Description

Technical Field

[0001] This utility model relates to the technical field of connection structures, specifically a connection structure for the installation of heavy steel structures. Background Technology

[0002] Heavy steel refers to steel with large cross-sectional dimensions, heavy weight per unit length, and extremely high load-bearing capacity. It is mainly used in key structural parts that need to withstand huge loads or provide strong support. Heavy steel structures are widely used in super high-rise buildings, long-span bridges, and heavy industrial facilities. Its hundred-ton-level components need to be connected with high-strength bolts to achieve millimeter-level positioning accuracy. As the core link of load transfer, the connection structure directly determines the seismic resistance, fatigue resistance, and service safety of the overall structure.

[0003] When installing heavy steel structures, bolts are generally used for fixing. When placing the steel structures together, it is necessary to move the components of the steel structures to align their bolt holes. However, heavy steel structures are very heavy, and installation is usually carried out by cranes. When moving the steel structures in the air, it is not easy to position them due to the inertia of the steel structures, and it takes a long time to align the threaded holes between the steel structures, thus reducing the efficiency of steel structure installation. To address these issues, we provide a connection structure for the installation of heavy steel structures. Utility Model Content

[0004] 1) Technical problems to be solved This utility model proposes a connection structure for the installation of heavy steel structures. By setting up components such as limiting plates and insert plates, it solves the problems of existing steel structures being inconvenient to position and requiring a long time to align the threaded holes between steel structures, thus reducing the efficiency of steel structure installation.

[0005] (ii) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a connection structure for installing heavy steel structures, comprising a fixed cylinder, a support plate fixedly connected to the outer surface of the fixed cylinder, a limit plate fixedly connected to the upper surface of the support plate, and one side of the limit plate fixedly connected to the fixed cylinder; an insert plate detachably connected to the inner side of the limit plate, an mounting plate fixedly connected to the upper surface of the insert plate, and a lower surface of the mounting plate detachably connected to the limit plate; a positioning mechanism is provided at the lower part of the limit plate, an adjustment mechanism is provided inside the support plate, and a rolling mechanism is provided at the upper end of the adjustment mechanism.

[0006] Furthermore, a reinforcing rod is fixedly connected to the upper surface of the support plate, and the upper end of the reinforcing rod is fixedly connected to the limiting plate.

[0007] Furthermore, the positioning mechanism includes a fixing block, one side of which is fixedly connected to a fixing cylinder, a spring is fixedly connected to the upper surface of the fixing block, and a plug rod is fixedly connected to the upper end of the spring.

[0008] Furthermore, the inner wall of the fixing block is slidably connected to the insertion rod, the outer surface of the insertion rod is slidably connected to the limiting plate, and the outer surface of the insertion rod is also slidably connected to the mounting plate.

[0009] Furthermore, the adjustment mechanism includes a threaded rod, the outer surface of which is threadedly connected to a support plate, and an adjustment plate is rotatably connected to the upper end of the threaded rod.

[0010] Furthermore, a sliding rod is fixedly connected to the lower surface of the adjusting plate, and the outer surface of the sliding rod is slidably connected to the support plate.

[0011] Furthermore, the rolling mechanism includes a fixed ring, the lower surface of which is fixedly connected to the adjusting plate, and a roller is rotatably connected to the inner wall of the fixed ring.

[0012] (iii) Beneficial effects: Compared with existing technologies, this connection structure for heavy steel structure installation has the following advantages: 1. This heavy-duty steel structure installation connection structure, through the setting of components such as limiting plates and insert plates, places the insert plate between two limiting plates. The inclined limiting plates position the insert plate, aligning the mounting plate with the limiting plates and ensuring that the bolt holes on both are in a straight line. Then, a positioning mechanism is used to temporarily restrict the position of the mounting plate and the limiting plates. At this time, the bolt holes on the limiting plates are vertically aligned with the bolt holes on the mounting plate and the insert plate. Then, an adjusting mechanism drives the rolling mechanism to move downward, aligning the bolt holes on the limiting plates with the bolt holes on the mounting plate and the insert plate and fitting them together to secure the bolts. This solves the problem that existing steel structures are inconvenient to position and require a long time to align the threaded holes between steel structures, thus reducing the efficiency of steel structure installation.

[0013] 2. This heavy-duty steel structure installation connection structure, through the setting of components such as a rolling mechanism, allows the rollers to contact the insert plate to form support, preventing the insert plate and mounting plate from directly contacting the limiting plate. This significantly reduces friction during sliding, facilitating the sliding of the mounting plate towards the fixed cylinder. By rotating the threaded rod, the adjusting plate moves downward, causing the rolling mechanism to move downward as well. The fixing ring and rollers no longer support the insert plate. At this point, the mounting plate and insert plate move downward under their own weight, closely fitting with the limiting plate. The bolt holes of all three are perfectly aligned. Finally, the end of the horizontal I-beam is fixed to the mounting plate with large hexagonal high-strength bolts, completing the firm connection between the horizontal I-beam and the fixed cylinder, achieving efficient installation and fixing of the heavy-duty steel structure.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1-7As shown, this utility model provides a technical solution: a connection structure for installing heavy steel structures, including a fixed cylinder 1, a support plate 2 fixedly connected to the outer surface of the fixed cylinder 1, a limit plate 3 fixedly connected to the upper surface of the support plate 2, and one side of the limit plate 3 fixedly connected to the fixed cylinder 1; an insert plate 5 detachably connected to the inner side of the limit plate 3, an mounting plate 4 fixedly connected to the upper surface of the insert plate 5, and a lower surface of the mounting plate 4 detachably connected to the limit plate 3; a positioning mechanism 6 is provided at the lower part of the limit plate 3, an adjustment mechanism 7 is provided inside the support plate 2, and a rolling mechanism 8 is provided at the upper end of the adjustment mechanism 7; the fixed cylinder 1 is rectangular, and its position... A partition plate is integrally connected in the middle, dividing the structure into upper and lower rectangular tubes. This allows the bottom of the upper H-beam and the top of the lower H-beam to be fitted together and secured with bolts (high-strength hexagonal bolts are acceptable). The fixing tube 1, support plate 2, and limiting plate 3 are all welded together. The support plate 2 supports and secures the limiting plate 3 and its mounting plate 4 and insert plate 5. The end of the horizontal H-beam is fixed to the upper surface of the mounting plate 4 with high-strength hexagonal bolts, thus fixing the horizontal H-beam to the fixing tube 1 for a secure connection. There are three sets of limiting plates 3. The assembly includes two mirror-aligned limiting plates 3. During hoisting, the mounting plate 4 is placed from top to bottom on top of the limiting plates 3, positioning the insert plate 5 between the two mirror-aligned limiting plates 3. The three sets of limiting plates 3 correspond to installation in three directions. The appropriate limiting plate 3 is selected on-site as needed. The rolling mechanism 8 is located at the bottom of the insert plate 5 to support it, preventing contact between the insert plate 5 and the mounting plate 4 and the limiting plates 3, thus reducing friction and facilitating sliding of the insert plate 5. The inclined limiting plates 3 position the insert plate 5, aligning the mounting plate 4 with the limiting plates 3 so that their bolt holes are aligned. Then, the mounting plate 4 is pushed... The mounting plate 4 moves closer to the fixed cylinder 1. When the insert plate 5 slides to the innermost position, it is positioned by the positioning mechanism 6, which temporarily restricts the position of the mounting plate 4 and the limiting plate 3, preventing the mounting plate 4 from moving horizontally. At this time, the bolt holes on the limiting plate 3 are aligned vertically with the bolt holes on the mounting plate 4 and the insert plate 5. Then, the rolling mechanism 8 is driven downward by the adjusting mechanism 7, so that the rolling mechanism 8 no longer holds the insert plate 5, allowing the mounting plate 4 and the insert plate 5 to move downward and contact the limiting plate 3. At this time, the bolt holes on the limiting plate 3 are aligned vertically with the bolt holes on the mounting plate 4 and the insert plate 5 and fit together to be fixed with the bolts.

[0019] A reinforcing rod 9 is fixedly connected to the upper surface of the support plate 2. The upper end of the reinforcing rod 9 is fixedly connected to the limiting plate 3. The support plate 2 and the limiting plate 3 are connected together by the reinforcing rod 9 to increase their firmness.

[0020] The positioning mechanism 6 includes a fixing block 601, one side of which is fixedly connected to the fixing cylinder 1. A spring 603 is fixedly connected to the upper surface of the fixing block 601, and an insertion rod 602 is fixedly connected to the upper end of the spring 603. The inner wall of the fixing block 601 is slidably connected to the insertion rod 602, and the outer surface of the insertion rod 602 is slidably connected to the limiting plate 3 and the mounting plate 4. The insertion rod 602 can penetrate the limiting plate 3 and the mounting plate 4 to facilitate positioning of both. For positioning, a circular plate (unmarked) is fixedly connected to the outer surface of the insertion rod 602. The upper end of the spring 603 is fixed to the circular plate to provide elastic force for the insertion rod 602 to move upward. When the mounting plate 4 moves from top to bottom, if the bolt holes are not aligned, the lower surface of the mounting plate 4 first presses the insertion rod 602 downward so that the upper surface of the insertion rod 602 is not higher than the upper surface of the mounting plate 4. When the mounting plate 4 moves to the designated position, the insertion rod 602 is inserted into the inner wall of the mounting plate 4 under the action of the elastic force, which facilitates positioning.

[0021] The adjusting mechanism 7 includes a threaded rod 701, the outer surface of which is threadedly connected to the support plate 2. An adjusting plate 702 is rotatably connected to the upper end of the threaded rod 701. When the threaded rod 701 rotates, it can drive the adjusting plate 702 to move up or down.

[0022] A sliding rod 703 is fixedly connected to the lower surface of the adjusting plate 702. The outer surface of the sliding rod 703 is slidably connected to the support plate 2. When the adjusting plate 702 moves up and down, the sliding rod 703 restricts the adjusting plate 702 to prevent the adjusting plate 702 from shifting or rotating.

[0023] The rolling mechanism 8 includes a fixed ring 801, the lower surface of which is fixedly connected to the adjusting plate 702. A roller 802 is rotatably connected to the inner wall of the fixed ring 801. The roller 802 can rotate, which can reduce the friction between the insert plate 5 and the support plate 2, so as to facilitate the sliding of the insert plate 5.

[0024] Working principle: The fixed cylinder 1 serves as the core connecting component. Its rectangular cylindrical structure and the integrated partition in the middle can respectively fit the bottom of the upper I-beam and the top of the lower I-beam. The upper and lower I-beams are initially connected and fixed by large hexagonal high-strength bolts, providing basic support for the overall structure.

[0025] During the connection between the horizontal I-beam and the fixed cylinder 1, the support plate 2 provides stable support for the limiting plate 3 and the subsequently installed mounting plate 4 and insert plate 5; the reinforcing rod 9 further enhances the firmness of the connection between the support plate 2 and the limiting plate 3. The limiting plate 3 is in an inclined state. When the insert plate 5 is placed between the two limiting plates 3, the inclined inner surface can initially position the insert plate 5, so that the bolt holes of the mounting plate 4 and the limiting plate 3 are roughly in the same straight line, laying the foundation for subsequent precise alignment. When the mounting plate 4 is placed, it is positioned from top to bottom above the limiting plate 3, and the insert plate 5 then enters between the two limiting plates 3. At this time, the rolling mechanism 8 located at the bottom of the insert plate 5 plays a role, and its roller 802 contacts the insert plate 5 to form support, so that the insert plate 5 and the mounting plate 4 do not directly contact the limiting plate 3, which greatly reduces the friction during the sliding process and makes it easier to push the mounting plate 4 to drive the insert plate 5 to slide closer to the fixed cylinder 1. When the mounting plate 4 moves from top to bottom, if the bolt holes are not aligned, the lower surface of the mounting plate 4 first presses the insert rod 602 downward, so that the upper surface of the insert rod 602 is not higher than the upper surface of the mounting plate 4. When the insert plate 5 slides to the innermost position, the insert rod 602 in the fixed block 601 moves upward under the elastic force of the spring 603, passes through the limiting plate 3 and inserts into the mounting plate 4, realizing the temporary position restriction between the mounting plate 4 and the limiting plate 3, preventing the mounting plate 4 from moving horizontally, and ensuring that the bolt holes on the limiting plate 3, the mounting plate 4 and the insert plate 5 are accurately aligned. Subsequently, the adjusting mechanism 7 is activated, driving the adjusting plate 702 downwards via the rotating threaded rod 701. This causes the rolling mechanism 8 to move downwards as well, and the fixing ring 801 and roller 802 no longer support the insert plate 5. At this time, the mounting plate 4 and the insert plate 5 move downwards under their own weight, fitting tightly against the limiting plate 3. The bolt holes of the three are perfectly aligned. Finally, the end of the horizontal I-beam is fixed to the mounting plate 4 using large hexagonal high-strength bolts, completing the firm connection between the horizontal I-beam and the fixing cylinder 1, and achieving efficient installation and fixing of the heavy steel structure.
