Abstract

The utility model provides a double-slope ridge node structure for a profiled metal plate roof, which comprises a purlin, a roof panel, a ridge cover, a foam plug and a water retaining plate; The purlin extends downwards obliquely, and the roof panel is fixedly connected to the top surface of the purlin by self-tapping screws; the roof panel is a profiled metal corrugated plate structure. And the ends between the roof panels on both sides are fixedly connected with a roof ridge cover plate by rivets; the roof ridge cover plate is covered on the gap between the roof panels on both sides, and the top of the roof ridge cover plate is inclined from the center to the two sides respectively. It extends downward, and the two sides of the roof ridge cover are folded to form a Z-shape and are attached to the roof panel and extend; The roof ridge cover plates on both sides of the plug are also fixed and connected by rivets with full-length angle steel as a water retaining plate.

Description

Profiled metal sheet roof double-slope ridge node structure

Technical Field

The utility model relates to the field of buildings, in particular to a profiled metal sheet roof double-slope ridge node structure.

Background

The metal roof is a roof form which adopts a metal plate as a roof material and combines a structural layer and a waterproof layer into a whole. The thickness is generally 0.4 to 1.5mm, and the surface of the plate is generally coated. Due to the difference of materials and coating quality, the service life of some plates can reach more than 50 years. The preparation shape of board has a variety, and some be the composite sheet, be about to the heat preservation complex between two-layer sheet metal, also some be the veneer, during the construction, some board is assembled at the good back scene of mill processing, and some needs according to roofing engineering are processed at the scene. The heat-insulating layer is well compounded in a factory and can also be manufactured on site. Therefore, the metal plate roofing has various forms and is used from large public buildings to factory buildings, storehouses, houses and the like. And the seepage often can appear in the two sloping ridge node position of die mould sheet metal roofing, in case appear can lead to metal roofing corrosion damage, influence the use.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a profiled metal sheet roof double-slope ridge node structure aiming at the defects and shortcomings of the prior art, multiple anti-leakage measures are formed by a foam plug and a water baffle at the joint of a ridge cover plate and a roof plate, the structure is light and convenient, the load on a keel is small, and the waterproof effect is good.

In order to achieve the purpose, the utility model adopts the technical scheme that: a profiled metal sheet roofing double-slope ridge node structure comprises purlins, roof boards, ridge cover plates, foam plugs and water baffles; the purlines are of longitudinal channel steel keel structures, the top surfaces of the purlines extend downwards from the roof ridge to the two sides of the roof in an inclined mode respectively, and the top surfaces of the purlines are fixedly connected with a roof panel through self-tapping screws; the roof panels are of a pressed metal corrugated plate structure, extend from the ridge to roof surfaces on two sides along the top surfaces of the purlines and incline downwards, and the end parts between the roof panels on the two sides are fixedly connected with ridge cover plates through rivets; the ridge cover plate is covered on the gap between the roof plates at the two sides, the top of the ridge cover plate is respectively inclined and extends downwards from the center to the two sides, and the two sides of the ridge cover plate are folded and attached to the roof plates in a Z shape to extend; the gap between the bottoms of the two sides of the ridge cover plate and the bottom surface of the inner cavity of the wave trough of the roof plate is filled with foam plugs, and the ridge cover plates on the two sides of the foam plugs are fixedly connected with through-length angle steel serving as water baffles through rivets.

Preferably, the extending distance from the center to the roof panels on two sides of the ridge cover plate is not less than 250mm, and the overlapping distance of every two ridge cover plates is not less than 150 mm.

Preferably, a through-length sealing adhesive tape is further laid between the fixed connection contact surfaces of the ridge cover plate and the roof plate.

The utility model has the beneficial effects that: this structure forms multiple antiseep measure through the foam end cap and the breakwater of ridge apron and roof boarding junction, and the light load of structure is little to the fossil fragments, and water-proof effects is good.

Drawings

The accompanying drawings, which are included to provide a further understanding of the utility model and are incorporated in and constitute a part of this application, illustrate embodiment(s) of the utility model and together with the description serve to explain the principles of the utility model.

Fig. 1 is a schematic view of a pressed metal plate roof double-slope ridge node structure, and fig. 2 is a schematic view of a section at a position A.

Wherein: 1 is the purlin, 2 is the roof boarding, 3 is the ridge apron, 4 is the foam end cap, and 5 is the breakwater.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in the figure, the profiled metal sheet roof double-slope ridge node structure comprises a purline 1, a roof panel 2, a ridge cover plate 3, a foam plug 4 and a water baffle 5; the purline 1 is of a longitudinal channel steel keel structure, the top surface of the purline 1 extends obliquely and downwards from the roof ridge to the two sides of the roof respectively, and the top surface of the purline 1 is fixedly connected with a roof panel 2 through self-tapping screws; the roof panels 2 are of a pressed metal corrugated plate structure, the roof panels 2 extend from the ridge to roof surfaces on two sides along the top surfaces of the purlines 1 and incline downwards, and the end parts between the roof panels 2 on two sides are fixedly connected with a ridge cover plate 3 through rivets; the ridge cover plate 3 is covered on the gap between the roof plates 2 at the two sides, the top of the ridge cover plate 3 is respectively inclined and extends downwards from the center to the two sides, and the two sides of the ridge cover plate 3 are folded and attached to the roof plates 2 in a Z shape to extend; the gap between the bottoms of the two sides of the ridge cover plate 3 and the bottom surface of the inner cavity of the wave trough of the roof plate 2 is filled with a foam plug 4, and the ridge cover plate 3 on the two sides of the foam plug 4 is fixedly connected with a full-length angle steel serving as a water baffle 5 through a rivet.
