Description
Technical Field
The utility model relates to a steel fiber concrete bridge construction technical field, specifically say that the steel ingot mills shaped steel fiber concrete connection structure for the girder steel.
Background
The existing steel beams are directly connected by adopting wet joints in a mode of arranging reinforcing steel bars, so that the connection is unstable and the construction process requirement is high.
Therefore, it is necessary to design a steel ingot milling type steel fiber concrete connection structure for steel beams, which simplifies the steel beam connection construction process, reduces the construction requirements and improves the connection stability and strength on the premise of maintaining the connection firmness.
Disclosure of Invention
The utility model discloses broken through prior art's a difficult problem, designed the steel ingot for the girder steel and milled shaped steel fiber concrete connection structure to reach the simplified process, promote joint strength's purpose.
In order to achieve the purpose, the utility model discloses a steel ingot mills shaped steel fiber concrete connection structure for the girder steel, its characterized in that: and the two ends of the steel beam are provided with fixed connecting plates which are connected with the porous steel plate.
Furthermore, the porous steel plate is a steel plate provided with a plurality of through holes.
Preferably, the through holes are arranged in a matrix.
In the matrix arrangement, through hole rows with odd arrangement numbers and through hole rows with even arrangement numbers are arranged in a staggered mode.
Preferably, the through holes are arranged in a circular radial shape.
In the circular radial arrangement, the number of the through holes increases progressively from the center of the circle along the radius direction.
Compared with the prior art, the utility model, add porous steel plate at the both ends of girder steel, pass porous steel plate with the reinforcing bar, later pour the steel ingot again and mill shaped steel fiber concrete for the connection between girder steel, concrete, the reinforcing bar is more firm, has promoted bonding strength, makes the durability of girder steel junction obtain promoting, and the security performance of whole bridge promotes.

The meaning of the above terms in the present invention can be determined according to specific situations by persons skilled in the art, and should not be construed as limiting the present invention.
Referring to the figure 1, the utility model provides a steel ingot mills shaped steel fiber concrete connection structure for the girder steel sets up fixed connection board 2 in 1 both ends of girder steel, fixed connection board 2 is connected with porous steel plate 3, wherein porous steel plate 3 is for seting up the steel sheet of a plurality of through-holes 4, in concrete connection, utilizes the reinforcing bar to pass the through-hole, links together girder steel interconnect, later the pouring steel ingot mills shaped steel fiber concrete.
Preferably, the through holes 4 may be arranged in a matrix or in a circular radial pattern.
When the matrix arrangement is adopted, the through hole rows with odd arrangement numbers and the through hole rows with even arrangement numbers are arranged in a staggered manner, for example, the through holes in the 1 st row and the through holes in the 2 nd row are staggered, the through holes in the 2 nd row and the through holes in the 3 rd row are staggered, and so on.
When the circular radial arrangement is adopted, the number of the through holes 4 starting from the center of the circle along the radius direction is increased gradually, for example, 1 through hole is arranged at the center of the circle, the number of the through holes starting from the center of the circle along the radius direction is gradually increased, and the increased number can be set according to specific requirements.
In concrete implementation, at first set up at the both ends of girder steel the utility model discloses, later use the reinforcing bar to pass the through-hole, couple together the girder steel, then the pouring steel ingot mills shaped steel fiber concrete for the girder steel is connected as an organic wholely.
