The concrete being integrated is built, the connecting bottom board structure includes being embedded in one piece of steel plate C of the precast beam structure bottom of every side,
The steel plate C is by connecting reinforcing bar together with the bar connecting in the side precast beam structure, every piece of steel plate C bottom weldering
It is connected between one piece of steel plate A, two pieces of steel plate A and is welded together by steel plate B overlap joints, the steel plate A, steel plate B inner side is welded
It is connected to connection reinforcing bar to be connected with the wet seam bar-mat reinforcement, the wet seam bar-mat reinforcement and the reinforcing bar of the precast beam structure connect
Connect.
Further, to improve antiseptic property, the steel plate is zincizing steel plate.
Two-sided welding is used between bonding strength, the connected steel plate of connection reinforcing bar to improve.
Equally, in order to improve bonding strength, the reinforcing bar and the reinforcing bar of the precast beam structure of the wet seam bar-mat reinforcement are adopted
Connected with overlapping mode.
In order to equally reach above-mentioned purpose, one is connected to by the way of overlap joint welding between the steel plate C and steel plate A
Rise.
The utility model is by setting connecting bottom board structure and making the reinforcing bar of connecting bottom board structure and precast beam structure and wet
Seam bar-mat reinforcement is firmly connected so that the wet seam construction after casting concrete is solidified as a whole, and its structural strength is high, and connects
Base arrangement is closely connected with beam body, and connecting bottom board structure turns into a part for wet seam construction, without removing again, reduces bottom
The process that mould is removed.The utility model is closed in work progress, influences small to railway, highway communication under bridge.
