[0002] In construction projects, the key to quality control of post-casting strip construction lies in effectively sealing the edges, preventing concrete from flowing out, and effectively reinforcing the side support formwork to ensure structural stability, thereby ensuring the quality of structural construction at the post-casting strip.

The scaly slurry retaining plate 5 is arranged on the side of the post-cast strip as a side sealing material, and the scaly slurry retaining plate 5 is also a fish scale net. The water stop plate 4 is horizontally arranged between the scaly slurry retaining plates 5. The rigidity of the scaly slurry retaining plate 5 is used to fix it with the water stop plate 4, so as to form a stable and effective side support and sealing system. The middle part of the scaly slurry retaining plate 5 protrudes toward one side of the post-cast strip to form a convex folding portion, which can be embedded in the post-cast strip, thereby increasing the bonding area of ​​the post-cast concrete. A number of folding pieces 7 are arranged on the upper side of the convex folding portion, each of which can be folded toward one side of the post-cast strip to form a steel bar channel, and the steel bars 2 in the post-cast strip pass through the steel bar channel without destroying the scaly slurry retaining plate 5, thereby reducing the steel bar holes on the scaly slurry retaining plate 5 and reducing the risk of leakage. The auxiliary support assembly 3 is supported on one side of the scaly slurry retaining plate 5, and the supporting position of the auxiliary support assembly 3 is adjustable.

[0039] like Figure 2 As shown, in the present embodiment, the convex fold portion includes two connected convex fold honeycomb panels 8, and the two convex fold honeycomb panels 8 are respectively inclined toward one side of the post-casting strip to form a convex fold portion protruding toward one side of the post-casting strip. A plurality of holes are hollowed out on the convex fold honeycomb panels 8, which can effectively increase the surface area of ​​the concrete, enhance the strength of the internal connection of the concrete, improve its overall mechanical properties, and improve the construction quality.

[0040] The folding piece 7 in this embodiment is rectangular, and one side of the folding piece 7 is integrally connected with the scaly slurry guard plate 5. When installing the scaly slurry guard plate 5, the folding piece 7 at the position corresponding to the steel bar 2 is folded toward the side of the post-cast strip so that a steel bar channel is formed at the position of the folding piece 7, and the steel bar 2 passes through the steel bar channel. The operation is simple and convenient; a plurality of convex pieces 6 are provided on the lower side of the convex folded part of the scaly slurry guard plate 5 protruding toward the side of the post-cast strip, and the convex piece 6 and the convex folded part are embedded in the concrete on one side of the post-cast strip, thereby increasing the surface area of ​​the concrete and enhancing the structural stress of the closed concrete connection on both sides of the post-cast strip.

[0041] like Figure 3~4 As shown, the auxiliary support assembly 3 includes a support body, a fixed beam 12, a support rod and a support column 14. The support body is fixedly arranged, and the fixed beam 12 can be installed on the support body in a liftable manner. The support rod is connected to the fixed beam 12 in a horizontally swingable manner, and the support column 14 is vertically and rotatably installed at the end of the support rod. The height supported by the support column 14 can be adjusted by adjusting the fixed beam 12, and the angle supported by the support column 14 can be adjusted by swinging the support rod. The support column 14 is fixedly supported on one side of the scaly slurry retaining plate 5, and a fixing groove 9 is horizontally arranged on the lower side of the scaly slurry retaining plate 5.

The length of the diagonal brace 15 can be adjusted by rotating the diagonal brace adjustment wire tube 27. A fixed beam adjustment slot 23 is vertically opened on the main frame 10. The fixed beam 12 can move up and down along the fixed beam adjustment slot 23. The fixed beam 12 is fixed by a fixing bolt 17.

[0043] like Figures 6 and 7 As shown, two fixed beams 12 are vertically spaced apart, and an adjusting screw 11 is arranged between the two fixed beams 12. The adjusting screw 11 is rotatably connected to any one of the fixed beams 12, and the adjusting screw 11 is threadedly connected to the other fixed beam 12. The distance between the two fixed beams 12 is adjusted by adjusting the screw 11, so that the two fixed beams 12 clamp and fix the support rod, and the support rod is swingably installed between the two fixed beams 12 through the fixing clamp 18.

[0044] Specifically, in the present embodiment, a fixing sleeve 21 is provided on the side of the upper fixing beam 12, and an adjusting wire drum 20 is provided on the side of the lower fixing beam 12. The adjusting wire drum 20 is made of galvanized steel pipe. The adjusting screw 11 rotates through the fixing sleeve 21 and is threadedly connected in the adjusting wire drum 20. Two limit plates 19 are arranged at intervals on the adjusting screw 11. The two limit plates 19 are respectively arranged on the upper and lower sides of the fixing sleeve 21, so that the adjusting screw 11 can only rotate in the fixing sleeve 21 but cannot move up and down. Tighten the fixing bolt 17 of the upper fixing beam 12 to fix it, rotate the adjusting screw 11, and adjust the height of the lower fixing beam 12 until the two fixing beams 12 clamp and fix the support rod.

[0045] like Figure 8 As shown, the support rod is a support screw 16, and the fixing clamp 18 includes two semicircular fixing clips 25. A fixing clip adjustment groove 24 is opened on the opposite side of the two fixing beams 12, and the fixing clip adjustment groove 24 is arranged horizontally. The two fixing clips 25 are respectively slidably installed on the two fixing beams 12 and fixed by fixing clip adjustment bolts 29. Threads are arranged on the inner sides of the two fixing clips 25. The support screw 16 is threadedly installed between the two fixing clips 25. The position and direction of the support screw 16 are determined by adjusting the position and direction of the two fixing clips 25. The two fixing clips 25 are used to clamp the support screw 16 through the two fixing beams 12. The end of the support rod is bent and the bent portion is rotatably connected to the support column 14 through the connecting sleeve 13.

The two fixing clips 18 are respectively arranged on both sides of the fixed beam 12, and the angle between the two supporting rods 16 is adjustable. In this embodiment, the two supporting screws 16 between the upper group of fixed beams 12 are supported on the side of the upper scale-shaped slurry retaining plates 5, and the two supporting screws 16 between the lower group of fixed beams 12 are supported on the side of the lower scale-shaped slurry retaining plates 5. In other embodiments, the number of fixed beams 12 and the number of fixing clips 18 between each group of fixed beams 12 can be adjusted as needed.

[0047] A post-casting strip installation construction process of the present invention uses the above-mentioned post-casting strip installation auxiliary device and includes the following construction steps:

[0048] S1. Determine the location of the exterior wall according to the design drawings, prepare the materials of the steel bars 2, the scaly slurry retaining plate 5 and the auxiliary support assembly 3 according to the design drawings, and produce the scaly slurry retaining plate 5 and the auxiliary support assembly 3 according to the design drawings;

[0050] S3, install and fix the scaly slurry retaining plate 5 at the edge limit position of the post-casting belt, fold the folding piece 7 at the position of the steel bar 2 to ensure that the steel bar 2 passes through, and install and fix the auxiliary support assembly 3 on one side of the scaly slurry retaining plate 5;

[0051] S4, cast concrete 1 on one side at the post-casting strip position, and after the concrete at the post-casting strip position solidifies, remove the auxiliary support assembly 3 and the scale-shaped slurry retaining plate 5, and pull and remove the scale-shaped slurry retaining plate 5 by the support screw 16 and the support column 14 of the auxiliary support assembly 3 and the fixing groove 9;

[0052] S5. After the post-casting joint position reaches the pouring conditions, clean up the debris in the post-casting joint, set up the formwork frame and pour the concrete.

[0053] When the present invention is used, the post-casting strip and the surrounding position are fixed by binding with steel bars 2 in the longitudinal and transverse directions. After the water stop plate 4 is installed and fixed in the middle position, the scale-shaped slurry retaining plate 5 is installed. When installing the scale-shaped slurry retaining plate 5, the folding piece 7 at the position corresponding to the steel bar 2 is folded toward one side of the post-casting strip so that the position of the folding piece 7 forms a steel bar channel, and the steel bar 2 passes through the steel bar channel. The rigidity of the scale-shaped slurry retaining plate 5 is fixedly combined with the water stop plate 4. The height of the fixed beam 12 is adjusted, and the position and angle of the fixing clamp 18 are adjusted to determine the support position of the end of the support screw 16, so that the protrusion on the support column 14 is stuck in the protrusion, and the lower end of the support column 14 is installed in the fixing groove 9 of the scale-shaped slurry retaining plate 5. The cast-in-place concrete 1 is poured on one side of the post-casting strip position.

The installation of the scale-like slurry guard plates 5 on each side is the same as the installation of the scale-like slurry guard plates 5 on one side in the first embodiment. However, in this embodiment, the scale-like slurry guard plates 5 on both sides can use two auxiliary support components 3 respectively, or can share one auxiliary support component 3.

In this embodiment, the connection of the various parts of the auxiliary support assembly 3 is the same as that in the first embodiment. The only difference is that four fixing clips 18 are arranged between the same group of fixed beams 12, that is, four supporting screw rods 16 are fixed between the two fixed beams 12, two of which face the same side, and the other two face the other side. The four supporting screw rods 16 are divided into two groups to respectively support the scale-like slurry retaining plates 5 on both sides.
