Solution Overview

Problem

Existing scaffolding construction methods require cranes or person lifts for mounting and dismounting, posing safety risks and increasing costs, as personnel often need to climb unfinished frameworks.

Innovation Solution

A scaffolding construction system with height-adjustable bracket elements allows for preassembly near the ground, eliminating the need for lifting devices and climbing, with vertical support elements tensioned between the ground and eave or roof, and the working area entity lifted to desired heights using motor-driven winches.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If cranes or person lifts are used for mounting scaffolding, then the scaffolding can be assembled at height, but the mounting costs increase and equipment complexity increases

Engineering Contradiction:
Improvescaffolding assembly at heightVSAvoidmounting equipment
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The bracket element is pre-assembled on the ground at a lower level with all necessary connections and components prepared beforehand. This preliminary assembly eliminates the need for complex lifting equipment during actual installation, as the pre-assembled unit can be installed as a complete module rather than assembling individual components at height.

Inventive Principle:
Principle #10Preliminary action

2Device complexity

If personnel climb on unfinished frameworks to mount them, then equipment costs are reduced, but occupational safety risks increase

Engineering Contradiction:
Improvemounting equipmentVSAvoidoccupational safety
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

By completing the assembly of the bracket element and its connections to the vertical support element on the ground before installation, personnel work in a safe, stable environment rather than climbing on incomplete structures. The pre-assembled module is then installed as a complete unit, eliminating the safety risks associated with working at height during assembly.

Inventive Principle:
Principle #10Preliminary action

3Stability of the object's composition

If the bracket element is fixed at a single elevation, then structural stability is improved, but adaptability to different working heights is reduced

Engineering Contradiction:
Improvebracket element stabilityVSAvoidworking height adjustment
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The bracket element incorporates a movable connection to the vertical support element that allows elevation adjustment along the support element's length. This dynamic positioning capability enables the bracket to be relocated to different heights while maintaining structural stability at each position, providing both adaptability and stability.

Inventive Principle:
Principle #15Dynamics

4Device complexity

If scaffolding components are assembled at ground level and then lifted, then mounting costs are reduced, but lifting capability is required

Engineering Contradiction:
Improvemounting equipmentVSAvoidground-level assembly
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The bracket element is completely assembled on the ground including all connections to the vertical support element, horizontal part, and diagonal support member. This ground-level assembly reduces mounting costs by eliminating the need for complex equipment, and the completed module can be installed as a single unit requiring minimal lifting capability.

Inventive Principle:
Principle #10Preliminary action

AI summary

The invention relates to a framework support structure and a framework construction and a method for mounting a framework construction. The framework support structure comprises a vertical support element (110) and a bracket element (100) movably connectable to the vertical support element and movable in the direction of its vertical axis. The vertical support element (110) is adapted to be tensioned between the supporting surface (80) and an eave or roof structure (60), wherein the adjustable leg (115) at the lower end of the vertical support element and the upper end (111) form the sole points of support of the framework construction after tensioning, or to be attached with fastening means at least from its upper part to a wall (70) and/or roof structure (60) such that the major part of the length of the vertical support element hangs in a vertical position. The elevation of the bracket element (100) can be adjusted by moving the bracket element (100) in the direction of the longitudinal axis of the vertical support element (110) and the bracket element (100) is removably attachable to various elevations. The framework construction comprises several framework support structures placed adjacent to one another which are connected by means of the working platform (50), handrail (141) and intermediate rail (142) removably attachable to the bracket elements (100) and/or handrail posts (140). The working area entity is preassembled and after the assembly lifted up as a whole to the desired working height by moving the bracket elements (100) along the vertical support elements (110).
