Technical Field

[0001] This utility model relates to the field of steel structure construction equipment technology, and more specifically, to a segmented steel beam installation support device. Background Technology

[0002] During construction, when encountering cantilever beams with large cantilever spans or segmented steel beam installations, the conventional approach is to use standard section lattice supports, with unloading employing a synchronous cyclic cutting method. This method has numerous drawbacks:

[0003] 1) Lattice-type supports have a large overall cross-section and are constrained by construction space;

[0004] 2) There are many supporting members, resulting in a large amount of construction work. When the standard section does not match the actual height, it is difficult to make modifications.

[0005] 3) The control of the arch elevation is too rough, and it is impossible to adjust the elevation of the support surface according to the actual situation.

[0006] 4) Unloading is dangerous, the amount of cutting each time is difficult to control, and it is easy to damage the parent material.

[0007] There is an urgent need for a simple steel beam installation support device that allows for flexible and precise elevation adjustment. Utility Model Content

[0008] In view of the above problems, the purpose of this utility model is to provide a segmented steel beam installation support device, which is used to support the segmented steel pipe or cantilever beam below. The support height can be precisely adjusted, the support is stable, the disassembly and assembly are simple, and it can be reused.

[0009] This utility model provides a segmented steel beam installation support device, including a support rod and a height adjustment component disposed on the upper part of the support rod, wherein,

[0010] The support rod includes a steel column and a base plate disposed at the bottom of the steel column;

[0011] The height adjustment component includes a horizontal pad beam disposed at the top of the steel column. The upper surface of the pad beam is flat, and at least two sleeves are disposed in the middle of the upper surface of the pad beam. The sleeves are provided with internal threads and bolts are screwed in.

[0012] The support rod is supported on the ground, and the height adjustment component is supported below the segmented steel beam to be installed.

[0014] One option is to have four sleeves, all of which are set on the upper flange of the I-beam and distributed at the four corners of the square. The center point of the square and the center point of the upper flange are on the same vertical line. The bolts in the four sleeves are adjusted to the same height, and the bolts are supported below the segmented steel beam.

[0015] One option is that the bolt is a hexagonal bolt with a diameter of not less than 12cm.

[0016] One option is to provide two vertical limiting plates along the centerline of the upper wing plate, the two limiting plates being symmetrical about the centerline of the upper wing plate in the width direction, and the distance between the two limiting plates being equal to the width of the segmented steel beam.

[0017] One option is that the limiting plate includes a rectangular plate, one wide side of which is welded to the center line of the upper wing plate along its length, and the other wide side of which is welded to the long base of a right-angled trapezoidal plate, wherein the length of the long base of the right-angled trapezoidal plate is the same as the width of the rectangular plate.

[0021] One option is to provide a through hole in the upper half of the steel column, with the central axis of the through hole parallel to the segmented steel beam, and a connecting rod passing through the through hole in each steel column, the connecting rod being welded and fixed to the through hole.

[0022] As described above, the segmented steel beam installation support device provided by this utility model includes a support rod and a height adjustment component located on the upper part of the support rod.

[0036] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0037] like Figures 1-4As shown, the segmented steel beam installation support device proposed in this embodiment can be used to support the segmented steel beams or cantilever beams of large-span steel beams, facilitating the installation between steel beams. It can also be used to support other taller crossbeams, facilitating the installation between crossbeams.

[0038] The support device for this segmented steel beam 7 includes a support rod 1 and a height adjustment component 2 located on the upper part of the support rod 1. The support rod 1 is used to support the height adjustment component 2 to a certain height. The height adjustment component 2 is used to fine-tune the support height of this support device, so that the support height strictly conforms to the design elevation of the segmented steel beam 7, while ensuring the accuracy of the camber value.

[0039] For stability, the support rod 1 includes a steel column 11 and a base plate 12 at the bottom of the steel column 11. The base plate 12 is in contact with the ground, which allows the steel column 11 to be stably supported. The height of the steel column 11 can be determined according to the construction conditions.

[0040] For precise adjustment, the height adjustment component 2 may include a horizontal pad beam 21 set on the top of the steel column 11. The upper surface of the pad beam 21 is flat. The pad beam 21 is horizontal above the steel column 11, perpendicular to the supporting segmented crossbeam, and its length is slightly longer than the width of the segmented crossbeam. It is used to stably support the upper adjustment device and the segmented crossbeam.

[0041] The adjustment device can be at least two sleeves 22 located in the middle of the upper surface of the support beam 21. Each sleeve 22 has internal threads and is screwed with a bolt 23. The sleeves 22 are evenly distributed in the middle of the upper surface of the support beam 21, and the area formed by the sleeves 22 can stably support the lower surface of the segmented steel beam 7. Adjusting the bolts 23 in the sleeves 22 allows for precise fine-tuning of the support height to flexibly and accurately adapt to the elevation of the segmented steel beam 7, while ensuring the camber value.

[0042] During construction, the support rod 1 is placed below the point that needs support and firmly supported on the ground. The height adjustment component 2 is then finely adjusted to reach the required elevation so that it can be supported below the segmented steel beam 7 to be installed.

[0043] In one specific embodiment of this utility model, the pad beam 21 may include an I-beam with a length greater than the width of the segmented steel beam 7. The steel column 11 is welded to the middle of the lower flange of the I-beam, and the I-beam is perpendicular to the segmented steel beam 7. Using an I-beam as the pad beam 21 results in a sturdy structure, with both the upper and lower flanges being flat. An I-beam with a larger flange width can be selected, allowing the flange width to cover the upper end face of the steel column 11, ensuring a stable and secure weld between the steel column 11 and the I-beam.

[0044] In a specific embodiment of this utility model, in order to further balance and support the segmented steel beam, the number of sleeves 22 is four. The four sleeves 22 are all set on the upper flange of the I-beam and distributed at the four corners of a square to form a square array. The center point of the square and the center point of the upper flange are on the same vertical line. The bolts 23 in the four sleeves 22 are adjusted to the same height, and the bolts 23 are supported below the segmented steel beam 7.

[0045] The four sleeve bolts are evenly welded to the middle of the upper flange. The bolts 23 in each sleeve 22 are screwed to the elevation. The four bolts 23 can more stably support the segmented steel beam 7.

[0046] In one specific embodiment of this utility model, the bolt 23 is a hexagonal bolt 23 with a diameter of not less than 12cm. Bolts 23 with an M12 or larger diameter provide more stable and powerful support, and the nuts of the hexagonal bolts 23 can increase the stability of the support.

[0047] In one specific embodiment of this utility model, in order to further stabilize the support, two vertical limiting plates 24 are provided along the centerline of the length direction of the upper wing plate. The two limiting plates 24 are symmetrical about the centerline of the width direction of the upper wing plate, and the distance between the two limiting plates 24 is equal to the width of the segmented steel beam 7.

[0048] After the segmented steel beam 7 is supported on the four bolts 23, the two limiting plates 24 can block the two sides of the segmented steel beam 7 to make it more stable, and at the same time control the accurate positioning of the axis of the segmented steel beam 7, so that the horizontal position of the segmented steel beam 7 is correct.

[0049] In one specific embodiment of this utility model, the limiting plate 24 includes a rectangular plate 241. One wide side of the rectangular plate 241 is welded to the center line of the upper wing plate along its length. The other wide side of the rectangular plate 241 is welded to the long base side of the right-angled trapezoidal plate 242. The length of the long base side of the right-angled trapezoidal plate 242 is the same as the width of the rectangular plate 241. The lower part of the opposite sides of the two limiting plates 24 is a straight edge, and the upper part is a sloping edge. The sloping edge facilitates the placement of the segmented steel beam 7 between the two limiting plates 24, providing convenient support.

[0050] In one specific embodiment of this utility model, in order to ensure the firmness of the height adjustment component 2, a reinforcing plate 25 is connected between the two flanges of the I-beam, and a stiffening plate 26 is connected between the steel column 11 and the adjacent flange.

[0051] Two vertical reinforcing plates 25 can be evenly welded between one side of the waist plate and the two flanges, and two more vertical reinforcing plates 25 can be evenly welded between the other side of the waist plate and the two flanges to strengthen the I-beam's stability. Four stiffening plates 26 can be evenly welded between the steel column 11 and the lower flange to strengthen the connection between the steel column 11 and the I-beam and to enhance the pressure resistance of the height adjustment component 2.

[0052] In one specific embodiment of this utility model, the steel column 11 can be a square steel column or a round steel column, and the base plate 12 can be a square steel plate. Through holes 13 are provided at the four corners of the square steel plate, and the base plate 12 can be fixed to the ground by bolts passing through the through holes 13.

[0053] In one specific embodiment of this utility model, to make the support column more stable, two ear plates 3 are evenly arranged around the upper half of the steel column 11. Guy ropes 4 are connected between the ear plates 3 and the ground, and the plane containing the two guy ropes 4 is perpendicular to the segmented steel beam 7. The guy ropes 4 can be steel wire ropes, with one end connected to the ear plate 3 and the other end connected to a pre-embedded hanging ring on the ground. Each support column also has its lateral stability enhanced by the guy ropes 4.

[0054] In a specific embodiment of this utility model, in order to make the support more stable, each support rod 1 is connected as a whole. A through hole 5 can be provided in the upper half of the support rod 1. The central axis of the through hole 5 is parallel to the segmented steel beam 7. A connecting rod 6 is inserted into the through hole 5 of each support rod 1. The connecting rod 6 is welded and fixed to the through hole 5.

[0055] The supporting devices at each point are connected into a whole by connecting rods 6 passing through each support rod 1. The two ends of the connecting rods 6 can also be welded to the vertical steel columns 8 on both sides of the crossbeam, ensuring the overall stability of the support system. The connecting rods 6 can be made of small-diameter steel pipes.

[0056] During construction, this support device can be installed at the locations requiring support according to the specific construction conditions, and then each support rod 1 is connected via connecting rod 6. In this embodiment, after the vertical steel columns 8 on both sides of the crossbeam are installed, this support device is installed below each section of steel beam 7 where support is required. Guy ropes 4 are strung, connecting rods 6 are installed, and the height of bolts 23 is adjusted to support the section of steel beam 7 sequentially. In this embodiment, the specific support points can be set up as follows: one end of the first section of steel beam 7 is temporarily connected to the vertical steel column 8 via a support plate, and the other end is supported by this support device; one end of the second section of steel beam 7 is temporarily connected to the first section of steel beam 7 via a support plate, and the other end is supported by this support device, and so on, connecting and supporting the section of steel beam 7 sequentially. The support device makes the installation between adjacent section of steel beam 7 convenient, stable, and precise, and allows for re-measuring of elevations. Precise positioning is achieved by adjusting the elevation of bolts 23. After the section of steel beam 7 is installed, the support device is removed after lowering the height of bolts 23.
