Description
Technical field
The present invention relates to floor slab construction field, particularly relates to a kind of cast-in-situ stair closing formwork erecting structure and its flow backward concrete
Construction.
Background technique
In cast-in-situ stair work progress, usually bench is marked time and is separated with template, top surface hollow out of marking time, concrete is from hollow out
Face is poured, and work progress has the following problems:
The concreting of stair bench cannot be carried out continuously, time-consuming work consuming.Since stair step absolute altitude is different, concrete is poured
Build it is appropriate to the occasion carried out from bench lower to upper part, when pouring top concrete, if concrete flowability is big, lower part concrete can be by
It is acted on to top concrete gravity power and overflows template, therefore bench need to be poured close to secondary when initial set when concrete；
Concrete final set front stairs can not be used as vertical transport channel.Before bench concrete final set, stepped on if people steps down in
It walks in step, easily leaves footprints on marking time, influence concrete impression quality.
Vulnerable to damage after bench molding, finished product protection need to be carried out.Since stair are people, material passway, traffic volume is big, ladder
Duan Chengpin is highly prone to destroy, and needs to be surrounded with template during routine use and mark time, carries out finished product protection to it.
Summary of the invention
The present invention to solve problems of the prior art, proposes that a kind of cast-in-situ stair closes formwork erecting structure and its reverse irrigation
The construction of concrete.
The technical scheme of the present invention is realized as follows:
