What is the height of the edge protection in the new building regulations? The so-called is the height of the floor edge protection!

"Residential Design Code" GB50096-2011, 5.8.2 When setting up bay windows, the following regulations should be met:

1. When the window sill height is less than or equal to 0.45m, the protection height It should not be less than 0.90m from the window sill surface;

2. When the net height of the openable sash window opening from the window sill surface is less than 0.90m, protective measures should be taken at the window opening. The protection height should not be less than 0.90m from the window sill surface;?

3. Bay windows should not be installed in severe cold and cold areas.

Safety requirements for floor edge construction:

1. Safety production requirements:

① Safety helmet, safety Sanbao protective equipment such as belts and safety nets must use provincially registered products (for registration information, please refer to the list of registered products for construction safety protection equipment and machinery and equipment), and have product certificates, production licenses, and recommendation certificates at or above the provincial level.

② You must wear a safety helmet correctly when entering the construction site, and wear it throughout the entire construction process, especially during the completion of the main body and decoration.

③ When working at high places, in the air, on ladders, etc., if there are no other protective measures, safety belts must be worn. The safety belt should be hung vertically. It is safer to hang it high and low. Seat belts should generally be scrapped after five years of use.

2. Four-port and five-edge protection: The 150cm opening is made of steel bars that penetrate the concrete slab to form a protective net. The spacing between the steel grids shall not be greater than 20cm; bamboo plastic boards or scaffolding boards can also be used for sealing. Death cannot be moved.

For openings and inner patios with a length of more than 1.5m, a safety net must be hung, protective railings must be added around the perimeter, and warning signs must be hung. strict).

① Made of steel bars with a side length of 50cm and 16mm, with a spacing of no more than 15cm, and warning signs hung. Protection methods in the elevator shaft: Set up a safety flat net every two floors (not more than 10 meters) in the elevator shaft. There should be no debris in the flat net. The distance between the net perimeter and the wall should not be greater than 10cm. When the protection height exceeds one standard layer, no safety net should be installed. Use hard materials such as scaffolding boards for horizontal protection.

The protective flat net is high on the inside and low on the outside, with a height difference of 1-1.2 meters. First, it can reliably fix the protective flat net and prevent it from sliding down. Second, it can enable falling objects to slide toward the hole. F18mm, vertical grid F

② Elevator door openings must be equipped with protective doors. Tool-type gates should be used, with a height of 1.2 meters and borders

③ Foundation pit, floor, and roof facing edge guardrails Two channels should be set up, the upper pole should be 1.2 meters above the ground, and the lower pole should be 0.5-0.6 meters above the ground. The distance between poles should be no more than 2 meters, and foot guards or vertical nets should be set up. Protective railings should be made of steel pipes, which are strong and reliable, and painted with red and white warning colors.

④ The stair guardrail adopts tool-type protection. The vertical pole is made of Φ48 steel pipe with 100×100×8 iron parts welded at the lower end and fixed to the stair side plate or shear wall with 4 expansion bolts. Φ14 steel bar welded with 2 hooks.

The surrounding frame of the protective railing is made of Φ18 steel bars, and the middle reinforcement rod is made of Φ14 steel bars. It is hung on the pole hook and is tied firmly with iron wire when in use; an 18cm barrier painted with red and white warning ribbons is set at the bottom. The feet are closed.

3. Construction electricity

① Electrical products such as distribution boxes, electrical components and cables purchased and used at the construction site must undergo national 3C certification and provincial construction industrial product registration. , substandard products shall not be used.

② The space in the power distribution room should be set according to the capacity of the power distribution cabinet. The width of the operating channel and maintenance channel should meet the specification requirements. The door should be opened outwards for ventilation and measures to prevent rodent entry. It is strictly prohibited to use high-power electrical appliances in the power distribution room, and no idle personnel are allowed to enter. A sand box and a fire extinguisher for extinguishing electrical fires should be installed outside the power distribution room.

③ The temporary electricity layout and installation at the construction site must comply with the principles of TN-S zero protection, three-level power distribution, two-level leakage protection, separate power and lighting, and environmental safety. The power distribution of each electrical equipment must implement the "one machine, one gate, one leakage, one box" system.

④The number of repeated groundings of the protective neutral line of the power supply and distribution system at the construction site shall be no less than 2n 1 (n - represents the total number of branches), which shall be set at the head, middle and end of the power distribution system respectively. . The grounding device can make full use of the steel structure in the reinforced concrete foundation, and its grounding resistance should not be greater than 10Ω. The locations for repeated grounding can be:

(1) At the main distribution box (distribution cabinet);

(2) At each branch distribution box;

p>

(3) The switch box of the electrical equipment at the farthest end of each branch;

(4) Large construction machinery and equipment such as tower cranes, construction elevators, material hoists, and concrete mixing stations At the switch box.

⑤ The electricity used in temporary construction facilities should also meet three-level power distribution and two-level protection. The height of lamps and lanterns that do not use safe voltage should be no less than 2.4 meters from the ground. ?
