In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0022] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] Please refer to Figure 1-4 As shown, a drainage ditch structure for a house roof comprises a drainage beam 1 and a waterproof pad 2 pressed on the back plate of the drainage beam 1, the drainage beam 1 comprises a top edge beam frame 11, the top edge beam frame 11 is made of galvanized steel material, and multiple groups of expansion bolts 3 penetrating the waterproof pad 2 are arranged at the upper and lower ends of the frame of the top edge beam frame 11, the combination of the drainage beam 1 and the waterproof pad 2 is integrally installed at the roof position of the house by fastening with the bolts of the expansion bolts 3, the waterproof pad 2 is elastically squeezed by the bolts of the expansion bolts 3, and is tightly installed on the wall of the house to form a barrier belt to prevent rainwater seepage.

[0024] A drainage groove 12 is provided on the upper beam surface of the top side beam frame 11, and a sealing sleeve 13 flush with its cross section is provided at one end of the frame of the top side beam frame 11, and a sealing plug 14 protruding outward is provided at the other end of the frame of the top side beam frame 11. The drainage groove 12 is a U-shaped structure, and the sealing sleeve 13 and the sealing plug 14 are both made of natural rubber material, and the sealing sleeve 13 and the sealing plug 14 are interference fit with each other. When adjacent drainage groove structures are installed side by side in sequence, when adjacent drainage beams 1 are spliced ​​adjacent to each other in sequence, the interference fit buckles of adjacent sealing sleeves 13 and sealing plugs 14 are used to keep the joints of adjacent drainage beams 1 staggered and sealed, so as to prevent rainwater from leaking from the joints of adjacent drainage grooves 12 and improve its integrated sealing installation performance.

[0025] The waterproof pad 2 includes a sealing pad 21, and the back plate of the sealing pad 21 is arranged with multiple groups of deformation grooves 24. The waterproof pad 2 is made of one of silicone rubber materials or fluororubber materials. The multiple groups of deformation grooves 24 are arranged at equal intervals. By utilizing the waterproof pad 2 with elastic deformation, it can be installed on the wall of the house more tightly under external extrusion pressure. At the same time, by utilizing the extrusion deformation of the deformation grooves 24, the sealing performance between the wall and the wall can be further improved, thereby isolating rainwater from the wall and preventing rainwater from seeping into the room along the wall.

[0026] The top surface of the sealing pad 21 is provided with a diversion slope 22, and the plate surface of the diversion slope 22 is arranged in an array form with multiple groups of diversion inclined holes 23. The slope of the diversion slope 22 is not less than 45°, and the slope of the diversion inclined holes 23 is not less than 10°. By utilizing the inclined diversion of the diversion slope 22, the rainwater flowing down the wall is diverted to the drainage groove 12 of the drainage beam 1, and when rainwater seeps along the wall, the seeping rainwater can be diverted by utilizing the conduction between the diversion inclined holes 23 and the wall to prevent the rainwater from continuously seeping downward into the room.

[0027] The working principle of the utility model is as follows: when the drainage trough structure is installed and used, the combination of the drainage beam 1 and the waterproof pad 2 is installed at the roof position of the house based on the bolt tightening of the expansion bolt 3, and at the same time, the expansion bolt 3 is used to compress the waterproof pad 2 with elastic deformation, and the tight seal is squeezed on the wall of the house to form a barrier belt to prevent rainwater from seeping in. Then, the drainage trough structure is spliced ​​and installed in sequence in the same way. When adjacent drainage trough structures are installed side by side in sequence, when adjacent drainage beams 1 are spliced ​​and adjacent in sequence, the interference fit buckles of the adjacent sealing sleeves 13 and the sealing plugs 14 are used to keep the joints of the adjacent drainage beams 1 staggered and sealed, so as to prevent rainwater from leaking out of the joints of the adjacent drainage grooves 12, thereby ensuring the installation sealing of the drainage trough structure.

[0028] Later, during the use of the drainage trough structure, the inclined diversion surface 22 is utilized to divert rainwater flowing down the wall, and the rainwater is diverted to the drainage trough 12 of the drainage beam 1, and the rainwater is discharged in a direction. When rainwater seeps along the wall, the seeping rainwater can also be diverted by utilizing the connection between the diversion inclined hole 23 and the wall, so as to prevent the rainwater from continuously seeping downward into the room.

[0029] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
