Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a mounting structure for an exterior body forming the exterior surface of a curtain wall.

(Prior art) The structure of curtain walls that form the outer peripheral surface of buildings is mainly constructed by attaching decorative board materials such as ceramic tiles, glass tiles, and stone to concrete or metal frame substrates using various adhesives. .

(Problem to be solved by the invention) In this curtain wall, under high-temperature environments such as external solar heat or fires, the decorative board material and the substrate move away from the substrate due to the difference in expansion and contraction displacement between the decorative board material and the substrate. They may fall off, or cracks may occur in the decorative board due to external stress such as earthquakes. In particular, when the decorative plate material is formed as a large thin plate material, the above-mentioned cracking and falling off are noticeable.

For this reason, a method is used to securely fix the decorative board on the surface of the board using special binders, adhesives, and mounting jigs, but the weight of the curtain wall itself becomes large and it takes a lot of time to transport and install it. The length did not require much labor, and the installation accuracy decreased, requiring extra work such as rework.

(Means for solving the problem) The present invention was devised to solve the above problem, and it improves the installation accuracy by pasting a frame material around the back surface of the decorative board, and also An asbestos cement board, calcium silicate board, fiber-containing inorganic board, etc. is attached to the back of the decorative board surrounded by wood to reinforce the back and form an exterior body that will not fall off or peel off. It is characterized by being hung in a hanging groove to prevent it from falling off or peeling off from the board, thereby achieving double prevention of falling off and peeling off as a whole, and by using a supporting metal fitting to further ensure complete fixation. It is.

(Example) Hereinafter, the curtain wall exterior mounting structure of the present invention will be described in detail based on the drawings.

FIGS. 1 to 3 are diagrams illustrating one exterior body attached to the surface of a substrate.

FIG. 1 is a front view of the exterior body 1, and FIG. 2 is a rear view thereof.

The exterior body 1 has an upper frame 12, a lower frame 13, and both side frames 14, 14 attached to the four circumferences of the back surface of a decorative board 11, respectively. These frame materials 12, 13, 14, 1
An asbestos cement board 15 is pasted on the back surface of the decorative board 11 surrounded by 4. The upper frame material 12, the lower frame material 13, and the side frame materials 14, 14 are made of weather-resistant drawn aluminum material, resin material, or the like, and each is adhered to the back surface of the decorative board 11 via an adhesive 17. As the adhesive material 17, a material having high elasticity and cushioning properties, such as SBR resin mortar, is used.

Also, on the back side of the enclosed decorative board is an asbestos cement board 1.
5 is bonded with adhesive 17 as described above, and connected to each frame member 12, 13, 14, 14 via presser metal fittings 18, 18, . . . having a substantially Z-shaped cross section.

Further, as shown in FIG. 3, which is a cross-sectional view taken along the line A-A in FIG. L
The decorative board 11 itself is supported and held by screwing the holding fittings n in the shape of a letter to the lower frame material 13 and the upper frame material 12, respectively.

Furthermore, hanging pieces 19, 19 are formed downwardly on the upper frame member 12 and the lower frame member 13, respectively, in the longitudinal direction.

The construction of fixing the exterior body 1 having the above structure to the concrete substrate P will be explained with reference to the schematic side view of FIG. 4.

First, the receiving fittings 2, 2, . . . are fixed at predetermined intervals on the substrate P at predetermined positions (the figure shows only one receiving fitting 2). The receiving fitting 2 has a substantially square cross-section with mounting sides 21, 21 and a body side 22 provided therebetween. Waistline 2
Side sides 23, 23 extend upward from 2 to form an upper hooking groove 24 and a lower hooking groove 25 with an upper opening.

The lower hooking pieces 19 of the exterior body 1 disposed on the upper stage are hooked to the upper fixing groove 24, and the upper hooking pieces 19 of the exterior body 1 disposed on the lower stage are hooked to the lower hooking groove 25, respectively. It is hung up.

As described above, the horizontal joints Q are formed and the exterior bodies 1, 1 are attached to the upper and lower stages.

In addition, in order to ensure that each of the hanging pieces 19 and 19 are connected to the upper hanging groove 24 and the lower hanging groove 25, highly elastic adhesive material 3 may be filled as necessary. It is possible. Furthermore, by attaching an angled floating prevention metal fitting 26, floating of the exterior body can be prevented.

FIG. 5 is a schematic cross-sectional view showing a state in which the exterior bodies 1, 1, .

Further, FIG. 6 is a plan sectional view showing a state in which the exterior bodies 1, 1 which are adjacent in the lateral direction are attached.

A vertical joint R passes through the exterior bodies 1 and 1 adjacent in the horizontal direction, and the side frame material 1 is pasted on the back surface of the decorative board 11.
A slat plate 4 is disposed between 4 and 14 as necessary.

FIG. 7 is a partially cutaway perspective view showing a state in which the exterior bodies 1, 1, .

As shown in this figure, the exterior body 1 itself has a decorative board 11
Frame materials 12, 1 are attached to the four circumferences of the back surface of the
3, 14, and 14 are pasted, the adhesion of each frame material to the decorative board 11 is sufficient, and the support metal fittings m, m
The decorative board 11 can be reliably supported and held by the upper frame member 12 and the lower frame member 13 via the holding fittings n, n, etc.

Furthermore, an asbestos cement board 15 is adhered to the back surface of the decorative board 11 surrounded by each of the frame members 12, 13, 14, 14 with an adhesive 17, and holding fittings 18, 18...
Since it is connected to each of the frame members 12, 13, 14, and 14, the decorative board 11 itself is backed and reinforced, and it is completely fixed to the frame members 12, 13 having the hanging pieces 19, 19.

That is, if the exterior body 1 is hooked to the receiving metal fitting 2 attached to the surface of the board P, it will not fall off. Therefore, the decorative board 11 itself is doubly prevented from falling off and peeling off.

As shown in the schematic plan view in FIG. 8, reinforcing through frames 5, 5 are installed along the side frames 14, 14 in order to strengthen the connection between the vertically adjacent exterior bodies.
It can also be fixed and made into a panel.

In addition, as shown in the side cross-sectional schematic diagram of FIG. 9, the upper frame 1
2 and along the lower frame 13 are reinforced through frames 6, 6.
It is also possible to fix a plurality of exterior bodies 1, 1 and join them laterally to form a panel.

Therefore, the exterior mounting structure of the present invention can be attached to a board at the curtain wall construction site, or can be pre-attached to a PC concrete board, etc. on a factory production line.

Furthermore, it is also possible to form a unit by attaching the exterior body to a lightweight steel frame material assembled to a predetermined size, a so-called metal frame panel.

(Effects) As explained above, according to the exterior body mounting structure of the present invention, the exterior body itself is formed by pasting the frame material around the back surface of the decorative board. Installation is simple and can be performed with high precision.

Furthermore, since the decorative board is joined to each frame material and the asbestos cement board via an adhesive, the backing is completely reinforced and neither cracks nor peeling occurs.

Furthermore, since the decorative laminate itself is supported and held through the supporting metal fittings and the holding metal fittings, it is doubly prevented from falling off and peeling off, making the curtain wall exterior mounting structure extremely safe.
