Need for technology to minimize formworks for cost and environmentFormworks are essential for engineering methods using concrete, but it is desirable to minimize them to save manpower and cost, shorten construction period, and improve work environment. One way to minimize formworks on site is to adopt non-dismantled beam forms, which can be used permanently.
Many workforce input
Conventional formwork method
Generation of waste materials
Development of WINHI_BEAM
Minimization of formworks (factory finished products)
Reduction of field manpower and material input
Improvement of site environment through non-dismantled beam form
Sites applying WINHI_BEAM can minimize field manpower and material input and reduce waste materials.
New paradigm of beam form: non-dismantled beam formWINHI_BEAM plays the role of a form required for concrete pouring. These non-dismantled beam forms are manufactured precisely in the automated line of WINHITECH and once installed, they are not removed permanently. A 1.0T galvanized steel sheet is produced through a forming line in the plant into a plate with the structural performance of temporary materials, and undergoes assembly process. Then it is installed on site to play the role of a form.

Reduction of manpower input to the site through pre-production in the factory
Reduction of material cost through systematic production/assembly planning
Construction period shortening effect
Reduction of material / labor costsLabor and material costs for site installation and factory production are less than 5% and indirect cost (shortened construction period) is less than 25% of those of the conventional formwork Labor cost and material loss are saved due to pre-production in the factory.
Shortened construction periodBecause WINHI_BEAMs are used instead of the conventional forms, installation is simple and there is no need to remove forms after concrete hardening. Site installation process is simple due to factory production, and frame construction can be performed simultaneously at the site and factory. The application of WINHI_BEAMs can shorten construction period by approximately 15% compared to the conventional formwork. The effect of climate conditions is small.
Only minimum open stock yard is required because materials can be transported in accordance with the installation process.
Site transportation/equipment installation after factory production (no dismantling)
Site construction manpower can be minimized because site formwork is unnecessary.
Site management is easy because temporary materials are minimized (only support are installed).
Spacers are not necessary.
Column pre-pouring and simultaneous pouring methods can be applied.
Column pre-pouring method
Column formwork is simple
Deformation during pouring can be prevented
Dismantling of column forms can be minimized (reusable)
A separate process is generated (advantageous for sequential construction method by area
→ Column forms reused in later columns)
Column simultaneous pouring method
Each floor can be completed in one process.
Column formwork is complex
Frame behavior deformation during pouring is possible (coping is impossible)
Total column forms are dismantled and reassembled.
Significant reduction in incident rate because the conventional form installation and dismantling process is omitted.
Field workforce and safety accidents are minimized .
The T-shaped rib serves as rebar spacer to obtain rebar construction quality.
Construction quality can be maintained sufficiently with small field workforce.
Uniform covering thickness of the rebar is possible.
Excellent processability, durability, and weather resistance with galvanized steel sheet (KSD3506 – GI)
Durability and weather resistance
Comfortable work environment is possible because there are less noise and dust on the site due to forming and production in the factory.
Low-carbon eco-friendly construction method can be realized by minimizing construction wastes and reducing CO₂ emissions.
