A method includes forming a cutout in a bamboo pole, the cutout having a non-uniform perimeter, and in which the perimeter increases towards a region of the bamboo pole where fibers of the pole are stronger than other regions of the bamboo pole.

Various implementations include methods and apparatuses for constructing a concrete structure. In one implementation, a structure includes a pre-cast concrete column section and a pre-cast concrete beam section. The column section includes an embedded first assembly with a threaded rod, and the beam section includes an embedded second assembly defining a channel for receiving the threaded rod. Grout is fed through a joint between the column and beam sections into the second assembly to couple the threaded rod with the second assembly. The grout is urged through the joint and the second assembly by gravity and by applying vacuum suction to a grout port defined by the second assembly. The grout port extends between the channel of the second assembly and an external face of the beam section.

An apparatus for aligning and joining construction elements comprising threaded studs or bars protruding from opposing elements; interlocking members adapted to screw together associated with each of the opposed studs; an adjustment nut screwable on one of the studs wherein, the adjustment nut is screw jacked against one of the interlocking members to align the elements and then locked and encapsulated by screwing together the interlocking members. There can be additional stud or bar alignment means associated with the apparatus.

Provided is a frame structure which allow PC members to be assembled in an efficient manner. First blind holes 26 are formed in a first PC beam 11 so as to open out at longitudinal end surfaces thereof, and first through holes 31 are formed in a pair of PC columns 10 so as to open out opposite to the respective first blind holes 26. The first PC beam 11 is rigidly connected to each PC column 10 via a first rebar 32 positioned in each first through hole 31 and inserted in the corresponding first blind hole 26 to be connected to the corresponding first main beam rebar 24 via a first overlap joint 33, and grout filled around the first rebar 32 in the first through hole 31.
