Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of overflow gutters, in particular to a metal slope roof overflow gutter. BACKGROUND

[0002] In the design of building engineering, curved or sloping metal roofs are very common, which can coordinate the deformation of large-span steel structures and reduce the load of the roof. Overflow gutters are usually provided at the edge of the metal slope roof for drainage. Overflow gutters are channels on the roof of a building used to collect and discharge rainwater in an organized manner. When the rainwater exceeds the capacity of the gutter, the excess rainwater will be discharged through the overflow facility to prevent rainwater from overflowing the gutter. Overflow gutters are usually connected to a rainwater pipe system to ensure that rainwater can be smoothly discharged and to avoid water accumulation.

[0003] The patent with publication number CN207079827U discloses a metal slope roof overflow gutter, which comprises a high roof, a low roof, a gutter groove located between the high roof and the low roof, and a stainless steel gutter. The gutter groove comprises a horizontal segment bottom wall, a low roof side wall, and a high roof side wall. The stainless steel gutter is in line with the gutter groove. A bending segment is provided on the low roof side wall top surface of the low roof side wall of the stainless steel gutter. The bending segment extends to the low roof slope direction and is folded. The advantages of the present application are as follows: the product structure is reasonable. When the water in the gutter flows to the low roof after overflowing the gutter, it is then discharged to the outside of the roof. The overflow requirement for roof drainage in extreme weather is met.

[0004] With regard to the above-mentioned related technology, the inventors believe that a tens of meters long gutter will produce a large amount of expansion and contraction deformation under the action of temperature stress. Therefore, expansion joints are usually provided in the gutter according to requirements. However, if the expansion joints are not properly treated, water leakage will occur from the expansion joints when the gutter is full of water and overflowing. For example, a rubber buffer material is usually provided in the deformation joint of the stainless steel gutter to seal it. However, the excessive compression of the deformation joint can easily cause the rubber buffer material to lose its elasticity, thereby reducing the sealing effect of the expansion joint. To address this problem, the present application provides a metal slope roof overflow gutter. Utility model content

[0012] Preferably, the bottom of the connecting seat is provided with a plug hole, the two ends of the limiting rod are respectively inserted into the plug holes of the two adjacent connecting seats in a matched mode, the two ends of the limiting rod are provided with fixing holes, the outer wall of the connecting seat is fixedly provided with a tension spring, one end of the tension spring is fixedly provided with a pull plate, the outer wall of the tension spring and the pull plate is coated with rust-proof paint, and the connecting mechanism comprises a fixing rod fixedly arranged on the pull plate close to one end of the tension spring, and one end of the fixing rod penetrates through the connecting seat and is inserted into the fixing hole in a matched mode.

[0013] By adopting the above technical scheme, the fixing rod can be quickly inserted into the fixing hole under the tension of the tension spring, so that the two ends of the limiting rod can be quickly installed and fixed.

[0014] Preferably, one end of the connecting seat is provided with a positioning hole, and a rotating rod for being screwed into the matched positioning hole when the fixing rod is pulled away from the fixing hole is rotatably arranged on the side of the pull plate away from the tension spring.

[0017] 1. The stretchable part is used to seal the deformation joint of the stainless steel gutter, and the limiting rod can limit the two ends of the deformation joint, which can effectively prevent the deformation joint from being excessively extruded, thereby ensuring the effective use of the stretchable part in the deformation joint, preventing water leakage at the deformation joint, and making the overflow gutter have reasonable overall structure, intuitive inspection, firmness, durability, easy maintenance, and easy popularization in metal roof construction.
