Embodiment 1

[0037] Such as Figure 8 Shown, this prefabricated assembly type staircase construction method comprises the following steps ( Figure 8 The brief steps are shown in , and the specific steps are subject to the content disclosed in the manual):

[0038] S100. According to the design requirements, the stair section 2 and the upper and lower rest platforms 1 are manufactured in the same batch in the manufacturing project, and one stair section 2 and two rest platforms 2 are used as a prefabricated unit to form a prefabricated assembly staircase hoisting unit, and at the construction site. The stair beam 4 is constructed; the construction period can be greatly reduced like this.

[0039] Among them, such as image 3 As shown, the lower part of the rest platform 1 is provided with two rib beams 6, and the upper stress rib 12 and the lower stress rib 13 are extended from the side of the rest platform 1, and the end of each rib beam 6 is provided with a reserved Bolt hole 8. Each...

Embodiment 2

[0049] The prefabricated assembled staircase is manufactured by using the construction method of the prefabricated assembled staircase in Embodiment 1.

Abstract

The invention relates to a prefabricated stair and a construction method thereof, and the scheme comprises the following steps: S100, prefabricating a stair section and an up-down rest platform, and constructing a stair beam; s200, the bottom hoisting supporting rods are vertically arranged and installed between the two ribbed beams, and a hoisting connecting system of the prefabricated floor slab is formed; s300, the rest platform is hoisted to a stair beam which is constructed in advance, after alignment, the hoisting connecting system is dismantled, and the prefabricated assembly type stair hoisting units are fixed through split bolts; s400, after the prefabricated assembly type stair hoisting units which are adjacent up and down are installed every time, joint treatment is conducted between every two adjacent rest platforms; and S500, the step S200 to the step S400 are repeated till construction of all the prefabricated assembly type stair hoisting units is completed, and finally the stair handrail is installed. The hoisting device has the advantages of being reasonable in structure, high in integrity, high in hoisting efficiency and good in installation quality.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a prefabricated assembled staircase and a construction method thereof. Background technique [0002] Reinforced concrete stairs can be divided into two types according to the construction method: cast-in-place and prefabricated. The cast-in-place reinforced concrete staircase is formed by setting up formwork at the construction site, binding steel bars and pouring concrete. The construction speed of this kind of cast-in-place stairs is slow, the formwork consumes a lot, and it has adverse effects on labor force and construction period. Moreover, the construction quality defects of cast-in-place stairs are many, and problems such as mold expansion and grout leakage are prone to occur. Walking back and forth can easily damage the edges and corners of the steps. The prefabricated reinforced concrete staircase divides the staircase into three parts: the rest board,...
