Description

Technical Field

[0001] The utility model relates to the technical field of metal roof components, in particular to a lightweight metal roof component. Background Art

[0002] Metal roof refers to a roofing form that uses metal sheets as roofing materials and combines the structural layer and the waterproof layer into one. It is widely used in large public buildings, factories, warehouses, residential buildings and other industries. In the use of metal roofs, for the waterproof nodes of steel pipe columns supporting the metal roofs, the existing technology mostly uses rigid waterproof sealing rings for waterproofing assistance. For example, the patent document with application number 202222135355.4 proposes "a high-performance waterproof node of a metal roofing component, including a rigid waterproof sealing ring, a steel pipe column passing through a metal roof, and the rigid waterproof sealing ring is composed of an elastic sealing layer and two completely identical semi-circular rigid shells". After specific implementation, "the rigid waterproof sealing ring is wrapped on the steel pipe column passing through the metal roof through two semi-circular rigid shells embedded with an elastic sealing layer, and is fixed by bolt clamping. No welding is required, and it is easy to install and disassemble, which solves the problem of high welding technology requirements and difficult operation, and at the same time solves the problem of structural expansion and contraction deformation at the welding point of two heterogeneous metals."

[0003] However, the applicant found in actual use that as the use time increases, the elastic sealing ring of the rigid waterproof sealing ring will cause the connection gap to increase due to structural fatigue, which will lead to a gradual decrease in the sealing effect. There is a lack of adaptive adjustment means, and the practicality needs further improvement. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-5 , a lightweight metal roofing component, comprising two symmetrical combined sealing shells 1, wherein the interiors of the two combined sealing shells 1 are both provided with semicircular sealing rings 2, and the two semicircular sealing rings 2 form a sealed space in the middle of the two combined sealing shells 1;

[0024] The front ends and rear ends of the two combined sealing shells 1 are detachably mounted by bolts and nuts, thereby facilitating subsequent assembly operations, and the surface corners of the two combined sealing shells 1 are both set as rounded structures to improve the comfort of assembly and use;

[0025] The surfaces of the two semicircular sealing rings 2 are fixedly connected with conical arc plates 3, and elastic adjustment rods 4 and pressure adjustment components 5 are arranged between the surfaces of the conical arc plates 3 and the corresponding inner wall of the middle part of the combined sealing shell 1, and the bottom of the pressure adjustment component 5 can apply downward top pressure to the conical arc plates 3;

[0026] The elastic adjustment rod 4 includes a guide cylinder 41, a T-shaped rod 42, and a spring 43. One end of the guide cylinder 41 is fixedly connected to the inner wall of the middle part of the combined sealing shell 1, and the T-shaped rod 42 is clamped in the inside of the guide cylinder 41. One end of the T-shaped rod 42 penetrates the end surface structure of the other end of the guide cylinder 41 and extends to the surface of the corresponding conical arc plate 3 for fixed connection. The two ends of the spring 43 are respectively fixedly connected to the surface of the other end of the T-shaped rod 42 and the corresponding inner wall of the combined sealing shell 1. The elastic adjustment rod 4 is used as a yielding condition to create a stable yielding condition for the subsequent adjustment of the connection gap of the semicircular sealing ring 2. In order to further improve the stability of the reciprocating expansion and reset of the spring 43, the end surface of the other end of the T-shaped rod 42 is fixedly connected with a constraint rod, and the constraint rod is clamped in the inside of the spring 43.

[0027] The pressure regulating component 5 includes a long screw 51 and an inner thread sleeve 52. The inner thread sleeve 52 is fixedly sleeved in the corresponding top structure of the combined sealing shell 1. One end of the long screw 51 is threadedly connected to the inside of the inner thread sleeve 52 and can be output toward the bottom of the corresponding conical arc plate 3. The pressure regulating component 5 is used to apply pressure to the conical arc plate 3 and the semicircular sealing ring 2 in a spiral locking manner to improve the sealing between the semicircular sealing ring 2 and the relevant structure. The end of one end of the long screw 51 is fixedly connected to a top pressure ball block 53. The other end of the long screw 51 is provided with an inner hexagonal groove to provide convenient conditions for subsequent disassembly.

[0028] The number of pressure regulating components 5 provided on the two combined sealing shells 1 is no less than three and they are equidistantly distributed, thereby ensuring the balance of pressure regulation.

[0029] Working principle: During use, after the two combined sealing shells 1 and the semicircular sealing rings 2 inside the two combined sealing shells 1 are assembled around the waterproof node of the steel pipe column of the metal roof under the locking assembly of bolts and nuts, the two semicircular sealing rings 2 are used for surrounding sealing;

[0030] Next, the long screw 51 inside the pressure regulating component 5 is turned, and then the top pressure ball block 53 is driven to press down the corresponding conical arc plate 3 under the meshing support of the inner screw sleeve 52, thereby increasing the sealing connection strength of the semicircular sealing ring 2 to the steel pipe column. During the movement of the semicircular sealing ring 2 and the conical arc plate 3, the T-shaped rod 42 moves inside the guide cylinder 41 to provide guidance, and the spring 43 is compressed synchronously;

[0031] When the waterproof node of the steel pipe column shows signs of leakage, the long screw 51 can be further screwed so that the long screw 51, under the meshing support of the inner threaded sleeve 52, drives the top pressure ball block 53 to further press down the corresponding conical arc plate 3, thereby further increasing the sealing connection strength of the semicircular sealing ring 2 to the steel pipe column, thereby eliminating the increase in the connection gap due to the fatigue of the semicircular sealing ring 2 structure.
