Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint construction method. More specifically, the joint main body is leaned against a floor surface, and concrete is placed without fixing with support legs or mortar incorporated in the joint material main body. The present invention relates to a joint construction method for forming joints.

[0002]

BACKGROUND OF THE INVENTION Conventionally, as shown in, for example, Japanese Utility Model Publication No. 53-51611, a joint material main body is formed of a foam material, and a head portion thereof is covered with a reinforcing cap. A so-called expandable joint material is widely used in which the base is erected on the base surface by using the built-in support legs, and the periphery of the leg member is fixed with mortar.

For the joint construction of the above method, the fixing work with mortar is complicated, the thickness of the holding concrete becomes thin at the portion where the mortar is present, cracks easily occur, and so-called bottom joints cannot be cut. Problems such as these have been pointed out.

Therefore, as an alternative joint construction method, the present applicant leans the joint material main body in the shape of a grid on the surface of the base in every fixed section, and the side surface side of the joint material main body (outside of the base material).
Place the fixing member on the base, place the concrete with the pressure to prevent the joint material main body from shifting or bending due to the pressure when placing the concrete, remove the fixing member after curing the concrete, and then An improved joint construction method of reusing for joint construction was proposed by Japanese Patent Publication No. 53909/1993.

The joint material fixing member disclosed in this publication is formed of a heavy material such as metal, and various fixing members for preventing the joint material main body from curving are used. In need of. However, when it is applied to actual joint construction, there remain problems in terms of storage and transportation of the fixing member and usability. Therefore, the present applicant further advanced the research, and previously proposed a method in which the fixing member for the joint material is formed of a hollow container and a heavy object such as water or sand is enclosed and used in the container. Experiments have revealed that further improvement is needed.

[0006] One of them relates to an adhesive placed on the lower surface of the joint material body. When the joint material main body is leaned against the floor surface, it is necessary to hold the lower surface of the joint material main body with an adhesive in order to overcome the pressure at the time of placing concrete, though the fixing member is used for reinforcement. Therefore, in the case of conventional joint materials, the maker manufactures by attaching an adhesive to the lower surface of the joint material body and covering the upper surface with release paper, and at the site it can be used by removing the release paper and leaning it against the floor. Was said.

However, since the work of sticking the adhesive on the lower surface of the joint material body cannot be automated and is all manual work, the manufacturing cost rises remarkably in combination with the rise in labor cost, and there is a situation in which it is difficult to adopt. There is. Also, with joint materials of such specifications, they are packed on top of each other at the time of shipping, so the adhesive swelled from the side where there is no release paper sticks the joint materials together and forces them to separate. Then, it is pointed out that the adhesive is peeled off and the usability is poor.

As is apparent from the above, the present invention aims at clarifying an improved joint construction method capable of performing joint construction with good workability and at low cost.

[0009]

A joint construction method according to the present invention draws a joint arrangement line on a base surface, arranges an adhesive or an adhesive according to the joint arrangement line, and then, puts the adhesive or the adhesive on the adhesive. Arrange the joint materials and fix them to the base surface, and then perform the concrete pouring while supporting the side surface of the joint material with the fixing member. Fixing with a weight that can not withstand the pressure during concrete pouring. Members are arranged at regular intervals from the side surface of the joint material main body arranged on the base surface, and the side surface of the joint material is supported by the connecting member arranged between the fixing member and the joint material. It is characterized by doing while doing.

DETAILED DESCRIPTION OF THE INVENTION Next, a joint construction method according to the present invention will be described with reference to the accompanying drawings.

FIG. 1A shows a state in which a joint arrangement line 10 is drawn on a base surface on which a joint material is arranged. The joint placement line may be a single line as shown in FIG.
(B) As shown in the figure, in addition to the arrangement reference line 11, it is preferable to draw auxiliary lines 12 and 12 indicating the width of the lower end of the joint material main body. This is because the width of the lower end of the joint material main body differs depending on the joint material maker and the product number. Therefore, by drawing the auxiliary line 11, it is possible to prevent excess or deficiency of the arrangement of the adhesive, which will be described later.

Next, as shown in FIG. 2, the joint material arrangement line 1
The adhesive 20 is arranged according to 0. The adhesive 20 has a width corresponding to the width of the lower end of the joint material main body, and is wound in a roll shape 21, similarly narrow width 22,
Various forms such as those 23 cut into the length of the joint material, those cut into strips of an appropriate length, those cut into the length corresponding to the width of the lower end of the joint material 24, etc. Provided. Therefore, the adhesive 20 can be arranged in various forms such as a form in which it is arranged over the entire width of the lower end of the joint material body, a form in which it is arranged in several lines, and a form in which it is arranged in the width direction at a predetermined interval.

The arrangement of the adhesive 20 is as described in Japanese Patent Publication No.
It may be carried out for each block in the construction method disclosed in Japanese Patent No. 53909/1993, divided into several blocks, or carried out for all blocks.

As shown in FIG. 3, when the placement of the adhesive material 10 is completed, the joint material main body 30 is arranged on the adhesive material 10 and pressed to enhance the adhesive effect, and then the fixing member 40 is placed. Then, the side surface side of the joint material is reinforced and supported.

When the above preparatory work is completed, concrete is placed in each block, and then the above-mentioned Japanese Patent Publication No.
As shown in Japanese Patent No. 53909, the fixing member 40 is moved or removed to another block, and the joint construction is completed by repeating this procedure.

In the embodiment described above, butyl rubber is preferable as the pressure-sensitive adhesive 20 that can be used, but the present invention is not limited thereto, and the term "pressure-sensitive adhesive 20" includes various industrial adhesives. . Therefore, as shown in FIG. 4, a sticker or adhesive that is a viscous liquid is applied according to the joint material disposition line using an applicator such as that used for applying a sealing agent, and the lower end of the joint material main body is fixed. It may be a mode that does. Further, the pressure-sensitive adhesive or the adhesive may be pressure-sensitive, heat-sensitive, or other two-liquid reaction type.

Here, the joint material 30 and the fixing member 40 used will be briefly described.

The joint material 30 is composed of a joint material main body 31 formed of a synthetic resin foam and a reinforcing cap 32 capped on the joint material main body 31, and the joint material main body 31 is provided as necessary.
The lower end side of the is formed in a rectangular or trapezoidal shape so that the stability when standing and the connection with the base surface are strong. Unlike the conventional joint material, the joint material shown in the drawing does not have a supporting leg.

As the fixing member 40 for supporting the side surface of the joint material, a member formed of a heavy material such as metal as disclosed in Japanese Patent Publication No. 53909/1993 or a hollow member as shown in FIG. It is possible to use a structure in which water, mortar, concrete, sand, etc. are poured into the structure and used as a heavy object.

The height of the joint material (height from the base surface to the upper surface of the cap 32) regulates the thickness of the concrete to be poured, and therefore, the prepared joint materials have various heights. There is something. Therefore, when the height of the fixing member 40 is lower than the height of the joint material, even if the fixing member 40 is arranged close to the joint material 30, the surface of the placed concrete is Even when the upper surface of the cap 32 is rubbed with the plaster ruler during the smoothing operation, the fixing member 40 does not get in the way. However, when the height of the fixing member 40 exceeds the height of the joint material, the fixing member 40 becomes an obstacle, so the concrete leveling work becomes extremely complicated, and in the case of a rough worker. There is a risk that the fixing member 40 may be fallen down.

Therefore, in the joint construction method of the present invention, as shown in FIG. 3, the fixing members 40 are arranged at a fixed distance from the arrangement position of the joint material 30, for example, about 5 cm to 10 cm, and between them. It is preferable that the side surface of the joint material 30 is supported by interposing the connecting member 41. As the connecting member 41, one or several plate materials formed of the same synthetic resin foam material as that used to form the joint material body 10 can be used in a stacked manner, or
It is also possible to configure a dedicated connecting member with a metal plate or a rod.

[0022]

According to the joint construction method of the present invention, a pressure-sensitive adhesive cut into a predetermined size is arranged on the base surface to be joint-constructed, or is applied with a viscous liquid adhesive. The bottom surface of the joint material can be firmly fixed to the base surface with, and at the same time, by using the fixing member that supports the side surface, it is possible to place concrete, so stick the adhesive It is much cheaper than the conventional joint material that is sold on the market and has good workability, so it has the advantage of being effective in reducing the joint construction cost. It is possible.
