DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint filling building material useful for construction of a construction plate, and a joint treatment method using the same.

[0002]

2. Description of the Related Art Construction plate materials such as gypsum board and calcium silicate plate have excellent properties such as fire resistance and dimensional stability, and are widely used as interior base materials and finishing materials for buildings. I have.

[0003] Commercially available construction plate materials are classified into square edge boards, tapered edge boards, bevel edge boards, and the like according to the shape of the edge portions. In addition, as a construction method of the construction plate material, using these, a wall, a pillar, a frame of a beam, etc., affixed in a state where the side of the construction plate material is aligned, further to improve the airtightness, heat insulation, etc., taper or 2. Description of the Related Art A construction method of jointly treating a bevel portion with a putty or the like is widely performed.

[0004] An example of a method for performing the joint processing will be described with reference to FIGS. First, as shown in FIG. 1, a construction plate 1 having a bevel edge is made adjacent to a state where the side surfaces 2 are aligned. Next, a mesh-shaped fiber tape 3 is attached so as to cover the joint groove portion 10 formed at the edge of the construction plate 1. Next, from above the fiber tape 3
The joint putty 4 is pressed with a spatula or the like and applied while passing through the mesh of the fiber tape 3 to completely fill the joint groove 10, and then left to cure the joint putty 4.

[0005] Even if the joint putty 4 completely fills the joint groove 10 immediately after the application, the joint putty 4 becomes thin after curing as shown in FIG. 2 and the joint is depressed. In order to further fill the depressions, an intermediate coating putty 5 is applied to fill the joint grooves 10 and harden. Further, when the intermediate coating putty 5 is thinned and the joint is depressed, an intermediate coating putty (not shown) is further applied as necessary, and finally, a finishing putty 6 is applied to obtain a flat treated joint. .

[0006] When the construction method is used, the length of the construction period, poor handling of the putty, and the like pose problems. That is, in order to correct the above-mentioned thinness, the joint groove must be filled a plurality of times to correct it. Further, after the putty is applied, it must be left for a certain period of time in order to cure, so in order to fill the joint groove a plurality of times,
It is necessary to leave for a certain period each time one filling is performed,
Extend the construction period. Also, when applying putty at the construction site,
There is a risk that the construction site will be soiled due to the application of the putty by the application of a spatter or a spatula, and care must be taken so as not to stain the construction site each time the above-described multiple application steps are performed.

[0007] In order to solve these problems, a powder paste for joints having a relatively small thickness, a paste joint for paste which does not need to be ground in place, a joint putty having a short curing time or a curing accelerator mixed in joint putties, Various methods and methods using them have been proposed, but none of them have solved all the above-mentioned problems.

[0008]

SUMMARY OF THE INVENTION An object of the present invention is to provide a building material for filling joints which can be constructed without considering thinness and has good handleability.

Another object of the present invention is to provide a joint treatment method that can be easily and simply performed in a short period of time.

A joint treatment method is provided.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION The joint filling building material for construction boards of the present invention is a construction material for filling joint grooves of joints formed at edges between construction boards when a plurality of construction boards are adjacent to each other. And has a cross-sectional shape substantially matching the joint groove.

The construction board is not particularly limited, but is mainly used for interiors such as gypsum board, calcium silicate board, asbestos cement perlite board, asbestos cement calcium silicate board, other artificial wood, and flame retardant plywood. Various construction plate materials that are used as a building material and are generally subjected to a method of performing a joint treatment by filling a joint groove generated by a bevel edge or a tapered edge can be given.

The term "groove joint" means a groove formed at an edge portion between each plate material when a plurality of plate materials for construction are made adjacent to each other. Usually, a plurality of plate materials for construction having a shape such as a tapered edge or a bevel edge are made adjacent to each other. It is a groove having a V-shaped cross section that is generated when it is pressed. Further, the cross-sectional shape substantially matching the joint groove means that the cross-sectional shape is the same as the cross-section of the joint groove, but a dimension larger than the joint groove as long as the effect of the present invention is not impaired. Or it may be a small size. For example, in the case of commercially available bevel edge construction plates made of gypsum, calcium silicate, or the like, many of them are joint grooves having an isosceles triangular cross section with a width of 6 mm and a depth of 3 mm on the surface side when laminated. Is formed, so that the joint-filled building material of the present invention, when used for a bevel edge construction plate of this shape, has substantially the same cross-sectional dimensions as an isosceles triangle having a base of 6 mm and a height of 3 mm. However, it is possible to make the joint filling building material of the present invention using a plastic and / or elastic substance. When the joint groove is filled with pressure and used, the size may be larger. Specifically, for example, when used for a construction plate having a joint groove having a width of 6 mm and a depth of 3 mm formed on the above-described surface side, the bottom side is 5 to 7 mm, and the height is 2 to 4 mm. Is preferred.

Further, in the case of a commercially available construction plate material having a tapered edge such as a tapered edge gypsum board, most of them have a width of 12 mm on the surface side when they are laminated.
Since the joint filling building material of the present invention has a taper in which a joint groove having an isosceles triangular cross section of 0 mm and a depth of 1.25 mm is formed, the joint filling building material of the present invention has a Bottom 120mm, Height 1.25m
m can be approximately the same cross-sectional dimension as an isosceles triangle, but it can be smaller than this in order to apply an adhesive, a finishing putty, etc., described later. In the case where the joint groove is formed by using a material having elasticity and being pressed to fill the joint groove, the size may be larger. Specifically, for example, in the case of using the above-mentioned construction plate material in which a joint groove having a width of 120 mm and a depth of 1.25 mm is formed on the surface side, the bottom side is 1
It is preferable that the height is 10 to 130 mm and the height is 1.0 to 1.5 mm.

The joint filling building material of the present invention has a shape that is continuous in the vertical direction of the cross section. The length in the vertical direction is not particularly limited, and can be various lengths with good handling. For example, JIS A 6901 (198
The length of the gypsum board according to 3) is 1820 mm, 2
The joint filling building material of the present invention fills joint grooves formed on the side surfaces in the length direction of these gypsum boards since those having a length of either 420 mm or 2730 mm and a length of 3030 mm are widely commercially available. If used to make the same, they can be the same length. Also,
It may be used after being cut into a longer dimension, or may be used after being cut into a shorter dimension.

The joint-filled building material of the present invention has the above-mentioned shape, and is adapted to fix the preformed joint-filled building material in the joint groove when performing the joint processing of the construction plate. .

Although the material of the joint filling building material of the present invention is not particularly limited, it can be deformed according to the warpage of the construction plate material, inconsistency such as a step of the combined construction plate material, unevenness in the joint groove, and the like. A material that has a certain degree of plasticity and / or elasticity, has good compatibility with putty, and is easily processed by cutting or the like is preferable. Specific examples include rubber, felt such as hard felt, wood, styrofoam, plastic, paper, a fibrous integrated material obtained by accumulating ceramic fibers, or a composite material thereof. Aggregates are preferred.

In the joint treatment method of the present invention, the step of fixing the joint-filled building material in the joint groove in the treatment of the joint generated at the edge between each of the construction plate materials when a plurality of construction plate materials are made adjacent to each other. Including. At the time of the fixing, it can be fixed by bonding using an inorganic adhesive such as a water glass type or an organic adhesive such as an emulsion type or a non-solvent type. Further, after the step of fixing the joint filling building material, a fiber tape or the like used for ordinary joint treatment can be attached thereon. Then, by further applying a finishing putty thereon, the joint processing can be completed.

[0020]

According to the present invention, the joint filling building material for construction plate material is
Since this is a joint-filled building material having a cross-sectional shape substantially matching a joint groove generated when a plurality of construction plates are adjacent to each other, the joint-filled building material formed in advance is adapted to be fixed in the joint groove. Compared with the conventional putty for joints, it can be constructed without considering thinness, and can be used as a building material having good handleability.

In the joint treatment method of the present invention, since the joint filling building material is used, filling of the joint groove is simpler than the joint treatment method using a conventional joint putty.
There is no need to fill the joint groove a plurality of times to reduce the thickness of the joint, and the joint can be simply and quickly constructed.

[0022]

The present invention will be described in more detail with reference to the following examples.
The present invention is not limited to these.

With reference to FIG. 3, an example of a construction method by the joint treatment method of the present invention using the joint filling building material of the present invention will be described. First, a construction plate 1 having a bevel edge
Are adjacent to each other so that the side surfaces 2 are aligned. Construction board 1
Between them, joint grooves 30 each having an isosceles triangular cross section are formed. Next, an adhesive 31 such as an inorganic adhesive such as a water glass type or an organic adhesive such as an emulsion type or a non-solvent type is applied to the joint groove 30, and then the plasticity and / or
Alternatively, a prism-shaped joint filling building material 32 made of an elastic material and having an isosceles triangular cross section is attached. At this time, if the joint filling building material 32 protrudes from the level of the surface 33 of the construction plate 1, the joint filling building material 3
2 can be cut or pressed to condition the surface.
Next, a mesh-shaped fiber tape 3 is attached so as to cover the joint groove. As the fiber tape 3, the same material as that used in the conventional joint processing method using joint putty can be used. Next, after the finish putty 34 is applied from above the fiber tape 3, the finish putty 34 is hardened by leaving it, and a flat joint is obtained. According to this construction method, compared to the conventional joint treatment method, a plurality of joint groove filling steps with joint putty and a leaving step for curing joint joint putty after each joint groove filling are required. Therefore, joint processing can be performed quickly. Also, the process of using putty is
Since it is only one time to apply the finish putty, there are few processes that must be considered so as not to stain the construction site,
It can be easily constructed.
