The first connecting member 100, the second connecting member 200, and the rib structure 500 are connected in the fitting concave 401a of the formwork structure 400 by friction stir welding or friction stir spot welding. Specifically, the first connecting member 100 and the second connecting member 200 are respectively installed at openings at both ends of the fitting concave surface of the formwork structure body 400; a plurality of rib structures 500 are arranged in the assembly concave surface 401a between the first connector 100 and the second connector 200 at equal intervals, namely: the length of the long side of the first connecting piece 100, the length of the long side of the second connecting piece 200 and the length of the long side of the rib plate structural piece 500 are the same as the width of the wide side of the assembling concave surface 401a, the first connecting piece, the second connecting piece and the rib plate structural piece are integrally clamped in the assembling concave surface 401a, and the contact surfaces of the first connecting piece, the second connecting piece and the rib plate structural piece with the assembling concave surface 401a are connected into a whole through a friction stir welding or friction stir spot welding process.
Wherein: the friction stir welding is a method of utilizing a stirring head rotating at a high speed to prick into a workpiece and then move along a welding direction, generating friction heat at a contact part of the stirring head and the workpiece to enable surrounding metal to form a plastic softening layer, filling a cavity formed behind the stirring head with the softening layer metal under the rotation action of the stirring head, and realizing solid-state welding of materials under the extrusion action of a shaft shoulder of the stirring head.
The friction stir spot welding is different from the friction stir welding in that a stirring head of the friction stir spot welding does not need to move left and right after being pricked into a workpiece, the contact part of the workpiece to be connected and the stirring head generates friction heat to enable metal around the workpiece to form a plastic softening layer, and the metal in the softening layer is fully mixed together under the action of rotation of the stirring head to realize solid-state welding of materials.
The traditional building template (including aluminum alloy wall plate and floor plate) is generally formed by cutting aluminum profiles, the end plate structural bodies on two sides are formed by punching aluminum plates, and the rib plates between the two end plate structural bodies are extruded pipes made of aluminum materials and are connected and formed by an electric fusion welding method. The method of electric fusion welding has the advantages of low working procedure efficiency, high energy consumption, great pollution of photoelectricity and smoke generated in the process of electric fusion welding to the environment, and is unfavorable and environment-friendly. In addition, by adopting the electric fusion welding process, various defects such as slag inclusion, holes, incomplete penetration, large welding thermal stress and the like are easily generated at the welding seam of the template; therefore, the service life of the traditional aluminum alloy wallboard and floor slab is generally very short, and is generally only about 30 times.
The material of the template structure body 400 is 6061 aluminum alloy extruded material, the material of the first connecting piece 100, the second connecting piece 200 and the rib plate structure body 500 is liquid or semi-solid alloy, the liquid or semi-solid alloy can be processed into specifications and sizes suitable for friction stir welding or friction stir spot welding during forming, and each adjacent end surface can be vertically arranged by ninety degrees during direct processing, so that the convenience during welding is improved, the contact area of a welding part is increased, and the stability of the whole structure is improved.
It should be further noted that the aluminum metal alloy material is a common material of the existing building formwork, and has the advantages of low gravity and high strength, and the existing aluminum building formwork has defects at the joints of end connection, reinforcing of the rib plate and the like, which results in insufficient structural strength and short service life. In this embodiment, the first connecting member 100 and the second connecting member 200 of the cavity structure, which are die-cast by the liquid or semi-solid alloy, are used as end connecting members of the building template, so that the problem of insufficient strength of the existing aluminum building template can be effectively solved.
Furthermore, because the 6061 aluminum alloy extrusion material and the liquid or semi-solid alloy are two different materials, reliable connection cannot be performed through traditional welding modes such as capacitance welding and the like; therefore, the welding process of friction stir welding or friction stir spot welding is adopted in the embodiment, and the problem that reliable welding cannot be performed between two materials can be effectively solved.
Further, the friction stir welding has the following advantages: when a part of the structural body (such as the first connecting piece 100 or the second connecting piece 200 or the rib plate structural member 500) is damaged, only the damaged part needs to be removed, and then the structural body is installed in a friction stir welding mode without replacing the whole building template, so that the maintenance cost is greatly reduced.
In this embodiment, for the mode of traditional electric capacity welding, through friction stir welding or friction stir spot welding, have the energy consumption extremely low, green, welding thermal stress is little and work piece non-deformable characteristics such as, and the rigidity of whole building templates is stronger in actual operation in-process, and the economic benefits who gains thereupon is higher.
