Abstract

There is provided a curb-casting machine particularly useful in continuously casting high column concrete forms and which is characterized by a novel multistaged open-ended slip-form. The slip-form is carried upon a movable frame which is desirably, although not essentially, adjustable, which is in turn supported on a carrying frame. Locomotive means are provided for moving the carrying frame along a surface on which the casting is being laid.

Claims

1. A curb casting machine for continuously casting high column forms comprising in combination:

a. an open-ended traveling slip-form to compact concrete, wide at the base and with successively narrower portions towards the top, having sides which are in stepped vertical relationship, said narrower portions being of increasing height converging upwardly and in stepped horizontal relationship converging rearwardly;

b. means for supplying a settable material to the forward portion of said converging form, whereby said material is compacted rearwardly and upwardly as the form moves forward.

2. The apparatus of claim 1, including in addition means for vibrating said form.

3. The apparatus of claim 1, including means for lowering and raising said form.

4. The apparatus of claim 1, including oppositely directed screw conveyor means for supplying said settable material.

5. The apparatus of claim 1, including guide means for following a predetermined path.

6. The apparatus of claim 1, wherein said settable material is concrete.
