Description
Technical field
The invention belongs to waterproof technology of roofing field, specifically, relate to a kind of zero stress and stitch wide self-adapting type roofing preset slot waterproofing system and construction method thereof.
Background technology
Due to the impact of variations in temperature, uneven settlement of foundation and seismic factors, can make building that crack or destruction occur, therefore house being divided into several independently parts in advance when designing, each several part can freely be changed, and this preset slot vertically separated by building is called deformation joint.Wall body structure is divided into separately independently section by the setting of deformation joint.Deformation joint comprises Temperature Joint, settlement joint and aseismic joint three kinds, is described as follows:
(1) for preventing building unit because of variations in temperature, expanding with heat and contract with cold makes house occur crack or destruction, along building length direction reserved vertical clearance gap separated by a distance.This seam arranged because of variations in temperature is called temperature joint or shrinkage joint.Shrinkage joint spacing is relevant with the classification of body of wall, and particularly relevant with the type of roof and floor, the width at shrinkage joint is generally 20-30mm.
(2) for prevent building each several part due to uneven settlement of foundation cause house destroy set by vertical lap seam be called settlement joint.The width of settlement joint is relevant with ground situation and building height, the building that ground is more weak, the possibility of depression is higher, and the slant range produced after depression is larger, its settlement joint width is generally 30-70mm, and its seam of the building on soft foundation widely should suitably increase.
(3) the regional planted agent being 7-9 degree at seismic fortification intensity arranges aseismic joint, and generally aseismic joint is only arranged above on basis, but aseismic joint should be coordinated to arrange with shrinkage joint and settlement joint, accomplishes that a seam is multiplex.The width of aseismic joint, gets 50-70mm by the difference of design intensity in multilayer brick wall house; In multi-story-frame building, when depth of building is less than or equal to 15m, stitching wide is 70mm; When depth of building is more than 15m, design intensity 7 degree, building often increases 4m, and stitch widely increases 20mm on 70mm basis; Design intensity 8 degree, building often increases 3m, and stitch widely increases 20mm on 70mm basis; Design intensity 9 degree, building often increases 2m, and stitch widely increases 20mm on 70mm basis.
In addition, monolithic roofing refers to the density of dependence structural element self or adopts rigidity water-proofing material and flexible joint Material cladding as waterproofing course to reach a class water-proof roofing of building waterproof object, mainly be applicable to the roof waterproof that classification of waterproof is III grade, also can be used as I, II grade of roofing multi layer waterproof set up defences in one waterproofing course; Be not suitable for the building roof by larger vibration or impact.
Monolithic roofing mainly comprises common pea gravel concreten water-proof roofing, expansive concrete water-proof roofing, steel fibrous concrete water-proof roofing, prestressed concrete water-proof roofing and block monolithic roofing etc., and wherein former three is most widely used." Technical code for roof engineering " (GB50345-2012) has all done detailed regulation to this three: common pea gravel concreten roofing: thick 40mm, C20 concrete, adds reinforced mesh, encapsulant pointing; Expansive concrete roofing: add expansion agent in concrete, under constrained condition, makes the tensile stress that the compressive stress compensating concrete of generation produces due to drying shrinkage, to avoid plate surface crack; Steel fibrous concrete roofing: the short and discontinuous steel fibre mixing non-directional distribution in roofing pea gravel concreten, distributes in three-dimensional random, improves concrete crack resistance.
Rely on the density of concrete self or adopt expansive concrete, prestressed concrete, and coordinating certain component measure, monolithic roofing reaches waterproof object.Its main component measure is: roofing has certain gradient, is convenient to rainwater and gets rid of in time; Increase reinforcing bar; Separation layer is set.In addition, for avoiding producing crack under the factor impacts such as External Force Acting, warm and humid change, deck distortion, monolithic roofing should be considered in the design process: preferentially select the materials and structures form that cracking resistance is good; Strengthen deck rigidity by various measure, reduce the thermal stresses of waterproofing course, reduce concrete shrinkage; Dividing joint is set and ensures that monolithic roofing is in temperature further, unlikely cracking under the condition of humidity change.
Dividing joint is total shrinkage value for reducing large area waterproofing course and thermal stresses, avoids because deck displacement and temperature, humidity change cause waterproof layer cracking to cause seepage and reserved gap, usually arranges according to the shape of flat roof deck, size and structure.
Common pea gravel concreten and expansive concrete waterproofing course, the width of dividing joint is preferably 5-30mm.Dissimilar rigid waterproof layer dividing joint spacing calculates except needs (generally should not be greater than 6m) except meeting, also should at roof structure deformation sensitive place, ridge and roof drainage direction change place, the junction of waterproofing course and outstanding roof structure, waterproofing course and load-bearing or non-bearing parapet or gable the position such as junction dividing joint is set.In addition, dividing joint planted agent pointing encapsulant, to ensure its water proofing property and to adapt to roof-base distortion.
A large amount of engineering experience shows: the roof surface crack that warm and humid change causes, preset slot arrange unreasonable, Filling Technology control tight, the cementation of fissures is not full, caulking material is second-rate, filling with caulking material, be separated the preset slot place waterproof weakness caused with monolithic roofing material be the principal element restricting roof waterproof performance.So the quality of waterproof ability to the performance determining roof waterproof of preset slot is most important.
For improving roofing preset slot place waterproof ability, existing Patents technical scheme is open, as application number 200910206901.5, the applying date is on October 20th, 2009, invention and created name is: waterproof buckle plate of roof expansion joint, and this application case is protected both sides at the bottom of edge and plate by both sides at the bottom of plate, at the bottom of plate and protected along forming with the groove formed at the bottom of plate; By being overlapped on the buckle closure seamed edge reserved roof stretching seam both sides realized to roof stretching seam.This application case substitutes to a certain extent fills with filleting technique thus avoids the factors such as Filling Technology controls sternly, the cementation of fissures is not full, caulking material is second-rate to have a negative impact to shrinkage joint waterproof ability, but, still there is following problem in this application case: (1) buckle and monolithic roofing storeroom only simply fasten, the two deformation in outdoor environment, will cause buckle to produce with roofing materials and seriously be separated.In addition, make if buckle is rigid material, also may occur that the cracking of buckle even ruptures; (2) even if realize compatibility of deformation by relative configurations between buckle and roofing materials, roofing materials expands or shrinks under the effect of factors such as being heated, buckle material (rigid material or flexible material) both sides are opened thereupon or are compressed, buckle is subject to a stress, because at the bottom of the plate of buckle and both sides at the bottom of plate are protected be rectangle along cross section, deformability is less, under cyclic stress effect, also can produce fatigue failure.
