Description

The present invention relates to a plastering trowel used when leveling concrete placed on a foundation or floor.

Generally, in the work of pressing the concrete placed on the foundation or floor with gold trowel (floor concrete direct leveling finish), the work of using a plasterer's trowel to widely level the surface of the soft ready-mixed concrete at the time of putting in is used. Work such as leveling the concrete surface at the beginning of solidification is performed.

Conventionally, these works are carried out using a single iron, but especially when the concrete is in a semi-solidified state, aggregates such as gravel rise from the concrete surface and an uneven surface is generated, so especially the finished surface is used. Patent Document 1 describes a concrete finishing gravel configured to be evenly leveled.

That is, since the concrete immediately after casting is soft, even if it is flat at the time of leveling with the gold iron surface, when the cement starts to harden with the passage of time, the mixed gravel etc. will rise from the concrete surface and an uneven surface will be generated. .. Therefore, in the finishing trowel described in Patent Document 1, a large number of through holes smaller than the size of aggregate such as gravel are arranged on the trowel plate to flatten the uneven surface that emerges on the semi-solidified concrete surface. It is configured to level.

However, in the finishing iron described in Patent Document 1, a normal iron and a finishing iron are used properly, so that the worker always needs to prepare two irons.

Moreover, when the cement gradually hardens with the passage of time, the concrete casting surface does not have a uniform effect. Therefore, since the cured state is uneven, the work of replacing the finishing iron according to the cured state may be extremely troublesome.

Therefore, the present invention was devised to solve the above-mentioned problems, and in the work of pressing the concrete placed on the foundation or floor with a trowel, the work of widely leveling the soft ready-mixed concrete and the concrete that is beginning to harden. The purpose is to provide a plasterer's trowel that can rationally finish the surface with a single trowel.

In order to achieve the above object, the first means in the present invention is to use a plastering trowel having a trowel handle on the upper surface side of the trowel plate 1, and to use the trowel handle with different heights of the upper trowel handle 3 and the lower trowel handle. It is in the composition of 4.

It is assumed that the lower grip handle 4 of the second means is fixed to the support leg 5 erected on the upper surface side of the trowel plate 1.

The upper grip handle 3 of the third means is supported by a support leg 6 provided on the lower grip handle 4.

The upper grip handle 3 of the fourth means is formed longer than the lower grip handle 4.

According to claim 1 of the present invention, in the plastering trowel provided with a grip handle on the upper surface side of the trowel plate 1, the grip handle is composed of an upper grip handle 3 and a lower grip handle 4 having different heights. The upper grip handle 3 is suitable for the work of widely leveling soft trowels. On the other hand, the lower grip handle 4 is suitable for finishing the concrete surface at the beginning of solidification. As a result, the work of widely leveling the soft ready-mixed concrete and the work of finishing the concrete surface at the beginning of solidification can be rationally performed with a single iron.

Further, when the cured state of the placed cement is uneven, the upper grip handle 3 and the lower grip handle 4 can be selected according to the cured state, so that rational use suitable for the site becomes possible.

According to claim 2, since the lower grip handle 4 is fixed to the support legs 5 erected on the upper surface side of the trowel plate 1, pressure can be applied to the concrete surface through the lower grip handle 4. Therefore, it is suitable for leveling the concrete surface that has begun to harden.

According to claim 3, the upper grip handle 3 is supported by the support legs 6 provided on the lower grip handle 4. Therefore, the operation with the upper grip handle 3 can level a wider range than the operation with the lower grip handle 4. Therefore, it is suitable for the work of widely leveling soft ready-mixed concrete.

As in claim 4, the upper grip handle 3 is formed longer than the lower grip handle 4, so that the operating range of the trowel plate 1 can be further expanded. Therefore, the work of widely leveling the soft ready-mixed concrete is performed in a wider range. Will be possible.

As described above, according to the present invention, the original purpose of being able to rationally perform the work of widely leveling the soft ready-mixed concrete and the work of finishing the concrete surface at the beginning of solidification has been achieved with one iron.

It is a perspective view which shows one Example of this invention. It is a side view which shows the use example of this invention. It is a side view which shows the other use example of this invention. It is a side view which shows the other embodiment of this invention.

Hereinafter, the present invention will be described in detail with reference to the drawings. The iron of the present invention is an iron used to hold down concrete placed on a foundation or a floor surface with a gold iron. This type of trowel has a grip handle provided on the upper surface side of the trowel plate 1.

In the present invention, this grip handle is composed of an upper grip handle 3 and a lower grip handle 4 having different heights. The upper grip handle 3 and the lower grip handle 4 are arranged one above the other with a gap (see FIG. 1).

That is, the support legs 5 erected on the upper surface side of the trowel plate 1 support and fix the lower grip handle 4, and the support legs 6 fixed on the lower grip handle 4 support and fix the upper grip handle 3. In the illustrated example, a pair of front and rear support legs 5 are fixed on the back metal 2 on the trowel plate 1, and a pair of front and rear support legs 6 separate from the support legs 5 are fixed to the front and rear on the lower grip handle 4. .. It is also possible to form the support leg 5 and the support leg 6 with the same member so that the support leg 6 penetrates the lower grip handle 4.

Further, the support leg 5 and the support leg 6 are formed of the same strip-shaped member (not shown), and the pair of front and rear support legs 5 and the support leg 6 fixed to the upper side of the trowel plate 1 have a lower grip handle. It is also possible to fix the 4 and the upper grip handle 3 at an arbitrary height.

Further, it is possible to change the configuration so that the number of support legs 6 provided on the upper surface side of the lower grip handle 4 is one and the upper grip handle 3 is supported by the one support leg 6. As described above, the positions and numbers of the upper grip handle 3 and the lower grip handle 4, or the fixing means by the support legs 5 and 6 are not limited to the illustrated examples, and the design can be changed arbitrarily.

Since the upper grip handle 3 is separated from the trowel plate 1, it is used for the work of widely leveling the soft ready-mixed concrete at the initial stage of concrete placement (see FIG. 2). Therefore, the longer the upper grip handle 3 is, the wider the range can be adjusted. The upper grip handle 3 shown in FIG. 4 is formed longer than the length of the lower grip handle 4. That is, the upper grip handle 3 is configured so that the trowel plate 1 reaches a position farther from the worker by extending the rear end portion.

The lower grip handle 4 is used for finishing the surface of concrete that has started to harden after a lapse of time from the concrete placement (see FIG. 3). That is, by applying pressure to the lower grip handle 4 close to the trowel plate 1 to acclimatize the surface of the concrete that has begun to harden, it is possible to efficiently level the uneven surface that is raised from the concrete surface.

The embodiment of the present invention is not limited to the illustrated example. The shape, material, etc. can be freely changed without changing the gist of the present invention.
