Problems solved by technology

[0008] The object of the present invention is to provide a hanging structure of prefabricated concrete double T-slabs and its construction method, to solve the problems of inconvenient roof welding operation, inability to supplement hanging points, and force transmission in the hanging structure at the cantilever end of the existing hanging structure. Concentrate on the technical problem that the use range of the bearing capacity of the horizontal roof is narrow; and solve the technical problem that the rib beams in the slab-rib hanging structure in the existing hanging structure are not directly stressed, and are prone to punching and shearing damage

Abstract

The invention provides a prefabricated concrete double-T type plate suspension structure and a construction method thereof. The prefabricated concrete double-T type plate suspension structure comprises a double-T type plate, and further comprises a cantilever end suspension structure and a plate rib suspension structure, the cantilever end suspension structure comprises cantilever ends of the double-T type plate on both sides, a connecting structure, an additional horizontal tie structure, a hanging rib, a hanging part and a joint sealing material, and the plate rib suspension structure comprises rib beams, top plates on both sides of the rib beams, a rib-penetrating steel sleeve, an upper inverted-U-shaped snap ring and a lower U-shaped snap ring. Or a laminated concrete layer is arrangedon the upper side of the double-T type plate, and the hanging rib is fixedly connected with a laminated bar-mat reinforcement. The prefabricated concrete double-T type plate suspension structure andthe construction method thereof are convenient to construct and are suitable for two situations of pre-burying before plate construction and later additionally-arranging after plate construction, a hanging node can be used for hanging of a suspended ceiling, an air duct, a lamp and other pipelines, and the prefabricated concrete double-T type plate suspension structure and the construction methodthereof are suitable for floor structures or roof structures and can further be used for connection of other prefabricated beam-plate members.

Description

technical field [0001] The invention relates to the field of hanging prefabricated component structures, in particular to a hanging structure of a prefabricated concrete double T plate and a construction method thereof. Background technique [0002] Prestressed concrete double T-slab is a prefabricated load-bearing member with beam and slab integrated. It uses high-strength steel wire or steel strand and high-performance concrete to optimize the design of beam height and slab thickness. To the simple and beautiful components. In order to achieve the purpose of cost-effectiveness, the double T-slabs are respectively the horizontal roof and the vertical rib beam. The thickness of the roof is very thin, and the height commonly used in China is 40mm-50mm at present. The cantilever length of the end of the horizontal roof relative to the rib beam is 490mm-740mm. [0003] In modern architectural design, there are often situations where air ducts or suspended ceilings need to be ...
