Safe use and composition of ladders

Safety ladders must be maintained when they are in use, rust removed and painted together, and the colors strive to be beautiful. The scaffolding poles, protective railings, and skirting poles are painted yellow together, and the shear braces are painted orange red together. The bottom row of vertical poles and sweeping poles are painted in red and white. The following Hubei Wangke Template Co., Ltd. will give you a detailed introduction:

1. The glass fiber reinforced thermosetting composite material is mainly composed of glass fiber with reinforcing effect and bonding effect. Composition of thermosetting resin with load effect. The tensile strength of glass fiber is very high (3450mpa), and its content, length, and laying method determine the strength of the product. The strength of thermosetting glass fiber reinforced composite materials can be in the range of 30-1000mpa.

2, the installation is convenient. Directly built into the wall through the commodity pre-embedded device, positioning is accurate and strong, and the construction is very convenient.

3, no creep. The rigidity of the glass fiber reinforced thermosetting composite material ladder is doubled than other fiber reinforced materials, and it will not deform even under long-term load.

4, corrosion resistance. The glass fiber reinforced thermosetting composite material ladder is corrosion-resistant, acid and alkali resistant, and is especially suitable for use in humid, salt spray, acid and weak alkali environments.

5. Fire prevention. According to the application requirements, the composite material safety ladder developed by us has a very high oxygen index, which can reach 70% or more. It meets the safety requirements of fire prevention, low smoke, and halogen-free.

Sampling of steel pipes must be taken during the recycling construction of the safety ladder, and the steel pipes need to be sent to the relevant national qualifications The experimental unit conducts mechanical experiments such as steel pipe bending and tensile resistance, and the experimental effect can be used in construction only after it is satisfied with the planning needs.

Safety ladder composition and instructions

1. The adjustable base is inserted at the bottom of the pole to be used as a support system for horizontal, height and vertical adjustment and expansion The pressure-bearing surface, which transmits force to the foundation, is welded by the screw and the bottom plate. The adjustable base cannot be adjusted too high to avoid safety accidents caused by escaping from the vertical pole.

2. The pole is the main component that bears the vertical load. A row of pin buckles are welded on the pipe fittings of the vertical pole every 495 distances to install the cross bar, cross brace, or diagonal bar. The bolt is welded directly on the top of the pole to ensure no loss.

3. The crossbar is the horizontal load-bearing member of the frame. It is connected to the vertical rod through a pin library. Because the pin library is equipped with wedge iron, the connection between the two has good mechanical strength and high self-locking performance.

4. The cross brace is the horizontal bearing of the frame and is used to place ladders and footboard components. It is connected with the pole through the pin library.

5. Ladder is placed on the cross brace and used for the passage of construction personnel.

6. The foot pedal is placed on the cross brace and used for the construction of the passage and the bridge of the operating platform.

7. The diagonal bar is a component used to strengthen the entire frame. It is connected to the pin buckle of the vertical pole by a special oblique joint.

8. In order to ensure the safety of construction personnel, every 495 horizontal poles must be installed on the vertical poles, and both sides of the ladder are placed The handrails and the diagonal rods for safe climbing must also be placed on all sides to enhance the stability of the whole frame.

9. Safely climb a zigzag staircase with steps every 1.5 meters, every 4-5 meters Wall fasteners need to be installed, and the larger erection height is 100 meters.
