桥梁充气芯模的性能、特征 
1、桥梁充气芯模设计科学合理 
 
　应用橡胶充气芯模，予制或现场浇筑出来的成品构件，都能满足设计要求，且操作简单省工、省时，省材。                                                                                                                                                                                        2、桥梁充气芯模有良好的耐老化性能，使用寿命长    本产品用合成橡胶、天然橡胶与加强层硫化后制成。既有很好的搞胀强度，又有弹性和柔韧性，所以能满足在各种工作条件使用。                                                                                                                                                              

  3、桥梁充气芯模适用温度广泛在-10%～+90%的范围内，材质没有变化。                                                         

   4、桥梁充气芯模为建筑现场施工轻型化提供了有利条件予应力空心混凝土构件，由于采用橡胶芯模，其重量比非予应力实心构件轻20%，因此减轻建筑物上部结构的重量，可以使桩基缩短，跨径增大，现场施工简便安全。                                                                                                                                                                                        5、桥梁充气芯模施工工艺简便、安全、卫生使用橡胶芯模，只用少量简单工具，无需特殊工艺。只要将芯模入负盘笼内，充气压力达到工作压力时，即浇筑混凝土，待混凝土初凝时，将芯模放气抽出，即可完成成品构件的成型，不污染环境。                                                                                                                                                            

  常用桥梁橡胶芯模的规格尺                                                                                                                                               

   常用规格常用异型规格（一体） φ120（φ150）mmX6～20m φ350（φ360）mmX10～40m 350X530(540)mmX10～40m φ180mm X６～20m φ400mm X10～40m 350X530(540)mmX10～40m φ200（φ220）mmX8～20m φ500mm X10～40m 350(360)X560mmX10～40m φ240（φ250）mmX8～20m φ600mm X10～40m 350X560(570)mmX10～40m φ260mm　X8～20m φ700mm X10～40m 360X640(650)mmX10～40m φ300（φ330）mmX15～40m φ800～1000mm X10～40m 360X540(550)mmX10～40m                                                                                                                                                                                                      桥梁充气芯模使用规范：                                                                                                                                                   

  1、入模将芯模牵引到钢筋笼内，并使纵向 接缝朝上                                                                                                    

 2、充气                                                                                                                                                                               （1）打开阀门充气到规定压力，即可关闭阀门                                                                                                                   

 （2）异型芯模应交替充气直到达到规定压力。                                                                                                         

 （3）使用压力。                                                                                                                                                               

  3、桥梁充气芯模固定                                                                                                                                                     

 （1）因振捣混凝土时，芯模会向上浮，所以必须将上、下、左、右都加以固定，另外加上压块克服上浮力。                                                                                                                                                                                           （2）一般 φ250mm芯模箍筋间距为80cm。如直径加大则箍筋间距相应减小。                                                                                                                                                                                          4、桥梁充气芯模浇筑混凝土                                                                                                                                            

 （1）浇筑混凝土的工艺与实心构造件基本相同。                                                                                                                                                                                    （2）使用高频插入式振捣棒从两侧同时振捣，可防止芯模左右移动                                                                                                                                                                                         （3）振捣棒端头不可接触芯模，以免穿破发生漏气。                                                                                                                                                                                           5、桥梁充气芯模拆模                                                                                                                                                               

 待混凝土初凝后，即将芯模抽出脱模。（打开阀门放气、脱模时间根据施工情况自定）                                                                                                                                                                                          使用压力示意表                                                                                                                                                                     

   直径（mm) 使用压力 (MPa) 80 0.12 120 0.10 150 0.08 200 0.07 250 0.05 400 0.04 500 0.035 600 0.03 700 0.027 800 0.026 900 0.025 2200 0.005
