Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a beveling device for a multi-sided node plate. Background Technology

[0002] In the field of industrial and civil building construction, steel structures are widely used in current projects. Almost all components, including frame columns (beams), steel lattice columns, steel roof trusses, and tie rods, require gusset plates for connection. These gusset plates are polygonal in size. They are determined in batches on a single steel sheet through calculation and comparison (maximizing area utilization and minimizing waste), using a chalk line drawing method. The required shape and size of each gusset plate are then cut out. Because the edges of each gusset plate need to be beveled for connection to beams and columns, the main purpose of beveling is to ensure complete weld penetration, thereby guaranteeing the strength of the connection.

[0003] The current method for beveling node plates involves placing each plate flat on a top-plane support, and then having workers step on the top surface and use a grinder to grind the bevel (after one side is beveled, the node plate is rotated and moved to the other side). This method poses a safety hazard because the node plates are not stable and may slip and injure workers. Furthermore, the grinding quality is difficult to guarantee, resulting in low labor efficiency and impacting the quality and safety of beveling multi-sided node plates, as well as the smooth progress of construction. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model proposes a device for beveling polygonal node plates, the specific solution of which is as follows:

[0005] A beveling device for a multi-sided node plate includes: a square steel base and a fixing plate. The square steel base is a square groove, which is divided in the middle by a partition. The two sides are a fixing base and a grinding material receiving groove, respectively. The two ends of the partition are in contact with the two short sides of the square steel base. The fixing plate is inclined and fixed to the inner side of the long side of the fixing base. The fixing plate is inclined upward at an angle of 45°-60° with the horizontal direction. The fixing plate is at least 3cm away from the bottom surface of the fixing base, and the horizontal distance between the fixing plate and the inner side of the long side of the fixing base does not exceed 3cm.

[0006] Furthermore, the inner sides of the two short sides of the square steel base are provided with corresponding vertical parallel grooves, and the grooves are matched with the thickness of the partition.

[0007] Furthermore, there are multiple fixing plates. The multiple fixing plates are symmetrical about the central axis of the side they are fixing, and the fixing plates further away from the central axis are closer to the bottom surface.

[0008] Furthermore, the partition plate has multiple through holes near its upper edge, and bolts can be screwed into any of these through holes.

[0009] The beneficial effects of this utility model are as follows: Using this device, the polygonal node plate to be processed can be placed in a fixed base, with its lower end contacting the side furthest from the partition, and its upper end extending outwards. Workers can then grind and bevel the upper end. The device uses fixed clamps to limit its vertical movement, preventing it from tilting during grinding. Splashed material generated during grinding can fall into a grinding material receiving groove or the fixed base, and can be scraped off when it accumulates to a certain amount, preventing burns to workers. Furthermore, multiple fixed clamps of different heights can accommodate node plates of varying lengths. When the node plate is long, its lower end can contact the bottom plate of the fixed base and be limited by the lowest-level fixed clamp. When the node plate is short, its lower end can be contacted by a suitable fixed clamp based on its length, and limited by the upper-level fixed clamp. Simultaneously, the upper end of the node plate extending from the square steel base contacts the partition. Through holes are made in the partition, and bolts are inserted on its left and right sides according to the placement position of the node plate to prevent lateral movement. This device flexibly limits the movement of the node plate in all directions, ensuring safety and stability, and preventing material splashing that could cause injury. It makes the beveling operation of the node plate convenient and quick. The device is reusable and inexpensive, improving construction efficiency and enabling continuous batch grinding. It solves the construction problem of existing node plate beveling with safety hazards, ensuring the smooth implementation of construction progress, quality, and safety, and improving the social and economic benefits of safe construction.

[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0014] A beveling device for a multi-sided node plate includes a square steel base 1 and a fixing plate 2. The square steel base 1 is a square groove, the bottom of which is welded to an operating platform. The square groove is divided in the middle by a partition 3, with a fixing base 11 and a grinding material receiving groove 12 on each side. The two ends of the partition contact the two short sides of the square steel base 1. The fixing plate 2 is inclined and fixed to the inner side of the long side (opposite to the partition) of the fixing base 11. The fixing plate 2 is inclined upward and at least 3 cm away from the bottom surface of the fixing base 11. The horizontal distance between the fixing plate 2 and the inner side of the long side of the fixing base 11 does not exceed 3 cm. The two short sides of the square steel base 1 have corresponding vertical parallel grooves 4. The grooves 4 match the thickness of the partition 3. The partition 3 is inserted and fixed in the square steel base 1 through a pair of corresponding grooves 4. The position of the partition 3 can be adjusted according to the length of the node plate 7 so that the grinding material receiving groove 12 can receive as much splashed material as possible, preventing material from falling and injuring people. There are multiple fixing plates 2, with an angle α of 45°-60° to the horizontal direction. The multiple fixing plates 2 are symmetrical about the central axis of the side they are fixing, and the fixing plates 2 further away from the central axis are closer to the bottom surface. The part of the partition plate 3 near the upper edge has multiple through holes 5. Bolts 6 are screwed into specific through holes according to the width and position of the node plate 7 to limit the node plate 7 in the left and right directions.

[0015] Place the polygonal node plate 7 at an angle inside the fixed base 11, so that the front end of the polygonal node plate 7 is pressed against the lower end of the front inner wall of the fixed base 11 or the lower surface of the middle and rear sections of the fixed plate 2 at a suitable position rests on the upper end of the partition plate 3; use a grinding wheel to grind each side of the polygonal node plate 7 that extends beyond the fixed base 11 to create a bevel (grinding splatter can fall freely into the grinding material receiving groove 12 without burning the operator, and can be scraped out when it accumulates to a certain amount); after the bevel of each extended side is completed, flip the polygonal node plate 7 so that each side that extends into the fixed base 11 becomes the extended end for grinding construction, and complete the bevel construction of the entire node plate 7; take out the polygonal node plate 7 that has been beveled, put in the next polygonal node plate 7 and repeat the above steps until the bevel construction of all polygonal node plates 7 in the project is completed.
