Abstract
The utility model relates to a connecting structure for bridge segments. At present, precast segments of bridges are generally connected through pouring concrete in wet joints or coating dry joints with epoxy glue in and tensioning prestress, and the structural tension is mainly born by reinforcements or prestressed reinforcements. The connecting structure is spliced by two adjacent sections of RPC (reactive powder concrete) longitudinal beams, precast steel plates are arranged at ends of the RPC longitudinal beams, and bolt holes are formed in the precast steel plates; after the two adjacent sections of RPC longitudinal beams are spliced, node plates are transversely arranged on two sides of longitudinal beam joints, and bolt holes are formed in the node plates; bolts penetrate through the node plates on two sides to splice and fix the two adjacent sections of RPC longitudinal beams; and the precast steel plates are U-shaped steel plates and cover the ends of the RPC longitudinal beams from the side of end surfaces of the RPC longitudinal beams. The connecting structure for the bridge segments adopts an RPC beam segment splicing manner, the structural tension is not born by the reinforcements or the prestressed reinforcements any more, and the connecting structure is simple in structure, clear in stress, novel in material, good in mechanical performance and higher in durability.
Description
Technical field
the utility model belongs to bridge construction technical field, is specifically related to a kind of bridge subsection syndeton.
Background technology
The bridge subsection syndeton of steel concrete or prestressed reinforced concrete construction, between its prefabricated subsection, the general seam concreting mode that wets that adopts connects, or adopt stem grafting seam to smear epoxy glue stretch-draw prestressing force connection again, in these connected modes, structure tension is mainly born by reinforcing bar or prestressed reinforcement, weight concrete is large, and operating expenses is high.
RPC (reactive powder concrete, RPC), is to take fine sand as aggregate, mixes a large amount of silicon ashes and waits mineral admixture, high efficiency water reducing agent and micro steel fiber, the concrete material of a kind of high strength of formation, high tenacity, low porosity.Compare with general concrete, rejected coarse aggregate (stone), needn't configuration reinforcement or prestress wire, be the high performance concrete that DSP material and fiber reinforced material are composited.
Summary of the invention
The purpose of this utility model is to provide the assembled bridge subsection syndeton of a kind of RPC of being applicable to girder segment.
The technical scheme that the utility model adopts is:
A bridge subsection syndeton, is spliced by adjacent two joint RPC longerons, it is characterized in that:
Described RPC longeron end is provided with pre-embedded steel slab, on pre-embedded steel slab and RPC longeron correspondence position, is provided with bolt hole;
After adjacent two joint RPC longeron splicings, longeron seam both lateral sides is provided with gusset plate, and on gusset plate, correspondence is provided with bolt hole;
Bolt is fixing by adjacent two joint RPC longeron splicings through both sides gusset plate.
Described pre-embedded steel slab is " Qian " font steel plate, from RPC longeron end face side parcel RPC longeron end.
The utlity model has following advantage:
The utility model is the bridge subsection syndeton for RPC girder segment erection method, does not rely on reinforcing bar or prestressed reinforcement and bears structure tension, simple in structure, stressed clear and definite, material is novel and mechanical property good, durability is better.
Accompanying drawing explanation
Fig. 1 is the utility model elevation.
Fig. 2 is the utility model plan view.
Fig. 3 is the utility model side view.
Fig. 4 is RPC longeron end drawing.
In figure, 1-RPC longeron, 2-gusset plate, 3-longeron seam, 4-bolt, 5-pre-embedded steel slab.
The specific embodiment
Below in conjunction with the specific embodiment, the utility model is described in detail.
A kind of bridge subsection syndeton that the utility model relates to, it is the bridge subsection syndeton for RPC girder segment erection method, by adjacent two joint RPC longeron 1 splicings, the long 500cm of RPC longeron 1 * wide 22cm * high 110cm, RPC longeron 1 end is provided with pre-embedded steel slab 5, on pre-embedded steel slab 5 and RPC longeron 1 correspondence position, is provided with bolt hole; After adjacent two joint RPC longeron 1 splicings, longeron seam 3 both lateral sides are provided with gusset plate 2, and on gusset plate 2, correspondence is provided with bolt hole; Bolt 4 is fixing by adjacent two joint RPC longeron 1 splicings through both sides gusset plate 2.Pre-embedded steel slab 5 is " Qian " font steel plate, and thickness 1cm, from RPC longeron 1 end face side parcel RPC longeron 1 end.
Specific construction step of the present utility model is as follows:
1, longeron merogenesis is prefabricated in the factory, and notes the built-in fittings such as pre-buried gusset plate steel plate, reserved high-strength bolt hole, connecting bolt, after longeron Ying factory examination amalgamation lattice, transports scene to.
2, on-the-spot splicing longeron, installs gusset plate and high-strength bolt.
The utility model adopts RPC as girder material, and by RPC bridge subsection girder, the mode with high-strength bolt connects first, with the girder that high-strength bolt gusset plate connects, not steel work but RPC structure (high-strength bolt gusset plate is generally used for the connection between steel), can make full use of the tensile property of RPC.
It is cited that content of the present utility model is not limited to embodiment, and the conversion of any equivalence that those of ordinary skills take technical solutions of the utility model by reading the utility model manual, is claim of the present utility model and contains.
Claims (2)
