2. Holding frame columns shall be set on both sides of entrance doors larger than 1.2m and windows and doors larger than 2m; Or set the constructional column according to the design requirements. According to the design requirements of various regions, the cross section is 10cm× wall width, concrete grade C20, with 2 φ 12 inside, and tie bars 2 φ 6 @ 300 (or set together with masonry tie bars). The bottom of the door bar takes root on the structural plate, and the window column can take root on the windowsill pressure beam. The upper part can be connected with connecting lintels or hinged with structural beams.

3. When the height of the filler wall is more than 4m, set a horizontal tie beam, which is generally located at half height of the wall and should be set in combination with the lintel of doors and windows. The cross-section height of tie beam is generally 18㎝× wall width, concrete label is C20, internal fitting is 4 φ 12, stirrup φ 6 @ 200; Both ends of the longitudinal reinforcement shall be anchored into the concrete column for 35d. The tie beam shall be connected with the structural column, shear wall, constructional column and framed column according to relevant specifications.
