[0074] Suspension beam 1 bottom masonry or inverted beam construction: Masonry below the height of the suspension beam 1 is built according to the conventional process requirements of masonry construction. When the masonry is built to the position of the suspension beam 1, a hole with a size reserved according to the position of the suspension beam 1 can ensure that the suspension mechanism 200 and the protective net 100 can be freely removed after the masonry construction is completed. The reserved hole is preferably a hole that can be constructed in an integral masonry to facilitate the quality of subsequent hole sealing.

[0075] Suspension beam 1 upper masonry construction: Masonry higher than the height of the suspension beam 1 is built according to the conventional process requirements of masonry construction.

[0076] Dismantling the construction of masonry protection device: after the masonry except the reserved hole is completely constructed and the strength of the mortar meets the requirements, the counterweight 42 is removed, then the suspension mechanism 200 is moved backward as a whole, the support 2 is moved to the reserved hole, the protective net 100 is removed from the reserved hole, the suspension mechanism 200 is extracted from the reserved hole and then removed; the suspension mechanism 200 of each layer is removed from top to bottom in turn;

A protective device for high-altitude edge masonry construction as described in claim 1, characterized in that, It also includes a sensor warning device (300), which is fixed at the bottom of the floor slab or under the structural beam near the edge of the floor slab, and is used to remind workers when they enter a certain range from the edge of the floor slab.

9. A construction method applicable to the high-altitude edge masonry construction protection device according to any one of claims 1-8, characterized in that: include: Install the suspension mechanism (200): Determine the installation height of the suspension beam (1) above the ground according to the waterproofing requirements of the floor slab masonry or the height of the flip beam, and adjust the depth of the upper bracket (21) inserted into the lower bracket (22) according to the installation height; place a counterweight block (42) with a total weight not less than the weight of the object or personnel during on-site construction on the counterweight rod (41) on the counterweight bracket (4); install no less than two sets of the suspension mechanism (200) on each floor according to the site conditions; Install the sensor warning device (300) and the protective net (100): Fix the sensor warning device (300) to the bottom of the floor slab or under the structural beam near the edge of the floor slab; connect the protective net (100) to the protective net connector (3) so that the protective net (100) fits against the edge of the floor slab; Construction of the bottom masonry or flip beam of the suspended beam (1): When the masonry is built to the suspended beam (1), the size of the hole reserved at the position of the suspended beam (1) should be such that the suspended mechanism (200) and the protective net (100) can be freely removed after the masonry construction is completed. Holes that can be used for the construction of the whole block of masonry should be reserved as much as possible to ensure the quality of subsequent hole sealing. Construction of the upper masonry of the suspended beam (1): Construct masonry above the height of the suspended beam (1) in accordance with the conventional masonry construction process requirements; Remove masonry construction protection devices: After all masonry construction except for the reserved holes is completed and the mortar strength meets the requirements, move the suspension mechanism (200) backward as a whole, so that the bracket (2) is moved to the reserved opening, remove the protective net (100), pull the suspension mechanism (200) out of the reserved opening and then remove it; remove the suspension mechanism (200) of each layer from top to bottom in sequence; Sealing reserved openings: The reserved openings are sealed with masonry and mortar of the same material.
