Description

TECHNICAL FIELD The present invention relates to a joint sealing method.

(Prior Art) Conventionally, a paste-like amorphous sealing material is used to remove a gap between walls,
The construction method is used to fill the gap between the building frame and the sash.

In particular, since this sealing material is in the form of an amorphous paste, it is solidified after a curing period after filling and sealing is completed.

The sealing material also serves as a cushioning material for waterproofing or for absorbing expansion and contraction of the body.

Silicone or the like is used as the main component of the sealing material.

(Problems to be Solved by the Invention) As described above, the sealing method of filling the paste sealing material in the gap is on-site construction, and requires a curing period until the paste sealing material is solidified.
In particular, when the construction period is limited, sufficient curing cannot be performed, and the sealing function may deteriorate.

Further, dust or the like is likely to adhere to the surface of the sealing material before the sealing material filled in the gaps is dried, and the surface is dirty due to scratches or the like, which is not preferable in appearance.

Further, the sealing is performed on site, and it is necessary to press the sealing material with a spatula or the like after filling the sealing material, so that there is a large difference in finish depending on the skill of the operator. In particular, the sealing material has a paste-like shape and is not good in appearance because it adheres to the edges of the gap to be sealed and has unevenness on the sealing surface.

Then, this invention is made | formed in order to solve the said subject, Comprising: The sealing surface of a joint is beautifully finished, and it aims at providing the sealing method of the joint which can be installed in a short period of time.

(Means for Solving the Problem) In order to solve the above problem, the present invention has the following configuration.

That is, in a method of sealing joints on a wall surface of a building, a primer is applied to the joints, and a paste-shaped irregular sealing material is filled and applied to the surface of the joints or the wall surface that crosses the joints and the irregular shape. Before the sealing material is cured, a material having the same main composition as that of the irregular-shaped sealing material is used, and the fixed-shaped sealing material preliminarily cured and formed into a predetermined shape is applied to the joint portion or the joint portion together with the irregular-shaped sealing material. It is characterized in that the irregular shape sealing material is cured by pressing and joining it to the wall surface portion to integrally fix the irregular shape sealing material and the regular shape sealing material.

Further, it is preferable that the main composition of the irregular sealing material and the regular sealing material is silicone.

(Action) When sealing the joint, after applying the primer to the joint, fill and apply the pace-shaped irregular sealing material on the joint surface or the wall surface near the joint, and apply this irregular sealing material. A fixed sealing material formed in advance in a predetermined shape is pressed against it, and the joint is sealed by hardening the fixed sealing material and integrating the fixed sealing material and the fixed sealing material. Since the fixed shape sealing material is pre-cured and molded according to the width and depth of the joint, the joint can be sealed by simply joining it with the irregular shape sealing material, and the surface of the sealing can be finished cleanly. It becomes easy and requires no skill, and the curing period can be shortened.

(Examples) Hereinafter, preferred examples of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a cross-sectional view showing a state in which a window frame is attached to a window opening portion of a body.

Reinforcing bars 14 are provided so as to project from the inner side surface of the opening 12 formed in the skeleton 10, and support bars 16a protruding from the side surfaces of the window frame 16 are fixed to the reinforcing bars 14 by welding or the like.

There is a joint 18 as a gap formed between the opening 12 and the window frame 14. The joint 18 is filled with a sealing material from the outside O and waterproofed. The joint of this embodiment
The inner side I of 18 may not be sealed.

The present invention is characterized by a method of covering the joint 18 with a sealing material, and the sealing method will be described below step by step.

In this embodiment, a case where construction is performed only from the outside O of the joint 18 will be described.

The inspection of the size of the joint 18 and the type of coating on the inner surface of the joint 18, the base inspection such as missing joints, and the degree of dryness of the base are performed.

Clean and inspect the inside of the joint 18 (adhered surface) for dust, oil, rust, and other mortar.

The above is referred to as pretreatment.

Since the joint 18 has a large depth, a mortar or a foamed resin such as urethane is filled as the backup material 20 to fill up to an appropriate depth. In the case of this embodiment, the backup material 20 is filled up to the inner surface.

The backup material 20 may be filled as needed.

The edge of the opening 12 of the frame 10 forming the joint 18 and the window frame 16
Curing tape 22 is applied to the edge forming the joint 18 of.

The curing tape 22 is for keeping the frame 10 and the window frame 16 from getting dirty.

A primer is applied to the inner surface of the joint (18), and a paste-shaped conventional amorphous sealing material (24) is filled to a predetermined depth of the joint (18).

Subsequently, the shaped sealing material 26 which has already been molded and has a preset width and thickness is pushed into the joint 18. When this fixed-shape sealing material 26 is pushed into the joints 18, the filled paste-like irregular-shape sealing material 24 is filled.
It is integrated with and cured. That is, the paste-like irregular-shaped sealing material 24 also serves as an adhesive for the regular-shaped sealing material 26.

The fixed-shape sealing material 26 is molded in a factory or the like to have predetermined thickness, width, and the like. Further, the material of the fixed-shape sealing material 26 is preferably the same material as the paste-like fixed-shape sealing material 24 containing silicone or the like as a main component.

Further, the regular sealing material 26 may be formed in a rectangular frame shape in advance so that it can be pushed into the gap between the frame 10 and the window frame 16 as it is. Alternatively, it may be formed in a rod shape and cut into a predetermined length and packed as necessary.

That is, since the fixed shape sealing material 26 is molded in advance in a factory or the like, dust and dirt do not adhere to the surface. Also, construction can be done in a short period of time.

Then, the curing tape 22 is peeled off.

In the above procedure, the outside O of the joint 18 is described above.
Although the case where the sealing is performed only from the direction has been described, the sealing may be performed from the inside I as well.

The above-mentioned regular sealing material 26 is formed by pouring a paste-like sealing agent into a mold made of foamed polyethylene or a release agent or the like in accordance with the shape at the site, and taking out after curing. In this case, it can be preformed in a factory or the like, and a curing period on site is almost unnecessary.

FIG. 2 shows another embodiment.

In this embodiment, the joint 28 is narrow.

(1) The pretreatment in the joint 28 is performed in the same manner as above.

(2) At a position slightly apart from the joint 28 with the joint 28 interposed therebetween,
Put the curing tape 32.

(3) Perform primer treatment.

In addition, before the primer treatment, the backup material is applied to the joint 28.
You may fill up to 30.

(4) And a conventional paste-like amorphous sealing material
Apply a thin coat of 24 and stick the standard sealing material 36 on it.

(5) After that, the curing tape 32 is removed.

(6) Then, the inspection is performed.

In this embodiment, since the joint 28 is narrow, the fixed shape sealing material is used.
The 36 is sealed so as to cover the joint 28.

Incidentally, in each of the above-mentioned embodiments, the fixed shape sealing materials 26, 36
Can be manufactured at the factory.
A pattern or the like can be attached to the surface of the.

Although various explanations have been given above with reference to the preferred embodiments of the present invention, it goes without saying that the present invention is not limited to the above-mentioned embodiments, and for example, the shape and size of the regular sealing material are on-site. It goes without saying that many modifications can be made without departing from the spirit of the invention, such as molding according to the above.

(Effects of the Invention) Since the present invention is configured as described above, the following remarkable effects are exhibited.

1) Since the joints are covered with a preformed molded sealing material, there is no need for a curing period on site as in the conventional case, and the construction period can be shortened.

2) Further, since the regular sealing material is formed in a factory or the like and already hardened, dust and dust do not adhere to the surface of the sealing material after sealing the joints. Further, the surface can be constructed in a beautiful state without unevenness.

3) Furthermore, even an unskilled person can easily and neatly perform the construction.
