A tensioning frustum 2, in which:
Tensioning frustum 2 be it is multiple, all tensioning frustums 2 are fixed on the trailing flank of baffle 1, all tensioning frustums 2
Position and spacing it is corresponding with beam-ends steel strand wires position；
The end face of tensioning frustum 2 is vertical with steel strand tension direction；
Corresponding position of first steel strand wires across hole 21, baffle 1 and the first steel strand wires across hole is offered on tensioning frustum 2
The second steel strand wires are offered across hole 11.
When prefabricated beam body 3, the end of prefabricated beam body 3 is arranged in using post tentioned prestressed concrete girder body beam-ends sealing off and covering anchorage typified form
Portion, and make baffle 1 concordant with the section of the beam body after sealing off and covering anchorage towards the side of prefabricated beam body 3, so that baffle 1 and pre-
Space (removing the occupied space of tensioning frustum 2) between beam body 3 processed precasts to come simultaneously with beam body, to ensure that sealing off and covering anchorage
The total quality of concrete；
By the setting of tensioning frustum 2, the both ends of prefabricated beam body 3 form the tensioning of the equipment of tensioning such as installation jack
Groove 31 meets the construction requirement of post stretching；
Beam-ends connects stubble there is no concrete to (on the length direction along beam) along bridge after the prefabricated beam body 3 such as T-type beam is prefabricated,
To substantially increase T beam overall appearance image；
When sealing off and covering anchorage, concreting only is carried out to the corresponding tensioning groove 31 of tensioning frustum 2, greatly reduces sealing off and covering anchorage work
Amount, improves sealing off and covering anchorage working efficiency, while only using area lesser flat-die when sealing off and covering anchorage, has saved construction cost；
Compared to existing sealing off and covering anchorage template, referring to fig. 4 and Fig. 5, assembly and disassembly are flexibly, easy to operate, and fast power-saving, construction speed are torn in spelling open
Degree (props up vertical bed die, two side forms and four pieces of end head formwork than fast 7~8 times of traditional anchor sealing when traditional anchor sealing；Using the utility model
Carrying out sealing off and covering anchorage only need to be in both ends Zhi Liyi block).Fig. 4 section line region is existing sealing off and covering anchorage range 32.Hatching in Fig. 3
Region is the sealing off and covering anchorage range of the utility model.
In addition, the width of frustum is gradually reduced along the direction of the root 24 far from frustum by the tensioning frustum 2 of setting,
So that tensioning frustum 2 is deviate from out of tensioning groove 31, conducive to precast beam after demoulding, ensure that higher construction effect
Rate.
Embodiment 2
On the basis of embodiment 1, the left and right sides of baffle 1 offer multiple fixation holes 12 parallel to each other, institute
The axis of some fixation holes 12 is vertical with the axis of tensioning frustum 2.In order to guarantee the intensity of precast beam, usually it is cast in prefabricated
The steel strand wires of cluster in beam slab are arranged along a straight line, when post-stretching process carries out, by tensioning equipments such as jack to cluster
Steel strand wires carry out tensioning, need to reserve at this time to fill the tensioning groove 31 of jack, therefore, the position of tensioning groove 31 should
With cluster, the position of steel strand wires that is arranged along a straight line it is corresponding, and tensioning groove 31 is shape when being poured by tensioning frustum 2
At, therefore tensioning frustum 2 is set in above-mentioned position, meet the construction needs of post stretching；In addition the end face 25 of tensioning frustum 2 is hung down
Straight steel strand wires, the i.e. vertical steel strand wires of tensioning groove 31, so that of the tensioning equipments such as jack being mounted in tensioning groove 31
Draw direction consistent with the tensioning direction of steel strand wires.
Penetrate fixation hole 12 by fixing pieces such as bolts, can by baffle 1 and basis, prefabricated beam body 3 web templates and
Wing plate template etc. is fixed, and is easy for installation and removal.
In addition, the position of the quantity of tensioning frustum 2 tensioning according to actual needs is flexibly set, to guarantee extensively applicable model
It encloses, as shown in figure 3, the quantity of tensioning frustum 2 is three.
In addition, the root 24 of tensioning frustum 2 and the end face 25 of tensioning frustum 2 are provided with rounding off.With further benefit
Deviate from out of tensioning groove 31 in tensioning frustum 2, guarantees again while to guarantee the concrete pouring quality at tensioning groove 31
High construction efficiency.
In addition, weight is larger, sets hollow knot for tensioning frustum 2 at this time since 2 height of tensioning frustum is big
Structure alleviates the volume and weight of the utility model to reduce the use of material, facilitates construction, further improves construction effect
Rate.
Embodiment 3
On the basis of embodiment 2, the height of tensioning frustum 2 reduces along dimension linear from the top down.The setting so that
The end face of tensioning frustum 2, the bottom of tensioning groove 31 are inclined-plane, draw frustum 2 high in use, the utility model installation is supported
Side is located above, when the utility model demoulds, the small knot between tensioning groove 31 of the contact area of the downside of tensioning frustum 2
Resultant force is smaller, and binding force of the contact area of the upside 22 of tensioning frustum 2 greatly between tensioning groove 31 is larger, and this is practical new
Type itself has certain weight, and under its own weight, the upside 22 of tensioning frustum 2 can easily separate, and under tensioning frustum 2
Side 23 is due to being set smaller than tensioning cone for the height of the downside 23 of tensioning frustum 2 by the relatively bad separation of Gravitative Loads
The height of the upside 22 of platform 2 is deviate from out of tensioning groove 31 to be conducive to tensioning frustum 2, avoids damaging tensioning when abjection
The concrete of groove 31 guarantees in turn ensure high construction efficiency while the concrete pouring quality at tensioning groove 31.
In addition, baffle 1 and tensioning frustum 2 are integrally formed.Since post tentioned prestressed concrete girder body beam-ends sealing off and covering anchorage typified form needs
Have certain intensity, thus it is common to use steel is made, when adopt be made of a steel when, in order to prepare conveniently, by baffle 1 and tensioning
Frustum 2 is prepared using integrally formed technique.
As a kind of above-mentioned integrally formed mode: baffle 1 and the casting of tensioning frustum 2 are structure as a whole.
Although above having made detailed description to the utility model with generality explanation and specific embodiment,
On the basis of the utility model, it can be made some modifications or improvements, this is apparent to those skilled in the art
's.Therefore, these modifications or improvements on the basis of without departing from the spirit of the present invention, belong to the utility model and want
Seek the range of protection.
