Steel stair formwork and constructing method for once pouring forming of building staircase

Abstract

The invention discloses a steel stair formwork for once pouring forming of a building staircase and belongs to the field of building construction. The steel stair formwork comprises two inclined beams and a plurality of step side moulds, wherein the two inclined beams can be erected between an upper-layer stair landing and a lower-layer stair landing which are adjacent to each other. The two inclined beams can be arranged in parallel at interval, the two corresponding ends of the two inclined beams are fixedly connected through horizontal beams to form a formwork body, and height adjusting devices are arranged at the two ends of the formwork body. The step side moulds are sequentially fixed under the formwork body at intervals from top to bottom, the length of one step side mould is larger than the width of the formwork body, the same sides of the step side moulds are fully sealed through steel plates, and winged edges perpendicular to the steel plates are arranged at the tops of the steel plates. The steel stair formwork is convenient to install, simple to construct, easy to operate, capable of achieving simultaneous pouring of stairs and wall bodies of the staircase, capable of avoiding secondary embedded reinforcing steel bars, capable of guaranteeing the integrity of the staircase and capable of achieving tooled and standardized operation of staircase structure construction. The invention further discloses a constructing method for once pouring forming of the building staircase.

Description

technical field [0001] The invention relates to a steel stair formwork for building stairwells and a construction method, in particular to a steel stairway formwork and construction method for building stairwells formed by one-time pouring, and belongs to the field of building construction. Background technique [0002] In recent years, the country has vigorously promoted the industrialization of construction, relying on scientific and technological progress and technological innovation to improve the level of industrialization of construction, and ultimately achieve energy conservation, emission reduction, green construction, and sustainable development of the construction industry. [0003] In construction engineering, as the main construction channel, stairs are the main channel for buildings to deal with accidents such as power outages and fires, and for inspections by all parties. Therefore, the quality of stairwell construction plays a key role in building safety. In t...

AI Technical Summary

Problems solved by technology

In the traditional building construction process, the stairwell and the main body are usually constructed separately, and secondary reinforcement is required, which increases the construction complexity and construction cost, and reduces the construction efficiency; at the same time, it affects the flatness of the stairwell wall. Weaken the integrity of the stairwell

In addition, the strength of the stair wooden step formwork used in the prior art is low, and the phenomenon of "exploding mold" is prone to occur during the construction process; the wooden step formwork cannot be reused, resulting in waste of timber resources and affecting construction efficiency
