Abstract
A bridge deck waterproof structure of a steel truss bridge is characterized in that a longitudinal through long steel cover plate is arranged at the intersection position of a bridge deck system of the steel truss bridge and a main truss, two sides of the steel cover plate are welded with steel side plates, the steel side plates are welded on a top plate of the bridge deck system inside the main truss and a small girder of an outer cantilever of the truss in the bridge direction, a hole is formed in the position of a vertical web member and an inclined web member of the main truss by the steel cover plate, and waterproof putty is arranged for sealing. The utility model arranges the longitudinal through long steel cover plate at the intersection of the bridge deck system of the steel truss bridge and the main truss, so as to prevent rain sewage from permeating the positions of the lower chord and the lower chord node of the main truss; the steel cover plate is welded with the side plate, and the side plate is transversely welded on the deck top plate at the inner side of the main truss and the cantilever small longitudinal beam at the outer side of the truss in a bridging manner, so that the bridge deck is prevented from transversely seeping water from flowing into the positions of the lower chord and the lower chord node of the main truss; the steel cover plate is provided with holes at the positions of the vertical web members and the diagonal web members of the main truss, and waterproof putty is arranged for sealing, so that the requirements of small longitudinal and transverse displacement between the bridge deck system and the main truss are met, the installation is convenient, and the infiltration of rain sewage along the web wall is prevented.
Description
Technical Field
The utility model belongs to the technical field of the bridge of bridge attachment structural design technique and specifically relates to a steel truss bridge floor waterproof construction.
Background
The steel truss bridge is widely used in highway and municipal bridge engineering. The steel truss bridge truss is generally exposed outside, and according to the related experience of the old bridge of hundreds of years such as the roads and bridges in Zhejiang, Shanghai, the lower chord and the nodes thereof are easy to rust due to the accumulation of rain and sewage. Adopt this waterproof construction can effectually prevent that rain sewage from permeating to truss lower chord member and node in, and can guarantee the wholeness and the free elasticity of bridge floor structure, strengthen the durability and the aesthetic property of truss bridge structure.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a steel truss bridge floor waterproof construction can effectively prevent truss bridge lower chord member and lower chord node ponding corrosion.
In order to realize the purpose, the technical scheme of the utility model is that: a bridge deck waterproof structure of a steel truss bridge is characterized in that a longitudinal through long steel cover plate is arranged at the intersection position of a bridge deck system of the steel truss bridge and a main truss, two sides of the steel cover plate are welded with steel side plates, the steel side plates are welded on a top plate of the bridge deck system inside the main truss and a small girder of an outer cantilever of the truss in the bridge direction, a hole is formed in the position of a vertical web member and an inclined web member of the main truss by the steel cover plate, and waterproof putty is arranged for sealing.
Furthermore, stiffening plates are arranged inside the steel cover plate and the steel side plates at certain intervals to strengthen the structure.
Further, the construction method of the steel truss bridge deck waterproof structure comprises the following steps:
A. the steel cover plate, the steel side plate and the inner part are reinforced and welded into a whole;
B. one side steel side plate is welded with the bridge deck top plate on the inner side of the main truss, and the other side steel side plate is welded with the cantilever arm small longitudinal beam on the outer side of the main truss;
C. the intersection of the steel cover plate and the vertical web members and the diagonal web members of the truss is provided with a hole for the web members to pass through, and waterproof putty is arranged in the gap for sealing;
D. the waterproof cover plate is provided with landscape decoration and pedestrian leisure facilities.
The utility model has the obvious technical characteristics that the characteristics of the scheme are formed, firstly, a longitudinal through long steel cover plate is arranged at the intersection part of the bridge deck system of the steel truss bridge and the main truss, and rain sewage is prevented from permeating the positions of the lower chord and the lower chord node; secondly, welding a steel cover plate with a side plate, and welding a side plate transverse bridge direction on a deck top plate at the inner side of the main truss and a cantilever small longitudinal beam at the outer side of the truss to prevent the bridge deck from transversely accumulated water from flowing into the positions of a lower chord and a lower chord node of the main truss; thirdly, holes are formed in the steel cover plates at the positions of the vertical web members and the diagonal web members of the main trusses, and waterproof putty is arranged for sealing, so that the requirement of small longitudinal and transverse displacement between the bridge deck system and the main trusses is met, the installation is convenient, and rain sewage is prevented from permeating along the web wall; and fourthly, arranging landscape decoration and pedestrian leisure facilities on the waterproof cover plate, and enhancing the functionality and the landscape of the bridge structure.
Drawings
FIG. 1 is a schematic view of a waterproof structure of a steel truss bridge deck.
FIG. 2 is a second schematic view of a waterproof structure of a bridge deck of a steel truss bridge.
Reference numbers in the figures: the steel cover plate 1, the side plate 2, the stiffening plate 3, the waterproof putty 4, the bridge deck system top plate 5 on the inner side of the main truss, the truss outer cantilever small longitudinal beam 6, the cantilever arm 7, the main truss vertical web member 8 and the diagonal web member 9.
Detailed Description
The invention is further described with reference to the following figures and examples.
The utility model discloses a bridge deck waterproof structure of a steel truss bridge, wherein a longitudinal through long steel cover plate 1 is arranged at the intersection part of the bridge deck of the steel truss bridge and a main truss, the steel cover plate 1 is welded with a side plate 2, the side plate transverse bridge is welded on a bridge deck top plate 5 at the inner side of the main truss and a truss cantilever small longitudinal beam 6, holes are formed in the steel cover plate at the positions of a vertical web member 8 and an inclined web member 9 of the main truss, and waterproof putty 4 is arranged for sealing; stiffening plates 3 are arranged at a certain interval inside the cover plate 1 and the side plates 2 to reinforce the structure. The steel cover plate 1 can be provided with facilities such as landscape decoration, a leisure chair for pedestrians and the like.
This steel truss bridge deck waterproof construction can be used to highway and municipal bridge newly-built and rebuild the waterproof construction of steel truss bridge deck.
