Description

Technical Field

[0001] A positioning and connection device for oblique steel structures is disclosed, which is used for positioning oblique steel structures and belongs to the technical field of positioning and connection devices. Background Technology

[0002] Skewed steel structures are an important form of steel structure system, especially widely used in high-rise buildings and large-span structures. Skewed grid structures are a typical example of skewed steel structures, achieving efficient stress distribution in spatial structures through the arrangement of skewed members.

[0003] In high-rise steel structures, oblique grid structures effectively resist vertical and horizontal loads, transferring the internal forces of corner columns to the center of the facade and reducing shear hysteresis. Simultaneously, the outer ring beams effectively constrain the oblique columns to work together, giving the entire structure strong spatial coordination and torsional stiffness. The main advantage of oblique grid structures lies in their ability to distribute forces in various directions, thereby improving the overall load-bearing capacity and stability of the structure.

[0004] The inclined columns and supports in a spiral staircase are key components of its unique structure and support system. These inclined members not only provide support for the staircase but also affect the stability and load-bearing capacity of the entire structure.

[0005] Inclined columns are typically located at the center or key support points of a spiral staircase. They form an angle with the horizontal plane and serve to support and transfer loads. Through precise calculations and design, these inclined columns ensure that they can withstand the weight from the stair steps and users, and effectively transfer it to the ground or other foundation structures.

[0006] Diagonal supports are structural members that connect inclined columns to stair steps or platforms. They help distribute and transfer loads, ensuring the stability of the staircase under external forces. The design and installation location of diagonal supports are also carefully considered to maximize the overall stiffness and stability of the structure.

[0007] However, in the existing technology, the inclined supports are installed on the inclined columns by hoisting and at the corresponding inclination angle, which has the following technical problems:

[0008] 1. During the installation of inclined supports, due to factors such as wind force, the precision limitations of the hoisting equipment, and the skill level of the operators, it is difficult to accurately control the installation position and tilt angle of the inclined supports. This can easily lead to deviations in the connection between the inclined supports and the inclined columns, thereby affecting the stability and safety of the entire structure.

[0009] 2. Low docking efficiency, which easily leads to low construction efficiency. Utility Model Content

[0010] The purpose of this utility model is to provide a positioning and connection device for skewed steel structures, which solves the problem that during the hoisting process of skewed supports, due to factors such as wind force, the precision limitations of hoisting equipment, and the skill level of operators, it is difficult to accurately control the installation position and tilt angle of the skewed supports, which can easily lead to deviations in the connection between the skewed supports and the skewed columns, thereby affecting the stability and safety of the entire structure.

[0011] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0012] A positioning and connection device for skewed steel structures includes a fixing structure fixed to the skewed column, and a support structure installed on the fixing structure to limit the skewed support and connect it to the skewed column.

[0013] The supporting structure includes at least two limiting members. Each limiting member includes a grooved component with a sliding groove fixedly mounted on the fixed structure, a limiting rod that rotates in coordination with the fixed structure, a rotating component that passes through the groove and is connected to the limiting rod, a limiting groove provided on the opposite side of the grooved component along its length, two sides of the rotating component passing through the groove, and a bolt and a nut that cooperate with the bolt that are slidably mounted in the limiting groove.

[0014] Furthermore, a connecting block is provided on the fixed structure, and a rotating shaft is rotatably provided on the connecting block, with a limiting rod connected to the rotating shaft.

[0015] Furthermore, the rotating component includes a vertical rod passing through the slide groove and a multi-segment connecting rod connected to the vertical rod and the limiting rod.

[0016] Furthermore, the fixing structure includes a first connector and a second connector that cooperate with the inclined column, and the two ends of the first connector and the second connector are fixed to the inclined column by bolts and nuts.

[0017] A support structure is provided on the first connector and / or the second connector.

[0018] Furthermore, the first connector and the second connector respectively include an upper clamping piece and a lower clamping piece, a connecting structure connecting the two ends of the upper clamping piece and the lower clamping piece, a limiting piece and a connecting block disposed on the connecting structure, and a fixing block connected to the connecting structure. The fixing block is provided with a mounting hole, and an oblique support docking cavity is formed between the two connecting structures on the first connector and the second connector.

[0019] Furthermore, the connecting structure includes an upper reinforcing bar connected to the upper clamping plate, a lower reinforcing bar connected to the lower clamping plate, an mounting plate connected to the upper and lower reinforcing bars, and a limiting member and a connecting block disposed on the mounting plate; or

[0020] The connection structure includes a connecting piece connected to the upper clamping piece and the lower clamping piece, and a limiting member and a connecting block are disposed on the connecting piece.

[0021] Furthermore, the limiting rod is a cylindrical rod.

[0022] Compared with the prior art, the advantages of this utility model are:

[0023] I. This utility model achieves a stable installation of the fixed structure on the inclined column. When the bolts are loosened, the limiting rod in the support structure rotates in conjunction with the fixed structure, while the rotating part rotates in the sliding groove. When the limiting rod rotates to the required angle, the two bolts in the limiting groove move and are fixed by the nut to fix and limit the rotating part and the limiting rod, thereby fixing the angle of the limiting part. When hoisting the inclined support, the inclined support can be placed on the limiting rod, which facilitates the angle limitation of the inclined support by the limiting rod, thereby improving the installation accuracy between the inclined support and the inclined column and avoiding the deviation that may occur in the traditional hoisting method. As a result, after installation, the stability and safety of the entire structure are improved, and the docking efficiency is also improved, which greatly shortens the construction cycle.

[0024] II. This utility model allows the limiting rod to rotate around the rotating shaft by rotating the connecting block, thereby achieving adjustment of different angles and positions of the inclined support. At the same time, the connecting block, as the intermediary between the fixed structure and the limiting rod, can provide stable support and connection, ensuring the stability and reliability of the limiting rod during rotation.

[0025] Third, this utility model uses the rotation of the limiting rod to drive the rotation of the multi-segment connecting rod, and at the same time, it drives the position of the vertical rod in the slide groove. Under the fixing action of the bolts and nuts in the limiting groove, the position and angle of the limiting rod can be precisely controlled, so that the limiting rod can be used to limit the inclined support at a large angle, so as to ensure the docking accuracy between the inclined support and the inclined column, and improve the stability and safety of the entire structure.

[0026] IV. In this utility model, after the upper clamping plate, lower clamping plate and connecting structure of the first connecting piece and the second connecting piece are engaged with the fixing block, bolt and nut, the first connecting piece and the second connecting piece can be tightly clamped on the inclined column, so that the positioning connection device is not easy to loosen or deform when bearing external load, thus ensuring the safety of the structure. At the same time, the docking cavity formed between the connecting structures facilitates the docking and connection between the inclined support and the inclined column.

[0027] V. In this utility model, the upper and lower clamping plates are connected by a combination of upper and lower reinforcing bars and mounting plates, or by a single connecting plate. The former helps to reduce the weight of the positioning connection structure, while the latter can reduce the manufacturing process. However, both structures can enhance the overall stability and strength of the connection structure.

[0028] VI. The present invention uses a cylindrical rod as the limiting rod, which avoids the easy wear and tear of the inclined support when using a square rod. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.

[0043] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0044] Example 1

[0045] To address the issue of difficulty in precisely controlling the installation position and tilt angle of inclined supports during hoisting, due to factors such as wind force, limitations in the precision of hoisting equipment, and the skill level of operators, which can easily lead to deviations in the connection between the inclined support and the inclined column, thus affecting the stability and safety of the entire structure. Figure 1-6As shown, a positioning and connection device for skewed steel structures is provided, including a fixed structure 1 fixed to the skewed column, and a support structure 2 installed on the fixed structure to limit the skewed support and connect to the skewed column. The support structure 2 includes at least two limiting members 3, each including a grooved member 5 with a groove 4 fixedly installed on the fixed structure 1, a limiting rod 6 that rotates with the fixed structure 1, and a rotating member 7 passing through the groove 4 and connected to the limiting rod 6. Along the length of the grooved member 5, a limiting groove 24 is provided on the opposite side of the grooved member 5. The rotating member 7 passes through the groove 4 on both sides, and bolts 25 and nuts 8 that cooperate with the bolts 25 are slidably installed in the limiting groove. In practice, other methods to fix the rotating member 7 after rotation are not excluded.

[0046] In practice, based on the total station displacement measurement, the fixed structure is fixed at the designated position of the inclined column. With the nuts and bolts loosened, the limiting rod 6 in the support structure 2 is rotated counterclockwise or clockwise along the rotating shaft to the required angle. When the limiting rod 6 rotates, the rotating part 7 passing through the slide groove 4 rotates synchronously in the slide groove 4. After the limiting rod rotates to the required angle, the bolts on both sides of the rotating part 7 are moved to the position of contact with the rotating part 7. Then, the bolts are fixed to the limiting groove with nuts to fix the limiting rod and limit the angle. After fixing, the inclined support can be hoisted onto the limiting rod and connected to the inclined column. This embodiment achieves stable installation of the fixed structure on the inclined column. With the bolts loosened, the limiting rod in the support structure rotates in conjunction with the fixed structure, while the rotating component rotates in the sliding groove. When the limiting rod rotates to the required angle, the two bolts in the limiting groove move simultaneously and are fixed by the nuts to fix and limit the rotating component and the limiting rod, thereby fixing the angle of the limiting component. When hoisting the inclined support, the inclined support can be placed on the limiting rod, which facilitates angle limiting of the inclined support, thereby improving the installation accuracy between the inclined support and the inclined column and avoiding deviations that may occur in traditional hoisting methods. As a result, after installation, the stability and safety of the entire structure are improved, and the docking efficiency is also increased, greatly shortening the construction cycle.

[0047] Example 2

[0048] Based on Embodiment 1, the fixed structure 1 is provided with a connecting block 9, a rotating shaft 10 is rotatably mounted on the connecting block 9, and a limiting rod 6 is connected to the rotating shaft 10. By rotatably mounting the rotating shaft on the connecting block, the limiting rod can rotate around the rotating shaft, thereby achieving adjustment of different angles and positions of the inclined support. Simultaneously, the connecting block, acting as an intermediary between the fixed structure and the limiting rod, provides stable support and connection, ensuring the stability and reliability of the limiting rod during rotation. Alternatively, the limiting rod 6 can be rotatably connected to the rotating shaft 10, and the rotating shaft 10 can be fixedly connected to the connecting block 9.

[0049] Example 3

[0050] Based on Embodiment 2, the rotating component 7 includes a vertical rod 11 passing through the slide groove 4, and a multi-segment connecting rod 12 connected to the vertical rod 11 and the limiting rod 6. The rotation of the limiting rod drives the multi-segment connecting rod to rotate, simultaneously affecting the position of the vertical rod in the slide groove. Under the fixing action of bolts and nuts in the limiting groove, the position and angle of the limiting rod can be precisely controlled, facilitating the limiting of the inclined support at a large angle, ensuring the connection accuracy between the inclined support and the inclined column, and improving the stability and safety of the entire structure. The multi-segment connecting rod 12 can be as shown in the figure or other structures. A mounting plate can be provided on the slide groove component 5 on the opposite side of the fixed structure. A threaded rod is provided on the mounting plate, and a vertical groove is provided on the vertical rod 11 to slide and engage with the threaded rod. Two nuts are provided on the threaded rod to fix the vertical rod 11, with the two nuts located on both sides of the vertical rod.

[0051] Example 4

[0052] Based on embodiment 3, the fixing structure 1 includes a first connector 13 and a second connector 14 that cooperate with the inclined column. The two ends of the first connector 13 and the second connector 14 are fixed to the inclined column by bolts and nuts. A support structure 2 is provided on the first connector 13 or / and the second connector 14.

[0053] The first connector 13 and the second connector 14 each include an upper clamping plate 15 and a lower clamping plate 16, a connecting structure 17 connecting the two ends of the upper clamping plate 15 and the lower clamping plate 16, a limiting member 3 and a connecting block 9 disposed on the connecting structure 17, and a fixing block 18 connected to the connecting structure 17. The fixing block 18 is provided with a mounting hole 19. An inclined support docking cavity 20 is formed between the two connecting structures 17 on the first connector 13 and the second connector 14. After the upper clamping plate, lower clamping plate and connecting structure in the first connector and the second connector are engaged with the fixing block and bolts and nuts, the first connector and the second connector can be tightly clamped on the inclined column, so that the positioning connection device is not easy to loosen or deform when subjected to external loads, thus ensuring the safety of the structure. At the same time, the docking cavity formed between the connecting structures facilitates the docking and connection between the inclined support and the inclined column.

[0054] In practice, when the support structure 2 is installed on the first connector, the mating cavity 20 corresponds to the position where the inclined support and the inclined column are connected, and the first connector and the second connector are fixed by bolts and nuts through the mounting holes on the fixing block. The mating cavity 20 on the first connector can be inserted into the inclined support that is already fixed.

[0055] In practice, the upper clamp 15 or the lower clamp 16 can also be provided with an opening for removing the inclined support. Of course, other methods of removing the inclined support can also be provided.

[0056] Example 5

[0057] Based on embodiment 4, the connecting structure 17 includes an upper reinforcing bar 21 connected to the upper clamping plate 15, a lower reinforcing bar 22 connected to the lower clamping plate 16, and an mounting plate 23 connected to the upper reinforcing bar 21 and the lower reinforcing bar 22. A limiting member 3 and a connecting block 9 are disposed on the mounting plate 23. Alternatively, the connecting structure 17 includes a connecting plate connected to the upper clamping plate 15 and the lower clamping plate 16, with the limiting member 3 and the connecting block 9 disposed on the connecting plate. Connecting the upper and lower clamping plates through a combination of the upper and lower reinforcing bars and the mounting plate, or connecting the upper and lower clamping plates solely through the connecting plate, is advantageous. The former reduces the weight of the positioning connecting structure and facilitates installation and fixation, while the latter reduces manufacturing processes and allows for rapid prototyping. Both structures enhance the overall stability and strength of the connecting structure.

[0058] Example 6

[0059] Based on embodiment 5, the limiting rod 6 is a cylindrical rod. Using a cylindrical rod avoids the risk of wear and tear on the inclined support caused by using a square rod. Of course, a square rod can also be used.

[0060] The two limiting rods 6 supporting the same inclined support can also be connected by a connecting rod, which facilitates the synchronous rotation of the two limiting rods and effectively ensures their rotation angle.
