Description

Technical Field

[0001] The utility model belongs to the technical field of aluminum and wood structure buildings, and particularly relates to an aluminum-clad wood combined column structure. Background Art

[0002] Currently, wood, steel, and concrete are commonly used for column structures in buildings and structures such as houses, factories, and bridges. However, concrete structures are increasingly characterized by high energy consumption and weight, making them unable to meet the demand for lightweight, energy-saving, and low-consumption structures. Coastal areas have a humid climate, and the high salt and humidity in the environment can easily cause steel to rust and degrade, leading to localized instability when subjected to stress. Wood has good pressure-bearing capacity and is aesthetically pleasing, but it swells and softens when exposed to water, and easily loses its bearing capacity when subjected to tension in humid environments, compromising structural safety. Applying a waterproof coating requires extensive construction and is costly. Aluminum offers aesthetic appeal, corrosion resistance, and high strength, but is relatively expensive.

[0003] Therefore, it is necessary to provide a column structure that is suitable for coastal high-salt and high-humidity environments, has strong bearing capacity, is environmentally friendly, and is easy to construct. Utility Model Content

[0004] The present invention aims to solve the technical problems raised in the above background technology, and aims to provide an aluminum-clad wood composite column structure, which gives full play to the superior mechanical properties of wood and aluminum, and maximizes the bending bearing capacity of the composite column to achieve efficient combined use of wood and aluminum. The specific implementation plan is as follows:

[0005] An aluminum-clad wood composite column structure includes a thin-walled square aluminum tube, an equilateral thin-walled L-shaped aluminum material, plywood, bolts, self-tapping screws, bolt washers, and structural adhesive; characterized in that the thin-walled square aluminum tube is surrounded and tightly attached by four plywood boards, the end faces of the plywood boards are kept flush with the surfaces of adjacent square aluminum tubes, and the inner sides are tightly attached to the thin-walled square aluminum tubes, two equilateral thin-walled L-shaped aluminum materials are provided, the two equilateral thin-walled L-shaped aluminum materials are wrapped around and tightly attached to the outside of the plywood boards, the two sides are connected to each other and closed by welding, the equilateral thin-walled L-shaped aluminum materials are provided with reserved bolt holes and self-tapping screw holes through welding, the bolts are driven in from the outside of the thin-walled square aluminum tube, pass through the equilateral thin-walled L-shaped aluminum material, the plywood, and the bolt washers, and the self-tapping screws pass through the equilateral thin-walled L-shaped aluminum material and are driven into the plywood boards.

[0006] The plywood board is composed of four rectangular boards of the same size, and the surface formed by the length and thickness directions is called the end surface.

[0007] The wooden boards and the wooden boards, as well as the wooden boards and the thin-walled square aluminum tubes are all coated with structural adhesive and maintained under pressure for 3 days.

[0008] The bolt holes are located at the midpoints of each side of the thin-walled square aluminum tube and the equilateral thin-walled L-shaped aluminum material, and are symmetrically and spacedly distributed in the length direction.

[0009] The self-tapping screw holes are on each side of the equilateral thin-walled L-shaped aluminum material, specifically located at the intersection of the midpoint of the end face of the glued wooden board and the extension perpendicular to each side, and are symmetrically and spacedly distributed in the length direction.

[0010] In summary, the present utility model has the following beneficial effects:

[0011] 1. Using aluminum material to seal and wrap the wood can avoid the problem of wood getting damp and rotting. It makes full use of the compressive and flexural resistance of dry wood and the corrosion resistance and non-rusting property of aluminum material, and is especially suitable for the coastal environment with high salt and high humidity.

[0012] 2. The hollow design is adopted in the middle of the composite column, which not only reduces the use of materials but also maximizes the utilization of the compressive capacity of wood and the corrosion resistance of aluminum alloy.

[0013] 3. By taking advantage of the strong compressive capacity of wood and the strong tensile capacity of aluminum material, the compressive, tensile and bending capacities of the aluminum-wood composite column will tend to be balanced and greatly improved.

[0014] 4. Both wood and aluminum materials are lightweight building materials. Compared with steel frames and concrete structures, their weights are greatly reduced. Large equipment is not required for handling and construction, and it is also applicable to mountainous buildings.

[0015] 5. Each component can be prefabricated and installed, and is less affected by seasonal factors, which can shorten the construction time, can be disassembled and recycled, and effectively improve the construction efficiency of buildings. BRIEF DESCRIPTION OF THE DRAWINGS
