DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vertical joint material for blocking a vertical joint gap formed between outer wall panels of an outer wall to prevent rainwater from entering from outside the building.

[0002]

2. Description of the Related Art Conventionally, in order to maintain waterproofness of vertical joint gaps generated between outer wall panels of an outer wall, a sealing material made of a polymer compound is filled and constructed by an on-site wet method.

[0003]

Generally, in an urban area where there are many narrow lands, construction without an external scaffold is required due to a short distance from a neighboring house. It was necessary to build a scaffold for work when filling the sealing material from, and it was not possible to meet such needs. In addition, there is a drawback that the filling operation also requires time, and the construction time is significantly increased accordingly.

An object of the present invention is to provide a dry vertical joint material excellent in workability, durability and design, in place of such a conventional wet sealing material.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, according to the present invention, a longitudinal joint material is provided which closes longitudinal joints formed between outer wall panels adjacent to each other to prevent rainwater or the like from entering from outside the building. A base attached to one of the outer wall panel side surfaces facing each other with the vertical joint gap therebetween, and a pressing portion pressing the other outer wall panel side surface are integrally formed of an elastic material. The inside and outside of the base building protrude in the joint width direction in a thick state, and the pressing portion is formed so as to be curved so as to connect the protruding tips of the base portion. A plurality of protrusions are formed.

[0006] With this arrangement, the pressing portion is arranged so that the adjacent outer wall panel is applied from the side while adjusting the joint to the vertical joint material previously attached to the side surface of the outer wall panel. It can be pressed against the side of the panel to maintain watertightness.

The pressing portion can be deformed into a substantially W shape whose central portion is recessed in the joint width direction when pressing the side surface of the other outer wall panel.
It is possible to press with high supporting pressure by the two convex portions.
When the joint width becomes wide due to a dimensional error or mounting error of the outer wall panel, the pressing portion becomes substantially straight without the dent, and the tip of the plurality of protrusions supports the other outer wall panel side surface with a high support. Press with pressure.

Further, a reinforcing material such as a galvanized steel plate for suppressing the deformation is buried in the base in the longitudinal direction. Furthermore, the base is adhered to the side surface of the one outer wall panel via an acrylic adhesive that is unlikely to cause heat dripping. Furthermore, a fin piece is formed in the base portion in a longitudinal direction to close a gap between the one outer wall panel side surface generated in the attached state.

The elastic material constituting the base portion and the pressing portion is a polyolefin-based thermoplastic elastomer which is a non-migratory material having excellent long-term heat resistance, weather resistance and chemical resistance.

Non-migratory material with excellent long-term heat resistance, weather resistance, and chemical resistance that does not contain plasticizers, has high resilience, and contains no chlorine. Is
Stable performance can be maintained over a long period of time, and environmental pollution is low and recycling is possible.

A pair of thick portions 13 and 13 having a substantially triangular cross section are formed on the base 10 by projecting the inside and outside of the building in the joint width direction. Also, the base (1
On the vertical mounting surface (14) of (0), an adhesive material (15) made of an acrylic double-sided adhesive tape is stuck along the longitudinal direction, and a pair of fin pieces are sandwiched between the adhesive materials (15). (16)
(16) extends from the vertical mounting surface (14).

By using the acrylic adhesive (15) as described above, it is possible to prevent a problem that heat drooling hardly occurs and the outer surface of the base material (2) is stained black by heat dripping. In addition, the fin pieces (16) and (16) can close the gap between the base (10) and the side surface of the base material (2) generated when the longitudinal joint material (5) is attached, so that rainwater can enter through the gap. In addition, it is possible to prevent a problem that the adhesive (15) is deteriorated by ultraviolet rays entering through the gap.

Further, a reinforcing member (18) made of a galvanized steel plate for suppressing deformation is embedded in the base (10) in the vertical direction, thereby maintaining the straightness of the vertical joint material (5). And elongation of the longitudinal joint material (5) at the time of sticking to the substrate (2) can be prevented.

The pressing portion (11) is a thick portion (13) (1) of the base (10).
3) is formed so as to be curved so as to connect the front ends thereof, and three protrusions (20), (20), (20) extending in the vertical direction are formed on the outer surface thereof in parallel with each other.

Next, the joint construction using the vertical joint material (5) will be described. First, the base material of the outer wall panel (1)
(2) A vertical joint material (5) is attached to the side surface via an adhesive (15), and a waterproof material (6) is also attached to the side surface of the frame (3). Then, as shown in FIG.
(1) is carried into the site and built one by one. At this time, as shown in FIG. 4, the vertical joint material (5) and the waterproof material (6) of the outer wall panel (1) already built are used. Then, the outer wall panel (1) adjacent to the outer wall panel (1) is arranged so as to be applied from the side while adjusting the joint.

In this arrangement state, as shown in FIG. 5, the base material (2) of the adjacent outer wall panel (1) is pressed by the pressing portion (1) of the vertical joint material (5).

In addition, the waterproof material (6) is also used for the frame (3) of the adjacent outer wall panel (1)
To compress and thereby ensure watertightness in two stages. further,
The pressing portion (11) deforms almost without protruding in and out of the building, and the base (10) hardly deforms due to the thick portions (13) (13) protruding in the joint width direction,
Since the outer surface of the base (10) does not bend or dent, the appearance of the outer wall can be favorably maintained.

In the case where the joint width is widened due to a dimensional error or a mounting error of the outer wall panel (1), as shown in FIG. 6, the pressing portion (11) has no dent and has a substantially linear shape. In other words, the tips of the three projections (20), (20), (20) press the side surface of the adjacent base material (2) with a high supporting pressure to ensure watertightness. In this case, also in this case, the base portion (10) is hardly deformed, and the appearance of the outer wall can be maintained well.

After arranging the outer wall panels (1) (1)... At predetermined positions in this way, these outer wall panels (1)

Filling (7) completes the joint construction.

As shown in FIG. 7, the outer wall panel (1)
If a window frame (30) is provided in the window frame (30)
If the vertical joint material (5) is attached to the side surface of the window frame (30), the vertical joint space between the side surface of the window frame (30) and the base material (2) side surface of the outer wall panel (1) opposed thereto can be closed.

[0021]

As described above, according to the present invention, the watertightness in the vertical joint gap is obtained by merely applying the adjacent outer wall panel from the side to the vertical joint material previously attached to the side surface of the outer wall panel. The joint work can be performed while holding the joint, so that there is no need to construct a scaffold for work as in the conventional joint work, and it is possible to respond to the demand for construction without scaffolding on narrow land and to reduce the construction time. Can also be significantly reduced.

Further, since the base protrudes in the joint width direction in a thickened state, the deformation amount is small, so that the outer surface of the base does not bend or dent due to the joint construction, and the design of the outer wall is improved. Can be achieved. further,
Since the pressing portion is curved so as to connect the thick portion, the repulsive force of the pressing portion can be increased, and since a plurality of projections for increasing the supporting force are formed on the pressing portion, High water stoppage can be realized.

Further, since the pressing portion can be deformed into a substantially W shape in which the center portion is recessed in the joint width direction,
When the other outer wall panel side surface is pressed, the outer wall panel deforms almost without protruding in and out of the building, whereby the design of the outer wall can be further enhanced.

Further, since the reinforcing material is embedded in the base, the straight joint can be kept straight, and the longitudinal joint can be prevented from being stretched at the time of sticking to the base material.
Workability can be improved.

Further, by adhering the base with an acrylic adhesive, it is possible to prevent a problem that heat dripping is unlikely to occur and that the outer wall is stained black by heat dripping. In addition, by forming fins on the base, it is possible to close the gap between the base and the side of the outer wall panel that occurs when the vertical joint material is bonded to the side of the outer wall panel via an adhesive, and rainwater enters through the gap. Or the adhesive material may be deteriorated by ultraviolet rays entering through the gap.

By using a polyolefin-based thermoplastic elastomer as the elastic material constituting the base and the pressing portion, it is possible to maintain a long-term stable performance and to realize a recyclable vertical joint material with little environmental pollution. Can be.
