Description

  The present invention relates to a mounting structure for a wall panel such as a handrail panel of a building such as a multilevel parking lot, and a panel mounting bracket.

  Conventionally, as this type of wall panel mounting structure, for example, as shown in FIG. 6, panel support frames 20 having an H-shaped cross section are erected at predetermined intervals around a parking lot. Panel mounting brackets 22 and 22 having a substantially mountain-shaped cross section are disposed on both sides of the web 21 of each panel support frame 20. At this time, the first flange 23 of the panel mounting bracket 22 is arranged in parallel with a certain distance from the first flange 24 of the panel support frame 20, and the second flange 25 is arranged along the web 21. With the one end 26 a of the wall panel 26 inserted between the first flanges 23 and 24, the bolts 27 are passed through the second flange 25 and the web 21 and fastened to the nuts 28. Thus, the first portion of the panel mounting bracket 22 is pressed by pressing both panel mounting brackets 22 and 22 toward the web 21 while the abutting portion 29 at the tip of the second flange 25 of the panel mounting bracket 22 is pressed against the web 21. There is one in which one end 26a of the wall panel 26 is pressed and fixed to the first flange 24 side of the panel support frame 20 by the flange 23 (see Patent Document 1). According to this, an external scaffold is not required when the wall panel 26 is attached, and the attachment work can be performed safely from the inside of the building.

JP 2002-146958 A

However, the wall panel mounting structure is such that the bolts 27 and nuts 28 are tightened so that the panel mounting bracket 22 rotates the second flange 25 to the web 21 side by a small amount with the abutting portion 29 as a fulcrum. In accordance with this, the one end portion 26a of the wall panel 26 is pressed and fixed to the first flange 24 side of the panel support frame 20 by the first flange 23. According to this, the bolt 27 and the nut 28 are used. A predetermined tightening force is required, but due to the difference in the skill level of the tightening operator, insufficient tightening or excessive tightening variation tends to occur, and it is difficult to obtain a certain tightening state. Wall panels 26 If it is insufficient tightening backlash in panel support frame 20 inside, scratches and locally strongly pressed against over tightening tip of the inner surface of the edge portion wall panels 26 of the first flange 23, the Rainwater enters the damaged area and causes rust. Further, when the bolts 27 and nuts 28 are loosened due to the vibration of the building, there is a problem that the wall panel 26 is likely to rattle.

  The present invention has been made in order to solve such problems. The object of the present invention is to provide a panel support frame having an H-shaped cross section as described above, with one side end portion of the wall panel attached to the panel. In the wall panel mounting structure that is fixed with the mounting bracket, problems such as insufficient tightening or excessive tightening, such as conventional bolts and nuts, and loosening of bolts and nuts due to vibration, by devising the cross-sectional shape of the panel mounting bracket itself It is an object of the present invention to provide a wall panel mounting structure and a panel mounting bracket that can eliminate the above-mentioned problem and can always ensure a stable and surely strong mounting state.

The wall panel mounting structure according to the present invention will be described with reference to the reference numerals shown in FIGS. 1 to 5 to facilitate understanding of the contents of the invention. A plurality of panel support frames (1) which are formed in a cross-sectional H shape having first and second flanges (5) and (6) at both ends of the frame, and are erected at predetermined intervals in the horizontal direction Between the wall panel (2) disposed between the frames (1) and (1), between the second flange ( 6 ) of the panel support frame (1) and one end (2a) of the wall panel (2). In the wall panel mounting structure provided with the panel mounting bracket 3 (and) arranged along the longitudinal direction of the panel support frame (1), the panel mounting bracket (3) is made of an elastic metal plate material. Facing the web (4) of the panel support frame (1) Via an E unit (7), the one end of the web first flange fold to one edge continuously provided by panel support frames (7) (1) (5) wall panels (2) (2a) A first flange (8) opposed to each other, and a first end that is folded back from the protruding end of the first flange to the outside of the first flange and elastically contacts the inner surface of the one side end (2a) of the wall panel (2). A folding plate (9) and a second flange (10) that is bent and connected to the other end edge of the web (7) and elastically contacts the inner surface of the second flange (6) of the panel support frame (1). It is formed in a shape and is characterized in that the web (7) of the panel mounting bracket (3) is fixed to the web (4) of the panel support frame (1) with a self-drilling screw (11).

According to such a configuration, the panel mounting bracket is elastically deformed so as to reduce the folding angle between the first flange and the first folded plate between the second flange of the panel support frame and one end of the wall panel. As a result of this elastic restoring action, the second flange of the panel mounting bracket strongly stretches against the second flange of the panel support frame, and the first folded plate of the panel mounting bracket connects one end of the wall panel to the first of the panel support frame. An attachment state is obtained in which the inner surface of the flange is strongly pressed and fixed. Therefore, it is possible to obtain a mounting strength equal to or higher than that of the conventional bolts and nuts mentioned above, problems such as insufficient tightening and excessive tightening like conventional bolts and nuts, and loosening of bolts and nuts due to vibration. The problem can be solved, and a stable and secure mounting state can always be secured.
Due to the elastic restoring action of the panel mounting bracket, the second flange strongly stretches against the second flange of the panel support frame, and the first folded plate of the panel mounting bracket connects one end of the wall panel to the first flange of the panel support frame. By pressing firmly on the inner surface, the wall panel is pushed back by the repulsive force of the first flange and the first folded plate even if the wall panel receives a wind load (positive pressure) from the outside and is pushed inward. Therefore, the wall panel does not rattle in the panel support frame.

The web of the panel mounting bracket is fixed to the web of the panel support frame with a self-drilling screw. The purpose of use of this self-drilling screw is different from the purpose of use of the bolt 27 and nut 28 for fastening the conventional panel mounting bracket 22 shown in FIG. This is only to prevent the panel mounting bracket from protruding outward from between the second flange of the panel support frame and one side end of the wall panel. Therefore, the fixing operation with the self-drilling screw is not as severe as the conventional tightening operation with the bolt 27 and the nut 28, and the self-drilling screw is simply inserted into the panel mounting bracket web and the panel support frame web. Simple work is enough.

According to a first aspect of the present invention, in the wall panel mounting structure, as described in the second aspect , the second flange (10) of the panel mounting bracket (3) is connected to the projecting end of the second flange. A second folded plate (12) that is folded outward and elastically contacts the inner surface of the second flange (6) of the panel support frame (1) may be provided. Accordingly, the panel mounting bracket is elastically deformed so as to reduce the folding angle between the second flange and the second folded plate between the second flange of the panel support frame and one side end of the wall panel, Combined with the elastic deformation that reduces the folding angle with the first folding plate, the elastic restoring action increases. Therefore, even if the wall panel receives a wind load from the outside and is pushed inward, the repulsive force by the first flange and the first folding plate of the panel mounting bracket and the second flange and the second folding plate Since it pushes back strongly with repulsive force, it can prevent more reliably the shakiness in the panel support frame of a wall panel.

As described in claim 3, the panel mounting bracket of the present invention is formed in a cross-sectional H shape having first and second flanges (5) and (6) at both ends of the web (4), and is horizontally spaced at a predetermined interval. The second flange ( 6 ) of the panel support frame (1) standing upright and the one end of the wall panel (2) disposed between the adjacent panel support frames (1), (1) ( 2a), in the panel mounting bracket 3 arranged along the longitudinal direction of the panel support frame (1),
A web (7) made of a metal plate having elasticity, arranged opposite to the web (4) of the panel support frame (1) and fixed to the web (4) with a self-drilling screw (11), and one end edge of the web A first flange (8) that is bent and connected to the first flange (5) of the panel support frame (1) through one end (2a) of the wall panel (2), and the first flange. A first folded plate (9) which is folded back from the protruding end of the first flange and elastically contacts the inner surface of one end (2a) of the wall panel (2), and the other end of the web (7) It is characterized in that it is formed in a shape having a second flange (10) that is bent and connected to the edge and elastically contacts the inner surface of the second flange (6) of the panel support frame (1).

According to the panel mounting bracket having such a configuration, the panel mounting bracket is disposed between the second flange of the panel support frame and one side end portion of the wall panel, whereby the first flange and the first folded plate are arranged. The second flange of the panel mounting bracket is strongly stretched against the second flange of the panel support frame by this elastic restoring action, and the first folded plate of the panel mounting bracket is one of the wall panels. An attachment state is obtained in which the side end is strongly pressed and fixed to the inner surface of the first flange of the panel support frame. Therefore, it is possible to obtain a mounting strength equal to or higher than that of the conventional bolts and nuts mentioned above, problems such as insufficient bolting and excessive tightening as with conventional bolts and nuts, and loosening of bolts and nuts due to vibration. The problem can be solved, and a stable and secure mounting state can always be secured.
Due to the elastic restoring action of the panel mounting bracket, the second flange strongly stretches against the second flange of the panel support frame, and the first folded plate of the panel mounting bracket connects one end of the wall panel to the first flange of the panel support frame. It is possible to obtain a panel mounting state in which the inner surface is strongly pressed and fixed. As a result, the wall panel is pushed back by the repulsive force of the first flange and the first folded plate even if the wall panel receives a wind load (positive pressure) from the outside and is pushed inward. Shaking in the support frame can be prevented.

The panel mounting bracket web is fixed to the panel support frame web with a self-drilling screw. The purpose of the self-drilling screw is to use bolts 27 and nuts 28 for fastening the conventional panel mounting bracket 22 shown in FIG. Unlike the purpose, it is only to prevent the panel mounting bracket from protruding outward from between the second flange of the panel support frame and one side end of the wall panel. Therefore, the fixing operation with the self-drilling screw is not as severe as the conventional tightening operation with the bolts 27 and nuts 28. The self-drilling screw is simply inserted into the panel mounting bracket web and the panel support frame web. Simple work is enough.

In the panel mounting bracket according to claim 3, the second flange (10) of the panel mounting bracket (3) is disposed outside the second flange from the protruding end of the second flange. It may be provided with a second folded plate (12) that is folded back and elastically contacts the inner surface of the second flange (6) of the panel support frame (1). As a result, the panel mounting bracket is elastically deformed so as to reduce the folding angle between the second flange and the second folded plate even between the second flange of the panel support frame and one side end of the wall panel. The elastic restoring action increases in combination with the elastic deformation that reduces the folding angle between the 1 flange and the first folded plate. Therefore, even if the wall panel receives a wind load from the outside and is pushed inward, the repulsive force by the first flange and the first folding plate of the panel mounting bracket and the second flange and the second folding plate Since it is strongly pushed back by the repulsive force, it is possible to more reliably prevent the wall panel from rattling in the panel support frame.

  According to the present invention, it is possible to solve problems caused by insufficient or excessive tightening, such as conventional bolts and nuts, and loosening of bolts and nuts due to vibration, and always stably and securely attach a wall panel to a panel support frame. Can do.

  A preferred embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a sectional view of a wall panel mounting structure showing an embodiment of the present invention, and FIG. 2 is a sectional view of a panel mounting bracket.

  The overall structure of the wall panel mounting structure according to the present invention is the same as that of the conventional example shown in FIG. 6, and as shown in FIG. A plurality of panel support frames 1 made of H-shaped steel (only one panel support frame 1 is shown in FIG. 1) and a steel plate panel or sandwich panel disposed between adjacent panel support frames 1 and 1 And the like, and a panel mounting bracket 3 disposed in each panel support frame 1 along the longitudinal direction of the panel support frame 2.

  Each panel support frame 1 is formed in a cross-sectional H shape having first, second and fifth flanges 5 and 6 at both ends of the web 4, and is installed with the first flange 5 on the outside and the second flange 6 on the inside of the building. The

The panel mounting bracket 3 is made of an elastic metal plate such as a thin steel plate (for example, 0.5 mm thick). As shown in FIG. 2, the panel 7 is connected to the web 7 and one end edge of the web 7 at a substantially right angle. The first flange 8, the first folded plate 9 folded back from the protruding end of the first flange 8 to the outside of the first flange 8 and longer than the length of the first flange 8, and the other end of the web 7 consisting through material formed on the cross-section shape and a second flange 10 which is substantially at right angles bent continuously provided in the same direction as the first flange 8. Note that the protruding end edge 9a of the first folded plate 9 is folded outward. The distance H between the projecting end edge 9a of the first folded plate 9 and the second flange 10 of the panel mounting bracket 3 before mounting (see FIG. 2) is determined by placing the wall panel 2 in the panel support frame 1 at one side end thereof. The dimension W of the gap between the inner surface of one side end 2a of the wall panel 2 and the inner surface of the second flange 6 formed when the outer surface of the portion 2a is placed in contact with the inner surface of the first flange 5 (see FIG. 1). ) Is set to be larger.

Next, a construction procedure for attaching the wall panel 2 between the panel support frames 1 and 1 erected at predetermined intervals in the horizontal direction will be described.
First, a panel mounting bracket 3 in the panel support frame 1 makes the web 7 face the web 4 of the panel support frame 1 at a certain interval, and the first folded plate 9 is placed on the first flange 5 of the panel support frame 1. The panel support frame 1 is disposed along the longitudinal direction of the panel support frame 1 so as to be opposed to each other with a certain interval and so that the second flange 10 is opposed to the second flange 6 of the panel support frame 1. Then, the self-drilling screw 11 is inserted over the web 7 of the panel mounting bracket 3 and the web 4 of the panel support frame 1. Since this self-drilling screw 11 is only for preventing the panel mounting bracket 3 from protruding outward (in the direction of arrow B in FIG. 1) from the panel support frame 1, it is not always necessary for the head 11a of the self-drilling screw 11 to It is not necessary to tighten until the seat surface 11b comes into close contact with the web 7. The seat surface 11b may be slightly separated from the web 7. The tightening adjustment is not important, and even an unskilled person can easily perform it.

Next, the wall panel 2 is dropped such that one side end portion 2 a enters between the first flange 5 of the panel support frame 1 and the first folded plate 9 of the panel mounting bracket 3. When the wall panel 2 is dropped, the panel mounting bracket 3 is folded between the first flange 8 and the first folded plate 9 between the second flange 6 of the panel support frame 1 and the one end 2a of the wall panel 2. It will be in the state which elastically deformed so that may be reduced. Due to the elastic restoring action of the panel mounting bracket 3, the second flange 10 is elastically brought into contact with the inner surface of the second flange 6 of the panel support frame 1 and is strongly stretched, and the protruding edge 9 a of the first folded plate 9 is the wall panel 2. An attachment state is obtained in which the one end portion 2a is elastically brought into contact with the inner surface of the first end portion 2a and is firmly pressed against the inner surface of the first flange 5 of the panel support frame 1.
Since the wall panel 2 is dropped from the floor of the building, it can be easily constructed without the need for an external scaffold, and the construction period can be greatly shortened compared to construction requiring an external scaffold.

The wall panel 2 can be attached by the following construction procedure instead of the above-described installation procedure. First, the wall panel 2 is dropped so that one end portion 2 a of the wall panel 2 enters between the first flange 5 and the second flange 6 of the panel support frame 1. Next, the panel mounting bracket 3 and the web 7 face the web 4 of the panel support frame 1 in the gap between the second flange 6 of the panel support frame 1 and the inner surface of the one side end 2 a of the wall panel 2. In addition, the first folded plate 9 is elastically contacted against the inner surface of the one side end 2a of the wall panel 2, and the second flange 10 is elastically contacted against the second flange 6 of the panel support frame 1. By pushing in like this, the panel support frame 1 is arranged along the longitudinal direction.
By pushing the panel mounting bracket 3 in this way, the panel mounting bracket 3 is also connected between the first flange 8 and the first folded plate between the second flange 6 of the panel support frame 1 and the one end 2a of the wall panel 2. 9 is in a state of being elastically deformed so as to reduce the folding angle. Due to the elastic restoring action of the panel mounting bracket 3, the second flange 10 is strongly stretched against the second flange 6 of the panel support frame 1, and the protruding end edge 9 a of the first folded plate 9 is the one end 2 a of the wall panel 2. An attachment state is obtained in which the one side end 2a is strongly pressed against and fixed to the inner surface of the first flange 5 of the panel support frame 1 by elastic contact with the inner surface.
Finally, the self-drilling screw 11 is inserted through the web 7 of the panel mounting bracket 3 and the web 4 of the panel support frame 1.

  When the wall panel 2 is mounted using the panel mounting bracket 3 as described above, the second flange 10 strongly stretches against the second flange 6 of the panel support frame 1 due to the elastic restoring action of the panel mounting bracket 3, and the first folding is performed. The plate 9 strongly presses and fixes the one side end 2a of the wall panel 2 to the inner surface of the first flange 5 of the panel support frame 1, so that a stable and surely strong mounting state is always obtained.

The second flange 10 of the panel mounting bracket 3 strongly stretches against the second flange 6 of the panel support frame 1, and the first folded plate 9 of the panel mounting bracket 3 connects the one side end 2 a of the wall panel 2 to the panel support frame 1. Since the wall panel 2 receives wind load from the outside (in the direction of arrow A in FIG. 1), the repulsive force of the first flange 8 and the first folding plate 9 Since the wall panel 2 is pushed back, the wall panel 2 does not rattle in the panel support frame 1.
Further, since the panel mounting bracket 3 projects the bent portion 10a connected to the web 7 of the second flange 10 against the inner surface of the second flange 6 of the panel support frame 1, the panel mounting bracket 3 is also directed in the direction of arrow B of the panel mounting bracket 3. Can be prevented from protruding.

  The panel mounting brackets 3 are arranged on both sides of the web 4 of each panel support frame 1, and are inserted through the web 7 of the panel mounting bracket 3 on one side and project to the other side of the web 4 of the panel support frame 1. The tip end portion 11c of the drill screw 11 is covered with a web 7 of the panel mounting bracket 3 on the other side. Incidentally, the part where the self-drilling screw 11 is inserted into the web 7 of the panel mounting bracket 3 on one side and the part where the self-drilling screw 11 is inserted into the web 7 of the panel mounting bracket 3 on the other side are vertically long. It is shifted in the direction.

As a cross-sectional shape of the panel mounting bracket 3, it can also be formed in a cross-sectional shape as shown in FIGS. The panel mounting bracket 3 shown in FIG. 3 is the panel mounting bracket shown in FIG. 2 except that the second flange 10 is bent at a substantially right angle in the opposite direction to the first flange 8 at the other end edge of the web 7. 3 are the same as those in FIG.
The panel mounting bracket 3 shown in FIG. 4 is formed in a shape having a second folded plate 12 folded back from the protruding end of the second flange 10 to the outside of the second flange 10. Since it is the same as that of the metal fitting 3, the same reference numerals are given to the same parts, and the description thereof is omitted. Incidentally, the distance dimension H (see FIG. 4) between the protruding end edge 9a of the first folded plate 9 and the projected end edge 12a of the second folded plate 12 of the panel mounting bracket 3 before mounting is set in the panel support frame 1 in the wall. Between the inner surface of the one side end portion 2a of the wall panel 2 and the inner surface of the second flange 6, which is formed when the panel 2 is stored so that the outer surface of the one side end portion 2a contacts the inner surface of the first flange 5. It is set to be larger than the gap dimension W (see FIG. 5).

  As shown in FIG. 5, when the wall panel 2 is mounted on the panel support frame 1 using the panel mounting bracket 3 having the second folding plate 12 of FIG. 12 can be elastically brought into contact with the inner surface of the second flange 6 of the panel support frame 1. According to this, the panel mounting bracket 3 reduces the folding angle between the second flange 10 and the second folded plate 12 between the second flange 6 of the panel support frame 1 and the one side end 2a of the wall panel 2. The elastic restoring action can be increased in combination with the elastic deformation that is elastically deformed and reduces the folding angle between the first flange 8 and the first folded plate 9. Therefore, even if the wall panel 2 receives a wind load from the outside (in the direction of arrow A in FIG. 5) and is pushed inward, the first flange 8 and the first folding plate 9 of the panel mounting bracket 3 are used. Therefore, the wall panel 2 can be more reliably prevented from rattling in the panel support frame 1 because it is strongly pushed back by the repulsive force caused by the above and the repulsive force caused by the second flange 10 and the second folded plate 12.
