Utility model content
Technical problem to be solved in the utility model is: a kind of novel building floor concrete casting levelling device is provided, solves the planeness technical problem of the smaller reinforced concrete floor surface layer of multi storied factory building superstructure floor and vertical member spacing.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of novel building floor concrete casting levelling device, and comprise by orthogonal upper transverse reinforcement, longitudinal reinforcement and lower horizontal steel bar welding and connect the supporting steel bar forming, also comprise:
Be welded in the nut of the end of described upper transverse reinforcement, in described nut, be connected with hollow screw, be welded with lower brace on described hollow screw top, on described lower brace, offer the centre bore corresponding with the through hole of described hollow screw;
Perpendicular to the columniform horizontally-guided bar of described upper transverse reinforcement, the centre position, bottom of described horizontally-guided bar is welded with the core bar in the through hole that inserts described hollow screw, on described core bar, be welded with brace, described upper brace and described lower brace plane contact, and described upper brace is less than described lower brace, the periphery of described upper brace and described lower brace are welded and fixed.
As the preferred technical scheme of one, described supporting steel bar comprises upper transverse reinforcement, a longitudinal reinforcement and a lower transverse reinforcement.
As the preferred technical scheme of one, described lower brace is circular, and described upper brace is square.
As the preferred technical scheme of one, described horizontally-guided shank diameter is 10mm～14mm.
Adopt after technique scheme, the beneficial effects of the utility model are: use levelling device of the present utility model, supporting steel bar is in a row arranged, spacing is at 1 meter～2 meters, after floor bar colligation completes, in the nut of two ends of upper transverse reinforcement, insert hollow screw, then the core bar on horizontally-guided bar is inserted to hollow screw, adjusting horizontally-guided bar makes it substantially vertical with upper transverse reinforcement, upper brace on core bar falls to contacting with the lower brace in hollow screw, on, arranging of lower brace can make horizontally-guided bar remain level, adjust the height of hollow screw, and the instrument such as usage level instrument is monitored at any time, finally make all horizontally-guided masthead absolute altitudes identical, finally again adjusting each horizontally-guided bar makes it vertical with upper transverse reinforcement, then the periphery of upper brace and lower brace are welded and fixed.After concreting completes, when the floating surface layer of floating rule, make floating rule along the operation of horizontally-guided bar, can guarantee like this absolute altitude and the planeness of surface layer.To sum up, the utility model is skillfully constructed simple in structure, easy to implement and cheap, has realized the effect that smooth degree of layer is accurately controlled.
