Description

Technical Field

[0001] The present application relates to the field of civil engineering technology, and in particular to a steel-wood composite assembled shear wall component and a steel-wood composite shear wall. Background Art

[0002] Wood is a green and environmentally friendly renewable material. Dimensional lumber and glulam products have been widely used in various large-scale construction projects and are highly assemblable. However, wood has problems such as easy deformation and large strength differences along the horizontal direction. Steel is a modern material that is light and strong, but has poor fire resistance and thermal insulation. The steel-wood composite structure can combine the advantages of steel and wood and make them work together. Steel can improve the rigidity of wood, while wood can prevent local buckling of steel and enhance the integrity of the structure. In addition, the steel-wood composite structure performs well in thermal insulation.

[0003] At present, steel-wood composite components mainly include steel-wood composite wall panels, steel-wood composite floor panels, steel-wood composite beams and steel-wood composite columns. Existing studies have shown that compared with steel structures and wood structures, steel-wood composite structures have better bearing capacity, ductility and seismic performance. At present, most of the research on steel-wood composite structures focuses on steel-wood composite beams and steel-wood composite columns. There are relatively few studies on steel-wood composite wall panels, and their forms mainly include composite wall panels and reinforced wall panels, such as light steel keels covered with wooden boards, steel frames filled with wooden shear walls, thin steel webs and wooden boundary frame shear walls, etc. However, these steel-wood composite shear walls are generally suitable for multi-story buildings or some temporary buildings, and are not suitable for high-rise buildings. Therefore, it is very meaningful and has a promising application prospect to design a steel-wood composite shear wall suitable for high-rise buildings with a high degree of assembly, convenient on-site construction and good seismic performance.

[0005] According to a first aspect of an embodiment of the present application, there is provided a steel-wood composite assembled shear wall component, comprising a web, an end column, a floor hidden beam, a vertical stiffening rib, and orthogonal glued laminated timber;

[0006] The vertical stiffening ribs, end columns, and floor hidden beams are all welded to the web to form a main steel frame; wherein the web and its left and right end column flanges and upper and lower hidden beam flanges enclose an open cavity; orthogonal glued timber is embedded in the open cavity, the orthogonal glued timber and the main steel frame are bonded with glue, and the orthogonal glued timber and the web, end columns, and floor hidden beams are fixedly connected with bolts respectively, so that the orthogonal glued timber and the main steel frame are reliably connected.

[0007] Furthermore, the cross-laminated timber and the main steel frame are bonded by epoxy resin structural adhesive.

[0008] Furthermore, the web, vertical stiffening ribs, end columns and floor hidden beams are welded to form a main steel skeleton.

[0009] Furthermore, the floor hidden beam is an I-beam or is formed by vertically welding two horizontally parallel steel plates with a certain distance between them on the web.

[0010] Furthermore, the end column is an I-beam or is formed by vertically welding two steel plates which are parallel in the vertical direction and spaced a certain distance apart on the web.

[0011] Furthermore, the cross-laminated timber is obtained by gluing together standard timber with alternating horizontal and vertical grains.

[0012] Furthermore, reserved bolt installation holes for steel are arranged on the webs, end columns and floor hidden beams, and reserved bolt installation holes for cross-laminated timber are arranged on the cross-laminated timber, and through bolts pass through the reserved bolt installation holes for steel and the reserved bolt installation holes for cross-laminated timber to realize the connection between the cross-laminated timber and the webs, end columns and floor hidden beams.

[0013] Furthermore, the through bolts are double-headed threaded bolts with gaskets at both ends, and are perpendicular to the web, end column, floor hidden beam and orthogonal glued timber.

[0014] Furthermore, the positions and number of the reserved bolt installation holes of the orthogonal glued laminated timber correspond to the reserved bolt installation holes of the steel plates of the webs, end columns and floor concealed beams.

[0015] According to a second aspect of an embodiment of the present application, a steel-wood composite shear wall is provided, which is obtained by assembling the components described in the first aspect.

[0016] The technical solution provided by the embodiments of the present application may have the following beneficial effects:

[0017] It can be seen from the above embodiments that, compared with the existing steel plate shear wall, the steel-wood composite assembled shear wall component of the present application has orthogonal glued laminated timber wrapped on the outside of the main steel frame, which enhances the local stability of the main steel frame, is conducive to the full strength of the steel, and can play a role in energy saving and heat preservation, reducing the carbon emission of the building structure; compared with the existing wood structure, the main steel frame is set, and the axial force, bending moment and shear force are jointly borne by steel and wood, and the ultimate bearing capacity and lateral stiffness of the wall are significantly improved; compared with the existing steel-concrete composite shear wall, wood is a renewable material, green and environmentally friendly, carbon emissions and dust pollution are effectively reduced, and the on-site construction and installation are convenient, and the degree of assembly is high. Therefore, the steel-wood composite assembled shear wall component of the present application is a steel-wood composite component with high bearing capacity, heat preservation and energy saving, green and environmental protection, and convenient construction, which provides a new idea for the development of assembled steel-wood composite structures and can better promote the promotion and application of steel-wood structures.

[0029] As attached Figures 1 to 5 As shown, an embodiment of the present application provides a steel-wood combined assembled shear wall component, including a web 1, an end column 2, a floor hidden beam 3, a vertical stiffening rib 5, and an orthogonal glued timber 6; the vertical stiffening rib 5, the end column 2, and the floor hidden beam 3 are all welded to the web 1 to form a main steel frame; wherein the web 1 and the flanges of its left and right end columns 2 and the flanges of the upper and lower floor hidden beams 3 are enclosed to form an open cavity; the orthogonal glued timber 6 is embedded in the open cavity, the orthogonal glued timber 6 and the main steel frame are bonded with glue, and the orthogonal glued timber 6 and the web 1, the end column 2, and the floor hidden beam 3 are respectively fixedly connected with bolts, so that the orthogonal glued timber 6 and the main steel frame are reliably connected.

[0030] Among them, the web 1, the end column 2, the floor hidden beam 3 and the vertical stiffening rib 5 are all made of steel; the end column 2 can be an I-beam or formed by two steel plates that are parallel in the vertical direction and spaced a certain distance apart and vertically welded to the web, and the floor hidden beam 3 can be an I-beam or formed by two steel plates that are parallel in the horizontal direction and spaced a certain distance apart and vertically welded to the web.

[0031] Specifically, the junctions of the web 1, the end column 2, the floor hidden beam 3 and the vertical stiffening rib 5 are fixed by corner welds. After the end column 2 and the floor hidden beam 3 are welded to the web 1 to form a whole, the overall stiffness, bearing capacity and ductility of the component are greatly improved.

The epoxy resin structural adhesive 7 is also coated in the open cavity of the main steel frame, and then the orthogonal glued timber 6 is embedded in the open cavity. The orthogonal glued timber 6 on both sides is then clamped with a clamp. After the epoxy resin structural adhesive 7 is cured, the orthogonal glued timber 6 is further fixed with through bolts 4 that pass through the reserved bolt mounting holes 8 of the steel plate and the reserved bolt mounting holes 9 of the orthogonal glued timber, ensuring that the orthogonal glued timber 6 and the main steel frame work together to bear force and improve the integrity and bearing capacity of the component.

[0037] The through bolt 4 can be a double-headed threaded bolt with washers at both ends, and is perpendicular to the web 1, the end column 2, the floor hidden beam 3 and the cross-laminated timber 6. The hole diameter of the steel plate reserved bolt installation hole 8 and the cross-laminated timber reserved bolt installation hole 9 is about 1.5 mm larger than the diameter of the through bolt 4, which is convenient for the installation of the through bolt 4.
