Description
Technical Field
[0001] This utility model belongs to the field of steel structure technology, and relates to a steel structure connection device, especially an adjustable steel structure connection device. Background Technology
[0002] During the construction of steel structure workshops, certain construction errors are prone to occur. When these errors are significant, the connection requirements between the steel structural component and surrounding components cannot be met. If welding is used to compensate for these errors, the quality of the welds cannot be guaranteed, leading to a reduction in the safety of the steel frame. Existing adapters are often only suitable for straight-line adjustments in the height or length direction. For potential angular errors, existing adapters require complex structures, resulting in high costs. Such adapters are generally only used in small steel or aluminum structures and are not suitable for widespread application in steel structure workshop construction. Therefore, it is necessary to provide a simple adapter that can easily adjust for both straight-line and angular errors in the steel structure. Utility Model Content
[0003] The purpose of this utility model is to provide an adjustable steel structure connection device to solve the technical problem that the adapter cannot use a simple structure to comprehensively adjust the straightness and angular errors of the steel structure.
[0004] To achieve the above objectives, the specific technical solution of this utility model is as follows:
[0005] An adjustable steel structure connection device includes a base connecting seat, a side column mounting seat, and a side column connecting seat. The base connecting seat includes a base plate and a connecting plate. There are two connecting plates, which are welded to each other on the top surface of the base plate. The connecting plates are provided with horizontal waist-shaped holes.
[0006] The side column mounting base is a right-angled C-shaped base, and there are two of them. The two side column mounting bases are interlocked. The bottom surface of the side column mounting base is perpendicular to the base plate and the connecting plate, and the side surface is parallel to the connecting plate. The side surface is provided with horizontal waist-shaped holes corresponding to the connecting plate. The two side column mounting bases and the connecting plate are fixedly connected by fixing bolts and horizontal waist-shaped holes.
[0007] There are two side column connecting seats, which are respectively set on the outer side of the bottom surface of the two side column mounting seats. The side column connecting seat includes an angle adjusting shaft, an adjusting sleeve and a steel structure mounting plate. One end of the angle adjusting shaft is welded to the outer side of the bottom surface of the side column mounting seat. Multiple keyways are evenly arranged on the side of the angle adjusting shaft. The adjusting sleeve is fitted on the angle adjusting shaft and is tightly fitted with the angle adjusting shaft through a connecting key. The steel structure mounting plate is welded to the end face of the adjusting sleeve on the side away from the side column mounting seat.
[0008] The two side column mounting seats are side column mounting seat A and side column mounting seat B. Side column mounting seat A includes a side plate A and a fixing plate A, and side column mounting seat B includes a side plate B and a fixing plate B.
[0009] The side column mounting base A is disposed between the two connecting plates, and the fixing plate A is perpendicular to the bottom plate connecting plate, and the outer side surface of the side plate A is in contact with the inner side surface of the connecting plate.
[0010] The side column mounting base B is disposed between the two side plates A of the side column mounting base A. The fixing plate B is parallel to the fixing plate A, and the outer side surface of the side plate B is in contact with the inner side surface of the side plate A.
[0011] Each of the connecting plates and side column mounting bases has two horizontal waist-shaped holes on one side, and both sides of the two connecting plates and side column mounting bases are provided with horizontal waist-shaped holes.
[0012] The angle between adjacent keyways ranges from 5 to 20°.
[0013] The mounting plate is provided with a locking hole A, and the bottom surface of the side column mounting base is provided with a locking hole B. The locking hole A coincides with the axis of the adjusting sleeve, and the locking hole B coincides with the axis of the angle adjusting shaft. The locking hole A and the locking hole B have the same diameter. The side column connecting base and the side column mounting base are locked together by locking bolts and locking holes A and B.
[0014] The locking bolt is an internal hexagonal bolt.
[0015] The beneficial effects of this utility model are as follows: By providing an adjustable steel structure connection device, and by setting a base connecting seat and two side column connecting seats, when a straight line error occurs in the steel structure, the straight line error between the two steel structures can be eliminated by adjusting the relative positions of the two side column connecting seats relative to the base connecting seat. At the same time, by setting side column connecting seats on the side column mounting seats, when an angular error occurs between two adjacent cylinder structures, the angular error between the two adjacent steel structures can be eliminated by adjusting the relative positions of the adjusting sleeve and the angle adjusting shaft. The structure is simple and reliable, low in cost, and has strong stability and high safety after being installed in the steel structure. It is suitable for widespread application in the construction of large steel structure workshops. Attached Figure Description

[0021] To better understand the purpose, structure, and function of this utility model, a more detailed description of this utility model is provided below with reference to the accompanying drawings.
[0022] like Figures 1 to 4 As shown, this utility model provides an adjustable steel structure connection device, which includes a base connecting seat 1, a side column mounting seat 2, and a side column connecting seat 3. The base connecting seat 1 is used to fix on the steel structure column and install other parts. Specifically, it includes a base plate 101 and a connecting plate 102. The base plate 101 has through holes on its four edges for bolts to pass through and for fixing to the steel structure column. There are two connecting plates 102, which are welded to each other on the top surface of the base plate 101. The connecting plate 102 has horizontal waist-shaped holes 5 for fixing and connecting the side column mounting seat 2 and the side column connecting seat 3.
[0023] The side column mounting bases 2 are C-shaped at right angles, and there are two of them: side column mounting base A201 and side column mounting base B202, which are interlocked. Side column mounting base A201 includes a side plate A10 and a fixing plate A11, while side column mounting base B202 includes a side plate B12 and a fixing plate B13. Side column mounting base A201 is positioned between the two connecting plates 102. The fixing plate A11 is perpendicular to both the base plate 101 and the connecting plate 102, and the outer surface of the side plate A10 contacts the inner surface of the connecting plate 102. Side column mounting base B202 is positioned between the two side plates A10 of side column mounting base A201. The fixing plate B13 is parallel to the fixing plate A11, and the outer surface of the side plate B12 contacts the inner surface of the side plate A10. Side plate A10 and side plate B12 are respectively provided with horizontal waist-shaped holes 5 corresponding to connecting plate 102. Side column mounting base A201, side column mounting base B202 and connecting plate 102 are fixedly connected by fixing bolts 4 and horizontal waist-shaped holes 5.
[0024] Corresponding to the side column mounting base 2, there are two side column connecting bases 3, respectively disposed on the outer side of the bottom surface of the two side column mounting bases 2, for connecting two adjacent steel structure components. Specifically, the side column connecting base 3 includes an angle adjusting shaft 6, an adjusting sleeve 7, and a steel structure mounting plate 8. The angle adjusting shaft 6 and the adjusting sleeve 7 are separately disposed. One end of the angle adjusting shaft 6 is welded to the outer side of the bottom surface of the side column mounting base 2. Multiple keyways 9 are evenly arranged on the side surface of the angle adjusting shaft 6. The adjusting sleeve 7 is fitted onto the angle adjusting shaft 6 and is tightly fitted with the angle adjusting shaft 6 by a connecting key. The steel structure mounting plate 8 is welded to the end face of the adjusting sleeve 7 on the side away from the side column mounting base 2. The angle range between adjacent keyways 9 is 5°-20°. In this embodiment, in order to give the sidewall of the keyway 9 a certain shear resistance, 20° is selected. When an angular error occurs between two adjacent steel structure components, the keyway 9 that matches the adjusting sleeve 7 and the angle adjusting shaft 6 is adjusted so that the mounting plate can be adjusted to a certain angle to eliminate or reduce the error, thereby connecting the two adjacent steel structure components together.
[0025] To improve the stability of the connection between the side column mounting base 2 and the base connecting base 1, in this embodiment, two horizontal oblong holes 5 are provided on one side of each connecting plate 102 and the side column mounting base 2, and horizontal oblong holes 5 are provided on both sides of the two connecting plates 102 and the side column mounting base 2. The two side column mounting bases 2 are fixed to the base connecting base 1 by four fixing bolts 4, which can improve the stability of the connection device during application, thereby improving the overall stability of the steel structure.
[0026] Meanwhile, to improve the stability and reliability of the connection between the mounting plate of the side column connecting seat 3 and the fixing plate of the side column mounting seat 2, in this embodiment, a locking hole A is provided on the mounting plate, and locking holes B are respectively provided on the fixing plate A11 and fixing plate B13 of the side column mounting seat 2. The locking hole A coincides with the axis of the adjusting sleeve 7, and the locking hole B coincides with the axis of the angle adjusting shaft 6. The diameters of the locking holes A and B are the same. The side column connecting seat 3 and the side column mounting seat 2 are locked together by the locking bolt 14 and the locking holes A and B. In this embodiment, in order not to affect the connection between the mounting plate and the steel structure component, the locking bolt 14 is preferably a countersunk hexagonal socket head cap bolt.
