Vertical bars at the corner of domatic isolated footing to be poured, and be centered around the rectangular of setting on the outside of the foundation columns joint bar and determine
Position stirrup, diagonal bar is connected between the corner and the top of the corresponding vertical bars of the positioning stirrup；The top of the vertical bars,
It is consistent to position the vertical distance of stirrup and diagonal bar to the forming surface of domatic isolated footing to be poured, and is all higher than minimal protection layer
Thickness.
Using said structure so that the diagonal bar being connected between the corner of positioning stirrup and corresponding vertical bars is independent along domatic
The domatic broken line direction on basis is set.Again due to the top of vertical bars, positioning stirrup and diagonal bar to domatic isolated footing to be poured
Forming surface vertical distance it is consistent, and be all higher than minimal protection thickness degree.So, when casting concrete, Gong Renke
To be controlled by diagonal bar to the thickness of concrete, the difficulty of concreting is advantageously reduced.Moreover, there is the auxiliary of diagonal bar
Help so that requirement of the concrete pouring construction to worker's technical merit is relatively low, is advantageous to improve the quality of concreting
And uniformity；Ensure domatic isolated footing molding effect, improve domatic isolated footing pouring molding speed, reduce domatic independence base
Plinth pours labor intensity.Said structure is simple, and installation operation is convenient.
Further, the vertical bars are implanted into the blinding layer, or are welded on the basic net sheet.
So, the installation of vertical bars can be made easier, installation is more reliable.
Further, multiple brace rods are additionally provided between the diagonal bar and the basic net sheet.
So, the intensity of diagonal bar can be increased, when avoiding diagonal bar long, middle part can bend, and influence the mixed of later stage
Coagulate native pouring quality.
Further, the forming surface of the top of the vertical bars, positioning stirrup and diagonal bar to domatic isolated footing to be poured
Vertical distance be 20~30mm.
So, in the case where meeting the requirement of minimal protection thickness degree, reduce the distance as far as possible, be easy to worker constructing
When can preferably control the Forming Quality of concreting.
Further, multiple reinforcing hoops for being used to reinforce the foundation columns joint bar are additionally provided with the foundation columns joint bar
Muscle.
So, the intensity of foundation columns joint bar can be increased, improve the Forming Quality and intensity of domatic isolated footing.
Further, the stirrup of reinforcing includes the embedded division reinforcing stirrup in domatic isolated footing, positioned at domatic
The encrypted area of the top area of isolated footing reinforces stirrup, and reinforces stirrup positioned at the non-encrypted area on foundation columns joint bar top.
In summary, the utility model, which has, enables to requirement of the concrete pouring construction to worker's technical merit relative
It is relatively low, be advantageous to improve the quality and uniformity of concreting；Ensure domatic isolated footing molding effect, it is independent to improve domatic
Basic pouring molding speed, reduce the advantages that domatic isolated footing pours labor intensity.

Embodiment：
1st, reinforcement fabrication
The surface of reinforcing bar should be clean, and oil stain, the outer skin that paints dirt and can be peeled off when pounding with a hammer, iron rust etc. should be clear before use
Except clean.Conscientiously it is familiar with drawing before blanking, establishment material table, should avoids during fracture with short dipstick metering length material, preventing from producing in amount material
Raw cumulative errors.In cutting-off process, such as find that reinforcing bar has splitting, drop-head or serious elbow to cut off.Vertical bars termination
Processing, preferably using emery wheel cuts, electric arc must not be used to cut, port surface should smooth out, and notching edge must not have crackle, root face and lack
Rib.Positioning stirrup is processed into closed ring type and constructs its structure, and reinforcing bar preferably uses two-sided overlap welding or single welding, the lap of splice >=5d
Or >=10d, joint welding thickness >=0.3d, weld width >=0.8d；In construction, reinforcement welding answers pre-bending, to ensure that two connect
On an axis, 2 points are fixed head, and tack weld should should start from more than overlapping end 20mm, striking in overlap joint one end, receive arc
Should be on overlap joint termination, arc crater fills up.First layer weld seam should have enough fusion penetrations, main weld and tack weld, particularly fixed
The top and terminal of position weld seam, it should fuse good.
2nd, reinforcement installation
Positioning stirrup is welded in outside basic coupling beam longitudinal reinforcement top or foundation columns joint bar；Vertical bars are implanted into blinding layer four
At angle or it is welded in basic net sheet muscle edge；Diagonal bar prolongs the knuckle line arrangement at domatic basis four sides, top and bottom, is respectively welded
In positioning stirrup angle point bending place and vertical bars top of supply line, apparent distance length increase in middle part is with diameter support reinforcing bar and welds jail
Gu.Above reinforcement welding technique uses arc welding, and before welding, the scale at solder joint should be removed totally, in welding process and
When scarfing cinder, face of weld is smooth, and weld seam is attractive in appearance.
3rd, the most suitable slump of concrete is determined
The slump of concrete should according to structure section, reinforcing bar content, transportation range, pour mode, means of transportation, vibrate
The conditional decision such as ability and weather, shelving isolated footing concrete slump preferably select 160mm ± 20mm.The test side of slump
Method：With the slump bucket that a 100mm suitable for reading, lower mouth 200mm, high 300mm are horn-like, consolidate after penetration concrete, then pull out
Bucket is played, concrete is because deadweight produces slump phenomenon, with bucket height（300mm）The height of concrete peak after slump is subtracted, if
Difference is 160mm, then slump is 160.Concrete supply side should have strict quality assurance system, and deliverability should meet company
The requirement of continuous pumping.The performance of concrete should still meet existing national standards in addition to it should meet design requirement《Ready-mixed concrete》
GB/T 14902 pertinent regulations.
4th, concreting
It should be layered and be carried out continuously during casting concrete, placement layer by layer thickness cannot be greater than 300mm.Pour for the first time to basis
Poured for the second time again behind footing position, about 0.5h.Period should often observe template and positioning stirrup whether there is and walks about, shifts feelings
Condition, when discovery has deformation, walks about or shift, stop pouring immediately, and amendment and reinforcing template in time, then it is further continued for pouring
Build.In concreting process, when concrete loses flowability and possesses certain plastic, using the chi side more than key dimension,
Prolong positioning stirrup to strike off and make basic moulding；Before concrete initial set, then prolong basic four sides with wooden float and rub flat receipts face with the hands, and ensure
Minimal protective cover thickness.
5th, concrete curing
The concrete poured, should be covered in 12h rear films or water seasoning, normal temperature maintenance are no less than 7d.If special messenger
Check and implement, prevent from, due to conserving not in time, causing concrete surface crack.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not using the utility model as limitation
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
