Fireproof cabinet body structure and fireproof safety cabinet
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The use of gypsum boards in safety cabinets as a main body supporting frame is hindered by their insufficient load-bearing capacity, which affects the strength and fireproof/safety performance of the cabinet, and the higher production costs of gypsum boards with greater load-bearing capacity make mass production economically challenging.
Innovation Solution
A fireproof cabinet body structure is designed with a keel frame that has greater rigidity than the gypsum board, where the gypsum board is fixed to the outer vertical surface of the keel frame, and support legs penetrate through the gypsum board to be fixedly connected with the keel frame, allowing the keel frame to bear the load and the gypsum board to provide fireproofing without bearing weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If gypsum board is used as the main body supporting frame of the safety cabinet, then the fireproof performance is improved, but the load-bearing capacity and structural strength deteriorate
Solution Approach 1:
The patent uses a composite structure combining gypsum board and metal keel frame. The gypsum board provides fireproof protection while the metal keel frame provides structural support and load-bearing capacity. This composite approach allows both materials to contribute their respective strengths without compromising either fireproof performance or structural strength.
2Strength
If gypsum board with higher load-bearing capacity is used, then the structural strength is improved, but the production cost increases
Solution Approach 1:
The patent segments the functional requirements by dividing the cabinet body into two distinct components: the gypsum board for fireproofing and the metal keel frame for structural support. This segmentation allows each component to be optimized independently, using standard, cost-effective gypsum board without needing expensive high-strength variants.
Solution Approach 2:
The metal keel frame acts as an intermediary structural element that bears the load, allowing the gypsum board to focus solely on fireproofing functions. This intermediary structure enables the use of economical gypsum board while maintaining overall structural strength.
3Reliability
If gypsum board is used as the main body supporting frame, then the fireproof performance is improved, but the structural stability deteriorates
Solution Approach 1:
The composite structure of gypsum board combined with metal keel frame ensures both fireproof performance and structural stability. The metal keel frame provides a rigid, stable framework that maintains the cabinet's structural integrity, while the gypsum board adheres to this stable framework to provide fireproof protection.
