Detailed Description
In order to deepen the understanding of the present invention, the following detailed description is given with reference to the accompanying drawings, which are only used for explaining the present invention and do not constitute a limitation to the protection scope of the present invention.
As shown in fig. 1-3, an unbonded prestressed large-span aluminum alloy deck comprises a deck, wherein the deck comprises an upper flat plate 1 and a lower flat plate 2, the upper flat plate 1 and the lower flat plate 2 are connected through a left connecting vertical plate 3 and a right connecting vertical plate 4, the upper flat plate 1, the lower flat plate 2, the left connecting vertical plate 3 and the right connecting vertical plate 4 form any shape with supporting force, any shape is trapezoidal or square, and the upper flat plate 1, the lower flat plate 2, the left connecting vertical plate 3 and the right connecting vertical plate 4 of the deck are integrally extruded and formed by aluminum alloy;
the left pipeline 5 and the right pipeline 6 for placing pipelines are arranged in two corners of the connecting part between the lower flat plate 2 and the left connecting vertical plate 3 and the right connecting vertical plate 4, the through holes of the left pipeline 5 and the right pipeline 6 are in any form that the prestressed tendons 150 pass through, any form is circular or polygonal, the prestressed tendons 150 are arranged in the left pipeline 5 and the right pipeline 6, the prestressed tendons 150 are steel bars, any one of steel strands or steel anchor rods, the prestressed tendons 150 are externally provided with anchors matched with the shape of the pipelines, the anchors comprise anchor backing plates 180 which are positioned on the peripheries of the prestressed tendons at the tops of the left pipeline 5 and the right pipeline 6, bear anchor rope stress and transmit the stress to an aluminum alloy deck structure, anchor rings 170 are arranged between the anchor backing plates 180 and the prestressed tendons 150, bear outward expansion force applied to the anchor clamps to play roles of energy absorption and fastening, and anchor clamps 160 are plugged between the anchor rings 170 and the prestressed tendons 150.
The anchoring of the prestressed anchor cable is based on the principle of taper hole wedging, i.e. the steel strand is anchored at the taper hole of the anchor ring by a wedge-shaped clamping piece. Firstly, tensioning the steel strand by using an anchor cable tensioning device, and slowly unloading after the designed stress value is reached. The clamping piece of the anchorage device is brought into the conical hole of the anchor ring by the steel strand bundle which retracts at a constant speed to form an anchoring unit, and the stress of the steel strand bundle is transmitted to a structure through the anchor ring and the anchor backing plate to form permanent prestress.
After the deck is extruded and formed, the prestressed tendons are placed into the unbonded prestressed tendon pipelines, the unbonded prestressed tendons are stretched by the jack, and the stretched unbonded prestressed tendons are fixed at the end parts of the deck by the anchorage device. The prestressed reinforcement tensioned by the jack generates compressive stress inside, and the pressure is transmitted to the structure of the aluminum alloy deck through the anchorage device, so that bending moment and bottom tensile stress of the deck generated by gravity and deck load are resisted. The strength and the bending deformation resistance of the aluminum alloy deck are improved.
