Modular Car Park Deck Modules With Recessed Post Housings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly of multi-storey above-ground car park modules is tedious and poses safety risks due to the large number of bolts required for definitive embedding, necessitating a solution for quicker and safer assembly.
Innovation Solution
The use of structural elements with housings and centering elements at the ends of modules and posts allows for stable support without additional operations, enabling easier handling and definitive embedding, and the incorporation of suspension means between modules to accommodate misalignment and provide a removable connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If multiple bolts are used to ensure definitive embedding between deck module and posts, then connection strength is improved, but assembly time and complexity increase
Solution Approach 1:
The connection system is segmented into two distinct phases: temporary support phase using lifting means, and definitive embedding phase using bolts. This segmentation allows the module to be safely positioned first, then permanently secured, separating the functions of positioning and permanent fixation to reduce overall assembly time while maintaining strength.
Solution Approach 2:
The lifting means provides preliminary support action before the final bolted connection is made. This preliminary action stabilizes the module in position, allowing operators to perform bolt installation without the module moving or creating unsafe conditions, thereby reducing the time needed for the embedding process.
2Reliability
If multiple bolts are installed to ensure definitive embedding, then connection reliability is improved, but operator safety risks increase
Solution Approach 1:
The lifting means performs preliminary support action that stabilizes the module before bolt installation begins. This preliminary stabilization creates a safe working condition where operators can install bolts without the module moving unexpectedly, eliminating the safety hazard of working on an unstable structure.
Solution Approach 2:
The lifting means acts as an intermediary element between the module and the final bolted connection. It provides temporary but sufficient support during the transition from positioning to permanent fixation, allowing operators to work safely while the system evolves from temporary to permanent connection.
3Stability of the object's composition
If lifting equipment is used to hold deck module during bolting, then module positioning is maintained, but operational complexity and safety hazards increase
Solution Approach 1:
The support function is segmented into two stages: lifting means for temporary positioning, and bolted connection for permanent fixation. This segmentation allows the complex lifting equipment to be used only briefly for positioning, after which the simpler bolted connection takes over, reducing overall operational complexity.
Solution Approach 2:
The lifting means performs the preliminary action of positioning the module, after which the bolted connection system takes over the support function. This preliminary positioning action simplifies subsequent operations because the module is already stable and in the correct position before bolt installation begins.

AI summary
The invention relates to a set of structural elements (1, 7) intended for being assembled to form an above-ground car park with at least one storey, said structural elements (1, 7) comprising so-called supported deck modules (1) and posts (7) for supporting same in assembled position. The set of structural elements (1, 7) is characterised in that the supported modules (1) comprise at least one recess (5) open at one end and capable of receiving the head of a post (7), and bearing means which are then capable of engaging with a respective post (7) by inserting the recesses (5) onto the respective heads so that the supported module (1) is supported in a stable manner.
