Embodiment Construction
[0049] Before the construction method of a separate prefabricated staircase described in the present invention was not adopted, the stair slab width of the original prefabricated staircase was 1160mm, the weight was 4.2t, and the dead weight was too large, which exceeded the capacity of the mainstream tower cranes in the current high-rise residential construction site The scope cannot meet the construction needs.
[0050] Such as Figure 1 to Figure 6 Shown, the construction method of a kind of separated prefabricated staircase of the present invention comprises the following steps:
[0051] Step 1. Deepen the design of the prefabricated staircase drawings;
[0052] Before construction, the design drawings were deepened, and the prefabricated staircase separation construction technology was adopted to divide the entire prefabricated staircase into two along the width direction of the stair slab. The width was reduced from 1160mm to 580mm, and the weight was reduced from 4.2t ...

Abstract
The invention discloses a construction method of a detachable prefabricated staircase. The concrete steps include deepening design of a drawing of the prefabricated staircase, production and site stacking of the prefabricated staircase, installation preparation, hoisting and positioning of the prefabricated staircase, joint embedding, grouting curing and finished product protection after installation of the prefabricated staircase. The invention provides the construction method of the detachable prefabricated staircase. The method is easy, safe and reliable to operate, effectively ensures engineering quality, improves hoisting efficiency, shortens the project period, reduces project cost, and also can drive assembly structures to promote the development of national housing industrialization. At the same time, the method is also conducive to energy conservation, emission reduction and environmental protection, and can be widely used in the field of assembly buildings.
Description
technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a construction method of a separated prefabricated staircase. Background technique [0002] With the rapid development of my country's economy, the rise of labor costs, the processing accuracy and quality of prefabricated components, the improvement of construction technology and management level of prefabricated construction, especially under the trend of industrialization of residential buildings in my country, prefabricated The application of prefabricated buildings is gradually heating up and showing a trend of rapid development. In order to promote the pace of industrialization and modernization of the construction industry, some enterprises start with prefabricated stairs based on the principle of simple to complex, and use this as a pilot to realize the gradual promotion of prefabricated building structures. However, according to the feedback from...
