Description

Technical Field

[0001] This utility model relates to the field of auxiliary structure technology in building construction, and in particular to an adjustable concrete formwork support structure. Background Technology

[0002] In concrete construction, formwork support structures play a crucial role. These structures must withstand the immense pressure and lateral forces during concrete pouring to ensure the stability and shape accuracy of the formwork, thereby guaranteeing the quality of the concrete structure. However, traditional concrete formwork support structures have the following shortcomings in supporting concrete:

[0003] Since the height and width of traditional support structures are usually fixed, they are difficult to adapt to the construction needs of concrete components with different building structures, different floor heights and different cross-sectional sizes. When encountering complex and ever-changing construction scenarios, it is necessary to prepare support structures of various specifications, which not only increases material and storage costs, but also makes the management of the construction site complicated and cumbersome.

[0004] In addition, traditional support structures, when used with bolts to support concrete formwork, are prone to loosening under the influence of any external factors. This can lead to the support structure sinking, swaying, and even deformation or collapse, posing a significant threat to the safety of construction workers and the quality of the construction project. Utility Model Content

[0005] This utility model discloses an adjustable concrete formwork support structure. As the height of the support rod is adjusted, the top plate at the top also rises or falls accordingly. The top plate is adjusted to a position that is in close contact with the bottom of the concrete formwork. Since the top plate is an inverted U-shaped structure, it can provide stable support for the right-angle position of the concrete formwork, ensuring that there is no gap or shaking between the top plate and the formwork, so that the support structure can effectively bear the load of the formwork and concrete pouring process.

[0006] In a first aspect, this disclosure provides an adjustable concrete formwork support structure, specifically comprising: a support structure, the support structure being composed of a stabilizing tube, a connecting plate, a support rod, and a top plate; an adjustment structure being installed between the stabilizing tube and the support rod, the adjustment structure being composed of a positioning seat and a threaded rod; an anti-loosening structure being installed on the inner side of the stabilizing tube, the anti-loosening structure being composed of an anti-loosening seat, a first positioning rod, and a locking block; and a positioning mechanism being installed on the outer side of the stabilizing tube with bolts, the positioning mechanism being composed of a stabilizing shell, a positioning inclined block, and a second positioning rod.

[0007] Furthermore, a stabilizing plate is provided at the bottom of the stabilizing tube, a set of through holes are opened at the corner of the stabilizing plate, and a sliding groove is opened on one side of the stabilizing tube. The sliding groove has a T-shaped structure.

[0008] Furthermore, a connecting plate is installed on the outer side of the upper part of the stabilizing tube, and the connecting plate has a set of vertical through holes.

[0009] Furthermore, a vertical support rod is installed on the inner side of the stabilizing tube. Both the stabilizing tube and the support rod are rectangular structures. A top plate is provided above the support rod, and the top plate is an inverted U-shaped structure.

[0010] Furthermore, a positioning seat is installed inside the stabilizing tube body with bolts. A rotating hole is opened in the middle of the positioning seat, and a smooth positioning protrusion is provided at the bottom of the threaded rod. The positioning protrusion corresponds to the rotating hole of the positioning seat, and the threaded rod passes through the interior of the rotating hole with the positioning protrusion.

[0011] Furthermore, the outer side of the anti-loosening seat is provided with a set of arc protrusions, which are evenly distributed in a ring array on the outer side of the anti-loosening seat. A first positioning rod is provided at the bottom of the anti-loosening seat. A positioning groove corresponding to the first positioning rod is provided inside the stabilizing tube. The first positioning rod extends into the interior of the positioning groove. A transverse pressing plate is provided on one side of the anti-loosening seat.

[0012] Furthermore, a hexagonal groove is formed at the large end of the threaded rod. The hexagonal groove is used to connect to the existing hexagonal ratchet wrench. The outer side of the locking block has a hexagonal structure. The locking block is installed inside the hexagonal groove. A locking groove corresponding to the anti-loosening seat is formed in the middle of the locking block. A support spring is installed on the outer side of the first positioning rod.

[0013] Furthermore, the stabilizing housing is bolted to the outer side of the stabilizing tube, and a positioning wedge is installed on the inner side of the stabilizing housing. A second positioning rod is provided on one side of the positioning wedge at the middle position. A sliding hole is opened in the middle of the stabilizing housing, and the second positioning rod passes through the interior of the sliding hole. A support spring is installed on the outer side of the second positioning rod.

[0014] Furthermore, a positioning groove is formed on the outer side of the second positioning rod, and a retaining spring is installed at the position of the positioning groove.

[0015] This utility model provides an adjustable concrete formwork support structure, which has the following beneficial effects:

[0016] The system consists of a sturdy tube, support rods, and a top plate that work together to support the concrete formwork. The rectangular structure of the sturdy tube and support rods allows for both circumferential positioning of the support rods and smooth vertical adjustment. A threaded rod that precisely engages with the rotating hole of the positioning seat allows for convenient and quick adjustment of the top plate height using a wrench with a ratchet. This accurately adapts to the support needs of concrete formwork of different heights. Whether it is the initial formwork erection during construction or the need to adjust the formwork height due to project changes, the system can be operated efficiently, greatly improving construction efficiency and reducing construction delays caused by inconvenient height adjustment.

[0017] By precisely controlling the height of each support point, quality problems such as uneven concrete pouring thickness and uneven surface caused by uneven formwork can be effectively avoided, thereby improving the forming quality of concrete structures, reducing the workload of later repairs and rectifications, and thus reducing construction costs.

[0018] The threaded rod is prevented from loosening by installing anti-loosening seats with pressing plates, which further enhances the stability of the support structure after adjustment, enabling it to withstand large vertical loads and lateral forces during concrete formwork and pouring, thus ensuring the safe progress of construction.

[0019] The positioning wedge with spring support positions the anti-loosening seat after it is pressed down. After the anti-loosening seat is pressed down, the threaded rod is unlocked, which makes it convenient for construction personnel to rotate the threaded rod again and adjust the height of the support structure.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0037] Example 1: Please refer to Figures 1 to 8 :

[0038] This utility model proposes an adjustable concrete formwork support structure, including: a support structure 1, which is composed of a stabilizing pipe 101, a connecting plate 102, a support rod 103, and a top plate 104. A stabilizing plate is provided at the bottom of the stabilizing pipe 101, and a set of through holes are opened at the corners of the stabilizing plate. When the stabilizing plate contacts the ground, it can increase the support strength of the support structure 1 and prevent the bottom of the support structure 1 from tilting. The through holes facilitate splicing with anchor bolts. A sliding groove with a T-shaped structure is opened on one side of the stabilizing pipe 101, allowing the head of a wrench to pass through the sliding groove and connect to the large end of a threaded rod 202. Using a wrench with a ratchet (as in existing technology), the threaded rod 202 is rotated. A connecting plate 102 is installed on the outer side of the stabilizing pipe 101. Workers need to use welding technology to achieve a stable splicing of the stabilizing pipe 101 and the connecting plate 102. The connecting plate 102 has a set of vertical through holes, which, in existing technology, assist in... After the support plate and connecting plate 102 overlap, the through hole is used to install a wedge key, allowing the connecting plate 102 to cooperate with the wedge key to stabilize the overlapping support plate. A vertical support rod 103 is installed on the inner side of the stabilizing tube 101. Both the stabilizing tube 101 and the support rod 103 are rectangular structures. The rectangular structure of the stabilizing tube 101 enables the circumferential positioning of the support rod 103. In addition, the stabilizing tube 101 also enables the vertical extension and retraction adjustment of the support rod 103. A top plate 104 is provided above the support rod 103. The top plate 104 has an inverted U-shaped structure. The inverted U-shaped top plate 104 can provide stable support for the right-angle position of the concrete formwork. The cooperation between the stabilizing tube 101 and the support rod 103 can achieve the effect of flexible adjustment of the height of the top plate 104. When the top of the top plate 104 contacts the bottom of the concrete formwork, the stabilizing tube 101, the support rod 103, and the top plate 104 can support the concrete formwork at different heights.

[0039] In this embodiment of the disclosure, reference is made to Figures 1 to 8As shown, an adjustment structure 2 is installed between the stabilizing pipe body 101 and the support rod 103. The adjustment structure 2 consists of a positioning seat 201 and a threaded rod 202. A positioning seat 201 is installed inside the stabilizing pipe body 101 with bolts. After the operator tightens the bolts with a screwdriver, the positioning seat 201 is stabilized. A rotating hole is opened in the middle of the positioning seat 201. A smooth positioning protrusion is provided at the bottom of the threaded rod 202. The positioning protrusion corresponds to the rotating hole of the positioning seat 201. The threaded rod 202 passes through the interior of the rotating hole with the positioning protrusion. The rotating hole of the positioning seat 201 and the smooth positioning protrusion achieve the effect of vertical and horizontal positioning of the threaded rod 202, so that the threaded rod 202 can rotate stably in place around the rotating hole of the positioning seat 201. The positioning seat 201 facilitates the disassembly and assembly of the threaded rod 202 during the positioning process. An anti-loosening structure 3 is installed on the inner side of the stabilizing pipe body 101. The anti-loosening structure 3 consists of an anti-loosening seat 301, a first positioning rod 302 and a locking block 303.

[0040] In this embodiment of the disclosure, reference is made to Figures 1 to 8 As shown, the outer surface of the anti-loosening seat 301 is provided with a set of arc-shaped protrusions, which are evenly distributed in a ring array on the outer surface of the anti-loosening seat 301. A first positioning rod 302 is provided at the bottom of the anti-loosening seat 301. A positioning groove corresponding to the first positioning rod 302 is provided inside the stabilizing tube 101. The first positioning rod 302 extends into the positioning groove. The positioning groove, in conjunction with the first positioning rod 302, achieves the effect of lateral positioning of the anti-loosening seat 301, allowing the anti-loosening seat 301 to move stably up and down inside the stabilizing tube 101. A horizontal pressing plate is provided on one side of the anti-loosening seat 301. Users can move the anti-loosening seat 301 up and down by pressing the pressing plate downwards with their fingers. When the anti-loosening seat 301 is manually moved downwards, the lock is engaged. To unlock the locking block 303, a hexagonal groove is opened at the large end of the threaded rod 202. The hexagonal groove is used to connect to the existing hexagonal ratchet wrench. The outer side of the locking block 303 is hexagonal. The locking block 303 is installed inside the hexagonal groove. At this time, the hexagonal groove can achieve the effect of hiding the installation position of the locking block 303 and circumferential positioning. A locking groove corresponding to the anti-loosening seat 301 is opened in the middle position of the locking block 303. A support spring is installed on the outer side of the first positioning rod 302. The support spring pushes the anti-loosening seat 301 and the locking groove to automatically engage. At this time, the locking block 303 can achieve the effect of circumferential positioning of the anti-loosening seat 301. Combined with the limiting structure of the locking block 303, the anti-loosening seat 301 and the locking block 303 cooperate with each other to achieve the effect of quick anti-loosening of the threaded rod 202.

[0041] In this embodiment of the disclosure, reference is made to Figures 1 to 8As shown, a positioning mechanism 4 is bolted to the outer side of the stabilizing tube 101. The positioning mechanism 4 consists of a stabilizing housing 401, a positioning wedge 402, and a second positioning rod 403. The stabilizing housing 401 is bolted to the outer side of the stabilizing tube 101, and a positioning wedge 402 is installed on the inner side of the stabilizing housing 401. The internal structure of the stabilizing housing 401 achieves circumferential positioning of the positioning wedge 402, allowing it to move stably laterally within the stabilizing housing 401. The stabilizing housing 401 can also position the positioning wedge 402 vertically. A second positioning rod 403 is located in the middle of one side of the positioning wedge 402. A sliding hole is made in the middle position, and the second positioning rod 403 passes through the interior of the sliding hole. A support spring is installed on the outside of the second positioning rod 403. When the pressing plate on one side of the anti-loosening seat 301 moves downward, it can squeeze the positioning inclined block 402 to one side. Then the pressing plate continues to move downward. At this time, the support spring pushes the positioning inclined block 402 to one side to reset and lock one side of the pressing plate. This makes it convenient for the construction personnel to rotate the threaded rod 202 after unlocking. A positioning groove is made on the outer side of the second positioning rod 403. A retaining spring is installed at the position of the positioning groove. The retaining spring realizes the positioning effect of positioning the moving position of the positioning inclined block 402 and the second positioning rod 403, and at the same time prevents the positioning inclined block 402 and the second positioning rod 403 from falling off.

[0042] Example 2, based on Example 1, with reference to Figures 1 to 8 As shown, construction workers can build a further supporting structure 1 on the basis of the supporting structure 1 according to the actual site conditions.

[0043] Example 2, based on Example 1, with reference to Figures 1 to 8 As shown, construction workers can pre-embed anchor bolts in the ground according to the actual site conditions.

[0044] The working principle of this embodiment:

[0045] In the basic preparation and initial installation steps, workers need to use welding technology to achieve a stable connection between the stabilizing pipe 101 and the connecting plate 102. Referring to the connection structure described in the instruction manual, workers assemble the entire assembly using wrenches. Based on the construction site plan, the workers determine the installation location of the support structure 1. If necessary, anchor bolts are pre-embedded in the ground, ensuring that the position and height of the anchor bolts meet the requirements, and that the threads are undamaged and free of debris. Workers then move the stabilizing pipe 101 of the support structure 1 to the installation location, ensuring that the stabilizing plate at the bottom of the stabilizing pipe 101 contacts the ground, ensuring that the four corners of the stabilizing plate are tightly fitted to the ground to increase the support area and stability. Then, the anchor bolts are passed through the insertion holes of the stabilizing plate and initially tightened with nuts, but not completely, to allow for subsequent fine-tuning of the support structure 1.

[0046] The installation and height adjustment steps for adjusting structure 2 are as follows: The construction worker, inside the stable pipe body 101, uses a screwdriver and bolts to securely install the positioning seat 201 at a suitable position, ensuring the rotation hole of the positioning seat 201 is accurately positioned and free of obstructions. The positioning protrusion at the bottom of the threaded rod 202 is aligned with the rotation hole of the positioning seat 201, and inserted so that the threaded rod 202 can rotate stably on the positioning seat 201 without lateral or vertical displacement. At this point, the head of a wrench with a ratchet can be passed through the T-shaped sliding groove of the stable pipe body 101 and engaged with the threaded rod. The hexagonal groove connection at the large end of 202 allows the construction worker to rotate a wrench and adjust the extension length of the threaded rod 202 according to the required support height. This causes the connected support rod 103 to move up and down within the stable pipe body 101. During the adjustment process, the distance from the top plate 104 to the ground can be measured at any time using existing measuring tools to ensure that the designed support height requirements are met. The user can use their fingers to pull the second positioning rod 403 to one side, so that the anti-loosening seat 301 automatically resets under the support of the spring to prevent the threaded rod 202 from loosening.

[0047] Operating steps of anti-loosening structure 3 and positioning mechanism 4: When anti-loosening operation is required on threaded rod 202, the operator first checks the position and status of anti-loosening seat 301. If anti-loosening seat 301 is locked, press the pressing plate on one side of anti-loosening seat 301 with your finger to overcome the elastic force of the support spring, causing anti-loosening seat 301 to move downwards until anti-loosening seat 301 separates and unlocks from locking block 303. At this time, the circumferential positioning of anti-loosening seat 301 by locking block 303 is released. If it is necessary to adjust the positioning inclined block 40 inside the stable housing 401... 2. To assist the rotation of the threaded rod 202, when the pressing plate of the anti-loosening seat 301 moves downward, it will squeeze the positioning wedge 402 to move to one side. If the pressing plate is pressed down, the positioning wedge 402 will return to one side under the action of the support spring. At this time, the positioning wedge 402 will lock the position of one side of the pressing plate, so as to facilitate the construction personnel to rotate the threaded rod 202. During the operation, pay attention to the function of the retaining spring on the outer side of the second positioning rod 403, which can prevent the positioning wedge 402 and the second positioning rod 403 from falling off.

[0048] The steps for setting up the top plate 104 and the formwork support structure 1 are as follows: as the height of the support rod 103 is adjusted, the top plate 104 at the top also rises or falls accordingly. The top plate 104 is adjusted to a position that is in close contact with the bottom of the concrete formwork. Since the top plate 104 is an inverted U-shaped structure, it can provide stable support for the right-angle position of the concrete formwork, ensuring that there is no gap or shaking between the top plate 104 and the formwork, so that the support structure 1 can effectively bear the load during the formwork and concrete pouring process.

[0049] If the construction personnel determine, based on the actual site conditions, that it is necessary to build a further supporting structure 1 on the basis of the existing supporting structure 1, then repeat the above steps to install the new supporting structure 1 in a suitable position and connect or work together with the existing supporting structure 1 to enhance the stability and load-bearing capacity of the overall support system.

[0050] After all support structures 1 are installed and adjusted, check the connections of each component again, including the tightness of the anchor bolts, the welding points between the stabilizing pipe 101 and the connecting plate 102, the fit between the threaded rod 202 and the positioning seat 201 in the adjusting structure 2, and the status of the anti-loosening structure 3 and the positioning mechanism 4. Use a wrench to fully tighten the anchor bolts to ensure that support structure 1 will not shift or loosen during concrete pouring.
