Abstract
The utility model relates to the technical field of building formworks, in particular to a PVC building formwork. The PVC building formwork comprises a formwork body, the formwork body is composed of three layers of pressing plates and two layers of stiffening plates, each layer of stiffening plate is arranged between every two layers of pressing plates, the thickness of each pressing plate is 2-4mm, and the thickness of each stiffening plate is 2-3mm. When the PVC building formwork is used, the intensity of the PVC building formwork can be enhanced through the stiffening plates. Compared with the prior art, the PVC building formwork has the advantages that the weight is low, a large-scale hoisting device is not required when the formwork is assembled and disassembled, automatic demolding can be achieved without releasing agent in the construction process, and construction time is saved; damp-proof, waterproof and anti-corrosion purposes are achieved; the service life is long, and the use frequency is two to five times of that of the a high-quality bamboo plywood; recovery processing and secondary utilization are achieved, influence to the environment is little. In addition, the PVC building formwork further has the advantages of being reasonable in arrangement, low in manufacturing cost and the like.
Description
Technical field
The utility model relates to the construction formwork technical field, particularly a kind of PVC construction formwork.
Background technology
In recent years, China every year approximately newly-built 2,000,000,000 square metres of buildings, at the bottom of expecting the year two thousand twenty, national house architectural area will increase 40,000,000,000 square metres newly, its asd number and construction speed are all unprecedented mistakes.Due to the building structure of China take cast-in-place concrete structure as main body, and the construction formwork important tool that is absolutely necessary in the cast-in-place concrete structure work progress, form work engineering is the important step in the concrete structure construction process, and construction formwork directly has influence on quality, progress and the cost of construction work.The utilization of adopting what material to make construction formwork to be related to resource, the cost of production of template and to the construction cost of building and cause influence degree to environment.
At present, the template mainly used of builing industry has steel form, wooden form, Bamboo Formwork.Steel form is mainly used in civilian height and lives outer wall template, Pier Formwork, bridge engineering plane and special-shaped part, its than great, once infusion of financial resources amount large, maintenance cost is high, use is inconvenient; Wooden form, Bamboo Formwork are mainly used in civilian commercial and residential building, plane bridge engineering, are bonding with phenolic resins or pollopas, and one has low toxicity, its two, the very thin thickness of glue-line, its three, can not bending forming, can not satisfy the requirement of curve modeling.When timber or bamboo wood immersion dilatancy, the extension at break degree of glue-line is far smaller than bamboo wood dilation, so the stratification of coming unstuck will appear in sheet material, Here it is, and the bamboo and wood template is not durable, the main cause that repeat usage is low, be generally 3-8 the application life of bamboo and wood template.
Along with quick people's exhibition of national economy, the urban traffic pressure is outstanding day by day in addition, and setting up overpass bridge is one of Main Means that slows down traffic pressure, and wherein the arc bridge extensively adopts in overpass bridge with its beautiful design.But the arc bridge is for the rectangle bridge, the installation of its modular system and reinforce more complexly, and the arc bridge does not reach the requirement of technical specification and geometric shape according to traditional fixing of the forming frame at all.Wherein, common steel form will bend to many curved profile difficult, and expense is higher; Commonly used wood glue plate, bamboo blanket template be more difficult bends shaping.
Therefore, in building and bridge construction industry,, intensity low in the urgent need to a kind of template cost of production and pliability are good, can carry out arc and process; Easy to loading and unloading, save the man-hour of constructing; Waterproof, anticorrosion, the number of turnover is many; Recyclable processing utilizes again, and the mould material little to ambient influnence to improve quality and the progress of construction project, reduces the construction cost of building and bridge construction engineering, reduces the consumption of natural resource.
The utility model content
The purpose of this utility model is for the defective of prior art and deficiency, and PVC construction formwork a kind of simple in structure, reasonable in design, easy to use is provided.
For achieving the above object, the technical solution adopted in the utility model is: a kind of PVC construction formwork, comprise template body, described template body is comprised of three laminates and two-layer stiffener, described stiffener is arranged between two laminates, the thickness of described pressing plate is 2～4mm, and the thickness of described stiffener is 2～3 mm.
Further, described stiffener is comprised of a deck panels and two-layer ribs, and two-layer ribs is separately positioned on upper surface and the soffit of panel.
Further, described ribs is the net structure distribution.
Further, the thickness of described pressing plate is 2.5～3.5mm, and the thickness of described stiffener is 2.2～2.8 mm.
Further, the thickness of described pressing plate is 2.8mm, and the thickness of described stiffener is 2.4mm.
Further, the thickness of described ribs has 0.8mm at least.
After adopting said structure, the utility model beneficial effect is: a kind of PVC construction formwork described in the utility model, comprise template body, described template body is by three laminates and two-layer stiffener, described stiffener is arranged between two laminates, the thickness of described pressing plate is 2～4mm, and the thickness of described stiffener is 2～3 mm.When using the utility model, but by stiffener Reinforced PVC construction formwork intensity, the utility model compared with prior art, it has the following advantages.
The first, template quality is light, and loading and unloading do not need Large-scale Hoisting equipment, but do not need the release agent automatic demoulding in work progress, saves the man-hour of constructing.
The second, the advantages such as protection against the tide, waterproof, anticorrosion.
The 3rd, long service life, access times are 2--5 times of high-quality bamboo offset plate.
The 4th, recyclable processing utilizes again, and is little to ambient influnence.
Five, can carry out arc processing, the alternative steel form of the arc-shaped plate after processing.
The 6th, the utlity model has simple in structurely, the advantage such as cost of manufacture is low is set rationally.
