Abstract

The invention relates to supports for apparatus for transferring weight loads from one concrete structure to another. The devices are particularly suited for concrete highway construction. The support apparatus is used to position joint dowels that extend across paving joints between adjoining concrete slabs. The support apparatus comprises a first and a second support, each positioned on opposing sides of the paving joint. Each of the first and second supports comprise at least one longitudinally extending member having at least two cross members attached thereto such that one end of the cross member extends outwardly beyond the member. At least one clip comprising a body having a cavity therein, a gripper connected to the body and a cylindrical sleeve connected to the body is attached to each support. The clip is mounted to the end of a cross member so that the first end of the cross member is received into the cavity of the body and the attached gripper grasps the adjacent portion of the member. The sleeves are sized and configured to receive a dowel therein. When the first and second supports are spaced apart a predetermined distance from one another on opposing sides of a construction joint and opposing sleeves are aligned with one another, the first end of a dowel is receivable in one sleeve and the second end of the dowel is receivable in the opposing sleeve.

Claims

1. A support apparatus for placement of a load transfer dowel in concrete constructions comprising:

a first and a second support, each support comprising;

a longitudinal member,

two cross members, said two cross members each having a first end and a second end, said first ends of said two cross members being spaced apart from one another and each of said two cross members being attached to said longitudinal member proximal said first ends of said two cross members, such that said first end of at least one of said two cross members extends outwardly a predetermined distance from said longitudinal member; and

at least one clip being attached to said longitudinal member, said clip comprising;

a body having a cavity therein and an opening into said cavity, said opening and said cavity being sized and configured to receive said first end of one of said two cross members, the other cross member of said two cross members being spaced apart from said clip;

a gripper connected to said body such that said gripper grasps said longitudinal member; and

a cylindrical sleeve having a first end and a second end, at least one of said ends being open, said sleeve being sized and configured to receive a dowel therein through said open-end, said sleeve being connected to said body;

whereby, when said first and second supports are spaced apart a predetermined distance from one another, and a sleeve mounted on said first support is aligned with a sleeve mounted on said second support, the one end of a dowel is receivable in said sleeve of said first support and the other end of the dowel is receivable in said sleeve of said second support.

2. A support apparatus as in claim 1, wherein said body of said clip further comprises a U-shaped element, said U-shaped element having a first end and a second end, said first end being attached to said body adjacent said opening in said body and said second end of said U-shaped element extending outwardly therefrom such that when said first end of said cross member is inserted through said opening and into said cavity, said gripper grasps said member, and a portion of said cross member is received by said U-shaped element.

3. A support apparatus as in claim 2, wherein said second end of said U-shaped element of said body extends outwardly beyond said gripper.

4. A support apparatus as in claim 1, wherein said gripper comprises a resilient curved arm that extends outwardly from said body such that said member is captured between said arm and said body.

5. A support apparatus as in claim 1, wherein each said support comprises a pair of longitudinal members extending longitudinally generally parallel to one another, each said member of said pair of members being attached to said cross members.

6. A support apparatus as in claim 1, wherein said first and second supports each comprise a plurality of clips, whereby a plurality of dowels are supportable therebetween.
