[Detailed description of the invention] [Industrial field of application] This invention is a trowel for forming wall surfaces such as ceilings.
In more detail, wall surfaces such as ceilings and side walls,
This invention relates to a trowel for forming wall surfaces such as ceilings, which enables quick and smooth construction work and improves work efficiency when finishing with paper or cloth.

[Conventional technology]

There are various structures for the ceiling and wall surfaces of buildings, depending on the type of building, such as walls plastered with mortar or the like, walls covered with board materials, and walls covered with paper or cloth. And, “walls and ceilings finished with paper and cloth”
Traditionally, paper and cloth were attached to the base of the ceiling and walls using the following method.

In other words, form a scaffold that allows you to reach the ceiling,
Apply adhesive to the back side of paper or cloth of a certain standard size, or if it has already been applied, wet it with water and have one worker apply adhesive such as glue to the surface of the wall finishing cloth. Fold the paper or cloth so that it does not stick, lift it up, place it on the ceiling from below, unfold and unfold it one by one, and then the other worker uses one hand to support the paper or cloth from below on the ceiling. At the same time, the paper or cloth was pressed against the ceiling surface using a brush held in the other hand, and the paper or cloth was pasted on the surface under the ceiling while expelling air.

The brush used for the above-mentioned lamination was an ordinary brush with densely planted bristles, which was held in one hand and quickly moved back and forth from side to side while moving forward to lather.

[Problem that the invention attempts to solve]

However, in the method of laminating using a brush, the brush must be moved back and forth many times to perform lamination, which is not only labor intensive but also has the problem of poor work efficiency. .

Therefore, the present invention was devised to address the above-mentioned problems, and its main purpose is to enable quick and smooth lamination work and to significantly improve work efficiency. An object of the present invention is to provide a pasting trowel for forming ceiling and wall surfaces.

[Means for solving problems]

The trowel for forming walls such as ceilings according to the present invention as a means for achieving the above object forms left and right wings that are inclined at a desired angle in the left and right direction with the top as the border, and the upper surface of the central portion is A handle is provided, and all or part of the bottom surfaces of the left and right wings are implanted with hairs to form a brush shape.

In addition, the central part of both the left and right wings is formed at least into a cavity, and a release hole communicating with the cavity is provided on the upper surface of the central part, the inclination angle is about 5 degrees, and the main body of the iron is approximately semicircular in the central part. It is also possible to form a configuration in which the left and right wings are each formed to be adjustable in length, and all or part of the left and right wings are hollow.

[Effect]

The trowel for forming a wall surface such as a ceiling of the present invention based on the above structure is grasped by the handle with the brush surface facing upward. The brush surface is then brushed against a piece of cloth spread on the ground beneath the ceiling and moved forward. By doing so, the right and left wings, which are tilted at a desired angle in the left and right directions with the top as the border, allow the trowel to move forward smoothly, and while the air between the base surface and the fabric is exhausted, the fabric is closely placed under the wall. It acts like it is attached to the ground.

As described above, the adhesive trowel for forming wall surfaces such as ceilings of the present invention is characterized by being formed with both left and right wings that are inclined at a desired angle in the left and right direction with the top as the border. This has the effect that wallpaper etc. can be laminated smoothly.

〔Example〕

Hereinafter, embodiments embodying the present invention will be described with reference to the drawings.

Here, FIGS. 1 to 4 show examples of the present invention,
Figure 1 is a bottom view, Figure 2 is a top view, and Figure 3 is a bottom view.
The cross-sectional view taken along the line A-A in FIG. 4 is an explanatory view of the state of use.

Roughly speaking, the adhesive trowel for forming walls such as ceilings in this embodiment has left and right wings 1 and 1' that are inclined at a desired angle in the left and right directions with the top as the border, and a hollow 2 in the center, with an open hole. 3, a handle 5, and a brush 6.

Both the left and right wings 1, 1' are inclined at about 3 to 5 degrees with respect to the imaginary line L, and the top portions are rounded. Here, the reason why the angle is set at 3 to 5 degrees is to deal with the fact that if it is 2 degrees or less, the resistance to advance is large and it cannot be bonded smoothly, and if it is 6 degrees or more, it is difficult to advance. This was done in consideration of the results of trial production and construction, which showed that laminated wallpaper and cloth tend to wrinkle and tear easily. Normally, the length between the ends of the left and right wings 1 and 1' is 90 cm, the width is 7 cm, and the thickness is
It is 2.5 cm, and the length between the two ends can be adjusted by preparing a number of long and short detachable adapters 7. However, the size and shape can be selected arbitrarily. The insides of both the left and right wings 1, 1' are formed into a substantially hollow shape.

The iron main body part 4 has a substantially semicircular center portion of both left and right wings 1, 1', and a hollow 2 inside.
A circular release hole 3 is provided on the top surface and communicates with the cavity 2. This main body is formed with consideration given to stability during work, and is designed to prevent the tips of the left and right wings 1 and 1' from being tilted forward and damaging the pasted wallpaper, etc. This is a measure that deals with things such as eliminating people. Usually, the width is about twice the width of the left and right wings 1, 1'.

The handle 5 is provided so as to be in contact with the circular release hole 3 so as to be partially cut out, and is in a state of protruding downward from the bottom surface of the central portion. Furthermore, the handle may be configured to be horizontally rotatable, if necessary.

The brush 6 has bristles densely planted all over the bottom surface of the left and right wings 1, 1' and the center portion of the iron main body 4. However, it is not necessary to implant the hairs all over the entire surface; for example, they may be arranged in one or two rows at the tips and rear ends of the left and right wings 1 and 1', and in a horizontal row in the center of the main body. good. That is, a configuration may be adopted in which a plurality of rows are arranged parallel to the forward direction. Also, brush 6
The structure may be made of a material such as artificial turf. And the thickness of the brush (grass) is
Although the thickness is about 0.5 to 3 cm, it is clear that other thicknesses are also possible.

The material of the trowel is a processed product such as wood or synthetic resin. Further, the adapter 7 can be attached and detached by either an insertion type as shown by the dotted line in the embodiment, or a fitting type.

Next, to describe the operation of this embodiment, two workers are on a scaffold, and one worker is holding a sheet-like ceiling made of a thin material woven from chemical fiber or the like and lined with paper. Using wall finishing material 8 or plastic, the finishing material 8 processed into a sheet shape is folded as shown in FIG. 4, and spread on the ceiling surface 9 from one end.
In this case, since the adhesive has been applied to the finishing material 8 in advance, it can be temporarily bonded to the ceiling base surface 9 simply by applying water. In addition, the edges of the finishing material 8 are neatly cut with a cutter, and the sheet-like finishing material 8 is sequentially joined so that there is no slack or discrepancy in the pattern. Then, one worker spreads the finishing material 8 on the ceiling subsurface 9 (temporary fasteners may be used in this case). Insert your finger into the cavity 2 through the hole 3, grasp the handle 5 with your thumb, and remove the brush 6.
When it is pressed against the sheet-shaped ceiling wall finishing material 8 and moved in the forward direction (in the direction of arrow a), the finishing material 8 is neatly stretched and bonded to the ceiling subsurface 9, and air is also expelled to form a close bond. act so that it is done.

In other words, the worker who is responsible for spreading the sheet-shaped ceiling wall finishing material 8 and the worker who is responsible for adhering the finishing material 8 closely together, the worker who is responsible for adhering the finishing material 8 closely, The laminating operation can be performed quickly and reliably by simply pushing the pasting trowel 10 of this embodiment forward.

Further, due to the effect of the large trowel area of the semicircular trowel main body 4, the pressing contact state of the trowel 10 against the ceiling wall finishing material 8 acts stably.

It should be noted that the present invention is not limited to the embodiments described above, and it is clear that modifications can be made without changing the gist of the present invention. Incidentally, it can be applied not only to ceiling walls but also to regular walls.
In this case, if the direction of the handle 5 can be changed,
It becomes possible to hold the device in various ways, and the bonding work can be performed in a more comfortable posture.

[Effect of idea]

As is clear from the above description, the adhesive trowel for forming walls such as ceilings according to the present invention has the effect that the adhesive work can be performed quickly and reliably, and the work efficiency can be improved.

In addition, according to the adhesive trowel for forming walls such as ceilings of the present invention, since both wings are inclined at an appropriate angle of about 3 to 5 degrees, there is no risk of damaging paper or cloth, and the main body of the trowel in the center This has the effect of allowing stable work.
