Concrete trowelling device for building construction
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.
本发明涉及混凝土设备技术领域，且公开了一种用于建筑施工的混凝土抹平装置，包括抹平刀片，所述抹平刀片的中部通过连接结构安装在转轴的底部，所述转轴的顶部安装在动力装置的输出端。本发明通过在转轴的外面设置套管，利用套管带动扇叶转动，扇叶转动会将气流聚集在气腔中，然后利用加热环对气流进行加热处理，使得气流膨胀，形成高压气体，为了增加切割速度，在气流中添加水蒸气，用于加热空气的加热环也能够对水进行加热，使得用于抹平的气体中，不仅仅含有空气还有含有一定含量的水蒸气，利用该气流形成气刀，提前对需要抹平的干结混凝土进行处理，以此来减轻抹平刀片的压力，降低刀片的损坏，减少更换。
