Rubber inflatable mandrel, are made of rubber and fiber reinforced layer made of vulcanized products with high tensile strength, elasticity and tightness, back filled with compressed air, to replace the original wooden mold, bamboo mold, steel mode. Can be used repeatedly, it is a lower cost and speed up the construction progress of concrete products supporting products. ? Rubber inflatable mandrel Use 1 rubber inflatable mandrel into the mold A rubber inflatable mandrel release agent surface evenly. B with a rope pulling the rubber inflatable mandrel penetration of the end of a concrete reinforcement cage, and inflatable rubber inflatable mandrel placed outside the mouth. 2 Inflatable A open the inlet valve of the inflatable rubber inflatable mandrel. Inflated with air pressure gauge control monitoring. B when the air pressure to use the pressure, the intake valve closes. C-shaped rubber inflatable mandrel should be alternately inflated until use air pressure. Overpressure D may not pay attention to use. 3 A fixed and pouring concrete at the pound concrete vibrator rubber inflatable mandrel will go up, therefore, it must be fixed up and down, generally 250MM diameter mandrel stirrup spacing 80cm, such as diameter increased, the spacing corresponding narrowing. B pouring concrete method is basically the same heart to build, pay attention to use high-frequency vibration rod inserted or pound pound vibration simultaneously from both sides, to prevent rubber inflatable mandrel about displacement. Pound vibrating rod ends is best not to touch the core module. 4 form removal when the initial setting of concrete, open the bleed valve, you can extract the rubber inflatable mandrel, the removal time depending on number of cement visible. 5 Rinse rubber inflatable mandrel, test the water test. Please keep off the rubber inflatable mandrel to be reused. Round balloon mold rubber production, also known as circular rubber inflatable mandrel, is the product made of rubber and fiber reinforced layer made of vulcanized with high tensile strength, elasticity and tightness, filled with compressed air After, to replace the original wooden mold, bamboo mold, steel. Can be used repeatedly, it is a lower cost and speed up the construction progress of concrete products supporting products. ? Specific methods are as follows: 1, into the mold A, in the balloon mold surface evenly release agent. B, with a rope pulling the end of a balloon mold penetration of concrete reinforcement cage, and to be placed outside the inflatable at the mouth. 2, inflatable A, open the inlet valve inflated, inflated with pressure gauges to monitor the control pressure (gauge vertically) B, when the pressure to use the pressure, the intake valve closes. (See the following balloon using a pressure gauge) C, shaped balloon model should be alternately inflated until the pressure. D, note that no excessive pressure inflator. 3, fixed and pouring concrete A, when the balloon mold vibrated concrete will go up, therefore, must be up, down, left and right to be fixed, usually 250mm balloon mold stirrup spacing 80mm, such as walking diameter increased, the spacing reduced accordingly. B, pouring concrete and solid components are substantially the same, note the use of high frequency inserted vibrators or vibration from both sides at the same time, to prevent the balloon mold about displacement. Vibrating rod ends is best not to touch the balloon model. 4, form removal when the initial setting of concrete, open the bleed valve, you can extract the balloon mold, removal time depending on number of cement visible. 5, washing capsules, pressure test inspection. Circular inflatable mandrel (balloon mold) custody and maintenance of A, rinse with water after balloon mold using a clean, dry place when not in the rotation, do not touch the oil, acid and alkali. B, field use to avoid touching sharp hard objects. C, balloon mold after ejection time, immediately brush (nylon brush is best) tap water to remove the concrete surface to keep clean the inside of the airbag module. D, balloon mold, if any leakage, sealing off the film is to be in need of repairs at the wheels for grinding, brushing glue patch covering film, fiber tear repair coverage at Zeyi tape ● The main technical parameters of the balloon and the endometrium Note: 1, (1) the balloon inflation pressure and diameter of the balloon endometrial, pouring new concrete construction temperature pressure and other factors. Balloon pressure remains within 0.02-0.025MP (round or oval), 0.015-0.022MP (octagon, of spherical, inverted ladder) range (see cover balloon endometrial pressure) Reserved Hole Aperture meet regulatory requirements, to achieve the desired effect. (2) The deflated balloon endometrial and construction time temperatures, generally complete after pouring the concrete surface of the finger can be pressed out of the fingerprint and concrete deformation can be deflated. 2, the air bag must brush endometrial use a release agent, in order to reduce pumping mold resistance, balloon endometrial insufficient
