Problems solved by technology

[0002] The design and construction of the existing building stairs usually only consider the alignment of the reinforced concrete structure layer, ignoring the influence of the pavement layer for later decoration, resulting in the inability to align the up and down steps after the stair pavement, which in turn causes the handrails to fail to align. Positively, it will not only affect the quality perception of the stairs, but also cause the handrails to be lengthened due to dislocation at the platform, thus affecting the clear width of the staircase platform. Increase the workload of rework. On the other hand, it will reduce the height of the original stair platform beam, resulting in a reduction of the stair carrying capacity, which is not conducive to the safety of the stair.

Embodiment Construction

[0059] Such as figure 1 with figure 2 A construction method of a reinforced concrete staircase structure shown, the method may further comprise the steps:

[0060] Step 1. Obtain the design parameters of the original reinforced concrete staircase structure:

[0061] Step 101, obtain the horizontal distance between the axes of two adjacent stair platform beams, and record the horizontal distance between the axes of two adjacent stair platform beams as the total length L of the stairs 0 ; Wherein, two adjacent stair landing beams are located at both ends of a run of stairs;

[0062] Step 102, record the two adjacent stair platform beams as the stair platform beam 301 of the starting section and the stair platform beam 302 of the stop section, and obtain the axis of the stair platform beam 301 of the starting section and the horizontal distance of the kick surface of the starting step 201 after the concrete pouring is completed And record it as the length of the initial secti...

Abstract

The invention discloses a construction method of a reinforced concrete stair structure. The method comprises the following steps that 1, design parameters of an original reinforced concrete stair structure are obtained; 2, design parameters of the reinforced concrete stair structure is optimized; 3, a reinforced concrete stair is constructed; 4, temporary guardrail construction is conducted; and 5, a stair pavement layer is constructed. The construction method is simple in step and reasonable in design, stair steps are optimized, and therefore the influence of the laying thickness is eliminated, alignment of the laving layer of the stair steps is achieved, the quality impression and safety of the stairs are greatly improved, a large amount of rework is avoided, and the repairing cost is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of building stairs, and in particular relates to a construction method of a reinforced concrete staircase structure. Background technique [0002] The design and construction of the existing building stairs usually only consider the alignment of the reinforced concrete structure layer, ignoring the influence of the pavement layer for later decoration, resulting in the inability to align the up and down steps after the stair pavement, which in turn causes the handrails to fail to align. Positively, it will not only affect the quality perception of the stairs, but also cause the handrails to be lengthened due to dislocation at the platform, thus affecting the clear width of the staircase platform. Increase the workload of rework. On the other hand, it will reduce the height of the original stair platform beam, resulting in a reduction of the stair carrying capacity, which is not conducive to the safety of the ...
