Abstract
The utility model belongs to Construction Technique of Box field, prestress wire fixing end anchorage bracing means is used for more particularly to one kind, it solves the problems, such as that prestress wire fixing end anchorage is connect with rear backing plate not generate concrete sandwich closely and cause loss of prestress there are hidden danger of quality, including the U-shaped fixing piece on the outside of fixing end anchorage is arranged in, spacing collar and billet, fixture nut is connected with after there are two U-shaped fixing piece settings and the horizontal through-hole for running through billet, fixture nut is integral by U-shaped fixing piece and billet fixation, sleeve body is provided with external screw thread and can be threadedly coupled with the threaded hole of billet until the one end of spacing collar far from tappet head is held out against with fixing end anchorage.The utility model helps to improve the construction quality of prestress wire fixing end, while also having prevented to connect as prestress wire fixing end anchorage with rear backing plate and not generated hidden danger of quality caused by concrete sandwich closely.
Description
Technical field
The utility model belongs to Construction Technique of Box field, and in particular to one kind is used for prestress wire fixing end anchorage
Bracing means.
Background technique
Largely there is fixing end p-type anchorage in box girder pre-stressed design, is worn after p-type anchor extruding steel strand wires in work progress
Enter rear backing plate, carries out steel strand tension after the completion of concreting, steel twisted-line tension-force needs to pad after passing to by p-type anchorage
Plate passes to concrete using rear backing plate to complete pre-stress construction.Usual way is to make p-type anchorage top before concreting
Next backing plate, but because steel strand wires are than comparatively dense in practice of construction, concreting process is vibrated, is impacted, and is difficult to ensure p-type anchor
Tool and rear backing plate keep close-fitting state, and in-between interlayer easy to form, concrete sandwich is prone to wear to form sky after the completion of tensioning
Gap causes loss of prestress, and there are hidden danger for construction quality.
Summary of the invention
The utility model connect to solve prestress wire fixing end anchorage with rear backing plate and does not generate concrete closely
Interlayer causes loss of prestress to there are problems that hidden danger of quality, provides a kind of for the reinforcing of prestress wire fixing end anchorage
Device.
The utility model is achieved by the following technical solution: one kind is reinforced for prestress wire fixing end anchorage
Device, including U-shaped fixing piece, spacing collar and billet on the outside of fixing end anchorage is arranged in, billet is rectangular slab, steel pad
It is provided with the threaded hole to match with fixing end anchorage anchor point quantity on plate and 4 symmetrically arranged through-holes, U-shaped fixing piece are
Structure is U-shaped and open end has externally threaded connector, and there are two U-shaped fixing piece settings and the horizontal through-hole for running through billet
After be connected with fixture nut, fixture nut is integral by U-shaped fixing piece and billet fixation, and spacing collar includes sleeve body,
The end of sleeve body is provided with tappet head, and sleeve body is provided with external screw thread and can be threadedly coupled with the threaded hole of billet
Until the one end of spacing collar far from tappet head is held out against with fixing end anchorage.
Tappet head is interior hexagonal structure and can be tightened by allen wrench.
The utility model has the beneficial effect that compared with prior art
The utility model is designed reasonably, the prestress wire using U-shaped fixing piece, spacing collar and billet composition are solid
The bracing means of fixed end is respectively to be threadedly coupled with the multiple spot of spacing collar by U-shaped fixing piece, can be by original fixing end
Anchorage and the realization of rear backing plate hold out against closely connected, efficiently solve in construction because of sky caused by intensive, concreting of steel strand wires etc.
Gap problem.The utility model helps to improve the construction quality of prestress wire fixing end, while also having prevented due to answering in advance
Power fixed end of steel wire strand anchorage is connect with rear backing plate does not generate hidden danger of quality caused by concrete sandwich closely.

Specific embodiment
The utility model is specifically addressed in referring to Fig.1~Fig. 4, and one kind adds for prestress wire fixing end anchorage
It is fixedly mounted with and sets, U-shaped fixing piece 1, spacing collar 4 and billet 3 including 5 outside of fixing end anchorage is arranged in, billet 3 is rectangle
Plate is provided with the threaded hole 7 to match with 5 anchor point quantity of fixing end anchorage and 4 symmetrically arranged through-holes 8 on billet 3,
U-shaped fixing piece 1 is that structure is U-shaped and open end has externally threaded connector, and there are two the U-shaped settings of fixing piece 1 and level is passed through
It is connected with fixture nut 2 after wearing the through-hole 8 of billet 3, fixture nut 2 is integral by U-shaped fixing piece 1 and the fixation of billet 3, limit
Position sleeve 4 includes sleeve body 9, and the end of sleeve body 9 is provided with tappet head 10, and sleeve body 9 is provided with external screw thread and energy
It is enough to be threadedly coupled with the threaded hole 7 of billet 3 until the one end of spacing collar 4 far from tappet head 10 is held out against with fixing end anchorage 5.
Carry out what prestress wire fixing end anchorage 5 was reinforced using the utility model method particularly includes:
Billet 3 is processed first, and the threaded hole 7 to match with 5 anchor point quantity of fixing end anchorage is processed on billet 3
And 4 symmetrically arranged through-holes 8；Further, the rear backing plate 6 of original fixing end anchorage 5 is transformed, on its surface
Four through holes are bored, the spacing and size of through hole are identical as through-hole 8 on billet 3；Process U-shaped fixing piece 1, it is desirable that U-shaped solid
Two open ends for determining part 1 can run through 3 through-hole 8 of rear 6 through hole of backing plate and billet；Further, in the threaded hole of billet 3
Spacing collar 4 is screwed into 7 respectively, until spacing collar 4 is held out against with fixing end anchorage 5；It will be U-shaped solid eventually by fixture nut 2
The open end for determining part 1 is locked, and fixing end anchorage 5 and rear backing plate 6 is enabled to remain close connection.
