[0002] Secondary lining is cast concrete or reinforced concrete lining constructed inside the primary support during tunnel construction, and together with the primary support, it forms a composite primary lining. Compared with primary support, secondary lining refers to the inner lining constructed with concrete and other materials after the tunnel has been initially supported, in order to strengthen support, optimize route drainage system, beautify appearance, and facilitate the installation of communication, lighting, monitoring and other facilities, so as to meet the requirements of modern highway tunnel construction.

[0003] The connection firmness between the plates of the secondary lining formwork affects the construction quality of the secondary lining. Therefore, a fixed snap-on joint structure between the plates of the tunnel secondary lining formwork is needed, which can improve the connection firmness between the plates.

[0007] The fastener comprises a screw and a nut, and the screw is rotatably connected to two oppositely arranged fixing ears on the second plate through a rotating shaft.

[0008] A screw placement groove is provided at the front end of the fixing buckle, and the first plate and the second plate are fixed by placing the screw in the screw placement groove and locking it with the nut.

[0009] The rear end of the fixing buckle is rotatably connected to two oppositely arranged fixing ears on the first plate through a rotating shaft.

[0010] The convex block is wrapped with a rubber layer.

[0011] The utility model has the advantages of simple structure and convenient operation; the panels are connected and fixed by fixing buckles to ensure that the joints of the panels are firmly fixed. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 2 It is a structural schematic diagram of the fixing buckle of the utility model. DETAILED DESCRIPTION

[0014] The following is a further detailed description of the features of the present invention and other related features through embodiments in conjunction with the accompanying drawings to facilitate understanding by technicians in the same industry:

[0015] like Figure 1~2 As shown, the marks in the figure represent respectively:

[0016] The first plate 1, the second plate 2, the fixing buckle 3, the groove 4, the protrusion 5, the screw 6, the nut 7, the first rotating shaft 8, the first fixing ear 9, the screw placement groove 10, the second rotating shaft 11, the second fixing ear 12, and the joint 13.

[0017] Example: Figure 1~2 As shown, this embodiment relates to a fixed buckle joint structure between the plates of the secondary lining template of the tunnel, mainly including a first plate 1, a second plate 2 and a fixed buckle 3, a joint 13 is formed between the first plate 1 and the second plate 2, and the fixed buckle 3 is used to fix the first plate 1 and the second plate 2. The ends of the first plate 1 and the second plate 2 are both provided with notches, and the notches of the first plate 1 and the second plate 2 are combined into a groove 4. The rear end of the fixed buckle 3 is rotatably connected to the first plate 1, and the front end is fixed to the second plate 2 through a fastener. The fixed buckle 3 is provided with a protrusion 5, and the size and shape of the protrusion 5 correspond to the size and shape of the groove 4 respectively. The cooperation between the protrusion 5 and the groove 4 ensures that the plate joint is firmly fixed. In addition, the protrusion 5 is wrapped with a rubber layer to play a buffering and sealing role.

[0018] like Figure 1~2As shown, the rear end of the fixing buckle 3 is rotatably connected to two oppositely arranged first fixing ears 9 on the first plate 1 through the first rotating shaft 8, so that the rear end of the fixing buckle 3 can be rotated. The fastener includes a screw 6 and a nut 7. The screw 6 cooperates with the nut 7. The screw 6 is rotatably connected to two oppositely arranged second fixing ears 12 on the second plate 2 through the second rotating shaft 11, so that the screw 6 can be rotated. A screw placement groove 10 is provided at the front end of the fixing buckle 3. The screw placement groove 10 is an elongated hole and the innermost shape of the screw placement groove 10 is semicircular, corresponding to the shape of the screw 6. The screw 6 is placed at the innermost side of the screw placement groove 10 and locked with the nut 7 to fix the first plate 1 and the second plate 2.

[0019] The beneficial technical effects of this embodiment are: simple structure and easy operation; the panels are connected and fixed by fixing buckles to ensure that the joints of the panels are firmly fixed.

[0020] Although the above embodiments have described the concepts and embodiments of the purpose of the utility model in detail with reference to the accompanying drawings, ordinary technicians in this field can recognize that various improvements and modifications can still be made to the utility model without departing from the scope of the claims, so they are not described one by one here.
