Embodiment Construction
[0027] The following description serves to disclose the present invention to enable those skilled in the art to carry out the present invention. The preferred embodiments described below are only examples, and those skilled in the art can devise other obvious variations.
[0028] This embodiment provides a large-scale force-bearing ground rail system, including a framework poured into the floor. The framework includes two channel steels 1 and U-shaped steel channels 2 parallel to each other. The openings of the two channel steels 1 face away from each other. Set, the two side ends of U-shaped steel channel 2 are respectively welded to the lower part of two channel steels 1, and then between the two channel steels 1 and U-shaped steel channel 2, a long cavity with a convex cross-section is formed for Place the anchor for the test load.
[0029] Each channel steel 1 is fixedly connected with a plurality of anchor ribs 3 arranged up and down, and the upper end surface of the anc...

The invention discloses a large load bearing ground rail system. The large load bearing ground rail system comprises a framework poured in a floor, the framework comprises two steel channels (1) and a U-shaped steel tank (2), the two steel channels (1) are parallel to each other, the two side ends of the U-shaped steel tank (2) are welded to the lower surfaces of the two steel channels (1) respectively, openings of the two steel channels (1) are arranged back on to each other, a cavity with an inverted T-shaped full-length section is formed between the two steel channels (1) and the U-shaped steel tank (2), multiple anchor bars and multiple anchoring steel angles are fixed to each steel channel (1) in the length direction, and the lower ends of the anchor bars (3) and the lower ends of the anchoring steel angles (4) are welded to lower rebar (11) which is fixed in the floor. The large load bearing ground rail system can be applied to a larger load bearing floor, tension force resistance efficiency is high, safety and reliability are achieved, the amount of steel used is reduced, and the manufacturing cost is saved.
Description
technical field [0001] The invention belongs to the technical field of industrial building structure design and construction, and in particular relates to a large load-bearing ground rail system and a construction method thereof. Background technique [0002] The load-bearing floor is a load-bearing structure that fixes the test object and bears the test load (mainly tension) in the static load test room. Many steel grooves parallel to each other in the length direction and capable of anchoring the test equipment (load-bearing ground rails) are buried on the top of the floor. The distance between different load-bearing ground rails is generally 0.3m~1m. The load-bearing ground rail is the key part that directly bears the test load, and its load-bearing parameter is represented by t / m. In addition to bearing the load, it can also fix the test piece, the load-bearing frame, etc. The large-scale load-bearing floor used for the whole machine test of a large aircraft requires a ...
