The invention relates to the technical field of concrete equipment, and discloses a concrete trowelling device for building construction, which comprises a trowelling blade, the middle part of the trowelling blade is mounted at the bottom of a rotating shaft through a connecting structure, and the top of the rotating shaft is mounted at the output end of a power device. The casing pipe is arranged outside the rotating shaft, the casing pipe is used for driving the fan blades to rotate, the fan blades rotate to gather airflow in the air cavity, then the heating ring is used for heating the airflow, the airflow is expanded to form high-pressure air, and in order to increase the cutting speed, water vapor is added into the airflow, so that the cutting efficiency is improved. The heating ring used for heating the air can also heat the water, so that the air used for trowelling not only contains air but also contains a certain content of water vapor, and the air flow is utilized to form an air knife to treat dry and hard concrete needing to be troweled in advance, so that the pressure of the trowelling blade is relieved, the damage of the blade is reduced, and the replacement of the blade is reduced.
Description
technical field [0001] The invention relates to the technical field of concrete equipment, in particular to a concrete troweling device for building construction. Background technique [0002] Concrete troweling machine is a device used for concrete troweling. The concrete that has been paved but not completely solidified is smoothed by the rotating blade through the troweling blade. The common structure of this troweling machine is by troweling The blade, motor and handle are combined. There are four smoothing blades, which are arranged in a cross shape through the connection structure, and then installed on the motor through the central shaft. The motor can drive the blade to rotate. When the blade rotates, it will be higher than the plane. concrete paving. [0003] In the process of smoothing concrete, due to the large construction area, some areas will have dry concrete. Although the dried concrete can also be smoothed, the strength of the trowel will increase due to th...
