Abstract
The utility model discloses a compound heat-preserving beam bottom mother plate which has a three-layer compound plate structure, wherein a bottom layer is a bearing layer, a middle layer is a heat-preserving layer, a surface layer is a thin steel plate layer, the surface layer and the middle layer are fixed on the bottom layer through a connecting piece, and the heat-preserving layer is preferably overlaid by at least one sackcloth layer and at least one plastic film layer. The compound heat-preserving beam bottom mother plate can not only be used as a bottom mother plate of a reinforced concrete structure beam, but also play a heat-preserving role, and prevents the internal temperature of a newly cast reinforced concrete structure beam from fast dissipating from beam bottom to generate the cracking of the beam, thereby ensuring the quality of the beam; the utility model does not need to cover heat-preserving materials to preserve the heat of the beam bottom; and in addition, the utility model has simple structure, easy construction and good heat-preserving effect.
Description
Technical field
The utility model relates to a kind of building operations template, is specifically related to a kind of complex heat-preservation beam bottom board plate that is applicable to that conversion crossbeam etc. has insulation to require.
Background technology
When adopting the seamless technology job practices of monolithic to change the crossbeam pouring construction, part super-section beam belongs to concrete in mass.In the pouring construction process, it is to prevent that the concrete in mass temperature from descending rapidly and form the important measures of shrinkage crack that concrete is carried out effective temperature control.For the temperature control of concrete in mass, generally be to adopt the method that is incubated at the concrete surface covering insulation material.During the construction of conversion crossbeam casting of concrete in mass, its temperature can be scattered and disappeared by its top, below and side, so the top of crossbeam, below and side all will take to cover heat insulating material such as burlap bag and be incubated.Because the top and the side ratio of conversion crossbeam concrete in mass are easier to covering insulation material, so the heat insulation effect ideal; Then because of being subjected to the influence of level and vertical support system, the coverage effect of heat insulating material is undesirable in the below of crossbeam, thereby does not reach good heat insulation effect.
The utility model content
The purpose of this utility model is the weak point at existing reinforced concrete structure crossbeam bottom heat preservation technology, provide a kind of simple in structure, satisfy the complex heat-preservation beam bottom board plate that the insulation of reinforced concrete structure crossbeam bottom requires.
For achieving the above object, the utility model adopts following technical scheme: complex heat-preservation beam bottom board plate is the three-layer composite board structure, wherein bottom is a supporting layer, the intermediate layer is an insulation layer, and surface layer is the steel sheet layer, and surface layer and intermediate layer are fixed on the bottom by connector.
Further, above-mentioned insulation layer is by one deck sackcloth at least with one deck plastic film layers is folded at least forms.
Above-mentioned supporting layer preferably adopts veneer or plank.
Above-mentioned connector is a plurality of fixed nail, and staple hammers into and penetrate surface layer and the intermediate layer is ended to entering supporting layer from surface layer.
The utility model is by adopting said structure, both can be used as the soffit formwork of reinforced concrete structured beam, can play the effect of insulation again, prevent that the reinforced concrete structured beam internal temperature of newly building scatters and disappears at the bottom of the beam rapidly and causes the crossbeam cracking, has guaranteed the crossbeam quality; Need not again to carrying out the covering insulation material insulation at the bottom of the beam; And simple in structure, it is simple and easy to construct, high insulating effect.
Description of drawings
Fig. 1 is a plan structure schematic diagram of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to the sectional structure schematic diagram.
Among the figure:
The 1-supporting layer; The 2-insulation layer; The 21-sackcloth; The 22-plastic sheeting; 3-steel sheet layer; The 4-connector.
Now the utility model is described in further detail in conjunction with the accompanying drawings and embodiments:
The specific embodiment
As depicted in figs. 1 and 2, complex heat-preservation beam bottom board plate described in the utility model is the three-layer composite board structure, and wherein bottom is a supporting layer 1, and the intermediate layer is an insulation layer 2, and surface layer is a steel sheet layer 3, and surface layer and intermediate layer are fixed on the bottom by connector 4.
Supporting layer 1 plays the support effect, and enough strength and stiffness be arranged, and generally gets the veneer of 18 millimeters thick or the plank of about 20 millimeters thick and is processed into, and present embodiment adopts plank as supporting layer.
Insulation layer 2 by one deck sackcloth 21 at least and at least layer of plastic film 22 be laminated, burlap bag and plastic sheeting mainly play insulation effect, the number of plies and the thickness laid are relevant with the hydration heat of concrete adiabatic temperature, can calculate according to heat exchange principle and determine, lay layer of plastic film 22 between the two-layer burlap bag 21 of present embodiment system employing and form insulation layer 2.
Surface layer adopts steel sheet layer 3, and the protection insulation layer also makes template surface smooth.
What the connector 4 of present embodiment adopted is the plurality of fixed nail, and each staple hammers into and penetrate surface layer and the intermediate layer is ended to entering supporting layer from surface layer.
The manufacturing process of the complex heat-preservation beam bottom board plate of present embodiment is as follows: according to the width (width of bottom plank and deck-siding are together) of beam, sanction is cut to have spliced supporting layer 1 (plank) and laid and is fixed on the horizontal stupefied wood of beam position support system earlier; On supporting layer 1, lay one deck sackcloth 21 earlier, and then lay layer of plastic film 22, re-lay one deck sackcloth 21 at last, form insulation layer 2; On 2 of insulation layers, lay steel sheet layer 3; Use connector 4 (staple) that steel sheet layer 3 and insulation layer 2 nails is solid on supporting layer 1 (plank) at last.
