PRECAST STAIRS WITH A MODULAR HANDRAIL SYSTEM
Precast Stairs with a Modular Handrail System are the method of off-site construction for completing staircases with the benefits of safer and faster installation.
The precast concrete stairs are manufactured for Kwik RC Frames and are then delivered to the specific project.
The modular Handrails (manufactured to our client’s specification and Architect’s handrail detail) are then attached to the precast stairs via a special connection system that is installed in the precast stairs when they are being manufactured.
InstallationThe precast stair sets are transported to the project location by Kwik RC Frames.
Stairs are unloaded and placed in a designated laydown area.
Exclusion zone will be set-up around the lifting area and staircase access will be temporarily closed.
Precast Stairs with modular handrail system will be lifted using special sockets attached to the lifting bolts that are cast-in during cast-in process.
The stair flights are lowered down in the staircase and placed onto the designated landings.
The stairs are then bolted to the steel bracket on the landing.
Temporary edge protection is set up on the main landings.
The Kwik Site operatives will grout the bolt-in anchor extensions as a final step once the final survey and sign off has been carried out by our Site Engineer.
Compared to the traditional method instalation time is reduced dramatically (See video on the bottom of the page).
The installation method only requires the following steps:
Step 1: Lifting
Step 2: Landing
Step 3: Bolting
The installation proccess can be listed in 3 simple steps. The proccess takes between 10-15 minutes for each precast stair flight.
The level of safety is the number 1 priority when deciding which method will be used to construct the stair flights for the project.
With the new off-site precast stairs and associated modular handrail system which is set-up prior to installing safety comes first as this offers a ready to use safe system of access once the installation is complete and signed off by or site engineer.
Safety is further enhanced by the removal of all the traditional methods of constructing a staircase on site using a formwork team for shuttering and making the mould, followed by the steel fixing team for making the reinforcement skeleton, followed by concrete team to pour the concrete stairs and then the requirement for carpenters / general operatives to strike the staircase shutters once the stair flight has cured.
The scaffolders then have to install a temporary handrail on the stairs, maintain this and sign it off on a weekly basis, then to co-ordinate the removal of the temporary handrail when the handrail company are on site to fix and weld the permanent handrail on the stair flights.
All these multiple tasks add numerous safety risks to the site operations associated with these works. There is also a vast amount of time, effort and money spent controlling all these risks. By removing all these multiple site processes we have drastically diminished the risk associated with constructing and installing stair flights on site.
