Abstract
The invention discloses a bridge plate which comprises a plurality of girders and a tensioning mechanism. The plurality of the girders in array are transversely disposed on a cross beam between bridge piers to form a bridge body and fixed through the tensioning mechanism. Compared with a conventional beam and slab structure in a pure reinforced concrete structure, since steel cables are superior to rebars in toughness and tensile strength, the bridge plate in the structure can bear higher shearing force brought by bridge load bearing, possibility of cross fracture of the bridge plate is greatly reduced, and bridge bearing capacity is improved.
Description
Technical field
The present invention relates to a kind of bridge board, belong to building field.
Background technology
The accident that the bridge board of viaduct fracture now or part are torn disengaging bridge main body gets more and more, be mainly because present bridge board mainly mixes earth monobloc cast by reinforcing bar, and the mixed adhesion deficiency of earth and the tightening force of cage of reinforcement not easily cause this type of accident.
Summary of the invention
The object of the invention is to: provide a kind of globality better, more stable bridge board structure.
The present invention realizes in the following way:
A bridge board, described bridge board comprises some body pillar and tensioning mechanism, forms the main body of bridge on the horizontal crossbeam between bridge pier of described some body pillar arrays, between described some body pillar, by tensioning mechanism, is fixed;
Described tensioning mechanism comprises wirerope, wirerope fixator, described wirerope annular is wound in the whole outside of some body pillar, between described some body pillar, there is gap, described wirerope fixator is arranged in gap, and the wirerope on described body pillar two sides is strained and fixed together by the wirerope fixator being arranged in gap;
Described wirerope fixator comprises two pitmans, combined block, described pitman one end is provided with the through hole for cross-under wirerope, the described pitman other end is provided with screw thread, and the screw thread of described two pitmans is that oppositely described combined block center is provided with the screwed hole matching with described screw thread.
As further innovation of the present invention, the cross section of described combined block is polygon.
A kind of construction method of bridge board, first some body pillar are being placed on the crossbeam between bridge pier, the some ring-type wireropes of winding on the whole in some body pillar, during winding, the wirerope on body pillar two sides is respectively through two through holes that are arranged on the wirerope fixator in gap, after winding, by turning the combined block of wirerope fixator, tension wirerope; Finally by cement, some body pillar are built to as a whole beam slab.
Beneficial effect:
The bridge board that the present invention passes through is built and is formed by some body pillar combinations, between body pillar, by wirerope, be wound around simultaneously and strain by wirerope fixator simultaneously, the beam slab of this spline structure is than the beam and slab structure of traditional clean steel tendon concrete structure, because the toughness of wirerope and pull resistance are better than reinforcing bar, so the bridge board of this structure can bear the higher shearing force of bringing due to bridge bearing, reduce greatly the possibility of bridge board transverse breakage, improve the bearing capacity of bridge.
Accompanying drawing explanation
Fig. 1 is generalized section of the present invention.
Fig. 2 is the structural representation of wirerope fixator.
In figure: 1, body pillar; 2, wirerope connector; 3, wirerope; 4, beam slab main body; 5, pitman; 6, combined block.
The specific embodiment
Below in conjunction with accompanying drawing, be described further:
As shown in Figure 1, the bridge board that the present invention is is built fixedly and is formed by some body pillar, the integral outer forming in some body pillar 1 is wound with wirerope 3, between when some body pillar 1 are placed on crossbeam, there is certain space, in space, be provided with wirerope connector 2, as Fig. 2, wirerope connector comprises two pitmans 5 that are provided with left-hand thread, pitman 5 is fixing by screw thread and combined block 6, wirerope 3 is when being wound around, wirerope 3 is respectively through being arranged on the wirerope through hole on pitman 5, after being wound around, passes through by wirerope 3 rotation combined block 6, pitman 5 shrinks, thereby tension wirerope 3, wirerope head is by wirerope connector 2, pitman 5 is screwed into the end of to wirerope 3 knottings are fixing,
Because body pillar of the present invention is strained by wirerope 3, because the toughness of wirerope and pull resistance are better than reinforcing bar, so the bridge board of this structure can bear the higher shearing force of bringing due to bridge bearing, reduce greatly the possibility of bridge board transverse breakage, improve the bearing capacity of bridge, bridge construction of the present invention can not make whole rapid fracture because of the fracture of top layer cement yet simultaneously, has higher safety.
