Abstract
The utility model discloses a staggered expansion joint structure for a bridge sidewalk structure. The staggered expansion joint structure comprises a structure breaking joint and an expansion joint longitudinally staggered with the structure breaking joint, wherein the expansion joint longitudinally staggered with the structure breaking joint is formed in a way that a structure on one side of the structure breaking joint locally and longitudinally extends across a structure breaking joint to be overlapped with the structure on the other side. According to the staggered expansion joint structure, an expansion joint body is formed by an end part overlapping structure for the two structures of the expansion joint, an expansion joint filler pavement can directly transmit passenger loads to a lower component of the overlapping structure when the loads are born, and the staggered expansion joint structure is a non-beam stress working component, so that the expansion joint filler pavement is difficult to damage, the stress condition of the whole expansion joint structure is improved, the bearing capacity of the expansion joint filler pavement is improved, and the service cycle of the expansion joint filler pavement is prolonged; due to the adoption of the structure, the width of the expansion joint is greatly increased, and the deformation range of the expansion joint is greatly widened without reduction in the bearing capacity.
Description
Technical field
The utility model relates to a kind of accessory structure of field of civil engineering, particularly a kind of pedestrian way of bridge structure dislocation expansion joint structure.
Background technology
Shrinkage joint produces distortion for adapting to the buildings such as road and bridge for field of civil engineering under many factors (variations in temperature, creep deformation, load action, uneven settlement of foundation and earthquake) effect, avoids cracking even to destroy and the stretching device of the artificial Oil pipeline breaking joint arranging.
Shrinkage joint is between adjacent structure, and particularly, in bridge construction, the shrinkage joint joint technique between adjacent structure is very universal.For the expanded joint structure of pedestrian way of bridge, not high to supporting capacity requirement, thereby generally adopt the mode of directly filling thermoplastic filler, and there is certain elastic deformation, can be adapted to the distortion at shrinkage joint.
But because above-mentioned thermoplastic filler integral body is positioned at directly over structure breaking joint, less stable, easily subsides and lost efficacy, application life and intact cycle are not ideal enough; Such as, existing cutting seam type shrinkage joint is at abutment and girder seam crossing, during by construction, the acute seam formation of reserved structure breaking joint or later stage, generally adopts plank or the filling of tetrafluoroethene plate, by the distortion of plank or tetrafluoroethene plate, adapts to the flexible of shrinkage joint; Although this expansion joint structure is simple, easy construction, plank can be used as especially template and uses when construction, under the long-time immersion of rainwater and temperature action, plank or the easy burn into of tetrafluoroethene plate come off, form cavity, easily by foreign body obstruction, make shrinkage joint lose Telescopic.
Therefore, need to, to the improve force-bearing situation of whole expansion joint structure of the expansion joint structure of pedestrian way of bridge, improve the supporting capacity after Expansion Joint filler is mated formation, the life cycle that extends expansion gap device.
Utility model content
In view of this, the purpose of this utility model provides a kind of pedestrian way of bridge structure dislocation expansion joint structure, improves the force-bearing situation of whole expansion gap device, improves the supporting capacity after Expansion Joint filler is mated formation, and extends the life cycle of mating formation in shrinkage joint.
Pedestrian way of bridge structure dislocation expansion joint structure of the present utility model, comprise structure breaking joint and the shrinkage joint longitudinally misplacing with structural sections seam, described and structural sections seam is longitudinally overlapped and is formed by structure breaking joint one side structure part longitudinal extension Oil pipeline breaking joint and opposite side structure in the shrinkage joint of dislocation.
Further, described shrinkage joint has filler paving structure;
Further, form one of them end of structure breaking joint structure on two sides and form the sinking step along shrinkage joint width, another structural top extends to form extension side walk slab and is overlapped in this sinking step surface, described shrinkage joint is at sinking step sidewall and extend the spacing between side walk slab end, and wherein structure breaking joint covers by extending after side walk slab is overlapped in sinking step;
Further, filler paving structure is paved on the step sidewall of sinking step and extends between side walk slab end;
Further, one of two structures that form shrinkage joint are the parapet I on abutment, and another is the parapet II on bridge main beam, and described sinking step is formed in parapet I, extend side walk slab and are formed at parapet II;
Further, the side walk slab of bridge is overlapped on respectively the side walk slab that parapet I and parapet II form and sinks on step;
Further, described filler paving structure is thermoplastic filler paving structure the step surface that is supported in sinking step.
The beneficial effects of the utility model: pedestrian way of bridge structure dislocation expansion joint structure of the present utility model, adopt the expanded joint structure longitudinally misplacing with structural sections seam, realized longitudinal dislocation of the shrinkage joint of structural performance weakness and weak bridge construction breaking joint position, during bearing load, Expansion Joint filler is mated formation and Pedestrian Load can be directly passed to the lower member of its lower bridging arrangement, for the stressed working component of non-beam type, the vulnerability of structure disease of avoiding shrinkage joint, sidewalk to overlap with bridge construction breaking joint and producing, power transmission is reliable, structure is durable, avoided traditional shrinkage joint to destroy the zanjon effect that overlaps with bridge construction breaking joint and produce, sidewalk perception and pedestrains safety are had to reliable guarantee, avoid traditional sidewalk Expansion Joint filler to drop or the susceptible disease such as steel deck-plate warpage evil, improved the force-bearing situation of whole expansion joint structure, improved the supporting capacity of mating formation in shrinkage joint, extended the life cycle of mating formation in shrinkage joint, the simple structure at structure of sidewalk dislocation shrinkage joint, functions are clear and definite, structural performance reliable durable, safeguard simple and convenient, owing to thering is said structure, make shrinkage joint width and deformation range there is larger lifting, do not reduce supporting capacity.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is the utility model structural representation;
Fig. 2 is the top view of Fig. 1.
The specific embodiment
Fig. 1 is the utility model structural representation, Fig. 2 is the top view of Fig. 1, as shown in the figure: the pedestrian way of bridge structure dislocation expansion joint structure of the present embodiment, comprise structure breaking joint 8 and the shrinkage joint longitudinally misplacing with structural sections seam, the described shrinkage joint longitudinally misplacing with structural sections seam 8 is formed by structure breaking joint one side structure 4 local longitudinal extension Oil pipeline breaking joint and opposite side structure 2 overlap joints, and described shrinkage joint has filler paving structure 3; Extend across rear formation and be superimposed with each other along the vertical direction between the two, and have ledge structure, wherein a side can be born mutually downward pressure and opposite side is formed and supported; Bridging arrangement forms expanded joint structure, need to make the both sides after overlap joint be reserved with necessary width spaces, easily forms shrinkage joint extendable room.
