Abstract

Abstract A shoring system for building site excavating operations utilizing caisson holes drilled in spaced positions outside the building perimeter and receiving flanged pile elements with paired main piles disposed at regulated elevations and spacing and having vertically spaced support sockets adapted to receive fastener components for the support of horizontally disposed sheeting pieces that are placed progressively in inverted order to hold back loose materials as the foundation excavation is deepened. Intermediate pile elements are disposed between the main pile elements in aligned positions with respect thereto, and the flanges of such intermediate pile elements provide vertically elongated adjustment slots for the reception of a flange clamp receptacle that is adjustably positioned along the slot and held in such position by a spring clip. With such arrangement threaded or other fasteners to be received and held by the receptacles are extended through the slots provided by the main pile fastener components to hold the sheeting securely against the intermediate piles thereby providing additional shoring support. The flange clamp receptacles are in general disposed behind the flange of intermediate piles, and a shoulder or stop extends into such elongated slots to prevent rotary dislocations of the flange clamp receptacle.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 166 words
A shoring system for excavation operations at building sites where loose materials may be encountered comprising flanged main and intermediate piles disposed in intermixed space separated and aligned positions about the periphery of a site to be excavated, main receptacles disposed at spaced vertical positions along paired main piles, sheeting support fasteners applied to the receptacles of paired main piles in top to bottom order providing inwardly standing supports, sheeting members placed on the standing support fasteners of said main piles for extension between main pile elements and past intermediate piles with said standing support fasteners preserving a slot opening between adjacent sheeting members, said intermediate piles providing vertically elongated openings at spaced vertical positions, flange clamp receptacles adjustably received at said elongated openings for placement at positions of registration with respect to the slot openings between adjacent sheeting members, and auxiliary fasteners extending through said slot openings at the intermediate piles engagement with said flange clamp receptacles for the added support of said sheeting members.
Claim 2
Dependent Claim 166 words
A shoring system for excavation operations at building sites where loose materials may be encountered comprising flanged main and intermediate piles disposed in intermixed space separated and aligned positions about the periphery of a site to be excavated, main receptacles disposed at spaced vertical positions along paired main piles, sheeting support fasteners applied to the receptacles of paired main piles in top to bottom order providing inwardly standing supports, sheeting members placed on the standing support fasteners of said main piles for extension between main pile elements and past intermediate piles with said standing support fasteners preserving a slot opening between adjacent sheeting members, said intermediate piles providing vertically elongated openings at spaced vertical positions, flange clamp receptacles adjustably received at said elongated openings for placement at positions of registration with respect to the slot openings between adjacent sheeting members, and auxiliary fasteners extending through said slot openings at the intermediate piles engagement with said flange clamp receptacles for the added support of said sheeting members.
Claim 3
Dependent Claim 24 words
The system of claim 1 wherein said vertically elongated openings are spaced apart a vertical distance corresponding to the width of said sheeting members.
Claim 4
Dependent Claim 23 words
The system as set forth in claim 1 wherein said vertically elongated openings are provided in inwardly disposed flanges of said intermediate piles.
Claim 5
Dependent Claim 27 words
The system as set forth in claim 3 wherein said elongated openings are disposed in paired positions on opposite sides of the web of said intermediate piles.
Claim 6
Dependent Claim 24 words
The system as set forth in claim 4 wherein the said elongated openings at opposite sides of the pile web are at alternate elevations.
Claim 7
Dependent Claim 27 words
The system as set forth in claim 1 and further comprising a threaded element for said flange clamp receptacles adapted to receive and hold said auxiliary fasteners.
Claim 8
Dependent Claim 44 words
The system as set forth in claim 6 wherein said threaded element is disposed at the rear of the flanges for said intermediate piles and further comprising a shoulder element extended into said elongated openings to prevent turning movement of said flange clamp receptacle.
Claim 9
Dependent Claim 34 words
The system as set forth in claim 7 and further comprising a spring clip engaging the flanges of said intermediate piles to hold the flange clamp receptacles in adjusted positions along said elongated openings.
Claim 10
Dependent Claim 31 words
The system as set forth in claim 7 wherein the main receptacles provided along said main piles are threaded and wherein both said sheeting support fasteners and auxiliary fasteners are threaded.
Claim 11
Dependent Claim 20 words
The system as set forth in claim 9 wherein said sheeting support fasteners and auxiliary fasteners may be used interchangeably.
