[0016] The technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. The preferred embodiments in the description are only used as examples, and all other embodiments obtained by those skilled in the art without making any creative work are within the scope of protection of the utility model.
[0017] like Figure 1-Figure 3As shown, this specific embodiment adopts the following technical scheme: it includes a tension anchor assembly 2, a steel pipe 3, a steel wire rope 4, a safety flat net 5 and a flat net pull rope 6; the tension anchor assembly 2 is fixed on the structural plate 1, and the adjacent tension anchor assemblies 2 distributed laterally are connected by the steel pipe 3, and the end of the steel pipe 3 is inserted in the ear plate 2-1 in the tension anchor assembly 2 and fixed by a bolt assembly; the adjacent tension anchor assemblies 2 distributed longitudinally are connected by a steel wire rope 4, the steel wire rope 4 is a 10# steel wire rope, the steel wire rope 4 is inserted in the two steel wire rope insertion plates 2-2 in the tension anchor assembly 2, and is fixed by a double semicircular anchor clamp 2-3; the safety flat net 5 is placed above the structural beam 8, and the periphery is connected to the steel pipe 3 by a plurality of flat net pull ropes 6, and a hard mobile platform 7 is arranged on the safety flat net 5.
[0018] The manufacturing and installation method of the utility model is as follows:
[0019] 1. The laser cutting method is used for plate cutting to ensure the consistency of size. Each finished plate after cutting must be clearly marked;
[0020] 2. The pipes are cut with a toothless saw according to the actual size measured on site. The safety net 5 and 10# steel wire rope 4 are purchased from the market, and the tension anchor assembly 2 is rented;
[0021] 3. The tension anchor assembly 2 is transported to the site and transported vertically to the installation site by a tower crane or a passenger and cargo elevator. First, the dimension flush with the column edge is measured from the side beam of the space opening structure beam 8 to the outside, and the line is drawn. Generally, it is controlled to be 100mm outside the column edge. Then, the grid is divided at a spacing of 1.5-2m. When encountering a column, it needs to be avoided. After all the divisions are completed, the tension anchor assembly 2 is installed. The tension anchor assembly 2 is placed on the control line, and a mark is marked with a pen to drill holes. After all 6 holes are drilled, the tension anchor assembly 2 can be placed, and then the screw cap is tightened. This is repeated until all tension parts are installed.
[0022] 4. Then thread the 10# steel wire rope 4. After one end passes through the tension anchor assembly 2, tie the nylon rope prepared in advance and let the personnel at the other end pull it manually until it reaches the tension anchor assembly 2 at the other end and passes through the steel wire rope insertion plate 2-2, ensuring that each end has an exposed head of no less than 100mm. Then clamp one end with the double semicircular anchor clamp 2-3, and use a tensioning machine to tension the steel wire rope 4 at the other end until it is straightened and tight. Generally, the tensioning force can be controlled at 3KN, which can be adjusted according to the actual use on site;
[0023] 5. Cut the 50×5 steel pipe 3 according to the size measured on site and install it between the two tension anchor assemblies 2, and use M10 long bolts to cap it to prevent it from slipping;
[0024] 6. Lay the safety flat net 5: The holes of the flat net are made of a special net of 70-100mm. Nylon ropes (flat net pull ropes 6) are used to tie the net around. The other end of the nylon rope is firmly tied to the 50×5 steel pipe 3 at the tension anchor assembly 2. Canvas ropes are used to tie the net every 500mm, and special clamps can also be used for fastening;
[0025] 7. Carry out physical test. Use a 100KG sandbag to throw down from the roof to see if the wire rope is broken or deflected more than 200mm, and if there is any crack in the flat net. If necessary, correct the tension and replace the specifications of the safety flat net 5. If all the test requirements are met, it can be put into use. There should be no less than 3 test points.
