Assembled supporting frame for prefabricated stair performance detection

Abstract

The invention relates to an assembled supporting frame for prefabricated stair performance detection. The assembled supporting frame comprises a height-adjustable bearing beam. The bearing beam is used for bearing a prefabricated stair, and the two ends of the bearing beam are detachably connected with supporting pieces. The bottoms of the supporting pieces are detachably connected with stabilizing supports. The height of the bearing beam can be adjusted according to the height of a prefabricated stair component, the assembled supporting frame is suitable for prefabricated floor components with different sizes, the effect that the device is recycled is achieved, different supporting devices do not need to be designed for the components with different sizes, the detection cost of the prefabricated stair component can be effectively reduced. Moreover, the assembled supporting frame is simple in structure, convenient to use and low in manufacturing cost, all components can be disassembledand assembled to achieve the purposes of convenient transportation and on-site installation, rapidness and convenience are achieved, and therefore the completion efficiency of performance testing ofthe prefabricated stair component can be greatly improved, and the improvement of the construction production efficiency of a prefabricated building is promoted.

Description

technical field [0001] The invention relates to the field of fixing devices for structural performance inspection of prefabricated stairs, in particular to an assembled support frame for performance inspection of prefabricated stairs. Background technique [0002] In the current prefabricated concrete construction projects, there is no mature structural performance test method for prefabricated stairs. Some testing agencies use the in-situ static load test after the prefabricated staircase is installed, which actually breaks through the national standard "Code for Construction Quality Acceptance of Concrete Structure Engineering" GB50204, which requires "structural performance inspection when entering the site"; Some testing institutions propose to test the prefabricated stair components in a flat way to facilitate real load loading, but this is somewhat different from the actual working state of the stair components. [0003] At present, for the structural performance insp...

Problems solved by technology

[0003] At present, for the structural performance inspection of prefabricated stairs, it is necessary to temporarily design the support device suitable for the prefabricated staircase according to the size of the staircase and the test site. On the one hand, the specimen support device is difficult to reuse after the test is completed, resulting in waste
