Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a structural column formwork reinforcement device. Background Technology

[0002] Structural columns, also known as reinforced concrete columns, are installed in the walls of multi-story brick-concrete structures to enhance the overall integrity and stability of the building. These columns connect to the ring beams on each floor, forming a spatial frame that resists bending and shear, effectively preventing building collapse. Structural columns are typically placed at the four corners of exterior walls, at the intersection of transverse and longitudinal walls in staggered floor areas, on both sides of large openings, and at the intersection of interior and exterior walls in large rooms. Furthermore, the requirements for structural columns vary depending on the number of stories and the seismic intensity; as the seismic intensity and number of stories increase, the cross-section and reinforcement grade of the structural columns at the four corners of the building need to be appropriately increased.

[0003] When using existing structural column formwork reinforcement devices, multiple formworks are stacked together according to the height of the structural column. However, the connection between the formworks is not tight, and the formworks lack sufficient strength and rigidity to resist the lateral pressure during concrete pouring. This causes the formworks to deform and bulge, resulting in deviations in the cross-sectional dimensions of the structural column, requiring additional repairs or even demolition and reconstruction. Utility Model Content

[0004] This utility model provides a structural column formwork reinforcement device to solve the technical problems of poor connection tightness and insufficient strength and rigidity when the formwork is stacked, which leads to easy deformation and bulging of concrete during pouring and deviation of the structural column section requiring rework.

[0005] This utility model solves the above-mentioned technical problems through the following technical solutions:

[0006] This utility model provides a structural column formwork reinforcement device, including a structural column and four mounting brackets. Two fixing blocks are fixedly installed on the mounting brackets. Each fixing block has a fixing groove inside. A connecting plate is slidably connected inside each fixing groove. A connecting rod and a positioning rod are fixedly installed at both ends of each connecting plate. One end of each connecting rod extends to the outer end of the mounting bracket and is fixedly installed with a pull plate. A pull ring is fixedly installed on one side of each pull plate. The mounting brackets have a first movable plate and a second movable plate inside. Each of the first movable plate and the second movable plate has multiple equally spaced positioning grooves. Both positioning rods can be inserted into the multiple positioning grooves.

[0007] In this technical solution, springs are fitted onto the outer surfaces of multiple connecting rods, and the two ends of the multiple springs are respectively fixedly connected to the fixing groove and the connecting plate.

[0008] In this technical solution, each of the multiple mounting brackets has two guide grooves, and a guide rod is fixedly installed inside each of the two guide grooves.

[0009] In this technical solution, two guide blocks are fixedly installed on both the first and second movable plates, and the two guide blocks are slidably connected to two guide rods respectively.

[0010] In this technical solution, a first connecting block and a second connecting block are respectively provided on the first movable plate and the second movable plate, and the position of the first connecting block is lower than the position of the second connecting block.

[0011] In this technical solution, through holes are provided on all four first connecting blocks and all four second connecting blocks.

[0012] In this technical solution, bolts are provided between the four mounting brackets, and multiple bolts can pass through the first connecting block and the second connecting block through through holes and are threaded with nuts.

[0013] In this technical solution, templates are provided on all four sides of the structural column.

[0014] In this technical solution, each of the four mounting brackets is rotatably connected to a support rod, and one end of each of the support rods is rotatably connected to a support plate.

[0015] In this technical solution, anti-slip pads are provided on multiple support plates.

[0016] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.

[0017] The positive and progressive effects of this utility model are as follows:

[0018] The aforementioned structural column formwork reinforcement device, by pulling the pull ring, releases the lock on the movable plate, allowing the first or second movable plate inside the mounting frame to slide along the guide rod via the guide block, thereby adjusting its position to accommodate different sized formwork and improving the device's versatility for structural columns of different sizes. After adjusting to the appropriate position, releasing the pull ring allows the positioning rod to insert into the corresponding positioning slot, fixing the position of the first or second movable plate. Multiple positioning slots further enhance the device's adaptability to different structural column sizes.

[0019] By aligning the first and second connecting blocks of adjacent mounting frames through the through holes, and tightening the nuts after the bolts pass through, the four mounting frames are connected into a rigid whole. The resulting square frame applies a uniform circumferential force to the template, effectively preventing the template from bulging and deforming due to lateral pressure during concrete pouring, ensuring the forming quality of the structural column and providing reliable reinforcement.

[0020] By rotating the support rod, the support plate with anti-slip pads is brought into contact with the ground; the support rod and the anti-slip pads form auxiliary support, increasing the friction with the ground, preventing the installation frame from tipping over, and improving construction safety; at the same time, it further enhances the stability of the overall device and ensures the safety of the construction process.

[0034] like Figure 1-5As shown, the structural column template reinforcement device includes a structural column 23 and four mounting brackets 1. Two fixing blocks 13 are fixedly installed on the mounting brackets 1. Each fixing block 13 has a fixing groove inside. Each fixing groove is slidably connected to a connecting plate 4. Each end of the connecting plate 4 is fixedly installed with a connecting rod 14 and a positioning rod 11. One end of each connecting rod 14 extends to the outer end of the mounting bracket 1 and is fixedly installed with a pull plate 15. Each pull plate 15 has a pull ring 3 fixedly installed on one side. The mounting bracket 1 has a first movable plate 8 and a second movable plate 24 inside. Each of the first movable plate 8 and the second movable plate 24 has multiple equally spaced positioning grooves 7. Each of the two positioning rods 11 can be inserted into the multiple positioning grooves 7.

[0035] In this technical solution, springs 2 are sleeved on the outer surfaces of multiple connecting rods 14, and the two ends of the multiple springs 2 are respectively fixedly connected to the fixing groove and the connecting plate 4.

[0036] In this technical solution, each of the multiple mounting brackets 1 has two guide grooves 9, and guide rods 10 are fixedly installed inside each of the two guide grooves 9.

[0037] In this technical solution, two guide blocks 22 are fixedly installed on the first movable plate 8 and the second movable plate 24. The two guide blocks 22 are slidably connected to the two guide rods 10 respectively. The cooperation between the guide rods 10 and the guide blocks 22 ensures smooth sliding and accurate positioning, and avoids the movable plates from shifting.

[0038] In this technical solution, the first movable plate 8 and the second movable plate 24 are respectively provided with a first connecting block 6 and a second connecting block 12, and the position of the first connecting block 6 is lower than the position of the second connecting block 12.

[0039] In this technical solution, through holes 5 are provided on all four first connecting blocks 6 and four second connecting blocks 12.

[0040] In this technical solution, bolts 18 are provided between the four mounting brackets 1. Each bolt 18 can pass through the first connecting block 6 and the second connecting block 12 through the through hole 5 and be threaded with a locking nut 17.

[0041] In this technical solution, templates 19 are provided on all four sides of the structural column 23.

[0042] In this technical solution, each of the four mounting brackets 1 is rotatably connected to a support rod 16, and one end of each of the support rods 16 is rotatably connected to a support plate 20.

[0043] In this technical solution, anti-slip pads 21 are provided on each of the multiple support plates 20.

[0044] In use, the four mounting brackets 1 correspond to the four sides of the structural column 23, with the inner sides fitting against the template 19 to form a preliminary square frame. When it is necessary to adjust the position of the first movable plate 8 or the second movable plate 24 according to the size of the structural column 23, the pull ring 3 is pulled, which drives the connecting plate 4 to slide in the fixed groove through the connecting rod 14. At the same time, the connecting plate 4 compresses the spring 2, causing the positioning rod 11 to be pulled out from the positioning groove 7, releasing the lock on the first movable plate 8 or the second movable plate 24. This allows the first movable plate 8 or the second movable plate 24 inside the mounting bracket 1 to slide along the guide rod 10 through the guide block 22, realizing position adjustment to adapt to templates 19 of different sizes, improving the versatility of the device for structural columns 23 of different sizes. After adjusting to the appropriate position, the pull ring 3 is released, the spring 2 returns to its original position, and pushes the connecting plate 4, causing the positioning rod 11 to insert into the corresponding positioning groove. The first movable plate 8 or the second movable plate 24 is fixed in position; multiple positioning slots enhance the adaptability of the device to different structural column 23 sizes; the first connecting block 6 and the second connecting block 12 of adjacent mounting brackets 1 are aligned through the through hole 5, so that the bolt 18 passes through and the locking nut 17 is tightened, connecting the four mounting brackets 1 into a rigid whole. The square frame formed applies a uniform circumferential force to the template 19, effectively preventing the template 19 from bulging and deforming due to lateral pressure during concrete pouring, ensuring the forming quality of the structural column 23 and reliable reinforcement; rotating the support rod 16 makes the support plate 20 with anti-slip pad 21 contact the ground; the support rod 16 and the anti-slip pad 21 form an auxiliary support, increasing the friction with the ground, preventing the mounting bracket 1 from tipping over, and improving construction safety; at the same time, it further enhances the overall stability of the device and ensures the safety of the construction process.

[0045] The advantages of this application are:

[0046] 1. By pulling the pull ring 3, the locking of the movable plate is released, allowing the first movable plate 8 or the second movable plate 24 inside the mounting frame 1 to slide along the guide rod 10 via the guide block 22, thereby adjusting its position to adapt to different sized templates 19 and improving the versatility of the device for structural columns 23 of different sizes. After adjusting to the appropriate position, the pull ring 3 is released, allowing the positioning rod 11 to be inserted into the corresponding positioning groove 7 to fix the position of the first movable plate 8 or the second movable plate 24; and the multiple positioning grooves 7 enhance the adaptability of the device to different sizes of structural columns 23.

[0047] 2. By aligning the first connecting block 6 and the second connecting block 12 of the adjacent mounting bracket 1 through the through hole 5, and tightening the locking nut 17 after the bolt 18 passes through, the four mounting brackets 1 are connected into a rigid whole. The square frame formed applies a uniform circumferential force to the template 19, which effectively prevents the template 19 from bulging and deforming due to lateral pressure during concrete pouring, ensuring the forming quality of the structural column 23 and making the reinforcement reliable.

[0048] 3. By rotating the support rod 16, the support plate 20 with the anti-slip pad 21 is brought into contact with the ground; the support rod 16 and the anti-slip pad 21 form an auxiliary support, increasing the friction with the ground, preventing the installation frame 1 from tipping over, and improving construction safety; at the same time, it further enhances the overall stability of the device and ensures the safety of the construction process.
