JP5800350B2 - Finishing agent for building exterior and finishing method for building exterior - Google Patents

Description

  The present invention relates to a technique for improving the aesthetics of the exterior of a building such as a house, and more particularly to a finishing agent and a finishing method applied to a boundary portion between adjacent exterior materials.

  Conventionally, in the exterior (outer wall) of a building such as a house, a plate-shaped (panel-shaped) exterior material is provided side by side. Adjacent exterior materials are joined to form a series of outer wall surfaces that are continuous in appearance. And, in order to maintain airtightness and waterproofness, the gap formed at the joint between adjacent exterior materials is filled with a caulking material (also referred to as a sealing material) or the like. (For example, refer to Patent Document 1).

  Patent Document 1 discloses joint joining (joining joint in the literature) by joining the upper and lower bodies, and describes that the caulking material is placed on the lower surface side. ing. Such joint joining is said to be able to exhibit airtightness and waterproofing functions due to the joining of the upper and lower parts. In addition, like this joint joining, the form of joining “not filled with caulking material after joining” is called a sealingless system. In addition, since the caulking material is hidden by the fruit, it does not appear on the appearance.

  In addition to joint bonding, it has been conventionally performed to join the end portions of the exterior material that are not actually processed, that is, so-called uncut ends, in this case, formed at the end portions of the exterior material. Filling the gaps to be made with caulking material is performed. Thus, the form of joining “filling the caulking material after joining” is called a wet sealing method. Further, since the caulking material is filled after the exterior material is arranged side by side, it appears in the appearance.

  In addition, a caulking material is used that exhibits a silicone-based elasticity in order to adhere to the opposing surfaces with a gap therebetween and to ensure airtightness and waterproofness.

Japanese Patent No. 3557411

  In the above-described sealingless method, when a large gap is generated in the joint portion of the exterior material, the gap appears in the appearance and becomes conspicuous. Factors such as the inclination of the housing side that holds the exterior material are also conceivable, but there are also factors that cause variations in construction by the operator. In some cases, there is a concern that the gap will be very noticeable.

  In addition, if the gap is conspicuous, it will constitute an appearance design in which a continuous series of outer wall surfaces have gaps, and even if functional defects such as airtightness and waterproofness do not occur, There is concern that this may result in defects. Eventually, there is a concern that the owner may be suspected of having poor construction quality.

  On the other hand, in wet sealing, since the caulking material appears in the appearance, there is a concern that the caulking material may be conspicuous even if the gap is hidden. Moreover, since this caulking material is based on silicone, it exhibits a texture similar to so-called rubber. Therefore, it is assumed that the caulking material is greatly different from the texture of the exterior material, and there is a concern that the design of the exterior material may be impaired. In particular, when the outer wall is formed of a ceramic-based exterior material, the texture of the caulking material and the exterior material are different from each other, and there is a concern that the design of the exterior material may be greatly impaired. In addition, it may be possible to reduce the problem by applying the same color system paint as the exterior material on the caulking material, but even if the color can be brought close, it is difficult to eliminate the rubber-like texture. There is also a concern that a new problem may occur that the coating is peeled off and the caulking material is exposed due to aging.

  Further, in view of such a problem in wet sealing, it is clear that the problem regarding the gap is not solved by simply filling the gap with a caulking material in the sealing-less method.

  In view of the above problems, the present invention proposes a novel technique for eliminating a gap formed between adjacent exterior materials and finishing a series of exterior surfaces.

  The problem to be solved by the present invention is as described above. Next, means for solving the problem will be described.

That is, as described in claim 1,
Use a finishing agent for building exterior walls containing at least the following two,
(A) is bonded aggregate (B) the outer package adjacent the paint is juxtaposed a series of outer wall surface continuous in appearance is formed, the waterproof joints of the outer package adjacent the bonding won game Packing In the gap formed between the end portions of the adjacent exterior materials, after securing the exterior materials in parallel with the material, or the waterproofing material arranged on the back side of the front joint flange portion in the joint joining, It is a finishing method of the building exterior that does not fill caulking material to ensure waterproofness ,
For linear gaps that are formed between adjacent exterior materials and appear on the exterior,
Wider than the gap so as to straddle the taper end faces facing each other between adjacent exterior materials,
Applying a finishing agent mixed with aggregate and paint in advance to fill the gaps,
The finishing method for building exteriors.

In addition, as described in claim 2, the paint is the same as the paint used for coating the exterior material, or includes the paint used for painting the exterior material.

Further, as described in claim 3, the finishing agent is discharged from the discharge port of the tube container along a linear gap formed between adjacent exterior materials.

  As effects of the present invention, the following effects can be obtained.

That is, according to the first aspect of the present invention, the texture exhibited by the aggregate and the texture exhibited by the paint are exhibited, and a finish that exhibits a completely different texture from that of a conventional silicone caulking material is possible. Further, the gap appearing in the appearance in the sealingless system can be eliminated by the finishing agent, and the occurrence of problems such as design defects due to the presence of the gap can be prevented.

In the invention according to claim 2, it is possible to bring the texture (color, glossiness, unevenness) of the finish applied to the gap closer to the exterior material. The boundary between the exterior material and the finishing agent can be made more inconspicuous, and a continuous series of outer wall surfaces can be formed in which the joint between adjacent exterior materials is extremely difficult to understand. The “coating material used for coating the exterior material” means that the exterior surface of the exterior material is applied to the exterior surface of the exterior material in addition to the paint applied in advance to the exterior surface of the exterior material when the exterior material is manufactured. A paint used for repairing the paint is also conceivable.

Further, in the invention according to claim 3, the operator can eliminate the gap by squeezing the finishing agent from the tube container and moving it along the gap, and the workability can be improved. it can. In particular, since the gap is locally formed, and it is assumed that it is not necessary to finish all joint portions of the exterior material, it is desirable that the operator can select the finishing portion arbitrarily. . From this point of view, it is preferable to perform the finishing using the tube container.

In the invention according to claim 9,
The operator can eliminate the gap by squeezing the finishing agent from the tube container and moving the finish along the gap, thereby providing a configuration with excellent workability. In particular, since the gap is locally formed, and it is assumed that it is not necessary to finish all joint portions of the exterior material, it is desirable that the operator can select the finishing portion arbitrarily. . From this point of view, it is preferable to perform the finishing using the tube container.

  Next, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 shows that the finishing agent 1 eliminates the gap 11 formed between the adjacent exterior materials 10A and 10B by finishing with the finishing agent 1 according to the present invention. And the appearance of the finishing part to which the finishing agent 1 has been applied is not a texture similar to rubber in the case of using a silicone-based caulking material that has been used in the past, and is similar to the exterior materials 10A and 10B, or the same A texture is exhibited, and the texture exhibited by the exterior materials 10A and 10B is not impaired by the finishing agent 1. Further, since the gap 11 is eliminated, it is possible to solve problems such as design defects and occurrence of doubt about construction quality for the owner without forming an exterior design with a gap on the outer wall surface.

Moreover, let the finishing agent 1 described above be the finishing agent 1 for building outer walls containing at least the following two.
(A) Aggregate (B) Paint

  Thereby, the texture exhibited by the aggregate and the texture exhibited by the paint are exhibited, and a finish that exhibits a completely different texture from that of a conventional silicone caulking material can be achieved.

In addition, the aggregate
It includes at least one of glass beads, resin beads, and spherical silica.

  By using what is listed as an aggregate, it becomes possible to exhibit a texture (color, glossiness, unevenness) close to ceramics-type exterior materials (ceramics siding).

In addition, the aggregate
The average particle diameter is 10 μm or more and 150 μm or less,
Preferably, the thickness is 15 μm or more and 45 μm.

Thereby, it becomes possible to exhibit a texture (color, glossiness, unevenness) close to ceramics-type exterior materials (ceramics siding).
Further, in particular, by using 15 μm or more and 45 μm, it is possible to improve the fluidity of the finishing agent, and when finishing the gap by discharging the finishing agent from the tube container as described later. As a result, good workability can be obtained.
The “average particle size” refers to the volume median particle size (D50) determined by the Coulter method. The average particle size can be measured, for example, by using a measuring device (product name: MULTISIZER) manufactured by Beckman Coulter.

In addition, the aggregate
A spherical shape is preferable.

  Thereby, the fluidity of the finishing agent can be improved, and when finishing the gap by discharging the finishing agent from the tube container as described later, good workability can be obtained. It becomes.

Also, the paint
Water-based paint (mainly using water as a solvent for paint),
Or
Solvent-based paints (those that mainly use organic solvents as paint solvents),
Any one of these or a combination of a plurality of them.

  As described above, the finish is not particularly limited, and a finish suitable for eliminating the gaps in the exterior material can be configured. In particular, when glass beads or resin beads were used as the aggregate, it was confirmed that the glass beads or resin beads were difficult to separate in the solvent-based paint. For this reason, when glass beads or resin beads are used, there is no bias of aggregate (glass beads or resin beads) by using solvent-based paint, and in the finishing agent applied in the gap, It is possible to disperse the material (glass beads or resin beads) evenly, and it can be expected to exhibit a uniform texture.

Also, the paint
It is the same as the paint used for coating exterior materials.
Or
It shall include paint used for painting exterior materials.

  This makes it possible to bring the texture (color, glossiness, unevenness) of the finish applied to the gap closer to the exterior material. The boundary between the exterior material and the finishing agent can be made more inconspicuous, and a continuous series of outer wall surfaces can be formed in which the joint between adjacent exterior materials is extremely difficult to understand. The “coating material used for coating the exterior material” means that the exterior surface of the exterior material is applied to the exterior surface of the exterior material in addition to the paint applied in advance to the exterior surface of the exterior material when the exterior material is manufactured. A paint used for repairing the paint is also conceivable.

<Example>
As shown in Table 1 below, workability and finished feeling were examined using several samples.
In the study, tube work (filled with a semi-solid material and can be squeezed softly) is assumed, assuming that the finishing agent is discharged linearly into the gap between adjacent exterior materials. The finished finish was discharged in a linear form so as to have a length of about 100 cm. In addition, about the tube container, what has a 1 mm aperture discharge port was used in workability | operativity evaluation, and what has a 3 mm aperture discharge port was used for evaluation of a finishing feeling.

  Also, workability, which is one of the evaluation items, is to evaluate the degree of force applied when projecting (fluidity) and the ease of forming a linear shape (followability). “Excellent” indicates that start, continuation, and stop can be adjusted very easily, “Good” indicates that adjustment is easy, and “Yes” indicates that adjustment is possible.

  Also, the finish feeling, one of the evaluation items, is an evaluation of the difference in texture (color, glossiness, unevenness) with the ceramics siding surface. “Good”, and “good” if there is a difference but the texture is not similar to rubber.

From the above results, Sample B is mentioned as a particularly preferred embodiment.
That is,
(A) As an aggregate, at least one of glass beads having an average particle diameter of 40 μm, resin beads, and spherical silica,
(B) As a paint, a paint used for coating an exterior material,
(C) As a blending ratio (weight ratio), (A) :( B) = 1: 1,
The finishing agent is composed of the aggregate (A) and the paint (B).

FIG. 2 shows an example of the form of the joint location to which the finishing agent 1 according to the present invention is applied.
FIG. 2 shows a horizontal cross section at the joint between the exterior materials 10A and 10B adjacent to the left and right, and the exterior material 10A and the exterior material 10B are joined by using the joining accessory 6. This joining accessory 6 is fixed to the housing 4 via the waterproof sheet 5 by a fixing tool (not shown).

  In addition, as shown in FIG. 2, the vertical end surface 12 of the exterior material 10A is configured by a vertical end without step processing such as actual processing by being cut by adjusting the width of the exterior material 10A. On the vertical end surface 13 of the material 10B, a back-to-back flange portion 14 whose back side has been removed by a step process is formed.

  Further, as shown in FIG. 2, the joining accessory 6 is a long member and is disposed long in the vertical direction. The joining accessory 6 is inserted into a portion of the back mating portion 14, and contacts the vertical end surface 12 of the exterior material 10 </ b> A and the back surface 14 a of the back mating portion 14 of the exterior material 10 </ b> B via a packing material 15. It has the structure which has the convex part 62 which contact | connects, By this packing material 15, the airtightness in the gap | interval 11 in the junction part of exterior | packing material 10A * 10B and a waterproofing property are ensured.

  Further, as shown in FIG. 2, the joining accessory 6 has a vertical groove portion 61a in the vertical direction at a position on the back side of the exterior material 10A, and a vertical groove portion 61b in the vertical direction at a position on the back side of the exterior material 10B. The configuration is as follows. Thereby, even if it is a case where water penetrates through the location which should be stopped with the packing material 15, this water can be drained below through the longitudinal groove parts 61a and 61b.

  As described above, in the form shown in FIG. 2, the sealing-less method is realized by using the joining accessory 6 and airtightness and waterproofness are ensured, but the gap 11 is left. If left untouched, problems such as design defects will occur. Therefore, in the form of FIG. 2, it is possible to avoid the occurrence of a problem by performing the finishing using the finishing agent 1.

Moreover, FIG. 3 shows about the other example of the form of the joining location where the finishing agent 1 concerning this invention is applied.
FIG. 3 shows a horizontal cross-section at the joint between the left and right outer packaging materials 10C and 10D. By joining the front mating portion 10c of the outer packaging material 10C and the front mating portion 10d of the outer packaging material 10D, the joining is performed.抉 Joining is to be realized. In addition, an elastic silicone water-stopping material 7 is linearly provided on the front surface 10M of the front fitting portion 10c, and the water-stopping material 7 joins the exterior materials 10C and 10D. The airtightness and waterproofness with respect to the clearance gap 11B formed in a part are ensured.

  As described above, in the form shown in FIG. 3, a sealingless method by joint joining is realized, and airtightness and waterproofness are ensured, but the vertical end surface 10 m of the exterior material 10 </ b> C, If a gap 11B is formed between the vertical end surfaces 10n of the material 10D and the gap 11B remains, problems such as design defects may occur. Therefore, in the embodiment shown in FIG. 3, the occurrence of a problem can be avoided by finishing using the finishing agent 1.

And as can be seen from the embodiment shown in FIGS.
A method of finishing a building exterior in a form in which a sealingless method is applied to a joint between adjacent exterior materials,
For linear gaps that are formed between adjacent exterior materials and appear on the exterior,
By applying the finishing agent in a linear shape, the gap is eliminated.
It is something to do.

  Thereby, the gap appearing in the appearance in the sealingless system can be eliminated by the finishing agent, and the occurrence of problems such as design defects due to the presence of the gap can be prevented.

Further, as shown in FIG. 4, it is conceivable to use a tube container 30 in finishing using the finishing agent 1.
That is, a method for finishing a building exterior,
Along the linear gap formed between adjacent exterior materials,
Causing the finishing agent to be discharged from the discharge port 34 of the tube container 30;
It is something to do.

As a result, the operator can eliminate the gap by squeezing the finishing agent from the tube container 30 and moving the finish along the gap, so that the workability can be improved. In particular, since the gap is locally formed, and it is assumed that it is not necessary to finish all joint portions of the exterior material, it is desirable that the operator can select the finishing portion arbitrarily. . From this point of view, it is preferable to perform finishing using the tube container 30.
The tube container 30 means a container that is filled with a semi-solid material and can be squeezed softly.

  Moreover, as shown in FIG. 4, about the tube container 30, by comprising the discharge tool 31 and the container main body 32 by a separate member, replacement | exchange of the discharge tool 31 and refilling of the finishing agent 1 in the container main body 32 are carried out. The work can be made possible. Further, a cap 35 is detachably provided on the nozzle portion 31a of the discharge tool 31, and has a structure suitable for storage during use.

  In addition, the discharge tool 31 is configured such that a conical through hole 31b is formed in the conical nozzle portion 31a, and the nozzle portion 31a is cut with scissors or the like at predetermined positions 33a, 33b, and 33c. It is possible to form the discharge port 34 having a diameter corresponding to each position. Thereby, the operator can arbitrarily select the diameter of the discharge port 34 at the construction site, and the workability of each worker can be improved.

  Furthermore, as shown in FIG. 5, it is good also as implementing with the tube container 40 of the so-called single use form. In this example, the nozzle member 42 is inserted into the discharge port 41 of the tube container 40.

Moreover, FIG. 6 is for expressing the texture of the finishing agent 1 according to the present invention.
As can be seen from FIG. 6, in the case of the sample B described above, the surface has irregularities and exhibits a matte feeling (matte feeling), so that a ceramic-type exterior material was temporarily used. Even when applied to the exterior gap, the finishing agent 1 does not impair the texture of the ceramics exterior material. In addition, even if there are irregularities, there is no problem because the finishing agent 1 is not intended to ensure airtightness and waterproofness.

  On the other hand, as shown in FIG. 6, when the conventional caulking material 50 is used, the surface does not have unevenness and exhibits a texture similar to that of a semi-liquid rubber surface.

  As can be seen from the above, the finishing agent 1 according to the present invention exhibits a completely different texture from that when the conventional caulking material 50 is used, and the function to be exhibited is also completely different.

  The present invention can be widely applied as means for finishing the gaps between the exterior materials and improving the design of the outer wall.
