Description

TECHNICAL FIELD

[0001] The present application relates to the field of metal roof water collection point structure, and particularly relates to a connecting structure for a metal roof water collection point. BACKGROUND

[0002] The construction technology level of large-span space steel structure is an important symbol to measure the building technology level of a country or region, and is also a manifestation of the comprehensive national power. In recent years, with the development of traffic, economy and population, the construction of high-speed rail station buildings is also more and more extensive, and the pursuit of high-speed rail station building construction gradually changes to large-span, large-space and unique and beautiful appearance.

[0003] As an outer envelope system of building structure, the metal roof system plays a safe role of envelope structure, and its safety mainly involves waterproofing, fire resistance, wind resistance, durability and the like of the roof system. The waterproofing performance of the metal roof depends on the rationality of waterproofing measures on one hand, and depends on the rationality of drainage measures on the other hand.

[0004] Organized drainage refers to a drainage mode that rainwater on the roof is organized to be drained to the ground or underground pipe trench through the gutter, rainwater inlet, rainwater pipe and the like of the drainage system. This drainage mode has a relatively complex structure and relatively high cost, but reduces the adverse effects of rainwater on the building, and thus is widely applied in building engineering. In the traditional water collection point of metal roof, leakage is most likely to occur due to rainwater accumulation, which causes rainwater to flow back to the insulation layer of the roof and causes damage to the building. Therefore, how to develop a new connecting structure for the water collection point of metal roof becomes a problem to be solved by the technical personnel in the field. SUMMARY

[0005] The present application aims to provide a connecting structure for a metal roof water collection point, and solve the problem that in the traditional water collection point of metal roof, leakage is most likely to occur due to rainwater accumulation, which causes rainwater to flow back to the insulation layer of the roof and causes damage to the building.

[0006] To solve the above technical problems, the present application adopts the following technical scheme:

[0007] The application discloses a connecting structure for a metal roof water collecting point.

[0008] Further, the lower surface of the gutter is filled with butyl tape between the upper surface of the support square tube.

[0009] Further, the stainless steel pressing sheet, the water shedding plate and the lengthwise fixing piece are connected through bolts.

[0010] Further, the purlin structure comprises a main purlin and a secondary purlin, the main purlin is arranged perpendicularly to the extension direction of the gutter, and the lower end of the center line of the extension direction of the gutter is provided with the secondary purlin.

[0011] Further, the metal roof structure comprises, from bottom to top, a roof bottom layer, a sound absorption layer, an air isolation layer, a heat preservation layer, a waterproof layer, an isolation layer and a metal roof top layer.

[0012] Further, the roof bottom layer comprises a roof bottom plate, the roof bottom plate is arranged above the purlin structure, a H-shaped support is arranged above the roof bottom plate, the H-shaped support and the secondary purlin are located on the same straight line, and the secondary purlin, the roof bottom plate and the H-shaped support are anchored through hexagonal head screws; the roof bottom plate is arranged in an overall manner, and the edge of the roof bottom plate is close to the support square tube.

[0013] Further, the sound absorption layer comprises superfine glass fiber cotton and a H-shaped support, the H-shaped support is located directly above the secondary purlin, and the upper end of the roof bottom plate is paved with the superfine glass fiber cotton; the air isolation layer comprises an air isolation plastic veneer, and the air isolation plastic veneer is paved on the superfine glass fiber cotton; the air isolation plastic veneer is arranged in an overall manner, and the edge of the air isolation plastic veneer is close to the support square tube.

[0014] Furthermore, the insulation layer includes a U-shaped purlin and insulation cotton. The U-shaped purlin is positioned directly above the U-shaped support and is fixedly connected to the U-shaped support by hexagonal head screws. The insulation cotton is laid on top of the air-tight plastic sheeting.

[0015] Furthermore, the waterproof layer includes a waterproof membrane, which is laid on top of the insulation layer and is installed as a whole; the isolation layer includes T-shaped brackets and insulation cotton, the lower surface of the T-shaped brackets is fixed to the purlins by hexagonal head screws, the top of the T-shaped brackets extends into the top layer of the metal roof, and the height of the T-shaped brackets is equal to the sum of the thickness of the isolation layer and the top layer of the metal roof; insulation cotton is laid on top of the waterproof membrane.

[0016] Furthermore, the top layer of the metal roof includes metal roof panels, with metal roof panels laid on both sides of the water collection structure. The metal roof panels are wavy, with the inner layer of the crests locked into the upper part of the T-shaped brackets for edge locking and fixation. Hexagonal head screws are used to connect the metal roof panels and the T-shaped brackets. Wind-resistant clips are provided on the outer layer of the crests of the metal roof panels through connecting bolts. Wind-resistant pressure plates are laid on the upper surface of the wind-resistant clips, and the wind-resistant pressure plates are anchored to the upper part of the wind-resistant clips through bolts. Foam plugs are provided on the inner layer of the crests of the metal roof panels at the end near the water collection structure.

[0017] Compared with the prior art, the beneficial technical effects of the present invention are as follows:

[0018] This invention provides a connection structure for water collection points on metal roofs. By adding a drip edge with a sharp angle at the bottom and a stainless steel pressure plate to the side of the gutter, it effectively solves the problem of rainwater seepage along the edge of the drip edge. The gutter and supporting square tube of this invention are seamlessly integrated with the purlin structure, resulting in higher structural strength. The roof structure of this invention connects secondary purlins, U-shaped supports, U-shaped purlins, and T-shaped brackets together with hexagonal head screws to form the central main connection section. The bottom secondary purlins and main purlins are then connected together, and the upper metal roof panel and T-shaped brackets are connected together, achieving a connection between the top layer of the metal roof and the purlin structure, greatly increasing the roof structure's resistance to strong winds. In summary, the connection structure for water collection points of metal roofs in this invention is ingeniously designed and highly waterproof. It effectively solves the problem that water collection points on traditional metal roofs are prone to leakage due to rainwater accumulation, causing rainwater to flow back into the roof insulation layer and damage the building.
