Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, in particular to a concrete leveling device. Background Art

[0002] After concrete pouring and vibration, it is smoothed and subsequently finished. However, during the smoothing process, the lower layer of concrete may lack fluidity, resulting in low local concrete strength. Sometimes, while meeting construction requirements, water is added at the construction site to increase the fluidity of the concrete. However, this can cause segregation in the concrete, changing its properties and water-binder ratio, resulting in a decrease in strength. Utility Model Content

[0003] The utility model aims to provide a concrete leveling device which can improve the fluidity of concrete during the leveling process and make it fully dense.

[0004] The utility model is realized by the following measures: a concrete troweling device, characterized in that it comprises a trowel plate, a row of columns arranged at one end below the trowel plate, and a handle arranged at one end above the trowel plate;

[0005] The handle is located on the outside of a row of columns.

[0006] Furthermore, the upper end of the column is connected to the trowel plate through threads.

[0007] Furthermore, a sleeve 1 is fixedly provided on the upper end surface of the trowel plate and corresponds one to one with the column, the column is slidably provided in the sleeve 1, the lower end of the column extends out of the trowel plate, and a screw 1 is concentrically fixed on the upper end, the outer diameter of the screw 1 is smaller than the outer diameter of the column, and the upper end of the sleeve 1 is provided with a threaded hole that cooperates with the screw 1.

[0008] How to use:

[0009] After concrete pouring and vibration, the surface is uneven and needs to be smoothed before finishing. This tool is used for concrete smoothing. The construction worker holds the handle and moves backwards, so that the column contacts the concrete first, improving the fluidity of the concrete and making it fully dense, avoiding the phenomenon of insufficient local concrete strength. The concrete is then smoothed with the trowel.

[0010] The column is threadedly connected to the trowel plate, and its exposed length can be adjusted by rotating the column, and the column can also be disassembled and reassembled. This embodiment does not use electricity, saves electricity, and has no fire hazard.

[0011] Furthermore, a row of vibrating rods is provided on the trowel plate and between the row of columns and the handles;

[0012] The trowel plate is provided with a sleeve 2 corresponding to the vibrating rod one by one, the vibrating rod is slidably arranged in the sleeve 2 and a screw 2 is fixedly arranged on the upper end, the upper end of the screw 2 extends out of the sleeve 2 and a nut is provided on the extended end;

[0013] A vertical plate is fixedly provided on the trowel plate and located between the second sleeve and the handle, a motor shaft and a cam shaft are rotatably provided on the vertical plate, and the motor shaft and the cam shaft are connected via a transmission mechanism;

[0014] The upper ends of all screw rods are fixed on the adjustment plate, and the cam on the camshaft is located below the adjustment plate and contacts the lower end surface of the adjustment plate;

[0015] A motor driving the motor shaft to rotate is fixed on the vertical plate or the handle;

[0016] The cam rotates and the vibrating rod moves up and down.

[0020] Furthermore, the vibrating rod and the column are staggered with each other.

[0021] Usage: When using the vibrator, the motor is started, which drives the motor shaft to rotate. The motor shaft, through a transmission mechanism, drives the camshaft to rotate. The cam on the camshaft rotates accordingly. During the rotation of the cam, the outer wall of the cam contacts the lower end surface of the adjustment plate. During this contact process, the vibrator continuously moves up and down, thereby vibrating the concrete. This embodiment uses a motor to improve the concrete vibration effect. When the column meets the construction requirements, the motor and vibrator can be removed.
