Description
Technical field
The present invention relates to prefabricated building components construction field, be specifically related to a kind of and guardrail integral prefabricated building
Air-conditioning plate terraced, prefabricated and construction method thereof.
Background technology
Face in the work progress of limit at prefabricated assembled stair, air-conditioning plate, generally require and take appropriate measures
Ensure the site safety in work progress and construction quality.
In traditional construction, generally use the method gone along with sb. to guard him, mainly have a two ways: set up scaffold and
Set up plug-in overhanging type guardrail on existing body of wall, but set up scaffold and not only need to waste substantial amounts of raw material,
Increasing the cost of construction, also can take a large amount of construction site, effect on environment is the biggest, and at scaffold
Set up during, in order to fixing scaffold, toward contact will perforate on the most prefabricated wallboard,
The globality of this meeting heavy damage body of wall and aesthetic property, affect the quality of precast wall body.And overhanging type fence exists
Though comparing setting up of traditional pin hand cradle in setting up to have simplified, but in order to guardrail is fixed, need also exist for
Perforate on existing Side fascia, causes damage to the globality of existing body of wall.Reparation construction is by workman's industry simultaneously
Business quality influence is relatively big, and mend construction in later period easily makes exterior wall surface uneven, and coating application has aberration,
Exterior wall perception is poor, and Seepage easily occurs.
Afterwards, prior art occurs in that again and a kind of uses steel tube fastener as the method facing limit guardrail, executing
First remove steel tube component scaffold when work is complete, building body structure is slotted, use expansion bolt to fix and protect
Hurdle is welded to connect sheet, welds guardrail.But use steel tube fastener loaded down with trivial details as the method operation facing limit guardrail,
Also need to remove temporary steel circumference of cannon bone to protect when installing permanent structure guardrail；In permanent structure guardrail construction Shi Xu building
Punch on ladder or air-conditioning plate, expansion bolt is installed, these meeting heavy damage stair or the globality of air-conditioning plate and U.S.
The property seen, affects prefabricated building or the quality of air-conditioning plate, and also needs repairing reserved when the fixing end construction of later stage guardrail
Locate, and mend easily occurs surface irregularity, the problem of appearance difference in construction in later period.Additionally,
The construction of other operations of work surface cross influence is easily caused when precast stair or the rendering of air-conditioning plate, reparation construction.
