Abstract
The utility model relates to an anti-cracking and anti-permeability type roof flashing composite layer which is formed by a cement mortar leveling layer, a polymer anti-cracking mortar bottom layer, a flexible waterproof roll and a polymer anti-cracking mortar surface layer which are paved on the connection face of a roof and a vertical wall in sequence. At least one reinforcement anti-cracking mesh is buried in the polymer anti-cracking mortar bottom layer and the polymer anti-cracking mortar surface layer respectively. The anti-cracking and anti-permeability type roof flashing composite layer can prevent leakage and permeability, can avoid cracks, hollow phenomena and leakage caused by expansion and contraction at the roof flashing position when the environment temperature changes, and is good in flashing effect.
Description
Technical field
The utility model relates to a kind of roofing flashing composite bed in the building engineering field, particularly a kind of roofing waterproofing and anti-leakage type roofing circular arc flashing composite bed.
Background technology
In the building; parapet, elevator machine room wall, cornice, to comprise facade be the stress concentration portion position with the body of wall junction that horizontal plane joins for height roofing wall wall etc.; easily be subjected to rain drop erosion or former thereby ponding because of other; in the course of time; can cause seepage; therefore must take waterproof measure, this waterproof measure in the building corner is referred to as " flashing ", with all the other local waterproofing courses (being unlikely to into water) of protection roofing.The method of common usefulness is coated with the flashing composite bed on the metope of building corner both sides and roofing.At present, roofing flashing composite bed is by bottom conventional cement mortar layer, middle level waterproof roll and upper strata conventional cement mortar layer compound composition.Because conventional cement mortar is rigid body after solidifying, tensile strength is low, after engineering is used a period of time, especially under the alternately thermal (temperature difference) stress effect of summer high temperature and winter low temperature, the flashing composite bed produces deformation crack gradually, thereby directly cause cracking, seepage, affect normal usage function, increased engineering and reprocessed cost.
Summary of the invention
The purpose of this utility model provides and a kind ofly is easy to grasp, construction simply, waterproofing and anti-leakage type roofing flashing composite bed efficiently.
Waterproofing and anti-leakage type roofing flashing composite bed, form by spreading successively the cement mortar screeding layer, polymers anti-cracking mortar bottom, flexible waterproof sheet and the polymers anti-cracking mortar surface layer that overlay on roofing and the wall interface, being embedded with respectively at least in the described polymers anti-cracking mortar bottom and in the polymers anti-cracking mortar surface layer, a slice strengthens the anti-crack net sheet.
Described waterproofing and anti-leakage type roofing flashing composite bed is that cambered surface is excessive at roofing and wall rotation angle position.
The height of described flashing composite bed on roofing is along with rotation angle position extends and gradually falls to roofing.
The receipts head of described flexible waterproof sheet upper end is fixed on the wall of flashing face, and the surface seals with waterproof and sealing material.
The cement mortar screeding layer that is positioned at described roofing position is embedded with roofing heat-insulating layer.
The setting of described polymers anti-cracking mortar facing surface is convenient to be filled with fluid sealant in the seam with the flexible dividing joint of temperature.
The utility model roofing flashing composite bed is covered with respectively polymers anti-cracking mortar and imbeds respectively and strengthens the anti-crack net sheet in the both sides of flexible waterproof sheet, the dividing joint that is filled with fluid sealant is set in the polymers anti-cracking mortar surface layer, leakage-proof and seepage-proof, and when variation of ambient temperature, can prevent that roofing flashing position from producing crack, hollowing, Seepage because expanding with heat and contract with cold, rotation angle position is made circular arc, be conducive to the stickup of flexible waterproof sheet, to the tear failure of flexible waterproof sheet, the flashing effect is good under the effect of minimizing thermal stresses.This flashing composite bed can a construction molding, and the flashing height of whole roofing flashing circular arc is consistent, can guarantee roofing integral waterproofing effect, reduces the generation of roof leakage hidden danger, satisfies standard and function instructions for use.Prolong the roof waterproof life-span, improve workmanship, reduce roofing do over again maintenance load and daily management cost.
Description of drawings
Fig. 1 is the cross-sectional view of waterproofing and anti-leakage type roofing circular arc flashing.
Among the figure, 1-cement mortar screeding layer, 2,2 '-polymers anti-cracking mortar layer, 3,3 '-strengthen the anti-crack net sheet, 4-flexible waterproof sheet, 5-dividing joint, 6-roofing is given prominence to structure, 6 '-wall, 7-encapsulant, 8-roofing heat-insulating layer, 9-bear down on one.
The specific embodiment
Fig. 1 represents the structure of roofing flashing composite bed, and wall 6 ' joins mutually with roofing 6, and the top of wall 6 ' is provided with bears down on one.Among the figure, the wall 6 ' of handing-over both sides, limit and be the flashing position with the surface of roofing 6.Roofing flashing composite bed is by following program making: spread at wall 6 ' with the interface of roofing 6 first and cover cement mortar screeding layer 1, wherein be overlying on and imbed insulation layer 8 in the cement mortar on the roofing 6, after the abundant drying of cement mortar, cover bottom polymers anti-cracking mortar layer 2 in its shop, surface, and in the polymers anti-cracking mortar layer, imbed a slice enhancing anti-crack net sheet 3.After bottom polymers anti-cracking mortar layer 2 abundant drying, cover flexible waterproof sheet 4(with waterproof roll 4 hot melts or stick on the surface of polymers anti-cracking mortar layer 2), the receipts head of flexible waterproof sheet 4 upper ends is fixed on the metal bead nail on the wall 6 ' of 10 end openings that bear down on one, receives head and carry out encapsulation process with waterproof and sealing material 7; Repave at flexible waterproof sheet 4 and to cover polymers anti-cracking mortar layer 2 ', imbed equally and strengthen anti-crack net sheet 3 '.The surface of polymers anti-cracking mortar layer 2 ' longitudinally arranges a channel temp dividing joint 5 every 3m, stitches wide and stitch deeply to be 10mm, is filled with fluid sealant in the seam, so far finishes the implementation of waterproofing and anti-leakage type roofing circular arc flashing.
When cement mortar screeding layer 1 is covered in the shop, be paved into cambered surface at roofing 8 and wall 6 ' handing-over position, subsequently each is layer excessive with cambered surface too at this position.
