[0025] The present invention will be further described below in conjunction with specific embodiments and drawings.

[0026] Example 1

[0027] refer to Figure 1 , Figure 2 and Figure 3 As shown, a post-cast strip concrete pouring and sealing device includes an upper support rod 1, a sealing mesh 2, a lower support rod 3, an upper sealing strip 4, a lower sealing strip 5 and a node blocking strip 6.

[0028] The upper support rod 1 and the lower support rod 3 are made of steel and are both round tube structures, which can realize the connection and support of the blocking mesh 2. The blocking mesh 2 is made of steel wire and is used to achieve the enclosure of concrete.

[0029] The upper support rod 1 is connected to the upper end of the blocking mesh 2, and the lower end of the blocking mesh 2 is connected to the lower support rod 3. After the upper and lower support rods are fixed, the blocking mesh 2 is fixed, and the tightening effect of the two ends is used to ensure that the blocking mesh 2 is tightened in the middle.

[0030] The upper end of the blocking mesh 2 is wound around the upper support rod 1 and / or the lower end of the blocking mesh 2 is wound around the lower support rod 3, that is, at least one end of the blocking mesh 2 is wound around the support rod, and the blocking mesh is wound around the support rod to shorten or lengthen the mesh, thereby meeting the enclosure height of different upper and lower steel bars. The blocking mesh 2 can also be completely rolled up by the winding effect, which is convenient for transportation and delivery.

[0031] The upper blocking strip 4 and the lower blocking strip 5 are flexible rubber strips and are both rectangular tube structures. Since the upper part of the upper steel bar and the lower part of the lower steel bar still have unenclosed areas, the upper and lower blocking strips are used to block them accordingly to ensure comprehensive enclosure. The blocking strip is also in contact with the blocking mesh 2 wrapped around the support rod, so the grid of the blocking mesh 2 can increase the friction of the blocking strip, further ensuring the stability of the mesh.

[0032] The node blocking bar 6 is used to block the relative position of the end of the pouring plugging device to prevent leakage of slurry from the end gap. The node blocking bar 6 includes a hook part and a flexible strip, one end of the flexible strip is connected to the hook part, the hook part is hung on the upper plugging bar 4, and the flexible strip blocks the gap.

[0033] Example 2

[0034] refer to Figure 1 , Figure 2 and Figure 3 As shown, a post-cast zone concrete pouring and blocking structure includes the pouring and blocking device of Example 1, and also includes steel bars, and the steel bars at the post-cast zone position include upper steel bars and lower steel bars.

[0035] The lower part of the upper steel bar is connected to the upper support rod 1 by wire binding, and the upper part of the lower steel bar is connected to the lower support rod 3 by wire binding. The upper and lower support rods are fixed on the steel bars by wire binding. The enclosure height of the blocking mesh 2 wrapped around the support rod needs to be adjusted in advance to ensure that the actual enclosure height is the same as the enclosure height on site. The blocking mesh 2 is tightly stretched between the upper support rod 1 and the lower support rod 3, and the blocking mesh 2 is used to form a blocking enclosure surface to prevent concrete from flowing outward.

[0036] The upper part of the upper steel bar is connected to the upper blocking strip 4 by wire binding, and the lower part of the lower steel bar is connected to the lower blocking strip 5 by wire binding. The upper blocking strip 4 and the lower blocking strip 5 provide additional enclosure for the upper part of the upper steel bar and the lower part of the lower steel bar. The blocking strip is also in contact with the blocking mesh 2 wound on the support rod, so the grid of the blocking mesh 2 can increase the friction of the blocking strip, further ensuring the stability of the mesh.

[0037] A connection gap node is formed between two adjacent casting and sealing devices, and a node baffle 6 is provided between the connection gap nodes. The hook portion of the node baffle 6 is hung on the upper sealing strip 4, and the flexible strip of the node baffle 6 is blocked at the connection gap node to achieve enclosure and sealing at the opposite ends.

[0038] The workflow of this utility model:

[0039] The first step is to roll the device into a cylindrical shape for easy transportation and handling.

[0040] The second step is to tie the upper and lower steel mesh at the post-cast joint.

[0041] The third step is to place the device inside the upper and lower layers of steel mesh where the post-cast strip needs to be sealed.

[0042] Step 4: Wrap the wire mesh around the support rod of the rotating device and adjust the height of the sealing device according to the actual height of the sealing surface.

[0043] Step 5: Use wire to tie the upper support rod of the device to the upper steel mesh.

[0044] Step 6: Use wire to tie the lower support rod of the device to the lower steel mesh.

[0045] Step 7. Tie and connect the upper sealing strip to the upper steel mesh to seal the upper protective layer of the upper steel mesh.

[0046] Step 8. Tie and connect the lower sealing strip to the lower steel mesh to seal the lower protective layer of the lower steel mesh.

[0047] Step 9. Adjust the position of the device to ensure that a sealing surface is formed at the boundary of the post-cast strip, and install node retaining strips at the opposite ends.

[0048] Step 10: Pour concrete and use a sealing device to prevent the concrete from flowing to the post-cast zone.

[0049] Step 11. After the post-cast strip reaches the required settlement time, the sealing device will be chiseled out and the boundary will be roughened. Concrete will be poured at the post-cast strip to form a whole with the two side parts.

[0050] The above basic examples and further optional examples of the utility model can be freely combined to form multiple embodiments, which are all embodiments that can be adopted and claimed for protection by the utility model. In the scheme of the utility model, each optional example can be arbitrarily combined with any other basic examples and optional examples.
