1, the construction of bagging mode: The template is two-way board should be two-way camber, single board should check bagging, bagging height template center layer between 3 ~ 5 ‰, the second floor and the second floor above the Template Center from arch height between 2 ~ 3 ‰. 2, can not throw to the ground when the hollow tube shipped directly after reaching the construction site unload thin tube, neatly stacked, heavier objects shall not be used to hit the hollow tube and the pressure placed on the ground and reinforced to stabilize. When installing the hollow tube must be handled with care, in a hollow tube installation construction personnel shall not directly in the hollow tube walk on thin tubes of building materials should be days before walking should be laid on top of the hollow tube of wood, shall not be stacked directly on top of the hollow tube weight material and other jobs. Lifting must be used to install a dedicated hanging blue lifting. Do not use a direct cable lashing lifting hollow tube, hollow tube was hanging to the floor after installation should be discharged, should not be re-stacked pile. Unidirectional reinforcement prestressed hollow plate unit schematically - thickness 800 prestressed hollow plate unit bidirectional reinforcement schematically - thickness of 7003, vibrating method: not buried in concrete poured on top of the hollow tube accumulate more concrete, put the End Concrete should immediately spread vibrating, less water must adhere to the ground shake, prevent exposed reinforced floor below the phenomenon. When the vibrating concrete easy to choose d = vibrating rod 30 may not be used vibrating plate [4]. 4, the hollow tube pitch control: Before pouring the concrete can be used to pull out the wooden post wooden thin tube 60 × 60 is inserted between the two hollow tubes, until the concrete pour to fill the initial setting of each rib and then concrete the hole filled by the wooden form [4]. 5, concrete pouring methods: a hollow tube sideways direction should be poured concrete, the center began pouring from the plate, and then from the center to the periphery of the pouring diffusion method, or with a fixed inner mold steel fork, fork live within a few rows in the casting mold After the vibration is complete, extract the next row of steel fork fixed a thin plastic tube, and so on. Great span prestressed hollow floor construction process because of operational requirements, Yancheng Building Materials Co., Ltd. for the country should be days, invites all over the institute, and the community to cooperate hollow floor project, I plant to provide hollow floor with the design, hollow floor mandrel production and supply, technical guidance hollow floor installation, integration services, so you worry-free; professional manufacturers give you professional products and services, high-return, risk-free, cooperation and win-win; the other country Employment hollow floor project sales, especially in the construction business experience are welcome materials, those contacts to join, and to expand and open-situ concrete hollow floor of this national policy support, with a huge potential market, a promising career prospects and more! Warm welcome to inquire! Thin tube, Guangzhou thin tube, should be days should be days of building materials by the Yancheng Building Materials Limited. Yancheng should be days of Building Materials Co. (ycytjc.com) (www.ycytjc.com) strong, credible, Yancheng in Jiangsu Province building materials processing industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas should be days of building materials will lead into the brilliant and you work for a better future!
