Among them, one side of the wall-end fixed main beam 1 is connected and fixed to a pre-embedded sleeve 5 embedded in the outer wall through a frame fixing support 6, and the other side thereof is connected to the inner long side of the horizontally arranged cantilever standard flat plate 2 through a flat plate fixing member 7. The protective baffle 4 is vertically connected to the outer long side of the cantilever standard flat plate 2 away from the wall-end fixed main beam 1. The adjustable diagonal rod 3 is obliquely connected between the cantilever standard flat plate 2 and the outer wall, one end of the adjustable diagonal rod 3 is connected to one end of the outer long side of the cantilever standard flat plate 2, and the other end thereof is connected to the pre-embedded sleeve 5 embedded in the outer wall through a U-shaped connecting ear screw 11.

[0033] The flat plate fixing part 7 is welded together with two parts, one of which is an angle iron 71 connected to the wall end fixing main beam 1. The vertical part of the angle iron 71 has a groove for the wall end fixing main beam 1 to pass through, and the horizontal part is provided with holes for the two ends of the opening of the U-shaped ring 16 to be inserted, which is used to fix the wall end fixing main beam 1. The other part of the flat plate fixing part 7 is a C-shaped steel plate 72 formed by using a steel plate to be arranged in a C shape. The back of the C-shaped steel plate 72 is connected to the angle iron 71, and the two parallel steel plates have holes for bolts to pass through. The inner long side of the cantilevered standard flat plate 2 is placed in the inner cavity of the C-shaped steel plate 72 and fixed with bolts. A haunch steel plate is welded between the two parts of the flat plate fixing part 7 to play a fixing role.

The two internal thread diagonal rods 12 are connected to the adjustable screw 13 by threads, and the non-threaded portion in the middle of the adjustable screw 13 is hexagonal, and a hole is opened in the middle of the non-threaded portion, so that a stick can be inserted into the hole and rotated to make it more convenient and quick for workers to adjust the length of the adjustable diagonal rod 3. The connected adjustable diagonal rods 3 are connected to the U-shaped connecting ear screw 11 through the reserved connecting ear, and the adjustable diagonal rod 3 is fixed to the outer wall through the U-shaped connecting ear screw 11 and the embedded sleeve 5. The outer ends of the two internal thread diagonal rods 12 are provided with connecting ears to facilitate fixing with the U-shaped connecting ear screw 11 at the wall end and the connecting ears on the cantilevered standard flat plate 2. The internal thread diagonal rods 12 at both ends of the adjustable diagonal rod 3 can be universal, with internal threads reserved on one side and connecting ears welded on the other side.

[0038] In the present invention, the bottom of the protective baffle 4 is mounted on the cantilever standard flat plate 2 through a connecting ear, and the top is fixed to the middle of the cantilever standard flat plate 2 by a guardrail diagonal brace 14.

[0040] There are connecting ears 17 on the upper and lower sides of the protective baffle 4, and connecting ears are provided in the middle and both sides of the upper part. The connecting ears on both sides are used to connect multiple protective baffles 4, and the connecting ear in the middle is used to connect the guardrail brace 14; the lower connecting ear 17 is mainly used to connect the cantilevered standard plate 2.
