Steel pipe fasteners are mainly used for construction pipelines, construction site support and safety protection support. Steel pipe fasteners are generally used in conjunction with fasteners. The frame pipe and fastener are combined to form a steel pipe scaffold. The frame pipe is an important part of the steel pipe fastener scaffold. In general, there are 91 scaffolding pipes per bundle.

So, what are the common problems in the use of steel pipe fasteners?

(1) Have a clear understanding of the load-bearing steel pipe scaffold. In general, if the floor thickness exceeds 300mm, it should be designed according to the heavy-duty scaffold. If the scaffold load exceeds 15kn/mm2, experts should be organized to demonstrate. It is necessary to distinguish which parts of the steel pipe length changes have a great influence on the bearing capacity. Formwork support should consider the upper free length a should not be too long, generally less than 500mm (the new specification can be modified). Generally, in the vertical rod calculation, the stress of the top and bottom steps is large and should be used as the main calculation point. When the bearing capacity is less than the requirements of this group, the pole shall be increased and the step distance shall be reduced.

(2) At present, the quality of steel pipes, fasteners, pipe jacking, and bottom supports of steel pipe racks in my country is generally unqualified. At present, in the actual construction, these factors are not considered in the theoretical calculation. The construction broom is missing, the vertical and horizontal joints are not connected, and the distance between the broom and the ground is too large or too small; The scaffold board is not listed, the thickness is not enough, and the lap joint does not meet the specification requirements; When the large formwork is removed, there is no anti-falling net between the thick inner rod and the wall. The diagonal brace is not set in the plane. The spacing of small crossbars under the scaffold is too large; fastener connection is loose, fastener slip, etc.

Steel pipe scaffold fastener is an indispensable product in construction, and this product has also been widely used. What problems should be paid attention to when using scaffolding fasteners? Now let's introduce what problems should be paid attention to when using steel pipe scaffolding fasteners? Let's introduce them one by one.

When installing the steel pipe scaffold fastener template bracket, the steel pipe fasteners used should be sampled before use. Of course, the quality and appearance of steel pipes and fasteners should be sampled, and the number of sampling inspections should be implemented in accordance with relevant regulations. Sampling inspection should be carried out according to a certain proportion. Those that have not been inspected or have passed the inspection shall not be used.

According to the appearance quality requirements of steel pipe scaffold fasteners, it is strictly prohibited to use sliding wire fasteners to detect the appearance quality of fasteners. When using these unqualified fasteners, if there are cracks, deformation, etc., to prevent construction errors and accidents.

Of course, in the process of using scaffolding, we should also pay attention to some problems in the use of scaffolding fasteners. It is forbidden to throw steel pipes and fasteners to the ground from high places. The loading and unloading of fasteners should also be careful and reasonable, and the loading and unloading and transportation of steel pipes and scaffolding fasteners should be effectively managed.
