Abstract
The utility model provides a blocking device for a railing panel seam at a rail transit viaduct beam seam, which comprises a blocking steel plate, wherein the blocking steel plate comprises a first plate and a second plate which form a structure with an L-shaped cross section; the blocking steel plate is tightly attached to the inner side of the breast board, and the first plate is fixed on the side surface of the breast board upright post; the second plate of the containment plate is secured to the side wall of the fence. The fence seam sealing device has the advantages that the structure is simple, and the fence seam sealing effect can be effectively realized; and this block device installs after the bridge floor system construction finishes, construction convenience, durability are good, be convenient for change, with low costs, do not influence the bridge view.
Description
Technical Field
The utility model belongs to the technical field of bridge auxiliary structure construction, and particularly relates to a blocking device for fence plate seams at beam seams of a rail transit viaduct.
Background
The urban rail transit viaduct is usually laid along green belts in urban roads, prefabricated breast boards are mostly adopted on the viaduct, and 5cm wide gaps are required to be arranged at breast boards at beam gaps for longitudinal extension of beam bodies. However, during actual construction, due to processing errors and construction installation errors of the breast boards, the width of partial breast board seams is larger than 5cm and even exceeds 10 cm; the larger fence plate gap can cause foreign matters on the bridge deck to fall into the motor vehicle lane under the bridge through the fence plate gap, and the traffic safety is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the problems in the prior engineering and provides a blocking device for the rail traffic viaduct beam seam, which blocks the rail traffic viaduct beam seam by installing steel plates with the thickness of 2mm on the inner sides of the rails at two ends of the beam seam, wherein one end of each steel plate is fixedly connected with the side surface of a rail upright post through an M8 nail type anchor bolt, and the other end of each steel plate is a movable end.
The technical scheme of the utility model is as follows:
the blocking device for the railing panel seam at the rail transit viaduct beam seam comprises a blocking steel plate, wherein the blocking steel plate comprises a first plate and a second plate which form a structure with an L-shaped cross section;
the blocking steel plate is tightly attached to the inner side of the breast board, and the first plate is fixed on the side surface of the breast board upright post;
the second plate of the blocking steel plate is fixed on the side wall of the railing plate.
The first board of the blocking steel plate is fixed on the side face of the breast board stand column through a plurality of first nail type anchor bolts, and a gasket is arranged between each first nail type anchor bolt and the blocking steel plate.
The second plate of the blocking steel plate is provided with a plurality of movable end bolt holes, and second nail type anchor bolts are implanted into the movable end bolt holes to fix the second plate on the side wall of the fence plate.
The fence gap blocking device has the advantages that the structure is simple, and the fence gap blocking effect can be effectively achieved; and the blocking device is installed after the bridge deck system is constructed, so that the construction is convenient, the durability is good, the replacement is convenient, the cost is low, and the bridge landscape is not influenced.

FIG. 1 is a schematic structural view of a vertical face of a blocking steel plate according to the present invention;
FIG. 2 is a schematic side view of the steel blocking plate according to the present invention;
fig. 3 is a schematic plan view of the blocking steel plate of the present invention.
Detailed Description
The specific technical scheme of the utility model is explained by combining the attached drawings.
As shown in fig. 1 to 3, the blocking device for the railing panel seam at the rail transit viaduct beam seam comprises a blocking steel plate 3, wherein the blocking steel plate 3 comprises a first plate and a second plate, and forms a structure with an L-shaped cross section;
the blocking steel plate 3 is tightly attached to the inner side of the breast board, and the first plate is fixed on the side surface of the breast board upright post 1;
the second plate of the blocking steel plate 3 is fixed on the side wall 2 of the breast board.
The first board of the steel blocking plate 3 is fixed on the side surface of the breast board upright post 1 through a plurality of first nail type anchor bolts 4, and a gasket is arranged between the first nail type anchor bolts 4 and the steel blocking plate 3.
The second plate of the blocking steel plate 3 is provided with a plurality of movable end bolt holes 5, and second nail type anchor bolts 7 are implanted into the movable end bolt holes 5 to fix the second plate on the side wall 2 of the breast board.
The prefabricated breast board is fixed in 6 tops on the bridge edge of a wing, adopts the vertical logical block steel sheet 3 that blocks that is "L" shape, is located to the breast board gap at roof beam seam to block. The longitudinal bridge length of the movable end bolt hole 5 needs to meet the requirement of the beam expansion amount. The width of the contact surface between the first plate of the blocking steel plate 3 and the fence upright post 1 is 100mm, and the width of the contact surface between the second plate and the fence side wall 2 is 150 mm. The corrosion prevention standard of the blocking steel plate 3, the first nail-type anchor bolt 4 and the second nail-type anchor bolt 7 is not lower than that of a first coating system in the railway steel bridge protective coating (TB/T1527), and the color of the finish paint is similar to that of concrete.
