Description
Technical Field
The utility model relates to a glass fiber pultrusion product preparation field especially relates to novel heat preservation wear-resisting glass fiber reinforcing pultrusion's cavity bridge panel.
Background
The deck slab, also known as a roadway slab, is a load-bearing structure that directly bears the wheel pressure of the vehicle. The bridge deck is generally integrally connected with beam ribs and transverse clapboards of a main beam in terms of construction, and a concrete reinforcement structure is adopted in the design of a bridge deck in China at present. The construction is generally carried out by adopting a concrete on-site pouring mode in the construction process, and due to the characteristics of the concrete, the construction period is longer, the labor intensity is high, and meanwhile, great inconvenience is brought to traffic. After the concrete bridge deck is used for a period of time, cracks are easy to generate, and if steel is exposed, the steel is easy to corrode. The concrete bridge deck is often required to be maintained and repaired, and the general bridge deck has a complex structure and insufficient strength for bearing the gravity. And the glass fiber reinforced section bar is adopted as a bridge panel, so that the internal force of the supporting structure and the lower structure can be reduced, the environment erosion and load action can be directly resisted, and the maintenance cost is reduced.
The composite material bridge deck slab which is industrially produced at present can be divided into a sandwich plate, a pultrusion section assembled hollow plate, a panel-section core composite plate and a glass fiber reinforced-concrete/wood composite plate according to the structural form of the glass fiber reinforced section as the bridge deck slab. Most of the sandwich plates are made by adopting an RTM (resin transfer molding) process, so that the integrity is good; the pultruded profile panel is a spliced panel, has strong adaptability, is suitable for industrial production, is limited by a production process, has no overlarge section size, is mainly made of unidirectional fibers, and has poor transverse stress performance; although the composite board can obtain good stress performance through reasonable design, the production process is complex, and mass production is difficult to achieve.
The pultrusion hollow bridge panel has strong adaptability and is suitable for industrial production, but is limited by the production process, the section size cannot be overlarge, the longitudinal fibers are main, and the transverse stress performance is poor. Therefore, the cross-section structure with reasonable design is adopted, the transverse stress performance is improved, and the quality of the pultrusion hollow bridge panel can be greatly improved.
