Problems solved by technology

However, in actual operation, when the hoisted prefabricated stairs are in full contact with the upper platform and the lower platform, they will inevitably shake; Or when adjusting the ladder platform, due to the static friction or sliding friction force between the planes, it is very inconvenient to fine-tune the prefabricated stairs when they are positioned and fixed

Embodiment Construction

[0056] to combine Figure 1~Figure 2 It can be seen that the assembled prefabricated staircase includes a prefabricated staircase body 1, and the top connection end 5 and the bottom connection end 6 of the prefabricated staircase body 1 are respectively placed with the placement groove A7 provided by the upper ladder platform 2 and the lower ladder platform 3. The slots B8 are respectively connected and fixed, the top connecting end 5 is fixed to the upper ladder platform 2 through the cast-in-place concrete layer A9, and the bottom connecting end 6 is fixed to the lower ladder platform 3 through the cast-in-place concrete layer B10.

[0057] The middle part of the prefabricated staircase body 1 is fixed with a plurality of parallel longitudinal ribs A13 along the length direction of the staircase body 1. The folds are bent longitudinal ribs 18 arranged along the top connection end 5 and the bottom connection end 6 .

[0058] The ends of the bent longitudinal ribs 18 protrude...

Abstract

The invention discloses an assembling method of an assembled prefabricated staircase, which comprises the following steps: fixing the platform of the upper ladder and the platform of the lower ladder, hoisting the body of the prefabricated staircase so that the top connecting end corresponds to the upper ladder platform, and the bottom connecting end corresponds to the lower ladder The platform is corresponding, and then the positioning protrusion of the top connection end is positioned with the positioning groove of the upper ladder platform, and the prefabricated staircase body is adjusted to fix the top connection end and the upper ladder platform, and the bottom connection end and the lower ladder platform respectively. As can be seen from the above structure, the assembling method of the assembled prefabricated staircase of the present invention is simple and convenient for the stair installation and assembly operators, and is particularly convenient for the positioning and assembling of the prefabricated staircase, the upper platform and the lower platform; Very high, reducing the labor intensity of the operator.

Description

technical field [0001] The invention relates to the technical field of a prefabricated building, in particular to an assembling method of an assembled prefabricated staircase. Background technique [0002] In the course of the development of my country's construction industrialization, prefabricated structures have been widely used. In the current traditional building construction process, most of the construction of the stairs is cast-in-place structure. The traditional cast-in-place staircase structure is difficult to form on site, the quality of the construction joints is not easy to control, and the amount of labor and wood consumption is large. With the construction industry The continuous innovation and development of the market, the continuous increase in the price of labor force in the market, and the increase in construction costs caused by it, the construction industry must gradually develop in the direction of industrialization and factoryization. As the prefabric...
