Abstract
Description
technical field
[0001] The invention relates to the field of concrete staircase prefabricated parts, in particular to a concrete staircase production mold, a concrete staircase production method, and a concrete staircase. Background technique
[0002] Using prefabricated structural parts to build buildings is beneficial to increase the speed of construction. In some areas with low ambient temperature, concrete is not easy to solidify, and the use of prefabricated structural parts to build buildings is also conducive to reducing construction difficulty and construction costs. Moreover, mass production of concrete prefabricated parts in factories helps to reduce production costs and environmental pollution.
[0003] The background technology part of the patent document CN110821062A records that the concrete stairs manufactured by the traditional prefabricated staircase production process, because the surface of the stairs is too smooth, it is difficult to perform the operatio...
