Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a tile panel in which a large number of tiles are fixed in a predetermined arrangement to the surface of a substrate made of fiber-reinforced cement such as glass fiber-reinforced cement or asbestos cement.
An object of the present invention is to provide a tile panel and a washer for fixing the panel, which are convenient when fixing to a support member such as an angle member or a wooden pillar using a fixing member such as a nut or a wood screw.

Traditionally, tile panels have been made by pasting a large number of tiles onto the surface of a board such as a plywood or iron plate, but as mentioned above, this type of panel requires pasting each tile onto the board one by one. In order to avoid this troublesome work, recent methods have mainly been used to form concrete walls by aligning and fixing a large number of tiles in the desired arrangement in advance in the formwork, and pouring concrete on the back side of the group of tiles. A concrete wall with tiles, in other words, a precast concrete plate, is used, in which a large number of tiles are fixed in advance on the surface side of the wall.

However, as mentioned above, this precast concrete board has the drawback that it is extremely heavy because it uses a concrete wall as a substrate, which cannot be overlooked as a construction material. We have developed a tile panel using fiber-reinforced cement as a substrate, which has high mechanical strength, and succeeded in eliminating the major drawbacks of the precast concrete boards mentioned above.

However, this fiber-reinforced cement substrate is easily destroyed if strong force is applied to any part of it, so when a tile panel using this substrate is fixed to an angle lumber, wooden pole, etc. using bolts, nuts, wood screws, etc. , since the weight of the entire tile panel is concentrated at the insertion points of the bolts, wood screws, etc.
It was found that strong stress was applied to this area, and mechanical fatigue caused the substrate to break, loosening the fixation of the tile panel, and possibly causing the tile wall surface to collapse.

This invention mainly solves these problems by:
When fixing the tile panel, the above-mentioned destruction of the fiber-reinforced cement substrate is attempted to be prevented by using fixing members such as bolts, nuts, and wood screws via washers as detailed below. It will become clear below that further advantages are obtained according to the invention.

The present invention will be described below with reference to drawings showing embodiments thereof.

FIG. 1 shows a tile panel 1, the main body of which is a large number of tiles 3a fixed in a predetermined arrangement on the surface of a substrate 2 made of fiber-reinforced cement. A portion of the tile 3a that is not fixed, that is, an unfixed portion 4b of the tile remains at a position corresponding to the fixed portion.

The unfixed portion 4b of this tile is located at an appropriate position for fixing the tile panel 1, for example, 2,0007n7ILX1.
,000. In the case of mTn tile panels, there are 5 locations on both sides in the longitudinal direction at 500mm intervals, and 500mm in the center as well.
They will be set up at equal intervals at 5 locations, for a total of 15 locations.

As will be described later, the unfixed portion 4b of the tile is the area where the tile 3b is attached after the tile panel 1 is fixed to the support member, and therefore the area of one tile 3b or the tile It has an area of multiple equinoxes of 3b and, if necessary, an area including a joint area for filling joints between the tiles after pasting the tiles 3b.

In this embodiment, since the joint portion 5 is already formed around the unbonded portion 4b of the tile, the unbonded portion 4b is
The space required for pasting b is sufficient.

6 in the figure is a washer, and as shown in FIGS. 5 and 6, this washer is placed in the washer side exposed portion of the fixing member at the center of the flange portion 7 which has an area that fits within the unfixed portion 4b of the tile. That is, a recess 8 is formed that has enough space to completely accommodate the bolt head, nut, wood screw head, etc., and the shaft of the fixing member is inserted into the bottom wall of this recess 8. A hole 9 of sufficient size is formed.

As shown in FIG. 1, the washer 6 connects the flange portion 7 to the unattached portion 4b of the tile so that the bottom wall of the recess 8 is located on the back side of the board 2, and also connects the hole 9 to the back side of the board 2. It is opened to the side.

The washer 6 is made not only of metal but also of a suitable material such as hard synthetic resin.

This tile panel 1 is produced by fixing a large number of tiles 3a to a formwork (not shown) in a predetermined arrangement and also fixing washers 6 at required positions, similar to the production of known precast concrete plates. Then, the back side of tile 3a,
By forming a fiber-reinforced cement layer on the back side of the washer 6 and between the tiles 3a, the tiles 3a group and the washer 6 are fixed to the substrate 2 and the necessary joints 5 are formed simultaneously with the composition of the substrate 2. It is convenient to speed up production by attaching tiles 33 and washers 6 to the surface side of a fiber-reinforced cement board prepared in advance using adhesive, and then performing the necessary joint filling. Of course, it may be manufactured.

Note that in order to firmly fix the washer 6 to the board 2, the seventh
As shown in the figure, it is preferable to provide a protrusion 8a for biting into the substrate 2 on the outer surface of the recess 8 of the washer 6.

When fixing the tile panel 1 obtained in this way to a support member such as an angle member, for example, as shown in FIG. Screw the nut 12 onto the exposed end of the angle member 11 side and tighten.

At this time, the entire exposed portion of the bolt 10 on the washer side, ie, the head 10a of the bolt in this example, is completely accommodated in the recess 8 of the washer 6, and therefore does not protrude above the surface of the flange portion 7.

Then, as shown in FIG. 3, a tile 3b coated with adhesive 13 on the back side is adhered to the surface of the flange portion 7 of the washer 6, thereby completing the fixing of the tile panel 1 and the construction of the tile wall surface.

In this way, in order to make the surface of the tile 3b that is pasted later on the same plane as the surface of the other tiles 3a, the surface of the unfixed part 4b of the tile is the same as that of the already fixed part 4a of the tile.
Adhesive 1 is applied to the thickness of the flange portion 7 of the washer 6 compared to the surface of the
It is preferable that the height be lowered by approximately the same amount as the thickness of layer 3.

The bottom wall of the recess 8 of the washer 6 is, for example, as shown in FIG.
Although it may not be exposed on the back surface of the board 2, in this case, it goes without saying that a hole 14 is formed in the board 2 at a position corresponding to the hole 9 of the washer 6, into which a fixing member such as a bolt 10 can be inserted. do not have.

In this invention, as shown in FIGS. 8 and 9, the washer 6 is sometimes used across two adjacent tile panels 1, 1'.

In this case, the unfixed portion 4b of the tile is left on each tile panel 1 and 1' so that it can span over the two adjacent tile panels 1 and 1' with the washer 6 in between. Ru.

In the illustrated case, each edge of both tile panels 1, 1' is in contact with the outer surface of the recess 8 of the washer 6, so that
The unfixed portion 4b is attached to each substrate 2 of both tile panels 1 and 1'.
It consists of the sum of the area of the edge surface 2' and the surface area of the space separated by the recess 8 of the washer 6, and in this case, the joint area is also added to an integral multiple of the tile 3b (9
It has an area of

In the examples shown in FIGS. 8 and 9, the washer 6 may be fixed to any of the tile panels in advance, or may not be fixed to any of them.

In the latter case, a space of the required area (
Sandwich the washer 6 between the edges of the tile panels 1 and 1' with the tile panels 1 and 1' left in place (the part where the tile 3a is not fixed), and then use fixing members such as bolts and nuts 1-10 and 12 as shown in the figure. It is fixed to the support member 11.

If the substrate of the tile panel is not protected by the washer of the present invention, the insertion hole of the fixing member in the substrate will expand due to the weight of the tile, and the fixing position of the tile panel will shift downward. There was a risk of an accident such as the board being destroyed, but according to the present invention, the insertion hole of the fixing member in the board is protected by the hole of the washer, so there is no risk of such an accident occurring. Furthermore, when tightening the fixing member, the force is diffused by the flange portion of the washer, so there is no risk of concentrated stress being applied to the fixing portion of the tile panel.

Furthermore, according to this invention, since the tile panel is fixed to the supporting member and then the tile is attached to the surface of this fixed part, the fixing member etc. do not appear on the tile wall surface, resulting in a beautiful appearance. It brings about the effect of
