Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of steel structures, and particularly relates to an H-shaped steel butt joint tooling for steel structures. Background Technique
[0002] In the field of steel structure fabrication and installation, there are mainly the following several H-shaped steel butt joint methods: ① Level, align, and spot weld the H-shaped steel on the platform and then weld it. The advantage of this method is that the process is mature and it is mostly used in factory processing. The disadvantages are that it has high requirements for the flatness of the processing platform and is limited by the size of the fabrication platform, and it is not suitable for the butt joint of H-shaped steel of larger components; ② Adopt the bolt-welding method. In this method, holes are drilled on the flange plates and webs of the H-shaped steel or ear plates are welded on the flange plates, and then the H-shaped steel is connected by connecting plates and bolts, and then the flange plates of the H-shaped steel are welded. The advantage of this method is that it has low requirements for the on-site construction environment and is easy to operate; the disadvantage is that the connecting plates and ear plates on the flange plates need to be cut off after welding, resulting in large material waste and high processing costs. This method is mainly used for the butt joint of H-shaped steel columns at the steel structure installation site; ③ Adopt tooling fixtures to assist in aligning the H-shaped steel and then weld it. The advantage of this method is that there are many types of tooling, which can be selected or fabricated according to requirements, and it has a wide application range and can be used in both factory fabrication and on-site installation. The disadvantages are that some fixture structures are relatively complex, the operation is inconvenient, and the cost is relatively high.
[0003] Regarding the H-shaped steel butt joint tooling, there are currently three main types. One is to open holes on the H-shaped steel and use fastening devices such as connecting components and bolts to fix and clamp the H-shaped steel and then perform butt joint welding. The disadvantage of this type of tooling is that it is necessary to open holes on the H-shaped steel, the operation is relatively complex, and the cost is relatively high; the second is to use two U-shaped card slots to respectively clamp the two sides of the flange plates of the H-shaped steel butt joint, and fasten the two card slots with bolts, and then perform the butt joint welding of the H-shaped steel; the disadvantage of this type of tooling is that there is no adjusting bolt in the axial direction of the H-shaped steel. When adjusting the axial direction of the H-shaped steel, it is necessary to remove the bolts of the card slot, and the operation is inconvenient; the third includes a monitoring component, a fixing frame, an electromagnetic coil, a limiting component, etc., and is an H-shaped steel automatic butt joint welding tooling that can automatically correct and automatically butt joint. This type of tooling has a complex structure and a very high cost, and is rarely used in the fields of steel structure fabrication and installation. Therefore, in view of the above problems, it is necessary to make improvements. Content of the Utility Model

[0021] The specific structure of the adjustment device is as follows: The adjustment device includes a long screw 6. A vertically arranged reinforcing rib plate 9 is fixed on the base 11, and one end of the long screw 6 is fixed on the outer side plate surface of the reinforcing rib plate 9. The other end of the long screw 6 passes through the upper through hole of the U-shaped clamp I 4 and is adaptively connected to a locking nut 1, and the U-shaped clamp I 4 whose lower end is clamped with the same side plate edge of the flange plate of the H-shaped steel 10 is locked and fixed by adjusting the locking nut 1; in the above structure, by fixing the U-shaped clamp II 5 at one end of the base 11 and connecting the U-shaped clamp I 4 to the base 11 through the adjustment device at the other end, under the action of the adjustment device, the U-shaped clamp I 4 and the U-shaped clamp II 5 are respectively clamped with the plate edges of the flange plates on both sides of the butt joint of the H-shaped steel 10, and the position of the U-shaped clamp I 4 is adjusted by adjusting the locking nut 1, so as to adapt to the flange plate widths of different H-shaped steels 10, increase the application range and meet the requirements for the clamping widths of different models of H-shaped steels 10;

A through hole is formed on the vertical plate 8 between the two reinforcing rib plates 9, and the axial bolt 3 passes through the through holes on the vertical plate 8 of the two H-shaped steels 10 and is adaptively connected with a nut. The inner end of the upper end of the U-shaped clamp II 5 is fixedly connected with the corresponding end of the base plate 7. In the above structure, the two bases 11 on the two H-shaped steels 10 are axially tensioned and fixed by the axial bolt 3, and the distance between the two vertical plates 8 is adjusted by the axial bolt 3, so as to meet the requirements of the butt joint gap distance between the two H-shaped steels 10 under different weld requirements.
[0023] In order to adapt to the reliable clamping of the flange plates of different models of H-shaped steels 10 with the U-shaped clamp I 4 and the U-shaped clamp II 5, the two side edges of the flange plate of the H-shaped steel 10 are respectively adapted to the clamping grooves of the U-shaped clamp I 4 and the U-shaped clamp II 5.

Then, in the axial direction of H-shaped steel 10, use axial bolt 3 and nut to fasten the two bases 11 on both sides of the H-shaped steel 10 interface; among them, mainly adjust the position of U-shaped clamp Ⅰ4 through lock nut 1 to adapt to the flange width of different H-shaped steels 10; use inclined shim 2 to clamp H-shaped steels 10 with different flange thicknesses; at the same time, in the axial direction of H-shaped steel 10, adjust the distance between the vertical plates 8 in the base 11 through axial bolt 3 to meet the butt joint gap distance under different weld requirements, so as to realize the adjustment, alignment and fastening during the butt joint of H-shaped steel 10.
