Description

  The present invention relates to a floor plate fixture for fixing a wooden deck or flooring floorboard on a support material such as joists, and more specifically, a side wall that forms both ends in the width direction has slits continuously in the length direction of the floorboard. The present invention relates to a floor plate fixture for fixing the formed floor plate on the support material.

  Taking a wood deck as an example, the construction of this wood deck is performed by, for example, as shown in FIG. 11, a bundle column 6 on an installation surface (not shown) formed by placing a foundation on the ground surface as necessary. A support member 5 such as a joist is erected on the bundle pillar 6, and a deck panel which is a floor plate 4 is placed on the support member 5 in parallel in a certain direction with a predetermined interval. This is done by fixing the floor plate 4 to the support material 5.

  The simplest method for fixing the floor plate 4 to the support member 5 is to drive a nail or screw nail from the surface of the floor plate 4 to the support member 5 and to directly fix the floor plate 4 to the support member 5 with this nail or screw nail. There is a way to put it.

  However, when this method is used, the head of the nail or screw nail is exposed on the surface of the floor plate 4 so that it does not look good. If the head of the nail or screw nail protrudes from the surface of the floor plate 4 over time, There is danger when walking on the floorboard.

  Furthermore, once the floorboard 4 once constructed is removed, the holes drilled by the nails and screw nails remain on the surface of the floorboard 4, so that the used floorboard collected from a dismantled house, etc. is re-used. If it is to be used, complicated work such as filling the hole is required.

  Accordingly, a method of attaching the floor plate 4 to the support member 5 using the floor plate fixture 1 without directly driving nails or screw nails into the surface of the floor plate 4 has been proposed. In order to make it possible, a slit 41 that is continuous in the length direction of the floor plate 4 is formed on the side surfaces 43 that form both ends in the width direction of the floor plate 4, and the floor plate is fitted in the length direction of the slit 41 at a predetermined interval. Fixing the fixture 1 on the support material 5 is performed.

  As described above, as an example of the floor plate fixture 1 for fixing the floor plate 4 to the support member 5, the floor plate fixture 1 shown in FIG. 11 includes two upper and lower horizontal plates 7, 8, and the horizontal plate 7, 8 is a metal floor plate fixture that is formed by a vertical plate 9 that vertically connects between 8 and has a substantially horizontal H shape in a cross-section in the width direction (see Patent Document 1), and the end of the upper horizontal plate 7 The edge is inserted into the slits 41 and 41 formed in the side surfaces 43 and 43 of the floor plates 4 and 4, and the lower lateral plate 8 is fixed on the support member 5 with screw nails, The floor plate 4 is fixed to the support material 5.

Prior art document information of the present invention includes the following.
Japanese Patent Application Laid-Open No. 2006-177066

  In the floor plate fixture 1 configured as described above, the edge of the upper horizontal plate 7 is inserted into the slit 41 formed in the side surface 43 of the floor plate 4, and the lower horizontal plate 8 is attached to the lower horizontal plate 8. When a screw nail or the like is driven into and fixed to the support member 5 through the formed hole 81, the floor plate 4 is restricted from moving away from the support member 5 (upward movement).

  However, in the floor plate fixture 1 shown in FIG. 11, even if the lower lateral plate 8 is fixed to the support member 5, the floor plate 4 has a gap between the back surface 42 and the back side inner wall 41 a of the slit 41. Since it is only inserted between the upper and lower horizontal plates 7 and 8 of the fixture 1, the floor plate 4 moves in the length direction (for example, the front side or the back side in FIG. 11). There is no means to regulate this.

  Therefore, in the floor board fixture 1 described in the above-mentioned Patent Document 1, a hole 91 is also formed in the vertical board 9, and a screw nail is formed on the side face 43 where the slit 41 of the floor board 4 is formed through the hole 91. By fixing the floor plate fixture 1 to the floor plate 4, the movement of the floor plate 4 in the length direction is restricted. As a result, when mounting the floor plate 4, screw nails in both the vertical and horizontal directions are controlled. It is necessary to drive in.

  Further, since the work space for driving the screw nails is required to fix the floor plate fixture 1 to the side surface 43 of the floor plate 4 as described above, one of the opposing side surfaces 43 of the floor plate 4 that is attached adjacently ( When the floor plate fixture 1 is attached to the side surface 43 of the floor plate 4 on the left side of FIG. 11, the side surface 43 (the side surface 43 of the floor plate 4 on the right side of FIG. 11) is opposed to the side surface 43. The common floor board fixture 1 cannot be fixed with a screw nail or the like.

  For this reason, when such a floor plate fixture 1 is used, the floor plate 4 and the floor plate fixture 1 are fixed only on one side in the width direction of the floor plate 4. When play between the horizontal plates 7 and 8 and the play between the upper and lower horizontal plates 7 and 8 between the inserted portions of the floor plate 4 causes rattling on the floor plate 4, The floor plate 4 and the floor plate fixture 1 or the floor plate 4 and the support member 5 come into contact with each other and collide with each other, thereby generating noise and the like.

  Further, as described above, in order to attach the floor plate fixture 1 to the side surface 43 of the floor plate 4, a work space for doing this is required. There are also restrictions on the construction method.

  That is, if the floor plate 4 is to be attached by the floor plate fixture 1, first, the floor plate fixture 1 is attached to one side surface in the width direction of the floor plate 4, and the floor plate to which the floor plate fixture 1 is thus attached is attached. 4 is placed on the support member 5, and the lower side plate 8 of the floor plate fixture 1 is fixed on the support member 5 with screw nails or the like, and then the floor plate 4 disposed adjacent to the floor plate 4 The floor plate 4 is supported by the support member 5 so that the upper side plate 7 of the floor plate fixture 1 having been attached is inserted into the slit 41 formed in the side surface 43 where the floor plate fixture 1 is not attached. The lower side plate 8 placed on the other side wall 43 and fixed to the other side wall 43 is fixed on the support member 5, and the necessary number of floor plates 4 are attached while repeating this operation.

  Further, when removing the floor plate 4, the floor plate fixing tool 1 of the floor plate 4 having the construction order later is removed from the support material 5 and removed, and then the adjacent floor plate 4 is removed. For example, even when only one floor plate 4 arranged near the center of the floor surface is replaced, it is necessary to remove all the floor plates 4 from the end to the floor plate 4 that needs to be replaced. It is complicated.

  In the floor plate fixture 1 described in Patent Document 1, when the floor plate 4 is expanded, the entire floor plate fixture 1 is prevented from being damaged. A configuration is adopted that absorbs the increase in dimensions during expansion by deforming this part by forming a thin part in the part (see, for example, FIGS. 1 and 2 of Patent Document 1). Although the allowance for the expansion in the width direction of the floor board 4 is provided, no consideration is given to the deformation in the length direction that may cause a large dimensional change upon expansion and contraction. Since the floor plate 4 is fixed to the floor plate 4 with screw nails, if the floor plate 4 expands and contracts in the length direction, the floor plate fixture 1 may be damaged.

  Further, if it is intended to prevent the floor plate fixture 1 from being damaged due to warpage or distortion that may occur in the floor plate 4 due to expansion or contraction of the floor plate 4, the inner wall of the slit 41 from the back surface 42 of the floor plate 4 to be fixed. It is necessary to deal with the length h between 41a by increasing the play by increasing the distance H ′ between the upper and lower horizontal plates 7 and 8, and the damage due to the expansion of the floor plate 4 in the width direction. The above-described thin wall portion provided for prevention is not restored to its original shape once it is deformed. Therefore, when the floor plate 4 contracts again due to a decrease in temperature or humidity, the contracted portion and the floor plate 4 become large. Play will occur.

  In this way, due to the rattling of the floor board 4 due to play between the floor board 4 and the floor board fixture 1, the noise generated when the floor board 4 collides with the support material 5 when walking on the floor board 4 is relatively large. It will be a thing.

  Therefore, the present invention has been made in order to eliminate the various drawbacks of the prior art described above. The floor plate fixture is not fixed to the floor plate by screw nails or the like, but only fixed to the support material. It is possible to regulate movement in any direction of the direction away from the support material 5, upward or surface direction of the floorboard, and the lengthwise direction of the floorboard. In addition to expansion and contraction in the width direction of the floor board, it can prevent damage to the floor plate fixture against expansion, contraction and warpage in the length direction, and further supports expansion and contraction as described above. However, an object of the present invention is to provide a floor plate fixing tool that can fix the floor plate to the support member without play, and thus can minimize the generation of noise during walking.

In order to achieve the above object, the floor board fixture 1 of the present invention is a floor board to which the floor board 4 in which slits 41 are continuously formed in the length direction is formed on each of the side surfaces 43 forming both ends in the width direction. In fixture 1,
For example, on the support material 5 arranged horizontally, the installation is carried out between the slits 41 by being inserted into both of the slits 41 formed in the side surfaces 43 of the floor plate 4 arranged adjacent to each other. A piece 3 and an intermediate piece 2 projecting in a direction perpendicular to the installation piece 3 from the center line in the length direction on the back surface 32 side of the installation piece 3 are made of thermoplastic resin such as ABS resin, polypropylene, polyethylene, chloride. It is integrally formed of a flexible synthetic resin material such as vinyl or nylon,
The provided with holes 31 for inserting the for example screw nails extending through the thickness of the bridging piece 3 in the center of the bridging piece 3, the intermediate piece on the back surface 32 side of the bridging piece 3 in the formation position of the holes 31 2 The projecting length H is made shorter (including H = 0) than the length h from the back surface 42 of the floor plate 4 to be fixed to the back side inner wall 41a of the slit 41,
Furthermore, deformation portions 22 and 23 are provided at both ends in the length direction of the intermediate piece 2 and at positions lower than the surface 33 of the installation piece 3 according to the change in the distance between the side surfaces 43 of the floor plate 4. And
On the back surface 32 of the erection piece 3, a peripheral thick part 34 is formed on the periphery thereof, and the erection piece side edge of the intermediate piece 2 on the one end 3 a side in the length direction of the erection piece 3. A first widthwise thick portion 35 formed on one end 3c side of the widthwise direction 3 and communicating with the peripheral thick portion 34;
The intermediate piece 2 on the other end side 3b in the length direction of the installation piece 3 is formed from the installation piece side edge of the intermediate piece 2 to the other end side 3d in the width direction of the installation piece 3 and communicates with the peripheral thick part 34. The second width-direction thick portion 36 is provided on the back surface of the installation piece 3 (Claim 1).

In the floor plate fixture 1 having the above-described configuration, the protruding length H of the intermediate piece 2 on the back surface 32 side of the installation piece 3 at the position where the hole 31 is formed is changed from the back surface 42 of the floor plate 4 to be fixed to the back side inner wall of the slit 41. In order to shorten the length h up to 41a,
Total height from the top lower edge until the rear surface 32 of the bridging piece 3 of the intermediate piece 2, be formed shorter from the floor plate rear surface 42 relative to the length h of up to the back surface side inner wall 41a of the slit 41 well (claim 2; see FIG. 7), or before the in the rear surface 32 side of the bridging piece 3 in the formation position of Kiana 31 to the intermediate piece 2, from the edge of the intermediate piece on the back side of the bridging piece 3 A notch 24 may be formed so that the protruding length H of the intermediate piece 2 from the installation piece 3 at this portion is zero or shorter than other portions (Claim 3; FIGS. 8 and 9). reference).

The deformable portions 22 and 23 may be formed in a cylindrical shape whose height direction is the length direction (Claim 4; see FIGS. 1 and 2), or both ends of the intermediate piece 2 are intermediate You may form in the planar view substantially V shape which branched and formed in the thickness direction of the piece 2 (Claim 5; refer to the example of a change in FIG. 2).

Further, the intermediate piece 2 is connected to the first and second widthwise thick portions 35 and 36 provided in the installation piece 3 from the installation piece side edge position to the opposite direction edge position of the intermediate piece 2. Thin wall portions 28a and 28b having a relatively thin wall thickness may be provided (see claim 6 , FIG. 2 and FIG. 5).

  With the configuration of the present invention described above, the floor board fixture 1 of the present invention has the following remarkable effects.

(1) The length H from the edge of the intermediate piece 2 to the back surface 32 of the installation piece 3 at the position where the hole 31 is formed is set to the length h between the back surface 42 of the floor plate 4 to be fixed and the back side inner wall 41a of the slit 41. On the other hand, by forming it short, the back surface 32 of the installation piece 3 can be strongly pressed against the back side inner wall 41a of the slit 41 by tightening the screw nails. By pressing and fixing the floor plate fixing tool 1 to the support material 5, the floor plate 4 is not fixed to the floor plate 4 with a screw nail or the like. It was possible to regulate movement in the direction of the length, as well as movement in the length direction.

  As described above, since the floor plate fixture 1 is not fixed to the floor plate 4 and is fixed only to the support material 5, the installation work of the floor plate 4 is relatively easy and the construction procedure is free. For example, it is easy to remove only one of the floorboards 4 attached to the center of the floor surface.

  Further, although the floor board fixture 1 is firmly pressed against the floor board 4, it is not fixed and the floor board fixture 1 is made of a flexible material. When an unnecessarily large force is applied due to expansion or contraction in the vertical direction, the floorboard fixture 1 allows the floorboard 4 to move in the length direction before breaking or the like, and the floorboard fixture 1 It was possible to prevent the peeling of the floor board due to the breakage of the floor.

  Moreover, in the floor board fixture 1 of the present invention, the size change accompanying such expansion in the length direction of the floor board 4 is not absorbed by play at the time of fixing, and the floor board 4 is not played on the support material 5 without play. Since it is pressed, it is possible to eliminate the occurrence of noise and the like caused by the collision between the floor board 4 and the floor board fixture 1 or the support material 5 when walking or the like when walking.

(2) Further, since it is formed of a flexible resin material and provided with the deformed portions 22 and 23, even if expansion and contraction occur in the width direction of the floor plate 4, the floor plate fixing tool Since not only the entire deformation but also the deformation portions 22 and 23 are crushed or recovered, it is possible to cope with a relatively large dimensional change.

(3) Further, since it is formed of a resin material having flexibility and is fixed at one position of the hole 31 provided in the central portion of the installation piece 3, the floor plate fixture 1 is centered on the hole 31. Both ends bend up and down, so that, for example, the installation piece 3 is disposed obliquely in the slit 41, so that not only the back side inner wall 41a but also the front side inner wall 41b of the slit 41 is brought into contact with or pressed to the floor plate 4 It was possible to more firmly regulate the movement in the length direction.

  Further, even when the floor plate 4 is warped in the length direction due to the deformation of the floor plate fixture 1, the floor plate fixture 1 is deformed following this and the floor plate fixture 1 is broken. It was possible to prevent this, and the state in which the floor plate 4 was fixed to the support material 5 could be maintained.

(4) Since the notch 24 is provided in the intermediate piece 2 on the back surface 32 side of the installation piece 3 at the position where the hole 31 is formed, the installation piece 3 of the floor plate fixture 1 is easily bent in the length direction around the position of the hole 31. Thus, the pressing force applied to the floor plate by tightening the screw nails can be increased, and the restriction on the movement of the floor plate 4 in the length direction can be more firmly performed.

  Further, even when the floor plate 4 is warped, the deformation of the floor plate 4 can be absorbed, and the floor plate fixture 1 is hardly broken.

(5) By forming the peripheral thick part 34 and the first and second widthwise thick parts 35 and 36 on the installation piece, the amount of resin material to be used is reduced while maintaining the strength of the floor board fixture 1. I was able to.

  Further, as a result of a difference in strength between the high-rigidity portion in which these thick portions 34, 35, and 36 are formed and the other portions, the installation piece 3 is slit into the floor plate 4 by tightening the screw nails. When pressed by the back side inner wall 41a in 41, the erection piece 3 is deformed and deformed differently between the high rigidity part and the low part, and this erection causes the erection piece 3 to become the bottom inner wall of the slit 41 of the floor plate 4 In addition to being pressed by 41a, the upper side 41b was also contacted and pressed to increase the force that restricts the movement of the floor plate 4 in the length direction.

(6) Particularly, the intermediate piece 2 is provided with thin portions 28a, 28b, and the thin portions 28a, 28b and the first and second width-direction thick portions 35, 36 of the installation piece 3 are continuous. In this case, the deformation of the erection piece 3 described above was further promoted, and the movement of the floor plate 4 in the length direction could be more effectively regulated.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

[Configuration of floor plate fixture]
The floor plate fixture 1 of the present invention is integrally formed of a synthetic resin material having appropriate rigidity and flexibility such as ABS resin, for example, and the adjacent floor plates 4 and 4 are opposed to each other. From the installation piece 3 inserted between the slits 41, 41 formed on the side surfaces 43, 43 to be installed between the slits 41, 41, and the longitudinal center line on the back surface 32 of the installation piece 3 An intermediate piece 2 that protrudes in a direction orthogonal to the installation piece 3 and is disposed between the side surfaces 43 and 43 of the adjacent floor plates 4 and 4 (see FIG. 7), and has an overall cross-sectional shape in the width direction. Are formed in a substantially T-shape (see FIG. 6).

  A hole 31 that penetrates the wall thickness of the installation piece 3 is formed in the central portion of the installation piece 3 (see FIGS. 1 to 3 and 6). The floor plate fixture 1 is configured to be mountable on the support member 5 by driving (screwing) the tip of the screw nail into the support member 5 formed of, for example.

  In the floor plate fixture 1 of the present embodiment in which the intermediate piece 2 protruding from the back surface 32 of the installation piece 3 is formed in a rectangular shape as a whole as shown in FIG. In the intermediate piece 2 provided on the back surface 32 side of the formation position, an opening 25 is formed that penetrates the thickness of the intermediate piece 2 in the height direction to extend the hole 31, and the tip of the screw nail inserted into the hole 31 is , The support member 5 can be reached through the opening 25.

  The height of the floor plate fixture 1 to the back surface of the installation piece 3, and hence the height of the intermediate piece 2, is determined from the back surface 42 of the floor plate 4 fixed by the floor plate fixture 1 to the inner wall 41 a on the back surface side of the slit 41. It is formed slightly shorter than the length h between them (see FIG. 7). In the floor plate fixture 1 of the present embodiment, the height of the entire intermediate piece 2 is shortened so that the holes 31 The length H from the back surface 32 of the installation piece 3 to the edge of the intermediate piece 2 at the formation position is shorter than the length h between the back surface 42 of the floor plate 4 and the inner wall 41a on the back surface side of the slit 41. Yes.

  When the height of the intermediate piece 2 is formed to be equal to or higher than the length h between the back surface 42 of the floor plate 4 and the inner wall 41a on the back surface side of the slit 41, the back surface 32 of the installation piece 3 is the back surface of the slit. At the same time as or in contact with the side inner wall 41a, the edge of the intermediate piece 2 comes into contact with the support member 5 and the movement of the floor plate fixture 1 in the direction of the back surface of the floor plate is restricted. Since the intermediate piece 2 has a predetermined short length, when the floor plate fixture 1 is fixed on the support member 5 with a screw nail through the hole 31, the back surface 32 of the installation piece 3 is the back side inner wall 41a of the slit 41. The screw nails can be further tightened even after coming into contact with each other, whereby the back surface 32 of the installation piece 3 is strongly pressed against the back side inner wall 41a of the slit 41 of the floor plate 4 so that the floor plate 4 is supported by the support material 5. It can be firmly pressed and fixed on top.

  Therefore, the movement of the floor plate 4 in the length direction is restricted without fixing the intermediate piece 2 to the side surface 43 in the length direction of the floor plate 4 with a screw nail or the like as in the floor plate fixture 1 described as the prior art. It is possible.

  At both ends in the length direction of the intermediate piece 2, deformed portions 22 and 23 are provided at positions lower than the surface 33 of the installation piece 3, and in the illustrated embodiment, the deformed portions 22 and 23 are provided as an example. The intermediate piece 2 is formed in a cylindrical shape in which the height direction is the length direction and the outer diameter is larger than the thickness of the other part of the intermediate piece 2.

  However, the shape of the deformed portions 22 and 23 is not limited to the cylindrical shape as described above. As an example, as shown as a modified example in FIG. 2, the thickness of the intermediate piece 2 is branched. It may be formed in a V shape in a plan view, and the interval between the side surfaces 43 and 43 of the floor plates 4 and 4 is caused by a dimensional change caused by the floor plates 4 and 4 expanding and contracting in the width direction, for example. The configuration is not limited as long as the deformable portions 22 and 23 are crushed or restored in accordance with the change to absorb the dimensional change.

  In the floor board fixture 1 described with reference to FIGS. 1 to 7, the projecting length of the intermediate piece 2 is shortened as a whole, whereby the back surface 32 of the installation piece 3 and the intermediate piece 2 at the position where the hole 31 is formed. The length H between the edges is shorter than the length h from the back surface 42 of the floor plate 4 to the bottom side inner wall 41a of the slit 41. Instead of this configuration, FIG. 8 and FIG. Thus, on the back surface side of the installation piece 3 at the position where the hole 31 is formed, a notch 24 is formed in the intermediate piece 2 from the edge side toward the installation piece 3, so By making the length H between the edges of the piece 2 zero (see FIG. 8), or by shortening the length H between the back surface 32 of the installation piece 3 and the edge of the intermediate piece 2 as compared with other parts. (See FIG. 9), the length H between the rear surface 32 of the installation piece 3 and the edge of the intermediate piece 2 at the position where the hole 31 is formed From the rear surface 42 up to the bottom side inner wall 41a of the slit 41 may be shorter than the length h.

  In the floor board fixture 1 of the present invention having a T shape in the cross-sectional shape in the width direction, when the rectangular intermediate piece 2 is provided as in the embodiment described with reference to FIGS. The installation piece 3 reinforced by 2 is less likely to warp or bend, but as described above, the intermediate piece 2 is not provided on the back side of the installation piece 3 at the position where the hole 31 is formed, or the intermediate piece 2 By providing the notch 24 in the lower part, the function of the intermediate piece 2 as a reinforcing member of the installation piece 3 is lowered, and the installation piece 3 is easily deformed around the hole 31, thereby supporting the floor plate 4 as described later. The ability to fix to the material 5 is enhanced.

  It should be noted that the installation piece 3 and the intermediate piece 2 of the floor plate fixture 1 are preferably formed with a thick part having a relatively large thickness and a thin part having a small thickness as shown in FIG. This reduces the amount of resin material used while maintaining the rigidity of the erection piece 3, tightens the screw nails to press the erection piece 3 against the bottom inner wall 41 a of the slit 41 of the floor plate 4, When the end edge portion 2 is pressed onto the support member 5, the construction piece 3 and the intermediate piece 2 are configured to have a desired distortion.

  In the present embodiment, in order to cause such distortion, the thickness of the peripheral portion on the back surface 32 of the installation piece 3 is relatively increased to form the peripheral thick portion 34, and the installation piece 3 A first thick portion in the width direction which is formed from one end 3a side in the length direction of the intermediate piece 2 to one end 3c side in the width direction of the installation piece 3 and communicates with the peripheral thick portion 34 35 and the other end 3b of the installation piece 3 in the length direction from the end of the intermediate piece 2 to the other end 3d in the width direction of the installation piece 3 and communicated with the peripheral thick part 34 A second widthwise thick portion 36 is provided.

  Further, a thin portion 28a having a relatively thin thickness in the height direction is formed on the intermediate piece 2 corresponding to the formation position of the first and second width-direction thick portions 35, 36 formed on the installation piece 3. , 28b are formed so that the distortion of the installation piece 3 is further promoted.

  In the embodiment shown in FIGS. 2 and 5, the thick end portions 26 a and 26 b are formed on both ends of the intermediate piece 2 in the length direction, and the central thick portion 27 is formed in the center portion in the length direction. And the above-mentioned thin portions 28a and 28b are formed by relatively thinning the thickness of the intermediate piece 2 between the two end thick portions 26a and 26b and the central thick portion 27. , 28b and the first and second width-direction thick portions 35, 36 described above are continuously formed.

[Usage and action]
The floor plate fixture 1 of the present invention configured as described above is installed between adjacent side surfaces of the floor plate 4 attached to the support member 5 in a state where the intermediate piece 2 faces downward. Both ends of the piece 3 are respectively inserted into the slits 41 formed on the side surfaces 43 of the floor plate 4, and arranged in a state of being laid between the slits 41.

  At this time, in the floor plate fixture 1 described with reference to FIGS. 1 to 7, the length H from the edge of the intermediate piece 2 to the back surface 32 of the installation piece 3 is from the back surface 42 of the floor plate 4 to be fixed to the slit 41. Since it is formed slightly shorter than the length h up to the back side inner wall 41a, the edge of the intermediate piece 2 is slightly separated from the support material 5 and is in a floating state (see FIG. 7).

  In such an arrangement state of the floor plate fixture 1, a screw nail or the like is inserted into the hole 31 formed in the central portion of the installation piece 3 and the tip thereof is screwed into the support member 5.

  As described above, since the edge of the intermediate piece 2 floats away from the support member 5, it is tightened until the head of the screw nail is accommodated in the slot 31 a formed in the hole 31. However, the end edge of the intermediate piece 2 does not reach the support member 5, and the movement of the floor plate fixture 1 in the direction of the back surface of the floor plate (downward in the figure) is not restricted.

  As a result, when the screw nail is further tightened from this state, the floor plate fixing tool 1 tries to move further toward the back surface of the floor plate while bending the construction piece 3. The force with which the back surface 32 presses the back side inner wall 41a of the slit 41 can be increased.

  As a result, while the floor plate fixture 1 is not fixed to the floor plate 4, not only the movement of the floor plate 4 in the direction away from the support member 5 but also the movement in the length direction can be firmly regulated. it can.

  In the configuration in which the notch 24 is provided on the back surface 32 side of the installation piece 3 at the position where the hole 31 is formed (see FIGS. 8 and 9), the edge of the intermediate piece 2 is placed on the support member 5 by tightening the screw nails. Even after the contact, the edge of the intermediate piece opens to the left and right of the page around the notch 24 by further tightening the screw nail, and the installation piece 3 is in the direction of the back of the floor board around the position where the hole 31 is formed (see FIG. The screw nails can be further tightened by deformation so as to bulge (downward) (see FIGS. 10A and 10B), whereby the floor plate 4 can be attached to the support material 5 with a stronger pressing force. It can be pressed against.

  In addition, when the floor plate fixture 1 is deformed in this manner, the installation piece 3 is arranged at an angle with respect to the length direction of the slit 41 (see FIG. 10B), and the installation piece 3 is positioned near the hole 31. 3 is not only pressed against the inner wall 41 a on the rear surface side of the slit 41, but also the surfaces 33 on both ends in the length direction of the installation piece 3 are pressed against the inner wall 41 b on the surface side of the slit 41 [ The portion marked with x in FIG. 10 (B)], the movement of the floor plate 4 in the length direction is more firmly regulated.

  In the structure shown in FIGS. 2 and 5 in which the thick portions 34, 35, and 36 (thin portions) are formed in the construction piece 3 in the pattern as described above, the thick portions 34, 35, and 36 are installed in the thick portions 34, 35, and 36. The rigidity of the piece 3 is high, and the erection piece 3 is easily deformed in the thin portion.

  And the formation direction of the 1st width direction thick part 35 in the length direction one end 3a side of the installation piece 3 and the 2nd width direction thick part provided in the other end 3b side in the length direction of the installation piece 3 36 is formed in the opposite direction in the width direction, so that the installation piece 3 of the floor plate fixture 1 thus configured is inserted into the slit 41 of the floor plate 4 and screw nails are tightened. When the back surface 32 of the installation piece 3 is pressed against the inner wall 41a of the back surface of the slit with a strong force, the installation piece 3 is distorted so as to be twisted as a whole about the center line in the length direction.

  As a result, not only the back surface 32 of the installation piece 3 is pressed against the inner wall 41a of the rear surface of the slit but also the surface 33 of the installation piece 3 is pressed and brought into contact with the inner wall 41b of the front surface of the slit 41 due to this distortion. In addition, the movement of the floor plate 4 in the length direction is restricted.

  Moreover, when the thin portions 28a and 28b having the above-described pattern are formed on the intermediate piece 2, the intermediate piece 2 is more likely to be deformed at the thin portions 28a and 28b, so that such distortion of the installation piece 3 is further increased. Assisted, the restriction on the movement of the floor plate 4 in the length direction is more firmly performed.

  When the floor plate 4 is attached, the intermediate piece 2 of the floor plate fixture 1 is sandwiched between the adjacent floor plates 4, so that the thickness of the intermediate piece 2 between the adjacent floor plates 4, particularly the deformed portion 22, An interval defined by a thickness of 23 is provided.

  As described above, when the floor board fixture 1 of the present invention is attached at intervals of about 600 mm as an example in the length direction of the floor board 4, and the necessary number of floor boards 4 are attached to the floor surface, the floor board of the present invention is obtained. When the floor plate 4 fixed by the fixture 1 is deformed such as expansion or contraction due to changes in temperature or humidity, for example, such deformation occurs in the width direction of the floor plate 4. The dimensional change due to this deformation is absorbed by the deformation of the floor plate fixture 1 as a whole, and is also absorbed by the above-described deformation portions 22 and 23 being crushed or restored.

  Further, as described above, the floor plate fixture 1 is not “fixed” to the floor plate 4 by screw nails or the like, but is in a state where the back surface 32 side of the installation piece 3 is strongly “pressed” by the back surface inner wall 41 a of the slit 41. However, it does not move on the floor plate 4 by the force of walking or running on the floor plate 4, but the floor plate is moved in the length direction by expansion or contraction due to heat or humidity. When a strong force to be moved is generated, the floor plate is allowed to move in the length direction in combination with the elastic deformation of the floor plate fixture 1.

  Therefore, by allowing the movement of the floor plate 4 in the length direction in this way, the floor plate fixture 1 is not damaged by the expansion and contraction of the floor plate 4 in the length direction. 4 attachment state can be maintained.

  Further, even when the floor plate 4 is warped or distorted in the length direction, the floor plate fixture 1 can be prevented from being deformed in the length direction and being damaged.

  In addition, since the floor plate 4 is attached to the support material 5 without play, the floor plate 4 collides with the floor plate fixture 1 and the support material 5 due to play when walking on the floor plate 4. It is possible to reduce noise caused by the above.
