Embodiment Construction

[0029] like figure 1 , figure 2 As shown, a light-weight concrete staircase is an integral structure composed of a side plate beam 1 and a ladder plate 2. The step board 2 is provided with a tread reinforcement 7, and the side plate girder 1 is provided with a truss type reinforcement 6, and the tread reinforcement 7 is connected with the truss type reinforcement 6 as a whole.

[0030] like image 3 , Figure 4 , Figure 5 , Figure 7 As shown, the edges of the side girder 1 and the ladder plate 2 are provided with wrapping edges 5 for preventing collision and enhancing strength. The wrapping 5 can be made of bent steel plates or other shaped steels. Both sides of the wrapping 5 are comb-shaped and extend into the inside of the concrete. The comb-like shape can make the wrapping 5 and the concrete combine more tightly and firmly. The hemming 5 is welded together with the side plate beam 1, the pedal steel bar 7 inside the ladder plate 2, or the truss type steel bar 6. ...

Abstract

The invention relates to a lightweight concrete step comprising an integral structure comprising side plate beams and step plates. The edges of the side plate beams and step plates are covered for preventing collision and enhancing the strength; the covered edges are welded to step steel bars or truss steel bars, and two sides of the covered edges are in comb tooth shapes and extend into the cerement. The lightweight concrete step is high in entire force bearing performance, high in strength and shock resistance, convenient to suspend and connect and high in construction speed, is adaptive to standard large-scale production and can be applied to modular fast construction.

Description

technical field [0001] The invention relates to the field of construction, in particular to a building staircase and a manufacturing method thereof. Background technique [0002] Concrete stairs are often used in construction, and existing concrete stairs are generally manufactured by cast-in-place or prefabricated methods. In the process of building construction, especially in the process of rapid modular construction of high-rise buildings, the existing concrete stairs have the following disadvantages: (1) The overall mechanical structure of the concrete stairs is poor, and the earthquake resistance is poor; (2) The steps and steps The connection method is complicated and the connection is easily damaged; (3) The structure of the concrete staircase is not suitable for large-scale factory production, it is not convenient for transportation and hoisting, and it cannot be quickly modularized. [0003] In order to overcome the above problems, the applicant invented "a concret...
