It sets；For direction across bridge on the connecting plate of each upper anchor ear of bridge pier the same side, level sets up a spandrel girder, the spandrel girder and anchor ear
Welding at the top of connecting plate；Along bridge between two spandrel girders, setting up a distribution beam, every distribution beam two at spacing intervals
It is welded with the load-bearing top surface of the beam at end；In the distribution beam, a bowl buckle holder, each upright bar of the bowl buckle holder are set up
Lower end be supported in the distribution beam, in the upper end of the upright bar of bowl buckle holder, direction across bridge sets up the more lateral lumps of wood, described
At the top of the lateral lumps of wood, along bridge to one layer of longitudinal lumps of wood is laid with, formwork for placing is laid at the top of longitudinal lumps of wood.
It is identical as upper hooping structure further can to install one in the lower section of the upper anchor ear on each bridge pier for above-mentioned hoop bracket
Lower anchor ear, the bottom of each lower anchor ear is supported on the binder of board-like bridge, the connecting plate setting direction of lower anchor ear with upper armful
The connecting plate direction of hoop is consistent, is connected by a supporting rod between lower anchor ear and the connecting plate of upper anchor ear.
The utility model uses hoop bracket, and simple in structure, rod piece dosage is few, and temporary load(ing) is directly transmitted to pier stud, over the ground
Base is without any requirement；The mounting height of anchor ear can with pier stud height change, can meet lower section flood passage, navigation, do not stop requirement, keep away
The security risk caused by flood season construction obstruction river is exempted from.Hoop bracket operability is strong, construction is simple, conveniently, is showed
Board-like bridge superstructure construction is poured, prospective quality safety requirements has been reached.
Description of the drawings
It is anchor ear mounting means direction across bridge side view figure shown in Fig. 1；
Fig. 2 is the vertical view of anchor ear installation；
Fig. 3 is the direction across bridge structural schematic diagram of the utility model；
Fig. 4 is the suitable bridge of the utility model to structural schematic diagram.
Specific implementation mode
As shown in Figure 1 and Figure 2, the utility model is separately installed with one below the bent cap 1 of board-like bridge on each bridge pier 2
A upper anchor ear 3, each upper anchor ear 3 includes two and half circular boops, and the both sides of each half circular boop are equipped with connecting plate 31, two and half circular boops
To being buckled on bridge pier 2, the connecting plate 31 of two halves circular boop is bolted, and two semicircular band tightener is mounted on bridge pier；It is each
Mounting height of the upper anchor ear 3 on bridge pier 2 is consistent, and the connecting plate 31 of each upper anchor ear is along bridge to setting.
As shown in Figure 3, Figure 4, for direction across bridge on the connecting plate 31 of each upper anchor ear 3 of 2 the same side of bridge pier, level sets up one
It is welded at the top of spandrel girder 4, the spandrel girder 4 and anchor ear connecting plate；Along bridge between two spandrel girders 4, at spacing intervals
A distribution beam 5 is set up, every 5 both ends of distribution beam are welded with the load-bearing top surface of the beam；In the distribution beam 5, one bowl is set up
Detain holder 6, the lower end of each upright bar of the bowl buckle holder 6 is supported in the distribution beam, in the upright bar of bowl buckle holder
Upper end, direction across bridge set up more 7 lumps of wood of transverse direction, at 7 top of the lateral lumps of wood, along bridge to one layer of longitudinal lumps of wood 8 is laid with, in institute
It states and is laid with formwork for placing 9 at the top of longitudinal lumps of wood.
In a specific embodiment of the utility model, bent cap of the elevation of top away from board-like bridge of the upper anchor ear 3
Lower section 2.56-2.69m.
To ensure that upper anchor ear 3 is stablized in use, also one can be installed in the lower section of the upper anchor ear 3 on each bridge pier
The bottom of lower anchor ear 10 identical with upper hooping structure, each lower anchor ear 10 is supported on the binder 11 of board-like bridge, lower anchor ear
Connecting plate setting direction it is consistent with the connecting plate direction of upper anchor ear, between lower anchor ear and the connecting plate of upper anchor ear pass through one support
Bar 12 connects.I20a I-steel can be used in supporting rod between the lower anchor ear and upper anchor ear.
The utility model is when it is implemented, δ=16mm can be used in the upper anchor ear, thickness Q235 steel plates roll, diameter
