Abstract
The utility model relates to an adjustable prestressing tensioning limiter, which is characterized in that a limiter body is composed of a limiting block and a casing, wherein a through hole used for penetrating a steel strand is arranged in the limiting block which is movably connected with the casing. The length of an outer hole of the casing is changed by adjusting the arranged position of the limiting block in the casing, so an optimum limiting dimension which is required during the anchoring process is obtained. Simultaneously, the junction point of the limiting block and the casing is provided with a locking positioning mechanism. The utility model not only can adjust the limiting dimension at the construction site at any moment in a stepless mode to meet requirements for tensioning and anchoring steel strands matched with anchoring systems in various types and specifications, but also can be used continuously after the limiter is adjusted on site in time when the limiter is ground to change the tensioning dimension after the limiter is used for a period of time. The utility model has the advantages of flexible, convenient and quick operation, long service life and high repeating utilization factor, and can ensure that the limiting dimension is stable and reliable to accelerate the construction progress and ensure the safe production when the adjustable prestressing tensioning limiter is used.
Description
Technical field
The utility model relates to the prestressed stretch-draw stop that uses in a kind of building trade, the adjustable stop of particularly a kind of prestressed stretch-draw.
Background technology
Usually, the prestress anchoraging system is in the stretch-draw anchor work progress, be to adopt limiting plate to carry out anchoring mostly, its structure of this limiting plate is an overall structure, and, it is provided with the through hole that is used for steel strand, one end of this through hole is provided with and is used for straight hole spacing and that have the spacing length of definite value, though this limiting plate is simple in structure, with low cost, but because the required spacing size of same model ground tackle that each manufacturer produced is not quite similar, and the actual franchise of steel streakline is bigger, the diameter of steel strand will produce bigger influence to the spacing size of ground tackle, so make in the practical application, every batch of ground tackle and the steel strand supporting with it all need carry out test of many times and can determine optimum size before tension ground tackle, avoid because of improper loss that causes of spacing selection of dimension and accident, and because the spacing certain value that is of a size of of this limiting plate, can't adjust, have only during use the lathe of utilization repeatedly the spacing size of redjustment and modification can adopt, it is not only comparatively bothered, and, the repeat usage of the limiting plate after the redjustment and modification is also lower, particularly tensioned anchorage system mainly is to be applied to highway at present, in the middle of the bridge construction, the job site all is positioned at ungetable remote location, limit by the building site condition and be difficult to finish redjustment and modification according to determined optimum size scene to limiting plate, both wasted time and energy and seek cooperation unit's processing modification, incured loss through delay the construction period again, simultaneously, construction quality also is difficult to guarantee.
The utility model content
The utility model is the deficiency that exists in the above-mentioned background technology, providing a kind of can adjust its spacing size at convenient, fast scene, makes it to reach best spacing length, and, simple in structure, long service life can be guaranteed the adjustable stop of prestressed stretch-draw of construction quality.
Its concrete solution is: the stop body is made of limited block and overcoat two parts, and limited block is provided with the through hole that is used for steel strand, and this number of openings can be provided with as required, and limited block and overcoat adopt movable connection method.Can in overcoat, the length that the position changes the overcoat endoporus being set by adjusting limited block, required best spacing size when obtaining anchoring.
In addition then, described limited block and the movable connection method of overcoat employing are for being threaded.
Moreover limited block and overcoat junction are provided with locking positioning mechanism.
The utility model is owing to adopt the stop body that is made of limited block that is movably connected and overcoat, and can both be locked by locking positioning mechanism, make it carry out stepless adjustment to spacing size at any time at the construction field (site), satisfy the stretch-draw anchor requirement of the supporting steel strand of anchor system of various models, specification, and, produce wearing and tearing when this stop uses a period of time, when spacing size changes, after the scene is in time adjusted, still can continue to use.The utility model flexible and convenient operation, quick, long service life, recycling rate of waterused height.Can guarantee in the use that spacing dimensionally stable is reliable, quicken programming, guarantee safety in production.
Description of drawings
Fig. 1 is the structural front view of embodiment 1.
Fig. 2 is the structural front view of embodiment 2.
Fig. 3 is the structure side view of embodiment 2.
The specific embodiment
Embodiment 1
This practicality example is the adjustable stop of single hole prestressed stretch-draw.
Among Fig. 1, limited block 3 is provided with a through hole that is used for steel strand vertically, and the limited block 3 that is positioned at overcoat 1 and overcoat 1 constitute the stop body for being threaded.And locking positioning mechanism 2 employings of locking limited block 3 and overcoat 1 both relative positions is a lock-screw.
When adjusting spacing size, rotational lock screw at first, open locking positioning mechanism, then the rotary spacing piece 3, realize the stepless adjustment of spacing size L by moving forward and backward the position of limited block in overcoat 1, when spacing size L reaches requirement, rotatable locking screw, the relative position of locking overcoat 1 and limited block 3, it is constant to guarantee that spacing size L stablizes in application process.
Embodiment 2
Present embodiment is the adjustable stop of porous prestressed stretch-draw.
Among Fig. 2, Fig. 3, the limited block 3 that constitutes the stop body and overcoat 1 are still for being threaded.But be provided with 4 through holes 6 that are used for steel strand on the limited block 3 vertically, and locking positioning mechanism be by lock-screw 4 and be arranged on lock-screw and limited block between pad 5 constitute.
Claims (3)
1, the adjustable stop of a kind of prestressed stretch-draw, it is characterized in that the stop body is made of limited block (3) and overcoat (1) two parts, and this limited block is provided with in the through hole with steel strand, and limited block (3) adopts movable connection method with overcoat (1).
2, the adjustable stop of prestressed stretch-draw according to claim 1, the movable connection method that it is characterized in that the employing of limited block (3) and overcoat (1) is for being threaded.
3, the adjustable stop of prestressed stretch-draw according to claim 1 is characterized in that limited block and overcoat junction are provided with locking positioning mechanism (2).
