Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a mountain-shaped locking structure for preventing loosening and positioning. Background Technology

[0002] In construction engineering, especially in the formwork erection process of concrete components such as shear walls, columns, and beams, a locking structure using tie rods in combination with U-shaped clips and U-shaped nuts is widely used to clamp the back rib system on both sides of the formwork and resist the lateral pressure generated during concrete pouring. The traditional U-shaped nut locking method is simple in structure and low in cost, and has been widely used.

[0003] However, in actual construction, especially under high vibration and high lateral pressure conditions such as high-rise buildings, large-volume concrete, or pumped pouring, the existing U-shaped clamps and U-shaped nuts mainly rely on the axial clamping force of the threaded pair to clamp the formwork. Their connection form is a single axial locking. Under the impact of concrete vibration or pumping, the U-shaped clamps or pads are prone to lateral slippage, deflection, or even loosening, resulting in the loss of local locking force, which in turn leads to serious quality and safety accidents such as formwork bulging, formwork running, or even formwork bursting. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a mountain-shaped locking structure for anti-loosening positioning, which solves the problem that the mountain-shaped clip or pad is prone to lateral slippage, deflection or even loosening, resulting in local loss of locking force, which in turn leads to serious quality and safety accidents such as mold bulging, mold running or even mold bursting.

[0006] (II) Technical Solution:

[0007] To achieve the above objectives, this utility model provides the following technical solution: a mountain-shaped locking structure for anti-loosening positioning, comprising a horizontally arranged screw, wherein the outer surface of the screw is threaded with multiple fixing components;

[0015] (III) Beneficial Effects:

[0016] Compared with the prior art, the present invention provides a method with the following beneficial effects:

[0025] This utility model provides a technical solution:

[0026] Please see Figures 1-4 A mountain-shaped locking structure for preventing loosening and positioning includes a horizontally arranged screw 1, with multiple fixing components threaded onto the outer surface of the screw 1;

[0027] The fixing component includes a mountain-shaped clip 2 and a mountain-shaped nut 3. A pad 4 is provided between the mountain-shaped clip 2 and the mountain-shaped nut 3. Rectangular grooves 5 are respectively opened through both sides of the mountain-shaped clip 2 and the pad 4. A connector is provided in the rectangular groove 5, and the connector is located at the end of the mountain-shaped nut 3 away from the mountain-shaped clip 2. A clamping part is provided at the bottom of the connector.

[0028] The screw 1 passes through the back ribs or joists on both sides of the concrete formwork to bear the lateral pressure generated during the concrete pouring process. Multiple fixing components on the outer surface of the screw 1 are distributed on the outside of the formwork to achieve multi-point uniform force distribution and reliable locking.

[0029] The U-shaped clamp 2 of the fixing component is a metal component with a central threaded through hole. It is sleeved on the tie rod 1. The U-shaped open end is used to abut against the wooden or steel back rib on the outside of the template to transmit the locking force. The pad 4 is an outer rectangle with an inner circle. It is set between the U-shaped clamp 2 and the U-shaped nut 3 to increase the force-bearing area and avoid local pressure damage or stress concentration of the template during the tightening process of the U-shaped nut 3. The U-shaped nut 3 forms a threaded engagement with the screw rod 1. It moves along the axial direction of the screw rod 1 through rotation, gradually pressing the pad 4 and the U-shaped clamp 2, thereby achieving effective clamping and fixing of the template system.

[0030] To further improve the stability of the fixing component under high vibration and high load conditions and prevent the mountain-shaped clip 2 and the pad 4 from lateral slippage, deflection or loosening after locking, rectangular grooves 5 are respectively provided on the left and right sides of the mountain-shaped clip 2 and the pad 4. The rectangular grooves 5 penetrate the side walls of the mountain-shaped clip 2 and the pad 4 in a direction perpendicular to the axis of the screw 1. A connector is inserted into the rectangular groove 5, the length of which spans the combined thickness of the mountain-shaped clip 2 and the pad 4, and the bottom two ends are exposed to achieve lateral through connection. The connector is set in the outer space of the mountain-shaped nut 3 to ensure the limitation of lateral displacement of the mountain-shaped nut 3 and the mountain-shaped clip 2.

[0031] In use, insert the mountain-shaped clip 2 into the tie rod 1, adjust it to an appropriate position on the outside of the template, tighten the mountain-shaped nut 3 to press the pad 4, and achieve the main locking. Then, insert the connector into the rectangular groove 5 and cover the mountain-shaped nut 3, and fix it to the surrounding stable structure through the bottom clamp. The connector restricts the lateral displacement of the mountain-shaped clip 2 and the pad 4. The cooperation between the rectangular groove 5 and the connector prevents the component from rotating around the screw 1. Through threaded locking and external clamping, the vibration resistance and anti-loosening ability are significantly improved.

[0032] The connector includes three horizontally arranged fixed rods 6, with fixed plates 7 fixedly connected between adjacent fixed rods 6. Elastic rods 8 are fixedly connected to both ends of the bottom of the multiple fixed rods 6, and elastic plates 9 are fixedly connected to the bottom of the elastic rods 8. The elastic plates 9 include a bending part 10 and a guide part 11. The bending part 10 is fixedly connected to the end of the elastic rod 8, and the end of the bending part 10 away from the elastic plate is fixedly connected to the guide part 11. The bending part 10 and the guide part 11 match the cross-sectional dimensions of the rectangular groove 5.

[0033] The clamping component includes double-sided clamping plates 12. The inner walls of the double-sided clamping plates 12 are in contact with the bending portion 10. The double-sided clamping plates 12 include arc-shaped spring pieces 13 and two elastic rods 14. The two ends of one side of the arc-shaped spring piece 13 are connected to the two elastic rods 14. Guide parts 15 are fixedly connected to the two elastic rods 14 respectively. The two sides of the two elastic rods 14 extend to their adjacent ends and are in contact with the outer wall of the bending portion 10. The arc-shaped spring piece 13 and the two elastic rods 14 are integrally formed.

[0034] Three horizontally arranged fixing rods 6 are arranged in parallel and extend in a direction perpendicular to the axis of the tie rod 1. Adjacent fixing rods 6 are rigidly connected by at least one fixing plate 7. The fixing plate 7 can be a rectangular or trapezoidal metal plate and is fixed to the middle or end of the two fixing rods 6 by welding, riveting or integral molding process to enhance the bending and torsional stiffness of the overall structure and ensure that the connector does not twist or deform under force. The elastic rods 8 at both ends of the bottom of the fixing rods 6 extend downward in the vertical direction. The material is preferably spring steel or alloy material with excellent elasticity, which has good resilience and fatigue strength. Multiple elastic rods 8 are symmetrically contracted and distributed to jointly form the lower elastic support structure of the connector.

[0035] The bottom of the elastic rod 8 is fixedly connected to an elastic sheet 9, which includes a bending part 10 and a guide part 11. The bending part 10 is a trapezoidal elastic bending section with a certain elastic deformation capacity. It can produce slight opening or compression during assembly, which is convenient for cooperating with the clamping parts. The guide part 11 is in the shape of an inclined plate. In the initial state, the guide part 11 is located inside the rectangular groove 5 due to its elastic contraction state, and a part of it extends into the range of the rectangular groove 5. By pressing down, the guide part 11 is squeezed, which drives the bending part 10 and the elastic rod 8 to achieve parallelism between the bending part 10 and the elastic rod 8 and the rectangular groove 5.

[0036] The clamping component is a double-sided clamping plate 12 structure. Its inner wall is in contact with the outer wall of the bent portion 10 of the elastic sheet 9, forming a tight contact fit. The double-sided clamping plate 12 securely locks the connector through elastic clamping force. The specific structure includes an arc-shaped spring sheet 13 and two elastic rods 14. The arc-shaped spring sheet 13 is located in the middle of the clamping component and is concave arc-shaped, providing deformation support for the two elastic rods 14. The two elastic rods 14 are respectively connected to the ends on both sides of the arc-shaped spring sheet 13. The free ends of the two elastic rods 14 extend towards each other and form extension arms at their adjacent ends. The two extension arms are fully in contact with the outer wall of the bent portion 10 in the connector when they are parallel. When the double-sided clamping plate 12 is pressed into the connector, elastic compression is generated between the elastic rods 14 and the bent portion 10, forming a self-locking force to prevent the clamping component from loosening during vibration.

[0037] The arc-shaped spring 13 and the two elastic rods 14 are made of high-elasticity metal sheet by stamping or bending, and have good integrity and fatigue life.

[0038] In practical use, the working principle of this utility model is as follows:

[0039] A horizontally positioned tie rod 1 passes through the back ribs or keel structures on both sides of the concrete formwork, with both ends exposed on the outside of the formwork. Multiple fixing components are spaced axially on the outer surface of the tie rod 1. Aligned rectangular slots 5 are opened on the left and right sides of the mountain-shaped clip 2 and the pad 4, respectively. The slots extend in a direction perpendicular to the axis of the tie rod 1. The guide part 11 passes through the rectangular slot 5 and the outer wall of the mountain-shaped nut 3. When the guide part 11 is inserted, the guide part 11 is squeezed by downward pressure, which causes the bending part 10 and the elastic rod 8 to undergo elastic deformation, so that the guide part 11 is parallel and attached to the inner wall of the rectangular slot 5. The double clamping plates 12 are pressed against the connector. The elastic rod 14 and the bending part 10 undergo elastic deformation at the moment of contact, and rebound quickly after passing the contact surface, forming a surface contact elastic self-locking, which effectively prevents the clamping parts from loosening during vibration.

[0040] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
