The invention relates to a paving screed for a paver, with a basic screed and with at least one lateral extendable screed part which is connected to the basic screed via hydraulically actuable tensioners. The height of the extendable screed part can be adjusted via a height setting device which comprises vertical spindles which are coupled to the extendable screed part and are held on the basic screed rotatably relative to the latter. The spindles are adjustable via a common drive motor, it being possible, as a result of the actuation of the drive motor, to trigger a release of the hydraulically actuable tensioners for the duration of actuation. The extendable screed part is also connected to the basic screed via spring-biased screws.

Paving screed for a paver

A paver screed has a main screed with two outer side walls, at least one of the side walls being provided with insertion orifices for the releasable mounting of at least one lateral screed extension by means of fastening elements capable of being inserted through the insertion orifices. A screed extension has fastening elements that comprise hydraulic cylinders which each have a piston that is spring-biased into an initial, retracted position. The cylinders are actuated by hydraulic fluid to displace or extend the piston against the biasing action of the spring. Preferably, the hydraulic cylinders are connected a hydraulic circuit of the main screed. The piston of each hydraulic cylinder carries a shank capable of being inserted through a proximal insertion orifice and which are preferably provided with an abutment element configured for attaching the cylinder to the sidewall of the main screed.
