Abstract

A light cable protective sleeve is characterized in that the ight cable protective sleeve is provided with a hollow sleeve, a plurality of holes are formed on the wall of the sleeve so as to reduce the weight of the sleeve, and external spiral lines are formed on the sleeve and connected with the sleeve as a whole body through one-time extrusion, or external spiral lines are welded on the sleeve. The light cable protective sleeve has the advantages that the plurality of hollow holes are formed on the wall of the sleeve to reduce the weight of the sleeve and improve the rigidity of the sleeve, the anti-deformation capacity and the heat insulation effect, thereby more effectively protecting cable bodies of a bridge. The light cable protective sleeve can prevent shock excitation of stay cables or suspenders of the bridge, and rain band formation. In addition, the spiral lines are solid and endurable, and can not be easily detached. The wall is thick, uniform and attractive, and the quality is high.

Description

Light-duty cable plastic protecting casing

Technical field

The utility model relates to a kind of protecting pipe that cable stayed bridge, suspension rod bridge or other open-air building are used, especially a kind of light-duty cable plastic protecting casing of being used for.

Background technology

At present state, inside and outside to be used for the protecting pipe that cable-stayed bridge cable and suspension bridge suspension rod use all be the protecting pipe of real wall basically, the weight of this protecting pipe itself is very heavy, causes the weight increase of bridge.Adopt the structure of real wall protecting pipe to 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 vortex, 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 band outer vortex 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.

Goal of the invention

The purpose of this utility model just provides a kind of in light weight, can effectively reduce the cable plastic protecting casing of bridge weight.

Solution of the present utility model is such: it has the sleeve pipe of hollow, has a plurality of holes on the cover tube wall, thereby reaches the purpose that alleviates casing wt.

Adopt technique scheme, can make:

1, smooth light-duty circular jacket pipe;

2, band outer vortex lightweight sheath pipe has outer vortex in the appearance of smooth light-duty circular jacket pipe; Outer vortex can adopt the structure of once extruding the outer vortex that is connected as a single entity with sleeve pipe; Also can adopt outer vortex is structure pipe circumference external welding (promptly producing earlier pipe, then at appearance welding helix).

The utility model has the advantages that: 1,, can alleviate the weight of tubing itself, strengthen rigidity, the raising non-deformability of sleeve pipe by on the wall of sleeve pipe, opening a plurality of hollow holes; Thereby 2, improved the cable body that effect of heat insulation can more effectively be protected bridge.3, 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.

The specific embodiment

The utility model includes sleeve pipe 1, outer vortex 2, hole 3 and takes over 4.

It has the sleeve pipe of hollow, has a plurality of holes on the cover tube wall, thereby reaches the purpose that alleviates casing wt, shown in figure (1,2).

In embodiment 2 of the present utility model shown in the figure (3,4), the inwall of sleeve pipe 1 is a shiny surface, and outer vortex 2 is once to extrude with sleeve pipe 1 to be connected as a single entity, and has the hole 3 that is made of two circular arcs and two semicircles on the tube wall of sleeve pipe 1.

In the embodiment of the present utility model 3 shown in the figure (5,6), the outer vortex that is located on the sleeve pipe 1 is once to extrude with sleeve pipe 1 to be one repeatedly, and the inwall of sleeve pipe 1 has helical groove, has the hole that is made of two sections circular arcs and two straight lines on the tube wall of sleeve pipe 1.

Can also be socketed with at least one deck different colours, different materials and sleeve pipe 1 at the inwall of described sleeve pipe 1 and once extrude close-fitting adapter 4, and at the inwall of sleeve pipe 1 with take over 4 inwall perforate respectively, as shown in Figure 8.

Fig. 7,9,10,11,12,13,14,15 and 16 is structural representations of opening the hole of different shape on the tube wall of sleeve pipe 1.Wherein Fig. 7 opens square opening on tube wall, Fig. 9 is the combination of long arc shape hole and circular port, structure shown in Figure 10 is the combination of slotted eye and trapezoidal hole, Figure 11 opens trapezoidal hole on tube wall, Figure 12 opens square opening on tube wall, Figure 13 is open semicircle shape hole on tube wall, and Figure 14 opens slotted eye on tube wall, Figure 15 opens the prismatic hole on the tube wall, Figure 16 is opened round hole on tube wall.
