Abstract

The utility model discloses an adjustable elastic limiting plate for an anchor cable. According to the adjustable elastic limiting plate, a high-strength spring is arranged in a cylindrical piece; a circular baffle is arranged on the high-strength spring; the diameter of the circular baffle is matched with the inner diameter of the cylindrical piece; when the high-strength spring is compressed, the circular baffle can be embedded in the cylindrical piece; corresponding perforations are formed at the bottom of the cylindrical piece and on the baffle; and the number of the perforations is consistent with that of steel strands of the anchor cable, and each steel strand of the anchor cable penetrates through the high-strength spring and a pair of corresponding perforations. According to the adjustable elastic limiting plate, a fixed groove depth structure of the original limiting plate is changed into an adjustable groove depth structure controlled by the high-strength spring, the cylindrical bottom of the limiting plate is always attached to an anchorage device, and the inside baffle is always matched with the exposed quantity of a clamping piece under the control of the high-strength spring, and therefore, the clamping piece is always subjected to thrust of by the spring.

Description

The adjustable elastic limiting plate that anchor cable is used
Technical field
The utility model relates to the anchor cable that the geotechnical engineering anchoring is used.
Background technology
Present stage, along with the day by day maturation of Anchorage Technology, China's engineering construction is annual uses a large amount of prestress anchorage cable, anchor pole, because the superiority of prestress anchorage cable, make it in engineering support, account for very important status, and whether prestress application successfully become the most important thing.Owing to being to adopt limiting plate location, ground tackle locking behind the prestress application, so the fit structure of locking degree and ground tackle and limiting plate has much relations.
The limiting plate of existing ground tackle adopts the deep trouth fixed form, in use find following drawback: because groove depth, the tolerance that steel strand, ground tackle, intermediate plate etc. are made, cause the amount of exposing of groove depth and intermediate plate not mated, when groove depth is excessive, larger space is arranged between limiting plate and the intermediate plate, cause limiting plate to lose effect should be arranged, can't limit the position of intermediate plate, in the time of lifting jack unloading, can occur moving after certain at the effect lower clamping piece of huge stress like this, thereby cause stress loss in various degree, cause the stretch-draw poor effect; When groove depth is crossed when shallow, directly contact with limiting plate because intermediate plate is long, cause the load of jack can't be applied on the ground tackle and all be applied on the intermediate plate, intermediate plate can produce huge frictional resistance under the huge bond stress effect of ground tackle and between the steel strand like this, thereby cause intermediate plate locking phenomenon to occur, frictional resistance between intermediate plate and the steel strand even can offset most thrust, thereby can't all be delivered to jack load on the steel strand or cause intermediate plate fracture of wire to occur, stripped thread phenomenon and the serious adverse consequences of steel strand scratch, these situations all can reduce the service behaviour of steel strand even stay potential safety hazard.
The utility model content
In order to overcome the deficiencies in the prior art, the utility model improves existing limiting plate, develops a kind of novel adjustable elastic elastic spacing plate, and the different adjustment groove depth of the intermediate plate amount of exposing guaranteed the anchorage cable stretching quality when it can be according to anchorage cable stretching.
The adjustable elastic limiting plate that a kind of anchor cable is used, it is characterized in that, it is to lay the high strong spring of the major diameter that is complementary with the cylindrical element internal diameter in a cylindrical element, lay circular baffle plate above the high strong spring, circular baffle plate diameter and cylindrical element internal diameter are complementary, and circular baffle plate can embed in the cylindrical element when high-strength spring-compressed; Cylindrical element bottom is provided with corresponding perforation with baffle plate, and the perforation number is consistent with the radical of anchor cable steel strand, and the per share steel strand of assurance anchor cable pass from the high strong spring of major diameter and corresponding two perforation.
The adjustable elastic limiting plate that a kind of anchor cable is used, it is characterized in that, it is to lay the high strong spring of a plurality of minor diameters that equates with anchor cable steel strand radical in a cylindrical element, lay circular baffle plate above the high strong spring, circular baffle plate diameter and cylindrical element internal diameter are complementary, and circular baffle plate can embed in the cylindrical element when high-strength spring-compressed; The cylindrical element bottom is provided with corresponding perforation with baffle plate, the perforation number is consistent with the radical of anchor cable steel strand, and the high strong spring of minor diameter is corresponding between cylindrical element bottom perforated and baffle perforations one by one, and the per share steel strand that guarantee anchor cable pass from the high strong spring of minor diameter and corresponding two perforation.
Operating principle of the present utility model and good effect are:
(1) the holddown groove deep structure with original limiting plate changes into by high-strength spring controlled adjustable slit deep structure, ground tackle is close at the cylinder end of limiting plate all the time, the baffle plate of the inside adapts to the amount of exposing of intermediate plate all the time under the control of high strong spring, thereby guarantees that intermediate plate is subject to the thrust of spring all the time;
(2) in the process that Qian Jin Ding Give anchor cable loads, load is added on the ground tackle all the time, and along with the elastic elongation of steel strand, ground tackle and limiting plate are when moving forward gradually like this, intermediate plate also can move forward under the effect of high strong spring gradually, thereby guarantees that intermediate plate is positioned at the anchor hole bottom all the time;
(3) when lifting jack unloading, intermediate plate can in time pin under the effect of ground tackle bond stress, avoids occurring excessive loss of prestress, thereby guarantees the service behaviour of anchor cable; Thereby effectively improve the anchor cable construction quality.
(4) this limiting plate is simple in structure, and profile is small and exquisite, and constituent part is few, avoids the too much trouble of part, makes things convenient for the workman to construct.
