Description
Technical field
The present invention relates to prefabricated building components construction field, and in particular to it is a kind of with the precast stair of guardrail integral and its
Construction method.
Background technology
Face in prefabricated assembled stair, air-conditioning plate in the work progress of side, generally require to take appropriate measures to ensure to apply
Site safety and construction quality during work.
In traditional construction, method that generally use is gone along with sb. to guard him mainly has two ways：Set up scaffold and in existing wall
On set up plug-in overhanging type guardrail, but setting up scaffold not only needs to waste substantial amounts of raw material, increases the cost of construction, also
It can take a large amount of construction sites, effect on environment is also very big, and during the setting up of scaffold, in order to fixed feet hand
Frame, toward contact will the perforate on prefabricated wallboard, this can heavy damage wall globality and aesthetics, influence prefabricated
The quality of wall.And though overhanging type fence is simplified compared to setting up for traditional scaffold in setting up, in order to add to guardrail
With fixation, the perforate on existing Side fascia is also needed, is caused damage to the globality of existing wall.Reparation construction is by work at the same time
People's professional qualities have a great influence, and mend construction in later period easily makes exterior wall surface uneven, and coating application has aberration, and exterior wall is seen
Sense is poor, and Seepage easily occurs.
Afterwards, occur a kind of using steel tube fastener as the method for facing side guardrail again in the prior art, finished in construction
Shi Shouxian removes steel tube component scaffold, slots in building body structure, piece is welded to connect using expansion bolt nonfloating rail, welds
Guardrail.But using steel tube fastener as the method tedious process for facing side guardrail, also need to remove when installing permanent structure guardrail
Interim steel pipe is gone along with sb. to guard him；It need to be punched when permanent structure guardrail is constructed on stair or air-conditioning plate, expansion bolt is installed, this can be serious
The globality and aesthetics of stair or air-conditioning plate are destroyed, influences the quality of prefabricated building or air-conditioning plate, and in later stage guardrail fixing end
Also need to repair reserved place during construction, and easily there is surface irregularity in construction in later period in mend, appearance difference is asked
Topic.In addition, it be easy to cause the construction of working face cross influence other processes in precast stair or the rendering of air-conditioning plate, reparation construction.
The content of the invention
The present invention is to solve the above-mentioned problems, it is proposed that one kind lifting is convenient, safe, reduces working procedure, saves
The precast stair and its construction method with guardrail integral of construction cost.
