Gantry steel pipe scaffolding, portal steel pipe scaffolding erection full scaffolding?

Aluminum alloy scaffolding generally refers to the quick-installation aluminum alloy scaffolding, which adopts a modular design, so that ordinary users can quickly and safely build a scaffolding working tower. Aluminum alloy scaffolding can be divided into single-width aluminum alloy scaffolding (double-width aluminum alloy scaffolding (.) According to the type of construction, it can be divided into straight ladder frame, oblique ladder frame, diagonal ladder frame, and combination tower.

When purchasing aluminum alloy scaffolding, it is first necessary to determine the height of the platform according to the construction height, for example, the construction height is 8m, then the platform height can be. It should be noted that the height of a single tower of aluminum alloy scaffolding shall not exceed 12m, and the height of a composite tower shall not exceed 20m. Secondly, it is necessary to determine which width of aluminum alloy scaffold to choose according to the construction site, and if the width is lower, you can choose to customize the special aluminum alloy scaffold.

Gantry steel pipe scaffolding is also called mobile portal scaffolding, movable scaffolding, which can be used to build a construction platform for interior and exterior wall decoration, up to 24 meters high, if you want to build such a high, it is recommended to use a thicker thickness.

Gantry scaffolding is one of the most widely used scaffolding in construction scaffolding. Because the main frame is in the shape of a "door", it is called a portal or portal scaffolding, also known as an eagle frame or gantry. This kind of scaffolding is mainly composed of the main frame, the horizontal frame, the cross diagonal brace, the scaffold board, the adjustable base, etc.

This kind of scaffolding is mainly composed of the main frame, the horizontal frame, the cross diagonal brace, the scaffold board, the adjustable base, etc.

Gantry scaffolding was first successfully developed by the United States, which has the characteristics of simple disassembly and assembly, good bearing performance, safe and reliable use, and has developed rapidly.

By the 60s, Europe, Japan and other countries successively introduced and developed this kind of scaffolding.

1.Before installing the full scaffolding, the vertical and horizontal position lines of the mast should be popped up on the floor or ground and leveled.

2.The span and spacing of the gantry should be determined according to the actual banquet cluster load, and the general spacing should not be greater than.

3.The cross support should be set on both sides of each row of masts, and should be locked with locking pins and mast poles, and should not be removed at will during construction.

4.Horizontal scaffolding or scaffolding should be set at every step. The top step operation layer should be covered with scaffolding, and should be fixed with the mast beam in a reliable connection mode, and the gap greater than 200mm should be hung with a safety flat net.

5.The horizontal reinforcement rod should be continuously set up every 5 columns and 5 rows of length at the top floor, bottom floor and middle of the full scaffolding, and should be fastened with the gantry rod by buckle bending answers.

6.The scissor brace should be set at intervals of 15m between the outer periphery and the inside of the full tripod, the width of the scissor brace should not be greater than 4 spans or spacing, and the inclination angle between the oblique rod and the ground should be 45° 60°.

7.The distance between the full scaffolding and the edge of the wall or other structure should be smaller, and railings should be set around it.

8.When a passage is arranged in the middle of the full scaffold, the bottom mast at the passage may not be provided with a horizontal reinforcement rod in the longitudinal (horizontal) direction, but a horizontal reinforcement rod should be arranged at each step in the upper part of the channel. Diagonal braces should be provided with masts on both sides of the channel.

9.When the height of the full scaffold exceeds 10m, the lock arm should be set between the upper and lower gantry, and the throwing brace or cable wind rope should be set on the outside to tie firmly with the ground.

10.The erection of full-hall scaffolding can be carried out by means of row-by-row and layer-by-layer erection, and safety protection components such as scissor braces, horizontal and longitudinal reinforcement rods, throwing braces (or cable wind ropes) and channel plates should be set up along with the erection.

11.When erecting and dismantling full scaffolding, scaffolding boards should be laid on the construction operation floor, and workers should wear safety belts.

12.After the assembly of the full house scaffolding is completed, the acceptance inspection of the following contents should be carried out:

1) Mast setting;

2) The configuration of cross supports, horizontal frames and horizontal reinforcement rods, scissor supports and scaffolds;

3) Mast crossbar load status;

4) The extension length of the base and the jacking screw rod;

5) Fastener tightening torsion;

6) Skid case;

7) Safety net settings.

Summary. Gantry steel pipe scaffolding generally uses flat iron scaffolding, also known as portal scaffolding. This kind of scaffold board is stamped from steel plate, and the surface is treated with anti-slip, which has the characteristics of anti-slip, wear-resistant, and corrosion-resistant.

The length of the portal scaffold board is generally 2 meters, the width is meters or meters, and the thickness is generally or. The edges of the portal scaffold board are curved, which can effectively avoid worker injuries. The connection between the portal scaffold and the portal steel pipe scaffold is snap type, which can be quickly and safely fixed on the scaffolding.

When using portal steel pipe scaffolding, the appropriate specifications and quantities of portal scaffolding should be selected according to the actual situation to ensure the stability and safety of the scaffolding.
