The invention discloses an angle steel-gusset plate connection node semi-rigidity detection method in a power transmission angle steel tower structure. The method comprises the following steps that: S10, angle steel is installed on a gusset plate to obtain multiple groups of measuring pieces, wherein the measuring pieces are numbered, the angle steel and the gusset plate are made of Q420 steel, and bolts are 8.8-level or 10.9-level high-strength bolts of M20; S20, the measuring pieces are mounted on the testing device, and a measuring scheme is made; S30, the pressurization test is conducted on the test piece through a test device to obtain corner data of an angle steel shearing domain and a node domain; S40, the tensile test on each angle steel is carried out to obtain ultimate tensile stress, elastic modulus, yield stress and yield strain, wherein test piece sampling position of the angle steel is at a position which is 1/3 away from the limb width in the longitudinal direction of the angle steel; S50, the bearing capacity of the node plate, the local shearing corner of the angle steel and the bending moment bearing capacity of the node are is detected; and S60, the test structure of the angle steel-gusset plate is analyzed. The method has the advantage of accurate measurement data.

The invention relates to an aluminium-plastic co-extrusion profile externally buckled aluminum plate structure. The structure comprises an aluminium-plastic co-extrusion profile, the outer side of thealuminium-plastic co-extrusion profile is wrapped by an aluminous gusset plate which is in a semi-enveloping shape, the aluminous gusset plate comprises a first hook plate, a first oblique plate, a first vertical plate, a first transverse plate and a second hook plate which are integrally connected, multiple supporting points are arranged on the side, facing the aluminium-plastic co-extrusion profile, of the inner side of the aluminous gusset plate, and the aluminous gusset plate abuts against and is buckled to the outer side of the aluminium-plastic co-extrusion profile; the whole aluminium-plastic co-extrusion profile is shaped like L and is formed by an internal nylon aluminum lining composite profile and a plastic profile wrapping the exterior through co-extrusion. Accordingly, the surface physical property of the aluminium-plastic co-extrusion profile can be significantly improved, the strength weather resistant and aesthetic degree of exterior facing of the profile can be improved, the structure can be widely applied to building doors and windows of green construction standards, and standard requirements are met.
