Embodiment 2

[0037] like Figure 3-Figure 4 As shown, the lower end of the pipe string 301 is provided with a mounting plate 306, and a plurality of mounting screw holes are provided on the mounting plate 306. After the lower end of the pipe string 301 is closely matched with the inclined surfaces of the first-level inclined section 104 and the second-level inclined section 203, the bolts are passed through The mounting plate 306 is locked and fixed on the primary inclined section 104 and the secondary inclined section 203 through the mounting screw holes.

[0038] The screw connection structure between the stair treads 3 and the stair body is arranged in the pipe column 301, and the mounting plate 306 can not only improve the strength of the pipe column 301, but also hide the fixing bolts and improve the aesthetics.

[0039] It has the following advantages:

[0040] (1) The lower stair section 1 and the upper stair section 2 are assembled into an L-shaped staircase body, the upper and lo...

Abstract

The invention discloses a single-steel-beam prefabricated staircase, and belongs to the technical field of fabricated prefabricated staircases. The single-steel-beam prefabricated staircase comprises a staircase body which is projected on the ground in an L shape and rises obliquely. The staircase body comprises a lower staircase section and an upper staircase section which are connected. Multi-step staircase pedals are fixed to the lower staircase section and the upper staircase section. The lower staircase section is composed of a lower steel tube beam, a bottom assembly fixing plate and an upper fixing tube. The upper staircase section is composed of an upper steel tube beam and a top combined fixing plate. Each staircase pedal is composed of a tube column, a stepping lining plate and a pedal body. The prefabricated staircase is of a single-steel-beam structure, L-shaped staircase bodies of corresponding models can be produced according to the factors such as the floor height of floors and the stair pedal spacing, the staircase pedal structure is detachably fixed and can be universally used on the L-shaped staircase bodies of various models, the application range is wide, batch production can be achieved, and the production cost is reduced.

Description

technical field [0001] The invention relates to a single steel beam prefabricated staircase, which belongs to the technical field of assembled prefabricated staircases. Background technique [0002] Assembled prefabricated stairs are usually quickly assembled from a complete set of pre-processed staircase accessories. It mainly includes stair steel beams, stair treads and related fasteners. By fixing the steel beams obliquely between the ground and the floor, and fixing several stair treads step by step on the steel beams, the assembly of the stairs can be completed. It has the advantages of simple structure, low requirements on the installation environment, and convenient installation. However, there are also the following disadvantages. For example, the existing prefabricated stairs generally adopt a one-stage structure, which is directly connected to the upper floor from the ground. The larger space cannot be used in smaller room types; in addition, the current prefabri...
