[0034] Example 1

[0035] like Figures 1 to 3 As shown, this utility model provides a prefabricated bamboo-based foamed concrete insulated structural column, including a foamed concrete column 1, which serves as the main component and provides stability. Bamboo reinforcing bars 3 are distributed along the height of the foamed concrete column 1, replacing steel reinforcing bars and reducing the column's self-weight. Longitudinal steel bars 2 penetrate the bamboo reinforcing bars 3, and the bamboo reinforcing bars 3 are fixedly connected to the longitudinal steel bars 2, significantly improving the tensile strength and load-bearing capacity of the structural column. Horizontal bamboo tubes 4 are also provided inside the foamed concrete column 1, fixedly connected to the bamboo reinforcing bars 3, which not only enhances the lateral stability of the structural column but also provides space for pipeline installation. Symmetrical male grooves 6 are provided on both sides of the outer wall of the foamed concrete column 1 for installing prefabricated wall panels with corresponding female grooves, reducing construction time.

[0036] like Figures 5 to 6 As shown, the cross-section of the foamed concrete column 1 is a square with a length × width of 200 × 200 mm. The foamed concrete column 1 comprises foamed concrete and a first bamboo fiber 8; the density of the foamed concrete is 1100 kg / m³. 3 With a strength of 13 MPa and a thermal conductivity of 0.1 W / (m·K), the foamed concrete column 1 possesses the advantages of being lightweight, high-strength, and providing thermal insulation. The first bamboo fiber 8 is uniformly and non-directionally distributed within the foamed concrete, with an admixture content of 0.03% of the dry weight of the foamed concrete. The first bamboo fiber 8 has a length of 15 mm, a fineness of 10 dtex, and a strength of 2 CN / dtex. It can form an effective reinforcing network structure within the foamed concrete, reducing the weight of the foamed concrete column 1 while significantly improving the mechanical properties and crack resistance of the foamed concrete.

[0037] like Figure 4As shown, the bamboo stirrup 3 includes bamboo, which replaces steel bars, reduces the self weight of the structural column, and reduces carbon emissions. The width of the bamboo stirrup 3 is 25mm, the thickness is 8mm, and the spacing in the height direction is 150mm, forming a stable reinforcing network structure. A protective layer is arranged between the bamboo stirrup 3 and the outer wall of the foamed concrete column 1, and the thickness of the protective layer is 25mm, which improves the durability of the structural column. Two rows of slot holes 7 are arranged on both sides of the bamboo along the length direction, the horizontal spacing of the slot holes 7 is 10mm, the depth is 1mm, and the width is 2mm, and the slot holes 7 are filled with quartz sand and epoxy resin adhesive. The quartz sand has high hardness and wear resistance, which can significantly improve the wear resistance of the bamboo surface, and also increase the friction between the bamboo and the surrounding foamed concrete, and improve the overall connection strength. The epoxy resin adhesive plays a role in fixing the quartz sand and enhancing the bonding force between the quartz sand and the bamboo, and the epoxy resin adhesive has the advantages of high strength, corrosion resistance, strong adhesion and the like, which can effectively improve the overall performance of the filling material in the slot hole 7.

The bamboo fiber rope 5 includes 20 second bamboo fibers, the diameter of the bamboo fiber rope 5 is 2mm, and the pitch is 10mm. The bamboo fiber rope 5 extends in parallel along the slot hole 7 at the middle position of the slot hole 7 in the vertical direction, and when it is wound to the other row of slot holes 7, the winding angle is θ, that is, the included angle between the connecting line of the slot hole 7 and the horizontal line, θ=45°. The bamboo fiber rope 5 is wound above the slot hole 7, and the epoxy resin glue is coated on the bamboo fiber rope 5, and is cured after pressing to form a 0.5mm high protrusion. A stainless steel buckle is buckled into the end of the bamboo stirrup 3 to close, which enhances the seismic ductility of the structural column.

[0038] The number of longitudinal steel bars 2 is four, and the four longitudinal steel bars 2 are arranged in a rectangular shape in the foamed concrete column 1, and are respectively located at the four corners of the bamboo stirrup 3, which improves the carrying capacity and stability of the overall structure of the structural column.

[0039] The length of the horizontal bamboo tube 4 is the same as the width of the foamed concrete column 1, the diameter of the horizontal bamboo tube 4 is 6cm, and the number of the horizontal bamboo tube 4 is two, which are respectively located at the top end and the bottom end of the foamed concrete column 1, which not only can enhance the overall strength of the foamed concrete column 1, but also can provide convenient conditions for subsequent pipeline transportation and construction operation.

[0040] The male groove 6 is trapezoidal, the slot width of the male groove 6 is 60mm, the protruding length is 10mm, and the inclination angle is 40°, which is convenient for assembling with the corresponding female groove of the fabricated wall panel, and reduces the construction time.

[0041] Therefore, the utility model adopts the above-mentioned one kind of fabricated bamboo foamed concrete heat preservation type structural column, has the advantages of light weight, good heat preservation effect, more environmental protection, short construction period, and convenient pipeline passing.

[0042] It should be pointed out finally that the above embodiments are only used to illustrate the technical solutions of the present application but not to limit it.
