Description

Technical Field

[0001] This invention relates to the field of steel structure processing technology, specifically to an assembly fixture and assembly method for steel structural components. Background Technology

[0002] Steel structural components, or simply steel structures, are components such as steel beams, steel columns, and steel trusses made of profiles like channel steel, angle steel, and square steel. Steel structural components have extremely wide applications. Due to the requirements of their applications, steel structural components can sometimes be tens of meters or even longer in length. For excessively long steel structural components, they can be segmented or sectioned into unit sections A, such as... Figure 4 As shown, unit section A includes two sets of unit frame plates A1 and A2, corresponding to the upper, lower, left, and right sides. Unit frame plates A1 and A2 are respectively processed from profiles, and then the edges of unit frame plates A1 and A2 are welded together. The assembled unit section A is a square frame-tube steel component. To further improve and ensure the stability and strength of its frame-tube shape, reinforcing rods can be welded between unit frame plates A1 and A2 on opposite sides or between the diagonal longitudinal beams of unit section A. The processing of unit frame plates A1 and A2 of this type of unit section A is relatively easy. The profiles are arranged on a horizontal workbench, ensuring that the longitudinal beams on opposite sides are arranged at the same height and parallel. Given the limited weight of a single longitudinal beam, even if the horizontal reference and table size of the workbench cannot meet the requirements, this can be solved by adjusting the height or adding auxiliary supports outside the workbench area. In other words, the processing of unit frame plates A1 and A2 can be completed in advance; even if there is no suitable large workbench, the processing of unit frame plates A1 and A2 can be completed on site.

[0003] However, the individual unit frame panels A1 and A2, which are processed and formed, weigh several tons and have an area of ​​10 to 20 square meters. 2 If the problem is even larger, then the unit frame plates A1 and A2 are assembled and welded into a frame-tube-shaped unit section A. At the same time, it is necessary to ensure the parallelism and spacing of the unit frame plates on the opposite sides of the unit section A, and the perpendicularity of the unit frame plates on the adjacent sides before welding. There are no readily available tooling equipment and methods in the existing technology.

[0004] Purpose of the invention

[0005] The purpose of this invention is to provide an assembly fixture for steel structural components, suitable for positioning plate-frame shaped steel components to facilitate connection and form frame-tube shaped steel components.

[0006] An assembly fixture for a steel structure component is characterized in that: a horizontally cantilevered support surface is provided on a vertical support, with the support surface arranged at intervals above and below; a limiting device for constraining and limiting the vertical unit frame plate is provided between the upper and lower support surfaces; an adjustment unit is provided at the upper and lower parts of the vertical support to adjust and position the horizontal unit frame plate so that the same side edge of the horizontal unit frame plate shares a vertical plane; and the limiting device on the vertical support can adjust and position the outer frame surface of the vertical unit frame plate and the outer frame surface of the horizontal unit frame plate to share a vertical plane.

[0007] Another object of the present invention is to provide an assembly method for steel structural components, applicable to the positioning of plate-frame shaped steel components for connection to form frame-tube shaped steel components.

[0008] To achieve the above objectives, the technical solution adopted by the present invention is: an assembly method for steel structural components, comprising the following steps:

[0009] A. Provide vertical supports, with vertical supports spaced on the left side forming a left column of vertical supports L, and vertical supports spaced on the right side forming a right column of vertical supports R. Adjust the upper support surface and the lower support surface of the vertical supports forming the left column of vertical supports L and the right column of vertical supports R to the same horizontal plane.

[0010] B. Place the lower horizontal unit frame plate on the lower support surface, and adjust the lower studs so that the stud ends abut against the two outer side plates of the horizontal unit frame plate.

[0011] C. Place the vertical unit frame plate vertically on the lower horizontal unit frame plate, use the limiting rod and pressure plate to constrain the vertical unit frame plate, and adjust the position of the limiting rod and pressure plate so that the outer frame surface of the vertical unit frame plate and the outer frame surface of the horizontal unit frame plate are on the same vertical plane.

[0012] D. Place the upper horizontal unit frame plate on the upper support surface, and adjust the column end of the upper stud so that the outer frame surface of the upper and lower horizontal unit frame plates and the outer frame surface of the vertical unit frame plate are in the same vertical plane.

[0013] E. Weld the horizontal and vertical unit frame plates after positioning.

[0014] In the above scheme, horizontally cantilevered support surfaces are set on the vertical support with upper and lower intervals. The support surfaces of the left column vertical support L and the right column vertical support R are adjusted to be on the same horizontal plane by forming a left column vertical support L and a right column vertical support R from the vertical support. This ensures that the upper and lower unit frame plates placed on the support surfaces can be in a horizontal state. The adjustment units set at the upper and lower parts of the vertical support and the limiting devices on the vertical support can adjust and position the outer frame surface of the vertical unit frame plate and the outer frame surface of the horizontal unit frame plate to be on the same vertical plane, thereby facilitating the connection to form a frame-like steel component.

[0021] Example 1

[0022] like Figure 1 The assembly fixture for a steel structure component shown includes a vertical support 10 with horizontally extended support surfaces 11, which are spaced vertically. A limiting device 13 for constraining and limiting the vertical unit frame plate A2 is provided between the upper and lower support surfaces 11. Adjustment units are provided at the upper and lower parts of the vertical support 10 to adjust and position the same side of the horizontal unit frame plate A1 to share a vertical plane. The limiting device 13 on the vertical support 10 can adjust and position the outer frame surface of the vertical unit frame plate A2 and the outer frame surface of the horizontal unit frame plate A1 to share a vertical plane.

[0023] In the above scheme, the support surfaces 11 arranged at intervals are used to place the upper and lower horizontal unit frame plates A1. The support surfaces 11 are horizontal to ensure that the upper and lower horizontal unit frame plates A1 placed on the support surfaces 11 can be in a horizontal state. Then, the adjustment unit makes the outer frame surfaces of the upper and lower horizontal unit frame plates A1 share the same vertical plane. Then, the limiting device 13 on the vertical bracket 10 adjusts and positions the vertical unit frame plate A2 so that the outer frame surface of the vertical unit frame plate A2 shares the same vertical plane as the outer frame surface of the horizontal unit frame plate A1. This achieves positioning so that the horizontal unit frame plate A1 and the vertical unit frame plate A2 can be connected to form a frame-tube-shaped steel component.

[0024] like Figures 2-4 As shown, in order to place the horizontal unit frame plate A1 and the vertical unit frame plate A2, the vertical supports 10 arranged at intervals on the left side form the left column of vertical supports L, and the vertical supports 10 arranged at intervals on the right side form the right column of vertical supports R. The upper support surface 11 on the vertical supports 10 that form the left column of vertical supports L and the right column of vertical supports R are on the same horizontal plane, ensuring that the frame surfaces of the horizontal unit frame plate A1 placed on the upper support surface 11 and the lower support surface 11 are in a horizontal state that is parallel to each other.

[0025] like Figure 5 , 6 As shown, upper and lower studs 12 are provided above the upper and lower support surfaces 11. The studs 12 and the threaded holes on the vertical bracket 10 form a threaded engagement. The column ends of the upper and lower studs 12 located in the cantilever direction of the support surface 11 can be adjusted to the position of the common vertical plane.

[0026] In the above scheme, the stud 12 and the threaded hole on the vertical bracket 10 form a threaded engagement. The stud can be adjusted in length, allowing the stud end to abut against the two outer surfaces of the horizontal unit frame A1, thus keeping the two outer surfaces of the horizontal unit frame A1 in a common vertical plane position. This allows the position of the lower horizontal unit frame A1 to be adjusted to the desired position and constrained to maintain the adjusted position and orientation.

[0027] Preferably, the support surface 11 is composed of a columnar stud, the front section of which is a cylindrical section, and the threaded section of the rear section of which engages with the horizontal threaded hole on the vertical bracket 10. In the above embodiment, the support surface 11 is composed of a columnar stud, and the threaded section of the rear section of which engages with the horizontal threaded hole on the vertical bracket 10. When the lower horizontal unit frame plate A1 is placed on the lower support surface 11, it facilitates the removal of the upper columnar stud from the vertical bracket 10, or the stud-shaped support surface 11 can be screwed to shorten its overhang, thus avoiding obstructing the placement of the lower horizontal unit frame plate A1.

[0028] Preferably, the stud 12 is arranged parallel to the support surface 11, and the stud end of the stud 12 can completely abut against the two outer side plates of the horizontally placed unit frame plate A1. Since the end of the stud 12 is the working surface, its end can also be designed as a spherical shape. The spherical end can also push against the outer side plates of the horizontally placed unit frame plate A1 to realize the horizontal translation adjustment of the horizontally placed unit frame plate A1.

[0029] like Figure 7 The limiting device 13 shown includes a limiting rod 131 that extends horizontally from the vertical support 10. There is a pull rod 133 parallel to the limiting rod 131 on the side of the limiting rod 131. There is a pressure plate 132 on the pull rod 133. There is a nut 134 on the end section of the pull rod 133. The suspension end of the limiting rod 131 and the pressure plate 132 form a positioning and constraining mechanism to keep the frame surface of the vertical unit frame plate A2 in the vertical plane.

[0030] In the above scheme, the suspension end of the limiting rod 131 is adjusted to a position where it shares a vertical plane with the rod ends of the upper and lower studs 12. Then, the pressure plate 132 is used in conjunction with the limiting rod 131 to constrain the vertical unit frame plate A2. The suspension end of the limiting rod 131 and the pressure plate 132 form a positioning and constraint, ensuring that the outer frame surface of the vertical unit frame plate A2 shares a vertical plane with the outer frame surface of the upper and lower horizontal unit frame plates A1.

[0031] Preferably, in order to better limit and adjust the vertical unit frame plate A2, at least two limiting devices 13 are arranged at parallel intervals in the upper and lower directions. When the vertical unit frame plate A2 is adjusted and limited to the designed position, the initial fixation between the vertical unit frame plate A2 and the lower horizontal unit frame plate A1 can be implemented by partial spot welding.

[0032] To adapt to different working environments, in other words, providing a site that simultaneously meets the requirements for horizontal accuracy and area is extremely difficult. This invention provides the following preferred solution: the bottom of the vertical support 10 is provided with a flat base plate 14. The base plate 14 has an adjusting screw 141 perpendicular to its surface. By adjusting the adjusting screw 141, the base plate 14 can be kept horizontal even on uneven ground. This solution ensures sufficient site area. Even if the horizontal accuracy requirement of the site cannot be met, the assembly of steel components can still be completed using this invention.

[0033] Example 2

[0034] An assembly method for steel structural components includes the following steps:

[0035] A. Provide vertical supports 10, with vertical supports 10 spaced on the left side forming a left column of vertical supports L, and vertical supports 10 spaced on the right side forming a right column of vertical supports R. Adjust the upper support surface 11 on the vertical supports 10 that form the left column of vertical supports L and the right column of vertical supports R to the same horizontal plane.

[0036] B. Place the lower horizontal unit frame plate A1 on the lower support surface 11, and adjust the lower stud 12 so that the stud end of the stud 12 abuts against the two outer side plates of the horizontal unit frame plate A1.

[0037] C. The vertical unit frame plate A2 is vertically arranged on the lower horizontal unit frame plate A1. The vertical unit frame plate A2 is constrained by the cooperation of the limiting rod 131 and the pressure plate 132. The positions of the limiting rod 131 and the pressure plate 132 are adjusted so that the outer frame surface of the vertical unit frame plate A2 and the outer frame surface of the horizontal unit frame plate A1 are located on the same vertical plane.

[0038] D. Place the upper horizontal unit frame plate A1 on the upper support surface 11, and adjust the column end of the upper stud 12 so that the outer frame surfaces of the upper and lower horizontal unit frame plates A1 and the outer frame surfaces of the vertical unit frame plate A2 are vertically aligned.

[0039] E. Weld the horizontal unit frame plate A1 and the vertical unit frame plate A2 after positioning.

[0040] In the above method, the present invention first adjusts the upper support surface 11 of the vertical brackets 10 of the left column vertical bracket L and the right column vertical bracket R to a common horizontal plane and the lower support surface 11 to a common horizontal plane by adjusting the adjusting screw 141 on the plate surface of the base plate 14. This can significantly reduce the ground level requirements of the selected site, and the usable area and space height of the site can meet the requirements. By removing the upper support surface 11 and the limiting device, or by avoiding the placement direction of the upper support surface 11 and the limiting device from the lower horizontal unit frame plate A1, it is ensured that the lower horizontal unit frame plate A1 can be placed on the lower support surface 11 in the most convenient way by going straight up and down.

[0041] Then, by adjusting the lower stud 12 to abut against the two outer side plates of the lower horizontal unit frame plate A1, the lower horizontal unit frame plate A1 is adjusted and fixed. Then, the vertical unit frame plate A2 is vertically arranged on the lower horizontal unit frame plate A1. The limiting rod 131 and the pressure plate 132 are used to constrain the vertical unit frame plate A2 to be in an upright position, so that the outer frame surface of the vertical unit frame plate A2 and the outer frame surface of the horizontal unit frame plate A1 are on the same vertical plane. Finally, the upper horizontal unit frame plate A1 is placed on the upper support surface 11. The column end of the upper stud 12 is adjusted so that the outer frame surfaces of the upper and lower horizontal unit frame plates A1 and the outer frame surfaces of the vertical unit frame plate A2 are on the same vertical plane, so that further processing can be carried out, so that the horizontal unit frame plate A1 and the vertical unit frame plate A2 can be connected to form a frame-tube-shaped steel component. It should be noted that the distance between the upper support surface 11 and the lower support surface 11 is the design spacing. Therefore, the spacing between the upper and lower horizontal unit frame plates A1 is consistent with the design spacing, and at the same time, it matches the dimensions of the vertical unit frame plate A2 between them.

[0042] Preferably, the upper and lower support surfaces 11 of the vertical bracket 10 are leveled by a level, and the upper support surfaces 11 of the left column vertical bracket L and the lower support surfaces 11 of the right column vertical bracket R are adjusted to be on the same horizontal plane by adjusting the adjusting screws 141 on the base plate 14 at the bottom of the vertical bracket 10. This ensures that the vertical bracket 10 in this solution can be arranged on uneven ground.

[0043] During horizontal leveling, the laser beam can be calibrated in the horizontal plane. Using the horizontal plane where the beam calibrates is located as a reference, adjust the upper or lower support surfaces 11 on the left column vertical bracket L and right column vertical bracket R to be on the same horizontal plane. The alignment of the plumb surfaces can also be adjusted using the vertical beam of the laser as a reference. After the horizontal unit frame plate A1 and vertical unit frame plate A2 are placed and their positions adjusted and positioned, the welding process can begin. Once the steel components are processed and separated from the vertical brackets 10, the vertical brackets 10 can be transported to the storage area. Each vertical bracket 10 occupies very little space, making storage convenient.
