The present invention is owing to having adopted above technical scheme, have significant technique effect: the present invention is by arranging flexible rubber ring at the connecting key connecting portion, can make connecting key and concrete collaborative variation, having reduced the concrete shrinkage stress heavily distributes, flexible rubber ring has increased the telescopicing performance of connecting key, to adapt to the shrinkage and creep of concrete in combining structure, avoid shrink cracks, improve the anti-fatigue performance of combining structure.
The accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention 1.
Fig. 2 is the front view of Fig. 1.
Fig. 3 is the structural representation of eversion type open pore steel plate.
The toponym that in above accompanying drawing, each number designation refers to is as follows: wherein 1-Wavelike steel webplate, 2-coupling, 3-concrete, 4-connection main part, 5-flexible rubber ring, 41-peg, 42-open pore steel plate, 43-hole, 61-otic placode that turns up, 62-remaining hole, 63-through hole.
The specific embodiment
Below in conjunction with accompanying drawing 1 to Fig. 3 and embodiment, the present invention is described in further detail:
Embodiment 1
Flexible rubber ring combining structure connecting key, as shown in Figure 1 to Figure 3, comprise Wavelike steel webplate 1, coupling 2, concrete 3, connect main part 4, concrete 3 be connected main part 4 and connect, connect main part 4 and coupling 2 welding, coupling 2 and Wavelike steel webplate 1 welding, connect on main part 4 and be enclosed with flexible rubber ring 5.
Connecting main part 4 is peg 41, and flexible rubber ring 5 is wrapped in the welding position of peg 41 and coupling 2.By in peg 41 and coupling 2 welding positions, flexible rubber ring being set, can make connecting key and concrete collaborative variation, having reduced the concrete shrinkage stress heavily distributes, flexible rubber ring has increased the telescopicing performance of connecting key, to adapt to the shrinkage and creep of concrete in combining structure, avoid shrink cracks, improve the anti-fatigue performance of combining structure.Connecting main part 4 is open pore steel plate 42, and flexible rubber ring 5 is socketed in the hole 43 of open pore steel plate 42.
The macromolecular compound that elastic gum snare 5 is vinyl, silica type or polyamine esters.Elastic gum snare 5 adopts the macromolecular compound with flexible vinyl, silica type or polyamine esters, can effectively improve the telescopicing performance of connecting portion, to adapt to the shrinkage and creep of concrete in combining structure, avoid shrink cracks, improve the anti-fatigue performance of combining structure.
Flexible rubber ring 5 cover length are 8 millimeters, and overlapping thick is 0.9 millimeter.Peg head of a nail place is end and middle part, and the energy cooperative transformation, therefore as long as the flexible space of root.Flexible rubber ring 5 is taper, be socketed in the peg root, when concrete amount of contraction is greater than the collaborative amount of contraction of unrestrained limit formula frange plate or concrete amount of contraction and lags behind the collaborative amount of contraction of unrestrained limit formula frange plate, reduce the root shearing force of peg, activity space while increasing the peg bending, ensure again peg and concrete switching performance simultaneously.
Coupling 2 is frange plate.Frange plate is with Lang limit, unrestrained limit formula frange plate, and formula frange plate both sides of the edge along its length, unrestrained limit are waveform.The wave height of formula frange plate both sides of the edge along its length, wave limit is for being less than 40 millimeters.The outermost end wave height of formula frange plate both sides of the edge along its length, wave limit is in 40 millimeters, and in the present embodiment, the wave height of formula frange plate both sides of the edge along its length, unrestrained limit is embodiment wave height 3.5mm.
Open pore steel plate 42 is the eversion type open pore steel plate, and the eversion type open pore steel plate comprises the otic placode 61 that turns up, and the otic placode 61 that turns up is to turn up and form after partly being cut by steel plate, leaves the remaining hole 62 that otic placode is routed up rear formation on steel plate, and the otic placode 63 that turns up is cast in concrete.Adopt the otic placode that directly turns up on steel plate, turn up the hole that reserves as concrete and run through the through hole of reinforcing bar, the steel plate turned up is again as the baffle plate of resisting shearing, whole connector does not adopt any welding and any auxiliary steel plate, has extremely strong fatigue resistance, shear resistance and good economy.
In a word, the foregoing is only preferred embodiment of the present invention, all equalizations of doing according to the present patent application the scope of the claims change and modify, and all should belong to the covering scope of patent of the present invention.
