  EMBODIMENT OF THE INVENTION Hereinafter, the form for implementing this invention is demonstrated based on Examples 1-3 shown in drawing.

First, the overall configuration of Example 1 will be described.
FIG. 1 shows a schematic configuration of a curable slurry placement apparatus 10 provided with a curable slurry placement hose head 1 of the first embodiment.

  The curable slurry placement apparatus 10 of the first embodiment is for curable slurry via a ball valve 3 serving as an on-off valve on one end side of a cylindrical portion 2 constituting the curable slurry placement hose head 1. A hose 4 extending from the pump P is connected.

  In addition, by operating the handle 3a as the operation part of the ball valve 3, the valve can be closed and the discharge of the curable slurry can be temporarily stopped.

  The hose head 1 for placing a curable slurry according to the first embodiment includes a spatula-shaped receiving portion 5 for receiving the curable slurry discharged from the opening 2a on the other end side of the cylindrical portion 2 on its upper surface. It has a feature.

  As shown in FIG. 2, the spatula-shaped receiving part 5 is joined to the other end of the cylindrical part 2 with screws 6,... It is said that.

  The spatula-shaped receiving portion 5 has standing portions 5a and 5a that rise upward from the left and right edges with the joint portion with the cylindrical portion 2 as the center.

  Furthermore, the spatula-shaped receiving part 5 is flat via a support part inclined from the joint part with the cylindrical part 2.

  Moreover, since the joining part which is a support part of this spatula-shaped receiving part 5 is a thin and thin metal plate, this joining part bends, and the cylindrical part 2 is shown by the dashed-two dotted line in FIG. As described above, the angle can be adjusted in various directions from front to back and from side to side.

  Here, FIG. 5 shows a state in which a floor-like structure is constructed using the curable slurry placement apparatus 10 of the first embodiment.

  As can be seen from FIG. 5, the curable slurry discharged from the opening 2 a on the other end side of the tubular portion 2 of the hose head 1 for placing the curable slurry is received on the upper surface of the spatula-shaped receiving portion 5. Because it is discharged from the ground, there is no risk that the rough floor surface such as the ground surface will be roughened and the soil constituting the rough floor surface will be mixed into the curable slurry, and the original properties of the floor structure to be constructed Can be secured.

  Further, the discharged curable slurry is received by the upper surface of the spatula-shaped receiving part 5 and not only driven after the pressure is reduced, but also splashed laterally by the standing parts 5a and 5a. Because there is a lower risk of smearing the rising parts of walls, etc., or defeating unillustrated landmarks installed on rough floors, you must re-install the landmarks or work with caution. The degree can be further reduced.

  Thereby, as shown in FIG. 6, a floor-like structure Y such as a base material for a floor in a high-quality building or a base material for a precast concrete foundation can be constructed efficiently.

  In addition, as a curable slurry to be cast, a self-leveling material slurry, a cement slurry, a water curable ceramic slurry, a resin slurry, a grout slurry and the like are used as in the past.

Next, the effect of Example 1 is demonstrated.
The curable slurry casting hose head 1 according to the first embodiment has a cylindrical portion 2 to which the hose 4 is connected on one end side, and a curable composition discharged from the opening 2a on the other end side of the cylindrical portion 2. It is set as the structure provided with the spatula-shaped receiving part 5 for receiving a slurry on the upper surface.

  Since it is the above-described configuration, the curable slurry discharged from the opening 2a on the other end side of the cylindrical portion 2 is received on the upper surface of the spatula-shaped receiving portion 5, and is placed after the pressure is reduced. It is possible to ensure the original properties of the constructed floor-like structure Y without roughening the rough floor surface such as the ground surface and without causing the soil constituting the rough floor surface to be mixed into the curable slurry. it can. In addition, since the discharged curable slurry is received by the upper surface of the spatula-shaped receiving part 5 and is placed after the pressure is reduced, the rising part such as the wall surface may be smeared on the rough floor surface. In addition, since there is a low risk that the mark placed on the rough floor will be overturned, the degree of necessity for re-installation or careful work must be reduced, and work efficiency is improved accordingly.

Here, the spatula-shaped receiving portion 5 has a fan shape that spreads outward from the joint portion with the tubular portion 2.
For this reason, since the curable slurry discharged from the opening 2a on the other end side of the cylindrical portion 2 is discharged radially, it is almost received by the upper surface of the fan-shaped spatula-shaped receiving portion 5 to reduce the pressure. In addition, since the supply rate of the curable slurry does not have to be lowered, there is no reduction in work efficiency.

Moreover, the spatula-shaped receiving part 5 has standing parts 5a and 5a on the left and right edges with the joint part with the cylindrical part 2 as the center.
For this reason, since the curable slurry discharged from the opening 2a on the other end side of the cylindrical portion 2 is controlled by the inner surface of the standing portions 5a and 5a, the rising portion such as a wall surface is bounced laterally. The possibility that the mark placed on the rough floor or the mark placed on the rough floor will be further reduced, so that the degree to which the mark must be re-installed or the work must be taken can be further reduced. Work efficiency is even better.

Furthermore, the back surface of the spatula-shaped receiving part 5 is flat.
For this reason, since the surface of the curable slurry after placing can be leveled sequentially using the back surface of the spatula-shaped receiving part 5, it is not necessary to use a tool such as a rake separately, and the workability is increased accordingly. Is good.

Further, the angle of the tubular portion 2 can be adjusted at the joint portion with the spatula-shaped receiving portion 5.
For this reason, the worker can easily perform a wide range of work from one place.

A ball valve 3 as an on-off valve that can be opened and closed by a handle 3a as an operation portion is provided between the cylindrical portion 2 and the hose 4.
For this reason, when the necessary driving amount of the curable slurry can be secured, it is only necessary to close the ball valve 3 with the handle 3a. Therefore, it is not necessary to use an auxiliary tool such as a bucket for receiving the curable slurry.

Such a curable slurry placement apparatus 10 of Example 1 is configured to include the curable slurry placement hose head 1 of Example 1 described above.
Since it is an above-mentioned composition, it can be set as the curable slurry placement device which has the operation effect of hose head 1 for curable slurry placement of Example 1 mentioned above.

Such a floor-like structure Y of Example 1 is constructed by using the curable slurry placement apparatus 10 of Example 1 described above.
Since it is the above-described configuration, it is possible to finish more quickly because of high quality and good work efficiency.
