may be a load receiving portion that receives a downward load. Here, the method of joining the horizontal portion to the lower surface of the flooring is arbitrary, and may be, for example, fastening with a fastening tool such as a screw or a nail, or adhesion by an adhesive or welding by welding.

  In addition, it is preferable to fix the front-end | tip (lower end part) of the said drooping part to the surface of a soft rug member or a floor base material with an adhesive agent.

  In the present invention described above, when a plurality of flooring materials are arranged side by side in the horizontal direction, the connection structure between the respective flooring materials is arbitrary, and the first example is in each flooring material. A fruit is formed on one of the two side surfaces opposite to each other, a groove is formed on the other side, and the fruit of one of the two flooring materials adjacent to each other is placed on the other flooring. It is connecting these flooring materials by fitting in a groove. Further, in the second example, one of two opposite side surfaces of each flooring is provided with an upper half step projection having a thickness of half of the flooring, and the other is provided with a flooring. The lower half of the protrusions for the step portion are formed by half the thickness, and two adjacent floor materials are connected by engagement of the protrusions for the step portion.

  In the first example of the connection structure between floor materials, the leg member is a fruit and a groove that fits into one of the fruit and the groove of the floor material arranged earlier on the lower surface of each floor material. It is preferable to provide in the position which approached the side surface side on the opposite side to the side surface in which the other is formed.

  According to this, when connecting the floor materials, the leg member does not come into contact with the soft rug member and the work is not hindered, so that the connection work between the floor materials can be easily performed.

  In the second example of the connection structure between the flooring materials, the leg members are the upper half step projections and the lower half of the flooring material disposed on the lower surface of each flooring material. The upper half of the step protrusion and the lower half of the step protrusion are fitted to one of the step protrusions, and the other half of the step protrusion is close to the side surface on the opposite side. It is preferable to provide in the position.

  In the present invention, the floor base material includes not only wooden materials but also those made of reinforced concrete (RC). In the latter case, in order to reach the leg member according to the present invention to the inside of the floor base material made of reinforced concrete, an anchor member is embedded in the floor base material in advance, and inside this anchor member, What is necessary is just to make the penetration | invasion part provided in the lower part of the columnar part of a leg member, the long nail etc. which penetrate a leg member reach.

  Even when the floor base material is made of wood, an anchor member is embedded in the wooden floor base material in advance, and the anchor member is provided below the columnar portion of the leg member. It is also possible to make the intrusion portion or the long nail penetrating the leg member reach.

  The floor construction method using the leg member according to the present invention described above is arbitrary, and the first example of this floor construction method is the step of attaching the above-described leg member to the lower surface of the floor material, And a step of installing the floor material to which the leg member is attached on the soft rug member. That is, this 1st example is the construction method which attaches a leg member to the lower surface of a flooring previously.

  Moreover, the 2nd example of the construction method of a floor has the process of installing the leg member mentioned above on a soft rug member, and the process of mounting and fixing a flooring to the said leg member next. It is characterized by this. That is, this 2nd example is the construction method which installs a leg member on a soft rug member previously.

  In the first example of the floor construction method, when there are a plurality of leg members installed on the soft rug member, a plate-like member having a length dimension that can be spanned between the plurality of leg members is provided. Then, after spanning the plurality of leg members, a level is placed on the upper surface of the plate-like member, and the horizontal state of the plate-like member is measured. When it is not indicated, it is preferable to include a step of arranging a height position adjusting member for adjusting the height position of the leg member on the leg member.

  According to this, the horizontal level of the floor material can be confirmed and adjusted before the floor material is placed and fixed on the leg member. That is, whether or not the height positions of the plurality of leg members installed on the soft rug member are uniform can be measured. If the height positions of the plurality of leg members are not uniform, the legs A height position adjusting member can be arranged on the upper part of the member to adjust the height positions of the plurality of leg members to be uniform.

  Further, in the first example of the floor construction method, when there are a plurality of leg members installed on the soft rug member, after the plurality of leg members are installed on the soft rug member, A plate-like member having a length dimension that can be installed on the plurality of leg members may be provided on the plurality of leg members.

  According to this, since the part to which the flooring is fixed (in other words, the part that supports the flooring upward) is increased by installing the plate-like member on the plurality of leg members, the rigidity of the flooring increases. Moreover, the height position of a flooring can be freely changed by changing the thickness dimension (vertical dimension) of a plate-shaped member. In addition, when the plate-like member is laid over a plurality of leg members, in other words, when the plate-like member is placed on the plurality of leg members, the level is placed on the upper surface of the plate-like member as described above. Further, it may be measured whether the height positions of the plurality of leg members are uniform.

  In the floor construction method according to the present invention described above, a plurality of flooring materials are arranged in parallel in the horizontal direction, and a fruit is formed on one of the two side surfaces on the opposite sides of each flooring material. When a groove is formed and the fruit of one of the two flooring materials adjacent to each other is fitted into the groove of the other flooring material and these flooring materials are connected to each other The leg member is a side surface on which the other of the fruit and the groove that fits into one of the fruit and the groove of the floor material arranged earlier is formed on the lower surface of each floor material. You may make it arrange | position in the position close | similar to the side surface of the other side.

  According to the present invention, it is possible to reduce the size of the leg member for flooring.

Further, the four prismatic portions 22 penetrate into the interior of the bristles 3B of the carpet 3, but are placed on the base cloth 3A without penetrating the base cloth 3A of the carpet 3. For this reason, the end surfaces of the lower end portions of the four prismatic portions 22 are second load receiving portions that contact the carpet 3 and receive a downward load. Although not illustrated, a plurality of leg members 20 are attached at regular intervals in the length direction of the flooring 6.

  Thus, the floor material 6 to be installed first is fixed on the carpet 3 in a state where the horizontal posture is more reliably maintained as shown in FIG. 4 by attaching the leg member 20 to the lower surface 6B. Be placed.

  Next, in the groove 6D of the first flooring 6 that is immovably disposed on the carpet 3 in this way, the actual floor 6C of the next flooring 6 that is disposed next to the flooring 6 (right adjacent in FIG. 4). At the same time, the plurality of leg members 10 attached to the lower surface 6B of the flooring 6 are placed on the carpet 3, and the needle portion 10D of the leg member 10 is allowed to enter the hair portion 3B of the carpet 3. Thereafter, in the same manner as described above, by hitting a position corresponding to the position of the lower surface 6B to which the leg member 10 is attached or a position near the upper surface 6A of the flooring 6 with a hammer 15 or the like from above, The needle portion 10 </ b> D of the leg member 10 is made to penetrate the interior of the base fabric 3 </ b> A of the carpet 3 to reach the interior of the floor base material 2.

  Next, as shown in FIG. 4, the same operation as described above is sequentially repeated for the other floor materials 6, and a plurality of floor materials 6 are juxtaposed in the width direction.

  The flooring 6 is juxtaposed close to the wall 12 opposite to the wall 11 shown in FIG. 4, and the remaining width dimension where the carpet 3 is exposed is smaller than the width dimension of one flooring 6. Then, the last flooring 6 is cut from the groove 6D side into a dimension that fits the remaining width dimension, and the leg member 10 is attached to the lower surface 6B of the flooring 6 that has become the small width. Note that. The last cutting work of the flooring 6 and the work of attaching the leg member 10 to the lower surface 6B of the flooring 6 having the small width may be performed in advance at the factory.

  After that, the processed 6C of the floor material 6 having a small width is fitted into the groove 6D of the floor material 6 previously arranged, and placed on the carpet 3 in the same manner as described above. Then, similarly to the above, by hitting a position corresponding to the position of the lower surface 6B to which the leg member 10 is attached or a position in the vicinity thereof on the upper surface 6A of the narrow flooring 6 with a hammer 15 or the like from above. Then, the needle portion 10D of the leg member 10 is caused to penetrate the interior of the base cloth 3A of the carpet 3 and reach the interior of the floor base material 2.

  After the above work is completed, the floor remodeling work is completed by attaching the baseboards 13 and 14 to the walls 11 and 12.

  In the present embodiment described above, the lower surface 6B of the flooring 6 that is installed to make the top of the carpet 3 that is a soft rug member disposed on the floor base material 2 a hard floor and is formed of a hard material. Unlike the conventional leg member having a plate-like portion having the same area as the flooring 6, the leg member 10 attached to the flooring has a smaller area than the area of the lower surface (bottom surface) 6B of the flooring 6.
