Formwork is a crucial element in the construction industry. It must be designed, fabricated, erected and supported while later on, it also has to be removed and maintained. It acts as a crucial part to support all the vertical and horizontal loads that are erected.
Here are some of the best practices for erecting concrete formwork with safety
The drawings and design should include all the layouts and working decks with the necessary scaffolding details. Once all these details are in place then the shoring equipment should be directed to determine the other requirements for a formwork.
Avoid using shoring equipment that is already damaged or overused. To make sure that the equipment is up to the mark, it should be inspected thoroughly before use. It should also be inspected after the concrete use as well. The inspection stage should also cover the inspection of all the components and weakened types of equipment. Checking all the bases is important for shore heads, base plates, extension devices and other screws. It needs to be firmly secured with foundation and the form.
Concrete adds significant weight to the formwork and all the other equipment, the loads must be checked prior. One needs to make sure that the equipment can carry the load with ease. To make sure that the formwork stays with ease, a qualified designer can be the best practice to recent a piece of shoring equipment. To know more about the services, click here.
The equipment should also be vertically aligned and spliced to prevent any type of misalignment. The bracing should be in the perpendicular direction of the spicing level to have accurate formwork.
In the case of hardened concrete, it offers additional lateral stiffness to the entire formwork while concreting the slab. One needs to also be sure of the soil’s bearing capacity before the start of the construction, to avoid any last-minute changes. In case the bearing capacity is a questionable aspect then it can be stabilized by tamping or by covering it with crushed stone. Even in cases of localized failure, these formworks can be designed to prevent any form of progressive collapse.
For cast-in-place concrete, one needs to be more careful while planning, designing and inspecting the formwork.
All formwork must be thoroughly maintained with all the design tolerances that are specified for plumpness. All the vertical slip forms must have scaffolds or work platforms for employees to work with ease. Reinforcing the steel for walls, piers, columns and other vertical structures must be done to support overturning and any form of collapse. Care should also be taken to prevent the unrolled wire mesh from recoiling again.
A good formwork ensures that the erected framework is established as per ideal construction practices by avoiding any form of undesired events. It also saves the site work from delays while saving cost. When the project begins with initial safety, it guarantees smooth functioning in the later stages as well.
