A length-adjustable bamboo pole extension structure

Abstract

The invention discloses a bamboo rod lengthening structure with adjustable size, which comprises an upper structure and a lower structure, wherein the upper structure comprises a first central fixingblock and a plurality of first limiting plates; the lower structure comprises a second center fixing block and a plurality of second limiting plates; a plurality of first screw rods are fixed on the first central fixing block in the circumferential direction, a first supporting plate is arranged between two adjacent first screw rods, wherein the end part of each first supporting plate is connectedwith the first central fixing block, and one first limiting plate corresponds to one first screw rod, and the side face of the lower end of each first limiting plate sleeves on a corresponding firstscrew rod, and each first limiting plate is distributed in the circumferential direction, and each first screw rod sleeves with a first nut, and the first nut is positioned on the outer side of the first limiting plate on the first screw rod, so that the structure can realize firm connection between two raw bamboo with any diameter and has good universality.

Description

Technical field [0001] The invention belongs to the field of bamboo structures, and relates to an adjustable bamboo pole extension structure. Background technique [0002] Under the global trend of energy conservation and environmental protection, bamboo has been widely used in building structures due to its easy reproduction, fast growth, early maturity and high yield, and has been widely used in building structures, especially in some earthquake-prone areas or tourist attractions. At the same time, it is usually necessary to extend the bamboo poles. The existing method of extension basically adopts the binding method, and the fixing method is relatively primitive. In addition, the disclosed technology also involves clamping two raw bamboos between multiple fixing plates. However, this method of clamping and fixing is relatively firm for raw bamboos of the same diameter, but loosely for raw bamboos of different diameters, and has poor versatility and cannot achieve standardizati...

Problems solved by technology

[0002] Under the general trend of global energy saving and environmental protection, bamboo has been widely used in building structures due to its characteristics of easy reproduction, fast growth, early maturity and high output, especially in some earthquake-prone areas or tourist areas. Usually, it is necessary to lengthen the bamboo poles. The existing way of lengthening basically adopts the method of binding, and the fixing method is relatively primitive. In addition, the disclosed technology also involves clamping two original bamboos between multiple fixing plates. However, this clamping and fixing method is relatively firm for the original bamboo with the same diameter, but it is relatively loose for the original bamboo with different diameters. At the same time, the versatility is poor, and the standardization of the connecting parts cannot be realized.
