Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a building formwork support structure with adjustable top support. Background Technology

[0002] In the field of building construction, formwork support structures are the core auxiliary system for ensuring the quality of concrete pouring and construction safety. Whether it is the pouring of floor slabs in high-rise buildings, the construction of bridge piers, or the roof work of underground garages, they all rely on them to achieve stable erection and precise positioning of formwork. Their performance directly affects the project progress, structural accuracy, and construction costs.

[0003] The traditional formwork support structure widely used in the industry is mainly a combination of round pipes and timber, supplemented by through-wall screws, U-shaped clips and other connectors for reinforcement.

[0004] However, existing traditional systems mostly rely on manual insertion or bolt tightening to achieve height adjustment, which is cumbersome and requires multiple people to work together, resulting in low adjustment efficiency. They also lack effective fine-tuning mechanisms and are difficult to control with millimeter-level precision, leading to large deviations in formwork elevation and verticality, which affects the forming accuracy of concrete components. To address these issues, a building formwork support structure with an adjustable top support is proposed. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a building formwork support structure with an adjustable top support, which aims to improve the problem of the lack of an effective fine-tuning mechanism in the prior art.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a building formwork support structure with an adjustable top support, comprising a support rod one, a support rod two inserted into the inner wall of the top of the support rod one, a reinforcing guide rod fixedly connected to the top of the support rod two, an upper support rod slidably connected through the outer wall of the reinforcing guide rod, a top support body inserted into the inner wall of the top of the upper support rod, a rotating base rotatably connected to the inner wall of the top of the support rod two, a threaded rod fixedly connected to the top of the rotating base, a locking block fixedly connected to the outer arc surface of the bottom of the rotating base, a collar slidably connected through the outer wall of the rotating base, a locking groove formed on the inner side wall of the collar, a handle fixedly connected to the outer wall of the collar, and a trajectory groove formed on the outer arc surface of the support rod two.

[0007] As a further description of the above technical solution: A semi-circular block is hinged to the inner wall of the middle section of the support rod one. A connecting plate is elastically connected to the inner wall of the middle section of the support rod one through a limiting spring. Insert rods are fixedly connected to the bottom of both sides of the connecting plate. A baffle is fixedly connected to the outer wall of the connecting plate. A slot is opened at the top of the semi-circular block. A limiting groove is opened on the outer arc surface of the support rod two.

[0008] As a further description of the above technical solution: The outer wall of the threaded rod is threaded to the bottom inner wall of the upper support rod.

[0009] As a further description of the above technical solution: The card block engages with the inner wall of the card slot.

[0010] As a further description of the above technical solution: The grip is in contact with the inner wall of the track groove.

[0011] As a further description of the above technical solution: One end of the limiting spring is fixedly connected to the inner wall of the support rod, and the other end of the limiting spring is fixedly connected to the top of the connecting plate.

[0012] As a further description of the above technical solution: The connecting plate is slidably connected to the inner wall of the first support rod, the insert rod is slidably connected to the inner wall of the first support rod, and the baffle is slidably connected to the inner wall of the first support rod.

[0013] As a further description of the above technical solution: The insertion rod is engaged with the inner wall of the slot, and the semi-circular block is engaged with the inner wall of the limiting groove.

[0014] This utility model has the following beneficial effects: 1. In this utility model, through the fine-tuning function of the threaded rod, combined with the convenient cooperation of the collar, the locking block and the locking groove, the operator can rotate the collar by holding the handle, and use the locking of the locking block and the locking groove to transmit the torque to drive the threaded rod to rotate, so as to realize the millimeter-level height adjustment of the top support body. Moreover, when making fine adjustments over a long distance, the locking state can be switched by raising and lowering the collar to achieve continuous adjustment, effectively controlling the deviation of the template elevation and verticality, and avoiding the forming defects of concrete components caused by inaccurate positioning.

[0015] 2. In this utility model, the support height can be roughly adjusted quickly by the plug-in telescopic cooperation of support rod one and support rod two and the semi-circular block locking structure, without the need for multiple people to work together or complex tools. It is especially suitable for the formwork erection needs of different scenarios such as high-rise building floor slabs and bridge piers, and greatly shortens the height calibration time.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1-3This utility model provides an embodiment of a building formwork support structure with an adjustable top support, including a support rod 1. The support rod 1 serves as the basic load-bearing component of the support structure and is made of high-strength steel to ensure overall stability. Its bottom is in direct contact with the ground. A support rod 2 is inserted into the inner wall of the top of the support rod 1. This insertion method facilitates the relative expansion and contraction between the two, while ensuring a tight connection through precise dimensional matching. A reinforcing guide rod 3 is fixedly connected to the top of the support rod 2. Four sets of reinforcing guide rods 3 are provided to enhance the guiding accuracy when the upper support rod 4 slides. To prevent misalignment, an upper support rod 4 is slidably connected to the outer wall of the reinforcing guide rod 3. The upper support rod 4 can slide along the axial direction of the reinforcing guide rod 3, providing space for height adjustment of the top support body 5. The top support body 5 is inserted into the inner wall of the top of the upper support rod 4, and the top support body 5 directly contacts the building formwork. Its top surface is polished to ensure a good fit with the formwork. A rotating base 7 is rotatably connected to the inner wall of the top of the second support rod 2. The rotating base 7 is connected to the second support rod 2 through a bearing, enabling flexible rotation and reducing friction loss. A threaded rod 6 is fixedly connected to the top of the rotating base 7. The grooved rod 6 and the rotating base 7 are fixed by welding to ensure synchronous rotation. A locking block 8 is fixedly connected to the outer arc surface of the bottom of the rotating base 7. The locking block 8 has a rectangular structure, and its size matches the locking groove 10 to achieve stable engagement. A collar 9 is slidably connected through the outer wall of the rotating base 7. The collar 9 can slide up and down along the axial direction of the rotating base 7 to control the engagement state of the locking block 8 and the locking groove 10. The inner side wall of the collar 9 has locking grooves 10, the number and distribution of which correspond to the locking block 8 to ensure precise positioning during engagement. A handle 11 is fixedly connected to the outer wall of the collar 9, and the surface of the handle 11 is... It has anti-slip texture, making it easy for operators to grip and apply force to rotate the collar 9. The outer arc surface of the support rod 2 has a track groove 12, which extends along the axial direction of the support rod 2, providing a limited path for the sliding of the handle 11. The outer wall of the threaded rod 6 is threaded to the bottom inner wall of the upper support rod 4. The rotation of the threaded rod 6 can drive the upper support rod 4 to rise and fall axially, realizing fine adjustment of the top support height. The locking block 8 is locked on the inner wall of the locking groove 10. This locking structure can transmit the rotational torque when adjustment is needed, and keep the parts relatively fixed when no adjustment is needed. The handle 11 is in contact with the inner wall of the track groove 12.

[0020] Reference Figure 1 , Figure 4 , Figure 5A semicircular block 13 is hinged to the inner wall of the middle section of support rod 1. The semicircular block 13 is connected to support rod 1 via a pin, allowing it to rotate around the hinge point at a certain angle. A connecting plate 15 is elastically connected to the inner wall of support rod 1 via a limiting spring 14. The limiting spring 14 is always in a stretched state, providing downward elastic pressure to the connecting plate 15. Insert rods 16 are fixedly connected to the bottom of both sides of the connecting plate 15. The insert rods 16 and the connecting plate 15 are integrally formed, improving the overall strength of the component. A baffle 17 is fixedly connected to the outer wall of the connecting plate 15. The baffle 17 is used to prevent dust from entering the top of the connecting plate 15 and to avoid damaging the limiting spring 14. A slot 18 is opened on the top of the semicircular block 13. The shape of the slot 18 is adapted to the insert rod 16 to ensure that the insert rod 16 can effectively limit the semicircular block 13 after insertion. A limiting groove is opened on the outer arc surface of support rod 2. 19. The limiting groove 19 is evenly distributed in a ring on the outer wall of the second support rod 2. It is used to cooperate with the semi-circular block 13 to achieve the height positioning of the second support rod 2. One end of the limiting spring 14 is fixedly connected to the inner wall of the first support rod 1, and the other end of the limiting spring 14 is fixedly connected to the top of the connecting plate 15. Through the opposing extrusion force between the limiting spring 14 and the inner wall of the first support rod 1, the insertion rod 16 is always locked in the inner wall of the slot 18 without being affected by external force. At the same time, the semi-circular block 13 is always locked in the inner wall of the limiting groove 19 without being affected by external force. The connecting plate 15 is slidably connected to the inner wall of the first support rod 1, the insertion rod 16 is slidably connected to the inner wall of the first support rod 1, the baffle 17 is slidably connected to the inner wall of the first support rod 1, the insertion rod 16 is locked in the inner wall of the slot 18, and the semi-circular block 13 is locked in the inner wall of the limiting groove 19.

[0021] Working principle: When it is necessary to raise or lower the height of support rod 1 and support rod 2, push the connecting plate 15 upward and slide it upward along the inner wall of support rod 1, thereby causing the insert rod 16 to disengage from the slot 18 of the semicircular block 13. At this time, the semicircular block 13 loses the limitation of the insert rod 16 and can rotate freely around the hinge point, releasing the lock on support rod 2. The operator can directly pull or press down on support rod 2, causing it to extend and retract along the insertion point on the top inner wall of support rod 1 until the approximate target height is reached. Then, rotate the semicircular block 13 inward to engage with the corresponding limiting groove 19, and then release the connecting plate 15. The limiting spring 14 returns to its stretched state, pull the connecting plate 15 and insert rod 16 to reset, and insert rod 16 re-engages into the slot 18 of the semicircular block 13, forcing the semicircular block 13 to engage back into the corresponding limiting groove 19 of support rod 2, thus completing the height locking of support rod 1 and support rod 2.

[0022] When fine-tuning of the top support body 5 is required, the inner wall groove 10 of the collar 9 engages with the locking block 8. The collar 9 can be rotated manually along the defined path of the track groove 12 by rotating the handle 11. The torque is transmitted through the brief contact between the locking block 8 and the groove 10, causing the rotating base 7 and the threaded rod 6 to rotate synchronously. Since the threaded rod 6 and the upper support rod 4 are threadedly connected, the rotation of the threaded rod 6 is converted into the upper support rod 4 sliding axially along the reinforcing guide rod 3. When the handle 11 is rotated clockwise, the threaded rod 6 drives the upper support rod 4 to rise, and the top support body 5 rises accordingly; when rotated counterclockwise, the upper support rod 4 falls, and the top support body 5 falls. When continuous fine-tuning is required to cover a longer stroke, the handle 11 can be lifted to disengage the groove 10 on the collar 9 from the locking block 8. The collar 9 can be rotated on the upper part of the outer wall of the rotating base 7 to move the handle 11 to the leftmost or rightmost side of the track groove 12. Then the collar 9 can be lowered to engage the groove 10 with the outer wall of the locking block 8. The threaded rod 6 can be rotated repeatedly over short distances in this manner.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
