Its structure is relatively complex and has many splicing links. It takes a day to install the wall frame and the inner support frame alone. In addition, the weight of each piece is large and requires the help of a hand chain hoist. In the case of a small space, it is inconvenient to operate. Affected by the diagonal bracing rods of the standard section, the installation position of the wall frame on the standard section is limited, and the requirements for the attachment point of the on-site building are relatively high.

[0006] Preferably, the cross brace includes a longitudinal brace and two transverse braces detachably mounted on the longitudinal brace, and the axes of the two transverse braces are located on the same straight line and perpendicular to the axis of the longitudinal brace, and the adjacent ends of the two transverse braces are detachably mounted on the longitudinal brace via a connecting plate and a screw.

[0007] Preferably, at least one end of at least one transverse strut and / or longitudinal strut is detachably connected to an adjusting screw rod with adjustable length, and the adjusting screw rod is detachably connected to an end plate via a connecting rod.

[0008] Preferably, the connecting rod, the transverse support rod and the longitudinal support rod are also equipped with a screw sleeve at one end adjacent to the adjusting screw rod, and the two ends of the adjusting screw rod are respectively screwed into the screw sleeve and covered with a fastening nut for preventing the adjusting screw rod from rotating.

[0009] Preferably, the middle portion of the adjusting screw rod also has an adjusting hole for rotating the adjusting screw rod.

[0010] Preferably, the wedge block structure includes a wedge block and a connecting block that are fixedly connected to each other, and one side of the end plate is formed with an inclined surface facing the inner wall of the main chord of the standard section, the two side surfaces of the wedge block are respectively abutted against the inclined surface of the end plate and the inner wall of the main chord of the standard section, and the end of the connecting block facing away from the wedge block is detachably fixed to the end plate by a fastener.
