With reference to Fig. 1, the continuous welding roofing layer structure that the embodiment of the present invention provides, comprises some independent and metal roofing boards 10 be fixedly connected with.Particularly, adjacent both sides of the edge between adjacent two roof panel 10 are respectively equipped with the first linking arm 11, second linking arm 12, some fixtures 20 are provided with between first linking arm 11 and the second linking arm 12, first linking arm 11, second linking arm 12 is connected with fixture 20 and is fixed by fixture 20, simultaneously, by in Fig. 1 shown in dotted line, the adjacent side length direction along adjacent two roof panel 10 is welded with the weld seam 30 for sealing the first linking arm 11 and the second linking arm 12.
In the present embodiment, first linking arm 11, by being connected between second linking arm 12 and fixture 20, weld seam 30 is formed by continuous welding again between the first linking arm 11 and the second linking arm 12, like this, not only strengthen the connection reliability between the first linking arm 11 and the second linking arm 12, improve wind resistance and take off ability, and, weld seam 30 good sealing effect, especially at the formation acclive roofing layer of tool or when there is long-span roofing layer, when avoiding roof ponding, to flow into roofing layer by the gap between the first linking arm 11 and the second linking arm 12 inner for water, good water-proof effect.
Particularly, by Fig. 2, Fig. 3, can find out, fixture 20 comprises level first stator 21 and is located at vertical second stator 22 on level first stator 21.Vertical second stator 22 is for being engaged with the first linking arm 11, second linking arm 12, and level first stator 21 is for fixing the structure after above-mentioned occlusion.The end of vertical second stator 22 bends out the first resettlement section, resettlement section 221, first 221 downwards and be arranged in parallel with vertical second stator 22 and form the first receiving space 40 betwixt.
First linking arm 11 end is bent to form the first buckle portion 111 downwards, the end of the first buckle portion 111 is upwards bent to form the second buckle portion 112, the upper end of the first linking arm 11 and the first buckle portion 111 wrap on vertical second stator 22 and the first resettlement section 221 thereof, and the second buckle portion 112 is contained in the first receiving space 40.
The second receiving space 50 is formed between second buckle portion 112 of the first linking arm 11 and the first resettlement section 221, second linking arm 12 end downward bent the 3rd buckle portion 121, the upper end of the second linking arm 12 is contained in the second receiving space 50 through the second buckle portion the 112, three buckle portion 121.
As shown in Figure 3, in the present embodiment, weld seam 30 is a place, and weld seam 30 is located between the first linking arm 11 and the second linking arm 12.And weld seam 30 is formed along the first linking arm 11 and the second linking arm 12 length direction continuous welding.
As an alternative, also weld seam 30 can be arranged on position as shown in Figure 4, Figure 5, be located between the second linking arm 12 and the second buckle portion 112 by weld seam 30.Be arranged on this, equally, play effect that is firm and waterproof.
As an alternative, also can by weld seam 30 in position shown in Fig. 6, Fig. 7.Namely weld seam 30 is two, and wherein a weld seam 30 is located between the first linking arm 11 and the second linking arm 12, and another weld seam 30 is located between the second linking arm 12 and the second buckle portion 112.Like this, firm and waterproof effect strengthens further.
In the present embodiment, the first linking arm 11, second linking arm 12 is welded and after being engaged with vertical second stator 22, is fixed by level first stator 21.Level first stator 21 is fixed by screw, is fixed by fixture 20 like this, thus is fixed by adjacent two roof panel 10.
Fig. 8 be fixture 20 and two roof panel 10 unassembled time side schematic view; And Fig. 2 is the schematic diagram after assembling.When mounted, only to need manually or machine is bent, therefore, site operation is flexible for installation, quick, and moulding is convenient, need not use silica gel, avoids pollution and problem of aging, increases the service life.
Metal roofing board 10 is applicable to all metal material panels, preferred titanium zine plate, copper coin or aluminium sheet.The width of roof panel 10 and thickness can be chosen according to the needs of practical application.And the stile height of the first linking arm 11, second linking arm 12 is preferably between 25mm-38mm, certainly, also can heighten according to actual needs or turn down.
Ability is taken off, according to the tension pull out force between nail tool size and roof panel 10 structure, in the quantity of roof panel 10 scope domestic demand determination fixture 20 for strengthening wind resistance.
Roofing layer is damaged for preventing expanding with heat and contract with cold of roof panel 10.In the present embodiment, be divided into fixed fixture in the middle part of fixture 20, part is slidingtype fixture.As shown in Figure 9, in fixed fixture, vertical second stator 22 is fixedly connected on level first stator 21.In slidingtype fixture as shown in Figure 10, vertical second stator 22 is slidably connected on level first stator 21.Particularly, one lateral edges of level first stator 21 upwards extends to form kink 211, kink 211 is provided with fluting 212, and the lower limb of vertical second stator 22 is provided with hook-shaped afterbody 222, and afterbody 222 hook to be located in fluting 212 and can be moved along fluting 212.Like this, when roof panel 10 expands with heat and contract with cold, vertical second stator 22 drives the first linking arm 11, second linking arm 12 overall relative level first stator 21 to move, thus prevents roofing layer to be destroyed because expanding with heat and contract with cold.
Present invention also offers a kind of Roof system (not shown).Roof system comprises above-mentioned continuous welding roofing layer structure, and is positioned at the ventilation noise reduction layer below continuous welding roofing layer structure, moistureproof anti-spoke layer, leveling layer, supporting layer, insulation layer, dust layer and furred ceiling backplane level from top to bottom successively.Wherein, windproof noise reduction layer is three-dimensional ventilation noise reduction silk screen, namely has the effect of air lock external noise, can also play logical wind action simultaneously.Moistureproof anti-spoke layer is positioned at below ventilation noise reduction layer, has moisture proof and radiation-resistant function.Leveling layer, guarantee the planarization of roofing layer entirety, and supporting layer is played a supporting role, insulation layer provides heat insulation function, and dust layer can prevent indoor by contamination by dust, and furred ceiling backplane level plays furred ceiling effect.By above each layer, reach good sound insulation and noise reduction effect.
These are only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
