Description

 Concealed profile beam and column connection structure

 The invention relates to a building frame structure, in particular to a concealed profile beam and a column connecting structure.

Background technique

 Existing aluminum alloy beam-column structures that are easy to disassemble and need to be repeatedly built, such as the two-story exhibition structure of temporary buildings, may have horizontal sway due to poor rigidity of the beam-column joints, and even cause horizontal disturbance and instability. Case. The main reason for the poor rigidity of beam-column joints is: Temporary construction of beam-column structures can not be welded or riveted, and because of the open space or aesthetic requirements, too many cross linings or diagonal linings cannot be added. Most of them use τ-shaped connectors. Make a connection. The following problems exist with the T-type connector:

 (1) Spaces must be reserved at the joints of beams and columns. Otherwise, the joints of the joints of the joints may not be installed, and the joints of the joints of the beams and columns may be empty, which will inevitably reduce the rigidity of the joints of the beams and columns.

 (2) There is a gap between the screw hole and the bolt at the top of the T-type. The friction between the beam and the column is fixed by the bolt, and displacement occurs under the action of external force. Especially in the case of horizontal force interference, the beam will rotate along the bolt at the center of the top end of the T-shaped connector (see Figure 2). Even with double beams, this rotation is difficult to avoid.

 (3) When the T-connector is pre-mounted on the beam, the total length of the beam is greater than the column spacing; when the T-connector is pre-mounted on the column, the spacing is smaller than the length of the beam; when the two columns are fixed and fixed, The beam, especially the T-connector, is difficult to install or remove when installed in the interior of the beam.

 CN 201981700U discloses a "beam-and-column structure", which comprises a beam-column body and a connector inserted into the beam-and-pillar body, the main body of the beam-column body is provided with a body connecting fastener, and the side of the connector is provided with a plug The connecting fastener is connected to the connector connecting fastener by a fastening connection, and the connector is fixed in the beam and column body. The structure is simple and easy to install, and is mainly suitable for various housing structures, especially the connection of beams and columns of the sun room. However, it is not suitable for the connection of beams and columns that are easy to disassemble and need to be built repeatedly.
