The connecting plate 2 is inserted into the notch formed at the end part of the laminated wood beam, and then the bolt 11 is inserted into the jack on the laminated wood beam and the bolt hole on the connecting plate. Thus, the connection between the wood beam and the wood column is realized.
As a further improvement to the above-described glued wood beam-column connection, there are two of the side connections; two ends of the screw rod respectively penetrate through screw rod jacks on the two side connecting pieces to be connected with the screw cap, and the two side connecting pieces are symmetrical. Like this, this connecting piece can realize being connected of post and two wooden beams of both sides, and the structure is simpler.
As a further improvement to the above-described laminated wood beam-column connector, the side connector further includes an auxiliary screw passing through an auxiliary screw insertion hole formed in the connecting plate. The auxiliary screw penetrates through the auxiliary screw jack and is drilled into the column to serve as further reinforcement, and the connecting piece can be prevented from loosening.
As a further improvement of the glued wood beam-column connecting piece, a positioning notch is formed in the edge of the connecting plate and is located right above the bolt hole in the vertical direction parallel to the base plate. In the installation process of the beam, because the bolt hole can not be observed in the beam, and the positioning notch is arranged at the edge of the upper part of the connecting plate, people can roughly judge the position of the bolt hole according to the position of the seen positioning notch, and the function of assisting in determining the position of the bolt hole is achieved.
The utility model has the advantages that:
the connecting piece is simple in structure, convenient to install, capable of preventing secondary damage to wood during installation, reusable, environment-friendly and economical.
By adopting the glued wood beam-column connecting piece, the connecting strength between glued wood beams and columns is enhanced, and the structural stability is improved.
By adopting the glued wood beam-column connecting piece, the effective connecting area between the connecting piece and the beam-column is increased, the problem that the wood is seriously damaged due to the fact that the traditional connecting mode is used for drilling and grooving is too large is solved, and the glued wood beam-column connecting piece is safer and more reasonable.
By adopting the glued wood beam-column connecting piece, the exposed area of the connecting piece is very small, the connecting piece can be effectively placed to be corroded, and the service life is prolonged.
By adopting the glued wood beam-column connecting piece, the building is more attractive due to the hidden design.
