Abstract

The utility model discloses a bury special construction tool of ground tackle deeply relates to prestressed anchorage utensil technical field, has the barrel, and its one end outer wall of this barrel is equipped with the shaft shoulder, and its other end is connected with the limiting plate through the connecting piece, and this limiting plate middle part is equipped with steel strand wires and penetrates the hole, compared with the prior art, be connected this instrument and jack, through the biography power component of barrel as the stretch -draw end, the barrel is in between ground tackle and the jack, it carries out the stretch -draw construction outward to extend to the concrete with the jack, having solved the ground tackle, to bury the concrete degree of depth big, the contained angle is little, construction difficult problems such as working space is not enough are reserved to the jack, ensure when burying anchor end stretch -draw deeply, need not to destroy concrete self structure, can accomplish the stretch -draw operation in convenient and fast ground simultaneously, the high efficiency and the security of the construction of large -scale prestressed structure improve by a wide margin, and self simple structure, convenient operation, the advantage that the commonality is strong, but the wide application is in the middle of the various prestress construction that bury anchor technology deeply.

Description

The special construction tool of buried ground tackle
Technical field
The utility model relates to prestressed anchor technical field, especially a kind of special construction tool of ground tackle of buried concrete component.
Background technology
Along with constantly carrying out of China's infrastructure, except common prestressed structure, large-scale prestressed structure is also emerged in large numbers one after another, and prestressed Construction Technology is constantly updated.When carrying out the densely distributed post-stressed concrete structure design of stretch-draw large-tonnage, prestressing tendon, adopt buried anchor technique more and more, the ground tackle tradition stretching construction technology of current use is when processing buried anchor, jack tension position is reserved in most employing, reserved area is large, again by reinforcement welding reposition after stretch-draw is complete, so not only, also there is adverse effect to structure stress in complex operation difficulty.In addition, along with the increase of ground tackle hole count, the increase of tension tonnage, the volume of corresponding jack is also huge accordingly, and needs reserved stretch-draw space also to become large, and perforated area is comparatively large, also there is difficulty to follow-up sealing off and covering anchorage.When anchored end buried depth is more shallow, jack and structural concrete surface angle larger time, employing work anchor slab, limiting plate etc., padded and lead to the method that concrete surface installs jack tension again and also substantially can carry out stretching construction, but it is darker for anchored end buried depth in works, then need by multiple work anchor slab padded when simultaneously jack is less with the surperficial angle of structural concrete, difficulty is installed, efficiency of construction is low, the most important thing is when adding work anchor slab when the mill resistance increasing steel strand in cushion block stretching process, when ground tackle is put, actual stress under anchorage reduces, certain security risk is existed to structure.
Utility model content
The utility model provides a kind of buried ground tackle special construction tool, and it can solve the existing ground tackle construction difficult problem that the Transducers Embedded in Concrete degree of depth is large when buried, angle is little, working space deficiency reserved by jack.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: have cylindrical shell, and its one end outer wall of this cylindrical shell is provided with the shaft shoulder, and its other end is connected with limiting plate by connector, is provided with steel strand and penetrates hole in the middle part of this limiting plate.
In technique scheme, technical scheme can also be more specifically: the described shaft shoulder is provided with the connecting hole be connected with jack; The connector of described limiting plate and described cylindrical shell is screw.
Owing to have employed technique scheme, the utility model compared with prior art has following beneficial effect:
1, because this construction tool has cylindrical shell, its one end outer wall of this cylindrical shell is provided with the shaft shoulder, its other end is connected with limiting plate by connector, during use, the end screw this construction tool with the shaft shoulder is arranged on the special centre-hole jack of prestressing force and makes it to be integrated, by the Force transmission parts of cylindrical shell as stretching end, cylindrical shell is between ground tackle and jack, jack is extended to outside concrete and carry out stretching construction, solve the ground tackle Transducers Embedded in Concrete degree of depth large, angle is little, jack is reserved working space deficiency and is waited construction difficult problem, guarantee when carrying out buried anchored end stretch-draw, without the need to destroying concrete self structure, stretch-draw operation can be completed quickly and easily simultaneously, significantly improve high efficiency and the safety of large-sized prestress structure construction, and self structure is simple, the advantage of easy to operate, highly versatile, in the middle of the pre-stress construction that can be widely used in various buried anchor technique.
2, because limiting plate and sleeve are connected by screw, dismantled and assembled, the ground tackle appearance and size of current each producer is basically identical, but also there are some difference in the arrangement of position, ground tackle hole, therefore the limiting plate only need changing different manufacturers when stretch-draw just can use with the ground tackle of different manufacturers, and material saved by the processing sleeve that need not repeat, reduce cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the connection diagram of the utility model and jack.
Fig. 3 is the process schematic representation that the utility model is used in the installation work anchor of the buried anchor of prestressing force.
Fig. 4 is that the utility model is used in the installation jack of the buried anchor of prestressing force and the process schematic representation of moveable anchor.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail:
As shown in Figure 1, the utility model has cylindrical shell 1, and its one end outer wall of this cylindrical shell is provided with the shaft shoulder 4, and the shaft shoulder 4 is provided with the connecting hole 6 be connected with jack 5; Its other end is connected with limiting plate 2 by screw 3, is provided with steel strand and penetrates hole 7 in the middle part of this limiting plate; As shown in Figure 2, jack 5 is connected with cylindrical shell 1 hexagon socket head cap screw 8, is integrated with jack; As shown in Figure 3, during installation work ground tackle, first by be embedded in concrete structure prestress wire 9 one by one through work anchor slab 10, then work anchor slab 10 pushed to hold out against along sleeve preformed hole be close in anchor plate 11; As shown in Figure 4, the construction method of the buried ground tackle of the utility model is as follows:
The end screw first this construction tool with the shaft shoulder is arranged on the special centre-hole jack of prestressing force and makes it to be integrated, steel strand 3 penetrate from the position, limiting plate 2 hole of jack 5 front end, again jack 5 is pushed along reserving hole channel, the work anchor slab 10 of installation in position before holding out against, and do temporary fixed; Jack 5 end erecting tools anchor 12, jack 5 and moveable anchor 12 installation in position good after, suitable afterburning pretension, make closely connected between ground tackle, sleeve preformed hole, jack and moveable anchor holding out against, ensure that each parts are along axis power transmission, remove interim constraint afterwards, carry out stretch-draw by designing requirement and job specfication.After stretch-draw terminates, successively removal tool anchor, jack, finally undertaken cutting by job specfication, the operation such as slip casting envelope paving.
