Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of casting concrete at the bottom of a gutter constructed by a gate-shaped or U-shaped gutter block having an opening for mounting a lid on the upper surface while adjusting the drainage gradient. More particularly, the present invention relates to a method of placing concrete effectively used in a place where a side gutter is curved or a place at a short distance.

[0002]

2. Description of the Related Art Conventionally, it has been difficult to cast concrete in a gutter of this type, particularly when the width is small and deep. The applicant has developed various automatic concrete setting machines to solve this.

[0003]

Conventionally, the casting machine is large in size because the hopper for supplying concrete is integrated, and the construction is easy when the side groove is a straight portion.
When the curve is short or the distance is short, the length of the driving machine is in the way and it is inconvenient. For this reason, when the hopper is reduced in size, the supply of concrete to be supplied becomes frequent and the work may be complicated.

[0004]

SUMMARY OF THE INVENTION The present invention provides a method for placing concrete on a gutter at a curved part or at a bottom part of a gutter at a short distance. A guide for height adjustment according to the drainage channel gradient is provided at the opening, and a gauge guide A provided with a guide for width adjustment to match the width of the gutter block is provided to determine the drainage gradient and width. A guide plate having an L-shaped cross section is disposed at the lower part of the gauge guide A so as to oppose the left and right sides. Concrete is poured, and a leveling tool having a handle and an oyster tool are used in accordance with the L-shaped guide plate to make a rough level. After finishing, it is a method of finishing with a finishing machine and placing concrete on the bottom of the gutter block.

[0005]

Therefore, this construction can be performed for each unit of the gutter block, so that the work can be performed particularly effectively in a curved portion or a place where the distance is short, as well as a leveling tool with a handle, an oyster stick, and this oyster tool. By using a flattening iron or a finishing machine provided with a leveling plate or a finishing blade, concrete can be quickly compacted and finished with high accuracy.

FIG. 1 shows an embodiment in which a lower end of a gauge guide A is mounted along a drainage gradient.

The gauge guide A will be described with reference to FIGS. 1 to 4. The gauge guide A is connected by a pipe-shaped guide (10) connecting two divided width adjusting rods (9). As shown in FIGS. 2 and 3, the adjustment guide (10) slides over the notch step for placing the lid on the reinforcing beam B-2 side of the opening B-1 of the side groove block B and slides the width. Is determined. (11) in the figure is a fixing bolt. Also, a width adjustment rod (9) and a width adjustment guide (10)
Alternatively, other similar methods such as a method of rotating a turnbuckle or the like to determine the width as shown in FIGS. 12 and 15 may be used.

A height adjusting rod (6) is provided at both ends of the width adjusting rod (9) so as to follow the inner surface of the side wall of the side groove block B, and the height adjusting rod (6) is a height adjusting guide (7). ) So that it can slide in the adjustment guide (7), and the adjustment rod (6) can move up and down. Reference numeral (12) in the drawing denotes a fixing screw, and the height adjusting rod (6) and the width adjusting rod (9) are provided at both ends of the opening B-1 of the side groove block and are connected by the joint material (8). In the opening B-1. The adjustment guide (7) can be slid up and down by a similar method such as a screw.

An L-shaped guide plate (1) is attached to the lower end of the height adjusting rod (6) so as to face left and right inside the side wall of the side groove block.

Therefore, the width of the side groove block B is adjusted by the width adjusting rod (9), and the inclination adjustment according to the drainage gradient of the guide plate (1) can be adjusted by the height adjusting rod (6). The lower end of the L-shaped part of the guide plate (1) is a concrete finished surface to be cast, and the bottom surface of the block is adjusted to the level of drainage gradient. A concrete floor is formed.

There are various ways to attach the L-shaped guide plate (1) to the height adjusting rod (6). For example, as shown in FIG. )
A fixing plate (3) is fixed to the lower end of the guide plate (5), a hook-shaped insertion plate (2) is inserted into the fitting plate (3), and the upper end of the L-shaped guide plate (1) is fixed. A guide plate (1) is installed on the inner lower surface of the side groove block B. Since this fitting is performed by insertion, it can be mounted with one touch.

The length of the guide plate (1) is usually 2 m or 1 m so as to be the same as the length of one side groove block B.
And the opposing guide plates (1),
During the period (1), concrete is put in and roughened with a leveling tool or oyster with a handle shown in FIG. 5 and thereafter, and then finishing is performed by a finishing machine.

FIG. 5 shows a curved iron (18) with a handle (1).
6) is mounted in a T-shape, and concrete C is charged while the vibrator is operated, and roughening is performed while compacting. At this time, the concrete C is compacted while adjusting the amount so as to protrude from the upper surface of the guide plate (1), and roughened.

A method for leveling various types of concrete will be described with reference to FIG. FIG. 6 consists of an oyster stick (15) fixed in a T-shape to the handle (16), and a vibrator (17) is attached to the handle (16). The vibrator (17) is operated by placing both ends on the L-shaped surface of the guide plate (1), and the oyster bar (15) is moved back and forth to roughen the surface while scraping excess concrete. (See FIG. 7) Depending on the condition of the concrete slump, this leveling tool or oyster tool may not operate the vibrator or may not be mounted.

Further, the finishing machine shown in FIG. 8 uses a shaved tool having a handle shown in FIG. 6 as shown in the figure, and is followed by a leveling plate (21) and a finishing blade (2).
2) is attached to finish the concrete C while leveling it. By using the finishing blade (22), the concrete surface is finished more smoothly. Reference numeral (20) in the figure is a key-shaped protrusion for engaging the oyster bar (15), and the concrete surface is finished while the oyster bar is engaged with the protrusion. Further, as shown in FIG. 9, this finishing machine can attach a vibrator to the leveling plate (21) as shown in FIG. 9, and the leveling plate (21) is replaced with the leveling plate (21) in FIG. It can also be pulled with a string, etc.

Next, FIGS. 11 to 15 show an embodiment in which a gauge guide A is installed on a U-shaped side groove block B-3. FIG. 11 is a view showing an embodiment in which a gauge guide A is provided on the upper surface of the side wall of the U-shaped side groove block B-3. FIGS. 12 to 14 show U-shaped side groove blocks B-3 having different bottom shapes.
FIG. FIG. 15 is a plan view. Reference numeral (25) in the figure indicates a turnbuckle.

【The invention's effect】

According to the method of placing concrete on the bottom of the gutter according to the present invention, a gage guide A is attached to each unit of the gutter block B, and concrete is poured in, while the concrete is poured and roughened by a leveling tool or oyster with a handle. Since the finishing is performed by using a finishing machine, it can be extremely easily applied to a curve portion of a side groove or a short-distance casting operation.

Further, in the concrete compaction finishing, a leveling tool and an oyster with a handle and an L-shaped guide plate (1) are adapted to the level of the drainage gradient and the leveling tool and the oyster. The tool can be constructed by working while pressing the tool back and forth or up and down, so that it is simple, and an accurate drainage gradient can be formed at the bottom of the gutter because the finishing machine makes it a smooth surface.
