Specific embodiment
Below in conjunction with the accompanying drawings the technical solution of the utility model is further illustrated with implementation method.It is understood that this
The described specific embodiment in place is used only for explanation the utility model, rather than to restriction of the present utility model.Further need exist for
Illustrate, for the ease of description, the part related to the utility model is illustrate only in accompanying drawing and not all.
Referring to Fig. 1 and Fig. 2, a kind of splicing rack deformed bar anchorage that the utility model embodiment is provided, including anchor
Tool body, anchorage body is used Split type structure, is spliced by bolt by upper anchor slab 1 and lower anchor slab 2, under upper anchor slab 1
At least one semi-cylindrical upper groove is provided with surface, and correspondence is provided with the semicircle of equal number on the upper surface of lower anchor slab 2
Cylindricality low groove, after upper anchor slab 1 and lower anchor slab 2 are spliced, upper groove and low groove form the main lumen therethrough 3 of accommodating reinforcing bar.
Split type structure is used by by anchorage body, design is simple, it is easy to dismount, construction rapidly and efficiently, is easy to cleaning, no
It is only applicable to splice rack, by prestress application on the reinforcing bar or truss of rack, and can applies pre- suitable for other needs
The project of stress.
Specifically, anchorage body is cuboid, a length of 80 to 86 millimeters, a width of 24 to 28 millimeters, a height of 38 to 44 millimeters.
Preferably, upper anchor slab 1 and lower anchor slab 2 is highly identical.
Exemplarily, the quantity of upper groove can be preferably 1, then the quantity of low groove mutually should be 1, upper groove and low groove
The main lumen therethrough 3 being spliced is located at the center of anchorage body.On upper anchor slab 1, or on lower anchor slab 2, positioned at main insertion
Two auxiliary lumen therethroughs 4 are symmetrically arranged with the both sides of chamber 3.
It is arranged symmetrically by by lumen therethrough, intensity and uniform force, power transmission is rationally, reliable and stable, can efficiently control steel
The displacement and deformation of muscle, with stronger anchoring property.
Specifically, a diameter of 11 to 15 millimeters of main lumen therethrough 3, a diameter of 8 to 12 millimeters of auxiliary lumen therethrough 4, two auxiliary
Lumen therethrough 4 between the end face center of circle of one end at intervals of 62 to 68 millimeters, when two auxiliary lumen therethroughs are located on upper anchor slab, then two
The distance of the upper surface of anchor slab 1 is 12 to 16 millimeters on the distance of center circle of individual auxiliary lumen therethrough 4, when two auxiliary lumen therethroughs are located on lower anchor slab
When, then the distance of anchor slab lower surface is 12 to 16 millimeters under two distance of center circle of auxiliary lumen therethrough 4.
Preferably, the diameter with diameter greater than the auxiliary lumen therethrough 4 in both sides of middle main lumen therethrough 3.The lumen therethrough of different-diameter can
