Description

Technical Field

[0001] This utility model relates to the field of construction tools technology, and more specifically, to a tool for straightening butt welds of plates. Background Technology

[0002] Currently, in the construction field, the fabrication and installation of steel structures and large tanks are often constrained by relevant fabrication and installation specifications, as well as the requirement to save material consumption. This often involves joining two smaller steel plates together and then welding the joint to form a larger plate, which is then used for subsequent construction work.

[0003] However, when joining two steel plates, the heat generated during welding causes some areas of the weld to expand on one side and contract on the other, resulting in welding stress. This causes deformation of the weld joint (mainly upward or downward warping at certain points), making the upper surface of the finished steel plate not on the same horizontal plane. If the deformation at the weld joint cannot be corrected, subsequent construction work cannot be carried out.

[0004] Existing methods often involve using a small hammer to strike around the weld to release stress, and a large hammer to strike and correct the weld joint. However, this method is time-consuming, labor-intensive, and difficult to control the striking force.

[0005] Therefore, an easy-to-operate solution for correcting splicing welds is needed. Utility Model Content

[0006] In view of the above problems, the purpose of this utility model is to provide a tool for straightening butt welds of plates, so as to solve the problems of difficult operation and low efficiency of existing straightening schemes for splicing welds of two steel plates.

[0007] The tool for straightening butt welds of plates provided by this utility model includes a flat support plate positioned above two spliced ​​steel plates to be straightened.

[0008] A weld seam is formed between the two spliced ​​steel plates. A lower longitudinal stiffener plate corresponding to the weld seam is fixedly connected to the lower surface of the flat support plate. The lower longitudinal stiffener plate is fixed to the weld seam.

[0009] Furthermore, in a preferred configuration, jacks are placed on both of the aforementioned splicing steel plates; and,

[0010] The upper ends of both jacks are pressed against the flat support plate.

[0015] Furthermore, a preferred structure is that an upper transverse stiffener is fixedly connected to the upper surface of the flat support plate, and the upper transverse stiffener is perpendicular to the lower longitudinal stiffener.

[0016] Furthermore, a preferred structure is that support point ribs are fixed on the upper surface of the flat support plate, located on both sides of the upper transverse rib plate, and the support point ribs are fixed to the sides of the upper transverse rib plate.

[0017] Furthermore, a preferred structure is that the vertical cross-section of the support point stiffener plate is a right-angled triangle; and,

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0035] Figure 1 The front view of the plate butt weld straightening tool provided in an embodiment of the present invention is shown. Figure 2 The diagram shows a top view of the plate butt weld straightening tool provided in an embodiment of the present invention. Figure 3 The side view of the plate butt weld straightening tool provided in an embodiment of the present invention is shown. Figure 4 The principle of the plate butt weld straightening tool provided in the embodiment of this utility model during use is illustrated.

[0036] Combination Figures 1 to 4 As shown, the plate butt weld straightening tool provided in the embodiment of this utility model includes a flat support plate 1 positioned above two spliced ​​steel plates 6 to be straightened. The flat support plate 1 is basically parallel to the two spliced ​​steel plates 6 to be straightened, and a certain space is reserved between them. It should be noted that the two spliced ​​steel plates 6 need to be connected by welding first. Therefore, a weld area 7 (strip weld) is formed between the two spliced ​​steel plates 6. A lower longitudinal stiffening plate 2 (whose cross-section is also a strip structure) is fixedly connected (preferably by welding) to the lower surface of the flat support plate 1, corresponding to the weld area 7. The lower longitudinal stiffening plate 2 is perpendicular to the flat support plate 1 (usually, the flat support plate 1 is horizontal, and the lower longitudinal stiffening plate 2 is vertical). The lower longitudinal stiffening plate 2 needs to be pre-fixed to the weld area 7.

[0037] Specifically, to achieve the correction and adjustment of the weld zone 7 between the two steel plates, jacks 5 are placed on both spliced ​​steel plates 6; and the upper ends of the two jacks 5 are pressed against the flat support plate 1. In actual operation, for the upward-curving weld zone 7, as the jacks 5 are lifted, the flat support plate 1 will exert a downward force on the lower longitudinal rib, and the lower longitudinal rib plate 2 will press down on the weld zone 7 at that position to correct it to a horizontal position; for the downward-curving weld zone 7, as the jacks 5 are lifted, the flat support plate 1 will exert an upward force on the lower longitudinal rib, and the lower longitudinal rib plate 2 will pull up on the weld zone 7 at that position to correct it to a horizontal position.

[0038] In addition, it should be noted that in order to improve the correction effect of weld zone 7, the two jacks 5 can be placed on both sides of the lower longitudinal stiffening plate 2. In actual operation, for a certain weld zone 7, the correction can be achieved by simultaneously lifting the jacks 5 on both sides, which can ensure that both sides of the weld zone 7 can reach the horizontal position.

[0039] also, Figure 5 This illustration shows a partial side cross-sectional view of the weld zone 7 provided in an embodiment of the present invention, consisting of... Figure 5 It is understood that, in order to achieve the pre-fixation between the longitudinal stiffening plate and the weld area 7, the lower longitudinal stiffening plate 2 and the weld area 7 can be fixedly connected by skip welding (i.e., spot welding); and, to ensure the fixing effect between the longitudinal stiffening plate and the weld area 7, multiple spot welds are required between the lower longitudinal stiffening plate 2 and the weld area 7, that is, multiple weld points 8 (at least two weld points 8) are formed. The skip welding method can not only achieve the required pre-fixation between the longitudinal stiffening plate and the weld area 7, but also melt the weld points 8 after the entire tool is used up, and remove the butt weld straightening tool provided by this utility model.

[0040] In addition, to ensure consistent connection stability at all positions on both sides between the longitudinal stiffener plate and the weld zone 7, the aforementioned weld points 8 can be formed on both sides of the lower longitudinal stiffener plate 2; and the weld points 8 on either side can be evenly or uniformly distributed along the extension direction of the weld zone 7 to further improve connection stability.

[0041] In one specific embodiment of this utility model, to improve the stability of the entire straightening tool, an upper transverse stiffener plate 3 can be fixedly connected to the upper surface of the flat support plate 1, with the upper transverse stiffener plate 3 perpendicular to the lower longitudinal stiffener plate 2; furthermore, support point stiffener plates 4 are fixed on both sides of the upper transverse stiffener plate 3 on the upper surface of the flat support plate 1, with the support point stiffener plates 4 fixed to the sides of the upper transverse stiffener plate 3. This arrangement ensures the flat support plate 1 has strong stability, preventing it from bending or breaking under the action of the jack 5, thus ensuring the normal use of the entire plate butt weld straightening tool.

[0042] Furthermore, to further enhance the support stability of the flat support plate 1, the vertical section of the support point rib plate 4 can be designed as a right-angled triangle. The support point rib plate 4 has a bottom right-angled surface and a side right-angled surface (not marked in the figure). The bottom right-angled surface is fixed to the upper surface of the flat support plate 1, and the side right-angled surface is fixed to the side of the upper transverse rib plate 3. The planes corresponding to the two right-angled sides of the support point rib plate 4 serve as the connection surfaces between the flat support plate 1 and the upper transverse rib plate 3, significantly improving the support effect of the support point rib plate 4 and thus further enhancing the support stability of the flat support plate 1.

[0043] It should be noted that the support point stiffener plate 4 can be set up using the same principle as the welding point 8 mentioned above. That is, support point stiffener plates 4 can be fixed on both sides of the upper horizontal stiffener plate 3. Furthermore, the support point stiffener plates 4 on either side are evenly or uniformly distributed along the extension direction of the upper horizontal stiffener plate 3, thereby further improving the support effect of the support point stiffener plates 4.

[0044] As referred above Figures 1 to 5 A tool for straightening butt welds of plates according to the present invention has been described by way of example. However, those skilled in the art should understand that various modifications can be made to the tool for straightening butt welds of plates according to the present invention without departing from the scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the contents of the appended claims.
