Description
Technical field
The invention belongs to building engineering field, more particularly, relate to a kind of combined steel twisted wire stopping means.
Background technology
Prestressed concrete is through the development of over half a century and progressively ripe along with the partial prestressing concept, and having broken through concrete can not tension and the constraint of cracking, has expanded its range of application greatly.At present, prestressed concrete has become the topmost a kind of structural meterials of domestic and abroad bridge engineering, for the bigger bridge of span, employed prestressing steel mostly is steel strand, but disadvantages such as weight is big, easy-to-rust that these class steel still have, the stretching process that adds steel strand is to carry out the external of stretch-draw crossbeam, needs to accept the pulling force from hundred tons of the one-tenth of jack, very easily stress is concentrated and accident such as burst apart, fracture, and construction workman is on every side produced great life danger.For example: China Patent No. is 02235214.7, open day is on December 25th, 2002, the patent document of disclosed prestressed large-span solid abdomen steel beam structure system, this disclosure of the Invention a kind of prestressed large-span solid abdomen steel beam structure system, the single span girder steel or the multispan continuous steel beam that comprise I-shaped or box section, and in the both sides of its steel beam web plate, be provided with two groups of symmetrical presstressed reinforcing steels along its length direction, these presstressed reinforcing steel both ends are anchored on the ground tackle that is fixed on the girder steel.Every group of presstressed reinforcing steel be a branch of more than, elongated or only bear the bigger 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 pass preformed hole on the frange plate, increases on the girder steel frange plate that it is corresponding with the presstressed reinforcing steel bending place and the web to be welded with the gusset of putting more energy into.The steel structure girder installation in position and fixing after, girder steel applied prestressing force constitute prestressed large-span solid abdomen steel beam structure system by two groups of presstressed reinforcing steels being carried out stretch-draw, can be used for the bigger steel building of beam span or bridge etc.
China Patent No. is 02235214.7, open day is on December 25th, 2002, the patent document of disclosed prestressed large-span solid abdomen steel beam structure system, this disclosure of the Invention a kind of prestressed large-span solid abdomen steel beam structure system, the single span girder steel or the multispan continuous steel beam that comprise I-shaped or box section, and in the both sides of its steel beam web plate, be provided with two groups of symmetrical presstressed reinforcing steels along its length direction, these presstressed reinforcing steel both ends are anchored on the ground tackle that is fixed on the girder steel.Every group of presstressed reinforcing steel be a branch of more than, elongated or only bear the bigger 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 pass preformed hole on the frange plate, increases on the girder steel frange plate that it is corresponding with the presstressed reinforcing steel bending place and the web to be welded with the gusset of putting more energy into.The steel structure girder installation in position and fixing after, girder steel applied prestressing force constitute prestressed large-span solid abdomen steel beam structure system by two groups of presstressed reinforcing steels being carried out stretch-draw, can be used for the bigger steel building of beam span or bridge etc.
Above-mentioned girder steel is used commonplace in the manufacture process of the big bridge of span, and it does not arrange the stopping means of steel strand in work progress, and steel strand are in the external tension of girder steel, and need the workman to operate to adjust the connecting portion of steel strand.If the stress that applies surpasses the tensile strength of steel strand, the accident that easily breaks threatens producing safely of workman.
