Various bridge accessories such as railings and barriers can be easily attached directly welded to the deck.
Description
SPECIFICATION
STEEL DECK-FLANGE STRUCTURES
TECHNICAL FIELD OF THE UTILITY MODEL:
This utility model relates in general to a bridge structure and more particularly to a steel bridge deck structure which is used as road surface of the bridge .
BACKGROUND OF THE UTILITY MODEL :
Majority of the structural components of existing bridges such as girders and decks as road surface of the bridge are made of concrete materials with steel reinforcements. Some have steel girders and beams with concrete decks . This traditional types of constructions are too heavy and thus expensive to transport and lift and join together. Since time immemorial, this has been the practice except for some proprietary designs using built-up or composite steel as decks with stamped patterns or an overlay of asphalt to provide the rough skid-proof requirement for safety but these thin patterned steel with numerous stiffeners welded to it are not used to structurally reinforce the structure.
The use of steel as road riding surface is dangerous because at freezing temperatures, ice will readily form on the surface and pose danger to motorists. Due to this steel for road surfaces were not even considered in engineering codes and
practice . This, however, is not a problem in the tropical zones, but the practice pervades coupled by the prohibitively high cost of steel and the inadequacy of appropriate manufacturing technology before.
These drawbacks are overcame by using the superior quality of steel and the advanced technology in its processing. Using steel as a road riding surface (deck) and at the same time a major structural component as the flange is to a beam. Thus, it may be called "Deck-Flange" subject of this application . SUMMARY OF THE UTILITY MODEL:
It is therefore the object of this utility model to provide a steel bridge deck which can remedy the above-mentioned drawbacks of the traditional concrete bridge construction .
Another object of this utility model is to provide a steel bridge with a deck made of steel plates wherein steel plates or shapes are welded to the underside forming a beam structure and eliminating the use of concrete slabs and concrete girders resulting into a much less cost in constructing a bridge. Another object of this utility model is to provide a steel bridge deck -having the smooth deck plate provided with anti-skid means of the road surface thereof.
Still, another Object of this utility model is to provide a steel bridge deck which can be constructed into multiple lane of the road surface of the bridge by weldedly joining the edges of the plates by welding.
Further object of this utility model is to provide a steel bridge deck wherein bridge structural accessories such as rail guards can be weldedly connected thereto.
Other objects and advantages of this utility model will be fully understood upon reading the following detailed description taken in conjunction with the appended drawings, wherein:

Referring now to the drawings in detail wherein like reference numerals designate same parts throughout, there is shown the present utility model for a steel bridge deck generally designated by reference numeral 1 which is lightweight in structures compare to a concrete bridge.
Steel bridge deck 1 comprises a deck plate 2 which serves as the road surface of the bridge . As shown in Figure 1A, deck plate 2 is provided with a plurality of anti-skid means 3 on top thereof which serves as safety features for the vehicle particularly during rainy days . Anti-skid means 3 may consists of small flat welds . Anti-skid means 3 of small flat welds are formed preferably on top of deck plate 2 in diagonal in formation as shown in Figure 1A and Figure 1C. Anti-skid means 3 of small flat welds may be randomly formed on top of deck plate 2
alternatively as shown in Figure IB. However, any other kind of anti-skid means 3 may be used and/or provided on the deck plate 2.
Weldedly supporting the deck plate 2 is at least a steel girder 4 along the longitudinal direction of the bridge. As shown in Figure 1, steel girder 4 consists of first embodiment of a pair of I- type beam 4a. As shown in Figure 2, steel girder 4 consists of a second embodiment of a box-type beam 4b. As shown in Figure 3, steel girder 4 consists of a third embodiment of a truss-type beams 4c. These steel girders 4a, 4b, and 4c are structurally supported on piers 5. Steel deck plate 2 is likewise serves as top flange member of the steel girder 4.
As shown in Figure 4, steel deck plate 2 is weldedly joining another deck plate 2 along the longitudinal inner end thereof to form multiple lane of the road surface of a bridge. Deck plate 2 is provided with a downwardly sloping portion 6 towards the longitudinal outer end thereof which serves as path of rain water. Structural accessories of the bridge such as wheel guard, side rail 7 are directly welded to the deck plate 2. As shown in Figure 5, deck plate 2 can be easily repaired compare to damage concrete slabs. Another deck plate 2a can be directly welded on damage deck plate 2. As shown in Figure 6, two or more prefabricated deck plate structures 2 with girders 4 can be transported on construction site per delivery of the truck "T" compare to transporting of concrete girders and slabs thud reducing much transportation cost. As shown in Figure 7, a damage concrete bridge structures of an existing
bridge can be easily replaced by steel deck structures of the present utility model. After demolishing the damage concrete slabs and girders of an existing bridge, the steel bridge deck 1 of the present utility model can be easily installed by hoisting equipment "E" on existing pier or column 8,
