The utility model content
The utility model has overcome the deficiency of prior art; Improved type prestressed concrete steel strand anchor fitting is provided; Solve when putting steel strand in the prior art; The whole winding group can move with the dilatory end of steel strand, can not draw many steel strand simultaneously, puts the defective that many steel strand make steel strand be intertwined easily simultaneously.
For solving above-mentioned technical matters; The utility model adopts following technical scheme: a kind of improved type prestressed concrete steel strand anchor fitting, comprise by upper connecting rod group, lower connecting rod group, head rod group and the second pipe link group and intersect the support of forming, with upper connecting rod group cross-perpendicular in conplane upper limit bar group; Upper connecting rod group and upper limit bar group form a upper cavity; With lower connecting rod group cross-perpendicular in conplane lower limit bar group, lower connecting rod group and lower limit bar group form a lower chamber, and an adapter plate is arranged in the perpendicular between upper cavity and lower chamber; And on the adapter plate on the lower connecting rod group, be provided with spacing hole; Upper limit bar group is parallel to lower limit bar group, and said upper connecting rod group is parallel to the lower connecting rod group, and the head rod group is parallel to the second pipe link group; The head rod group and the second pipe link group are simultaneously perpendicular to the head rod group and the second pipe link group; Said lower connecting rod group centre portion is the spiral embossing shape, and length is at least the width that adapter plate has spacing bore portion, and said spacing hole is three and rectangular distribution.
On the lower connecting rod group of described adapter plate rear positioning plate is arranged.
Be distributed with the corresponding through hole with spacing hole on the described positioning plate, through hole and spacing hole are on same straight line.
Described adapter plate is perpendicular to upper connecting rod group or lower connecting rod group.
Described adapter plate is fixed in cooresponding upper cavity and the lower chamber at two ends up and down.
Described positioning plate is parallel to adapter plate.
Compared with prior art, the beneficial effect of the utility model is:
(1) the utility model upper connecting rod group and lower connecting rod group are provided with adapter plate; Can realize stretching to steel strand; And the whole winding group is moved with the dilatory end of steel strand; Be provided with and the cooresponding positioning plate of adapter plate in the adapter plate rear end, with fixing before and after the steel strand, drawing effect is better.
(2) the adapter plate lower end of the utility model is provided with three spacing holes; Can stretch to many steel strand simultaneously; Be provided with positioning plate in the rear end, positioning plate be provided with spacing hole on same straight line and cooresponding through hole, make many steel strand stretch simultaneously and also can not be intertwined.
(3) the utility model is set to the spiral embossing shape at the centre portion of lower connecting rod group; Increase the friction force of pipe link group and steel strand; When the cylindrical steel twisted wire lies in when passing spacing hole on the lower connecting rod group and stretch, can on the lower connecting rod group, not slide arbitrarily.
Description of drawings
Fig. 1 is the utility model structural representation.
The figure acceptance of the bid is kept the score and is not expressed as: 1, upper limit bar group; 2, upper connecting rod group; 3, lower limit bar group, 4, the lower connecting rod group; 5, head rod group; 6, the second pipe link group; 7, adapter plate; 8, spacing hole; 9, positioning plate.
The specific embodiment
Do further to set forth below in conjunction with 1 pair of the utility model of accompanying drawing, but the embodiment of the utility model is not limited thereto.
The utility model comprises the support of being made up of upper connecting rod group 2, lower connecting rod group 4, head rod group 5 and the second pipe link group, 6 intersections; With upper connecting rod group 2 cross-perpendicular in conplane upper limit bar group 1; Upper connecting rod group 2 forms a upper cavity with upper limit bar group 1; With lower connecting rod group 4 cross-perpendicular in conplane lower limit bar group 3, lower connecting rod group 4 forms a lower chamber with lower limit bar group 3, and an adapter plate 7 is arranged in the perpendicular between upper cavity and lower chamber; And on the adapter plate on the lower connecting rod group 47, be provided with spacing hole 8; Upper limit bar group 1 is parallel to lower limit bar group 3, and said upper connecting rod group 2 is parallel to lower connecting rod group 4, and head rod group 5 is parallel to the second pipe link group 6; The head rod group 5 and the second pipe link group 6 are simultaneously perpendicular to the head rod group 5 and the second pipe link group 6; Said lower connecting rod group 4 centre portions are the spiral embossing shape, and length is at least the width that adapter plate 7 has spacing hole's 8 parts, and said spacing hole 8 is three and rectangular distribution.On the adapter plate 7 rear lower connecting rod groups 4 positioning plate 9 is arranged, adapter plate 7 is perpendicular to upper connecting rod group 2 or lower connecting rod group 4, and adapter plate is fixed in cooresponding upper cavity and the lower chamber at two ends about in the of 7.Be distributed with the 8 corresponding through holes with spacing hole on the positioning plate 9, through hole and spacing hole 8 are on same straight line, and positioning plate 9 is parallel to adapter plate 7.
