Abstract
The utility model discloses a blocking ring for fireproof blocking material in an electric cable pipe. The blocking ring for the fireproof blocking material is fastened between an electric cable body and a cable protection pipe; the blocking ring for the fireproof blocking material comprises two semi-annular blocking rings which are symmetrically arranged; the two semi-annular blocking rings are fastened through bolts; a plurality of strengthening ribs are uniformly arranged inside the semi-annular blocking rings; a gap between the blocking ring for fireproof blocking material and the cable protection pipe mouth is filled with the fireproof blocking material. According to the sizes of the electric cable body and the cable protection pipe, the corresponding blocking ring for the fireproof blocking material in the electric cable pipe is made; the blocking ring for the fireproof blocking material in the electric cable pipe blocks the filled fireproof blocking material in the electric cable pipe, so that the sink, collapse and unevenness of the filled fireproof blocking material are prevented; the uniform, tight and aesthetically pleasing shape of the filled fireproof blocking material are ensured.
Description
Technical field
The utility model relates to one and stops circle, relates in particular to a kind of cable tube fireproof blocking and stops circle.
Background technology
At present, power engineering cable tube fireproof blocking construction, way is first to add baffle plate in the shutoff of the cable mouth of pipe conventionally, uses fire prevention calking shutoff afterwards.The effect of baffle plate is to prevent in fire prevention calking drop tubes, and the baffle plate of on-the-spot processing is generally random certain position that is stuck in the cable mouth of pipe, and after operation or placement certain hour, baffle plate may be subjected to displacement, and causes that fire prevention calking sinks, subsides.
Utility model content
The deficiency existing for solving prior art, the utility model discloses a kind of cable tube fireproof blocking and stops circle, this stop circle have simple and practical, easy to operate, reduce the advantage such as cost.
For achieving the above object, concrete scheme of the present utility model is as follows:
Cable tube fireproof blocking stops circle; fireproof blocking stops that circle is fastened between cable body and cable protection pipe; comprise that two semi-circulars that are arranged symmetrically with stop circle; two semi-circulars stop that circle passes through bolted; semi-circular stops and in circle, is evenly provided with multiple reinforcements, and fireproof blocking stops between circle and the cable protection mouth of pipe fills fire prevention calking.
Described semi-circular stops that the edge of the interior ring of circle widens thickening, and semi-circular stops the interior through matching of the size of circle and the external diameter of cable body and cable protection pipe.
Described semi-circular stops that the material of circle is fireproof silicone rubber or fire prevention sheet plate.
Described fireproof blocking stops that circle is 80 millimeters to 150 millimeters apart from the distance of the cable protection mouth of pipe.
The cable protection mouth of pipe to two semi-circular stops that the space of circle is exactly to fill the position of fire prevention calking, by the fireproof blocking of bolted stop circle can prevent for a long time fire prevention calking sinking, subside, out-of-flatness.
The beneficial effects of the utility model:
1, adopt cable tube fireproof blocking to stop that circle can improve shutoff efficiency.
2, according to the size of cable body and cable protection pipe, make corresponding cable tube fireproof blocking and stop circle, the filling fire prevention calking of shutoff cable is blocked; prevent from filling that fire prevention calking sinks, subsides, out-of-flatness; the shape that ensures packing material fire prevention calking is straight, closely knit, attractive in appearance.
Brief description of the drawings
Fig. 1 the utility model scheme of installation;
Fig. 2 the utility model cross-sectional view;
Fig. 3 the utility model planar structure schematic diagram;
In figure, 1, cable protection pipe, 2, cable body, 3, fire prevention calking, 4, cable tube fireproof blocking stops circle, 5, bolt hole, 6, reinforcement, 7, semi-circular stops circle.
Embodiment:
Below in conjunction with accompanying drawing, the utility model is elaborated:
As shown in Figure 1, cable tube fireproof blocking stops circle 4, and cable tube fireproof blocking stops that circle 4 is fastened between cable body 2 and cable protection pipe 1.
As Figure 2-3; cable tube fireproof blocking stops that circle 4 comprises that two semi-circulars that are arranged symmetrically with stop circle 7; two semi-circulars stop that circle 7 passes through bolted; semi-circular stops that circle 7 is interior and is evenly provided with multiple reinforcements 6, and cable tube fireproof blocking stops between circle 4 and the cable protection mouth of pipe 1 fills fire prevention calking 3.Semi-circular stops that the edge of circle 7 interior ring widens thickening, and semi-circular stops the interior through matching of the size of circle 7 and the external diameter of cable body 2 and cable protection pipe 1.Semi-circular stops that the material of circle 7 is fireproof silicone rubber or fire prevention sheet plate.
Cable tube fireproof blocking stops circle 4 correct installation sites: two symmetrical semi-circulars stop that bolted that circle 7 passes through two ends are in the outside of cable body 2, and the inside of cable protection pipe 1, apart from the position of 1 mouthful approximately 80 millimeters to 150 millimeters of cable protection pipes.
Two semi-circulars stop that circle 7 is provided with bolt hole 5, by bolted in cable body 2 outsides, fastening cable tube fireproof blocking after good stop circle 4 above fill fire prevention calking.
General semi-circular stops that the outer of circle 7 may be greater than the internal diameter of cable protection pipe 1, use tool processes that semi-circular is stopped to the outer of circle 7 puts into cable protection pipe 1 just;
Cable tube fireproof blocking is stopped to circle 4 is fastened on cable body 2 with bolt, 1 mouthful of cable protection pipe position inwards, to the interior filling fire prevention calking 3 of cable protection pipe 1, ensures that the shape of packing material fire prevention calking 3 is straight, closely knit, attractive in appearance by 1 mouthful of cable protection pipe.
