[0022] The disassembly mechanism 4 includes an extension plate 401, a cross plate 402, an insertion block 403 and a limit plate 404. The extension plate 401 is movably installed on the top of the baffle 2, the cross plate 402 is fixedly installed on the top of the extension plate 401, the insertion block 403 is fixedly installed on the bottom of the cross plate 402, and the limit plate 404 is installed on the top of the bottom plate 1.

[0023] In Figure 1 and Figure 2 , by setting the disassembly mechanism 4, the structures of the disassembly mechanism 4 cooperate with each other to quickly fix the support plate 3, which better saves manpower. The disassembly mechanism 4 includes an extension plate 401, a cross plate 402, an insertion block 403 and a limit plate 404. A card slot is opened inside the baffle 2, and a card block 5 is fixedly installed at the bottom of the extension plate 401. The number of the card blocks 5 is two. By setting the extension plate 401, the card block 5 at the bottom is inserted into the card slot and the extension plate 401 can be fixed stably through a fixing screw.

[0024] In Figure 1 and Figure 2 , one side of the two card blocks 5 away from the extension plate 401 extends into the two card slots respectively. The number of the support plates 3 is four, and the insertion block 402 will enter the card slot 6 to fix the top of the support plate 3.

[0025] In Figure 1 and Figure 3 , slots 6 are opened on the tops of all four support plates 3. The number of the insertion blocks 403 is four, and the four insertion blocks 403 are equidistantly distributed.

[0026] In Figure 2 and Figure 3 , one side of the four insertion blocks 403 away from the cross plate 402 extends into the four slots 6 respectively. A positioning plate 7 is fixedly installed on the side of the limit plate 404 close to the support plate 3. By setting the limit plate 404, the front sides of the four support plates 3 are further fixed. At this time, the positioning block 8 will be inserted into the positioning groove.

[0027] In Figure 2 and Figure 3 , one side of the positioning plate 7 away from the limit plate 404 extends between the two support plates 3, and positioning blocks 8 are fixedly installed on the front sides of all four support plates 3.

[0028] In Figure 2 and Figure 4Among them, a positioning groove is provided on the rear side of the limit plate 404. One side of the positioning block 8 away from the support plate 3 extends into the positioning groove. The baffle 2 and the extension plate 401 are in threaded connection. The positioning plate 7 and the support plate 3 are in threaded connection. The positioning plate 7 is respectively inserted into the intervals of the support plates 3. Finally, the two sides of the positioning plate 7 can be further locked by fastening bolts to further fix the support plate 3.

[0029] In summary, for the temporary support used in the cantilever casting of the continuous beam of the special large bridge, by setting the extension plate 401, the clamping block 5 at the bottom is inserted into the clamping groove and the extension plate 401 can be stably fixed by fixing screws. At this time, the insertion block 402 at the top will enter the clamping groove 6 to fix the top of the support plate 3. By setting the limit plate 404 to further fix the front sides of the four support plates 3, at this time, the positioning block 8 will be inserted into the positioning groove, and at the same time, the positioning plate 7 is respectively inserted into the intervals of the support plates 3. Finally, the two sides of the positioning plate 7 can be further locked by fastening bolts to further fix the support plate 3, solving the problem that a large number of screws are used in the actual assembly process of the device, which causes the operator to consume a large amount of time both in the installation and disassembly processes, not only consuming manpower but also having low efficiency.

[0030] Moreover, during use, first, one end of the four support plates 3 is attached to the inner wall of the baffle 2, and then the limit plate 404 is attached to the front sides of the four support plates 3. At this time, the four positioning blocks 8 respectively enter the four positioning grooves, and at the same time, the positioning plates 7 are respectively inserted into the intervals of the support plates 3. The two sides of the positioning plate 7 and the two sides of the support plate 3 are locked by two expansion screws. Then, the clamping block 5 is snapped into the clamping groove, and the extension plate 402 and the baffle 2 are stably fixed by fastening bolts. Finally, the insertion block 403 on the cross plate 402 will enter the insertion slot 6 to further fix the support plate 3, so as to achieve the purpose of solving the problem that a large number of screws are used in the actual assembly process of the device, which causes the operator to consume a large amount of time both in the installation and disassembly processes, not only consuming manpower but also having low efficiency.
