Building electromechanical installation bridge pre-embedded sleeve

The utility model relates to the technical field of embedded sleeve equipment, and discloses a building electromechanical installation bridge frame embedded sleeve which is characterized in that positioning devices are sleeved outside the left end and the right end of an embedded pipe, a partition plate is fixedly connected to the upper surface of the embedded pipe, and an outer pipe is fixedly connected to the upper surface of the partition plate; a connecting plate is fixedly connected to the upper surface of the outer pipe, a protection device is connected into the upper surface of the connecting plate in a sleeved mode, the pre-buried pipe can be well fixed through a positioning device, and therefore the situation that the pre-buried pipe deviates due to the influence of external force, errors are generated, and construction is affected is avoided; the pre-buried pipe is fixed to a designated position through the threaded rod, so that the position accuracy is ensured, the pre-buried pipe can be well suppo
