Detailed Description
As shown in fig. 1, 2 and 3, in a large-hole safe closed construction platform for a building, at least two groups of horizontal stress brackets 1 are symmetrically arranged on concrete walls 6 or concrete beams 7 on two opposite sides of the large hole of the building, and three groups of stress brackets are arranged in the embodiment. The inner end joints of each group of symmetrical stress-bearing supports 1 are in mutual abutting joint, the joint abutting joint sections are connected through connecting fixing clamps 4, and two connecting fixing clamps are used in the joint abutting joint sections in the embodiment, so that stable connection, safety and reliability are guaranteed. The shaping plane protection plate 2 is installed on the top surface of the stress support in a tiled mode, the connecting pin 5 penetrates through the shaping plane protection plate 2 and the stress support 1, and the shaping plane protection plate is fixed on the stress support 1. The edge seam protection plate 3 is connected between the edge of the shaping plane protection plate 2 and the concrete wall 6 or the concrete beam 7 to completely seal a large hole in a building to form a safe construction plane, and the edge seam protection plate 3 is connected with the shaping plane protection plate 2 through a hinge 3 a.
