Description

Technical Field

[0001] This utility model relates to the field of mold manufacturing technology, specifically a mold for manufacturing prefabricated composite slabs. Background Technology

[0002] Precast composite slabs are concrete floor slabs composed of precast and cast-in-place components, and are one of the commonly used components in prefabricated buildings. They combine factory-produced precast components with on-site cast-in-place concrete, possessing the advantages of high production efficiency and quality control of precast components and the good integrity of cast-in-place structures.

[0003] When producing precast composite slabs, special molds need to be made according to the size and shape requirements of the composite slabs. Then, a steel reinforcement skeleton is tied inside the mold, a release agent is sprayed, and then concrete is poured. After the concrete solidifies, the demolding operation can be carried out. The precast composite slabs after demolding are inspected for appearance quality, dimensional deviation, and thickness of the steel reinforcement protective layer. Only qualified products can be shipped out of the factory.

[0004] Patent CN215319421U discloses a universal mold for manufacturing precast composite slabs, including a bottom mold, a top mold, a magnetic box, a fixing fixture, and a high-strength bolt assembly. The lower edge of the magnetic box is recessed inward to form a notch. The fixing fixture includes a base plate and a top plate. The base plate has a U-shaped pre-drilled hole and is welded to the top plate. The high-strength bolt assembly is placed in the pre-drilled hole and used to fix the fixing fixture to the upper part of the magnetic box. This device has a reasonable structure, ingenious design, convenient operation, energy saving and emission reduction, standardized components, and can be mass-produced. It has a high product qualification rate, improves enterprise efficiency, and has a good market prospect and development space compared to existing technologies.

[0005] However, the above-mentioned mold still has the following problems:

[0006] When tying the steel reinforcement skeleton inside the mold, workers need to stand or squat inside the mold to operate. The steel reinforcement laid inside the mold is crisscrossed, which restricts the workers' range of movement and may also trip them, causing them to fall and get injured. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a mold for manufacturing precast composite slabs, which facilitates workers in tying the steel reinforcement framework.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a mold for manufacturing precast composite slabs, comprising a mold body, a support plate mounted on the surface of the mold body, a plurality of support rods fixedly connected to the bottom surface of the support plate, and a support seat fixedly connected to the bottom end of each support rod, the support seat being in contact with the bottom surface inside the mold body.

[0009] Furthermore, each of the support bases is detachably connected to a magnet at its bottom.

[0010] Furthermore, the bottom of the support base is provided with a movable groove for raising and lowering the magnet, a connecting rod is fixedly connected to the surface of the magnet, a sliding groove corresponding to the position of the connecting rod is provided inside the support rod, a guide ball is embedded in the inner wall of the sliding groove, an oblique guide groove corresponding to the position of the guide ball is provided on the outer wall of the connecting rod, and a handle is installed on the top of the connecting rod.

[0011] Furthermore, the outer wall of the connecting rod is provided with an installation groove that communicates with the top of the inclined guide groove, the top of the connecting rod is provided with a threaded groove, a stud is threadedly connected in the threaded groove, a handle is fixedly connected to the top of the stud, and the bottom surface of the handle is in contact with the surface of the support plate.

[0012] Furthermore, a silicone pad is fixedly connected to the surface of the support plate.

[0013] Furthermore, multiple anti-slip strips are fixedly connected to the surface of the silicone pad.

[0014] Furthermore, all corners of the support plate are rounded.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This invention installs a support plate on the mold body, which separates the worker's feet from the steel reinforcement frame, avoiding the difficulty of moving between the steel reinforcements and finding a foothold. The support plate provides a relatively flat and stable operating platform, allowing the worker to move and turn more freely, greatly reducing physical fatigue, improving the speed and quality of the binding operation, and reducing the risk of workers being scratched or punctured by the steel reinforcement.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] like Figures 1 to 5 As shown, a mold for manufacturing precast composite slabs includes a mold body 1, a support plate 2 is installed on the surface of the mold body 1, a plurality of support rods 3 are fixedly connected to the bottom surface of the support plate 2, and a support seat 4 is fixedly connected to the bottom end of each support rod 3, and the support seat 4 is in contact with the bottom surface inside the mold body 1.

[0025] like Figure 1 As shown, the mold for manufacturing precast composite slabs in this utility model is similar in structure to existing molds, such as the universal mold for manufacturing precast composite slabs disclosed in patent publication number CN215319421U. The main improvement of this utility model is that it facilitates the binding of the reinforcing steel frame by workers. Figures 1 to 5 As shown, when using the mold for making precast composite slabs, if the worker needs to tie the steel reinforcement skeleton inside the mold body 1, the worker aligns the support base 4 with the gap in the steel reinforcement skeleton, and then places the support plate 2 inside the mold body 1. At this time, under the support of the support rod 3, the support plate 2 will be above the steel reinforcement skeleton, and then the worker can step on the support plate 2 to tie the steel reinforcement skeleton.

[0026] By installing a support plate 2 on the mold body 1, the worker's feet are separated from the steel reinforcement frame, avoiding the difficulty of moving between the steel reinforcements and finding a foothold. The support plate 2 provides a relatively flat and stable operating platform, allowing the worker to move and turn more freely, greatly reducing physical fatigue, improving the speed and quality of the binding operation, and reducing the risk of the worker being scratched or punctured by the steel reinforcement.

[0027] like Figure 3 and Figure 4 As shown, each support base 4 has a magnet 6 detachably connected to its bottom.

[0028] Specifically, magnet 6 can be attracted to the metal plate at the bottom of the mold body 1, thereby providing fixation for the support base 4. The use of magnet 6 can improve the stability of the support plate 2, ensuring that the support plate 2 will not slip when the staff steps on it, greatly reducing the risk of staff injury due to falls, creating a safe and reliable operating environment for the staff, and protecting the staff's life safety and health.

[0029] like Figures 3 to 5 As shown, the bottom of the support base 4 is provided with a movable groove 5 for the lifting and lowering of the magnet 6. A connecting rod 8 is fixedly connected to the surface of the magnet 6. A sliding groove 7 corresponding to the position of the connecting rod 8 is provided inside the support rod 3. A guide ball 11 is embedded in the inner wall of the sliding groove 7. An oblique guide groove 10 corresponding to the position of the guide ball 11 is provided on the outer wall of the connecting rod 8. A handle 9 is installed on the top of the connecting rod 8.

[0030] Specifically, when it is necessary to remove or change the position of the support plate 2, the operator can rotate the handle 9 to rotate the connecting rod 8. At this time, under the guidance of the guide ball 11 and the inclined guide groove 10, the connecting rod 8 will rise while rotating, thereby driving the magnet 6 to rotate and rise, so that the magnet 6 is separated from the mold body 1, and the support plate 2 can be picked up and its position changed. Through the guiding action of the guide ball 11 and the inclined guide groove 10, the connecting rod 8 rises smoothly while rotating, driving the magnet 6 to rotate and rise to separate, thus achieving the smooth separation of the magnet 6.

[0031] like Figure 3 and Figure 4 As shown, the outer wall of the connecting rod 8 is provided with an installation groove 12 that communicates with the top of the inclined guide groove 10. The top of the connecting rod 8 is provided with a threaded groove 13. A stud 14 is threadedly connected to the threaded groove 13. A handle 9 is fixedly connected to the top of the stud 14. The bottom surface of the handle 9 is in contact with the surface of the support plate 2.

[0032] Specifically, during assembly, the worker inserts the magnet 6 and the connecting rod 8 into the slide groove 7 from the bottom. At this time, the guide ball 11 will first enter the mounting groove 12, and then enter the inclined guide groove 10 from the mounting groove 12. Then, the worker rotates the handle 9 to screw the stud 14 into the threaded groove 13. After completing the installation of the four studs 14 in sequence, the assembly of the entire support structure can be completed.

[0033] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, a silicone pad 15 is fixedly connected to the surface of the support plate 2.

[0034] Specifically, during the fabrication of precast composite slabs, workers need to spend extended periods on the support slab 2 performing tasks such as tying the reinforcing steel frame. The silicone pad 15 fixed to the surface of the support slab 2 has excellent softness and elasticity. When workers step on or kneel on the support slab 2, the silicone pad 15 acts as a cushion, reducing pressure on their feet and legs, alleviating fatigue from prolonged standing or squatting. The silicone pad 15 also increases friction between the pad and the worker's shoes, ensuring worker safety on the support slab 2, reducing the risk of slipping and injury, and creating a safe working environment for the workers.

[0035] like Figures 1 to 3 As shown, multiple anti-slip strips 16 are fixedly connected to the surface of the silicone pad 15.

[0036] Specifically, the anti-slip strip 16 greatly increases the roughness and friction of the silicone pad 15 surface. The raised structure of the anti-slip strip 16 can effectively embed into the pattern of the worker's shoe sole, forming stronger grip and further reducing personnel injuries and production interruptions caused by accidents.

[0037] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the corners of the support plate are rounded.

[0038] Specifically, if the two corners of the support plate are right angles, when workers accidentally bump into the corners, the right angles will cause a large impact force on the human body, which can easily cause abrasions, cuts or even more serious impact injuries. However, if the two corners of the support plate are set to rounded corners, when workers' bodies or clothing collide with them, the rounded corners can play a buffering role, disperse the impact force generated by the collision, greatly reduce the risk of injury, and create a safer working environment for workers.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
