The Analysis of unqualified scaffold couplers

1) the right Angle coupler is mainly shown as the anti-slip performance, and the repeated use of the scaffolding coupler is related to the performance degradation.

2) rotating coupler main show is to break the resistance is poor, part of the scaffolding coupler even in less than 5 kn damage (standard for 17 kn), and damaged parts link rotating shaft parts, mostly with the fastener materials used, and links to repeatedly use the axis of rotation partly loose deformation.

3) the main performance of the butt is the poor tensile performance, and the repeated use of the coupler is related to the loose deformation of the buckle.

4) appearance signs are generally incomplete, mainly manifested as: no date, no specification model, no trademark, resulting in quality problems that cannot be traced back to the source. Therefore, repeated use, casual maintenance, replacement of the fittings of the coupler, make the performance of the coupler greatly decreased, has not been able to meet the expected use purpose and the corresponding standard requirements.

2 The issues to be concerned

According to the feedback information from the sampling work, part of the enterprise quality consciousness is weak, not strong sense of responsibility, and part of the rental companies a repeat of the recycling use of poor quality coupler, not only seriously threatened the life safety of construction workers, but also disturbed the normal production of qualified products and sales environment. Therefore, the quality of product quality supervision department or production and processing enterprises and leasing market are a long - term work.
