Description

Support structure of wall panel and standing support method of wall panel

INDUSTRIAL APPLICABILITY The present invention relates to a wall panel support structure for supporting a plurality of wall panels in an upright position on a guide rail along a floor surface and an upright support for the wall panels in a construction in which a plurality of wall panels are connected to construct an inner wall. Regarding the method.

At the construction site where the inner wall of a bathroom or living room is constructed, a large number of wall panels mass-produced at the factory are supported in an upright position on a guide rail along the floor FL, and adjacent to each other aligned along the guide rail. The inner wall is constructed by connecting the wall panels. When constructing this inner wall, if the guide rails are not arranged horizontally along the floor FL due to the unevenness of the floor FL, the plurality of wall panels supported by the guide rails are also inclined and supported. The position of the upper end of each wall panel is different, there is a gap between it and the ceiling surface, and the upright support bracket fixed to the skeleton cannot be connected to the upper part of the wall panel, and the wall panel is placed along the vertical surface. In some cases, it was not possible to support standing up.

Therefore, conventionally, a height adjusting bracket for adjusting the height of the guide rail on the floor surface is placed between the wall panel and the guide rail, and the wall panel is placed on the guide rail horizontally arranged along the floor surface FL. A support structure for a wall panel that supports in an upright position is known (Patent Document 1).

Hereinafter, the support structure 100 of the wall panel described in Patent Document 1 will be described with reference to FIGS. 9 and 10. In the figure, 101 is a wall panel that is uprightly supported on the guide rail 102 by the support structure 100 of the wall panel, and a U-shaped fitting frame 103 having a downward cross section is fixed along the lower end of the wall panel 101. A nut 107 is fixed to the flat surface of the fitting frame 103 by welding, and a panel adjusting bolt 106 whose male thread portion inserts the fitting frame 103 and is screwed into the nut 107 is screwed to the fitting frame 103 with the head as the lower end. It has been stopped.

Further, the guide rail 102 includes a gutter-shaped runner member 102A fixed to the floor surface FL with anchor bolts 104, a rail 102B fitted inside the runner member 102A from above the runner member 102A, and a height adjusting bracket 105. It is composed of a U-shaped horizontal adjusting metal fitting 102C having a downward cross section, which is arranged on the rail 102B via the rail 102B and is fitted onto the runner member 102A.

The height adjusting bracket 105 is composed of height adjusting bolts in which the head abuts on the inner top surface of the horizontal adjusting bracket 102C and the male screw is screwed into the rail 102B, and the rail 102B is formed along the longitudinal direction of the guide rail 102. Height adjusting bolts 105 having the same structure are screwed into a plurality of positions of the above. The height adjusting metal fitting 105 adjusts the plane of the horizontal adjusting metal fitting 102C to a horizontal plane even if the floor surface FL is uneven. That is, before the leveling metal fitting 102C is fitted onto the runner member 102A from above, each height is adjusted so that the heads of the plurality of height adjusting bolts 105 screwed into the rail 102B belong to the same horizontal plane. The horizontal adjustment metal fitting 102C is placed on the height adjustment bolt 105 in which the head is aligned on the same horizontal plane by rotating the bolt 105, and the flat surface of the horizontal adjustment metal fitting 102C is horizontal regardless of the unevenness of the floor surface FL. Adjust so that

The wall panel 101 is guided by a fitting frame 103 fixed along the lower end thereof, which is fitted onto the horizontal adjustment metal fitting 102C and is arranged on the horizontal adjustment metal fitting 102C via the panel adjustment bolt 106. It is supported in an upright position on the rail 102. Therefore, if the lengths of the panel adjusting bolts 106 protruding downward from the fitting frame 103 are the same, each wall panel 101 arranged on the horizontal adjusting metal fitting 102C adjusted along the horizontal plane is placed along the horizontal plane. Can be supported at the same height. Further, the height of each wall panel 101 can be adjusted by adjusting the amount of screwing of each panel adjusting bolt 106 to the nut 107.

Further, apart from the conventional wall panel support structure 100, a height adjusting metal fitting for adjusting the guide rail so as to be arranged along a horizontal plane is provided as a first vertical plate having an elongated hole in the vertical direction. A first angle plate composed of a first horizontal plate that supports the guide rail, a second vertical plate having an elongated hole in the vertical direction, and a second horizontal plate arranged along the floor surface FL. The first vertical plate and the second vertical are stacked along the vertical plane between the second angle plate, the tightening bolts inserted into the elongated holes of the first vertical plate and the second vertical plate, and the tightening bolts. It consists of a tightening nut that holds the plate, and the positions of the long holes of the first vertical plate and the second vertical plate through which the tightening bolt is inserted are changed to adjust the distance between the first horizontal plate and the second horizontal plate. 1 The height of the guide rail supported by the horizontal plate on the floor FL can also be adjusted.

Jikkenhei 4-63706 Gazette

However, in the work of adjusting the guide rail 102 (horizontal adjustment metal fitting 102C) to be supported on the floor surface FL along the horizontal plane by the support structure 100 of the wall panel, the heads of the plurality of height adjusting bolts 105 are placed on the same horizontal plane. After arranging along the above, the horizontal adjustment metal fitting 102C is placed on the head of the height adjustment bolt 105, so that the adjustment work is complicated and if the horizontal adjustment metal fitting 102C itself is deformed, the horizontal adjustment is performed. The flat surface of the metal fitting 102C is not horizontal.

If an opening for performing the rotation adjustment operation of the height adjustment bolt 105 is formed on the side surface of the horizontal adjustment metal fitting 102C, the horizontal adjustment is performed while the horizontal adjustment metal fitting 102C is placed on the heads of the plurality of height adjustment bolts 105. Although it is possible to adjust the metal fitting 102C horizontally, it is still necessary to rotate and adjust the head of the height adjustment bolt 105, which is adjusted by advancing and retreating in the vertical direction, from the side through the opening. The adjustment work was complicated.

On the other hand, if a height adjustment bracket composed of a set of angle plates is used, the first vertical plate and the second vertical plate are laterally (laterally) to the side of the set of angle plates in which the first vertical plate and the second vertical plate are stacked along the vertical plane. Since the head of the tightening bolt that adjusts by advancing and retreating in the direction parallel to the floor surface protrudes, the rotation adjustment operation of the tightening bolt can be easily performed. However, since the guide rail is supported only by the frictional force between the first vertical plate and the second vertical plate sandwiched between the tightening bolt and the tightening nut, the weight of the wall panel to which the ceramic tile plate is attached is heavy. When the wall panel was supported by the guide rail, the insertion position of the long hole of the tightening bolt was gradually lowered, and there was a risk that the guide rail would be tilted with respect to the horizontal plane.

Further, both the height adjusting bracket (height adjusting bolt) 105 of the support structure 100 of the wall panel and the height adjusting bracket using a set of angle plates are arranged below the guide rail that supports the wall panel. Therefore, since the appearance of the room is spoiled as it is, in the support structure 100 of the wall panel, the substrate 101a of the wall panel 101 is hung near the lower side of the guide rail 102, and the height adjusting metal fitting 105 is covered with the substrate 101a.

Hereinafter, the support structure 1 of the wall panel according to the embodiment of the present invention will be described with reference to FIGS. 1 to 8. The wall panel support structure 1 according to the present embodiment is on the guide rail 4 along the horizontal plane on the floor FL in the construction in which a plurality of wall panels 2, 2, ... Are connected to form the inner wall 10 in the building. In addition, in order to support a plurality of wall panels 2, 2 ... It is a structure that aligns along. In the following description of each part in the present embodiment, the vertical direction in the state where the wall panel 2 is erected is the vertical direction, the connection direction between the wall panels 2 and 2 shown in FIG. 2 is the horizontal direction, and FIG. The direction in which the ceramic tile plate 24 of the wall panel 2 illustrated in 1 is attached will be described as the front, and the direction of the frame 20 will be described as the rear.

As shown in FIGS. 1 to 3, the wall panel support structure 1 includes a plurality of wall panels 2, 2 ..., a guide rail 4 for supporting the plurality of wall panels 2, 2, ..., and a wall surface WA of the skeleton. A standing support metal fitting 5 that is connected to and supports the wall panel 2 supported on the guide rail 4 in an upright posture along a vertical surface, and a plurality of heights arranged between the floor surface FL and the guide rail 4. It is composed of an adjusting metal fitting 3 and a floor finishing layer M laid on the floor FL.

The guide rail 4 that supports the plurality of wall panels 2, 2, ... Is a base made of an aluminum alloy in which a pair of rails 41a and 41a parallel to each other in the longitudinal direction are integrally projected on the upper surface by die casting. It is composed of a runner 41 and an elongated strip-shaped flat bar 42 that is screwed and fixed along the lower surface of the base runner 41 to reinforce the base runner 41. The pair of rails 41a, 41a engage with the inner wall surface of the lowermost cross rail 22 described later of the wall panel 2, and serve as a guide portion for guiding the wall panels 2, 2, ... Along the linear guide rail 4. By acting, the plurality of wall panels 2, 2, ... Are guided by a pair of rails 41a, 41a, and are aligned and supported on the guide rail 4 on the same plane.

In order to arrange the guide rail 4 on the concrete floor FL along the horizontal plane, a plurality of height adjustments for adjusting the height of the guide rail 4 on the floor FL between the guide rail 4 and the floor FL. The metal fitting 3 is arranged. As shown in FIGS. 4 to 6, the height adjusting metal fitting 3 is formed by bending a rectangular rigid plate at a right angle by press molding, and the first angle plate 31 and the second angle plate 33 are vertically opposed to each other. It is composed of a tightening bolt 35 and a tightening nut 36 for tightening the first vertical plate 31a of the first angle plate 31 and the second vertical plate 33a of the second angle plate 33 which are stacked along the above.

The second horizontal plate 33b of the second angle plate 33 is arranged along the floor surface FL, and the second horizontal plate 33 is inserted by the anchor bolt 37 screwed into the concrete of the floor surface FL. It is fixed to the floor FL. Further, in the center of the second vertical plate 33a standing upward at the rear end of the second horizontal plate 33b in the left-right direction, a second elongated hole 34 having a longitudinal direction in the vertical direction is bored.

The first angle plate 31 is formed in the same shape as the second angle plate 33, and the first vertical plate 31a is rotated 180 degrees around the axis in the front-rear direction with respect to the second angle plate 33. It is superposed on the front surface of the second vertical plate 33a of the plate 33. As a result, the first elongated hole 32 formed in the center of the first vertical plate 31a in the left-right direction and having the vertical direction as the longitudinal direction communicates with the second elongated hole 34 in the front-rear direction and becomes the first elongated hole 32. The tightening bolt 35 can be freely inserted into the second elongated hole 34. Further, in this rotated posture, the first horizontal plate 31b of the first angle plate 31 faces the second horizontal plate 33b above the second horizontal plate 33b, and is guided by the upper surface thereof as shown in FIG. Supports rail 4.

Since a part of the first elongated hole 32 and the second elongated hole 34 communicate in the front-rear direction with the vertical direction as the longitudinal direction, the first horizontal plate 33b and the first horizontal plate 31b are inserted while the tightening bolt 35 is inserted. The spacing, i.e., the height that supports the guide rails 4 on the floor FL can be adjusted. Therefore, the tightening bolt 35 is screwed and rotated at a position where the distance between the second horizontal plate 33b and the first horizontal plate 31b is adjusted so that the guide rail 4 is arranged along the horizontal plane, and the tightening nut 36 and the tightening nut 36 are operated. The first vertical plate 31a and the second vertical plate 33a are tightened between them, and the first angle plate 31 is fixed to the second angle plate 33 fixed to the floor surface FL. In the screwing rotation operation of the tightening bolt 35, the tightening bolt 35 can be screwed and rotated from the front-rear direction with the guide rails 4 arranged along the horizontal plane on the plurality of height adjusting metal fittings 3. The height of each height adjusting metal fitting 3 can be easily adjusted.

Assuming that the guide rail 4 receives an evenly distributed load from the heavy wall panel 2, the plurality of height adjusting metal fittings 3 are connected here on the guide rail 4 so that a large bending moment does not occur in the guide rail 4. It is arranged between the connecting portion between the wall panels 2 and 2 and the guide rail 4 below the intermediate position of each wall panel 2 and the floor surface FL.

The plurality of wall panels 2, 2, ... Supported on the guide rail 4 are each formed of the same member and have the same shape, and each wall panel 2 is a vertical crosspiece 21 as shown in FIG. A rectangular contour frame 20 in which horizontal crosspieces 22 in the left-right direction are assembled in a grid pattern and fixed by screwing, and a single piece attached to the front of the frame 20 with the same contour via a reinforcing plate 23. It is composed of the ceramic tile plate 24 of the above.

The ceramic tile plate 24 to be the decorative plate on the wall surface has a large area of about 1800 mm in length and 850 mm in width, and is formed of an integral ceramic tile having a thickness of 6 mm to 10 mm. Here, in the conventional ceramic tile construction of an interior wall, it is difficult to carry such a large area ceramic tile plate to the construction site without damaging it, and the ceramic tile divided into a plurality of small areas is cemented. It was attached to the base such as gypsum board by the wet method using the above and the crimping method using the adhesive. Therefore, it takes skilled craftsmen to smooth the base surface and the surface consisting of a large number of ceramic tiles, and at the construction site, cement scraps, tile scraps, packing materials for packing ceramic tiles, etc. Waste was generated. In the present embodiment, a wall panel 2 made of one ceramic tile plate 24 having a large decorative plate area is manufactured in advance at a manufacturing factory, and a plurality of wall panels 2 and 2 are connected to construct the inner wall 10. In particular, since the connected wall panels 2 are aligned by the guide rails 4 along one straight line, the wall surface of the ceramic tile naturally becomes a smooth surface, and the waste as described above at the construction site is also generated. Does not occur.

The reinforcing plate 23 laminated on the back side of the ceramic tile plate 24 is a lightweight plate material such as a calcium silicate plate, a flexible board, and a magnesium oxide plate, and is formed to have the same outer shape as the ceramic tile plate 24. The large-area ceramic tile plate 24 is reinforced by being fixed to the rear surface of the 24.

The vertical rails 21 and the horizontal rails 22 constituting the frame 20 are each made of hard metal materials such as aluminum, zinc-plated steel, and stainless steel, which are hard to be deformed, and are arranged vertically on both the left and right sides of the wall panel 2. As shown in FIG. 7, the vertical rail 21 is an H-shaped steel in which flanges 21a and 21b orthogonal to the web are integrally formed on both sides of the web in the front-rear direction, and the rear flange 21b is a large-load ceramic tile. It is formed in the shape of a thick rectangular pipe so that the vertical crosspiece 21 is not deformed even if the plate 24 is supported.

The cross rail 22 is integrally divided into three stages in the vertical direction by three webs 22c, 22d, 22e along the horizontal plane between the two strip-shaped support pieces 22a and 22b having the longitudinal direction in the left-right direction. It is formed by connecting. Therefore, in the uppermost web 22c, the lowermost web 22e, and the two strip-shaped support pieces 22a and 22b, the upper end and the lower end of the cross rail 22 have a gutter shape that opens upward and downward along the left-right direction, respectively. It has become. Further, dowel holes 25a and 25b through which the dowel pin 51 described later is inserted are bored along the vertical direction at two positions of the uppermost web 22c and the middle web 22d of the cross rail 22, respectively.

Since the reinforcing plate 23 is fixed to the front surface of the frame body 20 with an adhesive, the front surface of the strip-shaped support piece 22a in front of the cross rail 22 is exposed on the same surface as the flange 21a in front of the vertical rail 21. Further, the left and right ends of the two strip-shaped support pieces 22a and 22b are narrowed inward so as to abut on the inner wall surface of the flanges 21a and 21b of the vertical rail 21. As a result, both ends of the cross rail 22 come into contact with the webs of the vertical rails 21 and 21 arranged on the left and right sides of the wall panel 2, so that a male screw (not shown) for inserting the web of the vertical rail 21 is inserted in the middle of the cross rail 22. A screw hole formed in the web 22d is screwed to a recessed female screw portion 22f (see FIG. 3), and a horizontal rail 22 is hung and attached between the vertical rails 21 and 21 along the left-right direction.

As shown in FIG. 3, the lowermost horizontal rail 22 attached along the lower end of the wall panel 2 is attached between the vertical rails 21 and 21 with the other horizontal rails 22 turned upside down, and is attached to the lowermost horizontal rail. Both ends of the two strip-shaped support pieces 22a and 22b of the cross rail 22 and both sides of the web of the vertical rails 21 and 21 are cut out from the lower end at the height of the rail 41a of the guide rail 4. .. As a result, the pair of rails 41a and 41a of the guide rail 4 are cut out from the opposite inner surfaces of the two strip-shaped support pieces 22a and 22b of the lowermost horizontal rail 21 and the lower ends of the webs of the vertical rails 21 and 21. It engages with the notch groove and guides the wall panel 2 movably along the guide rail 4.

As shown in FIG. 1, a downward lock plate 26a and an upward lock plate 26b that engage with each other are attached to the flanges 21b behind the left and right vertical rails 21 along the rear surface of the flanges 21b, and adjacent wall panels 2 are attached. 2 is aligned along the left-right direction, which is the connecting direction, by a rail 41a composed of two parallel linear protrusions of the guide rail 4, and is arranged upright between the two through a joint post 6. , The downward lock plate 26a and the upward lock plate 26b are engaged and connected.

As shown in FIG. 7, the joint post 6 is made of a hard metal material such as aluminum, galvanized steel, and stainless steel that is hard to be deformed. A set of vertically elongated plate-shaped post-side flanges 62, 62 that are orthogonal to each other and have a flat surface in the left-right direction are integrally formed. The width of the post-side web 61 in the front-rear direction is substantially equal to the width of the web of the vertical rail 21 in the front-rear direction. Fits between 21b.

Therefore, in the vertical rails 21 and 21 of the adjacent wall panels 2 and 2 and the joint post 6 arranged between them, the connecting portions having an H-shaped cross-sectional shape overlap each other along the connecting direction and are interposed via the joint post 6.
