Description

Technical Field

[0001] This utility model relates to the field of prefabricated roofing technology, specifically to a prefabricated roofing reinforcement structure. Background Technology

[0002] In recent years, metal roofing structures have been widely used in large-span building structures such as railway stations, airports, and research plants due to their advantages such as light weight, good thermal insulation, and fast construction speed. In large steel structure roofing projects, in order to reduce the overlap of roofing panels, increase the overall integrity of the roof, and ensure the waterproof and overall compressive strength of the roof, profiled metal roofing panels are widely used because of their light weight, beautiful appearance, and convenient and quick construction. In the installation process of prefabricated roofs, main beams are usually built between two sets of support columns, followed by the installation of multiple sets of secondary beams between the two sets of main beams. The roof is then fixed on the upper side of the secondary beams. Due to the need to consider the overall weight of the building structure, there will be a distance between the two sets of secondary beams.

[0003] In actual use, due to the lack of support on the underside of the roof structure between the two sets of secondary beams, the roof structure between the two sets of secondary beams has weak support. When encountering extreme weather, such as blizzards or hail, this part of the roof is easily damaged, affecting the safety of use.

[0004] Therefore, it is necessary to invent a prefabricated roof reinforcement structure to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a prefabricated roof reinforcement structure to solve the problem that the roof structure located between two sets of secondary beams has weak support and is easily damaged in extreme weather conditions such as blizzards and hail.

Next, the support plate is tightly attached to the lower surface of the roof body. Then, the upper ends of the two sets of threaded rods are connected to the support plate. The support plate, support rods, threaded rods and fasteners work together to support the roof, which facilitates the reinforcement of the roof structure in the existing building without damaging the building components. This effectively improves the structural strength of the roof body and avoids damage to the roof structure caused by severe weather.

[0012] Optionally, the upper side of the fastener is provided with two sets of inverted U-shaped fixing screws, which are fastened to the upper side of the secondary beam body.

[0013] By adopting the above technical solution, during the installation of the fixing screws, the fixing screws are first laid flat and passed through the upper side of the secondary beam body, and then both ends are rotated to the lower side.

[0014] Optionally, two sets of connecting holes are provided on the left and right sides of the upper surface of the fastener, and the two ends of the fixing screw are respectively inserted into the connecting holes on the left and right sides and threaded with nuts.

The upper end of the support rod is rotatably connected to a limit ring, and the upper end of the limit ring is fixedly connected to an adjusting block. The adjusting block is threadedly connected to the threaded rod.

[0017] By adopting the above technical solution, the extension length of the threaded rod can be adjusted by rotating the adjusting block, making it applicable to secondary beams of different spans and improving its adaptability.

[0018] Optionally, the side wall of the support rod is provided with two sets of symmetrically distributed limiting grooves, and the lower end of the threaded rod is fixedly connected with two sets of symmetrically distributed limiting blocks, the limiting blocks being slidably connected to the limiting grooves.

[0032] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0033] This utility model provides, for example Figures 1 to 3 The prefabricated roof reinforcement structure shown includes a main beam body 1, a secondary beam body 11, and a roof body 12. Multiple secondary beam bodies 11 are fixedly connected between the two sets of main beam bodies 1. The roof body 12 is fixed on the upper side of the multiple sets of secondary beam bodies 11. A reinforcement component 2 is provided between the two sets of secondary beam bodies 11. The reinforcement component 2 includes a support plate 3, a first connecting block 31, a support rod 4, a first connecting plate 44, a threaded rod 45, a second connecting plate 48, a fastener 5, a second connecting block 51, and a fixing screw 52. The support plate 3 abuts against the lower surface of the roof body 12, and two sets of first connecting blocks 31 are fixedly connected to the lower surface of the support plate 3.

[0034] The two ends of the secondary beam body 11 are fixed to the two main beam bodies 1 by welding. The roof body 12 is fixed to the upper side of the secondary beam body 11 by connectors (connectors are existing technology and will not be described in detail here). In the process of reinforcing the existing roof body 12, the fasteners 5 are first fixed to the surface of the secondary beam body 11 in sequence. Then the support rods 4 are fixed to the side of the fasteners 5. After the support rods 4 are fixed, the support plate 3 is placed at the center between the two sets of secondary beam bodies 11 and is pressed against the lower surface of the roof body 12. At this time, the support rods 4 on both sides are rotated upward and the upper end of the threaded rod 45 is connected and fixed to the lower surface of the support plate 3. At this time, the support plate 3, support rod 4, threaded rod 45 and fastener 5 work together to support the roof.

[0035] See Figure 2 and Figure 3 The fastener 5 is provided in two sets. The left and right sides of the two sets of fastener 5 are fixedly connected with the second connecting block 51. The fastener 5 is snapped on the lower side of the secondary beam body 11. The upper side of the fastener 5 is provided with two sets of U-shaped fixing screws 52. The fixing screws 52 are snapped on the upper side of the secondary beam body 11. The left and right sides of the upper surface of the fastener 5 are provided with two sets of connecting holes. The two ends of the fixing screws 52 are respectively inserted into the connecting holes on the left and right sides and threaded with nuts.

[0036] Specifically, during the installation of the fastener 5, first, the fixing screws 52 are passed through the secondary beam body 11 and secured to the upper side of the secondary beam body 11 with both ends pointing downwards. Then, the distance between the two sets of fixing screws 52 is adjusted. Next, the fastener 5 is secured to the lower side of the secondary beam body 11, and the two ends of the two sets of fixing screws 52 are inserted into the connecting holes on the left and right sides of the upper end of the fastener 5. The nuts are then threaded onto the two ends of the fixing screws 52, fixing the fixing screws 52 and the fastener 5 to the surface of the secondary beam body 11. In addition, slightly loosening the nuts on both sides allows the fastener 5 and the fixing screws 52 to slide on the surface of the secondary beam body 11, adjusting the position of the fastener 5 and improving the ease of installation.

[0037] See Figure 2 , Figure 4 and Figure 5 The support rod 4 is provided in two sets, and each set of support rods 4 has a threaded rod 45 inside. The upper end of the support rod 4 is rotatably connected to a limit ring 42. The upper end of the limit ring 42 is fixedly connected to an adjusting block 43. The adjusting block 43 is threadedly connected to the threaded rod 45. The side wall of the support rod 4 has two sets of symmetrically distributed limit grooves 41. The lower end of the threaded rod 45 is fixedly connected to two sets of symmetrically distributed limit blocks 46. The limit blocks 46 are slidably connected to the limit grooves 41. The lower end of each set of support rods 4 is fixedly connected to a first connecting plate 44. The first connecting plate 44 is fixedly connected to a second connecting block 31 by bolts. The upper end of each set of threaded rods 45 is fixedly connected to a second connecting plate 48. The second connecting plate 48 is fixedly connected to the first connecting block 31 by bolts.

[0038] In addition, during the installation of the support rod 4, the first connecting plate 44 is first clamped on the side of the second connecting block 51. Then, bolts are passed through the through holes on its surface to fix the first connecting plate 44 and the second connecting block 51. At the same time, the first connecting plate 44 can rotate around the second connecting block 51, thereby allowing the support rod 4 and the threaded rod 45 to rotate. Next, the support plate 3 is placed on the lower side of the support point of the roof body 12. At this time, one side of the support rod 4 is rotated upward to clamp the second connecting plate 48 on the side of the first connecting block 31. Then, bolts are passed through the through holes on its surface to fix the second connecting plate 48 and the first connecting block 31. Then, the other side of the support rod 4 is rotated upward to fix the second connecting plate 48 and the first connecting block 31 at its upper end. At this time, the fixing parts 5, support rod 4, threaded rod 45 and support plate 3 on both sides cooperate to support the roof body 12.

[0039] Meanwhile, when dealing with secondary beam bodies 11 of different spans, rotating the adjusting block 43 clockwise will push the threaded rod 45 outward to accommodate secondary beam bodies 11 with wider spans. Conversely, rotating the adjusting block 43 counterclockwise will retract the threaded rod 45 inward to accommodate secondary beam bodies 11 with smaller spans.

[0040] The working principle of this utility model is as follows: By fixing the support rod 4 and the threaded rod 45 between the support plate 3 and the fixing member 5, the support plate 3, the support rod 4, the threaded rod 45 and the fixing member 5 work together to support the roof body 12, which facilitates the reinforcement of the roof body 12 in the existing building without damaging the building components, effectively improving the structural strength of the roof body 12 and avoiding damage to the roof body 12 caused by severe weather.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
