Adjustable prefabricated stair and prefabricated floor slab static load test supporting system

Abstract

The invention discloses an adjustable prefabricated stair and prefabricated floor slab static load test supporting system, which belongs to the technical field of concrete engineering tests, and is characterized by comprising a base, a movable supporting platform with a first supporting part is arranged on the base, and a mounting assembly is arranged between the movable supporting platform and the base. The base comprises at least two foundation bases, a plurality of extension unit bases are arranged between the adjacent foundation bases, first connecting assemblies are arranged between the extension unit bases and the foundation bases, and second connecting assemblies are arranged between the adjacent extension unit bases. A stand column is arranged on the foundation base, and a supporting connecting rod is fixedly arranged between the stand column and the base. A vertical rod with a second supporting part is arranged on the stand column, a lifting assembly is arranged between the stand column and the vertical rod, and the lifting assembly allows the vertical rod to ascend and descend to change the height of the second supporting part; and a plurality of detection instrument fixing frames are further included, and the effect of supporting prefabricated stairs and prefabricated floor slabs of various types is achieved.

Description

technical field [0001] The invention relates to the technical field of concrete engineering tests, in particular to an adjustable prefabricated staircase and prefabricated floor static load test support system. Background technique [0002] During the construction of the project, in order to effectively achieve many goals such as convenient construction, energy saving, and high safety performance, thereby reducing the environmental impact of construction, and finally meeting the requirements of green, environmental protection, and energy conservation advocated by the country, more and more Prefabricated buildings are put into use. [0003] The static load test measures the strain of steel bars and concrete during the loading process of prefabricated components, and describes the generation and development of concrete cracks, the stress of steel bars, and the characteristics and forms of the final failure when it reaches the critical state. A direct way to understand the nor...

Problems solved by technology

[0004] The above existing technical solutions have the following defects: in the actual use of prefabricated stairs and prefabricated floors, there will be many different models, and different models correspond to different sizes, so when each pair of prefabricated stairs or prefabricated floors is tested, It is necessary to build a support frame on site, resulting in a great waste of labor and materials
