TL;DR: In this article, a paving machine consisting of a material bunker for receiving a construction material (M), a chassis, an operator stand, and at least one optical projector is configured to generate a projection in the visible spectrum on the substrate (U) laterally and/or in front of the chassis (3) when seen in the construction direction (F).
Abstract: The invention relates to a paving machine (1) comprising a material bunker (2) for receiving a construction material (M), a chassis (3), an operator stand (6) which is arranged behind the material bunker (2) when seen in the construction direction (F), a paving screed (7) which can be leveled for assembling the construction material (M) onto a substrate (U), a material conveying unit (8) which is configured to transport the construction material (M) from the material bunker (2) to the paving screed (7), and at least one optical projector (9) which is configured to generate at least one projection (10) in the visible spectrum on the substrate (U) laterally and/or in front of the chassis (3) of the paving machine (1) when seen in the construction direction (F). The projection (10) is visible to an operator of the paving machine (1) from the operator stand (6) when seen in the construction direction (F).

TL;DR: An adjustable screed support for supporting one end of a screed during screeding of cement on a wall generally comprises a support bracket for attachment to the wall support structure including a stand-off portion extending outward, away from the wall supports.
Abstract: An adjustable screed support for supporting one end of a screed during screeding of cement on a wall generally comprises a support bracket for attachment to the wall support structure including a stand-off portion extending outward, away from the wall support structure; and an elongate beam which is adjustably attached to the support bracket stand-off such that the distance of the top side of the beam from the wall support structure and the angle of the line of the beam the wall support structure are variable. The beam top side in side view is a straight line. The beam has holes side to side through its web portion and the support bracket stand-off portion has conguent holes. Cement from each side of the screed support flows through the holes and bonds to the cement on the other side.

TL;DR: In this article, the main section and telescopic section screeds are arranged on the left side and/or the right side of the main screed and include a cross slope framework, a cross-slope driver, at least two multistage sliding pipes, a telescopic frame, an elevation difference driver and a base plate.
Abstract: A telescopic screed includes main section and telescopic section screeds. The main section screed includes a screed frame and a base plate. The telescopic section screeds are arranged on the left side and/or the right side of the main section screed and include a cross slope framework, a cross slope driver, at least two multistage sliding pipes, a telescopic frame, a telescopic driver, a telescopic section frame, a telescopic section base plate and an elevation difference driver. The cross slope framework is pivotally connected with the main section screed to adjust the cross slope. The multistage sliding pipes are used for transversely guiding the telescopic frames to achieve the telescopic ability of the telescopic section screeds. The telescopic section frame is connected with the corresponding telescopic frame to move up and down to adjust the relative height between the telescopic section frame and the telescopic frame.

TL;DR: In this article, a road paver-finisher with a semi-floating screed unit of the type in front of which operates a system of augers for transverse distribution of the mixture to be laid, has the auger(s) (15) mounted on a sub-frame (32) equipped with arms (34) that remain approximately parallel to the arms (16) of the screed.
Abstract: of EP0774542A road paver-finisher having a screed unit of the semi-floating type in front of which operates a system of augers for transverse distribution of the mixture to be laid, has the auger(s) (15) mounted on a sub-frame (32) equipped with arms (34) that remain approximately parallel to the arms (16) of the screed (11), the front ends (35) of the arms (34) of the sub-frame (32) being mounted on the tractor (10) at their centers of rotation (36), the latter always being situated very close to the centers of rotation and traction (18) of the front end (17) of the arms (16) of the screed (11), the upward and downward movement of the augers taking place as a motion of rotation around the centers (36) by means of actuators, for example hydraulic pistons (40') mounted on the tractor (10) that engage on the sub-frame (32) or on the arms (34)
