Description
Technical field
The present invention relates to the water leak-proof structure of architectural deformation joint.
Background technology
Because be subjected to the influence of factors such as variations in temperature, differential settlement and earthquake, building structure inside will produce subsidiary stress, this stress usually makes building produce crack even destroyed.Be the influence of minimizing stress to building, the part at deformation sensitive disconnects structure in advance when design, reserving gaps, and promptly deformation joint has enough deformation spaces and does not make the damaged or generation crack of building to guarantee each part that building is disconnected.According to different design concepts, deformation joint is divided into shrinkage joint, settlement joint, aseismic joint.
Being provided with of deformation joint reduced reluctant deformation crack on a lot of engineerings, guaranteed the safety of structure, if but the seam structure deal with improperly, will use to building again and bring adverse effect.For example, can not adapt to the distortion needs, leak, irritate wind etc.
Along with making constant progress of society, people are to the demand of building not only on the amount of resting on, but the comfortableness of building, exquisite degree are proposed requirements at the higher level.The design of deformation joint is important component part in the architectural design, whether reasonable in design it is directly influence building normally use and build attractive in appearance, in design, should give abundant attention.Yet deformation joint handle to lack reasonability, unsatisfactory in present many engineerings, and deformation joint leaks and causes metope, ceiling stain full of stains or spots, moist, go mouldy, plastering comes off, be seen everywhere, use to the space and brought a lot of inconvenience, the health that has also influenced environment is attractive in appearance.Therefore, inquiring into a kind of durable deformation joint structural scheme rationally is to have active operation significance.
Common flooring deformation joint is constructed as shown in Figure 1 on the engineering at present.This structural scheme ubiquity on actual engineering and is leaked and problem such as poor durability.
Cause the water when mainly reaching ground flushing at ordinary times from rainwater (rainy day is chosen the rainwater on ground, corridor outward) that leaks of deformation joint, it mainly contains two approach along deformation joint seepage: the one, and the deformation joint border leaks; The 2nd, the deformation joint termination leaks.
One. the analysis of leaking of deformation joint border
In structure shown in Figure 1, the waterproof of deformation joint 1 mainly is to work by iron sheet 19, but the in fact this practice can not play real waterproof action.Because although in current standard, require to smear water-proof adhesive, follow closely cement nail after cementing again, yet such requirement is difficult to when practical operation realize, has the possibility of leaking bonding fully at the iron sheet soffit and with the cement mortar upper surface of its handing-over.The permeation pathway of water mainly contains three:
1) exists penetrating passage between iron sheet and screed
Iron sheet is that a kind of semi-rigid material (can not be considered as flexibility fully, so be referred to as semi-rigid), by cementing agent and cement mortar screeding layer bonding, be difficult to reach fully and paste, the deflection deformation of iron sheet and expanding with heat and contract with cold of self also may make itself and adhesive surface be separated from, structure position changing might make that also original just very weak tack coat breaks away between iron sheet and the screed, forms penetrating passage.
2) exist the slit between lid seam cover plate 2 and the edge-protecting angle iron 18
For distortion needs freely, can only bond by an end between lid seam cover plate and the angle steel, at the other end, water just may flow to U type groove along the slit between cover plate and the edge-protecting angle iron, and tack coat destruction also will form penetrating passage.
3) exist the slit between edge-protecting angle iron and the ground surface material
The capillary penetrating passage of surface material self and and edge-protecting angle iron between the slit of the inharmonious formation of distortion all will be penetrating passage.
Like this, a part of water infiltrates peripheral deck along these passages, as metope, ceiling etc.; Another part water then flows in the U-lag, as shown in Figure 1.
Two. the analysis of leaking of deformation joint (U-lag) termination
Because the needs of distortion, galvanized sheet iron U-lag can not shutoff in the termination, partly the flooring water that flows in the U-lag just will be discharged from two ends, so flushing is upstairs suffered disaster, have a strong impact on the normal use of architectural space downstairs.Although current standard proposes can substitute the U-iron skin with the macromolecule coiled material when having ready conditions, yet still is difficult to avoid flowing down of flooring water in the termination.And, if water flows in the U-lag of coiled material, not being provided with because of having to get rid of, long term storage must influence coiled material service life, makes the coiled material cracky, and it is unavoidable to leak.
In addition, because the 22 chance hydro-thermal resistances of pitch flax silk reduce in the U-lag, lose due thermal technology's effect, the thermal property of deformation joint is difficult to guarantee that the actual effect of such structure way has been run counter to the design original intention.And iron sheet is met water and is easily got rusty poor durability; Rubber tile 23 belongs to organic material, easily aging corrosion-vulnerable, and durability is limited.
Summary of the invention
The invention provides a kind of flooring or deformation joint of roof water leak-proof structure, it not only can effectively solve the leakage problems that building flooring or deformation joint of roof cause, and good endurance.
Technical solution of the present invention is characterised in that: the outside portion of deformation joint is provided with the gutter, the deformation joint top is provided with cover plate, the downside outer end of cover plate is provided with the feet that is buckled in the gutter downwards, the upper surface in described gutter is equipped with waterproofing course, the place that described cover plate and feet bottom thereof contact with the gutter is provided with the watertight insulation that is positioned at the waterproofing course upper surface, and the bottom, gutter is provided with the drainage pipe towards underdrainage system.
The present invention in use will have the multiple tracks waterproof to set up defences, it is the fluid sealant that is positioned between the slit of cover plate and building structure that the first road waterproof is set up defences, it can stop the current of roofing or flooring to advance in the gutter preferably, even because a variety of causes causes the inefficacy of setting up defences of the first road waterproof, water also can only flow in the set gutter, the gutter becomes the important water-proof wire in second road, and good waterproofing course is arranged again in the gutter, thereby constitutes the 3rd road water-proof wire.In the gutter, be provided with drainage pipe in addition, can in an organized way be directed in underdrainage system by drainage pipe the water in the gutter effectively, good combination by water guide and waterproof, with cutting off the path of the ponding seepage in deformation joint on flooring or the roofing effectively, play the excellent waterproof purpose.
Than prior art, the present invention has following remarkable advantage: (1) is by the setting in cover plate and gutter, the water that may flow in the deformation joint has carried out organized guiding, change the unordered seepage state of water, thereby efficiently solved the leakage problems that building roofing in the past or flooring deformation joint cause; (2) because the upper surface in the gutter is equipped with waterproofing course, the water that can prevent to flow in the gutter passes through the downward infiltration in gutter self, and anti-sealing flow to next floor along deformation joint; (3) because the place that cover plate and feet bottom thereof contact with the gutter is provided with the separation layer that is positioned at the waterproofing course upper surface, not only the waterproofing course to the bottom plays a protective role, and cover plate and polycrystalline substance layer played buffer action, avoid cover plate that the distortion of deck is caused constraint; (4) adopt the steel concrete cover plate, cost is lower relatively, and good endurance.(5) improved deformation joint and handled, made it to reach not only waterproof but also effect attractive in appearance at the structure at facade place.(6) deformation joint structure design is fused in the structural configuration as an important component part of Overall Structure Design considers, rather than it is handled as leg gusset, the way solution with simple leak stopping has changed traditional design concept.

The specific embodiment
Flooring or roof ponding or rainwater (as at the outside corridor place) are unavoidable, and crucial problem is how water reasonably to be arranged and cut off the infiltration routes of water, and this should be the emphasis on structure is handled.Since the described method construct of background technology exists the path that leaks through the engineering practice proof, water blockoff is difficult to solve waterproof problem so simply.The key of waterproof is to dredge with intercepting to combine, therefore, should accept the ditch of the water that flooring or roofing may leak down, thus water in an organized way be arranged artificially in the setting of deformation joint side, avoid water seepage from seam, take the appropriate anti-scheme of leaking at the two ends of seam simultaneously.
The technical scheme that the embodiment of the invention adopted is as described below, deformation joint 1 top is provided with cover plate 2, the outside portion of deformation joint is provided with gutter 3, the downside outer end of cover plate is provided with the feet 4 that is buckled in the gutter downwards, the upper surface in described gutter is equipped with waterproofing course 5, the place that described cover plate and feet bottom thereof contact with the gutter is equipped with the watertight insulation 6 that is positioned at the waterproofing course upper surface, and the bottom, gutter is provided with the drainage pipe 7 towards underdrainage system.Described cover plate 2 is the steel concrete cover plate, and described waterproofing course 5 is waterproof roll layer or water-repellent paint layer, and described watertight insulation 6 is the waterproof roll layer, and described gutter is made of steel concrete or other material.In addition, can between the slit of cover plate and its side building structure, be embedded with filleting rubber strip 17 with better waterproof.
Because the position is set generally can be divided into following three kinds of situations as shown in Figure 2 of building flooring or deformation joint of roof:
To the junction of choosing 1. distance variableization between situation a, two parallel girders in deformation joint both sides as choosing the corridor outside two;
Distance between situation b, two parallel girders in deformation joint both sides can not change, as the junction when two walls are handled 2.;
Situation c, 3. in flooring or roofing and metope junction.
Therefore at the deformation joint position of above-mentioned various situations, can carry out concrete processing by following different structure respectively to gutter and cover plate respectively:
One, when deformation joint is located between two parallel girders 8 of flooring or roofing (as Fig. 3～Fig. 7 or shown in Figure 8, be that deformation joint is when situation a or two kinds of positions of situation b), at this moment, two outside portions of deformation joint are provided with the gutter 3 that is parallel to beam respectively, and the downside two corresponding outer end portion of cover plate are not provided with the feet 4 that is buckled in two gutters downwards.
(1) situation a: this situation is the distance variableization between two parallel girders in deformation joint both sides, and the beam that promptly is positioned at the deformation joint both sides is position-movable, and this moment, two parallel girder inboards were located in described two gutters respectively, and deformation joint 1 top is provided with cover plate 2.(as shown in Figure 4).
At this moment, the processing of the external end head of deformation joint can be divided into two kinds of situations again: when the external end head of deformation joint is in flooring or roofing 9 and body of wall 10 junctions (as Fig. 3, shown in Figure 5), anti-mouthful 11 that makes progress is hospitalized and be provided with to described cover plate at the junction metope, and be provided with encapsulant 12 between this anti-mouth 11 and metope.Like this,, stop, what influence is waterproof do not had yet because of be provided with anti-mouthful of 11 pairs of corner ponding in the cover plate termination even encapsulant has a small amount of disengaging or aging with anti-mouth or metope.
When the external end head of deformation joint be in flooring or roofing 9 with outside during railing 13 junctions (as Fig. 6, shown in Figure 7), described cover plate is provided with anti-mouthful 11 and downward anti-mouthful 14 that makes progress in the junction, be provided with in upwards anti-mouthful 11 in order to the steel plate 15 of railing welding, the anti-mouthful 14 downward furrow bank outside that is buckled on the gutter, and be embedded with encapsulant 12 between the furrow bank in downward anti-mouth and gutter.Like this, both prevented water from flooring or roofing and outside railing junction or gutter flow to going downstairs, make that again outer facade is succinctly attractive in appearance at deformation joint.
(2) situation b: this situation is two distances between the parallel girder 8 owing to be subjected to the restriction of the layout of body of wall or frame column, can not move, and immobilizes.This moment, two parallel girders outside was located in described two gutters respectively, as shown in Figure 8, during specific design, depth of beam suitably can be strengthened at the beginning of design, so that in the arranged outside gutter of beam.
Two, when between the parallel junction of one-sided beam 8 that deformation joint is located at flooring or roofing 9 and body of wall 10 (as Fig. 9 or shown in Figure 10, promptly deformation joint is when situation c position) has following two kinds to handle structure as the case may be again respectively:
(1) if body of wall does not have beam at corresponding flooring or roofing absolute altitude place, can be according to the removable or immovable situation of the relative body of wall in beam 8 positions, the one-sided beam inboard of flooring or roofing or the outside only are located at (as shown in Figure 9 in gutter 3, the beam inboard is located in the gutter), the following side of described cover plate also is provided with another feet 16 between feet 4 and gutter furrow bank, the side that cover plate is pressed close to metope at deformation joint is provided with anti-mouthful 11 that makes progress, and is being provided with encapsulant 12 between anti-mouth and metope;
(2) if inherent corresponding flooring of body of wall or roofing absolute altitude place are embedded with the beam with the one-sided Liangping row of corresponding flooring or roofing, be respectively equipped with gutter (as shown in figure 10) in the inboard of two curb girders, perhaps, only be provided with gutter (with reference to Fig. 9 or shown in Figure 8) in the one-sided beam inboard or the outside of flooring or roofing according to the removable or immovable concrete condition of the relative body of wall in beam 8 positions.
The waterproofing of movement joints structure of above-mentioned various situations is handled, and handles owing to all carried out effective water-proof drainage with deformation joint in ditch, so can prevent effectively that sealing is penetrated into next floor by ditch or deformation joint.Being provided with all of deformation joint external end head can be handled with reference to the Fig. 3 among the situation a, Fig. 5 according to engineering concrete condition needs.
It should be noted that above these practices require at the very start deformation joint anti-to be leaked and the mutual alignment relation and the processing of thin portion of the structural scheme of aesthetic problem and structural element combine consideration in the working drawing design, rather than as many engineering designs in the past, at the beginning of design, do not consider optimized deformation joint structure node scheme, cause occurring leaking or hindering problems such as attractive in appearance after the engineering use.
