Spray maintenance telescopic spray head

Abstract

The invention provides a spray maintenance telescopic spray head. The spray maintenance telescopic spray head comprises a connecting pipe, the connecting pipe is connected with a water supply pipe, asliding body is slidably connected in the connecting pipe, under the action of water pressure, the sliding body partially extends out of the connecting pipe, under the action of no water pressure, thesliding body retracts in the connecting pipe, a water channel is arranged in the sliding body, a spray head device is rotatably connected to the tail end of the sliding body, the spray head device communicates with the water channel, and the spray head device swings left and right under the action of water pressure by taking a central shaft of the sliding body as a rotating shaft. According to the spray maintenance telescopic spray head, the technical effects that the site occupancy rate is greatly reduced, the construction difficulty and the construction cost are greatly reduced due to sitesaving, the telescopic swing spray head has no interference with formwork erecting and detaching of cast-in-place components, formwork erecting and detaching are conveniently and rapidly carried out,the construction efficiency is improved, the economic benefit is obvious, the spray area of the spray head is increased through the swing spray head, the spraying effect is better, the curing effect is improved, the strength of the components is guaranteed, and water resources are saved are achieved.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a telescopic nozzle for spray maintenance. Background technique [0002] Concrete has become one of the most important materials in modern construction, and the performance of concrete after pouring is largely dependent on the later maintenance. During the maintenance, the surface of the concrete is usually wet to ensure the hydration performance of the cement Otherwise, the concrete is prone to cracks, which will affect the strength of the concrete structure. [0003] In the prior art, more and more automatic spraying is used to spray and maintain cast-in-place building components. In the process of cast-in-place building components, because it involves the need to erect formwork and remove formwork at the construction site, conventional erection in cast-in-place The sprinklers around the components are easy to interfere with the construction, reduce the constr...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the present invention provides a sprinkler maintenance retractable nozzle, which solves the problem that conventional sprinkler nozzles erected around cast-in-place components in the prior art can easily interfere with construction and reduce construction efficiency , the site occupies a large area, and the dense installation of sprinkler nozzles increases the difficulty of erecting and dismantling the formwork. The sparse installation of sprinkler nozzles results in poor spraying effect, which reduces the maintenance effect and affects the structural strength of cast-in-place components.
