Description

Technical Field

[0001] The utility model relates to the technical field of building construction equipment, in particular to a detachable concrete spraying and curing device. Background Art

[0002] After the concrete has finally set, it needs to be cured to ensure that the concrete surface is moist, thereby ensuring that the cement hardens smoothly and that the newly poured concrete can harden normally or accelerate its hardening and strength growth. If the curing is not carried out in time, when the concrete surface loses water, the cement hydration reaction stops, and its surface will dry and shrink, eventually forming cracks, affecting the structural safety and normal use.

[0003] Concrete walls are generally high and need to be cured after the concrete walls are demolded; the traditional cast-in-place concrete curing relies on workers to water and maintain, which is time-consuming and labor-intensive. In summer and high-temperature weather, water evaporates quickly, and the concrete surface needs to be watered and maintained every 1 to 2 hours. It is difficult to arrange manual curing, which can easily lead to untimely curing. Concrete walls are generally high, and manual curing can easily lead to uneven watering of the high concrete surface, and uneven watering in various places, resulting in inadequate curing of concrete in some locations, leading to concrete cracking.

A T-shaped card insert 45 is fixedly connected to the wing plate 42, and a card slot 46 matching the card insert 45 is provided on the outer support rod 21 and the inner support rod 22.

[0024] The slot 46 does not penetrate the outer support rod 21 and the inner support rod 22 in the transverse direction. The outer support rod 21 and the inner support rod 22 are each provided in two groups, and the outer support rod 21 and the inner support rod 22 are symmetrically arranged, so that the opening directions of the slot 46 on the two groups of outer support rods 21 and inner support rods 22 are opposite; when the insert 45 is inserted into the slot 46, the staff puts the water spray pipe between the symmetrically arranged arc rods 41, and the staff uses the fastening bolts 44 to pass through the connecting plate 43, so that the arc rod 41 clamps the water spray pipe. Since the opening directions of the slot 46 on the two groups of outer support rods 21 and inner support rods 22 are opposite, the water spray pipe is restricted in the transverse direction, and the insert 45 cannot easily slide out of the slot 46.

[0025] In order to improve the spraying efficiency and spraying area, multiple groups of clamp assemblies are provided, and multiple groups of water spray pipes 1 are also provided. When two water spray pipes 1 are used, four groups of clamp assemblies are symmetrically inserted into the inner support rod 22 or the outer support rod 21, and the end of the water delivery pipe 5 is fixed on the three-way connecting pipe, and then the three-way connecting pipe is connected to the water pump.
