[0018] Please refer to Figures 1-2 In the embodiments of the utility model, a splicing connecting piece of a concrete wood formwork comprises four groups of pipe assemblies in a meandering distribution, one group of pipe assemblies comprises two clamping pipes 1, and a connecting block 2 is welded between the two clamping pipes 1 in one group of pipe assemblies.

[0019] The two groups of pipe assemblies in a symmetric distribution are connected through a connecting mechanism, and the connecting mechanism is used for fixing the pipe assemblies to the outside of the wood formwork.

[0020] The elastic mechanism is distributed at the two ends of the connecting mechanism and is used for pre-fixing the two groups of symmetric pipe assemblies to the outside of the wood formwork.

[0021] In the embodiment, first, when pouring the concrete column, the wooden cushion plate is fixed on the ground by bolts, then the wooden formwork is fixed on the wooden cushion plate by bolts, after the wooden formwork is spliced, the four groups of pipe assemblies are symmetrically arranged, after the two groups of pipe assemblies are symmetrically arranged and the wooden formwork is attached, the connecting mechanism is pulled, the elastic mechanism is stretched, the two connecting mechanisms are expanded outward, then the connecting mechanism is aligned with the outer wall of one end of the pipe assembly, after alignment, the force applied to the connecting mechanism is removed, the connecting mechanism is pressed on the outer wall of one end of the pipe assembly, and the elastic mechanism is in an incomplete reset state, so that the elastic mechanism applies a pulling force to the pipe assembly through the connecting mechanism, so that the pipe assembly is pre-connected to the outer side of the wooden formwork, after pre-connection, the pipe assembly is kept in a relatively stable state without supporting, and finally the nut 9 is tightened.

[0022] Please refer to Figure 1 and Figure 2 The connecting mechanism comprises limiting blocks 3 clamped on the outer sides of the two ends of the clamping pipe 1, the limiting blocks 3 are integrally formed with protruding heads 4 protruding outward on the outer sides away from the clamping pipe 1, the connecting mechanism further comprises a through hole formed in the limiting blocks 3 and the protruding heads 4, and a plug-in rod 5 is inserted into the inner wall of the through hole.

[0023] In the embodiment, the two groups of pipe assemblies are symmetrically arranged on the outer side of the wooden formwork, at this time, two workers are needed to operate to make the two symmetric pipe assemblies at the same height, then the two workers pull the two limiting blocks 3 on the outer wall of the plug-in rod 5 respectively, the two limiting blocks 3 move in opposite directions, at this time, the elastic mechanism is stretched, then the plug-in rod 5 is translated along the length direction of the symmetrically distributed pipe assembly, the plug-in rod 5 is clamped between the two clamping pipes 1, then the force applied to the limiting blocks 3 is removed, at this time, the elastic mechanism is reset, and the limiting blocks 3 are clamped to the outer wall of the clamping pipe 1, after the two ends of the two groups of pipe assemblies are limited, the pipe assemblies are pre-fixed to the outer side of the wooden formwork.
