Hogging bending moment rebar suspension device with capabilities of recycling and height adjustment and use method

Abstract

The invention provides a hogging bending moment rebar suspension device with capabilities of recycling and height adjustment and a use method. The rebar suspension device comprises a 8-shaped rebar suspension frame (1) welded by square tubes, precast concrete support column fixing sleeves (2) welded to four corners and the middle of the bottom surface of the rebar suspension frame, precast concrete support columns (3) capable of being inserted into the precast concrete support column fixing sleeves (2) from the bottoms, steel plates (4) uniformly welded on inner side walls of two long sides ofthe rebar suspension frame and provided with long slotted holes, rebar hooks (5) capable of being inserted into the long slotted holes as well as handles (6) welded on top surfaces of two short sidesof the rebar suspension frame, wherein hangers of the rebar hooks are vertical screw rods, and nuts (7) are mounted on the screw rods in a matched manner. The problems of lower qualification rate ofprotective layers of hogging bending moment rebars and deviated floor thickness control caused by deformation, subsiding and displacement of the hogging bending moment rebars of floors are solved effectively, and the qualification rate of protective layer thickness of the hogging bending moment rebars and floor thickness is increased. The rebar suspension device is simple in structure and convenient to mount and dismount.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a negative moment steel bar suspension device and an application method thereof. Background technique [0002] During the construction process of the project, the negative moment reinforcement of the floor is generally thin. During the construction process, it is easy to cause deformation, collapse and displacement of the negative moment reinforcement, resulting in the thickness of the protective layer of the negative moment reinforcement not meeting the specification requirements, and the pass rate is low. Low, the phenomenon that the thickness of the floor slab does not meet the specifications and design requirements is common in construction. Contents of the invention [0003] In order to solve the above-mentioned problems of low qualified rate of floor negative moment reinforcement protective layer and control deviation of floor thickness, the present inventio...
