Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a leak-proof structure for connecting metal roofs and steel structures. Background Technology

[0002] The connection between the metal roof and the steel structure is the core node of the building envelope system. It mainly uses components such as supports, fasteners, and interlocking connectors to firmly connect the metal roof panels with the main steel structure such as steel purlins and steel beams. It must not only bear and transmit the roof's own weight, wind, snow, earthquakes and other external loads, but also coordinate the displacement caused by temperature changes and structural deformation, while taking into account functions such as sealing and wind uplift resistance. The connection between the metal roof and the steel structure is achieved through two core methods: mechanical fixing and structural interlocking. Mechanical fixing uses fasteners such as self-tapping screws and high-strength bolts to penetrate the roof panel and lock it to the steel structure, directly transferring the load and limiting relative displacement. Structural interlocking utilizes the special folded edge structure of the roof panel to interlock with each other, and then uses special supports to fix it to the steel structure to ensure the connection strength.

[0003] The existing connection between the metal roof and the steel structure is a weak point in the building. Long-term exposure to wind, rain, temperature changes, and external loads can easily create gaps, allowing rainwater and snowmelt to seep in. This not only causes indoor ceilings to become damp and fall off, walls to become moldy, and floors to bulge, affecting the living or usage experience, but also damages equipment and raw materials in industrial production and warehousing settings, resulting in direct economic losses. Furthermore, the seeping water can come into contact with the steel structure and cause electrochemical corrosion, leading to rusting, thinning of the cross-section, weakening the structural load-bearing capacity, loosening of joints, deformation of components, and even the risk of roof collapse, significantly shortening the overall service life of the building. To address these issues, a leak-proof structure for the connection between the metal roof and the steel structure is proposed. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a leak-proof structure for the connection between a metal roof and a steel structure, which aims to improve the problem in the existing technology that gaps are easily generated when exposed to wind, rain, temperature changes and external loads for a long time, which directly leads to rainwater and snowmelt seeping in through the gaps.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a leak-proof structure for connecting a metal roof and a steel structure, comprising a metal roof body and a steel structure body. The steel structure body contacts the bottom outer wall of the metal roof body, and the bottom outer wall of the metal roof body contacts a bottom surface. A leak-proof mechanism is provided on the steel structure body, and a limiting mechanism is also provided on the steel structure body. The leak-proof mechanism includes a water-blocking ring, which is fixedly connected to the top outer wall of the metal roof body. The top outer wall of the water-blocking ring contacts a top shield, and a sealing ring is fixedly connected to the bottom outer wall of the top shield. An annular groove is formed on the top outer wall of the water-blocking ring. Multiple rings are fixedly connected to the bottom outer wall of the top shield, and a bolt post is fixedly connected to the bottom outer wall of the top shield. A compression spring contacts the top inner wall of the steel structure body. A hexagonal nut is threaded onto the side outer wall of the bolt post, and a directional mark is fixedly connected to the side outer wall of the hexagonal nut.

[0006] As a further description of the above technical solution: the limiting mechanism includes a positioning groove, which is opened on the inner walls of the top and bottom sides of the main body of the steel structure. The inner walls of the top and bottom sides of the positioning groove are slidably connected to a limiting plate, and the inner wall of the front side of the main body of the steel structure is provided with a derailment groove.

[0007] As a further description of the above technical solution: the outer diameter of the top shield plate is adapted to the outer diameter of the water-blocking wall ring, and the outer side wall of the water-blocking wall ring is fixedly connected with an anti-corrosion layer.

[0008] As a further description of the above technical solution: the sealing ring contacts the inner wall of the side of the annular groove, and the multi-layer ring contacts the inner wall of the side of the annular groove.

[0009] As a further description of the above technical solution: the bolted column penetrates the top inner wall of the main body of the metal roof, and the bolted column penetrates the top inner wall of the main body of the steel structure.

[0010] As a further description of the above technical solution: the compression spring is sleeved on the outer side wall of the bolt post, and the bottom end of the compression spring contacts the top outer wall of the hexagonal nut.

[0011] As a further description of the above technical solution: the front outer wall of the directional mark is fixedly connected with a display coating.

[0012] As a further description of the above technical solution: a wear-resistant pad is fixedly connected to the rear outer wall of the limiting plate, the hexagonal nut contacts the rear outer wall of the limiting plate, and the outer diameter of the derailment groove is adapted to the outer diameter of the limiting plate.

[0013] This utility model has the following beneficial effects: 1. In this utility model, a multi-layer sealing structure is formed by the coordinated cooperation of the water-blocking wall ring, the top cover plate, the sealing ring and the multi-layer ring, which can effectively prevent rainwater from seeping in.

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.

[0018] Reference Figures 1-3This utility model provides an embodiment of a leak-proof structure for the connection between a metal roof and a steel structure, comprising a metal roof body 1 and a steel structure body 2. The steel structure body 2 contacts the bottom outer wall of the metal roof body 1, and the bottom outer wall of the metal roof body 1 contacts a bottom surface 3. A leak-proof mechanism 4 and a limiting mechanism 5 are provided on the steel structure body 2. The leak-proof mechanism 4 includes a water-blocking ring 40, which is fixedly connected to the top outer wall of the metal roof body 1. The top outer wall of the water-blocking ring 40 contacts a top shield 41, which can cover the top opening of the water-blocking ring 40, preventing rainwater from falling directly onto the connection between the water-blocking ring 40 and other components, forming a top protection. The bottom outer wall of the top shield 41 is fixedly connected to... There is a sealing ring 42, which is the core sealing component. It uses its elastic deformation to fill the gaps and enhance the sealing performance between the top shield 41 and the water-retaining ring 40, preventing rainwater from seeping in. The top outer wall of the water-retaining ring 40 has an annular groove 43. The bottom outer wall of the top shield 41 is fixedly connected with a multi-layer ring 44. The bottom outer wall of the top shield 41 is fixedly connected with a bolt post 45. The top inner wall of the steel structure body 2 is in contact with a compression spring 46. The side outer wall of the bolt post 45 is threaded with a hexagonal nut 47. The side outer wall of the hexagonal nut 47 is fixedly connected with a pointing mark 48. The pointing mark 48 is used to indicate the locking position of the hexagonal nut 47, which is convenient to quickly adjust it to a state that is easy to fix with the limiting mechanism 5 during installation, thereby improving installation efficiency and accuracy.

[0019] Reference Figures 1-3 The outer diameter of the top shield 41 is matched with the outer diameter of the water-retaining ring 40. The outer side wall of the water-retaining ring 40 is fixedly connected with an anti-corrosion layer. The anti-corrosion layer can isolate the water-retaining ring 40 from corrosive media such as air and rainwater, slow down its corrosion rate, and extend the service life of the water-retaining ring 40. The sealing ring 42 contacts the inner side wall of the annular groove 43, and the multi-layer ring 44 contacts the inner side wall of the annular groove 43. The bolt post 45 penetrates the inner top wall of the metal roof body 1 and the inner top wall of the steel structure body 2. The compression spring 46 is sleeved on the outer side wall of the bolt post 45, and the bottom end of the compression spring 46 contacts the outer top wall of the hexagonal nut 47. The front outer wall of the directional mark 48 is fixedly connected with a display coating. The display coating can enhance the visual recognition of the directional mark 48, making it convenient for installers to quickly identify its direction in complex construction environments and improving installation and debugging efficiency.

[0020] Reference Figures 1-3The limiting mechanism 5 includes a positioning groove 51, which is formed on the inner walls of the top and bottom sides of the steel structure body 2. A limiting plate 52 is slidably connected to the inner walls of the top and bottom sides of the positioning groove 51. A derailment groove 53 is formed on the inner wall of the front side of the steel structure body 2. A wear-resistant pad is fixedly connected to the outer wall of the rear side of the limiting plate 52. The wear-resistant pad can reduce the frictional wear between the limiting plate 52 and the hexagonal nut 47, extend the service life of both, and enhance the friction after contact, thereby improving the limiting effect. The hexagonal nut 47 contacts the outer wall of the rear side of the limiting plate 52. The outer diameter of the derailment groove 53 is adapted to the outer diameter of the limiting plate 52.

[0021] Working principle: By inserting the bolt column 45 into the interior of the metal roof body 1 and the steel structure body 2, the top cover plate 41 is attached to the water-blocking wall ring 40, and the sealing ring 42 and the multi-layer ring 44 are respectively inserted into the annular groove 43 to form a multi-layer seal, preventing external rainwater or impurities from entering the interior. At the same time, thermal expansion and contraction will occur between the metal roof body 1 and the steel structure body 2 in different seasons. The compression spring 46 continuously pushes the steel structure body 2 and the metal roof body 1 to fit together. Flexible fixation is used to avoid connection gaps. At the same time, the hexagonal nut 47 is prone to self-rotation if it is not limited. When the hexagonal nut 47 rotates to the horizontal position, the limiting plate 52 slides into the positioning groove 51 and contacts the outer surface of the hexagonal nut 47 to limit and fix the hexagonal nut 47 and prevent it from loosening due to self-rotation.
