Illllllll INVENTOR VINCENT S. PENOTE ATTORNEYS United States Patent 3,418,781 BOLT ANCHOR FOR CONCRETE Vincent S. Penote, Shaker Heights, Ohio, assignor to The Cleveland Trencher Company, Cleveland, Ohio, a corporation of Ohio Filed Jan. 12, 1967, Ser. No. 608,836 Claims. (Cl. 52-699) ABSTRACT OF THE DISCLOSURE Background of the invention An choring devices heretofore used for embedment in concrete have generally embodied metallic shells which are subject to deterioration by rust and which are relatively heavy and expensive to manufacture. Additionally, the shape of prior devices has mitigated against the attainment of an effective interlock with the concrete after the concrete has set.
Summary of the invention The invention embodies a one piece shell preferably of thermoplastic material which has a threaded socket opening from one end for receiving the shank of the bolt by means of which the shell may be attached to a concrete form before the concrete is poured. The shell is also provided with flanges which are so formed as to provide a firm and effective interlock with the concrete so as to prevent rotation of the anchor with respect to the concrete after the form has been removed.
Brief description of the drawings In the drawings,
FIG. 1 is a side elevation of an anchoring device embodying the present invention;
FIG. 2 is an end elevation as viewed from the right hand end of FIG. 1;
FIG. 3 is a section taken on a plane indicated by the line 3-3 of FIG. 2.
Description of the preferred embodiment The anchoring device of the present invention comprises a one piece shell preferably of thermoplastic material, such as polyvinylchloride, having a body portion 10, a head flange 11 and a base flange 12 disposed at the ends of the body portion. The body portion also has an internally threaded socket 15 which is open at 16 adjacent the flange 11, and is adapted to receive the threaded shank 20 of a bolt 21 for clamping it to a concrete form 22 in the desired location. The body portion preferably em- Patented Dec. 31, 1968 ICC bodies the shape of a right frustum, with the base ter- Ininating in the flange 12.
To lock the shell after the concrete has been poured around it, the flange 11 may be provided with one or more peripheral indentations 30 which extend through the flange in an axial direction and are adapted to receive concrete which flows around the shell during the pouring operation. Additionally, the flange 12 preferably has an oblate form with the flattened portions 31 and 32 preferably disposed in alignment with the recesses 30. Such formations permit the concrete to flow readily entirely around the shell thereby to form an effective interlock which inhibits rotation of the shell with respect to the concrete.
After the concrete has set, the bolt 21 is removed with the form 22, whereupon the socket 20 presents a clean surface for receiving the bolt by means of which an article is to be fastened to the concrete.
By making the anchor of thermoplastic material the shell will be relatively light in weight and yet will ossess sufl'icient strength and rigidity to serve adequately as a bolt anchor within concrete.
I claim:
1. An anchoring device for use in concrete comprising, a shell of polymeric material having an internally threaded socket adapted to receive a threaded member therein, said socket being open at one end and closed at the other end, said shell including a frustrum-shaped body portion with one end of said body portion being larger in transverse dimension than the other end, said body portion having radially outwardly projecting flanges disposed at opposite ends thereof, one of said flanges being noncircular in configuration and including oppositely disposed generally flattened portions adapted for abutting engagement with said concrete to prevent axial rotation of one end of said shell, and the other of said flanges including at least one peripheral recess opening radially outwardly and adapted to be filled with concrete to lock the other end of said shell against rotation.
2. An anchoring device in accordance with claim 1, wherein said socket is generally uniform in longitudinal cross section, and the transverse dimension of said body being increased in a direction away from said open end whereby said axial movement is prevented when in the embedded position.
37 An anchoring device in accordance with claim 1, wherein the number of recesses in the other of said flanges is equal to the number of flattened portions, and said recesses being centrally aligned with said flattened portions.
4. An anchoring device adapted for embedding in concrete comprising, a shell of plastic material having an internally threaded socket adapted to receive a threaded member therein, said socket being open at one end and closed at the other end, said shell including a generally right frustrum-shaped body portion with one end of said body having a larger transverse dimension than the other end, said body portion having radially outwardly projecting flanges disposed at the opposite ends thereof, one of said flanges being oblate in configuration including diametrically opposed generally flattened portions, the other of said flanges including peripheral recesses opening radially outwardly, said recesses being disposed in alignment with said flattened portions, said socket being generally uniform in longitudinal cross section, the transverse dimension of said body portion being increased in a direction away from said open end, said flanges disposed in abutting embedded relation in said concrete to prevent axial rotation, and said flanges and said body disposed in abutting embedded relation in said concrete to prevent axial rotation and lateral movement of said shell when in the installed position.
5. An anchoring device in accordance with claim 4, wherein said shell is made from a thermoplastic material.
