Description

Technical Field

[0001] This utility model belongs to the field of template technology, specifically a quick-install orthogonal steel truss formwork system that does not require dismantling. Background Technology

[0002] The orthogonal steel truss formwork system is a prefabricated floor slab system composed of a steel truss and a non-removable concrete bottom formwork. The steel truss provides stiffness during construction and serves as the load-bearing reinforcement during the service life of the floor slab. The concrete bottom formwork does not need to be removed after pouring and directly serves as the protective layer under the floor slab, with a flat bottom that does not require plastering. This system achieves structure-formwork integration through factory prefabrication, reducing on-site steel reinforcement binding by 50%-70% and shortening the construction period by more than 30%. It also has characteristics such as fire resistance, insulation, corrosion resistance, insect resistance, and good integrity. Its application fields are wide, covering post-cast strips in basements, cast-in-place roofs, retaining walls, and other cast-in-place concrete scenarios in steel and concrete structures. It extends to various cast-in-place construction sites such as factories, schools, hospitals, residential buildings, commercial buildings, and parking lots, and is especially suitable for prefabricated building projects with high requirements for construction efficiency, cost, and environmental protection.

[0003] The disassembly and assembly of the bottom plate and side plates in the existing orthogonal steel truss formwork is very inconvenient, which increases the difficulty of disassembly and assembly between the bottom plate and side plates, thereby increasing the workload of construction workers and reducing work efficiency. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a quick-installation orthogonal steel truss formwork system that does not require disassembly. This system effectively solves the problem that the disassembly and assembly of the bottom plate and side plates in the existing orthogonal steel truss formwork is very inconvenient, which increases the difficulty of disassembly and assembly between the bottom plate and side plates, thereby increasing the workload of construction workers and reducing work efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick-installation orthogonal steel truss formwork system, comprising a bottom formwork, a side plate on one side of the bottom formwork, a steel truss on the upper part of the bottom formwork, slots at both ends of one side of the bottom formwork, slots at the top of the inner part of the two slots, discharge ports on both sides of the top of the bottom formwork, handwheels at both ends of one side of the side plate, inserts into the two slots, openings at one end of the inserts, the side plate being movably fitted onto the surface of the two inserts, and a locking block at the upper part of the inner part of the two inserts. A transmission assembly is provided on one side of the two handwheels, and the transmission assembly is connected to the two locking blocks. When the two handwheels rotate, power is output to the two locking blocks through the transmission assembly, causing the two locking blocks to engage with the two slots for limiting.

[0006] Preferably, the transmission assembly includes a retaining ring fixedly installed on one side of the two handwheels, and studs are fixedly installed inside the two retaining rings. The two studs are threadedly connected to the inside of the two insertion tubes, and one end of each stud is tightly attached to a movable seat. A fixed plate is fixedly installed in the middle of the inside of each of the two insertion tubes. An insertion hole is opened in the middle of the fixed plate. Two limiting grooves are opened inside the two insertion holes respectively. Insert rods are inserted into the inside of the two insertion holes. One end of each insertion rod is fixedly connected to the two movable seats. Two limiting strips are fixedly installed on the surface of each insertion rod respectively. The four limiting strips are slidably installed inside the four limiting grooves. A first spring is sleeved between the surfaces of the two limiting strips on the same insertion rod. The two ends of the first spring are fixedly connected to the movable seat and the fixed plate respectively. A pushing block is fixedly installed on the other end of each insertion rod. Slider blocks are fixedly installed on the upper and lower sides of the two pushing blocks. Two sliding grooves are symmetrically opened on the inner walls of the two insertion tubes respectively. The four sliders are slidably installed inside the four sliding grooves.

[0007] Preferably, the inclined surfaces at the upper part of one end of the two pushing blocks are respectively abutted against the bottom of the two clamping blocks, and both sides of the two clamping blocks are fixedly installed with sliding sleeves through connectors. Sliding rods are inserted into the interior of the four sliding sleeves, and the top of the sliding rods is fixedly connected to the inner top of the insertion tube. A second spring is sleeved on the surface of each sliding rod, and both ends of the second spring are fixedly connected to the sliding rod and the sliding sleeve respectively.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: During installation, the operator inserts two tubes into the two slots, then puts the side plate on the surface of the two tubes, and then screws the stud into the two tubes by rotating the two handwheels in sequence. When the stud rotates and moves, it pushes the rod to move in the insertion hole through the moving seat, and at the same time drives the limiting strip to move along the inside of the limiting groove, ensuring the stability of the rod movement. When the moving seat moves, it also squeezes the first spring to retract. When the rod moves, it pushes the pushing block to move. When the pushing block moves, it drives the slider to slide inside the slide groove, which increases the stability of the pushing block movement. When the pushing block moves, the pushing block moves upward.

[0009] When the locking block moves upward, two connecting heads drive two sliding sleeves to slide on the surfaces of two sliding rods, simultaneously compressing two second springs. This ensures the stability of the locking block's upward movement while also providing it with elastic reset capability. As the locking block moves upward, it engages with the slot for fixation. Simultaneously, the handwheel drives the clamping ring to press against the side plate, locking it through the threads between the stud and the insertion tube. This allows for quick and convenient installation of the bottom formwork and side plate. After installation, concrete is poured. The concrete flows into the slot and insertion tube through the discharge port and opening, sealing them tightly to ensure the overall quality of the bottom formwork. When disassembling the side plate, the operator uses the handwheel to unscrew the stud from the insertion tube, releasing the clamping ring's restraint on the side plate, allowing for quick removal. This makes the assembly and disassembly of the bottom plate and side plates in this orthogonal steel truss formwork very convenient, reducing the difficulty of assembly and disassembly, decreasing the workload of construction workers, and improving work efficiency.

[0019] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] Depend on Figures 1 to 6 The present invention includes a bottom mold 1, which is made of fine aggregate concrete of the same grade as the cast-in-place concrete and reinforced with alkali-resistant fiberglass mesh. A side plate 2 is provided on one side of the bottom mold 1 to prevent concrete loss. A steel truss 3 is integrally formed on the upper part of the bottom mold 1. Slots 6 are provided at both ends of one side of the bottom mold 1, and grooves 7 are provided at the top of each slot 6. Discharge ports 4 are provided on both sides of the top of the bottom mold 1. Handwheels 5 for rotational adjustment are provided at both ends of one side of the side plate 2. Inserted tubes 8 are inserted into the interior of each slot 6. Both the slots 6 and the inserted tubes 8 are hexagonal to prevent the inserted tubes 8 from rotating inside the slots 6. One end of each inserted tube 8... An opening 9 is provided, allowing concrete to enter the slot 6 and the insertion tube 8 through the discharge port 4 and the opening 9 during concrete pouring, sealing them tightly. The side plate 2 is movably fitted onto the surface of the two insertion tubes 8, allowing the side plate 2 to be removed from the surface of the two insertion tubes 8. The upper part of the interior of each of the two insertion tubes 8 is provided with a locking block 20, which is adapted to the two locking slots 7. The locking block 20 is locked into the interior of the locking slot 7 to form a limit. A transmission component is provided on one side of each of the two handwheels 5, which is connected to the two locking blocks 20. When the two handwheels 5 rotate, the power is output to the two locking blocks 20 through the transmission component, causing the two locking blocks 20 to be locked into the interior of the two locking slots 7 for limit.

[0021] During installation, the operator inserts two tubes 8 into the two slots 6, and then places the side plate 2 on the surface of the two tubes 8. Next, by rotating the two handwheels 5 in sequence, the transmission component is driven to move. When the transmission component moves, the locking block 20 moves up and locks into the slot 7 for fixation, thus quickly and conveniently realizing the installation between the bottom mold 1 and the side plate 2. After installation, concrete is poured in place. The concrete flows into the slots 6 and tubes 8 through the discharge port 4 and the opening 9, sealing the inside of the slots 6 and tubes 8 tightly to ensure the overall quality of the bottom mold 1.

[0022] When disassembling side plate 2, the operator can use handwheel 5 to unscrew stud 10 from the insertion tube 8, and then quickly remove side plate 2 to complete the disassembly. This makes the disassembly and assembly of the bottom plate and side plate 2 in the orthogonal steel truss formwork very convenient, reduces the difficulty of disassembly and assembly between the bottom plate and side plate 2, reduces the workload of construction workers, and improves work efficiency.

[0023] The transmission assembly includes a retaining ring 11 fixedly installed on one side of the two handwheels 5, and a stud 10 fixedly installed inside each of the two retaining rings 11. The two studs 10 are threadedly connected to the inside of the two insertion tubes 8, allowing the two studs 10 to rotate and move inside the two insertion tubes 8. One end of each stud 10 is tightly attached to a movable seat 26. A fixing plate 14 is fixedly installed in the middle of the inside of each of the two insertion tubes 8. The fixing plate 14 can prevent the cast-in-place concrete from flowing to one side of the stud 10. An insertion hole 17 is opened in the middle of each fixing plate 14. Two limiting grooves 18 are opened inside each of the two insertion holes 17. Insertion rods 13 are inserted into each of the two insertion holes 17. 3 can move within two insertion holes 17. One end of each of the two insertion rods 13 is fixedly connected to two movable seats 26. Two limiting strips 15 are fixedly installed on the surface of each of the two insertion rods 13. The four limiting strips 15 are slidably installed inside the four limiting grooves 18, so that the limiting strips 15 can move inside the limiting grooves 18. A first spring 16 is sleeved between the surfaces of the two limiting strips 15 on the same insertion rod 13. Both ends of the first spring 16 are fixedly connected to the movable seat 26 and the fixed plate 14, respectively. The first spring 16 can prevent the insertion rod 13 from moving by its own elasticity, ensuring its initial position. A push block 19 is fixedly installed on the other end of each insertion rod 13.

[0024] Rotate the two handwheels 5 in sequence to screw the stud 10 into the two insertion tubes 8. When the stud 10 rotates and moves, it will push the insertion rod 13 to move in the insertion hole 17 through the moving seat 26, and at the same time drive the limiting strip 15 to move along the inside of the limiting groove 18 to ensure the stability of the movement of the insertion rod 13. While the moving seat 26 moves, it will also squeeze the first spring 16 to retract. When the insertion rod 13 moves, it will push the pushing block 19 to move.

[0025] Slider 25 is fixedly installed on the upper and lower sides of the two push blocks 19. Two grooves 12 are symmetrically opened on the inner walls of the two insertion tubes 8. The four sliders 25 are slidably installed inside the four grooves 12 and can move inside the four grooves 12.

[0026] When the push block 19 moves, it causes the slider 25 to slide inside the groove 12, which increases the stability of the push block 19 when it moves.

[0027] The upper slope of one end of each of the two pushing blocks 19 is closely attached to the bottom of the two locking blocks 20. Both sides of the two locking blocks 20 are fixedly installed with sliding sleeves 22 through connectors 21. Each of the four sliding sleeves 22 has a sliding rod 23 inserted inside. The four sliding sleeves 22 can slide along the surface of the four sliding rods 23. The top of each sliding rod 23 is fixedly connected to the inner top of the insertion tube 8. Each sliding rod 23 has a second spring 24 sleeved on its surface. Both ends of the second spring 24 are fixedly connected to the sliding rod 23 and the sliding sleeve 22 respectively. The second spring 24 enables the two locking blocks 20 to have the ability to elastically reset through its own elastic force.

[0028] When the pushing block 19 moves, it pushes the locking block 20 upward. When the locking block 20 moves upward, it drives the two sliding sleeves 22 to slide on the surface of the two sliding rods 23 through the two connectors 21, and simultaneously squeezes the two second springs 24. This ensures the stability of the locking block 20 while giving it the ability to elastically reset. When the locking block 20 moves upward, it will be locked into the inside of the slot 7 for fixation. At the same time as the locking block 20 is locked into the slot 7, the handwheel 5 will drive the clamping ring 11 to press against the side plate 2. It is locked by the thread between the stud 10 and the insertion tube 8, thus quickly and conveniently realizing the installation between the bottom mold 1 and the side plate 2.
