Description
Technical Field
The utility model belongs to the construction field, concretely relates to strength nature shaped steel concrete roof beam hangs operation platform down.
Background
A steel pipe fastener type scaffold is adopted to set up a formwork support as a concrete formwork support and operation platform in a traditional concrete pouring method, the method is simple to set up and low in cost, but formwork expansion is easy to occur in concrete pouring due to the fact that the formwork support is high, and construction quality and construction safety are difficult to control. And the erection of the formwork support will influence the construction of the substructure and the construction period.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a concrete formwork operation platform of shaped steel concrete roof beam under the support frame condition is not set up is provided exactly.
In order to solve the technical problem, the utility model adopts the following technical scheme: a stiff steel reinforced concrete beam downward hanging operation platform comprises a lower frame body, an upper cross beam and a support piece, wherein the lower frame body is composed of five parts, namely a cross beam, a longitudinal beam, a secondary beam, a panel and an upright post. The transverse beams and the longitudinal beams are formed by welding I-shaped steel, the secondary beams are welded and fixed by square steel, the panels are laid by templates, and the upright columns are butted and welded with the lower frame body by the I-shaped steel. And welding a supporting piece on the stiff steel beam, and welding an upper cross beam on the upper part of the supporting piece. The upper beam is connected and welded with the upright post.
A stiff steel reinforced concrete beam downward hanging operation platform is characterized by comprising the following key steps.
The method comprises the following steps: 16# I-steel is adopted to be welded into a rectangular frame, a cross beam is additionally arranged in the middle, five longitudinal beams are additionally arranged vertically, and secondary beams are uniformly distributed on the longitudinal beams by adopting 50 multiplied by 3 square steel. And a formwork with the thickness of 18mm is paved on the secondary beam.
Step two: 16# I-steel is adopted as a stand column, and is butt-welded with the joint of the longitudinal beam and the transverse beam to form a lower frame body. And the lifting lugs are welded on the stand columns.
Step three: and welding vertical 22# I-steel with the length of 250mm on the upper part of the stiff steel beam to serve as a lower hanging platform supporting piece, and welding the upper cross beam of the platform and the supporting piece in a full-seam mode.
Step four: and lifting the lower frame body by adopting a chain block to complete the butt welding of the lower frame body and the upper cross beam. And finishing the assembly of the lower hanging operation platform.
Preferably, in the first step, 16# i-steel is adopted to be welded into a rectangular frame, and the secondary beam is made of 50 × 50 × 3 square steel to reduce the weight of the lower hanging operation platform and reduce additional construction load.
Preferably, in the second step, the upright column is made of 16# I-steel, so that the integral rigidity is high, and the lifting lugs are welded on the upright column, so that the mounting and the dismounting are more convenient.
Preferably, in the third step, the 22# I-steel is adopted to be vertically welded to serve as a lower hanging platform supporting piece, and the support is firmer.
Preferably, in the fourth step, the lower frame body is welded and assembled in advance and then integrally lifted to be connected with the upper cross beam in a welded mode, and the frame body is safer and more reliable.
Compared with the prior art, the beneficial effects of the utility model are that.
The operation platform is integrally formed by welding the I-shaped steel, the integrity and the stability are better, the operation platform is safer and more reliable, meanwhile, the I-shaped steel can be repeatedly used, the residual value is higher, and the cost is saved.
The secondary beam is made of square steel, so that the weight of the operating platform is reduced, the influence of construction additional load on the section steel beam is reduced, the panel is fully paved with the template, and the formwork supporting operation of workers is facilitated.
Due to the adoption of the lower hanging operation platform, the lower scaffold is prevented from being erected, the operation platform is prevented from being erected, the construction of the lower structure is not influenced, and the construction period is saved to the greatest extent.
The operation platform is welded and assembled on the ground, and the structure quality and the safety are more reliable.
Compared with the prior art, the utility model discloses an I-steel welds into operation platform, wholly promotes to the construction position with the steel construction, makes things convenient for the carpenter to accomplish the formwork operation of shaped steel concrete beam, also can guarantee shaped steel concrete's formwork quality simultaneously, but I-steel and square steel reuse, construction safe and reliable and cost are lower.
