Rapid Delivery for High-Rise Building - Tunnel Formwork – Lianggong

Product Details

Tunnel formwork is a system of formwork that can be used during a normal cycle to cast the walls and formwork of a program. This system produces effective load-bearing structures that are widely used. The tunnel formwork space spans 2.4-2.6 meters, making it easier to subdivide and build smaller spaces.

Tunnel formwork system is used in the production of buildings like housing, jail houses, and student hostels which have monolitic structure. Depending on the size of the structure, tunnel formwork system provides casting of a fl oor in 2 days or in a single day. The buildings which produced by tunnel formwork system are cost efficient, resistant to earthquake, have minimal level of production fl aws and have reduced fi ne-structure labor costs. Tunnel formwork system is preferred for military buildings as well.

Characteristics

Building
The formwork is specially adapted for each project. The repetitive nature of the system and the use of prefabricated forms and reinforcing mats/cages simplifies the whole construction process, producing a smooth and fast operation. The techniques used are already familiar to the industry, but with tunnel form construction there is less reliance on skilled labour.

Quality
Quality is enhanced despite the speed of construction. The precise, even steel face of the formwork creates a smooth, high quality finish capable of receiving direct decoration with the minimum of preparation (a skim coat may be required). This reduces the requirement for following trades, thus providing additional cost savings and speeding the entire process.

Design 
The large bays constructed using tunnel form provide exceptional flexibility in the design and layout of the building and allow a high degree of freedom in the final appearance.

Safety
Tunnel form has integral working platforms and edge protection systems. In addition, the repetitive, predictable nature of the tasks involved encourages familiarity with operations, and, once training is complete, productivity improves as construction progresses. The minimal requirement for tools and equipment when moving the tunnel form further reduces the risk of accidents on site.
