Abstract
The utility model discloses a wet joint construction protection plate of an over-crossing bridge. The wet joint construction protection plate comprises a left steel plate, a middle steel plate and a right steel plate. Bolts are embedded in a left box girder flange plate and a right box girder flange plate to fix the left steel plate and the right steel plate to box girders. A transverse box girder embedded bar is connected between the left box girder and the right box girder and is welded to a longitudinal left anchoring steel bar and a longitudinal right anchoring steel bar. The left anchoring steel bar and the right anchoring steel bar are fixedly welded to the left steel plate and the right steel plate respectively. The end of the left steel plate and the end of the right steel plate are fixedly welded to the two sides of the middle steel plate respectively. According to a protection system, a train can run normally without the requirement for occupying a station track, the protection effect is good, the on-site construction environment is completely isolated from the train running environment, and it is guaranteed that construction sundries cannot drop and damage trains passing through. Meanwhile, cost is greatly reduced, a large number of contact network cables do not need to be modified, and the construction time is shortened.
Description
Technical field
The utility model relates generally to the construction of overpass beam, relates in particular to the wet seam construction of highway case beam of crossing over running railway line.
Background technology
Newly-built five lakes main road overcrossing railway overpass bridge crosses existing Huainan uplink and Huainan downlink with simple supported box beam form, become 88 ° of angles with circuit, infall Huainan Railway downlink mileage K73+343, is positioned at two Dun Ji to sieve collection interval, circuit is electric railway, headroom 9.35m.Adopt 30m simple supported box beam structure across the design of Huainan line, case deck-molding 1.6m, width is respectively 2.4m and 2.85m; Bridge deck width is 24m(single width), case beam all adopts prefabricated erection construction, and for such, across iron project, the seam that wets after box beam erection construction faces bed die fixing problem cannot be installed.
For the electrified Business Line work items of such leap, safety requirements is high, difficulty of construction is large, how after box beam erection in the attached work progress of bridge floor, ensure the safety of construction, guarantee again the unimpeded and safety of railway, do not take the space of railway, and the foreign material of can guaranteeing to construct can not fall dealing train is damaged, this has become the common important topic of paying close attention to of unit in charge of construction and unit of operation.
For above problem, in prior art, adopt set up protecting canopy frame constructure scheme more, but in this scheme implementation, needs to spend a large amount of manpower and materials, increases by 300,000 yuan of construction costs.
Utility model content
The utility model object is can not fall dealing train and contact net lines are damaged in order to ensure construction foreign material, and a kind of shoulder guard is provided.
The utility model is achieved through the following technical solutions:
A kind of wet seam construction protection plate of overpass beam, include left side steel plate, middle steel plate, right side steel plate, on the box beam flange plate of left and right side, be embedded with respectively bolt left side steel plate, right side steel plate are fixed on to case beam, between the case beam in left side and the case beam on right side, be connected with horizontal case beam embedded bar, case beam embedded bar is welded with longitudinal left anchor bar, right anchor bar, left anchor bar, right anchor bar are fixed welding with left side steel plate, right side steel plate respectively, and weld with middle steel plate both sides are fixing respectively left side steel plate, steel plate end, right side.
Between described left side steel plate, middle steel plate, right side steel plate, have the gap of wide 1cm, gap adopts 2mm steel plate to cover, and with gap, ointment shutoff both sides.
Described left side steel plate, right side steel plate thickness are 8mm, middle steel plate thickness is 2mm, material is Q345, bolt is M25 bolt, anchor bar is φ 16 reinforcing bars, described left side steel plate, middle steel plate, right side steel plate, bolt, anchor bar adopt multi-component alloy co-cementation or zincizing+reach the processing of cola+confining bed, and wherein zincizing thickness is >=50um, and confining bed thickness is 5-8um.
The utility model has the advantages that:
Adopt and shoulder guard is installed without taking station track, train is normally moved, and protection effect better on-the-spot construction environment and train operation environment isolate completely, the foreign material of can guaranteeing to construct can not fall dealing train is damaged.Reduce construction cost.
