300 * 10 220 * 10 bridge inflatable rubber mandrel use

300 * 10 220 * 10 bridge inflatable rubber mandrel use precast slab rubber mandrel Save: prefabricated rubber mandrel mandrel, hollow inner beam inflatable mandrel, hollow plate girder mandrel, hollow plate girder core mold, precast slab Cheung Lee rubber mandrel rubber manufacturers. Plate girder balloon mandrel by vulcanizing rubber and fiber reinforced layer made with high tensile strength, elasticity and tightness, concrete elements used to form a cavity, in the manufacture of hollow components, put it in the middle, and filled with compressed air, inflated after sufficient strength to withstand the pressure of concrete, can replace the original wooden mold, bamboo mold, steel, open the valve octagonal inflatable mandrel is contracted and star anise can be withdrawn from the cavity inflatable mandrel. It is easy to use, economical and durable, can be repeatedly used, not soft, inflatable can shrink any folded, curled, for reinforced concrete pumping holes, including piles, roof trusses, roof columns, beams, construction, hydraulic engineering (dock , berth, quay). Prefabricated bridge inflatable hollow mandrel custody and maintenance: prefabricated bridge mandrel rinse with water after use, if you want to be careful scraping cement attached. Rotary dry air, to prevent the sun and rain, do not touch the fire source. No contact with oils and organic solvents. Do you want to pay attention to when using sharp hard objects will not let prefabricated bridge mandrel punctured. Prefabricated bridge mandrel if air leaks, use wheel or rasps its surface roughening, after the use of gasoline to clean, repair coated adhesive tape covering film. Hollow balloon balloon hollow mandrel mandrel, low prefabricated slab rubber balloon mandrel price, quality assurance, round, octagonal, oval, adjustable and chamfered, oblique, orthogonal custom processing are all available, hollow mandrel balloon in the manufacture of hollow components, put it in the middle, and filled with compressed air, with the inner diameter of the hollow plate girder fully consistent and have sufficient strength to withstand the inflated after concrete pressure balloon hollow mandrel | octagonal inflatable mandrel pumping holes process equipment is simple, not only to save material, reduce costs but also greatly speed up the construction progress of the project, thriftiness of the human and financial resources and material resources, is to create a concrete precast hollow beam engineering the best choice, please call us or visit our factory, your support is our glory. dn160mm inflation pressure 0.08Mpa, dn200mm inflation pressure 0.07Mpa, dn240mm inflation pressure 0.05Mpa, dn230mm inflation pressure 0.06Mpa, dn260mm inflation pressure 0.05Mpa, dn390mm inflation pressure 0.04Mpa. A rubber mandrel into the mold A rubber core mold surface evenly release agent. B with a rope pulling the rubber end of a mandrel penetration of concrete reinforcement cage, and inflatable rubber mandrel placed outside the mouth. A two inflatable open the inlet valve of the inflatable rubber mandrel. Inflatable air pressure with a pressure gauge control monitoring. B when the air pressure to use air pressure, the intake valve closes. C-shaped rubber mandrel should be alternately inflated until use air pressure. D Note that no excessive pressure when used. 3 A fixed and pouring concrete when the concrete vibrator pound rubber mandrel will go up, therefore, must be fixed up and down, generally 250MM diameter mandrel stirrup spacing 80cm, such as diameter increased, the spacing corresponding narrowing. 96 B pouring concrete building methods and is the heart of the same, note the use of high-frequency vibration rod inserted or pound pound vibration simultaneously from both sides, to prevent rubber 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 core mold rubber, removal time visualization number of cement. kbx 5 Rinse rubber mandrel, test the water test. Please take off in order to keep reusable rubber mandrel
