Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1-5 This utility model provides a technical solution:

[0033] The precast ribbed concrete composite slab includes a formwork 100 and also includes:

[0034] The molding unit 1 is located on the upper end of the mold table 100 and is used to mold the poured concrete.

[0035] The demolding unit 2 includes a rib assembly 21 disposed on the upper part of the molding unit 1 for embedding into the poured concrete, and a demolding assembly 22 disposed between the rib assembly 21 and the molding unit 1 for demolding the rib assembly 21 and the concrete simultaneously.

[0036] It should be noted that when demolding the concrete pouring layer 101 in the molding unit 1, the demolding component 22 is pulled upward. The demolding component 22, in cooperation with the rib component 21, drives the rib component 21 and the concrete pouring layer 101 to move upward synchronously, so that the concrete pouring layer 101 separates from the molding unit 1, thus completing the demolding work. The entire demolding process does not require repeated installation and disassembly of the mold. The demolding process is simple and the demolding efficiency is high.

[0037] As an improvement, such as Figure 1 As shown, the molding unit 1 includes:

[0038] Multiple trapezoidal strips 11 are provided and fixedly connected at equal intervals to the upper end of the mold table 100. Adjacent trapezoidal strips 11 form a forming groove 12, which is in the shape of an inverted trapezoid.

[0039] Furthermore, such as Figures 1-3 , Figure 5 As shown, the rib assembly 21 includes:

[0040] The bottom rod 211 is placed inside the forming groove 12;

[0041] Left rib 212 and right rib 213 are fixedly connected to the upper end of the bottom rod 211 and are used to be embedded into the concrete poured in the molding groove 12.

[0042] Furthermore, the left rib 212, bottom rod 211, and right rib 213 are connected in sequence to form a V-shape with a gradually expanding upper opening, which is used to cooperate with the demolding component 22 to demold the concrete and the rib component 21 simultaneously.

[0043] Among them, such as Figure 4 As shown, the demolding assembly 22 includes:

[0044] The bracket 223 is provided in two sets, which are placed parallel to each other on the upper end of the corresponding two sets of support blocks 224. The upper end of the bracket 223 is threadedly connected to the mold table 100 by screws passing through the support blocks 224.

[0045] Support blocks 224 are fixedly connected to the lower two ends of bracket 223 and are used to support bracket 223 above mold table 100;

[0046] At least two sets of support rods 221 are provided, which are fastened to the upper end of the bracket 223 by screws and are perpendicular to the bracket 223.

[0047] The top shaft 222 is provided in multiple sets and is mounted on the upper end of the support rod 221.

[0048] Furthermore, the top shaft 222 corresponds one-to-one with the left rib 212 and the right rib 213, and the distance between adjacent top shafts 222 is smaller than the distance between the upper openings of the left rib 212 and the right rib 213.

[0049] As an improvement, such as Figure 4 As shown, the upper end of the support rod 221 is provided with multiple sets of limiting grooves 2211 for limiting the top shaft 222, and the limiting grooves 2211 correspond one-to-one with the top shaft 222.

[0050] It should be added that the molding groove 12 in this utility model is coated with a release agent before pouring concrete, which facilitates the separation of the subsequent concrete molding parts from the molding groove 12.

[0051] It should be noted that: such as Figures 1-5 As shown, in the specific implementation process of this utility model, before pouring concrete into the forming groove 12, the bottom rods 211, which are welded with left ribs 212 and right ribs 213 on the upper part, are placed in the corresponding forming grooves 12. The two sets of brackets 223 are supported on the mold table 100 by support blocks 224 and the support blocks 224 are fastened to the mold table 100 by screws, so that the two sets of brackets 223 are parallel to each other. Then, multiple support rods 221 are fastened to the upper ends of the two sets of brackets 223 by screws. Finally, the top shaft 222 is placed in the corresponding limiting groove 2211, so that the left rib is located in the limiting groove 2211. 212. The spacing of the top shafts 222 on the side of the right rib 213 is smaller than the upper opening of the left rib 212 and the right rib 213. At this time, the top shafts 222 support the left rib 212 and the right rib 213, so that the left rib 212, the right rib 213 and the bottom rod 211 form a V shape with the opening pointing directly upward. Then, concrete is poured into the molding groove 12 so that the concrete pouring layer 101 submerges the bottom rod 211 as a whole and the lower part of the left rib 212 and the right rib 213, ensuring that the inside of the molded concrete part can have ribs, which improves the bending and shear resistance of the concrete part.

[0052] like Figures 1-3 As shown, when demolding the concrete molded part, steel wire ropes are attached to both ends of each support 223, and the other end of the steel wire ropes is hung on the hook of the crane. The crane is started, and the crane drives the support 223 to move upward through the steel wire ropes. The support 223 drives the top shaft 222 to move upward through the support rod 221. The top shaft 222 drives the left rib 212 and the right rib 213 to move upward through the bottom rod 211. The left rib 212 and the right rib 213 drive the molded concrete pouring layer 101 to move upward through the bottom rod 211, so that the concrete pouring layer 101 separates from the molding groove 12, and the demolding work is completed. The whole demolding process is simple and does not require repeated installation and disassembly of the trapezoidal strip 11, and the work efficiency is high.

[0053] In addition, by setting the trapezoidal strips 11 to a V shape, the gap between adjacent trapezoidal strips 11 is an inverted trapezoidal shape. This design reduces the resistance to demolding of the subsequent concrete pouring layer 101 and reduces the difficulty of demolding.
