Description

[Detailed Description of the Invention] (Industrial Application Field) This invention is a coating for applying an adhesive to the floor surface of a building when a floor surface interior material such as carpet or linoleum is attached to the floor surface. It is about a spatula.

(Prior Art) When a flooring material such as a carpet is attached to the floor of a building, a lump of high-viscosity adhesive is placed on the floor, and the worker manually or spreads it with a metal spatula rotated by a motor. While applying. As the above metal spatula, for example, as shown in FIG. 3, a trapezoidal spatula 1 having a plurality of triangular or trapezoidal recessed grooves 1a in its linear edge portion at the lower edge is provided. What was engraved in the shape was used. In addition,
In the example of FIG. 3, the upper edge 1b is bent and fixed to the lower surface of the horizontally rotating disc 2 with bolts 3 and nuts 4.

(Problem to be Solved by the Invention) Since the conventional spatula 1 is one in which a large number of relatively shallow concave grooves 1a having a triangular or trapezoidal shape are carved at a straight edge portion at a constant size and at a constant pitch, Types of floors and interior materials,
In order to increase / decrease the amount of adhesive applied depending on the type of adhesive, etc., it is necessary to prepare various types of spatula with different sizes and pitches of the groove 1a and select spatula 1 according to the purpose. If the edge wears out due to use, the groove 1a
However, there is a problem that the coating amount is reduced and the coating amount is reduced.

The present invention provides a spatula for applying a floor adhesive in which the amount of adhesive applied can be easily adjusted.

(Means for Solving the Problem) In this invention, as shown in FIGS. 1 and 2, a large number of concave grooves 12 provided along a straight edge portion 11a of a spatula 11 are formed in a width b. The depth h is larger than that of this groove.
An adhesive tape 13 having an adhesive adhesive coating layer on one surface is adhered to one surface of the comb tooth portion where 12 are arranged so as to cover the bottom 12a side of the groove 12.

In addition, as the adhesive tape, an adhesive tape for packaging in which an adhesive adhesive is applied to one surface of a woven tape is preferable. The groove is preferably rectangular with a width of 1 to 1.5 mm and a depth of 5 to 15 mm.

(Operation) The bottom 112a side of the concave groove 12 is covered with the adhesive tape 13 attached to the comb-shaped portion of the spatula 11, and the edge 13a of the adhesive tape 13 on the side close to the edge 11a is the bottom 12a of the concave groove 12. It becomes the shape that raised. Therefore, the working depth of the concave groove 12 is adjusted by cutting the portion of the adhesive tape 13 covering the concave groove 12 along the edge 13a by a desired width. Then, when spreading the lump of adhesive placed on the floor with the spatula 11 for application, by directing the stretched surface of the adhesive tape 13 toward the lump of adhesive, the edge 13a of the adhesive tape 13 serves as the bottom of the groove 12. The adhesive is spread in a streak shape having a height corresponding to the position of the edge 13a, which functions without any trouble. If the groove 12 has a rectangular shape with a uniform width, the cut width of the adhesive tape 13 is proportional to the amount of adhesive applied, and the cut width can be set easily.

(Example) As shown in FIG. 1 and FIG. 2, a steel plate having a heat of about 0.55 mm was cut into a trapezoid to form a coating spatula 11, and a bottom edge 11a had a width b of 1 mm and a depth of 1 mm. The concave groove 12 having a height h of 10 mm was formed in a comb tooth shape at a pitch of 6 mm. Then, an adhesive tape 13 for packaging was adhered to one surface of the comb tooth-shaped portion where the grooves 12 were lined up to cover most of the grooves 12 on the bottom 12a side. The upper edge 11b
The notch 14 provided in is for inserting the mounting bolt.

In the above structure, the adhesive tape 13 is attached to the lower one-dot chain line M
When the cutting is performed along the line and the lower side portion is peeled off, the working depth of the concave groove 12 increases, and when the cutting is performed along the upper dashed line N and the lower side portion is peeled off, the working depth of the concave groove 12 is increased. Will increase further.

(Effect of the Invention) This invention is one in which a large number of grooves are provided on the edge portion of the coating spatula and an adhesive tape is applied to one surface of the comb tooth-shaped portion to cover the groove bottom side of the groove. When an adhesive spatula is used to spread the adhesive in a number of streaks, the lower edge of the adhesive tape (the edge near the edge of the spatula) determines the thickness of the adhesive applied. Therefore, by cutting the lower edge of the adhesive tape over a desired width according to the floor surface of the building, the interior material, the type of the adhesive, etc., it is possible to apply the adhesive in a streak pattern of a desired thickness. Therefore, it is not necessary to prepare many kinds of coating spatula having different groove depths as in the conventional case. Further, when the edge portion is worn and the adhesive coating thickness becomes thin, the coating thickness can be restored by cutting the edge of the adhesive tape in the same manner.
