Abstract
A subfloor and subfloor anchoring system are disclosed, including a subfloor anchor adhesively attached to a slab. The subfloor anchor can include an anchor base and an anchor pin, with the anchor base adhesively attached to the slab, and the anchor pin attached to the anchor base and advanceable towards the anchor base. The anchor pin contacts an upper surface of a subfloor component and to anchor the subfloor to the slab.
Claims19
A subfloor configured to support flooring with respect to a slab, the subfloor comprising:
- a resilient layer positionable over the slab;
- a frame carried by the resilient layer and suspendable above the slab by the resilient layer;
- openings in the frame, each opening comprising a slot extending from the aperture, the slot extending from a top surface to a bottom surface of the frame, the slot having a substantially continuous cross section extending from the top surface to the bottom surface;
- and
- adhesive anchors located in the openings, each adhesive anchor comprising:
- an anchor base with a bottom surface and an adhesive applied to the bottom surface to adhere the anchor base to the slab;
- an anchor pin received by the anchor base and having an enlarged head with a dimension larger than at least a portion of a respective opening;
- and
- a threaded engagement between the anchor pin and the anchor base with the anchor base having a threaded insert, and the anchor pin having a threaded receiver, the anchor pin and the anchor base engaging rotationally.
A subfloor in combination with flooring supported above a slab by the subfloor, the combination comprising:
- a matrix of resilient pads positioned over the slab;
- a lattice carried by the matrix of resilient pads, the lattice comprising:
- an array of upper cross-arms carried by the matrix of resilient pads and suspended above the slab by the matrix of resilient pads;
- an array of lower cross-arms coupled to and suspended from the array of upper cross-arms;
- openings in the lower cross-arms, each opening having a substantially continuous cross section extending from a top surface of the lower cross-arms to a bottom surface of the lower cross-arms;
- and
- adhesive anchors located in the openings, each adhesive anchor comprising:
- an anchor base with a bottom surface having an adhesive adhering the anchor base to the slab and a threaded insert, the lateral dimension of the anchor base being less than the lateral dimension of the opening in the lower cross-arms;
- and
- an anchor pin received by the anchor base and having a threaded receiver and an enlarged head with a dimension larger than at least a portion of a respective opening;
- wherein the anchor pin and the anchor base are engaged rotationally.
A method of anchoring a subfloor, the method comprising:
- placing a frame carried by a resilient layer above a slab;
- applying an adhesive to a bottom surface of an anchor base of an adhesive anchor;
- inserting the anchor base in an opening in the frame, the opening having a substantially continuous cross section extending from a top surface of the frame to a bottom surface of the frame;
- adhering the adhesive on the bottom surface of the anchor base to the slab;
- attaching an anchor pin of the adhesive anchor to the anchor base;
- and
- advancing the anchor pin towards the anchor base until reaching a desired elevation of the frame with respect to the slab;
- wherein the anchor base and anchor pin define a threaded engagement, with the anchor base having a threaded insert and the anchor pin having a threaded receiver, the anchor pin and anchor base engaging rotationally.
