The specific embodiment
To shown in Figure 5, cement rod connecting flange of the present invention comprises connecting portion and installation portion as Fig. 1, and wherein, installation portion comprises flange 1, circumferentially is provided with installing hole 11 in flange 1 upper edge, upwards is extended with two card platforms 12 at least in the footpath of flange; Connecting portion comprises card circle 4, and card circle 4 upper edges circumferentially evenly are provided with many group reinforcing bar connecting holes 41, and every group of reinforcing bar connecting hole comprises two connecting holes at least, and also is provided with alignment concavity on connecting hole.4 on flange 1 and card circle are connected and fixed by a steel ring 2, and steel ring 2 upper edges circumferentially are provided with strengthens gusset 3, fixedly connected with card circle 4 with flange 1 respectively in the two ends of strengthening gusset 3.Also be provided with an external partition 5 between flange 1 and the card circle 4, be airtight being connected and fixed between the external surface of external partition 5 and steel ring 2; The inside of steel ring 2 also is provided with an internal partition 6, is airtight being connected and fixed between the inner surface of internal partition 6 and steel ring 2; When making cement pole, external partition 5 and internal partition 6 play the effect that restriction cement covers the position, prevent that cement from overflowing flange face, and internal partition 6 can be wrapped among the cement bonding strength between further refinforced cement club shaft and the cement rod connecting flange.
Cement rod connecting flange of the present invention adopts the high-tenacity nodular cast iron manufacturing, material is QT450-10, ferrite quantity in making processing procedure in the control material is more than 85%, pearlite quantity is below 15%, nodulizing grade reaches in " rare-earth magnesium ball iron metallographic standard " more than two, three grades, based on spheroidization of graphite, all the other are evenly distributed for bulk.Its part constituent content is: C content is 3.4%～3.6%, and Si content is 2.2%～2.8%, and Mn content is less than 0.3%, P content is less than 0.06%, S content is less than 0.06%, and Mg content is 0.04%～0.06%, and RE (rare earth residual volume) content is less than 0.04%.The elongation per unit length that can guarantee this material thus is that tensile strength is at 500N/mm more than 16%
2More than.
When utilizing cement rod connecting flange of the present invention to make cement pole, earlier two cement rod connecting flanges are fixedly clamped in the relative mode of its connecting portion, and guarantee both concentricity, in corresponding reinforcing bar connecting hole 41, plug reinforcing bar, snapping in special tool on card platform 12 stretches, water cement with reinforcement metal straightening and after extending to a certain degree, the casting cement pole.This cement pole intensity height, and cement has further improved the bulk strength of cement pole with the whole parcel of connecting portion.When at the scene cement pole being installed, only need the flange 1 of the end of two bars is matched mutually, and in installing hole 11, install bolt additional and get final product, easy for installation, simple, operating efficiency is improved greatly.Cement rod connecting flange can carry out antirust, preservative treatment when making, reduced processing procedures such as follow-up reparation, maintenance.
