Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a mounting structure for relatively heavy exterior wall panels such as stone, glass, large tile, etc.

[Prior Art] In recent years, relatively many exterior curtain walls are finished with relatively heavy materials such as marble and large tiles.

Most of these types of exterior curtain walls are made by bonding exterior wall panels such as marble or large tiles to the outdoor side of the PC board in advance.
This PC board is constructed by bolting or the like to the building structure.

[Problems to be Solved by the Invention] However, with this configuration, depending on the exterior wall panel that is adhered to the outdoor side of the PC half-wall, if the coefficient of thermal expansion between the PC board and the exterior wall panel is significantly different, the PC board and the exterior wall panel may differ significantly. Exterior wall panels may expand when exposed to solar heat, causing the entire panel to warp, crack, or peel off.

In addition, in many cases, sealing material is filled in the gaps between panels to prevent rainwater from entering, but if the sealing material is inappropriate or poorly installed, seal H may cause damage. There was also the risk that the surface of the exterior wall panels would get dirty.

This invention was developed in order to solve the above-mentioned conventional problems, and it is possible to improve the earthquake resistance of buildings by reducing the weight of the outer wall, and to prevent warping of panels due to thermal expansion, cracking, peeling, and peeling of outer wall panels. The installation of exterior wall panels is intended to provide a structure that can substantially completely prevent soiling of the exterior wall panels.

[Means for Solving the Problems] The present invention relates to a structure in which external wall panels, which are extremely heavy, such as stone, glass, or large tiles, are installed. A lattice-shaped base frame 4 is assembled from the member 2 and the horizontal frame member 3, a rust-proof thin iron plate 5 is attached to the outdoor side of the base frame 4, and a plurality of pieces are attached to the vertical frame keys 2 and the horizontal frame member 3. A mounting hole 6 is formed, and a plurality of external wall panels 8 are attached to the outdoor side of the base frame 4,
Anchor bolts 9 protruding toward the indoor side are provided on the upper and lower edges of the outer wall panel 8, and the anchor bolts 9 are inserted through the mounting holes 6, and a fixing nand is screwed into the male threaded portion of the penetrating portion. The above objective is achieved by attaching the outer wall panel 8.

〔Example] The present invention will be explained below with reference to an illustrated embodiment.

A base frame 4 is assembled between the upper and lower slabs 1.1 of the building by framing a plurality of vertical frame members 2 made of lightweight angle iron and horizontal frame members 43 in a lattice shape, and the base frame 4 is assembled between the upper and lower slabs. 1.1 is fixed by bolting or welding.

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

Further, a rust-proof thin iron plate 5 is attached to the outdoor side of the base frame Mi4 by welding. A GJ fireproof coating is applied to the indoor surface of the rust-proof thin iron plate 5.

Attachment holes 6.6 are continuously formed in the vertical frame member 2 and horizontal frame member 3 of the base frame 4 and in the antirust thin iron plate 5.

Further, a waterproof packing 7 is interposed around the hole 6 between the vertical frame member 2 and the horizontal frame member 3 and the rust-proof thin iron plate 5.
Consideration is given to prevent rainwater from entering the indoor side from the vicinity of the hole 6.

The base frames 4 configured in this way are installed in the required number according to the size of the wall surface to be constructed, arranged in vertical and horizontal directions, and are each fixed to the upper and lower slabs 1.1 with fasteners (not shown). There is.

In addition, waterproof gaskets (not shown) are interposed between the vertical frame members 2.2 and 3.3 between the upper and lower base frames 4.4 and between the left and right base frames 4.4, and rainwater is prevented from flowing through these parts. Designed to prevent infiltration.

An exterior wall panel 8.8 made of stone, glass, large tiles, etc. is installed on the outdoor side of the rust-proof thin iron plate 5 of the base frame 4.
I'm being kicked.

Anchor bolts 9.9 are attached to the upper and lower edges of the outer wall panel 8 and project toward the indoor side.

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

Then, the anchor bolts 9.9 of each outer wall panel 8.8 are passed through the mounting holes 6.6 of the vertical frame members 2 and horizontal frame members 3 of the base frame iFU 4, and the washers 12 are attached to the male threaded portions of the penetration parts. , and are then fixed to the base frame 4 by screwing together the fixing nuts 13.

An outer wall panel 8.8 is provided between the base frame 4 and the outer wall panel 8.
Adjust this so that the outdoor side of the
A cutout 14.14 is interposed for the purpose of circumference.

Furthermore, by interposing the pattern 14 between the base frame 4 and the outer wall panel 8, an equal pressure space 15 is created between the base frame 4 and the outer wall panel 8, and this equal pressure space 15 prevents rainwater from reaching the indoor side. This has the effect of preventing infiltration.

Furthermore, by circulating outside air within the equal pressure space 15, it is possible to prevent dew condensation from forming in this area.

[Effects of the Invention] Since the present invention has the above configuration, it has the following effects.

The exterior wall panels are not attached to PC boards, but are attached to the base framework assembled from lightweight angle steel, making it possible to reduce the weight of the walls and, by extension, the weight of the entire building, improving earthquake resistance.

Also, external wall panels may warp or crack due to thermal expansion.
There is also almost no need to worry about it peeling off.

In addition, a rust-proof thin iron plate is applied to the entire base frame, and since this rust-proof thin iron plate has the function of preventing rainwater from entering, a sealant is deliberately placed between the outer wall panels. There is no need to fill the sealant with sealant, and therefore the surface of the exterior wall panel will not be contaminated by the sealant.

Moreover, sealing work can be omitted.

Furthermore, since the anchor bolts of the exterior wall panel are attached not to the back side of the exterior wall panel but to the upper and lower edges that can be easily reached, attachment of the anchor bolts can be easily performed.
