Description

Technical Field

[0001] This invention relates to the technical field of clamp structures, and more specifically, to a clamp structure and a support structure. Background Technology

[0002] Clamps are common fasteners used in engineering projects. They are often used to connect to columns in construction sites.

[0003] Existing clamps consist of two semi-circular steel plates, with the arc of the plates abutting against the column, and the two plates are connected by bolts. However, the inner diameter of this type of clamp cannot be changed according to usage requirements, leading to the development of clamps with variable inner diameters.

[0004] As described in Chinese Patent CN201810108240.1, a lifting clamp device with an adjustable diameter includes: a clamp half-ring A, a clamp half-ring B, a lifting clamp A, a lifting clamp B, a ball bearing slide mechanism, and a ratchet stop mechanism; the two clamp half-rings are connected by hinges, and the diameter of the entire lifting clamp device is changed by the cooperation of the ratchet mechanism and the ratchet stop mechanism to adapt to various specifications of lifting parts; the lifting clamp device is locked to the lifting part by the lifting clamp, and after the device diameter is adjusted, the position of the lifting clamp is adjusted by the ball bearing slide mechanism; in use, simply fix the lifting clamp A on the clamp half-ring A to the lifting part, then push the ratchet end of the clamp half-ring B until the diameter is adapted to the lifting part, and finally lock the lifting clamp B to the lifting part; the locking button in the ratchet stop mechanism can release the ratchet on the clamp half-ring B when pressed. The advantages of this patent are that it can adapt to various specifications of lifting parts, and the entire device is safe, reliable, and easy to operate.

[0005] However, in implementing the above technical solution, it was found that at least the following problems need to be improved: The existing variable inner diameter clamp achieves the change of the clamp's inner diameter by rotating or moving the clamp's semi-rings relative to each other. After adjusting the inner diameter, the shape and curvature of the clamp's semi-rings cannot change, meaning the clamp structure's accommodating space is not circular (generally elliptical), but the column's cross-section is circular. This results in the clamp and column essentially having only two points of contact, and the insufficient number of contact points leads to low reliability of the clamp-column fit. Summary of the Invention

[0006] The primary objective of this invention is to provide a clamping structure in which the insert plate and the access plate can rotate relative to each other to fit as closely as possible to the support column, thereby increasing the contact points between the clamping structure and the support column and further improving the reliability of the connection between the clamping structure and the support column.

[0007] The second objective of this invention is to provide a support structure in which a Bailey bridge and a disc buckle frame are installed in the clamp structure. This embodiment facilitates installation and disassembly during construction and improves construction efficiency.

[0008] The embodiments of the present invention are implemented as follows: In a first aspect, embodiments of this application provide a clamp structure, including multiple insert plates, with an access plate provided between any adjacent insert plates. The insert plates and access plates are connected end to end to form a ring structure, and the insert plates and access plates are rotatably connected and detachably connected.

[0009] In some embodiments of the present invention, the insert plate or access plate is provided with a fine-tuning tensioning element.

[0010] In some embodiments of the present invention, the fine-tuning tensioning element is a tensioning screw, which is rotatably connected to the insertion plate or the access plate.

[0013] In some embodiments of the present invention, the access plate includes a support housing, the support housing is provided with a movable through groove along the length direction of the support housing, the movable through groove is provided with a fine-tuning column that can move along the movable through groove, the fine-tuning column is symmetrically arranged on the left and right sides of the movable through groove, a rotating through hole is provided in the fine-tuning column, and the access plate also includes a fine-tuning component for making the fine-tuning column move closer to each other or further away from each other.

[0014] In some embodiments of the present invention, the fine-tuning component includes a fine-tuning screw parallel to the length direction of the movable channel, the fine-tuning screw being rotatably connected to the support housing, the fine-tuning screw being threadedly connected to the fine-tuning column, the thread direction of the fine-tuning screw being connected to different fine-tuning columns being different, and the fine-tuning component also includes horizontal teeth meshing with the fine-tuning columns, the horizontal teeth being arranged along the length direction of the movable channel.

[0015] In some embodiments of the present invention, a safety spring is provided between the fine-tuning columns to abut against the fine-tuning columns on both sides.

[0016] Secondly, embodiments of this application provide a support structure, including the above-mentioned clamp structure, with a Bailey bridge bolted to the insert plate, and a disc buckle frame provided on the upper side of the Bailey bridge.

[0017] In some embodiments of the present invention, a distribution beam is provided between the Bailey bridge and the disc buckle frame, the Bailey bridge and the distribution beam are fixedly connected, and the distribution beam and the disc buckle frame are fixedly connected.

[0018] Compared with the prior art, the embodiments of the present invention have at least the following advantages or beneficial effects: Regarding the first aspect, the insert plate and the access plate can rotate relative to each other to fit as closely as possible to the support column, increasing the contact points between the clamp structure and the support column, and further improving the reliability of the connection between the clamp structure and the support column. During use, the number of insert plates and access plates can be selected according to the diameter of the support column, thereby adjusting the diameter of this clamp structure. This eliminates the need to manufacture clamp structures separately for support columns of different diameters, improving the adaptability of the clamp structure.

Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Example 1 like Figure 2-7 As shown, this embodiment provides a clamp structure, including multiple insert plates 101. An access plate 102 is provided between any adjacent insert plates 101. The insert plates 101 and the access plates 102 are connected end to end to form a ring structure. The insert plates 101 and the access plates 102 are rotatably connected and can be detachably connected.

[0024] In this embodiment, the adjacent interlocking plates 101 and access plates 102 are connected end to end to form a ring structure, and the support column 2 is located at the center of the ring structure.

[0025] Both the insertion plate 101 and the access plate 102 are rectangular or arc-shaped clamping plates 1. Adjacent insertion plates 101 and access plates 102 are rotatably connected. Depending on the shape and size of the support column 2, the insertion plates 101 and access plates 102 can rotate relative to each other to fit as close as possible to the support column 2, increasing the contact points between the clamping structure and the support column 2, and further improving the reliability of the connection between the clamping structure and the support column 2.

[0026] Compared to the existing semi-circular clamp plate 1 (such as...) Figure 1 As shown in the figure, this embodiment uses multiple cuboid or arc-shaped clamping plates 1. After adjusting the inner diameter, the inserting plate 101 and the access plate 102 can rotate relative to each other and adjust the shape of the clamping structure, which increases the contact point and contact area between the clamping structure and the support column 2.

[0027] The insertion plate 101 and the access plate 102 are detachably connected. When in use, the number of insertion plates 101 and access plates 102 can be selected according to the diameter of the support column 2, thereby adjusting the diameter of this clamp structure. There is no need to produce clamp structures separately for support columns 2 with different diameters, which improves the adaptability of the clamp structure.

[0028] In specific connection, both the left and right sides of the insertion plate 101 and the access plate 102 can be provided with rotating holes to accommodate the rotating shaft. During connection, the rotating hole on the left side of the insertion plate 101 coincides with the rotating hole on the access plate 102 located on the left side of the insertion plate 101, and the rotating shaft passes through the rotating holes of the insertion plate 101 and the access plate 102 to realize the connection between the insertion plate 101 and the access plate 102.

[0029] Specifically, in order to increase the contact points and contact area between the clamp structure and the support column 2 during use, the lengths of the insert plate 101 and the access plate 102 can be shortened, so that the clamp structure with the same perimeter has more insert plates 101 and access plates 102, thereby increasing the contact points and contact area between the clamp structure and the support column 2.

[0030] Specifically, in use, the interleaving plate 101 is often located on the upper side of the access plate 102 to prevent interference between the interleaving plate 101 and the access plate 102.

[0031] Specifically, at the time of manufacture, the insert plate 101 and the access plate 102 can be in bulk. When a clamp is required, the number of insert plates 101 and access plates 102 can be selected according to the diameter of the support column 2, thereby adjusting the diameter of the clamp structure.

[0032] Specifically, the insert plate 101 and the access plate 102 can be connected end to end in a ring structure at the factory. When in use, first remove one section of insert plate 101 or access plate 102 to change the ring structure of the clamp structure into a chain structure. After the chain clamp structure surrounds the support column 2, the remaining insert plates 101 and access plates 102 at both ends are interlocked and connected to each other, so that the clamp structure is clamped to the support column 2.

[0033] In some embodiments of this example, the insertion plate 101 or the access plate 102 is provided with a fine-tuning tensioning element.

[0034] In the above embodiments, during installation or actual use, there may be a gap between the clamp structure and the support column 2. At this time, the clamp structure support column 2 is made to abut against the clamp structure by using the fine-tuning tensioner to ensure the safety of the clamp structure.

[0035] The fine-tuning tensioner can be an airbag installed between the insert plate 101 and the support column 2 or an airbag installed between the access plate 102 and the support column 2. When there is a gap between the insert plate 101 (or access plate 102) and the support column 2, air can be injected into the airbag to fill the gap between the insert plate 101 (or access plate 102) and the support column 2, thereby causing the clamp structure support column 2 to abut.

[0036] In some embodiments of this example, the fine-tuning tensioning element is a tensioning screw 3, which is rotatably connected to the insertion plate 101 or the access plate 102.

[0037] In the above embodiment, the tensioning screw 3 is provided with an external thread on its outer periphery, and the insertion plate 101 or the access plate 102 is provided with a threaded hole leading to the support column 2. The tensioning screw 3 is installed in the threaded hole, and the tensioning screw 3 is threadedly connected to the insertion plate 101 or the access plate 102 through the threaded hole.

[0038] When there is a gap between the clamp structure and the support column 2, the tensioning screw 3 can be rotated so that it extends between the insert plate 101 or the access plate 102 and the support column 2, and the tensioning screw 3 abuts against the support column 2. If the tensioning screw 3 is rotated further, it will continue to abut against the support column 2, and eventually other insert plates 101 or access plates 102 that are far away from the tensioning screw 3 will abut against the support column 2, ensuring the reliability of the connection between the clamp structure and the support column 2.

[0039] In some embodiments of this example, the bottom of the insertion plate 101 is provided with a rotating shaft 111, and the access plate 102 is provided with a rotating through hole 120 for accommodating the rotating shaft 111, and the rotating shaft 111 is rotatably connected to the rotating through hole 120.

[0040] In the above embodiment, during the installation process, the insertion plate 101 and the access plate 102 are rotatably connected through the rotating shaft 111 and the rotating through hole 120.

[0041] In some embodiments of this example, the rotating shaft 111 passes through the rotating through hole 120, and a fixing nut 112 is provided at the point where the rotating shaft 111 extends out of the rotating through hole 120. The fixing nut 112 is threadedly connected to the rotating shaft 111.

[0042] In the above embodiment, after the rotating shaft 111 passes through the rotating through hole 120, a fixing nut 112 can be screwed in to prevent the rotating shaft 111 from falling off the rotating through hole 120 during use, thus ensuring the reliability of the clamp structure.

[0043] In some embodiments of this example, the access plate 102 includes a support housing 121. The support housing 121 has a movable through groove 122 along its length. The movable through groove 122 has a fine-tuning column 124 that can move along the movable through groove 122. The fine-tuning column 124 is symmetrically arranged on the left and right sides of the movable through groove 122. A rotating through hole 120 is provided in the fine-tuning column 124. The access plate 102 also includes a fine-tuning component for making the fine-tuning columns 124 move closer or further apart from each other.

[0044] In the above embodiments, during the production process, the movable channel 122 can be formed by shelling or cutting the support housing 121, and the movable channel 122 provides space for the installation and movement of the fine-tuning column 124.

[0045] Each of the fine-tuning columns 124 is provided with a rotating through hole 120. There are two fine-tuning columns 124, and they are respectively located on the left and right sides of the movable through slot 122, so as to facilitate the connection between the rotating shaft 111 of the through plate 101 (on both sides of the access plate 102) and the rotating through hole 120 of the fine-tuning column 124 on both sides of the access plate 102.

[0046] Meanwhile, the access plate 102 is also equipped with a fine-tuning component for adjusting the relative positions between the fine-tuning columns 124, providing users with another way to adjust the clamp structure. This avoids the problem of difficulty in installing the last insert plate 101 or access plate 102 of the clamp structure when the inner diameter of the clamp may be slightly shorter than the circumference of the support column 2. In this case, the position of the fine-tuning column 124 can be adjusted by the fine-tuning component, thus achieving a smooth installation of the clamp structure.

[0047] In some embodiments of this example, the fine-tuning component includes a fine-tuning screw 123 parallel to the length direction of the movable through slot 122. The fine-tuning screw 123 is rotatably connected to the support housing 121. The fine-tuning screw 123 is threadedly connected to the fine-tuning column 124. The thread direction of the fine-tuning screw 123 connected to different fine-tuning columns 124 is different. The fine-tuning component also includes horizontal teeth 126 that mesh with the fine-tuning columns 124. The horizontal teeth 126 are arranged along the length direction of the movable through slot 122.

[0048] In the above embodiment, the fine-tuning screw 123 passes through the access plate 102 along the length direction of the movable through slot 122, and the access plate 102 is rotatably connected to the support housing 121.

[0049] The fine-tuning cylinder 124 is threadedly connected to the fine-tuning screw 123. The two fine-tuning cylinders 124 are located on the left and right sides of the fine-tuning screw 123, respectively, facilitating engagement between the fine-tuning cylinders 124 and the fine-tuning screw 123. Simultaneously, the threads on the left and right sides of the fine-tuning screw 123 rotate in opposite directions, causing the fine-tuning cylinders 124 on both sides to rotate in different directions when the fine-tuning screw 123 rotates. At this time, the fine-tuning cylinders 124 also engage with the horizontal teeth 126, allowing the fine-tuning cylinders 124 to rotate freely. The movement is converted into movement along the direction of the horizontal teeth 126 (in this embodiment, the horizontal teeth 126 are arranged along the length of the moving through groove 122, so that the fine-tuning column 124 moves within the moving through groove 122), thereby causing the fine-tuning columns 124 to move closer to or further away from each other when the fine-tuning screw 123 rotates (because the threads of the fine-tuning columns 124 have different directions of rotation, the movement directions of the two fine-tuning columns 124 are always opposite), and finally the position of the fine-tuning column 124 is adjusted.

[0050] At the same time, the movement of the two fine-tuning columns 124 occurs simultaneously and at the same distance, ensuring that the force on the fine-tuning columns 124 is more uniform and ensuring the reliability of the access board 102 for long-term use.

[0051] In some embodiments of this example, a safety spring 127 is provided between the fine-tuning columns 124 to abut against the fine-tuning columns 124 on both sides.

[0052] In the above embodiment, one end of the safety spring 127 is fixed to the fine-tuning column 124 on the left side, and the other end of the safety spring 127 is fixed to the fine-tuning column 124 on the right side. At the same time, the safety spring 127 is always kept in a compressed or stretched state, so that the safety spring 127 always applies a pushing or pulling force to the fine-tuning column 124, thereby preventing the fine-tuning column 124 from moving due to vibration and ensuring the safety of the access plate 102.

[0053] In some embodiments of this example, the fine-tuning screw 123 is provided with a screw baffle 125, which is located on the outside of the support housing 121 to prevent the fine-tuning screw 123 from falling off the support housing 121 during use.

[0054] In some embodiments of this example, the end face of the fine-tuning screw 123 is provided with a screwdriver hole 128. The screwdriver hole 128 can be a hexagonal bolt hole, which can be adapted to common electric screwdrivers. This makes it convenient for the operator to use an electric screwdriver to drive the fine-tuning screw 123 to rotate during use, thereby improving the adjustment efficiency of the access plate 102.

[0055] Example 2 like Figure 8 As shown, this embodiment provides a support structure, including the above-mentioned clamp structure, with the Bailey bridge 4 bolted to the insert plate 101, and a disc buckle frame 5 provided on the upper side of the Bailey bridge 4.

[0056] In this embodiment, the Bailey bridge 4 and the disc-lock frame 5 (also called the socket-type disc-lock steel pipe support frame) are installed on the interlocking plate 101 (connected by bolts) in the clamping structure. Compared with the construction process of the traditional cantilever support frame, the assembly characteristics of the Bailey beam give it advantages in transportation, hoisting, disassembly and layout flexibility. At the same time, the Bailey bridge 4 and the disc-lock frame 5 can be connected by bolts during installation, which facilitates installation and disassembly during construction and improves construction efficiency.

[0057] Meanwhile, the Bailey bridge 4 has inclined support members inside. Compared with the support structure with only horizontal support members, the Bailey bridge 4 has better strength. Under the same stress conditions, the use of Bailey bridge 4 can reduce the amount of steel used.

[0058] The construction process of the cantilever support frame can be as follows: the I-beams are anchored to the clamp structure or other building structure, the I-beams are used as the support platform, and a load-bearing frame is erected on it. The I-beams are connected to each other and to the load-bearing frame by welding, which results in low installation efficiency and troublesome disassembly.

[0059] In some embodiments of this example, a distribution beam 6 is provided between the Bailey bridge 4 and the disc buckle frame 5, the Bailey bridge 4 and the distribution beam 6 are fixedly connected, and the distribution beam 6 and the disc buckle frame 5 are fixedly connected.

[0060] In the above embodiment, the surface of the main body of the Bailey bridge 4 has no supporting material, which makes the installation of the Bailey bridge 4 and the disc buckle frame 5 more difficult. Installing the distribution beam 6 between the Bailey bridge 4 and the disc buckle frame 5 can increase the installation area between the Bailey bridge 4 and the disc buckle frame 5 and improve the convenience of installation.

[0061] Among them, the distribution beam 6 can be an I-beam.

[0062] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
