  Moreover, the spreader of the present invention may have a structure in which the hopper can be detached from the sliding member.

  With such a structure, it is possible to perform rub pavement immediately by attaching a hopper to the sliding member on the side used for rub pavement. Moreover, work efficiency can be raised by selecting suitably the hopper which can store the quantity of pavement materials required for rubbed pavement.

  Further, the pavement method of the present invention includes a step of attaching the spreader to the moving device, a step of transferring the spreader from the upper stage to the lower stage of the step, a step of putting the pavement material into the hopper, And supplying the pavement material through a gap formed by the sliding member and the step, and laying the pavement material on the step formed on the road surface to rub the step. Is a pavement method for leveling.

  According to such a configuration, the chute is bridged from the upper stage to the lower stage of the step, and after the pavement material is put into the hopper, the chute is moved along the step, thereby paving from the gap formed between the lower side of the chute and the step. The material is supplied to the step. Thereby, it is possible to perform the pavement by rubbing on the level difference by a simple method.

  According to the spread leveling device of the present invention, it is possible to level and level the pavement material on the level difference. As a result, it is possible to rub and pave easily and more quickly than to perform rubbed with human power. In addition, since the pavement material is less likely to harden due to a decrease in temperature, the construction surface is not roughened and high quality rubbed pavement with a finished surface can be performed.

  According to the rubbing pavement method of the present invention, it is possible to perform rubbing pavement on a step in a simple step, so that the construction cost can be reduced. In addition, temporary traffic regulation can be easily released. As a result, traffic congestion associated with the construction can be reduced.

Next, while explaining the operation of the spreader 1 according to the first embodiment, a rubbed paving method using the spreader 1 according to the first embodiment will be described with reference to the drawings as appropriate.
In addition, in drawing to refer, FIG. 5 is the schematic which shows the condition after rubbed pavement.
Here, as shown in FIG. 1, the explanation will be made based on the spreader 1 on the step G side.

First, the spreader 1 is attached to the blade B of the backhoe M.
As shown in FIG. 2, the spreader 1 is attached to the end of the blade B. More specifically, the sliding member 30 and the fixing portion 50 are rotated by inserting the metal rod 512 of the fixing portion 50a into the cylindrical metal member 35 provided on the first sliding member 31a of the spreader 1. It is united freely. Furthermore, the hole W1 provided in the metal plate 513 of the fixing portion 50a and the hole W2 used when lifting the backhoe M are connected by the single pipe 60. In the first embodiment, as shown in FIG. 1, a single pipe pipe 60 straddling the fixed portion 50a attached to the sliding member 30 of each of the spreader 1 and spreader 1 ′ is vertically moved. Two are connected.
The attachment method is not limited to this, and can be changed as appropriate, for example, by connecting with bolts.

Next, the floor leveling device 1 to be used is assembled.
As shown in FIG. 2 and FIG. 4, the sliding device 30 is rotatable about the metal rod 512, so that the first sliding member 31a is rotated so as to be parallel to the step G (see FIG. 1). After the movement, the support bar 51 attached to the fixing portion 50b and the first sliding member 31a are fixed. Since the support rod 51 does not expand or contract, the fixing portion 50b is moved in the long side direction of the blade B by turning the tightening knob 514 of the fixing portion 50b, and the position is adjusted as appropriate. The member 31a is connected.
In addition, as shown in FIG.1 and FIG.4, the floor spreading apparatus 1 'which is not used can be folded and fixed to the braid | blade B. FIG. Thereby, it is possible to prevent the floor leveling apparatus 1 ′ that is not used from interfering with work.
In the first embodiment, the spreader 1 is used. However, if the step G is on the opposite side of FIG. 1, the spreader 1 ′ can be used. As a result, rubbed paving is possible regardless of whether the step G is on the left or right.

Next, as shown in FIG. 3, the attached spreader 1 is set at the step G. At this time, the slide guide 40 is installed so as to abut the protruding corner E of the step G. By installing the slide guide 40 so as to contact the protruding corner E, the lower side J of the short side wall 32 is bridged from the upper stage U to the lower stage L of the step G, and the lower side J of the short side wall 32 is stepped. A gap S is formed with G.
By providing the first guide 41, it is possible to make it difficult for the second sliding member 31b to fall off the upper stage U of the step G. Further, by providing the second guide 42, it is possible to prevent the spreader 1 from slipping into the upper stage U of the step G and spilling the pavement material V on the existing road surface. Thereby, the pavement material V can be easily supplied to the level difference G.

  After the spread leveling device 1 is installed at the protruding corner E of the step G, the pavement material V (see FIG. 3) is put into the hopper 10. In the first embodiment, since the spreader 1 is attached to the backhoe M, the pavement material V is stored to some extent in the hopper 10 by using the bucket P (see FIG. 1) from a truck or the like placed on the backhoe M. Insert until

Next, the backhoe M is moved along the step G.
More specifically, as shown in FIG. 5, as the backhoe M moves along the step G, the sliding member 30 attached to the blade B also moves along the step G. And the pavement material V is supplied to the road surface from the clearance gap S (refer FIG. 3) formed by the lower side J and the level | step difference G of the short side wall 32 of the sliding member 30 because the sliding member 30 moves. Thereby, the level difference G can be rubbed.
In the first embodiment, since the support bar 51 supports the spreading device 1, the spreading device 1 is less likely to wobble during construction.

Here, as shown in FIG. 3, a rubbed shape is already formed between the lower side J of the short side wall 32 of the sliding member 30 and the step G. That is, if the sliding member 30 moves, the pavement material V is automatically spread and rubbed to the step G by the lower side J of the short side wall 32 of the sliding member 30 (see FIG. 5).
Moreover, in 1st Embodiment, as shown in FIG.1 and FIG.2, the 2nd guide 42 is attached to the advancing direction front side from the inner center lower part of the 2nd sliding member 31b. Here, since there is a gap between the short side wall 32 at the rear part in the traveling direction D and the second guide 42, the short side at the rear part in the traveling direction D can be obtained even if the sliding device 30 is moved and rubbed. The pavement material V (see FIG. 3) is supplied between the side wall 32 and the second guide 42, and no groove is formed in a part of the pavement after construction. Thereby, it is possible to perform rubbed pavement which is beautiful in appearance.
In addition, the attachment position of the 2nd guide 42 is not restricted to this, It can change suitably.

After the pavement material V is rubbed against the step G, the worker compacts it with a compacting machine such as a tamper, whereby the rubbed pavement is completed.
As a result, the pavement can be rubbed more quickly and easily than in the case where a conventional worker manually performs the operation, and the working time can be shortened. Further, since the traffic regulation can be released early, it is possible to alleviate the traffic jam and to prevent the tire from coming into contact with the step G and being damaged.

  The present invention is not limited to the above embodiment, and may be the following embodiment.

<< Second Embodiment >>
