Abstract
The utility model discloses a low-foaming multi-layer plastic building molding board, which is used for casting concrete in building construction. The molding board is formed by a core layer and surface layers covered on two lateral surfaces of the core layer, and the molding board is in flat board shape, groove shape or right angle shape. The surface layers and the core layer all utilize alkenes thermoplastics as base materials, but the component and the content of the surface layers and the core layer are different, the thickness of the surface layers is 0.4-1.2 mm, and the thickness of the core layer is 10-18 mm. The surface layers of the molding board are wear resistant and fire-retardant, and are fine in toughness, the core layer is light in weight and fine in rigidity, the molding board is combined in rigidity and toughness integrally, thereby increasing the integrated property. The utility model is easy in mold stripping and clearing, is favorable for reusing the molding board and recycling after scraping, is especially convenient in casting concrete at corners of beams and columns, and can increase the construction efficiency.
Description
Technical field
The utility model relates to a kind of construction formwork that is used for pouring concrete construction, particularly low foamed multi-layer plastic building template.
Background technology
In the engineering construction processes such as building, bridge, tunnel, the essential a large amount of template of concrete pouring.Various templates are also constantly updating, and mainly contain wooden form, steel form, bamboo offset plate etc.What application was more at present is wooden plywood, in light weight, easy to use, but is limited to the second-rate of sheet material and cementing agent, uses and has just scrapped for 3～5 times, waste resource, recovery difficulty.Also there are many deficiencies in the plastic formwork of building trade appearance recently, the hardness height, the poor toughness that have, and easy embrittlement, bad processing, the rigidity that has is not enough, and is yielding.Chinese patent 99111262.8 discloses a kind of glass fiber reinforced low foaming plastic architectural template, it is a base-material by thermoplastic, add glass fiber, blowing agent and other filler, through extruder hot melt extrusion molding, improved formwork rigidity, access times are many, reduced cost, have made marked progress, but still following shortcoming is arranged: 1, this template be the individual layer flat board from outside to inside by making with the compound of a kind of component and content, can not take into account the rigidity and the toughness of template simultaneously, its combination property is not good enough; 2, this template is a hollow structure, and concrete easily pierces in the cavity during use, is difficult to remove, and brings difficulty to reclaiming; 3, in corner's when construction that is used for members such as beam, post, use inconvenient.What 4, this mould material produced when the construction cutting is pure last, splashes human body and scratches where it itches unbearable, unhealthful.
The utility model content
The purpose of this utility model is to overcome weak point of the prior art, provide a kind of good combination property, easily demoulding, easily reclaim, can improve efficiency of construction, reduce construction cost, be of value to the low foamed multi-layer plastic building template of health.
The technical solution of the utility model is: low foamed multi-layer plastic building template is made of sandwich layer and the top layer that is covered in the sandwich layer two sides, and template is plate, grooved or perpendicular type.
Thick 0.4～the 1.2mm in described top layer, the thick 10～18mm of sandwich layer.
Low foamed multi-layer plastic building template of the present utility model is made of sandwich layer and top layer, and the component and the content on sandwich layer and top layer are different, thickness is also different, after deliberation and test, has determined scientific matching, the top layer is smooth, wear-resisting, fire-retardant, good toughness, sandwich layer is in light weight, and good rigidly is sawed, construction processing such as nail easily, template realizes strong and unyielding combination, has improved combination property.This template is the entity plate, and middle do not have a cavity, and concrete can be stained with into inside during use, the easily demoulding, easy to clean, long service life help the repeated use of template and scrap after reclaiming, help reducing construction cost.This template has plate, grooved, perpendicular type various types simultaneously, is used for the concrete pouring of members, particularly its corner such as beam, post, is convenient to splicing and installs, and can effectively improve efficiency of construction.This template does not contain glass fiber, is of value to health.The utility model utilizes two plastic extruders to carry out layering progressive forming in conjunction with prior art when making, and through typing, cooling processing, can guarantee the template crudy.
Description of drawings
Fig. 1 is the utility model flat structure schematic diagram.
Fig. 2 is the utility model perpendicular type structural representation.
Fig. 3 is the utility model trench structure schematic diagram.
The specific embodiment
Referring to accompanying drawing, the utility model is made of top layer 1 and sandwich layer 2, selects 60 parts of polyethylene (weight portion, down with) for use, and 5 parts in 35 parts in aluminium hydroxide, liquid polyisobutene are through mixing, by sending into the 1# plastic extruder after the comminutor granulation; With 98 parts of polyethylene, 0.3 part of barium azodicarboxylate, 0.8 part in zinc oxide, 0.9 part of liquid polyisobutene, send into the 2# plastic extruder after mixing stirring, the compound of two extruders after with melting clamp-oned the layering shaping dies simultaneously, wherein 1# extruder compound enters the top layer, 2# extruder compound enters sandwich layer, extrude continuously and be processed into the thick 0.6mm in top layer, the tabular template of the thick 13.8mm of sandwich layer is as Fig. 1; Or the thick 1.0mm in top layer, the perpendicular type template of the thick 16mm of sandwich layer is as Fig. 2; Or the thick 0.8mm in top layer, the grooved template of the thick 16.4mm of sandwich layer is as Fig. 3.Certainly also can be processed into the template of other pattern as required.
Claims (2)
1, a kind of low foamed multi-layer plastic building template is characterized in that this template is made of sandwich layer and the top layer that is covered in the sandwich layer two sides, and template is plate, grooved or perpendicular type.
2, by the described construction formwork of claim 1, it is characterized in that the thick 0.4～1.2mm in described top layer, the thick 10～18mm of sandwich layer.
