Description

Technical Field

[0001] This utility model belongs to the field of column grouting technology, and particularly relates to the concrete grouting structure of steel structure columns. Background Technology

[0002] With the rapid development of the construction industry, steel structure workshops have sprung up like mushrooms after rain. To reduce the steel content of steel structures, a method of grouting concrete inside steel tubes has emerged to enhance the load-bearing capacity of steel structures. In concrete-filled steel tube columns, the confinement of the concrete inside the steel tube puts the concrete in a triaxial compression state, which improves the compressive strength of the concrete; at the same time, the concrete inside the steel tube can effectively prevent local buckling of the steel tube. Studies have shown that the load-bearing capacity of concrete-filled steel tube columns is higher than the sum of the load-bearing capacities of corresponding steel tube columns and concrete columns. The interaction between the steel tube and the concrete changes the failure of the concrete inside the steel tube from brittle failure to plastic failure, significantly improving the ductility of the component and greatly enhancing its energy dissipation capacity, resulting in superior seismic performance. However, lattice steel tube columns require grouting fine aggregate concrete from bottom to top, which leads to concrete overflow after grouting, causing internal voids. This paper proposes a structure that can seal these voids within the columns. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a steel structure column cast-in-concrete structure, which solves the aforementioned problems.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a steel structure column concrete pouring structure, including a column, and further including: a sealing component for preventing concrete from flowing out; the sealing component includes a U-shaped plate, a base plate and a sliding frame, the U-shaped plate is slidably connected to the base plate, one end of the sliding frame is slidably connected to the base plate, the other end of the sliding frame is threadedly connected to a lead screw, and the lead screw is rotatably connected to the base plate.

[0005] Beneficial effects

[0006] This utility model provides a steel structure column concrete pouring structure, which has the following advantages compared with the prior art:

[0007] The user places the U-shaped plate and base plate onto the column, then presses the base plate firmly against the column. At this point, the grouting hole on the column is positioned within the base plate. The user then starts motor A, causing the shaft fixedly connected to the center of motor A to rotate synchronously. This causes the main gears fixedly connected to both ends of the shaft to rotate synchronously, pushing the rack meshing with it. The U-shaped plate then begins linear movement along its connection point with the base plate, thus clamping the column tightly together. The adhesive strip on the U-shaped plate further enhances the stability of the connection, preventing slippage during use and ensuring effective sealing of the column. The user then injects grout through the grouting hole on the column. After grouting, the user removes the grouting pipe and starts motor B, causing the lead screw fixedly connected to its center to rotate at a constant speed, driving the threaded section... The connecting slide frame begins to move linearly along the connection point with the substrate, driving the sealing plate to the grouting hole on the column, aligning its upper rubber sleeve with the grouting hole. At this point, the motor is started, causing the gear to drive the guide rod fixedly connected to its shaft to rotate synchronously. Simultaneously, the cams fixedly connected to both sides of the guide rod begin to rotate synchronously, causing the rotating drum connected to the cam to gradually contact the sealing plate. During contact, the rotation of the drum reduces the friction, pushing the rubber sleeve on the sealing plate into the grouting hole, thus sealing the grouting hole. At the same time, the sealing plate adheres tightly to the surface of the column, further increasing the tightness of the seal. The soft padding layer on the sealing plate effectively fills the gap between the sealing plate and the column, preventing grout from flowing out. During this process, the sealing plate can stretch the spring to deform, so that when the rotating drum stops supporting the sealing plate, the spring can pull the sealing plate back to its original position, facilitating the removal of the device.

[0015] Sealing component 2 is used to prevent concrete from flowing out;

[0016] The sealing component 2 includes a U-shaped plate 201, a base plate 202, and a sliding frame 203. The U-shaped plate 201 is slidably connected to the base plate 202. One end of the sliding frame 203 is slidably connected to the base plate 202, and the other end of the sliding frame 203 is threadedly connected to a lead screw 303. The lead screw 303 is rotatably connected to the base plate 202.

[0017] For the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific U-shaped plate 201 described in the above embodiments. For example, the U-shaped plate 201 is wrapped with an adhesive strip on its inner side. The purpose of this setting is to provide a buffer for the contact between the U-shaped plate 201 and the column 101, thereby increasing the stability of their connection.

[0018] Specifically, a sealing plate 205 is slidably connected to the sliding frame 203, and a spring 204 is fixedly connected to the sealing plate 205. The other end of the spring 204 is fixedly connected to the sliding frame 203.

[0019] For the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific sealing plate 205 described in the above embodiments. For example, the rubber sleeve at the axis of the sealing plate 205 should have the same diameter as or greater than the diameter of the concave hole on the column 101. The purpose of this setting is to facilitate the increase of the sealing effect on the column 101 through this setting, and the rubber sleeve should have appropriate hardness.

[0020] Specifically, a guide rod 206 is rotatably connected to the base plate 202, and a cam 207 is fixedly connected to both ends of the guide rod 206. A rotating cylinder 208 is rotatably connected to the cam 207.

[0021] For the above examples, those skilled in the art should know that when implementing the above technical solutions, it is not limited to the specific rotating drum 208 described in the above embodiments. For example, the connection between the rotating drum 208 and the cam 207 should be further hardened and reinforced. The purpose of this setting is to facilitate the avoidance of its breakage under stress.

[0022] Specifically, a gear 209 is fixedly connected to the guide rod 206, the gear 209 meshes with the transmission gear 301, the transmission gear 301 is fixedly connected to the output shaft of the motor 302, and the motor 302 is fixedly connected to the base plate 202.

[0023] For the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific motor 302 described in the above embodiments. For example, the motor 302 should have multiple adjustable speeds. The purpose of this setting is to facilitate the adjustment of the rotation speed of the cam 207 through this setting.

[0024] Specifically, one end of the lead screw 303 is fixedly connected to the output shaft of the motor B304, and the motor B304 is fixedly connected to the base plate 202.

[0025] For the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific lead screw 303 described in the above embodiments. For example, the lead screw 303 can be a reciprocating lead screw. The purpose of this setting is that when the slider connected to the thread on the reciprocating lead screw moves to one end, the sliding direction of the slider can be quickly changed by continuing to control the lead screw to rotate in the same direction.

[0026] Specifically, racks 305 are fixedly connected to both sides of the U-shaped plate 201, and the racks 305 are meshed with the main gear 306, which is fixedly connected to the shaft 307.

[0027] Regarding the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific shaft 307 described in the above embodiments. For example, the shaft 307 is made of a high-hardness material. The purpose of this arrangement is to facilitate the prevention of breakage under stress.

[0028] Specifically, the shaft 307 is rotatably connected to the base plate 202, one end of the shaft 307 is fixedly connected to the output shaft of the motor A308, and the motor A308 is fixedly connected to the base plate 202.

[0029] For the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific substrate 202 described in the above embodiments. For example, the substrate 202 is provided with anti-slip rubber strips. The purpose of this setting is to facilitate pressing and positioning the substrate 202 on the column 101 to prevent it from sliding.

[0030] In this embodiment of the invention, the user places the U-shaped plate 201 and the base plate 202 onto the column 101, and then presses the base plate 202 against the column 101. At this time, the grouting hole on the column 101 is located within it. The user can then start the motor A308, causing the shaft 307 fixedly connected to the shaft center of the motor A308 to rotate synchronously. At this time, the main gears 306 fixedly connected to both ends of the shaft 307 rotate synchronously, causing the main gears 306 to push the rack 305 meshing with it, and thus opening the U-shaped plate 201. The U-shaped plate 201 and the base plate 202 move linearly along their connection point, thereby clamping the column 101 together. The adhesive strip on the U-shaped plate 201 further increases the stability of the connection, preventing slippage during use and ensuring effective sealing of the column 101. The user then injects grout through the injection hole on the column 101. After grouting, the user removes the injection pipe and starts the motor B304, causing the lead screw 303, fixedly connected to its shaft, to rotate at a constant speed, driving the column... The threaded sliding frame 203 begins to move linearly along its connection with the substrate 202, moving the sealing plate 205 to the grouting hole on the column 101, aligning its upper rubber sleeve with the grouting hole. At this point, the motor 302 is started, causing the gear 209 to drive the guide rod 206, fixedly connected to its shaft, to rotate synchronously. Simultaneously, the cams 207, fixedly connected to both sides of the guide rod 206, begin to rotate synchronously, causing the rotating drum 208, rotatably connected to the cams 207, to gradually contact the sealing plate 205. Simultaneously, during contact, the rotating drum 208... 8. Rotation reduces the friction it experiences, at which point the rubber sleeve on the sealing plate 205 is pushed into the grouting hole, thereby sealing the grouting hole. At the same time, the sealing plate 205 is tightly attached to the surface of the column 101, further increasing the tightness of the seal. Meanwhile, the soft padding layer on the sealing plate 205 can effectively fill the gap between the sealing plate 205 and the column 101, preventing the grout from flowing out. During this process, the sealing plate 205 can stretch the spring 204 to deform it, so that when the rotating drum 208 stops supporting the sealing plate 205, the spring 204 can pull the sealing plate 205 back to its original position, making it easy to remove the device.

[0031] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0032] The term "fixed connection" as used in this application refers to a connection in which parts or components are fixed without any relative movement. This includes both detachable and non-detachable connections.

[0033] (1) Detachable connection: The components are fixed together using screws, splines, wedges, etc. This type of connection can be disassembled during maintenance without damaging the parts. However, the specifications of the connecting parts used must be correct (such as the length of the bolts, keys, wedges) and properly tightened.

[0034] (2) Non-removable connections: These mainly refer to welding, riveting, and tenon joints. Since disassembly requires forging, sawing, or oxyacetylene cutting for repair or replacement, the parts generally cannot be reused. At the same time, attention should be paid to process quality, technical inspection, and remedial measures (such as correction and polishing) during connection.

[0035] The sliding connection referred to in this application means that the component can slide along a linear trajectory, and the hinge referred to in this application means that the component can rotate along an axial constraint.

[0036] In some cases, the sliding connection and hinge referred to in this application may also be damped, enabling the component to maintain in the desired position.
