[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a sealing structure for metal building materials, particularly preferably aluminum (including naturally aluminum alloy) building materials.

[0002]

[Prior Art]

 Aluminum is often used as a building material for sashes and curtain walls.

Aluminum building materials often have extremely complicated cross-sectional shapes in order to reinforce their strength and add various functions. In addition to assembling aluminum building materials in factories, they are often assembled or assembled on-site. Therefore, there is often a demand for sealing after assembly or assembly in the field.

Conventionally, a silicone-based sealant (sealant) has been exclusively used as this type of sealant, but since it is liquid and has two liquids of a main agent and a curing agent, Prior to use, mix and stir, degas in vacuum if necessary, perform pretreatment such as cleaning of applicable seal parts, arrange backup material, apply masking tape, etc., then apply primer if necessary, The process of filling with a caulking gun, troweling the surface of the filled liquid or semi-solid body to even the surface, finally removing the masking tape, and waiting for curing for about 1 week was performed. .. Also, the back-up material needs to be removed at an appropriate time after filling.

[0005]

[Problems to be solved by the device]

 However, with such a conventional method, it is a labor-intensive work, needless to say again. Specifically, for example, as shown in FIGS. 11 to 14, when aluminum building materials 50 having a complicated cross-sectional shape are arranged apart from each other and sealed in the gap, each surface is cut. The backup materials 51, 51 ... Of about 2 to 5 mm are applied, the backup material 52 is also arranged in the gap, and the liquid sealing agent 53 is filled in the area surrounded by them. Further, as shown in FIGS. 9 and 10, when sealing between the small edges of the aluminum building materials 60, 60, the lid plates 61, 61 are fixed to the small edges with screws or the like. Furthermore, when a drain gutter 62 is provided through one lid member 61 and is inserted into the insertion hole 61a of the other lid member 61, the exposed part surface of the drain gutter 62 is set as shown in FIG. , The backup materials 63, 63 ... Are applied and then the liquid sealing material 64 is used for sealing.

As described above, the selection of the dimensions of the backup materials 51, 51 ... Or the backup materials 63, 63. On the other hand, preparing a backup molded product that matches the cross-sectional shape increases the cost and cannot be used at all.

On the other hand, in the case of filling with a liquid sealant, the shape is not sharp, and the surface is uneven, which requires a leveling work, and the small recesses and holes that are not desired to be filled are also filled with the sealant. There is also.

Moreover, it takes about one week to fill the sealing agent and wait for curing, which hinders the progress of other steps. With respect to the backup material for the vertical members of the outer wall, there is a danger in that it is necessary to remove it with a gondola when removing it. Furthermore, a series of operations requires skill, and a simple sealing method has been strongly desired.

Therefore, an object of the present invention is to solve the above-mentioned problems, and to make the sealing particularly easy.

[0010]

[Means for Solving the Problems]

 The above problem can be solved by providing a molded seal material exhibiting rubber elasticity as a seal material in the gap in the seal structure between metal building materials to achieve sealing. In addition, when sealing between metal building materials that are continuously connected with a gap, a plate-like closing material is fixed to the ends of both building materials covering at least the opening to be sealed, and rubber elasticity is shown between these closing materials. The molding sealing material can be fixed to the blocking material by disposing the molding sealing material in the gap and interposing an adhesive between each surface of the molding sealing material and the surface of the blocking material. Further, a plate-shaped molded seal material exhibiting rubber elasticity may be provided so as to straddle the outer surfaces of both building materials, and the both building materials may be fixed to the outer surfaces.

[0011]

[Action]

 In the present invention, a molded seal material is used instead of the conventional liquid seal agent, so that it is not necessary to substantially use a backup material as in the examples described later.

Therefore, the workability is extremely excellent, and no curing is required, so that the work can be performed quickly.

[0013]

【Example】

 The present invention will be described in more detail below. 1 to 4 show a first embodiment of the present invention in relation to the conventional example shown in FIG. 9 and FIG. 10 described above. In the case of sealing the space between the two building materials 1, the ends of both building materials 1, 1 are covered with at least sealing opening portions, and plate-like closing members 2, 2 are fixed by screws 3 or the like, and a rubber member is provided between the closing members 2, 2. An adhesive 10A in which a molding sealing material 10 exhibiting elasticity is arranged in the gap and is applied in advance to the surface of the molding sealing material 10 between both surfaces of the molding sealing material 10 and the closing materials 2 and 2. 10A, the molded sealing material 10 is fixed to the sealing materials 2 and 2.

In this case, as described above, when the drain gutter is provided, the molded seal material 10 can be provided while avoiding the drain gutter. Further, it is not necessary to provide the molding sealing material 10 on the entire surface of the sealing material 2, and it is sufficient to seal only the sealing required portion, for example, only the upper surface portion and the front surface portion as shown in the figure with the molding sealing material 10. As the adhesive, a pressure-sensitive adhesive can be used, and in this case, the building materials 1 and 1 can be pressure-bonded to the molded sealing material 10 for fixation. A liquid adhesive may be separately applied and fixed as the adhesive.

On the other hand, as shown in FIGS. 5 to 8, when the aluminum building materials 20, 20 are arranged with a gap S therebetween and the gap S is sealed, the aluminum building materials 20, 20 are straddled over the outer surfaces of both the building materials 20, 20. Then, a plate-shaped molding sealing material 30 exhibiting rubber elasticity may be provided to fix the building materials 20, 20 to the outer surface. In this case, as shown in FIG. 8, the pressure-sensitive adhesive 30A is applied to the back surface of the molding sealing material 30 in advance, and the building material 20, 20 is fixed while being deformed along the cross-sectional shape of the building material 20. be able to.

In the case where the molded seal material becomes long, if the size corresponding to the length cannot be prepared from the beginning, as shown in FIG. 15, the end portions of the molded seal materials 40, 40 are slanted. It can be cut and abutted with the liquid sealant 41 interposed.

Further, as shown in FIG. 16, the ends of the molded sealing materials 40, 40 can be overlapped. If necessary, an adhesive or liquid sealant of the same quality as the molded sealant 40 can be interposed on the polymerized surface.

Depending on the outer wall structure, the molded sealing material according to the present invention can be used as a base sealing material, and a liquid sealing material can be additionally applied onto this.

The molded sealing material according to the present invention may have a thickness of about 1 to 50 mm. The material is not particularly limited as long as it has rubber elasticity, but silicone-based materials can be preferably used.
