[0031] Please refer to Figure 1 and Figure 2 The concrete pouring mold provided in the embodiment of the utility model comprises a plurality of plastic mold units 100, a bottom mold assembly 200, a side mold assembly 300, a modular box body 400, a fixing assembly, hardware 500 and a steel platform 600; the plurality of plastic mold units 100 are detachably connected to form the bottom mold assembly 200 and the side mold assembly 300 respectively; the bottom mold assembly 200 and the side mold assembly 300 are both fixed on the end face of the steel platform 600; the bottom mold assembly 200 and the side mold assembly 300 are located on both sides of the bottom steel beam of the modular box body 400 and are used for pouring the bottom plate of the modular box body 400; the hardware 500 is fixedly connected to the side mold assembly 300 and the steel platform 600 through the fixing assembly.

[0032] In this embodiment, the bottom mold assembly 200 is located on the inner side of the bottom steel beam of the modular box 400 to be poured, and the side mold assembly 300 is located on the outer side of the bottom steel beam of the modular box 400 to be poured. The bottom mold assembly 200 and the side mold assembly 300 are located on both sides of the bottom steel beam of the modular box 400, so that the modular box 400 can be accurately positioned during pouring. Not only helps to ensure the tightness of the connection between the modular box 400 and the bottom plate, but also can ensure that the concrete is evenly distributed at the bottom of the modular box 400, avoiding the situation that the local concrete is too thick or too thin, improving the accuracy and quality of pouring. Because the size of the modular box 400 to be poured is not unique, for different sizes of the modular box 400, the number and combination method of the molding unit 100 can be adjusted to adapt to the shape and size of the different modular boxes 400, meet the diversified construction requirements. In addition, because the molding unit 100 has relatively small volume and light weight, it occupies small space during transportation, is convenient to carry and transport, and reduces transportation cost and difficulty. At the same time, on the one hand, when not in use, these molding units 100 can be easily disassembled and stacked for storage, saving storage space; on the other hand, during use, if a molding unit 100 is damaged, such as cracking, deformation, etc., only the damaged molding unit 100 needs to be replaced, without the need to replace the entire mold assembly, greatly reducing the maintenance cost and maintenance time, improving the overall service life and use efficiency of the mold.

[0033] Specifically, the process of pouring the bottom plate of the modular box 400 through the concrete pouring mold is as follows: first, according to the structure of the modular box 400 to be poured, the size of the concrete plate at the bottom of the modular box 400 is determined. Second, according to the different sizes of the concrete plate at the bottom of the modular box 400, different sizes of the mold unit 100 are selected for combination to form the bottom mold assembly 200 and the side mold assembly 300, wherein the adjacent two mold units 100 are fixedly connected through bolts. Third, after assembling and splicing the bottom mold assembly 200 and the side mold assembly 300 according to the requirements of the construction process, the bottom mold assembly 200 is respectively welded and fixed on the end face of the steel platform 600 through the fixing assembly, and the position of the bottom mold assembly 200 is adjusted according to the construction requirements. Fourth, according to the weight and size of the modular box 400, appropriate hoisting rigging (such as a crane) and hoisting method are selected, such as four-point hoisting method, to ensure that the box remains balanced and stable during hoisting. Fifth, the side mold assembly 300 is fixed on the steel platform 600 through the hardware 500 and the fixing assembly, and the position of the side mold assembly 300 is adjusted according to the construction requirements. The steel platform 600 is placed horizontally on the ground, the bottom mold assembly 200 is parallel to the steel platform 600, and the side mold assembly 300 is perpendicular to the steel platform 600. The steel platform 600 provides a solid and flat working foundation for the entire concrete pouring mold, which can evenly distribute the weight of the bottom mold assembly 200 and the concrete, preventing the bottom mold assembly 200 from deforming or sinking due to uneven ground or insufficient bearing capacity during pouring.

[0034] Sixth, after the installation of the bottom mold assembly 200 and the side mold assembly 300 is completed, the surface of the bottom mold assembly 200 and the side mold assembly 300 is thoroughly cleaned to remove dust, debris, and oil stains on the surface. After the mold is dry, evenly apply release agent to avoid missing or over-thick coating, ensuring that the concrete can be smoothly demolded after pouring, while ensuring the quality of the concrete surface. Seventh, according to the design drawing requirements, steel bars are bound between the bottom mold assembly 200 and the steel beam at the bottom of the modular box 400. Eighth, after the steel bar binding is completed and passes the inspection, the concrete pouring operation is carried out; at the same time, after the concrete pouring is completed, timely maintenance operation is carried out, which can adopt the method of covering plastic film and watering to ensure that the concrete reaches the design strength requirement. Ninth, when the concrete reaches a certain strength (such as 70% of the design strength), the modular box 400 with the poured bottom plate is transported to the designated storage site using a dedicated transportation equipment (such as a flatbed trailer).

[0035] In an embodiment, as Figure 2 and Figure 3As shown, each of the plurality of molding units 100 comprises a molding body 110, a plurality of bolt holes 120 and a first screw hole; the plurality of bolt holes 120 and the first screw hole are arranged on the molding body 110; the plurality of bolt holes 120 on two adjacent molding bodies 110 are opposite to each other, and are fixedly connected with the plurality of bolt holes 120 by bolts to fix the two adjacent molding bodies 110.

[0036] In the embodiment, according to the different sizes of the modular box 400 to be poured, different sizes of the molding units 100 are selected to be combined to adapt to the different sizes of the modular box 400. For example, the size specifications of the molding units 100 that can be generally selected include 600m*800m, 300m*800m and 200m*800m. The bottom mold assembly 200 and the side mold assembly 300 formed by the combination and disassembly of the molding units 100 are aligned with each other in the installation process, and the bolt holes 120 on the two adjacent molding bodies 110 are fixedly connected by bolts (not shown in the figure) arranged in the bolt holes 120 (not shown in the figure) on the two adjacent molding bodies 110. The bolt for fixing the two adjacent molding bodies 110 can be a bolt. Through the precise processing of the bolt holes 120 and the bolt connection, a tight and firm connection structure can be formed between the adjacent molding units 100. In the concrete pouring process, the mold needs to withstand the lateral pressure and vibration force of the concrete, and the bolt fixing connection can effectively prevent the gaps and separation between the molding units 100, avoid the occurrence of concrete leakage, and ensure the quality and forming effect of the concrete pouring. It should be noted that the specific size of the molding unit 100 is not limited in the present application, and it can be set according to the actual construction needs.

[0037] In addition, the bolt connection makes the installation and disassembly of the molding units 100 simple and easy to operate. Workers at the construction site only need to use simple tools (such as wrenches) to complete the assembly and disassembly of the mold, without the need for professional and complex equipment and technology, reducing the construction difficulty and labor cost. Moreover, if a molding unit 100 is damaged (such as scratches, cracks, etc.) during use, the damaged unit can be easily disassembled and replaced with a new molding unit 100, without the need to replace the entire mold assembly, greatly improving the maintenance efficiency and service life of the mold, and reducing the construction delay and cost increase caused by mold damage.

[0038] In an embodiment, as Figure 1 , Figure 2 and Figure 6As shown, the bottom mold assembly 200 comprises a bottom mold body 210 and a support assembly 220; the bottom mold body 210 is composed of the plurality of mold bodies 110 fixedly connected by the bolts; the bottom mold body 210 is connected to the support assembly 220, and the bottom mold body 210 is fixed to the end face of the steel platform 600 through the support assembly 220.

[0039] In the embodiment, the mold bodies 110 of appropriate sizes are selected according to the size of the modular box 400 to be poured with the bottom plate, two adjacent mold bodies 110 are fixedly connected by the plastic bolts to form the bottom mold body 210, and the size of the bottom mold body 210 is adapted to the bottom of the modular box 400 to be poured with the bottom plate. The steel platform 600 is laid on the horizontal ground, the first end face of the bottom mold body 210 is fixedly welded to the steel platform 600 through the support assembly 220, and the second end face of the bottom mold body 210 is used to support the poured cement to form the bottom plate of the modular box 400. The first end face of the bottom mold body 210 is opposite to the second end face, the first end face is the end face facing the steel platform 600, and the second end face is the end face facing the modular box 400.

[0040] The support assembly 220 can uniformly transmit the weight of the poured concrete borne by the bottom mold body 210 to the steel platform 600 on the one hand, and can prevent the bottom mold body 210 from being deformed or damaged due to excessive local stress on the other hand; on the other hand, the support assembly 220 can also support the bottom mold body 210, so that the distance between the plane where the second end face of the bottom mold body 210 is located and the plane where the steel platform 600 is located is the same as the distance between the plane where the bottom plate to be poured of the modular box 400 is located and the plane where the steel platform 600 is located. For example, assuming that the thickness of the bottom mold body 210 is 65 mm, and the distance between the bottom plate to be poured of the modular box 400 and the plane where the steel platform 600 is located is 95 mm, at this time, the support assembly 220 with a thickness of 30 mm can be selected to be arranged between the bottom mold body 210 and the steel platform 600, so that the distance between the plane where the second end face of the bottom mold body 210 is located and the plane where the steel platform 600 is located is the same as the distance between the plane where the bottom plate to be poured of the modular box 400 is located and the plane where the steel platform 600 is located.

[0041] In an embodiment, as shown in Figure 4 and Figure 6 As shown, the support assembly 220 comprises a plurality of square tubes 221 and a connecting body 222; one side end face of the plurality of square tubes 221 is fixed to the steel platform 600, the side end face of the plurality of square tubes 221 away from the steel platform 600 is fixed to the bottom mold body 210, the plurality of square tubes 221 are arranged at intervals and parallel to each other; the connecting body 222 is fixedly connected to the plurality of square tubes 221; the connecting body 222 is provided with a through hole 223.

[0042] In the embodiment, the number of the connecting member bodies 222 can be set as required. The several connecting member bodies 222 are respectively welded and fixed on the several square tubes 221. The specifications and the number of the several square tubes 221 are set according to the specific construction needs. In the specific construction, first, the size of the bottom mold body 210 is calculated according to the size of the modular box body 400 to be poured and the bottom mold body 210 is erected; second, the appropriate number and thickness of the square tube 221 are selected according to the size of the bottom mold body 210, and the several connecting member bodies 222 are welded and fixed on each square tube 221; then, each square tube 221 welded with the connecting member body 222 is fixed on the steel platform 600 in parallel and at intervals, wherein the length of the square tube 221 is equal to the length of the bottom mold body 210; finally, the erected bottom mold body 210 is fixed on the several square tubes 221 arranged.

[0043] Specifically, the bottom mold assembly 200 further comprises a screw; the screw is respectively threaded in the first screw hole and the through hole 223 to fixedly connect the connecting member body 222 and the mold body 110.

[0044] In the embodiment, compared with the whole type difficult to disassemble bottom mold structure, the screw (not shown in the figure) is threaded in the first screw hole (not shown in the figure) and the through hole 223 on the connecting member body 222 to realize the fixed connection of the connecting member body 222 and the mold body 110, which greatly saves the labor and time cost when disassembling, and the disassembled screw and the mold body 110 can be reused, thereby improving the utilization rate of construction materials and saving the construction cost. The number and type of the screw can be set according to the specific construction needs. The connecting member body 222 and the mold body 110 on the square tube 221 are connected and fixed together by the screw, which can prevent the position of the mold body 110 from deviating due to the impact force generated by the pouring of concrete, resulting in quality problems of the bottom plate pouring, and is conducive to disassembly.

[0045] In an embodiment, as shown in Figure 1 The side mold assembly 300 comprises a first side mold body 310, a second side mold body 320, a third side mold body 330 and a fourth side mold body 340; the first side mold body 310, the second side mold body 320, the third side mold body 330 and the fourth side mold body 340 are all composed of the several mold units 100; the first side mold body 310 is parallel to the third side mold body 330; the second side mold body 320 is parallel to the fourth side mold body 340.

[0046] In the embodiment, the lengths of the steel beams at the bottom of the modular box 400 are different due to different sizes of the modular box 400. Therefore, the plastic mold units 100 of corresponding sizes are selected according to the sizes of the steel beams at the bottom of the modular box 400 to be poured with the bottom plate, so as to be combined into the first side mold body 310, the second side mold body 320, the third side mold body 330 and the fourth side mold body 340 respectively. The lengths of the first side mold body 310, the second side mold body 320, the third side mold body 330 and the fourth side mold body 340 are greater than or equal to the lengths of the steel beams at the bottom of the modular box 400, so that the concrete can be shielded from the side during pouring to realize the pouring of the bottom plate of the modular box 400.

[0047] Since the side mold assembly 300 is located outside the steel beams at the bottom of the modular box 400, the first side mold body 310 is parallel to the third side mold body 330, and the second side mold body 320 is parallel to the fourth side mold body 340, so that the concrete poured around the periphery of the modular box 400 is blocked by the side mold assembly 300, thereby facilitating the pouring and forming of the bottom plate.

[0048] In an embodiment, as shown in Figure 1 , Figure 4 and Figure 6 , the hardware 500 includes a hardware body 510; the hardware body 510 includes a first fixing part 511, a second fixing part 512, a third fixing part 513 and a second screw hole 514; the bottom of the first fixing part 511 is fixed vertically to the second fixing part 512; the second fixing part 512 is parallel to and fixed to the steel platform 600; the two ends of the third fixing part 513 are fixedly connected to the first fixing part 511 and the second fixing part 512 respectively; and the second screw hole 514 is adjacent to the top of the first fixing part 511.

Specifically, the first fixing part 511 is provided with a second screw hole 514 adjacent to the top thereof, and the first fixing part 511 and the side mold assembly 300 are fixed by the screw matched with the second screw hole 514. The second fixing part 512 is perpendicular to the first fixing part 511, that is, the second fixing part 512 is parallel to the steel platform 600.

[0051] In another embodiment, the second fixing part 512 is provided with a third screw hole (not shown in the figure) for matching with a bolt. The bolt is matched with the third bolt hole 120 to fix the second fixing part 512 on the horizontal ground.
