Demountable Modular Parking Lot Structural Design

Solution Overview

Problem

Existing demountable modular parking lot structures are complex and costly due to their intricate structural elements, and they often require additional beams, making them difficult to construct and assemble, especially when multiple levels are needed.

Innovation Solution

A simplified modular parking lot design using steel edge beams, junction elements, and one-piece fixed-length vertical support elements, which reduces complexity and construction costs, and allows for easy assembly and adjustment, enabling multiple levels with fewer beams and a more straightforward assembly process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If traditional modular parking lot structures are used with multiple beams and complex vertical support elements, then structural integrity is maintained, but device complexity and construction costs increase significantly

Engineering Contradiction:
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The patent removes the secondary steel beam from the traditional five-beam configuration, retaining only the four perimetral edge beams. This extraction of the intermediate beam simplifies the structure while the floor slab itself provides the necessary span reduction, eliminating the need for the secondary beam and reducing overall structural complexity

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent integrates the floor slab to perform multiple functions: it serves as both the parking surface and as a structural element that spans between edge beams, replacing the need for separate secondary beams. This merging of functions reduces the number of structural components while maintaining integrity

Inventive Principle:
Principle #5Merging (Combining)

2Stability of the object's composition

If traditional vertical support elements with hinge mechanisms are used, then structural stability is achieved, but ease of manufacture and assembly are reduced due to complex assembly requirements

Engineering Contradiction:
Core Design Contradiction:
Stability of the object's compositionVSEase of manufacture

Solution Approach 1:

The vertical support element is designed as a single integrated piece combining the support column and base structure, eliminating the need for separate hinge mechanisms, spherical caps, and threaded connections. This unified design maintains structural stability while dramatically simplifying manufacturing and assembly operations

Inventive Principle:
Principle #5Merging (Combining)

3Manufacturing precision

If traditional modular units with five beams are used, then floor slab span is reduced, but quantity of substance and construction costs increase

Engineering Contradiction:
Core Design Contradiction:
Manufacturing precisionVSQuantity of substance

Solution Approach 1:

The patent extracts and removes the secondary steel beam from the traditional configuration, reducing the beam quantity from five to four per modular unit. The floor slab is designed to span directly between the four edge beams, eliminating the need for the intermediate secondary beam while maintaining acceptable span ratios

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent changes the structural approach by allowing the floor slab to assume greater spanning capability, modifying the span parameters to work with only the four perimetral beams rather than requiring the additional secondary beam for span reduction

Inventive Principle:
Principle #35Parameter changes

AI summary

The parking lot is of the demountable and remountable modular type for motor vehicles, is composed of at least one upper storey in addition to the ground floor and comprises, in addition to one or more access ramps to the upper storeys, a determined number of modular structural units (10; 10NL, 10L) and adequate bracing elements (43, 44). Each modular structural unit (10; 10NL, 10L) comprises: a square or rectangular deck including steel beams (12, 14, 14L) which carry a single floor slab (16) or several side by side floor slabs (16A, 16B, 16L), the floor slab (16) or floor slabs (16A, 16B, 16L) being formed using sheet steel; four junction elements (30), also of steel, on which the deck rests at its four corners; four steel vertical support elements (18) at the top of which a junction element (30) is provided; and four steel bases (36), each base (36) comprising a baseplate (38) from which a tubular collar (40) extends coaxially upwards to receive fairly loosely the lower end of the relative vertical support element (18). The deck comprises only two steel edge beams (12) parallel to each other. Each vertical support element (18) is formed in one piece of fixed length, the lower end of which is directly insertable loosely into the tubular collar (40) of the relative base (36).
