A side bracket is for a link for a line-routing device. The side bracket has a longitudinal periphery which extends in a longitudinal direction of the side bracket and on which a running surface is formed. The side bracket has a roller which is mounted so as to be rotatable about an axle. The axle is disposed so as to be parallel to the running surface and perpendicular to the longitudinal direction. A spacing between the running surface and the axle is variable in a damped manner. The roller, at least in a first position, protrudes from the running surface.

The present application relates to the technical field of engineering construction and provides a rebar, a device and a construction method for 3D-printing a concrete interlayer structure. The rebar at least comprises: a body in the form of a chain structure, comprising a plurality of sub-parts mutually spliced, wherein the body is adapted for being sandwiched between two adjacent upper and lower cement-based slurry layers; a rotatable joint arranged between two adjacent sub-parts in such a way that the two adjacent sub-parts are rotatably connected to each other; insertion members, wherein both sides of each of the sub-parts are provided with the insertion members extending away from the center of each of the sub-parts, wherein the insertion member on one side of each of the sub-parts is adapted for being inserted in an upper cement-based slurry layer, and the insertion member on an opposite side of each of the sub-parts is adapted for being inserted in a lower cement-based slurry layer. In summary, the rebar can simultaneously enhance the bearing capacity of the printed structure both in the horizontal direction and in the vertical direction, improve the overall connection strength of the printed structure, so that the building structure is not prone to damage or collapse, which is conducive to reducing any potential safety hazard.

Monitoring systems for energy chains which guide lines, and which are displaceable along a displacement path and thereby form a movable strand, a stationary strand, and a deflection arc therebetween. According to a first aspect, one or multiple sensors are arranged stationary and form a detection path along the displacement path of the energy chain, in order to react to an approaching and/or contact of the energy chain. According to a second aspect, a plurality of sensor modules are distributed along the energy chain. In this case, each sensor module has a measurand detector and a communication unit for transmitting outputs to an evaluation unit. The first and the second aspect allow function monitoring, for example for the purpose of a safety shutdown. According to a third aspect, a sensor module is arranged on the driver-side end region. The module has a sensor for the quantitative detection of a kinematic parameter of the end region, as well as a communication unit for transmitting output data depending on detected kinematic parameters. This allows an application-dependent prediction of the remaining service life of energy chains.
