Therefore, simplifying the installation and disassembly process of production molds is a key technical problem that needs to be addressed and is crucial for improving the production efficiency of precast walls.

[0004] Therefore, there is an urgent need to design a new mold for producing precast walls. This mold should not only ensure the quality of the precast walls but also be easy to install and disassemble, enabling on-site operators to produce precast walls more efficiently and on a large scale. This will achieve the technical effect of accelerating production efficiency and increasing workshop capacity. Ultimately, this will enhance the company's market competitiveness to adapt to fierce domestic and international market competition, thereby improving the company's economic benefits, promoting industry development, and creating positive social benefits.

[0039] The specific embodiments of this utility model application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this disclosure.

[0040] In the technical solutions disclosed in this utility model application, unless otherwise stated, directional terms such as "up," "down," "left," and "right" generally refer to those defined based on the drawing direction of the corresponding figures, while "inner" and "outer" refer to those inside and outside relative to the outline of the component or structure itself. Furthermore, in the description of the accompanying drawings, the same reference numerals in different figures denote the same elements.

[0041] This utility model application discloses a composite mold for producing precast walls, such as... Figure 1 As shown, it includes:

[0042] Mold 1 is a rectangular structure;

[0043] The wall mold 2 is a rectangular frame structure, set on the mold table 1, and is used for casting and forming the precast wall;

[0044] The support component 3 is installed on the mold table 1 in a quick and easy manner along the periphery of the wall mold 2, and is used to support and fix the wall mold 2.

[0045] The window opening mold 4 is a rectangular frame structure, set on the mold platform 1 inside the wall mold 2, and is used for casting and forming the window opening of the precast wall;

[0046] The positioning component 5 is quickly and easily installed on the mold platform 1 inside the window opening mold 4, and is used to position and fix the window opening mold 4.

[0047] The above technical solution mainly focuses on the support component 3 and the positioning component 5. Through the optimized and improved design of the support component 3 and the positioning component 5, the two components not only play the roles of support and fixation, and positioning and fixation, but also have the characteristics of being able to be quickly installed before the pouring construction and quickly disassembled after the pouring construction. This improves the production efficiency of precast walls and greatly shortens the production cycle of a single precast wall.

[0048] This composite mold, while ensuring the quality of the precast walls produced, also has the advantages of easy installation and disassembly. This enables on-site operators to produce precast walls more efficiently and on a large scale, achieving the technical effects of accelerating production efficiency and increasing enterprise capacity. This enhances the enterprise's market competitiveness, adapts to domestic and international market competition, and ultimately improves the enterprise's economic benefits, promotes industry development, and creates positive social benefits.

[0049] In this embodiment, such as Figure 1 , Figure 4 , Figure 5 , Figure 6 As shown, the wall mold 2 is formed by several templates 201.

[0050] Support component 3 includes:

[0051] Several fixed magnetic boxes 8 are spaced apart on the outside of each template 201. Each fixed magnetic box 8 is equipped with a connector 7 for connecting to the template 201. The fixed magnetic boxes 8 are installed on the template 1 using magnetic force, and then supported and fixed to the template 201 by connecting to the connector 7. Installation is simple; disassembly is easy as the fixed magnetic boxes 8 can be removed simply by using an operating lever. Furthermore, as... Figure 1 , Figure 2 , Figure 5 , Figure 6 As shown, template 201 is made of bamboo plywood; the support assembly 3 also includes several reinforcing plates 6, which are installed on the outer end face of each template 201. Template 201 is connected to connector 7 through reinforcing plates 6 and installed on the mold table 1.

[0052] In this design, bamboo plywood is selected for formwork 201. As a new type of building formwork material, bamboo plywood is composed of bamboo skin and adhesive. Compared with traditional wooden and steel formwork, bamboo plywood formwork has the following advantages:

[0053] ① Lightweight: Bamboo plywood is lighter than wooden formwork and more than 20% lighter than steel formwork. It is easier to install and disassemble, requires less labor from workers, and further improves production efficiency.

[0054] ② High hardness: Bamboo plywood is harder than wooden plywood, making it more durable and less prone to damage during use;

[0055] ③ Durability and turnover advantages: Bamboo plywood is waterproof and corrosion resistant, and can usually be reused 8-12 times, which is 2-3 times that of steel formwork (usually 3-5 times);

[0056] ④ Molding accuracy and cost-effectiveness: Thickness deviation is controlled within ±0.2mm, joints are small, and the concrete surface is smooth after demolding, reducing repair work. Long-term usage costs are more than 60% lower than steel formwork.

[0057] ⑤ Environmental protection and adaptability: Bamboo is naturally moisture-resistant, elastic, and not easily affected by the seasons.

[0058] The reinforcement plate 6 is installed on the outer end face of the template 201 to strengthen the overall structural strength of the bamboo plywood, prevent it from deforming, and ensure the quality of the cast precast wall. At the same time, the reinforcement plate 6 is connected to the connector 7, and then to the fixed magnetic box 8.

[0059] Specific installation methods, such as Figure 2 , Figure 5 , Figure 6 As shown, the reinforcing plate 6 is a channel steel, with both flanges extending outwards to form an upper flange and a lower flange. Mounting holes 602 are spaced apart on both the upper and lower flanges. Each reinforcing plate 6 is mounted on the template 201 by inserting self-tapping screws 10 into the mounting holes 602 on the upper and lower flanges. The channel steel and the connector 7 can include various connection methods, such as welding, bolt connection, slot insertion connection, pin connection, etc. Any method that can securely connect the channel steel and the connector 7 is considered to fall within the scope of this technical solution.

[0060] In some specific implementation methods, such as Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, several elongated holes 601 are formed on the web of the reinforcing plate 6 along the length direction;

[0061] The connector 7 is an angle connector (usually a right-angle connector), one side of which is used to connect and fix the magnetic box 8; the other side end has a slot 701, which is located outside the fixed magnetic box 8 and is used to insert into the elongated hole 601, clamp and support the reinforcing plate 6.

[0062] Insert the slot 701 into the elongated hole 601. The upper and lower inner walls of the slot clamp the channel steel (reinforcing plate 6), thereby clamping the channel steel and preventing it from flipping or tipping over, thus achieving the purpose of supporting and fixing the template 201. Figure 5 As shown, the card slot 701 can be a single-slot card slot structure; or it can be as follows: Figure 6 As shown, the structure has multiple slots;

[0063] The connector 7 and the fixed magnetic box 8 can be connected in various ways, such as: ① bolt connection, the connector 7 has a connecting elongated hole 702 on its side, the connecting elongated hole 702 can not only install bolts and nuts, but the operator can also use the connecting elongated hole 702 to adjust the length of the slot 701 of the connector 7 that is cantilevered outside the fixed magnetic box 8, that is, adjust the depth of the slot 701 inserted into the elongated hole 601; ② the connector 7 can also be welded to the fixed magnetic box 8, etc.

[0064] In other implementations, such as Figure 7 As shown, the window opening mold 4 includes four right-angle frames 401 and several side frames 402. Each right-angle frame 401 and the side frame 402, as well as adjacent side frames 402, are connected by tongue and groove joints and can be sealed and assembled together.

[0065] The design of this scheme is that the rectangular frame of the window opening mold 4 is assembled, and each right-angle frame 401 and the side frame 402 are connected by matching tongue and groove joints, and the angles of the end faces of all right-angle frames 401 and side frames 402 are equal or complementary. This design allows the side frames 402 to be combined arbitrarily. Operators can select an appropriate number of side frames 402 to connect according to the different sizes of the required window opening mold 4, so as to meet the needs of window openings of different sizes and different aspect ratios.

[0066] In some implementations, such as Figure 8 , Figure 9 , Figure 10 As shown, both ends of each right-angle frame 401 and both ends of each frame 402 are bevels. The purpose of the bevel design is that beveled ends are easier, more convenient, and faster to disassemble during the demolding process compared to right-angled ends, which can further improve production efficiency.

[0067] In some implementations, such as Figure 9 , Figure 10 As shown, each right-angle frame 401 has a connecting hole 403 on the inclined surface at both ends, and each side frame 402 has a connecting hole 403 on the inclined surface at both ends. The right-angle frame 401 and the side frame 402, as well as two adjacent side frames 402, are connected by bolts.

[0068] Furthermore, such as Figure 1 , Figure 7 , Figure 8As shown, the outer end faces of part of the right-angle frame 401 and part of the frame 402 are stepped structures 404. As can be clearly seen in the attached diagram, the stepped structure 404 includes a kick surface and a tread surface, used for casting to form a rainproof structure for the exterior window of the window opening. The term "partial" refers to the fact that in the rectangular frame structure of the window opening mold 4, the stepped structure 404 is present at three of the frame edges 402. The bottom edge of the window opening does not require the rainproof design of the stepped structure 404; therefore, the stepped structure 404 is only set on the outer end faces of part of the right-angle frame 401 and part of the frame 402.

[0069] In other implementations, such as Figure 1 ,like Figure 7 ,like Figure 8 As shown, the positioning component 5 includes:

[0070] Several limiting components 9 are installed at intervals on the mold table 1 along the inner frame of the rectangular frame of the window opening mold 4, to abut against the bottom surfaces of the right-angle frame 401 and the side frame 402; to prevent the window opening mold 4 from shifting during concrete pouring, and to serve a positioning and fixing function. Specifically, the limiting components 9 can be welded to designated positions on the mold table 1, and a wide range of components can be selected, such as small bolts, small nuts, and small pipe fittings; they can also be small magnetic blocks with strong magnetic force.

[0071] Several fixed magnetic boxes 8 are installed at intervals on the mold table 1 along the inner frame of the rectangular frame of the window opening mold 4. These boxes abut against the inner end face of the frame 402, preventing the frame 402 from being subjected to concrete pressure during pouring and thus preventing it from turning inward and affecting the quality of the poured window opening. It should also be noted that... Figure 7 The drawing only shows the fixed magnetic box 8 and the limiting member 9 as examples; the quantity of both shown in the figure does not represent the quantity in actual applications.

[0072] This utility model application exemplarily describes the steps of using the installation and positioning device, as follows:

[0073] S1. Weld several nuts on the mold table 1 at the set positions as the limiting parts 9 of the positioning component 5, and then assemble the window mold 4 according to the positions of the nuts.

[0074] S2. After the window opening mold 4 is assembled, several fixing magnetic boxes 8 are installed inside it, and the fixing magnetic boxes 8 are placed against the inner end face of the frame 402.

[0075] S3. Install the wall mold 2 on the mold table 1 according to the set position, and then install the support component 3 around it;

[0076] S4. Concrete pouring;

[0077] S5. After the concrete has cured to the required strength, remove the wall mold 2, support components 3, window opening mold 4, and positioning components 5, and then hoist the precast wall out.

[0078] S6. The composite mold is reused to begin pouring the next precast wall.

[0079] It should also be noted that the various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, this application will not describe the various possible combinations separately.

[0080] Furthermore, various different embodiments of this utility model application can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this utility model application.
