Untwining cold pressing column capable of infinitely extending

Abstract

The invention provides an untwining cold pressing column capable of infinitely extending. The cold pressing column is a square column and comprises a plurality of sequentially connected column parts and a fixed connecting part, wherein the end parts of the connected column parts are connected in a way that bulges are embedded in grooves; each column part is formed by pressing a plurality of bonded column sheets; a plurality of layers of main parts are pressed to form the square column after being bonded; the column sheets are bamboo untwining sheets; the adjacent untwining sheets are bonded in a staggered way; bulges and grooves are respectively formed in the end parts of the adjacent untwining sheets; the bulges are connected into the corresponding grooves through glue; the fixed connecting part comprises a rivet and outer fixed blocks; the bulges and the grooves of the column parts are respectively bonded together with the grooves and the bulges of the adjacent column parts; and then, the rivet sequentially passes through the bulges and the grooves so that the column parts are connected. Fixed grooves formed by two ends of the rivet and the column sheets are bonded with the outer fixed blocks; and the outer fixed blocks are fixed outside the rivet and can be used for keeping the surface of an upright column smooth while reinforcing connection, so that the condition that the impression of the upright column is influenced by the exposure of the rivet is avoided.

Description

technical field [0001] The invention relates to a decomposing infinitely extended cold-pressed column. Background technique [0002] In the production of furniture and bamboo pavilions in scenic spots, it is often necessary to connect solid wooden or bamboo columns so that the length meets the production requirements. In the current processing process, the connection is usually realized by using bolts, rivets and other connecting parts, but the existing connection affects the appearance of the column after the column is made due to the exposed connecting parts, and the exposed connecting parts are easily affected by the outside world and loosen, making The connecting position is easy to be misaligned, which increases the probability of maintenance and affects the service life of the column. Contents of the invention [0003] The purpose of the present invention is to provide a debonded infinitely extended cold-pressed column, which can use a simple structure to re...
