Device for fixing prefabricated beam bridge face water drain pipe

Abstract

The invention relates to a device for fixing a prefabricated beam bridge face water drain pipe, and belongs to a fixing device used during railroad engineering prefabricated beam construction, and particularly relates to an installing fixing device for the prefabricated beam bridge face water drain pipe. The device comprises a handle device, an upper portion fixing device and a bottom fixing device, the upper portion fixing device is characterized in that a connecting pull rod is sleeved with a protection pipe, and a spring is sleeved with the position, between a first round steel plate and a second round steel plate, in the protection pipe; and the bottom fixing device is characterized in that two crescent steel plates are arranged on a wedge-shaped steel ring upper opening, a bottom steel plate is arranged on a wedge-shaped steel ring lower opening, and a connecting hole is formed in the bottom steel plate. The device has the beneficial effects that the condition that bottom movement of the water drain pipe happens during concrete vibration or rebar movement can be effectively prevented, it is guaranteed that disturbance influences on the installing position of the water drain pipe during pouring and vibration are avoided, and the installing quality of the water drain pipe can be effectively controlled.

Description

technical field [0001] The invention belongs to a fixing device during the construction of prefabricated beams in railway engineering, in particular to a fixing device for installing and fixing drain pipes of prefabricated beam bridge decks. Background technique [0002] High-speed railway prefabricated girder bridge deck drain pipes are made of PVC pipes, which are light in weight and difficult to fix with the outer mold. The accuracy of the installation position of the drain pipes will definitely be affected during the concrete pouring and vibration process. Improper installation of the drainpipe not only makes it difficult to discharge the bridge area water, but also affects the appearance quality of the beam body. Under the influence of current construction conditions, construction technology and other factors, the installation of drain pipes has become a difficult problem in the construction of box girders. Contents of the invention [0003] The problem to be solved ...
