Abstract
The invention discloses a leakage processing constructing method for a concrete sloping roof. The leakage processing constructing method includes the following constructing steps: (A) conducting a water spraying experiment, (B) conducting base layer processing, (C) making waterproof mortar, (D) making the waterproof mortar according to a weight mix proportion, (E) conducting thin-layer plastering construction, and (F) conducting maintenance. The leakage processing constructing method has the advantages that gaps and tiny cracks in the motor are filled, the leakage resistance is high, bonding force is large, empty drums can be avoided, the crack resistance can be achieved, and water fleeing can be avoided; a coiled material waterproof layer is omitted, the leakage resisting effect is good, convenience is brought to construction, and the construction cost is reduced; damage can not be generated by temperature changes, humidity changes and vibration, the leakage resistance is improved, and the environment is not polluted.
Description
Technical field
The present invention relates to a kind of construction techniques, in particular, relate to a kind of construction method of concrete sloping roof seepage treatment.
Background technology
In concrete sloping roof work progress, there will be roofing concrete Seepage, cause the reason of this phenomenon mainly: 1, cast-in-place oblique roofing is because its thickness is little, the gradient is large, thereby the abundant jolt ramming of the unavailable insertion vibrator of concrete, can only from bottom to top slowly drag and vibrate with plate vibrator, easily occur that local vibration is not in place, leakiness situation.During 2, due to construction, adopt commercial concrete, the slump is larger, and tiltedly roof pitch is steep, and concreting difficulty is large, vibrates unreal, and roofing concrete just there will be seepage.If oblique roofing cover tile, when part watt sew up touch will rely on when tight oblique roofing concrete from waterproof, so carry out concrete structure itself, from waterproof, be roofing antiseep pith; If seepage treatment method is unreasonable, there will be secondary to study for a second time courses one has flunked, when affecting construction speed, increased construction cost, so concrete sloping roof seepage treatment is most important.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, and a kind of simple, easy to operate, quick, construction method of improving the concrete sloping roof seepage treatment of efficiency of construction, reduction of erection time, reduction construction cost is provided.
The construction method of concrete sloping roof seepage treatment of the present invention, comprises the following steps:
A, trickle experiment: find out the oblique roofing concrete of seepage and carry out mark;
B, base treatment: according to the mark of leakage, from surface, leakiness and loosening concrete chisel removal 16-24mm is dark, and clean up, clear up loosening stone and laitance;
C, make waterproofing mortar: waterproofing mortar is by mass percent portland cement: quartz sand: polychloroprene latex=0.8-1.2:1.5-2.5:0.3-0.4, after stirring, formulated after adding the emulsifier of mortar gross weight 4-6% and the water of 20-30% to mix;
D, thin layer plastering construction: to the dark roofing concrete leakage of the 16-24mm chiseling, clean up, without ponding, adopt a minute two-coat work construction, every layer thickness is 8-12mm, after first floor waterproofing mortar seventy percent is dry, then carries out the second layer and plasters;
E, maintenance: watering after having constructed 24 hours, adopt plastic sheeting covering curing seven days, reach hardening state.
Described waterproofing mortar is by mass percent portland cement: quartz sand: polychloroprene latex=1:2:0.35, and after stirring, formulated after adding the emulsifier of mortar gross weight 5% and 25% water to mix.
Described portland cement is No. 425 portland cements.
Described quartz sand is thick quartz sand in being.
Described polychloroprene latex is cationic chloroprene latex.
Described floated coat wants layering alternately smear densification reality and turn up, and during thin layer plastering construction, environment temperature remains on more than 5 ℃.
Described Concrete Leakage place cuts into horn mouth.
The invention has the beneficial effects as follows: hole and micro-cracks in (1) construction method energy of the present invention filling mortar, impermeability and bonding force are strong, can not produce the phenomenons such as hollowing, cracking resistance, channeling water; (2) reduce coil waterproof layer, antiseep is effective, easy construction, reduction construction cost; (3) Yin Wendu, humidity do not change and are vibrated and produce and destroy, and improve leakage resistance, environmentally safe.
