Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing double-face superposed shear walls are underutilized in modular integrated buildings, leading to inefficiencies in production and cost, as they are often used as separate components rather than integrated modules, and face challenges in formwork-free operations and structural stability during assembly.
Innovation Solution
A construction method for modular shear walls based on double-face superposed shear walls, utilizing adjustment gaskets for level calibration, intelligent display-guided installation, and pre-embedded steel plates for connections, along with staggered annular stirrups and double steel plate pin joints to ensure stability and formwork-free assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If double-face superposed shear walls are used as separate components, then production capacity is increased, but integration efficiency in modular buildings is reduced
Solution Approach 1:
The patent merges multiple separate double-face superposed shear wall components into an integrated modular shear wall assembly. The connection structure combines steel plates, bolts, and welding to join wall panels, beams, and columns into a unified module that maintains the advantages of separate component production while achieving integrated building performance.
Solution Approach 2:
The patent segments the modular shear wall into standardized components (wall panels, beams, columns) that can be produced separately on existing production lines, then connected through standardized connection structures. This segmentation enables mass production of components while allowing flexible assembly into complete modular units.
2Productivity
If modular integrated buildings are constructed, then labor productivity is improved, but structural stability during assembly is reduced
Solution Approach 1:
The patent implements preliminary action by pre-assembling shear wall modules in controlled factory environments with precise positioning and temporary fixation. Connection components such as steel plates and bolts are pre-installed, and modules are pre-leveled using adjustment gaskets before final assembly on-site, ensuring structural stability is established before field construction begins.
Solution Approach 2:
The patent uses connection structures including steel plates, bolts, and welding as intermediaries between modular components. These connection elements serve as mediators that transfer and distribute loads throughout the assembled structure, maintaining structural stability while enabling modular construction methods.
3Manufacturing precision
If adjustment gaskets are used for level calibration, then installation precision is improved, but assembly complexity is increased
Solution Approach 1:
The patent implements self-service through self-leveling connection structures that automatically adjust to achieve proper alignment. The adjustment gaskets and connection details are designed to self-correct minor positioning errors, reducing the need for complex manual calibration procedures while maintaining high installation precision.
4Productivity
If formwork-free operations are implemented, then construction efficiency is improved, but connection reliability is reduced
Solution Approach 1:
The patent uses composite connection systems combining steel plates, bolts, and welding to achieve formwork-free assembly. This composite approach integrates multiple connection methods to ensure reliable load transfer between modular components without requiring traditional formwork, maintaining both construction efficiency and connection reliability.
