[0021] The specific embodiments of the utility model will be further described below in combination with the drawings. Wherein the same parts are indicated by the same reference numerals.
[0022] It should be noted that the words "front", "back", "left", "right", "up" and "down" used in the following description refer to the directions in the drawings, and the words "in" and "out" refer to the directions towards or away from the geometric center of a particular component.
[0023] It should be noted that when an element is referred to as "fixed to" another element, it can be directly on the other element or there can be a central element, and when an element is referred to as "connected to" another element, it can be directly connected to the other element or there can be a central element, and the terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.
[0024] In order to make the content of the utility model more easily understood clearly, the technical solutions in the utility model embodiments will be described clearly and completely below in combination with the drawings in the utility model embodiments.
[0025] Please refer to the drawings in the following Figures 1-4 Light platform prefabricated beam type stair structure, including the folded plate 1 and the platform plate 2 that are connected in the folded plate 1 both ends and are set in the form of step, the lower end of platform plate 2 is also equipped with reinforcing beam 3.
[0026] The platform plate 2 is also provided with multiple sets of reserved openings 4 at its ends. The ends of the upper and lower platform plates 2 are connected to the floor platform plates 9 through the reserved openings 4. The upper end of the floor platform plate 9 is provided with a connecting groove that connects to the bottom end of the platform plate 2. The assembly is completed by inserting a vertical beam into the reserved opening 4.
[0027] One end of each of the multiple steps on the folding plate 1 is recessed with a pre-embedded groove 5, and a pre-embedded steel plate 6 is connected in the pre-embedded groove 5. The subsequent assembly and fixing of the railing is completed through the pre-embedded steel plate 6.
[0028] In one embodiment:
[0029] The steps are also recessed along their length with anti-slip mounting grooves 7, and anti-slip ribs are connected inside the anti-slip mounting grooves 7. The anti-slip ribs can be installed through the pre-set anti-slip mounting grooves to ensure the safety of walking on the stairs.
[0030] The reinforcing beam 3 is connected to the outer end of the platform plate 2, and the lower end of the folded plate 1 is also connected to a precast crossbeam plate 8 with the same inclination. The reinforcement beam 3 and the precast crossbeam plate 8 can enhance the structural strength of the staircase.
[0031] In practical applications, C30 to C50 concrete and HRB400 steel reinforcement are used. The folded plates are thin-plate in form, typically with a thickness of 50mm to 80mm. Figure 4 As shown, a hoisting hole is also provided on one side of the upper end of the folded beam to facilitate hoisting, installation and use.
