Abstract

PROBLEM TO BE SOLVED: To improve quality of execution of levelingly paving asphalt and to improve the efficiency by making a pushing plate up and down slidable against a regulating plate, and fixing rule plates to the regulating plate. SOLUTION: A pushing plate 1 is fitted with bolts and piled on a regulating plate 4 to be fastened with thumbscrews 3, and the pushing plate 1 is made up and down slidable against the regulating plate 4. Further rule plates 2 are fixed to the regulating plate 4, a rod 5 is provided on the center part of the regulating plate 4, and hence a paving rake with rule is constituted. At first scattering thickness is decided against thickness of pavement, the dimension is measured with the lower ends of the rule plates 2 and the lower end of the pushing plate 1, and the thumbscrews 3 are fastened to set the paving rake. Next, a proper quantity of asphalt mixed material is dropped on the road bed surface, and it is spread by a customary rake and the like. Next by pushing the road bed surface by the paving rake with rule, it is correctly leveled and laid at the set thickness. Hereby quality of execution can be improved, and the efficiency can be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rake which is used for asphalt pavement in which unusable parts of a machine are used for leveling by manpower.

[0002]

2. Description of the Related Art A conventional rake is formed by attaching a handle to a single pressing plate at a right angle and has been used for a long time, and is convenient. In the case of paving, the thickness was unstable and waste occurred.

[0003]

In the conventional flattening with a rake, it is difficult to make the thickness constant, and it is necessary to visually judge the finish.

[0004]

In order to solve this problem, the present invention will be described with reference to a diagram in which a rule is attached to a rake in order to keep the thickness constant. Overlap (4) and tighten with thumbscrew. The adjustment plate (4) is provided with a vertically long screw hole so that the push plate (1) can slide up and down. Furthermore, a ruler plate is fixed to the adjustment plate to form a single body, and the roadbed surface slides back and forth. And attach the handle to the center of the adjustment plate

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In using the present rake, first, a spout thickness is determined with respect to a pavement thickness, and the dimensions are measured at the lower end of a ruler plate (2) and the lower end of a push plate (1), and a thumb screw is used. To set. Next, an appropriate amount of asphalt mixture is dropped on the roadbed surface and spread with a conventional rake or the like. Then, if the rake according to the present invention is pressed while sliding on the road surface, the rake of the rake according to the present invention is accurately spread to the set thickness. This is done repeatedly by paving, and then rolling with rollers etc. to finish

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Although the advancement of machinery has been enhanced by the development of technology, large-area pavements are made by machinery, but nevertheless, manual paving is always accompanied.
Use of the present invention saves accuracy and waste

[0007]

As described above, although the paving machine has advanced, the method of leveling by manpower is still an old method. The use of the present invention improves the quality of enforcement and improves efficiency and contributes to the industry.
