Detailed Description

The technical solution of the present invention is described below with reference to the accompanying drawings and examples.

As shown in fig. 1 to 5, the connecting bridge structure of the two-body pressure-bearing boat of the present invention comprises a connecting bridge 1, wherein a plurality of transversely through strong beams 3 are arranged at the rib positions of the connecting bridge 1, a plurality of common beams 4 are additionally arranged between two adjacent strong beams 3, and a plurality of bottom sealing plates 5 are arranged at the bottom of the connecting bridge 1. The above constitutes the basic structure of the present invention.

The connecting bridge structure adopting the structure arrangement effectively improves the transverse bending resistance, the torsion resistance and the torsion load resistance of the connecting bridge structure, and can ensure that a vehicle can work safely and reliably when passing through the double-body pressure-bearing boat. When a vehicle passes through the bridge deck, the vehicle is in different positions, so that the connecting bridge structure is in a transverse bending, transverse twisting and bending twisting combined load state.

In this embodiment, a strong beam 3 transversely penetrates through each rib position of the connecting bridge 1, and the strong beam 3 transversely penetrates through the catamaran and penetrates through the inner side plates and the longitudinal bulkheads of the sheets. By adopting the structure, the strong cross beam 3 can better bear bending load caused by vehicle passing.

In the present embodiment, the strong cross beams 3 are continuous beams supported at the outer board, the inner board, and the longitudinal bulkheads of the blade body. By adopting the structure, the transversely through strong cross beam 3 can effectively transmit the vehicle load acting on the connecting bridge 1 to the sheet body of the double-body pressure-bearing boat, and the transverse bending resistance of the connecting bridge structure is effectively improved.

It should be noted that the rigidity of the sheet body is relatively large, the strong beam 3 is subjected to torsional constraint, and the strong beam 3 is transversely arranged in a penetrating manner, so that the stress concentration at the joint of the strong beam and the sheet body is relieved to some extent compared with the root of the cantilever beam, and the occurrence of structural damage accidents in the area is effectively avoided.

In this embodiment, 2 common beams 4 are additionally arranged between two adjacent strong beams 3. By adopting the structure, the width of the inner plate grid of the traffic lane is smaller than that of the wheel mark of the vehicle, so that the wheel mark load can be effectively transferred, and the safety and reliability of the local structure of the connecting bridge structure are improved.

It should be noted that 2 ordinary crossbeams 4 are additionally arranged between two adjacent strong crossbeams 3, so that the width of the plate grids in the lane is reduced to one third, the width of the plate grids is smaller than the width of the wheel marks, the wheel mark load can be effectively transmitted to at least two ordinary crossbeams 4, the damage accident caused by bearing the wheel marks by a single plate grid is effectively avoided, and the safety and reliability of the connecting bridge structure when heavy-load vehicles pass are ensured.

In this embodiment, the bottom both ends of connecting bridge 1 all are provided with 2 sets of end shrouding 5, and end shrouding 5 constitutes the antitorque case with the strong crossbeam 3 and the deck cooperation that link to each other. By adopting the structure, the torsion resistance of the connecting bridge structure is effectively improved.

It should be noted that, the bottom seal plates 5 are arranged at the two ends of the bottom of the connecting bridge 1, and two adjacent strong beams 3 are changed from an open section to a closed section, so that the characteristic of excellent torsion resistance of the closed section is fully exerted, and the torsion resistance of the connecting bridge structure of the double-body pressure-bearing boat is effectively improved; when a heavy-duty vehicle passes through the double-body pressure-bearing boat, even if a very unfavorable bending-twisting combined load working condition is formed, the connecting bridge structure still has enough bending-twisting load resistance, so that the safety of the pressure-bearing boat structure is guaranteed.

In practical application, the double-body pressure-bearing boats are connected with each other to form a boat bridge, the boat bodies are not only bridge legs, but also a bearing structure and a through-load bridge floor, when a vehicle passes through the bridge floor, the vehicle is positioned at different positions to cause the connecting bridge structure to be in different load conditions, and typical load conditions comprise transverse bending, transverse twisting, bending twisting combination and the like. Compared with the conventional connecting bridge structure of a catamaran ship, the connecting bridge structure provided by the invention has three differences, namely, each rib position is provided with a transverse through strong crossbeam 3, 2 common crossbeams 4 are additionally arranged among the strong crossbeams 3, and the end part of the connecting bridge 1 is provided with a bottom sealing plate 5. The working principle is as follows: the heavy-duty wheels of two opposite vehicles are all located on the double-body pressure-bearing boat connecting bridge 1, the connecting bridge 1 is mainly under the action of transverse bending load, and the transverse through strong cross beam 3 can effectively transmit the load acting on the connecting bridge 1 to the pressure-bearing boat sheet body, so that the structural damage caused by stress concentration is avoided. 2 ordinary crossbeams 4 are additionally arranged between the strong crossbeams 3, so that the width of the plate grids is effectively reduced, the wheel mark load can be effectively transferred, and the plate grids can be prevented from bearing the wheel mark effect and being locally damaged. Two subtend vehicle are central symmetry mode, are located the both sides lamellar body of binary pressure-bearing boat respectively, and rear portion heavy load wheel is close to overhanging board, and the connecting bridge structure mainly receives the horizontal load effect of turning round this moment, and connecting bridge 1 bottom seal board 5 forms closed structure with two strong crossbeams 3 and decking that link to each other this moment together, and the torsional strength of opening structure is far more, can effectively avoid the damage occurence of failure of connecting bridge structure under the horizontal load effect of turning round. When other vehicles are in different positions, the connecting bridge structure is under the action of bending and twisting combined load, the novel connecting bridge structure provided by the invention can effectively improve the bending and twisting load resistance of the connecting bridge structure, and effectively avoids the occurrence of damage accidents of the connecting bridge structure.

While the embodiments of the present invention have been described, the present invention is not limited to the above-mentioned embodiments, which are only illustrative and not restrictive, and those skilled in the art can make various modifications without departing from the spirit and scope of the present invention as defined by the appended claims.
