Adjustable Pipe Fastening for Reinforcement in Tight Concrete Spaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pipe fasteners for attaching pipes to reinforcement in concrete structures are cumbersome and difficult to install, especially in areas with limited space and variable concrete covers, as they lack adjustability and flexibility.
Innovation Solution
A pipe fastening system comprising a tubular base body with a wing-shaped holder that is adjustable in both longitudinal and circumferential directions, featuring a locking mechanism and a rotatable adapter for flexible installation, allowing for secure attachment to reinforcement with adjustable positioning and easy cable insertion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If pipe fasteners are designed with fixed positioning for reinforcement attachment, then they provide stable attachment, but they cannot accommodate variable concrete covers and are difficult to install in limited spaces
Solution Approach 1:
The holder is designed with adjustable positioning capability along the pipe axis, allowing it to adapt to different concrete cover thicknesses. The holder can be positioned at multiple locations on the pipe circumference and adjusted axially to maintain proper spacing between reinforcement and formwork regardless of varying concrete cover requirements.
Solution Approach 2:
The pipe fastening device is divided into separate functional components: a pipe section with integrated holder, and a separate reinforcement attachment component. This segmentation allows the holder to be independently adjusted on the pipe while the reinforcement attachment mechanism can be independently positioned, providing flexibility for both concrete cover adaptation and installation in limited spaces.
2Reliability
If pipe fasteners are designed with precise fit for pipe ends, then they secure the pipe end properly, but they become bulky and difficult to install in areas with limited space
Solution Approach 1:
The holder is integrated within the pipe wall structure, with the pipe end inserted into the holder from the rear. This nested arrangement allows the pipe fastening device to maintain a compact profile that fits within the pipe dimensions, reducing bulkiness while still providing reliable pipe end securing through the integrated locking mechanism.
Solution Approach 2:
Instead of extending outward from the pipe surface to secure the pipe end, the holder is designed to receive the pipe end from the rear and lock it internally. This inverted approach allows the fastening mechanism to remain compact and flush with the pipe surface, facilitating installation in limited spaces while maintaining secure pipe end attachment.
3Productivity
If pipe fasteners are attached before reinforcement installation, then they simplify the installation process, but they limit flexibility for adjusting concrete cover thickness
Solution Approach 1:
The holder is designed with adjustable positioning capability that allows it to be moved along the pipe axis after installation. This dynamic adjustment capability enables the concrete cover thickness to be modified even after the pipe fastening device has been installed, maintaining both installation efficiency and adaptability to varying concrete cover requirements.

AI summary
The invention relates to a pipe fastening (1) for securing a pipe end to reinforcement in a concrete wall. The pipe fastening (1) comprises a tubular base body (2) for receiving the pipe end in a longitudinal direction of the tubular base body (2), and at least one wing-shaped support (3) projecting laterally from the tubular base body (2). The wing-shaped support (3) serves to bear against the reinforcement and is adjustably arranged relative to the tubular base body (2).
