Description

Technical Field

[0001] This utility model belongs to the field of precast panel technology, specifically relating to a precast panel mold frame. Background Technology

[0002] With the continuous advancement of building industrialization, prefabricated assembly buildings have gradually become the mainstream construction method. Precast concrete slabs are widely used in various building structures due to their advantages such as stable molding quality and high on-site construction efficiency. In the production process of precast components, the mold frame, as a key tool in the molding stage, directly affects the geometric dimensions, edge neatness, and demolding effect of the components.

[0003] Currently, precast slab formwork typically consists of a main enclosure and secondary enclosures, forming a closed cavity for concrete pouring. In traditional formwork structures, the secondary enclosures are often of fixed length. During use, different lengths of secondary enclosures need to be replaced according to different specifications of precast slabs, resulting in a large number of spare parts, complex management, inconvenient assembly and disassembly, and low adjustment accuracy, thus affecting production efficiency and flexibility. When adjusting the cavity size, some formwork structures require complete component replacement to adapt to changes in slab dimensions, leading to cumbersome operations and high costs. Furthermore, because the secondary enclosures cannot be finely adjusted, they are prone to causing dimensional deviations in the cavity, which in turn affect the geometric accuracy of the precast slabs. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a precast panel mold frame that is flexible in structure, convenient in adjustment, and suitable for precast panels of different specifications, so as to solve the problems of frequent replacement, inconvenient adjustment and insufficient precision of existing mold frames.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A precast panel formwork includes a main enclosure panel and a secondary panel hanger. The secondary panel hanger has a secondary enclosure panel movably nested on its outer side. The secondary enclosure panel includes a large baffle, a middle baffle, and a small baffle. The large baffle, the middle baffle, and the small baffle are spliced ​​end to end to form the secondary enclosure panel. Multiple middle baffles and multiple small baffles are provided. The length of the spliced ​​secondary enclosure panel can be adjusted as needed.

[0007] Furthermore, it also includes an F-type buckle, the bottom end of which is inserted and installed on one side of the main enclosure panel, and a screw is screwed onto one side of the F-type buckle. The F-type buckle and the main enclosure panel are fixed and limited by the screw.

[0008] Furthermore, the top of the F-type buckle has a U-shaped opening, and the auxiliary plate hanger is placed inside the U-shaped opening.

[0009] Furthermore, a nut is nested on the outer side of the sub-plate hanger rod, and the nut and the sub-plate hanger rod are connected by a threaded connection, with the nut tightly attached to one side of the F-type buckle. The nut is used to fasten the main plate and the sub-plate.

[0010] Furthermore, the large baffle has grooves on both sides, the middle baffle has a groove on one side and a protrusion on the other side, and the small baffle has a groove on one side and a protrusion on the other side, with the protrusion and groove matching each other.

[0011] Furthermore, spare small baffles are nested at both ends of the auxiliary plate hanger rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model uses a secondary enclosure plate composed of a large baffle, a medium baffle, and a small baffle, spliced ​​end to end. The number of medium and small baffles is adjustable, allowing the length of the secondary enclosure plate to be precisely adjusted according to the size of the precast slab. This solves the problem that the length of the secondary enclosure plate in the existing mold frame is fixed and cannot adapt to precast slabs of different specifications. It improves the versatility and flexibility of the mold frame and reduces the frequency of mold replacement and management costs.

[0014] This utility model uses F-type buckles and screws to achieve compression and limiting fixation between the main plate and the secondary plate. The secondary plate hanger is nested in the U-shaped opening at the top of the F-type buckle, and with the tightening effect of the nut on the outside of the secondary plate hanger, a stable clamping structure is formed between the main plate and the secondary plate. This solves the problems of loose connection structure, poor locking, and easy slippage of the secondary plate in the existing mold frame, improves the stability of the mold cavity boundary, and ensures the accuracy of the precast plate forming dimensions.

[0015] This utility model, by setting up spare small baffles, pre-installs a certain number of small baffles at both ends of the auxiliary plate hanger as spare filling modules, which makes it easy to flexibly increase or decrease the splicing length on site according to needs. It solves the problem that existing mold frames need to be temporarily processed or have insufficient parts when making detailed adjustments, and improves the efficiency of on-site operation and the emergency adaptability of the mold frame system.

[0026] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0027] like Figures 1-8 As shown, a precast panel formwork includes a main enclosure 101 and a secondary enclosure hanger 102. The main enclosure 101 has a plate-like structure and is located along the long side of the overall formwork structure, serving as a main limiting component. The secondary enclosure hanger 102 is horizontally arranged along the short side of the main enclosure 101 to support and connect the secondary enclosure 103. The secondary enclosure 103 is movably nested on the outer side of the secondary enclosure hanger 102. The secondary enclosure 103 includes a large baffle 131, a middle baffle 132, and a small baffle 133. The large baffle 131 has a rectangular plate-like structure and serves as the main unit of the secondary enclosure 103 for initial construction. Modeling cavity boundary; middle baffle 132 and small baffle 133 serve as auxiliary units for fine-tuning the length according to the specific dimensions of the mold cavity; large baffle 131, middle baffle 132 and small baffle 133 are spliced ​​end to end to form sub-wall 103, with multiple middle baffles 132 and multiple small baffles 133; the spliced ​​sub-wall 103, while meeting strength requirements, has adjustable and modular characteristics, thus facilitating the adjustment of the length of the sub-wall 103 as needed, adapting to the molding requirements of precast panels of different specifications, and improving the versatility and economy of the mold frame structure.

[0028] like Figure 1 and Figure 2As shown, it also includes an F-type buckle 104; the overall structure of the F-type buckle 104 is inverted F-shaped, made of high-strength metal material, and has good corrosion resistance and structural stability; the bottom end of the F-type buckle 104 is inserted into a preset slot on one side of the main enclosure plate 101 to ensure the accuracy of its installation position; a screw 142 is screwed onto one side of the F-type buckle 104, the screw 142 passes through the threaded hole of the F-type buckle 104 and is pressed against the outer wall of the main enclosure plate 101; through the screwing action of the screw 142, a tight connection is formed between the F-type buckle 104 and the main enclosure plate 101, ensuring that the auxiliary plate hanger 102 is stable and does not fall off during the adjustment of the formwork or the pouring process; the F-type buckle 104 is easy to adjust on site and reuse, reduces the dependence on the fixed structure, and improves the ease of use.

[0029] like Figure 1 and Figure 2 As shown, the top of the F-type buckle 104 has a U-shaped opening 141; the U-shaped opening 141 has a semi-open groove structure with an anti-slip treatment on the inner surface, which is used to limit the placement of the sub-plate hanger 102; after the sub-plate hanger 102 is placed inside the U-shaped opening 141, the sub-plate hanger 102 is limited and fixed in the vertical direction through the cooperation between the U-shaped opening 141 and the screw 142; this structure ensures that the sub-plate 103 remains stable during the use of the mold frame, avoids slippage caused by vibration or external force, thereby improving the stability of the mold cavity boundary and the molding quality.

[0030] like Figure 1 , Figure 2 and Figure 4 As shown, a nut is nested on the outer side of the auxiliary plate hanger 102; the inner side of the nut has a threaded structure that mates with the thread on the surface of the auxiliary plate hanger 102; the nut and the auxiliary plate hanger 102 are connected by threaded engagement, and after tightening, it can be positioned between the main plate 101 and the F-type buckle 104 after the auxiliary plate 103 is assembled and adjusted to the target length; the nut is close to one side of the F-type buckle 104, and the axial fixation of the auxiliary plate hanger 102 and the overall stability of the auxiliary plate 103 are achieved through the tight pressure between the end face of the nut and the F-type buckle 104; this structure achieves the goal of quickly adjusting and locking the position of the plate without tools, enhancing the flexibility of the formwork and the efficiency of on-site operation.

[0031] like Figures 3-8As shown, the large baffle 131 has grooves 135 on both sides; the middle baffle 132 has a groove 135 on one side and a protrusion 136 on the other side; the small baffle 133 has a groove 135 on one side and a protrusion 136 on the other side; the protrusion 136 and the groove 135 are matched and a mortise and tenon joint structure is adopted, which realizes the quick docking and stable connection between the baffles through the mortise and tenon meshing; this structure not only ensures the splicing stability of the sub-enclosure 103, but also effectively avoids the dimensional deviation caused by assembly errors; at the same time, the mortise and tenon connection method facilitates quick disassembly and reuse, and improves the utilization rate of the mold module.

[0032] like Figures 3-8 As shown, the length of the large baffle 131 is 20cm, the length of the medium baffle 132 is 5cm, and the length of the small baffle 133 is 1cm. This arrangement is to achieve high-precision adjustment of the length of the sub-baffle 103 while maintaining the rigidity and stability of the mold frame. By changing the number of medium baffles 132 and small baffles 133 used, fine adjustments to the mold cavity size can be achieved without replacing the main structural unit. This design solves the problem of fixed length and inconvenient adjustment of the existing mold frame sub-baffles, and can adapt to the production needs of precast panels of different widths, thereby effectively reducing production costs and simplifying mold reserves and replacement processes.

[0033] like Figure 1 As shown, spare small baffles 134 are nested at both ends of the auxiliary plate hanger 102. The spare small baffles 134 have the same structure as the small baffles 133, with grooves 135 and protrusions 136. They are used as supplementary modules to be temporarily installed at the ends of the auxiliary plate 103 during the adjustment process to achieve temporary size matching or accuracy compensation. The setting of the spare small baffles 134 improves the adaptability of the mold frame structure to special size requirements, enhances the flexibility of on-site operation and the sustainability of mold use.

[0034] The working principle of this utility model is as follows:

[0035] When using it, first adjust the distance between the two main side panels 101 according to the size of the precast panels to be produced, and then adjust the distance between the two auxiliary side panels 103.

[0036] When adjusting the spacing of the sub-panel 103, first screw in and loosen the screw 142. At this time, the F-type buckle 104 will be released from the squeezing and fixing of the screw 142. Then slide and adjust the spacing of the two F-type buckles 104 on the same side to adjust the spacing of the two sub-panel hanging rods 102 and the sub-panel 103.

[0037] Next, the length of the secondary enclosure 103 is adjusted according to the size of the precast panel. The adjustment method is to change the amount of middle baffle 132 and small baffle 133 used to achieve a fine adjustment of the length of the secondary enclosure 103. After the adjustment is completed, the nuts nested on the outside of the secondary panel hanger 102 are screwed and tightened so that the two main enclosures 101 press and fix the secondary enclosure 103. Compared with the traditional secondary enclosure with a fixed length, the length of the secondary enclosure 103 in this solution can be finely adjusted, which is more economical, more applicable, and more flexible.

[0038] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
