Multifunctional concrete maintenance template
Technical field
The utility model relates to the technical field of concrete blinding, particularly relates to a kind of template that is used for concrete pouring construction.
Background technology
The early stage heat and moisture preserving maintenance of concrete is to guarantee that concrete strength increases, prevents that concrete from producing the important measures of temperature contraction fissure, and the major reason that concrete produces the temperature contraction fissure causes owing to the early stage heat and moisture preserving maintenance of concrete is not enough.Since early stage moisture-keeping maintaining time of concrete is short still cause solid concrete intensity do not reach designing requirement, cover to reinforcement concrete density poor, be subject to the major reason that extraneous corrosion factor such as carbon dioxide and chlorion corrodes.
Existing template commonly used; Like steel form, plank sheathing, glued board etc., its plate body is processed by homogenous material, and heat-insulating property is relatively poor; Make insulation moisture-keeping maintaining material and hang plastic film and other material at template outer surface or concrete surface before the form removal or after the form removal at the construction field (site); Because of can only being hung on template or concrete outer surface, be subject to the influence of extraneous factor such as wind, the heat and moisture preserving effect is relatively poor; Cause the early stage internal-external temperature differences of concrete members such as Dun Qiang, bridge bigger thus, concrete is prone to the temperature contraction fissure.In the process of construction of some large bridges, the surface of concrete structure requirement of strength is very high, needs accurate grasp when need water, when does not need water, and existing surface maintenance work all to be manual work carry out, construction quality can not guarantee.
Summary of the invention
In order to overcome deficiency of the prior art, the purpose of the utility model is that a kind of insulation, moistening effect multifunctional concrete maintenance preferably template is provided.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: a kind of multifunctional concrete maintenance template, comprise substrate and heat-insulation layer, and substrate is located at outermost layer; Heat-insulation layer is located at the substrate inboard; The surface of said heat-insulation layer is provided with fish tail and waterproof layer, and the inboard of said fish tail and waterproof layer is provided with the hydroscopic high-molecular resin layer, and the inboard of being close to the hydroscopic high-molecular resin layer is provided with sheet plastic; On said thin plate, have permeable hole, be connected through screw between said substrate, heat-insulation layer, fish tail and waterproof layer, hydroscopic high-molecular resin layer and the sheet plastic.
Aforesaid multifunctional concrete maintenance template is characterized in that: described heat-insulation layer comprises that perlite, PU cotton, asbestos or glass are cotton.
Compared with prior art, the advantage of the utility model is:
1. because the utility model is provided with heat-insulation layer; Make template not only have the moulding function; Also have good heat-insulating property, can reduce hydration heat of concrete greatly and be dispersed into the rate of heat transfer of external environment condition, concrete surface temperature and internal temperature are more or less the same through template; Thereby reduce thermal (temperature difference) stress greatly, prevented that effectively concrete from producing temperature difference crack.Insulation layer surface is protected by watertight composition, can prevent that moisture from infiltrating heat-insulation layer, guarantees that the heat insulation effect of the utility model is good.
2. hydroscopic high-molecular resin is because of having the advantages that water absorption is big, water holding capacity is strong; The template of the utility model is after concreting; Redundant moisture penetrates into the hydroscopic high-molecular resin layer through permeable hole, and moisture also can carry out reverse supply through permeable hole, in the concrete curing process; Hydroscopic high-molecular resin both can guarantee few water, can guarantee not lack of water again.

The specific embodiment
For further disclosing the technical scheme of the utility model; Now be described with reference to the accompanying drawings the embodiment of the utility model: as shown in Figure 1; A kind of multifunctional concrete maintenance template comprises substrate 1 and heat-insulation layer 2, and substrate 1 is located at outermost layer; Heat-insulation layer 2 is located at the inboard of substrate 1, and heat-insulation layer 2 comprises that perlite, PU cotton, asbestos or glass are cotton.The surface of heat-insulation layer 2 is provided with fish tail and waterproof layer 4, can prevent that moisture from infiltrating heat-insulation layer.The inboard of fish tail and waterproof layer 4 is provided with hydroscopic high-molecular resin layer 3, and water absorption is big, water holding capacity is strong.The inboard of being close to hydroscopic high-molecular resin layer 3 is provided with sheet plastic 6, on thin plate 6, has permeable hole 7, and redundant moisture can penetrate into hydroscopic high-molecular resin layer 3 through permeable hole 7.Be connected through screw 5 between substrate 1, heat-insulation layer 2, fish tail and waterproof layer 4, hydroscopic high-molecular resin layer 3 and the sheet plastic 6.
More than, the basic design and the basic principle of the utility model have been set forth through introduction to listed embodiment.But the utility model never is limited to above-mentioned listed embodiment, and every equivalent variations, improvement of doing based on the technical scheme of the utility model reaches and deliberately become of inferior quality behavior, all should belong to the protection domain of the utility model.
