Description

Technical Field

[0001] The present application relates to the technical field of production and processing of cross-column-shaped steel columns, and specifically discloses a support and positioning device for manufacturing cross-column-shaped steel columns. Background Art

[0002] Cross-column steel columns in building steel structures are increasingly used in steel structure projects due to their good bidirectional stress performance, high stability, and strong rigidity, especially in steel-concrete structural columns of high-rise steel structures.

[0003] In the existing production of cross-column steel columns, usually, the cross-column steel columns are composed of an H-shaped steel and two T-shaped steels welded together. In the production process of the cross-column steel columns, the main processing difficulties lie in the assembly accuracy of the H-shaped steel and the T-shaped steel during the assembly and welding of the cross-column steel columns, as well as the control of welding deformation caused by the butt welding of thick plates in the cross-column steel columns and the overall shrinkage stress.

[0004] When the H-shaped steel and the T-shaped steel are welded, the assembly accuracy is controlled by the distance detection element such as the rangefinder to detect the position of the T-shaped steel and the H-shaped steel, and the position of the T-shaped steel or the H-shaped steel is adjusted by the manual control robot arm. When the positions of the T-shaped steel and the H-shaped steel are both within the standard processing range, the T-shaped steel and the H-shaped steel are clamped by the clamp. After the clamping is completed, the positions of the T-shaped steel and the H-shaped steel need to be detected again, and the T-shaped steel and the H-shaped steel need to be fine-tuned again to ensure that the welded cross-column steel column meets the specification requirements. This process involves multiple measurements, position adjustments and clamping of the T-shaped steel and the H-shaped steel, resulting in a long process for fixing the T-shaped steel and the H-shaped steel before welding. The entire welding process of the cross-column steel column is cumbersome and complicated, and the efficiency is low. Therefore, in view of this, the inventor provides a support and positioning device for the production of a cross-column steel column to solve the above problems. Utility Model Content

[0005] The utility model aims to solve the problem that in the traditional cross-column steel column welding forming process, multiple measurements, position adjustments and clamping of T-shaped steel and H-shaped steel are required, resulting in the entire cross-column steel column welding forming process being cumbersome, complicated and inefficient.

[0006] In order to achieve the above-mentioned purpose, the basic scheme of the utility model provides a support and positioning device for manufacturing a cross-column steel column, comprising:

[0007] Supports: There are several supports and they are symmetrically arranged in two rows. Each support is provided with a stepped table for placing the bottom of the H-shaped steel;

[0008] The positioning assembly includes a cross bar and a vertical bar fixed vertically to the middle of the cross bar. The ends of the cross bar are slidably connected to a sliding seat and a first spring is provided between the sliding seat. The sliding seat is provided with a first folding plate that can cooperate with the corner of the H-shaped steel. The top of the vertical bar is provided with a connecting seat. The connecting seat is rotatably connected to a double-headed screw. The double-headed screw is symmetrically threadedly connected to a second folding plate that can cooperate with the corner of the T-shaped steel.

[0009] The principles and effects of this basic solution are:

[0010] Since the assembly accuracy when welding the H-steel and the T-steel mainly depends on the T-steel being located in the middle of the H-steel, the utility model sets a vertical rod, a sliding seat and a first spring so that when the first folding plate cooperates with the corner of the H-steel, the first springs on both sides are compressed synchronously, so that the cross bar and the vertical rod are located in the middle of the H-steel, and then the double-headed screw is turned and rotated to make the second folding plate slide synchronously, so that the T-steel is clamped to the middle of the H-steel. At the same time, in this process, the T-steel also plays a role in limiting and guiding the sliding of the second folding plate.

[0011] Furthermore, the first folding plate is also provided with an ear piece that matches with the end of the H-shaped steel, and the supports at the ends of the H-shaped steel are respectively provided with a fixing seat, and the ear piece is detachably connected with the fixing seat, and the side wall of the vertical rod is provided with a butt column that can abut with the end of the T-shaped steel. By providing the ear piece and the butt column, the ends of the H-shaped steel and the T-shaped steel can be limited and fixed, so as to achieve the effect of the ends of the H-shaped steel and the T-shaped steel being level.

[0012] Furthermore, the vertical rod comprises a fixed rod fixedly connected to the cross rod and a sliding rod slidably connected to the fixed rod, and a second spring is arranged between the fixed rod and the sliding rod. By arranging the fixed rod and the sliding rod, the overall length of the vertical rod can be fine-tuned.

[0013] Furthermore, the abutment columns are all arranged on the side walls of the sliding rod, so that the specifications of the abutment columns are unified and production and processing are convenient.

[0014] Furthermore, the double-headed screw comprises a smooth section rotatably connected to the connecting seat, threaded sections symmetrically arranged on both sides of the smooth section, and screw heads arranged at the ends of the threaded sections. This arrangement facilitates the cooperation between the double-headed screw and the connecting seat.

[0015] Furthermore, the smooth section of the double-headed screw is a stepped shaft, and the maximum diameter part of the smooth section is rotatably connected to the connecting seat, and the side walls on both sides of the connecting seat are detachably connected with end caps for axially limiting the double-headed screw. The double-headed screw is axially limited by the end cap to prevent the double-headed screw from axially sliding during rotation, thereby causing the position of the double-headed screw to deviate, causing the position of the T-shaped steel to deviate.

[0016] Furthermore, the supports in one row are all threadedly connected with fine-tuning bolts, one end of which faces the side wall of the H-shaped steel and abuts against the side wall of the H-shaped steel. Through this arrangement, the clamping of the H-shaped steel can be fine-tuned. BRIEF DESCRIPTION OF THE DRAWINGS
