[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] The following describes the specific embodiments of the present invention in conjunction with the accompanying drawings.

[0020] like Figure 1-4 As shown, a waterproof structure of a color steel plate gutter and overlap seam includes a first connector 1 connected to the color steel plate, a second connector 2 connected to the gutter, and a third connector 4 connected to the steel column. The surface of the first connector 1 connected to the color steel plate is sprayed with a water-based epoxy zinc-rich primer. The water-based epoxy zinc-rich primer increases the corrosion resistance and adhesion of the first connector 1 connected to the color steel plate. At the same time, the water-based epoxy zinc-rich primer is free of VOC and formaldehyde, and has good environmental protection effects.

[0021] The bottom of the second connecting member 2 connected to the gutter and one side of the third connecting member 4 connected to the steel column are connected through a support assembly. The support assembly includes a support frame 3 and a first connecting member. The two ends of the support frame 3 are respectively fixed by the first connecting member and the bottom of the second connecting member 2 connected to the gutter and one side of the third connecting member 4 connected to the steel column. The cavity between the support frame 3, the second connecting member 2 connected to the gutter and the third connecting member 4 connected to the steel column is arranged in a right triangle. The second connecting member 2 connected to the gutter is supported by the support frame 3 to achieve fixation of the second connecting member 2 connected to the gutter.

[0022] The first connector 1 connected to the color steel plate is laid on the top of the third connector 4 connected to the steel column. A waterproof component is provided between the top of the third connector 4 connected to the steel column and the first connector 1 connected to the color steel plate. The waterproof component includes a plug 5. A plurality of plugs 5 are equidistantly installed on the top of the third connector 4 connected to the steel column. A plurality of hidden buckles 6 are equidistantly installed on the top of the third connector 4 connected to the steel column and between the plurality of plugs 5. The top of the third connector 4 connected to the steel column, the plug 5 and the top of the hidden buckle 6 are adhered with butyl tape adhered to the bottom of the first connector 1 connected to the color steel plate. The butyl tape is an existing structure with characteristics such as waterproof sealing and is mainly used for seam processing. A plurality of protrusions matching the size of the hidden buckle 6 are provided on the first connector 1 connected to the color steel plate, and a clamp 7 is provided on the outside of the protruding part. A second connector for tightening the clamp 7 is provided on the upper end of the clamp 7. The first connector and the second connector are both composed of bolts and nuts, and are distinguished by "first" and "second".

[0023] The top of one side of the inner side of the second connector 2 connected to the gutter is provided with a folded edge 201, and the gap between the folded edge 201 and the first connector 1 connected to the color steel plate is sprayed with a high-elasticity caulking agent. The folded edge 201 increases the contact area of ​​the second connector 2 connected to the gutter. The high-elasticity caulking agent is a single-liquid polyurethane caulking agent with flexibility and resilience. It can always seal the gap between the folded edge 201 and the first connector 1 connected to the color steel plate. When in use, the surface of the water-based epoxy zinc-rich primer is sprayed with a high-elasticity weather-resistant topcoat. The high-elasticity weather-resistant topcoat is a non-toxic, environmentally friendly waterproof material that can resist strong acid rain, freeze-thaw, sunlight, bacteria, and stretch more than 25 0% and weather resistance are excellent, and it can also greatly reduce the solar heat absorption of the structure. When in use, you need to first fill the surface cracks and chamfers of the first connector 1 connected to the color steel plate with a single-liquid polyurethane caulking agent, and then apply the water-based epoxy zinc-rich primer to the surface of the first connector 1 connected to the color steel plate by brush, roller or spraying. Then apply high-elasticity weather-resistant topcoat to the surface of the water-based epoxy zinc-rich primer twice by brush, roller or spraying. Before the first application is dry, a non-woven fabric at least 10 cm wide is laid on the lap joint of the first connector 1 connected to the color steel plate. The amount of application for both times is 0.35 kg / ㎡.

[0024] A guide structure 8 for blocking dripping is provided at the upper end of the interior of the second connecting member 2 connected to the gutter. The guide structure 8 consists of a guide plate 801, a connecting rod 802 and a patch 803. The guide plate 801 and the patch 803 are connected by multiple connecting rods 802. One end of the patch 803 is adhered to the middle end of the interior of the second connecting member 2 connected to the gutter through an adhesive layer, and the adhesive layer is used for easy installation.

[0025] In this embodiment, specifically: a sponge strip is installed on the top of the guide plate 801, and the sponge strip is in contact with the bottom end of the edge of the first connecting member 1 connected to the color steel plate. The sponge strip can deform and rebound, and can always be in contact with the first connecting member 1 connected to the color steel plate. The guide plate 801 is arranged at an angle, and a gap is provided between the bottom end of the guide plate 801 and the second connecting member 2 connected to the gutter. The gap provides a flow space for rainwater to prevent rainwater from staying on the guide plate 801. When rainwater drips from the first connecting member 1 connected to the color steel plate, the water flow is guided by the sponge strip to flow along the guide plate 801. When a gap is generated between the first connecting member 1 connected to the color steel plate and the second connecting member 2 connected to the gutter, rainwater can be prevented from continuing to flow along the bottom of the first connecting member 1 connected to the color steel plate into the gap.

[0026] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
