Adjustable type universal stair formwork

Abstract

The invention discloses an adjustable type universal stair formwork. The adjustable type universal stair formwork comprises step surface formworks (3), step kickplate formworks (4) and a side edge formwork (1). A length adjusting structure is arranged on each step surface formwork (3). A height adjusting structure is arranged on each step kickplate formwork (4). A telescopic adjusting structure is arranged on the side edge formwork (1). A stair angle adjusting structure (7) is arranged at the bottom of the connection portion between the stair and a lower platform (6). A kickplate angle adjusting device (8) is arranged at the bottom of each step kickplate formwork (4). Each kickplate angle adjusting device (8) enables the corresponding step kickplate formwork (4) to be connected with the adjacent step surface formwork (3). By the adoption of the adjustable type universal stair formwork, the length, the height and the angle of the stair formwork can be adjusted, the universality is high, recycling can be achieved, the problems that steel and wood of an existing stair formwork are used disorderly, and efficiency is low can be solved, the progress of industrialization and standardization of constructional engineering is accelerated, and energy consumption and construction cost are reduced.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to an adjustable universal staircase formwork. Background technique [0002] After years of development in concrete structure construction, a variety of formwork systems have been formed, but most of the formwork for stairs is still in the original wood state. Although there are some areas and projects that use shaped steel forms, the shaped steel forms can only be used for a single project. Once the engineering structure is completed, the special shaped steel formwork will become scrap iron, resulting in the waste of steel during construction and increasing the construction cost. Hidden danger to quality. [0003] In order to realize the repeated turnover of stair formwork, many technical personnel in the art have carried out a large amount of exploration and innovation, as disclosed in the open data of CN202831629U of Chinese patent literature authorizat...

Problems solved by technology

[0004] The purpose of the present invention is to provide a universal stair formwork with high construction efficiency, which can replace scattered wood, enable stair and structure to be integrated, and the key point is to allow multiple projects to be reused, so as to solve the confusion and inefficiency of the use of steel and wood in the current stair formwork to promote the process of industrialization and standardization of construction engineering, while reducing energy consumption and construction costs
