[0054] The embodiments of the present application will be described below with reference to the accompanying drawings in the present application. It should be understood that the implementation manners described below in conjunction with the accompanying drawings are exemplary descriptions for explaining the technical solutions of the embodiments of the present application, and do not constitute limitations on the technical solutions of the embodiments of the present application.

[0055] Those skilled in the art of the present technology can understand that unless specifically stated, the "the" and "this" used here can also include the plural form. It should be further understood that the term "including" used in the specification of the present application means the presence of the described features, integers, steps, operations, and / or components, but does not exclude the implementation of other features, information, data, steps, operations, elements, components, and / or combinations thereof supported by the art of the present technology. The term "and / or" used here means at least one of the items defined by the term, for example, "A and / or B" can be implemented as "A", or implemented as "B", or implemented as "A and B".

[0056] To make the purpose, technical solutions, and advantages of the present application clearer, the embodiments of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0057] First, the terms related to the present application will be introduced and explained:

[0058] Flange connection: It means that two pipes, pipe fittings, or equipment, etc., are first fixed to a flange plate respectively, then a flange gasket is added between the two flange plates, and finally the two flange plates are tightened with bolts to make them closely combined.

[0059] The following will explain the related technologies:

[0060] The existing prefabricated floor steel pipe support, which is commonly used in construction, has the following basic structural form: the floor steel pipe pile columns are processed into standard segments in the factory. According to the designed spacing of the steel pipe piles, the horizontal bracings and diagonal bracings are processed in the factory. Each standard segment is equipped with a matching steel hoop, and through the steel hoop, the floor steel pipe pile columns are connected with the horizontal bracings and diagonal bracings to form an integral body.

[0061] The above floor steel pipe support has the disadvantage that it cannot achieve fully prefabricated and standardized construction. The spacing of the floor steel pipe pile columns mainly depends on the span of the pile top bearing beam at the upper end of the columns. In different projects, due to the different types and cross-sections of the upper beam bodies, the loads acting on the pile top bearing beam are different, resulting in different spacings of the floor steel pipe pile columns. The lengths of the horizontal bracings and diagonal bracings of the above prefabricated floor steel pipe support cannot be changed and are only applicable to beam bodies with specific cross-sections. If transferred to other projects, since the spacings of the steel pipe pile columns may be different, the horizontal bracings and diagonal bracings cannot be installed, and the horizontal bracings and diagonal bracings need to be reprocessed according to the project conditions, which cannot be recycled and wastes steel.

[0062] The prefabricated support and bridge construction device provided by this application aim to solve the above technical problems in the related art.

[0063] The technical solution of this application and how the technical solution of this application solves the above technical problems will be described in detail below with specific embodiments. It should be noted that the following embodiments can be referred to, learned from, or combined with each other. For the same terms, similar and similar implementation steps in different embodiments, they will not be described repeatedly.

[0117] Applying the embodiment of the present application can at least achieve the following beneficial effects:

[0118] In the embodiments of the present application, the main load-bearing components of the prefabricated support (i.e., the standard column sections of the modular columns and the modular support components) are designed as modular standard components. For example, the length and various dimensions of the standard column sections are fixed, and multiple components such as horizontal bracings and diagonal braces are fixed to form a modular support component. The length of the column adjustment section is determined by the terrain or the target load, and the other dimensions are also fixed, and all can be prefabricated and formed in the factory in advance, which is beneficial to improving the manufacturing quality. Then, at the construction site for supporting the target load (such as the pile top bearing beam), the modular standard components and the modular components with adjustable dimensions such as the column adjustment section are assembled together by a detachable connection method. The prefabricated support can achieve on-site assembly and disassembly without welding. Theoretically, no damage will be caused to the modular standard components during disassembly, and the assembly and disassembly speed is relatively fast. The modular standard components can be put into use immediately after disassembly, which can improve the reuse rate and construction turnover rate of the modular standard components.

[0119] In the embodiments of the present application, the column adjustment section is used to adjust the height of the modular column under different terrains, and the number of modular support components arranged between two adjacent modular columns can be adjusted according to the distance between the two modular columns, so as to support the two modular columns and adapt to their distance. The embodiments of the present application realize the full assembly and modularization of the modular columns, modular support components and modular column foundations of the prefabricated support, so that the prefabricated support can adapt to the construction in various situations by adjusting the height of the modular column and increasing or decreasing the number of modular support components, thereby improving the construction speed and the turnover rate of materials.
