What are the signs of safety problems in fiberglass scaffolding?

The safety of glass fiber scaffolding is a prominent problem in the process of construction safety production. In the process of the installation and removal of fiberglass scaffolding, capsizing and collapse caused by the overall or partial instability of fiberglass scaffolding, as well as serious casualties caused by falling from high altitude, often occur. The reason for the failure is that the erection process and application are not reasonable, there are artificial damage, raw material wear and other factors in the application process, and it is easy to collapse tragic drama. Therefore, it is very necessary to detect the danger as early as possible and prevent accidents.

 

 

What are the signs of safety problems in fiberglass scaffolding?

1, glass fiber scaffolding collapsed

(1) At the early stage of straight collapse, the omen is that the lower part of the frame body and the beginning of the long rod show lateral arch deformation, which is visible to the naked eye but easy to ignore.

(2) In the middle stage of collapse, the beginning of a vertical pole shows obvious multi-wave arch deformation from bottom to top, and there will be damage traces at the joints and joints of fiberglass scaffolding.

(3) In the late period of straight collapse, the abnormal movement of nodes and wall failure of fiberglass scaffolding began to appear, and some nodes and nodes of fiberglass scaffolding will appear serious damage.

2. Glass fiber scaffolding partially collapsed

(1) The early warning of local collapse is that some horizontal rods and foot boards of fiberglass scaffolding have obvious torsional deformation and destruction, and some joints of fiberglass scaffolding will have cracks or loose slips, which are visible to the naked eye but easy to ignore.

(2) The mid-stage prediction of local collapse continues the failure characteristics of the early prediction and continues to develop, the crack propagation or recession of the joint site is serious, and some of the joint points begin to explode and deform.

(3) In the later stage of local collapse, the omen is that the foot plate and horizontal rod begin to break or fall off, and part of the frame begins to seriously deform, with abnormal sound.

3, glass fiber scaffolding and multi-layer transfer trestle dumping

(1) The early omen of tipping is that the root of the column near the side of the conversion frame of the fiberglass scaffold begins to settle; Glass fiber scaffolding pole slightly to one side of the transfer frame; There is initial tensile, compressive or shear deformation at the wall connection.

(2) The mid-tipping omen continued the destruction characteristics of the early omen and continued to develop, and the upper part of the frame began to shake. In severe cases, the root of the pole will be significantly detached from its support pad or position.

(3) The late omen of tipping is that the upper part of the glass fiber scaffold falls off violently and gives out abnormal sound.

What are the main accessories of fiberglass scaffolding?

With the development of social economy, the construction industry is becoming more and more prosperous. As an indispensable tool for construction, glass fiber scaffolding has been in increasing demand in recent years. So what are the main accessories of fiberglass scaffolding?

1. The steel tube

Scaffold STEEL PIPE SHALL BE WELDED STEEL PIPE WITH OUTER DIAMETER OF 48 MM AND WALL THICKNESS OF 3.5 MM, OR WELDED STEEL PIPE WITH OUTER DIAMETER OF 51 MM AND WALL THICKNESS OF 3.1 MM. The larger length of the steel pipe used for the transverse horizontal bar should not exceed 2m; Other rod parts shall not be larger than 6.5m, and the maximum mass of each steel pipe shall not exceed 25kg, so as to be suitable for manual transfer.

2. The fastener

Forged cast iron fasteners should be selected for the scaffolding of steel pipe fasteners. There are three basic forms: right-angle fasteners for connecting straight steel bars, rotating fasteners for connecting parallel or oblique steel bars, and butt fasteners for connecting steel bars.

3. Scaffolding floor

Scaffolding can be made of steel, wood, bamboo and other materials, each weight does not exceed 30 kg. Stamping steel foot plate is a commonly used foot plate, generally limited to 2mm thick steel plate, 2-4m long, 250mm wide, the appearance should be non-slip. The wooden foot board can be made of cedar board or pine, the thickness is not less than 50mm, the length is 3~4m, the width is 200-250mm, both ends are equipped with galvanized steel wire hoop, to avoid damage to the end of the wooden foot board.

4. Even the wall

Even the wall pieces connect the columns to the main structure. It can be composed of steel pipes, fasteners or embedded parts, or it can be made of steel bars to make flexible wall sheets.
