Description
Technical field
Stair pouring construction is carried out using monoblock type sizing aluminum alloy pattern plate template in architecture Standards the present invention relates to one kind
Method, belong to building engineering field, suitable for the more business of index bed live build etc. stair pouring construction.
Background technology
Stair in building construction are as important feature current up and down, while important escape when also occurring as earthquake
Passage, the selection of stair construction method take into account economy while must assure that the security reliability of stair.Stair are adopted more at present
Constructed with cast-in-place monoblock type, generally use plank sheathing and sizing aluminum alloy pattern plate and steel form in work progress.
Plank sheathing convenient material drawing, scene processing adapt to the staristep of various sizes, but the reinforcement by connection between plank is usual
Reinforced using iron nail, and stair template is in vacant state before cast-in-place concrete, lateral pressure is big during concreting, adds
Operating personnel trample in upper work progress, cause to run mould, shifting phenomena often occurs, and influence stair Surface Quality of Concrete.
In addition, the scene processing of plank sheathing needs several carpenter's cooperatings, narrow field, the difficulty of construction management is increased, and
The plank sheathing number of turnover is few, costly.And shape aluminum alloy pattern plate and steel form global formation, can be with Reusability, cast-in-situ stair section
Size is accurate, but input cost is big, and bottom need to set steel pipe support, need to treat concrete reach strength of mould stripping can form removal, steel
Mould turnover rate is low, and steel form is heavier is inconvenient to lift.
These problems run into for architectural stair in Practical Project, it is necessary to it is high, economic to develop a kind of efficiency of construction
Property good stair construction method, exactly exploitation forms the present invention in this context, in being constructed applied to actual stair must
Preferable economic and social benefits will be produced.
The content of the invention
It is an object of the invention to for quantities is big, time-consuming, upper people present in the construction of architectural stair one-piece casting
The problems such as inconvenient, it is proposed that a kind of stair construction method of monoblock type typified form continuously poured in one shaping, this method is by mould
Plate bracing frame is first lifted and is temporarily placed on steel pipe, and support frame both ends are fixed on into floor beam and halfpace beam by built-in fitting
On, neck is set at the top of support frame, the flank of putting more energy into for making bottom plate is fixed in neck, by stepping on for pre-assembly shaping
Panel and side panel lifting is docked with bottom plate, then one-piece casting concrete and coordinate vibrator synchronous vibration densification.
In order to realize above-mentioned technical purpose, present invention employs following technical scheme：
A kind of monoblock type aluminum alloy pattern plate stair continuously poured in one molding structure, it is characterised in that：The structure mainly includes：
