Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction, in particular to a cantilever canopy and door and window integrated construction method. BACKGROUND

[0002] In the construction field of the first floor entrance of residential buildings, office buildings, shopping malls, hospitals and other buildings, the installation quality of the cantilever canopy and door and window system directly affects the building use function and safety. At present, in the industry, the canopy and the door and window are designed and constructed separately, and there are many technical pain points.

[0003] The traditional construction often fixes the canopy on the main structure of the building through the rear embedded part, needs to drill holes on the wall or beam to implant anchor bolts, and then connect the canopy connecting piece. However, when the first floor height is high, the distance between the canopy and the outer door is too large, which cannot effectively block the rain and destroys the coordination of the building appearance.

[0004] Some schemes directly fix the canopy on the broken bridge aluminum alloy window frame by drilling holes in the window frame and connecting with screws. However, the aluminum alloy window frame is only designed to bear its own wind pressure and opening and closing force, and the additional load of the canopy will cause uneven stress of the window frame, which is easy to deform for a long time, affecting the sealing of the outer window; and when the height is high, the wind pressure increases, and it is difficult to ensure the stability of the canopy by fixing it on the window frame only, which has safety hazards.

[0005] At the same time, the size of the window frame is often inconsistent with that of the door frame, the sealing at the joint is not tight, which is easy to cause rainwater leakage, not only interfering with the use of the building, but also damaging the structural durability. In addition, the wires of the access control, emergency lighting and other facilities of the first floor entrance cannot be pre-buried, but can only be laid outside, which is not only not beautiful, but also has safety risks.

[0006] The existing construction method has defects in function, safety, sealing and facility wiring, and it is difficult to meet the actual needs, and an integrated construction method is needed to solve the above problems. SUMMARY

[0007] The purpose of the present application is to provide a cantilever canopy and door and window integrated construction method to solve the problems raised in the background.

[0008] To achieve the above purpose, the present application provides the following scheme:

[0017] Further, in step S3, the canopy support structure is an I-beam or truss structure for bearing the canopy panel, which is fixed to the outer side of the steel column or the predetermined connection point by a reserved connection plate or direct welding.

[0018] Further, in step S2, after the corrosion protection treatment, it further includes: filling the internal space of the steel column and the beam with thermal insulation rock wool material, and after filling, wrapping the outside with decorative aluminum plate matching the color and material of the window frame.

[0019] Further, in step S4, the window frame and the door frame are bolted to the steel column through the reserved bolt hole, or are welded to the steel column through the connecting piece.

[0020] Further, in step S5, the filling, leveling and sealing treatment includes: filling the inside of the connection gap with a foaming agent, leveling after curing, and then applying sealant along the edge of the gap to form a double-sealing barrier.

[0021] Further, in step S5, after the sealing treatment, it further includes: installing and fixing the canopy panel on the canopy support structure.

[0022] Further, in step S2, when the steel column construction is carried out, the wire pipe or wire slot for the access control system, emergency lighting system or weak current facility is simultaneously pre-buried into the internal cavity of the steel column, and necessary maintenance openings and outlet openings are reserved, so that the complete concealed layout of the wire is realized.

[0023] Further, the cantilevered canopy and door and window integrated construction method can be used for door and window construction at the entrance position of the first floor of a building, and the door and window includes an outer door, an outer window or any combination thereof.
