In the use process of the metal and photovoltaic roof, some of the traditional insulation waterproof methods are constructed on the lower part of the insulation layer, and some are constructed on the upper part of the insulation layer. The insulation waterproof effect of the two is poor, and when the roof top is connected with a metal support, the node between the insulation layer / waterproof layer and the metal support is prone to leakage, thereby affecting the insulation waterproof effect. SUMMARY

[0004] To achieve the above purpose, the technical scheme adopted by the present application is a full-closed roof insulation waterproof method, a metal support is connected to the top of the concrete base layer, and the insulation waterproof method comprises the following steps:

[0005] Step 1: brushing a base treatment agent on the top of the concrete base layer and the outer periphery of the metal support;

[0006] Step 2: constructing a first waterproof layer on the top of the concrete base layer and the outer periphery of the metal support, so that the first waterproof layer covers the base treatment agent;

[0007] Step 3: constructing an insulation layer on the top of the first waterproof layer on the concrete base layer, so that the insulation layer is attached to the first waterproof layer on the lower part of the metal support;

[0008] Step 4: constructing a second waterproof layer on the top of the insulation layer and the outer periphery of the first waterproof layer on the upper part of the metal support;

[0009] Step 5: constructing a protection layer on the top of the second waterproof layer.

[0010] The full-closed roof insulation waterproof method further improves that the first waterproof layer comprises non-solidified rubber asphalt waterproof coating and self-adhesive polymer modified asphalt waterproof roll material, and when the above step 2 is performed, the non-solidified rubber asphalt waterproof coating is heated to 150-200 degrees Celsius and uniformly brushed on the top of the base treatment agent, and then the self-adhesive polymer modified asphalt waterproof roll material is laid on the non-solidified rubber asphalt waterproof coating.

[0011] A further improvement of the fully enclosed roof insulation and waterproofing method of the present invention is that, before performing step 3 above and after performing step 2 above, a modified bitumen adhesive is applied to the top of the first waterproof layer, and during the performance of step 3 above, the insulation layer is bonded to the first waterproof layer.

[0012] A further improvement of the fully enclosed roof insulation and waterproofing method of the present invention is that the insulation layer includes multiple foam glass insulation boards. When performing step 3 above, the multiple foam glass insulation boards are spliced ​​together in a staggered manner, and the modified asphalt adhesive is fully applied to each splice joint.

[0013] A further improvement of the fully enclosed roof insulation and waterproofing method of the present invention is that the second waterproof layer includes an asphalt-based surface and an SBS modified bitumen waterproof membrane. When performing step 4 above, the asphalt-based surface is connected to the top of the insulation layer and the upper part of the metal support, and the SBS modified bitumen waterproof membrane is pasted on the top of the asphalt-based surface using a hot-melt method.

[0014] A further improvement of the fully enclosed roof insulation and waterproofing method of the present invention is that the second waterproof layer further includes a two-component epoxy resin primer applied to the top of the SBS modified bitumen waterproof membrane and a polyurea waterproof coating sprayed on the top of the two-component epoxy resin primer.

[0015] A further improvement of the fully enclosed roof insulation and waterproofing method of the present invention is that, when spraying the polyurea waterproof coating, multiple sprayings are used, such that the spraying direction of the next spray is perpendicular to the spraying direction of the previous spray, and the spraying range of the next spray covers at least 50% of the spraying range of the previous spray.

[0016] A further improvement of the fully enclosed roof insulation and waterproofing method of the present invention is that the protective layer includes a weather-resistant polyurethane coating. When performing step 5 above, the weather-resistant polyurethane coating is rolled onto the top of the second waterproof layer, and the thickness of the roll coating is not less than 0.1 mm.

[0017] Compared with the prior art, the advantages of the present invention are:

Detailed Implementation

[0023] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0024] The fully enclosed roof insulation and waterproofing method of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Please see Figs. 1-2 As shown, a fully enclosed roof insulation and waterproofing method is used, with metal supports 2 connected to the concrete base 1. This insulation and waterproofing method includes the following steps:

[0026] Step 1: Apply primer 3 to the top of the concrete base layer 1 and the outer periphery of the metal support 2;

[0027] Step 2: Apply a first waterproof layer to the top of the concrete base layer 1 and the outer periphery of the metal support 2, so that the first waterproof layer covers the base treatment agent 3;

[0028] Step 3: Construct the insulation layer 7 on top of the first waterproof layer on the concrete base 1, so that the insulation layer 7 adheres to the first waterproof layer below the metal support 2.

[0029] Specifically, the thickness of the insulation layer 7 is less than the height of the metal support 2.

[0030] Step 4: Apply a second waterproof layer to the top of the insulation layer 7 and around the outer periphery of the first waterproof layer on the upper part of the metal support 2;

[0031] Step 5: Apply a protective layer on top of the second waterproof layer.

[0032] By setting the first waterproof layer and the second waterproof layer inside the insulation layer 7, and together completely covering the concrete base 1 and the metal support 2, a fully sealed insulation and waterproof environment is formed, which improves the roof insulation and waterproof effect.

[0033] Specifically, when performing step 2 above, when laying the first waterproof layer at the inside corner between the concrete base 1 and the metal support 2, an arc treatment of R=100 is made.

[0034] Preferably, the first waterproof layer includes a non-curing rubber asphalt waterproof coating 4 and a self-adhesive polymer-modified bitumen waterproof membrane 6. When performing step 2 above, the non-curing rubber asphalt waterproof coating 4 is heated to 150-200 degrees Celsius and evenly brushed onto the top of the base treatment agent 3, and then the self-adhesive polymer-modified bitumen waterproof membrane 6 is laid on the non-curing rubber asphalt waterproof coating 4.

[0035] Specifically, when laying the self-adhesive polymer-modified bitumen waterproof membrane 6, multiple layers are laid, with adjacent layers of the self-adhesive polymer-modified bitumen waterproof membrane 6 overlapping each other. The overlap length is not less than 80mm. The overlap joint is sealed internally and externally with non-curing rubber bitumen waterproof coating 4. A long-spouted bottle is used for external sealing. Polyurethane weather-resistant sealant is used to seal the end of the self-adhesive polymer-modified bitumen waterproof membrane 6.

[0036] Specifically, at locations such as pipes penetrating the slab and internal / external corners, an additional layer of this self-adhesive polymer-modified bitumen waterproof membrane 6 is applied as an additional layer 5.

[0037] Since the pipes penetrating the plate, the inside and outside corners are waterproof nodes, this additional layer 5 is added. The double-layer waterproofing improves the overall waterproofing effect.

[0038] Preferably, before performing step 3 above and after performing step 2 above, a modified bitumen adhesive is applied to the top of the first waterproof layer, and during the performance of step 3 above, the insulation layer 7 is bonded to the first waterproof layer.

[0039] A modified bitumen adhesive is applied to the top of the first waterproof layer to provide a bonding base for the insulation layer 7.

[0040] Preferably, the insulation layer 7 includes multiple foam glass insulation boards. When performing step 3 above, the multiple foam glass insulation boards are spliced ​​together in a staggered manner, and the modified asphalt adhesive is fully applied to each splice joint.

[0041] By using foam glass insulation boards instead of traditional rock wool as insulation layer 7, the insulation effect is improved. In addition, by splicing multiple foam glass insulation boards in a staggered manner, the overall stability of insulation layer 7 is improved.

[0042] Specifically, for polygonal roofs or arc-shaped sections, the foam glass insulation board is laid horizontally and the corners are cut and chamfered according to the roof slope.

[0043] Preferably, the second waterproof layer includes an asphalt-based liner and an SBS modified bitumen waterproof membrane 8. When performing step 4 above, the asphalt-based liner is connected to the top of the insulation layer 7 and the upper part of the metal support 2, and the SBS modified bitumen waterproof membrane 8 is adhered to the top of the asphalt-based liner using a hot-melt method.

[0044] By adopting a fully adhesive bonding process, the first waterproof layer, the thermal insulation layer 7, and the second waterproof layer are bonded together to form a fully sealed thermal insulation and waterproof whole, thereby improving the thermal insulation and waterproof effect.

[0045] Specifically, when laying the SBS modified bitumen waterproof membrane 8, multiple layers are used. Adjacent SBS modified bitumen waterproof membranes 8 overlap each other, and the short side overlaps are staggered. The long side overlap length and the short side overlap width are both not less than 100mm, and the short side overlap staggered length is not less than 500mm.

[0046] By using the above-mentioned laying method, the integrity of the multiple layers of SBS modified bitumen waterproof membrane 8 after laying is ensured, and the waterproofing effect is improved.

[0047] Specifically, when laying the SBS modified bitumen waterproof membrane 8, if the roof slope is less than 3%, it should be laid parallel to the ridge; if the roof slope is between 3% and 15%, it should be laid parallel to or perpendicular to the ridge; if the roof slope is ≥15%, it should be laid in the direction of water flow.

[0048] Preferably, the second waterproof layer further includes a two-component epoxy primer 9 applied to the top of the SBS modified bitumen waterproof membrane 8 and a polyurea waterproof coating 10 sprayed onto the top of the two-component epoxy primer 9.

[0049] The overall waterproofing effect is further improved by applying the epoxy resin primer and the polyurea waterproof coating 10 to the SBS modified bitumen waterproof membrane 8.

[0050] Preferably, when spraying the polyurea waterproof coating 10, multiple sprayings are used, such that the spraying direction of the next spray is perpendicular to the spraying direction of the previous spray, and the spraying range of the next spray covers at least 50% of the spraying range of the previous spray.

[0051] By adopting the above-mentioned spraying process, the polyurea waterproof coating 10 is sprayed more evenly, thus improving the waterproofing effect.

[0052] Specifically, the spraying thickness of the polyurea waterproof coating 10 is not less than 2 mm.

[0053] Preferably, the protective layer includes a weather-resistant polyurethane coating, which is applied by roller to the top of the second waterproof layer during step 5, with a coating thickness of not less than 0.1 mm.

[0054] By applying this weather-resistant polyurethane coating, the second waterproof layer is protected from corrosion by sunlight and rain.
