[0033] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0034] As mentioned in the background section, prestressed concrete precast beams are widely used in the construction of various large factories, logistics warehouses, production workshops, and large-span, open-plan buildings. In the existing prestressed beam forming process, the distance between two adjacent side molds is adjusted synchronously by screw nuts and requires the use of a crane, which results in problems such as small working space, high safety risks, low work efficiency, and poor product compatibility.

[0035] Please refer to Figure 1 The prestressed beam mold 100 provided in the embodiments of this utility model can solve the above problems, and will be described in detail below.

[0036] The prestressed beam mold 100 includes a mold platform 110, side mold components 120, movable components 130, and guide components 140. The side mold component 120 includes a middle side mold 121 and an edge side mold 122, both of which are located on the upper side of the mold platform 110. One of the movable component 130 and the guide component 140 is disposed on the mold platform 110, and the other is disposed on the middle side mold 121 and / or the edge side mold 122. The movable component 130 cooperates with the guide component 140.

[0037] During operation, the movable part 130 and the guide part 140 can work together to move the middle side mold 121 or the side mold 122 relative to the mold table 110, thereby adjusting the distance between the middle side mold 121 and the side mold 122. Compared with the existing technology, this expands the working space, reduces safety risks, and improves work efficiency and product compatibility.

[0038] It should be noted that the movable part 130 or the guide part 140 can be provided only in one of the middle side mold 121 and the side mold 122, or can be provided in both, thereby improving the flexibility of adjusting the distance between the middle side mold 121 and the side mold 122.

[0039] Furthermore, to prevent relative slippage during the molding process, the intermediate side mold 121 and the edge side mold 122 can be locked using a locking mechanism after they reach the appropriate positions before concrete pouring. Specifically, bottom and side locking methods can be used for secure installation, thereby reducing the risk of deformation and grout leakage, and thus improving product quality.

[0040] Furthermore, the intermediate side mold 121 and the side mold 122 can be designed with height-enhancing fixtures to facilitate the production of prestressed beams of different heights.

[0041] In this embodiment, there are four intermediate side molds 121 and two side molds 122, with the four intermediate side molds 121 disposed between the two side molds 122. Of course, in other embodiments of this utility model, the number of intermediate side molds 121 can also be two, six, eight, etc., and there is no limitation on the specific number.

[0042] In this embodiment, the guide member 140 is a guide rail, which is set on the top of the mold table 110. The extension direction of the guide rail is consistent with the arrangement direction of the middle side mold 121 and the side mold 122. The movable member 130 is a roller, which is set at the bottom of both the middle side mold 121 and the side mold 122. The roller cooperates with the guide rail.

[0043] Of course, in other embodiments of this utility model, the movable part 130 can also be a slider, which slides in conjunction with the guide rail. The sliding resistance between the two can be reduced by applying lubricating oil. Furthermore, the guide rail can also be set at the bottom of the middle side mold 121 and the side mold 122, while the slider or roller is set on the mold table 110. The specific arrangement is not limited.

[0044] Please refer to Figure 1 and Figure 2 The prestressed beam mold 100 also includes a mounting bracket 150. The middle side mold 121 has a cuboid structure. The bottom of the middle side mold 121 and the bottom of the side mold 122 are both connected to rollers through the mounting bracket 150. By setting the mounting bracket 150, the connection stability of the rollers can be improved.

[0045] In this embodiment, the extending direction of the mounting bracket 150 is consistent with the extending direction of the guide rail, and the extending length of the mounting bracket 150 is greater than the extending length of the bottom of the intermediate side mold 121 and / or the side mold 122. Furthermore, a single mounting bracket 150 may be connected to at least two rollers.

[0046] Of course, in other embodiments of this utility model, the extending direction of the mounting bracket 150 may be perpendicular to the extending direction of the guide rail, or the mounting bracket 150 may be a rectangular ring structure with two sides aligned with the extending direction of the guide rail and the other two sides perpendicular to the extending direction of the guide rail.

[0047] In addition, the middle side mold 121 can be made into a convex shape, and the rollers can be directly connected to the bottom of the middle side mold 121.

[0048] Please refer to Figure 1 and Figure 3 To improve the stability of the side mold 122, the side mold 122 can be made into a trapezoidal structure that is smaller at the top and larger at the bottom. Specifically, a vertical surface 1221 is formed on the side of the side mold 122 that is close to the middle side mold 121, and an inclined surface 1222 is formed on the side of the side mold 122 that is away from the middle side mold 121, thereby preventing the side mold 122 from tilting in the direction away from the middle side mold 121.

[0049] Furthermore, in order to facilitate the application of force to pull the side mold 122, a handle can be provided on the side mold 122, and the handle can be installed on the inclined surface 1222.

[0050] It is worth noting that the vertical surface 1221 is set perpendicularly to the top surface of the mold table 110 and parallel to the plate surface of the middle side mold 121, while the inclined surface 1222 is set inclined to both the top surface of the mold table 110 and the plate surface of the middle side mold 121.

[0051] Please refer to Figure 1 and Figure 3 The prestressed beam mold 100 also includes a bottom mold 160, which is detachably connected to the mold table 110. This detachable connection allows for easy replacement of the bottom mold 160 as needed, thereby improving the overall product compatibility of the prestressed beam mold 100.

[0052] When there are at least two intermediate side molds 121, bottom mold members 160 can be provided between two adjacent intermediate side molds 121 and between adjacent intermediate side molds 121 and side molds 122. Furthermore, the distance between two adjacent bottom mold members 160 can be greater than the width of the intermediate side molds 121.

[0053] It should be noted that when the bottom of the middle side mold 121 and the side mold 122 is connected to the mounting bracket 150, the end of the mounting bracket 150 can extend into the interior of the bottom mold part 160 in the mold-closed state, thereby preventing the bottom mold part 160 from tipping over. Furthermore, the bottom mold part 160 can accommodate widths from 250mm to 600mm, thus improving the ease of mold changeover.

[0054] Furthermore, when there are multiple bottom formwork components 160, on the one hand, at least two of them can have different widths; on the other hand, bottom formwork components 160 at the same position can be replaced with bottom formwork components 160 of different widths through detachable connection, thereby ultimately forming precast beams of different widths.

[0055] Please refer to Figure 3 The prestressed beam mold 100 also includes a cover plate 170, and the number of intermediate side molds 121 is at least two. The cover plate 170 is disposed on the upper side of every two adjacent intermediate side molds 121 or on the upper side of adjacent intermediate side molds 121 and side molds 122.

[0056] During the process of forming the prestressed beam using the prestressed beam mold 100, workers usually stand on the middle side mold 121 to carry out the pouring operation. By setting the cover plate 170, the support for the workers can be increased and the standing range of the workers can be expanded, thereby reducing the risk of workers falling.

[0057] In summary, the prestressed beam mold 100 provided by the embodiments of this utility model has at least the following advantages:

[0058] (1) The prestressed beam mold 100 can make the middle side mold 121 and the side mold 122 both push-pull moving structures through the cooperation of the movable part 130 and the guide part 140. When disassembling and assembling the mold, there is no need to use a crane, thereby reducing safety hazards and improving work efficiency.

[0059] (2) The prestressed beam mold 100 can reduce the resistance of relative movement as much as possible through the cooperation of rollers and guide rails, thereby improving the movement efficiency.

[0060] (3) The prestressed beam mold 100 is designed with the side mold 122 as a trapezoidal structure with a smaller top and a larger bottom, and the side of the side mold 122 close to the middle side mold 121 is a vertical surface 1221, while the side away from the middle side mold 121 is an inclined surface 1222. This improves the structural stability of the side mold 122 while ensuring the shape of the prestressed beam, and prevents the side surface 122 from tilting away from the middle side mold 121.

[0061] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
