Abstract
The utility model discloses a kind of bamboo wood-plastic composite building formwork, it is characterized in that, it is that three kinds of materials have levels and combine, and described template comprises inner formword and is coated on the plastic film layers (1) of inner formword outer surface; Described inner formword is overlapping by longitudinal bamboo curtain splint layer (2) and horizontal wood chip layer (3) and is formed, or centered by bamboo curtain splint layer layer, in the upper and lower surface of central core, the lumber layer be made up of timber is set; The rubberised layer for being hot bonding is equipped with outside described bamboo curtain splint and wood chip.The utility model intensity is high, can Reusability number of times high, production cost is low.
Description
Technical field
The utility model relates to composite plate, specifically a kind of bamboo wood-plastic composite building formwork.
Background technology
Current China building template develops into now, of a great variety, mainly based on wooden model, bamboo mould, mold.In use, often kind of template embodies self advantage, has also occurred the defect of self simultaneously.Wooden model cost is low, intensity difference, and access times are low; Bamboo mould intensity is high, and cost is high, and Reusability number of times is also low; Mold access times are high, and cost is high, not heatproof, yielding.
Utility model content
The weak point that the utility model exists in order to avoid existing template, provides the bamboo wood-plastic composite building formwork that a kind of intensity is high, durable in use, production cost is low.
The utility model technical solution problem adopts following technical scheme:
A kind of bamboo wood-plastic composite building formwork, its design feature is, described template comprises inner formword and is coated on the plastic film layers of inner formword outer surface; Described inner formword is overlapping by longitudinal bamboo curtain splint and horizontal wood chip and is formed, or centered by bamboo curtain splint layer, in the upper and lower surface of central core, the lumber layer be made up of timber is set; Described bamboo chip and wood chip outer surface are equipped with the rubberised layer for being hot bonding.
The utility model design feature is also:
The bamboo curtain splint of described bamboo curtain splint layer is woven by some bamboo plate rope yarns of condition of equivalent thickness and forms, and some spiles that the wood chip of described wood chip layer is peeled into required condition of equivalent thickness by trees are spliced.
Described plastic sheeting layer thickness is 0.5-2mm.
Compared with the prior art, the utility model beneficial effect is embodied in:
The utility model intensity is high, can high, the feature such as production cost is low of Reusability number of times.
The utility model is provided with plastic layer due to the outer surface of inner formword, and plastics have the performance do not bonded with concrete, and smoothness, hardness are all higher than bamboo timber, so it is not afraid of the grazing of reinforcing bar sandstone, and the easily demoulding, not injured surface.
The utility model inner formword adopts bamboo wood compound, and the hardness of mao bamboon is high, elasticity large, good toughness, heatproof are indeformable, improves the intensity of template.
The utility model inner formword is timber between plastics and bamboo wood, and it is low and with the degree of adhesion of plastics higher than the performance of bamboo wood, make product not delamination that timber has cost.
Accompanying drawing explanation
Fig. 1 is embodiment 1 composite shuttering structural representation.
Fig. 2 is embodiment 2 composite shuttering structural representation.
Number in the figure: 1 thin layer, 2 bamboo curtain splint layers, 3 lumber layers.
By detailed description of the invention, explanation is further explained to technical solutions of the utility model below in conjunction with accompanying drawing.
Detailed description of the invention
Embodiment 1
As shown in Figure 1, bamboo wood plastics composite template, template comprises inner formword and is coated on the plastic film layers 1 of inner formword outer surface; Inner formword is overlapping by longitudinal bamboo curtain splint layer 2 and horizontal wood chip layer 3 and is formed, or centered by bamboo curtain splint layer, arranges in the upper and lower surface of bamboo curtain splint layer the lumber layer be made up of timber; Bamboo chip and wood chip outer surface are equipped with the rubberised layer for being hot bonding.
Bamboo curtain splint in embodiment is compiled by some little bamboo chip ropes and is formed, and wood chip is formed by trees rotary-cut; The splicing seams of the adjacent bamboo chip layer 2 of inner formword, wood chip layer 3 is vertical interlaced (namely bamboo curtain splint layer is that longitudinal direction, wood chip layer are for horizontal).
Concrete production stage is:
1, after bamboo curtain splint or bamboo chip, wood chip being dried, then impregnation or gluing dry.
2, required plastic sheeting (thickness 0.5-2mm) is extruded with extruding machine.
3, embryo is organized:
1. ground floor is placed on smooth on plate of mating formation spreading out plastic sheeting.
2. the second layer is layered on the wood chip throwing glue above plastic sheeting.
3. the bamboo curtain splint of dipped glue or bamboo chip, one or more layers overlaps paving on the second layer (thickness of every layer of bamboo curtain splint or bamboo chip is between 1-5mm) to third layer.
4. the 4th layer is layered on glue-coated wood chip above third layer.
5. plastic sheeting is layered on above the 4th layer, namely organizes embryo and all complete.
6. the material that group embryo completes, hot press is sent to, heating, pressurization, cooling forming.Then take out sheet material, saw limit, edge sealing, be packaged into finished product.
Embodiment 2
As shown in Figure 2, bamboo wood plastics composite template, template comprises inner formword and is coated on the plastic film layers 1 of inner formword outer surface; Inner formword is for adopting by bamboo curtain splint layer 2 and the crisscross base material that overlaps to form of wood chip layer 3, and namely one deck wood chip, one deck bamboo chip overlap lay some layers.Bamboo curtain splint in base material is spliced by some little bamboo chips, and wood chip is spliced by some spiles; The bamboo chip of base material adjacent layer and the splicing seams vertical interlaced of wood chip.
Concrete production stage is
1, after bamboo curtain splint or bamboo chip, wood chip being dried, then impregnation or gluing dry.
2, mat formation: having soaked the bamboo curtain splint of glue or bamboo chip, wood chip needed for product thickness, the crisscross overlap of different levels is layered on together, then puts hot press into, heats, pressurizes, is cooled to base material.
3, with laminating machine, base material positive and negative is sticked plastic cover.
Table 1 is the elastic modelling quantity correction data of the utility model embodiment composite shuttering and existing building template.
