Description

Technical field:

[0001] The utility model relates to the technical field of concrete moulds, in particular to a demoulding device for RPC concrete prefabricated parts. Background technology:

[0002] RPC is the abbreviation of reactive powder concrete, which is a newly developed new type of concrete with ultra-high strength, high toughness and extremely low permeability. It overcomes the low flexural tensile strength of high-strength concrete (HSC), the difficulty of construction pouring due to reinforcement reinforcement, and the cracking of concrete. It is a new type of concrete with ultra-high mechanical properties and durability prepared according to the principle of minimum defects, and has broad application prospects. However, due to its powdery nature, it takes a lot of time to mix it on site when it is used. Therefore, in order to save construction time, it is often prefabricated into standard blocks.

[0003] RPC concrete prefabricated blocks require the use of molds. After the RPC concrete prefabricated parts are dried, the prefabricated blocks need to be separated from the molds. Currently, most molds have openings on one side. In order to facilitate demoulding, they are demoulded by impact, knocking or vibration. However, since it is difficult to control the strength of mechanical impact and knocking, the RPC concrete prefabricated parts are easily damaged, resulting in a problem of reduced yield.
