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. Further, a receiving steel material 4 made of L-shaped steel is welded to the pillar 3 for every five ALC panels, for example, to receive and support the lower end surfaces of the left and right ALC panels 1. The hook bolts 2 mainly receive a force acting in a direction perpendicular to the ALC panel 1, and the receiving steel member 4 receives the weight of the ALC panel 1.

(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, the rainwater may invade through the crack to 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.

In order to avoid such a situation, for example, the following configuration can be considered. Embed anchor nuts in the ALC panel in advance. On the other hand, a mounting plate with a horizontally elongated hole is manufactured, and a bolt is passed through the elongated hole and screwed into an anchor nut of the ALC panel to attach it to the ALC panel so as to be movable in the long diameter direction of the elongated hole. Fix the mounting plate to the pillar by welding, etc. This allows the ALC panel to move laterally with respect to the column by the length of the long hole, so
It is possible to absorb relative displacement with the ALC panel and prevent unreasonable force from acting on the ALC panel.

However, in the above configuration, since the mounting plate is sandwiched between the ALC panel surface and the bolt head, in order to secure the mobility of the mounting plate, the position of the bolt head with respect to the ALC panel surface is appropriately set. And have to. For this reason, it is necessary to finely adjust the tightening amount of the bolts, which not only takes time and effort for the mounting work, but also causes a problem that the tightening is excessively tightened due to variations in the work and eventually the mobility of the mounting plate is impaired. It's easy and not very reliable.

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 on both ends of a wall panel in a building structure with a vertically long pillar. A receiving angle that is fixed to the back side of the wall panel is provided, and an end face U-shaped mounting bracket that has one end fixed to the receiving angle in a horizontal direction is provided, and the base end is on the back side of the wall panel. The present invention is characterized in that a mounting member that is fixed and has a hole at the other end is provided, and a mounting shaft that is commonly inserted into a horizontally elongated slide hole that is vertically penetrated through the hole and the mounting bracket is provided. .

(Operation) According to the above means, the wall member is attached to the pillar of the skeleton by locking the attachment member to the attachment fitting via the attachment shaft. At this time, since the mounting shaft can move within the slide hole of the mounting member, the lateral movement of the mounting member relative to the mounting member is allowed. Therefore, even if the wall panel and the body are relatively displaced laterally due to an earthquake or the like, the displacement can be absorbed and an unreasonable force does not act on the wall panel.

(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 4.

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
(~ 5 sheets) is one block, and in each block,
A receiving member (14) is fixed to a receiving angle (13) so as to correspond to the lower surfaces of both ends of the ALC panel (12) located at the lowest position.

Then, for the lowest ALC panel 12 of each block, the stepped fixing plate 17 is fixed by the bolts 16 located on the left and right sides of the block and screwed into the anchor nuts 15 (see FIGS. 3 and 4). There is. Its fixed plate
The tip of 17 is fixed to the receiving angle 13 by welding, whereby the ALC panel 12 is fixed to the pillar 11. Further, the lower surfaces of both ends of the ALC panel 12 are received and supported by the receiving member 14.

Now, as for the ALC panel 12 located above the lowest position in each block, eyebolts 18, which are mounting members, are fixed by being screwed into the anchor nuts 15 on the left and right sides of the rear surface as shown in FIGS. 3 and 4. Has been done. On the other hand, a U-shaped mounting bracket 19 corresponding to the eyebolt 18 is fixed to the receiving angle 13 by welding, for example. The eyebolt 18 penetrates a window portion 19a next to the mounting member 19, and an annular portion 18a on the base end side is located inside the mounting member 19. At this time, the hole 18b of the annular portion 18a is opened vertically. As shown in FIG. 1, a laterally long window portion 19a is formed on the front surface of the mounting bracket 19, and laterally long slide holes 19b and 19b which are opened in the vertical direction are formed on the upper and lower horizontal planes. The mounting shaft 20 penetrates through the slide holes 19b, 19b of the mounting bracket 19 and the hole 18b of the eyebolt 18.
The mounting shaft 20 is made of, for example, a bolt, and is inserted from above into the slide hole 19b of the mounting bracket 19, the hole portion 18b of the eyebolt 18, and the slide hole 19b in that order, and the head 20a of the mounting shaft 19 is mounted on the mounting bracket 19.
Is locked to the upper surface of. Thereby, the eyebolt
18 is locked to the mounting bracket 19 through the mounting shaft 20 in a state where the vertical direction and the direction perpendicular to the panel surface are retained.
The ALC panel 12 is attached to the pillar 11 of the body. At this time, since the mounting shaft 20 can be moved within the horizontally long slide hole 19b of the mounting bracket 19, the eyebolt 18 has the slide hole 19b.
Within the range, the lateral movement relative to the mounting bracket 19 is allowed integrally with the mounting shaft 20.

Although not shown, the vertical and horizontal joints between the ALC panels 12 are filled with a flexible sealing material for waterproofing.

In the above configuration, even if the ALC panel 12 and the pillar 11 are relatively displaced in the lateral direction due to an earthquake, for example, the lateral movement of the eyebolt 18 with respect to the mounting bracket 19 causes the ALC to move.
Since the panel 12 is allowed to shift with respect to the pillar 11, the displacement can be absorbed.

Also, in this case, when installing the ALC panel 12,
The eyebolt 18 can be easily worked without requiring strictness in tightening amount, etc.
The process is as simple as inserting the mounting shaft 20 after fixing the mounting bracket 19 to the angle 13 as well as fixing to the C panel 12, so the mounting work can be done easily and without any hassle. .

Thus, according to the present embodiment, unlike the conventional one in which the ALC panel 12 is fixed to the pillar 11, the pillar 1 of the ALC panel 12 is
Since the movement allowance with respect to 1 is surely guaranteed, it is possible to surely prevent an unreasonable force from being applied to the ALC panel 12 due to an earthquake or the like, and thereby to sufficiently improve the durability and the mounting reliability of the ALC panel 13. Is something that can be done.

In the above embodiment, the anchor nut 15 is installed inside the ALC panel 12.
However, the eye bolt may be penetrated through the ALC panel and the nut may be screwed into the eye bolt from the outside of the ALC panel. Further, the mounting member is not limited to the eyebolt 18, and may be, for example, a plate-shaped member having a hole or the like, and may be fixed to the reinforcing bar in the wall panel, an anchor metal fitting or the like by welding. Further, various modifications can be considered as the shape of the mounting shaft.

Besides, the present invention may be applied to not only the ALC panel but also a mounting structure of a precast concrete plate, and the present invention can be appropriately modified and implemented within the scope not departing from the gist.

[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.
