Abstract
The utility model discloses a sleeve wedge block-type reinforcing steel bar connection joint. The sleeve wedge block-type reinforcing steel bar connection joint mainly comprises a sleeve and a wedge block, and is used for two modes of connection of abutting and lapping of reinforcing steel bars. In the abutting of the reinforcing steel bars, the sleeve wedge block-type reinforcing steel bar connection joint consists of a semi-cycle insection sleeve, a wedge block and a conical wedge nail, wherein the semi-cycle insection sleeve is a diagonal insection; a positioning wedge hole is formed in the semi-cycle insection sleeve; and the wedge block is provided with an arc-shaped groove at the position of the wedge hole. The sleeve wedge block-type reinforcing steel bar connection joint is characterized in that: the reinforcing steel bars can be connected tightly without using special equipment and tool when in use; a using method is simple; and the connection strength is high.
Description
Affiliated technical field
The utility model relate to a kind of in building operations the connected mode of reinforcing bar.
Background technology
At present, in building operations, the connected mode of reinforcing bar has multiple, when using thicker reinforcing bar; Be the screw-thread steel of diameter, in order to save material welding commonly used greater than 16mm; Like the submerged arc electroslag pressure welding, with common welding of welding rod or sleeve screwed connection, there are many drawbacks in these connected modes.
1, be to need corresponding apparatus.
2, the operator needs certain technical level.
3, use inconvenience.
4, there is not complete reliable technique to guarantee.
Summary of the invention:
Sleeve Wedge-type reinforcing bar jointing is used for a kind of connected mode at the building operations reinforcing bar, and this connected mode is quick, effective; Just can easily solve the reinforcing bar connectivity problem without particular device, this joint has two kinds of forms: a kind of is the reinforcing bar butt joint, and another kind is bar splicing; In the reinforcing bar butt joint, to form by half-turn groove sleeve, voussoir, cone wedge nail, the half-turn groove is a diagonal pitch; Half-turn groove sleeve is provided with the locating wedge hole, and voussoir has an arc groove in the position in wedge hole.In bar splicing, be provided with light surface sleeve wall sleeve and tooth of synchronous belt voussoir and form, light surface sleeve wall sleeve is provided with intermediate interlayer, voussoir stator.In using the reinforcing bar butt joint, let half-turn groove sleeve and the complete interlock of full-depth tooth line reinforcing bar, add voussoir and fix; The half-turn groove of sleeve and the groove of reinforcing bar mate, and the reinforcing bar of various diameters all has corresponding sleeve, and (joint form that comprises reinforcing bar) groove is used diagonal pitch; Diagonal pitch is exactly that the extension direction of groove becomes certain included angle with the cross section of reinforcing bar, and diagonal pitch comprises screw thread, when the diagonal pitch reinforcing bar is connected with sleeve; Use which head, have selectivity, have only the interlock of groove and sleeve groove direction one to ability; As long as the tune of sleeve or reinforcing bar, let their groove once to passable during use, the characteristics of this connected mode are: drawn the direction groove that certain tensile strength also is provided at reinforcing bar; Each groove is all parallel to each other, and the specification of the width of groove, the degree of depth, groove, line be apart from all equating, when the specification of the wall thickness length of definite sleeve and groove; Select enough wall thickness and length, guarantee to receive when needing pulling force, can not damage at reinforcing bar.
The beneficial effect of the utility model is, make simple, price is low, any diameter reinforcing bar all can connect, and easy to connect, equipment that can be specific and instrument are practiced thrift great deal of steel, bonding strength is big, the junction of reinforcing bar is the same with portion other than connected portion intensity big.

The specific embodiment
The reinforcing bar butt joint form of sleeve Wedge-type reinforcing bar jointing is made up of half-turn groove sleeve, voussoir, cone wedge nail, and the half-turn groove is a diagonal pitch, and half-turn groove sleeve is provided with the locating wedge hole; Voussoir has an arc groove in the position in wedge hole, in reinforcing bar butt joint, referring to Fig. 1, Fig. 2, insert half-turn groove sleeves 2 to full-depth tooth line reinforcing bar 3, lets half-turn sleeve groove 5 and the 4 complete interlocks of reinforcing bar groove; Put into voussoir 9 then,, put into cone wedge nail 7 by locating wedge hole 8 with the urgent voussoir 9 of hammer kind tool; Urgent the getting final product of exerting oneself in bar splicing, is made up of light surface sleeve wall sleeve and tooth of synchronous belt voussoir; Light surface sleeve wall sleeve is provided with intermediate interlayer, voussoir stator, and referring to Fig. 3, groove is a sketch map among the figure; Do not represent actual groove, put into light surface sleeve wall sleeve 17 to reinforcing bar, let after full-depth tooth line reinforcing bar 3 and the 14 complete interlocks of voussoir groove; Tension in the direction of arrows gets final product with the urgent voussoir stator 11 of hammer kind tool then, uses this jointing; Reinforcing bar should be got curved with one heart in advance, and after reinforcing bar connected like this, two reinforcing bars could be straight with one heart.More than these reinforcing bar types of attachment, reinforcing bar will be set mould from steel mill, the groove that extrusion needs is made the sleeve of the groove that matches with it and the connection that voussoir could be accomplished reinforcing bar again.
The beneficial effect of the utility model is, make simple, price is low, any diameter reinforcing bar all can connect, and easy to connect, equipment that can be specific and instrument are practiced thrift great deal of steel, bonding strength is big, the junction of reinforcing bar is the same with portion other than connected portion intensity big.
