One-time continuous pouring and forming construction method of stairs based on integral shaped formwork

Abstract

The invention relates to a staircase one-step continuous casting forming construction method based on an integral shaped formwork. The construction method mainly comprises the steps of hanging a formwork support structure, installing side surface plates and a bottom plate of the staircase formwork, binding a staircase distribution steel bar net, installing L-shaped pedal surface plates, casting concrete, dismounting the staircase formwork and the like. The formwork support structure is supported on floor beams arranged at the upper end and the lower end and a middle platform beam; the side surface plates and the bottom plate are hung on the formwork support structure through screw bolts; the L-shaped pedal surface plates are arranged in saw teeth of the side surface plates; the integral concrete casting is performed; the synchronous vibration compaction is performed through a bottom plate facing vibrator; and the corresponding shock absorption structure measures are taken. The staircase one-step continuous casting forming construction method has the advantages that the order in the construction site and the construction efficiency are improved; the concrete casting quality is ensured by relevant measures; in the construction process, personnel can go up and down; the staircase construction is convenient; and good technical and economic benefits are realized.

Description

technical field [0001] The invention belongs to the field of building construction engineering, and in particular relates to a one-time continuous pouring and forming construction method for stairs based on an integral shaped template, which is suitable for the construction of stairs in commercial and residential buildings with many standard floors. Background technique [0002] Stairs in building construction are an important structure for up and down traffic, and also serve as an important escape route when an earthquake occurs. The choice of staircase construction method must ensure the safety and reliability of the staircase while taking into account the economy. At present, most of the stairs are constructed by cast-in-place monolithic construction, and wooden formwork and shaped steel formwork are usually used in the construction process. [0003] The wooden formwork is easy to obtain, and can be processed on site to adapt to stair sections of various sizes. However, i...

Problems solved by technology

[0005] The object of the present invention is to propose a construction method for stairs with an integral shaped formwork that is continuously poured into shape at one time, aiming at the problems of large amount of work, long time-consuming, and inconvenience for people to go up and down in the integral pouring construction of building stairs. Supported on the floor beams at the upper and lower ends and the middle platform beams, the side panels and the bottom panels are suspended on them by bolts, the L-shaped tread panels are placed in the serrations of the side panels, the concrete is poured as a whole and is vibrated synchronously and densely by the bottom panel veneer vibrator, and set Corresponding shock-absorbing structural measures
