The supporting structure of the overpass superstructure comprises an overpass middle pier and an overpass end pier arranged at one end far away from an overhead station hall, the supporting structure also comprises overhanging brackets arranged near the end far away from the overhead station hall, the overhanging ends of the overhead station hall layer prestressed bent cap are fixedly provided with sealing reinforced concrete sealing beams vertical to the overhanging ends, the overhanging brackets are fixedly provided on the outer side wall of the reinforced concrete sealing beams, and reinforced concrete cushion blocks for installing overpass supports are transversely arranged at intervals on the top surfaces of the overhanging brackets.
Description
Technical Field
The utility model relates to rail transit, in particular to an overhead station hall layer overpass bracket support structure.
Background
In the construction of urban rail transit in China, subway lines in suburban areas are mostly constructed in a ground viaduct mode, and corresponding stations adopt ground overhead stations. The overhead station is connected with the personnel entrance and the station hall layer through the overpass. The overpass adopts steel construction overpass more, and when the bridge span was great, it sets up the pier to need in overpass both ends and centre, sets up the overpass support above the pier.
One end of the overhead station hall layer of the overhead bridge can be additionally provided with a pier, and an overhead bridge support is arranged on the additionally provided pier. The structure is technically simple and feasible, but the construction cost and the construction period are increased.
Disclosure of Invention
The utility model aims to solve the technical problem of providing an overhead station hall layer overpass bracket support structure so as to greatly reduce the construction cost and construction period of the overpass and avoid independently arranging a pier as the overpass support.
The technical scheme adopted for solving the technical problems is as follows:
the utility model relates to an overhead station hall layer overpass bracket support structure, wherein a supporting structure of an overpass upper structure comprises an overpass middle pier and an overpass end pier arranged at one end far away from an overhead station hall, and the overhead station hall layer overpass bracket support structure is characterized in that: the supporting structure further comprises overhanging brackets which are arranged close to the end far away from the overhead station hall, the overhanging ends of the overhead station hall layer prestressed bent cap are fixedly connected with sealing reinforced concrete sealing beams which are vertical to the overhanging ends of the overhead station hall layer prestressed bent cap, the overhanging brackets are fixedly arranged on the outer side wall of the reinforced concrete sealing beams, and reinforced concrete cushion blocks for installing the overpass support are transversely arranged on the top surfaces of the overhanging brackets at intervals.
The utility model has the beneficial effects that the overhanging end of the prestressed bent cap of the overhead station hall layer is fixedly provided with the sealing reinforced concrete sealing beam, and the overhanging bracket is arranged on the sealing reinforced concrete sealing beam, so that the condition that a pier is independently arranged as an overpass support is avoided, and the construction cost and construction period of the overpass can be greatly reduced; the structure is simple, the force transmission path of the structure is clear, and the construction is convenient.
Drawings
The specification includes four drawings as follows:
FIG. 1 is a schematic diagram of the position relationship between the bracket support structure of the overpass in the standing hall of the overhead station and the overpass;
FIG. 2 is a plan view of an overhead standing hall level overpass bracket support configuration of the present utility model;
FIG. 3 is a cross-sectional view of an overhead standing room level overpass bracket support configuration of the present utility model;
FIG. 4 is a block reinforcement construction diagram of an overhead station hall layer overpass bracket support construction;
the components and corresponding indicia are shown: the bridge comprises a prestressed capping beam 1, a reinforced concrete sealing beam 2, overhanging brackets 3, reinforced concrete cushion blocks 4, a bottom outer edge 5, inverted U-shaped steel bars 6, bridge piers 7 at the end of an overpass, bridge piers 8 in the middle of the overpass and a overpass superstructure 9.
Detailed Description
The utility model will be further described with reference to the drawings and examples.
Referring to fig. 1, 2 and 3, the supporting structure of the overpass bracket support of the hall of the overhead station of the present utility model, the supporting structure of the overpass superstructure 9 comprises an overpass middle pier 8 and an overpass end pier 7 arranged at one end far from the hall of the overhead station. The supporting structure further comprises overhanging brackets 3 which are arranged close to the end far away from the overhead station hall, the overhanging ends of the overhead station hall layer prestressed bent cap 1 are fixedly connected with sealing reinforced concrete sealing beams 2 which are vertical to the overhanging ends, the overhanging brackets 3 are fixedly arranged on the outer side walls of the reinforced concrete sealing beams 2, and reinforced concrete cushion blocks 4 for installing the overpass support are transversely arranged on the top surfaces of the overhanging brackets 3 at intervals. The bridge pier is prevented from being independently arranged as an overpass support, the construction cost and construction period of the overpass can be greatly reduced, and the bridge pier has the characteristics of simple structure, clear structural force transmission path and convenience in construction.
Referring to fig. 3, the width of the cantilever bracket 3 is larger than the width of the upper structure 9 of the overpass, the cantilever length is 200mm longer than the length of the overpass support, and the outer edge 5 of the bottom of the cantilever bracket 3 is provided with a 45-degree bevel angle. Referring to fig. 4, the reinforced concrete cushion block 4 is larger than the rubber support of the overpass, the top of the cushion block is internally provided with inverted U-shaped steel bars 6 with local bearing function at intervals, and the lower part of each inverted U-shaped steel bar 6 extends into the cantilever bracket 3.
The utility model discloses an implementation step of an overhead station hall layer overpass bracket support structure, which comprises the following steps:
a. constructing an overhead station hall layer prestress bent cap 1, constructing a sealing reinforced concrete sealing beam 2 at the end part of the overhead station hall layer prestress bent cap 1, and solidifying the two into a whole;
b. constructing overhanging bracket 3 on the outer side wall of sealing reinforced concrete sealing beam 2, and consolidating the two together, wherein 45-degree bevel angle 4 is arranged at outer edge 5 of bottom of bracket 3;
c. constructing reinforced concrete cushion blocks 4 on the top surfaces of the overhanging brackets 3, and arranging inverted U-shaped steel bars 6 with lower parts extending into the overhanging brackets 3 at intervals in the tops of the reinforced concrete cushion blocks 4;
d. and constructing an overpass end pier 7 and an overpass middle pier 8, constructing an overpass upper structure 9, and installing the overpass upper structure 9 on the overpass end pier 7, the overpass middle pier 8 and the cantilever bracket 3.
