Abstract
The utility model discloses an empty core plate girder construction for emptying core plate beam bridge, include the empty core plate roof beam that spanes the pontic, the bottom one end of sky core plate roof beam sets up single support, and the other end sets up two supports, and the bearing capacity of single individual support is two support bearing capacity sums of the other end, and the single support end of adjacent empty core plate roof beam is held to stagger with two supports and is arranged, the utility model discloses can avoid the veneer atress, improve the atress of slab and girder bridge, eliminate the empty core plate support disease of coming to nothing, guarantee the security and the durability of bridge.
Description
Technical field
The utility model belongs to Hollow Slab Beam Bridge technical field of construction, a kind of hollow slab beam structure for Hollow Slab Beam Bridge.
Background technology
In traditional hollow slab bridge girder construction, a piece of hollow slab girder is provided below 4 bearings, owing to bridge exists longitudinal gradient and horizontal wall inscription, due to site operation precision reason, four points are caused to be difficult to accomplish perfectly level, therefore after plate girder erection, due to four supporting-point injustice so that plate-girder unbalance stress, cause seat empty, plate-girder, by bending detrimental effect, causes a series of secondary disease.Field investigation by built bridge, there is seat empty disease in the blank board bridge having more than 50%, seat empty can cause cored slab single slab bearing, causes cored slab hinge seam and deck paving and cored slab itself to produce the cracking sick evil of grade, affects safety and the durability of structure.Tracing it to its cause, it is relevant that seat empty disease does not largely reach standard with the site operation precision of four-point supporting.Process for this disease at present is based primarily upon bridge field investigation, and mode of punishing after there is disease is complicated, and punishment cost is the highest.
Utility model content
The purpose of this utility model is to provide a kind of it can be avoided that single slab bearing, improves the stress of slab and girder bridge, eliminates cored slab seat empty disease, it is ensured that the security of bridge and the hollow slab beam structure for Hollow Slab Beam Bridge of durability.
The technical solution realizing the utility model purpose is:
A kind of hollow slab beam structure for Hollow Slab Beam Bridge, including the hollow slab girder across pontic, the bottom end of hollow slab girder arranges single bearing, the other end arranges two bearings, the bearing capacity of single bearing is two bearing bearing capacity sums of the other end, and the single support support end of adjacent hollow slab girder is staggeredly arranged with double support support end.
The utility model compared with prior art, its remarkable advantage:
(1) the utility model is by the bearing that two ting model bearings of former hollow slab girder one end are adjusted to relatively large number, four bearing supports making hollow slab girder original are adjusted to three bearing supports, leveling controls the bigger four-point supporting of difficulty be adjusted to leveling and be easily controlled stable three-point support, optimize the stress of plate-girder itself.
(2) supporting way of adjacent cored slab is replaced antisymmetry layout by the utility model, utilize the cast-in-place hinge seam between beam body or cast-in-place diaphragm that adjacent beam body is connected into entirety, while optimizing the stress of plate-girder itself, also optimize the overall stress between adjacent plate-girder.
(3) the utility model eliminates cored slab seat empty disease from thoroughly, fundamentally avoid single slab bearing, improve the stress of slab and girder bridge, strengthen the security of bridge, durability, save the maintenance cost of seat empty disease operation stage.
Below in conjunction with the accompanying drawings the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is that the utility model arranges side view for the structure of the hollow slab beam structure of Hollow Slab Beam Bridge.
Fig. 2 is that the utility model arranges top view for the structure of the hollow slab beam structure of Hollow Slab Beam Bridge.
Detailed description of the invention
In conjunction with Fig. 1 and Fig. 2:
A kind of hollow slab beam structure for Hollow Slab Beam Bridge of the utility model, including the hollow slab girder across pontic, the bottom end of hollow slab girder arranges single bearing, the other end arranges two bearings, the bearing capacity of single bearing is two bearing bearing capacity sums of the other end, and the single support support end of adjacent hollow slab girder is staggeredly arranged with double support support end.
Bearing is circular, and the bisector of two bearings of double support support end is through the center of circle of single support support end bearing.
Adjacent hollow slab girder is linked as entirety by cast-in-place strand seam.
Adjacent hollow slab girder is linked as entirety by cast-in-place diaphragm.
Embodiment 1:
In conjunction with Fig. 1 and Fig. 2:
A kind of hollow slab beam structure for Hollow Slab Beam Bridge, including the hollow slab girder across pontic, the bottom end of hollow slab girder arranges single bearing, the other end arranges two bearings, the bearing capacity of single bearing is two bearing bearing capacity sums of the other end, and the single support support end of adjacent hollow slab girder is staggeredly arranged with double support support end；Adjacent hollow slab girder is linked as entirety by cast-in-place strand seam.
Embodiment 2:
A kind of hollow slab beam structure for Hollow Slab Beam Bridge, including the hollow slab girder across pontic, the bottom end of hollow slab girder arranges single bearing, the other end arranges two bearings, the bearing capacity of single bearing is two bearing bearing capacity sums of the other end, and the single support support end of adjacent hollow slab girder is staggeredly arranged with double support support end；Wherein, bearing is circular, and the bisector of two bearings of double support support end is through the center of circle of single support support end bearing；Adjacent hollow slab girder is linked as entirety by cast-in-place diaphragm.
