Abstract

The utility model discloses a composite leakage-proof structure for roof, which comprises an upper top plate, a heat-insulating layer, roof purlines, a lower top plate, and screws, wherein, the upper top plate is composed of a plurality of corrugated plate sheets with large-capacity tanks; the mutually lapped peaks of the corrugated plate sheets are additionally provided with mounting frames which are fixed to the roofing purlines by double-tooth tapping screws. The utility model with the large capacity tanks effectively prevents the roof from leaking rainwater; the double-tooth tapping screws fastening the lap joint of the upper top plate is reliable, and the utility model has good tightness, and plays the anti-leakage effect; meanwhile, the utility model has the advantages of bright and simple whole structure, easy installation, and good anti-vibration, and the utility model can be widely used for leakage-proof structure of roof in construction, and can be used in insulation works.

Description

Composite roof is prevented water-leaking structure

The utility model relates to the anti-water-leaking structure of a kind of composite roof of building, particularly composite roof.

At present, owing to adopt the close purlin structure of light steel, it is big that the building roof of colored sandwiched plate has span, construction costs is low, short construction period, indoor spacious and well-lighted, attractive in appearance, advantage such as generous, therefore, this roof structure is widely used in industrial premises, physical culture field boundary shop and prosperous recently furniture store, in all kinds building roof engineerings such as building materials city and small item city field boundary, particularly show in the field boundary composite fireproof roofworks, but in the roofing installation, all need overlap between the per two adjacent steel plates usually, owing to color steel sheet produces the resilience that contour plate appears in internal stress in the die mould process, the shortcoming that causes the Bian Fengyou on steel plate both sides to subside, the intensity of invar plate and hardness and thickness is different again, and peak, the profiled sheet limit degree of subsiding is also inequality, and the crest height of steel plate limit peak lap-joint all is lower than the height of normal crest.In addition, peak, limit lap-joint must fix with the self tapping self-drilling screw, and the pressure that tapping screw punches on crest makes the height of lap-joint's crest also have reduction, shows that according to measured data it is highly only for about 55% of height should be arranged, referring to accompanying drawing 5.When running into heavy rain weather, the ponding height surpasses the height of roofing lap-joint in the water tank, can produce the roof leaking phenomenon, if 60 meters long roofings are provided with 81 limits peak lap-joint, so, causes the degree of indoor roof leaking hardly imaginable.

The purpose of this utility model provides a kind of thermal-insulating waterproof, makes simple, the anti-water-leaking structure of the easy composite roof of installation.

The purpose of this utility model is achieved in that

It comprises upper strata top board, insulation layer, roof purline, lower floor's top board and screw, its feature is: this upper strata top board is made up of some waveform plates with big water tank, this waveform plate crest place of overlap joint is mutually set up mounting bracket, on the aspect purlin, this screw is two tooth tapping screws by screw.

Because the upper strata top board water tank that technique scheme is taked is big, is fit to long roofing and uses wide application; Take the mutual overlapping part of waveform plate to increase the measure of mounting bracket, make the crest of the mutual lap-joint of waveform plate keep due height, guarantee that water tank has the degree of depth of answering, and effectively prevents the roof leakage rainwater; Choose two tooth tapping screws, because of the root of its turret head has the tooth button to attack in the crest of waveform plate, but one side pull-up waveform plate, guarantee that peak, limit lap-joint is fixing reliable, and good airproof performance, during on the other hand with foot-operated upper strata top board, the waveform plate can not slided on screw rod, thereby play the effect of leakproof.In addition, it is simple that the utility model also has making, advantage easy for installation.

Below in conjunction with drawings and Examples the utility model is described in further detail.

Referring to accompanying

drawing

1,2,3,4, the utility model comprises upper strata top board 1, insulation layer 2, roof purline 3, lower floor's top board 4 and screw 5, its at the middle and upper levels top board 1 form by some waveform plates with big water tank, this waveform plate crest place of overlap joint mutually is provided with mounting bracket 6, be fixed on the roof purline 3 by screw 5, screw 5 is two tooth tapping screws.By technique scheme, the prior galvanized steel plain sheet that 1.2mm is thick, its developed surface is 200mm * 40mm, it is standby to make mounting bracket 6.Earlier insulation layer 2 is layered on the side of roof purline 3, paves and spread even; Upper strata top board 1 is layered on above the insulation layer 2, is screwed, insulation layer 2 adopts super glass wools, has good fireproof heat insulating performance, and this plays fine glass wool thickness is 100mm, at roof purline 3 places by upper strata top board 1 boil down to 10mm.Roof purline 3 adopts C shaped steel, plays roof supporting, wind resistance and anti-snow load, and upper strata top board 1 is made up of some waveform plates with water tank, and this waveform plate adopts 5125 type profiled sheets, and it is reasonable to have stock utilization, the characteristics that the machine-shaping expense is low.The mutual lap-joint of waveform plate is corresponding to roof purline 3 places then, mounting bracket 6 is placed on the insulation layer 2 at roof purline 3 places, supports the crest of lap-joint, guarantee that crest herein has enough height, be fixed on the roof purline 3 with screw 5 at last, realize preventing the purpose of roof leakage.Screw 5 adopts two tooth tapping screws, when fixing upper strata top board 1, screw 5 is screwed to when needing the degree of depth, because the screw thread of these screw 5 turret head roots is attacked in the crest of upper strata top board 1, play the effect of tension waveform plate, when pin stepped on layer top board 1, crest place upper strata top board 1 can not slide on screw rod, fastening very reliable, play the leakproof effect.Lower floor's top board 4 usefulness screws 5 are fixedly mounted on the another side of aspect purlin 3, lower floor's top board 4 adopts Q901 type profiled sheet, make the indoor characteristics elegant in appearance that have, the utility model overall structure is simply bright, and have good characteristics of anti-seismic performance, can be widely used in the waterproof of building roof, in the heat insulating work.
