Embodiment 1

[0048] like Figure 1-4 As shown, the installation method of the prefabricated staircase of the present invention comprises the following steps:

[0049] A. The prefabricated staircase 1 is formed, and the prefabricated staircase 1 component is molded according to actual requirements, and the upper and lower ends of the prefabricated staircase 1 are respectively provided with reserved holes 11 for installation;

[0050] Build the support system 5 and the mold required for the molding of the staircase interface 2, pour and form the upper and lower two staircase interfaces 2 connected to the two ends of the prefabricated staircase 1, and pre-embed the connecting parts in each of the staircase interfaces 2;

[0051]B. Maintain the strength of all the staircase interfaces 2 to meet the design requirements;

[0052] C. On each of the stair interfaces 2, a mortar leveling layer 3 is provided at the upper and lower contact surfaces of the prefabricated stairs 1;

[0053] D. Hoistin...

Embodiment 2

[0064] like Figure 2-4 As shown, the prefabricated staircase of the present invention includes a prefabricated staircase 1 and two staircase interfaces 2 respectively connected to its two ends.

[0065] All the stair interfaces 2 are cast-in-situ structural parts, and the prefabricated stairs 1 are provided with fixed hinge supports, which are connected to the stair interfaces 2 at the upper end, that is, the prefabricated stairs 1 can be opposite to the stair interface 2 at the upper end. Rotation, horizontal and vertical direction can not move, the prefabricated staircase 1 is provided with a sliding support, connected to the lower end of the staircase interface 2, that is, the prefabricated staircase 1 can be rotated relative to the lower end of the staircase interface 2, the horizontal direction move, and cannot move in the vertical direction; wherein, the two stair interfaces 2 are respectively connected to the fixed hinge support at the upper end of the prefabricated st...

Abstract

The invention discloses an assembling type stair and a mounting method thereof. The mounting method comprises the following steps: A, building a supporting system and a mold pouring stair interface; B, maintaining; C, setting a mortar leveling layer on the stair interface; D, hoisting a precast stair; E, correcting a precast stair; F, pouring a grouting material in a preformed hole in the upper end and sealing with mortar; G, connecting a fixed part in a preformed hole in the lower end with a corresponding part and sealing with mortar; H, protecting a finished product. By the assembling type stair and the mounting method thereof, the problems that the conventional building structure system, comprising the stair, adopts cast-in-place reinforced concrete, a large amount of brackets need to be built on the construction site and a large amount of pouring molds and mold plates need to be paved on the construction site, and time and labor are consumed can be effectively solved by splicing the precast stair on the construction site. The method is simple in construction process and good in structure formation, the construction period is greatly shortened, and manpower and material resources are saved.

Description

technical field [0001] The invention relates to a building construction method, in particular to an assembled staircase and an installation method thereof. Background technique [0002] With the continuous development of my country's economy and the improvement of people's living standards, infrastructure construction, especially the construction of buildings and houses, is becoming larger and larger. The structural systems of existing buildings, including the stairs, are all made of cast-in-place reinforced concrete. It is necessary to build a large number of brackets and lay a large number of pouring molds and formworks before pouring and molding the stairs. Such a staircase construction method is time-consuming, laborious, and costly. Contents of the invention [0003] The purpose of the present invention is to overcome the structural system of the existing buildings existing in the prior art, including that the stairs therein all adopt cast-in-place reinforced concrete,...
