2, because the plane one chip force structure form of the right and wrong solid that support adopts, the resistance to overturning of support is more weak situation.Because according to mechanics principle, stressed member is only in that to consist of stereo structure its stability of when structure just stronger.
3, support is to be born by the internal thread silk tooth of expansion anchor and the external thread wire tooth of round steel suspension rod in the take root load power at place of floor, because the stressed sectional area of above-mentioned screw thread silk tooth is too small, thereby causes the support bearing load of this force way to be restricted.The maximum pipe diameter that disclosed this support can be born on the 118th page in the national building standard design atlas " indoor piping suspension and support 05R417-1 " just only is the DN200 specification.
4, various pipes is managed interior medium running temperature and the inconsistent phenomenon of ambient temperature because of existing in the building, thereby pipe telescopic displacement phenomenon can occur when operation.When the stability of support of pipelines is weak, then support also will produce distortion along with piping displacement.When if support is in this kind distortion for a long time, therefore plants distortion and can produce harmful effect to the safety of support the fatigue effect that timbering material produces.Promptly there is the weak defective of structural stability in above-mentioned support itself, and this harmful effect can not be ignored especially.
