What formwork of Liangong was used in the Jakarta Parking Building project?

1. Project Overview

The Parking Building project in Jakarta, Indonesia, is an impressive construction feat. With a single - floor area of nearly 3,000 square meters and a total of 10 floors above ground, it has drawn significant attention in the construction industry. Notably, Liangong has been the exclusive provider of formwork for this project. Throughout the construction process, Liangong's formwork has demonstrated outstanding performance, playing a pivotal role in ensuring the project's smooth progress.

2. Diverse Formwork Systems Applied

2.1 Drophead System

2.1.1 Ingenious Structure

This Drophead System is a horizontal system specifically designed for building floor slab construction. It consists of two main components: the formwork system and the support structure. The formwork system combines a sturdy steel frame with high - quality plywood. The support structure is flexibly configured according to different floor heights. For floors below 5 meters, steel props with early - stripping heads are used, while for floors above 5 meters, ring - lock scaffolding equipped with early - demoulding devices is applied, ensuring both efficient and safe construction.

2.1.2 Notable Advantages

· High - Efficiency Construction: The modular design of this system is a remarkable highlight. Its assembly and disassembly processes are extremely simple. A construction team of only 4 people can easily complete the pouring of 400 square meters of floor slabs per day. This significantly shortens the overall construction period, greatly improving construction efficiency and laying a solid foundation for the rapid delivery of the project.

· Economic and Environment - Friendly: All components within the system are highly reusable, effectively reducing building material waste and substantially cutting down project costs. At the same time, it fully aligns with the sustainable development concept of the construction industry, promoting a greener approach to construction.

· Safe and Reliable: Handrails and guardrails are carefully installed around the formwork, and the support components work in harmony. During the crucial concrete pouring process, this system can effectively resist the risks of formwork deformation and displacement, comprehensively safeguarding the safety of construction workers and establishing a strong safety line at the construction site.

· Wide Applicability: This system has strong compatibility with floor slab construction conditions. It is suitable for floor slabs with a thickness of ≥100mm and a concrete grade of C20 or above. Whether it is a residential, commercial, or industrial building project, it can be perfectly adapted, fully meeting the diverse construction requirements of the construction industry.

2.2 Flex - table Formwork System

The Flex - table Formwork System is ingeniously designed to address the challenges of floor slab concrete pouring in complex floor plans and narrow spaces. It is supported by steel props or tripod stands with different support heads. The primary and secondary beams are made of H20 wooden beams, and a special panel is used for covering. Significantly, this system can effectively handle construction scenarios with a maximum clear height of 5.90 meters, providing a practical solution for floor slab construction in special spaces.

2.3 Steel Frame System

2.3.1 Precise Application and High - Quality Composition

The Steel Frame System, as a vertical system, mainly serves the construction of building walls and columns. It is composed of a steel frame, plywood, and a fitting system. The steel frame is made of high - standard, high - quality materials, boasting excellent strength and stability. It can easily withstand the huge pressure generated during the concrete pouring process. The plywood is made of high - quality hardwood and covered with a PP plastic film on the surface, carefully creating a lightweight, durable, and waterproof formwork panel.

2.3.2 Excellent Formwork Characteristics

The plywood has a precise thickness of 12mm and can be reused up to 30 times. From a long - term cost - accounting perspective, this greatly reduces the usage cost. The formwork panel comes in a rich variety of sizes, with a height range of 600mm to 3000mm, a width range of 500mm to 1200mm, and a weight varying from 14.11kg to 130.55kg depending on the size. Moreover, the maximum working width of a single panel can be flexibly adjusted on - site according to the actual building structure size requirements, demonstrating a high degree of construction adaptability.

2.4 Circular Column Steel Formwork

The Circular Column Steel Formwork, with its all - steel structure, is dedicated to the construction of columns in the parking building project. It is made of high - standard steel materials, endowing it with excellent strength and stability to withstand the strong pressure during concrete pouring. After special surface treatment, the steel formwork has excellent waterproof and anti - corrosion properties, resulting in a smooth and beautiful surface for the poured concrete. In addition, this formwork can be reused multiple times, saving considerable costs for the project.

3. Conclusion
