Abstract
Description
- The invention relates generally to shoring apparatus used in forming concrete structures and, more specifically, to an extruded post having a profile which makes it adaptable for use in a variety of shoring apparatus.
- Concrete forming apparatus is in wide use in the construction of buildings, bridges, and other concrete structures. The formwork against which the concrete is formed is often held in place by shoring apparatus. In creating shoring apparatus having the desired configuration, it is beneficial to be able to interconnect various components of the shoring apparatus in a wide variety of adjusted positions and to be able to quickly and easily connect, disconnect, and adjust the positions of the components. Further, it is advantageous to have the ability to interconnect the various components of the shoring apparatus in a wide variety of configurations without unduly multiplying the number of distinct components that are required to assemble the shoring apparatus of the desired diversity.
- One of the important components of shoring apparatus having the desired flexibility and diversity of configuration is a shoring post which has a profile that includes channels or the like which may be engaged by clamps or other engagement apparatus associated with other shoring apparatus components. An engagement apparatus of this type is described in United States Patent No. 5,713, 687, which also shows but does not describe a shoring post which presents a profile that is adapted for clamping engagement by the coupling which is the subject of the patent.
- Another clamp assembly is described in United States Patent Applications Serial No. 09/524,480, entitled "Clamp for Interconnecting Components of Shoring Apparatus" filed of even date herewith.
- In addition to having a design which is adaptable to the wide variety of configurations required of the shoring apparatus, it is also advantageous that the shoring posts be strong yet light in weight so they are easily transportable and positionable by workers in assembling, moving, and disassembling the shoring apparatus. Another demand is that the shoring posts be inexpensive to manufacture yet durable so that they are economical to use.
- According to the invention in a broad aspect there is provided a clamp as defined in Claim 1. Optional features of the invention are defined in the claims dependent from Claim 1. In a preferred embodiment the invention consists of an extrusion having a particular profile useful as shoring posts in the assembly of shoring apparatus. The extrusion is of a generally hollow, tubular shape and includes at least a pair of mirrored projections that extend from the outer periphery of the extrusion over a substantial length of the extrusion. The mirrored projections form a central channel that is of a generally C-shape in transverse cross-section. The outer periphery of the extrusion between the projections is substantially planar and forms the web of the C-shaped channel. A substantially planar section of each of the projections extends generally radially at either side of the web portion. An in-turned lip of each of the projections completes the generally C-shaped channel of the extrusion.
- The projections also form a pair of opposing clamping channels on the side of each projection outside of the C-shaped channel formed between the projections. The clamping channel has three sections, a base section which is the outer circumferential periphery of the extrusion in the area of the base of the projection, a primary engagement surface that slopes radially outwardly and at the same time generally inwardly toward the C-shaped channel at the base of the projection adjacent the base portion, and a retaining lip which extends from said engagement surface generally outwardly away from the interior C-shaped channel.
- The C-shaped channel is adapted to receive the head of a bolt that is commonly used in the construction of the shoring apparatus so that the bolt is constrained to move within the channel along a line parallel to the longitudinal axis of the shoring post and which can be releasably secured at any desired position by a suitable nut. The C-shaped channel further is adapted to receive the head of a lock bolt which may be introduced into the channel when in its unlocked orientation but, once positioned, can be pivoted to its locked position wherein it securely engages the sides of the C-shaped channel whereupon it is locked into place. The clamping channels are adapted to receive the jaws of a clamp that is used for interconnecting other components of the shoring apparatus at adjusted positions along the length of the shoring post. In the preferred embodiment of the invention, the extrusion is formed with eight of the projections arranged in four pairs that are symmetrically placed about the circumferential periphery of the extrusion.
- An advantage of the invention is to provide an extruded shoring post that is adapted to serve as a means of attachment of various components of a shoring apparatus.
- Another advantage of the invention is to provide an extruded shoring post having a profile which is suitable for engagement by both clamping-type connectors as well as bolt-type connectors.
- A further advantage of the invention is to provide an extruded shoring post that is strong, lightweight, durable, and economical to manufacture.
- These and other advantages of the invention will be made apparent to those skilled in the art upon a review and understanding of this specification, the associated drawings, and the appended claims.
- There now follows a description of preferred embodiments of the invention, by way of non-limiting example, with reference being made to the accompanying drawings in which:

projections central channel 42 that is of a generally C-shape in transverse cross section. Thecentral channel 42 is sized to accept for longitudinal sliding movement therein the head of a bolt 44 (Fig. 6) such as that which is commonly used in the assembly of shoring apparatus. The head of thebolt 44 is inserted into thecentral channel 42 at the opening thereto that is at either end of theshoring post 16. Thebolt 44 may then be slid to any desired position within thecentral channel 42 and then releasably secured into place by the attachment of a nut (not shown) in the conventional manner. Alternatively, the head of a locking bolt (not shown) may be aligned with the opening between the in-turned flanges of thecentral channel 42 and then pivoted to its locked position wherein it engages the sidewalls of thecentral channel 42 in the usual fashion. - The details of the profile of
projection 30 will be described, it being understood that the profile ofprojection 32 is identical thereto but reflected about the radial plane that passes midway between the two projections. Primes will be used to indicate the corresponding elements of the profile ofprojection 32 where needed for clarity in this description. When used in describing the profiles of theprojection 30, the term "inward" will refer to the direction toward the plane of symmetry shared with theprojection 32 while the term "outward" will refer to the direction away from the plane of symmetry. - The
projection 30 includes a substantially flatcentral channel surface 50 that is disposed parallel to the line of symmetry and extends from a base orweb portion 52 formed in the outer periphery of the extrusion.
