Description
Technical Field
The invention relates to the field of roof waterproofing, in particular to a reverse closing method for a waterproof roll of a roof.
Background
Parapet walls are usually arranged around a roof of a building, and the parapet walls are short walls around the roof, so that on one hand, a high-altitude falling accident can be prevented when people move on the roof; on the other hand, the waterproof structure can provide a structural foundation for roof waterproofing and outer wall decoration. When the roof waterproof layer is constructed, the waterproof coiled material is laid at the position of the parapet wall and needs to be closed. The conventional method comprises the following steps: the waterproof coiled material is turned upwards to a position with a certain height of the parapet wall, then the cut edge of the waterproof coiled material is fixed by a pressing strip and a fastener, and finally a full-length sealant is smeared along the cut edge of the waterproof coiled material and the edge of the pressing strip for sealing.
Because waterproofing membrane closes up in parapet's side, waterproofing membrane's incision edge and layering are fixed in the side of parapet. On one hand, under the long-time action of self gravity and thermal expansion and cold contraction, the relative deformation is easy to occur between the edge of the notch and the pressing strip; on the other hand, the batten and the fastener are easy to generate rust corrosion after long-term exposure, so that the fastening failure of the local closing-in position is caused, and further, a gap is generated between the waterproof coiled material and the side surface of the parapet wall. And the sealant on the topmost layer is also exposed outside, so that when the sealant is aged and cracked due to long-time exposure, the moisture on the wall surface of the parapet can permeate the sealant and further flow to the roof structure layer through a gap between the waterproof coiled material and the parapet, thereby causing roof leakage and reducing the durability and reliability of the roof waterproof engineering. Further, when outdoor moisture leaks between the waterproof roll and the structural layer through a gap at the waterproof roll closing port, a water channeling channel may be formed, so that the indoor leakage point is inconsistent with the outdoor leakage point, the actual leakage point is not easily determined, and the maintenance is difficult.
Disclosure of Invention
The invention aims to overcome at least one defect of the prior art, and provides a reverse closing method of a waterproof roll of a roof, which is used for solving the problem that a seam is easily generated at the closing position of the waterproof roll on a wall body to cause leakage, so that the durability and reliability of roof waterproof engineering are improved.
The technical scheme adopted by the invention is that the reverse closing-in method of the waterproof coiled material of the roof comprises the following steps:
s1, adhering one end of a first coiled material to the upper surface of a wall body of a roof by using a first sealant; the cut edge of the first coiled material faces the inner side of the wall body, and the front face of the first coiled material faces downwards;
s2, fixing the first coiled material on the upper surface of the wall body for the second time by using a first pressing strip and a first fastener at the edge of the cut of the first coiled material;
s3, folding the first coiled material along the outline of the first pressing strip, wherein the first coiled material wraps the surface of the first pressing strip;
s4, laying the first coiled material along the upper surface and the side surface of the wall body, and extending the first coiled material to the roof; the first coiled material is lapped and fixed on the second coiled material on the roof.
In this scheme, use the thickness direction of wall body as width direction, use the wall body to be close to one side of roofing as the inboard, use the construction face of first coil of material as the back. The closing-up position of the first coiled material is provided with a fixed section, a turnover section and a covering section. The fixed section is a first coiled material pressed by the first pressing strip, the turnover section is a first coiled material turned over along the side profile of the first pressing strip, and the covering section is a first coiled material covering the rest profiles of the first pressing strip. The slit edge of the first web is folded over on its own inside, i.e. the reverse cuff. In addition, along the length direction of wall body, first layering, first coiled material, second coiled material all have fixed length, and a plurality of first layering is the concatenation each other, and a plurality of first coiled material is overlap joint each other, and a plurality of the second coiled material is also overlap joint each other. For short walls, the first coil may also be a full strip.
In the scheme, the closing position of the first coiled material is changed to the upper surface of the wall body, and the closing position sequentially comprises a first sealant, a fixed section of the first coiled material, a first pressing strip and a covering section of the first coiled material from bottom to top. First, in one aspect, the first sealant serves as a face seal while adhering the first web, the first sealant covering the surface of the fixed length of the first web. Compared with a line sealing mode, namely a mode of only coating the edge of the cut of the first coiled material, the surface sealing can still keep the sealing effect when local cracks are generated, and the sealing reliability can be effectively improved. On the other hand, the first sealant is located between the surfaces of the first coiled material and the wall body, and is not directly exposed to the external environment, so that the problem of aging and cracking of the sealant caused by long-time exposure to the sun and rain can be avoided, and the sealing durability can be effectively improved. Furthermore, in one aspect, the first coil is supported by the upper surface of the wall to counteract the effects of its own weight. The cut edge of the first coiled material is not pulled by the gravity of the first coiled material, is not easy to generate fold deformation, and can be kept to be smoothly adhered to the upper surface of the wall body. On the other hand, the fixed section and the folded section of the first coiled material form a folding structure (such as a right-angle folding), which increases the deformation inertia of the edge of the first coiled material, and the edge or the fixed section can be still flatly adhered to the upper surface of the wall body even under the condition of thermal expansion and cold contraction of the first coiled material or uneven compression of the first batten. Secondly, on the one hand, the first pressing strip is also supported by the upper surface of the wall body so as to counteract the influence of the gravity of the first pressing strip, the first pressing strip cannot generate bending deformation, and the first pressing strip can be always attached to and fastened with the fixed section of the first coiled material. On the other hand, the appearance profile of the first pressing strip and the first fastening piece on the first pressing strip are wrapped by the first coiled material, so that the moisture of the external environment can be effectively isolated, the first pressing strip or the first fastening piece is prevented from being rusted, and the local fastening failure of the first pressing strip to the first coiled material is further avoided. Finally, the closing-up position of the first coiled material is located on the upper surface of the wall body, and compared with the side surface of the wall body, moisture falling on the closing-up position flows away along the surface of the first coiled material and the upper surface of the wall body under the action of gravity, and cannot permeate into the first sealant. Thus, even if there are a few gaps (gaps of the first sealant or gaps of the first web and the wall) at the closing position, no leakage will result.
This scheme is through the last surface of changing the binding off position of first coiled material to the wall body, and first sealed glue is paintd to the canned paragraph of first coiled material, and first coiled material turns over a means such as book and wrap up first layering to guarantee the sealed effect of binding off position and guarantee that first coiled material can laminate wall body surface all the time, solved the binding off position of waterproofing membrane on the wall body and produced the problem that the gap leads to the seepage easily, reach the durability and the reliability that promote the roofing waterproofing engineering.
Preferably, the closing position of the first web needs to be further processed according to step S5, which is as follows:
s5, coating a second sealant at the turning position of the first coiled material on the upper surface of the wall body, wherein the second sealant covers between the side face of the first coiled material and the upper surface of the wall body.
In one aspect, the first sealant is located between the first coil and the wall, but one side of the first sealant located at the folded section of the first coil is still exposed. The second sealant is smeared along the side so as to completely seal the first sealant, and the first sealant is prevented from aging and cracking. On the other hand, the second sealant covers between the turning section of the first coiled material and the upper surface of the wall body, which is equivalent to a second sealing defense line at the closing position of the first coiled material, so that the sealing effect at the closing position is further improved by a redundant design. When the second sealant is coated, no opening and no leakage of the sealant are ensured.
Further, the smearing height of the second sealant is more than or equal to 1/2 of the height of the side face of the first coiled material; the width of the second sealant is greater than or equal to 1/2 of the height of the side face of the first coiled material. The effect of redundant sealed design is guaranteed through injecing height and the width that the sealed glue of injecing the second paintd to this scheme.
Preferably, the step S1 specifically includes: firstly, a position reference mark is made on the upper surface of a wall body of a roof, then first sealant is uniformly coated on one side of the position reference mark, and finally, a first coiled material is bonded on the upper surface of the wall body along the position reference mark.
The position reference mark is used as a reference of the closing position of the first coil, so that the construction positions of the first sealant, the first coil and the first pressing strip can be confirmed in an auxiliary mode, and the construction effect is guaranteed. The first sealant is smeared along the position reference mark, and the first coil is bonded along the position reference mark, so that the surface sealing of the fixed section of the first coil in the length direction can be kept uniform, and the width of the surface sealing is ensured. The first pressing strips are installed along the position reference marks, so that the first pressing strips can be spliced into a long straight line, and the first rolled material is prevented from being folded after being folded and wrapped.
Further, the width of the first sealant for coating is larger than the width of the first pressing strip and is larger than or equal to the width of the first coiled material pressed by the first pressing strip. The width of the first pressing strip is not less than that of the fixed section of the first coiled material, so that the first pressing strip can be ensured to completely press and fasten the fixed section. The cut edge of the first coiled material, namely the cut edge of the fixed section is positioned below the first pressing strip, so that the cut edge can be prevented from being wrinkled and peeled off at a later date, and a gap can be prevented from being formed between the first coiled material and the wall surface. The width that first sealed glue was paintd is greater than the width of first layering, makes first layering to the fastening installation back of first coiled material, and the both ends of first sealed glue can partially spill over to the both sides of the canned paragraph of first coiled material and the both sides of first layering, forms the sealed binding off of enclosed type, strengthens the sealed effect of first sealed glue.
Preferably, the step S2 further includes: along the length direction of the wall body, a plurality of first pressing strips are spliced with one another, and a plurality of first rolled materials are mutually overlapped; the splicing openings between the first pressing strips and the lap joint positions between the first rolled materials are staggered.
Two ends of the first pressing strips are fixed through first fasteners respectively, and when the two first pressing strips are spliced, the first fasteners are arranged on two sides of the splicing port. When two rolls of the first web are overlapped, the first web is partially overlapped. When the splice mouth of first layering was located the overlap joint position of first coiled material, the effect of fixed splice mouth position and fixed first coiled material need be played simultaneously to the first fastener of this position, and two-layer first coiled material need be passed to first fastener more difficultly, leads to the splice mouth of first layering to produce the dislocation when fixed easily. Further, for the first pressing strip pressing the lap joint position of the first coiled material, the first fastening piece on the first pressing strip can be arranged after properly avoiding the lap joint position.
In the scheme, the fixing modes of the first coiled material and the second coiled material on the roof are various, and one mechanical fixing method can refer to the following steps:
s6, fixing the first coiled material and the second coiled material on the roof by using a second pressing strip and a second fastener at the lap joint position of the first coiled material and the second coiled material;
and S7, covering the second pressing strip and the second fastening piece by using a third coiled material, wherein two sides of the third coiled material are fixedly connected with the first coiled material and the second coiled material respectively.
Preferably, the first web is overlapped below the second web; the width of the lap joint of the first coiled material and the second coiled material is larger than the width of the second pressing strip.
The second coiled material is laid to the lower edge of the wall body along the roof, and the second coiled material is overlapped above the first coiled material. The second web maintains a continuous fluid-directing surface to prevent moisture from penetrating through the gap at the overlap of the first web and the second web. Compared with a bonding mode, the mode of fixing the pressing strips is adopted, and the first coiled material and the second coiled material can be simply and reliably fixed on the roof by the fasteners at one time. The third coiled material covers the second pressing strip and the second fastening piece, so that the second pressing strip and the second fastening piece can be prevented from being rusted, and further the fastening failure of the second pressing strip on the first coiled material and the second coiled material is avoided.
Preferably, the first sealant and/or the second sealant are silicone weather-resistant adhesives.
Preferably, the first roll, the second roll and the third roll are all TPO waterproof rolls, wherein the second roll is of P type or L type, and the first roll and the third roll are of H type. Wherein, H type is homogeneous coiled material, and does not adopt inner reinforced material or backing material, and the coiled material is easy to bend and adhere to the construction surface. The first coil material of H class makes it easily turn over and wrap up first layering, and the third coil material of H class makes it easily cover the second layering. The second coiled material of the mechanical fixing system is of a P type, and the second coiled materials of the full-adhesion system and the empty-paving system are of an L type. Further, first coiled material, second coiled material and third coiled material are TPO self-adhesion waterproofing membrane to convenient construction.
Compared with the prior art, the invention has the beneficial effects that:
this scheme is through the last surface of changing the binding off position of first coiled material to the wall body, and first sealed glue is paintd to the canned paragraph of first coiled material, and first coiled material turns over means such as rolling over and wrap up first layering to guarantee the sealed effect of binding off position and guarantee that first coiled material can laminate wall body surface all the time, solved waterproofing membrane and produced the problem that the gap leads to the seepage easily in the binding off position on the wall body, reach the durability and the reliability that promote the roofing waterproof engineering.
The second that this scheme was sealed through sealed glue realization first coil material binding off position is sealed line of defence to the sealed effect of binding off position is further promoted in redundant design.
According to the scheme, the first sealing glue, the first pressing strip and the width relation of the fixed section of the first coiled material are used for ensuring that the first pressing strip presses and fixes the fixed section completely, so that the phenomenon that the edge of a notch of the fixed section is wrinkled and peeled in the future is avoided; meanwhile, the two ends of the first sealant can partially overflow to the two sides of the fixed section of the first coiled material and the two sides of the first pressing strip, so that the surrounding sealing closing-up is formed, and the sealing effect of the first sealant is enhanced.

s2, fixing the first coiled material 10 on the upper surface of the wall body 2 for the second time by using a first pressing strip 6 and a first fastener 8 at the edge of the cut of the first coiled material 10;
s3, folding the first coiled material 10 along the outline of the first pressing strip 6, wherein the first coiled material 10 wraps the surface of the first pressing strip 6;
s4, laying the first coiled material 10 along the upper surface and the side surface of the wall body 2 and extending the first coiled material to the roof 1; the first coil 10 overlaps the second coil 20 fixed to the roof 1.
In the scheme, the thickness direction of the wall body 2 is taken as the width direction, one side of the wall body 2 close to the roof 1 is taken as the inner side, and the construction surface of the first coiled material 10 is taken as the back surface. The first web 10 has a necked position with a fixed section 11, a folded section 12 and a cover section 13. The fixed section 11 is a first coiled material 10 pressed by the first pressing bar 6, the folding section 12 is the first coiled material 10 folded along the side profile of the first pressing bar 6, and the covering section 13 is the first coiled material 10 covering the rest profiles of the first pressing bar 6. The slit edge of the first web 10 is folded over on itself, i.e. the reverse cuff. In addition, along the length direction of the wall body 2, the first pressing strips 6, the first coiled materials 10 and the second coiled materials 20 all have fixed lengths, a plurality of the first pressing strips 6 are spliced with one another, a plurality of the first coiled materials 10 are overlapped with one another, and a plurality of the second coiled materials 20 are also overlapped with one another.

Firstly, on the one hand, the first sealant 4 serves as a face seal while adhering the first web 10, and the first sealant 4 covers the surface of the fixed length 11 of the first web 10. Compared with the line sealing mode, namely the mode of only coating the cut edge of the first coiled material 10, the surface sealing can still maintain the sealing effect when local cracks are generated, and the sealing reliability can be effectively improved. On the other hand, the first sealant 4 is located between the first coil 10 and the surface of the wall 2, and is not directly exposed to the external environment, so that the problem of aging and cracking of the sealant caused by long-time exposure to the sun and rain can be avoided, and the sealing durability can be effectively improved. Furthermore, in one aspect, the first coil 10 is supported by the upper surface of the wall 2 to counteract the effects of its own weight. The cut edge of the first coil 10 is not pulled by its own weight, is not easily deformed by wrinkles, and can be kept flat and adhered to the upper surface of the wall 2. On the other hand, the fixed segment 11 and the folded-over segment 12 of the first coil 10 form a folded structure (e.g., a right-angle fold), which increases the moment of inertia of the edge of the first coil 10, and the edge or the fixed segment 11 remains adhered to the upper surface of the wall 2 smoothly even in the case of thermal expansion and contraction of the first coil 10 or uneven compression of the first bead 6. Secondly, on the one hand, the first pressing strip 6 is also supported by the upper surface of the wall body 2 to counteract the influence of the gravity thereof, the first pressing strip 6 cannot generate bending deformation, and the fixing section 11 of the first coiled material 10 can be always attached and fastened. On the other hand, the outer contour of the first bead 6 and the first fastening member 8 thereon are wrapped by the first coil 10, which can effectively isolate the moisture of the external environment, prevent the first bead 6 or the first fastening member 8 from rusting, and further prevent the first bead 6 from partially fastening the first coil 10. Finally, the closing position of the first coiled material 10 is located on the upper surface of the wall body 2, and compared with the side surface of the wall body 2, moisture falling on the closing position flows away along the surface of the first coiled material 10 and the upper surface of the wall body 2 under the action of gravity and cannot permeate into the first sealant 4. Thus, even if there is a small gap (gap of the first sealant 4 or gap of the first web 10 and the wall 2) at the closing position, no leakage is caused.
This scheme is through changing the binding off position with first coiled material 10 to the upper surface of wall body 2, and first sealed glue 4 is paintd to the canned paragraph 11 of first coiled material 10, and first coiled material 10 turns over a means such as rolling over and parcel first layering 6 to guarantee the sealed effect of binding off position and guarantee that first coiled material 10 can laminate wall body 2 surfaces all the time, solved the binding off position of waterproofing membrane on the wall body and produced the problem that the gap leads to the seepage easily, reach the durability and the reliability that promote the roofing waterproof engineering.
Specifically, in step S2, the first bead 6 is a U-shaped bead, and the first fastening member 8 may be a rivet or an expansion bolt. The first fastening member 8 passes through the first bead 6, the first coil 10 and the first sealant 4 and is fixed to the upper surface of the wall body 2. The first fasteners 8 are distributed at intervals of 200 mm and 300mm toward the center with both ends of the first compression bar 6 as a reference. In step S3, the first web 10 needs to be kept flat when being folded and wrapped around the first bead 6, so as to avoid wrinkles. In step S4, the construction method and the construction requirement for laying the first coil 10 along the upper surface and the side surface of the wall 2 can refer to the construction method and the construction requirement for laying the second coil 20 on the roof 1.
Preferably, the necking position of the first web 10 is further processed according to step S5, as follows:
s5, coating a second sealant 5 at the turning position of the first coiled material 10, which is positioned on the upper surface of the wall body 2, wherein the second sealant 5 covers between the side surface of the first coiled material 10 and the upper surface of the wall body 2.
On the one hand, the first sealant 4 is located between the first roll 10 and the wall 2, but the side of the first roll 10 located at the folded section 12 is still exposed. The second sealant 5 is applied along the side to completely seal the first sealant 4, thereby preventing the first sealant 4 from aging and cracking. On the other hand, the second sealant 5 covers between the folded section 12 of the first coiled material 10 and the upper surface of the wall body 2, which is equivalent to the second sealing line at the closing position of the first coiled material 10, so as to further improve the sealing effect at the closing position by a redundant design. When the second sealant 5 is coated, no opening and no leakage of the sealant are ensured.
Further, the height of the second sealant 5 is greater than or equal to 1/2 of the height of the side surface of the first coil 10; the width of the second sealant 5 is greater than or equal to 1/2 which is the height of the side surface of the first coil 10. The effect of redundant sealed design is guaranteed to this scheme through the height and the width of injecing sealed 5 paintings of second. Specifically, the section of the second sealant 5 after being coated is semicircular, and the radius of the section is slightly smaller than the height of the side surface of the first coiled material 10. The semi-circular second sealant 5 ensures that it has sufficient thickness to effectively resist its own aging cracking.
As shown in fig. 1 and 4, preferably, the step S1 specifically includes: firstly, a position reference mark 3 is made on the upper surface of a wall body 2 of a roof 1, then a first sealant 4 is uniformly coated on one side of the position reference mark 3, and finally a first coiled material 10 is bonded on the upper surface of the wall body 2 along the position reference mark 3.
The position reference mark 3 is used as a reference of the closing position of the first coil 10, and can assist in confirming the construction positions of the first sealant 4, the first coil 10 and the first bead 6, and ensuring the construction effect. The first sealant 4 is coated along the position reference mark 3, and the first web 10 is bonded along the position reference mark 3, so that the surface sealing of the fixed section 11 of the first web 10 in the length direction can be kept uniform, and the width of the surface sealing is ensured. The first pressing strips 6 are arranged along the position reference marks 3, so that the plurality of first pressing strips 6 can be spliced into a long straight line, and the first coiled material 10 is prevented from being folded around the first coiled material after being folded and wrapped.
Specifically, the position reference mark 3 may be a reference line formed by a bullet line method, or may be a reference symbol marked by a marker. The first sealant 4 is applied along one side of the position reference mark 3 during both the application and the bonding of the first web 10, and cannot cover the position reference mark 3.
As shown in FIG. 2, further, the width of the first sealant 4 applied is larger than the width of the first bead 6 and is larger than or equal to the width of the first coiled material 10 below the first bead 6. The width of the first pressing strip 6 is not less than the width of the fixing section 11 of the first coiled material 10, so that the first pressing strip 6 can be ensured to completely press and fix the fixing section 11. The cut edge of the first web 10, i.e. the cut edge of the fixing section 11, is located below the first bead 6, so as to avoid that the cut edge will wrinkle and peel later, resulting in a gap between the first web 10 and the surface of the wall 2. The width that first sealed glue 4 was paintd is greater than the width of first layering 6, makes first layering 6 fasten the installation back to first coil of material 10, and the both ends of first sealed glue 4 can partially overflow over to the both sides of the canned paragraph 11 of first coil of material 10 and the both sides of first layering 6, forms the sealed binding off of surrounding type, strengthens the sealed effect of first sealed glue 4.
Specifically, based on the width of the first bead 6, the fixed section 11 of the first roll 10 is narrower than the fixed section by 0-2mm, and the width of the first sealant 4 is wider than the fixed section by 0-2 mm. During construction, the first sealant 4 is aligned with the position reference mark 3 and smeared, the first coil 10 deviates from the position reference mark by 0-2mm and is bonded, and the first pressing strip 6 is aligned with the position reference mark 3 and is installed. When the first sealant 4 is coated, no opening leakage phenomenon is ensured.
As shown in fig. 4, preferably, the step S2 further includes: along the length direction of the wall body 2, a plurality of first pressing strips 6 are spliced with one another, and a plurality of first rolled materials 10 are overlapped with one another; the splicing openings between the first pressing strips 6 and the overlapping positions between the first rolled materials 10 are staggered.
The two ends of the first pressing strip 6 are fixed through the first fastening pieces 8 respectively, and when the two first pressing strips 6 are spliced, the first fastening pieces 8 are arranged on the two sides of the splicing port. When two rolls of the first web 10 overlap, the first web 10 is partially overlapped. When the splice mouth of first layering 6 was located the overlap joint position of first coil of material 10, the effect of fixed splice mouth position and fixed first coil of material 10 need be played simultaneously to first fastener 8 of this position, and first fastener 8 needs to pass two-layer first coil of material 10 harder, leads to the splice mouth of first layering 6 to produce the dislocation when fixed easily. Further, for the first bead 6 pressing the overlapping position of the first web 10, the first fastening member 8 thereon can be disposed after properly avoiding the overlapping position.

The second web 20 maintains a continuous fluid-guiding surface to prevent moisture from penetrating through the gap at the overlapping position of the first web 10 and the second web 20. Compared with the bonding mode, the mode of fixing by the pressing strips is adopted, and the first coiled material 10 and the second coiled material 20 can be simply and reliably fixed on the roof 1 by the fasteners at one time. The third coiled material 30 covers the second pressing strip 7 and the second fastening piece 9, so that the second pressing strip 7 and the second fastening piece 9 can be prevented from being rusted, and further the fastening failure of the second pressing strip 7 on the first coiled material 10 and the second coiled material 20 can be avoided.
Specifically, the roof 1 is a metal roof 1, the second pressing strip 7 is a U-shaped pressing strip, and the second fastening piece 9 is a screw. The second batten 7 is arranged close to the lower edge of the wall 2. The second fastening piece 9 passes through the second batten 7, the second coiled material 20 and the first coiled material 10 in sequence to be fixed on the metal roof 1. The second fasteners 9 are distributed at intervals of 200 mm and 300mm toward the center with both ends of the second bead 7 as a reference.
