  YI、FUJIAZHIDIANJIAGUFANGFA

  I. reinforcement method of additional fulcrum

百盛彩票开户  ZAILIANG、BANZHONGJIARUYIGEZHIDIAN,JIANXIAOKUADU,CONGERTIGAOQICHENGZAINENGLI,BINGNENGJIANSHAOHEXIANZHILIANG、BANDEWANQUBIANXING。ZHEIZHONGFANGFASHIYONGYUZHUFANGDEMUDESHIMINGQUEMEIYOUXIANZHIDEDAKUADUJIEGOULIANG,BAN,HENGJIA,SHUIPINGJIEGOU、WANGJIADENGJIAQIANGQIYOUDIANSHIJIANDAN、KEKAO,QUEDIANSHISHIYONGKONGJIANHUISHOUDAOYIDINGDEYINGXIANG。

百盛彩票开户  Adding a fulcrum in the beam and slab can reduce the span, improve the bearing capacity, and reduce and limit the bending deformation of the beam and slab. The purpose of this method for housing is to make clear that the advantages of this method are simple and reliable, while the disadvantages are that the use space will be affected to some extent.

  Sticking and strengthening steel structure

  ZHEIZHONGJIAGUFANGFASHILIYONGZHANJIEJIZHANZAIGANGJIEGOUSUNSHANGBUFENDEBIAOMIAN,SHIYIBUFENHEZAITONGGUOZHANJIECENGZHUANYIDAOBIAOMIAN,CONGERJIANGDIJIEGOUSUNSHANGBUFENDEYINGLI。YUQITAJIAGUFANGFAXIANGBI,JUYOUMINGXIANDEYOUDIAN:

  This reinforcement method is to use the adhesive to stick on the surface of the damaged part of the steel structure, so that part of the load is transferred to the surface through the bonding layer, so as to reduce the stress of the damaged part of the structure. Compared with other reinforcement methods, it has obvious advantages:

百盛彩票开户  (1)BIQIANGDUHEGANGDUGAO,JIAGUHOUJIBENBUZENGJIAYUANJIEGOUZIZHONGHEYUANGOUJIANCHICUN;

百盛彩票开户  (1) it has high specific strength and rigidity, and the original structure weight and original component size are not increased basically after reinforcement;

  (2)FUHECAILIAOJUYOULIANGHAODEKANGPILAO、NAIFUSHIXINGNENG;

百盛彩票开户  (2) the composite material has good fatigue resistance and corrosion resistance;

百盛彩票开户  (3)CAOZUOFANGBIAN,CHENGBENDI,XIAOLVGAO,KEZAIXIAOKONGJIANNEISHIGONG,TEBIESHIHEXIANCHANGWEIXIU。

  (3) convenient operation, low cost and high efficiency, it can be constructed in a small space, especially suitable for on-site maintenance.

  (1) add supports to form spatial structure, and check and calculate according to spatial structure. The bearing capacity and dynamic characteristics of the structure can be improved by increasing the support to increase the structural stiffness or adjusting the natural frequency of the structure;

百盛彩票开户  (2)ZENGJIAZHICHENGHUOFUZHUGAN,JIANGDIJIEGOUZHANGXIBI,TIGAOJIEGOUWENDINGXING;

  (2) increase the support or auxiliary rod, reduce the slenderness ratio of the structure and improve the stability of the structure;

  (3) in bent structure, the rigidity of columns should be strengthened to bear most of the horizontal force, so as to reduce the load of other columns.

  Technical method of prestressed steel structure reinforcement

百盛彩票开户  GANGJIEGOUYUYINGLIJIAGUFANGFABAOKUOZHIJIEZHANTIEFAHEZHENGTIJIAGUFA。ZHANTIEFASHIZHIJIEZAILIANGDUANMAOGUHEYUYINGLIHOU,TONGGUOZHANTIEZAIGANGJIEGOUBIAOMIANHEGOUJIANBIAOMIANDEYIBANYONGTUSHIBIANGANG,DUIGOUJIANHUOQIJUBUJINXINGJIAGU。ZHENGTIJIAGUFASHIJIANGYUYINGLIMAOSUODEYINGLIJINXINGBANGZHADIAOZHENG,SHIYONGYUZHENGTIJIEGOUDEJIAGU。

  The methods of prestressed reinforcement of steel structure include direct bonding method and integral reinforcement method. After anchoring and prestressing directly at both ends, the general purpose of pasting on the surface of steel structure and component is flat steel, which can reinforce the component or its part. The integral reinforcement method is to adjust the stress of prestressed anchor cable by binding, which is suitable for the reinforcement of integral structure.

百盛彩票开户  Advantages of prestressed reinforcement technology:

  (1)JIAGUGONGZUOKEYIBUXIEBUTINGJINXING;

百盛彩票开户  (1) the reinforcement work can be carried out continuously;

  (2)SHIJIAYUYINGLIKEYIZHIJIEJIANSHAOBIANXING,KUAISUXIAOCHUDUOYUYINGLIHEFENGZHINEILI;

百盛彩票开户  (2) prestressing can directly reduce the deformation and quickly eliminate the redundant stress and peak internal force;

  (3)KEYIXIAOCHUYINGLIZHIHOUXIANXIANG,CHONGFENLIYONGGAOQIANGDUTEXING,TIGAOJIAGUXIAOLV。

  (3) it can eliminate the phenomenon of stress lag, make full use of the high-strength characteristics and improve the reinforcement efficiency.

  (4)KEJIANGDIZHANJIEJIEMIANBOLIYINGLI,BIMIANZHENGTIBOLI,TIGAOJIAGUKEKAOXING;

  (4) it can reduce the peeling stress of bonding interface, avoid the whole peeling and improve the reliability of reinforcement;

  (5)JIANGDIJIAGUCHENGBENHESHIYONGCHENGBEN。

百盛彩票开户  (5) reduce the cost of reinforcement and use.
