Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of manufacturing a PC board with a large ceramic plate which serves as an outer wall of a concrete building and an anchor metal piece used therefor. It was done like this.

[0002]

2. Description of the Related Art When mounting tile pieces on the outer wall of a building,
Conventionally, it has been carried out by a wet attachment method. In that case, mortar or the like is applied to the tiled wall surface and the tile pieces are pressure-bonded to the surface. However, when the tile pieces become large, if the tiles are simply attached to the tiled wall surface, the mortar layer will be displaced due to the weight of the tiles, and the displacement will gradually increase and the tile pieces will fall off. Also, since the tile pieces and the mortar layer have different coefficients of thermal expansion, gaps are created due to the temperature difference between day and night, or summer and winter, and rainwater, etc. penetrates into the back side of the tile pieces for a long time and the water freezes. Also, the tile pieces are likely to peel off due to weathering for a long time. For this reason, it has been proposed that a metal wire be stretched in the mortar layer and the back surface projection of the tile piece be hooked on the metal wire to prevent peeling and falling of the tile (Japanese Patent Publication No. 3-36380). Bulletin).
As an anchor metal for fixing the tile to the wall surface, as described in Japanese Utility Model Publication No. 2-29126,
There is known an anchor metal fitting in which a foot plate having an inclined push plate is pushed by tightening a bolt nut to push a claw piece outward and the claw piece is locked in a hooking hole of a tile.

[0003]

In the above prior art, the tile piece is hooked with the metal wire. However, when the back surface protrusion of the tile piece is hooked with the metal wire during construction, the metal wire is buried in the mortar. It was difficult to work because I could not see it. Further, the metal wire is only engaged with the recess of the projection on the back surface of the mortar, and the projection of the tile piece may be disengaged from the metal wire due to vibration or the like. Therefore, if a large ceramic plate is used as the tile piece in the above, it seems that peeling and dropping cannot be completely prevented. In addition, when fixing the nail piece to the hooking hole of the tile by tightening the bolt and nut, when fixing it to the concrete wall, it must be further fixed through the connecting metal fitting, and when locking it to the tile Since it is necessary to tighten bolts and nuts on the tiles, the work of locking the tiles is a laborious work, which is not desirable.

Therefore, the present invention enables even a large load such as a large ceramic plate to follow out-of-plane displacement such as expansion, contraction change, vibration, etc. due to temperature when mounted on a concrete PC plate. The purpose is to reliably prevent peeling and dropping of plates. Another object of the present invention is to make it possible to easily attach an anchor metal piece to a large-sized ceramic plate and to embed it in a concrete plate so as to be directly fixed thereto.

[0005]

In order to achieve the above object, the method for manufacturing a PC board with a large ceramic plate according to the present invention achieves the above object. After locking both ends of the plate and applying a cushioning material to the back surface of the large ceramic plate, the back surface of the large ceramic plate is placed horizontally and the concrete plate is placed on the large ceramic plate to manufacture a PC plate. I did it. In the anchor metal fitting of the present invention, the central protrusion of a substantially W-shaped spring plate is sandwiched between two metal plates, the protruding side of the spring plate is covered with a box, and both ends of the strip plate are held outwardly inclined. The top of the center of the metal object is stacked on the ceiling surface of the box, and the bolt extends from the holding metal object to the outer metal plate of the spring plate to screw it into the metal plate. So that it can be changed.

[0006]

In the above anchor metal, both ends of the W-shaped spring plate are narrowed by tightening the bolts at first, and both ends are inserted into the C-shaped groove of the large ceramic plate, and the bolts are loosened to loosen the spring plate. Both ends are expanded by the spring force and are locked in the V-shaped groove. After that, when the concrete is poured, the spring plate is covered with the box body, so that the spring plate is not covered with the concrete and the spring force of the spring plate is maintained even after the concrete is hardened. In addition, since the cushioning material is interposed between the large ceramic plate and the concrete plate, and the spring plate is provided on the anchor metal fitting connecting the large ceramic plate and the concrete plate, the difference in thermal expansion and the vibration. The out-of-plane displacement due to is absorbed and the large ceramic plate does not peel off from the concrete plate.

[0007]

EXAMPLE First, an example of the anchor metal article of the present invention will be described with reference to FIGS. Pads 2a and 2b are provided on both sides of the top of the spring plate 1 gently bent into a substantially W shape,
As will be described later, both ends of the spring plate 1 are narrowed by tightening the space between the two metal plates 2a, 2b with bolts 3. The pad 2a is applied to the valley of the top, and the pad 2b larger than the pad 2a is applied to the two peaks of the spring plate 1. The top side of the leaf spring plate 1 is 1
One surface is covered with an open box body 4 so that the spring plate 1 cannot be embedded in concrete 12 described later.

A holding hardware 5 arranged on the ceiling plate of the box body 4.
Has both ends of the strip slanted outward, and the central top of the strip is superposed on the box body 4. The stacking order in this state is as follows: one pad 2a, spring plate 1, the other pad 2b,
The box 4 and the holding metal 5 are arranged in this order, and the bolt 3 penetrates them, and the bolt 3 can be screwed and tightened to the pad 2a that also serves as a nut. By tightening the bolts 3, the space between the tops of the spring plates 1 is contracted, so the spring plates 1
2A is narrowed as shown in FIG. 2A, and then the bolt 3 is loosened so that both ends of the spring plate 1 are widened as shown in FIG. 2B. That is, in FIG. 2, there is a relationship of _{1 1} <l ₂ and h ₁ <h ₂ . Further, the ceiling plate of the box body 4 may be provided with the function of the pad 2b without providing the pad 2b.

Next, a method of manufacturing a PC board with a large-sized ceramic board of the present invention using the above anchor metal will be described with reference to FIGS. On the back surface of the large-sized ceramic plate 10, for example, grooves 11 for fixing anchor metal pieces are provided at appropriate intervals as shown in FIG. The groove 11 is formed in a V-shaped cross section as shown in FIG. The large-sized ceramic plate 10 is one that has been subjected to various color printing and is fired. For example, the size of the plane is 900 × 1200 to 2500 mm, which is considerably heavy.

Insert both ends of the spring plate 1 of the anchor metal into the respective grooves 11 on the back surface of the large ceramic plate 10 and then the bolt 3
Is loosened and both ends of the spring plate 1 are widened to abut against the inner wall of the groove 11 to be locked. In this state, the opening peripheral edge of the box body 4 of the anchor metal is in contact with the back surface of the large-sized ceramic plate 10. Further, a cushioning material 6 such as silica sand is applied to the back surface of the large-sized ceramic plate 10 so that the expansion difference and vibration between the large-sized ceramic plate 10 and the concrete 12 described later can be absorbed.

Then, the back surface of the large ceramic plate 10 to which the anchor metal 2 is locked is placed horizontally with the back surface facing upward, a concrete form is provided around the large ceramic plate 10, and concrete is placed on the large ceramic plate 10. .. At the time of this concrete pouring, since the spring plate 1 of the anchor metal is covered with the box body 4, the spring plate 1 is not buried in the concrete 12, and the spring plate 1 is kept in a state having a spring force. Absorbs vibration, thermal expansion difference, etc. between the large ceramic plate 10 and a concrete plate 12a described later.

Further, after the concrete is hardened, the mold is removed to complete a PC board with a large ceramic board. In this state, since the outwardly sloping inclined portion of the holding hardware 5 of the anchor metal is embedded in the concrete plate 12a, the large ceramic plate 10 and the concrete plate 12a are integrally fixed, and the large ceramic plate is also fixed. The back surface of 10 and the concrete plate are connected by the spring plate 1, and the spring plate 1 absorbs the difference in thermal expansion and vibration.

[0013]

According to the present invention, since a large-sized and large-sized large-sized ceramic plate is fixed to the concrete plate by an anchor metal, even if a PC plate with a large-sized ceramic plate is installed on the outer wall of a building, the large-sized ceramic plate is It does not peel off and fall. In addition, since the anchor hardware is attached to the large ceramic plate by loosening the bolts and then the concrete is placed with the surface of the large ceramic plate facing down, the large ceramic plate can be easily and easily manufactured without damaging the outer wall. It can be applied to a member, a balcony handrail member, etc. and can be made excellent in design. Furthermore, since a cushioning material is interposed between the large ceramic plate and the concrete plate, and a spring plate of the anchor metal is also interposed, the thermal expansion difference due to temperature change and vibration are absorbed, and the large ceramic plate is damaged, It does not peel off.
