Abstract
A tie anchor for use in reinforced sandwich panels of cast concrete, to support a face panel on a carrier panel by reaching through an intermediate insulating panel, the tie anchor being a sheet metal stamping with a central A-shaped end portion on one axial end and a V-shaped recess flanked by two tapered end portions on the other axial end. Hook portions formed of the tapered end portions are engageable over a rod of a reinforcing steel rod mesh and attachable thereto by means of positioning rods which are inserted through transverse positioning bores in the hook portions.
Claims10
A tie anchor for cast sandwich panels and the like, particularly sandwich panels of the type which comprise two spaced panels of steel-rod-reinforced cast concrete or comparable reinforced building wall material and an intermediate insulating layer or insulating air space, wherein one of the two panels is a carrier panel and the other one is a face panel and the tie anchor is designed to support the face panel on the carrier panel by having at least one end portion embedded in each panel, as the latter are cast in succession, the tie anchor comprising:
- a substantially flat tie anchor body having a longitudinal axis;
- at least one convergingly tapered end portion defined by each axial end of the tie anchor body, at least one of said axial ends defining two transversely spaced, convergingly tapered end portions;
- and
- at least one positioning bore in each of said tapered end portions, for the insertion therethrough of a tie anchor positioning rod;
- and wherein
- the tapered end portion, or end portions, respectively, on one of the two axial ends of the tie anchor body form a hook portion around a half-loop bend, at a bending line which extends transversely to the longitudinal axis of the tie anchor body;
- each hook portion includes a bent hook portion extending at a distance from an unbent hook portion which is aligned with the tie anchor body, so that the hook portion, or portions, respectively, are engageable over a reinforcing rod in one of said two panels;
- and
- each hook-portion-forming tapered end portion has at least one pair of aligned positioning bores in its bend and unbent hook portions, for the insertion of a positioning rod through said pair of aligned bores, which positioning rod locks the tie anchor to the reinforcing rod by engaging the side of the reinforcing rod opposite the side engaged by the hook portion, or hook portions, respectively, thereby positioning and orienting the tie anchor in relation to the reinforcing rod during casting of the first panel.
