Abstract
Description
.
The technology to which the invention belongs and the prior art in the field
The present invention relates to a waterproofing method using a functional special mortar
If the building is newly constructed and repaired, it is used as a waterproofing construction method on the roof of an apartment, an underground parking lot, an underground parking lot, and a liquid waterproofing urethane coating waterproofing method for asphalt application method is mainly used
Many buildings are exposed to chemical and physical phenomena due to climate change and external environmental factors, and the existing concrete and mortar floors are cracked due to the lack of surface strength of the structure floor
Currently, the waterproofing method currently used is the mortar which is used in the floor reinforcement work for the waterproofing work after removing and cleaning the foreign body on the existing floor.
This general mortar product has no fluidity and weak adhesive force, and has a defect that it spreads when it is applied thinly, and has a problem that the compressive strength and surface strength are weak and it can not penetrate the existing floor crack part
Currently, urethane coating waterproofing method, which is widely used for waterproofing construction, is important in the first floor pre-treatment and cleaning. However, most of the buildings in the present construction are flooded with concrete and mortar bottom surface. Especially, After 2-3 years after construction, the urethane waterproofing layer has been lifted from the poor bottom part. When the snow is coming from the roof slab of apartment buildings and various buildings, the bottom surface is cracked and cracked, rain water penetrates, Thereby shortening the life of the building structure due to leakage
We improved the construction method of foundation floor construction and converted the used materials into functional products, so that it is possible to use it quickly and easily at various sites and reduce the cost of construction.
.
In order to solve this problem, in order to solve this problem, before applying the urethane coating waterproofing material which is currently in use in the new construction and repair work, the functional special mortar is first applied to the entire floor surface to strengthen the surface of the existing floor, to form the
Functional special mortar is characterized by high strength and high adhesive strength. Prevention of cracking Debris prevention It is possible to adjust the construction according to each site. Waterproofing using functional special mortar composition so that the urethane coating waterproofing material, which is the second waterproofing layer, There is a purpose in providing the method.
As described above, according to the present invention,
1) When waterproofing the apartment buildings and various buildings by using the special functional mortar, it is possible to mix them with the mixer after pouring only the water to the products in the field. The durability is strengthened to give the product functionality. And the first waterproof layer is formed with 4-5mm for the installation. The second waterproof layer urethane coating waterproofing material is 3mm thick, but the functional special mortar is laid 4-5mm on the bottom, so that the urethane coating layer There was nothing wrong with applying 2 mm of ash, and it saved the cost of labor by reducing labor and material cost.
2) Urethane film This special functional mortar under the waterproofing layer of the product is filled with the original floor according to the conditions of the field floor, so that the irregularities and irregularities on the bottom surface of the construction floor are irregular. It has the effect of improving waterproofing quality
3) The effect of the process improvement is that when the water is poured into the functional special mortar only after the completion of the floor cleaning and cleaning work, the foundation reinforcement work of the floor and the formation of the first waterproof layer are completed.
4) The functional special mortar according to the present invention is first laid on the floor of the construction to solve the weakness of the existing floor, which is the weakest point of the secondary coating urethane coating waterproofing material, and weak surface strength. Waterproof layer has a long lifetime and it has the effect of giving convenience to consumers by reducing the material cost and management cost.
1 is a cross-sectional view for illustrating a waterproofing method of the present invention
DESCRIPTION OF THE DRAWINGS FIG.
1. Existing concrete floor and mortar floor
2. Water-soluble adhesive
3. Functional special mortar
4. Adhesive for urethane
5. Urethane intermediates
6. Urethane mid-protection top coating
In order to achieve the above object, the present invention is characterized in that the material used for the functional special mortar is a percentage of the total weight
Portland cement 40-45% by weight Crude steel cement 0.9-1.2% by weight Melamine 1-1.5% by weight Pellets 0.05-0.5% by weight MC 0.1-0.4% by weight Powder resin 2-4% by weight Calcium carbonate 2.5-3% by weight Silica (Sio2) in an amount of 35 to 44% by weight
Cement which is widely used for the above materials is made of ordinary portland cement which can be easily obtained in the market in the country.
Also, it is possible to cause defects due to the presence of soil in the general sand that does not use the ordinary sand, and the silica sand is washed with clean water to remove the soil from the soil, and then the water is completely removed from the dryer
Existing concrete and mortar It has no floating phenomenon even if the special mortar is cast by 4-5mm in order to repair the floor surface and reinforce the surface strength. It increases the compressive strength and uses the floating fire so that it can flow into the gap between the existing cracks. (60-80mesh 0.6-0.25mm) fine particles were used for the silica sand specimens used to penetrate into the smoothness and cracks of the surface after casting.
Powder adhesive was used to improve adhesion and crude steel cement was mixed to make the hardening time faster than general cement
This product is poured only in water at various sites, mixed with mixer, spread on floor of existing concrete and mortar itself, and after curing, surface is smooth and high strength is maintained
In order to accelerate the initial strength and hardening time, it has good watertightness due to high chemical resistance and high degree of powdering by using crude steel cement. It has no problem even when mixed with good general cement and good compatibility with each other. Was used
The amount of water used in this functional special mortar is 21-22% by weight
In order to use special mortar to reinforce the floor and to form the first waterproof layer
1) Clean the floor that you want to install without any impurities and clean it with high pressure cleaner and vacuum cleaner
2) When the cleaning work is finished, apply the water-soluble primer to the bottom of the construction site using the roller
3) After the water-soluble primer is dried, it is put into a functional special mortar with a weight ratio of 21-22%. After mixing for 2 minutes with a mixer, it is cured on the floor and applied with urethane coating waterproofing material of 2mm thickness
The principles and characteristics of the functional special mortar process of the present invention
1. The construction surface is smooth 2. No lift
3. Excellent abrasion resistance. 4. Easy to install.
5. Easy maintenance and good maintenance
6. High strength and good adhesive force do not cause cracking
This product has such features and characteristics that it can be used for a long time even if it is coated on the special mortar with the urethane coating waterproofing material of the second waterproof layer
The currently used urethane coating waterproofing works by applying urethane coating waterproofing material which is a waterproofing layer on the existing concrete and mortar plastering floor, and the waterproofing work is finished. When the existing floor is weak in strength or when there is moisture, the urethane coating waterproofing layer is floating It is becoming a leak.
In the present invention, the functional special mortar used as the first waterproof layer and the bottom stiffener has high strength and excellent adhesive force, and the bottom surface is smooth and the surface is good, thereby preventing the urethane film waterproof layer from being damaged and increasing the durability. Compared to the previous year.
