[0002] During the hoisting and welding process of the steel box girder of a bridge, when connecting and fixing the steel box girder in the air, it is usually necessary to set up a temporary support frame to support the steel box girder. When the existing temporary support frame is built, usually after ground leveling and hardening and other basic treatment measures are carried out at the position where the temporary support frame is set up, then the temporary support frame platform is built on the spot, and shim steel plates or shim blocks are placed on the platform to adjust the shim elevation of the steel box girder. The steel box girder is placed on the shim blocks for connection, and the temporary support frame is removed after the connection is completed.

[0003] However, when the position where the temporary support frame is set up is inconvenient for personnel and mechanical equipment to reach, and the terrain is undulating and it is inconvenient to carry out ground hardening and leveling treatment, at this time, when using the conventional method to build the temporary support frame, the building speed will be very slow, seriously affecting the construction progress. Summary of the Invention

By providing a large steel pipe column and a small steel pipe column, the support height between the two can be adjusted, so that the temporary support device can adapt to the undulating terrain, and there is no need to carry out basic treatment such as ground leveling and hardening, realizing the rapid construction of the temporary support device.

[0005] The technical solution of the utility model: A temporary support device that can conveniently adjust the elevation to adapt to complex terrain conditions, including a rectangular operation steel plate, the bottom of the rectangular operation steel plate is supported and fixed on 2 parallel horizontal support I-beams, the bottom ends of each horizontal support I-beam are fixedly supported on 2 vertically arranged large steel pipe columns, a small steel pipe column is movably sleeved inside the lower end of the large steel pipe column, a plurality of corresponding through holes are provided on the lower end of the large steel pipe column and the small steel pipe column, and the pin shaft passes through the through holes on the large steel pipe column and the small steel pipe column to fix the two together. A bridge sand cylinder temporary support is also arranged on the rectangular operation steel plate directly above the 2 horizontal support I-beams.

[0006] In the foregoing temporary support device that can conveniently adjust the elevation to adapt to complex terrain conditions, the inner hole at the lower end of the small steel pipe column is a threaded hole, and the upper end of the T-shaped fine-tuning shim block is screwed into the threaded hole of the small steel pipe column.

[0007] In the aforementioned temporary support device that can conveniently adjust the elevation to adapt to complex terrain conditions, an installation block is fixed on the top surface of the large steel pipe column. The fixing bolts pass through the installation block and the lower flange of the transverse support I-beam and then fix the two together. The fixing bolts pass through the rectangular operation steel plate and the upper flange of the transverse support I-beam and then fix the two together.

[0008] In the aforementioned temporary support device that can conveniently adjust the elevation to adapt to complex terrain conditions, 2 marking lines that are directly opposite to the position of the transverse support I-beam are arranged on the surface of the rectangular operation steel plate.

[0009] In the aforementioned temporary support device that can conveniently adjust the elevation to adapt to complex terrain conditions, 2 large steel pipe columns on the same side are fixedly connected together through connecting members.

[0013] The beneficial effects of the present utility model: Compared with the prior art, the present utility model has the following advantages:

[0014] The temporary support device of the present utility model can adjust the elevation of the entire support column by inserting the pin shafts into the insertion holes at different positions of the large steel pipe column and the small steel pipe column. At the same time, the elevation of the support column is finely adjusted by combining the fine-tuning support pads, so that the temporary support device can adapt to the undulating terrain. The process of ground leveling and hardening can be omitted during the erection process of the temporary support device, which improves the erection speed of the temporary support device under complex terrain conditions and ensures the construction progress.

[0015] 2 transverse support I-beams are provided, and a bridge sand cylinder temporary support is arranged on the rectangular operation steel plate directly above it to realize the support and elevation adjustment of the bridge steel box girder.

Detailed Description of the Embodiment

[0023] The following further describes the present utility model in conjunction with the drawings and embodiments, but it shall not be used as a basis for limiting the present utility model.

[0024] Embodiment of the present utility model: A temporary support device capable of conveniently adjusting the elevation to adapt to complex terrain conditions, as Figures 1-4As shown in the figure, it includes a rectangular operation steel plate 1. The bottom of the rectangular operation steel plate 1 is supported and fixed on two horizontally arranged transverse support I-beams 2. The bottom ends of each transverse support I-beam 2 are fixedly supported on two vertically arranged large steel pipe columns 3. The four large steel pipe columns 3 form a rectangular distribution structure. A small steel pipe column 4 is movably sleeved inside the lower end of each large steel pipe column 3. A plurality of corresponding penetration holes 5 are arranged along the height direction on each large steel pipe column 3 and each small steel pipe column 4. A large steel pipe column 3 and a small steel pipe column 4 are combined together to form a support column. A pin shaft 6 passes through the penetration holes 5 on the large steel pipe column 3 and the small steel pipe column 4 to fix the large steel pipe column 3 and the small steel pipe column 4 together. A bridge sand cylinder temporary support 13 is also arranged on the rectangular operation steel plate 1 directly above the two transverse support I-beams 2.

[0025] When the temporary support device of the present utility model is erected, according to the terrain conditions at the erection position, the heights of the four support columns are measured. Since the length of the large steel pipe column 3 is fixed, at this time, the length of the small steel pipe column 4 extending into the large steel pipe column 3 is adjusted to match the height of the corresponding support column, and the large steel pipe column 3 and the small steel pipe column 4 are fixed by the pin shaft 6. After assembling four support columns matching the terrain, the transverse support I-beams 2 and the rectangular operation steel plate 1 can be installed on their top surfaces, thus forming the entire temporary support device.

[0026] Since the penetration holes 5 on the large steel pipe column 3 and the small steel pipe column 4 are arranged at a certain interval, when the large steel pipe column 3 and the small steel pipe column 4 are fixed together by the pin shaft 6, it cannot be guaranteed that the height of the obtained support column just coincides with the terrain. For example, the required height of the support column is 5070 mm, and the interval of one penetration hole 5 for the small steel pipe column 4 to slide inside the large steel pipe column 3 is 50 mm. When the small steel pipe column 4 and the large steel pipe column 3 are fixed together, the height of the support column that can be obtained is 5050 mm. If the small steel pipe column 4 is moved downward by one displacement of the penetration hole 5, the obtained height is 5100 mm, which is higher than the required height. At this time, the actual height of 5050 mm obtained is 20 mm different from the required height of 5070 mm. In this case, a cushion block with a thickness of 20 mm needs to be padded at the bottom of the small steel pipe column 4 to ensure that the rectangular operation steel plate 1 of the finally obtained temporary support device is completely horizontal.

[0027] During use, the temporary bridge sand barrel support 13 can be placed on the rectangular operation steel plate 1 directly above the transverse support I-beam 2. According to the specific situation of the bridge steel box girder, the setting position of the temporary bridge sand barrel support 13 can be adjusted arbitrarily along the length direction of the transverse support I-beam 2. Generally, two temporary bridge sand barrel supports 13 are correspondingly arranged directly above each transverse support I-beam 2, and the bridge steel box girder can be supported by the temporary bridge sand barrel supports 13. By adjusting the amount of sand filled in the temporary bridge sand barrel support 13, the bridge steel box girder can be adjusted to the required elevation. The temporary bridge sand barrel support 13 is a conventional component in this field, and its specific structure and usage method are well-known technologies in this field, so the specific structure and usage method will not be elaborated here.

[0028] The reason why the temporary bridge sand barrel support 13 is set on the rectangular operation steel plate 1 directly above the transverse support I-beam 2 is that if the temporary bridge sand barrel support 13 and the transverse support I-beam 2 are misaligned, a structure similar to a seesaw will be formed among the rectangular operation steel plate 1, the transverse support I-beam 2, and the bridge steel box girder. Then, during the downward transmission of the gravity of the bridge steel box girder, the rectangular operation steel plate 1 will be directly deformed under pressure, resulting in the entire structure being unable to support the bridge steel box girder. When the temporary bridge sand barrel support 13 is set on the rectangular operation steel plate 1 directly above the transverse support I-beam 2, although the rectangular operation steel plate 1 is also under pressure, the gravity of the bridge steel box girder is vertically downward and directly transmitted to the transverse support I-beam 2 through the rectangular operation steel plate 1, and the rectangular operation steel plate 1 will not be bent due to pressure.

[0029] The rectangular operation steel plate 1 is mainly set to facilitate the operators to stand on it for construction operations. The entire structure mainly relies on the support columns composed of the temporary bridge sand barrel support 13, the transverse support I-beam 2, the large steel pipe column 3, and the small steel pipe column 4 to bear pressure.

[0030] The inner hole at the lower end of the small steel pipe column 4 is a threaded hole, and the upper end cylinder of the fine-tuning support pad 7 with a T-shaped structure is provided with an external thread. The upper end cylinder of the fine-tuning support pad 7 can be screwed into the threaded hole of the small steel pipe column 4 by thread. When the height of the combined support column is less than the displacement of one penetration hole 5 from the required height, the height of the support column can be adjusted to the required height by rotating the fine-tuning support pad 7, and there is no need to place a pad at the bottom of the small steel pipe column 4 anymore.

[0031] An installation block 12 is welded and fixed to the top surface of the large steel pipe column 3. After the fixing bolt 8 passes through the through holes in the installation block 12 and the lower flange of the transverse support I-beam 2, the large steel pipe column 3 and the transverse support I-beam 2 can be fixed together. The fixing bolt 8 passes through the rectangular operation steel plate 1 and the upper flange of the transverse support I-beam 2 to fix the two together. This structure can achieve the rapid installation and disassembly between components, and hardly damage the component body during the installation and disassembly process, improving the service life of the components.

[0032] Two marking lines 14 are arranged on the surface of the rectangular operation steel plate 1 and are aligned with the position of the transverse support I-beam 2. Each marking line 14 is composed of two lines, corresponding to the two long sides of the transverse support I-beam 2 respectively. The arrangement of the marking lines 14 can quickly know the setting range of the bridge sand barrel temporary support 13, ensuring that the bridge sand barrel temporary support 13 is placed directly above the transverse support I-beam 2.

[0033] Two large steel pipe columns 3 on the same side are fixedly connected together through a connecting member 9. The four large steel pipe columns 3 are connected and fixed together through the connecting member 9, thereby improving the stability of the overall structure and better supporting the bridge steel box girder.

[0034] Connecting plates A10 are welded and fixedly connected to both ends of the connecting member 9. Connecting plates B11 are welded and fixedly connected to the outer wall of the large steel pipe column 3. After the fixing bolt 8 passes through the connecting plates A10 and B11, the large steel pipe column 3 and the connecting member 9 are fixedly connected together. This structure is also for the rapid installation and disassembly between components.

[0035] Two large steel pipe columns 3 on the same side are fixedly connected together through two parallel connecting members 9 arranged horizontally, making the overall structure more stable. The horizontally arranged connecting member 9 and the vertically arranged connecting member 9 are arranged vertically offset. Correspondingly, the connecting plates B11 on the outer wall of the large steel pipe column 3 connected to the horizontally arranged connecting member 9 and the connecting plates B11 connected to the vertically arranged connecting member 9 are also arranged vertically offset. If not offset, the connecting plates B11 connected horizontally and vertically will intersect with each other, forming an interfering situation, which is not conducive to construction operations.

[0036] Each large steel pipe column 3 is fixedly connected to the small steel pipe column 4 through two pin shafts 6. The entire temporary support device transmits the pressure borne by the large steel pipe column 3 to the small steel pipe column 4 through the pin shafts 6. The pin shafts 6 bear the downward shearing action of the large steel pipe column 3. Once the pin shafts 6 are sheared and broken, the entire support structure will collapse. Therefore, two pin shafts 6 are provided to increase the guarantee and improve the stability of the support column after connection.
