Abstract
Abstract A method and device for collecting a layer of concrete paving bricks forming a brick disk in the form of a stretcher bond which may be used as one setting unit, is characterized in that the layer of the paving bricks is clamped together laterally with a collecting clamp with respect to their longitudinal axes for aligning purposes and, after releasing the collecting clamps, each row of bricks is individually clamped to their respective position at their head ends with clamps. The clamps with the clamped rows of bricks are then displaced with respect to each other in a parallel direction to achieve the desired setting arrangement and the collecting clamp is again engaged.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
142 words
A method of assembling a layer of concrete paving bricks forming a brick disk in the form of a stretcher bond which may be used as one setting unit, comprising the steps of: aligning a layer of bricks comprising successive rows of bricks in a desired longitudinal direction by clamping said layer of bricks together laterally by means of at least one collecting clamp; after releasing said collecting clamp, individually clamping each row of bricks at their longitudinal ends by means of clamping members; displacing the clamping members and their associated clamped row of bricks in a parallel longitudinal direction with respect to the other clamping members and their associated clamped row of bricks so as to arrange said rows in a desired setting pattern; and clamping said layer of bricks together laterally by means of said at least one collecting clamp.
Claim 2
Independent Claim
142 words
A method of assembling a layer of concrete paving bricks forming a brick disk in the form of a stretcher bond which may be used as one setting unit, comprising the steps of: aligning a layer of bricks comprising successive rows of bricks in a desired longitudinal direction by clamping said layer of bricks together laterally by means of at least one collecting clamp; after releasing said collecting clamp, individually clamping each row of bricks at their longitudinal ends by means of clamping members; displacing the clamping members and their associated clamped row of bricks in a parallel longitudinal direction with respect to the other clamping members and their associated clamped row of bricks so as to arrange said rows in a desired setting pattern; and clamping said layer of bricks together laterally by means of said at least one collecting clamp.
Claim 3
Independent Claim
202 words
A device for assembling a layer of concrete bricks forming a brick disk in the form of a stretcher bond which may be used as one setting unit, comprising: a pair of spaced-apart, parallel support arms including means for detachably mounting said support arms on a hoisting device and a clamping bar coupled to one end of said support arms and actuable clamping means coupled to the opposite ends of said support arms which cooperate with said clamping bar to engage and retain the layer of bricks in an assembled manner; a plurality of spaced-apart, parallel support legs coupled to and disposed generally normally to said support arms, said support legs each being fixedly coupled to one of said support legs and slidably coupled to the other of said support legs in a successive alternate manner so as to permit displacement of said support legs in a parallel manner with respect to each other and over a row of paving bricks of the brick disc, said support legs each having clamping members disposed at the opposite ends thereof, at least one of which is moveable; and actuating means operatively coupled to at least one of the clamping members of each support leg.
Claim 4
Independent Claim
202 words
A device for assembling a layer of concrete bricks forming a brick disk in the form of a stretcher bond which may be used as one setting unit, comprising: a pair of spaced-apart, parallel support arms including means for detachably mounting said support arms on a hoisting device and a clamping bar coupled to one end of said support arms and actuable clamping means coupled to the opposite ends of said support arms which cooperate with said clamping bar to engage and retain the layer of bricks in an assembled manner; a plurality of spaced-apart, parallel support legs coupled to and disposed generally normally to said support arms, said support legs each being fixedly coupled to one of said support legs and slidably coupled to the other of said support legs in a successive alternate manner so as to permit displacement of said support legs in a parallel manner with respect to each other and over a row of paving bricks of the brick disc, said support legs each having clamping members disposed at the opposite ends thereof, at least one of which is moveable; and actuating means operatively coupled to at least one of the clamping members of each support leg.
Claim 5
Dependent Claim
24 words
The device according to claim 2, wherein said actuating means includes a conventional Bowden cable for each moveable clamping member of each support leg.
Claim 6
Dependent Claim
23 words
The device according to claim 3, wherein said actuating means includes an operating cylinder for simultaneous actuation of each of said Bowden cables.
Claim 7
Dependent Claim
26 words
The device according to claim 2, 3, or 4, wherein each of said clamping members includes a roller element which is engageable with a brick surface.
Claim 8
Dependent Claim
32 words
The device according to claim 2, 3, or 4, wherein each actuable clamping member is telescopically moveable with respect to its associated support leg by means of each of said Bowden cables.
Claim 9
Dependent Claim
45 words
The device according to claim 2, wherein said actuable clamping means for the collective clamping of the bricks is disposed on a clamping shaft which is mounted on the other ends of said support arms in a parallel manner with respect to said clamping bar.
Claim 10
Dependent Claim
31 words
The device according to claim 7, wherein said clamping bar and said clamping shaft each have a clamping jaw mounted at the center thereof between said support arms opposing one another.
Claim 11
Dependent Claim
25 words
The device according to claim 8, additionally including a plurality of alignment jaws disposed on said clamping shaft, laterally of said clamping jaw mounted thereon.
Claim 12
Dependent Claim
27 words
The device according to claim 7, additionally including an operating cylinder coupled to said clamping shaft for rotating said clamping shaft between an operative and inoperative position.
Claim 13
Dependent Claim
41 words
The device according to claim 2, wherein said means for detachably mounting comprises hinged yokes coupled to each of the support arms having free ends which are coupled with a detachment eyelet by means of a ball and socket pivot joint.
Claim 14
Dependent Claim
20 words
The device according to claim 2, wherein said support arms and support legs have clamping members made of pipe profiles.
