Green Formwork System

[edit] What is Luriel green formwork? - Specifications of formwork

Luriel Green Formwork System is an advance steel framing panel-prop formwork system which allows early striking operation. It provides a suitable formwork solution to most concrete structures and components and meets the general requirements of different construction methods and conditions.

With the increased emphasis on large infrastructure building and high-rise construction, the need for efficient formwork and shoring systems has grown. It's an efficient system concrete formwork.

[edit] Why choose green formwork?

Today, formwork and shoring systems are integral parts in formwork construction. It is also the foremost important trade in the reinforced concrete construction works implementation which leads and determines the smooth flow of all subsequence construction activities. With the increased emphasis on large infrastructure building and high-rise construction, the need for efficient formwork and shoring systems has grown. Building construction formwork plays an import role in the whole project. To choose what kind of the building formwork is also crucial.

As a slab formwork system,Luriel GREEN FORMWORK panelized slab formwork allows fast as well as safe forming operations with a systematic assembly sequence. The low weight of the panels, compact dimensions and practical design of the system components facilitate non-tiring and ergonomic working operations. It has been designed for standard use in constructing slabs with thicknesses up to 30 cm. GREEN FORMWORK 's range of applications extends from residential construction through to real estate construction projects.

The systematic assembly sequence and lightweight system components made of steel accelerate working operations. In addition, the possibility of early stripping with the drophead system reduces on-site material requirements. For concrete formwork construction, striking concrete formwork will boost the construction schedule.

Infill areas are reduced to an absolute minimum. Furthermore, the system makes a convincing case with an extensive range of safety and logistical accessories.

A further advantage is the easy horizontal transportation of formwork materials as the small prop requirements ensure more freedom of movement under the slab formwork. At the same time, green formwork is capable of working with other system like wall formwork systems.

[edit] Early stripping mechanism

Based on the concept of IBS Construction, green formwork , a panel-prop concrete formwork system with early-striking mechanism has been developed. It is a puzzle style system, which offers faster erection and stripping time than conventional shoring systems, directly increases financial return.

Thanks to the early-striking feature, green formwork actually performs and requires a much shorter construction cycle between 4-7 days. Hence, the system can produce concrete work area of 4-7 times its own surface area monthly; this is almost three times the productivity of conventional timber method.

With Green formwork early stripping mechanism, we can use only 1 set of panel + 2 sets of props/shroing system to cycle for the whole project which will save the cost on material compared with the traditional formwork with plywood.

The six directions self locking system ensures that the stability and safety, at the same time, the prop also provide the room for infill beam to meet the need of traditional formwork users in 12mm.

[edit] Formwork and shoring system and infill accessories

The concept of green formwork is a building method and technology that uses the Earth’s natural resources efficiently and in an environmental friendly and responsible manner. The only consumable components of green formwork, the bamboo plywood boards are made from renewable resources. Bamboo is considered an ecological construction material as it is harvested through massive agro-replanting. In other words, there is no cutting down of trees, thus it reduces damage to the environment. The main steel components (stripping head) are cast with recycled steel resources. All components are designed and manufactured for many times of reuse and last longer than timber methods. By employing green formwork a project will significantly reduce the generation of debris and waste on site.

[edit] The whole formwork for concrete systems contains:

[edit] Formwork Panel/Formwork Shuttering - Concrete Formwork Panel

Size from 1.8m x 1.2 m to 0.6m x 0.6m - Green frame which is made of Q345B with high quality.

[edit] Prop/Shoring System - Formwork Props - Prop System

Load capacity of the prop from 37KN at the height of 2.3m to 20.1KN at the height of 3.5m with 2:1 safety factor.

Shoring formwork from 2.2m to 3.5m without the tripods.

[edit] Infill Beam

For the area around the column wall where the green formwork pane can't reach, we suggest the concrete forming contractor to use the traditional plywood with thickness 12mm

[edit] How does the system solve the situation when the area is smaller than the regular panel

• The area around the column and wall could use the infill beam of green formwork with the traditional plywood whose thickness is 12mm to infill.

• In this way, the one who stores the traditional formwork could still consume in the current or new project instead of material waste.

[edit] Green formwork advantages

Green formwork is an effective replacement for conventional timber It has advantages such as safety, high efficiency, and reduced construction cost and labour.

Green formwork is simple and innovative. It comprises three basic components which are the main panel with bamboo plywood board on top of a steel framing, adjustable steel prop with early-striking head and aux beam to treat infill area. A lower support head can be added to the steel prop and enable split levels. The system can hence handle any structural layout design efficiency.

• Efficient: Installation speed up to 100 sqm/person/day for post tension slab
• Long duration: Bamboo Plywood ensures that duaration is 50 times at least for casting on the surface.Steel frame with industrial glue could also protect boundary of the bamboo plywood to make sure the whole system is operational.
• Environmental friendly: Reduce rubbish like plywood cutting. With green formwork system you don't need to cut the panel of the green formwork system. More convenient for cleaning the site.
• Save labour: Could save 50% labour and improve and boost the construction schedule.
• Compatible with traditional plywood: With green formwork system infill beam, the traditional plywood is also possible to be involved. Only with the requirements for the thickness with 12mm. And green formwork could also work with other wall formwork and column formwork system.

[edit] How to unstall

• 1.Adjust the steel props to the required length
• 2.Erect the steel props using gate brace
• 3.Hang the Panel to the Prop Head
• 4.Swing the lower end of the Panel to position using ADT
• 5.Insert, push, straighten and lock in the fourth Props
• 6.Repeat steps 3,4 & 5
