An object of the utility model is to provide a seal stair construction and use a formwork to solve the problem that proposes in the above-mentioned background art.
In order to solve the technical problem, the utility model provides a following technical scheme:
the utility model provides a closed stair construction is with a formwork, includes pole setting, horizontal pole, wood purlin, plywood, to drawing screw rod, steel pipe, sweeps floor pole and pre-buried reinforcing bar head, is located to be equipped with stair between the platform of upper and lower both sides, and the stair surface mounting who is located the downside has the pole setting, there is the horizontal pole through bolt fixed mounting in the pole setting, installs the top of sweeping floor the pole setting between horizontal pole and the pole setting and is equipped with wood purlin, and the bottom of wood purlin is equipped with to drawing the screw rod, and the upper portion of wood purlin is equipped with the plywood, and the intersection of stair is equipped with pre-buried reinforcing bar head, and the upper portion of stair still is equipped with the steel pipe.
As an optimal technical solution of the utility model: the upright posts are provided with 3-4 groups of round steel pipes, and the distance between the upright posts is less than 1200 mm.
As an optimal technical solution of the utility model: the cross rod and the vertical rod are the same in specification and size.
As an optimal technical solution of the utility model: the length and width specification of the wood purlin is 50 x 100cm and the thickness is 250 mm.
As an optimal technical solution of the utility model: the steel pipe is provided with two sets and adds the butterfly buckle through drawing the screw rod to consolidate, draws the screw rod transversely, vertical interval all is not more than 500mm to drawing.
The utility model discloses the beneficial effect who reaches is: this formwork is consolidated through adding the butterfly buckle to the split screw, and horizontal, the longitudinal separation of split screw is all not greater than 500mm, and the tread of stair, the surface of playing all adopt the template to seal the assembly, consolidates at the reentrant corner department back of tread and surface of playing flitch, and the external corner department of tread and surface of playing adopts 5 angle steel to consolidate the angle bead, has solved easy bloated mould, the shaping size deviation is great, the impression is relatively poor scheduling problem through above-mentioned formwork.
