Detailed Description
The following detailed description of embodiments of the utility model refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.
In the present invention, the use of the directional terms such as "upper, lower, left, right" generally means upper, lower, left, right as shown in reference to fig. 1, unless otherwise specified; "inner and outer" refer to the inner and outer relative to the profile of the components themselves. The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
In order to solve the problems that the existing waterproof surface layer of the stadium is complex in construction or poor in weather resistance, easy to damage and needs to be maintained frequently, the waterproof surface layer structure of the stadium stand has the advantages of being simple in construction and high in weather resistance, and is shown in fig. 1 and fig. 2.
A waterproof surface layer structure of a stadium stand is characterized in that a waterproof surface layer is coated on the surface of the stand 1 to waterproof the stand 1, and the waterproof surface layer sequentially comprises a bottom coating 2, a polyurea waterproof layer 3 and a surface coating 4 from inside to outside;
the material of the cover surface layer 4 is a mixture of polyurea and polyurethane, and the polyurea waterproof layer 3 of the cover surface layer 4 are made of the same polyurea material.
The construction method of the waterproof glue waterproof surface layer is changed, the advantage of simple construction of the waterproof glue waterproof surface layer is kept, the weather resistance of the waterproof surface layer is enhanced, and the later maintenance pressure is reduced.
Specifically, the surface layer of the stand 1 is first coated with a base coat 2, and then coated with a polyurea waterproof layer 3 made of polyurea material. Because the polyurea material and the concrete material of the stand 1 have low affinity and are easy to fall off, the base coat 2 is firstly carried out, the base coat 2 layer and the stand 1 are firmly bonded together, and then the polyurea is bonded with the base coat 2. Meanwhile, although the polyurea material has good waterproof effect and high toughness, practice shows that in places such as stadiums and the like which are directly irradiated by sunlight, the polyurea is easily influenced by ultraviolet rays, and the properties are changed, so that cracking is caused. Therefore, the polyurea waterproof layer 3 is provided with a finishing layer 4 on the upper surface, and polyurethane in the finishing layer 4 can absorb ultraviolet rays. Specifically, the overcoat layer 4 is a mixture of polyurea and polyurethane. At first polyurea material and polyurethane material composition go up similarly can be mutually soluble, and finish coat 4's polyurea can let finish coat 4 and 3 bonding of polyurea waterproof layer more firm again simultaneously. The base coat is a common process method, and the base coat can be prepared by using common organic coating.
On the upper surface of the stand 1, since it is necessary for a person to stand, it is also necessary to have a slip prevention measure. Specifically, be exactly the waterproof surface course that is located stand 1 upper surface has skid resistant course 5, skid resistant course 5 sets up between polyurea waterproof layer 3 and finish coat 4, the material of skid resistant course 5 is the mixture of polyurea and grit. The friction of the friction surface is increased by forming a rough surface by the grits.
Preferably, the particles have a diameter of 0.3mm to 0.5 mm. The thickness of the bottom coating 2 of the waterproof surface layer on the upper surface of the stand 1 is 0.25mm +/-10%, the thickness of the polyurea waterproof layer 3 is 1.5mm +/-10%, the thickness of the anti-skid layer 5 is 0.3mm +/-10%, and the thickness of the surface layer 4 is 0.2mm +/-10%. Here, +/-10% of the thickness of the undercoat 2, polyurea waterproof layer 3, anti-slip layer 5 and overcoat 4 is the amount of deviation allowed at the time of construction. Let the thickness of waterproof layer be less than or equal to the diameter purpose of gravel just can let the gravel stand out, form rough surface.
The thickness of the base coat 2 of the waterproof surface layer on the facade of the stand 1 is 0.25mm +/-10%, the thickness of the polyurea waterproof layer 3 is 1.3mm +/-10%, and the thickness of the top coat 4 is 0.2mm +/-10%. Because the facade of the stand 1 does not need people to stand, skid-proof measures are not needed, and the facade drainage is smoother, so the thickness of the polyurea waterproof layer 3 can be thinner.
The polyurea waterproof layer 3 is made of II-type single-component polyurea.
Wherein the mixing mass ratio of the polyurethane and the polyurea of the finishing coat 4 is 1: 1.5-1: 2.
preferably, the stand 1 is a prefabricated component stand 1.
The working mode of the utility model is as follows: take the waterproof surface layer on the top surface of the stand 1 in fig. 1 as an example.
The large surface of the stand 1 is firstly leveled and cleaned, and if the stand 1 made of prefabricated parts is adopted, leveling is not needed.
Then, the base coat 2 is coated on the large surface of the stand 1, the polyurea waterproof layer 3 is coated on the base coat 2, after the polyurea waterproof layer 3 is firmly bonded, the mixture of polyurea and gravel is coated on the polyurea waterproof layer 3 to construct the antiskid layer 5, then the coat 4 is coated on the antiskid layer 5, and the stand-by stand can be obtained after the coat 4 is firmly bonded.
In the construction of the waterproof surface layer of the vertical surface in fig. 2, only the anti-slip layer 5 is removed.
The above-mentioned embodiments are merely illustrative of the preferred embodiments of the present invention, and do not limit the scope of the present invention, and various modifications and improvements of the technical solution of the present invention by those skilled in the art should fall within the protection scope defined by the claims of the present invention without departing from the spirit of the present invention.
