The fixing mechanism comprises a screw rod 10, a hook rod, a sleeve 11, a plug 9 and a fixing piece 3. The screw rod 10 passes through two sides of a formwork through a hole 2 of the formwork. The sleeve 11 is sleeved on the outer contour of the screw rod 10 and can be expanded in the radial direction. The sleeve 11 is coaxially sleeved on the outer side of the screw rod 10. After the sleeve 11 passes through the hole 2 of the formwork, the sleeve 11 can be driven to expand so that the axial ends of the sleeve 11 are tightly abutted against the inner sides of the two formworks. The screw rod 10 can slide in the axial direction relative to the sleeve 11. The hook rod is arranged on the screw rod 10 in the axial sliding mode. The hook rod is provided with a hook part. The hook part is arranged on the hook rod in the rotating mode through an elastic piece 1. The elastic piece 1 drives the hook part and the hook rod to form an acute angle. After the sleeve 11 is expanded, the hook rod passes through the hole 2 and is located in the sleeve 11 so that the hook part is used for tightly abutting against the inner side of the formwork. The fixing piece 3 is arranged on the screw rod 10 and is used for tightly abutting against the outer side of the formwork. The plug 9 is used for plugging the hole 2 of the formwork. The plug 9 is provided with a through hole for the rod part to pass through. The installation mechanism comprises a shell 6, a driver 1, a sleeve 14 and a push plate 1.

The push plate 1 is used for being connected with the hook rod. The device can effectively solve the installation and fixing of the form bar. The fixing mechanism forms a double-F buckle stress in the formwork support so that the stress on the inner and outer sides can be borne. The formwork system is more stable. The installation mechanism is very convenient for fixing the fixing mechanism and saves manpower.

[0029] In the embodiment, the device is used for supporting and fixing the integrated thermal insulation formwork. The integrated thermal insulation formwork has three processes of formwork, thermal insulation and plastering. The three processes are changed into one process by using the material. The integrated thermal insulation formwork is used as the outer wall formwork and is poured with the concrete to form the integrated construction of the formwork, the thermal insulation and the plastering.

[0030] The holes 2 are arranged on the formwork in an array. Each screw rod 10 passes through two sides of two formworks. The screw rod 10 is used for connecting the two formworks as a bearing base.

The sleeve body 111 is arranged on the outer side of the gas bag part 112. The gas bag part 112 can be inflated to expand the sleeve body 111 in the radial direction of the screw rod 10.

[0032] In the embodiment, the sleeve body 111 comprises a fixed part and a sliding part, which are circumferentially closed to form a ring. The sliding part is slidingly arranged in the fixed part. After the air bag part 112 is inflated, the sliding part slides out of the fixed part, so that the overall size of the sleeve body 111 is increased. The plug 9 is provided with a protruding part 91, which is matched with the diameter of the hole 2. The plug 9 and the protruding part 91 have an inflation channel. When the plug 9 is tightly arranged on the outside of the formwork, the protruding part 91 extends into the hole 2, and the inflation channel is communicated with the air bag part 112. The inflation channel of the plug 9 is provided with a blocking member, which is used to block the inflation channel, so as to effectively prevent the gas from escaping from the inflation channel of the plug 9.

When the coil spring expands, the connecting rope contracts, so that the rod part moves towards the mounting part 7.

[0037] In the embodiment, the elastic member one 4 is a torsion spring. In the absence of external force, the torsion spring is used to drive the included angle between the hook part and the rod part to form an acute angle. When the hook rod is taken out, a large outward force is applied to drive the torsion spring to be in a stretched state. When the two are horizontal, the hook rod 1 can be taken out, the formwork is fixed, and the hook rod 1 can be used again.
