Abstract

The invention relates to a supporting frame for performance detection of prefabricated stairs, which comprises a supporting column and a bearing beam, and further comprises a lifting device for driving the bearing beam to move, the lifting device is arranged on the supporting column, and the bearing beam is connected with the lifting device. The problem that inconvenience is brought to a user due to the fact that the adjusting speed of the supporting frame is low is solved.

Description

technical field [0001] The present application relates to the field of performance detection of prefabricated stairs, in particular to a support frame used for performance detection of prefabricated stairs. Background technique [0002] With the continuous development of the construction industry, various prefabricated parts appear in construction projects. Among them, prefabricated stairs are relatively common prefabricated parts, which are often used in house construction. In order to ensure the quality of prefabricated stairs, they need to be adjusted before use. Carry out performance testing, and during the performance testing process, the support frame for supporting the prefabricated stairs is essential. [0003] The Chinese patent with the publication number CN112008667A discloses an assembled support frame for performance testing of prefabricated stairs, which includes a height-adjustable receiving beam, and supports are detachably connected to both ends of the recei...
