Description

Technical Field

[0001] This invention belongs to the field of building engineering technology, specifically relating to a large-span, two-way dense rib assembled integral floor slab formwork structure and its construction method. Background Technology

[0002] Ribbed floor slabs refer to unidirectional or bidirectional ribbed floor slabs with a rib spacing of less than or equal to 1.5 meters. Among them, bidirectional ribbed floor slabs have better load-bearing performance because they bear the load from both directions. They have a small self-weight, save steel consumption, and are technically and economically reasonable, making them suitable for large-space, multi-story buildings.

[0003] Traditional ribbed floor slab structures often use positioning steel bars, steel pipes, or structural steel for fixing and reinforcement when installing the formwork. This requires high construction precision and operational skills, making construction difficult and prone to inaccurate positioning and unstable fixing. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a large-span, two-way densely ribbed assembled integral floor slab formwork structure and construction method to solve the problems mentioned in the background art or achieve better technical effects.

[0005] To solve the above-mentioned technical problems, the inventors derived the technical solution of this invention through practice and summarization. This invention discloses a large-span, bidirectional, densely ribbed, assembled integral floor slab formwork structure, including a base plate and a formwork body. The interior of the formwork body has two mounting grooves, and the front sides of the inner surfaces of the two mounting grooves are slidably connected to snap-fit ​​components for fixing the formwork body. One side of the inner surfaces of the two mounting grooves is slidably connected to a control component for controlling the movement of the snap-fit ​​components. The rear side of the interior of the formwork body has a sliding groove, and the inner surface of the sliding groove is slidably connected to a linkage component.

[0006] When installing the mold shell body on the base plate surface, simply slide the mold shell body from top to bottom into the positioning groove, and drive the locking block in the locking component to slide into the locking groove to complete the fixing of the mold shell body. The operation is simple, ensures the accuracy of positioning, and improves the stability of the mold shell body.

[0007] In a preferred embodiment of the present invention, a positioning groove is provided on the upper surface of the base plate, and the mold shell body is slidably disposed inside the positioning groove.

[0008] In a preferred embodiment of the present invention, the snap-fit ​​component includes a snap-fit ​​block. A sliding groove is provided inside the mold body on the front side of the mounting groove. A spring is fixedly connected to one end of the inner surface of the sliding groove, and a slider is fixedly connected to one end of the spring. The slider slides inside the sliding groove and is fixedly connected to the snap-fit ​​block. Snap-fit ​​slots are provided on both sides of the inner surface of the base plate, and the snap-fit ​​block slides inside the mounting groove and the snap-fit ​​slots, respectively.

[0009] In a preferred embodiment of the present invention, one side of the lower surface of the card block is curved.

[0010] In a preferred embodiment of the present invention, the control component includes a sliding plate and a rotating plate. The sliding plate is slidably disposed inside the mounting groove. One end of the outer surface of the sliding plate is fixedly connected to a mounting block, and the rear side of the mounting block is fixedly connected to a mounting block. One end of the rotating plate is rotatably connected to the mounting block via a rotating shaft, and the other end of the rotating plate is rotatably connected to the mounting block via a rotating shaft.

[0011] In a preferred embodiment of the present invention, the linkage includes a connecting plate 1, which is slidably disposed inside the slide groove 2. One end of the sliding plate 1 extends into the slide groove 2 and is fixedly connected to the connecting plate 1. An inclined surface is formed on the upper surface of the connecting plate 1. An installation groove 2 is formed inside the mold body above the connecting plate 1. Two springs 2 are fixedly connected to the inner top surface of the installation groove 2. A sliding plate 2 is fixedly connected between the lower ends of the two springs 2. The sliding plate 2 is slidably disposed inside the installation groove 2.

[0012] In a preferred embodiment of the present invention, the inner surface of the mold shell body is provided with a movable groove, and a connecting plate is fixedly connected to one side of the outer surface of the sliding plate, the connecting plate being slidably disposed inside the movable groove.

[0013] In a preferred embodiment of the present invention, a groove is provided on the lower surface of the base plate.

[0014] This invention also discloses a construction method for a large-span, two-way closely ribbed precast monolithic floor slab formwork structure, the specific operation of which is as follows:

[0015] When the mold body needs to be installed, slide the mold body from top to bottom into the positioning groove, so that the curved surface of the locking block contacts the upper surface of the base plate. Continue to move the mold body downward, so that the locking blocks and sliders on both sides slide into the installation groove one and compress the spring one. At the same time, under the action of the rotating plate, the sliding plate one and the connecting plate one move backward. When the mold body slides to the bottom surface of the positioning groove, the slider drives the locking block to slide into the groove under the elastic force of the spring one, thereby fixing the position of the mold body. Then, lay the steel mesh on the top plate and pour the top plate concrete.

[0016] After the concrete has hardened, when it is necessary to disassemble the formwork body, the construction worker pulls down the connecting plate two through the slot, causing the sliding plate two to slide down inside the installation slot two and stretching the spring two, so that the sliding plate two contacts the inclined surface opened on the surface of the connecting plate one, causing the connecting plate one to slide backward inside the sliding slot two, thereby causing the sliding plate one to slide backward synchronously. The sliding of the sliding plate one causes the rotating plate to rotate, while simultaneously causing the locking block and slider to slide into the installation slot one and compress the spring one, causing the locking block to disengage from the slot. Then, the worker slides the bottom plate down, separating the bottom plate from the formwork body and the concrete. Then, the slider, locking block and sliding plate two are reset under the elastic force of the spring one and spring two respectively, making it convenient for the next installation and use. Finally, the formwork body is pulled down to detach the formwork body from the concrete surface.

[0017] Compared with the prior art, the present invention can achieve the following technical effects:

[0018] When installing the mold shell body on the base plate surface, the present invention only requires sliding the mold shell body from top to bottom into the positioning groove, thereby driving the locking block in the locking member to slide into the locking groove to complete the fixing of the mold shell body. The operation is simple, ensures the accuracy of positioning, improves the stability of the mold shell body, and is convenient for installation and disassembly. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0031] The application principle of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] refer to Figure 1-8 A large-span, bidirectional, densely ribbed, assembled integral floor slab formwork structure includes a base plate 1 and a formwork body 11. The interior of the formwork body 11 has two mounting grooves 3. The front sides of the inner surfaces of the two mounting grooves 3 are slidably connected to snap-fit ​​components for fixing the formwork body 11. One side of the inner surfaces of the two mounting grooves 3 is slidably connected to control components for controlling the movement of snap-fit ​​components. The rear side of the interior of the formwork body 11 has a sliding groove 5. The inner surface of the sliding groove 5 is slidably connected to a linkage component.

[0033] When installing the mold body 11 on the surface of the base plate 1, simply slide the mold body 11 from top to bottom into the positioning groove 2, and drive the locking block 34 in the locking member to slide into the locking groove 35 to complete the fixing of the mold body 11. The operation is simple, ensures the accuracy of positioning, and improves the stability of the mold body 11. Specific Implementation Example 1

[0035] A positioning groove 2 is formed on the upper surface of the base plate 1, and the mold shell body 11 is slidably disposed inside the positioning groove 2. The snap-fit ​​component includes a snap-fit ​​block 34. A sliding groove 31 is formed inside the mold shell body 11 on the front side of the mounting groove 3. A spring 32 is fixedly connected to one end of the inner surface of the sliding groove 31, and a slider 33 is fixedly connected to one end of the spring 32. The slider 33 is slidably disposed inside the sliding groove 31 and is fixedly connected to the snap-fit ​​block 34. Slots 35 are formed on both sides of the inner surface of the base plate 1, and the snap-fit ​​block 34 is slidably disposed inside the mounting groove 3 and the slots 35 respectively. One side of the lower surface of the snap-fit ​​block 34 is curved.

[0036] Implementation Process: When the mold body 11 needs to be installed, slide the mold body 11 from top to bottom into the positioning groove 2, so that the curved surface of the locking block 34 contacts the upper surface of the base plate 1. Continue to move the mold body 11 downward, so that the locking blocks 34 and sliders 33 on both sides slide into the mounting groove 3 and compress the spring 32. At the same time, under the action of the rotating plate 43, the sliding plate 4 and the connecting plate 51 move backward. When the mold body 11 slides to the bottom surface of the positioning groove 2, the slider 33, under the elastic force of the spring 32, drives the locking block 34 to slide into the groove 35, thereby fixing the position of the mold body 11. Then, lay the steel mesh on top of the base plate 1, and then pour the top slab concrete. Implementation Benefits: The mold body 11 is fixed. Specific Implementation Example 2

[0038] The control components include a sliding plate 4 and a rotating plate 43. The sliding plate 4 slides inside the mounting groove 3. One end of the outer surface of the sliding plate 4 is fixedly connected to a mounting block 41. The rear side of the locking block 34 is fixedly connected to a mounting block 42. One end of the rotating plate 43 is rotatably connected to the mounting block 41 via a rotating shaft, and the other end of the rotating plate 43 is rotatably connected to the mounting block 42 via a rotating shaft. The linkage components include a connecting plate 51, which slides inside the sliding groove 5. One end of the sliding plate 4 extends into the sliding groove 5 and is fixedly connected to the connecting plate 51. The upper surface of the connecting plate 51 has an inclined surface 52. The mold body 11 has a mounting groove 53 located above the connecting plate 51. Two springs 54 are fixedly connected to the inner top surface of the mounting groove 53. A sliding plate 55 is fixedly connected between the lower ends of the two springs 54 and slides inside the mounting groove 53. The inner surface of the mold shell body 11 is provided with a movable groove 6, and a connecting plate 61 is fixedly connected to one side of the outer surface of the sliding plate 55. The connecting plate 61 is slidably disposed inside the movable groove 6. The lower surface of the base plate 1 is provided with a slot 62.

[0039] Implementation process: After the concrete has solidified, when the formwork body 11 needs to be disassembled, the construction workers pull down the connecting plate 61 through the slot 62, causing the sliding plate 55 to slide down inside the installation slot 53 and stretch the spring 54, so that the sliding plate 55 contacts the inclined surface 52 on the surface of the connecting plate 51, causing the connecting plate 51 to slide backward inside the sliding slot 5, thereby causing the sliding plate 4 to slide backward synchronously. The sliding of the sliding plate 4 causes the rotating plate 43 to rotate, while the locking block 34 and the slider 33 slide into the installation slot 3 and compress the spring 32, causing the locking block 34 to disengage from the slot 35. Then, the workers slide the bottom plate 1 down, separating the bottom plate 1 from the formwork body 11 and the concrete. Then, the slider 33, the locking block 34 and the sliding plate 55 are reset under the elastic force of the spring 32 and the spring 54, respectively, for easy installation and use next time. Then, the formwork body 11 is pulled down to detach the formwork body 11 from the concrete surface. Benefits of implementation: It facilitates the removal of the base plate 1 and the formwork body 11 from under the concrete.
