Description

  The present invention relates to a corrugated board installation structure and a building in which corrugated boards are installed on a wall portion of a house or the like.

  In houses, etc., there is a staircase that connects the downstairs and the upstairs. As the staircase structure, a pair of left and right side plates (saddle girders) provided at a predetermined interval and a wall are fixed with support brackets. A structure in which step plates are installed in multiple stages on a metal fitting is known (see, for example, Patent Document 1). Specifically, as shown in FIG. 10A, a support fitting 71 having an L-shaped cross section is fixed to a wall portion W at a stair installation place, and a step plate 70 is installed on the support fitting 71. In this case, the wall W and the support metal 71 are fixed by the fixing screw 72, and the step plate 70 and the support metal 71 are fixed by the fixing screw 73.

  However, the above-described structure has a problem that the workability of installing the corrugated board is poor. In other words, the screw tightening operation is usually performed using a tightening device such as an electric screwdriver at the time of installing the corrugated board. For example, the distance between the corrugated board 70 and the floor surface F (A dimension in the figure) is at the lowermost stage. Since it is relatively narrow, the screw tightening operation cannot be performed with the tightening device such as an electric screwdriver facing upward. Therefore, the tightening operation of the fixing screw 73 for fixing the step plate 70 and the support fitting 71 becomes extremely difficult.

  On the other hand, as shown in FIG. 10B, a support fitting 81 having an L-shaped cross section is fixed to the wall W by a fixing screw 82, and a flat support fitting 83 is fixed to the lower surface of the step plate 70. A structure in which the two support fittings 81 and 83 are connected by a fixing screw 85 using a gap between the wall portion W and the side surface of the step plate 70 is conceivable. In such a structure, the final screw tightening operation at the time of installing the corrugated plate is performed on the fixing screw 85, and the operation can be performed from above using a tightening device such as an electric screwdriver. Therefore, the problem of deterioration in workability as described with reference to FIG.

However, in the case of FIG. 10B, the workability can be improved, but the fixing screw 85 can be seen through the gap between the wall portion W and the side surface of the step plate 70 after the step plate is installed. Therefore, there arises a problem that the configuration is not desirable in terms of appearance.
JP 2005-273193 A

  The main object of the present invention is to provide a corrugated board installation structure and a building that can improve workability at the time of corrugated board installation and can suppress deterioration in quality after the corrugated board is installed. is there.

  Hereinafter, means and the like effective for solving the above-described problems will be described while showing functions and effects as necessary. In the following, in order to facilitate understanding, a corresponding configuration example in the embodiment of the invention is appropriately shown in parentheses, etc., but is not limited to the specific configuration shown in parentheses.

The present invention relates to a step plate installation structure for installing a step plate (step plate 10) on a wall portion (wall portion W) of a house or the like. As a feature thereof, a base metal fitting (base metal fitting 21) fixed to the wall part in a standing state from the wall part, and an elastic deformation part (elastic deformation) connected to a position away from the wall part and extending upward in the base metal fitting. And a stepping plate supporting member (supporting hardware 20) including a connecting fitting (coupling fitting 22) having a portion 22c). And the coupling metal fitting of the corrugated board support member was inserted in the hole part (joining hole 11) of the predetermined depth formed in the lower surface side of the corrugated board in the state elastically deformed. When placing the step plate on the step plate support member, the step plate may be placed on the base metal fitting.

  According to the above configuration, when the step plate is placed on the step plate support member, the coupling fitting is inserted into the hole portion of the step plate, and at that time, the coupling fitting is elastically deformed so that the step plate and the step plate support member are The coupling and the position fixing of the corrugated plate are performed. In this case, after placing the step plate on the step plate support member, an operation such as screw tightening from the lower surface side of the step plate becomes unnecessary. Therefore, it is possible to avoid that the installation work becomes difficult even when the lower space of the step board is small when installing the lowermost step board. In this case, a fastening member such as a screw is not seen from above, and deterioration of appearance is suppressed. As described above, the workability at the time of installing the corrugated board can be improved, and the deterioration of the quality in appearance after the corrugated board can be installed can be suppressed.

  In this specification and the like, “step board” is not limited to plate members installed in multiple stages to install stairs, and includes those installed in about one or two stages. It can also be called a “treadboard”.

  In the elastically deforming portion of the coupling fitting, it is preferable to attach a vibration isolating member (vibration isolating rubber 23) to the contact portion with the inner wall of the hole formed in the corrugated plate. In this case, it is possible to prevent the position deviation of the step plate and the like by the vibration isolation member. Moreover, the noise which arises between a step board and a coupling metal fitting can be prevented.

  Further, it is preferable that the elastically deforming portion of the fitting is folded downward and formed at a predetermined interval, and the fitting is inserted into the hole portion of the corrugated plate in a state accompanied by deformation of the folded portion. In this case, the connection between the step plate and the step plate support member can be made stronger by deformation of the folded portion of the elastic deformation portion.

  Here, a metal plate (metal plate 30) for closing a part of the opening of the hole is attached to the lower surface of the step plate, and the folded tip end portion of the elastically deforming portion is engaged at the opening closing portion by the metal plate. It is good to stop, and this can prevent the step board from falling off.

  On the other hand, in 2nd invention, it is fixed to this wall part in the state which stood up from wall parts (wall part W), such as a house, and is a joint part (joint part 40c) extended upwards in the position away from the said wall part. And a space (space part SP) into which the support metal fitting is inserted and a hole (joint hole 11) having a predetermined depth formed on the lower surface side of the step plate. ) Forming an elastic deformation member (elastic block 45). The step plate is placed on the support fitting, and the coupling portion of the support fitting is inserted into the space portion in a state where the elastic deformation member is elastically deformed.

  According to the above configuration, when the step plate is placed on the support fitting, the connecting portion of the support fitting is inserted into the space formed by the elastic deformation member in the hole of the step plate, and the elastic deformation member is By elastically deforming, the step plate and the support metal are coupled and the position of the step plate is fixed. In this case, after the step plate is placed on the support metal fitting, an operation such as screw tightening from the lower surface side of the step plate becomes unnecessary. Therefore, it is possible to avoid that the installation work becomes difficult even when the lower space of the step board is small when installing the lowermost step board. In this case, a fastening member such as a screw is not seen from above, and deterioration of appearance is suppressed. As described above, the workability at the time of installing the corrugated board can be improved, and the deterioration of the quality in appearance after the corrugated board can be installed can be suppressed.

  Here, the elastic deformable member is constituted by two pieces of separable elastic bodies (elastic bodies 46 and 47), and a tapered space portion is formed between the two pieces of elastic bodies. It is preferable to insert the connecting portion of the support fitting. In this case, since the space portion is formed in a tapered shape, the insertion work is facilitated when the coupling portion of the support metal fitting is inserted into the space portion.

  In the step board installation structure, a gap (gap SA) may be provided between the wall portion and the side surface of the step board. In this case, the problem that dust, dirt, or the like accumulates in the corner portion formed by the wall portion and the step plate due to the gap between the wall portion and the side surface of the step plate is solved. It is also possible to improve the appearance.

  And the provision of a suitable building is attained by employ | adopting the stairs constructed using said step board installation structure for buildings, such as a house.

[First Embodiment]
Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, left and right wall portions W are provided at predetermined intervals in a stairs installation place in a house, and a plurality of step plates 10 are fixed in steps so as to connect the left and right wall portions W. Has been. In the present embodiment, the corrugated plate 10 is configured to be individually fixed to the left and right wall portions W.

  Next, the installation structure of the corrugated board 10 is demonstrated using FIG. 2 is a cross-sectional view of a main part showing a state in which the step plate 10 is installed on the support metal 20 fixed to the wall W. FIG. 3 is a perspective view showing a state in which the support metal 20 is fixed to the wall W. FIG. FIG. 5 is an exploded perspective view showing components of the support hardware 20 in an exploded manner, FIG. 5 is a perspective view of the step plate 10 as viewed from the lower surface side, and FIG. 6 is a view for explaining an installation procedure of the step plate 10.

  A coupling hole 11 is formed on the lower surface side of the step plate 10 so as to open downward and have a rectangular opening. A plurality of coupling holes 11 are formed in the vicinity of the left and right ends of the step plate 10 (for example, two locations), and the step plate 10 is fixed by inserting the support hardware 20 into each coupling hole 11. It has become. The plurality of coupling holes 11 in the vicinity of both left and right ends are formed side by side in the front-rear direction.

  Further, a metal plate 30 having two holes 31 corresponding to the coupling holes 11 is joined to the lower surface of the step plate 10. In the metal plate 30, the opening of the hole 31 is slightly smaller than the coupling hole 11. As shown in FIG. 2, the opening of the coupling hole 11 is performed when the metal plate 30 is joined to the lower surface of the step plate 10. A part of the metal plate 30 is blocked by the metal plate 30.

  The support hardware 20 includes a base fitting 21 fixed to the wall W while standing from the wall W, a coupling bracket 22 coupled to the base bracket 21 at a position away from the wall W, and a coupling bracket. The anti-vibration rubber 23 is attached to the upper portion of 22. The base metal fitting 21 is made of a metal material having relatively high rigidity, and is bent into a crank shape. In the base metal member 21, through holes 21 b are formed in two upper and lower portions in the wall fixing portion 21 a that is the base end portion, and screws 25 are inserted into the through holes 21 b to fix the base metal member 21 to the wall portion W. It has become so. Further, in the base metal member 21, through holes 21 d are formed at two left and right portions in the connecting plate part 21 c that is a connecting part with the connecting metal member 22.

On the other hand, the coupling fitting 22 is made of a highly elastic metal material, and through holes 22b are provided at two right and left portions in the joint fixing portion 22a so as to correspond to the through holes 21d on the base fitting 21 side. The base metal 21 and the coupling metal 22 are integrated by inserting a screw 26 into the through holes 21d and 22b in a state where the connecting plate portion 21c of the base metal 21 and the joint fixing part 22a of the coupling metal 22 are overlapped. It is like that. In the coupling fitting 22, an upper part of the joint fixing part 22a is an elastic deformation part 22c, and the elastic deformation part 22c extends upward from the joint fixing part 22a as shown in the drawing and is folded downward at a predetermined interval. Are molded.

  The anti-vibration rubber 23 is made of an elastic sheet plate having substantially the same length as the elastic deformation portion 22c of the coupling fitting 22, and is provided so as to cover the elastic deformation portion 22c. At this time, the anti-vibration rubber 23 is bonded to the elastic deformation portion 22c by an adhesive means such as an adhesive or a double-sided tape.

  In a state in which the step plate 10 is installed on the support hardware 20, a gap SA is provided between the wall W and the side surface of the step plate 10 as shown in FIG. 2. In this case, the problem that dust, dust, etc. accumulate in the corner part which consists of wall part W and step board 10 by gap SA is solved. It is also possible to improve the appearance. Specifically, when the length dimension from the side surface to the coupling hole 11 in the step plate 10 is L1, and the length dimension in the standing direction of the support hardware 20 with respect to the wall W is L2, L1 <L2. A gap SA is formed between the wall W and the side surface of the step plate 10. At this time, the width dimension of the gap SA is, for example, about 3 to 4 cm.

  When constructing a staircase in a house or the like, as shown in FIG. 6 (a), first, a support hardware 20 is prepared by integrating a base metal fitting 21 and a coupling metal fitting 22 with screws 26, and the support hardware 20 is attached. It is fixed at a predetermined position on the wall W with a screw 25. At this time, two left and right support hardwares 20 are attached and fixed to one step plate 10 in accordance with the position of the coupling hole 11 of the step plate 10. Next, a step plate 10 in which a metal plate 30 is bonded to the lower surface in advance is prepared, and the step plate 10 is set on the support metal 20.

  At this time, as shown in FIG. 6B, the coupling fitting 22 (elastically deforming portion 22c) of the support metal 20 is inserted into each coupling hole 11 of the step plate 10, and the elastically deforming portion 22c is elastically deformed accordingly. . Then, when the lower surface of the step plate 10 (in particular, the metal plate 30 in the present embodiment) comes into contact with the base metal fitting 21, the installation of the step plate 10 is completed. FIG. 2 shows the installation completion state of the corrugated board 10. In the installation completion state, since the coupling fitting 22 (elastically deforming portion 22c) is held in an elastically deformed state, the anti-vibration rubber 23 adhered to the outer peripheral side of the coupling fitting 22 (elastically deforming portion 22c) Pressed against the inner wall. At this time, the step plate 10 and the support hardware 20 are coupled and the position of the step plate 10 is fixed by the elastic deformation of the elastic deformation portion 22c and the vibration isolation action of the vibration isolation rubber 23.

  Further, in the installation completion state, the folded tip end portion of the elastic deformation portion 22 c is locked to the opening closing portion of the metal plate 30. Thereby, the dropout of the corrugated board 10 is prevented.

  According to the step plate installation structure of the present embodiment described in detail above, after the step plate 10 is placed on the support metal 20, work such as screw tightening from the lower surface side of the step plate 10 becomes unnecessary. Therefore, it is possible to prevent the installation work from becoming difficult even when the lower space of the step board 10 is small, for example, when the lowermost step board 10 is installed. That is, it can be said that this installation structure is a particularly suitable installation structure when the lowermost step plate 10 is installed. Further, in this case, a fastening member such as a screw is not seen from above through the gap SA or the like, and appearance deterioration is suppressed. As described above, the workability at the time of installing the corrugated board can be improved, and the deterioration of the quality in appearance after the corrugated board can be installed can be suppressed.

Since the anti-vibration rubber 23 is attached to the contact portion of the elastic deformation portion 22c of the coupling metal 22 with the inner wall of the coupling hole 11 of the step plate 10, the position of the step plate 10 and the generation of noise are prevented by the anti-vibration action. be able to.

  In addition, the elastic deforming portion 22c of the connecting metal fitting 22 is folded back and formed, and the connecting metal fitting 22 (elastically deforming portion 22c) is inserted into the connecting hole 11 of the corrugated plate 10 with deformation of the folded portion. The connection between the step plate 10 and the support hardware 20 can be made stronger.

[Second Embodiment]
Next, a second embodiment will be described. FIG. 7 is a cross-sectional view of the main part showing a state in which the step plate 10 is installed on the support fitting 40 fixed to the wall W. FIG. 8 is a perspective view showing the elastic block 45 assembled in the coupling hole 11 of the step plate 10. 9 is a view for explaining the installation procedure of the corrugated board 10.

  The support fitting 40 is a fitting member that is fixed to the wall portion W while standing up from the wall portion W, and is bent in a crank shape from a relatively rigid metal material. In the support fitting 40, through holes 40b are formed at two upper and lower portions in the wall fixing portion 40a which is the base end portion, and screws 42 are inserted into the through holes 40b to fix the support fitting 40 to the wall portion W. It has become so. Further, a portion parallel to the wall portion W is formed at a position away from the wall portion W in the support metal fitting 40, and the portion is a coupling portion 40c coupled to the step plate 10 side.

  The elastic block 45 is composed of two pieces of elastic bodies 46 and 47 having the same shape, and the inner surface portions 46a and 47a facing each other are tapered. In this case, a tapered space portion SP is formed between the elastic bodies 46 and 47 by joining the elastic bodies 46 and 47 together. The area of the upper surface portion of the elastic block 45 is substantially equal to the opening area of the coupling hole 11 of the step plate 10, and the height dimension of the elastic block 45 is equal to the depth dimension of the coupling hole 11. The elastic block 45 is bonded to the coupling hole 11 of the step plate 10 by an adhesive means such as an adhesive or a double-sided tape.

  When constructing a staircase in a house or the like, as shown in FIG. 9A, first, the support fitting 40 is fixed to a predetermined position on the wall W with a screw 42. At this time, two left and right support fittings 40 are attached and fixed to one step plate 10 in accordance with the position of the coupling hole 11 of the step plate 10. Next, the step plate 10 in which the elastic block 45 is mounted in the coupling hole 11 is prepared, and the step plate 10 is installed on the support fitting 40.

  At this time, as shown in FIG. 9B, the coupling portion 40c of the support fitting 40 is inserted into the space SP of the elastic block 45, and the elastic block 45 is elastically deformed accordingly. Then, when the lower surface of the step plate 10 comes into contact with the support fitting 40, the installation of the step plate 10 is completed. Here, since space part SP is formed in the taper shape, when inserting the coupling | bond part 40c of the support metal fitting 40 in this space part SP, the insertion operation | work becomes easy. FIG. 7 shows the installation completion state of the corrugated board 10. In the installation completed state, the coupling portion 40c of the support metal fitting 40 is held in a state where the elastic block 45 is elastically deformed, whereby the step plate 10 and the support metal fitting 40 are securely coupled, and the position of the step plate 10 is determined. Deviation is prevented.

  As described above, according to the second embodiment, after the step plate 10 is placed on the support metal fitting 40, work such as screw tightening from the lower surface side of the step plate 10 becomes unnecessary. Therefore, similarly to the first embodiment, it is possible to avoid that the installation work becomes difficult even when the lower space of the step plate 10 is small when the lower step plate 10 is installed. . Further, in this case, a fastening member such as a screw is not seen from above through the gap SA or the like, and appearance deterioration is suppressed. As described above, the workability at the time of installing the corrugated board can be improved, and the deterioration of the quality in appearance after the corrugated board can be installed can be suppressed.

  In addition, this invention is not limited to the content of description of the said embodiment, For example, you may implement as follows.

  In the first embodiment, the base metal fitting 21 is bent and formed in a crank shape, and the connecting metal fitting 22 is connected to the connecting plate portion 21c parallel to the wall portion W (see FIG. 4 and the like), but this is changed. . For example, the base metal fitting 21 is L-shaped, and has a wall fixing portion that is a base end portion, and an upright portion that stands upright from the wall fixing portion. And it is good also as a structure which connects the coupling metal fitting 22 to the standing part (part perpendicular | vertical with respect to the wall part W).

  In the first embodiment, the support hardware 20 is constituted by one base metal fitting 21 and one joint metal fitting 22, but this is changed and two base metal fittings 21 are combined with two base metal fittings 21. The support hardware 20 may be configured. That is, a base metal fitting is formed in a horizontally long shape, and two support hardwares are attached to the base metal fitting. In this case, the number of support hardware attached to the base metal fitting is not limited to two, and any support metal attachment may be used in a broad sense. With the above configuration, it is possible to facilitate the work of attaching the support hardware to the wall portion W. Also with respect to the second embodiment, it is possible to share the support bracket 40 with respect to the plurality of coupling holes 11 of the step plate 10.

  In the first embodiment, the metal plate 30 having the two hole portions 31 corresponding to the coupling holes 11 is joined to the lower surface of the stepped plate 10, but the main purpose of providing the metal plate 30 is that of the coupling holes 11. For this purpose, the metal plate 30 does not necessarily have the hole 31.

  In the second embodiment, the elastic block 45 is constituted by the two pieces of elastic bodies 46 and 47 which can be separated. However, it is also possible to change this and form an integral elastic body. For example, the joining portion of the two pieces of elastic bodies 46 and 47 in the above configuration is integrated so that the separation is impossible. In addition, a concave portion (actually a concave portion slightly smaller than the coupling portion 40c) is formed in the block piece having a rectangular parallelepiped shape as a whole in accordance with the size of the coupling portion 40c of the support bracket 40. And it is set as the structure which forms a taper-shaped space part in the recessed part, and inserts a support metal fitting in the space part.

  In each of the above embodiments, the gap SA is provided between the wall portion W and the side surface of the stepped plate 10, but the gap SA is arbitrary and may have a structure without the gap SA.

  In each said embodiment, although the implementation example about the case where a staircase is constructed by installing the several step board 10 in steps was demonstrated, the step board installation structure of this invention can also be applied to others. . For example, the present invention can be applied as an installation structure such as a footboard (rising fence) attached to a stepped portion of a rising entrance such as a house entrance or a self-explanatory door.
