Abstract
The utility model relates to a simple waterproof grandstand for stadiums, comprising a concrete step shaped base body, a cement mortar layer, a copolymer mortar layer, a modified resin paint layer and a polyurea elastomer provided on the surface of the base body. After the compositing processing of each layer, the grandstand has great waterproof function, the polyurea elastomer layer on the surface is dense, smooth and glossy, great in flexility and wearing resistance, high in tensile strength and waterproof performance, and adapted to be directly sitting on. Consequently, chairs are not needed to be added, the grandstand is simple in structure, low in cost, due to adoption of coating and spraying modes for material of each layer, the construction is simple, the time limit of the project is short, engineering investment and construction cost are saved.
Description
Technical field
The utility model relates to the grandstand in type stadium, particularly a kind of simple and easy waterproof grandstand.
Background technology
At present, the stadium grandstand comprises the seat that is provided with on stepped ramp type matrix that concrete makes up and the matrix, the vertical plane of each step of concrete stepped ramp type matrix is wiped with cement mortar, the horizontal plane of step adds reinforced mesh and pea gravel concreten layer successively, its surface scribbles epoxy wear-resistant coat or terrace lacquer, to prevent the grandstand seepage lower floor's accommodation at the stadium that is located at below the grandstand is caused damage.
This grandstand, will be through following a plurality of construction sequences: sidewall cement mortar maintenance → grandstand mark time the surface layer reinforced mesh colligation → surface layer pea gravel concreten construction of leveling blanket of marking time → grandstand pea gravel concreten maintenance → deformation joint cleaning, beat glue joint filling → grandstand epoxy wear-resistant coat or terrace coats with lacquer the seat of constructing → install and fix, platform construction process operation is more, construction period is longer relatively, construction investment and construction cost are bigger, under the not high situation of grandstand utilization rate, form the relative waste of construction fund.And epoxy wear-resistant coat or terrace lacquer is easy to generate crackle even crack because of the various stress effects of substrate concrete, influences impression.
Summary of the invention
The purpose of this utility model provide a kind of cheap, construction is fast just, the simple and easy waterproof grandstand of stepped ramp type durable in use, safety and environmental protection, it need not to add seat, surface layer can be directly as the seat and have the good function of waterproof.
This simple and easy waterproof grandstand comprises concrete stepped ramp type matrix, and the surface of matrix has cement sand bed again, composition polymer screed, modified resin enamelled coating and polyurea elastomer layer successively on the cement sand bed.
Said each step plane has the 2% flashing gradient from inside to outside.
Said polyurea elastomer layer thickness is 〉=2mm.
In the utility model grandstand, concrete stepped ramp type matrix is by after the layers of material Combined Processing, has the excellent waterproof function, particularly surperficial polyurea elastomer laminar surface closely knit, smooth smooth, that color and luster is consistent, the lines flow smoothly is soft, impression quality good, has good pliability, abrasion resistance and tensile strength, can prevent effectively that surface layer hollowing, dusting, crack from producing, its water resistance is superior, and be suitable for directly sitting using, therefore need not with adding seat, simple in structure, cost reduces, and is convenient to cleaning.In the layers of material, cement sand bed, polymer mortar layer and modified resin enamelled coating all adopt the coated mode, and the polyurea elastomer waterproofing course on surface adopts spraying method, and job practices is simple, flexible, quick, but reduction of erection time, raising work efficiency have been saved construction investment and construction cost.Grandstand regular maintenance, recondition expense are extremely low.Have economy, environmental protection, energy-conservation, safety, good endurance, hygienic cleaning characteristics easily, economic and social benefit is good.
Description of drawings
Fig. 1 is the cross-sectional view of simple and easy waterproof grandstand.
Among the figure, 1-concrete substrate, 2-cement sand bed, 3-polymer mortar layer, 4-modified resin enamelled coating 5-polyurea elastomer layer.
The specific embodiment
With reference to accompanying drawing, this grandstand comprises concrete stepped ramp type matrix 1, and the surface of matrix 1 has cement sand bed 2 again, composition polymer screed 3, modified resin enamelled coating 4 and polyurea elastomer layer 5 successively on the cement sand bed 2.
In the accompanying drawing: 1, concrete substrate is carried out removing surface; 2, smear cement mortar, floating, and keep the 2% low inside and high outside flashing gradient, secondary press polish, fully maintenance; 3, criticize and scrape the early strengthened polymer mortar, surface finish is carried out in surfacing after the curing, and the uneven place of remaining depression epoxy available clay is repaired and batch scraped; 4, treat abundant drying after, smear JSD-1 modified resin lacquer with the mode of roller coat or brushing by acetone modulation, present paint finishes to estimating the surface; 5, after the modified resin enamelled coating drying, Spray Polyurea Elastomer solidified 24 hours after the spraying for the first time at twice, carried out the spraying second time again.
Claims (3)
1. simple and easy waterproof grandstand comprises concrete stepped ramp type matrix, and the surface of matrix has cement sand bed again, it is characterized in that on the cement sand bed composition polymer screed, modified resin enamelled coating and polyurea elastomer layer successively.
2. simple and easy waterproof grandstand according to claim 1 is characterized in that said each step plane has the 2% flashing gradient from inside to outside.
