Awning cornice structural system
Technical field
The utility model belongs to construction steel structure awning field, is specifically related to a kind of awning cornice structural system.
Background technology
At present, in the construction steel structure engineering, the awning common practices all is to adopt two-layer color steel up and down, middle make outrigger with shaped steel, the gradient is for turning forward, i.e. draining forward, and awning also recedes greatly certainly, adopt built-in gutter, be formed with and organize draining, the rainwater pipe can descend along wall.But with regard to the awning of rainwater to the front row, the overwhelming majority is direct free draining now, and outward appearance is neither attractive in appearance, and during raining, also can splash by rainwater in the awning position; Some awning, take to carry additionally a color steel gutter in awning cornice end, because awning is encorbelmented away apart from metope one segment distance, the rainwater pipe is difficult for fixing, the just direct color steel gutter two ends that have are not sealed, directly rainwater is arranged towards the awning both sides, because the direct plug-in cornice of color steel gutter, hanging point is under top plate, do not produce below and get in touch,, be the wind suction that makes progress from building wind load stressing conditions with the awning structure, rather than wind pressure down, so cornice end color steel gutter turns over unstability on easily under wind action, thereby loses the effect of cornice color steel gutter, and the two ends rainwater is concentrated discharging, and the ground of permanent position is washed away seriously.
The utility model content
In order to overcome the above deficiency of existing awning cornice structural system, the purpose of this utility model is: a kind of awning cornice structural system is provided, this awning cornice structural system is simple in structure, with low cost, easy construction, be convenient to dismounting, the structural strength height can not produce that rainwater splashes or lumped scour ground.
The technical scheme that its technical problem that solves the utility model adopts is as follows:
A kind of awning cornice structural system, it comprises awning upper plate, awning outrigger, awning lower plate and awning purlin, awning upper plate and awning lower plate are contained in the above and below of awning outrigger respectively, and the awning purlin is contained in the end face of awning outrigger, and are fastenedly connected with awning upper plate and awning lower plate.Described awning cornice structural system also comprises cornice baffle plate, metal drawknot folding part and end shrouding, described end shrouding is installed on the lateral surface of awning purlin, described metal drawknot folding part is a flat bending part, the vertical folding section of this metal drawknot folding part is contained in the lateral surface of end shrouding, by securing member awning purlin, end shrouding and metal drawknot folding part three is fastenedly connected; Described cornice shutter is in the outer end of awning cornice structural system, and fixedlys connected respectively with the cornice overhanging end of awning upper plate and the level folding section of metal drawknot folding part.
Described cornice baffle plate is bent into continuous four sections by the monoblock color steel: upper plate plate overhead gage, front baffle plate, lower baffle plate and draining board; Upper plate plate overhead gage and lower baffle plate are horizontal baffle, and the front baffle plate is a vertical baffle.Upper plate plate overhead gage covers the cornice overhanging end at the awning upper plate, rivets with upper plate plate overhead gage; Lower baffle plate is close to the soffit of metal drawknot folding part level folding section, rivets with lower baffle plate.
Compared with prior art, the beneficial effects of the utility model are:
1, simple in structure, easy construction
The main member of the utility model awning structural system is combined by being spirally connected or riveting by band steel, color steel bending and molding, and it is simple in structure, is convenient to construction.
2, structural strength height can not produce that rainwater splashes or lumped scour
Owing to used metal drawknot folding part in the utility model awning structural system, this metal drawknot folding part intensity height, make the awning cornice extention material can be because of unstability under the wind suction effect, owing to the cornice baffle plate has blocked rainwater under the suitable slope, make it can not produce to splash, can not form rainwater lumped scour ground.
