[0033] In this embodiment, in order to solve the problem that the fastener cannot change the angle with the object to be clamped in the related art, a multi-angle fastener is designed. First, a high-strength metal material is selected to manufacture the fastening body 12. The shape and size of the fastening body 12 should be designed according to the specific concrete pouring engineering requirements to ensure that it can smoothly penetrate the inner formwork and the outer formwork. A pair of ball head protrusions 1221 are formed at both ends of the fastening body 12. The surface of the ball head protrusion 1221 is smooth and has high dimensional accuracy to ensure that it can tightly fit with the spherical groove 1251 of the fastener 125 to form a stable spherical hinge pair. During concrete pouring construction, the inner formwork and the outer formwork are installed in place according to the design requirements, and then the fastening body 12 is inserted through the reserved holes of the inner formwork and the outer formwork. Then, a pair of fasteners 125 are installed at both ends of the fastening body 12, so that the spherical groove 1251 of the fastener 125 fits with the ball head protrusion 1221 of the fastening body 12 to form a spherical hinge pair. After adjusting the position and angle of the fastener 125, the position of the spherical groove 1251 and the ball head protrusion 1221 is fixed using a jack screw, so that a suitable clamping space is formed between the two pairs of fasteners 125. The inner main beam and the outer main beam are accurately placed in the clamping space, and the two fasteners 125 are tightly abutted with the outer main beam and the inner main beam respectively through fastening operation to provide sufficient clamping force.
[0034] The multi-angle clamping structure has the following advantages. First, the design of the spherical hinge pair allows the fastener 125 to rotate and adjust at multiple angles, greatly adapting to complex and variable concrete pouring construction environments. Whether in planar or curved pouring, the effectiveness of clamping can be ensured. Second, the inner formwork, the outer formwork, the inner main beam and the outer main beam can be firmly and uniformly clamped, effectively avoiding problems such as formwork displacement, deformation and concrete leakage during concrete pouring, thereby significantly improving the quality and precision of concrete pouring, ensuring that the poured concrete structure meets the design requirements and has good overall integrity and stability.

[0036] In this embodiment, when manufacturing each component of the fastening body 12, for the rod body 121, high-quality steel material is selected, and internal threads 1211 are accurately machined inside both ends of the rod body 121 by turning processing. The pitch, depth, and accuracy of the internal threads 1211 meet the design standards to ensure perfect fit with the external threads 1232 of the rotating rod 123. For the sleeve 122, steel material is also used for manufacturing, and the sleeve 122 is initially shaped by casting or forging process, and then machined to accurately set the ball head protrusions 1221 on both sides. The shape and size of the ball head protrusions 1221 are consistent with the design requirements to ensure good fit with the spherical groove 1251. The rotating rod 123 is also made of steel material, and one end is shaped into a holding part 1231 by machining for convenient manual operation by the construction personnel, and the other end is machined by turning to form the external threads 1232 matching the internal threads 1211 of the rod body 121. During assembly, the two sleeves 122 are oppositely installed at both ends of the rod body 121 to ensure that the sleeves 122 are firmly and accurately connected with the rod body 121. Then, the rotating rod 123 is oppositely and rotatably installed in the sleeves 122, and the external threads 1232 of the rotating rod 123 can smoothly fit with the internal threads 1211 of the rod body 121 without jamming and blocking during rotation and sliding.
[0037] The advantages of this structural design are as follows. First, the combination of the rod body 121, the sleeve 122, and the rotating rod 123 allows the construction personnel to quickly install and dismount the fastener 125 by manually operating the rotating rod 123 during construction, greatly improving the construction efficiency and shortening the construction period. Second, the threaded fit of the rotating rod 123 and the rod body 121 can provide strong and stable fastening force to ensure that the clamping structure does not loosen due to the pressure and vibration of the concrete during concrete pouring, thereby effectively ensuring the safety and reliability of the construction.
[0038] Further, the fastener 125 includes a mounting block 1252, the spherical groove 1251 is arranged on one side of the mounting block 1252, the first rotating block 1253 is used in pairs, the first rotating block 1253 used in pairs is rotatably arranged on the mounting block 1252, the second rotating block 1254 is used in pairs, the second rotating block 1254 used in pairs is rotatably arranged on the first rotating block 1253, and the abutting block 1255 is used in pairs, the abutting block 1255 used in pairs is rotatably arranged on the second rotating block 1254, and the abutting block 1255 is used for abutting with the outer main beam and the inner main beam.
[0039] In this embodiment, when manufacturing the various components of the fastener 125, first, the mounting block 1252 is manufactured using a high-strength metal material, and a spherical recess 1251 is precisely machined on one side thereof by machining, the size and shape of the spherical recess 1251 being perfectly matched with the ball head protrusion 1221 of the fastener body 12 to form a flexible ball hinge pair. For the first rotating block 1253, the second rotating block 1254, and the abutting block 1255, high-quality metal materials are also selected for manufacturing. Through precise machining and assembly processes, the pair of first rotating blocks 1253 are rotatably mounted on the mounting block 1252, so that the first rotating blocks 1253 can flexibly rotate on the mounting block 1252. Then, the pair of second rotating blocks 1254 are rotatably mounted on the first rotating blocks 1253, and the flexibility and stability of rotation are also ensured. Finally, the pair of abutting blocks 1255 are rotatably mounted on the second rotating blocks 1254, and the abutting blocks 1255 are ensured to be freely rotatable in various directions. In actual use, according to the shape and position of the inner and outer main beads, the angles of the various rotating blocks and the abutting blocks 1255 are adjusted, so that the abutting blocks 1255 can closely fit the inner and outer main beads to provide uniform and reliable clamping force.
[0040] The benefits of this complex rotating connection structure are as follows. First, through the rotating connection of multiple blocks, the abutting blocks 1255 can more flexibly adapt to the unevenness and shape changes of the inner and outer main bead surfaces, thereby achieving more clamping tightness and uniformity, improving the stability and reliability of clamping. Second, this structure can effectively disperse the stress generated during clamping, avoiding stress concentration at a certain point, thereby reducing damage to the main bead, prolonging the service life of the main bead, and reducing construction costs.
[0041] Further, the waterproof member 124 is provided, which is sleeved on both ends of the rod body 121, and the waterproof member 124 is conical, with the larger-diameter end of the waterproof member 124 being located in the same plane as the end face of the rod body 121.
[0042] In this embodiment, a rubber material with good waterproof performance and elasticity is selected to make the waterproof member 124. First, according to the size and shape of the two ends of the rod body 121, a corresponding mold is designed and manufactured. Then, the rubber material is placed in the mold, and the conical waterproof member 124 is made through a high-temperature vulcanization or injection molding process. The inner diameter of the waterproof member 124 is slightly smaller than the outer diameter of the rod body 121 to ensure that it can be tightly sleeved on both ends of the rod body 121. During installation, the waterproof member 124 is sleeved on both ends of the rod body 121, and is pressed tightly to ensure that the larger-diameter end of the waterproof member 124 is in the same plane as the end face of the rod body 121, forming a seamless connection and effectively blocking the intrusion of water.
[0043] The waterproof part 124 is designed to prevent water from penetrating into the fastener 125 during concrete pouring, thereby avoiding corrosion and damage of the fastener 125 due to long-term contact with water, greatly extending the service life of the fastener 125 and reducing maintenance costs.
[0044] Further, the rod body 121 has a first through slot 1212 in the middle.
[0045] In this embodiment, when manufacturing the rod body 121, according to the length, diameter and required bearing capacity of the rod body 121, a plurality of first through slots 1212 are uniformly machined along the axis of the rod body 121 in the middle by mechanical processing. The shape of the through slot can be rectangular, circular or other suitable shape, and the width and depth of the through slot are accurately controlled according to the specific design requirements. During processing, the edges of the through slot should be smooth without burrs and cracks to avoid stress concentration and fatigue cracks during use.
[0046] The design of such a through slot has the following benefits. First, by opening a through slot in the middle of the rod body 121, the weight of the rod body 121 is effectively reduced, making it easier for construction workers to operate and transport the rod body 121 during construction, reducing labor intensity and improving construction efficiency. Second, the arrangement of the through slot helps to save materials, reduce production costs, and reduce resource consumption, in line with the concept of sustainable development.
[0047] Further, the first through slots 1212 are uniformly distributed along the axis of the rod body 121.
[0048] In this embodiment, when designing and processing the first through slots 1212, the design scheme is strictly followed, and advanced numerical control machine tools or laser cutting equipment are used to uniformly distribute the through slots along the axis of the rod body 121. Through precise programming and control, the spacing between the through slots is ensured to be equal, and the angle deviation is controlled within a very small range. During processing, continuous detection and adjustment are carried out to ensure the processing precision and quality of the through slots.
[0049] The uniformly distributed through slots have the following benefits. First, when the rod body 121 is subjected to external forces, the uniformly distributed through slots can make the stress more evenly distributed on the rod body 121, avoiding local stress concentration, thereby significantly improving the structural strength and stability of the rod body 121 and extending its service life. Second, it ensures that the rod body 121 can maintain good working condition during concrete pouring without adversely affecting its overall mechanical properties and use effect, providing a strong guarantee for the smooth progress of construction.
