Parapet Panel Fastening Structure for Building Roofs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening structures for buildings with attics are inefficient due to high material and time requirements, dimensional inaccuracies, and increased risk of errors and accidents, while also occupying valuable space and failing to meet requirements for weather resistance, mechanical strength, and thermal insulation.
Innovation Solution
A fastening structure comprising a cement-bonded fine particle board parapet panel with a high degree of dimensional accuracy, connected to a substructure using angle components or fastening plates with mandrels and diagonal struts, which allows for easy assembly and stabilization, and includes a cover plate for water protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If traditional formwork blocks with thermal envelopes are used, then thermal insulation is improved, but material requirements and production time increase significantly
Solution Approach 1:
The parapet is divided into individual prefabricated panels that can be manufactured separately and assembled quickly on-site. Each panel is a complete unit with integrated thermal insulation, eliminating the need for on-site construction of formwork blocks and their thermal envelopes.
Solution Approach 2:
The thermal insulation is pre-integrated into the parapet panels during manufacturing rather than being added during construction. The panels are delivered ready-to-install with all necessary components, allowing immediate assembly without time-consuming on-site preparation.
2Temperature
If traditional formwork blocks are used, then thermal insulation is achieved, but dimensional accuracy deteriorates requiring correction work
Solution Approach 1:
The parapet is segmented into precisely manufactured panels produced in a controlled factory environment where dimensional accuracy can be ensured. This contrasts with on-site construction where achieving precise dimensions is difficult.
Solution Approach 2:
The manufacturing process is changed from on-site construction to controlled factory production, allowing for precise control of dimensional parameters. The panels are produced with high dimensional accuracy through industrial manufacturing processes.
3Strength
If conventional parapet construction is used, then structural requirements are met, but the enclosed usable area is reduced due to space requirements
Solution Approach 1:
The parapet panels utilize thin-walled box section constructions that provide the necessary structural strength while occupying minimal space. The efficient cross-sectional geometry maximizes strength-to-weight ratio and minimizes the space required.
4Object-affected harmful factors
If traditional attachment structures are used, then weather resistance is achieved, but the number of work steps increases leading to more error sources
Solution Approach 1:
Multiple functions are combined into single integrated components. The panels incorporate thermal insulation, weather protection, and structural functions in one element. Attachment systems are integrated into the panel design, reducing the number of separate work steps required.
Solution Approach 2:
The panels are designed as self-contained units with integrated attachment systems that simplify installation. The panels attach to each other and to the building structure through built-in connection elements, reducing the need for additional separate operations.
