In floor construction, electric trowel is a very common mechanical equipment. It can make the concrete floor more flat, smooth and solid, greatly improving the construction efficiency and floor quality. However, although the trowel is good, it cannot be sloppy when used. If it is not operated properly, it will not only affect the construction effect, but also may bring safety hazards. Next, let's talk about some key matters that need to be paid attention to when using the electric trowel.
1. The state of concrete must be judged accurately
The electric trowel is not available at any time. It has certain requirements for the dryness and wetness of the concrete. The time to start troweling is usually when the concrete has been initially set, the surface is no longer emitting water, but shallow footprints can still be left. If used too early, the concrete is easily damaged; if used too late, the machine cannot press out the effect.
2. Check the equipment status can not be saved
Before use, carefully check whether the power supply, cable, switch, transmission part and trowel of the trowel are normal. In particular, the power wiring should be standardized to prevent leakage. It is also necessary to confirm whether the spatula is worn or loose to avoid abnormalities or damage to the equipment during operation.
3. Wear protective equipment correctly
When operating the trowel, it is recommended to wear non-slip shoes, safety helmets and gloves. The ground at the work site is slippery, and the machine itself also has certain vibrations and rotational forces. Wearing appropriate protective equipment can effectively ensure personal safety.
4. The operation should be smooth
When troweling, the operator should hold the handrails firmly with both hands and keep the center of gravity stable. The movement of pushing the machine should be even and slow, and it is forbidden to push and pull violently. When adjusting the angle of the spatula, the machine should also be turned off or in a safe state to avoid rotating parts from hurting people.
5. Avoid grinding at the same position for a long time
When troweling, keep moving to prevent the machine from grinding at one point for a long time, causing local over-polishing or scratching the concrete surface. Cross-operation and repeated coverage should be achieved to ensure that the overall effect is uniform and flat.
6. Pay attention to ventilation and environmental safety
When constructing in closed places, ensure good ventilation. Electric trowels will generate a certain amount of heat and dust. If the air is not circulated, it may affect the health of the operator. In addition, the working area should be cleaned to prevent debris from getting stuck in the machine.
7. Cleaning and maintenance after use
After the construction is completed, the concrete residue on the trowel should be cleaned in time, especially the trowel and chassis. Regularly checking the lubrication parts, bolt tightening conditions, etc. will help extend the service life of the machine and ensure the smooth progress of the next construction.
Although the electric trowel is an important tool to improve construction efficiency, it must be used at the right time and in the right way. Mastering the basic operating specifications and precautions can not only improve the construction quality, but also reduce equipment loss and safety risks. For every construction worker, careful operation and careful maintenance can make this "ground beautician" play the greatest value.
