Methods and apparatuses are provided for improved traffic control devices including a continuous central hanger support system that is integral to the traffic control device and provides a central load path. In an embodiment of the invention, the terminal housing and traffic signal housing of the traffic control device can be included in a single unit housing. A single unit housing can also include an integral backplate. Also provided are span wire clamps, tether clamps, and mast arm clamps that can be used to affix the continuous central hanger of the traffic control device to various fixtures such as a single span wire, two span wires, a pole or a mast arm. The continuous central hanger integrated with the single unit housing can provide the traffic control device with improved securement of electrical components and structural stability for survivability during high wind events as compared to conventional traffic signal devices.

The continuous central hanger integrated with the single unit housing can provide the traffic control device with improved securement of electrical components and structural stability for survivability during high wind events as compared to conventional traffic signal devices.

The invention relates to a method and a device for detecting the compressive strength of concrete by a bending method. The method comprises the following steps of: recording rupture load during damage of the concrete and an area of a damaged section to calculate bending strength; and establishing a correlativity between the bending strength and the corresponding strength of a cubic test piece with the side length of 150mm to deduce the compressive strength of the concrete. By applying fracture resistance force to a test piece, influencing factors in the testing process are reduced and the testing accuracy is improved; moreover, the testing process is simple and feasible. The invention can be widely applied to detection of strength of concrete structure entities in the building industry, railway industry, traffic industry, water transportation industry, harborwork industry and the like.
