Description

Technical Field

[0001] The present application relates to the field of building technology, and in particular to a waterproof inner gutter. Background Art

[0002] Gutter refers to the concave part between the two spans of the roof of a building. Roof drainage is divided into organized drainage and unorganized drainage (free drainage). Organized drainage generally collects rainwater into the gutter and then discharges it through the rainwater pipe. The ditch that collects rainwater is called a gutter. Gutters are divided into inner gutters and outer gutters. The inner gutter refers to the gutter inside the outer wall, which usually has a parapet; the outer gutter is the gutter that protrudes from the outer wall, which usually has no parapet.

[0003] Gutters are mostly made of tinplate or asbestos cement. During the long-term construction and installation process of gutters, since the iron sheets of the gutters are installed in whole sections to conduct water, if there is a leak in the iron gutter, it will be very difficult to repair the entire section. The leak will also cause deep corrosion of the steel parts, which will not only seriously affect the user's satisfaction with the overall construction quality, but also seriously affect the user's service life and safety. Therefore, a waterproof inner gutter is proposed to solve the above problems. Utility Model Content

[0007] The installation groove is arranged on the inner side of the wall and located on the outer side of the gutter iron sheet.

[0008] By adopting the above technical solution, since the entire gutter structure is divided into a number of iron hooks and iron sheets, and connecting strips are fixed on one side and the other side (i.e., the head and the tail) of the gutter iron sheet, it is convenient for construction workers to connect the head and the tail of the gutter iron sheet, and then fix them on the wall with mounting screws. During inspection and maintenance, it is only necessary to disassemble the gutter iron sheet at the leaking end to achieve maintenance of the leaking section, thereby improving the convenience of maintenance.

[0009] Furthermore, the gutter iron sheet and the connecting strip are both in the shape of a "+"; the number of the iron hook iron sheets is several, and the several gutter iron sheets are equidistantly distributed front to back and head to tail.

[0010] By adopting the above technical solution, the gutter iron sheets and connecting strips connected end to end form the entire gutter drainage structure.

[0011] Furthermore, the number of the connecting strips is several, and the connecting strips are symmetrically distributed on one side and the other side of the gutter iron sheet, and the specification of the connecting strips on one side is greater than that of the connecting strips on the other side.

[0012] By adopting the above technical solution, the connecting strip on one side can be sleeved on the outside of the connecting strip on the other side and connected and fixed by installing screws.

[0013] Furthermore, a mounting hole located outside the mounting screw is provided on the connecting strip, and the mounting groove is triangular in shape.

[0014] By adopting the above technical solution, a plurality of gutter iron sheets connected end to end can be connected and fixed end to end through mounting strips and mounting screws.

[0015] Furthermore, the inner waterproof layer is an acrylic waterproof coating, and the outer waterproof layer is a polymer cement-based waterproof coating.

[0016] By adopting the above technical solution, the inside and outside of the gutter iron sheet have good aging resistance, elongation, elasticity, adhesion and film-forming properties; and the waterproof layer is a closed system with good overall waterproof effect, which is particularly suitable for the construction of special-shaped structures.

[0017] Furthermore, the thermal insulation layer is a hard polyurethane layer, and the connecting waterproof layer is a new HDPE waterproof layer.

[0018] By adopting the above technical solution, the waterproofness of the connection between the gutter iron sheet and the wall can be improved because the HDPE waterproof material has good tensile properties, good waterproof properties, good anti-trampling, good anti-silt pollution effects, strong UV resistance, strong water immersion resistance, high peeling strength, and complete bonding with the structure, eliminating the possibility of water leakage.

[0019] Furthermore, the wall and the gutter iron sheet are both inclined at one side away from the installation groove, and threaded holes for fixing with installation screws are provided at the inclined part of the wall and in the installation groove.

[0020] By adopting the above technical solution, a plurality of gutter iron sheets connected end to end can be fixed in the installation groove and the inclined part of the wall by means of installation screws.

The waterproof inner gutter divides the entire gutter structure into several iron hooks and iron sheets, and a connecting strip is fixed on one side and the other side (i.e., the head and the tail) of the gutter iron sheet, so that it is convenient for construction workers to connect the head and the tail of the gutter iron sheet, and then fix it on the wall with mounting screws. During inspection and maintenance, it is only necessary to disassemble the gutter iron sheet at the leaking end to achieve maintenance of the leaking section, thereby improving the convenience of maintenance.

[0023] 2. The waterproof inner gutter has an inner waterproof layer coated on the inner side of the gutter iron sheet, and the inner waterproof layer is an acrylic waterproof coating, which can improve the waterproof effect of the inner side of the gutter iron sheet. Since a sealing ring is fixed on the inner side of the connecting strip, the sealing of the gutter iron sheet after being connected by the connecting strip can be increased. Moreover, since the outer side of the iron hook iron sheet is coated with an outer waterproof layer, in cooperation with the connecting waterproof layer, the waterproof effect of the inner side, the connection and the outer side of the entire gutter structure can be increased.
