Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing methods for supporting floor elements on beams do not allow for easy disassembly and re-use of the beam and floor element without damaging the structural components.

Innovation Solution

The method involves providing elongated transverse fittings with a free end projecting out of the beam's web section, connected to a protective member, allowing the floor element to be detached by cutting through the fill material without damaging the beam or fittings, enabling re-use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If floor elements are permanently fixed to beams using traditional methods, then structural stability is improved, but reusability and ease of disassembly deteriorate

Engineering Contradiction:

Improvestructural stabilityVSAvoidease of disassembly

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The connection system is divided into separate components: the beam with embedded fittings, the fill material layer, and the floor element with recesses. This segmentation allows the floor element to be detached from the beam by removing the fill material, enabling disassembly while maintaining structural stability during use

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The elongated transverse fittings are pre-installed into the beam during beam construction, and the fill material is placed to cover them before the floor element is positioned. This preliminary preparation enables easy disassembly later by simply removing the fill material without damaging the beam or fittings

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If beams are reused in different buildings, then resource efficiency is improved, but risk of damage during separation deteriorates

Engineering Contradiction:

Improvebeam reusabilityVSAvoiddamage risk during separation

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The connection function is extracted from the beam structure itself and placed into removable fill material that covers the embedded fittings. This allows the fill material to be removed without damaging the beam or fittings, enabling safe separation and reuse of the beam in different locations

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The fill material acts as a protective cushion that covers and protects the elongated transverse fittings during the separation process. By cutting through the fill material rather than the fittings themselves, damage to the beam and fittings is prevented, ensuring they remain intact for reuse

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

AI summary

A method and an arrangement for supporting a first floor element at a beam and a beam. The beam is provided with a supporting flange section configured to support the first floor element. The method includes supporting the first floor element on the supporting flange section so that a first space is formed between the first floor element and the beam, providing elongated transverse fittings in the beam, providing transverse reinforcements to extend between the beam and the first floor element. The elongated transverse fitting have a first free end at the first lateral side of the beam, and a first protective element is connected to the first free end of the elongated transverse fitting outside the web section of the beam.
