Description

Technical Field

[0001] This invention relates to the field of composite slabs for building floor roofing, specifically a prefabricated high-strength prestressed composite slab for building floor roofing. Background Technology

[0002] Composite floor slabs are prefabricated monolithic floor slabs composed of precast slabs and cast-in-place reinforced concrete layers. The precast slabs are both a component of the floor slab structure and a permanent formwork for the cast-in-place reinforced concrete composite layer, which can accommodate horizontal equipment pipelines. Composite floor slabs offer good overall integrity and rigidity, save on formwork, and have smooth upper and lower surfaces, facilitating finishing. They are suitable for high-rise buildings and large-span buildings requiring high overall rigidity. They can also be called reinforced concrete floor slabs and are the most widely used type of floor slab in my country due to their ease of industrial production. With the building energy efficiency standard increasing from 50% to 65%, the heat transfer coefficient K of the floor slabs in the building envelope has also been included in the mandatory clauses. Therefore, energy-saving design and construction of floor slabs are imperative. At the same time, with the promulgation and implementation of the national Ministry of Housing and Urban-Rural Development industry standard "Technical Specification for Prefabricated Concrete Structures" JGJ1-2014, the industrialization of buildings will develop rapidly. Among them, prefabricated reinforced concrete composite floor slabs, which combine the advantages of cast-in-place and prefabricated construction, save formwork, reduce project costs, and ensure the integrity and seismic resistance of the floor slab, are increasingly being used in modern civil engineering.

[0003] The current composite slabs used in the market are structured as follows: multiple reinforcing bars are fixed together using bolts or wires. Once the reinforcing bars form a rectangular frame, cement is poured into the frame with the help of a mold. Then, a vibrator is used to complete the final step of composite slab production. This production method requires three to four workers to quickly complete the frame construction of a single-sided composite slab, increasing production costs. In addition, the traditional connection method is labor-intensive in actual operation, resulting in low frame construction efficiency and affecting the production of composite slabs. Summary of the Invention

[0004] The present invention aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted in this invention is as follows:

[0006] A prefabricated high-strength prestressed composite slab for building floor slab pouring includes a molding module, an assembly module, a connecting module, and a disassembly module. The molding module includes two first templates and second templates respectively installed on the outside of the two first templates. The assembly module includes a first reinforcing bar inserted into the first template, a round rod fixed to the first reinforcing bar, a first rotating plate movably sleeved on the outside of the round rod and symmetrical about the round rod, a rod body installed on the top of the first rotating plate, a second rotating plate connecting the first rotating plate and the rod body, a limiting post installed on the top of the rod body, and a second reinforcing bar connected to the limiting post. The connecting module includes a disc movably connected to the second template, a support rod connected to the disc, a plate body movably sleeved on the outside of the support rod, a limiting hook installed on the top of the plate body, and multiple sets of positioning components connected to the connecting module. The disassembly module includes an extrusion member installed inside the first template and symmetrical about the vertical center line of the first template, a rotating shaft connected to the extrusion member, and multiple handles surrounding the top of the rotating shaft.

[0007] By adopting the above technical solution, the worker rotates the support rod, which, guided by the disc, drives the plate to make a circular motion. During this process, the plate first pushes up multiple second ribs. Then, the second ribs leave the arc-shaped opening but remain within the limiting post. Then, the limiting hook on the plate collides with the second ribs and moves them along with the second ribs until the support rod moves to the top of the vertical plate. Then, the insert rod is inserted into the second template, and the vertical plate limits the support rod. The second and first ribs are fixed. The operation is simple, reduces the labor intensity of workers, and improves the production efficiency of the composite plate.

[0008] In a preferred embodiment, the present invention can be further configured such that: there are multiple first ribs, and the multiple first ribs are all located between two second templates.

[0009] By adopting the above technical solution, the first rib is set as multiple ribs that can fill the space formed between the first template and the second template, laying the foundation for forming a solid frame.

[0010] In a preferred embodiment, the present invention can be further configured such that: multiple round rods are provided, and the multiple round rods are respectively installed on the top of multiple first reinforcing bars in groups of three; the number of rod bodies is equal to the number of round rods, and the rod bodies are coaxial with the round rods.

[0011] By adopting the above technical solution, the round rod limits the first rotating plate and provides conditions for the formation of the small rectangular groove between the first and second rotating plates. With this structural design, the structure is clear and the layout is reasonable.

[0012] In a preferred embodiment, the present invention can be further configured such that: a slide rail suitable for sliding of the rod is provided on the second rib, the top of the rod and the top of the second rib are located on the same horizontal plane, the bottom of the limiting post is in contact with the top of the second rib, and the radius of the limiting post is greater than the radius of the rod.

[0013] By adopting the above technical solution, a slide is set up to provide space for the rod to move, ensuring that the first and second rotating plates can form a small rectangular groove, and the limiting post limits the rod, making the rod move more stable and smooth.

[0014] In a preferred embodiment, the present invention can be further configured such that: four disks are provided, the four disks are located outside the two second templates in pairs, and the disks are located inside the plate.

[0015] By adopting the above technical solution, the structural layout can firmly support the plate, and at the same time, enable the plate to make stable circular motion, thus ensuring the propulsion of the second rib.

[0016] In a preferred embodiment, the present invention can be further configured such that: the support rod extends movably through the plate, and a ring is threadedly connected to the outer side of the support rod, with the outer wall of the ring in contact with the outer wall of the plate.

[0017] By adopting the above technical solution, the support rod extending to the outer end of the plate body makes it convenient for workers to rotate the plate body. Workers can drive the plate body to rotate by rotating the support rod, which is convenient to use. In addition, the ring body limits the plate body, making the plate body more stable.

[0018] In a preferred embodiment, the present invention can be further configured such that each of the multiple positioning components consists of a vertical plate and two insert rods, the vertical plate being movably sleeved on the outside of the support rod, and the insert rods being fixedly connected to the vertical plate and movably penetrating through the second template.

[0019] By adopting the above technical solution, the vertical plate is located on the outside of the plate body, which will not affect the movement of the support rod. After the support rod moves to the top of the vertical plate, the insert rod is inserted into the second template, thereby completing the limitation of the vertical plate and preventing the support rod from rotating on its own.

[0020] In a preferred embodiment, the present invention may be further configured such that: the top of the second template has a plurality of arc-shaped openings suitable for engaging the second ribs, and the number of the second ribs is half the number of the arc-shaped openings.

[0021] By adopting the above technical solution, although the number of second ribs is less than that of first ribs, they can firmly fix multiple first ribs. This structural design reduces production costs.

[0022] In a preferred embodiment, the present invention can be further configured such that: the first template has an installation groove suitable for installing the extruder, the rotating shaft extends through the top of the first template, and the handle is located at the top of the second template.

[0023] By adopting the above technical solution, the installation slot can provide space for the installation and movement of the extruded parts, ensuring that the disassembly operation can be carried out smoothly.

[0024] By adopting the above technical solution, the beneficial effects achieved by the present invention are as follows:

[0025] 1. In this invention, the worker rotates the support rod, which, guided by the disc, drives the plate to make a circular motion. During this process, the plate first lifts multiple second ribs upwards. Then, the second ribs leave the arc-shaped opening but remain within the limiting post. Then, the limiting hook on the plate collides with the second ribs and moves them along with the second ribs until the support rod moves to the top of the vertical plate. Then, the insert rod is inserted into the second template, and the vertical plate limits the support rod. The second ribs and the first ribs are fixed. The operation is simple, reduces the labor intensity of workers, and improves the production efficiency of the composite plate.

[0026] 2. In this invention, the second reinforcing bar pushed by the limiting hook drives the rod to slide through the limiting post. The rod pulls the second rotating plate, forming a small rectangular frame between the second rotating plate and the first rotating plate, thereby completing the construction of the basic frame. Then, cement is poured into the basic frame until the composite plate is formed. The structure is reasonable, the layout is regular, and the firmness and strength are guaranteed.

[0027] 3. In this invention, rotating the handle causes the extruder to rotate via a rotating shaft, and the extruder separates the second template from the first template, thereby completing the disassembly of the first and second templates. The structure is simple and the operation is convenient. Attached Figure Description

[0041] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0042] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the invention.

[0043] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a prefabricated high-strength prestressed composite slab for building floor roofing.

[0044] Example 1:

[0045] Combination Figure 1-8 As shown, the present invention provides a prefabricated high-strength prestressed composite slab for building floor casting, comprising a forming module 100, an erection module 200, a connecting module 300, and a disassembly module 400. The forming module 100 includes two first templates 110 and second templates 120 respectively installed on the outside of the two first templates 110. With the help of the first templates 110 and the second templates 120, they are the primary conditions for the forming and casting of the composite slab. During the production of the composite slab, the first templates 110 provide support for the erection module 200, while the second templates 120 provide support for the connecting module 300, enabling the connecting template 300 to be put into normal use and to achieve the function of fixing the second reinforcing bar 270.

[0046] The assembly module 200 includes a first rib 210 that is plugged into the first template 110, providing support for the round rod 220; a round rod 220 fixedly connected to the first rib 210, providing support for the first rotating plate 230 to prevent the first rotating plate 230 from spreading out; a first rotating plate 230 movably sleeved on the outside of the round rod 220 and symmetrical about the round rod 220; the first rotating plate 230 and the second rotating plate 250 cooperate to form a rectangular groove, accelerating the forming speed of the basic frame during the production of the composite board; in addition, the rectangular shape design makes the frame structure stable and reduces the probability of damage to the composite board after forming; and a rod 240 installed on the top of the first rotating plate 230, providing support for the second rotating plate 250, and simultaneously allowing the first rotating plate 250 to be pulled through by the rod 240. The frame is powered by a second rotating plate 250 connected between the first rotating plate 230 and the rod 240, a limiting post 260 installed on the top of the rod 240, and a second reinforcing bar 270 connected to the limiting post 260. The limiting post 260 allows the rod 240 to slide smoothly along the slide, improving the stability of the structure. During use, the disc 310 drives the plate 330, which is equipped with a limiting hook 340, to rotate. Then, the limiting hook 340 pushes the second reinforcing bar 270. The second reinforcing bar 270 drives the rod 240 to slide through the limiting post 260. The rod 240 pulls on the second rotating plate 250, forming a small rectangular frame between the second rotating plate 250 and the first rotating plate 230, thus completing the construction of the basic frame. Cement is then poured into the basic frame until the composite slab is formed. The structure is reasonable, the layout is regular, and the strength is guaranteed.

[0047] The connecting module 300 includes a disc 310 movably connected to the second template 120, which allows the plate 330 to move in a circular motion, thus moving the second rib 270; a support rod 320 connected to the disc 310, which provides support for the plate 330; a rotating support rod 320 that rotates the plate 330, thereby fixing the second rib 270; a plate 330 movably sleeved on the outside of the support rod 320; a limiting hook 340 installed on the top of the plate 330; and multiple positioning components 35 connected to the connecting module 300. The plate 330 and the limiting hook 340 work together to push the second rib 270 until... After the first rotating plate 230 and the second rotating plate 250 form a rectangle, the plate body 330 is fixed by the positioning component 350, thereby completing the connection of the first rib 210 and the second rib 270. During use, the worker rotates the support rod 320, which drives the plate body 330 to make a circular motion under the guidance of the disc 310. During this process, the plate body 330 first lifts up multiple second ribs 270, and then the limiting hook 340 on the plate body 330 collides with the second ribs 270 and moves them along with the second ribs 270 until the support rod 320 moves to the top of the vertical plate 351. Then, the insertion rod 352 is inserted into the second template 120, and then the vertical plate 351 limits the support rod 320, thus fixing the second ribs 270 and the first rib 210.

[0048] The disassembly module 400 includes an extruder 410 installed inside the first template 110 and symmetrical about the vertical center line of the first template 110, a rotating shaft 420 connected to the extruder 410, and a plurality of handles 430 surrounding the top of the rotating shaft 420. The handles 430 make it convenient for the user to rotate the rotating shaft 420, improving the comfort of use. During use, by rotating the handles 430, the rotating shaft 420 with the extruder 410 installed is rotated, the extruder 410 abuts against the second template 120, and then the second template 120 separates from the first template 110.

[0049] Specifically, there are multiple first ribs 210, and each of the multiple first ribs 210 is located between two second templates 120. The multiple first ribs 210 can fill the space formed between the first template 110 and the second template 120, laying the foundation for forming a solid frame.

[0050] Furthermore, multiple round rods 220 are provided, and the multiple round rods 220 are installed on the top of multiple first ribs 210 in groups of three. The number of rod bodies 240 is equal to that of the round rods 220. The rod bodies 240 are coaxial with the round rods 220. With this structural design, the installation is simple, the structure is clear, and the layout is reasonable.

[0051] Furthermore, the second rib 270 is provided with a slide rail suitable for the sliding of the rod 240. The top of the rod 240 and the top of the second rib 270 are located on the same horizontal plane. The bottom of the limiting post 260 is in contact with the top of the second rib 270. The radius of the limiting post 260 is larger than the radius of the rod 240. The slide rail provides space for the rod 240 to move, ensuring that the first rotating plate 230 and the second rotating plate 250 can form a small rectangular groove. The limiting post 260 limits the rod 240, making the movement of the rod 240 more stable and smooth.

[0052] Furthermore, four discs 310 are provided, with two discs 310 located on the outside of the two second templates 120 respectively. The discs 310 are located on the inside of the plate 330. This structural layout can firmly support the plate 330 and at the same time enable the plate 330 to make stable circular motion, thus ensuring the pushing of the second rib 270.

[0053] Furthermore, the support rod 320 movably penetrates the plate 330, and a ring is threadedly connected to the outer side of the support rod 320. The outer wall of the ring contacts the outer wall of the plate 330. The support rod 320 extending to the outer end of the plate 330 facilitates the worker's rotation of the plate 330. The worker can drive the plate 330 to rotate by rotating the support rod 320, which is convenient to use. In addition, the ring limits the plate 330, making the plate 330 more stable.

[0054] Furthermore, the top of the second template 120 has multiple arc-shaped openings suitable for engaging the second ribs 270. The number of the second ribs 270 is half the number of the arc-shaped openings. Although the number of the second ribs 270 is less than that of the first ribs 210, it can firmly fix multiple first ribs 210. This structural design reduces production costs.

[0055] Example 2:

[0056] Combination Figure 1-4 and Figure 6 As shown, based on Embodiment 1, each of the multiple positioning components 350 consists of a vertical plate 351 and two insert rods 352. The vertical plate 351 is movably sleeved on the outside of the support rod 320. The insert rods 352 are fixedly connected to the vertical plate 351 and movably pass through the second template 120. In the initial state, the vertical plate 351 is located outside the plate 330 and will not affect the movement of the support rod 320. Until the support rod 320 moves to the top of the vertical plate 351, the insert rods 352 are inserted into the second template 120, thereby completing the limitation of the vertical plate 351 and preventing the support rod 320 from rotating on its own.

[0057] Example 3:

[0058] Combination Figure 1 , 2 As shown in 3, 4, 6, 7 and 8, in the above embodiments, the first template 110 has an installation groove inside suitable for the installation of the extrusion component 410, the rotating shaft 420 moves through the top of the first template 110, and the handle 430 is located at the top of the second template 120. The installation groove can provide space for the extrusion component 410 to be installed and moved, ensuring that the disassembly operation can be carried out smoothly.

[0059] The working principle and usage process of this invention: When this invention is put into actual use, firstly, multiple first ribs 210 and second ribs 270 are respectively inserted through two first templates 110. Then, the second template 120 is inserted into the first template 110, thereby forming a large rectangular space. Then, the second ribs 270 are placed on top of multiple limiting posts 260. At this time, the angle between the two first rotating plates 230 and the two second rotating plates 250 is greater than 150 degrees. Then, the worker rotates the handle support rod 320. Under the guidance of the disc 310, the support rod 320 drives the plate 330 to make a circular motion. During this process, the plate 330 first lifts the multiple second ribs 270 upwards. Then, the second ribs 270 leave the arc-shaped opening but are still located within the limiting posts 260. Then, the limiting posts on the plate 330... Hook 340 collides with the second rib 270 and moves the second rib 270 along with it until the support rod 320 moves to the top of the vertical plate 351. Then, the insertion rod 352 is inserted into the second template 120. The vertical plate 351 then limits the support rod 320. The pushed second rib 270 moves the rod body 240 through the limiting post 260. The rod body 240 pulls the second rotating plate 250. A small rectangular frame is formed between the second rotating plate 250 and the first rotating plate 230, thus completing the construction of the basic frame. Cement is then poured into the basic frame until the composite plate is formed. Then, the handle 430 is turned. The handle 430 drives the extrusion component 410 to rotate through the rotating shaft 420. The extrusion component 410 separates the second template 120 from the first template 110. The structure is simple and the operation is convenient.
