Description
Technical field
The present invention relates to a kind of architectural construction technology, be meant a kind of leakage preventing construction technique for inclined roofing especially.
Background technology
Tiltedly roofing is a kind of characteristic embodiment of south of the River culture, tiltedly roof building is because its unique style, more and more be subjected to liking of people, increasing along with oblique roof building, people have also had raising to the requirement of its function of use, and how to keep whole roofing leakproof, free from dampness, the problem that the person of being to use is concerned about the most, existing oblique roof building adopts the flexible web waterproofing course more, the anti-leakage of this oblique roof structure is all better in the ordinary course of things, but in the seepage that runs into continuous rainwater weather or snow and all can occur in various degree in long-pending thick day, moist phenomenon, the lighter causes ornament materials variable colors such as coating, weight person causes ornament materials to rot, even the cast-in-situ concrete reinforcing bar is produced corrosion, causes for the use of resident family and has a strong impact on; Tiltedly the seepage situation of roof structure statistics is as shown in table 1 at present:
Table 1, oblique roof structure seepage situation statistical form
Sequence number | Project | Infiltration area (m 2) | Cumulative area (m 2) | Accumulative total percentage (%) |
1 | The plane seepage | 4.3 | 4.3 | 59.7 |
2 | The infiltration of eaves structure | 1.1 | 5.4 | 75 |
3 | Cant beam angle seepage | 0.8 | 6.2 | 86.1 |
4 | The back timber humidity | 0.5 | 6.7 | 93.1 |
5 | The corner infiltration | 0.3 | 7 | 97.2 |
6 | Roofing be full of cracks infiltration | 0.2 | 7.2 | 100 |
Add up to | 7.2 | / | / |
As can be seen from Table 1, tiltedly the roof structure seepage mainly is the plane seepage, and produce the plane main cause of seepage be concrete leak shake, the levelling out-of-flatness, water/binder ratio is excessive or too small, substrate surface leaves pore.
Summary of the invention
The objective of the invention is to by above-mentioned existing issue is analyzed, thereby a kind of leakage preventing construction technique for inclined roofing that can effectively solve oblique roof structure leakage of building problem is provided.
The technical scheme that the present invention is adopted for achieving the above object is that a kind of leakage preventing construction technique for inclined roofing is characterized in that, may further comprise the steps:
1, disturbing concrete basic unit: concrete batching, control concrete water/binder ratio is between 4~5, adopt by different level, spiral concrete watered on oblique roofing, shakeout after the batch turning and carry out layering and vibrate, concrete vibrating mode adopts plug-in type, carries out for flat twice, adopt the vibrating spear internal vibration earlier, the concrete insertion point intersection of vibrating is controlled in 2/3 scope, vibrating spear vibrate finish after, adopt the vacuum dehydration pump that the moisture content of concrete surface is fully drained, to increase concrete density, the suction back adopts dull and stereotyped jarring machine fully to vibrate, and makes original suction pore all closely knit.
2, close up for the first time: flat vibrate finish after, carry out rolling the first time with cylinder, so that the abundant combination of laitance and aggregate is tied troweling with wooden crab to surperficial cement paste then.
3, close up for the second time: after the laitance for the treatment of the basic unit top layer is done, in basic unit, spread the thick wet ash of shop 1~2mm, wet ash adopts yellow ground, cement, the leak stopping king is by 6~10: 4~6: 1~3 weight ratio mixes, wet ash is agglomerating to hold, unclamping is little loosing for best, after treating wet ash and basic unit fully combining, carry out comprehensive inspection, pull out iron wire, upright shelves etc. cause the object that leaks, in the corner, Liang Jiaobuweichu thickeies processing, make roundlet arc once-forming, lay the SBS waterproof roll, carry out rolling the second time with cylinder then, wet ash is combined closely with basic unit, tie troweling with wooden crab again.
Adopt beneficial effect of the present invention to be:
1, at the excessive or too small problem of water/binder ratio, through experiment repeatedly, rationally control best water/binder ratio between 4~5, when concrete stirred, per 15 mixed with the tube timing that collapses and survey the slump 1 time, guarantee that water/binder ratio is controlled between 4~5; According to the characteristics of oblique roof structure, adopt by different level, spiral pouring procedure substitutes original disposal pouring and be shaped, thereby prevented the generation of constuction joint effectively; And by reasonable processing node, the concrete insertion point intersection of vibrating is controlled in 2/3 scope, effectively prevented to leak and shaken;
2, adopt plug-in type, vibrate for flat twice, vibrating head carry out internal vibration catch up with flat after, adopt the suction of vacuum dehydration pump, fully drain concrete surface moisture content, increase concrete density, the comprehensive leveling of vibrating of dull and stereotyped jarring machine is adopted in the suction back, makes original suction pore all closely knit;
3, in the corner, Liang Jiaobuweichu thickeies processing, makes roundlet arc once-forming, lays the SBS waterproof roll, prevents the seepage of easily infiltration part such as corner, Liang Jiao;
4, on concrete base layer, spread shop 1~2mm thick with yellow ground, cement, leak stopping king by 6~10: the wet ash that 4~6: 1~3 weight ratio mixes has strengthened the anti-damage ability in surface of concrete effectively.
Oblique roofing behind employing the present invention has tile waterproof, rigid waterproof layer, three layers of waterproof of flexible waterproof layer, after testing, free from dampness phenomenon on the plane, the infiltration area is from 7.2m
2Reduce to 0.25m
2, improve waterproof effect, and reduced the use of original TYX603 waterproof roll, produced favorable economic benefit.
The invention will be further described below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is a process chart of the present invention.
The specific embodiment
As shown in Figure 1, leakage preventing construction technique for inclined roofing of the present invention may further comprise the steps:
