Description

Truss type cavity plate structure and bridge deck structure Technical Field The application relates to the field of cavity plate structures, in particular to a truss type cavity plate and application thereof. Background The cavity plate is a structure formed by double-layer or multi-layer panels and connecting pieces in interlayers between the panels, and the cavity plate structure has the advantages of light weight, simple structure, excellent mechanical property, modularization construction and the like. Meanwhile, filling materials such as concrete and the like can be filled in the interlayer to form a combined structure, and a double-steel-plate-concrete combined structure is commonly used. The double steel plate-concrete combined structure consists of steel plates at two sides, sandwich concrete and a shear connector, has the advantages of a concrete structure and a steel structure, and is widely applied to structures such as nuclear power reactor shells, bridge engineering, super high-rise building shear walls and the like. The connecting piece of the traditional cavity plate is mainly used for connecting and restraining the panels on two sides, and in some bearing occasions, such as building carrier plates, bridge decks and the like, fillers such as concrete and the like are added into the cavity plate to form a combined structure, and the bearing of the concrete is realized. The self weight of the cavity plate combined structure is too large to be suitable for some light and high-strength application scenes due to the fact that the cavity plate combined structure is filled with concrete. The light high-strength cavity plate structure is formed, the connecting piece is the most critical and most sensitive node of the cavity plate at the connecting part of the connecting piece and the panels at the two sides, and the most workload part in the manufacturing of the cavity plate is also formed. The existing cavity plate connecting piece generally selects bolts, channel steel and the like, the connecting piece is difficult to achieve rigidity matching with steel plates on the outer side due to the structural limitation of the connecting piece, solid rod pieces such as bolts and the like are high in rigidity, the bolts with larger diameters are adopted, the rigidity is far larger than that of outer steel plates, and the outer steel plates can crack, so that a large number of slender bolts with small diameters are often adopted in practical application, the slender rod-shaped piece is easy to integrally flex due to insufficient rigidity, the number of connecting pieces is large, a large number of welding works are brought to a plurality of connecting pieces, the welding quality of connecting parts is difficult to guarantee due to low assembly and industrialization degree of the existing connecting pieces, and the service life of the cavity plate is directly influenced due to the various problems such as large welding residual stress. Therefore, the design of the connecting piece and how the connecting piece is connected with the two side panels are key to the construction of the high-performance cavity plate and the combined structure thereof. Disclosure of Invention The application aims to solve the problems of low manufacturing and assembly degree, high workload, large self weight and the like caused by the fact that filling materials are required to be poured due to poor pressure-bearing and shearing-resistant performances of the traditional cavity plate, and provides a truss type cavity plate. And a bridge deck structure adopting the truss type cavity plate is also provided. In order to achieve the above object, the present application adopts the following technical scheme: The truss type cavity plate structure comprises a top plate, a bottom plate, a plurality of conjuncted web members and a plurality of support web members, wherein an interlayer is arranged between the top plate and the bottom plate, the conjuncted web members are corrugated and provided with wave crest portions, wave trough portions and inclined web members positioned between the adjacent wave crest portions and the wave trough portions, reserved holes are formed in the wave crest portions and the wave trough portions, the support web members are columnar, at least one end of each support web member penetrates through the reserved holes to press and fix the wave crest portions and the wave trough portions of the conjuncted web members with the top plate or the bottom plate, and two ends of each support web member are fixedly connected with the top plate and the bottom plate respectively. Preferably, the supporting web member is fixedly connected with the top plate and the bottom plate through friction welding. The friction welding both ends synchronous welding that support web member and top bottom plate form high-efficient joint to adopt friction welding to connect, thereby not only accomplish synchronous welding with panel and bott
