Description

Technical Field

[0001] This application relates to the field of cross-shaped column welding technology, and specifically discloses a cross-shaped column welding device. Background Technology

[0002] Steel structures are favored for their light weight, good seismic performance, small footprint, excellent spatial feel, and unique environmental advantages. Therefore, an increasing number of high-rise buildings are using steel structures as their main structure. Cross-shaped columns are quite common in high-rise buildings, mainly due to their simple construction and high rigidity. With the accelerating pace of social development, steel structures are becoming increasingly widely used due to their simple fabrication, ease of transporting overall or partial components, rapid on-site hoisting and construction, high seismic and fire resistance, energy efficiency, environmental friendliness, good ductility, and short construction time.

[0003] Cross-shaped steel columns in steel structures are increasingly widely used in steel structure engineering due to their advantages such as good bidirectional load-bearing performance, high stability, and high stiffness, especially in steel-concrete structures of high-rise buildings. A cross-shaped column consists of one H-beam and two T-beams. According to the design drawings, different combinations of H-beams and T-beams can be selected, thus reducing the difference in cross-section and increasing the range of choices. Furthermore, the cross-shaped cross-section has similar moments of inertia, bending moduli, and radii of gyration in the two principal axes, greatly improving its stability. This solves the problem of insufficient load-bearing capacity when using wide-flange steel sections and achieves the goal of rational material utilization.

[0004] Regarding the cross column, which is made by welding an H-beam and two T-beams, the core issue is how to accurately install the two T-beams on the horizontal centerline of the H-beam. In view of this, the inventor proposes a cross column welding device. Utility Model Content

[0005] The purpose of this invention is to solve the problem that traditional cross-shaped columns composed of one H-beam and two T-beams cannot ensure that the two T-beams are accurately installed on the horizontal centerline of the H-beam.

[0006] To achieve the above objectives, this utility model provides the following basic solution:

[0007] A cross-shaped column welding device includes a workstation, an installation slot on the workstation, a lifting assembly installed in the installation slot, a lifting plate disposed at the lifting end of the lifting assembly, a placement plate fixed to the workstation, and a pushing assembly. The placement plate, the pushing assembly, and the lifting plate are used to fix H-beams. The device also includes a positioning assembly for fixing the length and center of the H-beams. T-beams are welded to both sides of the H-beams. The upper T-beams are hoisted and welded, and the lower T-beams are welded to the H-beams after the lifting plate lowers to leave installation space.

[0008] Furthermore, the placement plate is fixed to the left side of the workstation located in the mounting slot, and the pushing component is fixed to the right side of the workstation located in the mounting slot. The pushing component includes a first cylinder and a first cylinder mounting seat. The first cylinder mounting seat is fixed to the workstation, and the first cylinder is mounted on the first cylinder mounting seat. A pressing plate is fixed to the extended end of the first cylinder.

[0009] Furthermore, the lifting assembly is a second cylinder, which is installed in the mounting groove. The lifting plate is installed at the extended end of the second cylinder. When the H-beam is fixed, the end face of the lifting plate is flush with the workstation surface. When the T-beam on the lower side is welded, the lifting plate retracts into the mounting groove.

[0010] Furthermore, the positioning component includes a fixed-length structure and a fixed-distance structure. The fixed-length structure includes a flat plate fixed to the placement plate and the extrusion plate respectively, a distance sensing receiver target and a distance sensing transmitter respectively mounted on the flat plate, and the distance sensing receiver target and the distance sensing transmitter are both embedded in the end face of the flat plate and kept flush with the end face of the flat plate.

[0011] Furthermore, the distance-fixing structure consists of a ruler and a marker pen. The marker pen marks three sets of points based on the ruler. The first set of points is the center point of the H-beam, the second set of points is the welding distance of the T-beam reflected on the upper horizontal level of the H-beam, and the third set of points is the welding distance of the T-beam reflected on the lower horizontal level of the H-beam.

[0012] Furthermore, it also includes a hoisting device, which, after being hoisted with one of the T-shaped steel sections, is welded to the upper surface of the H-shaped steel section, with the welded surface of the T-shaped steel section corresponding to the second set of points.

[0013] Furthermore, as the lifting plate in the lifting assembly descends, another T-shaped steel is inserted, and the welded surface of the T-shaped steel corresponds to the third set of points.

[0014] The principle and effect of this solution are as follows:

[0015] 1. Compared with the prior art, the cross column applicable to this utility model is welded from one H-beam and two T-beams. This type of cross column is the most common. The feature of this device is that it prioritizes fixing the H-beam, finds the center line of the H-beam based on the fixing of the H-beam, and determines the distance of the center line of the H-beam. Then, based on this center line and the welding surface of the T-beam, it finds the length of the welding surface of the T-beam and then realizes the welding of the T-beam. At this time, the welding becomes simple and precise. It is only necessary to align the T-beam with the welding surface of the H-beam and weld it. This device solves the problem that the traditional cross column composed of one H-beam and two T-beams cannot ensure that the two T-beams are accurately installed on the horizontal centerline of the H-beam.

[0016] 2. Compared with the existing technology, this device is equipped with an installation slot and a lifting component installed in the installation slot. The lifting component enables the lifting plate to move up and down. When the lifting plate moves up and down, it has advantages for the installation and placement of another T-shaped steel without affecting the fixation of the T-shaped steel.

[0021] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0022] The reference numerals in the accompanying drawings include: H-beam 1, T-beam 2, workstation 3, mounting slot 4, second cylinder 5, lifting plate 6, placement plate 7, flat plate 8, distance sensor receiver target 9, distance sensor transmitter 10, first cylinder 11, first cylinder mounting base 12, ruler 13, second set of points 14, third set of points 15.

[0023] Implementation, for example Figure 1 , Figure 2 and Figure 3 As shown:

[0024] A cross-shaped column welding device includes a work station 3, an installation groove 4 opened on the work station 3, a lifting component installed in the installation groove 4, a lifting plate 6 set at the lifting end of the lifting component, a placement plate 7 fixed to the work station 3, and a pushing component. The placement plate 7, the pushing component, and the lifting plate 6 are used to fix H-beam 1. The device also includes a positioning component for fixing the length and center of H-beam 1. T-beams 2 are welded to both sides of H-beam 1. The upper T-beam 2 is hoisted and welded, and the lower T-beam 2 is lowered based on the lifting plate 6 to leave installation space before being welded to H-beam 1.

[0025] Specifically:

[0026] like Figure 2 As shown, the placement plate 7 is fixed to the left side of the mounting groove 4 at the work station 3, and the pushing component is fixed to the right side of the mounting groove 4 at the work station 3. The pushing component includes a first cylinder 11 and a first cylinder mounting seat 12. The first cylinder mounting seat 12 is fixed to the work station 3, and the first cylinder 11 is mounted on the first cylinder mounting seat 12. A pressing plate is fixed to the extended end of the first cylinder 11.

[0027] The extrusion plate moves to the left by starting the first cylinder 11. The lifting assembly is the second cylinder 5, which is installed in the mounting groove 4. The lifting plate 6 is installed at the extended end of the second cylinder 5. When the H-beam 1 is fixed, the end face of the lifting plate 6 is flush with the surface of the work station 3. When the T-beam 2 on the lower side is welded, the lifting plate 6 retracts into the mounting groove 4.

[0028] The H-beam 1 is placed horizontally on the lifting plate 6, with the left side of the H-beam 1 in contact with the placement plate 7. The first cylinder 11 is activated, and the pressing plate moves to the left to press the right side of the H-beam 1, thus fixing the H-beam 1.

[0029] Then, regarding the positioning component:

[0030] The positioning component includes a fixed-length structure and a fixed-distance structure. The fixed-length structure includes a flat plate 8 fixedly attached to the placement plate 7 and the extrusion plate, a distance sensing receiver 9 and a distance sensing transmitter 10 respectively mounted on the flat plate 8. The distance sensing receiver 9 and the distance sensing transmitter 10 are both embedded in the end face of the flat plate 8 and are flush with the end face of the flat plate 8.

[0031] After fixing the H-beam 1, the distance between the distance sensing receiver 9 and the distance sensing transmitter 10 can be clearly obtained. Then, this distance is divided by two to get a new value. The distance setting structure is a ruler 13 and a marker pen. The marker pen marks three sets of points based on the ruler 13. The first set of points is the center point of the H-beam 1. The second set of points 14 is the welding distance of the T-beam 2 reflected on the upper horizontal level of the H-beam 1. The third set of points 15 is the welding distance of the T-beam 2 reflected on the lower horizontal level of the H-beam 1.

[0032] Align the zero mark of ruler 13 with the left side of H-beam 1, and then mark the point with the new value mentioned above. This point is the first set of points. Then, because of the welding, the length of the bottom weld surface of T-beam 2 is known. Mark the second set of points 14 based on the first set of points and the length of the bottom weld surface of T-beam 2. Similarly, mark the third set of points 15 through this operation.

[0033] It also includes a hoisting device, which hoists one of the T-shaped steels 2 and then welds it to the upper surface of the H-shaped steel 1. The welding surface of the T-shaped steel 2 corresponds to the second set of 14 points to realize the welding of the T-shaped steel 2.

[0034] Then, the lifting plate 6 in the lifting assembly descends, and after descending, another space for filling the T-shaped steel 2 is opened. After the T-shaped steel 2 is filled, the welding surface of the T-shaped steel 2 corresponds to the third set of points 15, and the T-shaped steel 2 can be welded.

[0035] This device solves the problem that the traditional cross column composed of one H-beam 1 and two T-beams 2 cannot ensure that the two T-beams 2 are accurately installed on the horizontal centerline of the H-beam 1.

[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
