![]() ![]() An internal reinforcement framework is affixed to the plate and embedded within the concrete block.the plate has a hole aligned with the central aperture.a plate is disposed at the top end of the concrete block.an adjustable concrete pier is made of a concrete block having a central aperture extending from a top surface of the block to a bottom surface of the block.the design of the rod and nut permits greater vertical adjustability than the prior-art design.replaceable) unlike the prior-art design which permanently embeds the rod in the concrete. the threaded rod (with its upper support member) is thus removable (i.e.the threaded rod has a nut larger than the central aperture so that the nut abuts the plate surrounding the aperture.the novel adjustable concrete pier has a central aperture into which a threaded rod (having an upper support member) may be inserted.Accordingly, this pier is a adjustable structural pier. This adjustable concrete pier incorporates an internal reinforcement framework to dramatically strengthen the pier.the present invention provides a novel adjustable concrete pier that overcomes the deficiencies identified above with respect to the prior art.There is no ability to replace the threaded rod. a third design limitation of this prior-art pier block is that, since the threaded rod is embedded permanently in the concrete pier block, the pier block can only be used with that particular threaded rod.the range of adjustability of this prior-art adjustable pier block is limited as the top coupling can only be safely raised a certain amount before the coupling and threaded rod become undone or loose.this design is vulnerable to failure, particularly under impact loading.This adjustable concrete pier has a threaded rod embedded into the concrete footing (concrete block).This adjustable pier block can be also be re-adjusted if the ground has settled over time.This adjustable pier block is height-adjustable so that a deck, porch, structural beam, etc.5,561,950 discloses an adjustable concrete pier that attempts to address this problem. a further problem is that the ground may move or settle over time, for example due to freezing and thawing.a longstanding problem with concrete piers is that levelling is difficult during construction.Concrete piers are commonly used to support structures such as dwellings, porches, decks, etc. ![]() the present invention relates generally to concrete piers and, more particularly, to adjustable concrete piers.E02D27/32- Foundations for special purposes.E02D27/00- Foundations as substructures.E02D- FOUNDATIONS EXCAVATIONS EMBANKMENTS UNDERGROUND OR UNDERWATER STRUCTURES.E02- HYDRAULIC ENGINEERING FOUNDATIONS SOIL SHIFTING.Assignors: LAURIN, LUC Status Expired - Fee Related legal-status Critical Current Adjusted expiration legal-status Critical Links ASSIGNOR(S) HEREBY CONFIRMS THE ALL RIGHT TITLE AND INTEREST.
