Definitions

  • This invention relates generally to concrete forming structures. More particularly, the present invention relates to apparatus for interlocking forms utilized in molding concrete footings and curbing.
  • Reusable, multi-paneled forms are usually used for molding concrete structures such as footings. Such forms generally require additional elements with which to interlock the opposed panels such that the sides of the form are rigidly locked at a predetermined distance which defines the width of the footing.
  • Conventional locking devices commonly require insertion of portions of a rod through complementary openings in the panels. Use of these locking devices requires aligning the complementary openings, a procedure which can be time consuming. Further, the rod generally have a fixed length and therefore provide no flexibility with respect to setting the width of the footing.
  • the invention in a preferred form is a locking device for use with a concrete framing structure having a plurality of frame panels which form opposed first and second sides.
  • the locking device includes first and second locking halves, each having a mounting member for rigidly holding one of the frame panels of the first and second sides, respectively, of the concrete forming structure.
  • Each locking half also has a horizontal, U-shaped extension member mounted to the mounting member.
  • Each extension member has a base segment connecting oppositely disposed leg segments, the base and leg segments forming a channel.
  • the extension member of the first locking half is receivable within the second extension member channel.
  • a clamp assembly includes a U-shaped clamp member having first and second arm segments extending downwardly from a saddle segment. Each of the arm segments has an opening for receiving the extension members.
  • a threaded shaft of a bolt is threadably engaged in a threaded orifice in the clamp member saddle segment.
  • the bolt tip engages an upper surface of the second extension member base segment.
  • the first mounting member is locked at a predetermined distance from the second mounting member by torquing the clamp assembly bolt, whereby a bottom surface of each clamp member leg segment opening engages a bottom edge of each leg segment of the first extension member to clamp the first extension member to the second extension member.
  • the height of the leg segments of the first extension member are substantially equal to the height of the leg segments of the second extension member. Accordingly, the leg segments of the first extension member extend below the leg segments of the second extension member when the first extension member is disposed within the second extension member channel.
  • a support bracket for suspending an object between the frame panels of the concrete framing structure may be mounted on one of the extension members.
  • bracket includes a bracket member forming a channel having an opening, with the extension member being inserted through the opening into the channel.
  • a bolt removably mounts a clamp member to the bracket member, such that the clamp member closes at least a portion of the opening to retain the extension member in the channel.
  • the bracket member includes a U-shaped engagement section and a mounting segment extending substantially horizontally from the engagement section.
  • the mounting segment has at least one opening for receiving a wire or a string mounted to an end of the object.
  • the engagement section of the bracket member includes first and second side portions and a top portion connecting the first and second side portions, the side portions and the top portion form the channel for receiving the extension member.
  • a threaded nut mounted to the inner surface of the second side portion is coaxial with the opening. The nut is threadably engageable with a threaded shaft of the bolt.
  • the clamp member is C-shaped including a top portion, a bottom portion and a side portion connecting the top and bottom portions. T he top and bottom portions and the side portion form a channel for receiving the second side portion of the bracket member engagement section.

Cet élément de blocage comporte des premier et second demi-éléments de blocage, présentant chacun un élément de fixation destiné à maintenir, de manière rigide, un des panneaux de coffrage des premier et second côtés, respectivement, de la structure de coffrage à béton. Chaque demi-élément de blocage présente également un élément d'extension horizontal en U fixé à l'élément de fixation, l'élément d'extension du premier demi-élément de blocage étant placé à l'intérieur du canal du second élément d'extension. Un ensemble de serrage comprend un élément de serrage en U pourvu de premier et second segments de bras s'étendant vers le bas à partir d'un segment d'appui. Chaque segment de bras présente une ouverture destinée à recevoir les éléments d'extension. Un boulon présentant une tige filetée engagée dans un trou taraudé, pratiqué dans le segment d'appui de l'élément de serrage, est serré de manière à bloquer le premier élément de fixation à une distance prédéterminée du second élément de fixation.
