A prefabricated staircase integrated with a guardrail and its construction method

Abstract

The invention discloses a prefabricated staircase integrated with a guardrail, a prefabricated air conditioner plate and a construction method thereof. The construction method of the prefabricated staircase integrated with the guardrail comprises the following steps of S1, accurately positioning and setting a guardrail embedding element on one side edge of a staircase section, and installing staircase section embedding elements and hanging points at two ends of the staircase section; S2, conveying the prefabricated staircase completed in the step S1 to a construction site, and fixedly connecting the straight section of the guardrail and the guardrail embedding element; S3, hanging the prefabricated staircase completed in the step S2 to a floor construction surface so that the two ends of the staircase section are respectively lapped on a support seat of the corresponding cast-in-plate structures, and fixedly connecting the staircase section embedding elements arranged at the two ends of the staircase section with embedded element gaskets arranged on the corresponding cast-in-place structure; S4, welding platform connecting elements between guardrails of the two adjacent prefabricated staircases; S5, using fine gravel concrete for filling, and leveling construction seams of the hanging points in the staircase section. The prefabricated staircase has the advantages that the hanging is convenient; the safety is high; the construction work procedures are reduced.

Description

technical field [0001] The invention relates to the construction field of prefabricated building components, in particular to a prefabricated staircase integrated with a guardrail and a construction method thereof. Background technique [0002] During the construction process of prefabricated stairs and air-conditioning panels, it is often necessary to take corresponding measures to ensure site safety and project quality during the construction process. [0003] In traditional construction, the method of enclosure is usually used. There are two main methods: erecting scaffolding and erecting external cantilevered guardrails on the existing wall. However, erecting scaffolding not only needs to waste a lot of raw materials, but also increases the construction cost. It will take up a lot of construction sites and have a great impact on the environment. In addition, in the process of erecting scaffolds, in order to fix the scaffolds, it is often necessary to open holes in the pr...

Problems solved by technology

However, the process of using steel pipe fasteners as the border guardrail is cumbersome, and the temporary steel pipe enclosure needs to be removed when installing the permanent structural guardrail; when the permanent structural guardrail is constructed, it is necessary to drill holes and install expansion bolts on the stairs or air-conditioning panels, which will cause problems. Seriously damage the integrity and aesthetics of stairs or air-conditioning panels, affect the quality of prefabricated buildings or air-conditioning panels, and repair the reserved part during the construction of the fixed end of the guardrail in the later stage, and the surface of the repaired part is prone to unevenness in the later construction. The problem of poor appearance

In addition, during the painting and repairing of prefabricated stairs or air-conditioning panels, it is easy to cause the crossing of the working surface to affect the construction of other processes
