Description

Technical Field

[0001] This invention relates to a composite steel bridge deck structure and its paving method, belonging to the field of composite steel bridge construction technology. Background Technology

[0002] Steel bridges are bridges constructed primarily of steel. They are characterized by high strength and rigidity, and compared to concrete bridges, they allow for reductions in beam height and self-weight. Currently, most existing bridges utilize a spliced ​​steel beam structure for their decks.

[0003] For example, patent application number CN202121376850.3 discloses a heavy-duty bridge deck for steel bridges. It includes two layers of bridge decks, one above the other. Each bridge deck includes multiple first I-beams spaced longitudinally and multiple second I-beams positioned between adjacent first I-beams. The second I-beams between adjacent first I-beams are spaced laterally, and the length of each first I-beam is greater than the length of the second I-beams. Multiple channel steels are positioned between adjacent first I-beams in the upper bridge deck. The bridge deck provided by this invention has two layers, which improves the overall structural stability of the heavy-duty bridge deck, extends its service life, and prevents it from easily bending or deforming during use. Furthermore, the second I-beams are fixed between adjacent first I-beams, not only providing a secure connection between the multiple first I-beams but also ensuring the extreme stability of the heavy-duty bridge deck structure.

[0004] While the aforementioned patent can achieve the supporting function of steel bridge decks and has the advantage of easy bridge deck construction, the current technology is not comprehensive and has the following drawbacks: the disadvantages are that it relatively increases the amount of steel used and makes it difficult to standardize the factory manufacturing of steel bridge decks.

[0005] To solve one of the above problems, there is an urgent need for a composite steel bridge deck structure and its paving method that is reliable in quality, easy to construct, and has a relatively low overall cost. Summary of the Invention

[0006] In view of the shortcomings of the prior art, the technical problem to be solved by the present invention is: how to meet the requirements of reliable bridge deck quality, convenient construction and relatively low overall cost of composite steel bridge deck, and to this end, a composite steel bridge deck structure and its paving method are provided.

[0007] The composite steel bridge deck structure of the present invention includes a base plate, which is a rectangular steel plate. The base plate has multiple spaced reinforcing support beams on its upper surface, each beam being parallel to a set of sides of the base plate. Adjacent sets of reinforcing support beams are detachably connected by multiple sets of spaced inter-beam connectors. Multiple sets of pre-embedded vertical reinforcing bars are welded to the upper surface of the base plate, each set passing through the space between adjacent sets of inter-beam connectors. Pre-embedded horizontal reinforcing bars A are installed on the upper surface of the reinforcing support beams via horizontal reinforcing bar mounting seats. Multiple sets of pre-embedded horizontal reinforcing bars B, interleaved with the pre-embedded horizontal reinforcing bars A, are arranged on the upper surface of the pre-embedded horizontal reinforcing bars A. The pre-embedded horizontal reinforcing bars A and B are bundled together to form a reinforcing mesh structure. The reinforcing support beams, inter-beam connectors, pre-embedded vertical reinforcing bars, horizontal reinforcing bar mounting seats, pre-embedded horizontal reinforcing bars A, and pre-embedded horizontal reinforcing bars B are all pre-embedded in the concrete layer on the upper surface of the base plate.

[0008] Preferably, the reinforcing support beam includes a rectangular tubular structure enclosed by a top plate, a left side plate, a right side plate, and a bottom plate. The bottom plate of the reinforcing support beam is fitted to the upper surface of the bottom plate. The left side plate and the right side plate of the reinforcing support beam are respectively provided with grooves A along their length for installing inter-beam connectors. The top plate of the reinforcing support beam is provided with grooves B along its length for installing pre-embedded horizontal reinforcing bars A.

[0009] Preferably, two layers of sliding grooves A are provided at intervals on the left and right sides, and a set of beam connectors are assembled on each set of sliding grooves A to connect two sets of adjacent reinforcing support beams together.

[0010] Preferably, the beam connector includes a hollow flat tube with an internal support strip inside. The internal support strip divides the inner cavity of the flat tube into a first cavity and a second cavity. A set of left and right sliders that cooperate with the corresponding sliding groove A are respectively provided on the two sides of the flat tube.

[0011] Preferably, the beam connector is made of metal or plastic, and the flat tube, internal support strip, left slider and right slider are integrally formed.

[0012] Preferably, the slide groove A includes an upper slide groove plate and a lower slide groove plate arranged opposite each other along the length direction of the left or right side plate. The upper and lower slide groove plates form a slide groove with an opening, and the left or right slider is located in the slide groove and can slide along the length direction of the slide groove.

[0013] Preferably, the horizontal rebar mounting base includes parallel side plates A and B. One end of side plates A and B is connected together by a top-layer connecting pipe. The other end of side plates A and B is respectively provided with outwardly bent portions A and B. The middle parts of side plates A and B are connected together by a middle-layer connecting plate. A connecting screw is threaded onto the middle-layer connecting plate. One end of the connecting screw is set as a plane that abuts against the top plate, and the other end is provided with a slotted thread. A through hole coaxial with the connecting screw is opened on the top-layer connecting pipe. The connecting screw can be disassembled by using a screwdriver through the through hole and engaging with the slotted thread. The pre-embedded horizontal rebar A passes through multiple sets of top-layer connecting pipes that are on the same straight line.

[0014] Preferably, the chute B includes a left chute plate and a right chute plate arranged opposite each other along the length direction of the top plate. The left chute plate and the right chute plate form a chute with an opening. The bent portion A and the bent portion B are located within the chute and can slide along the length direction of the chute. This invention also discloses a method for paving a composite steel bridge deck structure, characterized in that a base plate is placed on a cement vibration table, and then multiple sets of reinforcing support beams are placed on the upper surface of the base plate. Adjacent reinforcing support beams are connected together using beam connectors. Pre-embedded vertical steel bars are installed in the gap between the two sets of beam connectors, and the bottom ends of the pre-embedded vertical steel bars are welded to the upper surface of the base plate. On each set of base plates, multiple sets of horizontal steel bar mounting seats are installed using the chute B on the base plate. Pre-embedded horizontal steel bars A can pass through the top connecting pipe. The same pre-embedded horizontal steel bar A is installed on the same reinforcing support beam through the horizontal steel bar mounting seat. The length direction of the reinforcing support beam is consistent with that of the pre-embedded horizontal steel bar A.

[0015] Secondly, a retaining plate is welded around the base plate, and a pre-embedded horizontal steel bar B is welded onto the pre-embedded horizontal steel bar A. The pre-embedded horizontal steel bars A and B are tied together to form a steel mesh structure. Finally, concrete is poured into the area enclosed by the base plate and the retaining plate, and the concrete is vibrated on a cement vibrating table. After the concrete has solidified, the reinforcing support beam, beam connectors, pre-embedded vertical steel bars, horizontal steel bar mounting bases, pre-embedded horizontal steel bars A, and pre-embedded horizontal steel bars B are all pre-embedded in the concrete layer on the upper surface of the base plate.

[0016] Preferably, the horizontal steel bar mounting seat is inserted from one end of the slide groove B and locked with connecting screws. Both slide groove A and slide groove B can be distributed in multiple segments.

[0017] Preferably, the reinforcing support beam and the horizontal steel bar mounting base are both made of metal.
