Abstract
Abstract A longitudinal joint is supported adjacent the paving form by a plurality of hangers, each of which includes an attaching portion for affixing to the paving form, thus obviating the need for chair supports or other known devices for supporting a longitudinal joint. Each of these hangers includes a support-holder portion extending at an acute angle with respect to the paving form, defining an angle for receiving a portion on the longitudinal joint. This both supports the joint vertically and restrains it against horizontal movement away from the paving form. In addition the longitudinal joint is modified so that the normal apertures for receiving the extension of the tie bar, instead of being formed in a flat surface of the joint, are provided in a plane substantially perpendicular to the length or axis of the joint. The portions of the joint adjacent each bar-receiving aperture are concave and convex, in opposite directions, to allow the tie bar to be inserted behind the joint after the joint is affixed in place and supported on the road form. The tie bar can have its extremity farthest away from the joint bent at right angles to engage the ground and thus to form a support for the tie bar, doing away with the need for a bar support. Various types of hangers can be provided, for use with both metal and wooden longitudinal joints. The attaching portion can be a hook extending through an aperture in the paving form, or a longer extension which goes over and around the top of the form. With wooden forms, the attaching portion of the hanger can be a simple eye for receiving a nail to support the hanger adjacent the form.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
205 words
The combination of a paving form and: a plurality of hangers, each having a straight connector portion, a support-holder portion extending from one end of the connector portion, and an attaching portion extending from the other end of the connector portion attaching each hanger to the form so that the support-holder portion extends at an acute angle relative to the connector portion: a longitudinal joint, having a base portion and a pair of side walls, the longitudinal joint being positioned against the form with the base portion spaced from and substantially parallel to the form, one side wall of the longitudinal joint being received in the acute angle defined by each hanger connector and support-holder portions, both to support the joint vertically and restrain the joint from horizontal displacement away from the form, which joint also defines a plurality of concave-convex apertures for receiving a cylindrical tie bar along the axis of the longitudinal joint; and a plurality of tie bars, each having a first end portion and a second end portion extending at right angles to the first end portion, with the second end portion inserted through one of the concave-convex apertures of the joint into the space between the form and the joint.
Claim 2
Dependent Claim
205 words
The combination of a paving form and: a plurality of hangers, each having a straight connector portion, a support-holder portion extending from one end of the connector portion, and an attaching portion extending from the other end of the connector portion attaching each hanger to the form so that the support-holder portion extends at an acute angle relative to the connector portion: a longitudinal joint, having a base portion and a pair of side walls, the longitudinal joint being positioned against the form with the base portion spaced from and substantially parallel to the form, one side wall of the longitudinal joint being received in the acute angle defined by each hanger connector and support-holder portions, both to support the joint vertically and restrain the joint from horizontal displacement away from the form, which joint also defines a plurality of concave-convex apertures for receiving a cylindrical tie bar along the axis of the longitudinal joint; and a plurality of tie bars, each having a first end portion and a second end portion extending at right angles to the first end portion, with the second end portion inserted through one of the concave-convex apertures of the joint into the space between the form and the joint.
Claim 3
Dependent Claim
40 words
The combination of claim 1, in which the attaching portion of each hanger includes a U-shaped bend and a leg extending substantially parallel to the connector portion, to define a hook which extends through an aperture in the paving form.
Claim 4
Dependent Claim
65 words
The combination of claim 1, in which the attaching portion of each hanger has a first leg extending at a right angle from the straight connector portion, and a second leg extending at a right angle from the first leg and substantially parallel to the straight connector portion, defining with the connector portion an inverted U-shape which fits over the top of the paving form.
Claim 5
Dependent Claim
40 words
The combination of claim 1, in which the attaching portion of each hanger defines a substantially circular eye, which receives a nail or similar fastener driven through the eye into the paving form to support the hanger adjacent the form.
Claim 6
Dependent Claim
269 words
The combination of a paving form and: a plurality of hangers, each having a straight connector portion for abutting the form, a support-holder portion extending from one end of the connector portion, and an attaching portion affixed to the other end of the connector portion attaching each hanger to the form, with the support-holder portion defining an acute angle with the connector portion; a longitudinal joint, having a generally flat base portion and a pair of side walls, each side wall extending at an acute angle, measured with respect to an extension of the base portion, which is substantially equal to the acute angle defined between the hanger connector portion and support-holder portion, the longitudinal joint being positioned against the form with the base portion spaced from the substantially parallel to the form, one side wall of the joint being received between each hanger connector portion and each hanger support portion, both to support the joint vertically and restrain the joint from horizontal displacement away from the form, which joint also defines a plurality of concave-convex apertures for receiving a cylindrical tie bar along the axis of the longitudinal joint; and a plurality of the tie bars, each having a straight center portion, a first end portion extending at right angles to the center portion and inserted through one of the concave-convex apertures into the space between the form and the joint, and a second end portion, extending at right angles with respect to both the center portion and the first end portion, to touch the ground and support the tie bar center portion substantially parallel to the ground.
Claim 7
Dependent Claim
269 words
The combination of a paving form and: a plurality of hangers, each having a straight connector portion for abutting the form, a support-holder portion extending from one end of the connector portion, and an attaching portion affixed to the other end of the connector portion attaching each hanger to the form, with the support-holder portion defining an acute angle with the connector portion; a longitudinal joint, having a generally flat base portion and a pair of side walls, each side wall extending at an acute angle, measured with respect to an extension of the base portion, which is substantially equal to the acute angle defined between the hanger connector portion and support-holder portion, the longitudinal joint being positioned against the form with the base portion spaced from the substantially parallel to the form, one side wall of the joint being received between each hanger connector portion and each hanger support portion, both to support the joint vertically and restrain the joint from horizontal displacement away from the form, which joint also defines a plurality of concave-convex apertures for receiving a cylindrical tie bar along the axis of the longitudinal joint; and a plurality of the tie bars, each having a straight center portion, a first end portion extending at right angles to the center portion and inserted through one of the concave-convex apertures into the space between the form and the joint, and a second end portion, extending at right angles with respect to both the center portion and the first end portion, to touch the ground and support the tie bar center portion substantially parallel to the ground.
