Description
Technical field
The utility model relates to construction formwork, particularly a kind of construction formwork of Plastic Welding.
Background technology
Template is a construction tool important in the structure construction, and form work engineering generally accounts for the 20-30% of reinforced concrete work expense, accounts for the 30-40% of the amount of labour, accounts for about 40% of the duration.Therefore, the raising of mould plate technique can reduce construction cost, save the labour and speed up the work, and to improving building level important meaning is arranged.
At present, in engineering construction, horizontal shuttering is mainly wooden form, comprises two kinds of bamboo offset plate, wood plywoods.The vertical formwork kind is more, and in Beijing, the higher area of construction technology levels such as Guangdong, Shanghai is based on large steel moulding plate, part adopts wooden form and little punching block, and the relatively low area of other building level is then based on little punching block.Wooden form range of application in engineering construction is the widest, both can be used as horizontal shuttering and has used, and also can be used as vertical formwork and uses.But owing to be subjected to the restriction of China's timber resources, wood plywood output at home is not high, and is in the majority with bamboo offset plate and steel form on the market.But Bamboo Formwork uses the number of turnover less, and actual use has belonged to difficult above 10 times, and the general number of turnover is 5-8 time.That Bamboo Formwork has is cheap, the advantage of light weight, but that bamboo glue pattern plate waters the metope that outpours is of low quality, can not satisfy the construction requirement of high level.The steel form number of turnover is many, generally greater than 100 times, but owing to its price height, than great, is unfavorable for construction, and because the restriction of material itself is big with concrete adhesion stress, is unfavorable for demoulding.
At present construction formwork begins to develop towards the composite material direction, its have in light weight, be easy to the demoulding, advantage that repeat usage is high.Composite material building mould board is more representative just like Chinese utility model patent number 200420089307.5 disclosed composite material building mould boards, this construction formwork comprises upper layer, following surface layer and sandwich layer, its sandwich layer is between upper layer and following surface layer, described upper layer is frp layer with following surface layer, accompanies bonding layer between frp layer and the sandwich layer.The moulding of above-mentioned frp layer is composited by fiber reinforced material, filler and laminated resin, and its thickness is 0.5-10mm; Wherein fiber reinforced material is one or two or more kinds combination in glass fabric, glass felt or the glass fiber; Filler is selected for use in aluminium hydroxide, calcium carbonate, glass microballoon or the acicular wollastonite at least a; Resin is combination at least a in epoxy resin, phenolic resins or the mylar; Form through the press compacting.Sandwich layer is a kind of in Cellular board or the foam central layer.Bonding layer is by fiber reinforced material and adhesive solidification and form, and wherein fiber reinforced material is one or two or more kinds combination in glass fabric, glass felt or the glass fiber; Bonding adhesive can be selected for use in epoxy resin or the mylar a kind of.
Above-mentioned composite material building mould board adopts slabbed construction, can the cutting assembly unit; The fiber reinforcement mask has enough intensity, and it uses the number of turnover can reach 50 times, and strong erosion resistant ability is arranged; Control the thickness and the surface finish of this composite material building mould board by the combination of mould or press or mould and press, its construction quality is higher than the quality of Bamboo Formwork, and template density is far below steel form.The composite material template surface is little to concrete adhesive power, is convenient to the demoulding, helps building out smooth metope.
The applicant once applied for similarly patent, China Patent No. is 200710036384.2 disclosed a kind of construction formwork and injection molding forming method and moulding forms, it is to be made of a working panel and the reinforcement gusset that is positioned at the working panel back side, it is more environmental and durable than the construction formwork of existing glass fiber reinforced plastics composite material, and therefore described construction formwork is still waiting further improvement.
The utility model content
Technical problem to be solved in the utility model is, overcomes the disadvantage that the existing building template exists, and a kind of construction formwork of Plastic Welding is provided, and makes easily, and cost is low, and is sturdy and durable, easy to use.
In order to address the above problem the technical solution of the utility model is such:
A kind of construction formwork of Plastic Welding is formed by the glass fiber reinforced plastics injection, the reinforcement gusset formation that it comprises the two layers of plastic working panel and is positioned at the plastics working panel.
Described two layers of plastic working panel is composited by the welding of higher-order of oscillation friction process, and the reinforcing rib on the working panel is arranged tightr, and therefore under the effect of high-frequency frictional oscillation, the two layers of plastic panel is directly integrally welded;
The reinforcement gusset that is positioned at the two layers of plastic working panel also can be welded in one under the high-frequency frictional oscillation effect.The corresponding welding of reinforcing rib in the described two layers of plastic working panel can prevent that the impurity such as wood chip of a side are splashed to opposite side.
The described reinforcement gusset that is positioned at panel comprises that gusset is strengthened at the edge that surrounds shaped as frame and the middle gusset of strengthening constitutes.The middle gusset of strengthening becomes cross-shaped, and becomes the T font to intersect with the reinforcement gusset at edge.The thickness of described reinforcement gusset is 2-6mm, adopts round-corner transition at its infall.Between the reinforcement gusset at described edge and working panel, be provided with the dihedral reinforcing rib.Be provided with T shape in the intersection of the reinforcement gusset at described edge and connect gusset.
Consider the requirement of Shooting Technique and structural strength, the glass fiber reinforced plastics that the utility model adopts is a glass fiber reinforced polypropylene.Adopting glass fiber is that length is the 0.3-5mm short fiber.
Construction formwork connects in flakes for convenience, offers the construction formwork connecting through hole on the reinforcement gusset at described edge.
The beneficial effects of the utility model are, and are more sturdy and durable by the construction formwork that the two layers of plastic working panel is composited, easy to use; This construction formwork strengthens by gusset, and intensity is good, and the template after damaging can recycling, than the construction formwork environmental protection more of existing glass fiber reinforced plastics composite material.
Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is the structural representation of one deck working panel of the present utility model.
Fig. 2 is the structural representation of another layer working panel of the present utility model.
The specific embodiment
