Bailey Panel Steel Bridge, Manufacturer Price

The steel temporary bridge leasing manufacturers briefly describe the characteristics of the steel temporary bridge:

The temporary steel bridge has the characteristics of light structure, convenient disassembly and assembly, and wide range of use. In order to let everyone know the steel temporary bridge best, today the steel temporary bridge leasing manufacturer briefly describes the characteristics of the steel temporary bridge.

The steel temporary bridge is welded by upper and lower chords, vertical rods and diagonal rods. The ends of the upper and lower chords are provided with male and female joints, and the joints are provided with a pestle holder connecting pin hole. The chord of the steel bridge is composed of two No. 10 channel steels (back-to-back). On the lower chord, a number of steel plates with round holes are welded, and the upper and lower chords are provided for connection with reinforced chords and double-layer trusses. There are four bolt holes in the upper chord for connecting the support frame, and the two holes in the middle are for connecting double or multi-row trusses with the same node. The two holes on the two ends are used to connect across the internodes. When multi-row steel temporary bridges are used as beams or columns, support frames must be used to reinforce the joints of the upper and lower steel temporary bridges.

The steel temporary bridge leasing manufacturers briefly describe the characteristics of the steel temporary bridge. On the lower chord, there are 4 beam pads, and there are tenons on the top to fix the position of the beam on the plane. The channel steel web at the end of the lower chord is also provided. There are two elliptical holes for connecting wind-resistant rods. The vertical rods of the temporary steel bridge are all made of 8# I-beam, and there is a square hole on the side of the vertical rod next to the lower chord, which is used for the beam clamp to fix the beam. The steel temporary bridge is made of 16Mn, and each frame weighs 270kg.

Does the Bailey bridge need to be disconnected when the Beret is removed?

Dismantling the berets as far as possible to disconnect the berets in the middle of the span, knock out the pins, and then use a crane to remove each group of berets in sequence. If it is not possible to disconnect and remove the berets, two cranes can be used to The Lei Pian shall be hoisted and removed as a whole. For the berets that cannot be directly hoisted and dismantled by the crane, they are pulled out synchronously by the inverted chain, and then hoisted and dismantled.

measure:

1. Do a good job in the re-testing of wire control piles, structure positioning piles, and leveling base points to ensure the accuracy of construction laying out.

2. The steel columns entering the site need to be randomly inspected to check the straightness and rust. Those with dents, bends or severe rust shall not be used. The thickness of the steel pipe shall not be less than 8mm. Steel pipes whose thickness does not meet the requirements shall not be used.

3. In the process of erecting the steel column pile, the 321 Bere steel bridge test is strictly controlled to strictly control the verticality. When welding, ensure that the weld seam is full, and use four 10*20*10 thick steel plates for welding.

4. When welding the H-beam and the steel column, the surface of the I-beam should be flat so as to be in close contact with the Bailey frame.

6. Dismantling H-beams. Use gas welding to disconnect the connecting parts of the I-beams and steel pipe columns, and use a 25t crane to hoist the I-beams at two points. The position of the lifting point must ensure that the I-beam can be hoisted in a balanced manner.

7. Removal of connection system and steel pipe column. With the cooperation of an excavator, the connection with the steel pipe is manually cut, and the connection system is removed; the steel pipe column and the foundation embedded steel plate are cut off, and the steel pipe column is removed.
