Description

The long gutter structure of terminal drop

Technical field

The utility model relates to a kind of roof drainage structures, and in particular to a kind of long gutter structure of terminal drop.

Background technique

Gutter refers to the recessed portion between two hip of building roofing.Sometimes When It Rains, rainwater focus in recessed portion again by Under rain pipe row, the ditch for gathering rainwater is thus referred to as gutter, is the important component of roof drainage system.Traditional gutter is multi-purpose The materials such as galvanized iron sheet, asbestos, reinforced concrete pregroove plate are made, and are developed in recent years by materials systems such as PVC, aluminium alloys Make.Gutter is also connected with the other component of drainage system, several rainwater holes are connected below gutter, and roof drain connects rain pipe, rain Water pipe reconnects discharge pipe and rainwater is discharged into irrigation canals and ditches or sewer.

Rainwater hole spacing in traditional Large-scale Roof drainage system is less than or equal to 24 meters, and it is horizontal to suspend many rainwater in midair below roofing Branch pipe installs small-bore dn outer diameter less than or equal to 90 millimeters of vinyon feed pipes, installer's filling-up hole work after punching on plate Make many and diverse bothersome, punch and be easily deformed leak, suspension and support works, and there are many metal component, and difficult in maintenance, cost of manufacture is high.

From the point of view of existing Large-scale Roof drainage gutter, there are drainage system complexity, pipeline it is more and disorderly, gutter punch it is more and The disadvantages of causing maintenance difficulties big.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies of existing open valley drainage system, provide a kind of displacement Greatly, install convenient is manufactured, management service is simple, cost is low, can be suitable for the day ditch water discharge system of heavy rainfall area roofing System, the roof structure especially suitable for large-sized workshop warehouse.

In order to achieve the above object, the technical solution adopted by the present invention is as follows：

A kind of terminal drops long gutter structure, gutter be set to building roofing across or edge, be fixed on mountain Above wall, expansion joint is set among gutter, adapts to the variation for causing gutter length because of temperature change, has in the middle part of gutter to two sides Gradient is conducive to rainwater and flows to two sides, and gutter outer end overhangs except roofing and gable, and the setting of overhanging portion is freely dropped Mouthful, roof drain is set at the mouth that drops, rain pipe is connected below drop mouth, rain pipe passes to the irrigation canals and ditches around building, entire roofing Gutter drainage system is wholy set in other than external wall.

The making material of the gutter can be cement concrete, PVC, aluminium alloy or galvanized iron sheet.

Overflow hole is arranged in the outer end of the gutter, and when roof drain or rainwater blockage, rainwater is discharged from overflow hole, it overflows The external relief sewer of discharge orifice, the water energy for going out overflow is concentrated into water column and flows down, or relief sewer can be accessed other and be lauched Guan Zhong, is arranged grid on the inside of overflow hole, and grid can be the diversified forms such as spherical mesh enclosure, cylindrical body mesh enclosure, grid can by sundries every From avoiding sundries by overflow hole plug.

The roof drain is spherical mesh enclosure shape, and the sundries that can effectively will go into gutter obstructs except mesh enclosure, no It enters in drop mouth.

Loudspeaker short tube is set between the roof drain and rain pipe, keeps the water flow for flowing into rain pipe more smooth.

The rain pipe is socket type pipeline, and installation is convenient, and dismounting and change is convenient.

The utility model has the advantages that：

1, there is no punch to be easily deformed the hidden of leak without any problem that punches on gutter, therefore also for the utility model Suffer from, gutter fabrication and installation technique is simple and direct, and gutter can reach 70 meters or more from origin-to-destination, and temperature change is provided among gutter Expansion joint will not generate the case where gutter deforms in the case where temperature range changes greatly.Gutter terminal overhangs to gable Outside, terminal sets drop mouth, and rain leader downspout is exposed on the outside of gable, is not take up interior construction spacing, rain leader downspout is held using major diameter Insert feed pipe, convenient disassembly.

2, overflow hole is arranged in the outer end of the gutter, and when roof drain or rainwater blockage, rainwater is discharged from overflow hole, prevents Only gutter trough plate inner product dilutional hyponatremia overflows, the external relief sewer of overflow hole from intermediate position, and the water energy for going out overflow is concentrated Flow down, or relief sewer can be accessed in other downcomers at water column, grid is set on the inside of overflow hole, grid can by sundries every From avoiding sundries by overflow hole plug.

3, loudspeaker short tube is set between roof drain and rain pipe, keeps the water flow for flowing into rain pipe more smooth.

4, roof drain is spherical mesh enclosure shape, can effectively will go into sundries in gutter and obstruct except mesh enclosure, not into Enter into drop mouth, and be conducive to cleaning personnel and clear up sundries, without removing mesh enclosure, the sundries around mesh enclosure surface need to only be gone It removes.
