附图说明 DRAWINGS
图 1是本发明实施例构造示意图。 1 is a schematic view showing the construction of an embodiment of the present invention.
具体实施方式 detailed description
本发明的塑料合金防火电缆桥架，包括槽形支架体 1和设于槽形 支架体上方的上罩板 2， 其特征在于： （1 )所述的上罩板具有排气通 孔 3,其上部设有排气通道 5; (2)所述的槽形支架体内侧面上设有由 难燃有机材料制成有机隔热衬垫 4; (3)所述槽形支架体及其上罩板 由表面涂有防火漆的金属材料制成。 The plastic alloy fireproof cable tray of the present invention comprises a trough-shaped bracket body 1 and an upper shroud plate 2 disposed above the trough-shaped bracket body, wherein: (1) the upper shroud plate has an exhaust through hole 3, The upper part is provided with an exhaust passage 5; (2) the inner side of the grooved bracket is provided with an organic heat insulation pad 4 made of a flame retardant organic material; (3) the grooved bracket body and the upper cover plate thereof Made of a metal material coated with fire retardant paint.
为了更有利于局部热量的排出，所述的槽形支架体与上罩体之间 铺设有具有排气通孔 6的无机隔热隔板 7， 以形成内排气道 8， 和中
排气道 9。 In order to facilitate the discharge of local heat, an inorganic heat insulating partition 7 having an exhaust through hole 6 is formed between the grooved bracket body and the upper cover body to form the inner exhaust passage 8, and Exhaust passage 9.
为了更好保护电缆，所述的有机隔热衬垫内侧面上还设有无机隔 热衬垫 10。 In order to better protect the cable, an inorganic heat insulating gasket 10 is also provided on the inner side of the organic heat insulating gasket.
上述的有机隔热衬垫可由 PVC材料或含有 PVC的混合物或其他有 机材料制成。 The above organic heat insulating gasket may be made of a PVC material or a mixture containing PVC or other organic materials.
上述无机隔热隔板和无机隔热衬垫可分别由石膏板制成。 The above inorganic heat insulating separator and inorganic heat insulating gasket may be made of gypsum board, respectively.
当桥架正常工作时， 电缆的温升通过内排气道 8、 排气通孔 6、 中排气道 9、 排气通孔 3、 排气通道 5进行冷热空气交换进行冷却。 遇有火患时，靠近明火的桥架体内的温度上升并产生高压热气流，一 方面沿桥架的中排气道 9向两侧流动， 另一方面当排气量大时，通过 无机隔热隔板的排气通孔回串至内排气道 8， 又沿内排气道 8的两侧 流动， 还有一部分经上罩板的排气通孔 3向排气通道 5的两端排出。 一旦桥架被烧着， 上罩板的防火漆即形成泡沬体可自动封闭桥架体， 以阻止火焰侵入桥架体内，， 同时， 上罩板上通往排气通道的排气通 孔也处于堵塞状态。 此外， 当有机隔热衬垫温度到达 120°C；〜 200Ό 后便开始软化， 吸热并结碳， 最后成为优质的隔热材料以保护电缆。 同时会产生大量的烟气，又把该处大量热能从高温区送往低温区。设 于有机隔热衬垫内侧面上的无机隔热衬垫 10和无机隔热隔板 Ί也为 电缆防火提供了最后一道的保护屏障。 When the bridge is working normally, the temperature rise of the cable is cooled by the hot air exchange through the inner exhaust passage 8, the exhaust through hole 6, the middle exhaust passage 9, the exhaust through hole 3, and the exhaust passage 5. In the event of a fire, the temperature in the bridge near the open flame rises and generates a high-pressure hot air flow, which flows along the middle exhaust passage 9 of the bridge to the sides, and on the other hand, when the displacement is large, it is separated by inorganic insulation. The exhaust passage holes of the plates are returned to the inner exhaust passage 8 and flow along both sides of the inner exhaust passage 8, and a part thereof is discharged to both ends of the exhaust passage 5 through the exhaust through holes 3 of the upper cover plate. Once the bridge is burned, the fire lacquer on the upper hood forms a bubble body that automatically closes the bridge body to prevent the flame from intruding into the bridge body. At the same time, the venting opening to the exhaust passage on the upper hood is also blocked. status. In addition, when the temperature of the organic insulating gasket reaches 120 ° C; after ~ 200 Ό, it begins to soften, absorb heat and carbon, and finally becomes a high-quality insulation material to protect the cable. At the same time, a large amount of flue gas is generated, and a large amount of heat energy is sent from the high temperature zone to the low temperature zone. The inorganic thermal insulation gasket 10 and the inorganic thermal insulation barrier on the inside of the organic insulation gasket also provide the last protective barrier for cable fire protection.
