Abstract
Description
[0001] The present invention relates to the field of concrete maintenance, in particular a concrete maintenance device for construction site work.
[0002] Concrete maintenance is an essential part of concrete construction. Its main goal is to ensure, through deliberately created humidity and temperature conditions, that freshly poured concrete can undergo its curing process normally or accelerated, thereby increasing the concrete's strength.
[0003] When maintaining concrete, the degree of curing must be taken into account. It is important to avoid damaging the concrete with high water pressure from spraying water if the curing process is still insufficient. Furthermore, when watering for maintenance, it is essential to remember that the area and reach that can be covered with water are limited.
[0004] Therefore, a concrete maintenance device for construction site work is proposed that addresses the problems mentioned above.

[0010] Preferably, a limiting ring is fixed to the side of the adjustment column and is slidably connected to the hose; this arrangement ensures that the hose moves inside the limiting ring when the distributor pipe drives the hose; the limiting ring allows the hose to be held in a defined position to prevent the hose from becoming tangled and thus ensure the water flow.
[0011] Preferably, a reinforcing plate is fixedly attached to the top of the turntable, the inside of the reinforcing plate being rigidly connected to the adjustment column, and the underside of the reinforcing plate being slidably connected to the movement seat; this arrangement ensures that the rotational movement of the turntable and the adjustment column drives the reinforcing plate, and the sliding connection of the underside of the reinforcing plate to the movement seat supports the side of the adjustment column, thus increasing the stability of the adjustment column during rotation.
