Abstract
The invention discloses a raindrop-shaped stainless steel wire distribution pipe for a stay cable steering device of a cable-stayed bridge tower. The cross section of the raindrop-shaped stainless steel wire distribution pipe is gradually changed from the semi-round shape for the upper part to the raindrop shape for the lower part, the straight-line section of the lower part is tangent to the circular arc of the upper part, the straight-line section and a symmetric axis form an angle of 30 degrees, a fillet is formed at the lower end, and the inside radius of the fillet is 3.5 mm. As the straight-line section and the symmetric axis of the raindrop-shaped stainless steel wire distribution pipe form the angle of 30 degrees, the radial force of a cable strand acts on the pipe wall, the pipe wall generates certain opposite force and applies the certain opposite force to the cable strand, and the cable strand is clamped. Therefore, an inner pipe is not required to be filled with epoxy mortar for closing and anchoring, stranded steel wires are guaranteed to be parallel and not interfere with each other, full compatibility with mounting of a single strand of stay cable and a tension system is achieved, the requirement on tension space is also lowered at the same time, and conveniences are brought to cable replacement in future.
Description
Technical field
The present invention relates to a kind of raindrop shape stainless steel for Cable-stayed Bridge Pylon cable inhauling steering gear and divide fiber tube.
Background technology
The structure of saddle that domestic and international Cable-stayed Bridge Pylon adopts is many to be made up of inner and outer pipe, and wherein, pipe uses the more of circular point fiber tube, and Cheng Qiaohou pours into epoxy mortar and carries out closed anchoring in interior pipe.The saddle of this structural form, because epoxy mortar is by steel strand and interior pipe conglutinate, therefore on the one hand there is the situation of extruding mutually in suspension cable, singlely can not carry out adjustment stretch-draw, can only entire beam tension; And resistant slide performance is not good; Also certain difficulty is brought to changing rope from now on the other hand.
Summary of the invention
The object of the present invention is to provide one can produce chucking power to strand, to the installation of drag-line sub-thread and tensioning system, there is the fully compatible raindrop shape stainless steel for Cable-stayed Bridge Pylon cable inhauling steering gear with being convenient to change rope and divide fiber tube.
Its technical scheme is: a kind of raindrop shape stainless steel for Cable-stayed Bridge Pylon cable inhauling steering gear divides fiber tube, comprise raindrop shape stainless steel and divide fiber tube, raindrop shape sub-wire tube section is that top is semicircle to bottom raindrop shape gradual change, bottom straightway and top circular arc tangent, straightway becomes 30 degree of angles with the axis of symmetry, lower end rounding, and fillet inside radius is 3.5mm, it is characterized in that: described raindrop shape stainless steel divides fiber tube to begin from saddle outlet position, to stretch out an extension by intrinsic radius.
Its Advantageous Effects is: because raindrop shape stainless steel divides the straightway of fiber tube to become 30 degree of angles with the axis of symmetry, therefore make the radial load of strand act on tube wall, tube wall produces again certain counter-force to strand, and the rubbing action of strand and tube wall, thus form the clamping to strand, thus both carried out closed anchoring without the need to inwardly managing interior perfusion epoxy mortar at Cheng Qiaohou, in turn ensure that steel hinge line is parallel and do not interfere with each other, to the installation of drag-line sub-thread and tensioning system, there is sufficient compatibility, effectively eliminate and use multiply stretch-draw jack difficulty greatly to the restriction of drag-line specification, also reduce the requirement to stretch-draw space simultaneously, return and change rope from now on and bring conveniently, its structure is simple, and processing and fabricating is easy, and material cost is lower.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present invention;
Fig. 2 is the A-A sectional drawing of Fig. 1;
Fig. 3 is the B-B sectional drawing of Fig. 1.
Sequence number in above-mentioned figure: raindrop shape stainless steel divides fiber tube 1, non-bending steel cable 2, saddle outlet position 3, extension 4, osculum 5.
Detailed description of the invention
As shown in Figure 2 and Figure 3, a kind of raindrop shape stainless steel for Cable-stayed Bridge Pylon cable inhauling steering gear divides fiber tube, high 37mm, wide 28mm is pressed into by the stainless pipe of external diameter 32mm, wall thickness 1.5mm, circular position internal diameter 12.5mm, wall thickness 1.5mm, bottom straightway and top circular arc tangent, straightway becomes 30 degree of angles with the axis of symmetry, lower end rounding, fillet inside radius is that the raindrop shape stainless steel of 3.5mm divides fiber tube 1.
The chucking power of fiber tube to drag-line is divided to cause the fatigue failure of suspension cable in order to reduce raindrop shape stainless steel, raindrop shape stainless steel divides fiber tube to begin from saddle outlet position 3, to stretch out an extension 4 by intrinsic radius, make steel strand can divide the centre outlet spout of fiber tube at raindrop shape stainless steel.
The impact of outlet spout on steel strand of fiber tube is divided for reducing raindrop shape stainless steel further, a wide 5mm is respectively opened in the upper and lower parts of above-mentioned extension 4, the osculum 5 of long 100mm, to reduce the damage that raindrop shape stainless steel divides the friction of the fiber tube mouth of pipe to cause to non-bending steel cable 2.
Claims (2)
1. one kind is divided fiber tube for the raindrop shape stainless steel of Cable-stayed Bridge Pylon cable inhauling steering gear, comprise raindrop shape stainless steel and divide fiber tube, raindrop shape sub-wire tube section is that top is semicircle to bottom raindrop shape gradual change, bottom straightway and top circular arc tangent, straightway becomes 30 degree of angles with the axis of symmetry, lower end rounding, fillet inside radius is 3.5mm, it is characterized in that: described raindrop shape stainless steel divides fiber tube (1) to begin from saddle outlet position (3), to stretch out an extension (4) by intrinsic radius.
2. a kind of raindrop shape stainless steel for Cable-stayed Bridge Pylon cable inhauling steering gear according to claim 1 divides fiber tube, it is characterized in that: a wide 5mm is respectively opened in the upper and lower parts of described extension (4), the osculum (5) of long 100mm.
