Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a concrete curing device for building construction. Background Technology

[0002] Concrete curing involves artificially creating certain humidity and temperature conditions to allow freshly poured concrete to harden and increase its strength normally or at an accelerated pace. The reason why concrete can gradually harden and increase its strength is the result of cement hydration. Cement hydration requires certain temperature and humidity conditions. Currently, most methods to increase the humidity of concrete are to spray water onto the concrete surface using concrete curing devices.

[0003] Existing concrete curing methods mostly involve construction workers manually spraying water onto the concrete surface using hoses. This not only increases the physical labor of construction workers but also results in long curing times and low efficiency. Furthermore, existing concrete curing devices use fixed spray mechanisms with a single spray direction and a small spray area, making it inconvenient for efficient curing of concrete during construction. Therefore, we offer a concrete curing device for construction projects that solves these problems. Utility Model Content

[0014] (iii) Beneficial effects:

[0016] I. This utility model uses an external moving mechanism to mount a guide rod above the concrete, and an external water supply mechanism to deliver water to the nozzles through a water pipe. The nozzles humidify the concrete. A drive motor drives a drive wheel to rotate via a toothed belt, which in turn drives a reciprocating screw to rotate.

The power wheel drives a fixed wheel to rotate, which in turn drives a power shaft to rotate. The power shaft, via transmission chain A, drives the fixed wheels on both sides of the support frame to rotate simultaneously. Under the action of a fixed spring, the slider keeps the contact wheel pressed against the guide rod. The fixed wheel moves along the guide rod under the limit of the contact wheel, thereby realizing automatic humidification of the concrete. This solves the problem that existing concrete curing methods often require construction workers to manually spray water onto the concrete surface, which increases the physical labor of construction workers and results in a long curing time. It has the advantage of automatic humidification. Attached Figure Description
