Abstract

The utility model discloses a SMC cable tray, it includes groove box and elbow, the groove box comprises tank bottom and capping, and the tank bottom main part is the dovetail groove form, and wall upper end in both sides has horizontal turn -ups, and the capping is equipped with the top, and the top both sides are equipped with downwardly extending's vertical turn -ups, the elbow constitutes with the elbow lid at the bottom of by the elbow, is bent and is formed by aforesaid one section tank bottom at the bottom of the elbow, and the elbow lid is bent and is formed by aforesaid one section capping, and the both ends with the elbow lid at the bottom of the elbow all are equipped with the connecting seat, at the bottom of the elbow of the tank bottom of groove box and capping, elbow and the elbow lid all adopt the independent shaping of SMC material extrusion. It adopts the SMC material extrusion shaping, have better insulating nature, fire resistance and corrosion resistance, and intensity is higher, need not to maintain, and long service life, its matter is transportation and installation gently and easily, and its thermal -insulated nature is good, and coefficient of expansion is little, is difficult for the emergence deformation and breaks, its structural design is reasonable, and the location is comparatively convenient with the fastening, and the installation effectiveness is high.

Description

A kind of SMC cable tray

Technical field

The utility model relates to a kind of cable laying auxiliary facility, particularly relates to a kind of SMC of employing material and makes and have the cable tray of superperformance.

Background technology

Cable tray is the groove box placing cable in fire prevention system, in present building and factory construction, along with the surge of power consumption and the aging of part circuit, the overheated spontaneous combustion of cable phenomenon on fire happens occasionally, once cable is on fire, the words controlled are not found in the very first time, the intensity of a fire can propagate into each corner very soon along with cable, simultaneously because cable itself belongs to inflammable thing, the flame lighted of other positions is also easy to be lighted being exposed to outer cable, thus cause disaster hidden-trouble, cable tray has certain fire protecting performance, cable can be isolated in closed space, and then greatly reduce the generation of above-mentioned accident, play an important role in building cable system.There is many deficiencies in current cable tray, as: it adopts combining structure of bottom land and groove lid, and both realize locating and being connected by the fixing hole on the side plate that is affixed after fastening, and are fastenedly connected operation and comparatively bother, efficiency is lower, is not easy to erection simultaneously and installs; The metal materials such as current cable tray many employings steel or aluminium alloy are made, and to be worth and easily stolen owing to having larger recycling, and then to there is very large potential safety hazard, metal material mostly easily oxidation corrosion simultaneously, useful life is lower; Its insulation property are not good, easily electric leakage accident occur; The material thermal conductivity that it adopts is high, and the coefficient of expansion is large, easily deforming and producing larger thermal stress, affecting the cooperation of sub-assembly and easily breaking when there is the larger temperature difference; Current cable tray is mostly comparatively heavy, installs inconvenience, improves erection cost.

Utility model content

The purpose of this utility model is to provide a kind of with low cost, intensity, fire-retardant, insulation and corrosion resistance and good, long service life, processing and install SMC cable tray all comparatively easily.

For realizing above-mentioned technical purpose, the utility model adopts following technical scheme:

A kind of SMC cable tray, it comprises groove box and for carrying out the elbow combined between groove box;

Described groove box is made up of bottom land and groove lid, bottom land main body is trapezoidal channel-shaped, upper end, two side has the horizontal flange outwards extended, and described groove is covered with for covering bottom land top suitable for reading, both sides, top be provided with to downward-extension for buckling the vertical flange outside horizontal flange;

Described elbow by the bottom of elbow and elbow lid form, formed by aforesaid one section of bottom land bending at the bottom of described elbow, described elbow lid is formed by the bending of aforesaid one section of groove lid, is equipped with the Connection Block being respectively used to be socketed with the bottom land of groove box and groove lid at the bottom of described elbow with the two ends of elbow lid;

At the bottom of the elbow of the bottom land of described groove box and groove lid, elbow and elbow lid all to adopt SMC material to extrude shaping separately.

Have the arch of an arc in the middle part of described groove lid, both sides, arch are respectively equipped with the horizontal part for fitting with the horizontal flange of bottom land, and two vertical flange are separately positioned on the outside of two horizontal parts; Described horizontal part and horizontal flange are provided with the fastener hole for being fastenedly connected.

Be provided with a dividing plate in described bottom land, the middle and lower part in bottom land is divided into two parallel parts by dividing plate.

The utility model has following beneficial effect: because it adopts the extrusion modling of SMC material, is easy to processing, have good insulating properties, anti-flammability and corrosion resistance, and intensity is higher, and Maintenance free maintains, long service life; Because its cost is lower, recycle value little, the generation of stolen situation can be avoided; Its density is low, light weight and easily transport and install; Its thermal insulation is good, and the coefficient of expansion is little, not easily deforms, not easily break by during temperature difference influence; Owing to adopting arch design in the middle part of groove lid, longitudinal strength certainly will be added; In addition, because the structural design of bottom land and groove lid is comparatively reasonable, location is with for convenience fastening, and installation effectiveness is high.
