Abstract
The utility model relates to a rain-proof cover of prestressing force steel strand wires, including an outer tube, the one end mouth of pipe internal diameter of outer tube is greater than the external diameter of prestressing force steel strand wires stretch-draw ground tackle, reduce gradually from the outer tube middle part to outer tube other end cross-section, a mouth of pipe department installation apron of little cross-section end, establish an interior sleeve pipe on the apron inner wall, interior sheathed tube external diameter equals the orificial internal diameter of outer tube little cross-section end, be greater than the diameter of the circle of encircleing all steel strand wires through-holes on the ground tackle, set up corresponding steel strand wires jack according to steel strand wires through-hole quantity and the overall arrangement on the ground tackle on the apron inner wall, every steel strand wires jack is the pipe that an internal diameter equals steel strand wires diameter, pipe one end and apron inner wall fixed connection, the axis of steel strand wires jack is parallel with the axis of interior sleeve pipe and outer tube. The utility model discloses can fix the cover on steel strand wires and ground tackle, effectively protect steel strand wires and ground tackle.
Description
Technical Field
The utility model belongs to the technical field of the road bridge construction, a concrete member construction that adopts prestressing force is related to, concretely relates to rain-proof cover of prestressing force steel strand wires.
Background
The bridge concrete beam widely adopts prestressing force structure. As shown in fig. 1, a plurality of prestressed steel strands 1 in a prestressed pipeline of one hole of a concrete beam are inserted into steel strand through holes of a steel strand tensioning anchorage device 2 and are fixed by clamping pieces. During the tensioning construction and after the tensioning is finished, the ends of the steel strands and the anchorage devices are exposed outside the box girder, and the steel strands and the anchorage device clamping pieces are easily corroded due to frequent rain caused by long construction period, so that the steel strands can be failed to be tensioned seriously. This problem generally does not receive the attention at present, and at the building site, safeguard measure adopts the plastic cloth to wrap up or cover the steel strand wires usually, or establishes a sleeve pipe on the steel strand wires simply to overlap, drops easily, and the protecting effect is not good.
Disclosure of Invention
The utility model aims at the above-mentioned problem, provide a rain-proof cover of special prestressing force steel strand wires.
The technical scheme of the utility model as follows:
the utility model provides a rain-proof cover of prestressing force steel strand which characterized in that: including an outer tube, the one end mouth of pipe internal diameter of outer tube is greater than the external diameter of prestressing force steel strand wires stretch-draw ground tackle, reduces from the outer tube middle part to the outer tube other end cross-section gradually, and the mouth of pipe department of outer tube small cross-section end installs an apron, establish an interior sleeve pipe on the apron inner wall, interior sheathed tube external diameter equals the orificial internal diameter of outer tube small cross-section end, and interior sheathed tube internal diameter is greater than the diameter of the circle of surrounding all steel strand wires through-holes on the ground tackle, lies in the intraductal quantity and the overall arrangement of steel strand wires through-hole on the ground tackle on the apron inner wall and sets up corresponding steel strand wires jack, and every steel strand wires jack is the pipe that an internal diameter equals the steel strand wires diameter, pipe one end and apron inner wall fixed connection, the axis of steel strand wires jack is parallel with the axis of interior sleeve pipe and outer tube.
The utility model discloses simple structure, convenient to use can fixed cover on steel strand wires and ground tackle, effectively protects steel strand wires and ground tackle, has better practicality.

Detailed Description
As shown in fig. 2, fig. 3, fig. 4, the utility model discloses an outer tube 3, the one end mouth of pipe internal diameter of outer tube is greater than prestressing force steel strand stretching anchorage device 2's external diameter, reduces from outer tube middle part to outer tube other end cross-section gradually, and the mouth of pipe department of outer tube small cross-section end installs an apron 4, establish an interior sleeve pipe 5 on the apron inner wall, interior sheathed tube external diameter equals the orificial internal diameter of outer tube small cross-section end, and interior sheathed tube internal diameter is greater than the diameter of the circle of surrounding all steel strand through-holes on the anchorage device, and the intraductal within range of interior cover that lies in on the apron inner wall sets up corresponding steel strand jack 6 according to the quantity and the overall arrangement of the steel strand through-hole on the anchorage device, and every steel strand jack 6 is the pipe that an internal diameter equals the steel strand diameter, pipe one end and apron inner wall fixed connection, and the axis of steel strand jack is parallel with the axis of interior sleeve pipe and outer tube.
The utility model discloses during the implementation, the pipe diameter of the big diameter end of outer tube should not be too big, and its internal diameter can set up to be greater than ground tackle external diameter 5mm, can overlap on ground tackle can.
The utility model discloses during the use, take off apron 4 earlier, with the major diameter pot head of outer tube 3 on ground tackle 2, promote the outer tube forward, when treating the steel strand wires end and expose the little diameter end of outer sleeve, insert the steel strand wires jack 6 on the apron with each steel strand wires end, promote the apron forward, during interior sleeve pipe 5 on will lapping inserts the outer tube, interior sleeve pipe passes through frictional force with the outer tube and fixes, and the steel strand wires is covered in the outer tube completely.
Claims (2)
