Description

The present invention relates to a mounting structure for a relatively heavy outer wall panel such as stone, glass, or large tile.

[Conventional technology]

The outer wall curtain wall in recent years is relatively often finished with a relatively heavy material such as marble or large tile.

Most of the outer wall curtain walls of this type have an outer wall panel such as marble or large tiles bonded to the outside of the PC board in advance.
This PC board is constructed by bolting it to the structure of the building.

[Problems to be Solved by the Invention]

However, with such a configuration, depending on the outer wall panel adhered to the outdoor side of the PC board, if the thermal expansion coefficient of the PC board and the outer wall panel is significantly different, the PC board and the outer wall panel expand due to solar heat, The entire panel may be warped, the outer wall panel may be cracked or peeled off.

In many cases, the gap between the panels is filled with a sealing material for the purpose of preventing rainwater from entering, but if the sealing material is improper or the construction is insufficient, the sealing material may There was a risk that the surface of the outer wall panel would become dirty.

The present invention was developed to solve the above-mentioned conventional problems, and it is possible to improve the seismic resistance of the building by reducing the weight of the outer wall and warp of the panel due to thermal expansion, cracking of the outer wall panel, peeling and An object of the present invention is to provide a mounting structure for an outer wall panel, which can prevent the outer wall panel from being soiled substantially completely.

[Means for Solving the Problems]

The present invention relates to a mounting structure for a relatively heavy outer wall panel such as stone, glass, or a large tile, and has a lattice shape composed of a vertical frame member 2 and a horizontal frame member 3 between upper and lower slabs 1 and 1 of a building. The base frame 4 is assembled, a rustproof thin iron plate 5 is attached to the outdoor side of the base frame 4, a plurality of mounting holes 6 are formed in the vertical frame member 2 and the horizontal frame member 3, and the outdoor side of the base frame 4 is assembled. A plurality of outer wall panels 8 are attached to the outer wall panel 8, and anchor bolts 9 projecting inward from the upper and lower edge ends in which the base ends are inserted and fixed in deep holes in the vertical direction of the outer wall panels 8.
The above object is achieved by projecting the anchor bolt 9 through the mounting hole 6 and mounting the outer wall panel 8 by screwing a fixing nut into the male screw portion of the penetrating portion.

〔Example〕

 The present invention will be described below with reference to an embodiment shown in the drawings.

A base frame 4 is assembled by framing a plurality of vertical frame members 2 and horizontal frame members 3 made of lightweight chevron between the upper and lower slabs 1 and 1 of the building. It is fixed to 1 by bolting or welding.

The vertical frame member 2 and the horizontal frame member 3 are integrally assembled by welding or bolting.

Further, a rustproof thin iron plate 5 is attached to the outside of the base frame 4 by welding. The indoor surface of the rustproof thin iron plate 5 is coated with a fireproof coating.

Mounting holes 6, 6 are continuously formed in the vertical frame member 2 and the horizontal frame member 3 of the base frame 4 and the rustproof thin iron plate 5.

Further, a waterproof packing 7 is interposed in the peripheral portion of the mounting hole 6 between the vertical frame member 2 and the horizontal frame member 3 and the rustproof thin iron plate 5 so that rainwater does not enter the indoor side due to the periphery of the mounting hole 6. Have been taken into account.

The required number of base frames 4 thus constructed are lined up in the vertical and horizontal directions according to the size of the wall surface to be constructed, and fixed to the upper and lower slabs 1 and 1 by fasteners (not shown). There is.

In addition, waterproof packing is interposed between the vertical frame members 4 and 4 and between the vertical frame members 2 and 2 and between the horizontal frame members 3 and 3 between the left and right substrate frames 4 and 4 (illustration is omitted), and rainwater is leaked from this portion. Considered to prevent infiltration.

Outside wall panels 8 made of stone, glass or large tiles are attached to the outside of the rustproof thin iron plate 5 of the base frame 4.

Anchor bolts 9, 9 projecting toward the indoor side are attached to the upper and lower edge portions of the outer wall panel 8.

The anchor bolt 9 is formed with a deep dowel hole 10 in the vertical direction of the outer wall panel 8 at the upper and lower edge portions of the outer wall panel 8, the base end portion of the anchor bolt 9 is inserted into the dowel hole 10, and the peripheral portion thereof is made of mortar. It is fixed by filling a filler 11 such as resin cement mortar.

The outer wall panels 8 and 8 have anchor bolts 9 and 9 attached to the vertical frame member 2 and the horizontal frame member 3 of the base frame 4, respectively.
6 and a washer 12 on the male screw portion of the penetrating portion.
Are attached, and then the fixing nuts 13 are screwed to be fixed to the base frame 4, respectively.

The outer wall panels 8 and 8 are provided between the base frame 4 and the outer wall panel 8.
Wedges 14, 14 are interposed for the purpose of adjusting the outdoor side surface so that it is flush with the outside surface.

A wedge 14 is interposed between the base frame 4 and the outer wall panel 8 to form an equal pressure space 15 between the base frame 4 and the outer wall panel 8. The equal pressure space 15 prevents rainwater from further admitting to the indoor side. The effect of being unable to penetrate into

Further, by circulating the outside air in the isobaric space 15, it is possible to prevent dew condensation water from being generated in this portion.

〔The invention's effect〕

Since the present invention is configured as described above, it has the following effects.

Since the outer wall panel is not attached to the PC board but is attached to the base frame made of lightweight chevron steel, the weight of the wall body and the entire building can be reduced, and the earthquake resistance can be improved.

Also, the outer wall panel may warp or crack due to thermal expansion,
Or, there is almost no worry that it will come off.

In addition, a rustproof thin iron plate is attached to the entire base frame, and since this rustproof thin iron plate has a function of preventing intrusion of rainwater, it is necessary to intentionally fill the seal material between the outer wall panel and the outer wall panel. Therefore, the surface of the outer wall panel is not contaminated by the sealing material.

Also, the sealing work can be omitted.

In particular, the anchor bolts of the outer wall panel are rustproof thin iron plates, vertical frame members, since they protrude from the upper and lower edge ends of the outer wall panel into which the base end portions are inserted and fixed in deep holes at the upper and lower edge ends of the outer wall panel to the indoor side. It can be easily inserted by checking the position of the mounting hole of the horizontal frame member,
Good workability.
