Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that: due to the long length of the prefabricated staircase, it is easy to collide with foreign objects or be pressed down by foreign objects during transportation, and the thickness of the connection between adjacent steps is relatively thick. Small, there is still room for improvement as there is a risk of fracture at the joints when the prefabricated staircase is under pressure

Embodiment Construction

[0036] Contraction below Figure 1-3 Further detailed description of the present application.

[0037] The present application discloses a prefabricated staircase and its installation process. Refer figure 1One prefabricated staircase includes a substrate 1 that is inclined, two mounting tables 3 that are fixed at the upper beam and the lower beam, respectively, and several block step units 2, respectively. The two-piece mounting table 3 is connected to the side of the bottom plate 1, and the connecting groove 31 communicates with the upper end surface of the mounting table 3, and the bottom plate 1 is embedded with several root connecting tubes 13, and several connect tubes 13 all along the bottom plate 1 length. The direction extends and the connecting tube 13 projects both ends of the bottom plate 1, and the plurality of connect pipes 13 are distributed in the width direction of the bottom plate 1. The two ends of the connecting tube 13 are respectively engaged in the connecting...

Abstract

This application relates to a prefabricated staircase and its installation process, which includes a bottom plate arranged at an angle, two installation platforms respectively arranged at both ends of the bottom plate in the length direction, and several stepping units. The stepping units are distributed along the length direction of the bottom plate. The bottom plate is provided with a card slot extending along the length direction of the bottom plate, and each step unit is provided with a clip that is engaged with the clip slot on the side facing the bottom plate, and the inclined upper end of the bottom plate is provided with a card for entering the card slot the gap. The present application has the effect of reducing the occurrence of breakage of prefabricated stairs during transport.

Description

Technical field [0001] The present application relates to the technical field of building components, in particular, involving a prefabricated staircase and its installation process. Background technique [0002] At present, the stairs are important components for vertical traffic in the building in the building. The preparation method is mainly divided into two types and prefabricated. The current plasticity of the reinforced concrete can be used to have a total structure, and the scope of application is Wide, but has a difficulty of difficulty, the construction process is cumbersome, and the construction period is equal. In order to solve the difficulty of traditional cash-in-spot staircase, the problem of long construction period is prepared. The prefabricated staircase uses first production to transport to the construction site for installation. [0003] In the relevant technique, the installation tables at both ends of the prefabricated stair length direction are fixed to th...
