Solution Overview

Problem

The conventional beam reinforcement system in reinforced concrete structures faces challenges in adding main bars after stirrups are disposed, making the construction process inconvenient and time-consuming.

Innovation Solution

The stirrup module for beam reinforcement systems includes an outer stirrup set, an upper-opening stirrup module, and a lower-opening stirrup module, designed to facilitate the easy addition of main bars by overlapping openings and using rib structures for alignment and support.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional stirrups are disposed first and then main bars are added, then the stirrup structure can be established, but the construction process becomes inconvenient and time-consuming

Engineering Contradiction:

Improveconvenience of adding main barsVSAvoidconstruction time

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The stirrup modules are pre-assembled with openings positioned and oriented correctly before the main bars are installed. The upper-opening stirrup module and lower-opening stirrup module are prepared in advance with their respective openings facing appropriate directions, so that when main bars need to be added, they can be directly inserted through the pre-positioned openings without requiring time-consuming adjustments or repositioning of the stirrups.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The stirrup system is divided into separate modular units (upper-opening stirrup module and lower-opening stirrup module) that can be independently positioned and assembled. Each module has specific openings oriented in particular directions, allowing flexible assembly and easy access for inserting main bars without disrupting the overall stirrup structure.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If more main bars are added after stirrups are disposed, then the reinforcement can be enhanced, but the construction process becomes more complex

Engineering Contradiction:

Improveability to add main barsVSAvoidconstruction process complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The stirrup modules are pre-configured with openings positioned and oriented correctly before the main bars are installed. The upper-opening stirrup module and lower-opening stirrup module are prepared in advance with their respective openings facing appropriate directions, so that when main bars need to be added, they can be directly inserted through the pre-positioned openings without requiring time-consuming adjustments or repositioning of the stirrups.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The upper-opening stirrup module and lower-opening stirrup module are nested or overlapped with each other in a coordinated manner, with their openings aligned to provide access paths for main bars. This nested arrangement allows multiple main bars to be added through the same modular structure without increasing overall system complexity.

Inventive Principle:

Principle #7Nested doll (Nesting)

AI summary

A stirrup module includes an outer stirrup set, an upper-opening stirrup set having an upper opening and provided in an opening of the outer stirrup of the outer stirrup set, and a lower-opening stirrup set having a lower opening and provided in the opening of the outer stirrup of the outer stirrup set. Wherein the upper opening and the opening of the outer stirrup are oriented in the same direction, the lower opening and the upper opening are in opposite directions to each other. Wherein the upper-opening stirrup set has a first bottom of stirrup opposite to the upper opening, and the first bottom of stirrup corresponds to the position of the lower opening; the lower-opening stirrup set has a second bottom rib opposite to the lower opening, and the second bottom rib corresponds to the position of the upper opening.
