Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a structure for attaching a decorative laminate to the surface of a curtain wall that forms the exterior wall surface and interior wall surface of a building.

(Prior art) A curtain wall is made by using a concrete board as a substrate and attaching a decorative board to the surface of the board.A decorative board such as tiles is attached to the concrete surface using mortar as an inorganic binder or an organic adhesive. It is formed by the so-called wet method. Moreover, since multiple decorative boards are placed on the surface of a concrete board to form joints at predetermined intervals,
The work is mainly done by hand-laid work by specialized craftsmen such as tile workers.

(Problems to be Solved by the Invention) Many problems have been pointed out in the past in such curtain walls.

For example, since the substrate is made of concrete and the decorative board is attached via an adhesive, it requires hardening and curing time to reach a predetermined strength.

Furthermore, when a displacement occurs in the concrete substrate, the decorative board cannot absorb the displacement, and the decorative board itself receives local stress and cracks occur. In particular, if the decorative board is rapidly heated and expanded, such as in the event of a fire, it may easily peel off or fall off from the concrete base.

Furthermore, since multiple decorative boards are pasted one by one at predetermined intervals, the accuracy of the vertical and horizontal joints varies depending on the skill level of the craftsman, making it impossible to maintain a constant decorative quality accuracy on the surface.
Moreover, the weight and bulk of the curtain wall itself are large, requiring much labor to transport and erect.

(Means for Solving the Problems) The present invention was devised to solve the above-mentioned problems, and involves attaching a decorative board to a substrate made of concrete or a metal frame using the so-called dry method.

That is, a receiving metal fitting having a horizontally elongated groove formed approximately in the center is attached to the base plate, and a hook portion having a T-shaped cross section formed by the face plate and the support piece is hooked to the receiving metal fitting.

Then, the hook formed at the tip of the support piece is hooked into the horizontal groove of the receiving bracket, and the upper edge of the decorative board placed on the lower level is held by the face material, and the lower edge of the decorative plate placed on the upper level is held. It is supported by the support piece. This makes it possible to efficiently attach a plurality of decorative plates to the surface of the substrate.

(Example) The decorative panel mounting structure of a curtain wall of the present invention will be described in detail below based on one drawing.

FIG. 1 is a partially omitted perspective view for explaining the receiving metal fitting 1 and the latch fitting 2. FIG.

The receiving metal fitting 1 is an elongated metal fitting that is attached across the board in the lateral direction. Mounting sides B and t provided above and below in the short direction
A horizontally long groove 12 is provided in the center of t, and this horizontally long groove 12 opens outward and has a substantially semicircular cross section. Also horizontal groove 12
A projecting piece 13 is provided along the longitudinal direction of the horizontally long groove 12 on the upper side of the opening. A receiving plate 14 extends outward from the lower side of the opening of the horizontally long groove 12.

The receiving plate 14 supports a latching fitting 2, which will be described later, and is provided with a notch 15 at the location where the latching fitting 2 is hung, thereby fixing the position of the latching fitting 2 and preventing lateral movement. .

Furthermore, two adhesive strips 18 and 17 are provided above and below the horizontally long groove 12 in the longitudinal direction.

On the other hand, the latch 2 has a T-shaped cross section with a face plate 21 and a support piece 22. The zero face plate 21 is formed on an upper side 21a and a lower side 21b with the support piece 22 as a boundary, and its planar shape is as follows. For example, any pattern such as circular, triangular, diamond, etc. can be selected. Further, a hook portion 23 is integrally formed at the tip of the support piece 22. Since this hooking portion 23 is hooked into the horizontally long groove 12 of the receiving metal fitting 1, it has a semicircular shape that is substantially the same shape as the horizontally long groove 12.

FIG. 2 is a schematic side view showing a state in which the above-mentioned receiving metal fitting 1 and latching metal fitting 2 are used to hold the decorative board 3 arranged on the lower stage.

That is, the receiving metal fitting l is attached to a predetermined marked position (not shown) on the board P via screws or the like. Then, the upper end of the back surface of the decorative board 3 is adhered to the adhesive 17 and placed.
' In this state, the latching part 23 of the latching fitting 2 is fitted into the horizontally elongated groove 12. To fit it in, tilt the hook part 23 so that it does not touch the protruding piece 13 of the horizontally long groove 12, and hold the support piece 22 horizontally with the outer circumferential surface of the hook part 23 and the inner circumferential surface of the horizontally long groove 12 in contact with each other. direction (arrow line direction in Figure 2),
Then, the upper end 23a of the latching portion 23 is hooked on the protruding piece 13, and the latching metal fitting 2 is in a state in which it does not come off from the receiving metal fitting l. At this time,
As shown in the schematic side view of FIG. 3, the upper edge of the decorative board 3 is held by the lower side 21b of the face plate 21.

Next, when the lower end piece of the decorative board 4 is placed on the support piece 22, the back surface of the lower end edge of the decorative board 4 is adhered to the adhesive 1B, and the front surface is supported by the upper side 21a.

FIG. 4 is a partially omitted perspective view of a state in which a hook 2 is provided at the joint intersection of adjacent decorative boards 3.3 and 4.4 to hold and support each decorative board 3, 3.4.4. be.

Moreover, FIG. 5(a) is a surface schematic diagram in which a plurality of decorative boards 3, 3, 4, 4, . . . are attached with hooks 2 provided at joint intersections.

Furthermore, as shown in FIG. 5(b), it is also possible to provide the hooks 2, 2 only at the horizontal joints to hold and support the upper and lower decorative boards 3.4, respectively.

(Effects of the Invention) As described above, the curtain wall decorative laminate mounting structure of the present invention has the following effects because each decorative laminate is attached by hooking the latching metal fittings to the receiving metal fittings attached to the board. do.

■The decorative board is attached to the surface of the board using a receiving metal fitting and a latching metal fitting. Since it is a so-called dry method, there is no need for a curing period, etc.
The construction period will be shortened.

■The displacement of the board does not directly affect the decorative board, and the mounting strength is mechanically stable even in cold regions where temperature changes are large.

■Since the structure supports and holds the upper and lower edges of the decorative board, it is possible to reduce the weight of the receiving metal fittings and the hanging metal fittings, making the entire curtain wall lightweight and easy to transport and install.

Furthermore, if the mounting bracket is installed accurately, the vertical and horizontal alignment of the decorative board will be accurate, and so-called vertical and horizontal joints with uniform joint width can be obtained.

Therefore, it is possible to carry out construction of a specified quality without requiring much skill from the craftsmen.
