Description

[Detailed description of the invention] (Industrial Icheon field) The present invention relates to an eleventh sealing method.

(Prior art) Conventionally, a paste-like, irregularly shaped sealant was applied to the gaps between walls,
The construction method used is to fill the gap between the building frame and the sash.

In particular, since this sealing material is in the form of an irregular paste 1, the sealing is completed by solidifying after a curing period after filling.

Note that the sealing material also serves as a cushioning material for waterproofing or absorbing expansion and contraction of the building frame.

Silicone is used as the main component of sealants. (Problems to be Solved by the Invention) As described above, the sealing method of filling gaps with a paste sealant is performed on-site, and requires a curing period until the paste sealant solidifies.

Particularly when the construction period is limited, sufficient curing may not be possible and the sealing function may deteriorate.

Further, until the sealant filled in the gap dries, dirt and the like tend to adhere to the surface of the sealant, and the surface becomes dirty due to scratches, which is unfavorable in terms of appearance.

Furthermore, sealing is performed on-site, and requires steps such as pressing with a spatula after filling with sealant, resulting in large differences in the finished product depending on the skill of the worker. In particular, the sealing material is in the form of a paste, and it tends to stick to the edges of the gap to be sealed, and creates unevenness on the sealing surface, resulting in an unsightly appearance.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide a joint sealing method that can cleanly finish the joint sealing surface and can be constructed in a short period of time. shall be.

(Means for Solving the Problems) In order to solve the above problems, the present invention includes the following configuration.

In other words, U such as 17fllVX in the building wall
In sealing to the ground, a primer layer is applied to the joint, and a paste-like amorphous sealing material is further filled, and the main composition is the same as that of the sealing material, and the width and depth of the joint are adjusted in advance. It is characterized by covering the joints with a fixed-shaped sealant that is sized to meet the conditions.

Note that it is preferable that the main composition of the above-mentioned sealant is silicone.

(effect) Next, we will discuss the effect.

A primer layer is applied to the joints, and a paste-like irregular sealing material is then filled, and then a regular sealing material is pasted on the sealing material to cover the joints. Therefore, there is no need for a curing period for the sealing.

(Embodiments) Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Figure 1 is a sectional view showing the state in which the window frame and the window frame are attached to the window opening of the individual. The reinforcing bars 14 are formed on the inner surface of the opening 12 formed in the frame 10.
is provided protrudingly, and a support rod 16a protruding from the side surface of the window frame l6 is fixed to this reinforcing bar l4 by welding or the like.

A joint 18 exists as a gap formed between the opening 12 and the window frame 14. This joint 18 is filled with a sealant from the outside O to perform waterproofing. Note that the inner side work of the joint 18 in this embodiment does not need to be sealed.

The present invention is characterized by a method of covering the joint l8 with a sealant, and the sealing method will be explained step by step below.

In this embodiment, a case will be described in which construction is performed only from the outside O of the joint {8.

■ Inspect the joint 18 dimensions, PR of the painting on the inner surface of joint 18, and inspect the base for missing joints, as well as the degree of dryness of the base. ■ Clean and inspect the inner surface of joint 18 (adhered surface) for dust, bolts, rust, and other mortar.

Note that ■ and ■ above are referred to as preprocessing. ■ Since the depth of joint 18 is large, backup material 20
Fill with mortar or foamed resin such as urethane, etc., and bury it to an appropriate depth. In this example,
The backup material 20 is filled up to the inner surface. Note that this backup material 2o may be filled as necessary.

(2) Apply curing tape 22 to the edge of the opening 12 of the frame 1o that forms the joint 18 and to the edge of the window frame 16 that forms the joint 18.

The curing tape 22 is used to prevent the steel body 10 and the window frame 16 from getting dirty. ■ l] A primer is applied to the inner surface of the base 18, and a paste-like conventional irregular-shaped caulking material 24 is applied. Fill the joint 18 to the specified depth. ■ Next, the already formed sealing material 26 having a preset width and thickness is applied to the joint 18.
Push inside. When this regular sealing material 26 is pushed into the joint 8, it is integrated with the filled paste-like irregular sealing material 24 and hardens. That is, the paste-like irregularly shaped sealing material 24 is different from the shaped sealing material 2.
It also plays the role of adhesive in step 6.

The regular sealing material 26 is formed in a factory or the like to have predetermined dimensions such as thickness and width.

In addition, as for the material of the fixed-shaped sealing material 26, the same material as the paste-like irregular-shaped sealing material 24 containing silicone as a main component is good. Further, the regular sealing material 26 may be shaped in advance into a rectangular frame shape so that it can be inserted into the gap between the frame 10 and the window frame 16 as it is. Alternatively, it may be formed into a rod shape, cut into a predetermined length as necessary, and packed.

That is, since the regular sealing material 26 is pre-shaped in a factory or the like, dirt and dust will not adhere to its surface.

Also, construction can be done in a short period of time.

■ Then, peel off the curing tape 22.

In addition, in the above procedure, the above explanation describes the case where sealing is performed only from the outside O direction of the joint l8,
Sealing may also be performed from the inside I.

The regular shaped sealing material 26 is shaped by pouring a paste-like sealing material into a mold made of foamed polyethylene or a mold release agent according to the shape on site, and taking it out after hardening. In this case, it can be preformed in a factory or the like, and almost no on-site curing period is required.

FIG. 2 shows another embodiment.

This embodiment is an example in which the joint 28 is narrow.

+11 Pre-treatment inside the joint 28 is performed in the same manner as above.

(2) Put the curing tape 32 on both sides of the joint 28 at a position slightly away from the joint 28.

(3) Apply primer treatment. Note that the joints 28 may be filled with a backup material 30 before the primer treatment.

(4) Then, the conventional base 1 is coated with a thin layer of irregularly shaped sealant 24, and then shaped sealant 3 is applied on top of it.
Paste 6. (5) After that, remove the curing tape 32. {6}
After that, we will conduct an inspection. In this embodiment, since the joint 28 is narrow, the regular sealing material 36 is sealed so as to straddle and cover the joint 28.

In addition, in each of the above embodiments, the regular sealing material 26,
36 can be manufactured in a factory, so fixed sealing 2
It is also possible to add a pattern or the like to the surfaces of 6 and 36.

Various preferred embodiments of the present invention have been described above, but it goes without saying that the present invention is not limited to the above-mentioned embodiments. It goes without saying that many modifications can be made without departing from the spirit of the invention, such as molding according to the site. (Effects of the Invention) Since the present invention is constructed as described above, It has the following remarkable effects.

I) Since the joints are covered with a pre-shaped sealant, there is no need for on-site curing period as in the past, and the construction period can be shortened.

2) Furthermore, since the shaped sealant is formed in a factory and has already hardened, there is no possibility of dirt or dust remaining on the surface of the sealant after sealing the joints. Additionally, the surface can be constructed without any unevenness and in a clean state.

3) Furthermore, it can be easily and neatly constructed even by non-skilled workers.
