After the prefabricated column components are installed, special seat slurry is required to seal the warehouse. After the sealing seat slurry meets the requirements, sleeve grouting is carried out. During the grouting process, the seat slurry strength is insufficient and the warehouse bursts, and the grouting effect is extremely poor. After the grouting is completed, the seat slurry for sealing the exposed warehouse needs to be removed, which affects the appearance quality of the components, and at the same time causes waste of seat slurry and increases costs.

The existing steel molds for sealing warehouses have the following problems when in use: In a prefabricated column grouting sealing warehouse structure with the publication number: CN207829155U, it is proposed that "it includes a prefabricated column and a base plate; there is a joint gap between the bottom of the prefabricated column and the upper surface of the base plate; the bottom of the prefabricated column is surrounded by a detachable closed water stop ring, the inner wall surface of the water stop ring is arranged adjacent to the outer wall surface of the prefabricated column, and the area enclosed by the water stop ring is larger than the cross-sectional area of the prefabricated column; the top of the water stop ring is higher than the bottom of the prefabricated column." Although the above device can form a hoop effect on the mortar for sealing the warehouse and avoid warehouse explosion.

After grouting, the prefabricated column needs to use sealing materials to seal the grouting holes and overflow holes. After demolding, the grouting holes and overflow holes on the surface of the prefabricated column look poor and need to be plastered and leveled, which increases the construction cost and time. Therefore, we need a steel mold for sealing warehouses that can be formed in one time to improve the practicality of the device.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Please refer to Figures 1-4, a precast column grouting sealing steel mold, whose structure includes a precast concrete column 1 and a sealing mechanism 6, a concrete structural plate 2 is arranged below the precast concrete column 1, a grouting hole 3 is arranged on the outer surface of the precast concrete column 1, and an overflow hole 4 is arranged above the grouting hole 3, a mold mechanism 5 is arranged around the precast concrete column 1, and a sealing mechanism 6 is arranged above the mold mechanism 5, and the sealing mechanism 6 includes a fixing frame 604 and an insert 605.

Two sealing steel molds 501 are arranged around the precast concrete column 1, and a rubber sealing strip 502 is arranged between the precast concrete column 1 and the sealing steel mold 501. The sealing steel mold 501 is used for forming and fixing the precast column to ensure the stability of the shape and size of the precast column during the grouting process. The rubber sealing strip 502 is used for sealing the gap between the steel mold and the concrete structural plate 2 to prevent slurry leakage, prevent waste of construction materials, and save construction costs.

The sealing steel mold 501 is fixed to the upper surface of the concrete structure plate 2 by fixing bolts 503. The fixing bolts 503 are used to fix the sealing steel mold to the concrete structure plate 2 to ensure its stability and position, thereby enhancing the stability of the device.

Fixed ears 504 are provided at both ends of the sealing steel mold 501, and two adjacent fixed ears 504 are fixed by fixed connecting pieces 505. The fixed ears 504 are threadedly connected to the fixed connecting pieces 505. The fixed ears 504 are used to connect the sealing steel mold 501 and the fixed connecting pieces 505, and quick installation and disassembly are achieved through threaded connection.

A rotating support 601 is provided on the upper surface of the sealing steel mold 501. The rotating support 601 is rotatably connected to the connecting rod 603 through a rotating shaft 602. The lower surface of the fixed frame 604 is fixedly connected to the top of the connecting rod 603. The insert 605 is arranged inside the fixed frame 604. The rotating support 601 provides a rotating function for the sealing mechanism 6, which is convenient for installation and disassembly.

The sizes of the two oppositely arranged fixed frames 604 match each other, and the two oppositely arranged fixed frames 604 form a detachable structure through the insert 605. By inserting 604 into the fixed frame 605, the grouting hole 3 and the overflow hole 4 can be easily blocked.

The size of the connecting rod 603 matches the size of the insert 605, the inner diameter of the connecting rod 603 matches the outer diameter of the precast concrete column 1, the insert 605 fits tightly against the precast concrete column 1, and the insert 605 ensures the flatness of the surface of the precast concrete column 1 structure after the device is disassembled, eliminating the subsequent leveling and plastering steps and saving construction time.

A knocking block 606 is fixedly connected to the outer surface of the insert piece 605 . The knocking block 606 is fixed to the outer surface of the insert piece 605 , which is convenient for knocking with a tool to ensure that the insert piece is smoothly inserted into the fixing frame 604 .

Working principle: First, the device is prefabricated according to the size determined by the construction drawing, and the surface of the concrete structure plate 2 is measured and laid out to facilitate the positioning of the device. A 20mm gap is reserved between the sealing steel mold 501 and the precast concrete column 1, and the rubber sealing strip 502 is coated on the root of the precast concrete column 1. The sealing steel mold 501 is surrounded on the outer surface of the rubber sealing strip 502, and the sealing steel mold 501 is positioned and installed using the fixing bolts 503. The fixing connector 505 is inserted into the fixing ears 504 of the two adjacent sealing steel molds 501. After the device is tightened, the rubber sealing strip 502 fills the gap between the sealing steel mold 501 and the precast concrete column 1 to prevent grouting leakage. Then, the fixing frame 604 is lifted up to make the fixing frame 604 fixed. The fixed frame 604 surrounds the surface of the precast concrete column 1, and the fixed frame 604 drives the connecting rod 603 to move, and the connecting rod 603 drives the rotating shaft 602 to rotate in the rotating support 601, and the grouting pipe is inserted through the connecting rod 603 into the grouting hole 3 for grouting. When slurry overflows, the insert 605 is inserted at the corresponding position to seal the overflow hole 4. After the grouting is completed, the insert 605 is inserted to seal the grouting hole 3. Finally, when the slurry solidifies, the insert 605 can be easily removed from the fixed frame 604 by knocking the knocking block 606 with a tool. The device can be disassembled by removing the fixed connector 505 and the fixing bolt 503, which is convenient for next use. In this way, a method for using a precast column grouting and sealing warehouse steel mold is completed.
