The gap between the inner wall of the reference raw bamboo and the extension raw bamboo and the outer wall of the embedded raw bamboo is not more than 2 mm.
The pin bolt is made of bamboo, wood, metal and plastic materials, is preferably made of bamboo and wood, and is provided with anchoring structures at two ends according to requirements.
The lengths of the embedded original bamboos extending into the reference original bamboos and the extension original bamboos are equal to each other and are not less than 100mm respectively.
The connection end face of the reference raw bamboo and the extension raw bamboo is perpendicular to the axis direction of the connection position.
The axial directions of more than 1 pin bolt are along the same or staggered diameter directions, and the diameter directions which are staggered with each other are preferably adopted.
The adhesive is one of epoxy resin, vinyl resin and polyurethane resin, and is applied or filled into the gap between the inner wall of the reference raw bamboo and the extension raw bamboo and the outer wall of the embedded raw bamboo.
The pin can be omitted as desired.
The invention adopts the raw bamboos with smaller diameters to realize the mutual butt joint and the length extension of a plurality of raw bamboos with larger diameters, has convenient connection, beautiful appearance and low connection cost, greatly improves the adaptability of a building structure to the requirement of the large length of the raw bamboos, and has the following advantages compared with other continuous extension structures of the raw bamboos:
(1) the central lines of the connected original bamboos are on the same straight line, so that better force transmission can be realized, and the reduction of the tensile, compressive and bending bearing capacity of the connecting structure is reduced.
(2) The original bamboos connected adjacently are integrated by the pin bolt, the adhesive and a plurality of measures of the embedded original bamboos, so that the structural integrity is guaranteed.
(3) The connection operation is simple, the manufacture is convenient, and the connection cost is low.
(4) Because the connecting end faces of the adjacent lengthened raw bamboos are tightly attached, the sizes, the shapes and the central lines of the cross sections of the connecting end faces are consistent with each other, the connecting position has no staggered platform, and the appearance is attractive.
