Description
Technical field
The utility model is related to a kind of mixed mud construction installation, especially a kind of large volume heat insulation formwork.
Background technology
In the molding tectonic system of newly-laid concrete, contact concrete simultaneously controls predetermined size, shape, position construction
Part is known as template, supports and the rod piece of fixed form, truss, connecting piece, metal-ware, the suspension bridge etc. that works constitute supporting mass
System；Form work engineering is a kind of temporary structure in concrete construction, but concreting is molded most important；High grade is big
It will produce a large amount of heats of hydration in volume concrete work progress, to reduce mass concrete internal-external temperature difference, avoid thermal cracking
Generation, can routinely use optimised coagulation soil match ratio reduce the heat of hydration and inside concrete installation cooling water pipe carry out it is internal
The method of cooling is controlled into trip temperature.But too fast rate of temperature fall, which can cause temperature difference between inside and outside concrete to become larger, causes temperature to split
Seam, influences concrete quality.Bamboo slab rubber, plank or composite plate are often used in the construction process at present as template, but concrete
Setting time is longer after pouring, and concrete internal temperature changes greatly, and is easily impacted to concrete setting shape, and daytime
Night difference variation can also impact concrete coagulation shape, thus in order to avoid concrete in condensation process due to heat expansion
Change in shape caused by shrinkage can select the material with heat insulation effect as template, but the intensity of conventional heat insulation formwork is not
It is enough, it is difficult to support concrete setting to be molded, when concrete coagulation is also also easy to produce deformation.Therefore, at present in concreting process
In the problem of there are conventional mould heat insulation effect is poor, and concrete coagulation easily deforms, influence construction quality；And heat insulation formwork
Intensity it is relatively low, it is difficult to support concrete, concrete coagulation, which also easily deforms, generates thermal cracking, influences construction quality.
Utility model content
The purpose of the utility model is to provide a kind of large volume heat insulation formworks.The heat insulation effect of the utility model is apparent,
Installation facility, can meet concrete pouring construction requirement, avoid concrete and generate thermal cracking in condensation, improve construction
Quality.
The technical solution of the utility model：A kind of large volume heat insulation formwork, including panel layer, panel layer lower section are equipped with heat preservation
Plate, thermal insulation board include upper clamp plate, lower clamp plate and thermal insulation board, and thermal insulation board is located between upper clamp plate and lower clamp plate.
A kind of large volume heat insulation formwork above-mentioned, it is characterised in that：The thermal insulation board is made of thermal insulation material.
Compared with prior art, the utility model is mainly controlled when avoiding mass concrete from generating thermal cracking
The gradient temperature of concrete, concrete surface heat dissipation is the immediate cause for causing gradient temperature, controls the heat dissipation of concrete topping
Rate, you can the continuity of gradient temperature is controlled, therefore, for this main controlling unit, on template surface and concrete top
Insulating layer is arranged in face, the main means of the rate of heat dispation as control concrete；The purpose of this utility model is that " inside to subtract outer
The temperature control thinking of guarantor " develops " sandwich biscuits " heat insulation formwork, easy to process to be easily installed, and has creeping formwork template at the construction field (site)
Outside carries out the modularization installation of heat insulation formwork, forms thermal insulation layer, reduces concrete surface convection coefficient, slow down concrete surface
Heat loss, heat insulation effect is apparent, in the case where there is larger difference on surface and environment temperature, by temperature difference between inside and outside concrete control
System avoids thermal cracking generation in index request.The thermal insulation board of the utility model is by upper clamp plate, lower clamp plate and heat-insulated board group
At upper clamp plate and lower clamp plate provide a supporting role, there is High-strength compression resistant performance, thermal insulation material thermal insulation board is made and provides thermal insulation separation
Hot property, water resistant, moisture-proof, Corrosion Protection, the utility model is durable cheap, can be according to present various sizes of mould
Plate is processed, installation facility.In conclusion the heat insulation effect of the utility model is apparent, installation facility can meet concrete and pour
Construction requirement is built, concrete is avoided and generates thermal cracking in condensation, improve construction quality.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Label in attached drawing be：1- thermal insulation boards, 2- panel layers, 3- upper clamp plates, 4- lower clamp plates, 5- thermal insulation boards.
Specific implementation mode
The utility model is further described with reference to the accompanying drawings and examples, but is not intended as to the utility model
The foundation of limitation.
Embodiment.A kind of large volume heat insulation formwork, as shown in Figure 1, including panel layer 2,2 lower section of panel layer is equipped with thermal insulation board
1, thermal insulation board 1 includes upper clamp plate 3, lower clamp plate 4 and thermal insulation board 5, and thermal insulation board 5 is located between upper clamp plate 3 and lower clamp plate 4.
The thermal insulation board 5 is made of thermal insulation material.
Operation principle：When concrete pouring construction, first with waling, support beam, support truss, cantilever beam, hang
The conventional constructions equipment such as arm truss, pillar, diagonal brace and tie rod builds support system, and existing template is then inserted into support system
Middle fixation, then the heat insulation formwork of the utility model is installed on the outside of template, last casting concrete waits for concrete coagulation；
During concrete coagulation, the heat insulation formwork of the utility model forms thermal insulation layer, reduces concrete surface convection coefficient, slows down mixed
Solidifying soil surface heat loss exists temperature difference between inside and outside concrete control in the case where there is larger difference on surface and environment temperature
In index request, thermal cracking generation is avoided.
Embodiment 2.Actual effect to verify the utility model does following comparative testing：
The thermal insulation board 1 of 25mm thickness is made of the highly dense plate of 5mm thickness and the extruded sheet of 15mm thickness, utilizes manufactured thermal insulation board
1 makes incubator, using conventional iron sheet template construct iron sheet case；
Contrast experiment tests, and chooses the iron sheet case and incubator of same volume, is separately added into 52 DEG C of warm water, small by 14
Shi Hou, water temperature drops to 29 DEG C of environment temperature in iron sheet case；Water temperature is 44.5 DEG C in incubator；
According to multigroup experimental calculation, when keeping the temperature the temperature inside the box and ambient temperature differences in 10 DEG C, cooling rate is about 1 ~ 2
DEG C/day；
1 material heat insulation effect of above-mentioned the results show thermal insulation board is notable, and rate of temperature fall is slower than iron sheet template.
