Abstract
A building template made of pultrusion composite materials comprises panels and reinforcing ribs, wherein the two side panels are connected through the reinforcing ribs to form a hollow structure. The outer walls of the reinforcing ribs on the two sides of the template are provided with splicing tongues and grooves which are yin-yang type tongues and grooves or concave type tongues and grooves. The building template is integrally and continuously molded by adopting a composite material pultrusion process.
Description
Technical field
The present invention relates to a kind of construction formwork, especially a kind of lightweight, high-strength, corrosion resistant building template molded through pultrusion of composite material generally are used for the building large form of large tracts of land flooring, wall construction, belong to the realm of building construction.
Background knowledge
Along with the increase of China's highrise building, cast-in-place load bearing wall is more and more, and the template of bulk uses chance also to increase thereupon, can effectively save man-hour, reduces piece, therefore presses for the novel high-strength light of research and development, the building large form of environmental protection.The concrete construction formwork that present building trade is generally used has wooden agglutination formwork, bamboo plywood form, steel form and plastic formwork etc.
And because wood (bamboo) veneer water absorption rate height, yielding, the corrosion of template has often only been had enough to meet the need and just had to several times abandon, and is very huge to the influence of resource and environment.And the steel form deadweight is bigger, uses engineering machinery to install, dismantle during use inevitably, and construction cost increases, and especially is not suitable for high-building construction, and the steel form one-time investment is big in addition, use and the maintenance cost height, and piece is also more; The Admixture that adds during concreting now simultaneously is more, easily punching block is caused chemical attack.And plastic formwork also exists that strength and stiffness are lower, heat resistance and durability is relatively poor, the more high shortcoming of price.
Fibrous composite has that high-strength light, rigidity are big, corrosion-resistant, the remarkable advantage of weatherability.Pultrude process is that fiber bundle or fabric are fed continuously by creel, process resin glue groove is with fiber impregnation, enter withdrawal mechanism after passing hot forming tool again, can be made into continuous composite product by this flow process, pultrude process can be produced the continuous section bar of cross sectional shape complexity.Therefore the pultrusion molding process that can adopt serialization to produce prepares the large-scale composite material construction formwork, its main innovation is the cancelled structure that its ribs strengthens, under the prerequisite of the lighter weight that guarantees template, can significantly strengthen the rigidity of template, be used for flooring and wall construction.
Summary of the invention
The objective of the invention is to develop a kind of novel building template molded through pultrusion of composite material in order to adapt to construction formwork high-strength light, corrosion-resistant, the high requirement of turnover access times.
Purpose of the present invention can reach by following measure:
A kind of building template molded through pultrusion of composite material comprises panel and ribs, constitutes cancelled structure by the ribs connection between the panel of described both sides.
A kind of building template molded through pultrusion of composite material comprises panel and ribs, constitutes cancelled structure by the ribs connection between the panel of described both sides, and template two side stringer outer walls are provided with the splicing tongue and groove, and the splicing tongue and groove is negative and positive type tongue and groove or matrix tongue and groove.
Described building masterplate adopts composite material pultrusion technology integral body continuously shaped.
Described building masterplate is that fiber bundle or fabric and resin solidification form, and fiber bundle or fabric comprise: glass fiber, basalt fibre, aramid fiber or carbon fiber; Resin comprises: unsaturated polyester (UP), vinylite, epoxy resin or phenolic resins.
The present invention has following advantage:
Building template molded through pultrusion of composite material of the present invention is compared with other products, and its maximum characteristics are: in light weight, and the intensity height, rigidity is big, and is corrosion-resistant, and assembling construction is simple, convenient and rapid, turnover access times height.But this building template molded through pultrusion of composite material suitability for industrialized production simultaneously can be produced the construction formwork of different size (thickness and ribs are variable) by use field and load bearing requirements.

Fig. 3 is the user mode schematic diagram of construction formwork of the present invention.
In the accompanying drawing: 1, panel; 2, ribs; 3, splicing tongue and groove; 4, i beam supports; 5, metallic support.
The specific embodiment
Below in conjunction with drawings and Examples the present invention is further described:
As shown in Figure 1, constitute cancelled structure by ribs 2 connections between the both sides panel 1 of the composite material building mould board of pultrusion of the present invention, both sides panel 1 is strutted by ribs 2, improved second moment of area, form the bigger template of rigidity, can link to each other by splicing tongue and groove 3 between template and the template, also can not establish this tongue and groove, the globality of enhancement mode plated construction.Construction formwork can adopt the pultrude process serialization to produce, raw material can adopt glass fiber, basalt fibre, carbon fiber etc., fiber bundle or fabric are fed continuously by creel, process resin glue groove is with fiber impregnation various types of resins such as unsaturated polyester (UP), vinylite or epoxy resin, enter withdrawal mechanism after passing the shape thermoforming metal die consistent again, can be made into continuous composite material building mould board by this flow process with shape of template.Because fiber mainly vertically in the drawing and extruding section bar, and fiber content height, good stress performance is arranged, can be directly as primary structure member, especially the wall form that can be used for single load bearing, but the transverse strength and the shear strength of drawing and extruding section bar are lower, therefore also can be in pultrusion molding process at the chopped mat of the peripheral compound some of section bar.Fig. 2 is the cross section of different shape pultrusion construction formwork, as Fig. 2 (a) is the flat die plate that does not have tongue and groove, Fig. 2 (b) is the flat die plate that is provided with splicing tongue and groove 3, and Fig. 2 (c) is the flat die plate that is provided with matrix splicing tongue and groove 3, and Fig. 2 (d) is the curved surface shaped template that is provided with splicing tongue and groove 3.After linking to each other by splicing tongue and groove 3 between the template, by i beam support 4 and metallic support 5 constitute template system, referring to Fig. 3.
As shown in Figure 2, the ribs that both sides panel 1 and ribs 2 constitute template strengthens cancelled structure, be prepared from by the pultrude process serialization by fiber bundles such as glass fiber, basalt fibre, carbon fiber or fabric, also can be in pultrusion molding process at the chopped mat of the peripheral compound some of section bar, component shape is consistent with the mold shape of being opened.
Splicing tongue and groove 3 is the joint construction measure between the adjacent forms, and during assembly unit, template gets final product by 3 clampings of splicing tongue and groove.Also tongue and groove be can not establish, negative and positive tongue and groove, matrix tongue and groove also can be established.
As shown in Figure 3, i beam support 4 and metallic support 5 constitute template system with template, form floor template, wall form, column template etc.
