Technical Field

[0001] The invention belongs to the technical field of eaves gutters, and in particular relates to a through-type stainless steel eaves gutter expansion node and an installation method thereof. Background Art

[0002] With the vigorous development of steel structures in large public buildings, metal roof panel systems have developed rapidly and have been widely used. The corresponding drainage systems have also been used more and more widely. As an important part of metal roofs, according to the technical specifications of roofing engineering, the spacing between expansion joints in the gutters should generally not exceed 30m, and their expansion requirements and drainage continuity are crucial.

[0003] Metal materials have the property of thermal expansion and contraction, so for metal eaves gutters, tens of meters long eaves will produce a large expansion and contraction deformation under the action of temperature stress. If not handled properly, it is very easy to cause a series of problems such as eaves cracking and water leakage, which will have a huge adverse impact on the use of the building. Therefore, solving the hidden dangers caused by thermal expansion and contraction of eaves gutters is an urgent link to be solved in the development of metal roof panel systems.

[0014] Furthermore, the spacing between adjacent gutter plates is 40-60 mm, and the spacing between the telescopic nodes on the eaves gutter is 30 mm.

DETAILED DESCRIPTION

[0031] The present invention will be further described below in conjunction with the accompanying drawings.

[0032] A through-type stainless steel eaves gutter expansion and contraction node comprises an expansion and contraction node and a gutter edge plate 1. The expansion and contraction node is arranged between adjacent gutter edge plates 1. The expansion and contraction node comprises a head plate 2 and an expansion and contraction member 3. The gutter edge plates 1 on both sides are both provided with head plates 2. The expansion and contraction member 3 is connected to the adjacent head plates 2. A certain gap is provided between adjacent gutter edge plates 1 to facilitate the expansion and contraction of the expansion and contraction member 3, thereby offsetting the deformation of the roof eaves gutter caused by thermal expansion and contraction, and preventing the eaves gutter from leaking.

[0033] The telescopic member 3 includes a flexible coil 4 and a coil pressure strip 5. The flexible coil 4 is connected to the head plate 2 through the coil pressure strip 5.

The third connecting surface 8 is fixedly connected to the groove edge plate 1. The telescopic member 3 is fixedly connected to the first connecting surface 6. Through the setting of the head plate 2, the length of the flexible coil 4 is increased, which facilitates the deformation of the flexible coil 4 and improves the service life of the flexible coil 4.

[0036] The first connecting surface 6 and the third connecting surface 8 are respectively arranged perpendicular to the second connecting surface 7 . The first connecting surface 6 and the third connecting surface 8 are respectively formed on both sides of the second connecting surface 7 , so as to increase the length of the flexible coil 4 .

[0037] The third connecting surface 8 is arranged toward the edge of the ditch edge plate 1, and a buffer zone 9 is formed between the first connecting surface 6, the second connecting surface 7, and the inner side surface of the ditch edge plate 1. The buffer zone 9 can prevent large-grained stone from flowing over the flexible coil 4, thereby preventing the large-grained stone from causing damage to the flexible coil 4.

[0038] The distance between the edge of the third connecting surface 8 and the edge of the gutter edge plate 1 is 8-12 mm to ensure the length of the flexible coil 4. The distance between the telescopic nodes on the gutter is 30 m.

[0039] The spacing between adjacent groove plates 1 is 40-60 mm.

[0040] After the gutter edge plate 1 is completed, the telescopic member 3 is strictly prohibited from being flattened, that is, the telescopic member 3 is in a contracted state, so that the telescopic member 3 can offset the deformation of the roof gutter caused by thermal expansion and contraction.

[0041] The through-type stainless steel eaves gutter telescopic node is fixedly installed on the eaves pad assembly, and the eaves pad assembly includes an eaves fixing plate 10 and a node fixing plate 11, the node fixing plate 11 is fixedly connected to the eaves fixing plate 10, and a positioning strip 12 is bent and formed on the node fixing plate 11, and the gutter edge plate 1 is positioned and installed by the positioning strip 12, and the eaves fixing plate 10 includes a first eaves plate 13, a second eaves plate 14 and a third eaves plate 15 that are connected to each other, and the first eaves plate 13 and the third eaves plate 15 are fixedly connected with an eaves positioning strip 16, and the eaves pad assembly is positioned and installed by the eaves positioning strip 16, so as to improve the installation accuracy of the eaves pad assembly.

[0042] The installation method of the through-type stainless steel eaves gutter expansion node includes the following steps:

[0043] (i) Fix the eaves pad assembly on the wall, and install the gutter edge plate on the eaves pad assembly;

[0044] (ii) Cut the joints between adjacent ditch edge boards, i.e., cut off 25 mm from each edge of the adjacent ditch edge boards;

[0045] (III) Fix and weld the head plate at the edge of the groove plate, and weld the head plate 10mm inside the cut;

[0046] (iv) Installing flexible coiled material on the head plate;

[0047] (V) Install the coiled material strip on the flexible coiled material and fix it to the head plate. Drill holes and pull rivets at the corners to facilitate riveting of the head plate.

[0048] (6) Apply polyurethane sealant around the groove edge plate and flexible membrane, and strengthen the application of polyurethane sealant at the corner position to improve the overall sealing performance.
