[0002] Technical drawbacks of traditional clamp components:

[0003] 1. The monolithic structure leads to high transportation costs.

[0004] Traditional clamps are mostly welded, one-piece steel rings with a fixed size that cannot be disassembled. They occupy a lot of space during transportation, have a low loading capacity per vehicle (for example, a 40-foot container can only carry about 200 sets), and logistics costs account for as much as 15% to 20% of the total cost.

[0005] 2. Low installation efficiency

[0006] Multiple people are required to complete the clamping operation. Installing a single clamp takes an average of 5 to 8 minutes. The bolt hole alignment is difficult and often requires the use of tools such as pry bars to forcibly correct it, which can damage the threads.

[0007] Therefore, it is necessary to design a foldable modular square column clamp. The clamp can be folded to facilitate transportation. Moreover, the device only requires the insertion of a pin and the use of a spring clip to complete the clamping process, which improves the installation efficiency compared to traditional clamps.

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0029] Example 1:

[0030] Key reference Figure 1-5 The device mainly includes a first aluminum alloy sheet 1, a second aluminum alloy sheet 4, and a rotating column 3.

[0031] This device comprises two sets of semi-clamping components, each consisting of a first aluminum alloy plate 1, a rotating column 3, and a second aluminum alloy plate 4. For ease of distinction, the two sets of semi-clamping components are referred to as the first semi-clamping component and the second semi-clamping component, respectively.

[0032] The first aluminum alloy sheet 1 has a first groove 2 in the middle of its top and bottom, so that the first aluminum alloy sheet 1 is I-shaped, which is used to reduce the weight of the first aluminum alloy sheet 1.

[0033] The second aluminum alloy sheet 4 has a second groove 5 in the middle of its top and bottom, which makes the second aluminum alloy sheet 4 I-shaped and reduces the weight of the second aluminum alloy sheet 4.

[0034] Both the first aluminum alloy sheet 1 and the second aluminum alloy sheet 4 have a limiting rotation groove 11 at their ends. The two limiting rotation grooves 11 are connected by a rotating column 3 for limiting rotation. Both the first aluminum alloy sheet 1 and the second aluminum alloy sheet 4 have multiple pin holes 6 on the side away from the rotating column 3. The multiple pin holes 6 on the second aluminum alloy sheet 4 are arranged parallel to the second aluminum alloy sheet 4, and the multiple pin holes 6 on the first aluminum alloy sheet 1 are arranged parallel to the first aluminum alloy sheet 1.

[0035] The pin 8 passes through both the pin hole 6 on the second aluminum alloy plate 4 of the first set of semi-clamping parts and the pin hole 6 on the first aluminum alloy plate 1 of the second set of semi-clamping parts. An annular groove 9 is formed on the outer wall of the pin 8, and a spring retainer 10 is installed on the outer wall of the annular groove 9. A baffle 7 is fixedly connected to one end of the pin 8. The diameter of the pin 8 is slightly smaller than the diameter of the pin hole 6. The first aluminum alloy plate 1 and the second aluminum alloy plate 4 are positioned between the baffle 7 and the spring retainer 10.

[0036] The pin 8 passes through both the pin hole 6 on the second aluminum alloy plate 4 of the second set of semi-clamping parts and the pin hole 6 on the first aluminum alloy plate 1 of the first set of semi-clamping parts. An annular groove 9 is formed on the outer wall of the pin 8, and a spring retainer 10 is installed on the outer wall of the annular groove 9. A baffle 7 is fixedly connected to one end of the pin 8. The diameter of the pin 8 is slightly smaller than the diameter of the pin hole 6. The first aluminum alloy plate 1 and the second aluminum alloy plate 4 are positioned between the baffle 7 and the spring retainer 10.

[0037] Example 2: Based on Example 1, a technical means was added to prevent excessive friction between the first aluminum alloy sheet 1 and the second aluminum alloy sheet 4.

[0038] This embodiment mainly includes a polytetrafluoroethylene gasket 12.

[0039] The outer wall of the rotating column 3 is fitted with a polytetrafluoroethylene gasket 12, which is placed between the first aluminum alloy sheet 1 and the second aluminum alloy sheet 4.

[0040] The other features of Example 2 are the same as those of Example 1.

[0041] 1. This device is a split-type rotating structure.

[0042] It consists of two pairs of mirror-symmetrical clamp assembly units, each unit containing two irregularly shaped aluminum alloy sheets (6061-T6, yield strength ≥275MPa) with hinged ends.

[0043] Component dimensions: The irregular aluminum alloy sheet of a single clamp unit is 600-1200mm long (can cover 400-1000mm square columns), 120mm wide, and 2.5mm thick; the overlap width at the hinge of the two aluminum alloy sheets is 30mm to ensure rotational stability.

[0044] Hinged structure: A 1mm thick polytetrafluoroethylene gasket is built into the hinge to reduce rotational wear and achieve smooth rotation from 0 to 180°.

[0045] 2. Topology-optimized profile design

[0046] Hollow Structure: The aluminum alloy sheet adopts an I-shaped hollow weight-reduction structure (cross-section dimensions: 120mm wide × 25mm high, hollow part dimensions: 80mm × 15mm), and the weight per linear meter is reduced by 43% compared to steel parts when the wall thickness is 2.5mm;

[0047] Reinforcing rib parameters: The edge reinforcing ribs are a continuous triangular array (15mm base, 10mm height, 50mm spacing), integrally extruded with the aluminum alloy sheet, increasing the local compressive strength to 320MPa (60% higher than ordinary flat plate structure) and the local bending stiffness to 21000N·mm² / mm.

[0048] 3. Dynamic adjustment system

[0049] Pin hole design: Pin holes with a tolerance of Φ12H7 (hole depth 20mm) are made every 50mm along the length of the aluminum alloy sheet. The edge of the hole is marked with a scale of 0-500mm (laser engraving, accuracy ±1mm) for easy positioning.

[0050] Pin structure: The pin is made of 45# steel (Φ12g6 tolerance, length 50mm), with an annular groove at the head and a matching spring retainer (diameter 8mm). After insertion, the retainer is embedded in the groove to prevent it from falling out. The insertion and withdrawal force is ≤50N (single person operation is possible).

[0051] Compatibility range: By combining clamp units of different lengths (600mm / 800mm / 1000mm) and adjusting the pin holes, it can cover square columns from 400mm×400mm to 1000mm×1000mm (13 adjustment levels in 50mm increments).

[0052] 4. Surface treatment and durability (addressing maintenance / lifespan issues)

[0053] Micro-arc oxidation process: using aluminosilicate electrolyte, the process is carried out at a voltage of 300-500V for 15 minutes to form a 30μm thick oxide film (film hardness ≥300HV), with an adhesion level of Grade 1 (no peeling) in GB / T 9286-1998.

[0054] Corrosion resistance verification: After 1000 hours of neutral salt spray test (5% NaCl solution, 35℃) according to GB / T 10125-2021, there was no rust or coating peeling (see attached screenshot of test report); all metal connectors (bolts, pins) are made of 304 stainless steel to avoid electrochemical corrosion.

[0055] (3) Construction process

[0056] Step 1: Conduct a thorough briefing before construction, clearly explaining the assembly points of the clamp components to the construction personnel;

[0057] Step 2: Check that all parts of the clamp are intact. Do not use any damaged or incomplete components. After the inspection is completed, construction can begin.

[0058] Step 3: According to the requirements of the relevant construction plan for the formwork, put the two clamp units together diagonally opposite each other, and fasten the corresponding pin holes with pins according to the size of the square column.

[0059] Step 4: When dismantling, remove the pin and stack the clamp units together for storage.

[0060] IV. Technical Effects

[0061] Structural innovation: The traditional one-piece steel ring is disassembled into rotatable and foldable aluminum alloy modular units. The combination of "hinged joints and pins" enables quick assembly and disassembly and size adjustment, solving the problems of large space occupation and poor adaptability of traditional clamps during transportation.

[0062] Material and process innovation: 6061-T6 aluminum alloy (yield strength 275MPa, higher than the traditional Q235 steel 235MPa) is selected and combined with topology optimization design. While reducing the wall thickness by 20% (2.5mm vs 3mm), the weight is reduced by 43% (3.2kg vs 8kg). At the same time, the service life is extended from 3 years to 10 years through micro-arc oxidation coating.

[0063] Efficiency Improvement: The installation time is reduced from 8 minutes to 2 minutes by adjusting the 50mm level pin hole (compared to the traditional 150mm) and the quick-locking structure can be operated by a single person, and no pry bar is required for correction (the bolt hole position is pre-aligned by the elongated hole + positioning pin).

[0064] Folded volume: 1 / 4 of the unfolded volume (an 800mm long piece can be folded down to 200mm).

[0065] Single unit load capacity: ≥8kN (meets the requirements of GB50204-2015 for concrete lateral pressure).

[0066] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
