Composite beam and composite beam and column joint connecting device

Abstract

The invention relates to a composite beam. The composite beam comprises a shell and a core. The shell is a column with a double-homocentric-square-shaped section. The shell is made from aluminum, andthe material of the core is different from the material of the shell. A composite beam and column joint connecting device comprises the composite beams, a supporting column and a connecting support, and the horizontal composite beams are arranged on the upper portions of the four side faces of the supporting column correspondingly. A cross-shaped opening is formed in the upper end of the supporting column, and rectangular grooves are formed in the end faces, attached to the supporting column, of the composite beams. The rectangular grooves communicate with the tail ends of the cross-shaped opening correspondingly. The connecting support is inserted into the cross-shaped opening of the supporting column and the rectangular grooves of the composite beams. The support and the supporting column are connected through screws, and the connecting support and the composite beams are connected through screws. The composite beam and the composite beam and column joint connecting device aim at solving the problems the an existing steel beam is exposed to the external environment and is poor in corrosion resistance, existing beams and columns are in joint connection, the joint is unbalanced instress, connecting screws are likely to be damaged, a connecting plate is likely to be bent, deform and crack, and connection of the beams and the columns are not firm.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a composite beam and a joint connection device between a composite beam and a column. Background technique [0002] Beams support the entire weight of the components in the upper frame of the building and the roof, and are the most important part of the upper frame of the building. Beams must have good bending resistance, firmness, and corrosion resistance. [0003] Existing beams generally adopt steel structures, which are exposed to the external environment and have poor corrosion resistance; the existing beams and columns are connected by joints, and the connecting plates are fixed on the outside of the beams and columns by screws. Due to high stress concentration, the screws are easily damaged, the connecting plates are prone to bending deformation and cracking, and the connection of beams and columns is not firm.
