5.2 Requirements for construction machines, equipment and construction site

5.2. 1 Main machine tools:

Electric hammer, hammer, spirit level, square ruler, steel ruler, box ruler, wire pendant, Mo Dou.

Operating conditions:

1 The scaffold of the shaft has been completed, which meets the requirements of the Operating Rules for Scaffolding Safety Technology in Construction and Installation Engineering and the drawings provided by the installation department.

2. The highest point of the scaffold platform is located under the roof of the shaft: 1.5 ~ 1.7m, so as to stably place the formwork. It is best to use four short pipes for the riser of the top scaffold. After the short pipe is removed, the vertex of the remaining riser should be 500mm below the support of the highest floor to facilitate the installation of the car (Figure 5.2.2.2).

3 The span of scaffold pipe layout should be1.4 ~1.7m. To facilitate installation, a horizontal pipe should be set 200 ~ 400 mm below each layer of support, and a horizontal pipe should be installed between two horizontal pipes to facilitate climbing up and down. Scaffolding should be supplemented with at least 2/3 scaffolding boards at each step, and each floor should be staggered to reduce the risk of falling (Figure 5.2: At both ends of scaffolding, exhaust pipes 150 ~ 200mm are fastened with 8# lead wires (Figure 5.2.3.b).

Scaffolding must be checked and accepted by the safety technology department before it can be used.

5. The electricity used for site construction and lighting must meet the requirements of the national standard "Technical Specification for Safety of Temporary Electricity Use in Construction Sites".

6 doors at all levels must be equipped with good protective doors; Doors at all levels and scaffolding at every step should be kept clean and free of sundries.

7 The actual measurement of the height of the top floor and the depth of the bottom pit should be consistent with the drawings, and check whether it can meet the requirements of climbing the ladder without crossing.

6 construction technology

6. 1 process flow:

Erecting formwork frame → determining datum line by measuring axis → hanging datum line when formwork is in place.

6. 1. 1 Installation of sample rack:

1 angle steel is horizontally and firmly fixed on the shaft wall about 1.2m below the roof of the shaft with expansion bolts.

2 If the shaft wall is a brick wall, a hole should be dug in the horizontal direction about 1. 1m below the shaft roof, and the formwork wooden support should be placed firmly and fixed at both ends. 3. The square end of the sample holder shall be leveled, and the levelness error shall not be greater than 3/ 1000.

6. 1.2 Measure the axis and determine the standard line.

1 Pre-put two floor entrance line survey shafts. Generally, the distance between two lines is the net opening of the door.

2 according to the shaft measurement results to determine the baseline, should pay attention to the problem:

(1) Do the components installed in the hoistway, such as speed limiter steel wire rope, layer selector steel belt, limit switch, neutral box, cable hanger, etc., cause obstacles to the car operation? At the same time, the distance between the slide and sill on the car door and the distance between the counterweight and the wall should be considered. It is necessary to ensure that the clear distance between the moving parts of the car and counterweight and the static parts and building structures in the hoistway is not less than 30mm when running up and down.

(2) When determining the position of the trolley track line, the installation position should be considered according to the height requirements of the track frame.

(3) When determining the center line of the counterweight track, the counterweight width (including the counterweight block and the most prominent part) should be considered, and the clearance with the wall and the car should not be less than 50 mm ..

(4) For elevators with front and rear doors (through doors), the depth of the hoistway should be ≥ the width of the landing sill ×2+ the gap between the landing sill and the car sill ×2+ the car depth. And should consider whether the vertical condition of the shaft wall meets the installation requirements.

(5) Determine the threshold position of each floor, and measure the distance between each bracket and the line according to the door line of each floor. If you plan well, you must take care of the majority. It is necessary to consider less brackets or walls, and to stabilize the windowsill farthest from the wall. The gap between the doorpost and the upper wall is less than 30 mm ..

(6) For the elevator with marble door cover and decorative wall on the floor door building, the construction of door cover and decorative wall should be considered in addition to the consideration in (5) above when determining the floor door baseline.

(7) When installing two or more parallel elevators, attention should be paid to whether the center distance of each elevator is consistent with the architectural drawings. According to the construction situation of the shaft, the position of all landing door indicator lights and button boxes should be considered comprehensively, so that their heights are consistent, coordinated with the building and beautiful.

(8) When determining the baseline of several elevators that are relatively parallel, in addition to the above precautions, the width of the elevator waiting hall on both sides should be consistent according to the building and the door cover, and the doors of two elevator floors should be relatively consistent to ensure the aesthetic requirements of elevator door cover construction or civil marble door cover construction.

(9) When determining the baseline, the layout of the computer room should also be reviewed. Whether there is any problem in the layout of electrical equipment such as traction machine, I-beam, speed limiter, generator, limit switch and layer selector, and whether it is convenient for maintenance, make necessary adjustments.

6. 1.3 template in place, hang the baseline:

1 template processing and manufacturing. The wooden strips of the sample should be planed and straightened on all sides, assembled according to the requirements of the drawings, and the sample should be firmly fixed in place with glue.

In order to simplify the construction, the method of nailing battens directly on the wood square can be adopted instead of hanging the baseline with the whole template. However, the materials used must meet the requirements of the first section of this chapter.

2 No matter whether the formwork method or the straight nailing method is adopted, the center line of the elevator shaft, the center line of the car frame and the center line of the counterweight shall be determined after overall consideration according to the requirements of Article 6. 1.2 (Figure 6. 1.3. 1), and then the setting-off points of each reference vertical line shall be determined. When crossing a line, check whether it is correct with a thin pencil, and then recheck each diagonal line. The levelness of the battens on the formwork or wood square in the whole plane shall not be greater than 3mm.

3 At the formwork, hang the lighter objects at one end of the steel wire and slowly lower them into the pit in sequence. The middle of the vertical line cannot touch scaffolding or other objects, nor can the steel wire have a knot.

4 At the pay-off point, vertically saw or draw a small V-shaped groove with a saw blade or an electrician's knife, so that the apex of the V-shaped groove is the pay-off point, and pay-off is carried out to prevent errors caused by the displacement of the baseline, and the name of the line is marked at the pay-off point, and the tail line is firmly tied on the fixing nail.

5. After the line into the pit, replace the hanging object when paying off with a line pendant, and let it stand vertically naturally. If the trip is high or the wind is strong, it is difficult for the steel wire pendant to rest. You can put a bucket in the pit and put the steel wire pendant in water or engine oil to increase its swing resistance and let the steel wire pendant rest as soon as possible.

6 Fix the lower formwork with wood square support at 600 ~ 1000 mm of the pit, fix the line on the formwork wood with U-shaped nails after the baseline is fixed, and then check the size and diagonal of each setting-out fixed point on the formwork. After confirmation, proceed to the next process.

7.2 Stability and Verification of Reference Lines
