A kind of anti-clogging eaves gutter and eaves gutter cover plate thereof
Technical field
The utility model belongs to the building materials field, and definite saying so relates to steel work and go along with sb. to guard him a kind of anti-clogging eaves gutter and the eaves gutter cover plate of using in the system roof drainage system thereof.
Background technology
At present, the eaves gutter that existing steel work is gone along with sb. to guard him in the system mainly is made of opening water receiving tank up, there is not overcover on the opening of water receiving tank during installation, thereby foreign matters such as the branch that descends slowly and lightly after using over a long time, leaf are deposited on the outfall of stopping up eaves gutter in the eaves gutter easily, the drainage efficiency of eaves gutter drainage system is reduced, and the accumulation of the foreign matter that stops up also influence the attractive in appearance of eaves gutter.
The utility model content
The purpose of this utility model is at above-mentioned defective, and a kind of eaves gutter that can prevent that outfall is blocked is provided; Another purpose of the present utility model provides a kind of cover plate that can hide eaves gutter.
For achieving the above object, the technical solution of the utility model is: a kind of eaves gutter, comprise the water receiving tank that water supply stream passes through, on the opening of described water receiving tank, be covered with a cover plate, cover plate comprises the leakage board that extends along the water receiving tank length direction, the both sides extension of leakage board is provided with the junction plate that cooperates with the both sides side plate overlap joint of water receiving tank, and gathering on the described leakage board offers leaking hole, and a side opening of leaking hole is along the flanging that is provided with downward bending.
The interior plate that is used for cooperating with the eaves overlap joint on the described water receiving tank is higher than the outer panel of its opposite side, and described leakage board is along the incline direction setting between inside and outside side plate, and described leaking hole is provided with the side opening edge of flanging towards the interior plate direction.
Described flanging and leakage board are structure as a whole, and the shape of flanging is identical with the leaking hole shape.
Its length direction of described leakage board upper edge offers at least two row's leaking holes, and each row's leaking hole is provided with at interval, and adjacent two rows' leaking hole is interspersed.
A kind of eaves gutter cover plate comprises along its length the leakage board that extends, and the both sides of leakage board are extended respectively to be provided with and are used for the junction plate that cooperates with eaves gutter water receiving tank overlap joint, and gathering on the leakage board offers leaking hole, and the side opening edge of leaking hole is provided with the flanging of downward bending.
Described flanging and leakage board are structure as a whole, and the shape of flanging is identical with the leaking hole shape.
Its length direction of described leakage board upper edge offers at least two row's leaking holes, and each row's leaking hole is provided with at interval, and adjacent two rows' leaking hole is interspersed.
The utility model adopts technique scheme, it is provided with a cover plate that can hide the eaves gutter opening on the water receiving tank of eaves gutter, offer leaking hole on the cover plate, leaking hole is provided with downward flanging, can stop that foreign matters such as branch, leaf fall into the water receiving tank that water supply stream passes through, and prevent that the outfall of eaves gutter from being stopped up by foreign matter, simultaneously, rainwater can flow in the water receiving tank by leaking hole, and can not reduce the drain function of eaves gutter; Of the present utility model simple in structure, easy for installation, and both artistic and practical.

The specific embodiment
Embodiment one: as Fig. 1, shown in Figure 3, between the bottom, edge of roof panel 103 and roof purlin 104, be fixed with the eaves gutter that is used for draining, eaves gutter comprise opening up, the water receiving tank 102 that passes through of water supply stream, the bottom of water receiving tank 102 is provided with outfall, is connected with sewer pipe 105 on the outfall.For the benefit of rainwater flows, the inside wall that is used on the water receiving tank 102 cooperating with the roofing overlap joint is higher than its corresponding lateral wall, in the opening upper edge of water receiving tank 102, lateral wall tilts to be covered with an eaves gutter cover plate 101, this eaves gutter cover plate 101 comprises the leakage board 1 that extends and fasten with water receiving tank 102 openings along its length direction, the both sides of leakage board 1 extend respectively be provided with water receiving tank 102 in, the junction plate 2 that the external groove sidevall overlap joint cooperates, 3, on leakage board, be densely covered with leaking hole 4, for guaranteeing that rainwater can flow in the water receiving tank 102 fully, each leaking hole 4 in picturesque disorder alternately arrangement.In the present embodiment, each leaking hole 4 is an isosceles triangular structure, the base of this triangle leaking hole 4 is towards the inside wall direction of water receiving tank 102, be respectively arranged with the flanging 5 of downward bending on the base of each leaking hole 4, for ease of processing and manufacturing, simplify procedure, flanging 5 is the triangular flaps 5 with the identical integrative-structure of leaking hole 4 shapes.Is triangular flaps 5 30 with the angle of leakage board 1? to 60?, make it in permeable, can stop foreign material such as branch, leaf and enter and stop up outfall in the water receiving tank, simultaneously, this flanging 5 can also be adjusted the size of leaking hole to adapt to different regions.
During installation, it is on the inside wall and by screw roof panel 105, eaves gutter cover plate 101 and water receiving tank 102 to be fixed on the roof purlin 104 together that the junction plate on the eaves gutter cover plate 101 2 is overlapped on water receiving tank 102; The junction plate 3 that cooperates at eaves gutter cover plate 101 and water receiving tank 102 lateral walls overlap joint and the lateral wall of water receiving tank 102 are connected by screw, to prevent strong wind eaves gutter cover plate 101 are scraped.
Embodiment two: present embodiment two is that with the difference of embodiment one leaking hole of offering on the eaves gutter cover plate 101 4 ' is rectangle structure, and the tabs 5 ' that is wholely set on the corresponding leaking hole 4 ' also is a rectangle structure.
The utility model is not limited to the foregoing description; leaking hole on the eaves gutter cover plate can also be semicircle, half elliptic, other shape such as trapezoidal; no matter but how its structure or shape change; as long as the eaves gutter cover plate is provided with leaking hole and the leaking hole edge is provided with the integrative-structure flanging of bending downwards, all within protection domain of the present utility model.
