Inflatable mandrel zaoqiang Dong Xin teach you how simple construction methods and rehabilitation care

Do you know how many rubber balloon name it? Let ZaoQiang east bridge parts factory Meng Xin introduced one more name for your rubber balloon: precast hollow inner mold, precast hollow core mold rubber balloon, the inner rubber balloon model bridge precast hollow mold, mold rubber inflatable balloon mold hollow bridge, bridge balloon bridge plate mold core mold, bridge hollow slab airbags bridge plate within the mold, bridge plate rubber bladder hollow balloon mold, hollow mandrel inflatable mandrel hollow, hollow inner formwork ditches airbags, inflatable mandrel, Dong Xin balloon mold to provide you with one-stop shopping service: The picture does not exist the first step: the balloon is a kind of prefabricated bridge expansion and contraction of the cylindrical bag, used to form concrete chamber member, at the time of manufacture of hollow components, it will be placed in the middle, and filled with compressed air, when after the concrete has set, the release of compressed air bags, namely shrinking capsule, and the capsule can be withdrawn from the cavity. It is easy to use, economical and durable, not soft, inflatable can shrink any folded, curled, inflated after sufficient strength to withstand the pressure of concrete, which is unmatched by any of the traditional rigid template. For reinforced concrete pumping holes, including piles, roof trusses, roof pillar, underpasses and other components. Step two: bridge support is an important structural component connection superstructure and substructure of the bridge. It will bridge superstructure reaction force and deformation (displacements and rotations) reliable delivery to the bridge substructure, so that the actual situation and calculated the force structure in line drawings. Step Three: Bridge Expansion: Refers to the deformation of the bridge to meet the requirements, usually between two end of the beam, or set the position articulated joints on the bridge between the end of the beam and abutment. Requires expansion joints in parallel, perpendicular to the axis of the bridge in both directions, can freely scalable, secure and reliable vehicle should be smooth too, no sudden jump and noise; to be able to prevent the infiltration of rainwater and mud blocked garbage; installation, inspection, maintenance , to be simple and easy to eliminate dirt. Set expansion joints, railings and the bridge deck to be disconnected. Bridge expansion joints role: that regulation of the upper structure by the vehicle load and bridge materials caused by the displacement between and bonding. Skew bridge stretching device is damaged, it will seriously affect driving speed, comfort and safety, even cause traffic accidents. Optional accessories such bridges are not dispense with a lot of screening time, buy zaoqiang Dong Xin I will provide you full service. Thank you for your trust and support! The picture does not exist prefabricated bridge balloon, bridge rubber balloon construction method: 1, before use, first check the steel cage wire connectors and wire rolling head can not be bent radially inward direction, in order to avoid pricks mandrel to form an air leak. 2, the first concrete pouring steel cage bottom cushion, then pull the rope core mold steel cage, and the longitudinal seams facing up. 3. Open the valve inflated to a predetermined pressure to close the valve, should not be over-pressure. 4, shaped mandrel should be alternately inflated through a predetermined pressure. 5, will enter a steel cage around the mandrel up and down to be fixed. Overcome the buoyancy and move around. 6, after the pouring of concrete, using a vibrating rod vibration from both sides at the same time, preventing move around the mandrel. And the vibrator section head not touch the core module, so as not to puncture the leak. 7. After the initial setting of concrete, open the bleed valve, you can extract the core mold. (Demold time customized according to construction conditions). The picture does not exist construction proved balloon into the hole using prefabricated bridge technology, construction convenient, wide application and can be used repeatedly over 80-100 times, in fact, reduce costs and improve the construction progress of the tool of choice. Not only to save material, and has the shape changing characteristics, can be as round, oval, rectangular, arched, octagonal, trapezoidal and other pipeline. You can also become straight hole, variable cut faces, etc., can become light building structures, thin-walled hollow, concrete has been used to change the status of rigid template. Drawings provided by Our customers can customize the shape of diverse, complete specifications, price concessions, quality assurance.
