Description

Technical Field

[0001] This utility model relates to the field of steel reinforcement construction, specifically a positioning trestle structure for upper-layer steel reinforcement. Background Technology

[0002] In traditional building construction, the upper layer of reinforcing bars in reinforced concrete structures is typically fixed using manual tying or simple support structures. These methods suffer from inefficiency, poor stability, and susceptibility to deformation, making it difficult to precisely control the position of the upper layer of reinforcing bars and affecting the structure's load-bearing capacity and durability. To address these issues, existing technologies use stirrup structures to position and support the upper layer of reinforcing bars. However, stirrups generally need to be customized according to the dimensions of the concrete structure being constructed, making it difficult to meet the positioning and support needs of reinforcing bars of different heights and spacings, resulting in significant inconvenience in practical use. Utility Model Content

[0003] The purpose of this utility model is to provide a positioning stirrup structure for upper-layer reinforcing bars, which can solve the technical problem that existing stirrups are difficult to use for reinforcing bars of different heights and spacings. By cooperating with transverse and longitudinal reinforcing bars, it can achieve positioning support for reinforcing bars of different spacings and heights, improve the adaptability to concrete buildings of different sizes, and greatly improve the convenience of actual use.

[0004] To achieve the above objectives, this utility model employs the following technical solution:

[0005] A positioning trestle structure for upper-layer reinforcing bars includes a crossbar with symmetrically slidably connected sliding sleeves on both sides. Each sliding sleeve has a supporting foot at its bottom. One end of each sliding sleeve has a groove for engaging with longitudinal reinforcing bars, and the other end has a slot for engaging with transverse reinforcing bars. A sliding block is slidably connected vertically to one side wall of the slot. A pressure rod for driving the sliding block is provided on the slot. The bottom of the sliding block has a rotating groove, and the top of the rotating groove is rotatably connected to a pressure plate for engaging with the top of the transverse reinforcing bars. A torsion spring is provided between the pressure plate and the rotating groove. A fixing sleeve is provided at the bottom of the sliding sleeve, and the supporting foot is threaded into the inside of the fixing sleeve.

[0006] Furthermore, a sliding hole is provided on one side wall of the slot, the slide block is slidably connected in the sliding hole, and the pressure rod passes through the sliding hole and is connected to the slide block.

[0007] Furthermore, the pressure rod is threaded to the side wall of the slot, and the bottom end of the pressure rod passes through the sliding hole and is rotatably connected to the slide block.

[0008] Furthermore, the sliding sleeve has a fixed block inside, and the two ends of the crossbar are symmetrically rotatably connected to adjusting rods, which pass through the fixed block and are threadedly connected to it.

[0009] Furthermore, the side wall of the crossbar is symmetrically provided with limiting blocks, and the inner wall of the sliding sleeve is symmetrically provided with limiting grooves, and the limiting blocks are slidably connected in the limiting grooves.

[0010] Furthermore, the bottom of the pressure plate is arc-shaped.

[0011] Furthermore, the bottom of the support foot is provided with multiple inclined support rods.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. The structure of this utility model has symmetrical sliding sleeves on both sides of the crossbar. The bottom of the sliding sleeve is provided with a fixed sleeve. The support foot is threaded into the inside of the fixed sleeve. One end of the sliding sleeve is provided with a groove for cooperating with the longitudinal steel bar, and the other end of the sliding sleeve is provided with a slot for cooperating with the transverse steel bar. This structure allows the grooves at one end of the sliding sleeves on both sides to cooperate and fix with the longitudinal steel bar, and the slots at the other end of the sliding sleeves to cooperate and fix with the transverse steel bar, thereby satisfying the support of steel bars with different spacing. At the same time, by rotating the support foot relative to the fixed sleeve at the bottom of the sliding sleeve, the sliding sleeve can be raised to different heights to cooperate with the transverse and longitudinal steel bars, which improves the adaptability to the construction of concrete buildings of different sizes, eliminates the need for specific customization, and greatly improves the convenience of actual use.

[0014] 2. A sliding block is vertically connected to one side wall of the slot. The slot has a pressure rod that drives the sliding block to slide. The bottom of the sliding block has a rotating groove. The top of the rotating groove is rotatably connected to a pressure plate that is used to engage with the top of the transverse reinforcing bar. A torsion spring is provided between the pressure plate and the rotating groove. With this structure, when the slot and the transverse reinforcing bar are fixedly engaged, the sliding block is slid upward to insert the transverse reinforcing bar into the slot from the top. During this process, the transverse reinforcing bar contacts the top of the pressure plate and drives it to rotate until the pressure plate rotates into the interior of the rotating groove. The transverse reinforcing bar then smoothly enters the bottom of the slot. At this point, the pressure plate loses the compression of the transverse reinforcing bar and, under the action of the torsion spring, resets and rotates to the top of the rotating groove. Sliding the sliding block downward makes the bottom of the pressure plate contact the top of the transverse reinforcing bar, thereby achieving the clamping and fixing of the transverse reinforcing bar. This makes the fixed connection between the slot and the transverse reinforcing bar more secure and further improves the stability of supporting and positioning the upper reinforcing bar.

[0023] Reference Figure 1 and Figure 2This utility model describes a positioning trestle structure for upper-layer reinforcing bars. The main structure includes a horizontal bar 1, typically made of metal to ensure sufficient structural strength. Sliding sleeves 2 are symmetrically slidably connected to both sides of the horizontal bar 1, slidingly fitted onto the outside of the horizontal bar 1 to allow for lateral adjustment of its position relative to the horizontal bar 1. Support feet 3 are provided at the bottom of the sliding sleeves 2, supporting the horizontal bar 1 and the sliding sleeves 2 to ensure effective support and positioning of the upper-layer reinforcing bars. One end of the sliding sleeve 2 is fixed with a groove 5 for use with longitudinal reinforcing bars 4, either welded or integrally formed. The longitudinal section of the groove 5 is arc-shaped, allowing for better contact with the bottom of the longitudinal reinforcing bars 4, achieving effective support for the longitudinal reinforcing bars 4. The other end of the sliding sleeve 2 is fixed with a groove 7 for use with the transverse reinforcing bar 6 by welding or integral molding. Preferably, the longitudinal section of the groove 7 is U-shaped. The transverse reinforcing bar 6 enters the bottom of the groove 7 from the opening at the top of the U-shape, realizing a stable fit between the groove 7 and the transverse reinforcing bar 6. This structure allows for adjustment of the spacing between the grooves 5 on the two sliding sleeves 2 when the spacing of the two longitudinal reinforcing bars 4 in different concrete structures is different. This enables adaptive adjustment for upper reinforcing bars with different spacings. A sliding seat 8 is vertically slidably connected to one side wall of the groove 7. The groove 7 is provided with a pressure rod 9 to drive the sliding seat 8 to slide. The vertical position of the sliding seat 8 is adjusted by the pressure rod 9. The bottom of the sliding seat 8 is provided with a rotating... The groove 10, preferably rectangular, is rotatably connected at its top to a pressure plate 11 that engages with the top of the transverse reinforcing bar 6 via a pin or hinge. Since the pressure plate 11 is rotatably connected to the top of the groove 10, it can rotate upwards to a horizontal position at most. This arrangement allows the sliding block 8 to slide downwards, driving the pressure plate 11 to slide downwards, thereby pressing and fixing the transverse reinforcing bar 6, improving the pressing and fixing effect. A torsion spring 12 is provided between the pressure plate 11 and the groove 10. Under the action of the torsion spring 12, the pressure plate 11 remains in a horizontal position. The transverse reinforcing bar 6 slides upwards from the top of the slot 7 onto the sliding block 8, providing sufficient space for the rotation of the pressure plate 11. After entering the slot 7, the transverse steel bar 6 contacts the top of the pressure plate 11 and drives the pressure plate 11 to rotate downwards. During this process, the torsion spring 12 is compressed until the pressure plate 11 is fully rotated into the rotating groove 10. Then, the transverse steel bar 6 can smoothly enter the bottom of the slot 7. At this time, the pressure plate 11 loses the compression of the transverse steel bar 6 and rotates in the opposite direction to the horizontal direction under the action of the torsion spring 12. Then, the sliding block 8 slides downwards, and the sliding block 8 drives the pressure plate 11 to move downwards until the bottom of the pressure plate 11 contacts the top of the transverse steel bar 6, thereby achieving the pressing and fixing of the transverse steel bar 6. This structure makes the cooperation between the transverse steel bar 6 and the slot 7 more convenient and the pressing and fixing of the transverse steel bar 6 more secure, further improving the firmness of the trestle structure in supporting and positioning the upper steel bars.The bottom of the sliding sleeve 2 is fixed with a fixing sleeve 13 by welding or integral molding. The support foot 3 is threaded into the inside of the fixing sleeve 13. By rotating the support foot 3, the height of the fixing sleeve 13 and the sliding sleeve 2 can be vertically adjusted relative to the support foot 3. This allows the sliding sleeve 2 to be used smoothly with upper-layer steel bars of different heights, greatly improving its adaptability to steel bars in concrete structures of different sizes. It eliminates the need for customization for each project, significantly improving the convenience of practical use.

[0024] Preferred, refer to Figure 3 and Figure 4 The slot 7 has a through sliding hole 14 on one side wall. The slide block 8 is slidably connected in the sliding hole 14. The pressure rod 9 passes through the sliding hole 14 and is connected to the slide block 8. The sliding hole 14 is designed to guide the vertical sliding of the slide block 8. At the same time, the sliding hole 14 can prevent the slide block 8 from occupying the internal space of the slot 7, so as not to block the transverse steel bar 6 from entering the slot 7, thus improving the smoothness of the fit between the slot 7 and the transverse steel bar 6.

[0025] Preferably, the pressure rod 9 is threaded to the side wall of the slot 7, and the bottom end of the pressure rod 9 passes through the sliding hole 14 and is rotatably connected to the slide block 8 through a bearing. With this structure, the slide block 8 can be driven to slide downward along the sliding hole 14 by rotating the pressure rod 9 under the action of the threaded connection. After sliding to the designated position, the slide block 8 is kept in the designated position under the action of the threaded connection, which improves the robustness and ease of use of the sliding adjustment structure of the slide block 8.

[0026] Preferred, refer to Figure 5 The sliding sleeve 2 has a fixed block 15 inside by welding or integral molding. The two ends of the crossbar 1 are symmetrically connected to the adjusting rod 16 by bearings. The adjusting rod 16 passes through the fixed block 15 and is threadedly connected to it. With this structure, when the adjusting rod 16 is rotated, the fixed block 15 and the sliding sleeve 2 are driven to slide relative to the crossbar 1 under the action of the threaded connection, making the sliding adjustment of the sliding sleeve 2 relative to the crossbar 1 smoother and more convenient.

[0027] Preferably, symmetrical limiting blocks 17 are fixed on the side wall of the crossbar 1 by welding or integral molding, and symmetrical limiting grooves 18 are provided on the inner wall of the sliding sleeve 2. The limiting grooves 18 are recessed inward from the inner wall of the sliding sleeve 2. The limiting blocks 17 are slidably connected in the limiting grooves 18. The sliding cooperation between the limiting blocks 17 and the limiting grooves 18 makes it difficult for the sliding sleeve 2 to rotate relative to the crossbar 1 when it slides laterally. This makes the sliding structure of the sliding sleeve 2 relative to the crossbar 1 more stable and the support and positioning structure for the upper reinforcing bars more stable.

[0028] Preferably, the bottom of the pressure plate 11 is arc-shaped. The arc-shaped structure allows the bottom of the pressure plate 11 to make closer contact with the top of the transverse steel bar 6, thereby improving the clamping and fixing effect on the transverse steel bar 6.

[0029] Preferably, the bottom of the support leg 3 is fixed with multiple inclined support rods 19 by welding or integral molding. The multiple inclined support rods 19 increase the contact area between the support leg 3 and the building below, making the trestle structure more stable and less prone to tilting or shaking, thus further improving the stability of the support.

[0030] Working Principle: This invention features symmetrical sliding sleeves 2 on both sides of a crossbar 1. A fixed sleeve 13 is located at the bottom of each sleeve 2, and a support foot 3 is threaded into the fixed sleeve 13. One end of each sleeve 2 has a groove 5 for engaging with longitudinal reinforcing bars 4, and the other end has a slot 7 for engaging with transverse reinforcing bars 6. This structure allows the grooves 5 at one end of each sleeve 2 to smoothly engage with and fix the longitudinal reinforcing bars 4, while the slot 7 at the other end engages with and fixes the transverse reinforcing bars 6. This satisfies the need for supporting reinforcing bars with different spacings. Simultaneously, by rotating the support foot 3 relative to the fixed sleeve 13 at the bottom of the sleeve 2, the sleeve 2 can rise to different heights to engage with the transverse and longitudinal reinforcing bars 6 and 4, improving adaptability to concrete construction of different sizes. It eliminates the need for custom-designed components, greatly enhancing ease of use. A vertical sliding connection is also present on one side wall of the slot 7. The slide block 8 and the slot 7 are equipped with a pressure rod 9 for driving the slide block 8 to slide. The bottom of the slide block 8 is equipped with a rotating groove 10. The top of the rotating groove 10 is rotatably connected to a pressure plate 11 for use with the top of the transverse steel bar 6. A torsion spring 12 is provided between the pressure plate 11 and the rotating groove 10. With this structure, when the slot 7 and the transverse steel bar 6 are fixedly engaged, the slide block 8 is slid upward to insert the transverse steel bar 6 from the top of the slot 7 into the slot 7. During this process, the transverse steel bar 6 contacts the top of the pressure plate 11 and drives it to rotate until the pressure plate 11 rotates into the interior of the rotating groove 10. Then, the transverse steel bar 6 smoothly enters the bottom of the slot 7. At this time, the pressure plate 11 loses the compression of the transverse steel bar 6 and is reset and rotated to the top of the rotating groove 10 under the action of the torsion spring 12. Then, the slide block 8 is slid downward to make the bottom of the pressure plate 11 contact the top of the transverse steel bar 6, thereby realizing the pressing and fixing of the transverse steel bar 6. This makes the fixed connection between the slot 7 and the transverse steel bar 6 more secure and further improves the stability of supporting and positioning the upper steel bar.
