Description

Technical Field

[0001] This utility model relates to the technical field of steel box girder jigs, specifically to a steel box girder assembly jig. Background Technology

[0002] The steel box girder jig is an important tooling equipment in the processing and manufacturing of steel box girders. Through the positioning and support functions of the jig, the positional accuracy of each plate unit of the steel box girder can be ensured during the assembly process, thereby improving the overall processing quality. Some adjustable jigs can also be adjusted according to the structural characteristics of different steel box girders, reducing construction difficulty and complexity, simplifying the construction process, reducing manual operation, and thus effectively improving construction efficiency.

[0003] Existing modular steel box girder jigs are mostly installed by overlapping I-beam steel frames onto columns. However, these steel frames are subjected to significant forces during use, and uneven stress can easily cause deformation, leading to dimensional deviations in the casting of the steel box girder. Therefore, this paper proposes a modular steel box girder jig to address the aforementioned technical problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model proposes a modular steel box girder jig, which solves the technical problem mentioned in the background that most existing modular steel box girder jigs are installed by overlapping I-beam steel frames onto columns. However, the steel frames are subjected to significant forces during use, and are prone to deformation due to uneven stress, leading to deviations in the casting dimensions of the steel box girder.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a steel box girder assembly frame, comprising:

[0006] The steel frame has a detachable first and second connecting seats at the bottom.

[0007] The column is arranged in multiple sets at intervals. The bottom of the column is provided with a base. The steel frame is attached to the multiple sets of columns. The side wall of the column is provided with a support frame. The support frame has an opening on one side.

[0008] The mounting post is fixedly installed at the bottom of the first connecting seat and slides longitudinally within the receiving frame; and

[0009] The reinforcing beam is arranged at an angle, with one end fixedly connected to the bottom of the mounting column and the other end fixedly connected to the second connecting seat.

[0010] Furthermore, a pin is provided at the bottom of the first connecting seat, and the pin is engaged in the cavity at the top of the column.

[0011] Furthermore, the pin and the mounting post are integrally cast with the first connecting seat.

[0012] Furthermore, multiple sets of detachable first gaskets are provided in the cavity at the top of the column, and the bottom of the pin abuts against the first gaskets.

[0013] Furthermore, the receiving frame is provided with multiple sets of detachable second gaskets, and the bottom of the mounting column abuts against the second gaskets.

[0014] Furthermore, the bottom of the receiving frame is connected to the column by reinforcing ribs.

[0015] Furthermore, the first and second connecting seats are connected to the steel frame by bolts.

[0016] Furthermore, the connection between the reinforcing beam and the mounting column and the second connecting seat is by welding.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. During assembly, the steel frame can be quickly installed by sliding the mounting columns downwards and inserting them into the receiving frame. The assembly process is convenient and quick. During use, when the steel frame is under stress, the columns support the steel frame and the steel box girder above it. The force between the two sets of columns can also be supported by the reinforcing beam and the receiving frame, thereby effectively dispersing the force applied to the steel box girder, avoiding stress concentration and deformation of the steel frame, and effectively improving the support effect of the frame.

[0019] 2. When the steel frame is used for a long time and deforms, or when the ground collapses and causes a drop in the installation height of the column, the steel frame can be leveled by adding or removing the first shim in the cavity at the top of the column or the second shim in the receiving frame. This will ensure that multiple sets of steel frames in the spaced-out frame are on the same horizontal plane, further improving the durability of the frame. Attached Figure Description

[0026] The present invention will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention. Those skilled in the art can make some non-essential improvements and adjustments to the present invention based on the above application content.

[0027] Example:

[0028] like Figure 1 , 3 As shown, this utility model provides a steel box girder assembly frame, including a steel frame 1, with a detachable first connecting seat 2 and a second connecting seat 5 at the bottom of the steel frame 1, and multiple sets of columns 7 arranged at intervals, with a base 8 at the bottom of the columns 7. The steel frame 1 is attached to the multiple sets of columns 7, and a receiving frame 10 is provided on the side wall of the columns 7. An installation column 4 is fixedly provided at the bottom of the first connecting seat 2, and the installation column 4 is longitudinally slidably locked in the receiving frame 10. It also includes multiple sets of inclined reinforcing beams 6, one end of which is fixedly connected to the bottom of the installation column 4, and the other end is fixedly connected to the second connecting seat 5.

[0029] The uprights 7 in this frame are fixed to the construction ground by the base 8. When the steel frame 1 needs to be assembled, the first connecting seat 2 and the second connecting seat 5 are first installed on the steel frame 1. The first connecting seat 2 and the second connecting seat 5 are connected to the steel frame 1 by bolts, which facilitates separate processing. Then, the mounting column 4 of the first connecting seat 2 is slid down and inserted into the receiving frame 10 to quickly complete the assembly. The reinforcing beam 6 is welded to the mounting column 4 and the second connecting seat 5. The pressure on the steel frame 1 is distributed by the contact between the reinforcing beam 6 and the bottom surface of the receiving frame 10, which prevents the steel frame 1 from deforming when it is subjected to large pressure from the steel box girder in the area between the two sets of uprights 7, thus increasing the load-bearing capacity and bending resistance of the frame. In addition, the bottom of the receiving frame 10 is connected to the uprights 7 by reinforcing ribs 12 to increase the load-bearing capacity of the receiving frame 10.

[0030] like Figure 1 , 2As shown, in this embodiment, a pin 3 is also provided at the bottom of the first connecting seat 2. The pin 3 is engaged in the top cavity of the column 7, and the pin 3 and the mounting column 4 are integrally cast with the first connecting seat 2. When the mounting column 4 is inserted into the receiving frame 10, the pin 3 is inserted into the top cavity of the column 7. Thus, the setting of the pin 3 provides further support for the steel frame 1, which can further improve the load-bearing capacity of the frame and prevent the steel frame 1 from shifting.

[0031] like Figure 2 As shown, in this embodiment, multiple sets of detachable first gaskets 9 are provided in the cavity at the top of the column 7, and the bottom of the pin column 3 abuts against the first gaskets 9. Multiple sets of detachable second gaskets 11 are provided in the receiving frame 10, and the bottom of the mounting column 4 abuts against the second gaskets 11. When the steel frame 1 deforms or the column 7 shifts downward due to ground subsidence, the steel frame 1 can be leveled by adding or removing the first gaskets 9 or the second gaskets 11 to improve construction accuracy.

[0032] The specific usage and beneficial effects of this utility model are as follows:

[0033] During assembly, the steel frame 1 can be quickly installed by sliding the mounting column 4 downwards and inserting it into the receiving frame 10. The assembly process is convenient and quick. During use, when the steel frame 1 is under stress, the column 7 supports the steel frame 1 and the steel box girder above it. The force between the two sets of column 7 can also be supported by the reinforcing beam 6 and the receiving frame 10, thereby effectively dispersing the force applied to the steel box girder, avoiding stress concentration and deformation of the steel frame 1, and effectively improving the support effect of the frame.

[0034] When the steel frame 1 deforms after long-term use, or when the ground collapses and causes a drop in the installation height of the column 7, the steel frame 1 can be leveled by adding or removing the first shim 9 in the top cavity of the column 7 or the second shim 11 in the receiving frame 10. This ensures that multiple sets of steel frames 1 in the multiple sets of spaced-apart frames are on the same horizontal plane, further improving the durability of the frame.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above. Modifications or improvements can be made to this utility model, which is obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of this utility model fall within the scope of protection claimed by this utility model.
