Plastic Formwork Panel Edge Protector and Reinforcement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Plastic support structures for formwork panels face challenges in achieving high strength while maintaining low weight, and they are prone to edge damage during construction and handling due to the sensitivity of the formlining edge.
Innovation Solution
A support structure with edge protection and reinforcement made from different materials, such as metal or long fiber-reinforced plastic, integrated into the plastic main body to enhance load-bearing capacity and protect the formlining edge, which can be designed as a frame or strips and embedded within the plastic for added durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If plastic support structures are used for formwork panels, then weight is reduced and durability is improved, but strength is insufficient and edge protection is lacking
Solution Approach 1:
The patent applies composite materials by combining plastic with metal or long fiber-reinforced plastic elements. The support structure uses a plastic main body reinforced with metal profiles or long fibers (≥5mm) distributed throughout the plastic mass, creating a hybrid composite that leverages the low weight and corrosion resistance of plastic while incorporating the high strength of metal or fiber reinforcements to achieve both weight reduction and increased strength.
Solution Approach 2:
The patent applies local quality by providing targeted reinforcement at critical locations rather than uniformly throughout the entire structure. Edge protectors made of metal or long fiber-reinforced plastic are specifically positioned at vulnerable edge areas of the formwork panel, while the central areas maintain the lightweight plastic construction. This localized reinforcement strategy increases strength where needed without unnecessarily increasing overall weight.
2Ease of manufacture
If plastic support structures are used for formwork panels, then manufacturing cost is reduced and recyclability is improved, but edge damage resistance is poor
Solution Approach 1:
The patent applies composite materials by integrating metal or long fiber-reinforced plastic edge protectors into the plastic support structure. These composite elements are specifically positioned at the edges of the formwork panel to provide enhanced protection against damage during construction and handling, while the majority of the structure remains plastic for cost-effective manufacturing and recyclability.
Solution Approach 2:
The patent applies beforehand cushioning by incorporating edge protectors made of durable metal or long fiber-reinforced plastic materials at the vulnerable edges of the formwork panel before construction activities begin. These pre-installed protective elements absorb and distribute impact forces during handling and assembly, preventing damage to the plastic support structure and formwork skin before such damage can occur.
3Strength
If reinforcement is added to plastic support structures, then load-bearing capacity is increased, but weight increases significantly
Solution Approach 1:
The patent applies composite materials by combining plastic with metal or long fiber-reinforced plastic reinforcements. The use of long fibers (≥5mm) distributed throughout the plastic matrix creates a composite material that significantly increases load-bearing capacity while adding minimal weight compared to solid metal reinforcements. The fiber-reinforced plastic leverages the high strength-to-weight ratio of the fiber materials within the lightweight plastic matrix.
Solution Approach 2:
The patent applies local quality by concentrating reinforcement materials at critical load-bearing areas and edge zones rather than uniformly throughout the entire support structure. Edge protectors and localized fiber concentrations are positioned where stresses are highest, allowing the structure to achieve adequate load-bearing capacity with minimal overall reinforcement, thus limiting weight increase.
4Object-affected harmful factors
If edge protection is added to the support structure, then edge damage is prevented, but device complexity increases
Solution Approach 1:
The patent applies merging by integrating the edge protectors as integral components of the support structure rather than separate attachments. The metal or long fiber-reinforced plastic edge protectors are embedded within or firmly attached to the plastic main body during manufacturing, creating a unified structure. This integration reduces the number of separate parts and assembly steps compared to detachable edge protection systems.
Solution Approach 2:
The patent applies composite materials by creating a hybrid structure where metal or long fiber-reinforced plastic edge protectors are combined with the plastic support structure in a single integrated component. This composite construction allows the edge protection to be manufactured as part of the support structure itself, reducing assembly complexity while providing enhanced edge protection through the durable composite material.
