Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The existing connection structures between partition walls and floor slabs are prone to deformation and damage during earthquakes due to construction errors in the floor slab, leading to inaccurate attachment of wall materials to studs and potential fire resistance performance issues.

Innovation Solution

A connection structure where lower and upper runners are set back from the vertical-compartment-side end face of the floor slab, with back battens used to securely attach wall materials to studs, preventing deformation under horizontal forces and ensuring accurate attachment even with construction errors.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If runners are extended beyond the vertical-compartment-side end face of the floor slab to accommodate construction errors, then the ease of installation is improved, but the stability under horizontal forces deteriorates

Engineering Contradiction:

Improveease of installationVSAvoidstability under horizontal forces

Core Design Contradiction:

Ease of operationVSStability of the object's composition

Solution Approach 1:

Back battens are introduced as intermediary elements between the runners and the wall materials. These back battens provide additional attachment points and distribute horizontal forces more effectively, preventing the runner deformation that occurs when runners extend beyond the floor slab end face.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The connection structure is enhanced by adding elements in the horizontal dimension (back battens extending from the runners). This creates a three-dimensional connection system that better resists horizontal forces while still accommodating floor slab construction errors.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Stability of the object's composition

If runners are set back from the vertical-compartment-side end face of the floor slab to improve stability, then the stability under horizontal forces is improved, but the ease of installation deteriorates

Engineering Contradiction:

Improvestability under horizontal forcesVSAvoidease of installation

Core Design Contradiction:

Stability of the object's compositionVSEase of operation

Solution Approach 1:

Back battens serve as mediators that connect the setback runners to the wall materials, providing additional attachment points that make installation feasible even when runners are positioned setback from the floor slab end face.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Device complexity

If wall materials are directly attached to studs without back battens, then the device complexity is reduced, but the reliability of attachment deteriorates

Engineering Contradiction:

Improvedevice complexityVSAvoidreliability of attachment

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

Back battens act as intermediary attachment elements between the studs and wall materials. This additional component provides more secure attachment points and distributes loads more effectively, significantly improving the reliability of the connection.

Inventive Principle:

Principle #24Intermediary (Mediator)

4Adaptability or versatility

If runners extend beyond the floor slab end face to accommodate construction errors, then the adaptability to construction errors is improved, but the deformation under pressing forces worsens

Engineering Contradiction:

Improveadaptability to construction errorsVSAvoiddeformation under pressing forces

Core Design Contradiction:

Adaptability or versatilityVSShape

Solution Approach 1:

Back battens provide additional support and attachment points that prevent the runners from deforming under pressing forces, even when the runners extend beyond the floor slab end face to accommodate construction errors.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The addition of back battens creates a three-dimensional connection structure that distributes forces more effectively, preventing runner deformation while maintaining adaptability to floor slab construction variations.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

AI summary

To provide a connection structure between partition walls and a floor slab, and a method for constructing the connection structure, in which a wall material facing a vertical compartment is accurately attached to studs, without any deformation of runners and damage of the connection structure even if pressing forces are applied from the studs to the runners. A connection structure 100 configured to connect a first partition wall 30 and a second partition wall 40 to a floor slab 20 is provided. The first partition wall 30 and the second partition wall 40 are connected to the floor slab 20, and separate a vertical compartment 10 from an upper floor room 13 and a lower floor room 15 that are located adjacent to the vertical compartment 10 and above and below the floor slab 20. A lower runner 31 configured to accommodate a lower end of a first stud 32 is placed on the floor slab 20. An upper runner 33 configured to accommodate an upper end of a second stud 34 that forms the second partition wall 40 is placed below the floor slab 20. A first wall material 50 is fixed to the first stud 32 through a first back batten 80A and fixed to the second stud 32 through a second back batten 80B. The first wall material 50 extends from the first stud 32 to the second stud 24 in the vertical compartment 10.
