Description
Technical field
The present invention relates to technical field of buildings, especially a kind of stairway steel formwork for building.
Background technology
At present mostly using wooden template during casting concrete, worker's formwork time is longer, and efficiency is low, constructs
Mostly there are larger insecurity in journey, and form for seal is poor and there is the risk for the mould that rises, the concrete component poured
It is of poor quality unsightly, wooden template after use has deformed more and recycling rate of waterused is low, and the number of turnover is easily stuck up more than 4 times
Song, improper use are used in turn and do not exceed 10 times, need joist, back cord facility material more and easily degumming, rise and rouse, flake, opening
It splits, when again assembled, plate stitch is difficult to handle, and thickness deviation is not easy to grasp, and leads to building structure interface dimensions deviation, cut quality
Difference will use the small rack saw piece of alloy to cut, after use will brush releasing agent, and need to handle plate face, plank sheathing through water logging of daring not accept,
It is exposed to the sun after immersion especially afraid of water, plank sheathing is easily deformed, and is uneven so as to cause concrete face.
At the construction field (site), most rambunctious is that carpenter uses plank sheathing operating process, if not strengthening the materials of plank sheathing
Management is assembled in strict accordance with the blanking of plank sheathing construction diagrams, easily causes plank sheathing waste of material, increases engineering cost.

Foot bolt is connected stair bottom plate with stair girder by stair bottom plate preformed hole.
The foundation bolt bottom is provided with bottom plate, and the bottom plate is welded on foundation bolt, is matched on the foundation bolt
There is double nut, the double nut is fixed on foundation bolt.
Lifting plate is provided on the stair beam, the lifting plate is welded on stair beam, is set on the lifting plate
Hole for hoist is equipped with, the hole for hoist is the circular hole of diameter 40mm.
Step plate is set on the perpendicular rib of marking time, and the step plate, which is welded on, marks time on perpendicular rib.
The stair girder is provided at both ends with preformed hole, and the preformed hole is the circular hole of diameter 28mm.
The step plate is 3mm panels.
Bottom plate preformed hole is respectively equipped on the noseplate and rear bottom plate, the bottom plate preformed hole is diameter 28mm circular holes.
Advantageous effect is possessed by the present invention：
The present invention it is scientific and reasonable for structure, it is safe and convenient to use, stair punching block version for building during casting concrete more
Add securely, reduce the insecurity in work progress, worker's formwork is convenient and simple, when substantially reducing worker's formwork
Between, and closure can effectively prevent well the mould that rises, template high recycling rate, environment-friendly high-efficiency may advantageously facilitate the green of unit in charge of construction
Construction.
Stairway steel formwork for building fundamentally saves timber resources and a large amount of human resources, reduces raw material
Waste, before it is completely solved the drawbacks of wooden template, installing and dismounting and height adjust flexible and convenient, labor and material saving, effectively
Improving construction quality reduces construction cost, improves work efficiency, concrete formation is high-quality, Novel beautiful, low cost, no
Using that can shorten construction period when stairway steel formwork for building, high efficiency, Er Qie are brought to unit in charge of construction for corrosion-vulnerable
When construction, it will not worry that template demoulds.
