Abstract

PURPOSE: A flattening structure of a screed for a concrete flattening device is provided to flatten placed concrete using the vertical vibration of a vibration plate. CONSTITUTION: A flattening structure of a screed for a concrete flattening device comprises a flattening device, a vibration unit, a connection member, and a residual concrete removal unit(40). The vibration unit is formed on the first and second of the flattening device and flattens concrete. The connection member is composed of first and second connection members(31,32). The first and second connection members connect the flattening device and the vibration unit to each other. The residual concrete removal unit is formed on the rear surface of the vibration unit and removes remains from the concrete before the vibration unit flattens the concrete.

The present invention relates to a screed flattening structure of a concrete flattening device, and more specifically, to a concrete flatworking device for flattening the floor surface of concrete, such as a building and a road, such as a large building or a shopping mall It relates to a lead planarization structure.

As a method of flattening the surface of concrete laying for floor plastering, it has been conventionally performed by using manpower or foreign laser equipment, and there is no trend in domestic technology development of concrete placing.

At present, the screed and grinding equipment needed for flattening of casting is entirely dependent on imports.In the early 2000s, when the introduction period, there was some demand from large general construction companies, but it was not the main process in the construction market but it was plastering and finishing. The flattening works are mostly small companies with less than 100 million won in capital by the construction contract method that gives subcontracts back to the subcontractor.In the domestic concrete pouring market, most of them are apartments and houses. Since most of them have problems in applying laser leveling screed equipment produced in developed countries.

In order to solve the problems as described above, in the present invention is provided with a vibrating portion on the front surface of the flat work device to flatten the concrete pouring surface, flattened by the vertical vibration of the diaphragm driven by the motor to the casting surface removed from the residual concrete removal unit It is an object of the present invention to provide a screed flattening structure of a concrete flattening device to be poured.

In the construction for achieving the object, in the screed flattening structure of the concrete flattening device that is connected to the connecting member consisting of the first and second connecting members of the vibrating unit on the front of the flat working device, the vibrating unit is the end of the first connecting member A pair of support brackets are positioned at the center and fastened by bolts and nuts. A pair of support brackets is inserted into the front and rear ends of the pair of support brackets so that the connecting rods are positioned side by side in the horizontal direction. Is provided, the lower portion of the guide member is provided with a bracket, the bolt is fastened to the cover provided on the upper surface of the angle that is located side by side in the horizontal direction on the diaphragm, the front of the pair of support brackets are fixed to the cover with a bracket, one side Is provided with a motor that is connected to the hydraulic piping, the vibration is made by the vibration of the motor up and down The.

In another aspect of the present invention, a plurality of through holes are formed at an angle of the diaphragm, so that the diaphragm is not twisted by the strength generated in the structure of the upper end of the cover.

As described above, the present invention is provided with a vibrating portion on the front surface of the flat work device for flattening the concrete pouring surface, the effect of placing the pouring surface removed from the residual concrete removal portion flat by the vertical vibration of the vibration plate driven by the motor have.

Hereinafter, the components will be described with reference to the drawings.

1 is an overall configuration diagram of a concrete flat work device according to the present invention, comprising a flat work device 10 and the vibration unit 20, the connecting member 30 and the residual concrete removal unit 40, the flat work The front surface of the device 10 is provided with a vibrating portion 20 for flattening the concrete pouring surface, the flat work device 10 and the vibrating portion 20 is composed of the first, second connecting members (31, 32) The connecting member 30 is connected to each other.

The first connection member 31 moves the vibrator 20 up and down to flatten the concrete placing surface, and the second connection member 32 is connected to the rear surface of the vibrator 20 to be driven by wheels. When the work device 10 moves behind the worker in the working direction, the vibrator 20 also moves in conjunction with the flat work device 10.

The vibrating unit 20 is provided with a residual concrete removing unit 40 for removing the remaining concrete debris before flattening the concrete pouring surface in the vibrating unit 20.

The vibrator 20 is described with reference to the perspective view, the front view, and the plan view of FIGS. 2 to 4, and the vibrator 20 has the end of the first connection member 31 positioned at the center thereof with the bolt B A pair of support brackets 22 are fastened with nuts N, and the connecting rods 23 are inserted at the front and rear ends of the pair of support brackets 22 in a horizontal direction.

A support rod 221 is provided inside the pair of support brackets 22, and both ends of the support rods 221 are inserted into the left and right support brackets 22 to maintain the support brackets 22 without being twisted. .

Both ends of the connecting rod 23 are provided with a guide member 242 connected to the laser measuring device 24 and the connecting member 241, and a bracket 243 is provided below the guide member 242, the cover 26 Bolt (B) is fastened to the upper surface.

The front of the pair of support brackets 22 is fixed to the upper surface of the cover 26 with a bracket 252, the motor 25 is provided with a hydraulic pipe 251 is connected to one side, driving the motor 25 By vibrating the vibration unit 20 is made up and down.

The hydraulic pipe 251 connected to one side of the motor 25 is separated into an inlet pipe 251a and an outlet pipe 251b, and a bracket 252 is provided at one side of the motor 25 in a vertical direction to cover the cover ( The motor 25 is fixed to 26.

A plurality of through holes 212 are formed in the angle 211 of the diaphragm 21, so that the diaphragm 21 is not twisted by the strength generated in the structure of the upper end of the cover 26.

Referring to the operation method of the screed flattening structure of the concrete flat work apparatus of the present invention configured as described above are as follows.

In order to flatten the concrete pour surface using the concrete flat work device of the present invention in order to flatten the floor of concrete, such as a building and a road, such as a large building or shopping mall, the flat work device of FIG. When 10) is transported toward the rear of the worker is scraped concrete remaining on the bottom surface by the residual concrete removal unit 40.
