Abstract

PURPOSE:To enhance construction properties by suspending the upper end of a lower exterior wall panel from a structural body by means of a vertical bolt, and inserting a pin portion formed at the upper end of a bolt into a positioning hole provided at the lower end of an upper exterior wall panel. CONSTITUTION:A support plate 6 is secured to the upper horizontal frame 4 of an exterior wall panel 1 at one end via a vertical bolt 7. The other end of the plate 6 is secured to the beam 10 of a structural body via a mounting bolt and the like. Next, a pin portion 20 projected integrally with the upper end of the bolt 7 is inserted into a positioning hole 21 formed in the lower horizontal frame 4 of another panel 1 to be installed on the upper side. The lower end of the exterior wall panel can then be supported without using any special securing members, and the number of part items can be reduced, together with that of procedures for installation, and the supporting device can easily be mounted.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support device for an outer wall panel attached to a structural frame of a building in a curtain wall structure building.

[0002]

2. Description of the Related Art In a building having a curtain wall structure, an outer wall panel to be attached to a structural body such as a beam may be attached to the beam or the like in a suspended manner so as to cope with interlayer displacement of the wall body. Has been. In this case, the lower end portion of the outer wall panel is relatively loosely fixed by bolts or the like so that it can be prevented from swinging in the horizontal direction.

[0003]

As described above, it is necessary to fix the lower end portion of the outer wall panel whose upper end portion is suspended and supported to the extent that swinging can be prevented, but in the past, this fixing is special. However, the number of parts is increased and the number of mounting steps is increased.

The present invention solves the above drawbacks of the prior art and, as described above, in the case where the upper end of the outer wall panel is suspended from a structural body such as a beam, the lower end of the outer wall panel is The purpose of the present invention is to enable the attachment without using the supporting member.

[0005]

In order to solve the above-mentioned problems, according to the present invention, a frame of an outer wall panel is arranged below a supporting member projecting outward from a structural body such as a beam,
In a case where the outer wall panel is suspended and supported by bolts inserted into the frame and the supporting member from below, a pin portion integrally formed at the tip of the bolt is inserted into a positioning hole at the lower end of the outer wall panel above. Is characterized by.

[0006]

[Operation] When attaching the outer wall panel, by inserting it into the pin portion at the tip of the outer wall panel fixing bolt that is previously attached to the lower side of the outer wall panel, insert it into the pin insertion hole at the lower end of the outer wall panel on the upper side to be attached The lower end portion can be attached without using a member.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a rear view of an outer wall panel according to the present invention. (2) is a panel body made of a PC board, and the left and right sides made of grooved steel are formed on the back side of the panel body (2). A frame (5) formed in a rectangular shape by a pair of vertical frames (3) and (3) and a pair of upper and lower horizontal frames (4) and (4) also made of channel steel is integrally attached. The upper end of the panel body (2) projects above the horizontal frame (4) on the upper side. Then, at the left and right ends of the upper horizontal frame (4), one end of the support plates (6) (6) is attached by vertical bolts (7) (7) inserted into the horizontal frame (4). Pre-installed. As shown in FIG. 6, the vertical bolt (7) is inserted from below into a bolt hole formed in the web of the lateral frame (4), and its tip is attached to the bolt hole of the support plate (6). When the support plate (6) is attached to the beam (10) side by the nut (9) screwed into the bolt (7) at the upper side of the frame (5), it is inserted through the frame (5). The entire outer wall panel (1) is supported in a suspended manner.

FIG. 6 (11) is a gap holding metal fitting made of an elastic metal plate bent in a U shape when viewed from the side,
The notch portions formed in the upper and lower pieces of the holding metal fitting (11) are fitted to the bolts (7) between the support plate (6) and the upper and lower horizontal frames (4), and the support plate (6) is fixed to a predetermined position. It is held in advance at the height position. In addition, this holding bracket (1
Item 1) is used to roughly maintain the height when carrying the product to the site and is removed after installation.

As shown in FIG. 2, the supporting plate (6) has an elongated hole (13) elongated in the longitudinal direction at the tip end side in the state of being attached to the frame (5). As indicated by the chain double-dashed line, it is held along the upper surface of the upper horizontal frame (4) so that it does not project further outward than the frame (5) from the time it is installed in the factory until it is brought into the field. Has been done. In this case, the width of the support plate (6) is smaller than the width of the horizontal frame (4), so that the support plate (6) is carried in while being accommodated within the width of the horizontal frame (4).

FIG. 3 and subsequent figures show the method of mounting the support plate (6) on the beam (16) side in the order of construction. First, as shown in FIG. 3, the support plate (6)
, And then pulling it out so that it projects in the direction of the beam (10), and then its tip is attached to the upper flange (15) of the beam (10).
The bolt hole (13)
To the bolt hole (16) previously formed in the upper flange (15) of the beam (16), and in this state, the mounting bolt (17) is inserted from the lower side and the nut screwed to the tip thereof. Install by tightening (18). At this time, the support plate (6), that is, the outer wall panel (1) is moved inward and outward within the range of the length of the elongated hole (13) to adjust the entrance and exit of the inside and outside. Further, as shown in FIG. 5, the support plate (6)
While rotating in the left-right direction with the bolt (17) on the beam (10) side as a fulcrum, the position of the outer-wall panel (1) in the left-right direction is adjusted, whereby the width of the left and right vertical joints is adjusted. Further, the vertical adjustment of the outer wall panel (1) is performed by nuts (9) screwed into the bolts (7) on the outer wall panel (1) side.
Rotate and adjust, and when the correct height is determined, remove the holding metal fitting (11).

A positioning pin portion (20) is integrally projectingly provided on the upper end of the bolt (7) on the outer wall panel (1) side, and the pin portion (20) is provided on the outer wall panel (1).
Is inserted into the positioning hole (21) formed in the lower horizontal frame (4) of the outer wall panel (1) installed on the upper side of the outer wall panel (1), whereby the outer wall panel (1) on the upper side is positioned and shaken in the horizontal direction. I try to prevent it.

[0012]

As described above, according to the present invention, the special fixing member is used only by inserting the pin portion at the tip of the bolt fixing the lower outer wall panel into the pin insertion hole at the lower end of the outer wall panel. Moreover, the lower end can be supported, and the number of parts and the number of mounting steps can be reduced accordingly. Of course, by supporting the lower end of the outer wall panel before fixing the upper end, the panel is positioned, and the effect of facilitating the attachment work of the upper end can be obtained.
