Description

Technical Field

[0001] This invention relates to the field of building formwork technology, and in particular to a shear wall steel formwork assembly and its construction method. Background Technology

[0002] Formwork is a temporary support structure, manufactured according to design requirements, to shape concrete structures and components according to specified positions and geometric dimensions, maintain their correct position, and bear the self-weight of the formwork and external loads acting on it. Shear walls, also known as wind-resistant walls, earthquake-resistant walls, or structural walls, are walls in buildings or structures that primarily bear horizontal and vertical loads (gravity) caused by wind loads or earthquakes, preventing structural shear failure. Steel formwork is required to shape the concrete when casting shear walls.

[0003] A search revealed that invention patent CN103806643B discloses a shear wall steel formwork assembly and its construction method, comprising several corner steel formworks, several wall surface steel formworks, several connectors, and several fixing components for connecting adjacent wall surface steel formworks and corner steel formworks; the bottom of the wall surface steel formwork is provided with a lower groove, and a connecting plate is fixed at the upper edge of the lower groove; one end of the connector can pass through the lower groove and abut against the lower end face of the connecting plate, and the lower groove and the connector are tightly fitted and fixed; the upper end face of the wall surface steel formwork is provided with an upper groove, and the upper groove can be tightly fitted and fixed with the connector; the corner steel formworks and wall surface steel formworks are provided with fixing plates with fixing holes around their perimeters.

[0004] It has certain drawbacks:

A guide post located on one side is rotatably connected to multiple rotating shafts on one side of one of the longitudinal reinforcing plates, corresponding to multiple combined insertion holes. A sliding sleeve rod is slidably sleeved on the outer side of the guide post. A spring sleeved on the outer side of the sliding sleeve rod is connected to the lower end of the sliding sleeve rod. The lower end of the spring is connected to the inner side of the outer frame. A rotating rod is fixed at one end of each of the multiple rotating shafts on one side.

A locking groove is provided at one end of each of the multiple combined insertion rods on the outer side.

[0009] Preferably, the locking groove includes two straight sliding grooves symmetrically opened at one end on both sides of the combined plug rod and two arc-shaped sliding grooves opened on both sides of the combined plug rod. One end of the two arc-shaped sliding grooves is connected to one end of the two straight sliding grooves respectively. The locking claw is adapted to the inner side of the straight sliding groove and the arc-shaped sliding groove.

[0010] Preferably, the folding and storage mechanism includes two first rotating shafts rotatably connected to the upper and lower ends of one of the outer frames and two slide rails fixed to the upper and lower ends of an adjacent outer frame. Guide rods are fixed to the inner sides of the two slide rails, and sliders are slidably connected to the inner sides of the two slide rails. The two sliders are slidably sleeved on the outer sides of the two guide rods, and second rotating shafts are rotatably connected to the upper sides of the two sliders.

[0034] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] This invention provides an improved shear wall steel formwork assembly and its construction method. The technical solution of this invention is as follows:

[0036] Example 1:

[0037] like Figures 1 to 8As shown, this embodiment of the invention provides a shear wall steel formwork assembly, comprising multiple structurally identical component units. Each component unit includes a steel formwork 1, with an outer frame 2 fixed to one side of the steel formwork 1. Two parallel longitudinal reinforcing plates 3 are fixed to the inner side of the outer frame 2, and multiple transverse reinforcing plates 4 are fixed at equal intervals between the two longitudinal reinforcing plates 3. The assembly also includes: a component assembly mechanism located on both sides of the outer frame 2; and a folding and storage mechanism located between two adjacent component units. The component assembly mechanism includes multiple combination rods 6 equally spaced on one side of the outer frame 2, multiple combination holes 5 opened on the other side of the outer frame 2 corresponding to the positions of the multiple combination rods 6, and a component fixed to one side of the inner side of the outer frame 2. The guide post 8 is rotatably connected to one side of one of the longitudinal reinforcing plates 3, corresponding to the positions of multiple combination insertion holes 5. A sliding sleeve rod 9 is slidably sleeved on the outside of the guide post 8. A spring 10 sleeved on the outside of the guide post 8 is connected to the lower end of the sliding sleeve rod 9. The lower end of the spring 10 is connected to the inner side of the outer frame 2. A rotating rod 14 is fixed at one end of each of the multiple rotating shafts 12. A sliding groove 15 is opened inside each of the multiple rotating rods 14. Two locking claws 13 are symmetrically fixed on both sides of each of the multiple rotating shafts 12. A sliding pin 11 is fixed on one side of the sliding sleeve rod 9 corresponding to the position of the rotating rod 14. The multiple sliding pins 11 are slidably connected to the inner side of the multiple sliding grooves 15 respectively. A locking groove is provided at one end of each of the multiple combination insertion rods 6.

[0038] Furthermore, the locking groove includes two straight sliding grooves 16 symmetrically opened on both sides of the combined insert rod 6 at one end and two arc-shaped sliding grooves 17 opened on both sides of the combined insert rod 6. One end of the two arc-shaped sliding grooves 17 is connected to one end of the two straight sliding grooves 16 respectively. The locking claw 13 is adapted to the inner side of the straight sliding grooves 16 and the arc-shaped sliding grooves 17. The locking groove cooperates with the locking claw 13 to fix the combined insert rod 6 and one end of the rotating shaft 12, thereby fixing the two adjacent outer frames 2.

[0039] Furthermore, the folding and storage mechanism includes two first rotating shafts 19 rotatably connected to the upper and lower ends of one of the outer frames 2 and two slide rails 21 fixed to the upper and lower ends of an adjacent outer frame 2. Guide rods 22 are fixed to the inner side of each of the two slide rails 21, and sliders 23 are slidably connected to the inner side of each of the two slide rails 21. The two sliders 23 are respectively slidably sleeved on the outer side of the two guide rods 22, and second rotating shafts 24 are rotatably connected to the upper side of each of the two sliders 23. Storage connecting rods 20 are fixed to one side of the upper end of each of the two first rotating shafts 19, and one end of each storage connecting rod 20 is rotatably connected to the two second rotating shafts 24. Through the folding and storage mechanism, adjacent outer frames 2 and steel templates 1 can be stored and stacked. During transportation, there is no need to disassemble the components into multiple scattered parts, which not only reduces the space occupied and facilitates movement and transportation, but also prevents the loss of parts.

[0040] Furthermore, each of the steel formwork 1 has an L-shaped base frame 25 fixed at its lower end. The inner ends of the L-shaped base frame 25 are fixed with two reinforcing plates 27, and the bottom of the L-shaped base frame 25 is provided with multiple mounting screw holes 26. The L-shaped base frame 25 is used to support the steel formwork 1.

[0041] Furthermore, a lever 28 is fixed at the middle position on one side of the sliding sleeve 9. The lever 28 is used to drive the sliding sleeve 9 to move up and down, which facilitates operation.

[0042] Furthermore, two port chamfers 18 are symmetrically provided on both sides of one end of the two straight slide grooves 16. The port chamfers 18 serve as guides, making it easier for the locking claws 13 to be inserted into the inside of the straight slide grooves 16.

[0043] Furthermore, both arc-shaped grooves 17 are quarter-circle arc structures, allowing the locking claw 13 to rotate 90° to fix the combined insert rod 6, facilitating operation.

[0044] Furthermore, each of the other ends of the multiple combined insert rods 6 is fixed with an insert rod fixing plate 7. One side of each of the multiple insert rod fixing plates 7 is fixed to the inner side of the outer frame 2. The insert rod fixing plate 7 can distribute the pressure to the inner side of the outer frame 2 to prevent the outer frame 2 from being stretched and deformed.

[0045] Furthermore, the first pivot 19 is a damping pivot, which can prevent the storage link 20 from rotating, thereby preventing the outer frame 2 from becoming loose after storage.

[0046] Example 2:

[0047] This embodiment provides a construction method for steel formwork components for shear walls, specifically including the following steps:

[0048] Step 1: Use fixing bolts to pass through the mounting screw holes 26 to fix the L-shaped base frame 25 to the ground, thereby vertically fixing the steel template 1 and the outer frame 2 to the ground;

[0049] Step 2: Based on the length of the shear wall, unfold a specified number of outer frames 2 using a folding and storage mechanism, so that multiple outer frames 2 are arranged side by side, thereby arranging multiple steel formwork 1s side by side. The multiple steel formwork 1s arranged side by side are combined to form a large-area formwork to shape the concrete.

[0050] Working principle: During transportation, multiple individual components can be folded using the folding and storage mechanism. First, one of the outer frames 2 is pulled laterally. The outer frame 2 moves the two slide rails 21 at both ends, creating relative movement between the slider 23 and the slide rails 21. When the slider 23 moves to the other end of the slide rail 21, the combination insertion rod 6 is pulled out from the inside of the combination insertion hole 5. Then, the storage connecting rod 20 is rotated. One end of the storage connecting rod 20, through the slider 23 and the slide rails 21, drives this outer frame 2 to rotate towards the front of the adjacent outer frame 2, thus allowing the two adjacent outer frames 2 to rotate. Stacking and folding reduces the overall volume of components during transport, facilitating movement and transportation. In use, based on the above principle, the storage linkage 20 is rotated in the reverse direction. The storage linkage 20, via the slider 23 and slide rail 21, rotates the stacked outer frame 2 to the side. This outer frame 2 is then pushed towards an adjacent outer frame 2, causing the combination insertion rod 6 on one side of this outer frame 2 to insert into the inner side of the combination insertion hole 5 on the side of the adjacent outer frame 2. Then, the lever 28 of the single-unit combination mechanism is moved downwards, causing the sliding sleeve 9 to move downwards. 9 drives multiple sliding pins 11 on one side to move downwards. These sliding pins 11 are slidably connected to multiple sliding grooves 15. Therefore, when the sliding pins 11 move downwards, they can drive the rotating rod 14 to rotate downwards around the rotating shaft 12 through the sliding connection. The rotating rod 14 drives the rotating shaft 12 to rotate, and the rotating shaft 12 drives the two locking claws 13 on its outer side to rotate. The rotating shaft 12 rotates 90°, at which point the two locking claws 13 and the two straight sliding grooves 16 are aligned. Then, the combined insertion rod 6 is inserted again into the combined insertion hole 5. At this time, the two locking claws 13 can be inserted into the two... The inner end of the straight slide groove 16 is then opened, and the sliding sleeve rod 9 is released. Under the force of the spring 10, the sliding sleeve rod 9 moves upward and resets. Through the above principle, the rotating shaft 12 can be rotated 90° in the opposite direction to reset. The rotating shaft 12 drives the two locking claws 13 to rotate in the opposite direction. The two locking claws 13 can be screwed into the inner side of the two arc-shaped slide grooves 17 respectively, thereby locking the combined insert rod 6 with the rotating shaft 12, and then fixing the two adjacent outer frames 2. This greatly reduces the difficulty of installing and assembling the template, eliminates the need to install multiple fixing bolts, and improves construction efficiency.

[0051] The foregoing description enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
