[0019] Flexible wind shield curtains 204 are respectively arranged at one ends of the two rainproof cloths 201 away from the skirt parts 202. The wind shield curtains 204 are placed on both sides of the rainproof top cloth 2. The wind shield curtains 204 can be partially extended under the action of wind force to reduce the damage to the wind shield curtains 204 caused by wind and rain invasion.

[0020] Below each waterproof cloth, several rows of support skeletons 4 are respectively arranged. Each support skeleton 4 is composed of a fixed vertical rod 404, a connecting vertical rod 401 and a top cross bar 407. At one end of each support skeleton 4 far from the connection position of the two rainproof cloths 201, the connecting vertical rod 401 is respectively used to connect with the protective vertical rod 6 in the slip form system. At one end close to the connection position of the two rainproof cloths 201, the fixed vertical rod 404 is used to connect with the portal frame 1.

[0021] At both ends of the connecting vertical rod 401, sleeves 402 are respectively arranged. One end of the sleeve 402 is fixedly connected with the connecting vertical rod 401, and the other end is radially provided with a positioning hole 403 on its pipe wall.

[0022] At the upper end of the fixed vertical rod 404 and the upper end of the protective vertical rod 6 placed at the top in the slip form system, pin holes 406 are respectively opened; at positions close to both ends of the top cross bar 407, connecting rods 408 are respectively arranged, and pin holes 406 are also opened on the side wall at the lower end of the connecting rod 408.

Corresponding to the installation positions of the fixed seats at both ends of the portal frame 1, connection bolts 9 are respectively reserved. The base 405 is connected with the portal frame 1 through the connection bolts 9.

[0024] On the lower surface of each rainproof cloth 201 and the inner surface (the side close to the portal frame 1) of the rainproof side cloth 3, fixing buckles 8 are respectively arranged at intervals. At the upper end of the top cross bar 407, anchors 7 are arranged corresponding to the fixing buckles 8 on the lower surface of the rainproof cloth 201 connected thereto. On the outer walls of the sleeves 402 at the upper and lower ends of the connecting vertical rod 401, anchors 7 are also arranged corresponding to the fixing buckles 8 on the inner surface of the rainproof side cloth 3. The fixing buckles 8 are connected with the anchors 7 through a connecting rope (the connecting rope can be a rope or a wire).

[0025] After the slip form project is installed and before the slip form construction, according to the bolt positions reserved on the cross beam of the on-site portal frame 1, the fixed vertical rod 404 is installed, and then the connecting vertical rod 401 is installed on the fixed vertical rod 404 and the protective vertical rod 6. Finally, the top cross bar 407 is installed; after the support skeleton 4 is installed, the rainproof cover is installed. The rainproof side cloth 3 is installed on the outside of the connecting vertical rod 401 above the protective vertical rod 6, and the fixing buckles 8 and the anchors 7 are tied well through a connecting rope. The two rainproof cloths 201 are correspondingly installed above the top cross bar 407 of the support skeleton 4, and the fixing buckles 8 and the anchors 7 are tied well through a connecting rope, and the rainproof cover is installed. During the concrete pouring construction, it can be selected according to the on-site requirements whether the skirt 202 between the two rainproof cloths 201 needs to be opened or partially opened.

[0026] Based on the above device, the specific construction steps of the rainproof construction method for continuous slip formwork engineering are as follows: S1. Determine the spacing of the portal frames 1 in the slip formwork system according to the size of building structures such as silos and chimneys. At the same time, determine the spacing of the outer protective vertical poles 6. Determine the spacing of the support skeletons 4 according to the spacing of the portal frames 1 and the protective vertical poles 6. First, connect and fix the fixed vertical poles 404 to the portal frames 1, and then install the connecting vertical poles 401 on the fixed vertical poles 404, and install the connecting vertical poles 401 on the protective vertical poles 6. In this embodiment, the support skeletons 4 are made of aluminum alloy, stainless steel or galvanized steel pipes.
