Abstract

The utility model relates to a plastic building template, which is mainly used in construction bearing for planes, beams, columns and the like of various buildings. The plastic building template is made by compounding a polypropylene surface layer (1), a modified polypropylene intermediate layer (2) and a polypropylene bottom layer (3) which are arranged in sequence from the top to the bottom. The utility model has the advantages of good humidity resistance, a large number of turnover times, smooth and clean surface, strong corrosion resistance, strong acid resistance and alkali resistance, light weight, convenient processing and no requirements for coating of the release agent in the process of application.

Description

Plastic building template

Technical field

The utility model relates to a kind of construction formwork.Be mainly used in the construction supporting of the plane of all kinds of buildings or beam column etc.Belong to building material technical field.

Background technology

Before the utility model was made, traditional construction formwork mainly contained three kinds of wooden form, Bamboo Formwork and steel forms.They have the following disadvantages respectively:

Wooden form and Bamboo Formwork moisture resistance are poor, a little less than the corrosion resistance, use down and in the wet environment inappositely; The wooden form and the Bamboo Formwork number of turnover are few, normal access times 3～4 times; Wooden form and Bamboo Formwork air spots are sliding, not bright and clean, need the secondary plastering engineering, and template and concrete fissility are bad, are difficult for the demoulding.

A little less than the acidproof and alkali resistance of steel form, Heavy Weight, a form removal are not light, constructing operation and the carrying security reliability is relatively poor, labour intensity is high, and efficiency of construction is low, and processing is inconvenient; Need the brushing release agent in the steel form use, be not easy cleaning and maintenance.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, provide that a kind of moisture resistance is good, the number of turnover is many, surface smoothing, bright and clean, corrosion resistance is strong, acidproof and alkali resistance is strong, need not the plastic building template of brushing release agent in light weight, easy to process, the use.

The purpose of this utility model is achieved in that a kind of plastic building template, has polypropylene top layer, modified polypropene middle level and polypropylene bottom to be composited for three layers from top to bottom successively.

The utility model plastic building module has following advantage:

1, plastic formwork moisture resistance, corrosion resistance are strong, and be acidproof and alkali resistance is strong, be particularly suitable for underground and wet environment in use.

2, plastic formwork intensity height, toughness is strong, shock-resistant, elasticity is strong, be difficult for to produce distortion, thereby increase substantially the number of turnover of template.

3, plastic formwork is in light weight, form removal is light, constructing operation and carry safe and reliable, labour intensity is low, the efficiency of construction height.

4, plastic formwork can be sawed, can dig, can follow closely, process very convenient, this product can with various material plate such as present wood (ring) veneer simultaneously and use.

5, after tested, the normal access times of plastic formwork can reach about 30 times, can reduce construction cost greatly, and the waste and old template after using is also recoverable, old for new service, and it is more considerable to save cost, the development of favourable template leasing industry.

6, plastic formwork closes in the use and need not the brushing release agent, cleans easily and maintains.Therefore the template cleaning, the upkeep cost that reduce.

7, plastic formwork surface smoothing, bright and clean saves the secondary plastering engineering.Template and concrete fissility are good, the easily demoulding, and accelerating construction progress shortens the construction period greatly, helps to realize clear-water concrete.

8, plastic formwork can absolutely reclaim, regenerate in case of damaging, and reduces the pollution of discarded object to environment.

In a word, plastic formwork has the use general character and the more characteristics that are better than conventional template of routine building template.Therefore, plastic formwork will become building operations with mould Dai Mu, to mould Dai Zhu and to mould the renewal product of Dai Gang.

Description of drawings

Fig. 1 is the section structure schematic diagram of the utility model plastic building template.

Among the figure: polypropylene top layer 1, modified polypropene middle level 2, polypropylene bottom 3.

The specific embodiment

Referring to Fig. 1, the utility model plastic building template, have successively from top to bottom polypropylene top layer 1, modified polypropene middle level 2 and polypropylene bottom 3 totally three layers compoundly be extruded into moulding and form.

Claims

1. plastic building template, it is characterized in that described template have successively from top to bottom polypropylene top layer (1), modified polypropene middle level (2) and polypropylene bottom (3) totally three layers be composited.
