5 thoughts on “Drainage cast iron pipe fixed bracket setting requirements”

  1. 1. Pipelines, waterproof sleeves wearing underground outdoor walls, reserved holes and other engineering measures refer to the national architectural standard design atlas “Installation of Flexible Interface Masting Iron Pipes for Building Drainage” 04S409.
    2, the allowable deviation of the vertical deviation of the drainage riser to install the vertical degree of the unit tube (1m) should not be greater than 3mm, and the total length (more than 5m) should not be greater than 15mm. The slope of the drainage should meet the design requirements, and there are strictly prohibited phenomena of slopes and slopes.
    3. During the construction and installation of the pipeline system, the pipeline shall not be used as a pull, hanging frame, and bracket. The opening of the pipeline should be blocked in time.
    4. When installation of flexible interface drainage and cast iron pipeline system, the sign of the direct pipe and the outer wall of the pipe should be set in a clear position.
    5. The flexible interface cast iron pipe and its supporting pipes, connectors, etc. used for the construction drainage pipeline project must adopt the same product model and specifications, and have a unified tolerance. The brackets (tube card), brackets, and suspension of the installation and fixed pipeline should be supplied by the production plant provided by the pipe.
    6. During the construction stage of the building’s civil construction structure, the installer should cooperate with the reserved holes, embedded parts, embedded sleeves, and other load -bearing structures such as drainage pipes through the wall, pool wall, floor, and concrete beam. Work.
    7. When the cast iron direct tube needs to be cut, the end surface of the incision should be perpendicular to the direct tube axis, and the incision should be polished smoothly.
    8. When the building drainage flexible interface card hoop -type cast iron pipe is connected to the plastic tube or steel pipe, if the outer diameter of the two is equal, the standard card hoop and standard rubber sealing ring can be used. Special transition parts for rigid interfaces to flexible interfaces may be sealing in non -standard card hoop and different diameter non -standard rubber sealing rings specially made by manufacturers.
    9. When the building drainage riser is laid along the corner of the corner, the bolt position (card hoop type) of the bolt (card) or the bolt holes of the bolt hole of the flange cover and the rubber sealing ring is used to fix the bolt. (Frankage) should be adjusted to the outside of the corner to facilitate the tightening bolt.
    10. When installing the product installation according to the “Flexible Interface Casting Iron Pipe and Pipe Pipe Pipes and Pipe Pipes for Drainage Drainage”, the rubber ring surface should be properly placed.
    11. Flexible interface drainage cast iron direct pipes, pipes and interface parts must not be adopted with signs of damage. For long -term storage products, appearance inspections should be performed before use.
    12, the pipelines, pipes and parts used by the building drainage flexible interface cast iron pipeline project, the materials, specifications, size, and technical requirements of the materials, specifications, size and technical requirements should meet the current national standards or industry standards.
    Pucting data
    The precautions for using cast iron pipes:
    1, W -type pipe uses a flat oral connection to high requirements for the quality of the pipe, the outer diameter, wall thickness and rubber ring of the drainage cast iron pipe Performance has higher requirements.
    2, the installation and construction of the W -shaped tube should be implemented strictly in accordance with the operation process. Especially when the pipe interface is installed directly, the vertical card is required to be fixed on the load -bearing wall of the building; the horizontal tube should be added at each interface.
    3, T -type interface pipes should be set up at the vertical or horizontal turn. The size of the pier shall be determined according to factors such as pipe diameter, corner, and work pressure.
    The connection of the cast iron pipe adopts a inheritance or flange plate method.
    The connection between the tube and the tube adopts the form of an inheritance or flange plate interface; according to the function, it can be divided into two types: flexible interface and rigid interface. The flexible interface is sealed with a rubber ring, which allows a certain limit to corner and displacement. Therefore, it has good seismic resistance and sealing, which is simpler and fast than rigid interface installation. According to the casting method, the labor intensity is small.
    The cast iron pipe is used to transport pipelines for water, drainage and gas, which includes cast iron direct pipes and pipes. Little labor intensity. According to the casting method, it is divided into continuous cast iron pipes and centrifugal cast iron pipes. Among them, the centrifugal cast iron pipe is divided into two types: sand and metal. Different materials are divided into gray -mouth cast iron pipes and ball ink cast iron pipes. It is divided into flexible interfaces, flange interfaces, etc. according to different interfaces.

  2. 1. Pipeline branches (hanging) frame
    1.1 building drainage flexible interface cast iron pipe installation, the upper pipeline weight should not be passed to the lower pipeline. The weight of the riser shall be forced by the bracket, and the weight of the cross -tube shall be forced by a branch (hanging) frame.
    1.2 Pipeline branches (hanging) frame positions should be correct, and the burial should be firm. The contact card or suspension card should be tightly contacting the pipeline and shall not damage the outside of the pipeline. In order to avoid electrochemical corrosion of stainless steel card hoop, the bearing tube or suspension card of the drainage cast iron pipe of the card hoop interface should not be set in the card hoop. The pipelines should be metal parts and are treated with anticorrosive treatment.
    1.3 Drainage vertical pipe should be fixed at each layer. The spacing distance should not be greater than 1.5m, but only one riser bracket can be set when the layer height is less than or or equal to 3M. The card hoop interface standing tube card should be set under the card hoop at the interface. The flange -proof interface pipe tube card should be located below the promotion, and the net distance from the interface should not be greater than 300mm.
    1.4 Drainage horizontal pipes should be set up with two triability every 3M tube, and the rack should be set up close to the interface. On the side of the promotion), the net distance between the interface should not be greater than 300mm. When the drainage tube turns on the plane, a rack should be added at the elbow. The upper end of the drainage and the terminal should be fixed with anti -shaking brackets or anti -shaped suspension racks. The drainage stem tube is fixed with a bracket or suspension, and the spacing distance of the tributary should not be greater than 1.2m. When the length of the horizontal dry pipe is long, in order to prevent the horizontal displacement of the pipeline, the spacing of the front -line section of the straight line section or the anti -shaking frame should not be greater than 12m. 1.5 Pipeline stent or tube card should be fixed on the middle side of the beam, under the board or bearing structure. The tube -tube suspension should be used to use independent tube cards as much as possible, and the overall hushed with corner steel is used. The tube dense parts should be built under the beam in the beam. The fixing of the steel beam holding pipe uses a dedicated steel beam tube or rivet. Each layer is equipped with a tube (when the height is greater than 5m, 2 is set on each layer), and the installation height is 1.5-1.8m from the ground.
