Embodiment Construction

[0017] The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings: this embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation methods and specific operating procedures are provided, but the protection scope of the present invention is not limited to the following the described embodiment.

[0018] Such as figure 1 As shown, the embodiment of the present invention selects moso bamboo 1 with a diameter of about 6-10 cm, and dries it. The carbon fiber cloth specially used for building reinforcement is selected, the material is polyacrylonitrile carbon fiber cloth, the carbon fiber content per unit area is 200 g / ㎡, and the unidirectional tensile strength is greater than 2000 Mpa. In the middle of every two bamboo joints 2 of moso bamboo 1, a layer of carbon fiber cloth 3 with a width of 3 to 5 cm is used to surround and paste it. The carbon fiber cloth spec...

Abstract

The invention discloses a preparation method of carbon fiber-reinforced moso bamboo serving as a secondary structure of a steel structure. The method comprises the following steps of: selecting dried moso bamboo; winding a layer of carbon fiber cloth between every two bamboo joints of the moso bamboo for bonding to hoop and constrain the moso bamboo with the carbon fiber cloth; reinforcing the tips of the moso bamboo by using carbon fiber cloth by wounding two layers of carbon fiber cloth on the tips of the moso bamboo to enhance the joint strength of the moso bamboo; locally punching the tips of the reinforced moso bamboo; and connecting the moso bamboo with other moso bamboos or steel structures with bolts. In the invention, the moso bamboo is constrained by using the carbon fiber cloth, so that the compression strength and bending strength of the moso bamboo are enhanced remarkably, and the moso bamboo can be connected with other moso bamboos or other steel structures conveniently.

Description

technical field [0001] The present invention relates to a kind of manufacturing method of construction engineering material, more specifically, relate to a kind of manufacturing method of carbon fiber reinforced moso bamboo used as steel structure secondary structure. Background technique [0002] Existing moso bamboo is used as building material, generally it is used to replace steel bar and work together with concrete. Or make bamboo fiber and mix it in concrete for use. The problems with these traditional usages are the bonding problem between moso bamboo and concrete, and the insufficient compressive strength or flexural strength of moso bamboo. [0003] The tensile strength of moso bamboo is as high as 100-200Mpa, which is close to the tensile strength of steel, while the compressive strength of moso bamboo is only 30-60Mpa. Compared with the tensile strength of moso bamboo, the compressive strength of moso bamboo is much lower. The main reason is that moso bamboo is...
