The present disclosure relates to a construction apparatus, and, in particular, relates to an anchor apparatus adapted to function as a safety grip for construction personnel and/or for supporting construction equipment such as ductwork, electrical cables, plumbing etc. within a construction-site.
Construction sites require grip or strap devices to ensure the safety of construction personnel operating at the site. A conventional grip device may include a strap which is secured to a wall, beam or the like through a fastener and placed at various locations within the construction site such that upon moving through the site, the construction personnel may engage one of the devices at one or more select locations.
However, conventional grip devices present a number of obstacles, which detract from their overall usefulness. First, application of the grip device requires additional tasks to secure the device to the structural element. Secondly, the integrity of the grip device is dependent on the fastener utilized and its application, which, in many instances, is insufficient to adequately support construction personnel. Furthermore, current grip devices only have a single utility as a safety grip and cannot be used in conjunction with other tasks to be performed at the construction site.
One anchor apparatus which addresses many of these issues of conventional grip devices is disclosed in commonly assigned U.S. Patent Publication No. 20180058062 to Mayer et., the entire contents of which are incorporated by reference herein.
Accordingly, the present invention is directed to a construction anchor apparatus having utility as a safety grip for engagement by construction personnel, and, in addition, a support apparatus for supporting and/or holding construction equipment including ductwork, electrical cables, plumbing etc. The anchor apparatus is used in conjunction with a reinforcement member such as, e.g., rebar, applied in concrete support walls, floors, ceilings or other structural elements at a construction site.
In one embodiment, a construction anchor apparatus includes a main module having first and second wall segments and defining a central longitudinal axis, a first movable support operatively coupled to the first wall segment of the main module and having a first tube segment defining an opening therethrough and a second movable support operatively coupled to the second wall segment of the main module. The second movable support defines an opening configured for reception of the first tube segment of the first movable support to couple the first and second movable supports. The openings of the first and second movable supports are dimensioned for reception and passage of a reinforcement member, e.g., rebar. Each of the first and second movable supports is adapted for longitudinal movement relative to respective first and second wall segments of the main module to permit corresponding movement of the rebar within the main module.
The second movable support may include a second tube segment, which defines the opening for reception of the first tube segment of the first movable support. The first and second movable supports may be configured for movement in first and second longitudinal directions with respect to the longitudinal axis. At least one of the first and second movable supports is biased in a first longitudinal direction with respect to the longitudinal axis. A resilient member may be mounted within the main module, and is operatively engageable with the at least one of the first or second movable supports. In an embodiment, the resilient member is a spring positioned to engage the first tube segment of the first movable support.
An end cap may be mountable to the main module, and supports the spring. The end cap may include spring supports which are correspondingly dimensioned to at least partially accommodate the spring member to facilitate alignment with the first tube segment of the first movable support.
In embodiments, the first and second wall segments of the main module include respective first and second module mounts. The first movable support is coupled to the first module mount and is configured for reciprocal longitudinal movement relative to the first module mount, and the second movable support is coupled to the second module mount and is configured for reciprocal longitudinal movement relative to the second module mount. The first and second module mounts each define elongated openings in alignment with the openings of the first and second movable supports to permit traversing longitudinal movement of the reinforcement member.
The openings of the first and second movable supports are each configured to permit passage of a reinforcement member therethrough. At least one of the first or second module mounts includes a guide depending outwardly therefrom with respect to the central longitudinal axis. The guide is configured to facilitate alignment of the reinforcement member with the opening of the respective first or second movable support. In embodiments, each of the first and second module mounts includes a guide depending outwardly therefrom. The guides also may function as stops or limits positioned to engage the rebar to contain movement of the rebar within the main module.
In another exemplary embodiment, a construction anchor apparatus includes a main module having first and second wall segments and defining a central longitudinal axis, with the first and second wall segments each defining respective first and second elongated openings, a first movable support operatively coupled to the first wall segment of the main module and having a first tube segment defining an opening therethrough for reception of a reinforcement member, a second movable support operatively coupled to the second wall segment of the main module and defining an opening configured for reception of the first tube segment of the first movable support to couple the first and second movable supports. The openings of the first and second movable supports are configured for reception of the reinforcement member. Each of the first and second movable supports are configured for longitudinal movement relative to respective first and second wall segments of the main module to permit longitudinal traversing movement of the reinforcement member within the main module while the reinforcement member traverses the elongated openings of the first and second wall segments. A spring member is operatively couplable to one of the first and second movable supports to bias the first and second movable supports in a first longitudinal direction.
In another exemplary embodiment, a method includes positioning an anchor apparatus at a predetermined location within a construction site, securing a main module of the anchor apparatus at the predetermined location, coupling first and second movable supports to the main module and to each other with each of the first and second movable supports having openings therethrough, passing a reinforcement member through the openings in the first and second movable supports and through the main module and permitting the first and second movable supports to move in a longitudinal direction to permit corresponding movement of the reinforcement member relative to the main module. A support assembly may be secured to the reinforcement member.
Other advantages of the construction anchor apparatus will be appreciated from the following description.

The use of the anchor apparatus 100 at a construction site will now be described. A plurality of anchor apparatuses 100 are positioned at various predetermined locations within the construction site to eventually serve as safety grips for construction personnel or supports for construction equipment. In embodiments, these locations are coincident with walls, ceilings, floors, columns or other structural elements. Each anchor apparatus 100 may be temporarily secured at the select position with tie rods or the like. In the alternative, with the end cap 170 of

With a plurality of anchor apparatuses 100 and associated support mechanisms 2000 coupled thereto in select positions about the construction site, construction personnel may traverse the construction site, through engagement with the support assemblies 2000. Alternatively, the support assemblies 2000 may be used to support construction material, lines, ductwork, wires etc. It is to be appreciated that the movability of the first and second movable supports 106, 108 relative to the main module 102 may also accommodate shifting movement of construction material. For example, if the construction site is subjected to an event either natural or man-made, e.g., an earthquake or the like, which may potentially displace the construction material, the first and second movable supports 106, 108 will traverse their respective module mounts 120, 122 to accommodate any displacing movement, either lateral, vertical or horizontal, of the construction material thereby preserving the integrity of the unit.
Once it is determined the anchor apparatuses 100 are no longer needed, e.g., upon completion of a construction phase, the support assemblies 2000 may be removed from the rebar 1000 and their respective anchor apparatuses 100. In embodiments, the main module 102 of each anchor apparatus 100 may be filled with concrete to close the internal chambers 118. Thus, the anchor apparatuses 100 may be permanently embedded in the structural element, e.g., including the walls, columns, floors of the building, and do not require removal. In other embodiments, the main module 102 is left unfilled.
The end cap 524 includes an outer wall 526 for reception within the lower end 528 of the main module 502. Cooperating ribs 530 on the end cap 524 may be received within correspondingly dimensioned grooves (not shown) adjacent the module mounts 504, 506 of the main module 502 to assist in aligning the end cap 524 with the main module 502 during insertion and assembly. The end cap 524 includes opposed flange segments 532 for securing the end cap 524 and the main module 502 to framing of the structure.
In this embodiment, the main module 502 is devoid of a spring to bias the first and second movable supports 510, 512 toward the top 534 of the main module 502 displaced from the end cap 524. The main module 502 also includes guides 536 adjacent the top of the elongated slots 508 to assist in aligning the reinforcement member 1000 with the opening 538 of the first tubular segment 518 of the first movable support 510 and the opening 522 of the second tubular segment 520 of the second movable support 512, and/or restrict movement of the reinforcement member 1000 within the elongated openings 508 of the first and second module mounts 504, 506. In other respects, the anchor apparatus 500 is utilized in a similar manner to the anchor apparatus 100 of
