Description
Technical Field

Background
At present, most of the commonly used structural forms in various industrial plants, warehouses and large-space public buildings are traditional roof trusses. However, the traditional roof truss is very heavy in dead weight, increases the construction measure cost of transportation, hoisting and the like, greatly increases the foundation cost of the structure, has poor corrosion resistance, and has no integrated design with the structure due to the functions of roof waterproofing and the like.
The aluminum alloy material has the characteristics of light weight, high strength-quality ratio, good corrosion resistance, basically no maintenance, easy extrusion molding, high material recycling rate, green construction and the like, so that the aluminum alloy material is widely applied to structural engineering. In view of the characteristics of the aluminum alloy materials, the defect problem of the traditional roof truss is exactly solved, and the assembly rate of the building engineering is improved.
With the deep research of aluminum alloy materials, the appearance of novel hard aluminum, super hard aluminum and other materials, and the maturity of a novel welding process-friction stir welding technology specially researched for the aluminum alloy materials, the feasibility of the implementation of the wide goose plate with the aluminum alloy structure is technically ensured.

the cross section of the wild goose plate with the aluminum alloy structure is in a wild goose shape, the included angle between the two symmetrical inclined wing plates and the horizontal direction is 20 degrees (plus 0-10 degrees), the thickness of the two symmetrical inclined wing plates is gradually thinned from the root part to the tail part, the root part is 100mm, the tail part of the inclined wing plates is reduced to 50mm, the height of the lower beam is 325mm, and the width of the lower beam is 200mm;
the thickness of the rib plate with the honeycomb aluminum alloy section and the upper and lower flange plates except the junction are that
4.0-5.0 mm, and the rest is 2.0-3.0 mm; the transverse width of the wide goose plate with the aluminum alloy structure is generally 3-4 meters, and the longitudinal span of the wide goose plate can be spanned by 9-30 meters.
The variable cross-section treatment mode not only meets the requirements of the structure on strength, deformation and stability, but also can save materials and improve economic benefits.
The symmetrical inclined wing plates are formed by combining 3 honeycomb aluminum alloy sections with variable cross sections, the lower beam is a honeycomb aluminum alloy section formed by integral extrusion, and the top horizontal wing tail connecting plate is also a honeycomb aluminum alloy section formed by integral extrusion;
the top horizontal wing tail connecting plate needs to be extruded into a folded plate, so that smooth realization of friction stir welding is guaranteed.

The top horizontal wing tail connecting plate is symmetrical in shape except at the joint; the cross section form of the junction of the top horizontal wing tail connecting plates is complementary and is a mutually fastened form, so that the aim of ensuring the reliability of connection between two wild goose plates is fulfilled, and meanwhile, the problem of water resistance of the wild goose plate roof is solved.
The assembly of the wild goose plate structure can not influence the construction progress of the working procedures such as equipment installation below the roof of the building main body. The parts constituting the wild goose plate are connected by friction stir welding. The horizontal wing tail connecting plate at the top is symmetrical in shape except at the junction; the cross sections of the junctions are fastened with each other, so that reliable connection between two wild goose plates can be ensured, and the problem of water resistance of the wild goose plate roof can be solved.

Detailed Description
The invention is further described below with reference to the drawings and examples, which are not intended to be limiting in any way.
As shown in figures 1-10, the novel aluminum alloy structure wild goose plate comprises two symmetrical inclined wing plates at the upper part, a lower beam 6 and a horizontal wing tail connecting plate at the top, wherein each part is a honeycomb aluminum alloy section. The upper two symmetrical inclined wing plates are divided into a root 5, a middle part 4, a tail 3, a lower beam 6, a horizontal wing tail connecting plate 1 and a horizontal wing tail connecting plate 2 at the top. These parts are all aluminum alloy honeycomb sections extruded at one time in the factory. Extrusion processes require the use of extrusion front equipment, extruders, extrusion back equipment, extrusion tooling including basic tools and dies, with the dies being the most important extrusion tools. Anodic oxidation and coloring are also needed to be carried out on the component after extrusion molding so as to achieve the optimal corrosion resistance and durability of the aluminum alloy.
After the members are extruded, the members are fixed by a supporting device according to the external dimensions and angles shown in fig. 1, and friction stir welding is performed at the contact positions of the members. The friction stir welding is to utilize the stirring head with special shape of hard stirring finger stick to insert the welded head and to generate heat with the welded metal in a friction stir, and simultaneously combine the extrusion of the stirring head to the weld joint metal to make the joint metal in a plastic state, and the stirring finger stick moves forward along the welding direction while rotating to form compact intermetallic combination under the combined action of heat and machine to realize the connection of materials. The stirring head consists of a stirring finger rod with a special shape and a shaft shoulder. The length of the stirring finger rod is equal to the plate thickness, but in general, the length of the stirring finger rod is slightly shorter than the thickness of the base material; and the diameter of the shaft shoulder is larger than that of the stirring finger rod. The friction stir welding does not need a filler wire and inert gas protection in the welding process; the groove and special treatment on the surface of the material are not needed before welding, and the defects of air holes, cracks and the like are not generated during welding. The materials such as hard aluminum, super hard aluminum and the like with strong heat sensitivity can be reliably connected by friction stir welding, so that the joint strength of the aluminum alloy structure is improved, and the problem of reduced joint strength of the aluminum alloy material caused by fusion welding is solved.
After all the components are connected into an integral wild goose plate through friction stir welding, the wild goose plate is transported to a factory for hoisting. Because the design considers that the horizontal wing tail connecting plates at the top are mutually fastened and considers the dimensional relationship between the horizontal direction and the vertical direction, when the wild goose plates are hoisted, only one wild goose plate is hoisted in place, and the other wild goose plate moves horizontally to the in-place wild goose plate and then moves vertically upwards, so that the lap joint of the two wild goose plates can be completed. The lapped wild goose plate roof not only realizes structural connection, but also solves the waterproof problem of the roof.
Therefore, the novel aluminum alloy structure wild goose plate with light weight, high strength, corrosion resistance, no maintenance and strong durability is formed.
The above is only a specific application example of the present invention, and other embodiments of the present invention are also possible, and all the technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by the present invention.
