Description
Technical field
It the utility model is related to building floor and pour field, and in particular to a kind of concreting floor bar skeleton is spacing
And slab thickness accurately can be controlled pours built-in fitting.
Background technology
With developing rapidly for construction industry, skyscraper is more and more, government, designing unit, construction unit, unit in charge of construction
Deng higher requirement is all proposed to project delivery method, related appraisal standards and system are formulated, have been increased to engineering construction matter
The inspection of amount, especially concreting floor；Double steel bar grid composition is all designed with concreting floor
Framework of steel reinforcement, concreting floor plan requirement in, framework of steel reinforcement at the middle and upper levels bar-mat reinforcement and lower floor's bar-mat reinforcement away from floor
There is close dimensional limitation the distance between upper surface and soffit, as shown in figure 1, in figure, floor upper surface is 11, floor
Bottom surface is 12, top mat 13, lower floor's bar-mat reinforcement 14, and the thickness of whole floor is H, i.e. floor upper surface 11 and soffit
The distance between 12 be H, and the center of top mat 13 to the vertical range between floor upper surface 11 is h1, top mat
Vertical range between 13 and the center of lower floor's bar-mat reinforcement 14 is h2, the center of lower floor's bar-mat reinforcement 14 to hanging down between soffit 12
Straight distance is h3, and H, h1, h2 and h3 are technical parameters crucial in concrete floor slab placement, during concrete floor slab placement, it is necessary to strict control
Above-mentioned four big technical parameters are made, otherwise can not only influence the bearing strength of floor, the floor safety coefficient directly reduced, Er Qiehui
The flatness of floor upper surface is influenceed, increases the thickness of levelling layer 16 in the future, the dosage of concrete mortar, again meeting should be increased
Increase cost of labor, can also reduce the actual floor height of floor.It is typically first in bar frame in the construction of existing concrete floor slab placement
Lower section carries out formwork, lays cast-in-situ template 15, it is ensured that the flatness of the upper surface of cast-in-situ template 15, then in cast-in-situ template 15
Steel bar horse-shaped bench is furnished on upper surface, holds top mat, according to this supports whole framework of steel reinforcement, then with regard to carrying out coagulation
Native pouring construction, existing reinforced bar support split heads are divided into two kinds：The first is Madeng ' made up of plastic；Second made of cement mortar
Square stool block type split heads, this equal square stool shape of two kinds of split heads, stool surface have four legs, and cross breach is formed between four legs, with
Lower floor's bar-mat reinforcement is avoided, by the stool surface support top mat of split heads；The finished product of this two kinds of steel bar horse-shaped benchs in the fabrication process closes
Lattice rate is low, and in actual use, support strength is low, legs and feet compression breakage rate is high, in practice it has proved that with this two kinds of steel bar horse-shaped benchs
It all can not effectively control tetra- big key of H, h1, h2 and h3 in concrete floor slab placement to hold art parameter, be used in concrete floor casting process
Above-mentioned two kinds of steel bar horse-shaped benchs can not accurately control the accurate position of top mat, lower floor's bar-mat reinforcement in concreting floor
Put, also the gross thickness of different control concrete floors, the flatness of concrete floor upper surface less can guarantee that, Shen of tracing it to its cause
Ask someone to think：
Although existing Madeng ' made up of plastic or concrete split heads stool surface can hold the top mat in framework of steel reinforcement, horse
Four legs of stool stool surface lower end are all shelved on the upper surface of cast-in-situ template 15, between the two without fixed connection structure, mixed
Coagulate in native casting cycle, because concrete is mud-rock flow shape before curing, injects in concrete, vibrate, bury real casting process
In, the concrete of mud-rock flow shape can move up by whole framework of steel reinforcement and by bracketing, cause between framework of steel reinforcement and cast-in-situ template 15
Away from increase, i.e. the distance between lower floor's bar-mat reinforcement 14 and soffit 12 h3 increases, top mat 13 arrives floor upper surface
11 distance diminishes, simultaneously as the concrete of mud-rock flow shape, in injecting, vibrate, burying real casting process, concrete is to upper strata
The upward thrust of bar-mat reinforcement 13 and lower floor bar-mat reinforcement 14 is different, thus necessarily lead between the two away from increase, i.e. h2 increases；Due to
There is no levelling benchmark in upper surface during concrete floor slab placement, therefore, the flatness for pouring thickness and upper surface of floor all can only be according to
Controlled by workmen's manual operation, so, not only floor pours thickness and can not accurately controlled, and floor upper surface is flat
Whole degree cannot guarantee that floor gap can not be determined precisely away from bulk, when carrying out ground levelling, mortar increase,
It is big that manual operations includes flat workload, and labor intensity is high, adds construction cost.

Property marine glue；When in use, the three-dimensional leg of the controller is separately leaned against naturally and control is vertically erected on negative reinforcement side
Device, lock claw bar with two negative reinforcements and grab negative reinforcement (being equal to top mat), with hand steered firmly controller top
It is tight by the two negative reinforcements locking claw bar to be linked with it after the dynamic Bars In Poured Concrete Slab thickness of slab wrench chi mark bolt application certain pressure of plate
Negative reinforcement is held to, tightens by hand after locking extraction bolt applies certain pressure and is tightly pushed up by compensating the effect of bar internal stress
Firmly Bars In Poured Concrete Slab thickness of slab wrench chi mark bolt makes two negative reinforcement locking claw bars tightly hang the position of locking negative reinforcement, goes back
Needing to use sealing-plug to block Bars In Poured Concrete Slab strip thickness control hole prevents concrete from entering.
Applicant has found that the control to thickness of slab in above-mentioned patent relies primarily on Bars In Poured Concrete Slab after carefully analyzing the patent
Thickness of slab wrench chi mark bolt and Bars In Poured Concrete Slab strip thickness control hole, must detect by an unaided eye after the completion of pouring on each strip thickness control device
Bars In Poured Concrete Slab thickness of slab wrench chi mark bolt and Bars In Poured Concrete Slab strip thickness control hole, because the surface area of floor is very big, caused by visually observing by mistake
Difference is larger, and flatness is very poor, influences the quality of floor；In that patent, caught by two negative reinforcements locking claw bars negative
Moment at support, negative reinforcement is then locked by the transmission of other machinery structural capacity, it is curved can to realize that strip thickness control device is born relatively
Square reinforcing bar is vertically arranged and fastened with the jail of negative reinforcement, because controller is fixed on framework of steel reinforcement, therefore still
In the presence of caused technological deficiency is synchronously moved up with framework of steel reinforcement, in casting process, the strip thickness control device can drive hogging moment
The overall asynchronous floating upwards of reinforcing bar, causes the vertical range between negative reinforcement center and lower floor's bar-mat reinforcement center seriously to lose
Control, greatly influence the structure and quality of floor；The complex installation process of the controller, it is not easy to operate.By above-mentioned analysis,
Although it is plate thickness controller, it can not control the position of framework of steel reinforcement in concreting floor, can not control building
The flatness of plate upper surface, it is larger in the error of control concrete floor slab placement thickness, it can not realize and be precisely controlled, therefore, it can not essence
Really tri- critical technical parameters of h1, h2, h3 of framework of steel reinforcement and floor upper end in the high total degree and floor of control concrete floor
The flatness in face.
