Abstract
The utility model relates to an anti-blocking grouting device for a cast-in-place continuous beam vertical prestressing rib metal corrugated pipe. The anti-blocking grouting device comprises a prestressing rib, wherein the prestressing rib penetrates in the corrugated pipe inside concrete to be cast; bolts are arranged at both ends of the prestressing rib; the lower end of the prestressing rib penetrates through an anchoring end base plate and is fixed through a nut, and the upper end of the prestressing rib penetrates through a tensioning end base plate and is fixed through a nut; a grouting hole and an exhaust hole are respectively formed in the tensioning end base plate. As the tensioning end base plate and the anchoring end base plate are arranged, the grouting hole and the exhaust hole are formed in the tensioning end base plate, one hole is used for grouting, the other hole is used for exhausting, and the functions of the two holes can be exchanged. Moreover, the cement grout pouring can be performed without auxiliary grouting by a grout presser, cement grout falls down naturally without external force, the cement grout can fall down from a plurality of holes simultaneously at a time cyclically, and the cyclic cement grout pouring can be completed within six minutes around.
Description
Technical field
The utility model relates to bridge continuous beam vertical prestressing bar construction field, particularly the anti-blocking grouting device of a kind of cast-in-situ continuous beam vertical prestressing bar metal bellows.
Background technology
In the road and bridge engineering technical field of construction, after tension of prestressed tendon is complete, need toward the interior injected water mud of bellows.The useful pneumatic mortar machine press water of traditional grouting process mud, metal bellows are in conjunction with modes such as vacuum injections, the shortcoming that these modes exist is complex process, and generally in bottom, injected hole is set, middle part arranges a plurality of steam vents, it is very high that injected hole stops up incidence, make the workload of doing over again increase, and do over again and need destroy the beam body of continuous beam, can directly have influence on quality and the safety of bridge.
Chinese patent 02156281.4 discloses the two-way slip casting construction method of a kind of vertical tube vacuum preloading and sealing filling system thereof, has namely adopted the mode of vacuum injection, and construction is comparatively complicated.
Summary of the invention
Technical problem to be solved in the utility model is to provide the anti-blocking grouting device of a kind of cast-in-situ continuous beam vertical prestressing bar metal bellows, can realize common pressure grouting, construct more for convenience, easy construction, significantly save equipment, personnel's input, improved work efficiency.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: the anti-blocking grouting device of a kind of cast-in-situ continuous beam vertical prestressing bar metal bellows, comprise presstressed reinforcing steel, described presstressed reinforcing steel penetrates and is positioned at the bellows for the treatment of pouring concrete, two ends at presstressed reinforcing steel are provided with bolt, the anchored end backing plate is passed in the lower end of presstressed reinforcing steel, and by nut, fixes;
The upper end of presstressed reinforcing steel is passed the stretching end backing plate and by nut, is fixed, and is respectively equipped with injected hole and steam vent on the stretching end backing plate.
Form sealing between described anchored end backing plate and bellows.
Described bolt and presstressed reinforcing steel are welded to connect.
The anti-blocking grouting device of a kind of cast-in-situ continuous beam vertical prestressing bar metal bellows that the utility model provides, by stretching end backing plate and the anchored end backing plate that arranges, and injected hole and steam vent be set on the stretching end backing plate, a hole is in order to slip casting, an other hole is in order to exhaust, and the function in two holes can be exchanged.And grout pouring does not need pneumatic mortar machine to assist slip casting, takes artificial to get final product, and cement paste naturally drops and need not by external force, a plurality of holes of cycling simultaneously once, and about 6 minutes, the time just can be completed the grout pouring of a circulation.The utility model has been avoided the obstruction of injected hole, has exempted because injected hole stops up and has caused the phenomenon of doing over again, and has saved the input of mud jacking equipment.The utility model is particularly useful for the construction technology of perfusion of the cement paste of cast-in-situ continuous beam vertical prestressing bar metal bellows.The utlity model has and reduce costs, accelerating construction progress, the remarkable results such as shortening construction period, raising work efficiency, workmanship is also effectively guaranteed.

The upper end of presstressed reinforcing steel 1 is passed stretching end backing plate 3 and by nut, is fixed, and is respectively equipped with injected hole 6 and steam vent 7 on stretching end backing plate 3.
Form sealing between described anchored end backing plate 4 and bellows 2.
Described bolt 5 is welded to connect with presstressed reinforcing steel 1.The material of described presstressed reinforcing steel is indented bars.The material of described bellows is iron sheet.The material of described stretching end backing plate and anchored end backing plate is steel plate.
Comprise the following steps during use:
At first put into bellows 2 before continuous beam concreting;
Presstressed reinforcing steel 1 passes bellows 2;
Presstressed reinforcing steel 1 and bellows 2 are connected and fixed by bolt 5 with stretching end backing plate 3 and anchored end backing plate 4, and anchored end bolt 5 welds with presstressed reinforcing steel 1;
, in two holes of corresponding brill, stretching end backing plate 3 both sides, be respectively injected hole 6 and steam vent 7.
By the past 2 li grout injections of bellows of injected hole 6;
Realize the construction of vertical prestressing bar metal bellows anti-clogging grouting device by above-mentioned steps.
The utility model is in practice through repeatedly applying and checking, and properties all meets the design standard requirement, and have and reduce costs, accelerating construction progress, the remarkable results such as shortening construction period, raising work efficiency, workmanship is also effectively guaranteed.
