All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
There is shown in the drawings a schematic block diagram of a disclosed embodiment in accordance with the invention. The figures are not drawn to scale, wherein certain details are exaggerated and possibly omitted for clarity of presentation. The shapes of various regions, layers and their relative sizes and positional relationships shown in the drawings are merely exemplary, and deviations may occur in practice due to manufacturing tolerances or technical limitations, and a person skilled in the art may additionally design regions/layers having different shapes, sizes, relative positions, according to actual needs.
Referring to fig. 1 to 4, the shear wall with the lightweight sandwich anti-buckling steel plate embedded with the obliquely arranged FRP section corrugated plates comprises a shear wall body, FRP section corrugated plates 1 are arranged on two sides of an embedded steel plate 3 in the shear wall body, PET structural foam 2 is filled between the FRP section corrugated plates 1 and the embedded steel plate 3, and the FRP section corrugated plates 1 are distributed obliquely.
The FRP profile corrugated plate 1 is connected with the embedded steel plate 3 through an interface binder and a high-strength bolt 4 with a circular gasket to form a combined wall body, and the inclination angle of the FRP profile corrugated plate 1 is 45 degrees. And the axes of the FRP section corrugated plates 1 at the two sides of the embedded steel plate 3 are vertical to each other.
The PET structural foam 2 of the present invention is used as a filler material, and other lightweight filler materials may be used instead.
The cross section of the PET structural foam 2 is trapezoidal and is consistent with the wave trough shape of one side of the FRP section corrugated plate 1 facing the embedded wallboard.
The embedded steel plate 3 is connected with the steel beam 8 and the steel column 7 in the shear wall body through welding or through a fishplate 6 and a bolt 5.
The construction process of the invention is as follows: adhering PET structural foam 2 and FRP section corrugated plates 1 on an embedded steel plate 3 through an interface adhesive, and mounting a high-strength bolt 4 with a circular gasket after punching to form a combined wall; and finally, connecting the combined wallboard, the steel column 7 and the steel beam 8 by welding or using a fishplate 6 and a bolt 5 to complete the construction of the wall body.
The invention has the following characteristics:
1) according to the invention, the combined section formed by the FRP section corrugated plates 1 on the two sides of the embedded steel plate 3 and the PET structural foam 2 can obviously improve the out-of-plane bending rigidity of the embedded steel plate 3, and effectively limit the out-of-plane shearing buckling deformation of the embedded steel plate 3, thereby improving the side rigidity resistance of the whole structure.
2) According to the invention, the arrangement of the wave trough and wave crest widths of the FRP section corrugated plate 1 controls the plane external rigidity distribution of the FRP section corrugated plate 1, so that the local buckling deformation of the wallboard is concentrated at the wave trough position of the PET structural foam 2, and further, the energy absorption and noise elimination effects are achieved through the elastic deformation of the PET structural foam 2.
