Construction Prop Assembly
Patent Number: US 10024069 Grant Date: 2018-07-17 Filing Date: 2014-11-14
Overview
This patent protects a practical, field-oriented improvement to grid shoring and beam-head prop assemblies that simplifies height adjustment while improving stability on concrete forming jobs. The design combines a screw-jack threaded shaft and a rotatable threaded collar in an upper drop-head assembly that selectively slides into a lower prop and fixed beam-head. The threaded collar locks against the shaft to set a precise, variable height, while removable drop-head end caps and bolted attachment plates allow rapid connection of beams and panels. Filed November 14, 2014 and granted July 17, 2018, the application reflects careful claim drafting to capture both the mechanical interface (threaded shaft, collar, prop lock) and system-level uses in grid-forming shoring systems. Inventors based in Katy, TX; Naples, FL; and Rochester, NY, assigned the rights to an applicant and assignee in Houston, TX.
The firm’s prosecution and drafting emphasized manufacturable details—clear threading interfaces, overlap safety considerations, and standard nut-and-bolt connections—helping secure robust protection for a commercially practical scaffolding element.
Key Features
- Variable-height adjustment via screw-jack shaft and rotatable threaded collar
- Removable drop-head with bolted attachment for easy beam release
- Prop lock and overlap guidance for enhanced on-site stability
- Modular grid shoring integration for panels and stringers
This patent strengthens product differentiation for contractors and manufacturers, boosting safety and efficiency in concrete formwork and broader civil construction applications.
Invention Details
Abstract: A construction beam head assembly comprising an improved forming system having one or more fixed beam-head prop assemblies each having an upper portion and a lower portion. The upper portion having a screw-jack threaded shaft assembly and a drop-head The lower portion comprising of a prop and a collar The screw-jack threaded shaft assembly having an external diameter and an external threading The screw-jack threaded shaft assembly attaches to the drop-head The upper portion selectively slides into the lower portion The collar having an internal threading and an internal diameter The internal threading of the collar rotateably attaches to the external threading of the screw-jack threaded shaft assembly of the upper portion. The upper portion and the lower portion adjustably attach to one another with the collar and the screw-jack threaded shaft assembly to provide a variable height of the prop assembly.
Background: CROSS-REFERENCE TO RELATED APPLICATIONS (1) This application claims benefit to provisional U.S. Patent Application No. 62/044,662, filed on 2014 Sep. 2. STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT (IF APPLICABLE) (1) Not applicable. REFERENCE TO SEQUENCE LISTING, A TABLE, OR A COMPUTER PROGRAM LISTING COMPACT DISC APPENDIX (IF APPLICABLE) (2) Not applicable. BACKGROUND OF THE INVENTION (3) This disclosure relates generally to an improved construction beam head assembly. Examples of construction props can be found in the following list of prior art references: U.S. Pat. No. 3,376,011 A, US 20070264076 A1, WO 2009009898 A1, and U.S. Pat. No. 7,584,932 B2. (4) None of the above inventions and patents, taken either singularly or in combination, is seen to describe the instant disclosure as claimed. Accordingly, an improved construction beam head assembly would be advantageous. SUMMARY OF THE INVENTION (5) Two system and a method of use are disclosed. (6) First, an improved grid shoring system comprising a one or more fixed beam-head prop assemblies supporting a one or more beams is disclosed. Each of said one or more fixed beam-head prop assemblies comprise an upper portion, a lower portion, a variable height, and a threaded collar. Said upper portion having a screw-jack threaded shaft assembly. Said screw-jack threaded shaft assembly comprises a threaded shaft having an external diameter and an external threading and an upper attachment plate having a plurality of fastening apertures. Said upper portion of said one or more fixed beam-head prop assemblies selectively slide into said lower portion of said one or more fixed beam-head prop assemblies. Said threaded collar comprises an internal threading and an internal diameter. Said internal threading of said threaded collar rotateably attaches to said external threading of said screw-jack threaded shaft assembly of said upper portion. Said lower portion comprises a lower central shaft having an internal diameter being larger than said external diameter of said threaded shaft. Said upper portion and said lower portion adjustably attach to one another by Selectively sliding said threaded shaft in an up and down direction through said lower central shaft of said lower portion. Vertically adjusting said threaded collar along said threaded shaft to select said variable height. Said upper portion comprises a first end cap seat. Said lower portion comprises a second end cap seat. Said upper portion having a drop-head. Said drop-head comprises a bottom plate having a plurality of fastening apertures. Said screw-jack threaded shaft assembly attaches to said drop-head by aligning said plurality of fastening apertures of said bottom plate of said drop-head with said plurality of fastening apertures of said upper attachment plate of said screw-jack threaded shaft assembly, and inserting and locking a one or more nut and bolt assemblies through said plurality of fastening apertures in said bottom plate and said upper attachment plate. Said first end cap seat is selectively attached to said drop-head of said upper portion. Said first end cap seat comprises a variable height. Adjusting said variable height of said first end cap seat comprises
