Modular fiber cement board mounting keel frame

The utility model relates to the technical field of fiber cement board installation, in particular to a modular fiber cement board installation keel frame, and solves the problem that in the prior art, a modular fiber cement board needs to be fixed with much time. The problem that the construction efficiency of personnel is negatively affected due to the fact that the working efficiency is reduced due to long-time operation of the personnel when the personnel install multiple groups of modular fiber cement boards is solved. A modular fiber cement board mounting keel frame comprises a keel frame outer frame, a fiber cement board is detachably connected to an inner cavity of the keel frame outer frame, and mounting grooves are formed in the peripheral surface wall of the keel frame outer frame. According to the installation structure, connection between the fiber cement board and the keel frame outer frame is more concise, personnel can control the use number of the installation structure according to actual us
