Abstract
Abstract This invention relates to jolting tables for manufacturing structural members from concrete. Such tables normally comprise a vibratory plate on a support structure which is used as a mould base for the member and a jolter is mounted below this plate. In accordance with the invention, the support structure is rigid and the plate is freely mounted thereon without resilient cushioning in such a fashion that it may be laterally displaceable within predetermined limits: the jolter is movable along a jolting rail that extends substantially over the whole length of the plate, said rail being secured directly to the inside of the plate. The support structure is rigidly connected to a base member which may be a prepared slab of concrete or the ground. The support framework may be made from steel or wooden members.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
176 words
A jolting table for manufacturing finished structural parts of concrete, comprising a plate for use as a mold base for the finished part and vibratable by a jolter mounted therebelow, said plate being freely mounted on a rigid support structure without resilient cushioning and laterally displaceable within predetermined limits, a jolting rail extending substantially over the entire length of said plate to enable said jolter to be moved therealong, said jolting rail being secured directly to the underside of said plate, said support structure being rigidly connected to a base member and consisting of a set of supports for said plate, arranged parallel to the jolting rail and resting on at least two support frames arranged transversely to the longitudinal direction of said supports, each supporting frame consisting of a lower tie member extending over the entire width of said Plate, and an upper tie member extending parallel over said lower tie member and being interrupted in the area of said jolting rail, at least four vertical bars extending between said upper and lower tie members.
Claim 2
Dependent Claim
176 words
A jolting table for manufacturing finished structural parts of concrete, comprising a plate for use as a mold base for the finished part and vibratable by a jolter mounted therebelow, said plate being freely mounted on a rigid support structure without resilient cushioning and laterally displaceable within predetermined limits, a jolting rail extending substantially over the entire length of said plate to enable said jolter to be moved therealong, said jolting rail being secured directly to the underside of said plate, said support structure being rigidly connected to a base member and consisting of a set of supports for said plate, arranged parallel to the jolting rail and resting on at least two support frames arranged transversely to the longitudinal direction of said supports, each supporting frame consisting of a lower tie member extending over the entire width of said Plate, and an upper tie member extending parallel over said lower tie member and being interrupted in the area of said jolting rail, at least four vertical bars extending between said upper and lower tie members.
Claim 3
Dependent Claim
23 words
A jolting table as claimed in claim 1, wherein said plate is made from steel, plastics material or wood with a plastics coating.
Claim 4
Dependent Claim
52 words
A jolting table as claimed in claim 1, wherein said support structure rests on a set of base beams and is connected to the base via member by floor stays which bear on anchoring beams extending parallel to said base beams and resting on the lower tie member of said supporting frame.
Claim 5
Dependent Claim
31 words
A jolting table as claimed in claim 1, wherein said vertical bars are connected so as to be resistant to bending by means of strengthening plates secure to said tie members.
Claim 6
Dependent Claim
36 words
A jolting table as claimed in claim 1, wherein said plate projects on at least two opposing edges beyond said supporting structure, and wherein reinforcing or stop profiles are secured to said plate at said edges.
Claim 7
Dependent Claim
36 words
A jolting table as claimed in claim 1, wherein said support structure is covered on its four side walls with plates to form an inner chamber sealed on all sides in which heating means are arranged.
Claim 8
Dependent Claim
21 words
A jolting table as claimed in claim 1, wherein the intermediate spaces between the base beams are filled with heat-insulating material.
