Abstract

PURPOSE:To perform concrete placing work continuously and reduce construction cost by providing a concrete placing pipe, a leveling blade, a level adjusting mechanism, a vibrating plate, and a rotation mechanism for the leveling blade on a carriage. CONSTITUTION:When a device is moving forward slowly at a construction speed by the driving force of a traveling engine 2e, concrete is supplied from a concrete placing pipe 4. The concrete supplied from the concrete placing pipe 4 is leveled horizontally by the rotation of a leveling blade 3 to complete rough leveling and level setting. The concrete surface comes into contact with a vibrating plate 6 which is vibrated by a vibrator 6a together with advance of the placing and leveling device 1, so that the concrete surface which has been leveled by the leveling blade 3 is made smooth and screeded with a fixed level. It is thus possible to perform a process from the supply of concrete to be placed to rough leveling, level setting, and screeding with a single concrete placing and leveling device 1 so as to improve work efficiency.

[0002]

2. Description of the Related Art Conventionally, in the floor concrete construction in which concrete is poured to form slabs, the steps of pouring concrete, leveling, leveling, ruler cutting, and pressing are sequentially performed. Many of these operations rely on the manual work of each worker, and many workers who carry tools and the like for each process go out to the site.

[0003]

However, in the case of the concrete placing and leveling apparatus as described above, the following problems have occurred. That is, in the construction work, each work is a separate work, and the next work is started after the completion of the previous process, which causes a decrease in work efficiency. In addition, among the above-mentioned works, in particular, placing and roughing of concrete is heavy work, and leveling and ruler slinging must be performed by the worker in a middle waist posture, which is a problem that workability is unsatisfactory. There is also.

On the other hand, the above-mentioned construction requires a skilled worker for each work, and requires a large number of skilled workers to complete the work. Therefore, due to the shortage of specialized workers in recent years, human resources can be secured. In addition to the possibility of extending the construction period due to the difficulty, the labor cost increased, causing the construction cost to rise.

The present invention has been made in view of the above-mentioned problems, and improves the work efficiency and the construction cost by performing each work such as pouring concrete, rough averaging, leveling, and ruler cutting by one unit. It is an object of the present invention to provide a concrete pouring leveling device capable of reducing the noise.

[0006]

In a concrete pouring and leveling device of the present invention, a dolly, leveling vanes attached to the rear part of the dolly and horizontally rotated, and front parts of the leveling vanes are provided. A concrete supply device that is installed and supplies concrete to be poured, a level adjustment mechanism that supports the leveling vanes so that it can move up and down, and adjusts the leveling level, and is installed horizontally at the rear of this level adjustment mechanism. With a vibrating plate, a drive mechanism for rotating the leveling vane is attached to the leveling vane, and a vibrator that vibrates the vibrating plate at a frequency that makes the surface of the concrete before strength development smooth is attached to the vibrating plate. And the concrete pouring and leveling device according to claim 1, wherein the wheel supporting the load of the truck is formed by forming a hollow outer shape with a linear member. It was the solution.

[0007]

According to the concrete pouring and leveling apparatus of the present invention, the work of floor concrete construction and floor board construction from the pouring of concrete to the rough leveling, the leveling to the ruler cutting can be performed simultaneously by one apparatus. It can be done as work. Further, in the above-mentioned pouring leveling device, since the supplied concrete is leveled with the leveling blades while traveling on the floor to be poured, the leveling mechanism adjusts the leveling level of the leveling vanes. This will improve the level accuracy by constructing the entire floor at an appropriate leveling level.

According to the second aspect of the present invention, in the driving and leveling device, the weight of the entire device is reduced, and the wheel having a hollow shape formed by the linear member is used for the carriage. As a result, the weight of the device is reduced, the influence on the level caused by traveling on the poured concrete is reduced, and the construction accuracy is improved.
