[0002] A building expansion joint is a structural joint set at an appropriate position along the construction joint direction of a building or structure to prevent cracks or damage to the building components due to climate and temperature changes (thermal expansion and contraction). An expansion joint divides the building components above the foundation, such as walls, floor slabs, and roofs (except wooden roofs), into two independent parts, allowing the building or structure to expand and contract horizontally along the length direction.
[0003] However, expansion joints are usually narrow, with a width of 20 mm to 30 mm, which cannot provide a working surface for the installation and removal of the wall formwork on both sides of the expansion joints. During the construction of the aluminum film, the aluminum formwork at the expansion joint is difficult to adjust the position, and due to installation errors, gaps are likely to appear at the contact between the aluminum formwork and the exterior wall, resulting in leakage of slurry inside the expansion joint, which is difficult to seal.

[0008] Preferably, a plurality of through-wall tubes are fixed inside the steel cage, and the screw rods penetrate the through-wall tubes.
[0009] Preferably, a first fixing ring and a second fixing ring are respectively installed at both ends of the wall-penetrating tube, the interiors of the first fixing ring and the second fixing ring are both engaged with a sealing sleeve with a funnel shape inside, and multiple sealing sleeves are in contact with the side walls of the inner aluminum film of the exterior wall or the outer aluminum mold of the exterior wall.
