Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional support devices for formwork beams lack adaptability for inclined structures, leading to installation difficulties and instability when constructing inclined floor slabs, and require screws or bolts for fixation, which is time-consuming.
Innovation Solution
A support device featuring a tubular upright with a T-shaped portion and a slideable supporting head with V-shaped recesses for accommodating beams, allowing adjustable inclination and secure locking without screws or bolts, utilizing elastic means for quick engagement with a prop.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional support devices with fixed recesses are used, then the structure is simple and easy to manufacture, but the adaptability to inclined formwork structures is poor
Solution Approach 1:
The supporting head is made slideable along the upright instead of being fixed, allowing it to move to different positions to accommodate various inclination angles. This dynamic positioning capability enables the device to adapt to inclined formwork while maintaining a relatively simple overall structure.
Solution Approach 2:
The recesses in the supporting head are designed with variable depth and shape characteristics that can accommodate beams at different inclination angles. By changing the geometric parameters of the recesses, the device achieves adaptability to inclined structures without requiring complex mechanical adjustments.
2Productivity
If screws or bolts are used to fix the supporting head to the prop, then the connection is secure and reliable, but the assembly and disassembly process becomes time-consuming
Solution Approach 1:
The screw or bolt fastening system is replaced with a direct insertion mechanism where the upright inserts into the prop and is retained by the supporting head's geometry. This substitution eliminates the need for threaded fasteners while maintaining secure connection through mechanical interlocking, significantly improving assembly speed.
Solution Approach 2:
The supporting head's recesses are designed to automatically engage and lock the upright in place during insertion, creating a self-securing connection. The gravitational force and geometric constraints work together to maintain reliable connection without requiring additional fastening operations, enabling quick assembly and disassembly.
3Ease of operation
If the recesses have fixed contours and dimensions, then the manufacturing is simple, but the ability to modulate inclination during mounting is lost
Solution Approach 1:
The supporting head is designed to slide along the upright, allowing workers to adjust its position vertically to achieve the desired inclination angle during mounting. This dynamic adjustment capability provides operational flexibility while the recesses themselves maintain simple, manufacturable geometries.
Solution Approach 2:
The system separates the inclination adjustment function into two independent elements: the vertical position of the supporting head along the upright, and the angular orientation of the beams in the recesses. This segmentation allows simple recess geometry while achieving inclination modulation through the slideable mechanism.

AI summary
A support device for supporting beams of formwork for floor slabs, which comprises an upright, the end of which can be fixed to a supporting prop that rests on the ground; a supporting head for at least one supporting beam of floor slab formwork, which is arranged coupled slideably along the upright, and elements of reversibly locking the supporting head on a preset position defined along the upright, the supporting head in turn comprises:two plates,at least two recesses, for guiding insertion and for containment for a resting portion of the corresponding supporting beam, each one of which is provided on a respective plate, each recess having a substantially flat bottom with a breadth such as to define a variable resting point for the supporting beam along the bottom as a function of the inclination of the supporting beam.
