Description

  The present invention relates to a floor structure of a building.

  For example, in a building such as a house, a carpet may be laid as a floor finish in an indoor space such as a living room. Thus, when a carpet is used as a floor finishing material, it is generally performed by being adhered and fixed to the upper surface of the floor base material with an adhesive. This type of carpet was often used as a floor finish in the living room in the 1980s and 1990s.

  By the way, in recent years, remodeling of the floor portion from carpet finish to floor finish may be performed in accordance with changes in the needs of residents and deterioration of floor finish materials. In such a case, the carpet is first peeled off from the floor base material, and then a plurality of flooring materials are laid on the floor base material. However, the work of peeling the carpet from the floor base material is very laborious and has a great problem in terms of workability.

  In order to solve this problem, various techniques for directly laying a flooring material on the carpet without peeling the carpet from the floor base material have been proposed. For example, in Patent Document 1, a plurality of support legs for supporting the flooring material from below are provided on the lower surface side of the flooring material, and the flooring material is directly laid on the carpet by installing the support legs on the carpet. A configuration is disclosed. The support leg has a needle shape at the tip, and the tip reaches the upper surface of the floor base material in a state of being pierced by the carpet. Thereby, a support leg part is fixed to the floor base material, and the flooring material is fixed by extension. In this case, since the support legs are placed on the floor base material, a stable floor can be constructed despite the flooring material being directly installed on the carpet.

JP 2010-24642 A

  By the way, this kind of flooring material is designed to be connected by joining of actual peels, etc., and a fruit is provided on one of two opposing side surfaces, and a groove is provided on the other side. Yes. In this case, the flooring material of one of the two adjacent flooring materials is inserted into the groove of the other flooring material, so that these flooring materials are connected to each other.

  In view of the connection between the flooring materials by such actual strips, the technique of Patent Document 1 may cause the following problems. That is, in the process of installing the flooring material one by one on the carpet, when inserting the fruit of the flooring material to be retrofitted into the groove portion of the flooring material previously installed (pre-attached), the retrofitting flooring material And the fruit is inserted into the groove of the front flooring material. However, in the technique of Patent Document 1, the tip of the support leg has a needle shape. There is a possibility that the tip may get caught on the carpet hair (pile) or unevenness of the base fabric. In this case, it is considered that the retrofitting flooring material cannot be smoothly slid and it is difficult to smoothly perform the installation work of the flooring material.

  This invention is made | formed in view of the said situation, and makes it the main objective to provide the floor structure of the building which can make the installation operation | work of a hard floor material on a soft rug easy.

  In order to solve the above-mentioned problems, the floor structure of the building of the first invention is a building in which a soft rug is laid on a floor base material and a plurality of hard floor materials are laid on the soft rug. The end surfaces of the plurality of hard floor materials are connected together by joining, and a plurality of support legs for supporting the hard floor materials are provided on the lower surface side of the hard floor materials. The plurality of support legs are provided so as to extend in the same direction, and a lower end portion that receives a load from the hard floor on the soft rug is along a lower surface of the hard floor. It is a pointed end portion that has a longitudinal shape extending in the direction and is pointed downward, and the hard leg toward the one end side in the longitudinal direction is disposed at one end side in the longitudinal direction of the pointed end portion in the support leg portion. When sliding the material against the soft rug A hook portion that causes a hook is provided, and a non-hook portion that does not cause the hook to the soft rug when the hard floor material slides to the other end side in the longitudinal direction is provided on the other end side. It is characterized by.

  According to the present invention, the hard flooring is provided with a plurality of support legs, and the hard flooring is placed in the longitudinal direction of the pointed end of the support legs in a state where these support legs are placed on the soft rug. Can be slid. In this case, when the hard floor material is slid to one end side in the longitudinal direction of the pointed end portion and when it is slid to the other end side, the degree of catching of the support leg portion with respect to the soft rug is different. That is, when the hard flooring is slid to one end side in the longitudinal direction of the tip, the support leg can be slid without being caught by the soft rug, whereas when the hard floor is slid to the other end, the support leg is The slide is restricted by being caught on the soft rug. Therefore, when connecting the next hard floor material (hereinafter referred to as a retrofitted hard floor material) to the hard floor material (hereinafter referred to as a front hard floor material) that has been pre-coated on a soft rug, Place the post-attached hard flooring on the soft rug with the unhooked part of the part facing the pre-attached hard floor, and then slide the post-attached hard floor to the pre-attached hard floor. Thus, both hard flooring materials can be connected. In this case, the hard flooring can be connected smoothly. In such a connected state, since the slide to the side away from the front hard floor is restricted, the rear hard floor is fixed by nailing the rear hard floor to the floor base material. In this case, the rear hard floor material is prevented from being displaced to the separated side. Therefore, it is possible to avoid a troublesome operation such as performing a fixing operation while pressing the post-attached hard floor material with the legs so that the post-attached hard floor material is not displaced. Therefore, the installation work of the hard floor material on the soft rug can be facilitated as described above.

  In the building floor structure according to a second aspect of the present invention, in the first aspect, the support leg portion may incline upward from the one end in the longitudinal direction of the tip portion toward the other end side as the hook portion. Alternatively, the first surface portion that rises vertically from the one end, and the second surface portion that inclines upward from the other end in the longitudinal direction of the pointed portion toward the opposite side to the one end as the non-hooking portion. It is characterized by.

  Some soft rugs (such as carpets) have a base (base cloth) fixed to a base surface material and hairs (pile) extending upward from the base. In this case, in the present invention, the support leg portion is provided with a first surface portion that is inclined upward from one end in the longitudinal direction of the tip portion toward the other end side or rises vertically from the one end. When the hard flooring is slid to one end side in the direction, the first surface portion can be caught on the root of the hair and the mesh of the base. On the other hand, since the support leg portion is provided with a second surface portion that is inclined upward from the other end in the longitudinal direction of the tip portion toward the opposite side to the one end, it is hard to the other end side in the longitudinal direction of the tip portion. When the floor material is slid, it is possible to prevent the second surface portion from being caught on the base of the hair and the mesh of the base.

  The floor structure of the building of the third invention is the first or second invention, wherein the hard flooring has a quadrangular shape in which two adjacent sides are perpendicular to each other, and the plurality of support legs are The longitudinal direction of the pointed portion is provided at an angle that is oblique with respect to the end side of the hard flooring.

  In the case of sliding and connecting the hard floor material to the front hard floor material that is pre-tipped on the soft rug, in view of the work efficiency, it is adjacent to the hard floor material in the rear surface with a single slide. It is desirable to connect the end faces of the two sides to the end faces of the two leading hard floor materials. In this case, the direction in which the retrofitted hard flooring is slid is inclined with respect to the edge of the hard flooring. Accordingly, in the present invention, in view of this point, the hard flooring can be slid in the oblique direction by directing the longitudinal direction of the tip of the support leg to the end of the hard flooring. Yes. In this case, in the state in which the non-hanging part of the support leg is directed to the front hard floor material side, the rear hard floor material is slid obliquely with respect to the end side, thereby adjacent two rear hard floor materials. One end face can be connected to the end face of the leading hard floor at a time. Thereby, the effect of said 1st invention can be acquired, aiming at the improvement of work efficiency about the installation work of a hard flooring.

  In the floor structure of the building of the fourth invention, in the third invention, the hard flooring is provided with fruit on the end surfaces of the two adjacent edges among the four edges of the hard flooring, Grooves into which the fruits are inserted are provided on the end surfaces of the other two edges, and the hard floor materials are joined together by the fruits and the grooves. The plurality of support legs are inclined toward a predetermined direction defined as a direction toward the apex side of the two end sides provided with the groove, and the pointed end portion is the apex side in the predetermined direction. It is characterized by having the said non-hooking part in the edge part side.

  In the configuration in which the hard floor materials are connected to each other by actual cutting, the fruits are often provided on the end surfaces of the two adjacent edges in the hard floor material, and the grooves are provided on the end surfaces of the other two edges. In such a case, in view of the work efficiency, each groove provided on the two end surfaces of the hard floor material is slid two times ahead by sliding the retrofitted hard floor material obliquely with respect to its end side. It is conceivable to connect the attached hard flooring at once. And after connection, it is possible to fix the fruit of a retrofitted hard flooring to a floor base material using a nail etc. Therefore, in the present invention, in view of this point, the support leg portion is provided so as to be inclined in a predetermined direction defined as a direction toward the top side of the two end sides provided with the grooves in the hard floor material, and In the support leg portion, a non-hooking portion is provided on the end portion side of the tip portion that is the top portion side. In this case, in the state in which the non-hanging part of the support leg is directed to the front hard floor material side, the rear hard floor material is slid obliquely with respect to the end side, thereby adjacent two rear hard floor materials. Each groove on one end face can be connected to the fruit of two leading hard floors at once. Therefore, the same effect as that of the third aspect of the invention can be obtained in the configuration in which the fruit and the groove are connected with each other.

  In the building floor structure according to a fifth aspect of the present invention, in any one of the first to fourth aspects, a base sheet is fixed to a lower surface of the hard floor material, and the plurality of supports are provided on a lower surface side of the base sheet. The leg portion is provided integrally.

  According to the present invention, by fixing the base sheet to the lower surface of the hard floor material, the plurality of support legs provided integrally with the base sheet can be attached to the hard floor material at a time. Thereby, the attachment operation | work of a support leg part can be made easy compared with the case where a some support leg part is directly attached to a hard flooring.

  The floor structure of a building of a sixth invention is the installation for installing wiring or piping between the soft rug and the hard floor material by the support leg portion in any one of the first to fifth inventions. A space is formed, and the support leg portion is provided with a support portion that supports wiring or piping installed in the installation space.

  As shown in FIG. 1, the floor 10 of the building has a floor base material 11 provided on a joist (not shown). The floor base material 11 is formed of, for example, a particle board. A carpet (carpet) 12 as a soft rug is laid on the upper surface of the floor base material 11. The carpet 12 is fixed to the upper surface of the floor base material 11 with an adhesive.

  As shown in FIG. 2, the carpet 12 is made of an embroidery carpet (tufted carpet), a base fabric 14 (shown by hatching in FIG. 1) that is bonded to the floor base material 11, and an upper side from the base fabric 14. And a pile 15 as a bristle portion extending in the direction. A pile yarn is planted on the base fabric 14 by a sewing machine or the like, and a pile 15 is formed by the pile yarn. The pile 15 is made of a loop pile. For example, the rising length from the base fabric 14 (specifically, the rising length in a natural state) is about 5 mm.

  The carpet 12 is not limited to an embroidery carpet, and may be other carpets such as a woven carpet (for example, Wilton carpet). Further, the pile 15 may be a cut pile in which a loop is cut.

  On the carpet 12, a plurality of hard floor panels 20 are provided side by side in the horizontal direction. In the present embodiment, these hard floor panels 20 are installed on the carpet 12 at the time of renovation (renovation) of a building. The hard floor panels 20 are arranged in a grid pattern on the carpet 12 in plan view (see FIG. 5), and the adjacent hard floor panels 20 are connected to each other in the arrangement state. A substantially continuous floor finish surface 17 is formed by the plurality of hard floor panels 20.

  Next, the configuration of the hard floor panel 20 will be described with reference to FIG. 3 in addition to FIG. FIG. 3 shows the configuration of the hard floor panel 20, wherein (a) is a plan view showing the configuration, (b) is a front view, (c) is a bottom view, and (d) is a side view. .

  As shown in FIGS. 1 and 3, the hard floor panel 20 is provided on the lower surface of the hard floor finish 21 that forms the floor finish surface 17 and the hard floor finish 21, and supports the floor finish 21 from below. And a support member 22. The hard floor finish 21 is formed by flooring and has a narrow rectangular shape. In the present embodiment, a hard floor finish 21 having a length of 1800 mm on the long side and 300 mm on the short side is used.

  Two adjacent end faces (side surfaces) of the hard floor finish 21 are provided with a real part 26 (also referred to as a male solid) at an intermediate part in the thickness direction. The real part 26 is provided so as to protrude laterally from each end face, and is formed continuously in the extending direction of each end face. In the following, the real part on the long side is 26a, and the real part on the short side is 26b.

  On the other hand, two adjacent end surfaces (side surfaces) on the other side (that is, the side where the real part 26 is not provided) of the hard floor finish 21 are provided with a groove part 27 (also referred to as a female fruit) in the middle in the thickness direction. ) Is provided. The groove part 27 is formed continuously in the extending direction of the end face at each end face. In the following description, the groove portion on the long side is 27a, and the groove portion on the short side is 27b. The groove 27 is formed at the same position as the actual part 26 in the thickness direction of the hard floor finish 21, and the groove width is set to be substantially the same as the height of the actual part 26. Therefore, the groove part 27 and the real part 26 are fitted by inserting the real part 26 of the other hard floor finish material 21 into the groove part 27 of one hard floor finish material 21 among the adjacent hard floor finish materials 21. The hard floor finish materials 21 can be connected to each other. That is, it is possible to connect (join) the hard floor finish materials 21 with actual strips. Specifically, the long side real part 26a and the long side groove part 27a are fitted together, and the short side real part 26b and the short side groove part 27b are fitted together. It has become. Moreover, the real part 26 and the groove part 27 are equivalent to a connection part, respectively.

  Next, the support member 22 will be described based on FIG. 4 in addition to FIG. FIG. 4 is a perspective view showing a part of the support member 22.

  The support member 22 includes a base sheet 23 provided on the lower surface of the hard floor finish 21, and a plurality of support legs 24 attached to the lower surface of the base sheet 23. Both the base sheet 23 and the support legs 24 are made of the same resin material and are formed by integral molding. The base sheet 23 has substantially the same size (vertical and horizontal dimensions) as the hard floor finish 21.

  The support legs 24 are provided so as to protrude downward from the base sheet 23 and have a plate shape (vertical plate shape) extending along the lower surface of the base sheet 23. Specifically, the support leg 24 has an inclined surface 39 (tapered surface) that approaches as two opposing plate surfaces go downward, and the thickness decreases as the plate goes downward. A sharp pointed portion 31 is formed at the lower end of the support leg 24 by the two inclined surfaces 39. The pointed portion 31 has a linear shape extending in the length direction of the support leg 24 (horizontal direction orthogonal to the thickness direction), and is placed on the carpet 12 in the support leg 24 and is mounted on the hard floor panel 20 as will be described later. It is a part that receives the load.

  The support leg 24 is provided with a rising surface portion 35 that rises upward from one longitudinal end of the pointed portion 31. Specifically, the rising surface portion 35 rises in a direction orthogonal to the tip portion 31 (that is, the vertical direction), and therefore, a corner portion 37 that forms a right angle is formed between the tip portion 31 and the rising surface portion 35. ing. Here, the rising surface portion 35 corresponds to the first surface portion.

  On the other hand, the support leg 24 is provided with an arcuate surface portion 36 extending in an arc shape upward from the other end in the longitudinal direction of the pointed portion 31 toward the opposite side to the rising surface portion 35. The arc surface portion 36 has an arc shape that is convex toward the outside of the support leg 24, and is smoothly continuous with the tip portion 31. Specifically, at the boundary between the arcuate surface portion 36 and the tip portion 31, the circumferential direction of the arcuate surface portion 36 and the longitudinal direction of the apex portion 31 are the same direction. In other words, the circular arc surface portion 36 forms an angle of 180 ° (flat angle) with respect to the tip portion 31 at the end portion on the tip portion 31 side. Therefore, there is no corner between the tip 31 and the arcuate surface 36. Here, the arc surface portion 36 corresponds to the second surface portion.

  In the present embodiment, the vertical height of the support leg 24 is set to 3 mm. Therefore, in the configuration in which the hard floor finish 21 is supported from below by the support legs 24 on the carpet 12, the height of the floor 17 of the hard floor finish 21 is not as high as the floor height of the conventional carpet 12. Consideration is given.

  The support legs 24 are attached on the lower surface of the base sheet 23 such that the longitudinal direction of the pointed portion 31 is inclined with respect to the end side of the base sheet 23. Specifically, the support leg 24 is provided in a direction in which the longitudinal direction of the pointed end portion 31 forms an angle of 45 ° with respect to the end side of the base sheet 23.

  A plurality of support legs 24 (14 pieces in FIG. 3) are provided at predetermined intervals along the longitudinal direction of the base sheet 23 to form a support leg row. The support leg rows are provided in a plurality of rows (three rows in FIG. 3) at predetermined intervals along the short direction of the base sheet 23. In this case, the plurality of support legs 24 are disposed substantially uniformly over the entire area of the base sheet 23. Further, in such an arrangement state, a plurality of support legs 24 (three in FIG. 3) are provided side by side along the longitudinal direction of the tip portion 31.

  The support member 22 is fixed to the floor finishing material 21 by attaching the base sheet 23 to the lower surface (back surface) of the hard floor finishing material 21 with an adhesive. When the support member 22 is fixed to the hard floor finish 21, the tip 31 of the support leg 24 faces obliquely with respect to the longitudinal direction of the hard floor finish 21 (in other words, the end of the hard floor finish 21). Specifically, it is provided in an orientation that forms an angle of 45 ° with respect to the longitudinal direction. More specifically, the pointed portion 31 of the support leg 24 is inclined in a predetermined direction determined as a direction toward the top portion 33 side of the two ends provided with the groove portion 27 in the hard floor finish material 21. 24, an arcuate surface portion 36 is disposed at the end portion on the top 33 side. Therefore, in this case, the rising surface portion 35 of the support leg 24 is positioned on the real part 26 b side of the hard floor finish 21 in the longitudinal direction of the hard floor finish 21, and the arc surface portion 36 of the support leg 24 is the hard floor finish 21. It is located on the groove 27b side. Further, the rising surface portion 35 of the support leg 24 is positioned on the real portion 26 a side of the hard floor finish 21 in the short direction of the hard floor finish 21, and the arc surface portion 36 of the support leg 24 is a groove 27 a of the hard floor finish 21. Located on the side.

  The support member 22 is not necessarily fixed to the hard floor finish 21 with an adhesive, and may be fixed using a fixing tool such as a nail, a screw, or a staple. However, in this case, it is necessary to consider that the fixture does not protrude from the hard floor finish 21. In the present embodiment, it is assumed that the hard floor finishing material 21 and the support member 22 are integrated in advance as a hard floor panel 20 in a factory and are brought into the renovation site. However, the hard floor finish 21 and the support member 22 may be brought separately to the renovation site, and these two members may be integrated on the site.

  Next, the installation configuration of the hard floor panel 20 on the carpet 12 will be described.

  As shown in FIG. 1, each of the plurality of hard floor panels 20 is installed by placing support legs 24 of a support member 22 on the carpet 12. In such an installation state, the adjacent hard floor panels 20 are connected to each other by joining the end surfaces of the hard floor finishing materials 21 to each other. Specifically, among the adjacent hard floor finishing materials 21, the real part 26 of one hard floor finishing material 21 is inserted into the groove portion 27 of the other hard floor finishing material 21, so that each of the hard floor finishing materials 21. The finishing materials 21 are joined together and connected.

  Each hard floor panel 20 is fixed to the floor base material 11 by nails 41. The nail 41 is driven into the base portion of the real part 26 of the hard floor finish 21 obliquely from above, and hits the floor base material 11 through the hard floor finish 21, the support member 22 and the carpet 12. It has been.

  The support legs 24 are placed on the base fabric 14 on the carpet 12. Specifically, the pointed end portion 31 of the support leg 24 is placed on the base cloth 14, and the pointed end portion 31 is configured to receive a load from the hard floor finish 21 on the base cloth 14. In this case, since the pointed end portion 31 has a sharp shape, when the hard floor panel 20 is placed on the carpet 12, the support leg 24 passes between the piles 15 and the pointed end portion 31. Reaches the base fabric 14. For this reason, the pile 15 has a low possibility of being stepped on under the support leg 24, and even if it is stepped on, it is small. Therefore, the hard floor panel 20 is installed in a stable state on the relatively hard base cloth 14 on the carpet 12, thereby constructing a hard floor that does not fluff when walking on the carpet 12. ing.

  Further, as described above, in the present embodiment, since the height (3 mm) of the support leg 24 is smaller than the length (5 mm) of the pile 15, the support leg 24 is supported in the installed state of the hard floor panel 20. The pile 15 is slightly tilted by the base sheet 23 of the member 22. If it captures about this point, since the support leg 24 is mounted on the base fabric 14 of the carpet 12 in this state, most of the load of the hard floor panel 20 is supported on the hard base fabric 14. It is not supported by the pile 15. Therefore, although the pile 15 is slightly tilted by the base sheet 23, the hard floor panel 20 is installed on the carpet 12 in a stable state.

  By the way, in the present embodiment, the hard floor panel 20 can be slid in a state of being placed on the carpet 12, and will be described later when the hard floor panel 20 is installed on the carpet 12. As described above, the hard floor panel 20 to be retrofitted to the hard floor panel 20 that has been attached to the carpet 12 is connected by sliding. Hereinafter, the effect | action of the slide movement of the hard floor panel 20 is demonstrated.

  The support leg 24 is slidable in the longitudinal direction of the tip 31 while being placed on the carpet 12. Specifically, when the support leg 24 is slid to the arc surface portion 36 side in the longitudinal direction of the tip portion 31, the arc surface portion 36 is on the carpet 12 (specifically, the mesh of the base cloth 14 or the base of the pile 15). On the other hand, when it is slid without being caught, and when it is slid toward the rising surface 35 in the longitudinal direction of the tip portion 31, the rising surface 35 is caught by the carpet 12 and the sliding is restricted. Therefore, the support leg 24 and thus the hard floor panel 20 can be slid only to the arcuate surface 36 side in the longitudinal direction of the tip 31.

  Further, since the pointed end portion 31 of the support leg 24 has a sharp shape as described above, the support leg 24 passes between the piles 15 when the support leg 24 is slid on the carpet 12. However, the tip 31 is slid in a state where it is placed on the base fabric 14. Therefore, when the support leg 24 is slid, the pile 15 has a low possibility of being stepped on under the support leg 24, and even if it is stepped on, it is slight. Thereby, it is suppressed that the pile 15 becomes an underlay of the support leg 24, and the inconveniences, such as the slide of the support leg 24 being prevented, arise.

  Next, the procedure of installation work for installing the hard floor panel 20 on the carpet 12 during renovation will be described with reference to FIG. FIG. 5 is an explanatory diagram for explaining the installation procedure of the hard floor panel 20. In FIG. 5, for the sake of convenience, the ratio of the length in the longitudinal direction to the length in the short direction of the hard floor panel 20 is shown smaller than the actual length. In FIG. 5, the carpet 12 has two sides A and B which are orthogonal to each other. On the carpet 12, m hard floor panels 20 are laid along A, and n hard floor panels 20 are formed along B. Is laid. In this case, m hard floor panels 20 are laid in the X direction, which is the direction along A, and the operation is performed for n rows while moving in the Y direction.

  First, as shown in FIG. 5A, on the carpet 12, the first hard floor panel 20A is installed at a corner 47 between two orthogonal sides A and B. In this case, the hard floor finish 20A of the hard floor panel 20A is hard in a state where the two grooves 27a and 27b are directed to the sides A and B (specifically, adjacent sides A and B) of the carpet 12, respectively. The floor panel 20 </ b> A is placed on the carpet 12, and is fixed to the floor base material 11 with nails 41 in the placed state. Specifically, the hard floor panel 20A is installed in a state where the long side groove portion 27a faces the side A of the carpet 12 and the short side groove portion 27b faces the side B.

  Then, the operation | work which installs the next hard floor panel 20B next to the hard floor panel 20A previously attached (next to X direction) is performed. In this case, the hard floor panel 20B is first placed on the carpet 12 with the arcuate surface 36 side of the support leg 24 (in other words, the top 33 side of the hard floor finish 21) facing the hard floor panel 20A. To do. At this time, each groove part 27a, 27b of the hard floor finishing material 21B of the hard floor panel 20B is in a state of facing the sides A, B of the carpet 12, respectively. Thereafter, the hard floor panel 20B is slid in a direction oblique to the end of the hard floor finishing material 21B along the longitudinal direction of the tip 31 of the support leg 24, and the hard floor finishing material of the hard floor panel 20B is obtained. The real part 26b of the hard floor finishing material 21A of the hard floor panel 20A is fitted into the groove part 27b of 21B. Thereby, the hard floor finishing materials 21A and 21B are bonded together, and the hard floor panel 20B and the hard floor panel 20A are connected. In this case, the connection work of the hard floor panels 20 can be performed smoothly.

  After the hard floor panels 20 </ b> A and 20 </ b> B are connected to each other, the hard floor panel 20 </ b> B is fixed to the floor base material 11 with the nails 41. In this case, the hard floor panel 20B is restricted from sliding toward the rising surface portion 35, that is, to the side away from the hard floor panel 20A in the longitudinal direction of the tip portion 31, so the hard floor panel 20B is legged or the like. The nailing operation can be performed without pressing.

  Next, the hard floor panel 20C is installed next to the hard floor panel 20B (next to the X direction). Thereby, the installation of the hard floor panels 20A to 20C in the first row is completed.

  Next, an operation of installing the second row of hard floor panels 20D to 20F is performed. Here, as shown in FIG. 5B, first, an operation of installing the hard floor panel 20D arranged along the side B of the carpet 12 next to the hard floor panel 20A (next to the Y direction) is performed. In this case, as in the case of the installation of the hard floor panels 20A to 20C in the first row described above, the carpet 12 is first placed with the hard floor panel 20D facing the arc surface portion 36 side of the support leg 24 toward the hard floor panel 20A. Then, the hard floor panel 20 </ b> D is slid toward the hard floor panel 20 </ b> A along the longitudinal direction of the tip 31. Thereby, the real part 26a of the hard floor finish 21A is fitted into the groove 27a of the hard floor finish 21D, and the hard floor panel 20D and the hard floor panel 20A are connected. Thereafter, the hard floor panel 20 </ b> D is fixed to the floor base surface material 11 with nails 41.

  Next, as shown in FIG.5 (c), the hard floor panel 20E is installed in the position which is next to the Y direction of the hard floor panel 20B, and next to the X direction of the hard floor panel 20D. In this case, as in the case of the installation of the hard floor panel 20D, first, the hard floor panel 20E is placed on the carpet 12 with the arc surface portion 36 side of the support leg 24 facing the hard floor panels 20B and 20D. . Thereafter, the hard floor panel 20E is directed toward the hard floor panels 20B and 20D in a direction oblique to the end of the hard floor finish 21E along the longitudinal direction of the tip 31 of the support leg 24. Slide. Thereby, the real part 26a of the hard floor finish 21B is fitted into the groove 27a of the hard floor finish 21E, and the real part 26b of the hard floor finish 21D is fitted into the groove 27b of the hard floor finish 21E. That is, in this case, the groove portions 27a and 27b on the two adjacent end faces of the hard floor finish 21E are fitted into the real portions 26 of the hard floor finishes 21B and 21D, respectively, with a single slide. And thereby, the hard floor panel 20E is connected with respect to each hard floor panel 20B and 20D. Thereafter, the hard floor panel 20 </ b> E is fixed to the floor base surface material 11 with the nails 41.

  Thereafter, the remaining hard floor panels 20F, 20G,... Are sequentially installed on the carpet 12 in the same procedure. Then, when all the hard floor panels 20 are installed, a series of installation work is completed.

  As mentioned above, according to the structure of this embodiment explained in full detail, the following outstanding effects are acquired.

  A base sheet 23 was attached to the lower surface of the hard floor finish 21, and a plurality of support legs 24 were integrally provided on the lower surface side of the base sheet 23. Therefore, the base sheet 23 can be attached to the lower surface of the hard floor finish 21 to attach a plurality of support legs 24 to the hard floor finish 21 side at once. Thereby, compared with the case where the some support leg 24 is directly attached to the hard floor finishing material 21, the attachment operation | work of the support leg 24 can be made easy.

  The present invention is not limited to the above embodiment, and may be implemented as follows, for example.

  (1) In the above embodiment, the rising surface portion 35 (corresponding to the first surface portion) is provided so as to make a right angle with respect to the tip portion 31, but this is changed so that an acute angle is formed with respect to the tip portion 31. One surface portion may be provided. That is, the first surface portion is provided so as to incline upward from one end of the support leg 24 in the longitudinal direction of the tip portion 31 (the end opposite to the arcuate surface portion 36) toward the other end side (the arcuate surface portion 36 side). May be. Even in such a case, when the support leg 24 is slid to one end side in the longitudinal direction of the pointed end portion 31, the carpet 12 can be caught in the first surface portion.

  Moreover, in the said embodiment, although the circular arc surface part 36 was provided as a 2nd surface part, the 2nd surface part does not necessarily need to be formed in circular arc surface shape. For example, the support leg 24 has a second inclined surface that is inclined upward in a planar shape from the other end in the longitudinal direction of the pointed portion 31 (that is, the end opposite to the rising surface 35) toward the side opposite to the rising surface 35. A surface portion may be provided. In this case, the second surface portion is formed to form an obtuse angle with respect to the tip portion 31. Even in such a configuration, when the support leg 24 is slid to the other end side in the longitudinal direction of the pointed end portion 31, the second surface portion can be prevented from being caught on the carpet 12.

  (2) In the above embodiment, the support leg 24 is inclined at an angle of 45 ° with respect to the longitudinal direction of the hard floor finish 21 (in other words, the direction in which the end of the hard floor finish 21 extends). Although it is attached to the floor finish 21 in an inclined direction, the inclination angle may be an angle other than 45 ° (for example, an angle other than 45 ° out of 20 ° to 70 °). Further, the support leg 24 is oriented in a direction in which the longitudinal direction of the pointed portion 31 faces the same direction as the longitudinal direction of the hard floor finish 21, or in a direction perpendicular to the longitudinal direction of the hard floor finish 21. It may be attached to the hard floor finish 21. That is, you may attach the support leg 24 in the direction where the longitudinal direction of the pointed part 31 faces the same direction as the edge of the hard floor finish 21. In this case, when the retrofitted hard floor panel 20 is connected to the front hard floor panel 20, the retrofitted hard floor panel 20 can be connected by sliding in the end direction of the hard floor finish 21.

  (3) In the above embodiment, the plurality of support legs 24 are attached to the hard floor finishing material 21 via the base sheet 23, but this is changed and the plurality of support legs 24 are directly attached to the hard floor finishing material 21. Also good. For example, in FIG. 6A, a nail 62 is embedded in the support leg 24 so that a part protrudes upward from the support leg 24, and the nail 62 is supported by being driven into the hard floor finish 21. Legs 24 are fixed directly to the hard floor finish 21. In this case, since the height of the floor surface 17 of the hard floor finish 21 can be lowered by the thickness of the base sheet 23, the height of the floor surface 17 can be made closer to the height of the floor surface of the conventional carpet 12.

  Further, the support legs 24 are not necessarily fixed to the hard floor finish 21 by the nails 62, and may be fixed by other means. For example, as shown in FIG. 6B, a fixing member 64 made of sheet metal may be attached to the upper side surface of the support leg 24, and the support leg 24 may be fixed to the hard floor finish 21 by the fixing member 64. . The fixing member 64 includes a rectangular flat plate portion 65 and a small piece portion 66 that is bent upward at the four corners and has a sharp point. In this case, the support leg 24 can be fixed to the hard floor finish 21 via the fixing member 64 by driving the small piece portion 66 into the hard floor finish 21. In addition, as shown in FIG. 6C, the small piece portion 66 may be provided only at two corners that are diagonal in the flat plate portion 65.

  (4) In the above embodiment, adjacent hard floor finish materials 21 are connected (joined) by actual strips that fit the real part 26 of one hard floor finish material 21 into the groove 27 of the other hard floor finish material 21. However, the structure of the joining which connects these hard floor finish materials 21 is not limited to this. For example, in one of the adjacent end surfaces of the hard floor finishing material 21, one half of the plate thickness is cut off on one side of the opposing end surfaces, and the other side is cut off on the lower side by half the plate thickness. The floor finish materials 21 may be bonded together.

  (5) The wiring H may be installed in the space between the carpet 12 formed by the support legs 24 and the base sheet 23. An example is shown in FIG. FIG. 7 is a diagram illustrating a configuration around the support leg as viewed from one side in a length direction (a direction orthogonal to the thickness direction) of the tip portion of the support leg. The support leg 54 shown in FIG. 7 has a vertical height larger than that of the support leg 24 of the above embodiment (for example, the vertical height is 10 mm), and the support leg 54 provides a space between the carpet 12 and the base sheet 23. An installation space S in which the wiring H is installed is formed. In this installation space S, the wiring H is provided between a plurality of support leg 54 rows (between rows) arranged along the longitudinal direction of the tip end portion 55 of the support leg 54, and the tip end portion is between the rows. 55 extends along the longitudinal direction.

  Each support leg 54 provided on both sides of the wiring H is provided with a wiring support portion 57 that supports the wiring H. The wiring support part 57 extends from the support leg 54 to the side, and supports the wiring H from below. In addition, the wiring support portion 57 is provided below the wiring H, and thus plays a role of preventing contact between the wiring H and the pile 15 of the carpet 12. In this case, the space between the carpet 12 formed by the support legs 54 and the hard floor finish 21 can be used effectively as a space for the wiring H, and the wiring H can be supported by the wiring support portion 57, so that the wiring H Can be suitably installed in the same space.

  Further, in the installation space S, both the weak electric wiring (signal line) and the high electric wiring (power line) may be installed as the wiring H. In this case, by providing the low-power wiring and the high-power wiring on both sides of the support leg 24, these wirings can be arranged apart from each other by the support leg 24.

  In addition, instead of or in addition to the wiring H, piping such as floor heating piping may be installed in the installation space S.

  (6) As shown in FIG. 8, the wiring may be divided for each hard floor panel 20, and the divided wiring 58 may be integrally provided in advance for each hard floor panel 20. FIG. 8 is a bottom view of the hard floor panel 20 provided with the divided wiring 58. In FIG. 8, connectors 59 and 60 for connecting the divided wirings 58 to each other are provided at both ends of the divided wirings 58. Both connectors 59 and 60 can be connected to each other. In this case, when the hard floor panel 20B to be retrofitted is connected to the pre-attached hard floor panel 20A by sliding, the connector 59 of the hard floor panel 20A and the connector 60 of the hard floor panel 20B are connected, and the divided wiring 58 are electrically connected to each other. Thereby, when wiring is installed in the installation space S, the installation work can be facilitated.

  (7) In the state in which the real part 26 is inserted into the groove part 27, an elastic sheet having elasticity may be interposed in a compressed state in the gap between the real part 26 and the groove part 27. For example, such a state can be obtained by inserting an elastic sheet in advance to at least one of the surface of the real part 26 and the inner side surface of the groove part 27 and then inserting the real part 26 into the groove part 27. In this case, since the adhesiveness between the real part 26 and the groove part 27 can be enhanced by the elastic sheet, the real part 26 can be prevented from coming off from the groove part 27. Moreover, since the collision with the real part 26 and the groove part 27 which arise when a person moves on the hard floor panel 20 can be relieved with an elastic sheet, a soundproofing effect and a vibration-proofing effect can also be acquired.

  (8) In the above embodiment, flooring, that is, a wood-based board material is used as the hard floor finish material 21, but the hard floor finish material 21 may be formed of other hard materials such as resin and metal.
