Description

Technical Field

[0001] This utility model relates to the field of steel truss docking technology, and in particular to a steel truss docking positioning device. Background Technology

[0002] Steel truss construction is a widely used construction method for large-span building structures, and its high strength, lightweight, and modular characteristics have made it an important technology in modern engineering. Steel trusses are mainly composed of steel pipes, shaped steel sections, or steel plates, connected by welding or bolting to form stable triangular or rectangular units, effectively distributing loads and improving the overall structural stiffness and load-bearing capacity. The construction process mainly includes design planning, material prefabrication, on-site assembly, and hoisting. In the design phase, the truss form needs to be determined based on load requirements, span, and usage environment. In the material prefabrication phase, the members are cut, drilled, and treated with anti-corrosion measures in the factory to ensure accuracy and quality. During on-site construction, the truss units are assembled into a whole through ground assembly or segmented hoisting, supplemented with temporary supports to ensure stability, and finally fixed by welding or high-strength bolts.

[0003] A search revealed that patent CN216912667U discloses a high-altitude docking positioning device for steel truss chords. This device increases the contact area between the chord positioning adjustment bolt and the chord's curved surface by setting an arc-shaped abutment plate on the abutment end, thereby improving docking reliability, reducing displacement or force-induced movement during welding, and enhancing docking positioning accuracy and welding reliability. However, this device can only weld and fix two trusses through the docking positioning welding holes on the boat-shaped limiter. The operating space for welding through these holes is too small, making welding inconvenient. Furthermore, the device can only position trusses that are docked in a straight line; it is unsuitable for perpendicular docking of two trusses. Therefore, further improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a steel truss docking and positioning device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a steel truss docking and positioning device, comprising two fixing components, each of which includes an arc-shaped plate and an L-shaped plate. The arc-shaped plate is fixedly connected to the L-shaped plate on its open side, and the arc-shaped plate and the L-shaped plate are integral structures. The adjacent sides of the L-shaped plates of the two fixing components are fixed with end plates. The surfaces of the two end plates are respectively fixed with a first connecting rod and a second connecting rod. A sleeve is slidably sleeved on the surface of the first connecting rod. The sidewall and top of the sleeve are fixed with connecting sleeves for engaging the first connecting rod. A pressing component is threadedly connected to the middle of the L-shaped plate.

[0006] Furthermore, the extrusion member includes a screw that passes through the L-shaped plate and is threadedly connected to the L-shaped plate. One end of the screw near the arc-shaped plate is rotatably connected to a V-shaped plate via a bearing, and the other end of the screw is fixed with a knob.

[0007] Furthermore, a guide rod is fixed to the surface of the V-shaped plate, and the guide rod passes through the L-shaped plate and is slidably connected to the L-shaped plate.

[0008] Furthermore, a rubber pad is fixed to the surface of the V-shaped plate.

[0009] Furthermore, the bottom sidewall of the sleeve is connected by a fastening bolt through a thread, and one end of the fastening bolt inside the sleeve is in contact with the surface of the first connecting rod.

[0010] Furthermore, a groove is provided on the side wall of one end of the second connecting rod inserted into the connecting sleeve, a spring is fixed to the inner wall of the groove, a locking rod is fixed to the other end of the spring, and the locking rod is slidably connected to the groove. A locking hole is provided on the side wall of the connecting sleeve for locking the locking rod.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-5 As shown, a steel truss docking and positioning device is disclosed, comprising two fixing members 1, each fixing member 1 including an arc-shaped plate 101 and an L-shaped plate 102. The arc-shaped plate 101 is fixedly connected to the L-shaped plate 102 on one open side, and the arc-shaped plate 101 and the L-shaped plate 102 are integral structures. An end plate 103 is fixed to the adjacent side ends of the L-shaped plate 102 of the two fixing members 1. A first connecting rod 3 and a second connecting rod 4 are respectively fixed to the surface of the two end plates 103. A sleeve 5 is slidably sleeved on the surface of the first connecting rod 3. A connecting sleeve 6 for engaging the first connecting rod 3 is fixed to the side wall and top of the sleeve 5. An extrusion member 2 is threadedly connected to the middle of the L-shaped plate 102.

[0024] The extrusion component 2 includes a screw 21 that passes through the L-shaped plate 102 and is threadedly connected to the L-shaped plate 102. One end of the screw 21 near the arc plate 101 is rotatably connected to a V-shaped plate 22 via a bearing, and the other end of the screw 21 is fixed with a knob.

[0025] When fixing the truss with fastener 1, the opening between L-shaped plate 102 and arc plate 101 is passed through the truss so that fastener 1 is fitted onto the surface of the truss. Then, the knob on screw 21 is rotated to move V-shaped plate 22. V-shaped plate 22 is used to press the truss to fix fastener 1 to the surface of the truss.

[0026] A guide rod 23 is fixed to the surface of the V-shaped plate 22. The guide rod 23 passes through the L-shaped plate 102 and is slidably connected to the L-shaped plate 102.

[0027] The guide rod 23 guides the movement of the V-shaped plate 22, preventing the screw 21 from rotating and causing the V-shaped plate 22 to rotate.

[0028] A rubber pad is fixed to the surface of the V-shaped plate 22.

[0029] By setting a rubber pad on the surface of the V-shaped plate 22, the friction between the V-shaped plate 22 and the truss can be increased, making the connection between the V-shaped plate 22 and the truss more stable and firm.

[0030] The bottom sidewall of the sleeve 5 is penetrated and connected by a fastening bolt 51 via a threaded rotation. One end of the fastening bolt 51 located inside the sleeve 5 is in contact with the surface of the first connecting rod 3.

[0031] The sleeve 5 can slide along the surface of the first connecting rod 3, thereby adjusting the distance between the two fixing parts 1. When actually docking and positioning the truss, the position of the two fixing parts 1 can be flexibly adjusted to improve the flexibility of use. After adjustment, tighten the fastening bolt 51 to press and fix the first connecting rod 3.

[0032] The second connecting rod 4 is inserted into the side wall of the connecting sleeve 6, which has a groove 41. A spring 42 is fixed to the inner wall of the groove 41. A locking rod 43 is fixed to the other end of the spring 42, and the locking rod 43 is slidably connected to the groove 41. The side wall of the connecting sleeve 6 has a locking hole 61 for locking the locking rod 43.

[0033] In this embodiment, the connection between the second connecting rod 4 and the sleeve 5 is fixed by the connecting sleeve 6. When the second connecting rod 4 is inserted into the corresponding connecting sleeve 6, the clamping rod 43 is first squeezed back into the groove 41, so that the spring 42 is compressed. Then the second connecting rod 4 is inserted into the connecting sleeve 6. After the second connecting rod 4 is fully inserted, the spring 42 squeezes the clamping rod 43 to pop out from the groove 41. The clamping rod 43 will then be locked into the locking hole 61, thus fixing the second connecting rod 4 and the connecting sleeve 6, and thus achieving a fixed connection between the second connecting rod 4 and the sleeve 5.

[0034] During disassembly, squeezing the clamp 43 separates it from the clamp hole 61, allowing the second connecting rod 4 to be pulled out of the connecting sleeve 6. By fixing the second connecting rod 4 in two different positions within the connecting sleeve 6, the two fixing members 1 can be positioned in a straight line or in a vertical direction, thus enabling the positioning of trusses with different docking methods.

[0035] Working principle: First, according to the truss docking method (vertical or straight), fix the second connecting rod 4 in the corresponding connecting sleeve 6. Then, put the two fixing parts 1 on the two truss surfaces respectively, and then use the pressing part 2 to press and fix the truss. The two fixing parts 1 are fixed on the two truss surfaces respectively to realize the docking positioning of the truss. At this time, the docking position of the two trusses is completely exposed, which is more conducive to welding operation.

[0036] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
