Description

Technical Field

[0001] This invention relates to the field of exterior wall construction technology, specifically to a single-sided formwork stabilization device for basement exterior walls. Background Technology

[0002] During the construction of basement exterior walls, it is usually necessary to support and reinforce the formwork on one side to ensure the quality of wall formation, the accuracy of structural dimensions, and the safety of the entire construction process. In current projects, inclined support members are often used to support and reinforce the formwork on one side. The support members are spaced along the height of the wall, and their ends directly press against the back ribs and panels of the formwork on the side that is close to the wall. Through the coordinated force of multiple members, they jointly resist the lateral pressure generated during concrete pouring, limit the deformation, displacement, and overturning of the formwork, thereby ensuring the overall stability and support reliability of the formwork system.

[0003] For example, patent document CN217812381U discloses a single-sided support and reinforcement device for basements. Support rods are installed on diagonal braces via multiple reinforcing struts. When supporting and reinforcing the basement exterior wall formwork, the support rods can be tightly attached to the formwork, and the bottom ends of the diagonal braces are fixed to the ground. At this point, the support rods, diagonal braces, and reinforcing struts form a triangular support and reinforcement structure, providing stable support for the exterior wall formwork. Furthermore, because the support rods are tightly attached to the formwork, the contact area between them is increased, reducing the number of support and reinforcement devices required, improving support and reinforcement efficiency and exterior wall construction efficiency. It also disperses the stress on the formwork, preventing it from being crushed and damaged. The struts, diagonal struts, and reinforcing supports are slidably connected by hinges and grooves, allowing the support and reinforcing device to be folded into a long strip when not in use, thus facilitating storage and transport. Although the above application has many beneficial effects, it still has the following shortcomings: In actual use, due to the construction stage of the exterior wall, a large amount of flying stones, cement mortar, and wet concrete debris are easily generated on site. These debris can easily penetrate and adhere to the hinge parts and the interior of the groove structure of the device, causing problems such as poor hinge rotation and groove jamming, which seriously affect the normal operation and stability of the device, and also bring many inconveniences to the deployment, adjustment, and storage of the device. Summary of the Invention

[0004] To address the problems in the prior art, the present invention provides a single-sided formwork stabilization device for basement exterior walls.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a single-sided formwork stabilization device for basement exterior walls, including an installation rod, a template is fixedly connected to one side of the installation rod, a sliding groove is provided on the installation rod, and a support mechanism is provided on both the installation rod and the sliding groove; The mounting rod, template, and slide are all equipped with a blocking mechanism, which includes two mounting slots, two guide slots, two rotating rods, two round rods, a lifting seat, and two first strong magnets. Each mounting slot has a slidably connected pressure seat. Each pressure seat has a guide block fixedly connected to the top of the guide slot. Each rotating rod has a connecting plate fixedly connected to the top of the rotating rod. Each connecting plate has a blocking frame fixedly connected to one side of the connecting plate. Each rotating rod has a third strong magnet fixedly connected to the bottom of the connecting plate. Each round rod has a rotating seat rotatably connected to the rotating seat. Each rotating seat has a symmetrically arranged second strong magnet fixedly connected to it. Each blocking frame has multiple passage slots.

[0006] Specifically, the support mechanism includes a hinge seat, a moving block, and a lead screw. A support rod is hinged to the hinge seat. Two hinge seats are fixedly connected to one side of the moving block. A crossbar is hinged to the two hinge seats. Three hinge seats are fixedly connected to the support rod at a position corresponding to one end of the crossbar. A stabilizing seat is hinged to one end of the support rod.

[0007] Specifically, the hinge seat is fixedly connected to the top of the corresponding slide groove on the other side of the mounting rod, the moving block is slidably connected to the inside of the slide groove near the bottom, the three hinge seats are hinged to the crossbar, the lead screw is rotatably connected in the slide groove, and the lead screw is threadedly connected to the moving block.

[0008] Specifically, the mounting slots are symmetrically opened at the middle position of the mounting rod, the guide slots are all opened at the top position of the corresponding mounting slots on the mounting rod, and the guide blocks are all slidably connected inside the corresponding guide slots.

[0009] Specifically, the rotating rods are all rotatably connected to the mounting rod at positions adjacent to the mounting groove. The round rods are symmetrically rotatably connected to the template. The lifting seat is slidably connected to the middle position inside the slide groove. The lifting seat is threadedly connected to the lead screw. The lifting seat is located at the middle position of two corresponding pressure seats inside the slide groove. One corner of each pressure seat is inclined. One end of each pressure seat is arc-shaped. The arc-shaped positions of the pressure seats abut against the corresponding second strong magnets. The first strong magnets are all fixedly connected to the mounting rod at the other side adjacent to the mounting groove. One end of each first strong magnet is inclined.

[0010] Specifically, the rotating base is made of permalloy at the middle position corresponding to the second strong magnet, both ends of the rotating base are arc-shaped, and one end of the rotating base abuts against the corresponding third strong magnet.

[0011] The beneficial effects of this invention are: By setting up a linkage blocking mechanism, when the support mechanism is deployed, the two blocking frames automatically merge and close the key structures such as the hinges and slides on the installation rod, effectively preventing the intrusion and adhesion of impurities such as stones, cement mortar, and wet concrete debris splashed on the construction site. This avoids problems such as poor hinge rotation and slide jamming from the root, ensuring that the device can be smoothly adjusted and rotated throughout the process, and greatly improving the reliability of the formwork support device. The opening and closing of the blocking mechanism and the retraction of the support mechanism are fully linked through components such as screws and lifting seats, eliminating the need for additional manual operation steps. When the support mechanism is extended, the blocking frame closes to protect, and when the support mechanism is retracted, the blocking frame separates to avoid collisions. This not only eliminates the need to operate the protective structure separately, but also avoids collisions and interference between the protective structure and the support components, reducing the difficulty of operation for construction personnel and improving the efficiency of the formwork device's deployment and retraction. The linkage between the blocking mechanism and the supporting mechanism is achieved entirely through the mechanical transmission of the lead screw and the magnetic attraction of the magnet. No external electric or pneumatic power source is required. This not only meets the requirements of green construction, but also perfectly adapts to the scenario of no external power source and complex construction environment in the early stage of basement construction. It avoids problems such as wiring layout and fault maintenance caused by additional power sources, and improves the on-site applicability of the device. Attached Figure Description

[0015] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0016] Please see Figures 1 to 7 The present invention provides the following technical solutions: Example 1: A single-sided formwork stabilization device for basement exterior walls includes an installation rod 1. A template 2 is fixedly connected to one side of the installation rod 1. A groove 3 is provided on the installation rod 1. A support mechanism 4 is provided on both the installation rod 1 and the groove 3. The support mechanism 4 includes a hinge seat 41, a moving block 42, and a screw rod 48. A support rod 43 is hinged to the hinge seat 41. Two hinge seats 44 are fixedly connected to one side of the moving block 42. A crossbar 45 is hinged to the two hinge seats 44. A third hinge seat 46 is fixedly connected to one end of the support rod 43 corresponding to one end of the crossbar 45. A stabilizing seat 47 is hinged to one end of the support rod 43. A hinge seat 41 is fixedly connected to the other side of the installation rod 1 at the top of the groove 3. The moving block 42 is slidably connected inside the groove 3 near the bottom. The third hinge seat 46 is hinged to the crossbar 45. The screw rod 48 is rotatably connected in the groove 3 and threadedly connected to the moving block 42.

[0017] In use, the pry bar can be directly inserted into the circular object at the top of the screw 48, and then the screw 48 can be rotated directly. The rotation of the screw 48 will cause the moving block 42 to move down in the slide 3. The moving block 42 will cause the second hinge seat 44 to move. The downward movement of the second hinge seat 44 will act on one end of the crossbar 45, while the other end of the crossbar 45 will act on the third hinge seat 46. At this time, the force on the third hinge seat 46 will act on the support rod 43. The support rod 43 will then rotate around the first hinge seat 41 as the center. The support rod 43 will drive the stabilizing seat 47 to rotate together. When the support rod 43 rotates to the designated position, stop rotating the screw 48. Then, place the bottom of the stabilizing seat 47 on the ground, and then make the template 2 fit against the basement exterior wall to provide support. To retract, simply rotate the screw 48 in the opposite direction.

[0018] Example 2: The technical solution of this example that differs from that of Example 1 includes: the mounting rod 1, the template 2 and the slide 3 are all provided with a blocking mechanism 5. The blocking mechanism 5 includes two mounting grooves 51, two guide grooves 52, two rotating rods 53, two round rods 54, a lifting seat 55 and two first strong magnets 56. Inside each mounting slot 51, a pressure seat 57 is slidably connected. A guide block 58 is fixedly connected to the top of each pressure seat 57 at the position corresponding to the guide slot 52. A connecting plate 59 is fixedly connected to the top of each rotating rod 53. A blocking frame 60 is fixedly connected to one side of each connecting plate 59. A third strong magnet 61 is fixedly connected to each rotating rod 53 at the bottom position corresponding to the connecting plate 59. A rotating seat 62 is rotatably connected to each round rod 54. A second strong magnet 63 is fixedly connected to each rotating seat 62. Multiple passage slots 64 are opened on each blocking frame 60.

[0019] The mounting slots 51 are symmetrically formed at the middle position of the mounting rod 1. The guide slots 52 are all formed at the top positions of the mounting slots 51 on the mounting rod 1. The guide blocks 58 are all slidably connected inside the corresponding guide slots 52. The rotating rods 53 are all rotatably connected to the mounting rod 1 at positions adjacent to the mounting slots 51. The round rods 54 are symmetrically rotatably connected to the template 2. The lifting seat 55 is slidably connected at the middle position inside the slide groove 3. The lifting seat 55 is threadedly connected to the lead screw 48. The lifting seat 55 is located inside the slide groove 3 at the middle position of the two pressure seats 57. One corner of the pressure seat 57 is inclined, and one end of the pressure seat 57 is arc-shaped. The arc-shaped position of the pressure seat 57 abuts against the corresponding second strong magnet 63. The first strong magnet 56 is fixedly connected to the mounting rod 1 on the other side adjacent to the mounting groove 51. One end of the first strong magnet 56 is inclined. The middle position of the rotating seat 62 corresponding to the second strong magnet 63 is made of permalloy. Both ends of the rotating seat 62 are arc-shaped, and one end of the rotating seat 62 abuts against the corresponding third strong magnet 61.

[0020] When in use, when the support mechanism 4 is in the unfolded state, the two blocking frames 60 in the blocking mechanism 5 are in the merged state. In this state, the blocking frames 60 enclose the components on the mounting rod 1, which can prevent various debris from the construction site from splashing into the components on the device, thereby avoiding the phenomenon of device malfunction and chute 3 jamming. This provides favorable conditions for the unfolding and storage of the device. When the device needs to be retracted, it is only necessary to separate the template 2 from one side of the outer wall, and then rotate the screw 48 in the opposite direction by prying. The rotation of the screw 48 will drive the moving block 42 and the lifting seat 55 to move upward. The upward movement of the moving block 42 will enable the components to cooperate through the two hinge seats 44, thereby enabling the support rod 43 to reset and rotate. The passage groove 64 on the blocking frame 60 can provide the initial rotation conditions for the rotation and reset of the support rod 43, and can prevent the support rod 43 from colliding with the blocking frame 60 during the reset process. As the lifting seat 55 moves upward in the slide groove 3, it slowly moves out from between the two pressure seats 57. At this time, the lifting seat 55 no longer presses against the two pressure seats 57, so the pressure seats 57 are in a state of losing support and can no longer apply pressure to the corresponding second strong magnet 63. At this time, the first strong magnet 56 will attract the second strong magnet 63 through the opposite magnetic attraction force. The second strong magnet 63 will rotate towards the first strong magnet 56 due to the magnetic attraction of the first strong magnet 56. The rotation of the second strong magnet 63 will drive the rotating seat 62. When both rotating seats 62 and the circular rod 54 rotate together, the arc-shaped positions of the rotating seats 62 will press against the arc-shaped positions of the pressure seats 57 during the rotation. At this time, the pressure seats 57 will retract into the slide groove 3. The movement of the pressure seats 57 will cause the guide blocks 58 to slide in the guide groove 52. After the pressure seats 57 and guide blocks 58 have finished moving, the second strong magnets 63 will be magnetically connected to the inclined surfaces of the corresponding first strong magnets 56. At the same time, the arc-shaped positions of the rotating seats 62 will no longer exert pressure on the third strong magnets 61. At this time, the other part of the rotating seats 62 is not connected to any object. Each of the second strong magnets 63 applies a magnetic attraction force to its corresponding third strong magnet 61. At this time, each third strong magnet 61 rotates towards its corresponding second strong magnet 63. The rotation of the third strong magnet 61 drives the rotating rod 53 to rotate, which in turn drives the connecting plate 59 and the blocking frame 60 to rotate. The two blocking frames 60 then separate, and the third strong magnet 61 magnetically connects with its corresponding second strong magnet 63. The area between the two second strong magnets 63 on the rotating base 62 is made of permalloy to prevent adjacent second strong magnets from being magnetically attracted. When the magnetic field of magnet 63 becomes disordered, each of the second strong magnets 63 can be magnetically connected to the first strong magnet 56 and the third strong magnet 61 respectively. Then, the screw 48 is continuously rotated to allow the support rod 43 to return to its normal retracted state. The opening and closing of the blocking mechanism 5 will be completed in the initial state of the support rod 43's retraction, preventing its operation from affecting the complete retraction of the support rod 43. The opening and closing of the blocking mechanism 5 is linked to the retraction and extension of the support mechanism 4. No extra actions are required during operation. When the support mechanism 4 retracts, the blocking mechanism 5 retracts synchronously, and vice versa. The operation is extremely convenient. When the device is unfolded, rotating the lead screw 48 forward causes the lifting seat 55 and the moving block 42 to move downward. When the support rod 43 is about to be fully unfolded, the lifting seat 55 moves to the top of the pressure seat 57 and then presses the inclined corners of the two pressure seats 57. The pressure seats 57 will protrude outward from the mounting rod 1. The protruding pressure seats 57 will press the corresponding second strong magnet 63 on the rotating seat 62, causing the second strong magnet 63 to separate from the first strong magnet 56. The second strong magnet 63 will cause the rotating seat 62 to rotate towards the third strong magnet 61. The rotation and pressing of the rotating seat 62 will also cause the third strong magnet 61 to rotate, thus separating it from the corresponding second strong magnet 63 that is magnetically connected. The rotation of the third strong magnet 61 will drive the connecting plate 59 and the blocking frame 60 to rotate through the rotating rod 53. At this time, the two blocking frames 60 will rotate and close, completing the operation.
