As shown in fig. 1, the embodiment provides a water seepage prevention construction method for a garage roof, which includes the following steps:
s1, carrying out measurement and line laying on the garage top plate according to the position size of the first-layer balcony or the overhanging model;
s2, arranging a constructional column at the first-layer balcony or the overhanging-shaped external corner, and planting ribs according to the line placing position;
s3, building the garage from the top plate of the garage to the first-layer balcony or the overhanging modeling position to form a building wall;
s4, compacting and trowelling the masonry wall and the constructional column through cement mortar, and leveling the masonry wall and the constructional column with the first-layer balcony or the overhanging model;
s5, adopting 1:3 cement mortar to carry out the treatment of plastering the splayed corners at the internal corners of the masonry wall and the garage top plate;
s6, processing the internal corner by adopting a waterproof material to form an additional layer at the internal corner;
s7, sticking the coiled material of the garage top plate to a preset height from the internal corner upwards, and carrying out edge sealing treatment;
and S8, firmly adhering the outer heat insulation board, and performing backfilling construction.
The garage large-surface waterproof construction method can adopt 2mm non-cured rubber asphalt waterproof coating and 4mm planted roof chemical root-resistant waterproof coiled material for construction. The constructional column is characterized in that in order to enhance the integrity and stability of a building, a reinforced concrete constructional column is arranged in a wall body of a multi-layer brick-concrete structure building and is connected with each layer of ring beam to form a space frame capable of resisting bending and shearing, and the constructional column is an effective measure for preventing a house from collapsing. The arrangement positions of the constructional columns are at four corners of the outer wall, the joints of the cross walls and the outer longitudinal walls at staggered layers, two sides of a larger hole, the joints of the inner wall and the outer wall of a large room, and the like. In addition, the number of layers of the house is different, the earthquake intensity is different, and the setting requirements of the constructional columns are different.
To facilitate masonry of the wall, optionally, in step S3, a masonry process is performed using the sintered shale brick of MU15 and the cement mortar of M10. The dimensions of the sintered shale bricks of MU15 are typically 240mm by 115mm by 53 mm. The M10 cement mortar is a cement mortar with the compressive strength of 10 MPa, and consists of cement, sand and water according to the proportion of 1: 5.27: 1.13 according to the proportion. After blending and forming, pressure testing is needed, and M10 cement mortar can be obtained after the strength of the cement mortar reaches 10 MPa. If the pressure test is not qualified, the pressure test cannot be used, otherwise, the quality of the building is influenced.
To facilitate subsequent level construction, optionally, in step S3, the facade of the masonry wall is inwardly retracted by 1cm compared to the first balcony or overhanging form.
Optionally, in step S3, when the masonry height is greater than or equal to 2m, a ring beam is arranged around the middle of the masonry wall for reinforcement. The ring beam is used for matching with a floor slab and a constructional column, so that the overall rigidity and stability of the house are improved, the damage of the uneven settlement of the foundation to the house is reduced, and the influence of earthquake force is resisted. In order to prevent the adverse effects of uneven settlement of a foundation or large vibration load on a house, a ring beam is generally provided with a reinforced concrete ring beam or a reinforced brick ring beam in a wall body so as to enhance the overall rigidity of a masonry structure house.
Optionally, in step S3, the surface layers of the masonry wall, the constructional columns and the ring beams are compacted and leveled by 1:3 cement mortar, and the thickness is 1 cm. 1:3 cement mortar is adopted for compacting and smoothing, and the main steps are as follows: base layer processing → elevation finding, elastic thread → water sprinkling and wetting → plastering cake and marking rib → stirring mortar → cement slurry combining layer → cement mortar paving surface layer → wood trowel smoothing → iron trowel pressing for the first time → second pressing → third pressing → maintenance.
The specific steps of the base layer treatment can be as follows: firstly, sweeping off dust on a base layer, brushing and removing a ash residue layer of ash slurry skin by using a steel wire brush and a chisel, brushing off oil stain on the base layer by using 10% of caustic soda water solution, and flushing the reducing solution in time by using clean water. The specific steps of finding the height snapping line can be as follows: according to the +50cm horizontal line on the wall, measuring the surface elevation downwards and bouncing on the wall. The specific steps of watering and moistening can be as follows: and uniformly sprinkling water on the ground base layer once by using a sprinkling can. The concrete steps of plastering cakes and marking ribs (or called as punching ribs) can be as follows: determining the plastering thickness of the surface layer (not less than 20mm) according to the horizontal line of the surface layer elevation of the wall bomb around the room, pulling the horizontal line to begin plastering cakes (5cm multiplied by 5cm), wherein the horizontal-vertical distance is 1.5-2.00 m, and the upper plane of each cake is the ground surface layer elevation. If the room is large, in order to ensure the flatness of the whole surface layer, a mark rib (or called a punching rib) is needed to be smeared, cement mortar is paved between the mortar cakes, the width of the cement mortar is the same as that of the mortar cakes, and the cement mortar is folded and smeared to be consistent with the upper surface of the mortar cakes by using a wooden trowel. The mixing proportion of the mortar materials for paving the mortar cake and the marking ribs is the same as that of the mortar for plastering the ground.
The concrete steps of stirring the mortar can be as follows: the stirring of the mortar adopts a mode of directly adding water into dry mixed mortar dry powder on site for stirring, and the weight ratio of the dry mixed mortar to the water is preferably 1: 0.15-0.2 (dry powder: water), and the consistency is not more than 50 mm. The water addition amount should be strictly controlled during stirring, so that the stirring is uniform and the color is consistent. The concrete steps of brushing the cement slurry bonding layer can be as follows: before cement mortar is laid; and (3) coating a layer of cement paste with a water-cement ratio of 0.4-0.5 (cleaning the residual ash of the plastering cake before coating, and then spraying water to moisten the residual ash), wherein the coating area is not too large, and the mortar of the pavement layer is coated along with the coating. The concrete steps of paving the cement mortar surface course can be as follows: after the cement slurry is coated, the cement slurry is paved next to the cement slurry, the cement slurry is uniformly paved among the ash cakes (or among the standard ribs), and then the mortar is scraped by a wooden scraping bar according to the height of the ash cakes (or the standard ribs). When the mortar is spread, if the ash cake (or the mark ribs) is hardened, the used ash cake (or the mark ribs) is knocked off and filled with the mortar after the wood scraping bar is scraped. The wooden trowel rubbing-flat method comprises the following specific steps: after the wood scraping bar is scraped, the wood is immediately rubbed by a wood trowel, the operation is carried out from inside to outside, and the flatness of the wood trowel is checked by a 2m guiding rule at any time.
The specific steps of the first pressing pass of the iron trowel can be as follows: after the wooden trowel is trowelled, the wooden trowel is immediately pressed for the first time by using an iron trowel until the mortar is discharged, if the surface of the mortar is thin and has a bleeding phenomenon, a mixed material of dry cement and sand (1: 1) can be uniformly scattered once (the sand needs to pass through a 3mm sieve), then the wooden trowel is used for forcefully trowelling and pressing, so that the dry mixed material and the mortar are tightly combined into a whole, and the iron trowel is used for flattening after water absorption. If the ground has the requirement of dividing, dividing lines are bounced on the surface layer, a slit is opened by a slit scraper, and the slit is pressed to be flat, straight and smooth by the scraper. The above operations are all completed before the initial setting of cement mortar. The specific steps of the second calendering can be as follows: after the surface mortar is initially set, a person steps on the surface mortar, when the surface mortar has foot prints but does not sink, the surface mortar is pressed for the second time by using an iron trowel, the concave part of the pit is filled while the surface mortar is troweled and pressed, and the surface is flattened and calendered without pressure leakage. After the ground with the lattices is pressed, the chute is used for sliding and pressing, so that the straight edge of the seam, the clear seam and the smooth and straight inside of the seam are realized. The specific steps of the third calendering can be as follows: and performing third press polishing (people step on the iron trowel to remove a little foot print) before the final setting of the cement mortar, and when no more lines are formed on the iron trowel, flattening, compacting and press polishing (which must be completed before the final setting) of all the lines left in the second press polishing by using the iron trowel. The concrete steps of curing can be as follows: and 24h after the ground is finished by calendaring, spreading sawdust or covering other materials, spraying water and maintaining, keeping moist, and enabling people to get on the floor when the compressive strength reaches 5MPa for not less than 7 d.
To ensure that the ring beam has sufficient structural strength, optionally, in step S3, the cross-sectional dimension of the ring beam is consistent with the cross-sectional dimension of the construction column.
To ensure that the construction post has sufficient structural strength, the construction post may optionally have a cross-sectional width that corresponds to the beam width of the first balcony or overhanging figure in step S2.
Alternatively, in step S2, if the cantilever beam is not formed, the cross-sectional dimension of the structural column is set to 150mm by 150mm, so that the method is suitable for construction work in various scenes.
To improve the waterproof effect, optionally, in step S6, the length of the two sides of the internal corner of the additional layer at the internal corner is 250mm, and the thickness is 2 mm.
Optionally, in step S6, the non-curing rubber asphalt waterproof paint is applied to the internal corner to complete the first layer structure of the additional layer at the internal corner, the non-woven fabric is used as the second layer structure of the additional layer at the internal corner, and the first layer structure of the additional layer at the internal corner is pressed against the non-curing rubber asphalt waterproof paint, and then the non-curing rubber asphalt waterproof paint is applied to the first layer structure of the additional layer at the internal corner.
The non-solidified rubber asphalt waterproof paint is prepared by using rubber, asphalt and softening oil as main components and adding temperature controller and stuffing and mixing. The non-cured rubber asphalt waterproof coating can seal base cracks and capillary holes and can adapt to complex construction operation surfaces; the non-cured rubber asphalt waterproof coating is not cured for a long time after contacting with air, always keeps the characteristics of sticky colloid, has strong self-healing capability, is sticky when being touched and difficult to peel, and still has good bonding performance at the temperature of minus 20 ℃. The non-cured rubber asphalt waterproof coating can solve the problems of cracking, flexural fatigue or advanced aging in a high stress state of a waterproof layer and the like caused by the fact that the cracking stress of a base layer is transferred to the waterproof layer; meanwhile, the viscosity of the creep material of the non-cured rubber asphalt waterproof coating can well seal capillary holes and cracks of a base layer, so that the problem of water channeling of a waterproof layer is solved, and the waterproof reliability is greatly improved; the non-curing rubber asphalt waterproof coating can also solve the problem of compatibility when the existing waterproof coiled material and the waterproof coating are used in a compounding way.
The non-woven fabric, also called non-woven fabric, is a new generation of environment-friendly material, and has the characteristics of water repellency, air permeability, flexibility, no combustion supporting, no toxicity, no irritation, rich colors and the like. If the non-woven fabric is placed outdoors for natural decomposition, the longest service life of the non-woven fabric is only 90 days, the non-woven fabric is placed indoors for decomposition within 5 years, and the non-woven fabric is nontoxic and tasteless and has no any remaining substances during combustion, so that the non-woven fabric does not pollute the environment and is suitable for washing. It directly uses high polymer slice, short fiber or filament to form a novel fiber product with soft, air-permeable and plane structure through various fiber web forming methods and consolidation techniques. The non-woven fabric bag has the environmental protection performance which is not possessed by plastic products, and the time of the non-woven fabric bag being naturally degraded is far shorter than that of a plastic bag, so that the non-woven fabric bag made of non-woven fabrics is also known as the most economical and practical environmental-protection shopping bag.
