Planar four-communication bridge pipeline joint

The invention discloses a planar four-communication bridge pipeline joint. The planar four-communication bridge pipeline joint comprises a communication device bottom plate which is provided with communication device extending ends along four directions; each of the communication device extending ends is in the shape of a rectangular groove; the upper end of the communication device extending end is provided with an inward right-angle folded edge; heat radiation holes are formed at two end side surfaces of the communication device extending end; the inward right-angle folded edge of the communication device extending end is least 1.8cm; the heat radiation holes are long round holes which are longitudinally arranged; and glass fiber reinforced plastic plates with the thickness of 0.3cm to 0.8cm are adopted as longitudinal baffle plate. According to the planar four-communication bridge pipeline joint of the invention, the glass fiber reinforced plastic plates are adopted as the longitudinal baffle plates, and the thickness of the glass fiber reinforced plastic plates ranges from 0.3cm to 0.8cm, and therefore, the weight of the whole device is reduced, and a bearing effect can be realized to the greatest extent.
