Description
Technical field
This utility model belongs to science of bridge building field, relates to prefabricated concrete bridge and pre-manufactured steel concrete combined structure bridge
Connect, especially prefabricated bridge interconnection technique.
Background technology
In existing packaged type bridges, the conventional connected mode between prefabricated bridge floor is: it is upper and lower that two pieces of prefabricated bridges stretch out
Ceng Ge road reinforcing bar interlaced arrangement, each road reinforcing bar of two pieces of prefabricated bridges mutually overlaps, at the scene by levels in lengthwise position
The mutually reinforcement welding of overlap joint gets up, and then the place two pieces of prefabricated bridge seams pours concrete, complete after maintenance
Become to connect.But there is problem below in this prefabricated bridge connected mode:
1, in order to prevent the cracking of composite bridge concrete slab, in concrete slab, the spacing of reinforcing bar is generally the least, reinforcing bar straight
Footpath is the biggest, when connecting two pieces of prefabricated bridges, it is desirable to each road longitudinal reinforcement interlaced arrangement of two pieces of prefabricated bridges,
Little yet with bar spacing, bar diameter is big, and working place becomes the narrowest and small, be by each road steel bar welding of levels
Picking up, difficulty is bigger.
2, the reinforcing bar of each road interlaced arrangement of prefabricated bridge should weld, narrow and small due to space, and the reinforcing bar of levels is usual
Single welding can only be carried out, and a lot of owing to affecting the factor of welding quality of reinforcing steel, such as voltage, weather, environment, execute
Work condition and operation level etc., welding quality is difficult to be guaranteed.
3, will weld at the scene due to the levels reinforcing bar of two pieces of prefabricated bridge interlaced arrangement, cost puts into comparatively speaking
Higher, the most on-the-spot construction is also affected by weather and weather etc., and therefore the duration is difficult to be controlled.
4, the place of two pieces of prefabricated bridge connections is usually located at the pier top of bridge, is in hogging moment area, at floorings at pier top
In tension state.Little yet with the spacing between floorings reinforcing bar, welding operation space is the least, can only be by levels
Reinforcing bar uses single welding simply to couple together, and many times due to the restriction in space, lower floor's reinforcing bar can not be soldered to, and
Simple colligation couples together, and this connected mode is highly vulnerable to breakage under a stretching force, and the weld seam of reinforcing bar is easily torn,
Thus cause Joint failure.
Visible, develop a kind of novel floorings connected mode and have ten for the construction of packaged type bridges and the raising of stress performance
Divide important meaning.
Utility model content
For existing prefabricated bridge connected mode construction inconvenience in packaged type bridges, connect insecure defect, this practicality
Novel purpose is to provide a kind of novel prefabricated bridge attachment structure, can be widely applied to the connection of precast concrete bridge,
The connection of concrete slab in composite bridge, connects relatively reliable compared with existing floorings method of attachment, and bearing capacity is higher,
Easy construction, it is simple to improving speed of application, quality is also readily obtained control.
In order to achieve the above object, this utility model is by the following technical solutions:
A kind of prefabricated bridge attachment structure of band arched ribs, including: the prefabricated bridge of two pieces of band arched ribs；Some transverse steels；
Each road reinforcing bar interlaced arrangement in the vertical of two pieces of prefabricated bridges, each road reinforcing bar on upper strata forms one section of overlapping regions in the vertical,
The segmental arc of each road reinforcing bar of lower floor intersects in the vertical；Each road reinforcing bar on upper strata is fixedly connected with in the region of mutually overlap joint
Coming, each road reinforcing bar of lower floor is coupled together by colligation, interspersed upper transverse steel between the reinforcing bar of upper and lower layer.
Further, the reinforcing bar on described upper strata is straight, and one end of reinforcing bar is embedded in concrete component, and the other end extends concrete
Component one segment length.
Reinforcing bar one end of described lower floor is straight, and the other end is arc, and straight one end is embedded in concrete component, band arc
Concrete component is extended in one end, and the end of arc is bent up the lower edge to top bars.
The concrete section of the reinforcing bar protruding side of prefabricated bridge is from the side in " bracket shape ".
The reinforcing bar on upper strata extends from the upside on " bracket shape " concrete section slope, and the reinforcing bar of lower floor mixes from " bracket shape "
The downside of solidifying soil cross-section slope is extended.
Described fixing connection is welding.
Owing to have employed such scheme, this utility model has the advantages that
The mode of the reinforcing bar colligation of lower floor replaces the mode of welding to couple together, and operates convenient in less space,
Speed of application, and then reduction of erection time can be improved.
Lower floor's reinforcing bar upwards bends up supreme layer reinforcing bar lower edge, forms the frame closed, and two frames of two prefabricated bridges are in the vertical
Interlaced, outside levels reinforcing bar, put transverse steel, the bearing capacity of bonding pad after pouring concrete, can be improved.
