Description
Technical field
The invention belongs to building engineering field, more particularly, relate to a kind of plug pin type steel strand stopping means.
Background technology
Prestressed concrete is through the development of over half a century and progressively ripe along with prestressing technique, and having breached concrete can not the constraint of tension and cracking, greatly extends its range of application.At present, prestressed concrete has become the topmost a kind of structural meterials of domestic and abroad bridge engineering, for the bridge that span is larger, the prestressing steel used mostly is steel strand, but the disadvantages such as weight is large, easy-to-rust that this kind of steel still have, add that the stretching process of steel strand carries out the external of stretch-draw crossbeam, the pulling force of the large ton amount from hydraulic tests such as jack need be accepted, very easily stress the reason such as to concentrate and burst apart, the accident such as fracture, and the steel wire of bounce-back can produce great life danger to the construction worker of surrounding.Steel wire of some bounce-back rebound people on the face or with it, the lighter can cause skin trauma, and severe one then may threat to life.But existing equipment only take into account how could better stretching steel strand when designing, seldom consider the problem of bounce-back after steel strand fracture.Such as: China Patent No. is 201220019698.8, publication date is on October 3rd, 2012, disclose the patent document that a name is called two dimension prestressing anti-fatigue girder, this invention is made up of girder steel, prestress wire, arc cushion block, Flat gasket, prestressed high-strength bolt, nut, crimping anchor head, bearing stiffener and bearing.Be with two steel strand be arranged symmetrically with, longitudinal prestressing is applied to girder steel at the web place of the nearly bottom flange of girder steel, and in beam length range, be symmetrical in web both sides, with suitable spacing high-strength bolt, transverse prestress is applied to girder steel.Under this two dimension prestressing effect, girder steel bottom flange does not enter tension stress state under Fatigue Load, under the shearing action that web produces in wheel load, sloping section main stress bar does not also enter tension state, thus guarantees that steel beam flange and web all can not produce fatigue failure.Thus make the girder steel controlled by fatigue capacity to effectively utilize high-strength steel, economize on resources, improve safety, stop fatigue failure.
China Patent No. is 02235214.7, publication date is on December 25th, 2002, disclose the patent document that a name is called prestressed large-span solid abdomen steel beam structure system, a kind of prestressed large-span solid abdomen steel beam structure system of this disclosure of the invention, comprise single span girder steel or the multispan continuous steel beam of I-shaped or box section, and being provided with two groups of symmetrical presstressed reinforcing steels in the both sides of its steel beam web plate, along its length, these presstressed reinforcing steel both ends are anchored on the ground tackle that is fixed on girder steel.Often organize presstressed reinforcing steel be a branch of more than, elongated or only bear the larger position of tensile stress at girder steel and arrange along girder steel, it can be parallel with steel beam web plate or be an angle with steel beam web plate.Presstressed reinforcing steel is bent and through the preformed hole on frange plate, its steel beam flange plate corresponding with presstressed reinforcing steel bending place and web increases and is welded with gusset of putting more energy into.Steel structure girder installation in position also, after fixing, forming prestressed large-span solid abdomen steel beam structure system by carrying out stretch-draw to two groups of presstressed reinforcing steels to girder steel Shi Hanzhang, can be used for the larger steel building of beam span or bridge etc.
Above-mentioned girder steel is applied very extensive in the manufacture process of the larger bridge of span; steel strand are in the external tension of girder steel; it is in work progress; need operative to adjust the connecting portion of steel strand; so once steel strand are pulled off and rebound; the protective device then not preventing steel strand from rebounding because fractureing because of prior art, the steel strand collapsed can threaten to the life security of workman.
