In-Deck Conduit Support Structure for Stable Concrete Deck Wiring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional in-deck conduits for concrete decks are vulnerable to damage and misplacement due to lack of support before the concrete sets, and they often require complex alignment and retention mechanisms for wiring and tubing.
Innovation Solution
The design includes laterally extending support legs and internal passages with improved configurations, such as curved profiles and angled transitions, along with external locking arms to enhance stability and ease of installation, and secure retention of wiring and tubing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional in-deck conduits are installed without additional support structures, then the installation process is simple, but the conduits are vulnerable to damage and misplacement due to lack of support before concrete sets
Solution Approach 1:
The conduit is pre-formed with an integrated support leg structure that extends laterally from the body. These legs are positioned to rest on the formwork before concrete pouring, providing preliminary support and preventing displacement during the concrete setting process. The support legs are built into the conduit body during manufacturing, eliminating the need for separate support installations.
2Ease of operation
If conventional conduits use simple opening designs, then the manufacturing is easier, but they require complex alignment and retention mechanisms for wiring and tubing
Solution Approach 1:
The conduit body includes a curved internal passage that transitions from a first opening at the deck end to a second opening at the base end. The curved profile naturally guides wiring and tubing through the conduit, eliminating the need for complex alignment mechanisms. The smooth curvature reduces friction and facilitates easy routing of electrical components.
3Quantity of substance
If the conduit body is made compact, then the material usage is reduced, but the internal passage may be difficult to access and wire
Solution Approach 1:
The conduit utilizes a three-dimensional curved passage design that efficiently uses internal space while maintaining adequate cross-sectional area for wiring. The passage extends through the conduit body in a curved path from the first opening to the second opening, providing sufficient room for wiring operations without increasing the overall external dimensions of the conduit body.

AI summary
An in-deck conduit for installation on a form for a concrete deck can provide a passage for wiring or other components within the concrete deck. The in-deck conduit can have a body with a base end, a deck end, and an internal passage extending from the base end to the deck end. One or more support legs can extend from the deck end of the body laterally relative to the passage to support the body on the form.
