Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial field of application) The present invention relates to a wall panel mounting structure with improved seismic resistance.

(Prior Art) As one type of wall panel mounting structure, for example, a horizontal wall bolting construction method is known in which a large number of lightweight cellular concrete panels (hereinafter referred to as "ALC panels") are horizontally mounted on a frame to form an outer wall of a building. There is. As schematically shown in FIG. 5, hook bolts 2 are fixed to the left and right ends of each ALC panel 1 in a penetrating state, and the tips of the hook bolts 2 are welded to a pillar 3 of a skeleton. In addition, for example, every five ALC panels 1 are provided on the pillars 3 with a receiving steel material 4 made of L-shaped steel.
Are welded to receive and support the lower end surfaces of the left and right ALC panels 1. The hook bolts 2 are mainly ALC panel 1
The receiving steel material 4 receives the weight of the ALC panel 1 under the force acting in the direction perpendicular to the.

(Problems to be solved by the invention) However, the body and the wall panel are relatively displaced during an earthquake. However, in the above-mentioned conventional configuration, since the pillar 3 and the ALC panel 1 are fixedly attached via the hook bolts 2, an unreasonable force acts on the ALC panel 1, which may cause cracking depending on the degree of displacement. May occur. When such a crack occurs, rainwater may invade through the crack and significantly damage the building, and the expansion of the crack may cause a dangerous situation such as a fragment of a wall panel falling. is there.

The present invention has been made in view of the above circumstances, and an object thereof is to reliably prevent an unreasonable force from being applied to a wall panel due to an earthquake or the like, thereby sufficiently improving the durability and the mounting reliability of the wall panel. It is to provide a wall panel mounting structure that can be made.

[Structure of the Invention] (Means for Solving the Problems) A wall panel mounting structure according to the present invention is a structure in which a horizontally long wall panel is mounted by supporting both end portions of the wall panel on a building frame. The pillar is provided with a receiving angle that extends in the vertical direction and is directed to the back surface of the wall panel, and one end side is fixed to the wall panel and the other end side is provided with a mounting plate positioned so as to sandwich the receiving angle from the back side. It is characterized in that a guide member, which is sandwiched between the angle and a lateral movement, is provided on the receiving angle.

(Operation) According to the above means, the wall plate is attached to the pillar of the skeleton by the attachment plate being locked to the receiving angle in a movement restricting state in a direction perpendicular to the panel surface. And
Since the mounting plate is supported in a state where it can move laterally with respect to the receiving angle, even if the wall panel and the frame are relatively displaced laterally due to an earthquake, etc. It can be absorbed and the wall panel is not subjected to excessive force.

(Embodiment) An embodiment in which the present invention is applied to a lateral wall construction method of an ALC panel will be described with reference to FIGS. 1 to 3.

Figure 2 shows the overall structure as seen from the inside of the building. As shown in the figure, each pillar 11 constituting the frame is made of H-shaped steel and is erected in a row at an interval equal to the lateral dimension of the ALC panel 12 which is a wall panel. On the outer surface of the building among the pillars 11, two receiving angles 13 extending in the vertical direction are paired left and right and are fixed along the pillars 11 by welding. The ALC panel 12 is vertically stacked between the columns 11 and is attached as will be described later in a state in which the back surfaces of both end portions are directed to the receiving angles 13 and verticality is ensured. In addition, multiple ALC panels 12 (3
(About 5 sheets) is one block, and the receiving member 14 is fixed to the receiving angle 13 corresponding to the lower surfaces of both ends of the ALC panel 12 located at the bottom of each block.

Now, for the ALC panel 12 at the bottom of each block,
A stepped fixing plate 17 is fixed by bolts 16 located on the left and right sides thereof and screwed into an anchor nut 15 (see FIG. 3). The tip of the fixed plate 17 is fixed to the receiving angle 13 by welding, which allows the AL
The C panel 12 is fixed to the pillar 11. Also, ALC panel 12
The lower surfaces of both ends of are received and supported by the receiving member 14.

On the other hand, ALC panel 1 located above the bottom of each block
A mounting plate 18 is mounted on both left and right sides of 2 by bolts 16 screwed into an anchor nut 15, and the tip side of the mounting plate 18 is supported by a receiving angle 13. As shown in FIG. 1, the mounting plate 18 has a stepped shape, and a rising portion 18a is bent and formed at the tip. Further, as shown in FIG. 3, the tip end side of the mounting plate 18 is positioned so that the receiving angle 13 is sandwiched between it and the panel 12. Further, a plate-shaped guide member 19 having a substantially U-shaped side surface is attached to the receiving angle 13, for example, by welding, and is sandwiched between the tip end side portion of the attachment plate 18 and the receiving angle 13. At this time, the guide member 19 sandwiches the mounting plate 18 with leaving a slidable margin, so that the mounting plate 18 is restricted from moving in the vertical direction and the vertical direction with respect to the ALC panel 12 surface. With the receiving angle with lateral movement allowed
Backed by 13. In this case, the assembly procedure is
First, the mounting plate 18 may be fixed to the ALC panel 12 with the bolts 16 while the ALC panel 12 is received on the angle 13, and then the guide member 19 may be welded to the angle 13.

The joint portion between the ALC panels 12 is filled with a filler 20 such as rock wool.

In the above structure, even if the ALC panel 12 and the pillar 11 are relatively displaced laterally due to an earthquake, for example, the mounting plate 18
Since the lateral movement of the ALC panel 12 with respect to the receiving angle 13 allows the sliding movement of the ALC panel 12 with respect to the column 11, the displacement can be absorbed. Further, the ALC panel 12 does not come off the receiving angle 13 due to the rising portion 18a at the tip of the mounting plate 18.

Therefore, according to this embodiment, unlike the conventional one in which the ALC panel 12 is fixed to the pillar 11, the movement allowance of the ALC panel 12 with respect to the pillar 11 is surely guaranteed, so that an earthquake or the like may occur. It is possible to reliably prevent the ALC panel 12 from being subjected to an unreasonable force, and thereby sufficiently improve the durability and mounting reliability of the ALC panel 12.

FIG. 4 shows another embodiment of the present invention. The difference from the above embodiment is that a guide member 21 made of a wire is provided in place of the plate-like guide member 19. The guide member 21 is also sandwiched in a state in which it is allowed to move laterally between the guide member 21 and the receiving angle portion 13 of the mounting plate 18, and the other portions are the same as in the above-described embodiment. Therefore, even in such a configuration, the same effect as that of the above embodiment can be obtained.

It should be noted that the present invention is not limited to the embodiments described above and shown in the drawings.For example, other than a mode in which the anchor nut 15 is embedded in the ALC panel 12, a bolt is passed through the ALC panel and the ALC panel is attached to the bolt. Alternatively, the nut may be screwed from the outside of the panel. Further, the present invention can be applied to not only ALC panels but also a mounting structure of precast concrete boards, and various modifications can be made without departing from the scope of the invention.

[Effects of the Invention] As is clear from the above description, according to the wall panel mounting structure of the present invention, the wall panel is reliably guaranteed to move, and an unreasonable force is exerted on the wall panel due to an earthquake or the like. This has an excellent effect that it is possible to reliably prevent this, and thereby to sufficiently improve the durability and the mounting reliability of the wall panel.
