[0002] Stairs are an essential part of building structures. With the increasing use of high-rise buildings and steel structure buildings in the construction industry, various forms of stairs have also been greatly enriched. On the premise of ensuring the traditional functions of stairs, The special-shaped stairs with beautiful appearance are also widely used. At present, the stairs often used are concrete stairs; the construction process of traditional concrete stairs is mainly to install formwork on site, bind steel bars, pour concrete, remove formwork, and decorate the surface; In the case of special-shaped structures, the installation and construction of special-shaped staircase formwork is difficult, and the length of the stair treads is relatively large, resulting in lower connection strength of the treads, which may cause fracture and serious deformation, which may cause serious safety accidents

Embodiment Construction
[0025] Below, the present invention will be further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of not conflicting, the various embodiments described below or the technical features can be combined arbitrarily to form new embodiments. .
[0026] Such as Figure 1-2 The construction method of a kind of steel structure special-shaped staircase shown, comprises the following steps:
[0027] Frame construction steps: build a reinforced wall frame on the ground;
[0028] The construction steps of the embedded parts: welding the first embedded steel structure 10 on the top of the reinforced wall frame, and burying the second embedded steel structure 20 on the ground;
[0029] The construction steps of the shaped steel 31: weld the two sides of the shaped steel 31 to the first steel structure embedded part 10 and the second steel structure embedded part 20 respectively; in this way, the inst...

The invention discloses a construction method of a special-shaped staircase with a steel structure, which comprises the following steps: a frame building step: building a reinforced wall frame on the ground; a construction step of embedded parts: welding a first steel structure pre-embedded on the top of the reinforced wall frame The second steel structure embedded part is buried on the ground; the steel structure construction step: weld the two sides of the steel structure to the first steel structure embedded part and the second steel structure embedded part respectively; the pedal construction step: the steel pedal One side is welded on the profiled steel, and the other side of the steel pedal is processed to form a fixed part; the fixed part is extended into the reinforced wall frame and welded to the reinforced wall frame; concrete beam construction steps: pour concrete into the profiled steel and make it The concrete completely wraps the section steel to form a concrete beam; pours concrete to the reinforced wall frame and makes the concrete completely wrap the reinforced wall frame and the fixed part to form a concrete wall. The invention can obtain steel structure special-shaped stairs with better strength, and reduces construction difficulty.
Description
technical field [0001] The invention relates to a construction method of a staircase, in particular to a construction method of a special-shaped staircase with a steel structure.
