5.1 construction of the main process is as follows: sample frame installation, hanging datum line → rail frame and rail installation → machine room machinery and equipment installation → counterweight installation → car installation → floor door installation → shaft machinery and equipment installation → wire rope installation → electrical installation → machine debugging 5.2 construction method of the elevator installed in this project has no special requirements, in accordance with the ****/ZW-00*-2010 "traction elevator" construction process. 5.3 Construction method of each sub-project 5.3.1 Scaffolding erection method The scaffolding of elevator shaft is erected with steel pipes and fasteners, and the uprights and crossbars are connected with right-angle fasteners, and the fastening moment of the fasteners reaches 4-5kg.m. The ends of all the cross flutes of the scaffolding are braced tightly with the wall surface, and the distance between the four sides of the cross flutes and the wall surface, the distance between the balanced and counterweight side is 60cm, and that between the three sides is 40cm, and the clearance from the wall is 40cm, and the clearance from the wall is 40cm. The distance between the cross flute and the wall is 60cm on the balanced counterweight side and 40cm on the other three sides, and the spacing should be no more than 20cm from the wall at the gap of the wall, and the reinforcement of the spacing row should be no more than 20cm away from the wall surface, and the spacing of the scaffolding columns should be no more than 1.8m, and the spacing of the row should be 1.8m, and the spacing of the rows is 1.8m, and the spacing of the rows of cross flute is 20cm below the floor level, and the spacing of the cross flute should be 35 cm. Wall pre-buried mesh reinforcement diameter of not less than 14mm, rebar embedded length of not less than 30 times the diameter of the rebar. Safety net from the second floor, up every 10 meters (or three layers) set a safety net must be intact, firm and reliable. Elevator shaft protection safety net shall not be arbitrarily removed, to be installed when the elevator scaffolding, each ride to the height of the safety net can be removed. Scaffolding removal order should be carried out from top to bottom, remove the steel pipe, bamboo fence, etc. must be properly transported out of the elevator shaft, and prohibit littering and throwing. Facilities in the elevator shaft must be inspected and maintained regularly by scaffolding maintenance personnel, and hidden dangers should be eliminated in time. When setting up safety net and dismantling the facilities in the shaft, the operator must wear safety belt, and the hanging point must be safe and reliable.5.3.2 Lifting Methods5.3.2.1 Lifting Rigging and PrecautionsThe lifting machines and slinging apparatus used in the lifting process must comply with the relevant national standards, and all the lifting equipments must be used and maintained in accordance with the manufacturer's regulations. The actual load-bearing capacity shall not exceed the rated capacity of the components (e.g. elasticized shackles, hooks and loops, hooks, eyebolts and wire rope heads), which shall be used in accordance with the manufacturer's specifications (e.g. sleeves in the eye of the cable shall be used to protect it, the length of the sling shall not be shortened by tying knots or any other means, and the hooks shall be softly cushioned to prevent them from being damaged by sharp edges or bent at 90 degrees or more). (bending it at an angle of 90 degrees or more). The rope shall be passed through the pulleys to ensure that the lifting tension is applied to the center of each pulley and to prevent swaying, twisting and damage to the rope due to cutting of the rope by the edge of the pulley. Lifting personnel need to be licensed, in the process of lifting construction shall establish a unified communication system (such as sign language) and put into practice; all lifting equipment and rigging (such as cranes, wire ropes, hooks, etc.) must be put into use before the safety inspection, such as the existence of hidden safety hazards found in the problem should be discontinued immediately. All persons shall keep a safe distance from the suspended weights, and shall use tail ropes and guide ropes when the suspended objects may sway or pass through restricted areas.5.3.2.2 Lifting steps (1) Use flatbed trucks to transport the box pieces of elevator equipments to the site site in front of the reserved equipment lifting inlet; (2) Unload the elevator parts and components box pieces to the reserved site in the enclosure with the crane of more than 12 tons. The size of the large parts box of the incoming equipment: 2200×800 (cm), weighing about 500kg, the largest box is the elevator car bottom box 2200×1400 (cm), traction machine box: 800kg; (3) in the location of the reserved equipment lifting port, the elevator equipment whole box or split lifting to the installation of the corresponding floor required. (4) Install fixed winches and lifting sheave lugs with expansion bolts and steel wire rope pulling on the first floor, and the steel wire rope used for lifting passes through the pulley set set set at the top of the elevator shaft used for lifting, and the steel wire rope is rewound back to the entrance of the elevator shaft on the first floor; (5) Lift the whole box or disassembled parts of the elevator equipment into the machine room and the corresponding floor position with the winches after being firmly bound with the slings.5.3.2.3 Equipment to be Lifted (1) Equipment to be lifted and transported to the machine room: ① traction machine load bearing beam and fixing device; ② traction machine; ③ guide rope sheave and accessories; ④ control cabinet and driving cabinet; ⑤ speed limiter; ⑥ traction rope, speed limiter rope and rope head combination; ⑦ machine room wire channel and wiring. (2) Equipment to be lifted to the top floor: ① car frame; ② car wall and door; ③ car electrical parts box; (3) Equipment to be lifted to the intermediate floor: ① hall door; ② door cover; ③ floor slab; ④ door head combination. (4) Equipment to be transported to the lowest floor: ① Counterweight frame; ② Counterweight block; ③ Guide rail; ④ Guide rail bracket; ⑤ Pit part box. (5) Equipment to be carried to the warehouse: ① car control panel; ② call button; ③ entourage cable; ④ shaft cable; ⑤ fasteners. 5.3.3 Installation method of elevator components The installation method of each elevator's mechanical and electrical components shall be in accordance with the ****/ZW-00*-2010 "Construction Process of Trailing Elevator Installation". 5.3.4 Elevator debugging Elevator commissioning shall be in accordance with the methods of commissioning of the elevator, as per the provisions of ****/ZW-00*-2010 "Trailing Elevator Installation and Construction Process". **/ZW-00*-2010 "traction elevator installation construction technology" stipulates. 5.4 Implementation of process documents The process documents implemented in the installation project are composed of the following documents: ****/ZW-00X-2010 "traction elevator installation construction technology"; machine room layout, shaft layout; elevator commissioning manual; elevator parts installation diagram, electrical schematic diagram, electrical wiring diagram; elevator installation and maintenance diagram; elevator installation, electrical schematic diagram, electrical wiring diagram; elevator installation, electrical schematic diagram, electrical wiring diagram; elevator installation, electrical wiring diagram; elevator installation, electrical wiring diagram; elevator installation, electrical wiring diagram; elevator commissioning manual.
