Abstract
The utility model relates to a GFRTP (glass fiber reinforced thermoplastic) compound structure building plastic formwork. A directional continuous fiber reinforced thermoplastic material is adopted to make a planar baseplate, and a multilayer structure with different fiber distribution directions is adopted, so that the objectives of high mechanical performance, small deformation, thin type, light weight and high strength are achieved; LFT (long fiber reinforced thermoplastic) is adopted to make back reinforcing ribs of the formwork, so that strength, especially flexural strength and rigidity, of the formwork is further improved. The compound structure building plastic formwork formed by combining a faceplate with the back reinforcing ribs is light in mass, high in strength and low in price.
Description
Technical field
The utility model relates to field of compound material, specifically discloses a kind of GFRTP duplex building plastic formwork.
Background technology
Building Trade in China development is very rapid, its annual amount of wood that consumes accounts for the annual total quantity consumed 30% of national timber, and construction timber shutterings is the main template of Building Trade in China so far, but its circulation makes number of times few, life-span is low, cause a large amount of timber resources wastes, and China is the country of timber resources relative shortage, thereby it is very important, also very urgent to carry out non-Wood construction formwork research and development.Plastic formwork has many advantages, developed countries is constantly developed and is applied, as German double-decker plastic formwork, U.S.'s decorative plastic template, Japan's hollow-core construction plastic formwork, Korea S GMT template ... China also starts to explore the nineties, in succession develop some products, as radwood template, PVC foaming formwork etc., but than external product, domestic non-wooden template exists intensity low, rigidity deficiency, swollen swell absorbs water, distortion is large, the low deficiency that waits of turnover access times, although price is low compared with imported product, but because of the life-span short, poor performance, do not obtain large-scale production and application.
Utility model content
Goal of the invention of the present utility model is: provide a kind of strong mechanical performance for overcoming the above problems, be out of shape little, slim, lightweight, high-strength, and low price, the duplex GFRTP building plastic formwork that the life-span is long.
The utility model adopt technical scheme be such:
A kind of GFRTP duplex building plastic formwork, it comprises the planar substrates being made up of some layers of directed continuous glass fibre reinforced thermoplastic plastics material and forms back side reinforcing rib by strong mechanical performance LFT.
Further, every layer of continuous glass fibre of described planar substrates is evenly distributed, and direction is consistent, and each layer of continuous glass fibre is designed to the each angular distribution of 0～90 degree.
Further, described each layer of continuous glass fibre is designed to 0 ° or 25 ° or 45 ° or 75 ° or 90 ° of angular distribution.
Further, described planar substrates and back side reinforcing rib are same thermoplastic matrix material.
In sum, adopt such scheme the beneficial effects of the utility model to be:
Be aided with the template reinforcing rib of making of LFT at substrate back, further improve template flexural strength and rigidity.Because LFT mechanical property is higher than SFT, so this duplex building plastic formwork mechanical property is good, to be out of shape littlely, heat resistance is good, recycles often, and also high-strength light, transport, easy for installation, price is lower, has larger market application and development potentiality.
Brief description of the drawings
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is the utility model structural representation;
Fig. 2 is a kind of manufacture method flow chart of the present utility model;
Fig. 3 is another kind of manufacture method flow chart of the present utility model.
Detailed description of the invention
Disclosed arbitrary feature in this manual (comprising any accessory claim, summary and accompanying drawing), unless narration especially all can be replaced by other equivalences or the alternative features with similar object.Unless narration especially, each feature is an example in a series of equivalences or similar characteristics.
As shown in Figure 1, a kind of GFRTP duplex building plastic formwork, it comprises planar substrates 1 and back side reinforcing rib 2, described planar substrates 1 is made up of 3～10 layers of directed continuous glass fibre reinforced thermoplastic plastics material, every layer of continuous glass fibre is evenly distributed, direction is consistent, and each layer of continuous glass fibre is designed to the each angular distribution of 0～90 degree, and preferred angle is 0 ° or 25 ° or 45 ° or 75 ° or 90 °; Described back side reinforcing rib 2 is made up of strong mechanical performance LFT, and reinforcing rib 2 shapes, size etc. are according to the design of construction formwork performance requirement, and it can further improve template mechanical property, and (especially rigidity), and improve dimensional stability; Described planar substrates 1 and back side reinforcing rib 2 are same thermoplastic matrix material.
Embodiment 1:(as shown in Figure 1)
1. continuous glass fibre → thermoplastic molten body stain stain → unidirectional continuous glass fibre reinforced thermoplastic plastics thin slice;
Unidirectional continuous glass fibre reinforced thermoplastic plastics thin slice by direction stacked → template substrate;
3.LFT puts into template mould reinforcing rib groove, above placing mold base board heating, pressurization → building plastic formwork.
Embodiment 2:(as shown in Figure 2)
1, continuous glass fibre heat of immersion thermoplastic plastic molten mass → unidirectional continuous glass fibre reinforced thermoplastic plastics thin slice;
2, unidirectional continuous glass fibre reinforced thermoplastic plastics thin slice is undertaken stacked by design;
3, continuous glass fibre → plastics → continuous glass fibre reinforced thermoplastic plastics material strip;
4, material strip is cut and is cut by dimensional requirement;
5, material strip is put into mould reinforcing rib groove (can add part LFT-D) and put into substrate layer lamination → heating pressurization → building plastic formwork above.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any amendments of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
