Abstract
The utility model relates to an easily-demoulded concrete formwork which is characterized in that a layer of glass fiber cloth is paved on one surface of the prior wooden formwork close to the concrete; an electric heater is arranged on the glass fiber cloth; a layer of iron sheet with the same size as the required formwork is wrapped outside the electric heater; and a layer of paint is coated on the iron sheet. The paint melts quickly at high temperature, a gap appears between the concrete and the formwork, so that the concrete disconnects from the formwork naturally. When in use, the the formwork can be stripped off from the concrete component conveniently without knocking the formwork to damage the formwork.
Description
Technical field:
The utility model belongs to the building implement field, is specifically related to a kind of conveniently stripped concrete blinding.
Background technology:
In building trade, people are a large amount of disposable templates of using timber to make in the process of precast concrete, cause great waste.Some building unit has been brought into use standardized unit template, connects into the template of different shape with the unit template, thereby has saved a large amount of timber.But the existing unit template lacks effective mould emptier; after the concrete setting; need template be stripped down from concrete component by tapping template, the unit template inevitably deforms like this, and this has more aggravated the not adhesive problem of template faying face.
Summary of the invention:
The purpose of this utility model is the defective at prior art, and the template of the concrete demoulding of a kind of convenience from solidifying is provided.Template is improved greatly in the utilization rate of the realm of building construction, cut the waste, reduce construction cost.
The technical solution of the utility model is as follows: will have plank sheathing now and lay layer of glass cloth by concrete one side, on glass fabric, adorn an electric heater, one deck appearance and size iron sheet the same with required template wrapped in the outside of electric heater, on iron sheet, be coated with a coating then, melted rapidly when this coating runs into high temperature.When needing the demoulding after the concrete setting of cast, with the energising of the electric heater in the template, the iron sheet temperature on the template heats up rapidly, and the coating on the iron sheet is melted rapidly, just occurs the slit between concrete and the template, and concrete and template also just are separated from naturally.
Owing to adopt such scheme, can template be destroyed without tapping template, template is stripped down from concrete component easily.
Description of drawings
Accompanying drawing is the longitudinal profile structural representation of the utility model embodiment.
Among the figure: 1 coating, 2 iron sheets, 3 quartz sands, 4 pearl rock sands, 5 electric heaters, 6 planks, 7 glass fabrics.
The specific embodiment:
The utility model is dispersed on the iron sheet for the heat that makes electric heater uniformly, between the space of electric heater and iron sheet, be filled with quartz sand and pearl rock sand, because quartz sand and pearl rock sand have good heat radiating, the heat on the electric heater evenly can be dispersed on the iron sheet rapidly.
The utility model is described in detail in detail with reference to the accompanying drawings
With reference to accompanying drawing, on existing plank sheathing, lay layer of glass cloth 7 by concrete one side, on glass fabric 7, adorn an electric heater 5, one deck appearance and size iron sheet 2 the same with required template wrapped in the outside of electric heater 5, lean on concrete one side at iron sheet 2, be coated with last layer coating 1,, can suitably revise and can easily wrap with assurance iron sheet 2 if the size of plank 6 is improper.
Because glass fabric 7 can play good heat-resisting heat-blocking action, the heat energy of electric heater 5 can not be discharged on the plank 6, for the heat that makes electric heater 5 is dispersed on the iron sheet 2 uniformly, between the space of electric heater 5 and iron sheet 2, be filled with quartz sand 3 and pearl rock sand 4, because quartz sand 3 and pearl rock sand 4 have good thermal diffusivity, the heat on the electric heater 5 evenly can be dispersed on the iron sheet 2 rapidly.Quartz sand 3 and pearl rock sand 4 required ratios are that quartz sand 3 accounts for 90%, pearl rock sand 4 accounts for 10%.
The template that adopts the utility model to make is convenient in demoulding, and concrete appearance is smooth, and template can also be used repeatedly, and can save a large amount of timber, reduces construction cost, improves construction quality.
