It should be understood that the embodiments described below with reference to the drawings are exemplary descriptions for explaining the technical solutions of the embodiments of the present application, and the technical solutions of the embodiments of the present application are not limited.
As used herein, "said" and "the" may also include plural forms, unless specifically stated otherwise, as will be understood by those skilled in the art. It should be further understood that the terms "comprises" and/or "comprising," when used in this specification of the present application, specify the presence of stated features, integers, steps, operations, and/or components, but do not preclude the presence or addition of other features, information, data, steps, operations, elements, components, and/or groups thereof, all of which may be implemented as desired in the art. The term "and/or" as used herein refers to at least one of the items defined by the term, e.g., "a and/or B" may be implemented as "a", or as "B", or as "a and B".
For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the embodiments of the present application will be described in further detail with reference to the accompanying drawings.

The following describes the related art:
The basic structural form of the conventional assembled floor steel pipe bracket which is commonly used in construction is that floor steel pipe pile columns are processed into standard sections in factories, and parallel connection and diagonal bracing are processed in the factories according to the design space of the steel pipe piles. Each standard section is provided with a matched steel anchor ear, and the stand column of the floor steel pipe pile is connected with the parallel connection and the diagonal bracing into a whole through the steel anchor ear.
The floor type steel pipe support has the defect that full-assembly type standardized construction cannot be realized. The spacing between the stand columns of the floor steel pipe piles mainly depends on the span of the pile-supporting beam at the upper end of the stand column, and different projects only aim at the beam body with a specific section because of different types and sections of the upper beam body and different loads acting on the pile-supporting beam, so that the spacing between the stand columns of the floor steel pipe piles is different. If the steel pipe pile is turned over to other projects, the space between the steel pipe pile columns is possibly different, so that the parallel connection and the diagonal bracing cannot be installed, the parallel connection and the diagonal bracing are required to be reprocessed according to project conditions, the turning over cannot be realized, and steel is wasted.
