Description

Technical Field

[0001] This utility model belongs to the field of marine engineering technology, and in particular relates to a device for assembling the side stiffening plates of an I-beam. Background Technology

[0002] The construction of offshore oil platforms and LNG modules involves a large number of stiffening plate assembly operations. Before assembling the stiffening plates, positioning plates need to be welded to multiple locations on the stiffening plates. The positioning plates are then welded to the I-beams to complete the assembly work between the stiffening plates and the I-beams. Finally, the stiffening plates are welded to the I-beams, and the positioning plates are cut.

[0003] According to quality requirements, the welding position of the positioning plate needs to be ground and preheated, and there are requirements for the size and shape of the positioning plate. In the stiffener assembly project, connecting and fixing the stiffeners with positioning plates not only wastes manpower and resources, but also increases construction time. Furthermore, it is not convenient to make fine adjustments to the position of the stiffeners after the positioning plate is connected to the I-beam.

[0004] Therefore, there is an urgent need to design a device for assembling the side stiffeners of I-beams to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a device for assembling the side stiffener plates of an I-beam, which has the advantages of micro-adjustment function, improving assembly quality and efficiency, and solving the problems in the prior art where it is inconvenient to fine-tune the position of the stiffener plates after the positioning plate is connected to the I-beam and the stiffener plates need to be fixed by welding through the positioning plate.

[0006] To achieve the above objectives, the specific technical solution of the I-beam side stiffener assembly device of this utility model is as follows: A device for assembling side stiffeners of an I-beam comprises a first snap-fit ​​structure symmetrically arranged on the upper flange of the I-beam and a second snap-fit ​​structure on the lower flange of the I-beam. The first and second snap-fit ​​structures fix the stiffeners to the side of the I-beam. A first angle steel and a second angle steel are connected at intervals on the first snap-fit ​​structure, and a third angle steel and a fourth angle steel are connected at intervals on the second snap-fit ​​structure. By rotating the adjusting bolts on the first and third angle steels respectively, the stiffeners abut against the springs of the second and fourth angle steels and move along a first or second direction, so that the stiffeners can be assembled and welded to the I-beam.

[0007] Furthermore, the adjusting bolts screwed onto the first and third angle steels are aligned horizontally with the springs connected to the second and fourth angle steels, respectively.

[0008] Furthermore, the first snap-fit ​​structure includes a first connecting plate and a second connecting plate. The second connecting plate is vertically connected to the first connecting plate. A first shear jack is connected to the center of the first connecting plate. A first angle steel and a second angle steel are connected at intervals on the side of the second connecting plate away from the first connecting plate. The first shear jack abuts against the upper flange of the I-beam, so that both the first angle steel and the second angle steel abut against the side of the upper flange of the I-beam away from the first shear jack.

[0009] Furthermore, a first notch is formed between the first angle steel and the second angle steel so that the stiffening plate abuts against the upper flange of the I-beam along the first notch.

[0010] Furthermore, by rotating the adjusting bolt screwed onto the first angle steel clockwise, one end of the rib plate moves in the first notch along the first direction. By rotating the adjusting bolt screwed onto the first angle steel counterclockwise, the spring on the second angle steel drives one end of the rib plate to move in the first notch along the second direction.

[0011] Furthermore, the second snap-fit ​​structure includes a third connecting plate and a fourth connecting plate. The fourth connecting plate is vertically connected to the third connecting plate. A second shear jack is connected to the center of the third connecting plate. A third angle steel and a fourth angle steel are connected at intervals on the side of the fourth connecting plate away from the third connecting plate. The second shear jack abuts against the lower flange of the I-beam, so that both the third angle steel and the fourth angle steel abut against the side of the lower flange of the I-beam away from the second shear jack.

[0012] Furthermore, a second notch is formed between the third and fourth angle steels so that the end of the stiffening plate away from the upper flange of the I-beam abuts against the lower flange of the I-beam along the second notch.

[0013] Furthermore, by rotating the adjusting bolt screwed on the third angle steel clockwise, the end of the stiffening plate away from the upper flange of the I-beam moves in the second notch along the first direction. By rotating the adjusting bolt screwed on the third angle steel counterclockwise, the spring on the fourth angle steel drives the end of the stiffening plate away from the upper flange of the I-beam to move in the second notch along the second direction.

[0014] The I-beam side stiffener assembly device of this utility model has the following advantages: The first clamping structure is fixed to the upper flange of the I-beam using a first shear jack, and the second clamping structure is fixed to the lower flange of the I-beam using a second shear jack. The two ends of the stiffening plate are fixed between the first and second clamping structures respectively using adjusting bolts and springs. Rotating the adjusting bolts changes the fixed position of the stiffening plate on the side of the I-beam, thus enabling the assembly and welding of the stiffening plate to the I-beam. This application not only eliminates the need for welding the positioning plate but also provides a micro-adjustment function, improving assembly quality and efficiency while reducing the labor intensity of workers and construction costs.

For example, in the claims, any of the claimed embodiments can be used in any combination.

[0019] The following is a reference to the appendix. Figure 1 To be continued Figure 2 This invention describes the assembly device for the side stiffening plates of an I-beam.

[0020] like Figure 1 As shown, the I-beam side stiffener assembly device of this utility model consists of a first snap-fit ​​structure 1 symmetrically arranged on the upper flange of the I-beam and a second snap-fit ​​structure 2 on the lower flange of the I-beam. The stiffener is fixed to the side of the I-beam by the first snap-fit ​​structure 1 and the second snap-fit ​​structure 2. The first snap-fit ​​structure 1 is connected with a first angle steel 3 and a second angle steel 4 at intervals. The second snap-fit ​​structure 2 is connected with a third angle steel 5 and a fourth angle steel 6 at intervals. The adjusting bolts 7 on the first angle steel 3 and the third angle steel 5 are rotated to abut against the stiffener 9, so that the stiffener 9 abuts against the springs 8 of the second angle steel 4 and the fourth angle steel 6 and moves along the first direction A or the second direction B, so that the stiffener 9 is assembled and welded to the I-beam.

[0021] The first clamping structure 1 is fixed to the upper flange of the I-beam by the first shear jack 10, and the second clamping structure 2 is fixed to the lower flange of the I-beam by the second shear jack 11. The two ends of the stiffening plate 9 are fixed between the first clamping structure 1 and the second clamping structure 2 by adjusting bolts 7 and springs 8 respectively. By rotating the adjusting bolts 7, the fixed position of the stiffening plate 9 on the side of the I-beam is changed, thereby realizing the assembly and welding work between the stiffening plate 9 and the I-beam.

[0022] Furthermore, such as Figure 1 and Figure 2 As shown, the adjusting bolts 7 screwed onto the first angle steel 3 and the third angle steel 5 are respectively aligned with the springs connected to the second angle steel 4 and the fourth angle steel 6 in the horizontal direction; the first snap-fit ​​structure 1 includes a first connecting plate 101 and a second connecting plate 102. The second connecting plate 102 is vertically connected to the first connecting plate 101. A first shear jack 10 is connected to the center of the first connecting plate 101. The first angle steel 3 and the second angle steel 4 are connected at intervals on the side of the second connecting plate 102 away from the first connecting plate 101. The first shear jack 10 abuts against the upper flange of the I-beam, so that the first angle steel 3 and the second angle steel 4 abut against the side of the upper flange of the I-beam away from the first shear jack 10.

[0023] A first notch 12 is formed between the first angle steel 3 and the second angle steel 7, so that the stiffening plate 9 abuts against the upper flange of the I-beam along the first notch 12; the adjusting bolt 7 screwed on the first angle steel 3 is rotated clockwise, so that one end of the stiffening plate 9 moves in the first notch 12 along the first direction A; the adjusting bolt 7 screwed on the first angle steel 3 is rotated counterclockwise, so that the spring 8 on the second angle steel 4 drives one end of the stiffening plate 9 to move in the first notch 12 along the second direction B.

[0024] In a preferred embodiment, when the I-beam is placed horizontally, the first direction A is to move to the left along the length of the I-beam; the second direction B is to move to the right along the length of the I-beam.

[0025] In this embodiment, adjusting bolts 7 are screwed to the center positions of the first angle steel 3 and the third angle steel 5 respectively. Preferably, openings are made on the first angle steel 3 and the third angle steel 5 respectively, and connecting bolts are welded to the openings, so that the adjusting bolts 7 are screwed onto the first angle steel 3 and the third angle steel 5.

[0026] Meanwhile, springs 8 are fixedly connected to the second angle steel 4 and the fourth angle steel 6 on the side close to the first angle steel 3 and the third angle steel 5, respectively. Preferably, two springs 8 can be connected at intervals along the length direction of the second angle steel 4 and the fourth angle steel 6. Furthermore, the adjusting bolts 7 screwed on the first angle steel 3 and the third angle steel 5 are respectively aligned with the springs connected on the second angle steel 4 and the fourth angle steel 6 in the horizontal direction. Thus, the movement of the stiffening plate 9 in the first direction A and the second direction B can be realized by adjusting the bolts 7 and the springs 8.

[0027] Specifically, the first snap-fit ​​structure 1 consists of a first connecting plate 101 and a second connecting plate 102. The second connecting plate 102 is vertically welded to the first connecting plate 101, and a first shear jack 10 is fixedly connected to the center of the first connecting plate 101. A first angle steel 3 and a second angle steel 4 are welded at intervals on the side of the second connecting plate 102 away from the first connecting plate 101. The first angle steel 3 and the second angle steel 4 are abutted against the lower part of the upper flange of the I-beam. By adjusting the first shear jack 10, the end of the first shear jack 10 away from the first connecting plate 101 abuts against the upper part of the upper flange of the I-beam, thereby fixing the first angle steel 3 and the second angle steel 4 on the upper flange of the I-beam.

[0028] Preferably, a first notch 12 is formed between the first angle steel 3 and the second angle steel 4 located below the upper flange of the I-beam. The stiffening plate 9 abuts against the lower part of the upper flange of the I-beam along the first notch 12. Then, by rotating the adjusting bolt 7 screwed on the first angle steel 3 clockwise, one end of the stiffening plate 9 moves in the first notch 12 along the first direction A. Or, by rotating the adjusting bolt 7 screwed on the first angle steel 3 counterclockwise, the spring 8 on the second angle steel 4 drives one end of the stiffening plate 9 to move in the first notch 12 along the second direction B, thereby completing the assembly of the end of the stiffening plate 9 with the upper flange of the I-beam.

[0029] Furthermore, such as Figure 1 and Figure 2 As shown, the second snap-fit ​​structure 2 includes a third connecting plate 201 and a fourth connecting plate 202. The fourth connecting plate 202 is vertically connected to the third connecting plate 201. A second shear jack 11 is connected to the center of the third connecting plate 201. A third angle steel 5 and a fourth angle steel 6 are connected at intervals on the side of the fourth connecting plate 202 away from the third connecting plate 201. The second shear jack 11 abuts against the lower flange of the I-beam, so that the third angle steel 5 and the fourth angle steel 6 abut against the side of the lower flange of the I-beam away from the second shear jack 11.

[0030] A second notch 13 is formed between the third angle steel 5 and the fourth angle steel 6, so that the end of the stiffening plate 9 away from the upper flange of the I-beam abuts against the lower flange of the I-beam along the second notch 13; the adjusting bolt 7 screwed on the third angle steel 5 is rotated clockwise, so that the end of the stiffening plate 9 away from the upper flange of the I-beam moves in the second notch 13 along the first direction A; the adjusting bolt 7 screwed on the third angle steel 5 is rotated counterclockwise, so that the spring 8 on the fourth angle steel 6 drives the end of the stiffening plate 9 away from the upper flange of the I-beam to move in the second notch 13 along the second direction B.

[0031] In this embodiment, preferably, the second snap-fit ​​structure 2 consists of a third connecting plate 201 and a fourth connecting plate 202. The fourth connecting plate 202 is vertically welded to the third connecting plate 201, and a second shear jack 11 is fixedly connected to the center of the third connecting plate 201. A third angle steel 5 and a fourth angle steel 6 are welded at intervals on the side of the fourth connecting plate 202 away from the third connecting plate 201. The third angle steel 5 and the fourth angle steel 6 are abutted above the lower flange of the I-beam. By adjusting the second shear jack 11, the end of the second shear jack 11 away from the third connecting plate 201 abuts below the upper flange of the I-beam, thereby fixing the third angle steel 5 and the fourth angle steel 6 on the upper flange of the I-beam.

[0032] First, the first snap-fit ​​structure 1 is fixed to the upper flange of the I-beam. Then, by adjusting the contact position of the second shear jack 11, the second shear jack 11 and the first shear jack 10 are aligned vertically, thereby ensuring that the second snap-fit ​​structure 2 and the first snap-fit ​​structure 1 are symmetrically arranged.

[0033] Preferably, a second notch 13 is formed between the third triangular steel 5 and the fourth angle steel 6 located above the lower flange of the I-beam. The end of the stiffening plate 9 away from the upper flange of the I-beam abuts against the upper flange of the I-beam along the second notch 13. Then, by rotating the adjusting bolt 7 screwed on the third angle steel 5 clockwise, the end of the stiffening plate 9 moves in the second notch 13 along the first direction A. Or, by rotating the adjusting bolt 7 screwed on the third angle steel 5 counterclockwise, the spring 8 on the fourth angle steel 6 drives the stiffening plate 9 to move in the second notch 13 along the second direction B. This completes the assembly of the end of the stiffening plate 9 with the lower flange of the I-beam, making both ends of the stiffening plate 9 perpendicular to the upper flange and the lower flange of the I-beam, respectively. The stiffening plate 9 can then be welded to the side of the I-beam.

[0034] The working principle of the I-beam side stiffener assembly device in this utility model is as follows: First, place the first angle steel 3 and the second angle steel 4 below the upper flange of the I-beam, and adjust the first shear jack 10 to abut against the upper flange of the I-beam so that the first angle steel 3 and the second angle steel 4 abut against the lower flange of the I-beam. Then, place the third angle steel 5 and the fourth angle steel 6 above the lower flange of the I-beam, adjust the second shear jack 11 and the first shear jack 10 to be in a straight line, and make the second shear jack 11 abut against the lower flange of the I-beam, and make the third angle steel 5 and the fourth angle steel 6 abut against the upper flange of the I-beam. Then, place the two ends of the stiffening plate 9 into the first notch 12 and the second notch 13 respectively, so that the two ends of the stiffening plate 9 are initially aligned with the upper flange and the lower flange of the I-beam respectively. Then, rotate the adjusting bolts 7 of the first angle steel 3 and the third angle steel 5 so that the stiffening plate 9 is vertically set between the upper flange and the lower flange of the I-beam. Then, weld the end of stiffener 9 to the upper flange and lower flange of the I-beam; Finally, the stiffening plate sidewalls are welded to the side of the I-beam.

[0035] Based on the I-beam side stiffener assembly device, this utility model not only eliminates the need for welding of positioning plates, but also has a micro-adjustment function, which improves the assembly quality and efficiency, and reduces the labor intensity of operators and construction costs.
