Concealed handrail structure of small bay stairs

Abstract

The invention aims to provide a concealed handrail structure of small-bay stairs. The concealed handrail structure comprises the stairs. Stair partition walls are arranged on two sides of the stairs, wall grooves are formed in the two stair partition walls, are positioned above the stairs and are parallel to the stairs, and concealed handrails are arranged in the wall grooves; the concealed handrails comprise fixing columns, the fixing columns are arranged in the wall grooves, and handrails in the shapes of circular pipes are arranged on the outer sides of the fixing columns; the handrails are positioned in the wall grooves and are close to the edges of the outer sides of the wall grooves. The concealed handrail structure has the advantages that the wall grooves are formed in the stair partition walls on the two sides of the stairs, and the concealed handrails are arranged in the wall grooves and are quite stably fixed by the aid of fixing blocks and structure beams; spaces can be sufficiently utilized by the concealed handrails, and accordingly corresponding residential pool areas can be reduced; the corresponding manufacturing cost can be reduced, and service requirements can be met; the insides of stair halls are simple, and accordingly the future maintenance cost can be lowered.

Description

technical field [0001] The invention relates to the field of design and manufacture of stair handrails, in particular to a hidden handrail structure for stairs with small compartments. Background technique [0002] Generally, small bay stairwells (or small bay scissors stairwells) are separated by partition walls in the middle. After the stair railing is installed, in many cases it cannot meet the requirements of the specification for the evacuation width of the stair. To meet the requirements, it is necessary to increase the width of the stairs, which will increase the sharing and cost. According to GB50016-2014, the stairwell width is 1.10m. If handrails or railings are added, the relevant specification requirements are not met. Often there are only individual floors where there is a partition wall in the middle of the stairwell. If it is to be expanded with railings, the share and cost of other floors will increase. Therefore, it is necessary to solve the above proble...

Problems solved by technology

If handrails or railings are added, it does not meet the requirements of relevant specifications

Often there are only individual floors where there is a partition wall in the middle of the stairwell. If you want to expand it with railings, the shared cost and cost of other floors will increase.
