Description
Technical field
The present invention relates to a kind of method of attachment of reinforcing bar and realize that the hand-hydraulic of this method clamps.
Background technology
At present in the splice of architectural engineering connects, mainly be to adopt cold extrusion to connect and be threaded, there is following problem in it: 1, the cold extrusion method of attachment is that two reinforcing bars that needs connect are set in the steel sleeve head to head, compression sleeve then, make sleeve and reinforcing bar generation deformation, link together by frictional force, this method of attachment need be adopted tube wall thicker (10 millimeter) usually, the sleeve of longer dimension (120～240 millimeters), not only rolled steel dosage is bigger, and needing to be equipped with the big heavy dedicated hydraulic machinery of volume, onsite moving is very inconvenient; In the process of compression sleeve, the power that applies is little in addition, and bonding strength is not enough, and the power that applies is big, and casing strength is not enough, and therefore this method of attachment is eliminated gradually.2, threaded connection method needs will connect with sleeve earlier to process internal thread, and the steel bar end that will need at the construction field (site) again to connect processes external screw thread, during connection, respectively two reinforcing bars is revolved in the internal thread that is located at sleeve head to head.Though this method is slightly littler than cold extrusion method rolled steel dosage, many cover machining apparatus need be set at the scene, and need to be equipped with skilled machined personnel, and reinforcing bar to carry back and forth at processing site, the amount of labour is big, the cost height.
Summary of the invention
At the problems referred to above, the purpose of this invention is to provide a kind of reinforcing bar and be connected firmly, site operation is convenient, saves steel, the connecting method for reinforcing bars that cost is low and realize the hand-hydraulic pincers of this method.
For achieving the above object, the present invention takes following technical scheme: a kind of method of attachment of reinforcing bar is characterized in that: it may further comprise the steps: (1) mixes the paste adhesive of two kinds of different components, and is standby; (2) cleaning is carried out in the junction of steel bar end; (3) in sleeve, smear described standby adhesive respectively with two reinforcing bar junctions, and with the junction of jacket casing at described two reinforcing bars; (4) with the hand-hydraulic pincers described sleeve is carried out the segmentation extruding, its distortion is embedded between the cross rib of described two reinforcing bars, and described two reinforcing bars and described sleeve are bonded together by adhesive.
Described hand-hydraulic pincers are consistent with the cross rib incline direction on the described reinforcing bar to the position of described sleeve extruding.
Be to realize said method, specialized designs of the present invention a kind of hand-hydraulic pincers, it is characterized in that it comprises: an oil cylinder; One valve piston, its vertical being arranged in the described oil cylinder; One big piston, it is horizontally installed in the described oil cylinder, and described big piston is driven by described valve piston, by spring reset; Two stands, it is arranged on the oil cylinder of described big piston one end; Two slide blocks, it is slidingly installed between the described two stands, and described two slide blocks are relatively set with extrusion mouth, and are fixedly connected on the outer end of described big piston near inboard described slide block; One pin, it is located in the pin hole of described two stands; One handle, one end are connected described oil cylinder bottom, and the other end is used to hold; One depression bar, one end are hinged on described oil cylinder top, but other end manual squeezing is provided with an external part that is connected with described valve piston near described pin joint.
Extrusion mouth on described two slide blocks is the inclination fin that is oppositely arranged in the described two slide block concave arcs, and the angle of inclination of described inclination fin is corresponding with the angle of inclination of the circumferential symmetrically arranged cross rib of reinforcing bar.
The described two relative fins segment distance that staggers.
Angle that described fin tilts and described slide block vertical is 35 ° of angles.
The present invention is owing to take above technical scheme, it has the following advantages: 1, the invention provides the new method that a kind of reinforcing bar connects, it is when carrying out crimp to sleeve, adopt chemical adhesive to carry out bonding, it compared with prior art, save steel, reduce processing capacity, execute-in-place is very convenient.2, the present invention is owing to adopt the connected mode of bonding two kinds of power of sleeve deformation and adhesive simultaneously, therefore compared with prior art, the sleeve wall thickness that the present invention uses is thinner, and length is shorter, not only save great deal of steel, and can just can operate with the lower hand-operated tools of extruding force; Owing to needn't use heavy hydraulic machinery and on-the-spot machining tool, therefore can improve joint efficiency simultaneously, shorten construction period, save the energy and manpower.3, the present invention is owing to use adhesive, be extruded in the process of distortion at sleeve, adhesive can fill up the gap between sleeve and the reinforcing bar, the feasible joint that originally has been connected firmly with mechanical means behind adhesive solidification, about enhancing more than 35% of having got back connects power, thereby the safety coefficient that has improved construction quality, particularly Important Project effectively can obtain sound assurance.4, for realizing said method, the present invention has designed a kind of simple and practical hand-hydraulic pincers especially, it can promote two slide block compression sleeves by handle and depression bar control hydraulic piston, the deformation place of sleeve is clamp-oned between the cross rib of two reinforcing bars, chemical adhesive power in addition, can finish the connection of splice under situation about need not exert great efforts, this mode of operation and fastening means are in short of electricity even do not have electric occasion, more can fully show its superiority.5, the present invention is owing to a side that the operating side of handle and depression bar all is arranged on squeezed joint, and therefore operation is very light, and whole stressed rationally even.6, the present invention is owing to consider that original cross rib is provided with direction on the reinforcing bar, and a reinforcing bar circumferentially has stagger a mutually cross rib of certain distance of two rows, therefore be provided with on two slide blocks of hydraulic tongs with reinforcing bar on the consistent fin of cross rib incline direction, and two relative fins some distances that staggers, thereby deformation place is fallen between the cross rib of reinforcing bar exactly, and this is that prior art can not be compared.The present invention does not need machining screw, can save process equipment, processing place and human resources, and it can be widely used in the connection of splice of various construction sites.
