Description

  The present invention relates to a reinforcing leg for a floor panel which is attached to a place where a supporting leg is not provided in a floor panel which forms a wiring and piping space below and which reinforces the support of the top panel of the floor panel.

  Conventionally, some floor panels are laid on the foundation floor of a building to form a double floor, and wiring and piping are performed under the floor. The floor panel is configured to support the top plate by support legs, and a space for wiring and piping is formed below the top plate.

  The floor panel is, for example, as shown in FIG. 4. In FIG. 4, the floor panel 21 is formed in a plurality of prisms at predetermined intervals along the peripheral edge of a square plate-like substrate 23 of the floor panel body 22. A rectangular column support leg 25 is erected, and a square plate-like top plate 31 is placed on and supported by each upper end surface thereof. In addition, on the inner substrate 23 surrounded by the plurality of prism support legs 25, column support legs 26 formed in a columnar shape at appropriate intervals are erected, and the top plate 31 is similarly supported from below. Deflection due to a heavy object placed on the plate 31 is prevented.

  By the way, conventionally, when a plurality of floor panels 21 are laid side by side on the foundation floor surface 51 at the time of installation, the floor panel 21 does not fit in the indoor space that is dimensionally surrounded by the wall surface 52 of the building. In many cases, a protruding portion is generated in the floor panel 21 adjacent to the floor panel 21. Therefore, a wall edge process is performed in which the protruding portions of the substrate 23 and the top plate 31 of the floor panel main body 22 are cut at the CC cut line and the DD cut line in FIG. It is.

  However, by cutting the protruding portion of the substrate 23 of the floor panel main body 22 by such a wall-side treatment, there is no support leg at the cut end portion of the remaining floor panel main body 22, An unsupported empty space is generated, and a gap corresponding to the maximum distance between adjacent support legs is generated between the cut edge of the floor panel body 22 and the nearest cylindrical support leg 26. For example, when cutting is performed at the position shown in FIG. 4, as shown in FIG. 14, a gap of a distance L <b> 1 is formed between the cut end edge of the floor panel body 22 and the columnar support leg 26. As a matter of course, if the distance between the support legs of the floor panel 21 is large, the distance L1 between the separation is also large, and the empty space is also large. As a result, as shown in FIG. 15, when a leg portion such as heavy furniture is placed on the top plate 31 in the portion of the distance L <b> 1, or when the heel of a walking person is placed, the top plate 31 is bent with the support leg closest to the cut edge of the floor panel body 22 as a fulcrum, and the opposite end may jump up, which is very dangerous.

On the other hand, Japanese Utility Model Laid-Open No. 3-111735 discloses a technique for preventing the bending by installing a reinforcing leg at a position where the top panel of the floor panel is easily bent. The floor panel described in the above publication is provided with a plurality of reinforcing leg mounting portions on the back surface thereof, and the top plate is prevented from being bent by appropriately attaching the reinforcing legs to the reinforcing leg mounting portion at a place where bending is easy. Yes. Specifically, the reinforcing leg mounting part is formed with an insertion recess on the back surface of the floor panel, and the reinforcing leg is formed in a different diameter columnar shape in which the small diameter part is integrally connected to the upper end of the large diameter part. In addition, the small-diameter portion of the reinforcing leg is fitted into the reinforcing leg mounting portion of the floor panel so as to be attached to the reinforcing leg mounting portion.
Japanese Utility Model Publication No. 3-111735

  However, in the floor panel described in the Japanese Utility Model Laid-Open No. 3-111735, the reinforcing legs are attached to the reinforcing leg attaching portions provided on the back surface of the floor panel, so that the reinforcing leg attaching portions are formed. It cannot be installed in places that are not, and cannot be supported and reinforced. Therefore, when the floor panel is cut in the wall-side treatment, the reinforcing legs are often attached at positions separated from the cut edge of the floor panel in contact with the wall surface.

  Here, even if the separation distance between the reinforcing leg and the cut edge of the floor panel is small, furniture or the like is usually arranged near the wall, so the furniture is placed on the top plate where it is not supported by the reinforcing leg. In many cases, the load of furniture or the like is concentrated on a portion that is not supported by the reinforcing leg, and the top plate may bend at that portion. It is dangerous because the risk of tilting. In addition, people often go in and out of the doorways of the room, and the heel portions of shoes and high heels are often stepped on and bent on places where no reinforcing legs are attached. As a result, there is a risk of damaging the ankle, as well as danger.

  That is, the floor panel described in the above publication can only be attached to a portion where the reinforcing leg mounting portion is provided on the back surface thereof, the mounting location is limited, and there is a need for a location that contacts the wall surface. It cannot be freely installed anywhere. In addition, for the purpose of attaching the reinforcement legs only, a number of reinforcement leg attachment parts for which it is undecided where the reinforcement legs can be attached until the time when a wall treatment or the like is required are provided in advance on the back surface of the floor panel. Is also very uneconomical.

  Therefore, the present invention can reinforce the support of the top plate by freely attaching it to an arbitrary portion of the floor panel such as a gap with the wall by using existing support legs. It is an object of the present invention to provide a floor panel reinforcing leg and a floor device that can surely prevent bending of a plate.

The reinforcement leg of the floor panel according to claim 1 reinforces the support of the floor panel provided with a plurality of support legs at intervals, and is attached to the support leg of the floor panel in a non- rotating state. And a support portion that extends laterally from the mounting portion and supports the top panel of the floor panel, and the support portion is formed to be adjustable to an arbitrary length in the extending direction . In addition, the floor panel is formed to have the same length as the interval between the adjacent support legs .
The reinforcement leg of the floor panel according to claim 2 reinforces the support of the floor panel on which the support leg is formed, and includes an attachment portion attached to the support leg of the floor panel in a non-rotating state, and the attachment portion. A support portion that extends laterally and supports the top panel of the floor panel, the support portion is formed to be adjustable to an arbitrary length in the extending direction, and the attachment portion is the floor It is formed with a through hole that can be attached to the support leg of the panel from above and below.

  Here, the support legs of the floor panel are erected on the substrate constituting the floor panel and the top plate is placed on the upper surface portion, or the base plate is suspended downward from the back surface of the top plate. Placed on top. The support legs are formed in a columnar shape or a prismatic shape.

  The mounting portion of the reinforcing leg is attached to the supporting leg of the floor panel in a non-rotating state in order to securely position the supporting portion that supports the top plate at a position where the bending occurs. Specifically, when the support leg is formed in a prismatic shape, the support leg can be formed in a prismatic through hole corresponding to the support leg and fitted into the support leg to prevent rotation. When the support leg is formed in a columnar shape, as will be described later, it can be brought into a detent state by being fitted over two adjacent columnar support legs.

  The support portion of the reinforcing leg is formed on the side of the mounting portion, and is formed so as to support the top panel of the floor panel continuously or intermittently along the extending direction. The support portion is not limited to a portion that abuts on and directly supports the top panel of the floor panel, and includes other portions that are not directly supported by a portion extending to the side of the attachment portion. In addition, when supporting a top plate intermittently, the said support part may be one place, and may support a top plate in two or more places at intervals in the extending direction, but at least the said top plate It must be supported at the cut end. This is to prevent a load from being applied to the cut end portion of the top plate, bending the cut end portion of the top plate, and jumping up the other end portion.

  The support portion is formed so as to be adjustable to an arbitrary length in the extending direction. For example, in the wall edge processing, the support portion can be extended to a position very close to the wall surface. Adjustment to an arbitrary length can be performed, for example, by cutting at an arbitrary position as described later. Moreover, it can also be adjusted to arbitrary lengths by making a support part slidable in the extending direction with respect to an attachment part.

  The attachment portion and the support portion can be integrally formed by molding a synthetic resin. However, the attachment portion and the support portion may be separate structures, and in this case, only the attachment portion can be exchanged according to the type and shape of the support legs of the floor panel.

Next, the reinforcing leg of the floor panel according to claim 3 is formed so that the support portion can be cut at an arbitrary position in the extending direction. By forming the support portion from a synthetic resin or the like, it can be easily cut by a cutter or the like.

In the reinforcing leg of the floor panel according to claim 4, the support portion continuously supports the top plate. Thereby, even if the said support part cut | disconnects in the arbitrary positions in the extension direction, it will support the top plate of the said floor panel continuously to the cutting | disconnection edge part, ie, the whole support part. Further, even when the support portion slides in the extending direction with respect to the attachment portion, the top plate is supported by the entire support portion.

  The reinforcement leg of the floor panel according to claim 5 is one in which a plurality of support legs of the floor panel are provided at intervals, and the attachment portion is attached in a detent state across two or more adjacent support legs. It is.

State mounting portion according to claim 2, since the supporting legs of the floor panel is formed in the mounting through hole that allows the vertical direction, the reinforcing legs which support legs of the floor panel is fitted in the through hole of the mounting portion Installed in. In addition, when the said support leg is standingly arranged on the board | substrate of the floor panel mounted on a foundation floor surface, the through-hole of an attaching part is fitted by the said support leg from upper direction. Moreover, when the said support leg is hanged downward on the back surface of a top plate, the through-hole of an attaching part is fitted by the said support leg from the downward direction.

In the reinforcing leg of the floor panel according to claim 1 and 2 , the support portion for supporting the top panel of the floor panel is extended from the mounting portion to the side and can be adjusted to an arbitrary length in the extending direction. Unlike the conventional case where the reinforcing leg mounting portion for mounting the reinforcing leg is formed in advance and the reinforcing leg can be mounted only at the position of the reinforcing leg mounting portion, By adjusting the support part extended laterally from the attachment part to the leg to an arbitrary length, for example, in the wall processing, the support part is extended to a position very close to the wall surface, The top plate can be supported at the cut end of the panel. Moreover, it can attach using an existing support leg, without providing the reinforcement leg attaching part for attaching a reinforcement leg separately. Thereby, since the said support part can be freely attached to the arbitrary positions of a floor panel and the support of a top plate can be reinforced, the bending of the top plate which arises in a wall edge process etc. can be prevented reliably.

In the reinforcing leg of the floor panel according to claim 3 , since the support portion is formed so as to be cut at an arbitrary position in the extending direction, the support portion can be adjusted to an arbitrary length in the extending direction. it can.

In the reinforcing leg of the floor panel according to the fourth aspect , since the support portion supports the top plate continuously, the top plate can be stably supported by the entire support portion.

In addition, in the reinforcing leg of the floor panel according to claim 1 , since the support portion is formed to have the same length as the interval between the adjacent supporting legs, the floor panel can be cut at any position between the supporting legs. In the wall-side treatment, the cutting end can be attached to the support leg in a state of being very close to the wall surface.

  In the reinforcing leg of the floor panel according to claim 5, since the mounting portion is mounted across two or more adjacent supporting legs, the mounting portions are adjacent to each other even when the supporting legs are formed in a columnar shape. By mounting across two or more columnar support legs, the rotation can be prevented.

Further, in the reinforcing leg of the floor panel according to claim 2 , since the attachment portion is formed by a through hole that can be attached to the supporting leg of the floor panel from above and below, the reinforcing leg can be easily and non-rotated. It can be attached to the support leg.

  Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 to 3 show the reinforcing legs of the floor panel according to the embodiment of the present invention, FIG. 1 is a perspective view, and FIG. 2 is a perspective view of the reinforcing legs of FIG. 5 is a perspective view showing a floor panel to which the reinforcing legs of FIG. 1 are attached.

  1 to 5, the reinforcing leg 2 is attached to a supporting leg standing on a substrate 23 of the floor panel 21 to support a portion where the top panel 31 of the floor panel 21 is easily bent and supported by the supporting leg. Is to reinforce. Here, as shown in FIGS. 6 to 9, the floor device 1 is configured by attaching the reinforcing legs 2 to the floor panel 21.

  First, as shown in FIG. 4, the floor panel 21 includes a floor panel body 22 and a top plate 31. The floor panel 21 is placed on a foundation floor 51 of a building to form a double floor. A wiring and piping space is formed below 31. The floor panel main body 22 has a plurality of support legs integrally standing on a substrate 23 made of a square plate of 500 mm in length and width. Specifically, main support legs 24 formed in a square prism shape at the four corners of the substrate 23 are erected, and between the main support legs 24, substantially the same along the peripheral edge of the substrate 23. A prism support leg 25 formed in a rectangular prism shape at intervals is erected. Partition ridges 24a and 25a are formed on the upper surfaces of the main support legs 24 and the prism support legs 25, respectively, and the top plate 31 is formed on the upper surfaces of the main support legs 24 and the prism support legs 25. It is placed on the inside of the strip. Further, inside the substrate 23 surrounded by these support legs, cylindrical support legs 26 formed in a columnar shape at predetermined intervals in the vertical and horizontal directions to prevent bending when a heavy object is placed. Has been. The floor panel body 22 having these support legs is integrally formed by molding synthetic resin.

  On the other hand, the top plate 31 is formed in a square plate shape by a synthetic resin plate, a metal plate or the like, and a tile carpet 32 is placed on the upper surface to form an indoor floor. A plurality of floor panels 21 are laid on the foundation floor 51, and wiring materials and piping materials such as cables 53 are laid in the wiring and piping space formed below the top plate 31, The cable 53 and the like are inserted into a main pit formed between the prism support leg 25 and the column support leg 26. In this embodiment, as shown in FIG. 5, a plurality of floor panels 21 are juxtaposed in the same direction, and on both sides, a plurality of floor appliances such as outlets and grounds can be accommodated below the top plate. A floor panel 41 is laid. Panels (not shown) are also placed in the gaps between the floor panels 21 and the floor panel 41, and the tile carpet 32 is placed on the upper surfaces of these panels.

  Next, the reinforcing leg 2, which is a feature of the present invention, is composed of a mounting part 3 attached to the support leg of the floor panel 21 and a support part 7 that supports the top plate 31 of the floor panel 21 from below. It is integrally formed of resin or the like. The mounting portion 3 is formed with a prism mounting portion 4 attached to the prism supporting leg 25 of the floor panel 21 at the center thereof, and an end-side column mounting portion 5 mounted to the column supporting leg 26 at the end. A central column mounting portion 6 that is similarly mounted to the column support leg 26 is formed at the end of the prism column mounting portion 4 on the support portion 7 side. Each mounting portion is formed with a through-hole penetrating in the vertical direction corresponding to the shape of the support leg of the floor panel 21, and can be attached by being externally fitted to the support leg from above.

  The center interval between the end-side column mounting portion 5 and the center-side column mounting portion 6 is formed to be the same as the center interval between the two adjacent column support legs 26 in the floor panel 21, and these column mounting portions are By being attached to two adjacent column support legs 26 at the same time, the cylinder support legs 26 are attached in a non-rotating state. On the other hand, the prism mounting portion 4 is formed in a rectangular prism hole corresponding to the rectangular prism support leg 25 formed in the rectangular prism shape of the floor panel 21, so Mounted in a stopped state. In addition, although the said center side cylinder attaching part 6 is formed in the semicylindrical through-hole in the edge part of the prism mounting part 4 in this embodiment, you may form it in circular arc whose outer periphery is shorter than a semicircle. In addition, the through hole may be formed as an independent through hole spaced from the prism mounting portion 4.

  Next, the support portion 7 of the reinforcing leg 2 is provided so as to extend laterally from the mounting portion 3, that is, in the longitudinal direction of the mounting portion 3, and has a constant cross-section continuously up to the entire length in the extending direction. It is formed into a shape. The support portion 7 is formed to have substantially the same length as the interval between the adjacent support legs, and can continuously support the top plate 31 at any position between the support legs. However, as long as the bending of the top plate 31 can be prevented, it does not necessarily have to be the same length as the interval between the support legs, and does not hinder the formation of a slightly shorter length. Since the support portion 7 is formed integrally with the mounting portion 3 with synthetic resin or the like, it can be cut to an arbitrary length with a cutter or the like.

  The support portion 7 is formed in a constant cross-sectional shape in which a concave portion 8 is disposed in the center and a pair of convex portions 9 are connected to the left and right sides thereof, and the cross-sectional shape of the concave and convex portions has high rigidity. The upper surface of the convex part 9 reaches the entire length and is a mounting surface 9a on which the top plate 31 is mounted. As shown in FIG. 3, a narrow groove 10 is formed in the center of the bottom surface of the concave portion 8 along the length direction, and a screw 54 can be screwed into the narrow groove 10 from above. It has become. In addition, the said support part 7 is not restricted to this cross-sectional shape, For example, you may form in H shape, I shape, etc. Moreover, although the height is formed so as to reach the entire length to be constant, the cross-sectional shape does not have to be constant throughout the length.

Next, a method for attaching the reinforcing leg 2 to the attaching portion 3 of the floor panel 21 as a reinforcing material in the wall processing will be described with reference to FIGS. 4, 6 and 7.
Now, in the construction in which a plurality of rated floor panels 21 and the like are laid side by side on the basic floor surface 51, the end of the floor panel 21 interferes with the indoor wall surface 52 due to the relationship with the indoor space. Assume that a wall-side process for cutting the end portions of the floor panel main body 22 and the top plate 31 along the CC cutting line and the DD cutting line in FIG. 4 is necessary to adjust the end portion of the panel 21. Then, in FIG. 4, as the end portion of the floor panel main body 22 is cut and removed, the two columnar support legs 26a erected on this end portion are also removed. As a result, as shown in FIG. In addition, in the remaining floor panel main body 22, the column support leg 26 b that is erected in the same row as the removed column support leg 26 a and adjacent to the column support leg 26 a is separated from the cutting edge by a distance L 1. In other words, the top plate 31 is easily bent at the separated portion.

  Therefore, as shown in FIG. 6, the reinforcing legs 2 are attached to the columnar support legs 26b of the floor panel main body 22 and the columnar support legs 26c adjacent thereto from above. Here, prior to attaching the reinforcing leg 2, the length that the tip of the support portion 7 of the reinforcing leg 2 coincides with the cut edge of the floor panel body 22 when the reinforcing leg 2 is attached in advance. That is, the length of the support portion 7 is adjusted by cutting it with a cutter or the like so that the tip end portion of the support portion 7 is in contact with or very close to the wall surface 52. After this length adjustment, the reinforcing legs 2 are attached from above the columnar support legs. At this time, the end-side columnar mounting portion 5 and the center-side columnar mounting portion 6 of the mounting portion 3 of the reinforcing leg 2 are each formed with a through hole corresponding to the shape and size of each columnar support leg of the floor panel body 22. And the center distance between the end-side columnar mounting part 5 and the center-side columnar mounting part 6 of the reinforcing leg 2 is the same as the center distance between the columnar support leg 26c and the columnar support leg 26b of the floor panel body 22. Since it is formed, it can be easily attached by being externally fitted to two adjacent column support legs of the floor panel body 22 from above.

  FIG. 7 shows a state after the reinforcing legs 2 are fitted to the columnar support legs 26c and the columnar support legs 26b of the floor panel body 22. The reinforcing leg 2 has an end-side columnar mounting portion 5 and a center-side columnar mounting portion 6 formed in a circular cross section, and is fitted to the columnar support leg 26c and the columnar support leg 26b of the floor panel body 22, respectively. For this reason, it is attached to the floor panel body 22 in a non-rotating state. The reinforcing legs 2 are attached to two left and right portions of one floor panel main body 22. As a result, the end of the top plate 31 near the wall is in a state where it is easily bent at the intermediate portion thereof, but is supported by the two reinforcing legs 2, so that bending at the portion can be prevented.

Next, support and reinforcement by the reinforcing legs 2 when the floor panel 21 is cut at the position shown in FIG.
In FIG. 8, the floor panel main body 22 shows a structure in which the two prism support legs 25 on both sides are cut with a distance L2 away from the cutting edge, and the top plate 31 is separated at this separated portion. It is easy to bend.

  Therefore, similarly to the reinforcing legs 2 shown in FIG. 6 and FIG. 7, when the reinforcing leg 2 is attached to the distal end of the supporting part 7 of the reinforcing leg 2 in advance, Cut to a length that matches, with a cutter or the like, and adjust the length. Thereafter, as shown in FIG. 8, the reinforcing legs 2 are attached from above the prism support legs 25 b of the floor panel body 22. At this time, since the prism mounting part 4 of the mounting part 3 of the reinforcing leg 2 is formed with a through hole corresponding to the shape and size of the prism support leg 25 of the floor panel main body 22, the floor panel main body 22 from above. It can be easily attached by being externally fitted to the prism support leg 25b.

  FIG. 9 shows a state after the reinforcing legs 2 are fitted to the prism support legs 25b of the floor panel body 22. Here, since the prism mounting part 4 of the reinforcing leg 2 and the prism supporting leg 25 of the floor panel main body 22 are formed in a prismatic shape, the reinforcing leg 2 is attached to the floor panel main body 22 in a non-rotating state. The reinforcing legs 2 are attached to two left and right ends of one floor panel main body 22. As a result, the end portions of the top plate 31 near the wall are in a state of being easily bent at both sides thereof, but are supported by the two reinforcing legs 2, and can be prevented from being bent due to a load at that portion.

Next, the operation of the reinforcing leg of this embodiment will be described.
In the reinforcing leg 2 of the present embodiment, the support portion 7 is continuously provided laterally from the attachment portion 3, and the support portion 7 can be cut at an arbitrary position in the extending direction. The support portion 7 may be cut to a length matching the cutting position of the floor panel 21 and attached to the support leg of the floor panel 21 with its cut end abutting against or in close proximity to the wall surface 52. The top plate 31 can be supported continuously up to the cut edge of the floor panel 21. Thereby, the bending of the top plate 31 which occurs in the wall side processing can be prevented, and the top plate can be reliably prevented from being flipped up due to the inclination of the furniture or the person's heel on the walk.

  And since the attaching part 3 can be attached over two adjacent column support legs 26 in the end side cylinder attaching part 5 and the center side cylinder attaching part 6, it can be attached to the support leg of the floor panel 21. Even if it is formed in a columnar shape, the end portion column mounting portion 5 and the center side column mounting portion 6 are fitted across the two adjacent column support legs 26, so that the mounting portion 3 is fixed. Can be installed in a non-rotating state. In addition, if the said attaching part 3 will be attached over two adjacent column support legs 26, it will be in a detent state, However, It does not prevent attaching over three or more column support legs 26.

  Further, since the reinforcing legs 2 can be attached to both the support legs 25 and the cylindrical support legs 26 in the attachment portion 3, the cost of the members can be reduced, and the management of storage and transportation of the members can be facilitated. Become.

  Furthermore, since the attachment portion 3 is formed with a through hole that can be attached to each support leg of the floor panel 21 from above and below, the reinforcing leg 2 can be easily attached to the support leg in a non-rotating state. Can do.

  By the way, although the reinforcement leg 2 of the said embodiment is formed in the same height as the support leg of the floor panel 21 in the attachment part 3 and the support part 7, the said attachment part 3 is each support leg of the said floor panel 21. Since it should just be able to attach in a rotation-stopping state, you may form lower than the said support leg. For example, only the mounting portion 3 can be formed in a flat plate shape extending in the horizontal direction at an intermediate height, as shown in FIG. In this case, the material cost can be reduced.

  In addition, the reinforcing leg 2 of the above-described embodiment takes into account the case where the reinforcing leg 2 is attached to the cylindrical support leg 26 of the floor panel 21, and the mounting part 3 includes two columns, that is, an end-side cylindrical mounting part 5 and a central-side cylindrical mounting part 6. Although the attachment part is provided, it is not necessarily restricted to this. For example, on the bottom surface of the recess 8, a screw 54 is inserted from above into the narrow groove 10 through the narrow groove 10 formed in the center in the width direction, and further screwed to the substrate 23 of the floor panel body 22. Thus, the reinforcing leg 2 can be attached in a non-rotating state by the end-side columnar mounting portion 5 and the screw 54 attached to the narrow groove 10. Therefore, in this case, it is not necessary to form the center-side columnar mounting portion 6.

  Alternatively, as shown in FIG. 11, considering that the front end surface of the support portion 7 of the reinforcing leg 2 is close to the wall surface with a very small gap, the reinforcing leg 2 is horizontal with the end side column mounting portion 5 as the center. Even if it is going to rotate in the direction, the tip corners 7a on both sides of the support part 7 abut against the wall surface 52 and the rotation in either the left or right direction is restricted. It can be attached in a non-rotating state, and the center-side cylindrical attachment portion 6 can be omitted. In this case, the total length of the reinforcing legs 2 is shortened by a length corresponding to the radius of the central column mounting portion 6, and the end column mounting portion 5 is moved closer to the square column mounting portion 4 side so that the prism mounting portion By shortening the interval with 4, the reinforcing leg 2 can be shortened.

Next, a reinforcing leg according to another embodiment of the present invention will be described with reference to FIG.
In the above embodiment, the reinforcing leg 2 integrally forms the attachment portion 3 and the support portion 7, but it can also be a separate structure. In FIG. 12, the reinforcing leg 2 includes a mounting portion 3 and a support portion 7 which are separately formed, and are slidably connected via a dovetail groove 12 and a screw 54. That is, the mounting portion 3 is provided with a prismatic mounting portion 4, an end-side columnar mounting portion 5, and a center-side columnar mounting portion 6 in the same manner as the mounting portion 3 of the above embodiment. On the other hand, the entire support portion 7 is formed in a substantially U-shaped plate shape, and slides in the horizontal direction on the outer surface side of the mounting portion 3. Here, the upper surface of the support portion 7 is a support surface that supports the top plate 31.

  Specifically, dovetail grooves 12 are formed in the inner walls of the U-shaped left and right side plate portions 11 of the support portion 7 along the length direction. Although not shown in the drawing, an engagement protrusion that engages with the dovetail groove 12 is formed along the length direction on the outer surface of the side wall, and the support portion 7 extends in the length direction, that is, extends with respect to the attachment portion 3. It slides in the installation direction. Further, a screw hole 13 is formed in the side plate portion 11 of the support portion 7, and a screw 54 is threaded through this to press the support portion 7 on the outer surface of the side wall of the mounting portion 3. The panel 21 can be held at a length that matches the cut edge.

  In order to attach the reinforcing leg 2 to the support leg of the floor panel 21, the support part 7 is fitted to the support leg of the floor panel 21 from above with the support part 7 being slightly moved toward the attachment part 3. The portion 7 is slid and its tip surface is brought into contact with the wall surface 52. Next, the screw 54 is tightened and the left and right side wall outer surfaces of the mounting portion 3 are pressed by the tip portion. Thereby, the said support part 7 is hold | maintained at predetermined length.

  In the case of this reinforcing leg 2, a two-member configuration is required, which increases the cost. However, by simply moving the screw 54 forward and backward and sliding the support portion 7, the extension length can be set to a predetermined length. It is possible to save the trouble of cutting. Thereby, the top plate 31 can be easily supported continuously along the extending direction on the upper surface of the support portion 7, and bending can be prevented.

  Further, as shown in FIG. 13, the reinforcing leg 2 can be attached with a spring material and elastically urge the support portion 7 toward the anti-attachment portion 3. In FIG. 13, the attachment part 3 is the same as the attachment part 3 of each said embodiment. On the other hand, the support portion 7 is formed in a rectangular frame plate shape, and the bottom surface is not shown in the figure, but at least the support legs of the floor panel 21 have a gap that can be inserted from below, and the left and right end portions extend along the longitudinal direction. A flange on which the mounting portion 3 is placed is provided. The upper surface of the support portion 7 is a support surface that supports the top plate 31. A coil spring 14 having one end in contact with the end of the mounting portion 3 and the other end in contact with the inner wall surface on the front end side of the support portion 7 is attached to the internal space of the support portion 7. The coil spring 14 always urges the inner wall surface on the front end side of the support portion 7 in a direction away from the mounting portion 3.

  A coil spring 14 is attached to the reinforcing leg 2, and the support portion 7 always slides in the extending direction with respect to the attachment portion 3 while being urged toward the cut edge of the floor panel 21. It has become. Therefore, in order to attach the reinforcing leg 2 to the support leg of the floor panel 21, the attachment part 3 is moved from above with the support part 7 slightly compressed toward the attachment part 3 against the urging force of the coil spring 14. If the hand is released after being fitted to the support leg of the floor panel 21, the support part 7 naturally slides toward the cut edge of the floor panel 21 by the urging force of the coil spring 14 and elastically moves to the wall surface 52. Abut.

  In the case of this reinforcing leg 2, a two-member structure is required, which increases the cost. However, by simply sliding the support portion 7 against the urging force of the coil spring 14, the front end surface of the support portion 7 is automatically moved. It abuts against the wall surface 52 and supports the top plate 31 continuously along the extending direction on the upper surface of the support portion 7 to prevent bending. Accordingly, it is possible to easily attach to the support leg of the floor panel 21 without saving the trouble of cutting the support portion 7 and screwing the screw 54 back and forth like the reinforcing leg 2 of FIG.

  Further, as described above, when the attachment portion 3 and the support portion 7 are formed separately and connected to each other, the attachment portion 3 corresponds to an arbitrary shape of the support legs of the floor panel 21. If it is formed and can be exchanged as a dedicated part, and the support portion 7 is shared, the cost of the member can be reduced to cope with various support legs, and the attachment portion 3 can be shortened.

  By the way, in each said embodiment, although the support part 7 is formed in the length substantially the same as the space | interval of an adjacent support leg, if the leg part of furniture, etc. are not located, or a person may rest. If not, it does not necessarily have to be cut to the same length as the interval between adjacent support legs.

  Moreover, although the support part 7 of the reinforcement leg 2 of each said embodiment is formed in the rectangular shape of the fixed width, the upper surface in which the top plate 31 of the floor panel 21 is mounted is not restricted to this, For example, the width of the upper surface may be varied in the extending direction, for example, by widening the tip near the wall surface 52.

  Furthermore, although the reinforcement leg 2 in the said embodiment has shown what was attached to the proximity | contact position of this wall surface 52 in order to prevent the bending in the wall surface 52 vicinity of the top plate 31 which arises by a wall edge process, the attachment of the said reinforcement leg 2 is shown. The location is not limited to this, and when a heavy object is placed at the center of the floor panel 21 or the like, it can be attached directly below, thereby reinforcing the support at the center or the like. Can do.

  In addition, the reinforcing leg 2 of the above embodiment is attached by fitting the attachment portion 3 formed in the through hole to the support leg of the floor panel 21, but it is attached at a predetermined position by adhesion or fixing with screws. It does not prevent.

  And although the reinforcement leg 2 of the said embodiment has shown what was applied to the floor panel 21 provided with the prism support leg 25 and the column support leg 26, the floor panel 21 provided with the support leg of another form is also shown. It goes without saying that the same applies.

  Moreover, although the reinforcement leg 2 of the said embodiment has shown what is attached to the support leg of the floor panel 21, it is not restricted to this. For example, the floor panel 41 accommodates a wiring device. Generally, since the top plate is supported by a large number of supporting wall materials or the like, it is additionally reinforced even if the end portion is cut during the wall processing. Although it is not necessary to attach and reinforce the legs, the reinforcing legs 2 may be attached in the same manner as the floor panel 21 if the top plate 31 may be bent.
