Abstract

(57) [Summary] [Purpose] To provide a comb iron with good workability in which tiles are not displaced and bonded. A comb trowel 1 having a smooth flat surface portion 3 and a comb portion 2 in which a comb is formed, the comb portion 2 being inclined with respect to the flat surface portion 3.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an adhesive used for adhering tiles, outer wall materials and the like to a body and a comb iron for mortar construction.

[0002]

[Prior Art]

 When the inner and outer tiles, the outer wall material and the like are adhered by applying an adhesive or mortar to the body, the comb iron 8 having the comb portion 9 as shown in FIG. 6 is used.

The comb trowel 8 is a plate-like body having a smooth flat surface portion 10, and is provided with comb-like portions 9 and comb-free portions 11 in which no comb is formed on the opposite side edges thereof, respectively. A gripping portion 12 for gripping the comb iron 8 is provided in the center. For example, as shown in FIG. 7, the comb portion 8 has a shape in which a 5 mm square notch 13 and a 5 mm square protrusion 14 are alternately formed.

In order to make a comb using this comb trowel 8, first, an adhesive or mortar is smoothly applied using a comb-free portion 11 in which no comb is formed, and then the comb 9 is formed. The tip is brought into contact with the skeleton 15 to tilt the comb iron 8 at an arbitrary angle, for example, as shown in FIG. 8, it is tilted to the comb angle β (the tilt of the comb portion 9 with respect to the core 15), and the comb iron 8 Pull in the direction of the arrow to make a comb. By thus providing the adhesive layer 16 or the mortar layer with a comb, sufficient adhesive strength can be obtained without leaving an air residue on the surface of the tile or the like.

[0005]

[Problems to be solved by the device]

However, in the above method, even if the shape and size of the comb are determined, the comb angle of the comb iron at the time of coating varies greatly depending on the operator, and as a result, the coating thickness of the adhesive or mortar also varies. Further, in order to obtain a required coating amount (eg, 1.5 kg / m ² ), in the case of the same comb iron, the comb angle of the comb iron must be increased, which requires more labor than smooth coating. Therefore, there is a problem that workability is deteriorated.

If the application amount of the adhesive or the mortar varies, or if the application amount is less than the required application amount, the tiles are displaced and adhered to the body. The present invention has been made in view of the above points, and an object thereof is to provide a comb trowel with good workability, in which tiles are not misaligned and bonded and can be uniformly combed.

[0007]

[Means for Solving the Problems]

 The comb iron of the present invention is a comb iron having a smooth flat portion and a comb portion formed with a comb, and the comb portion is inclined with respect to the flat portion. It is a feature.

It is desirable that the inclination be an inclination angle of about 130 to 170 °.

[0009]

[Action]

 Since the comb section is inclined with respect to the flat section, if the flat section is parallel to the body, the comb section will be placed inclining with respect to the body in advance. Even if it is not greatly inclined, the comb portion will be greatly inclined with respect to the body.

For this reason, the operator does not have to incline the comb iron with respect to the skeleton significantly, but the comb portion can be greatly inclined with respect to the skeleton, and a large amount of coating amount can be combed. The workability is improved as well.

Further, since it is less likely that the coating amount is smaller than the required coating amount, defects such as a deviation of the tile are reduced.

[0012]

【Example】

 The present invention will be described below with reference to the drawings showing an embodiment thereof. FIG. 1 is a perspective view of an embodiment of a comb iron of the present invention. 2 is a cross-sectional view taken along the line AA of FIG. 1, FIG. 3 is a cross-sectional view taken along the line BB of FIG. 1, and FIG.

The comb iron 1 comprises a comb portion 2 and a flat portion 3, comb side portions 4 and 4 are provided on the side edges of the flat portion 3, and a grip portion for gripping the comb iron 1 in the central portion. 5 are provided.

The comb portion 2 of the comb trowel 1 is inclined at an inclination angle θ of 150 ° with respect to the flat surface portion 3. In the present embodiment, as shown in FIG. 4, the comb portion 2 is formed with a 5 mm square notch 6 and a 5 mm square protrusion 7 alternately.

In this embodiment, the comb portion 2 is provided at two positions on the side edge portion of the flat surface portion 3, and the comb portion 2 at the narrow portion can be applied to a narrow surface such as a corner portion. , There may be only one place.

FIG. 5 is an explanatory view showing a use state of the comb iron of the present invention, in which the comb iron 1 having an inclination angle θ150 ° has an iron angle α (inclination of the plane portion 3 with respect to the body 15) of 10 °. The mesh angle β (inclination of the comb portion 2 with respect to the skeleton 15) is 40 °, showing a state in which a comb is formed.

Combing with the comb iron 1 is performed by pulling the comb iron 1 in the direction of the arrow. Reference numeral 17 is an adhesive layer. Actually, using this comb iron 1 (example) and the conventional comb iron 8 (comparative example), different workers carried out comb weighting work. Table 1 shows the application amount, tile deviation, and workability results.

[0018]

[Table 1]

Since the conventional comb iron 8 of the comparative example has the comb portion 9 formed on the same plane as the plane portion 10, the iron angle α and the comb angle β are equal. The comb height h depends on the comb angle β. Workability is a sensory evaluation of the workability of a worker when the worker combs it.

When the comb iron 1 of the present invention is used, the workability is good, and the required coating amount is 1.5 kg / m. ² Is obtained, and there is no misalignment of tiles. When the conventional comb iron 8 is used, the required coating amount is 1.5 kg / m²However, the workability is poor. In the case of the workers E and F, since the comb angle β was small and the coating amount was small, the workability was only good.

[0021]

[Effect of the device]

 Since the comb portion is inclined with respect to the flat surface portion, the comb portion can be largely inclined with respect to the skeleton even if the comb iron is not largely inclined.

Therefore, the operator does not have to incline the comb iron with respect to the skeleton significantly, but the comb portion is greatly inclined with respect to the skeleton, and a large amount of coating amount can be combed. The workability can be improved as well.

Further, since the coating amount less than the required coating amount is less likely to occur, the defects such as the displacement of the tile are less likely to occur.
