Abstract
A gas-filled formwork of the utility model used for the architectural engineering construction can replace the exiting steel formwork and wood formwork. The utility model is characterized in that the steel products and lumber are saved, and the construction investment is reduced, and the engineering construction is accelerated. The mould is the curved surface such as cylinder coated and pieced by flexible high-strength and air-tightness materials such as polyvinyl chloride. The mould is one closed body, and a straight-way type gas-filled pore and an air bleeder are arranged on the gas-filled body and are shaped by a forming device, and a reinforcing steel bar bracket is arranged on the forming device. In the construction, the utility model makes use of an air compressor to fill pressure through the gas-filled pore on the gas-filled body, and the utility model is designed into the curved face under the control of the forming device. After the pressure in the gas-filled body reaches the pressure of the design, the moulding board of the concrete construction can be used. The utility model is suitable for the structure construction of the concrete curved face in particular.
Description
The utility model relate to a kind of in concrete engineering construction the novel die of moulding cast-in-place concrete structure, be particularly useful for the construction of concrete surface Structural Engineering.
Usually adopt steel form or wooden form at present in the construction of concrete surface structure.Not only time-consuming expense material when utilizing the construction of steel form or wooden form, and numerous and diverse cycle of construction sequence is long.Use simultaneously all bound keel system with matching of steel form and wooden form and support system and link securing member in construction, layer of structure is many.Template when using steel form or wooden form as the concrete surface structure construction also exists following several significant disadvantages:
1. get rusty owing to steel form is perishable, wooden form easily absorbs water and is out of shape breakage, so thereby the template poor durability causes turnover rate to hang down as wooden model can only be used 2-3 time.
2. the concrete surface stay in place formwork of steel form, wooden form moulding is manufactured difficulty greatly, for the different curved-surface structure of curvature different size, must do the different curve template and finish, so the circular formwork recycling rate of waterused of its a kind of size curvature is extremely low.
3. steel form, wooden form weight are big, and the molding form removal is wasted time and energy, and transportation is inconvenience and fragile very.
4. steel form, wooden form unit price height.
5. steel form, wooden form often have seam imprecision, phenomenons such as spillage.
Provide a kind of novel construction mould at above-mentioned problem the utility model--flexible inflation template.This flexible inflation template can effectively overcome the shortcoming that steel form, wooden form exist in the concrete surface structure construction, and have save steel, timber, cost is low, materials are few, moulding is easy, construction sequence is easy, convenient transportation, characteristics such as turnover rate height.
The purpose of this utility model is achieved through the following channels: use flexible material--and the inflation body that plastic-coated is made sealing replaces steel form or wooden form, utilize compressed air in the airtight inflation body to replace keel and support system in steel form and the wooden form, also avoid simultaneously using the connection securing member, control by shaping device makes inflation body after the pressurising by the design curved surface forming and reach design pressure, finishes the construction of cast-in-place concrete structure as template with this.
Describe concrete structure of the present utility model and working condition (is example with moulding semicylinder concrete culvert pipe with great template) in detail below in conjunction with accompanying drawing
Accompanying drawing 2 is flexible inflation body (1) material structure figure.Inflation body material is to constitute by being coated with polyvinyl chloride (11) inside and outside the textile (10), and inflation body seam crossing is the pressing of hot melt polyvinyl chloride.Sealing inflation body has very high tensile strength and tightness.
Accompanying drawing 3 is inflation body-shaping device (7) structure chart.Calibrator (7) is to be connected with bolt (14) with rough ground (13) by its two ends hole by band steel (12).Rough ground (13) links with pre-embedded bolt (27) with sole plate (26), and shaped form band steel (12) is established together every 50cm along semicylinder tubular structure length direction.
Accompanying drawing 4 is straight air-filled pore (a 2) structure chart.Its formation is to have setting-up piece and the screwed straight-through steel pipe of external surface (15) by an end termination to penetrate inflation body (1) and screw airtightly by plastic spacer (16) and steel plate washer (17) and spiral shell nurse (18), leads directly to the steel pipe ozzle and links to each other with source of the gas (5) with air gauge (4) by sebific duct.
Accompanying drawing 5 is vent valve (a 3) structure chart.Its formation be by an end have fixedly steel plate washer and external surface and the screwed steel pipe of other end ozzle (19) penetrate inflation body (1) and screw by plastic spacer (20) and steel plate washer (21) and spiral shell nurse (22) airtight, ozzle and air valve (23) airtight linking to each other of pore screw thread.
Accompanying drawing 6 is Steel bar rack (8) and calibrator band steel (12) johning knot composition.Steel bar rack is a φ 8M shape reinforced frame, and the band steel (12) in its bipod and the calibrator (7) is by weld seam (24) welding.The band steel (12) that has Steel bar rack (8) is established together at a distance of 1.5m.
Accompanying drawing 7 is scale (9) and Steel bar rack (8) johning knot composition.The rectangular scale of steel (9) and Steel bar rack leg with finer wire (25) up and down colligation be connected.
The utility model has following excellent compared with the prior art in the concrete surface structure construction Get over property.
1. saved steel, timber, reduced construction costs, the disposable cost of plastic-coated saves 30% than wooden model plate.
2. turnover rate height.The utility model turnover rate is much higher than steel form and wooden form.Turnover rate is more than 70 times.Wooden form is (2-3 time).
3. in light weight, volume is little, convenient transportation.Every square metre of flexible 0.05 kilogram of template weight of inflating.
4. molding, form removal are easy, and speed of application is fast, and the cycle is short, manufactures the precision height.
Adopt the utility model technology to water out the concrete culvert pipe with great of diameter 1m in the Harbin City.
