Description

Technical Field

[0001] The invention relates to the field of construction engineering, and more particularly to an engineering rigid column connection device and method. Background Art

[0002] During the construction of large subway stations, the upper roof is designed as a truss structure. All trusses are flat trusses. The lower part uses steel pipe upright columns and tree-shaped composite steel columns with unequal elevations and special sections. The bottom of the tree-shaped columns is a composite column composed of six box-type columns. The four tree-shaped composite steel columns with unequal elevations and special sections are decorated with naked decoration technology, presenting the integrated effect of decorative steel structure construction with an overall slender, upright, prosperous and efficient appearance.

[0003] When constructing tree-like engineering rigid columns, for the sections between the first and second columns, in order to ensure the increase of welding space and welding quality, three boxes are usually reserved for patching at the connection points, and the patching of each box is divided into two sections to form two trough structures. After the concrete strength of the base reaches the requirement, the second column is hoisted, and the temporary connecting plate is installed. Then, the welds between the three boxes without patching and the first column are welded. This method not only increases the welding workload, but also the temporary connecting plate needs to be removed later, and the connecting plates welded on the first and second columns need to be cut, polished and trimmed, and the patching points also need to be polished and smoothed to improve the aesthetics of the entire tree-like engineering rigid column, resulting in the connection and assembly process of the engineering rigid column consuming a lot of time and cost.

DETAILED DESCRIPTION

[0031] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only intended to enable those skilled in the art to better understand and implement the subject matter described herein. In addition, the features described relative to some examples may also be combined in other examples.

[0032] like Figure 1-Figure 5 As shown, an engineering rigid column connection device is used for the connection process of a first-section column and a second-section column, comprising an external welding mechanism and a column internal gap welding mechanism 6, the external welding mechanism is sleeved at the intersection of the first-section column and the second-section column, and the column internal gap welding mechanism 6 is arranged inside the second-section column;

[0033] The external welding mechanism includes a sleeve-type limiting mechanism 1, a column outer gap welding mechanism 2 and an auxiliary limiting mechanism 3, which are arranged in sequence from bottom to top, a first connecting rod 4 connected between the sleeve-type limiting mechanism 1 and the column outer gap welding mechanism 2, and a second connecting rod 5 connected between the sleeve-type limiting mechanism 1 and the auxiliary limiting mechanism 3. The sleeve-type limiting mechanism 1, the column outer gap welding mechanism 2 and the auxiliary limiting mechanism 3 are coaxially arranged;

[0034] The collar-type limiting mechanism 1 comprises a first spliced ​​collar assembly and a plurality of driving wheel assemblies 103 connected to the first spliced ​​collar assembly, wherein the plurality of driving wheel assemblies 103 are used to contact with the first section column and apply a set pressure to the surface of the first section column;

[0035] The column outer gap welding mechanism 2 comprises a second spliced ​​collar assembly, a spliced ​​ring rail assembly arranged on the second spliced ​​collar assembly, an annular moving assembly slidably connected to the spliced ​​ring rail assembly, and a first welding assembly connected to the annular moving assembly, the annular moving assembly is used to drive the first welding assembly to rotate a set angle around the vertical axis of the first column section, and the first welding assembly is used to weld the gap at the intersection of the outer surface of the second column section and the first column section;

[0036] The auxiliary limiting mechanism 3 includes a third spliced ​​collar assembly and a plurality of L-shaped auxiliary limiting plugs 303 connected to the third spliced ​​collar assembly, wherein the plurality of L-shaped auxiliary limiting plugs 303 are used to contact the second section column and make the second section column coaxial with the first section column;

[0037] The in-column gap welding mechanism 6 includes an in-tube walking component and a second welding component connected to one end of the in-tube walking component. The in-tube walking component is used to drive the second welding component to move along the length direction of the second column section, and the second welding component is used to weld the gap at the intersection of the inner surface of the second column section and the first column section.

[0038] It should be noted that when the first section column and the second section column are welded and connected, after the second section column is hoisted above the first section column, the sleeve ring type limiting mechanism 1, the column outer gap welding mechanism 2, and the auxiliary limiting mechanism 3 are opened and sleeved on the outside of the first section column and the second section column, so that the sleeve ring type limiting mechanism 1 is located at the first section column, the column outer gap welding mechanism 2 is at the intersection of the first section column and the second section column, and the auxiliary limiting mechanism 3 is located at the second section column. When assembling, the openings of the first spliced ​​sleeve ring assembly, the second spliced ​​sleeve ring assembly and the third spliced ​​sleeve ring assembly are first opened, and the first section column and the second section column pass through the corresponding openings. After the first spliced ​​sleeve ring assembly, the second spliced ​​sleeve ring assembly and the third spliced ​​sleeve ring assembly are respectively sleeved on the first section column and the second section column, the openings of the first spliced ​​sleeve ring assembly, the second spliced ​​sleeve ring assembly and the third spliced ​​sleeve ring assembly are closed again. As the first spliced ​​sleeve ring assembly, the second spliced ​​sleeve ring assembly and the third spliced ​​sleeve ring assembly are installed, the sleeves are The first spliced ​​collar assembly is closed at the opening of the first spliced ​​collar assembly and the third spliced ​​collar assembly, and the driving wheel assembly 103 on the first spliced ​​collar assembly contacts the surface of the first section column and generates corresponding pressure, which causes the driving wheel assembly 103 to generate corresponding friction between the outer surface of the first section column. At this time, the first spliced ​​collar assembly and the first section column are in limited contact, and the first spliced ​​collar assembly can only move up and down along the first section column, but cannot rotate. After the first spliced ​​collar assembly contacts the concrete of the foundation, a coaxial limiting effect can be formed, and the second spliced ​​collar assembly and the third spliced ​​collar assembly are limited by the first connecting rod 4 and the second connecting rod 5, so that the first spliced ​​collar assembly, the second spliced ​​collar assembly and the third spliced ​​collar assembly are coaxial, so that the first section column and the second section column can be coaxial and are in a preliminary limited state, without the need to add additional auxiliary limiting structural parts, which effectively reduces additional costs and construction steps;

[0039] When the first section column and the second section column are in a coaxial state, the first welding assembly is driven by the annular moving assembly to move circumferentially along the spliced ​​ring track assembly. During the circumferential movement of the first welding assembly, the gap where the outer surface of the second section column and the first section column meet is welded;

[0040] At the same time, the second welding assembly is driven by the walking assembly in the tube to move to the intersection of the inner surface of the second section column and the first section column, and the gap where the inner surface of the second section column and the first section column intersect is welded by the second welding assembly. After welding, the ring-type limiting mechanism 1, the outer gap welding mechanism 2, the auxiliary limiting mechanism 3 and the inner gap welding mechanism 6 are removed.

[0041] Among them, Figure 2As shown, the first spliced ​​ring assembly includes a first annular hinge 101, two first half ring bodies 102 symmetrically connected to the inner circumferential surface of the first annular hinge 101, and a first buckle 1010 arranged at the opening of the first annular hinge 101, and a plurality of driving wheel assemblies 103 are symmetrically connected to the first half ring body 102.

[0042] It should be noted that, as mentioned above, when the first spliced ​​ring assembly is sleeved on the first column section, the first buckle 1010 on the first annular hinge 101 is first opened. At this time, the first annular hinge 101 is disconnected from the connection of the first buckle 1010. At this time, the semi-annular assembly of the first annular hinge 101 is opened around the hinge, and the first semi-ring body 102 connected to the semi-annular assembly moves synchronously with it, so that it can be clamped on the outside of the first column section from the disconnection point, and then the disconnection point of the first annular hinge 101 is closed again. After closing, the driving wheel assembly 103 connected to the first semi-ring body 102 contacts the outer surface of the first column section and generates corresponding pressure. The driving wheel assembly 103 includes a frame body and a wheel body. The wheel body is elastic. Corresponding springs can also be arranged on the frame body to provide a certain travel range for the wheel body to move radially, so that it can adapt to first columns of different diameters.

[0043] Among them, Figure 2 and Figure 3 As shown, the second spliced ​​collar assembly includes a second annular hinge 201 , two second half ring bodies 202 symmetrically connected to the inner circumferential surface of the second annular hinge 201 , and a second buckle 2010 provided at the opening of the second annular hinge 201 .

[0044] The spliced ​​ring rail assembly includes a spliced ​​half-ring gear 203 fixedly connected to the second half-ring body 202 and a spliced ​​half-ring groove 204 provided on the second half-ring body 202. When the opening of the second ring hinge 201 is closed, the two spliced ​​half-ring gears 203 form a ring gear, and the two spliced ​​half-ring grooves 204 form a ring groove.

[0045] The annular moving assembly includes a first motor 205, a fixed ring body 206 fixedly connected to the outer shell of the first motor 205, a slider 207 fixedly connected to the outer wall of the fixed ring body 206, a traveling gear 208 connected to the output shaft end of the first motor 205, and a connecting plate 209 connected to the fixed ring body 206. One end of the slider 207 is slidably connected to the inner wall of the spliced ​​half-ring groove 204, and the traveling gear 208 is meshed with the spliced ​​half-ring gear 203.

[0046] It should be noted that, as mentioned above, the opening and closing process of the second spliced ​​ring assembly is the same as the opening and closing process and principle of the first spliced ​​ring assembly. When the first welding assembly is driven to perform circular motion around the axis of the first section column and the second section column by the annular moving assembly, specifically, the first motor 205 is used to drive the traveling gear 208 to rotate. Since the traveling gear 208 is meshed with the spliced ​​half-ring gear 203 and the fixed shell is slidably connected to the annular groove through the slider 207, when the traveling gear 208 rotates, it can move in a circle along the annular gear formed by the two spliced ​​half-ring gears 203. When the traveling gear 208 moves in a circle, it drives the first motor 205 and the fixed shell to move in the same direction and at the same angle. Due to the limiting effect of the slider 207, the connecting plate 209 can always point to the center point of the first annular hinge 101 when following the circular movement of the fixed ring body 206, that is, it is distributed radially.

[0047] Among them, Figure 2 As shown, the first welding assembly includes a first electric telescopic rod 210 fixedly connected to the connecting plate 209, a second motor 211 connected to the output end of the first electric telescopic rod 210, and a first welding gun 212 connected to the output shaft end of the second motor 211. The first electric telescopic rod 210 is used to drive the first welding gun 212 to move along the diameter direction of the second annular hinge 201, and the second motor 211 is used to drive the first welding gun 212 to rotate around the axis of the first electric telescopic rod 210 to a set angle.

[0048] It should be noted that, as mentioned above, when the first welding assembly follows the circumferential movement of the connecting plate 209, the position of the first welding gun 212 can be adjusted by the first electric telescopic rod 210 so that it can weld the radial gap at the intersection of the second column and the first column along the radial direction. When welding along the radial gap, the walking gear 208 is in a stationary state. At this time, the first welding gun 212 can be driven to weld along the radial direction by the extension and contraction of the first electric telescopic rod 210. When welding in a direction perpendicular to the radial direction, it is necessary to change the first welding gun 212 from an arc-shaped moving path to a straight line direction perpendicular to the radial direction during the circular movement by the extension and contraction of the first electric telescopic rod 210. In order to achieve an uninterrupted welding process, it is necessary to adjust the rotation of the first welding gun 212 at the corresponding right-angle change point to adapt to the shape of the second column. At this time, the first welding gun 212 is driven to rotate by the second motor 211, and the rotation angle is adaptively adjusted according to the actual layout angle of the first welding gun 212.

[0049] Among them, Figure 2As shown, the third spliced ​​ring assembly includes a third annular hinge 301, two third semi-ring bodies 302 symmetrically connected on the inner circular surface of the third annular hinge 301, and a third buckle 3010 arranged at the opening of the third annular hinge 301, an L-shaped auxiliary limiting plug 303 is fixedly connected to the third semi-ring body 302, the third annular hinge 301 is fixedly connected to the first annular hinge 101 through a second connecting rod 5, the second connecting rod 5 is arranged in a C shape, and there is a gap between the first electric telescopic rod 210 and the second connecting rod 5.

[0050] It should be noted that, as mentioned above, in order to enable the first section column to be stably set up on the first section column, a third spliced ​​ring assembly and an L-shaped auxiliary limiting plug 303 connected thereto are provided. The opening and closing process of the third spliced ​​ring assembly is the same as the opening and closing process of the first spliced ​​ring assembly and the second spliced ​​ring assembly. When the first spliced ​​ring assembly is sleeved on the second section column, the L-shaped auxiliary limiting plug 303 is inserted into the triangular gap area formed between the two square tubes on the second section column. After the two L-shaped auxiliary limiting plugs 303 are symmetrically in contact with the second section column, a limiting clamping force can be applied to the second section column, thereby preventing it from rotating or tilting. The third spliced ​​ring assembly is coaxially connected to the first spliced ​​ring assembly through the second connecting rod 5, thereby realizing coaxial limiting of the first section column and the second section column.

[0051] Among them, Figure 5 As shown, the in-tube walking assembly includes a hollow tube 601, a plurality of limiting slide rails 602 symmetrically connected to the outer wall of the hollow tube 601, an elastic telescopic rod 603 and a plurality of movable support rods 605 hinged on the limiting slide rail 602, a sliding frame 604 slidably connected to the limiting slide rail 602, two symmetrically arranged mounting plates 607, a plurality of roller shafts 608 movably connected between the two mounting plates 607, a damping belt 609 sleeved on the outside of the plurality of roller shafts 608, a third motor 610 fixedly connected to one of the mounting plates 607, and an elastic support rod 606 hinged between the mounting plate 607 and the sliding frame 604, the other ends of the plurality of movable support rods 605 are respectively hinged to the corresponding mounting plates 607, the other ends of the elastic telescopic rods 603 are fixedly connected to the sliding frame 604, and the output shaft end of the third motor 610 is fixedly connected to one of the roller shafts 608.

[0052] The second welding assembly includes a fourth motor 611 fixedly connected to one end of the hollow tube 601, a second electric telescopic rod 612 connected to the output shaft end of the fourth motor 611, and a second welding gun 613 connected to the output end of the second electric telescopic rod 612. The fourth motor 611 is used to drive the second electric telescopic rod 612 to rotate around the axis of the hollow tube 601 to a set angle, and the second electric telescopic rod 612 is used to drive the second welding gun 613 to move along the diameter direction of the hollow tube 601.

[0053] It should be noted that, as mentioned above, the in-tube walking assembly can carry the second welding assembly to move along the internal space of the second column section. Specifically, the entire in-tube walking assembly is placed from one end of the second column section. At this time, the damping belt 609 sleeved on the roller shaft 608 contacts the inner wall of the second column section. The elastic force generated by the elastic telescopic frame can drive the sliding frame 604 to move along the limiting slide rail 602, so that the elastic force of the elastic telescopic frame provides a thrust for the sliding frame 604, and the sliding frame 604 moves in a direction away from the elastic telescopic frame and pushes the elastic support rod 606 to move. Since the mounting plate 607 is hinged by the movable support rod 605, one end of the elastic support rod 606 can provide a thrust to the mounting plate 607 when following the movement of the sliding frame 604, so that the distance between the mounting plate 607 and the limiting slide rail 602 changes, so that the damping belt 609 can be pressed against the inner wall of the second column section with a set pressure. The symmetrical arrangement of multiple groups of damping belts 609 can make The hollow tube 601 can be located at the central axis of the second column. At this time, the corresponding roller 608 is driven to rotate by the third motor 610. After the roller 608 rotates, it can drive the damping belt 609 to rotate. After the damping belt 609 rotates, it can move along the central axis of the second column, thereby driving the hollow tube and the second welding assembly to move in the same direction and the same distance. When the second welding gun 613 moves to the junction of the second column and the first column, the second electric telescopic rod 613 can be driven by the fourth motor 611. 12 and the second welding gun 613 rotate around the central axis of the hollow tube. Since the gap where the inner wall of the second column section and the first column section meet is an equilateral hexagon, when the fourth motor 611 drives the second electric telescopic rod 612 to rotate, it is necessary to assist the extension and retraction process of the second electric telescopic rod 612 to adjust the moving path of the second welding gun 613, so that it changes from a circular moving path to an equilateral hexagonal moving path, thereby realizing the welding process of the gap at the intersection of the inner wall of the second column section and the first column section.

[0054] The present embodiment is described above, but the present embodiment is not limited to the above-mentioned specific implementation manner. The above-mentioned specific implementation manner is merely illustrative and not restrictive. Under the guidance of the present embodiment, ordinary technicians in this field can also make many forms, which are all within the protection of the present embodiment.
