The utility model relates to the technical field of aluminum alloy sections, in particular to a high-strength aluminum alloy section for a combined energy-saving curtain wall, which comprises a stand column, a plurality of rib columns distributed at equal intervals are arranged on the inner side of the stand column, and ribs are arranged on the periphery of each rib column. The cross beams are located on the front side and the rear side of the stand column, fixing cylinders are arranged on the inner sides of the cross beams, and reinforcing fins are fixedly connected between the peripheries of the outer surfaces of the fixing cylinders and the inner walls of the cross beams. Under the action of the rib columns, the ribs and the honeycomb fiber braid layer, the aluminum alloy profile has the advantages of high strength and large bearing load, and the problem that the aluminum alloy profile for the combined energy-saving curtain wall possibly has insufficient strength in certain specific application scenes is solved; in particular, in a large-span, high-wind-pressure or complex-modeling curtain wall system, most traditional aluminum alloy sections are designed into single cavities, and deformation is prone to occurring when large loads are borne.

The utility model relates to the technical field of wainscots, and discloses a wainscot for indoor decoration, which comprises an anti-corrosion layer, a waterproof layer, a reinforcing layer, a wormwood fiber layer, a shock absorption layer, a sound absorption layer, an isolation layer and an anti-collision layer, the waterproof layer is fixedly connected to the upper surface of the anti-corrosion layer, and the reinforcing layer is fixedly connected to the upper surface of the waterproof layer. The anti-corrosion layer is formed by laying the bamboo wood fiber boards, the bamboo wood fiber boards are light in material, not prone to deformation and aging and good in anti-corrosion effect, the service life of the attached position of the wall protection board and a wall can be guaranteed, the waterproof layer is formed by laying the plastic film, water can be prevented from permeating into the wall protection board, and the service life of the wall protection board is prolonged. The reinforcing layer is formed by laying PVC boards, the internal strength of the wall protection board can be improved, the wormwood fiber layer is formed by pressing wormwood fibers and has certain flexibility and elasticity, and when the wormwood fibers are impacted by external force, the wormwood fibers can absorb and disperse impact energy through deformation of the wormwood fibers.

The application discloses a stress luminescence type chemical anchoring fog seal layer material with blackening and wear resistance functions and a construction method thereof, and relates to the technical field of pavement engineering pre-maintenance. The fog seal layer material is prepared from near-neutral non-ionic emulsified asphalt as a stable reaction matrix, high-carbon black content activated latex slurry is introduced to realize blackening and network enhancement of the asphalt pavement, the interface bonding and mechanical-optical response triggered by traffic load are realized through core-shell structure stress luminescence particles, and the interface chemical anchoring reaction is triggered when the demulsification of the interface catalytic anti-skid aggregate. The components play a synergistic effect in the storage, construction and service stages, and finally form a reinforced seal layer with stress luminescence visual guidance, high blackness, high anti-skid and long-term durability functions on the pavement, and the application is especially suitable for improving the road traffic safety in dark environments such as tunnels and road sections without street lamps.
