Description

Technical Field

[0001] The utility model specifically relates to a steam curing pool for prefabricated concrete parts, and belongs to the technical field of prefabricated concrete applications. Background Art

[0002] Precast concrete parts refer to concrete parts of buildings or structures that are pre-processed and manufactured in a standardized and mechanized manner. These precast parts can be mass-produced in factories and then transported to the construction site for assembly, which greatly improves construction efficiency and saves labor costs. Precast concrete parts have a wide range of applications, including but not limited to transportation fields such as buildings, bridges, tunnels, subways, railways, and highways. In buildings, precast concrete parts can be used to build residential buildings, industrial plants, shopping malls, commercial complexes, etc. The advantages of precast components include short production cycle, stable quality, and high precision. They can improve construction efficiency, reduce labor intensity, and better meet the needs of modern buildings. Steam curing tank is a device used for curing precast concrete parts. Its working principle is to generate steam in the heated water tank and send the steam into the curing tank, so that the precast concrete parts can be cured in a standard environment with higher temperature and humidity to accelerate the hardening of concrete. Steam curing tanks are usually composed of heating systems, water circulation systems, control systems, and other parts.

[0003] The existing application is CN201310260819.7, which is a concrete precast pile steam curing pool. It includes a plurality of pool bodies (101). The top outer sides of the four side walls (103) of each pool body (101) are provided with water seal grooves (2) surrounding the pool body (101) and communicating with each other. The adjacent two side walls (103) of adjacent pool bodies (101) share a water seal groove (2). Each pool body (101) is provided with a pool cover (7). The edge of each pool cover (7) is provided with a cover edge (701) extending downward into the water seal groove (2).
