Abstract
The utility model relates to a protective groove for communication cables, comprising a groove body and a groove cover which are made of fiber reinforced composite material. The groove cover with turnover edges and a concave groove body are tightly buckled together and form a hollow cylinder which can be used as a protective body for communication cables. The protective groove has the advantages of light weight, high intensity, good insulating property and fireproof property, aging resistance, long service life, and low cost and is very convenient to assemble, construct, maintain, and transport.
Description
The utility model is relevant with the communication cable protector.
Along with developing rapidly of communication career, the use amount of communication cable increases rapidly, from aluminium cable, copper cable in the past, to the fibre optics cable in the present age, guarantee all must protect cable spacious leading to of telecommunication.China all was to use a kind of cement prefab when various cable is installed in the past, and every about 0.5-1 rice is long, coupled together protective as cable.This protective cost is low, but volume is big, and is very heavy, and the breakage rate height is not easy to construction and maintenance.
Development in recent years the protective of a kind of plastic tube as cable, light weight has overcome cement product heaviness, bulky defective.But when cable laying, still need to construct with segmentation cross-under mode, cumbersome, and also this plastic tube weatherability is poor, intensity is low, and the cost height is not prevented fires, particularly also be subjected to termite attack easily in south, this poling mounting means still is not easy to installation, maintenance.
The purpose of this utility model is to provide a kind of light weight, and the intensity height is ageing-resistant, and fire line is good, cracky not, and installation, maintenance is the cable protection body easily.
The utility model provides the protective of a kind of open type cable protective trough as communication cable, and it is made up of a cell body and groove lid.Said cell body is Integratively formed with fibre reinforced composites, the concavity cell body of open at both ends.The groove that is mated lid also is with the fibre reinforced composites one-shot forming, and the link closely edge of cell body of two downward flange is arranged on the both sides of groove lid, closely cooperates with cell body and forms a hollow column.
The groove lid of this cable protective trough can be designed to various ways, and a kind of preferred design is to be semicircle dome-shaped shell structure in the utility model.This structure is born geostatic pressure and is considered it all is more rational from groove lid and cell body.The both sides of groove lid and the junction at cell body edge also have a road sealing groove, can certainly not establish this road sealing groove, but this structural design, can be more closely knit when groove lid and cell body are closed, simultaneously also play a kind of good supporting role, improved the rigidity of whole protection body.Match with the groove lid, make some corresponding constructions in cell body edge suitable for reading and change, making it is very natural thing in conjunction with more closely knit that.
More than She Ji this cable protective trough can be connected in turn with plug-in type or dock during use, and the version of each interface also is pre-designed.When cable laying is constructed, the protection cell body is put into geosyncline, in protective trough, lay various cables simultaneously, cover the groove lid thereafter and get final product.
It has been seen in that from above statement this cable protective trough that uses the utility model to provide can open wide laying when cable laying construction, in a cable protective trough, can lay many cables simultaneously, it is more convenient to construct.And be convenient to maintenance overhaul, and can repeat repeatedly to carry out installation, than the cable protective tube side of tubular structure just many, can improve efficiency of construction 5-10 doubly.
This cable protective trough product that the utility model provides, thickness are in the 8-10 millimeter, and actual test data shows that its bending strength is 1765 * 10
4Pa, hot strength is 24516.6 * 10
4Pa, impact strength is 2157.5 * 10
4Pa has very high intensity.And its very light weight, about about 15 kilograms, its weight of the utility model product of same capability has only 1/5th to 1/8th of cement products greatly for every meter weight.This goods insulating properties, fire line are good, corrosion-resistant, ageing-resistant, particularly can prevent the infringement of termite, and reach more than 30 years its useful life.
Relend below and help accompanying drawing, the utility model is described in further detail with an example
Fig. 1 is a phantom view of the present utility model;
Fig. 2 is the A-A view of groove lid among Fig. 1;
Fig. 3 is the sectional structure chart of Fig. 1.
The communication cable protective trough that the utility model proposes is to use a kind of fibre reinforced composites, the open type cable protective trough of making as materials such as the inorganic material of macromolecule resin class, magnesite breeze and so on or plastic, rubber classes.As shown in Figure 1, comprise a cell body 1 and groove lid 2.There are two downward flange 3 on both sides at the groove lid, and the both sides of groove lid and the junction at cell body edge also are respectively equipped with a road sealing groove 4.Form a hollow column after groove lid and the cell body closure, connect these hollow columns and promptly constitute communication cable protective trough described in the utility model.
The utility model has the advantages that clearly, the cable protective trough made from this fibre reinforced composites, its weight only has 1/8th of cement product, its intensity height, good insulation preformance, corrosion-resistant, ageing-resistant, fire line is good, and cost is low, long service life, and installation, maintenance, transportation are all very convenient, can guarantee the safe operation of communication cable.
Claims (3)
1, a kind of communication cable protective trough, it is characterized in that forming by a cell body and groove lid, said cell body is Integratively formed with fibre reinforced composites, the concavity cell body of open at both ends, the groove that is mated lid also is with the fibre reinforced composites one-shot forming, is closely cooperated and is formed a hollow column by the link closely edge of cell body and cell body of two downward flange on the both sides of groove lid.
2, according to the described cable protective trough of claim 1, it is characterized in that said groove lid is semicircle dome-shaped shell structure, the both sides of groove lid and the junction at cell body edge are provided with seal groove.
