Abstract
Abstract A connector is disclosed for use in assembling load carrying members in frameworks for buildings and the like. Although connectors have been known in the past, they have been too expensive or have been unacceptable because of fabricating tolerances. The present connector is economic to produce, is formed in two parts which may be joined to the appropriate beam or column before leaving the assembly shop. The connector has a first connector plate having at least one hook with a first portion extending outwards from the first plate and a second portion extending substantially parallel to the first plate. A second connector plate is provided with at least one aperture adequate in size for admitting the hook, the second plate being adequate in thickness for the first portion of the hook to contact one edge of the aperture and allow the second portion of the hook to overlap the edge of the aperture.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
237 words
In a skeleton framework for land static structures including buildings, the improvement of a connector assembly for permanently joining two load carrying structural members together, the connector assembly comprising in combination with the framework: a first connector plate permanently attached to one load carrying member, said first connector plate comprising at least two vertical rows of a plurality of hooks, each of said hooks formed from an elongated flap punched our from the face of said first connector plate and comprised of a first portion connected to said first connector plate and extending outwards therefrom at an angle approximately 45* to said first connector plate and a terminal second portion extending substantially parallel to said first connector plate; a second connector plate permanently attached to the other load carrying member, said second connector plate having at least two vertical rows of a plurality of apertures, each of said apertures being adequate in size for admitting the hook and the arrangement and location of apertures corresponding to the arrangement and location of hooks, and said second connector plate having a thickness such that said first portion of said hooks contacts one edge of the coresponding aperture and allows the second portion of said hooks to overlap the edge of the corresponding aperature; and a restraining plate located behind said second connector plate and spaced therefrom a distance greater than the thickness of said second portion of said hook.

Claim 3
Dependent Claim
80 words
The connector assembly according to claim 1, wherein the second plate forms the web of a channel section adapted to have the flanges of the channel attached to a flat surface of one of the load carrying members, the distance between the inside face of the web and the tips of the flanges being greater than the thickness of the second portion of the hook, and said restraining plate comprises said flat surface of one of the load carrying members.
Claim 4
Dependent Claim
37 words
The connector assembly according to claim 2, wherein the channel section forming the second plate is welded to a structural steeL column and the first connector plate is welded to the end of a structural steel beam.
Claim 5
Dependent Claim
44 words
The connector assembly according to claim 2, wherein the first plate is welded perpendicularly to the web or a structural steel beam and the channel section forming the second plate is welded to the end of the web of a second structural steel beam.
Claim 6
Dependent Claim
222 words
In a skeleton framework for land static structures including buildings, the improvement of a connector assembly for permanently joining two load carrying structural members together, the connector assembly comprising in combination with the framework: a first connector plate permanently attached to one load carrying member, said first connector plate comprising at least two vertical rows of a plurality of hooks, each of said hooks formed from an elongated flap punched out from the face of said first connector plate and comprised of a first portion connected to said first connector plate and extending outwards therefrom at an angle approximately 45* to said first connector plate and comprising a stiffening ridge extending throughout said first portion and a terminal, second portion extending substantially parallel to said first connector plate; and a second connector plate permanently attached to the other load carrying member, said second connector plate having at least two vertical rows of a plurality of apertures, each of said apertures being adequate in size for admitting the hook and the arrangement and location of apertures corresponding to the arrangement and location of hooks, and said second connector plate having a thickness such that said first portion of said hooks contacts one edge of the corresponding aperture and allows the second portion of said hooks to overlap the edge of the corresponding aperture.
