Abstract
The invention discloses an inhaul cable protecting bush and relates to the technical field of architectural engineering. Each half-tube body is provided with a draw-bore pin and a mortise, wherein the draw-bore pin and the mortise are arranged on two connection parts. Protruded spiral rib bars are arranged on the outer side faces of the half-tube bodies. According to the two half-tube bodies, under the status that the draw-bore pin of one half-tube body is inserted into the mortise of the other half-tube body to form a round tube, the spiral rib bars on the exteriors of the two half-tube bodies are in mutual butt joint. According to the inhaul cable protecting bush, the problem of wind-and-rain shock excitation of an ordinary high-density polyethylene protecting bush can be solved.
Description
Technical field
The present invention relates to construction engineering technical field, especially a kind of protective jacket of building guy cable.
Background technology
Building guy cable is the critical component that is applied on construction work, especially bridge structure, drag-line inside is steel wire, finalized the design by the band colligation, pack into again the high density polyethylene (HDPE) sheath, protective sleeve of pulling cable plays the antisepsis of hawser, the cross section profile of drag-line is circular, and the pe sheath surface is comparatively smooth.This ganoid pe sheath easily causes rain wind induced vibration under the service condition with wind and rain, i.e. significantly vibration, and in order to solve this rain wind induced vibration, it is in the pe sheath surface soldered, spiral convex rib to be arranged that a kind of technical scheme is arranged.But, this external surface is very inconvenient with installing and using of the protective sleeve of pulling cable of spiral convex rib, generally, for the convenience of producing and transporting, this protective sleeve of pulling cable is made the specification of 6-8 rice length mostly, and a lot of bridge cables often reach km, even longer, so long bridge cable need to be sleeved on a large amount of protective sleeve of pulling cable on long bridge cable when above-mentioned protective sleeve of pulling cable is installed one by one, also need each root protective sleeve of pulling cable is welded together in the junction, engineering quantity is quite large, and the operation difficult even can't be constructed under many circumstances.In order to solve many protective sleeve of pulling cable by the inconvenience of root suit and welding, people have invented a kind of protective sleeve of pulling cable, and the mutual fastening by the junction surface surrounds a tubular shape to this protective sleeve of pulling cable by two-part semicanal.One in two junction surfaces of this semicanal is draw pin, and another is tongue-and-groove.But the protective sleeve of pulling cable lateral surface that this semicanal fastens remains smooth, does not have the effect that prevents rain wind induced vibration.
Summary of the invention
Technical problem to be solved by this invention is to provide the protective sleeve of pulling cable of the anti-exciting of a kind of efficient corrosion resisting, and this protective sleeve of pulling cable can solve the problem of general high density polyethylene (HDPE) sheath rain wind induced vibration.
In order to address the above problem, the technical solution used in the present invention is: this protective sleeve of pulling cable, have half body that is provided with respectively draw pin and tongue-and-groove at two junction surfaces, and be provided with the spiral rib of projection at the lateral surface of described half body.
In above-mentioned protective sleeve of pulling cable technical scheme, technical scheme can also be more specifically: the draw pin of described two and half bodys by their sides inserts in the opposing party's tongue-and-groove and consists of under the state of pipe, and the external spiral rib of these two semicanals docks mutually.
Owing to having adopted technique scheme, the present invention compared with prior art has following beneficial effect:
The helix of the protrusion of protective sleeve of pulling cable external surface can stop the formation of rain line, has the effect of weather proof exciting.
The installation of sheath is simple and convenient, and jacket inner wall can not be subject to the damage of drag-line steel wire.
Description of drawings
Fig. 1 is the structural representation of protective sleeve of pulling cable.
Fig. 2 is Fig. 1 top view.
Fig. 3 is the structural representation of half body.
Fig. 4 is the top view of Fig. 3.
Fig. 5 is the I place enlarged drawing of Fig. 2.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing embodiment:
Include half body that is provided with respectively draw pin 2 and tongue-and-groove 3 at two junction surfaces as Fig. 1 to protective sleeve of pulling cable shown in Figure 5, be provided with the spiral rib 1 of projection at the lateral surface of half body.During installation, with two and half bodys with between drag-line parcel and they, their sides' draw pin 2 is inserted the opposing party's the interior formation pipe of tongue-and-groove 3, drag-line is surrounded in this pipe, consist of under the state of pipe, the external spiral rib 1 of these two semicanals mutually docks and forms continuous helix, until the part that need to protect at drag-line all fills upper body half.This protective sleeve of pulling cable, stop the formation of rain line, effectively prevent the rain wind induced vibration of drag-line and install simple and conveniently, can carry out sheath and install after drag-line installs, do not hinder the inwall of protective sleeve of pulling cable, change circular pipe type sheath in the past and be installed to unfavorable situation on drag-line before must be fixing at drag-line two ends.The present invention both can be used for the installation construction of new bridge, can be used for again maintenance and the replacing of old bridge protective sleeve of pulling cable.Effect with weather proof exciting has greatly improved the antiseptic property of drag-line.
Claims (2)
1. a protective sleeve of pulling cable, have half body that is provided with respectively draw pin (2) and tongue-and-groove (3) at two junction surfaces, it is characterized in that: the spiral rib (1) that is provided with projection at the lateral surface of described half body.
2. protective sleeve of pulling cable according to claim 1, it is characterized in that: the draw pin (2) of described two and half bodys by their sides inserts in the opposing party's tongue-and-groove (3) and consists of under the state of pipe, spiral rib (1) docking mutually that these two semicanals are external.
