Abstract
The invention mainly discloses a roofing eave waterproof structure. In the roofing eave waterproof structure, an eave supporting closing edge is arranged at the junction of a roof panel and a wall plate; roofing heat-preserving cotton is paved on the roof surface to press part of the eave supporting closing edge; and the roof panel is covered on the roofing heat-preserving cotton and is fixedly connected through a roofing fastener. The roofing eave waterproof structure is designed from the angle of preventing wind, water and snow and all the accessories are coordinated, so that the requirements of rigidity and wind suction resistance are met and rainwater penetration can be avoided simultaneously.
Description
Technical field
The present invention relates to belong to building unit node field, special relevant with a kind of roofing eave waterproof structure.
Background technology
Industrial construction and most of public building of application, nearly all adopt metal roofing board, and the cornice of metal roofing board is the emphasis area of roof waterproof now.Often cause and leak, cause indoor ponding, destroy building and use function.The cornice place, due to the convergent point that is rainwater and accumulated snow, easily causes the cornice place because rigidity is inadequate, and makes to damage simultaneously.
In order to address the above problem, the inventor designs a kind of roofing eave waterproof structure, and this case produces thus.
Summary of the invention
The purpose of this invention is to provide a kind of roofing eave waterproof structure, from the angle design of wind and water preventing snow defence, each accessory, by co-ordination, meets rigidity fully, resists the wind suction requirement, also can avoid rainwater to infiltrate simultaneously.
In order to achieve the above object, the present invention is achieved through the following technical solutions:
A kind of roofing eave waterproof structure, be included in roof panel and wallboard intersection and be provided with cornice support receipts limit, and the roof heat insulation cotton is laid on roofing pushes down part cornice support receipts limit, and roof panel covers on the roof heat insulation cotton, by the roofing securing member, is fixedly connected with.
Described cornice supports the receipts limit and is fixed on the roofing eave purlin.
Described cornice supports and receives limit is that steel plate bending forms, and comprises interior supporting plate, external connecting plate, between the two by a chamfered transition, forms external connecting plate higher than interior supporting plate.
Described cornice supports the outside link plate of receiving in limit and bends downwards at outer edge, forms crisperding.
Described roof heat insulation cotton pad is placed on interior supporting plate, with outside link plate, flushes.
On described external connecting plate, by the adhesive seal adhesive tape, with roof panel, be connected.
Described roofing securing member is positioned on sealant tape.
Fill plug in metal in described roof panel crest space.
After adopting such scheme, the present invention has many beneficial effects:
From the angle design of wind and water preventing snow defence, meet the requirement of each side in the present invention.Rainwater is collected to cornice from ridge, though weight ratio is larger, owing to there being cornice to support the support of receiving limit, can meet the requirement of rigidity fully; Because eaves board cornices, under the wind suction active state, easily dig simultaneously, because the fixing of supporting roofing securing member arranged, can resist the effect of wind suction.In metal, plug has solved the cavity existence overlapped between roof panel, by it, with the sealant tape acting in conjunction, has both been solved wind and has directly recharged in building, also can avoid rainwater to infiltrate simultaneously.
The accompanying drawing explanation
The installation steps one that Fig. 1 is preferred embodiment of the present invention;
The installation steps two that Fig. 2 is preferred embodiment of the present invention;
The installation steps three that Fig. 3 is preferred embodiment of the present invention;
The installation steps four that Fig. 4 is preferred embodiment of the present invention;
Fig. 5 is that in Fig. 1, cornice supports receipts limit enlarged drawing.
The specific embodiment
By reference to the accompanying drawings, preferred embodiment of the present invention is described in further details.
A kind of roofing eave waterproof structure, the parts that are mainly concerned with comprise: roof panel 1, roofing eave purlin 2, cornice support receives plug 7 in limit 3, roof heat insulation cotton 4, sealant tape 5, roofing securing member 6, metal.
The present invention forms a good syndeton, windproof and rain proof for shingle nail and roof panel junction.
At first at its intersection, cornice is set and supports receipts limit 3, cornice supports receipts limit 3 and is formed by the pressurising of metal steel, comprises interior supporting plate 31, outside link plate 32.Interior supporting plate 31 is fixed on the already present roofing eave purlin 2 of room body itself, between outside link plate 32 and interior supporting plate 31, by inclined-plane 33 transition, makes the height of outside link plate 32 higher than interior supporting plate 31.And the downward infolding of the outer edge of outside link plate 32 forms a crisperding, for dash.
Roof heat insulation cotton 4 is laid on roofing, just pushes down interior supporting plate 31, can fill up the difference in height between interior supporting plate 31 and outside link plate 32.
First stick a sealant tape 5 on outside link plate 32, sealant tape 5 is two-sided has viscosity.Owing to existing small gap between metal fittings, under the effect of capillary effect, can make rainwater infiltrate in node fully, accumulation through certain hour, just may cause the indoor phenomenon of leaking that occurs, and this type of drainage can not be found out the situation of actual breakthrough substantially, it is " once doing Lou that the metal Roof why Here it is often occurs leaks, repair and more leak " main cause, so waterproof of the present embodiment sealant tape 5 used own, adhesive strength is high, tensile strength is high, for interface deformation and cracking strong adaptability, there is excellent chemical resistance, weatherability and corrosion resistance.The use of sealant tape 5, made up the defect connected between metalwork, can fully, closely fill the possible space between each accessory, reaches the obstruct capillary effect, the possibility that thoroughly stops rainwater to infiltrate.
Roof panel 1 covers on roof heat insulation cotton 4, between outside link plate 32 and roof panel 1, by sealant tape 5, pastes, then along the track of sealant tape 5 fixing roofing securing member 6 again.Owing to needing certain rigidity to connect between accessory, it is tightr that roofing securing member 6 makes to connect between several metal fittings, can prevent from destroying whole node under various load actions.Simultaneously in order to prevent the capillarity produced due to micro-pore between securing member, thereby causing the infiltration roofing securing member of rainwater to be equipped with the EPDM(ethylene propylene diene rubber) sealing ring solves problems.The securing member body adds that the EPDM sealing ring is used in conjunction with, and makes properties of product have effective Corrosion Protection, reduces and safeguards and repair cost, saves total cost.
In addition, due to the connection between roof panel, form the interior void of roof panel 1 lap joint, rainwater is under the state of wind, and the water in gutter, or wind, can directly enter fully or infiltrate this cavity, causes the drainage in building.So cause and leak in order to eliminate this cavity, adopt plug 7 in metal to cram, avoid the infiltration of rainwater and wind.
The present invention when mounted, at first supports and receives limit 3 at cornice, if there is shingle nail first to lay shingle nail.Laying sealant tape 5 in cornice support receipts 3 tops, limit is that in installation roof panel and metal, plug 7 is ready.Spread the roof heat insulation cotton, install plug 7 in metal, and fastening with the roofing securing member.Then up lay again roof panel, be fixed on cornice with roofing securing member 6 and support on receipts limit 3, install.
Above-described embodiment is only for the inventive concept of the present invention of explaining, but not to the restriction of rights protection of the present invention, allly utilizes this design to carry out the change of unsubstantiality to the present invention, all should fall into protection scope of the present invention.
