Abstract

The invention discloses a U-shaped beam pre-buried channel anti-drawing test device and method. The U-shaped beam pre-buried channel anti-drawing test device comprises a connector, a lengthened rod, acenter hole jack and an anchorage device, wherein the connector is a steel sleeve structure internally provided with a thread, one end of the connector is in threaded connection with the exposed endof a T-shaped bolt in a channel of a U-shaped beam web plate, the other end of the connector is connected with the lengthened rod through thread, the lengthened rod is made of threaded steel, a threadmatched with the connector is arranged at one end, the end is connected with the connector through the thread, the other end penetrates through the center hole jack and then is exposed, and the exposed end is anchored at the rear end of the jack through the anchorage device. The center hole jack is the main device providing a drawing force for tests.

Description

technical field [0001] The invention relates to the technical field of bridges used in civil engineering, and more particularly relates to a U-shaped beam pre-buried channel pullout test device and a test method. Background technique [0002] With the rapid development of urbanization in our country, the construction of urban rail transit has also been developed accordingly. As a new type of urban rail transit bridge structure, the U-shaped beam has a light structure and good noise reduction effect because its section form is a "U"-shaped thin-walled opening section composed of bottom plate, web plate and flange plate. , Low building height, high space utilization, safe driving, beautiful appearance and so on. [0003] In order to meet today's call for energy saving and emission reduction, all urban rail transit in my country has adopted electrification operation. In order to ensure the erection of power supply control cables, optical cables and cables during the electrifi...
