Problems solved by technology

The disadvantage of these two methods is that in addition to the heat carried by the steam upwards to the mold table, most of the heat is transmitted downward to the ground or to the air along the surroundings, resulting in a large amount of waste of heat and resulting in a faster temperature rise of the hot mold table. Slow and long maintenance cycle, increasing energy consumption and production costs, reducing production efficiency
Compared with the wet heat curing process, although the dry heat curing process has the advantages of less damage, short curing period, better surface of the product, and low energy consumption, the dry heat curing process is mainly based on the evaporation of water in the concrete, and there are concrete failures. More water, unreasonable cement hydration conditions, greater loss of strength in the later stage, etc.

Abstract

The invention discloses an efficient PC component hot mold platform integrating dry and wet heat curing. The hot mold platform comprises a concrete bottom frame, a mold platform for installing and fixing a PC component mold, and a sliding telescopic type steam curing cover; heat preserving plates are attached to the periphery of the inner side of the concrete bottom frame which comprises two sunken holes; positioning FRP ribs are arranged at the bottoms of the sunken holes; colored steel plates are arranged on the tops of the FRP ribs; meshes are laid on the colored steel plates; by means of casting of foam concrete, the colored steel plates, the meshes and the foam concrete are connected into a whole to form a heat insulating concrete layer; the mold platform is installed on the concrete bottom frame through welding between the mold platform and an embedded part; a heat preserving layer with a cavity is formed between a panel and each sunken hole; and the sliding telescopic type steam curing cover comprises a supporting framework and heat preserving tarpaulin. The efficient PC component hot mold platform integrating dry and wet heat curing can perform full-dry heat curing, full-wet heat curing and dry-wet heat curing on PC components and has the beneficial effects of being high in temperature rise speed, good in heat accumulation, small in energy consumption and high in production efficiency and space utilizing rate.

Description

technical field [0001] The invention belongs to the production field of PC (prefabricated concrete structure) components, and in particular relates to a high-efficiency thermal mold table for PC components integrating dry, wet and heat curing. Background technique [0002] Since the 21st century, with the continuous development of the construction industry, the disadvantages of the concrete cast-in-place structural system have become increasingly prominent, and green buildings have gradually become the development trend of my country's construction industry. Under the vigorous promotion of the Chinese government, "construction industrialization", "housing industry At the same time, the demand for PC (Prefabricated Concrete Structure), that is, "prefabricated concrete structure" components, has greatly increased. PC components are finished concrete components made in component processing factories. In the production process of PC components, the maintenance process is one of ...
