Therefore, manual watering and curing are generally adopted, but it is difficult to ensure the curing coverage area, the curing time cannot be guaranteed, and the maintenance quality of the cast-in-situ beam-columns cannot be guaranteed.

[0003] After retrieval, a Chinese patent discloses a concrete beam-column moisture preservation and curing tool (authorized announcement number CN211007724U), which includes a moisture preservation layer, a waterproof layer is thermoplastically formed outside the moisture preservation layer, and an airbag is fixed outside the waterproof layer; the moisture preservation layer, the waterproof layer, and the airbag form a curing moisture preservation film, and sticky tapes are provided at both ends of the curing moisture preservation film, and the curing moisture preservation film is fixed on the concrete beam-column through the sticky tapes. Although this patented technology can improve the moisture preservation and curing quality of concrete beam-columns and reduce the labor intensity, during the curing process of the existing concrete beam-columns, it is necessary to soak the curing moisture preservation film and then use male and female tapes to fasten and fix the curing moisture preservation film. When the curing moisture preservation film is soaked, its weight will increase greatly, which is likely to cause the male and female tapes to come off, and it cannot play the role of moisture preservation and curing for the concrete beam-columns. At the same time, in the prior art, by inflating the airbag, the inflated airbag drives the curing moisture preservation film to fit with the concrete beam-column, but the exposed airbag is easily scratched by sharp stones and other objects in the construction environment, so the moisture preservation effect on the concrete beam-column cannot be guaranteed, and the service life of the airbag is greatly reduced.

[0030] As Figures 1-4 shown, it includes a concrete beam-column main body 18. A first arc-shaped plate 1 and a second arc-shaped plate 14 are arranged on the outer side of the concrete beam-column main body 18. The first arc-shaped plate 1 and the second arc-shaped plate 14 are connected by a hinge. Clamping mechanisms are arranged inside both the first arc-shaped plate 1 and the second arc-shaped plate 14, and a moisturizing and protecting mechanism is arranged at the bottom of the first arc-shaped plate 1 and the second arc-shaped plate 14;

[0031] The clamping mechanism includes four threaded rods 3 threadedly connected inside the first arc-shaped plate 1 and the second arc-shaped plate 14. Arc-shaped clamping plates 5 are rotatably connected to the adjacent ends of two threaded rods 3;

[0032] The moisture - retaining and protective mechanism includes an annular plate 9 arranged at the bottom ends of the first arc - shaped plate 1 and the second arc - shaped plate 14. The annular plate 9 is divided into two sections and connected by a hinge. Two arc - shaped air bags 13 are fixedly connected to the inner wall of the annular plate 9, and corrugated pipes 11 are bonded to the outer sides of the arc - shaped air bags 13.

[0033] Through the coordinated use of the first arc - shaped plate 1 and the second arc - shaped plate 14, it can play an important supporting role for the clamping mechanism and the moisture - retaining and protective mechanism. And through the action of the clamping mechanism, it can clamp the concrete beam - column body 18, and during the clamping process, it is convenient to install the moisture - retaining and protective mechanism.

[0034] As Figure 1 and Figure 2 shown, the clamping mechanism further includes two sliding plates 4 fixedly connected to the outer sides of the arc - shaped clamping plates 5. The two sliding plates 4 are respectively arranged on both sides of the threaded rod 3. Fixed plates 2 are arranged on the outer sides of both the first arc - shaped plate 1 and the second arc - shaped plate 14. The sides of the sliding plates 4 away from the arc - shaped clamping plates 5 are fixedly connected to the corresponding fixed plates 2, and the sliding plates 4 are all slidably connected to the interiors of the first arc - shaped plate 1 and the second arc - shaped plate 14.

[0035] When it is necessary to clamp the concrete beam - column body 18, the threaded rod 3 can be rotated to drive the corresponding arc - shaped clamping plates 5 to gather towards the middle. And through the arrangement of the sliding plates 4, a limiting effect is exerted on the arc - shaped clamping plates 5, so that the arc - shaped clamping plates 5 move horizontally under the drive of the threaded rod 3. Furthermore, it can drive the four arc - shaped clamping plates 5 to clamp the concrete beam - column body 18, making the moisture - retaining and protective mechanism at the bottom ends of the first arc - shaped plate 1 and the second arc - shaped plate 14 more stable, and at the same time facilitating the long - term moisture - retaining maintenance operation of the concrete beam - column body 18.

[0036] As Figure 3 shown, the moisture - retaining and protective mechanism further includes clamping strips 6 fixedly connected to both ends of the bottom of the fixed plate 2.

Furthermore, it can drive the fixed plate 2 to move. At the same time, it can drive the clamping strips 6 at the bottom end of the fixed plate 2 to extend into the interior of the arc - shaped grooves 8 and be clamped with the corresponding clamping grooves 10, thereby enabling the rapid installation operation of the annular plate 9.

[0039] Through the arrangement of the arc-shaped airbag 13, the arc-shaped airbag 13 with volume expansion can be used to push the arc-shaped moisture preservation layer 12 into close contact with the surface of the concrete beam-column body 18, so as to improve the moisture preservation effect of the arc-shaped moisture preservation layer 12 on the concrete beam-column body 18.

[0040] As Figure 3 shown in the figure, two air inlet pipes 19 are arranged on the outer side of the corrugated pipe 11. One end of each air inlet pipe 19 penetrates through the corrugated pipe 11 and extends into the corresponding arc-shaped airbag 13, and a plug 15 is arranged at the end of each air inlet pipe 19 away from the corrugated pipe 11.

[0041] Through the arrangement of the corrugated pipe 11, an important protective effect can be achieved on the arc-shaped airbag 13, reducing scratches on the arc-shaped airbag 13 caused by external sharp objects, thereby improving the service life of the arc-shaped airbag 13. By inflating the air inlet pipe 19, the arc-shaped airbag 13 can expand in volume, and the air inlet pipe 19 is blocked by the plug 15 to prevent the arc-shaped airbag 13 from leaking air.

Second fixing blocks 17 are fixedly connected to the outer sides of the opening and closing parts of the annular plate 9, and the two second fixing blocks 17 are connected by bolts.

[0043] By installing the two first fixing blocks 7, the first arc-shaped plate 1 and the second arc-shaped plate 14 can be fixed, making the clamping of the concrete beam-column body 18 more stable. By installing the second fixing blocks 17, the two ends of the annular plate 9 can be fixed, and at the same time, it is convenient to disassemble the annular plate 9, so as to facilitate secondary utilization.

[0044] As Figure 4 shown in the figure, a circular groove 16 matching the threaded rod 3 is opened in the fixing plate 2, and the arc-shaped moisture preservation layer 12 is a polyethylene film.

[0045] Through the arrangement of the polyethylene film, the arc-shaped moisture preservation layer 12 can lock moisture, so as to carry out moisture preservation and maintenance operations on the concrete beam-column body 18 for a long time. Through the arrangement of the circular groove 16, the rotation of the threaded rod 3 is reduced from interfering with the fixing plate 2.

[0046] Working principle:

[0047] As Figure 1 、 Figure 2 、 Figure 3and Figure 4 As shown in Figure 4 , first, unfold the first arc-shaped plate 1 and the second arc-shaped plate 14 and place them on the outer side of the concrete beam-column body 18. Use bolts to fix the first fixing block 7 outside the first arc-shaped plate 1 and the second arc-shaped plate 14. Subsequently, turn the threaded rod 3 respectively, so that the arc-shaped clamping plate 5 moves horizontally under the limiting action of the sliding plate 4. At the same time, soak the arc-shaped moisture preservation layer 12, and then use bolts to fix the two second fixing blocks 17, so that the annular plates 9 at both ends can become a complete annular plate 9, and place the annular plate 9 into the arc-shaped groove 8. When the arc-shaped clamping plate 5 clamps the concrete beam-column body 18, it will drive the sliding plate 4 to slide inside the first arc-shaped plate 1 and the second arc-shaped plate 14, and then can drive the fixing plate 2 to move. At the same time, it can drive the clamping strip 6 at the bottom of the fixing plate 2 to extend into the arc-shaped groove 8 and be engaged with the corresponding clamping groove 10, so as to facilitate the installation of the annular plate 9;

[0048] After the annular plate 9 is installed, the arc-shaped airbag 13 can be inflated through the air inlet pipe 19. Driven by the arc-shaped airbag 13 with expanded volume, the arc-shaped moisture preservation layer 12 will be closely attached to the outer side of the concrete beam-column body 18. Through the setting of the corrugated pipe 11, it can play an important protective role for the arc-shaped airbag 13, reduce the scratch caused by external sharp objects to the arc-shaped airbag 13, and then the arc-shaped airbag 13 can be used for a long time.
