Integrally assembling staircase and method for fabricating same

Abstract

The invention discloses an installation entire stair and the manufacturing method, especially an installation entire helix stair. The process is that: making every step to box structure and joining the steps into an entire stair by the method of bolt or joint. The shape of the stair could be straight stair or helix stair. The invention sharply decreases the time limit for a project and the cost. Moreover, it has advantages of simple structure, low cost and easy to realize mass production.

Description

Technical field: [0001] The invention relates to an assembled integral staircase and a manufacturing method thereof, in particular to an assembled integral spiral staircase and a manufacturing method thereof, belonging to the technical field of stairs. Background technique: [0002] At present, most of the spiral staircases used in buildings in the prior art are reinforced concrete cast-in-place spiral staircases, and in individual duplex houses and multi-storey villas, small steel spiral staircases with steel column cantilevered steel ladder plates are also used. Or a spiral ladder formed by bending steel. These stairs or spiral ladders in the prior art mainly have the following problems: [0003] 1. The main problems of large cast-in-place reinforced concrete stairs or spiral ladders are: [0004] (1). It is difficult to construct and shape, and the steel content is large, which is a fact for all to see; [0005] (2). The structure is self-heavy, resulting in an increas...

AI Technical Summary

Problems solved by technology

[0004] (1). It is difficult to construct and shape, and the steel content is large, which is a fact for all to see;

[0005] (2). The structure is self-heavy, resulting in an increase in the geometric size and material consumption of the supporting structure;

[0007] (4). The cost is high, and its quota is much higher than the conventional frame beam structure;

[0008] (5). The weight of the overhang is large, which is unfavorable for the structure's earthquake resistance;

[0010] (1). In residential buildings, a false spiral ladder is often set up, that is, a steel column spiral ladder is set in the center of the spiral ladder. One end of the ladder plate is welded to the steel column, and the other end is cantilevered. The architectural effect is poor and it does not play the role of a space spiral ladder. as a last resort;

[0011] (2). The amount of steel used is large, and the cost is high;

[0012] (3). The real spiral ladder is bent into a spiral shape with section steel, and then connected to the ladder plate, because it is not one-way bending, but multi-directional spiral bending, forming is very difficult and the production cost is high

[0013] Because the spiral staircase in the prior art has the above-mentioned problems, in actual use, its use effect is still not ideal enough
