Composite Wall Fixing Devices for Faster Insulation Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional construction methods for composite walls are labor-intensive and time-consuming due to multiple measuring and drilling steps required for attaching thermal insulation and cover plates.
Innovation Solution
The use of fixing devices composed of a main rod, housing, blocking plate, and positioning unit to attach thermal insulation layers to formworks, allowing for simplified installation and reduced drilling, thereby saving labor and time.

Engineering Contradiction Analysis
1Productivity
If conventional construction methods are used with multiple measuring and drilling steps, then the composite wall can be constructed, but the construction process becomes labor-intensive and time-consuming
Solution Approach 1:
The formwork is designed with pre-positioned fixing devices that are installed before concrete pouring. These fixing devices include positioning structures that automatically align with predetermined locations on the wall, eliminating the need for subsequent measuring and drilling operations. The thermal insulation plates are also pre-equipped with connecting structures that match the fixing devices, enabling direct attachment after formwork removal.
Solution Approach 2:
The fixing devices incorporate self-positioning mechanisms that automatically locate and secure themselves at correct positions during concrete pouring. The devices include self-aligning features that ensure proper positioning without requiring manual measurement or adjustment, and the thermal insulation plates have self-connecting structures that automatically engage with the fixing devices.
2Reliability
If multiple drilling steps are performed for installing thermal insulation material and cover plates, then the composite wall structure is achieved, but labor intensity increases significantly
Solution Approach 1:
The fixing devices integrate multiple functions into a single component: they serve as both the anchoring mechanism embedded in the concrete and the mounting structure for thermal insulation plates. The connecting structures combine the fastening and positioning functions, eliminating the need for separate drilling and fastening operations for each layer.
Solution Approach 2:
The fixing devices are designed as universal components that can secure both thermal insulation plates and cover plates through standardized connecting structures. This multi-functional design allows the same fixing device to support different layers and components throughout the construction process, reducing the variety of specialized fasteners needed.

AI summary
A construction method includes steps of: using a plurality of fixing devices (4, 4", 4‴) to extend through a thermal insulation layer (2) and an outer formwork (3), wherein, each of the fixing devices (4, 4", 4‴) projects out of the thermal insulation layer (2) and the outer formwork (3); respectively disposing an inner formwork (5) and the outer formwork (3) to which the thermal insulation layer (2) is attached at two sides of a support frame layer (1), wherein, the thermal insulation layer (2) faces the support frame layer (1); pouring a to-be-cured material into the support frame layer (1); removing the inner formwork (5) and the outer formwork (3); respectively disposing a plurality of external brackets (6) on portions of the fixing devices (4, 4", 4‴) that project out; and installing a plurality of outer cover plates (7) on the external brackets (6).
