Abstract
The utility model relates to a butt plate with a sandwich structure. The utility model is composed of an upper surface layer, a lower surface layer and an inner sandwich layer, wherein, the upper surface layer as an antiaging, wearproof and skidproof layer is made of antiaging, wearproof and skidproof materials having the function of decoration, the sandwich layer is generally made of polyester concrete, asphalt concrete or light wood, and the lower surface layer is composed of high-strength fabrics and high-performance resin. The utility model having the characteristics of theft protection, high bearing capacity and low cost can be applied to the well covers on inspection wells, mud flowing wells, drainage ditches and tree pits.
Description
Technical field
The utility model belongs to the well lid that is applied on manhole, Liu Nijing, gutter, the plant pit.
Background technology
Be used for the well lid on manhole, Liu Nijing, gutter, the plant pit now, normally cylinder iron or cement make, casting iron well lid is because recyclable utilization, often stolen, cause many accidents, and cement well lid is generally reinforced concrete structure, and supporting capacity and casting iron well lid have big gap, and the scope of application is limited.
Summary of the invention
The purpose of this utility model is at the above problem, and a kind of antitheft, supporting capacity is strong, cost is low sandwich cover plate is provided.
The purpose of this utility model is achieved in that the utility model is made of upper surface layer, undersurface layer and inner interlayer.
Technique effect of the present utility model is: because the utility model adopts the structure of interlayer, so different layers can adopt the material of different characteristics, thereby be combined into cover plate antitheft, that supporting capacity is strong, cost is low.
The utility model is described in further detail below in conjunction with drawings and Examples.
Description of drawings
Fig. 1 is the front view of the utility model embodiment one.
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is the sectional view of embodiment two.
The specific embodiment
As depicted in figs. 1 and 2, the cover plate integral body of embodiment one is circular, constitute by upper surface layer 1, undersurface layer 3 and inner interlayer 2, upper surface layer 1 is mixed by silica, calcium carbonate, alumina particle, unsaturated-resin and glass fabric, interlayer 2 is the polyester concrete that mixed by sandstone and unsaturated-resin, undersurface layer 3 is to be made of glass fabric and high performance resin, adopts resin bonding between three layers, and being shaped as of cover plate bottom is as shown in Figure 2 trapezoidal.
Embodiment two and embodiment one different place only is that the shape of cover plate bottom is different, and being shaped as of embodiment two cover plates bottom is parabola shaped, as shown in Figure 3.
Upper surface layer is ageing-resistant, wear-resisting, skid resistant course in the utility model, adopt material ageing-resistant, wear-resisting, anti-skidding and that have a decoration function to make, and decorative pattern and color can design, wear-resistant material is mainly high-quality silica, corundum etc., intergranular cementing agent is mainly high performance resin, also can add the high-intensity fiber fabric in case of necessity; The material of interlayer generally adopts polyester concrete, bituminous concrete or light wood; Undersurface layer is made of high-intensity fiber fabric and high performance resin.And above-mentioned high performance resin can adopt epoxy resin, phenolic resins, unsaturated polyester resin.
The manufacturing of the utility model cover plate can adopt mold pressing, resin transfer moulding, hand to stick with paste technologies such as technological forming.The shape of cover plate also can be square except the circle of top embodiment.Cover plate on the cover board has through hole from top to bottom as required as the time spent on gutter, Liu Nijing, the plant pit, and through hole can be circular hole, also can be square hole.
