DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technology related to a wall of a building having joints, and more particularly, to a wall member of a building juxtaposed with a joint therebetween, and a joint seal of a wall of the building using the wall member. The present invention relates to a structure and a joint sealing method.

[0002]

2. Description of the Related Art Conventionally, panel materials such as siding, ALC, glass, tiles, PC boards and the like, blocks, bricks, reinforced concrete, etc., which have been integrated with each other, have been used for the outer walls of buildings and the inner walls of buildings. I have. Here, when a panel material such as siding, ALC, glass, tile, or PC board is used as a wall member, joints are generated between adjacent wall members, and blocks, bricks, When reinforced concrete or the like is used as the wall member, joints occur at the joints. In all of these joints, sealing is performed for the purpose of waterproofing or the like.

[0003] As one type of joint sealing structure for a wall portion of such a building, there is known a joint sealing structure using an irregular-shaped sealing material as described in JP-A-8-93085. ing. Such a joint seal structure can provide higher waterproofness by bonding an irregular-shaped sealing material, as compared with a joint sealing structure using a fixed-shaped sealing material described in JP-A-11-256735 and the like. It is widely used because it is possible to easily cope with variations in joint dimensions and part shapes, and to ensure waterproofness.

[0004] By the way, such a method of performing joint sealing using an irregular sealing material is generally performed by injecting and filling an irregular sealing material into the joint after applying a primer to an edge portion of a wall member. At this time, in order to prevent contamination of the wall surface due to protrusion of the irregular-shaped sealing material from the joint, and to align the edges of the irregular-shaped sealing material neatly without meandering, the walls arranged on both sides of the joint. After attaching a masking tape to the edge of the member, an irregular sealing material is injected into the joint.

[0005] However, if the masking tape is not in close contact with the surface of the wall member, the irregular sealing material will penetrate into the gaps and stains will occur on the wall surface. Further, when the masking tape is peeled off at the time of injecting the irregular sealing material, there is a problem that the irregular sealing material protrudes, resulting in a very poor finish. Especially in recent years,
For the purpose of improving the design effect, for example, sanding type or tile tone adopted for siding boards, tile-cut type, etc., or lysine and skin adopted for concrete, irregularly shaped surfaces such as stucco, The operation of sticking the masking tape along the surface in a close contact state is extremely troublesome and difficult, so there is a problem that it takes a long working time and the finish is deteriorated. Further, it is difficult to secure a sufficient adhesive force and an adhesive area of the masking tape, and even if the tape is applied with a long time, there is a possibility that the masking tape may be peeled off at the time of sealing and a defect may occur.

[0006]

The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to easily and quickly apply a masking tape to a wall member having an irregular surface. To provide a novel construction wall member, joint seal structure, joint seal construction method, etc., which can be adhered in a close contact state and can obtain excellent aesthetics after construction of an amorphous sealing material. The purpose is to:

[0007]

An embodiment of the present invention which has been made to solve such a problem will be described below. The components employed in each of the embodiments described below can be employed in any combination as possible. In addition, aspects or technical features of the present invention are not limited to those described below, but are described in the entire specification and drawings, or based on the invention ideas that can be understood by those skilled in the art from the descriptions. It should be understood that it is recognized on the basis of.

First, a feature of the present invention relating to a building wall member is a building wall member which is arranged side by side with a joint therebetween to constitute a building wall, and has a surface having unevenness or roughness. With a non-flat irregular surface such as a surface, a flat sticking surface extending continuously over the entire length of the joint on the surface of the joint side end portion is formed with a width of at least 1.0 mm or more. Features.

In such a wall member having the structure according to the present invention, since the surface to which the masking tape is applied is flat, it is extremely difficult to apply the masking tape along the surface in close contact. It is simpler and requires less work time, and is also excellent in finished design. Furthermore, since the width dimension of the sticking surface is 1.0 mm or more, it is possible to easily secure a sufficient adhesive force and an adhesive area of the masking tape, and peeling during sealing is prevented as much as possible. obtain. In addition, as the width dimension of the sticking surface,
Preferably 2.0 mm or more, more preferably 3.0 mm
It is above. In addition, the upper limit of the width dimension of the sticking surface is not particularly limited, and can be appropriately set in consideration of the sticking width of the tape and the like.
It is set to 30.0 mm or less, more preferably 20.0 mm or less, and still more preferably 5.0 mm or less.

[0010] In the wall member having the structure according to the present invention, for example, the sticking surface is a flat surface that spreads at substantially the same constant height as the portion most protruding to the front side except for the sticking surface. Is preferably adopted. Alternatively, a configuration in which the surface side corner of the joint side end is inclined in a corner-cut shape, and the sticking surface is formed by such an inclined surface, and the joint gradually expands toward the surface side, It is suitably employed in the present invention. By employing such a configuration, workability at the time of attaching the masking tape is improved. In addition, the latter wall member in which the sticking surface is formed by the inclined surface may be formed by cutting the conventional wall member and then corner-cutting the surface side corner of the joint side end, or the surface of the joint side end in advance. The wall member may be formed with a molding die whose side corners are inclined in a corner cut shape.

Further, in the present invention, a masking tape is stuck on the sticking surface of each of the building wall members positioned so as to sandwich the joint according to the present invention as described above. Thereafter, a joint sealing method for filling a gap between the joints by filling the joint with an irregular-shaped sealing material is also characterized. According to the joint sealing method of the present embodiment, the operation of sticking the masking tape in close contact along the sticking surface is extremely simple, so that the work time is short. In addition, since the irregular sealing material is prevented from entering between the sticking surface and the masking tape, the design at the time of finishing is excellent.

Further, the present invention relates to a building wall member having uneven irregular surfaces such as irregularities and rough surfaces which constitutes a wall of a building by being juxtaposed with an joint therebetween.

An adhesive jig for joint seal construction having a stop part integrally is also characterized.

In the sticking jig having such a structure according to the present invention, even if the wall member does not have a flat sticking surface on the surface of the joint side end, the adhesiveness of the masking tape can be maintained. improves. In addition, since the locking portion enters the joint with a length that does not reach the back end of the wall member,
Since the irregular sealing material is directly adhered to the wall member, the waterproofness of the joint can be highly secured. It is desirable that the locking portion is formed continuously in the longitudinal direction of the jig, but may be discontinuous. In addition, the width dimension of the sticking plate portion is preferably 2.0 to 5.0 mm, more preferably 3.0 to 5.0 mm. Further, as a material of the sticking jig, a hard material such as a synthetic resin or a metal is desirable, and may be the same material as the wall member.

In addition, the present invention provides a plurality of architectural wall members having irregularly shaped irregular surfaces such as irregularities and rough surfaces, which are arranged side by side with joints therebetween and each of the architectural members positioned with the joints therebetween. The bonding jigs having the structure according to the present invention as described above are mounted on the surface side corners of the joint side edge of the wall member, and the irregular sealing is performed on the joint. The joint sealing structure is filled with a material, and the irregular-shaped sealing material is bonded to the locking portions of the bonding jigs on both sides and the side surfaces of the building wall member on both sides, respectively. And

In the joint sealing structure according to the present invention, a masking tape can be securely adhered to the joint side end of the wall member by employing a specific attaching jig. This makes it possible to prevent contamination due to the attachment of the irregular sealing material to the surface of the wall member, and to easily obtain excellent design properties. In addition, since the locking portion of the attaching jig enters the joint with a length that does not reach the back side end of the wall member, the irregular-shaped sealing material injected into the joint is attached to the joint side end of the wall member. It is directly bonded to ensure the joints are waterproof.

Further, the present invention provides a plurality of architectural wall members having irregularly shaped irregular surfaces such as irregularities and rough surfaces, in which a plurality of architectural wall members are juxtaposed with the joints therebetween, and each of the architectural members is positioned with the joints therebetween. The attachment jigs having the structure according to the present invention as described above are attached to the surface side corners of the joint side edge of the wall member for use, and the attachment in the attachment jig is performed. The present invention is also characterized in a joint sealing method for filling a gap between the joints by applying a masking tape to the surface of the plate portion and then filling the joint with an irregular sealing material.

According to such a joint sealing method,
Since the surface of the sticking plate portion is flat, the work of sticking the masking tape along the surface of the sticking plate portion in a close contact state is extremely simple, and the working time is reduced. In addition, since the irregular-shaped sealing material does not enter between the surface of the sticking plate portion and the masking tape, the design at the time of finishing is excellent.

In a preferred embodiment of the joint sealing method according to the present invention, the masking is applied to the surface of the sticking plate portion of the sticking jig before the sticking jig is attached to the building wall member. It is also possible to attach a tape, thereby further improving the efficiency of the construction work.
