Description

Technical Field

[0001] This utility model relates to a reinforcement structure for H-shaped support beams in steel structure factory buildings. Background Technology

[0002] When constructing steel structure workshops, H-beams are required for effective support. Due to the limited length of H-beams, two H-beams need to be spliced ​​together during construction. After splicing, welding is used to fix the two H-beams. The splicing joints are divided into straight splicing, Z-type splicing, and plug splicing. However, this method relies solely on welding to ensure the strength of the connection between the two H-beams. Over time, the weld may crack, making it difficult to guarantee the stability of the connection. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a steel structure factory building H-shaped support beam reinforcement structure to overcome the defects in the prior art.

[0004] To achieve the above objectives, this utility model provides a steel structure factory building H-shaped support beam reinforcement structure, including two butt-jointed H-shaped support beams, with reinforcement components fitted on the two butt-jointed H-shaped support beams for reinforcement at the butt weld joints;

[0005] The reinforcement assembly includes two fasteners, which are fastened together and secured to the H-shaped support beam by bolts.

[0006] The fastener includes a π-mouth plate, and the front and rear sides of the upper and lower ends of the π-mouth plate are respectively provided with concave beams. A socket plate is inserted between the two concave beams at the upper end and the two concave beams at the lower end of the π-mouth plate, and the socket plate rests on the nut end face of the bolt.

[0007] Each of the concave beams has a top plate pin threaded to its end face to secure the socket plate.

[0008] In the steel structure workshop H-shaped support beam reinforcement structure, anti-loosening rods are inserted between the two top plate pins at the upper end and the two top plate pins at the lower end of the π-type plate to prevent the top plate pins from loosening.

[0009] The steel structure workshop H-shaped support beam reinforcement structure includes an anti-loosening rod comprising an inner rod, with an outer insert sleeve fitted at both ends of the inner rod, and a limiting platform at the adjacent ends of the two outer insert sleeves, with a spring connecting the two limiting platforms.

[0011] The steel structure workshop H-shaped support beam reinforcement structure is described above. The insertion plate is a rectangular straight plate with multiple teeth along its bottom length and insertion holes on both sides.

[0012] The steel structure workshop H-shaped support beam reinforcement structure has a π-shaped weld groove on the plate.

[0013] The beneficial effects of this utility model are:

[0014] 1. By setting up a reinforcing component, this utility model can reinforce the weld joint of two H-shaped support beams, which can effectively ensure the stability of the weld joint.

[0032] In order to further understand the structure, features and other objectives of this utility model, the following detailed description is provided in conjunction with the accompanying drawings. The embodiments described in the drawings are only used to illustrate the technical solutions of this utility model and are not intended to limit this utility model.

[0033] Reference Figure 1 , Figure 2 , Figure 3 , Figure 12 , Figure 13 A steel structure factory building H-shaped support beam reinforcement structure includes two butt-jointed H-shaped support beams 1, and a reinforcement component 2 is fitted on the two butt-jointed H-shaped support beams for reinforcement at the butt weld joint.

[0034] Since the splicing joints are divided into straight splicing, Z-type splicing, and plug-in splicing, and the three splicing methods correspond to different weld positions at the splicing joints, the two H-shaped support beams after splicing are effectively clamped by the reinforcement components to ensure the stability of the two H-shaped support beams after connection.

[0035] Reference Figures 4-8 The reinforcement component includes two fasteners 5, which are fastened together and fixed to the H-shaped support beam by bolts 24;

[0036] The fastener includes a π-mouth plate 21, which is designed according to the shape of the H-shaped support beam, being half the shape of the H-shaped support beam. The π-mouth plate can be fastened to one side of the H-shaped support beam. The π-mouth plate has a weld groove 29 that is cut out according to the shape. This weld groove can allow the splicing weld joints to be cleared, preventing the clamping from being affected. At the same time, the middle vertical surface of the π-mouth plate and the horizontal surface that connects to both ends are inclined surfaces 27. This inclined surface can allow the weld joints between the flanges and the web of the H-shaped beam to be cleared, preventing the clamping from being affected and ensuring that the π-mouth plate can be tightly attached to the H-shaped support beam after clamping. The front and rear sides of the upper and lower ends of the π-mouth plate have concave beams 22, which are welded to the π-mouth plate. Insert plates 23 are inserted between the two concave beams at the upper end and the two concave beams at the lower end of the π-mouth plate. The insert plates are abutted against the nut end face of the bolt.

[0037] Each of the concave beams has a top plate pin 25 threadedly connected to its end face to secure the socket plate.

[0038] An anti-loosening rod 26 is inserted between the two top plate pins at the upper end and between the two top plate pins at the lower end of the π-mouth plate to prevent the top plate pins from loosening.

[0039] After the two π-type plates are fixed with bolts, clamping is achieved. The upper and lower ends of the π-type plates are respectively inserted with socket plates. After the socket plates are inserted, their teeth are inserted into the bolt thread, and their backs are attached to the end face of the bolt nut. The two ends of the socket plates are located in the concave beam and are connected to the top plate pins by threads. The top plate pins push against the two ends of the socket plates, so that the socket plates can be stably attached to the end face of the nut to prevent the nut from loosening.

[0040] Reference Figure 9 The locking rod includes an inner rod 263, with an outer insertion tube 261 sleeved at both ends of the inner rod. The inner rod and the outer insertion tube are slidably fitted. The inner rod is a cylindrical rod. The adjacent ends of the two outer insertion tubes have a limiting platform 262. A spring 264 is connected between the two limiting platforms.

[0041] After the top plate screws are installed, the locking rods need to be inserted into the through holes at the frustums of the two top plate screws. This will link the two top plate screws together and prevent them from loosening.

[0042] When insertion is needed, hold the limiting platform with both hands, then slide the two external insertion tubes towards the middle. After sliding, align the external insertion tubes at both ends of the device with the through hole of the truncated cone, then release the external insertion tubes. Under the action of the spring, they will be inserted into the through hole.

[0043] Reference Figure 10The top plate screw includes a frustum 254, on which a screw section 252 is fixed. The screw section has an external thread. A large screw hole 30 is opened at the end of the concave beam away from the π-mouth plate. An internal thread that matches the external thread of the screw section is opened in the large screw hole. The diameter of the screw section is twice the diameter of the straight rod section. A straight rod section 251 is fixed at the end of the screw section. A through hole 253 is opened on the side wall of the frustum for the insertion of the anti-loosening rod.

[0044] After the socket plate is inserted, the top plate screw needs to be installed. The end face of the concave beam that contacts the π socket plate has a small through hole 31, and the small through hole penetrates the π socket plate. The diameter of the insertion hole on the socket plate is equal to the diameter of the small through hole. First, insert the top plate screw through the large screw hole and then through the insertion hole of the socket plate into the small through hole of the concave beam. Then continue to insert until the screw section contacts the large screw hole. Then tighten the top plate screw to make the screw section threadedly connected to the large screw hole until the end of the screw section hits the socket plate. Tighten the socket plate so that the socket plate can always stably contact the end face of the bolt nut.

[0045] Reference Figure 11 The socket plate is a rectangular straight plate with multiple teeth 232 opened along its length at the bottom and insertion holes 231 opened on both sides.

[0046] Work distance: During use, after the two H-shaped supports are spliced ​​and welded together, fasten the fasteners to the splice joints of the two H-shaped support beams. At this time, the weld groove should allow the splice weld joint 4 to be cleared to prevent the clamping from being affected. At the same time, the middle vertical surface of the π-plate and the horizontal surface where the two ends meet form an inclined plane 27. This inclined plane can allow the weld joint 3 between the flange and web of the H-shaped beam to be cleared to prevent the clamping from being affected. Ensure that the π-plate can be tightly attached to the H-shaped support beam after clamping. Multiple fixing holes 28 are opened at the bolt connection points at the upper and lower ends of each π-plate for bolts to pass through. After the two fasteners are fastened together and fixed with bolts, install the insert plate. Insert plates are inserted at the upper and lower ends of the π-plate. After the insert plate is inserted, its teeth are inserted into the bolt thread, and its back is attached to the nut end face of the bolt. The two ends of the insert plate are in the concave beam. First, install the π-plate... After inserting the socket plate at the top of the plate, install the top plate screw at the top. First, insert the top plate screw through the large screw hole and then through the socket hole of the socket plate into the small through hole of the concave beam. Continue to insert until the screw section contacts the large screw hole, then tighten the top plate screw to make the screw section threadedly connected to the large screw hole until the end of the screw section hits the socket plate. Tighten the socket plate so that it can always stably contact the end face of the bolt nut. Then install the socket plate at the bottom of the π-plate. After all are installed, the anti-loosening rod needs to be installed. Hold the limiting platform of the outer tube with both hands, and then slide the two outer tubes towards the middle. After sliding, align the outer tubes at both ends of the device with the through hole of the truncated cone of the top plate screw, and then release the outer tubes. Under the action of the spring, they will be inserted into the through hole. This will link the two top plate screws together and prevent the top plate screws from loosening.
