Abstract
The utility model provides a plastic cable protecting bushing. The utility model is characterized in that the outer wall of the bushing is provided with an outer screw thread, the outer screw thread and the busing are extrusion molded into a whole, the inner wall of the bushing can be smooth, and a plurality of through hollow holes along the longitudinal direction of the bushing can be drilled on the wall of the bushing. The utility model can prevent the wind and rain agitation of the stay-cable and the suspender of the bridge, and can prevent the rain line from coming into being, the helix line is fast and durable, and cannot break off easily. The thickness of the wall is even and artistic with good quality; by arranging a plurality of hollow holes on the wall of the bushing, the weight of the tube body can be lessened, the rigidity of the bushing is enhanced, and the distortion resistance is improved.
Description
Technical field
The utility model relates to a kind of plastic protecting casing that cable stayed bridge, suspension rod bridge or other open-air building are used that is used for.
Background technology
At present state, inside and outside be used for the protecting pipe that cable-stayed bridge cable and suspension bridge suspension rod use and have two kinds: a kind of is smooth real wall circular jacket pipe, and this protecting pipe in use suspension cable or suspension rod can produce rain wind induced vibration, and Heavy Weight, and bridge weight is increased.Another kind is the real wall protecting pipe that has outer helical, though this protecting pipe has solved the problem of the formation of suspension cable or suspension rod rain line and rain wind induced vibration, the weight of protecting pipe itself is still very heavy.And the real wall protecting pipe of the outer helical of band also has following defective: 1, the real wall protecting pipe of domestic existing band outer vortex is in the obvious attenuation of local wall thickness that plays outer vortex, inhomogeneous; 2, the outer vortex of external existing outer vortex protecting pipe is in the external welding of pipe circumference, promptly produce pipe earlier, at the external surface welding helix of pipe, the helix of the outer vortex protecting pipe of Sheng Chaning is insecure in this way, very easily comes off in engineering is used again.
Summary of the invention
The purpose of this utility model just provides and a kind ofly can solve existing protecting pipe and playing the wall thickness attenuation of outer vortex place, and rigidity, the non-deformability of pillar are low; The welded type helix comes off easily, and suspension cable or suspension rod can produce rain wind induced vibration in use, the rain line forms and the cable plastic protecting casing of the problem of itself insufficient rigidity, Heavy Weight.
Solution of the present utility model is such: the outer wall at sleeve pipe is provided with outer vortex, and described outer vortex and sleeve pipe are that an extrusion molding is connected as a single entity, and the inwall of described sleeve pipe can be a shiny surface; The protecting pipe of this structure can be avoided because of playing wall thickness attenuation that outer vortex causes, inhomogeneous or problem that outer vortex comes off easily.
In above-mentioned scheme: on the wall of described sleeve pipe, can have the hollow hole of a plurality of perforations of vertically opening along sleeve pipe, in order to alleviate the weight of protecting pipe.
The utility model has the advantages that: 1, outer vortex and the tube wall owing to sleeve pipe is connected as a single entity for once extruding, therefore both can prevent that rain wind induced vibration, the rain line of bridge stay cable or suspension rod from forming and its helix firm and durable by outer vortex, difficult drop-off, wall thickness is even, attractive in appearance, and quality is good; 2, by on the wall of sleeve pipe, opening a plurality of hollow holes, can alleviate the weight of tubing itself, strengthen rigidity, the raising non-deformability of sleeve pipe; Thereby 3, improved the cable body that effect of heat insulation can more effectively be protected bridge.

The specific embodiment
The utility model includes sleeve pipe 1, outer vortex 2, hole 3, takes over 4.
Outer wall at sleeve pipe 1 is provided with outer vortex 2, and this outer vortex 2 is that an extrusion molding is connected as a single entity with sleeve pipe 1.
In embodiment of the present utility model shown in attached Fig. 1 and 2, the inwall of sleeve pipe 1 is a shiny surface, and wall thickness is even, and the intensity high conformity has outer vortex 2 on its outer wall.
In embodiment of the present utility model shown in accompanying drawing 3,4 and 16, can also be socketed with one deck or two-layer different colours, different materials and sleeve pipe 1 are once extruded close-fitting adapter 4 at the inwall of described sleeve pipe 1, can also on the wall of sleeve pipe 1 and adapter 4, distinguish perforate, as shown in Figure 6.
At Fig. 5,7,8,9,10,11,12,13, among the embodiment of the present utility model shown in 14 and 15, on the wall of sleeve pipe 1, have the hollow hole 3 of a plurality of vertical perforations of opening along sleeve pipe, these hollow holes 3 can be long arc shape holes as schematically shown in Figure 5, slot as shown in Figure 7, or circular port as shown in Figure 8 and the combination of long arc shape hole, or the combination of slotted eye as shown in Figure 9 and trapezoidal hole, or as the trapezoidal hole of Figure 10, the square opening of Figure 11 and the semi-circular hole of Figure 12, the slotted eye of Figure 13, the prismatic hole of Figure 14 and the circular port of Figure 15.
The hole 3 of opening on the tube wall of sleeve pipe also can be a threaded hole, the direction of the outer vortex on the hand of spiral of this threaded hole and the sleeve outer wall can be identical also can be opposite, as shown in figure 17.The cross sectional shape of the outer vortex of once extruding with sleeve pipe on sleeve outer wall 3 can be a kind of in square, rectangle, triangle, trapezoidal, semicircle, half elliptic etc., also can be several combinations, and helix quantity can be 1 to 500.When producing, can be chosen in as required and open difformity, perforation on the tube wall or do not connect straight hole or threaded hole.
When being combined with in the sleeve pipe 1 when taking over 4, sleeve pipe 1 and the material of adapter 4 can be that commaterial, identical color are made, and also can add different colours to show difference; Sleeve pipe 1 can be made with different materials with adapter 4, also can add different colors and distinguish.
