Problems solved by technology

At present, the temporary steel girders used for emergency repair of railway bridges mainly include Type 64 railway military beams, detachable truss girders and Type 87 emergency repair steel beams. The above-mentioned emergency repair steel beams are mainly used for emergency repair of ordinary railway bridges. Can they be directly used for The heavy-haul railway repair work needs further analysis, and the beam structure and bridge deck structure of the above-mentioned repair beam cannot be converted from a temporary structure to a permanent structure after the repair work is completed, and the permanent bridge structure needs to be demolished

specific Embodiment approach

[0018] The steel bridge deck structure that can be temporarily converted to permanent of the present invention, its preferred embodiment is:

[0019] The temporary structure of the bridge deck structure includes a base 1 and a support block 2, both of which are welded by steel plates to form a hollow structure, and the support block 2 is welded on the upper surface of the base 1, and each support block 2 is welded with two A screw rod 3 for installing a rail fastener, and concrete pouring holes 4 are respectively reserved on the base 1 and the support block 2;

[0020] After the concrete 14 is poured into the base 1 and the support block 2 through the concrete pouring hole 4, the bridge deck structure is converted from a temporary structure to a permanent structure.

[0021] The base 1 and the supporting block 2 are arranged with transverse stiffeners 5 and longitudinal stiffeners 6 respectively, and holes are left in the transverse stiffeners 5 and longitudinal stiffeners 6 ....

specific Embodiment

[0035] 1. Temporary deck structure stage

[0036] During the construction of the steel girder structure, the L-shaped steel plate 7 is pre-welded on the surface of the beam structure 12. After the construction of the beam structure 12 is completed, the bridge deck structure 13 is hoisted on the beam structure 12 by a crane, and the bridge deck structure 13 Use the L-shaped steel plate 7 to align it in place during hoisting. After the bridge deck structure 13 is in place, connect the beam structure 12 and the bridge deck structure 13 through the L-shaped steel plate 7, and finally install steel rails on the support blocks to form a temporary bridge deck structure. meet the conditions of access.

[0037] 2. Permanent bridge deck structure stage

[0038] In the construction stage of the permanent bridge, the existing temporary bridge deck structure is converted into a permanent bridge deck structure. Firstly, the bridge deck structure 13 and the beam structure 12 are welded into...

Abstract

The invention discloses a steel bridge deck structure capable of being changed into be a permanent structure from a temporary structure. A temporary structure of the deck structure comprises a base and a supporting block, wherein each of the base and the supporting base is welded into a hollow structure from a steel plate, the supporting block is welded on the upper surface of the base; two screwsfor mounting a steel rail fastener are welded on each supporting block; concrete filling holes are separately reserved in the base and the supporting block; and after concrete is filled into the baseand the supporting block through the concrete filling holes, the deck structure is changed into a permanent structure from a temporary structure. The steel bridge deck structure can quickly accomplish first-aid repair work of bridge deck structure parts of an overloaded railway, a high-speed railway and a common railway; at the permanent bridge construction stage, conversion between the temporarystructure and the permanent structure can be realized, and a later-stage construction period and later-stage workload of the permanent bridge are greatly shortened. The steel bridge deck structure ismainly applied to first-aid repair of deck structure parts while applied to first-aid repair of the overloaded railway, the high-speed railway and the common railway.

Description

technical field [0001] The invention relates to a railway emergency repair bridge deck structure, in particular to a temporary-to-permanent steel bridge deck structure. Background technique [0002] The railway emergency repair beam is mainly composed of two parts: the beam structure and the bridge deck structure. The bridge deck structure is installed on the beam structure, and the train directly acts on the bridge deck structure. At present, the temporary steel girders used for emergency repair of railway bridges mainly include Type 64 railway military beams, detachable truss girders and Type 87 emergency repair steel beams. The above-mentioned emergency repair steel beams are mainly used for emergency repair of ordinary railway bridges. Can they be directly used for The heavy-haul railway repair work needs further analysis, and the beam structure and bridge deck structure of the above-mentioned repair beam cannot be converted from a temporary structure to a permanent stru...
