Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel structure technology, specifically a steel structure bridge reinforcement device. Background Technology
[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. The structure mainly consists of steel beams, steel columns, steel trusses, and other components made of shaped steel and steel plates, and employs rust removal and prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. The various components are typically connected by welds, bolts, or rivets. Due to their light weight and simple construction, they are widely used in large factories, stadiums, high-rise buildings, bridges, and other fields. Steel structures are prone to corrosion; generally, steel structures require rust removal, galvanizing, or painting, and regular maintenance.
[0003] With the continuous advancement of infrastructure construction in my country, steel structure bridges have been widely used due to their advantages such as convenient installation and short construction period. Steel structure bridges use node connection to connect various components, and the connection strength of the node device directly affects the safety and service life of the steel structure bridge.
[0004] Existing bridge joints are typically fixed with bolts during installation, lacking reinforcement devices. Furthermore, in addition to right-angle connections, existing joints also include inclined connections. Existing reinforcement devices lack sufficient adjustment capabilities and are not suitable for inclined joints of different angles. Therefore, we propose a steel structure bridge reinforcement device to solve the above problems. Utility Model Content

[0010] Preferably, a second nut is fitted onto the surface of the screw, and the screw is threadedly connected to the second nut to facilitate fixing and reinforcing the support rod.
[0011] Preferably, the reinforcing support rod is the same size as the reinforcing main rod, and the reinforcing support rod and the reinforcing main rod are arranged overlappingly to facilitate the transportation and storage of the device.
[0012] Preferably, the reinforcing support rod has a groove inside that matches the gear plate, and a through hole inside that matches the screw. The gear plate is inserted inside the reinforcing support rod to facilitate angle adjustment of the reinforcing support rod.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] (1) The device is equipped with bolts and a first nut, which, together with the connecting rod and the gear plate, enable the device to reinforce the nodes of steel structure bridges. By passing the fixing bolts through the main reinforcement rod and the reinforcement support rod and inserting them on both sides of the node, the main reinforcement rod and the reinforcement support rod can reinforce the node, making the node more stable and improving the working efficiency of the device.
[0015] (2) The device is equipped with a connecting rod and a toothed disc, which, together with a screw and a second nut, allow the device to be adjusted according to the inclination angle of the bridge node.

[0023] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-5 An embodiment of this utility model provides a steel structure bridge reinforcement device, including a reinforcement main rod 1, an adjustment mechanism 2 provided on the surface of the reinforcement main rod 1, the adjustment mechanism 2 including a bolt 210, the bolt 210 being inserted into the interior of the reinforcement main rod 1, a first nut 220 being sleeved on the surface of the bolt 210, a connecting rod 230 being inserted into the interior of the reinforcement main rod 1, and a gear plate 240 being fixed on the surface of the connecting rod 230, a screw 250 being fixed on the surface of the gear plate 240, a second nut 260 being sleeved on the surface of the screw 250, and a reinforcement support rod 270 being sleeved on the surface of the screw 250;
[0025] The main reinforcing rod 1 and the reinforcing support rod 270 have equally spaced circular through holes inside. The main reinforcing rod 1 and the reinforcing support rod 270 are strip-shaped structures. Fixing bolts can be inserted through the circular through holes to facilitate fixing the device to the connection node. The strip-shaped structure is more in line with the strip shape of the steel structure and will not protrude from the steel structure.
[0026] Bolt 210 passes through the reinforcing main rod 1 and the connecting rod 230 and is inserted into the first nut 220. The first nut 220 and bolt 210 are threaded together, which can fix the connecting rod 230 and the reinforcing main rod 1, making the device easy to assemble. The connecting rod 230 has a square structure and is inserted into the reinforcing main rod 1. The square structure of the connecting rod 230 is inserted into the reinforcing main rod 1 and fixed by bolt 210 and first nut 220, so that the gear plate 240 can be fixed and cannot rotate, making the gear plate 240 more stable and facilitating the support of the connection node.
[0027] The reinforcing support rod 270 has a groove inside that matches the gear plate 240, and a through hole inside that matches the screw 250. The gear plate 240 is inserted into the reinforcing support rod 270. A second nut 260 is fitted on the surface of the screw 250, and the screw 250 and the second nut 260 are threaded together. The gear plate 240 is inserted into the reinforcing support rod 270 at different rotation angles, which can adjust the angle between the reinforcing main rod 1 and the reinforcing support rod 270. The second nut 260 is rotated to press the reinforcing support rod 270, which can fix the reinforcing support rod 270 and facilitate the adjustment of the device according to different tilt angles.
[0028] The reinforcing support rod 270 is the same size as the reinforcing main rod 1. The reinforcing support rod 270 and the reinforcing main rod 1 are overlapped, making the device more regular in shape when not in use, and taking up less space, which is convenient for transportation and storage.
[0029] Working principle: When the device is working, loosen the second nut 260, then pull out the reinforcing rod 270 to separate it from the gear plate 240. Figure 3 As shown, to adjust the angle of the reinforcing node as needed, rotate the reinforcing rod 270, then insert the gear plate 240 into the reinforcing rod 270, and finally tighten the second nut 260 onto the screw 250. Figure 5 As shown, the rotation angles of the reinforcing support rod 270 and the reinforcing main rod 1 are fixed, and then the fixing bolts are inserted through the circular through holes on the reinforcing main rod 1 and the reinforcing support rod 270 and fixed on both sides of the node that needs to be reinforced, so that the device can reinforce the connection node of the steel structure bridge. The above is the complete working principle of this utility model.
