Detailed Description

In order that the above objects, features and advantages of the utility model will be readily understood, a more particular description of the utility model will be rendered by reference to the appended drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model. The present utility model may be embodied in many other forms than described herein and similarly modified by those skilled in the art without departing from the spirit of the utility model, whereby the utility model is not limited to the specific embodiments disclosed below. The technical features of the embodiments of the utility model can be combined correspondingly on the premise of no mutual conflict.

In the description of the present utility model, it will be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element or be indirectly connected with intervening elements present. In contrast, when an element is referred to as being "directly connected" to another element, there are no intervening elements present.

In large-scale factory building, storage commodity circulation and large-scale public building, in order to in time discharge the rainwater that falls at the building roofing, avoid forming roof ponding and lead to the fact the threat to the roof, perhaps lead to the fact water trouble accidents such as rainwater overflow, roof leak, adopt roofing siphon rainwater drainage system to discharge the rainwater fast under the effect of pressure.

The gutter and the downpipe are the main components of the siphon rainwater drainage system. In a preferred embodiment of the present utility model, a butt joint structure is provided at the junction of the down pipe and the gutter in order to improve the tightness and corrosion resistance of the junction of the gutter and the down pipe.

As shown in fig. 1, the docking structure mainly includes a gutter, a downpipe, and a siphon rain hopper 6. Wherein the gutter is used for briefly collecting rainwater gathered from the roof, and then the rainwater gathered in the gutter is discharged through the downspout. The gutter is in a groove shape, and the bottom of the gutter is a gutter bottom plate 1. In order to timely drain the rainwater accumulated in the gutter, a siphon rainwater hopper 6 for enhancing the drainage capacity is arranged between the gutter bottom plate 1 and the downpipe base 2.

In order to improve the tightness of the joint of the gutter base 1 and the downpipe base 2, silicone sealant is adhered to the joint of the downpipe base and the gutter base 1 along the peripheral circumference of the downpipe base 2 to form a sealing layer 3. And the gap between the gutter bottom plate 1 and the downpipe base 2 is completely sealed and closed through the sealing layer 3. This structure is the first waterproof structure provided in this embodiment.

The silicone sealant used in this embodiment is a sealant commonly used in industry. In practical construction, other sealants, such as butyl sealant, may also be selected. Only the sealing glue can be ensured to fill gaps and play a role in sealing, and the sealing glue has the functions of leakage prevention and water prevention.

The sealing layer 3 is coated with corrosion-resistant epoxy asphalt paint to form an anti-corrosion layer 4, and the thickness of the epoxy asphalt paint coated in the embodiment is 2mm, but in practical building construction, the thickness of the anti-corrosion layer is acceptable in the range of 1.5-2.5 mm.

The anticorrosive layer 4 needs to completely cover the position of the sealing layer 3. Thus, the anti-corrosion layer 4 extends outwardly in a horizontal direction, 50mm beyond the periphery of the downspout base 2, so that the anti-corrosion layer 4 completely covers the silicone sealant. In practical construction, the length of the anti-corrosion layer 4 exceeding the periphery of the downspout base 2 is acceptable in the range of 40-60 mm. The inner pipeline of the downpipe base 2 is also required to be coated with corrosion-resistant epoxy asphalt paint to form an anti-corrosion layer.

The anti-corrosion layer 4 is also provided with a double-sided self-adhesive flexible waterproof tape to form a waterproof layer 5. The waterproof layer 5 needs to completely cover the position of the anticorrosive layer 4 to form a closed waterproof. Thus, the waterproof layer 5 extends outwardly in the horizontal direction, beyond the periphery of the downspout base 2 by 100mm. In practical building construction, the length of the waterproof layer 5 exceeding the periphery of the downspout base 2 is acceptable in the range of 90-110 mm. The anti-corrosion layer 4 of the inner pipeline of the downpipe base 2 is also required to be provided with a double-sided self-adhesive flexible waterproof adhesive tape to form a waterproof layer. The waterproof layer 5 extends downwards in the vertical direction, and the length of the waterproof layer 5 in the downpipe base 2 is acceptable within the range of 150-200 mm.

It should be noted that in actual building construction, the waterproof layer 5 may be provided by three-coating one-layer, i.e. a layer of non-woven fabric or mesh cloth with three waterproof layers. The method comprises the following specific steps:

(1) And the anticorrosive layer 4 is coated with a bottom coating in a transverse brushing mode. When brushing, the brushing is uniform, and the missing brushing should be avoided, so that the substrate cannot be seen;

(2) Uniformly paving the cut special polyester cloth on the first waterproof layer finished in the step (1), and then brushing wrinkles with a brush;

(3) Brushing a second layer of waterproof paint, uniformly pushing the special polyester cloth forward on the painted paint, exhausting and compacting by using a roller, and extruding redundant slurry;

(4) After the special polyester cloth coating is dried, the surface coating is coated to finish the setting of the waterproof layer 5.

After the sealing layer 3, the anti-corrosion layer 4 and the waterproof layer 5 are sequentially arranged, waterproof screws sequentially penetrate through the siphon rainwater hopper 6, the waterproof layer 5 and the anti-corrosion layer 4 to be fixedly connected with the downspout base 2, so that the gutter, the siphon rainwater hopper 6 and the downspout are communicated, and rainwater can be conveniently discharged.

According to the anti-seepage and anti-corrosion butt joint structure for the gutter and the gutter, the sealing layer and the waterproof layer are arranged at the butt joint position of the gutter base and the gutter base, so that the sealing waterproof performance of the butt joint position of the gutter and the gutter is effectively improved, the butt joint structure has an anti-seepage and anti-corrosion effect, and the anti-seepage and anti-corrosion butt joint structure can be widely applied to large-scale plants and logistics storage buildings.

The above embodiment is only a preferred embodiment of the present utility model, but it is not intended to limit the present utility model. Various changes and modifications may be made by one of ordinary skill in the pertinent art without departing from the spirit and scope of the present utility model.
