Description
Technical field
The utility model relates to a kind of hollow floor core model more particularly to a kind of band Self Drilling Screws bar anti-floating installation components
Hollow floor core model.
Background technique
In building field, as large-span concrete structure is increasing, more and more floors use hollow floor knot
Structure technology replaces part concrete with lightweight filler substantially and will not influence the stress performance of structure, but can be significantly
Mitigate the self weight of structure；According to current " cast-in-place concrete hollow building roof technical regulation " JGJ/T268-2012, according to filling
The land-fill method of material is different, is divided into built-in obturator cored slab, the exposed obturator cored slab of single side and two-sided exposed obturator
Three kinds of structure types of cored slab, two-sided exposed obturator cored slab is because concrete girt strip is free of any edge of a wing, the rigidity of floor
Small and use is by very big limit value；Built-in obturator cored slab includes upper lower flange, and Equivalent Mechanical section is i shaped cross section,
For the exposed obturator cored slab of single side containing only top flange, Equivalent Mechanical section is T-type section, when slab thickness is identical, I-shaped
Type section strengthening floor slab rigidity is about twice of T-type section, therefore i shaped cross section cored slab has best mechanical property；
For save cost, construction it is more convenient, I it is proposed that " cast-in-situ reinforced concrete hollow floor core model,
Hollow floor " (application number CN201720840914.8), according to Archimedes' principle, in any built-in obturator cored slab
In, packing material must generate biggish buoyancy when casting concrete, in order to overcome buoyancy, to take in construction and much arrange
Apply carry out anti-floating, in addition to it is expensive, take a lot of work, be time-consuming other than, it is also bigger to the damage of board bottom template, once and certain road technical measures not
Cause packing material to float in place, very big security risk will be brought to structure, in order to overcome the buoyancy of packing material, applicant
The core model is improved, Self Drilling Screws anti-floating installation component is increased.
Summary of the invention
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of band Self Drilling Screws bar anti-floating installation component
Hollow floor core model, construction speed is greatly improved on process efficiency, especially product anti-floating and displacement on not only
Save artificial and auxiliary material, it is also significantly easy in construction technology.
To achieve the above object, the technical solution of the utility model is: a kind of band Self Drilling Screws bar anti-floating installation structure
The hollow floor core model of part, including core model ontology, are placed in the isolating bar of core model body upper surface, by the exposed table of the isolating bar
The fiberglass gridding cloth and mixed coated on the cement glue on fiberglass gridding cloth that face and core model body surface wrap up
Object, it is characterised in that: the Self Drilling Screws bar with anti-floating gasket across core model ontology, institute are vertically installed on the core model ontology
Core model body bottom portion is stated equipped with support leg.
The support leg is isosceles triangle ABC plastic support foot, and a height of foot pad is at least 50 millimeters, at least 3.
The diameter of the Self Drilling Screws bar is 4-5 millimeters, at least 3.
The diameter of the anti-floating gasket is 50-60 millimeters and matches with Self Drilling Screws bar.
Rectangular or cylindrical or polygon made of the core model ontology light flame-retardant foam or light foaming cement binder
The core model ontology of shape cylinder.
The isolating bar is steel pipe or batten or plastic tube.
The beneficial effects of the utility model are: the utility model greatly improves construction speed on process efficiency, especially
It is that artificial and auxiliary material is not only saved in product anti-floating and displacement, also significantly easy in construction technology, anti-floating compared with prior art,
Template punching is not needed, reinforcing bar was laid, tie wire places cushion block, and upper and lower two working faces of template will artificial treatment；
The utility model anti-floating only needs the working face on product to implement.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the utility model spare and accessory parts structural schematic diagram；
Fig. 3 is the utility model use state diagram；
In figure: 1-core model ontology, 2-isolating bars, 3-fiberglass gridding cloths, 4 cement gel water complexs, 8-supports

Specific embodiment
The utility model and its specific embodiment are described in further detail with reference to the accompanying drawing.
Referring to Fig. 1-2, the utility model includes core model ontology 1, is placed in the isolating bar 2 of core model body upper surface, will be described
The fiberglass gridding cloth 3 and be coated on fiberglass gridding cloth that 2 exposed surface of isolating bar and 1 surface of core model ontology are wrapped up
Cement glue mixture 4, it is characterised in that: the band anti-floating pad across core model ontology is vertically installed on the core model ontology 1
The Self Drilling Screws bar 9 of piece 10,1 bottom of core model ontology are equipped with support leg 8.
The support leg 8 is isosceles triangle ABC plastic support foot, and a height of foot pad is at least 50 millimeters, at least 3.
The diameter of the Self Drilling Screws bar 9 is 4-5 millimeters, at least 3.
The diameter of the anti-floating gasket 10 is 50-60 millimeters and matches with Self Drilling Screws bar 9.
