Detailed Description

The following description of the embodiments of the present invention is provided by way of specific examples, and other advantages and effects of the present invention will be readily apparent to those skilled in the art from the disclosure herein.

As shown in fig. 1 and 2, the beam-slab connection node for the steel structure embedded ALC lath comprises an ALC lath 1, a reinforced concrete floor 2 (which is fixedly connected through a bolt 13), a steel beam 3, a frame beam 4, a connecting angle steel 5, a hook bolt 6 and a metal connecting piece 16 (shown in fig. 4) which is pre-embedded/manufactured on site in the reinforced concrete floor and is welded and fixed with the connecting angle steel 5, wherein the ALC lath 1 is flexibly connected to the connecting angle steel 5 through the hook bolt 6. The connecting angle steel 5 and the hook bolt 6 realize the installation operation of the wallboard from inside to outside, and the connecting angle steel 5 is used for limiting and preventing the outer wall from overturning outwards in the installation and use processes.

The ALC slat 1 preprocessing node is repaired by adopting caulking primary coat and caulking agent 8, and the base layer is leveled by plastering mortar in a follow-up unification mode.

Wherein, the ALC slat 1 directly saws and has the notch that is used for connecting, and the fluting is moderate to increase and is favorable to the installation of metal connecting piece to hold.

Wherein, the horizontal joint of the ALC ribbon board 1 and the reinforced concrete floor 2 and the mounting hole of the ALC ribbon board connecting piece are respectively treated by an external wall special sealant and a bottom coat 11, a special hole repairing sealant and a bottom coat 11.
