[0028] See also Figure 1 , Figure 2 and Figure 3 ; In order to cast underground prefabricated foundations of different specifications, the present invention provides a concrete foundation casting mold, including a base mold platform 1, a bottom mold frame 2, a conical mold frame 3 and a column mold 4; the base mold platform 1 has a base mold surface; the bottom mold frame 2 is arranged on the base mold surface; the conical mold frame 3 has a bottom opening and a top opening, the bottom opening of the conical mold frame 3 covers the bottom mold frame 2, the inner cover wall of the conical mold frame 3 is tightly attached to the top frame edge of the bottom mold frame 2, and a first overlapping slope 32 is provided at the top opening of the conical mold frame 3; and the bottom of the column mold 4 is connected to the top opening of the conical mold frame 3, and is provided with a second overlapping slope 41 overlapping the first overlapping slope 32, and a positioning plate 5 for limiting the casting height of the column mold 4 is provided in the column mold 4. In the present invention, the bottom mold frame 2 and the conical mold frame 3 are non-rigidly fitted and attached, and the conical mold frame 3 and the column mold 4 are stabilized by the pressure between the hypotenuses, so that the overall prefabricated basic mold can be reused many times and has a wide range of adaptability. By replacing the column mold 4 and the bottom mold frame 2, a set of molds can be made into various specifications without delaying the construction period, and production and storage can be made in advance. It should be noted that the fitting method can be non-rigid or rigid; non-rigid is interpreted as the interaction of pressure between the bottom mold frame 2 and the conical mold frame 3 to fit each other stably, and rigid is interpreted as the bottom mold frame 2 and the conical mold frame 3 are fixedly connected by welding, gluing, etc.

[0029] It should be noted that the prefabricated foundation of the building structure includes a base and columns. In this embodiment, the base is cast by enclosing a conical mold frame 3 and a bottom edge mold frame 2 , and the columns are cast by a column mold 4 .

[0030] The purpose of the first embodiment is that different building structures require different prefabricated foundations, including the size of the prefabricated foundation base and the size of the column, which will be adapted to different sizes due to actual construction requirements. In order to achieve this purpose, the bottom edge mold frame 2 in this embodiment is selected from different sizes, and the size of the bottom edge mold frame 2 is smaller than the bottom opening of the conical mold frame 3. The bottom edge mold frame 2 and the base mold platform 1 constitute the bottom template for casting the prefabricated foundation base, and the conical mold frame 3 and the bottom edge mold frame 2 are closely fitted, so the inner wall of the conical mold frame 3 constitutes the main structure casting template of the prefabricated foundation base.

[0031] In view of the above, in order to realize the purpose that different building structures require different prefabricated foundations, the column mold 4 in this embodiment is selected from different sizes, and the slope of the second overlapping slope 41 of the column mold 4 is equal to the slope of the first overlapping slope 32. Preferably, no matter what size the column mold 4 is selected, it is fixed by the downward pressure between the second overlapping slope 41 and the first overlapping slope 32.

[0032] Normally, the bottom edge formwork 2 can be placed on the base formwork 1, but the prefabricated foundation usually needs to be vibrated during pouring, and on the other hand, it is also for the relative stability between the bottom edge formwork 2 and the base formwork 1. For this purpose, the material of the bottom edge formwork 2 and the base formwork 1 is selected as a magnetically absorbable metal. In the field of modern steel-concrete building structures, structural parts or formworks tend to choose steel. On the one hand, the structural strength is large, and on the other hand, compared with wooden formworks, steel formworks do not absorb water, so the concrete after pouring is neat and flat, without honeycomb pores.

[0033] Furthermore, the bottom mold frame 2 and the base mold platform 1 are fixed by a magnetic positioning member 6. The magnetic positioning member 6 can determine the position relatively on the one hand, and can also stabilize the structure on the other hand. Preferably, the magnetic positioning member 6 includes a magnetic gasket 61, a bracket 62 and a leveling bolt 63; the magnetic gasket 61 is arranged between the bottom mold frame 2 and the base mold platform 1; the bottom of the bracket 62 is connected to the magnetic gasket 61, and the top of the bracket 62 has a mounting end, and a threaded hole is provided on the mounting end facing the conical mold frame 3; the leveling bolt 63 is arranged in the threaded hole and tightens the conical mold frame 3. Preferably, the edge of the conical mold frame 3 extends outward to form a cover plate, and the leveling bolt 63 tightens the cover plate of the conical mold frame 3.

[0034] The leveling bolts 63 can stabilize the structure on one hand, and can also level the bottom edge mold frame 2 mainly through downward pressure on the other hand.

[0035] Preferably, the bracket 62 is a bracket 62 plate, the mounting end is a mounting plate disposed on the top of the bracket 62 plate, and the magnetic gasket 61 is disposed on the bottom of the bracket 62 plate.

[0036] Since the conical mold frame 3 will deform, a stiffening rib 31 is added. The stiffening rib 31 is a supporting structure composed of a tube and is arranged on the outer wall of the conical mold frame 3 .

[0037] Another purpose of this embodiment is to improve the assembly efficiency of the prefabricated foundation mold. To achieve this purpose, the conical mold frame 3 is assembled by at least a first cover body 33 and a second cover body 34. Here, a specific shape of the conical mold frame 3 is selected for description. The conical mold frame 3 is in the shape of a cone, that is, the structure when the base of the prefabricated foundation is a square cone. It should be noted that the square cone described in this embodiment is not the only shape of the prefabricated foundation base. Its shape has various shapes according to the construction. However, in the current stage of construction, the square cone shape is the most used. Therefore, the conical mold frame 3 is used as a casting template, and its shape is also a square cone shape, but in order to connect the column mold 4 and the bottom edge mold frame 2, there are openings at the top and bottom.

[0038] Furthermore, the shapes of the first cover body 33 and the second cover body 34 are symmetrical along the diagonal of the conical mold frame 3 of the square cone. The two are fixed by bolts. Specifically, ear plates (311, 321) are arranged near the diagonal of the square cone on the first cover body 33 and the second cover body 34. The ear plates (311, 321) of the two cover bodies are provided with corresponding cover body mounting holes, and then they are connected together by bolts through holes, which can realize quick disassembly and assembly, and is also convenient for demolding after pouring.

[0039] In view of the above, in order to achieve the above-mentioned purpose of improving the assembly efficiency of the prefabricated foundation mold, the column mold 4 is assembled by at least the first mold body 43 and the second mold body 44. Because the prefabricated foundation is composed of a base and a column, the column is cast by the column mold 4, and the base is cast by the conical mold frame 3; after the conical mold frame 3 is assembled, in order to achieve the convenience of synchronous demolding, the column can also be assembled. Furthermore, the first mold body 43 and the second mold body 44 are connected by bolts through holes. Similarly to the structural mode of the conical mold frame 3, ear plates are set at the positions of the first mold body 43 and the second mold body 44 near the diagonal of the column mold 4, and the ear plates of the two are provided with mold mounting holes corresponding to the position, and then connected together by bolts through holes, which can realize quick disassembly and assembly, and also facilitate demolding after casting. Preferably, the column mold 4 here uses a square column.

[0040] Preferably, in order to determine the heights of different columns, a positioning plate 5 is provided in the column form 4, and after the concrete pouring reaches a certain height, the positioning plate 5 is pressed against the concrete to a defined height.

[0041] The pouring method of the present invention is:

[0042] First, select the required size of the bottom mold frame 2 and the size of the column mold 4, place the bottom mold frame 2 on the base mold platform 1, and fit the conical mold frame 3 to the bottom mold frame 2. Because the conical mold frame 3 is a square cone, the inner wall is a bevel. The positions of the bottom mold frames 2 of different sizes on the bevel are different, but it should be noted that no matter what the bottom mold frame 2 is, its bottom is at least flush with the bottom of the conical mold frame 3 or protrudes from the bottom opening of the conical mold frame 3. When the bottom of the bottom mold frame 2 is flush with the bottom of the conical mold frame 3, the conical mold frame 3 and the bottom mold frame 2 are jointly supported on the base mold platform 1; and when the bottom of the bottom mold frame 2 protrudes from the bottom opening of the conical mold frame 3, the bottom mold frame 2 bears the force of the entire prefabricated basic mold;

[0043] Then, overlap the second overlapping slope 41 of the column mold 4 on the first overlapping slope 32 of the conical mold frame 3, and the mold assembly is quickly completed; then pouring is carried out. After pouring to a certain height in the column mold 4, the positioning plate 5 is adjusted to flatten it. After 6-12 hours of preliminary shaping, it can be demolded. The column mold 4 and the conical mold frame 3 are quickly disassembled along the diagonal to remove the mold, and the production of a prefabricated foundation is completed.

[0044] The beneficial effects of the present invention are:

[0045] 1. Through the adjustable and replaceable column formwork, it can adapt to foundations of various burial depths;

[0046] 2. The conical mold frame has a certain slope, which creates a downward pressure to ensure stability.

[0047] 3. By adjusting the size of the bottom edge mold frame, it can be adapted to prefabricated foundations of various volumes;

[0048] 4. Forward casting, no need to reverse the mold twice, reducing labor costs;

[0049] 5. The magnetic positioning parts can be flexibly disassembled and assembled, and only one person is needed to operate;

[0050] 6. Steel molds, a set of molds can be reused tens of thousands of times without deformation, energy-saving, low-carbon and environmentally friendly;

[0051] 7. Standardized molds, no need for re-customization, mass production reduces costs;

[0052] 8. No requirements for the environment, both dry and wet conditions are acceptable, production can be arranged during off-season to ensure factory operation efficiency;

[0053] 9. Concrete pouring and curing can be completed in the factory, which increases the prefabrication rate;

[0054] 10. The above measures can save materials and energy for society.

[0055] When it is necessary to point out, the foundation is divided into two forms: square foundation and rectangular foundation. The short column part can also be a long column. The size of the bottom edge mold frame is also different according to the needs of the construction. The present invention is intended to protect the structure described above. The size of each component is not specified, but they are all necessary adjustments that can be made by technical personnel in this field according to actual construction needs, and should be protected within the scope of the present invention.

[0056] The present invention is described in detail above in conjunction with the embodiments of the accompanying drawings. A person skilled in the art can make various variations of the present invention according to the above description. Therefore, certain details in the embodiments should not constitute a limitation of the present invention, and the scope of protection of the present invention shall be defined by the scope of the attached claims.
