Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a sealant for tile joints that fills the joints of tiles that are adhered to walls of buildings.

In this specification, the term tile refers not only to a thin plate-shaped fired clay product that is usually attached to the surface of a wall, but also to any thin plate-shaped product made of other materials that is similarly attached to the wall surface. Therefore, ceramic tiles,
This naturally includes not only glass tiles but also thin bricks.

BACKGROUND OF THE INVENTION It is well known that tiles are used to finish walls in order to give buildings a solid appearance. Furthermore, the use of laminar bricks as tiles allows buildings to have the appearance of masonry construction, and has recently been widely used.

Conventional finishing methods using tiles include (1) on-site installation method, (2) tile formwork pre-installation method, and (3) tile pre-installation precast reinforced concrete (PC) board method.

In the conventional on-site installation method, tiles are placed one by one on a base such as mortar using mortar as an adhesive, and after the mortar has hardened, the tiles must be filled with joint mortar. Therefore, it has the disadvantage that it requires skill to finish accurately and neatly, requires a large number of man-hours, and takes time to finish.

According to methods (2) and (3), the tiling work itself is easy, but it is still necessary to fill the joints, resulting in poor workability.

Purpose of the Invention The present invention has been made in consideration of the above points, and
The purpose of this invention is to provide a sealant for tile joints that does not require any subsequent filling work during tiling work.

Another object is to provide a sealant for tile joints that can reliably prevent rainwater from entering.

Summary of the Invention The sealing material according to the present invention is made of an elastic material such as synthetic resin, synthetic rubber, or natural rubber, and is formed into an elongated shape with a width slightly wider than the width of the joint between tiles. The joints are covered by compression fitting, making it possible to seal the joints of tiles without using joint mortar or the like.

Therefore, there are horizontal joints and vertical joints, and the sealant for the horizontal joints uses a long cross-sectional material with fins that can close the joints, and the sealant for the vertical joints uses the same material. Use a cross-sectional shape that has fins that can close the joints and corresponds to the length of the vertical width of the tile.

The above-mentioned vertical joint sealing material has an umbrella part covering the base with at least fins on both ends, so that when it is inserted into the vertical joint, only the umbrella part protrudes to the horizontal joint. When the sealant for horizontal joints is inserted, the umbrella part is held down by the sealant for horizontal joints, completely preventing rainwater from entering from the joint between the sealant for horizontal joints and the sealant for vertical joints. be.

Configuration of the Embodiment FIG. 1 shows a wall structure of a wooden building using an on-site construction method using an embodiment of the present invention. A wooden board 1 is used as a wall base material, and thin bricks 2, 2, .

A wooden board 1 is fixed to a pillar 3, a stud 4, etc. with nails, waterproof paper 5 is pasted on the surface thereof, and supports 7, 7, . . . are attached in parallel to the surface to serve as a wall base. As will be described later, the supports 7 are for attaching the thin bricks 2, and are attached in parallel with each other at a constant interval. The spacing varies depending on the height of the thin bricks 2, and is selected so that a joint of a constant width can be formed between the upper and lower adjacent thin bricks 2, 2.

The cross-sectional shape of the support body 7 is as shown in FIG. 2, and is formed to have a bottom part 7a in contact with the surface of the waterproof paper 5, an upper support piece 7b and a lower support piece 7c formed at both ends of the bottom part 7a. , upper and lower support pieces 7b, 7
c stand up from the bottom 7a so as to spread out from each other. The support body 7 is formed by bending a metal plate such as aluminum, and the support pieces 7b and 7c have elasticity.

The thin brick 2 shown by the dashed line in FIG. 2 is formed into a rectangular plate shape like a normal thin brick,
A notch 2b for fitting and fixing to the support body is provided at the center of the back surface 2a. As shown in the figure, this notch 2b is cut into a dovetail shape that widens as it goes inside from the back surface 2a.
The upper and lower support pieces 7b and 7c of the support body are pressed against the inclined portions 2c and 2c on both sides thereof. That is, the slopes of the slope parts 2c, 2c are formed in accordance with the widening slopes of the support pieces 7b, 7c, and the interval therebetween is made slightly narrower than the distance between both support pieces 7b, 7c, so that the thin brick 2 is attached to the support body. At times, the elasticity of the support pieces 7b, 7c makes it possible to fix the thin brick 2 to the support body. In order to fit and fix the thin brick 2 to the support 7, first, place the lower inclined part 2c against the lower support piece 7c, raise the thin brick 2 upward against the elasticity of the lower inclined part 2c, and then It is sufficient to simply insert the upper support piece 7b into the notch 2b so as to touch it.
As described above, the support pieces 7b and 7c have elasticity and the distance between them is wider than the distance between the sloped parts 2c and 2c of the notch 2b, so the thin brick 2 is fixed to the support body 7.

The thin bricks 2, 2, . . . are sequentially attached to the support 7 as described above. At this time, a certain distance is left between the horizontally adjacent thin bricks 2, 2 to form vertical joints. As mentioned above, a horizontal joint is naturally formed between the upper and lower thin bricks 2, 2.

These joints are filled with the sealant according to this example. The sealing material according to this embodiment is composed of a horizontal joint sealing material 8 and a vertical joint sealing material 9 made of an elastic material such as synthetic resin, synthetic rubber, or natural rubber. In this example, an ethylene propylene copolymer with a hardness of 60 degrees was used.

The cross-sectional shape of the side joint sealing material 8 is as shown in FIG.
and the lateral side surfaces 2 of the thin brick 2 on both sides of the part connected to the bottom part 8a and standing upright from the bottom part.
Fin 8 whose tip at least contacts d and 2e
b, 8b... and a base 8c. The width of the sealant 8 for horizontal joints is made slightly wider than the width of the horizontal joints, so that when the joints are sealed, the fins 8
The tips of b, 8b, . . . are in strong contact with the side surfaces of the thin bricks. Sealing material for side joints 8
is a long object having this cross-sectional shape, and is made by extrusion molding.

On the other hand, the vertical joint sealing material 9 is applied to the base 9 described later.
It is a short piece whose length c is almost the same as the height of the tile, and its cross-sectional shape is as shown in FIG. Since it is short, it can be molded by injection molding, compression molding, or other means. This sealing material 9 has a bottom portion 9a that comes into contact with the waterproof paper 5, similar to the side joint sealing material 8.
and the vertical side surfaces 2f, 2g of the thin bricks 2, 2
The base portion 9c has fins 9b, 9b, . Further, the bottom portion 9a is formed with a notch 9e for straddling the support, as shown in FIG. Since the length of the base portion 9c is approximately equal to the vertical width of the tile 2, when the sealing material 9 for vertical joints is inserted into the vertical joints, the umbrella portion 9d is attached to the horizontal joints as shown in FIGS. 2 and 5. stand out. Although the umbrella portion 9d is continuous with the base 9c and the fins 9b provided on the base in this embodiment, it may not be continuous. A continuous one like in this example has good watertightness.

The cross-sectional shapes of the sealing material 8 for horizontal joints and the sealing material 9 for vertical joints are not limited to those shown in the drawings; they are strongly pressed against the side surfaces of adjacent thin bricks 2 that make up each joint, and there is no gap between the joints. Any structure that does not allow for this is acceptable.

Effects of the Embodiment To form a wall with these, first attach the wooden boards 1 to the pillars 3, studs 4, etc., and after pasting the waterproof paper 5 on the surface, support members 7, 7... are placed at predetermined intervals. Keep it level and install it horizontally. Thereafter, the thin brick 2 is fixed to the support 7 as described above. In fixing this thin brick 2, it is of course possible to use the elasticity of the support pieces 7b, 7c of the support body 7 as described above, but the thin brick It may be inserted into the notch 2b of the brick 2, slid and fixed in a predetermined position.

After fixing the thin brick 2 in this way,
Horizontal joint sealing material 8 according to this example at the joint,
The vertical joint sealing material 9 is inserted and the joints are filled. To seal the joints, first, the sealing material 9 for vertical joints is inserted into the vertical joints so that its umbrella part 9d protrudes into the horizontal joints, and then the sealing material 8 for horizontal joints is inserted into the horizontal joints. The sealing material 9 may be inserted and inserted at the same time when the individual thin bricks 2 are fixed to the support body 7.

In this way, a sealing material 8 for horizontal joints and a sealing material 9 for vertical joints are inserted into each joint, and these sealing materials are elastic, and the tips of the fins are pressed against each side of the thin bricks 2, 2... This makes it watertight and prevents water from entering inside. The sealing material 9 for vertical joints is inserted into the vertical joints, and the umbrella portion 9d thereof protrudes into the horizontal joints as described above. Therefore, the fins 8b of the horizontal joint sealing material 8 press against the umbrella portions 9d at the vertical joints, as shown in FIGS. 2 and 5. Since the thin bricks 2 are made of fired clay, dimensional accuracy cannot be expected to be very high, and there will be variations in size. Even in such a case, since the vertical joint sealing material 9 is provided with the umbrella portion 9d and is pressed down by the fins 8b of the horizontal joint sealing material 8, watertightness can be maintained reliably.

Although the above embodiment is an attempt to lay tiles without using any joint mortar in the on-site laying method, this embodiment can also be used for the tile formwork pre-attaching method and the tile pre-attaching PC board method.

When used in the tile formwork pre-installation method, the base material is attached to the inner surface of the formwork, tiles are placed on top of the base material, and the sealing material of this example is inserted into the joints.
Concrete can be poured using this formwork.
When the formwork is removed, a tiled wall with joints is automatically created.

When using the tile tipped PC board method, the 6th
As shown in the figure, tiles 11 and 1 are placed on the bed formwork 10.
1,... are arranged at a predetermined interval, and the vertical joint sealing material 9 is fitted so that the umbrella part 9d comes out from the end of the tile 11 to the horizontal joint part, and then the horizontal joint sealing material 8 is fitted. Insert reinforcing bars 12, 12...
Concrete can be poured with the help of Needless to say, each sealant is inserted with its bottom facing upward.

In this way, joint filling can be performed without using mortar in the on-site laying method, and there is no need to perform joint filling later in the tile formwork first-attached method and the tile first-attached PC board method.

Effects of the Invention As described above, according to the present invention, it is possible to fill the joints around each tile without using mortar, and the efficiency of tiling work can be improved. In addition, in the tile formwork construction method and the tile pre-attached PC board construction method, there is no need to perform subsequent joint filling, making it possible to improve the efficiency of wall finishing work.

The sealant for horizontal joints and the sealant for vertical joints are elastic, and the tips of their fins are pressed against the side surfaces of the tiles, so rainwater will not infiltrate through the joints even if they are not covered with mortar.

In addition, an umbrella part was provided at both ends of the vertical joint sealant, and the umbrella part was made to protrude into the horizontal joint, so that the horizontal joint sealant could press the umbrella part.
Watertightness can be maintained even if the dimensions of the tiles vary and do not match.
