Description
Technical field
The present invention relates to the rebar connecting technology fields of assembled architecture field more particularly to one kind to smear the connection of cream formula reinforcing bar
Component, and it is applied particularly to the connection method of PC component assembly.
Background technique
In engineering construction field, what China's assembled architecture generallyd use at present is sleeve grouting interconnection technique.Grouting set
Cylinder is born in the invention sixties in last century in the U.S. by Zhan Shuxian more than Chinese American, continues to use by the application and improving of over half a century
So far.Sleeve be in the milk interconnection technique, working principle exactly by metal sleeve cover two docking it is end reinforced, then pass through injected hole
Fill cement based sizing in toward sleeve, reinforcing bar be fixed with anchor after slurry solidification, the cement based sizing after solidification as reinforcing bar and
Shearing resistance material between barrel and form the effective connector of grout sleeve.Though repeatedly being improved afterwards, retain its primitive technology side always
The grouting basic characteristics of case, the change of minor details could not eliminate its defect from the root.The deficiency and defect of the technology are specific
Show following aspects: 1., grouting material waste it is serious, corresponding assembly cost increases.By taking PC shear wall as an example, either adopt
It is still in the milk in a point storehouse with connection grouting, slurry needs first to flow into the gap under PC wall from inlet pipe, fills behind gap used in bottom again
Upper fill backward expires the gap of sleeve lining and reinforcing bar, then flows out from grout outlet, at last the end of a grouting process.It is present in sleeve
Effective slurry between reinforcing bar gap, the 10% of practical deficiency grouting amount, effective rate of utilization is low, and waste is serious.2., slurry phase
It is lower to intensity, cause the anchorage length of sleeve and reinforcing bar relatively long.The grouting is as its name suggests liquid fluidity,
And liquid source is water.By the common knowledge of the industry it is found that the size of amount of water is to determine in the case where composition material is given
Determine the major parameter of the physical and mechanical properties such as cement base products intensity, durability.When watering quantity is more than the hydration institute of cement
After the Optimum needed, the intensity of cement base products declines ratio linear with the increase of watering quantity.The prior art
Grouting material used in grout sleeve, because the ratio of mud for needing to cause grouting material of high fluidity is excessively high, the far super cement of water content
Needed for hydration, peak-peak is not achieved so as to cause the intensity for becoming anchoring material after solidification, it can only be to lengthen casing and steel
The anchorage length of muscle is made up.By diameter 20mm screw-thread steel it is several be connected form for, binding reinforcement connection is related
Technical standard is described further: a, flash butt welding connection: because being that interfacial molecular is mutually fitting to connection, " anchoring " length is almost
Zero；B, extrusion socket joint: single-ended reinforced bar sleeve anchorage length 60mm；C, sleeve grouting connection: single-ended reinforced bar sleeve anchoring length
Spend 160mm.The connection or anchorage length of reinforcing bar are determined premised on its constraint condition or connection type, different companies
Mode is connect, anchorage length difference is obvious.3., grouting plumpness leave a question open, there are security risks.Due to grout sleeve be it is closed,
By Grouting Pipe slip casting inwards, by grout outlet plasma discharge, but the true grouting situation in cylinder, floor and barrel can not be observed visually
Corner be easy to choke with resentment to form cavity；Although into and out of slurry mouth after filling all blocking sealing, when sleeve vertically connects like
The back-off cup for filling with water, under the gravity of liquid grouting material, it is also possible that other for flowing to PC member bottom section do not fill
Solid horn is fallen, and causes the cavity hidden danger of sleeve inner.Sleeve is in the milk interconnection technique in addition to insufficient and defect described above, and there is also works
Many problems such as the pre-buried trouble of factory, construction site installation centering difficulty.Therefore, it researches and develops economical and practical, safe and reliable, quick for installation
Splice technical solution be the industry the task of top priority.
Summary of the invention
The technical problem to be solved in the present invention is to provide one kind to smear cream formula reinforcing bar connection component, and this connection component can be effective
The grouting material waste for avoiding above-mentioned connector shortens anchorage length of steel bar or improves anchoring strength, and applies this connection group
The specific method of part solution PC component assembly connection.
In order to solve the above technical problems, the technical scheme of the present invention is realized as follows: paste anchoring mainly can be applied by inner cavity
The variable cross-section composite sleeve 1 of material, mating taper cuff 2 are constituted；The variable cross-section composite sleeve 1 is by two semicircular cylinder make-up groups
The internal diameter of conjunction is equal everywhere, outer diameter is from centre to the variable diameter assembled tube of both ends gradual change undergauge；If 1 internal chamber wall of combined sleeve has
Arterial highway ring rib or annular groove 1.1, inner cavity chamber can accommodate paste anchoring 3 and can sweep along two docking spiral ends 4；The taper
Cuff 2 is that the outer diameter variable cross-section of a pair of of internal diameter and combined sleeve 1 matches and can be inserted in respectively from the both ends of combined sleeve 1
The variable cross-section round tube of fastening, the modular sleeve of Chang Du≤1/2 1.
Grouting material used in existing general technology grout sleeve is all with cement, high-strength compared with present invention anchoring material
The dry blend for spending the compositions such as fine aggregate, concrete admixture and micro-expanding agent, adds water and stirs at the construction field (site).Difference exists
In the size of amount of water.But it is as follows to distinguish effect: 1., saving material.Paste anchoring material watering quantity of the invention is small, close to
Solid-state only need to uniformly daub into 1.1~1.2 times of anchoring material of actual amount, without grouting material in semicircular cylinder cavity groove
High fluidity, without fill feed and exhaust tube, PC component with dock slip casting path clearance between supporting surface, sleeve gap and cause big
Measure the waste of grouting material.2., avoid cavity dead angle.It is more when semicircular cylinder after uniformly smearing cream is fastened on steel bar end by the present invention
Remaining creme is squeezed out from opposite joint, and the compactness that visually whole can be observed or perceive anchoring and expect is avoided because grouting is brought
Harm of choking with resentment.3., improve anchoring material intensity, shorten the length of anchoring sleeve.Because the moisture content of present invention anchoring material is reasonable
Section, hence it is evident that higher than the grouting material intensity of good fluidity, corresponding shearing strength, bond stress are also high.So combined sleeve with
The anchorage length of docking reinforcing bar can accordingly shorten, alternatively, original anchorage length referring to grout sleeve is constant, strength of joint will
Improve a credit rating, more conducively antidetonation.
Further, the combined sleeve inner cavity can also be that the thin ends and thick middle variable cross-section composite in waist drum shape is oval
Pipe.
If not considering, the expansion of the compensatory micro-expanding agent added due to the cement base of anchoring material is easy to the characteristic of drying shrinkage is made
With under reinforcing bar responsive to axial force, anchoring material and straight tube set tube wall interface, anchoring expect not produce between rebar surface interface
Raw radial pressure.By friction formula it is found that frictional force=pressure × coefficient of friction.When pressure is null, frictional force is certainly
It is so not present, existing is to anchor material to the screw thread and reinforcing bar rough surface and pipe of the bond stress of reinforcing bar and anchoring material and reinforcing bar
The ring rib of wall and the mechanical snap power of tube wall rough surface.When the inner cavity tube wall of sleeve is contracted from centre to both ends diameter, in two osculums
Respectively when outside thin ends and thick middle swelling-waist shape, anchoring material tightly bonds docking screw-thread steel end, docks steel two
Muscle is in axial under tension state, and the circumferential inclined-plane of tube wall will expect anchoring to generate inclined-plane resistance, a part point of inclined-plane resistance
Solution obtains a part of frictional force multiplied by coefficient of friction at the radial compression power for being directed toward rebar surface.Dock it is end reinforced
On the basis of obtaining original bond stress and mechanical snap power, since the inclined-plane of sleeve wall changes, and rubbing for superposition is obtained
Power is wiped, to keep steel reinforcement abutting joints connector stronger.
Further, the ends of the two docking spiral can also be cased with the interior of outer diameter and place sleeve portion respectively
The consistent limiting gasket of diameter.The consistent limit of internal diameter of outer diameter and place sleeve portion is cased in the end of two docking spirals
Washer, effect, one to be to maintain position of the steel bar end in casing placed in the middle, second is that during installing casing collar
Keep positional stability of the steel bar end in casing constant.PC component stretches out external docking reinforcing bar in demoulding, transport, lifting
In the process, can inevitably collide with deforming displacement, and after the installation of PC component is in place, splice one by one, two docking are end reinforced may not
Concentric axis can be in.During fastening two halves round buss fastening hoop, the port of sleeve rectifies a deviation reinforcing bar poly- by force
In, the end for docking reinforcing bar will have the small size amplitude of oscillation of reforming as free end, it is possible to the anchoring filling agent of plasticity be stirred, to lead
It causes to generate between the filler lotion and reinforcing bar at the steel bar end amplitude of oscillation direction of displacement back side hollow, influences the close of filler lotion in casing cavity
It solidity and wraps to reinforcing bar, limiting gasket plays the limit to reinforcing bar as bracket and avoids reinforcing bar agitation anchoring material cream
Firm effect.
Further, the anchoring material is cement base high-strength mortar, and mortar aggregate ingredient can be steel cuttings or include
Steel cuttings compares with existing grouting material, can greatly improve mortar strength.Because the flow behavior of grouting material should not add density
The steel cuttings ingredient that height easily precipitates.
Further, the anchoring material can also be that epoxy group aggregate mortar, mortar aggregate ingredient can be steel cuttings or packet
Contain steel cuttings.Another selection of the epoxy group mortar as anchoring material, it is identical with cement-based mortar in role of the present invention,
But its mechanical property is more than cement-based mortar, and quick solidifying is suitable for and tries to meet the deadline for the project, Accelerating The Construction speed；Mortar aggregate ingredient is steel
It considers to be worth doing or includes steel cuttings, mortar strength can be greatly improved.
Further, also buckle has the section that can fasten docking screw-thread steel on the edge of the end semi-ring rib of the semicircular cylinder
Be in U-shape rubber closed-loop.The section being snapped on semi-ring rib edge is in U-shape rubber closed-loop, can fasten docking screw-thread steel, make
