Description

Technical Field

[0001] This utility model relates to the technical field of steel pedestals for manufacturing steel box girders, and specifically to a movable steel pedestal structure. Background Technology

[0002] In the early stages of box girder prefabrication, concrete fixed platforms were often used. However, concrete fixed platforms suffer from long curing periods and low site utilization rates, especially in cross-river and cross-valley bridge projects, where temporary platforms need to be repeatedly dismantled and rebuilt, leading to increased costs. With the advent of steel platforms, they have gradually replaced concrete platforms. Steel platforms not only shorten the prefabrication cycle but also allow for relocation and multiple disassembly and assembly for reuse, reducing manufacturing costs. However, existing steel platforms still have certain drawbacks. Their installation often requires welded support frames, which, while shortening the construction period compared to concrete platforms, is time-consuming and labor-intensive. Dismantling is also time-consuming and labor-intensive. If bolt fixing is used, steel platforms are unstable and prone to deformation. Therefore, it is necessary to design a movable steel platform to solve the problems of time-consuming and labor-intensive disassembly and assembly, as well as stability issues. Utility Model Content

[0003] To address the aforementioned problems, the main objective of this utility model is to provide a movable steel platform that solves the problem of time-consuming and laborious assembly and disassembly of the steel platform, while also improving the overall robustness and stability of the steel platform.

[0004] To achieve the above objectives, this utility model provides a movable steel platform, comprising several steel platform units. Each steel platform unit includes a support column, a crossbeam, a load-bearing platform, and a reinforcing steel beam. There are two support columns and two reinforcing steel beams. The reinforcing steel beams are located on the lower end face of the load-bearing platform and on the outer side of the support column. The two ends of the support column and the reinforcing steel beam are aligned along the length direction. The load-bearing platform has the same length as the support column or the reinforcing steel beam. The load-bearing platform is fixed to the support column and the reinforcing steel beam in a staggered manner along the length direction.

[0005] Preferably, the support column includes an upper support beam, a lower support beam, and a support plate, with the load-bearing platform fixed on the top surface of the upper support beam.

[0006] Preferably, there are multiple crossbeams, which are evenly and vertically arranged between the support plates of the two support columns.

[0007] Preferably, the reinforcing steel beam includes an upper steel plate, a side steel plate, and a lower steel plate. The upper end of the upper steel plate is fixedly connected to the lower end face of the bearing platform. The side steel plate is vertically arranged between the upper steel plate and the lower steel plate. The inner side of the lower steel plate is fixedly connected to the outer side of the support plate.

[0008] Preferably, the reinforcing steel beam further includes two limiting plates, which are fixed at both ends of the outer side of the side steel plate, and the two limiting plates are perpendicular to the upper steel plate and the lower steel plate.

[0009] Preferably, the limiting plate is provided with positioning holes, and fixing bolts are inserted into the positioning holes of the limiting plates of adjacent steel base units.

[0010] Preferably, the crossbeam is an I-beam and the load-bearing platform is a steel plate structure.

[0011] Preferably, in adjacent steel pedestal units, one end of the bearing platform of one steel pedestal unit is connected to the protruding end of the support column or reinforcing steel beam of another steel pedestal unit, and the protruding bearing platform is erected on the protruding support column and reinforcing steel beam.

[0012] The beneficial effects of this utility model through the above technical solution include:

[0013] (1) The movable steel platform of this utility model is assembled from several steel platform units. The steel platform units are connected by the bearing platform of one steel platform unit being erected on the support column and reinforcing steel beam of another steel platform unit. This not only improves the stability of the steel platform, but also realizes the connection between the steel platform units.

[0014] (2) In addition, the adjacent steel base units of the movable steel base of this utility model are fixed by fixing bolts in the adjacent limiting plates to prevent misalignment in the left and right directions and further improve the overall stability of the steel base.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] like Figure 1 The diagram shows the overall structure of the movable steel platform of this utility model. The steel platform is assembled from several steel platform units 1. As shown in the diagram, the several steel platform units 1 are connected adjacent to each other in a straight line. Please refer to [link to diagram]. Figure 2 and Figure 3 The figures shown are structural schematic diagrams of the steel pedestal unit 1 of this utility model from different angles. The steel pedestal unit 1 includes support columns 10, crossbeams 20, and a bearing platform 30. There are two support columns 10, which are arranged parallel to each other at a certain distance. The bearing platform 30 is a steel plate structure and is located above the support columns 10. Specifically, the support columns 10 have an upper support beam 11, a lower support beam 12, and a support plate 13. The support plate 13 is arranged between the upper support beam 11 and the lower support beam 12. The bearing platform 30 is fixed to the top surface of the upper support beam 11. There are multiple crossbeams 20, which are I-beams. The crossbeams 20 are evenly and vertically arranged between the support plates 13 of the two support columns 10, and provide lateral support to the support columns 10.

[0024] Please continue reading. Figure 2 and Figure 3 As shown, the steel pedestal unit 1 of this utility model is also provided with reinforcing steel beams 40. There are two reinforcing steel beams 40. The reinforcing steel beams 40 are located on the lower end face of the bearing platform 30, and the two reinforcing steel beams 40 are respectively located on the outer side of the support column 10. The reinforcing steel beams 40 are provided with an upper steel plate 41, a side steel plate 42 and a lower steel plate 43. The upper end of the upper steel plate 41 is fixedly connected to the lower end face of the bearing platform 30. The side steel plate 42 is vertically arranged between the upper steel plate 41 and the lower steel plate 43. The inner side of the lower steel plate 43 is fixedly connected to the outer side of the support plate 13, which can be fixedly connected by welding.

[0025] In this invention, the supporting column 10 and the reinforcing steel beam 40 are aligned at both ends along their length. The bearing platform 30 has the same length as the supporting column 10 or the reinforcing steel beam 40, but it is fixed to the supporting column 10 and the reinforcing steel beam 40 in a staggered manner along its length. In other words, one end of the bearing platform 30 protrudes, completely covering that end of the supporting column 10 and the reinforcing steel beam 40, while the other end is not completely covered, with a portion of the structure exposed. Since the length of the bearing platform 30 is the same as the length of the supporting column 10 and / or the reinforcing steel beam 40, the length of the protruding portion of the bearing platform 30 is the same as the length of the protruding portion of the other end of the supporting column 10 or the reinforcing steel beam 40. Therefore, as... Figure 4 As shown, in adjacent steel pedestal units 1, one end of the bearing platform 30 of one steel pedestal unit 1 is connected to the protruding end of the support column 10 or the reinforcing steel beam 40 of the other steel pedestal unit 1. The protruding bearing platform 30 is erected on the protruding support column 10 and the reinforcing steel beam 40, which not only improves the stability of the steel pedestal but also achieves a stable connection between the steel pedestal units 1. Compared with the simple welding method or other bolt connection method in the prior art, the bearing platforms 30 of adjacent steel pedestal units 1 of this utility model are mutually erected, which can form an integral structure of each unit part and support it as a whole when bearing the box girder.

[0026] Please refer to the following: Figures 2-4 As shown, the reinforcing steel beam 40 of this utility model is also provided with two limiting plates 44. The two limiting plates 44 are respectively fixed at both ends of the outer side of the side steel plate 42, and the two limiting plates 44 are perpendicular to the upper steel plate 41 and the lower steel plate 43. The limiting plates 44 are provided with positioning holes 441. Fixing bolts 45 are inserted into the positioning holes 441 of the adjacent limiting plates 44 of the adjacent steel platform units 1. The adjacent steel platform units 1 of the movable steel platform of this utility model are also fixed by fixing bolts 45 in the adjacent limiting plates 44 to prevent misalignment in the left and right directions, further improving the overall stability of the steel platform. Moreover, the bolt fixing makes installation convenient and disassembly more convenient. Compared with the welding method, it does not affect the service life of the entire steel platform.

[0027] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
