Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a joint material used as a backup material for caulking and sealing in a window frame or a joint portion of an outer wall material, and particularly to a roll joint material that is rolled up until use and rewound during use. .

[0002]

[Prior art]

 Conventionally, a joint material 50 as shown in FIG. 5 has been widely used as a backup material for caulking, sealing treatment, etc. in a window frame of a building or a joint portion of an outer wall material. In the joint material 50, an adhesive layer 53 is provided on one side of an elongated plastic foam body 51, and the surface of the adhesive layer 53 is covered with a release paper 55. Used as. In the figure, 57 is a wall material and 59 is a sealing material.

The joint material 50 is usually sold as a rod having a length of 1 to 2 m or wound in a roll. However, in any case, the release paper has to be peeled off when the joint material is used, which is not only a troublesome work, but also causes a problem that the peeled release paper becomes waste. Especially at construction sites, since a large amount of joint material is used, a large amount of release paper, which is a waste, not only wastes resources but also requires cleaning. In addition, since it is necessary to hold the bundle of jointing material in one hand during the construction work, one hand is blocked and the work is difficult.

[0004]

[Problems to be solved by the device]

 The present invention has been made in view of the above points, and it is an object of the present invention to provide a roll-shaped joint material that does not need to be peeled off the release paper at the time of use, and can hold both hands without closing them.

[0005]

[Means for Solving the Problems]

 In this invention, a joint material main body made of a plastic foam is provided with an adhesive layer on one side, and a joint material having an adhesive and peelable film on the opposite side is attached to the other side of the joint through the arm insertion hole. The present invention relates to a roll-shaped joint material wound around the outer peripheral surface of a cylindrical body having the pressure-sensitive adhesive layer inside.

【Example】

 Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. 1 is a side view of a rolled joint material according to an embodiment of the present invention, FIG. 2 is an enlarged sectional view of 2-2 thereof, FIG. 3 is an enlarged sectional view of the joint material, and FIG. 4 is of another embodiment. It is an expanded sectional view of a joint material.

A rolled joint material 10 of one embodiment of the present invention shown in FIGS. 1 to 4 comprises a joint material 11 and a cylindrical body 21. The joint material 11 comprises a joint material body 13, an adhesive layer 15 provided on one surface thereof, and a film 17 attached to the opposite surface.

The joint material main body 13 is made of a flexible plastic foam such as polyethylene, polypropylene, polyurethane, and ethylene vinyl acetate plastic, and usually has a cross section of about 2 to 25 mm × 2 to 25 mm. It consists of a rectangular strip or strip.

The pressure-sensitive adhesive layer 15 is formed of various pressure-sensitive adhesives, and as an example, a pressure-sensitive adhesive obtained by adding a solvent to an acrylic resin to dissolve it and adding a stabilizer, a filler, and the like is given. The film 17 is used so that it can be adhered to and released from the adhesive of the adhesive layer 15. As the film 17, a flexible plastic such as polyethylene, polypropylene, vinyl chloride, vinylidene chloride, ethylene vinyl acetate-based plastic, etc. is adhered integrally by adhesion or welding or at the time of molding the joint material main body 13. It is formed. The film 17 is preferably a polyolefin-based film from the viewpoint of adhesiveness and releasability with respect to the adhesive, but the adhesive can be formed by making the surface uneven as shown in the figure or providing a number of small holes. May be easily peeled off.

On the other hand, the tubular body 21 is made of a paper-made, plastic-made or metal-made tube having an arm insertion hole 22 having a diameter of 65 to 200 mm at its center, and the joint material 11 is provided on the outer peripheral surface of the adhesive layer. It is wound with 15 inside. At that time, the pressure-sensitive adhesive layer 15 and the film 17 overlap each other, and the joint material 11 is maintained in a roll state by the easy-peeling adhesion between the pressure-sensitive adhesive layer 15 and the film 17. The amount of the joint material 11 on the outer circumference of the cylindrical body 21 is determined in consideration of workability, but normally the outer diameter of the roll-shaped joint material 10 is about 600 mm or less.

When this rolled joint material 10 is applied to a window frame or the like, one worker's arm is inserted into the arm insertion hole 22 of the tubular body 21 and held by the worker. Then, in this state, the joint material 11 is unwound from the tip end, stretched into a rod shape, and cut into a desired length for use. At the time of rewinding, since the film 17 can be peeled off from the adhesive layer 15, the rewinding of the joint material 11 is not hindered.

In a joint material 31 of another embodiment shown in FIG. 4, a plastic foam 34 is attached to the surface of a joint body 33 in place of the film 17. This plastic foam 34 is also made of a material that can be adhered to and peeled from the adhesive of the adhesive layer 35. The plastic foam 34 is preferably a non-polar one such as polyethylene or polypropylene. Further, on the surface of the plastic foam 34, innumerable small holes such as pores or irregularities may be formed to enhance the releasability with respect to the adhesive. The joint material 31 of this embodiment is also rolled into a roll by being wound around the tubular body 21.

[0013]

[Effect of device]

 As shown and described above, according to the roll-shaped joint material of the present invention, since it is not necessary to peel off the release paper at the time of use, the work is simplified and the release paper does not become dust. Furthermore, since the rolled joint material of the present invention is held by the operator when the operator's arm is inserted into the central hole during use, the operator has both hands free and can perform work with extreme precision. Easier to do.
