Abstract
The invention discloses a light and thin beam type prefabricated staircase of ultra-high performance concrete and its forming process. The prefabricated staircase includes steps, platforms and inclined beams. The prefabricated staircase is made of ultra-high performance concrete. The steps can be freely combined, and the selected steps are connected to the steps and the platform through the cast-in-place inclined beams. The invention has a simple structure, and puts forward a design scheme in which the steps can be assembled, which solves the problem of inflexible adjustment of the traditional prefabricated staircase mold; it utilizes the ultra-high strength, ultra-high toughness, and ultra-high durability of ultra-high performance concrete to meet the requirements of the staircase. Under the premise of bearing capacity and normal use conditions, the section size of the stair parts is reduced to reduce the dead weight and cost.
Description
technical field [0001] The invention relates to the technical field of building construction, in particular to a light and thin beam-type prefabricated staircase of ultra-high performance concrete and a molding process thereof. Background technique [0002] Construction industrialization is an important way to improve labor efficiency and construction quality, and it is also the development direction of my country's future construction industry. As one of the representatives of construction industrialization, the state and local governments have issued a series of policies to promote its high-quality and rapid development. A large number of building parts of prefabricated buildings are produced and processed in workshops, which can improve production efficiency and save energy and protect the environment. [0003] Prefabricated stairs are widely used in prefabricated buildings in the context of building industrialization. At present, the reinforced concrete stairs built in...
