One-time continuous pouring forming structure and construction method of integral aluminum formwork staircase

Abstract

The invention relates to a one-step continuous pouring molding structure for stairs by adopting an integral aluminum template. The structure mainly comprises a template supporting bracket, steel tubes, limit members, clamping grooves, embedded parts, a bottom plate, transverse stiffening ribs, a serrate side surface plate and L-shaped step plates, wherein the steel tubes penetrate reserved holes, and the template supporting bracket is put on the steel tubes; two ends of the template supporting bracket are fixed on a floor beam and a middle platform beam through the embedded parts respectively; the transverse stiffening ribs are evenly arranged on the back surface of the bottom plate, the bottom plate is arranged on the template supporting bracket, and the transverse stiffening ribs are placed in the clamping grooves; the L-shaped step plates are arranged on the serrate side surface plate and are connected, fixed and molded through bolts. By means of the structure, the construction site order and the construction efficiency are improved, steel tube support structures are not required to be constructed from top to bottom, the concrete pouring quality is guaranteed through relevant measures, workers can pass up and down in a construction process, construction of the stairs is facilitated, and better technical and economic benefit is realized.

Description

technical field [0001] The invention relates to a method for stair pouring construction using an integral shaped aluminum formwork template in a building standard floor, belongs to the field of building construction engineering, and is suitable for stair pouring construction of 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 integral type, and wooden formwork, shaped aluminum formwork and 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 consumption, and inconvenience for masters in the integral pouring construction of building stairs. First hoist and temporarily place it on the steel pipe, fix the two ends of the support frame on the floor beam and the middle platform beam through the embedded parts, set a slot on the top of the support frame, fix the stiffener part of the prepared bottom plate in the slot, and place the The assembled tread panels and side panels are hoisted and docked with the bottom plate, and then the concrete is poured as a whole and is vibrated synchronously with the vibrator for compaction
