Abstract

The invention discloses an anti-floating structure and a method for a cast-in-situ concrete GBF (glass basalt fiber) hollow floor slab during construction period. The method for manufacturing the anti-floating structure comprises the following steps: mounting a formwork on a formwork support; arranging a GBF thin-walled tube and punching on the formwork according to longitudinal and transverse spacing intervals based on the position of the GBF thin-walled tube; mounting the GBF thin-walled tube by using a steel bar for binding; mounting a PVC (polyvinyl chloride) sleeve, a hook-shaped bolt and a steel padding plate, tightly hooking the hook-shaped bolt with the formwork support, tightly pressing the steel padding plate and the anti-floating steel bar through a nut, casting concrete in situ after checking and accepting various items, further completing the casting of the concrete and achieving initial setting; and detaching the steel padding plate and the hook-shaped bolt, and using mortar to tamp, fill and level up a bolt hole. By adopting the structure and the construction method thereof, upward floating of the GBF thin-walled tube during casting of the concrete in situ can be effectively solved, after the formwork is detached, an exposed iron wire head does not need to be treated in the later period, a large number of iron wires can be saved and the phenomenon of being prone to re-rusting after the construction of a coating can be avoided.

Description

Be used for cast-in-situ concrete GBF cassette ceiling float Structure and method thereof
 
Technical field
The present invention relates to a kind of float Structure and method that is used for during the cast-in-situ concrete GBF cassette ceiling structure construction, belong to technical field of building construction.
Background technology
In recent years, domestic in the multilayer and highrise building of large space, cast-in-situ concrete GBF cassette ceiling appears, and be a kind of floor of forming by dark beam and non-Drawing-Core cassette ceiling; Dark beam and floor uniform thickness, thus the use height in space increased, reduce the deadweight of structure, do not adopting under the prestressed situation, make structure can satisfy the requirement of large bay, large span, reach the purpose that reduces cost, be specially adapted to the large bay public building.
This kind cast-in-situ concrete GBF cassette ceiling structure is in construction period, because concrete flowing, cause the GBF light-wall pipe come-up of cast-in-situ concrete GBF cassette ceiling, thereby cause slab thickness unequal, it is a big technical barrier in this field always, when head it off, in the past iron wire binding GBF light-wall pipe bodys that adopt more, and it is fixing that iron wire is passed the binding of template and lower bracket, use iron wire quantity bigger, a large amount of iron wires are kept somewhere in the structure after the concrete setting, post-processed exposes the iron wire head and drops into the expense height, is prone to behind coating application simultaneously and returns the rust phenomenon.On August 5th, 2009, disclosed application number was that the application for a patent for invention file of 200910119142.3 " a kind of anti-floating construction method of cast-in-place concrete hollow building roof " has disclosed a kind of job practices that adopts steel bar rod and bearing plate to form, has the advantage that construction is simple, ensure the quality of products, but behind stripping, steel bar rod still is retained in the structure, have the extensive work of post-processed equally, and behind coating application, occur return the rust phenomenon.
Summary of the invention
The technical problem to be solved in the present invention is the problem of GBF light-wall pipe come-up in the cast-in-situ concrete GBF cassette ceiling structure construction procedure, and expends auxilliary materials such as manually a large amount of and iron wire in the tradition construction.
For solving this technical problem, the invention provides a kind of structure and job practices that solves cast-in-situ concrete GBF cassette ceiling construction period anti-floating.
The described float Structure that is used for cast-in-situ concrete GBF cassette ceiling, comprise the anti-floating reinforcing bar, lower floor's reinforcing bar, template, falsework, the GBF light-wall pipe, described GBF light-wall pipe is between anti-floating reinforcing bar and lower floor's reinforcing bar, vertically have two place's horizontally set anti-floating reinforcing bars at least at every section GBF light-wall pipe, this GBF light-wall pipe, anti-floating reinforcing bar and lower floor's steel bar overall are positioned on the template, this template is positioned on the falsework, the present invention also comprises hook bolt, the steel backing plate, sleeve pipe and nut, one end of described hook bolt has crotch, the other end is threaded, and its length is longer than the thickness of the cast-in-situ concrete GBF of institute cassette ceiling; Gap on the described template between the GBF light-wall pipe is provided with a plurality of open-works, and the GBF light-wall pipe 9 in the horizontal interval at least of described open-work is located at the below of anti-floating reinforcing bar, and the diameter of its open-work is slightly less than the external diameter of described sleeve pipe; Described sleeve pipe places on the template, aligns with open-work, and hook bolt passes open-work and sleeve pipe, and its underpart and falsework collude tightly, and top compresses by steel backing plate and anti-floating reinforcing bar with nut.
The described anti-float method that is used for cast-in-situ concrete GBF cassette ceiling comprises:
