Secret-related safety network
◇This project adopts rail of steel tube for each floor and secret-related network for protection. The space between two vertical poles of steel tube is 1.50m. The first horizontal pole is set 30 cm at the lower part of vertical pole with a space of 1.20 m. The battle footplate is set at lower opening inside and a secret-related network is hung outside, forming a stable fixture with frame and steel tube as following fig:
◇楼层洞口的防护
◇Protection of floor hole
本工程室内较大洞口需进行防护，采用钢管支设临边防护栏，高度1.20m，立杆间距1.20m，水平杆设两道，下部设18cm高竹胶合板挡脚板，防护栏杆挂密目网，洞口上面挂水平安全网。如下图：
This project shall protect relatively big holes indoors, adopting steel tube as a protection rail with a height of 1.20 m. The space between two vertical poles is 1.20 m. Two vertical poles are set and a battle footplate of bamboo veneer board high is set 18 cm at lower part, the secret-related network of protection rail and horizontal safety network is hung on month of hole as following fig:
钢管 Steel tube
挡脚板 Battle footplate
水平安全网 Horizontal safety network
楼层安装预留洞采用复合木模板覆盖防护，楼层钢筋不断，可以固定模板。如下图：
Install preserved hole with compound wooden molding board as a cover for protection at each floor. The reinforcing steel bar is used for fixing molding plate at each floor, which will not break off，seeing the following fig.
洞口上覆盖竹胶合板 Cover veneer board on the hole
用铁丝扎牢 Fasten with wires
防护洞口处结构钢筋不断 The reinforcing steel bar at protection hole will not break off
预留洞口处结构钢筋不断The reinforcing steel bar at preserved hole will not break off
后浇带水平防护采用复合木模板覆盖防护。如下图：
The latter-irrigated zone horizontal protect adopts compound wooden molding board as a cover for, seeing the following fig.:

The latter-irrigated zone covered with veneer board
防护闸口处结构钢筋不断
The reinforce steel will not break off at protection brake.
后浇带底模不拆
The bottom die of latter-irrigated zone will not be dismantled
◇电梯间的防护
◇The protection of elevator room
电梯间入口及层间均需作安全防护，在电梯入口用φ16钢筋焊接铁栅栏固定，并刷红白漆，悬挂好安全警示标志；电梯间每层作一道水平安全网防护。如下图：
The entrance of elevator and inter-floor need safety protection and φ16 reinforcing steel bar for steel rails should be fixed at the entrance of elevator, being painted with red and white paints and hanging a safety alarming sign; elevator room of each layer shall be provided with a horizontal safety network for protection as following:
铁栅门 Iron-barred door
安全网防护 Safety network for protection
每层均设 Set at each floor
电梯洞口防护 Protection of elevator hole
膨胀螺栓 Expansion bolt
◇安全通道防护
◇Precaution of safety channel
施工入口处的洞口防护采用钢管搭设双层防护棚，水平铺设竹胶合板，竖向用密目网封闭，包括施工电梯入口及施工人员出入楼内的通道防护均按下图施工。楼内安全通道主要利用楼梯，并作好安全指示牌，标明通道的方向。另外，在安全通道搭设及使用
彩色编织布 Colorful weaving cloth
50厚木脚手板 50 thick wooden scaffold
绿密目安全网 Green secret-related safety network
安全标识牌 Safety signs
通道 Passage
时，梁板支撑体系尚未拆除时，在安全通道的路线处的梁板支撑体系的水平杆需断开，安全通道高度不得低于1.80m，在安全通道两侧搭设斜撑进行加固。安全通道的搭设如下图：
在结构施工阶段，外用电梯入口处应搭设安全通道，与施工道路相通，并再搭设一个直接通至楼层的安全通道。
Cave protection of construction entrance applies double-deck shelter of steel tube; paved with bamboo plywood in horizontal direction, close-mesh network in vertical direction. The passage inside the building including the protection of construction elevator entrance and constructors entrance shall comply with the following draws. The exit passageways inside the building are mainly use staircase, and have safe sign for indicating the direction of the entrance. In addition, during the construction of safety exit passage, and the beam board supports system has not removed yet; and the horizontal pole that the exit passageway supports system in the route of the beam board needs disconnection, the height of exit passage shall not lower than 1.80m. Set reinforced stulls on both sides of exit passage. The picture of the exit passage as follows:
During the course of structure construction, the external lift entrance shall have safety entrance communicates with construction road; and set another safety exit passage directly communicated to the floor.
◇水平挑网
◇Horizontal overhanging network
为防止高空坠落，施工需搭设水平挑网，沿结构外周圈进行设置，自二层顶部设第一道水平挑网，安全操作规范要求每三层及不小于10米高度设一道；结合本工程的特点和实际情况，采取二层、四层设一道水平网。如下图：
In order to avoid something falling from high place, establish a horizontal overhanging network. Set the first one at the top of 2nd flood. The operation regulation is that one network shall be set every three floors and the height no less than 10 m as well; Combine the character of this project and actual situation, set network at the 2nd floor and 4th floor as following:
水平挑管，间距3m Horizontal cantilever pipe, space 3m
水平挑网 Horizontal cantilever network
外脚手架立杆 Vertical pole of outer scaffold
钢管斜撑，间距3m Slanting support of steel tube space 3m
