[0025] Please refer to the following: Figures 1 to 3 The precast wall panel mold provided by this utility model will now be described. The precast wall panel mold includes a mold frame 10 and a mounting frame 20. The mold frame 10 is open on the upper side, forming a casting space inside. The mounting frame 20 spans the casting space and is connected to the mold frame 10 at both ends. The mounting frame 20 is provided with a plurality of mounting parts, which are used to install pre-embedded connectors 40.

[0026] It should be noted that the mold frame 10 is preferably made of Q235 carbon structural steel, and is composed of four side frames. The overall structure is a rectangular frame, with a side frame thickness of 8-12mm. The inner length of the frame is designed according to the length of the precast wall panel, and the inner width is designed according to the width of the wall panel. The height of the frame is consistent with the thickness of the precast wall panel. The mounting bracket 20 is made of 6061 aluminum alloy or Q235 steel, spans the pouring space along the width direction of the mold frame 10, and is fixedly connected to the mold frame 10 at both ends. The number and spacing of the mounting parts can be set as needed to accommodate the layout of the connectors 40 for different specifications of precast wall panels.

[0027] The beneficial effects of the precast wall panel mold provided in this embodiment of the present invention are as follows: Compared with the prior art, the precast wall panel mold provided in this embodiment of the present invention directly fixes the internal connecting parts 40 through the mounting frame 20, replacing the traditional welding method with the steel reinforcement skeleton, completely avoiding the high risk of welding operations, reducing the configuration requirements of special operation personnel, and reducing production costs; the mounting frame 20 is rigidly connected to the mold frame 10, forming a fixed reference independent of the steel reinforcement skeleton, avoiding the displacement of the connecting parts 40 caused by the displacement of the steel reinforcement skeleton during concrete pouring and solidification, and ensuring the positional accuracy of the connecting parts 40.

[0028] like Figure 1 and Figure 2 As shown, in a specific embodiment of the precast wall panel mold provided in this utility model, the mounting frame 20 includes a mounting plate 21 and a reinforcing rib 22. The mounting plate 21 is horizontally arranged and connected to the mold frame 10 at both ends. The reinforcing rib 22 is arranged on the upper side of the mounting plate 21, connected to the mounting plate 21, and arranged along the length direction of the mounting plate 21.

[0029] Specifically, the mounting plate 21 is made of Q235 steel plate or 6061 aluminum alloy plate with a thickness of 5-8mm. The length of the plate is consistent with the overall length of the mounting frame 20. The reinforcing rib plate 22 is made of the same material with a thickness of 4-6mm. The height is set according to actual needs. It is set along the length of the mounting plate 21 and is connected to the mounting plate 21 by fillet welding or detachable connection by bolts. Each mounting plate 21 is provided with 1-2 reinforcing rib plates 22.

[0030] It should be noted that the reinforcing rib 22 and the mounting plate 21 form a combined structure, which greatly improves the bending and torsional stiffness of the mounting frame 20 and prevents the mounting frame 20 from deforming. The horizontally set mounting plate 21 provides a stable mounting plane for the connectors 40, ensuring that all connectors 40 are at the same horizontal height and meeting the butt joint accuracy requirements when splicing wall panels. The reinforcing rib 22 is set along the length direction, which can evenly distribute the force on the mounting part and prevent local stress concentration from causing the mounting plate 21 to crack.

[0031] like Figure 1 and Figure 2 As shown, in a specific embodiment of the prefabricated wall panel mold provided in this utility model, the lower end of the reinforcing rib 22 is connected to the edge of the mounting plate 21, forming an "L" shaped frame with the mounting plate 21.

[0032] Specifically, the lower end of the reinforcing rib 22 is aligned with the edge of the mounting plate 21, and the two are connected by continuous fillet welds, with the weld length being consistent with the length of the reinforcing rib 22; the right-angled inner side of the "L"-shaped frame adopts a circular arc transition with a radius of 2-3mm to avoid stress concentration; the upper end face of the reinforcing rib 22 is perpendicular to the upper surface of the mounting plate 21 to ensure that the force direction is consistent with the bearing direction of the mounting frame 20.

[0033] It should be noted that, compared with a rectangular section, the "L" shaped cross section has better bending strength with the same amount of material, achieving a balance between lightweight and high strength, reducing the overall weight of the mounting frame by 20, and facilitating manual installation and disassembly.

[0034] The connection between the reinforcing rib 22 and the edge of the mounting plate 21 maximizes the load-bearing capacity of the mounting plate 21 in the width direction, while avoiding the reinforcing rib 22 occupying the installation space of the mounting part. The right-angled inner arc transition effectively eliminates stress concentration points and extends the service life of the mounting bracket 20.

[0035] like Figure 1 and Figure 2 As shown, in a specific embodiment of the prefabricated wall panel mold provided in this utility model, the mounting part includes a mounting hole and a fixing bolt 23. The mounting hole is opened on the mounting plate 21, and the fixing bolt 23 passes through the mounting hole and is screwed to the connector 40.

[0036] Specifically, the mounting hole is a round hole that penetrates the mounting plate 21, and the hole diameter is 0.5-1mm larger than the nominal diameter of the fixing bolt 23; the fixing bolt 23 is made of 8.8 grade high-strength carbon steel or 304 stainless steel, and the surface is hot-dip galvanized or passivated; the screw hole specification of the connector 40 matches that of the fixing bolt 23.

[0037] It should be noted that bolt connection replaces welding, which is simple to operate, does not require professional welders, greatly improves installation and disassembly efficiency, and can be reused.

[0038] The clearance fit between the mounting hole and the bolt facilitates quick alignment and installation. At the same time, the bolt head pressing against the mounting plate 21 can form a preload, further fixing the position of the connector 40 and preventing loosening. The high-strength bolt and matching bolt hole ensure the connection strength and can withstand the impact and lateral pressure during concrete pouring, preventing the connector 40 from falling off.

[0039] like Figure 1 and Figure 2 As shown, in a specific embodiment of the prefabricated wall panel mold provided in this utility model, the mounting part further includes a sealing gasket 24. The sealing gasket 24 is embedded on the lower side of the mounting plate 21 and is flush with the mounting plate 21. The mounting hole passes through the sealing gasket 24, and the sealing gasket 24 is used to seal and cooperate with the connector 40.

[0040] Specifically, the connector 40 is usually a threaded sleeve, or it consists of a connecting plate and several threaded sleeves installed on the connecting plate, and hook bars are provided on the back of the connecting plate to improve the bonding strength with concrete.

[0041] The sealing gasket 24 is made of nitrile butadiene rubber (NBR) or ethylene propylene diene monomer rubber (EPDM), which effectively resists corrosion from concrete slurry, has a thickness of 3-5 mm. A through hole with the same diameter as the mounting hole is opened at the center of the sealing gasket 24; a groove is opened at the position corresponding to the mounting hole on the lower side of the mounting plate 21, and after the sealing gasket 24 is embedded, the upper surface of the sealing gasket is flush with the lower surface of the mounting plate 21; when the connecting member 40 is screwed with the fixing bolt 23, the upper end face of the connecting member 40 is in close contact with the lower surface of the sealing gasket 24.

[0042] It should be noted that the compression sealing structure of the sealing gasket 24 can effectively block concrete slurry from entering the interior of the threaded sleeve, prevent the slurry from blocking the threaded hole after solidification, eliminate the need for post-cleaning, save working hours, and ensure that the threaded sleeve can be normally connected with other components after the wall panel is formed.

[0043] The flush design of the sealing gasket 24 and the mounting plate 21 avoids protrusions or depressions on the lower surface of the mounting plate 21, ensuring the flatness of the upper surface of the prefabricated wall panel. The sealing gasket 24 made of rubber material has certain elasticity, which can compensate for the slight height deviation of the connecting member 40 during installation, buffer the vibration during concrete pouring, and reduce the risk of loosening of the connecting member 40.

[0044] As Figure 1 and Figure 3 shown, in a specific embodiment of the prefabricated wall panel mold provided by the embodiment of the present utility model, it further comprises two clamps 30, which are arranged at both ends of the mounting frame 20 and connected with the mounting frame 20 and the mold frame 10.

[0045] Specifically, the clamp is integrally stamped or welded from Q235 steel. The overall clamp 30 is in a "U" shape or a "匚" shape, and the width of the clamping opening matches the sum of the thickness of the frame of the mold frame 10 and the thickness of the end of the mounting frame 20; the two clamps 30 are symmetrically arranged at both ends of the mounting frame 20, and the connection position with the mold frame 10 is the outer side of the upper frame of the frame.

[0046] It should be noted that the clamp 30 realizes the detachable connection between the mounting frame 20 and the mold frame 10. Compared with welding fixation, the disassembly time of the mounting frame 20 is greatly shortened, and the turnover efficiency of the mold is greatly improved.

[0047] The two clamps 30 are symmetrically stressed, ensuring consistent fixing force at both ends of the mounting frame 20 and avoiding position deviation of the connecting member 40 caused by inclination of the mounting frame 20; the clamps 30 are adaptable to mold frames 10 and mounting frames 20 of different thicknesses, can be reused across specifications, and reduce the procurement cost of mold accessories.

[0048] As Figure 1 and Figure 3As shown, in a specific embodiment of the prefabricated wall panel mold provided by the embodiment of the present utility model, the clamp 30 includes a clamping frame and an adjusting bolt 33, the clamping frame is provided with a clamping portion and an adjusting portion, the clamping portion and the adjusting portion are respectively arranged on both sides of the mounting frame 20, and the clamping portion is configured to abut against the mold frame 10; the adjusting bolt 33 passes through the adjusting portion and is screwed with the adjusting portion, and the adjusting bolt 33 is configured to abut against the mounting frame 20 to clamp and fix the mounting frame 20 onto the mold frame 10.

[0049] It should be noted that the clamping force can be accurately controlled by adjusting the screwing depth of the adjusting bolt 33, so as to avoid looseness caused by too small clamping force or deformation of the mounting frame 20 caused by too large clamping force.

[0050] The clamping portion and the adjusting portion are respectively located on both sides of the mounting frame 20, forming a two-way "clamping-pressing" fixing structure, which has better fixing stability than a single clamping manner.

[0051] As Figure 1 and Figure 3 shown, in a specific embodiment of the prefabricated wall panel mold provided by the embodiment of the present utility model, the clamping frame includes clamping plates 31 and a connecting block 32, two clamping plates 31 are arranged in parallel and at intervals, a clamping area is arranged in the middle of the clamping plates 31, and the clamping portion and the adjusting portion are located on two sides of the clamping area; the connecting block 32 is arranged between the two clamping plates 31 and is fixedly connected with the clamping plates 31 to form the adjusting portion, a threaded hole is opened on the connecting block 32, and the adjusting bolt 33 is screwed with the threaded hole.

[0052] Specifically, the clamping plate has a C-shaped structure, and a clamping area is formed in the middle portion; the connecting block 32 is made of steel plate of the same material, has the same height as the clamping plates 31, and is connected to the clamping plates 31 by full welding, a threaded hole matching the adjusting bolt 33 is opened in the center of the connecting block 32, and the axis of the threaded hole coincides with the center line of the clamping area.

[0053] It should be noted that the design of two clamping plates 31 can effectively increase the stress area compared with a single clamping plate 31, improve the clamping stability, and further improve the positioning accuracy.

[0054] The connecting block 32 connects two clamping plates 31 at the same time, which not only forms the threaded reference of the adjusting portion, but also enhances the overall stiffness of the clamping frame and prolongs the service life of the clamp 30. The spacing of the clamping area can adapt to mounting frames 20 of different thicknesses, which improves the versatility of the clamp 30 and reduces the number of special fixtures 30.

[0055] As Figure 1 and Figure 3 shown, in a specific embodiment of the prefabricated wall panel mold provided by the embodiment of the present utility model, a plurality of teeth 34 are provided on the side of the clamping portion of the clamping plate 31 facing the mold frame 10.

[0056] Specifically, the teeth 34 are integrally stamped from the clamping plate 31. The teeth 34 are triangular in shape and are evenly distributed along the length of the clamping part. The tips of the teeth 34 face the mold frame 10. Furthermore, the surface of the teeth 34 can be hardened to enhance wear resistance. When the clamping part abuts against the mold frame 10, the teeth 34 can be slightly embedded in the oxide layer on the surface of the frame (or slightly pressed into the surface of the frame) with an embedding depth of 0.1-0.3mm.

[0057] It should be noted that the tooth 34 structure greatly increases the static friction between the clamping part and the mold frame 10, completely avoiding the slippage of the clamp 30 caused by concrete pouring vibration, and ensuring that the mounting frame 20 has no displacement throughout the process; the tooth 34 is embedded in the frame surface to form a "mechanical engagement", which significantly improves the fixing reliability compared with simple planar contact, and is especially suitable for mold frames 10 with slight oil stains or oxide layers on the surface.

[0058] The tooth 34 is only 1-2mm high, which will not cause permanent damage to the surface of the mold frame 10. After disassembly, only a small indentation is left, which will not affect the subsequent use of the frame, thus balancing the fixing effect and mold protection.

[0059] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
