Building Joint Component with Insulating Bracket for Force Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sound-insulating components for building joints, particularly in stair landings, face challenges in efficiently transmitting forces while maintaining soundproofing, often requiring complex structures and high production costs, and are not adaptable to various installation conditions.
Innovation Solution
A modular component design featuring a separating plate and shell bodies that separate functions, allowing for a flat, step-free structure with a reinforcement element that forms a bracket-like mounting projection for sound-insulating and force-transmitting connections between building parts, eliminating the need for reinforcing rods and enabling easy adaptation to different installation scenarios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If reinforcing rods are passed through the separating plate to connect the two building parts, then force transmission is improved, but sound transmission increases and the component thickness becomes larger
Solution Approach 1:
The separating plate is segmented into multiple layers (first outer layer, first intermediate layer, second intermediate layer, second outer layer) with sound insulation elements and reinforcing rods positioned in specific layers. This segmentation allows the reinforcing rods to transmit force while the intermediate layers with sound insulation elements block sound transmission paths.
Solution Approach 2:
Sound insulation elements are introduced as intermediary materials between the reinforcing rods and the building parts. These elements mediate the interaction by allowing force transmission through the rods while blocking sound transmission, thus resolving the contradiction between strength and sound insulation.
2Object-affected harmful factors
If a multi-layer structure with sound insulation elements is used in the separating plate, then sound insulation is improved, but the component thickness and production complexity increase
Solution Approach 1:
The separating plate is divided into four distinct layers with specific functions assigned to each layer. This segmentation allows for optimized sound insulation performance while maintaining a systematic and manageable structure that can be manufactured using standard processes.
Solution Approach 2:
The separating plate structure is designed to simultaneously fulfill multiple functions: structural support, force transmission through reinforcing rods, sound insulation through intermediate layers, and positioning of components. This multi-functionality reduces the need for additional separate components, thereby managing complexity.
3Strength
If the separating plate has a stepped cross-section to accommodate reinforcing bars, then force transmission is improved, but the installation precision requirement increases and adaptability to different positions decreases
Solution Approach 1:
Instead of shaping the separating plate with a stepped cross-section to accommodate reinforcing bars, the invention inverts the approach by providing holding means on the reinforcing rods themselves. This allows the separating plate to maintain a simple, flat cross-section that can be universally applied to different installation positions while still ensuring proper force transmission.
Solution Approach 2:
The reinforcing rods are designed with integrated holding means that can accommodate different bar diameters and configurations. This universal design allows the same separating plate structure to be used in various installation positions (horizontal, vertical, inclined) and with different reinforcing bar specifications, greatly enhancing adaptability.

Function Achieved in This Case
This design reduces costs and simplifies assembly, provides effective soundproofing and force transmission, and allows for versatile installation in various building configurations without compromising the vertical separation plane, ensuring precise alignment and efficient force transfer.
Implementation Method 1
the second part of the building is supported in a height-adjustable manner on the support with the interposition of an elastomer bearing
Implementation Method 2
for the sound-insulating, force-transmitting connection of adjacent parts of the building
Implementation Method 3
anchored in the soft intermediate layer of the separating plate in the building element, which thus dampens the transmission of vibrations between the outer layers and between the outer layers and the rebars

AI summary
The component has a partition plate (1), where a reinforcement element (3) passes through the separation plate. The partition plate has a through opening (1d) for the reinforcement elements, where a trough-shaped shell body (6) of the partition plate is formed in the region of the opening. The reinforcement element proceeds and starts from one of two building sections (A,B) and projects at the through opening into the shell body. The reinforcement element cooperates with an insulating element (5) for sound-insulated power transmission between the two buildings.
