Abstract

The utility model discloses a novel wood-plastic composite building framework, which relates to building formworks in the field of building technology.The novel wood-plastic composite building framework 1 is tabular, which adopts a composite construction equipped with a core layer 3 and a surface layer 2.The core layer is formed by the mixing of thermoplastic plastic, wood powder, rubber powder and inserts.The surface layer is composed of engineering plastics and inserts.A bonding layer 4 is arranged between the surface layer and the core layer.The thickness of the framework is 8 - 20 mm and the width thereof is 1000 - 1500 mm.The novel wood-plastic composite building framework has the advantages of light weight, convenient usage, high hardness and strength, long service life and low price and production cost, which is reusable and is made of waste plastics, waste rubber and wood chip leftovers, thereby turning waste into treasure. The framework can be sawed or nailed and the surface thereof is impact-resistant. Concrete members formed by using the framework are good in quality. Meanwhile, the weight of the framework is only a half of the weight of a steel framework.

Description

A kind of novel wood-plastic complex architectural template

Technical field:

The utility model relates to technical field of buildings, relates generally to construction formwork.

Background technology:

In building engineering construction, the cast-in-situ concrete member will use template in a large number as floor, column, crossbeam, body of wall etc., before this, mainly adopt steel template and wooden template and a small amount of plastic formwork, the shortcoming of steel template is that weight is big, easy-to-rust is difficult for the demoulding, the price height; The shortcoming of wooden template is that intensity is low, and the non-watertight component surface quality that influences is easy to go rotten, and consumes timber resources; The shortcoming of the plastic formwork that adopts then is low, the yielding fragmentation of intensity at present.

Summary of the invention:

Goal of the invention of the present utility model, be with mould Dai Mu, to mould Dai Gang, design new prescription and structure of transvers plate, make full use of waste or used plastics, rubber and wood chip leftover bits and pieces the like waste, a kind of novel wood-plastic complex architectural template is provided, to substitute steel template and wooden template, overcome the defective of existing plastic formwork.

This novel wood-plastic complex architectural template 1 tabular has sandwich layer 3 and top layer 2 lamination layer structures, and sandwich layer is made of thermoplastic, wood powder, rubber powder, inserts mixing; The top layer is made of engineering plastics, inserts; Has tack coat 4 between top layer and the sandwich layer.The thermoplastic of described sandwich layer is polyvinyl chloride or polypropylene or polyethylene, and inserts is a Paris white, and described wood powder granularity is 30---150 orders, rubber powder granularity are 30---150 orders; The engineering plastics on described top layer are ABS or Merlon or polyamide, and inserts is a Paris white; Described tack coat is an epoxy adhesive.Template thickness is 8---20mm, the width of plate are 1000---and 1500mm.

Another technical scheme of this novel wood-plastic complex architectural template is that the template tabular is made of thermoplastic, wood powder, rubber powder, inserts mixing.

The good effect of this novel wood-plastic complex architectural template is that light weight only is 1/2nd of a steel template weight, can saw and can follow closely, and is easy to use; Hardness is good, the intensity height, and the surface is shock-resistant, and it is long to reuse the life-span, does not absorb water, and it is good to cast quality of concrete members; Utilize making such as waste or used plastics, waste old and wood chip leftover bits and pieces, turn waste into wealth, low price can reduce production costs.

The accompanying drawing invention:

Accompanying drawing 1 the utility model front view

Accompanying drawing 2 the utility model vertical views

A kind of embodiment partial enlarged drawing of accompanying drawing 3 the utility model I

The another kind of embodiment partial enlarged drawing of accompanying drawing 4 the utility model I '

Concrete aforesaid way:

1,2,3 given a kind of concrete aforesaid ways in conjunction with the accompanying drawings are described further the structure of the utility model.A kind of novel wood-plastic complex architectural template 1, the master looks tabular, overlooks and is rectangle, and has sandwich layer 3 and top layer 2 lamination layer structures, has tack coat 4 between top layer and the sandwich layer.Sandwich layer 3 is made of thermoplastic, wood powder, rubber powder, inserts mixing, and described thermoplastic is waste polyvinyl chloride or polypropylene or polyethylene, and present embodiment adopts waste polyvinyl chloride.Inserts is a Paris white.The wood powder granularity is 30---150 orders, rubber powder granularity are 30---150 orders, present embodiment adopts wood powder 30 orders, rubber powder 100 orders.Top layer 2 is made of engineering plastics, inserts, and described engineering plastics are ABS or Merlon or polyamide, and present embodiment adopts ABS.Described tack coat 4 is an epoxy adhesive.Template thickness is 8---20mm, the width of plate are 1000---and 1500mm, length is 2200---2500mm.In the present embodiment, the thick 10mm of template, wide 1200mm, long 2400mm.

Manufacture craft is to adopt earlier extrusion equipment respectively, and extrusion molding is made middle layer plate and sheet surface layer, adopts epoxy adhesive that sheet surface layer is bonded in the middle layer plate surface then.Can be in the sandwich layer upper and lower surface top layer that bonds respectively, also can be only in upper surface (casting concrete face) bonding top layer.No matter be sandwich layer or top layer, also add a little auxiliary, be mainly stabilizing agent, sliding agent and coupling agent at blending process.

Accompanying drawing 4 is the another kind of embodiment partial enlarged drawing of the utility model I ', is mixed by thermoplastic, wood powder, rubber powder, inserts to constitute the expressing technique moulding, wherein, thermoplastic is polyvinyl chloride or polypropylene or polyethylene, and present embodiment is a polyvinyl chloride, and inserts is a Paris white, the wood powder granularity is 30 orders, the rubber powder granularity is 100 orders, the thick 10mm of template, wide 1200mm, long 2400mm is a kind of novel hard PVC composite shuttering.In the engineering construction, can intercept corresponding size as required and use.

Claims

1. a novel wood-plastic complex architectural template is characterized in that tabular; Template thickness is 8---20mm, wide by 1000---1500mm, long 2200---2500mm.
