Abstract
The utility model relates to a kind of plastic building template, belongs to constructional materials technical field of structures.In the plastic building template of this utility model, in the through hole due to its sandwich layer, be filled with polyurethane foam filler, thereby in the time of variations in temperature, can not produce serious distortion, avoid the situation of template warping and cracking to occur, thereby be more conducive to building operations, effectively guarantee structural safety, simultaneously, polyurethane foam filler can also avoid concrete grouting to enter cavity, constructability, and plastic building template of the present utility model is simple in structure, with low cost, range of application is quite extensive.
Description
Technical field
The utility model relates to constructional materials technical field of structures, and particularly plastic building material structure technical field, specifically refers to a kind of plastic building template.
Background technology
Plastic building template is a kind of the most common constructional materials, because it is light compared to other material weight, cost is low, is therefore widely used in all kinds of building occasions.Existing plastic formwork adopts sandwich layer to add the three layer construction on lower top layer conventionally, and its surface structure can improve intensity and the surface abrasion resistance of template.But this type of plastic formwork exists weight large, cost is high, the inconvenient problem of constructing.
In order to overcome above-mentioned defect, in prior art, also there is the plastic building template of hollow type, both sandwich layer part had the through hole of hollow, can reduce template weight.But because its inside has cavity, therefore template easily distortion under the effect of expanding with heat and contract with cold, causes adverse effect to construction and structural safety, in addition, also exists concrete grouting to enter the problem of cavity.
Utility model content
The purpose of this utility model is to have overcome above-mentioned shortcoming of the prior art, provide one can not produce because expanding with heat and contract with cold distortion, thereby be more conducive to building operations, guarantee structural safety, avoid concrete grouting to enter cavity simultaneously, and simple in structure, with low cost, range of application is plastic building template quite widely.
In order to realize above-mentioned object, plastic building template of the present utility model has following formation:
This plastic building template comprises sandwich layer and is arranged at respectively upper epidermis and the lower top layer of described sandwich layer upper and lower surface.In described sandwich layer, be provided with at least one through hole extending along this sandwich layer length direction, described through hole connects described sandwich layer two ends, and in described through hole, has polyurethane foam filler.
In this plastic building template, in described sandwich layer, be provided with at least three through holes that are parallel to each other.
In this plastic building template, described through hole is uniformly distributed in described sandwich layer, and spacing between each through hole is identical.
In this plastic building template, this plastic building template also comprises edge band, described edge band comprises baffle plate and is fixed on the sealing of hole projection on this baffle plate, quantity and the position of the quantity of described sealing of hole projection and position and described through hole match, described edge band is fixed on the two ends of described sandwich layer, and described sealing of hole projection is pegged graft and is fixed on described through hole port.
Adopt the plastic building template of this utility model, in through hole due to its sandwich layer, be filled with polyurethane foam filler, thereby in the time of variations in temperature, can not produce serious distortion, avoid the situation of template warping and cracking to occur, thereby be more conducive to building operations, effectively guarantee structural safety, simultaneously, polyurethane foam filler can also avoid concrete grouting to enter cavity, constructability, and plastic building template of the present utility model is simple in structure, with low cost, range of application is quite extensive.
Brief description of the drawings
Fig. 1 is the structural representation that plastic building template of the present utility model and edge band split.
Fig. 2 is the plastic building template of the present utility model cross sectional representation of (not comprising edge band).
Fig. 3 is the structural representation of plastic building template of the present utility model and edge band assembling.
Detailed description of the invention
In order more clearly to understand technology contents of the present utility model, describe in detail especially exemplified by following examples.
Referring to shown in Fig. 1, is the structural representation of plastic building template of the present utility model.
In one embodiment, as shown in Figure 1, 2, 3, this plastic building template comprises sandwich layer 3 and is arranged at respectively upper epidermis 1 and the lower top layer 2 of described sandwich layer 3 upper and lower surfaces.In described sandwich layer 3, be provided with at least one through hole 4 extending along this sandwich layer length direction, described through hole connects described sandwich layer 3 two ends, and has polyurethane foam filler 6 in described through hole 4.
In embodiment more preferably, in described sandwich layer 3, be provided with at least three through holes that are parallel to each other 4.And each through hole 4 is uniformly distributed in described sandwich layer 3, and spacing between each through hole 4 is identical.
In preferred embodiment, this plastic building template also comprises edge band 5, described edge band 5 comprises baffle plate 51 and is fixed on the sealing of hole projection 52 on this baffle plate 51, and quantity and the position of the quantity of described sealing of hole projection 52 and position and described through hole 4 match.When described edge band 5 is fixed on the two ends of described sandwich layer 3, described sealing of hole projection 52 is pegged graft and is fixed on the port of described through hole 4, can more effectively avoid concrete to enter in sandwich layer 3.
In actual applications, plastic building template of the present utility model not only has advantages of conventional plastic template lightweight, inexpensive.Meanwhile, can effectively avoid the warping and cracking due to variations in temperature generation, reduce construction cost, ensure, in the situation of timber intensity, to be more conducive to construction.
Adopt the plastic building template of this utility model, in through hole due to its sandwich layer, be filled with polyurethane foam filler, thereby in the time of variations in temperature, can not produce serious distortion, avoid the situation of template warping and cracking to occur, thereby be more conducive to building operations, effectively guarantee structural safety, simultaneously, polyurethane foam filler can also avoid concrete grouting to enter cavity, constructability, and plastic building template of the present utility model is simple in structure, with low cost, range of application is quite extensive.
In this manual, the utility model is described with reference to its specific embodiment.But, still can make various amendments and conversion obviously and not deviate from spirit and scope of the present utility model.Therefore, manual and accompanying drawing are regarded in an illustrative, rather than a restrictive.
