Set up the ring stiffener rib board on the interior anchor ring of cyclic annular skeleton, the shape of cross section after the two combines is the T font. The utility model discloses an adjusting positive and negative silk bolt length, can reaching the effect of support, make positive and negative silk bolt be in operating condition in suitable position, guarantee the size meet the standard requirement of PCCP (prestressed concrete cylinder pipe) steel bell and spigot, indeformable, positive and negative screw is loosened after accomplishing to production, take out the support ring can, convenient to use.
Description
technical field:
The utility model relates to a kind of PCCP steel bell and spigot positioning device, particularly relates to a kind of PCCP steel bell and spigot support ring.
background technique:
Prestressed concrete cylinder pipe (PrestressedConcreteCylinderPipe; write a Chinese character in simplified form PCCP) refer to and be wound around ring orientation prestress steel wire with on the high-strength concrete tube core of steel cylinder, then the cement mortar protective course of spray densification thereon and the conduit pipe made.PCCP adopts steel bell and spigot, welded together with steel cylinder, and the fluted and cushion rubber of steel bell and spigot defines the flexible joint of sliding type cushion rubber, can meet comparatively small angle tower to a certain extent, be generally less than 0.5 °, to adapt to the requirement of uneven settlement; But for larger turning point, if do not take as thrust measures such as concrete town big and heavy stones, produced by internal water pressure with caliber, steering angle, the relevant axial unbalanced force of overpressure value, pipeline can be caused to be opened at jointing.
At present, there is the yielding problem of appearance in PCCP steel bell and spigot, causes size to occur deviation, affect construction precision, and then affect quality of connection, add construction cost.
model utility content:
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, provide a kind of reasonable in design, structure is simple, easy to use and connect reliable PCCP steel bell and spigot support ring.
The technical solution of the utility model is:
A kind of PCCP steel bell and spigot support ring, containing cyclic skeleton, described cyclic skeleton is provided with a cross-section mouth, the inner ring surface of the described cyclic skeleton of described cross-section mouth both sides arranges a connecting plate respectively, one end rotary type of the silk bolt positive and negative in respectively of connecting plate described in each is connected, the other end of two described positive and negative silk bolts screws respectively with the two ends of a positive and negative silk braid cylinder and is connected, and described positive and negative silk braid cylinder is provided with clamping mechanism.
Described positive and negative silk braid cylinder is provided with four rib sides or six rib sides, and described four rib sides or six rib sides, as described clamping mechanism, are convenient to spanner and fix.Or described positive and negative silk braid cylinder is provided with through hole, and described through hole, as described clamping mechanism, is convenient to dwang and is inserted.
Described through hole is circular hole, or is strip hole; The stationary axle that described rotary type connects is pin or bolt.The inner ring surface of described cyclic skeleton is arranged cyclic reinforcing rib plate, the shape of cross section after the two combination is T-shaped.
The beneficial effects of the utility model are:
1, the utility model is by the positive and negative silk bolt length of adjustment, the effect of support can be reached, make positive and negative silk bolt in running order in place, ensure the size conforms standard-required of PCCP pipe steel bell and spigot, indeformable, unclamp positive and negative screw after production completes, take out support ring, easy to use.
2, the utility model arranges cyclic reinforcing rib plate on the inner ring surface of cyclic skeleton, improves bulk strength, and support force is stronger, more can ensure that the ovality of steel bell and spigot meets the demands, and convenient construction is installed.
3, the utility model processing is simple, connection is reliable, and can prevent heavy caliber PCCP steel bell and spigot from deforming in production welding and transportation process and causing installing, it is applied widely, is easy to promotion and implementation, has good economic benefit.
accompanying drawing illustrates:
Fig. 1 is the structural representation of PCCP steel bell and spigot support ring;
A-A sectional view in Fig. 2 Fig. 1.
Embodiment:
Embodiment: see in Fig. 1 and Fig. 2, figure, 1-cyclic skeleton, 2-cyclic reinforcing rib plate, the positive and negative silk bolt of 3-, 4-pin, 5-connecting plate, the positive and negative silk braid cylinder of 6-.
PCCP steel bell and spigot support ring contains cyclic skeleton 1, cyclic skeleton 1 is provided with a cross-section mouth, wherein: the inner ring surface of the cyclic skeleton 1 of cross-section mouth both sides is arranged respectively a connecting plate 5, one end rotary type of every a plate 5 silk bolt 3 positive and negative in is respectively connected, the other end of two positive and negative silk bolts 3 screws respectively with the two ends of a positive and negative silk braid cylinder 6 and is connected, and positive and negative silk braid cylinder 6 is provided with clamping mechanism.
Positive and negative silk braid cylinder 6 is provided with four rib sides or six rib sides, four rib sides or six rib sides, as clamping mechanism, are convenient to spanner and fix, by spanner, positive and negative silk braid cylinder 6 is rotated, thus make the quick feeding simultaneously of two positive and negative silk bolts 3 or exit, and efficiency is high.
Certainly, positive and negative silk braid cylinder 6 also can be provided with through hole, through hole is as clamping mechanism, and be convenient to dwang and insert, dwang drives positive and negative silk braid cylinder 6 to rotate.Through hole is circular hole, or is strip hole; The stationary axle that rotary type connects is pin 4 or bolt.
The inner ring surface of cyclic skeleton 1 is arranged cyclic reinforcing rib plate 2, the shape of cross section after the two combination is T-shaped, improves overall structural strength.
During use, the cyclic skeleton 1 processed by given size is positioned over the inner side that PCCP manages steel-molded joint socket, by adjusting positive and negative silk bolt length, to reach the effect of support, make positive and negative silk bolt in running order in place, ensure the size conforms standard-required of PCCP pipe steel bell and spigot, indeformable.Unclamp positive and negative screw after production completes, take out support ring.
The above, it is only preferred embodiment of the present utility model, not any pro forma restriction is done to the utility model, every above embodiment is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
