干式外包型钢加固法时把型钢直接外包于原柱，与原柱间没有粘结，或虽填塞有

Dry outer steel reinforcement for the beam directly upon the original outer column, and no adhesion between the original column, packed with cement or mortar, although there is no guarantee of shear reinforcement incorporated methods effective transfer surface. <br>Wet encased steel reinforcement method is left between the steel columns spaced original, and latex caulking or grout or epoxy mortar fine aggregate concrete poured therebetween, both integrally bonded to a reinforcement method.

Dry-type outsourced steel reinforcement method directly outofs the original column, and the original column is not bonded, or although filled with cement mortar but can not guarantee the effective transfer of the combined surface shear force reinforcement method. Wet outsourced steel reinforcement method is to leave a certain interval between the type steel and the original column, and in between filled with milk glue mud or epoxy mortar or watering fine stone concrete, the two stick together into a one-piece reinforcement method.

In the dry enclosed section steel reinforcement method, the section steel is directly enclosed in the original column, and there is no bond between the original column, or although the cement mortar is stuffed, it can not guarantee the effective transfer of shear force on the joint surface.<br>The wet enclosed section steel reinforcement method is a kind of reinforcement method that leaves a certain distance between the section steel and the original column, and fills in latex cement slurry or epoxy mortar or pours fine stone concrete between them, and binds the two into one.<br>
