Description

Technical Field

[0001] This invention belongs to the field of support device technology, and particularly relates to a support device for steel structure building construction. Background Technology

[0002] Supporting devices for steel structure construction are a crucial component of the building construction process. Due to the high strength, light weight, good overall rigidity, and strong resistance to deformation of steel structures, they are particularly suitable for constructing large-span, super-high, and super-heavy buildings. Therefore, supporting devices play a vital role in the construction of steel structure buildings, used to fix the structure and ensure the smooth progress of construction.

[0003] In existing technologies, when installing steel columns, the steel columns are usually lifted to the designated position by a crane, and then manually fixed in place by tightening bolts. However, most common support devices only support the steel columns during this process, but they do not help with the time-consuming and laborious bolt tightening operation, and cannot achieve rapid bolt installation. Therefore, they do not provide much help in improving the efficiency of the construction process. Summary of the Invention

[0004] The purpose of this invention is to provide a support device for steel structure construction, which aims to solve the problems mentioned in the background art.

[0005] This invention is implemented as follows: a support device for steel structure construction includes four symmetrically arranged support columns in pairs, with adjacent support columns connected to each other by detachable crossbeams. Each support column also has a clamping module at its top for fixing the assembled support columns to a steel column; it further includes:

[0006] The working module includes an annular shell that is slidably mounted vertically between assembled support columns. Each support column is equipped with a lifting module for linearly moving the annular shell vertically. A transmission ring is rotatably mounted within the annular shell, and the lifting module is equipped with a drive unit for rotating the transmission ring. An mounting ring is detachably mounted on the top of the annular shell, and a positioning post for positioning the mounting ring is located on the top wall of the annular shell. Several annular seats are arranged in a ring on the inner wall of the mounting ring, and a connecting ring is rotatably mounted on the bottom of each annular seat. A first transmission gear is mounted on the bottom of the connecting ring, and internal teeth that mesh simultaneously with each of the first transmission gears are arranged in a ring on the inner wall of the transmission ring. The first transmission gears also have bolt mounting holes for mounting fastening bolts, and an annular magnet block that magnetically attracts the fastening bolts is installed in the connecting ring.

[0007] In a further technical solution, the number of the annular seats can be any integer from 6 to 12.

[0008] A further technical solution includes a mounting base installed on the top of the support column. The mounting base is provided with an adjusting screw and a first guide rod, both of which are arranged radially along the steel column. The mounting base is provided with a threaded hole that matches the adjusting screw. A clamping plate is connected to the side of the first guide rod near the steel column, and the end of the adjusting screw near the steel column is rotatably mounted on the clamping plate.

[0009] In a further technical solution, the lifting module includes a first motor mounted on a support column, the output end of the first motor being connected to a threaded rod, a sliding seat being mounted on the threaded rod, and the sliding seat being connected to the side wall of the annular shell. A second guide rod is mounted on another support column on the same side as the support column used to mount the threaded rod, and the end of the sliding seat away from the threaded rod is slidably mounted on the second guide rod.

[0010] In a further technical solution, the drive unit includes a second motor mounted on a sliding seat, the output end of the second motor is connected to a second transmission gear, and the outer side wall of the transmission ring is provided with external teeth that mesh with the second transmission gear.

[0011] In a further technical solution, an auxiliary support module for providing auxiliary support is also provided on the outer side of each of the support columns.

[0012] In a further technical solution, the auxiliary support module includes a support rod rotatably mounted in an installation groove opened on the side wall of the support column, a support sleeve fitted at the bottom of the support rod (the inner wall of the support sleeve does not contact the outer wall of the support rod), an adjusting bolt rotatably mounted at the top of the support sleeve, and a threaded section matching the adjusting bolt provided on the support rod, and a support base rotatably mounted at the bottom of the support sleeve.

[0013] This invention provides a support device for steel structure construction. Before use, based on the number of fastening bolts required to fix the steel column in a specified working scenario, mounting rings of the corresponding specifications are installed and fixed on the annular outer shell. Simultaneously, specified fastening bolts are pre-placed in each bolt mounting hole. The fastening bolts are stably attracted to the bolt mounting holes by the annular magnets and will not fall off under gravity. During use, when the steel column is lifted and vertical, the clamping module fixes the assembled support column to the bottom of the steel column, ensuring the bottom of the support column is flush with the bottom of the steel column. After the steel column is lifted to the designated working plane, adjustments are made so that the studs at the working plane pass through the holes on the connecting flange at the bottom of the steel column. As the bottom of the steel column falls onto the working plane, the bottoms of each support column also fall onto the working plane, thus providing support to keep the steel column vertical. At this time, the lifting module is activated, driving the working module and drive unit downwards until the tops of each fastening bolt abut against the studs at the working plane. At this point, the drive unit is activated, causing the transmission ring to rotate. Through the interaction of the internal teeth and the first transmission gear, the transmission ring drives each of the first transmission gears to rotate synchronously around its own axis, continuously tightening the bolts in the bolt mounting holes onto the corresponding studs. Once all bolts are in place, the drive unit stops, and simultaneously, the lifting module moves in the opposite direction, causing the entire working module to move upwards. Because the upward pulling force on the working module is greater than the magnetic attraction between the annular magnet and the bolts, the bolts automatically detach from the annular magnet, thus completing the installation of one steel column. This device not only provides support for steel column installation but also enables rapid installation of bolts, greatly improving the stability and efficiency of steel column installation. It is easy to operate and highly adaptable. Attached Figure Description

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0023] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0024] like Figures 1-4 As shown, a support device for steel structure construction provided in one embodiment of the present invention includes four symmetrically arranged support columns 1, with adjacent support columns 1 connected to each other by a detachable crossbeam. Each support column 1 also has a clamping module 2 at its top for fixing the assembled support columns 1 to a steel column; it further includes:

[0025] The working module 3 includes an annular housing 31, which is slidably mounted vertically between the assembled support columns 1. Each support column 1 is also equipped with a lifting module 4 for linearly moving the annular housing 31 vertically. A transmission ring 32 is rotatably mounted within the annular housing 31, and the lifting module 4 is also equipped with a drive unit 5 for rotating the transmission ring 32. A mounting ring 33 is detachably mounted on the top of the annular housing 31, and a mounting ring 33 is also provided on the top wall of the annular housing 31 for... The mounting ring 33 is positioned by a positioning post 34. Several annular seats 35 are arranged in a ring on the inner wall of the mounting ring 33. A connecting ring 37 is rotatably mounted on the bottom of the annular seat 35. A first transmission gear 36 is mounted on the bottom of the connecting ring 37. The inner wall of the transmission ring 32 is arranged in a ring with internal teeth 322 that mesh with each of the first transmission gears 36. The first transmission gear 36 is also provided with bolt mounting holes 361 for mounting fastening bolts. The connecting ring 37 is also provided with an annular magnet block 38 that attracts the fastening bolts by magnetic attraction.

[0026] In this embodiment of the invention, the number of annular seats 35 can be any integer from 6 to 12. Multiple mounting rings 33 of different specifications are used as replacements, with each mounting ring 33 containing a different number of annular seats 35. This allows for the selection of different mounting rings 33 to match the corresponding number of fastening bolts according to different usage requirements. Before use, based on the number of fastening bolts required to fix the steel column in the specified working scenario (generally, for the same type of support steel column in the same steel structure building, the required number of fastening bolts is the same, so the same specification of mounting ring 33 can be used), the corresponding specification of mounting ring 33 is installed on the annular outer shell 31 and fixed. Simultaneously, the specified fastening bolts are pre-placed in each bolt mounting hole 361. The fastening bolts are stably attracted to the bolt mounting holes 361 by the annular magnet 38 and will not fall off under gravity. During use, when the steel column is lifted and in a vertical position, the clamping module 2 fixes the combined support column 1 to the bottom of the steel column, ensuring that the bottom of the support column 1 is flush with the bottom of the steel column. Once the steel column is hoisted to the designated working plane, adjustments are made so that the studs at the working plane pass through the holes in the connecting flange at the bottom of the steel column. As the bottom of the steel column falls onto the working plane, the bottoms of each support column 1 also fall onto the working plane, thus providing support to keep the steel column vertical. At this time, the lifting module 4 is activated, which drives the working module 3 and the drive unit 5 to move downwards as a whole until the tops of each fastening bolt abut against the studs at the working plane. At this time, the drive unit 5 is activated, which drives the transmission ring 32 to rotate. Under the cooperation of the internal teeth 322 and the first transmission gear 36, the transmission ring 32 drives each of the first transmission gears 36 to rotate synchronously with its own axis as the rotation center. This continuously screws the fastening bolts in the bolt mounting holes 361 onto the corresponding studs until each fastening bolt is fixed in place. Then the drive unit 5 stops, and the lifting module 4 moves in the opposite direction, driving the working module 3 to move upward as a whole. Since the upward pulling force on the working module 3 as a whole is greater than the magnetic attraction between the annular magnet block 38 and the fastening bolt, the fastening bolt will automatically disengage from the annular magnet block 38, thus completing the installation of a steel column.

[0027] like Figure 1 and 6 As shown, in a preferred embodiment of the present invention, the clamping module 2 includes a mounting base 21 installed on the top of the support column 1. The mounting base 21 is provided with an adjusting screw 23 and a first guide rod 24, and both the adjusting screw 23 and the first guide rod 24 are arranged radially along the steel column. The mounting base 21 is provided with a threaded hole that matches the adjusting screw 23. A clamping plate 22 is connected to the side of the first guide rod 24 near the steel column, and the end of the adjusting screw 23 near the steel column is rotatably mounted on the clamping plate 22.

[0028] In this embodiment of the invention, when in use, simply rotate the adjusting screw 23. The adjusting screw 23 can drive the clamping plate 22 to move closer to the steel column. The first guide rod 24 is used as a guide, so that the clamping plate 22 is finally tightly attached to the side wall of the steel column. Through the cooperation of the clamping modules 2 at the top of each support column 1, the assembled support columns 1 can be fixed to the steel column.

[0029] like Figure 1 As shown, in a preferred embodiment of the present invention, the lifting module 4 includes a first motor 41 mounted on a support column 1. The output end of the first motor 41 is connected to a threaded rod 42. A sliding seat 44 is mounted on the threaded rod 42 and is connected to the side wall of the annular shell 31. A second guide rod 43 is mounted on another support column 1 on the same side as the support column 1 used to mount the threaded rod 42. The end of the sliding seat 44 away from the threaded rod 42 is slidably mounted on the second guide rod 43.

[0030] In this embodiment of the invention, when in use, it is only necessary to start the first motor 41. The first motor 41 can drive the threaded rod 42 to rotate. Under the guidance of the second guide rod 43, the threaded rod 42 can drive the sliding seat 44 to slide along the length direction of the second guide rod 43 (i.e. the length direction of the support column 1), thereby driving the annular shell 31 to slide linearly between each support column 1 through the sliding seat 44.

[0031] like Figure 1 , Figure 3 and Figure 5 As shown, in a preferred embodiment of the present invention, the drive unit 5 includes a second motor 51 mounted on the sliding seat 44, the output end of the second motor 51 is connected to a second transmission gear 52, and external teeth 321 that mesh with the second transmission gear 52 are arranged in a ring on the outer side wall of the transmission ring 32.

[0032] In this embodiment of the invention, during use, it is only necessary to start the second motor 51. The second motor 51 can drive the second transmission gear 52 to rotate. Under the cooperation of the second transmission gear 52 and the external teeth 321, the second motor 51 can drive the transmission ring 32 to rotate synchronously. At the same time, since the drive unit 5 is mounted on the sliding seat 44, the drive unit 5 can always maintain the transmission connection with the transmission ring 32 during the linear movement of the annular shell 31, so that the transmission ring 32 can be driven to rotate at any position.

[0033] like Figure 1 and 7As shown, in a preferred embodiment of the present invention, each of the support columns 1 is further provided with an auxiliary support module 6 for auxiliary support on its outer side. The auxiliary support module 6 includes a support rod 61 rotatably mounted in an installation groove opened on the side wall of the support column 1. A support sleeve 62 is sleeved on the bottom of the support rod 61 (the inner wall of the support sleeve 62 does not contact the outer wall of the support rod 61). An adjusting bolt 64 is rotatably mounted on the top of the support sleeve 62, and a threaded section matching the adjusting bolt 64 is provided on the support rod 61. A support base 63 is rotatably mounted on the bottom of the support sleeve 62.

[0034] In this embodiment of the invention, when the support column 1 is placed on the designated plane, the adjusting bolt 64 can be turned to make the support sleeve 62 move along the axial direction of the support rod 61 until the support base 63 is fully in contact with the working plane and fully abuts against it, thereby providing auxiliary support for the support column 1. Through the cooperation of the auxiliary support modules 6 on each support column 1, the support column 1 is kept in a vertical state and has good stability.

[0035] Working Principle: Before use, based on the number of fastening bolts required to fix the steel column in the specified working scenario, install the corresponding specification mounting ring 33 onto the annular outer shell 31 and fix it. Simultaneously, pre-place the specified fastening bolts in each bolt mounting hole 361. The fastening bolts will be stably attracted to the bolt mounting holes 361 by the annular magnet 38 and will not fall off under gravity. During use, when the steel column is lifted and in a vertical position, the combined support column 1 is fixed to the bottom of the steel column by the clamping module 2, making the bottom of the support column 1 flush with the bottom of the steel column. After the steel column is lifted to the specified working plane, by adjustment, the studs at the working plane pass through the holes on the connecting flange at the bottom of the steel column. As the bottom of the steel column falls onto the working plane, the bottom of each support column 1 also falls onto the working plane, thus providing support to keep the steel column vertical. At this time, the lifting module 4 is activated, and the first motor 41 can drive the threaded rod 42 to rotate. Under the guidance of the second guide rod 43, the threaded rod 42 can drive the sliding seat 44 to slide along the length direction of the second guide rod 43 (i.e. the length direction of the support column 1), thereby driving the working module 3 and the drive unit 5 to move downward as a whole through the sliding seat 44 until the top of each fastening bolt abuts against the stud at the working plane. At this time, the drive unit 5 is activated, and the second motor 51 drives the second transmission gear 52 to rotate. Under the cooperation of the second transmission gear 52 and the external teeth 321, the second motor 51 drives the transmission ring 32 to rotate synchronously. Under the cooperation of the internal teeth 322 and the first transmission gear 36, the transmission ring 32 drives each of the first transmission gears 36 to rotate synchronously with its own axis as the rotation center, thereby continuously screwing the fastening bolts in the bolt mounting holes 361 onto the corresponding studs until each fastening bolt is fixed in place. Then the drive unit 5 stops, and at the same time the lifting module 4 moves in the opposite direction, driving the working module 3 to move upward as a whole. Since the upward pulling force on the working module 3 as a whole is greater than the magnetic attraction between the annular magnet block 38 and the fastening bolt, the fastening bolt will automatically disengage from the annular magnet block 38, thus completing the installation of a steel column.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
