Description
Technical field
The utility model relates to the insulation layer device of auxilliary rib apparatus, the especially concrete dam of concrete dam.
Background technology
Build concrete dam at severe cold area, during particularly relatively thin concrete dam, often need carry out permanent thermal insulation on the dam body surface.As the permanent thermal insulation bed device, at present, what use in the prior art is the warming plate of pasting on the dam facing of concrete dam, and for example Xiangshui County's arch dam is once at dam facing paste polystyrene plastic foamboard, and the sub-arch dam of Fenhe River Er Ba and crossdrift is once at dam facing polyurethane spray foam layer.At short notice, this class insulation layer can be fitted closely with dam facing because of it, and heat insulation effect is good, but the time one is long, produces cracking phenomena between insulation layer meeting and the dam facing, even wearing out owing to the insulation layer material, appearance comes off and makes dam facing expose out, makes the insulation layer device lose its due effect.After the partial failure of insulation layer device, when it is repaired,, very difficult because aerial work than higher, be implemented in the dam.Life-span Chang Keda of concrete dam 100 years.How to make insulation layer device on it can be muchly fit well, do not make dam be subjected to the influence that temperature in four seasons changes and failure phenomenon such as ftracture is the problem that should solve in the development of concrete dam attemperator now with the dam surface.
Summary of the invention
The purpose of this utility model is to improve deficiency of the prior art, solves the problem that dam surface heat preservation bed device separates or comes off with dam body in long-term the use, and a kind of and the dam body surface adeciduate concrete dam permanent thermal insulation bed device that do not ftracture is provided.
The purpose of this utility model is achieved in that
The concrete dam permanent thermal insulation bed device that the utility model provides comprises warming plate and the fixed structure piece of being made by thermal insulation material, and this fixed structure piece and described warming plate combine.
Make the rigidity of material of described fixed structure piece and intensity all greater than the material of making described warming plate, and the bond strength of itself and warming plate is greater than the bond strength of warming plate and concrete dam facing.In use, the part of described fixed structure piece is embedded in the dam body of concrete dam, makes it and the dam body strong bonded, thus, just can make also firm having combined of described warming plate and dam body.
Described fixed structure piece can be the rib that is fixedly arranged on the described warming plate inside bottom surface.This rib its underpart in use is embedded in concrete dam body.In order to guarantee that warming plate combines more firmly with dam facing, described fixed structure piece preferably also comprises the ribbed plate that the side with described warming plate connects firmly, its upper/lower terminal stretches out on the described warming plate one section of bottom surface, in use the lower end of described ribbed plate also is to be embedded in the concrete of dam body, by described rib, bottom surface to warming plate retrains, and the lower end of rib sets firmly in the dam body, and warming plate is securely fixed on the dam facing.Dam facing generally is the inclined plane, and be fixedly arranged on the described warming plate side and the effect that one section described ribbed plate has a side direction to block to warming plate is stretched out in the upper end, can retrain the downglide motion trend of warming plate effectively, thereby further warming plate reinforced on dam facing.The lower end of described ribbed plate also can connect firmly with described rib or become one structure, and like this, can make this insulation layer device convenient and reliable building in the process with the chimeric construction of dam body of concrete dam.
Described fixed structure piece can also be to be located at the backplate in the described warming plate outside, is provided with securing member between this backplate and the described warming plate and backplate and warming plate is connected firmly be integral, and described securing member stretches out one section in order to combine with dam body in the inside bottom surface of warming plate.In use, the described section of stretching out of described securing member plugs in the concrete that is fixed on dam body, thus described warming plate and backplate are connected firmly on dam facing, and the backplate outside being located at covers warming plate, can prevent wearing out, ftracture and coming off of warming plate effectively.Described backplate just can be an armored concrete slab; Described securing member can be the stainless steel screw rod.
The concrete dam permanent thermal insulation bed device that the utility model provides can form firm embedded syndeton with dam body by the fixed structure piece of the ad hoc structure that connects firmly with warming plate, thereby make warming plate be installed on the dam facing securely, do not ftracture, do not come off, high insulating effect, long service life.
