Description

A kind of hollow sheeting

Technical field

The utility model relates to a kind of hollow sheeting for building.

Background technology

More existing buildings adopt metal or brick and tile sandstone or timber or extremely heavy plastic plate more, and not only waste material but also tension, measuring body performance are not fine under very frivolous situation to some light construction things.Chinese patent 94222645.3 " a kind of insulating plastic pipe plate " provides a good heat insulating, the solution preferably that can replace agricultural film, two plastic tabs by the band ribs constitute, ribs adopts perpendicular or parallel structure, and concrete size cooperation is bad must to influence performance and waste raw material but do not provide.Because the unicity of its purposes, the light construction structure that this technical scheme still can not be used for higher-strength gets on.

The utility model content

The utility model is to overcome the weak point that prior art exists, and provides a kind of section structure rational, tension, a kind of hollow sheeting that compressive property is good.

The hollow sheeting that the utility model provides is made of two layers of plastic plate, forms frame construction by floor between two layers of plastic plate.Total thickness is 2～20mm, and plastic plate and floor plate thickness are 0.1～1.2mm.The technical scheme that total thickness and plastic plate, floor thickness of slab cooperatively interact is: during total thickness 1～4mm, plastic plate, floor thickness of slab are got 0.2～0.4mm; Total thickness 4～8mm, plastic plate, floor thickness of slab 0.3～0.8mm; Total thickness 8～12mm, plastic plate, floor thickness of slab 0.6～1.0mm; Total thickness 12～20mm, plastic plate, floor thickness of slab 0.8～1.2mm.

Framework described in the utility model can be square; Rectangle; Trapezoidal; Cashew nut shape or triangle.

The plastic plate external surface, coated with protective film.

The plastic plate material uses Merlon.

The hollow sheeting that the utility model provides has following advantage compared to existing technology, and its section structure is reasonable, and material tension, compressive property are good, makes simple.Make various sheet materials in the thickness cooperation ratio that provides, can play one's part to the full, guaranteeing that fully mechanical property simultaneously, can reduce raw materials consumption, cost is low.Profiled sheeting is easy to process, easily transportation.Can make light-weight building material, can be used as sheet material usefulness, also can be used as the shell material and use applied range.The insulation, the sound insulation materials that can be used as purposes such as roof use.

The specific embodiment

The hollow sheeting that the utility model provides is seen Fig. 1, constitutes main panel by upper and lower two layers of plastic plate 1.Prop up main panel 1 of two layers of plastic plate by floor 2 and form frame construction.Owing to be frame construction, the air in the cavity at middle part has sound insulation and effect of heat insulation, also just has heat-insulating property, so be fit to make light-duty constructional materials.Plastic plate 1 can use the thermosetting plastics and the thermoplastic of any kind of solid in principle, the plastics variety that functional performance is good, and tension, the compressive property of product are good, but price is higher.The utility model uses Merlon to make hollow sheeting as raw material, and this material removes has the transparency, but outside the transmitted light, its tension, compressive property are good, is to make the suitable material of structural member such as printing opacity ceiling.For making full use of material, the total thickness of hollow sheeting selects 2～20mm to get final product, the vertical distance between the promptly upper and lower layer main panel, and it is too thick that further the raising effect is little to its mechanical property, waste material again, cost improves.The too thin excellent mechanical property that then be difficult for to obtain, and, be not easy to guarantee the structural stability that plastic plate 1 and floor 2 are mutual because of the mould of plastics processing difficulties and after extruding, should not select the too thin hollow sheeting structure of gross thickness for use.Investigate through practicality, it is more suitable that its upper and lower layer plastic plate 1 plate thickness and floor 2 thickness are all elected 0.1～1.2mm as, both can guarantee its mechanical property, again processing easily.The thickness that gross thickness and plastic plate, floor thickness of slab cooperatively interact is selected as follows: during total thickness 1～4mm, select plastic plate, floor thickness of slab 0.2～0.4mm for use.During total thickness 4～8mm, select plastic plate, floor thickness of slab 0.3～0.8mm.Total thickness 8～12mm, plastic plate, floor thickness of slab 0.6～1.0mm.Total thickness 12～20mm, plastic plate, floor thickness of slab 0.8～1.2mm.Plastic plate 1 and floor 2 can once be used the plastics machinery extrusion molding when using with a kind of plastic material, whole structure is good, and simple and convenient.If used the transparent plastic kind, then hollow sheeting possesses properties of transparency, and is particularly useful when being used as the greenhouse or offering side window.Because the material property decision, hollow sheeting is cut out especially easily, is spliced, and can be processed into various heterotype profiled sheets, can rivet moldable welding, bonding.This hollow sheeting is because the plastic body light weight except that avoiding the hot environment use, is suitable for various light building materials and uses.

Frame construction described in the utility model can be square 3; Rectangle; Trapezoidal 5; Cashew nut shape 6 or triangle 4.Based on square 3 and rectangle, see Fig. 1 when making the sheet material use, rectangle does not give diagram.Good in needs tension, resistance to compression, stress is concentrated under the situation, as Fig. 2, shown in Figure 4, preferably uses the floor of triangle 4 or trapezoidal 5 structures.As need tension and elasticity structure preferably, can use cashew nut shape 6, see Fig. 3.If be used for thin shell structures or make the light-duty curved-surface structure that has, as be used for situation such as shell top board, preferably use as shown in Figure 4 trapezoidal 5 or cashew nut shape 6 floors, still can have big anti-pressure ability after the big and distortion of its plasticity.After production was finished, the damage when avoiding processing or transporting can be sticked diaphragm 7 on the surface of main panel, and diaphragm 7 can use things such as plastic sheeting or protection sheet.
