1. Assembly and combination of building formwork. The joint between the formwork and the formwork is connected by the steel clad wood with two holes. The steel clad wood with two holes has the advantages of small usage, standard size, high flatness, high strength, long service life, etc. The formwork shall be assembled after the completion of formwork assembly. Penetrate the through wall bolt according to the designed hole position.

2. Install the main keel of the wall in turn. First, install the second row of keels from the ground. Fix the cross gasket nuts preliminarily. Insert the steel secondary keels in turn with a spacing of 200mm~250mm. Install the main keels at the upper and lower parts in turn.

3. For installation at internal corners, fix the internal corners at the connection corners of the main keel, connect and lock the main keel at the internal corners, and install pins to fix and lock the connection between the internal corners and the main keel so that it reaches 90 degrees horizontally and vertically, so as to achieve a more stable effect without mortar leakage and mold expansion.

4. The installation of wall main keel connectors is used to connect the splicing between two main keels and fix the connection with pins. Combined with the application of the main keel of the wall in the actual structure, the connector can have a small size adjustment function, with the size adjustment range of 0~150mm. The main keel of the wall is suitable for walls with long and short formwork structures.

5. The door and window openings and openings are reinforced with hook bolts in combination with the main keel of the wall. The installation speed is fast and the operation is simple. Its major advantage is that when encountering wall to column joints in the external wall structure of large underground garages, this component can be easily solved, and the installation is convenient and stable.

6. For the reinforcement of external corners, external corner hooks can be used for fixing and locking. In this process, 2cm-3cm spacing shall be reserved for the butt joint of the main keel of the wall at the external corners. The external corner hooks can be used for fastening and secondary locking. In addition, the external corners can be fixed and locked by inserting pins to ensure that the external corner walls reach 90 degrees horizontally, without mortar bleeding and mold expansion, and have a more stable effect.
