Abstract
The utility model relates to a transitional connecting device between connecting keys, and discloses an elastic rubber ring connecting key for a composite structure. The elastic rubber ring connecting key comprises a corrugated steel web (1), a connecting accessory (2), concrete (3) and a connecting main part (4), wherein the concrete (3) is connected with the connecting main part (4), the connecting main part (4) is welded to the connecting accessory (2), and the connecting accessory (2) is welded to the corrugated steel web (1). An elastic rubber ring (5) wraps the connecting main part (4). According to the elastic rubber ring connecting key, the elastic rubber ring is arranged on the connecting portion of the connecting key, and therefore the connecting key and the concrete can change together and shrinkage stress redistribution of the concrete is reduced. In addition, the elastic rubber ring improves the stretch performance of the connecting key, and therefore the connecting key can adapt to shrinkage and creep of the concrete in the composite structure, shrinkage cracks of the concrete are avoided, and the anti-fatigue performance of the composite structure is improved.

Summary of the invention
The utility model certainly exists shrinkage and creep for the concrete in combining structure in prior art, but connecting key can not strain in the shrinkage and creep process of concrete, cause the shortcomings such as stresses re-distribution or distress in concrete, provide a kind of by flexible rubber ring being set at connecting key connecting portion, can make connecting key and concrete collaborative variation, having reduced 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 flexible rubber ring combining structure connecting key of the anti-fatigue performance of combining structure.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
Flexible rubber ring combining structure connecting key, comprise Wavelike steel webplate, coupling, concrete, connection main part, concrete be connected main part and connect, connect main part and coupling welding, coupling and Wavelike steel webplate welding, connect on main part and be enclosed with flexible rubber ring, Wavelike steel webplate surface roughness is 50-500 μ m.
As preferably, described connection main part is peg, and flexible rubber ring is wrapped in the welding position of peg and coupling.
As preferably, described connection main part is open pore steel plate, and flexible rubber ring is socketed in the hole of open pore steel plate.
As preferably, described flexible rubber ring is the macromolecular compound of vinyl, silica type or polyamine esters.
As preferably, described elastic gum snare is grown up in 5 millimeters, and cover thickness is greater than 0.5 millimeter.Peg head of a nail place is end and middle part, and energy cooperative transformation, therefore as long as the flexible space of root.
As preferably, described coupling is frange plate.
As preferably, described frange plate is the unrestrained limit formula frange plate with unrestrained limit, and formula frange plate both sides of the edge along its length in unrestrained limit are waveform.
As preferably, described open pore steel plate is eversion type open pore steel plate, and eversion type open pore steel plate comprises the otic placode that turns up, and the otic placode that turns up is to turn up and form after partly being cut by steel plate, leaves the remaining hole that otic placode is routed up rear formation on steel plate, and the otic placode that turns up is cast in concrete.
The utility model is owing to having adopted above technical scheme, there is significant technique effect: the utility model is by arranging flexible rubber ring at connecting key connecting portion, can make connecting key and concrete collaborative variation, having reduced 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 specific embodiment
Below in conjunction with accompanying drawing 1 to Fig. 3 and embodiment, the utility model 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, and Wavelike steel webplate surface roughness is 50-500 μ m.Wavelike steel webplate surface roughness is respectively 50 μ m, 80 μ m, 120 μ m, 160 μ m, 210 μ m, 310 μ m, 380 μ m, 420 μ m, different roughness, different bonding strengths can be provided, and roughness is larger, and Wavelike steel webplate 1 is stronger with the adhesion of concrete or coating.
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 flexible rubber ring being set in peg 41 and coupling 2 welding positions, can make connecting key and concrete collaborative variation, having reduced 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.
