Description

Technical Field

[0001] This application belongs to the field of high-rise building connection structure technology, specifically a connection clamp for the overall vertical connection of multi-story H-shaped steel beams in a suspended structure. Background Technology

[0002] A suspended structure is a structural system that transfers floor loads to a transfer floor via hangers, and then from the transfer floor to the main structure and finally to the foundation. Because it can fully utilize the performance of steel, the size of the components is greatly reduced, resulting in a good architectural space effect. It is widely used in high-rise buildings. When constructing suspended floors, the method of assembling them on the ground and then lifting them to the corresponding positions for installation is often adopted. When constructing multi-story suspended floors, it is necessary to lift the components of multiple floors as a whole, so multiple floors need to be connected as a whole. The common method is to splice the steel beams of multiple floors, connect each floor with short welded columns, hoist the whole structure to the corresponding floor height, and then cut the welded positions of the steel beams and short columns to separate the floors.

[0003] Chinese invention patent 2018115621192 discloses a clamp for hoisting H-shaped steel beams and its hoisting method, belonging to the field of construction equipment technology. The clamp for hoisting H-shaped steel beams is applied to the hoisting of H-shaped steel beams and includes a wire rope and hoisting clamps symmetrically distributed on the H-shaped steel beam. The hoisting clamps are rectangular open hooks, including hoisting holes and integrated slots and hook holding ends. The clamps have poor clamping and fixing properties and low clamping stability.

[0004] The aforementioned short column welding connection method may cause the steel beam to be subjected to uneven high temperature and cooling during the welding process, resulting in residual welding stress and residual deformation in the structure; this has a certain impact on the load-bearing capacity, stiffness and service performance of the structure.

[0005] Furthermore, the installation position of the H-beam cannot be determined during the installation of the H-beam, so the H-beam will tilt inside the connecting clamp, thereby reducing the stability of the subsequent lifting of the H-beam. In the existing technology, the placement accuracy of the H-beam needs to be detected and adjusted by human eyes, which increases the installation difficulty and accuracy.

[0006] When the connecting clamps fix the H-beam and lift it, if the H-beam is subjected to wind force or load force on one side and tilts and sways inside the connecting clamps, it will not only reduce the lifting stability of the H-beam, but also damage the internal structure of the connecting clamps.

[0007] If the connecting clamp suddenly falls during the lifting of the H-beam, the connecting clamp will cause the H-beam to fall simultaneously. When the connecting clamp causes the H-beam to come into contact with and collide with the ground, the H-beam will detach from the connecting clamp due to its own inertia. The structure at the end of the H-beam will directly threaten the road surface or personnel safety and pose a risk of major personal safety accidents. Summary of the Invention

[0038] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0039] First Embodiment

[0040] like Figure 1-6 As shown, the connecting clamp for the vertical connection of the multi-story H-shaped steel beams in the suspension structure includes a first connector 1. A controller is provided on one side of the first connector 1, which electrically controls various electrical components. A second connector 2 is inserted into the bottom of the first connector 1. The first connector 1 and the second connector 2 are spliced ​​and installed. An H-shaped steel beam 3 is provided between the first connector 1 and the second connector 2. The upper and lower positions of the H-shaped steel beam 3 are spliced ​​and fixed by the first connector 1 and the second connector 2. Sliding plates 4 are provided on both the upper and lower sides of the H-shaped steel beam 3. Multiple sets of sliding plates 4 work together to clamp and fix the two sides of the H-shaped steel beam 3, thereby effectively improving the installation accuracy and installation stability of the H-shaped steel beam 3.

[0041] The first connecting member 1 includes a first horizontal plate 106, which presses against the top of the H-beam 3 to ensure the fixed and limiting effect of the H-beam 3. Two sets of insertion sleeves 105 are symmetrically arranged on both sides of the bottom of the first horizontal plate 106. The insertion sleeves 105 are mainly used for insertion and fixing. Multiple sets of connecting holes 102 are evenly opened on one side of the insertion sleeve 105, which mainly limit the position of the insertion sleeve 105, thereby ensuring the stability of the insertion sleeve 105 in actual use and the fixing effect of the first horizontal plate 106 on the H-beam 3. A first inner groove 107 is opened at the bottom of the first horizontal plate 106. The first inner groove 107 is located at the... The recessed position of the horizontal plate 106 allows the sliding plate 4 inside the first inner groove 107 to move and clamp and fix the top two sides of the H-shaped steel beam 3. The two side walls of the first inner groove 107 are provided with sliding grooves 101, which match the upper sliding plate 4. The sliding grooves 101 are mainly used for the upper sliding plate 4 to move. Multiple sets of positioning holes 103 are evenly provided at the bottom of the sliding groove 101. The bottom of the positioning holes 103 penetrates the first horizontal plate 106, and the positioning holes 103 are mainly used to fix the position of the sliding plate 4. Multiple sets of through holes 104 are evenly provided inside the first horizontal plate 106. The setting of the through holes 104 ensures the stacking and clamping effect of multiple sets of the connecting clamps.

[0042] The second connecting member 2 includes a second horizontal plate 205, which supports and fixes the bottom of the H-beam 3. Two sets of insert rods 206 are symmetrically arranged on both sides of the top of the second horizontal plate 205. The insert rods 206 are inserted into the insert sleeve 105. Therefore, in actual use, the insert rods 206 are inserted into the insert sleeve 105 to adjust the position of the first horizontal plate 106, so as to ensure that the first horizontal plate 106 and the top of the H-beam 3 are pressed and contacted each other.

[0043] Multiple sets of mating holes 201 are evenly opened on one side of the insertion rod 206. The connecting hole 102 and the mating hole 201 are matched and connected by the mating bolt 6. When the connecting hole 102 and the mating hole 201 are matched and spliced, the thread is limited by the mating bolt 6, which further improves the clamping and fixing effect of the first horizontal plate 106 and the second horizontal plate 205 on the internal H-shaped steel beam 3.

[0044] The top of the second horizontal plate 205 is provided with a second inner groove 207, and the bottom groove 8 is provided inside the second inner groove 207. The height of the second inner groove 207 is lower than that of the second horizontal plate 205, and the second inner groove 207 is mainly used for the movement of the sliding plate 4. The inner walls on both sides of the second inner groove 207 are provided with moving grooves 202. The moving grooves 202 match the sliding plate 4 below, so the sliding plate 4 below can move along the moving grooves 202 and clamp and fix the bottom sides of the H-shaped steel beam 3. The top of the moving grooves 202 is provided with multiple sets of matching holes 203. The top of the matching holes 203 penetrates the second horizontal plate 205, and the matching holes 203 are mainly used for fixing and limiting the sliding plate 4 below. The interior of the second horizontal plate 205 is provided with multiple sets of splicing holes 204. The through holes 104 match the splicing holes 204 and are connected by alignment bolts 5. The adjacent first horizontal plate 106 and second horizontal plate 205 are threadedly fixed by alignment bolts 5, further realizing the multi-story limiting and fixing effect.

[0045] Two sets of circular holes 7 are symmetrically provided on both sides of the sliding plate 4. The upper circular hole 7 is connected to the positioning hole 103 by a positioning bolt, and the lower circular hole 7 is connected to the matching hole 203 by a positioning bolt. When the upper sliding plate 4 moves to a suitable position inside the positioning hole 103 and clamps and fixes the top two sides of the H-beam 3, and the lower sliding plate 4 moves to a suitable position inside the matching hole 203 and clamps and fixes the bottom two sides of the H-beam 3, the upper sliding plate 4 and the positioning hole 103 are threaded together by the positioning bolts, and the lower sliding plate 4 and the matching hole 203 are threaded together, which further improves the limiting function of the sliding plate 4 and the clamping and fixing effect on both sides of the H-beam 3.

[0046] In use, first install the bottom steel beam, place the H-beam 3 horizontally on top of the second horizontal plate 205, and adjust the position of the lower sliding plate 4 according to the cross-sectional width of the H-beam 3 through the moving groove 202. When the distance between the two lower sliding plates 4 is adjusted to be the same as the cross-sectional width of the H-beam 3, the two lower sliding plates 4 clamp and fix the bottom sides of the H-beam 3. Then connect the lower sliding plates 4 to the fixed matching hole 203 with positioning screws to clamp the lower flange of the H-beam 3.

[0047] Then, the first connector 1 is placed vertically on the second connector 2, and the first horizontal plate 106 is moved to the top of the second horizontal plate 205. At the same time, the insertion sleeve 105 and the insertion rod 206 are inserted and slid downwards. Meanwhile, according to the cross-sectional height of the H-beam 3, the upper and lower positions of the first connector 1 are adjusted until the distance between the bottom of the first horizontal plate 106 and the top of the second horizontal plate 205 is adjusted to be the same as the cross-sectional height of the H-beam 3. This completes the clamping and fixing of the upper and lower sides of the H-beam 3 by the first horizontal plate 106 and the second horizontal plate 205, further improving the installation accuracy and stability of the H-beam 3. Then, the connecting holes 102 and the mating holes 201 are aligned with each other, and the connecting holes 102 on the insertion sleeve 105 and the connecting holes 102 on the insertion rod 206 are connected by the mating bolts 6, thereby improving the insertion and fixing effect of the insertion sleeve 105 and the insertion rod 206.

[0048] Then, adjust the position of the upper sliding plate 4 according to the cross-sectional width of the H-beam 3. Specifically, move the upper sliding plate 4 along the sliding groove 101. When the distance between the two upper sliding plates 4 is adjusted to be the same as the cross-sectional width of the H-beam 3, connect the sliding plate 4 to the positioning hole 103 with positioning screws, thereby fixing the H-beam 3 in the position inside the connecting clamp.

[0049] When installing the upper steel beam, the splicing hole 204 inside the second horizontal plate 205 of the upper steel beam is connected to the through hole 104 inside the first horizontal plate 106 of the bottom steel beam by the alignment bolt 5, thereby fixing the position of the second connecting piece 2 of the upper steel beam. Then, repeat the above steps to complete the connection between the upper steel beam and the bottom steel beam, and finally complete the splicing process.

[0050] This device effectively improves the clamping accuracy and stability of the sliding plate 4 on the H-beam 3, ensuring the support force and tightness of the H-beam 3 in actual use, preventing the H-beam 3 from shaking inside the first connector 1 and the second connector 2, thus reducing its strength. It is more adaptable and meets the clamping effect for H-beams 3 of different widths. At the same time, it can also adjust the gap between the first connector 1 and the second connector 2 according to the height of the H-beam 3, thereby ensuring the clamping and fixing effect of the first connector 1 and the second connector 2 on the height direction of the H-beam 3, further improving the support and stability of the H-beam 3. It can also realize the process of splicing adjacent first connector 1 and second connector 2 to increase the floor height, meeting the requirements of multi-story suspended structures, with higher stability and stronger splicing direction.

[0051] Second Embodiment

[0052] like Figure 7-9As shown, when the H-beam 3 is placed on top of the second horizontal plate 205 and installed, if the position of the H-beam 3 is skewed, it will not only reduce the subsequent installation accuracy and stability of the H-beam 3, but also affect the smoothness of the subsequent lifting of the H-beam 3. The aforementioned devices lack precise detection and adjustment functions for the position of the H-beam 3, and relying solely on manual visual identification is difficult, inaccurate, and cannot meet the requirements for rapid installation. Furthermore, when the H-beam 3 is lifted using connecting clamps after installation, if the top or bottom of the H-beam 3 is subjected to a large load or wind force, the H-beam 3 will tilt and sway inside the first connecting member 1 and the second connecting member 2. This not only reduces the supporting stability of the H-beam 3 on the suspension structure, but also applies compressive force to the inner walls of the first connector 1 and the second connector 2, causing damage to their internal structure. When the left and right sides of the H-beam 3 are subjected to wind force, which exerts a force on the sliding plate 4 on the other side, the sliding plate 4, which is fixed by the round hole 7 and the positioning bolt alone, cannot meet the reverse support requirements of the H-beam 3. This can easily cause damage to the sliding plate 4 and reduce the clamping and fixing effect on the side wall of the H-beam 3. When the connecting clamp suddenly falls during the lifting of the H-beam 3, the rigid material of the H-beam 3 itself and the sharp edge structure at the end will fall directly to the ground and threaten the safety of the road surface or personnel.

[0053] To solve the above problems, the connecting clamp for the overall lifting and vertical connection of the multi-story H-shaped steel beams of the suspension structure also includes: multiple sets of bottom grooves 8 are evenly provided in the inner bottom of the second connecting member 2, and a support rod 9 is slidably connected inside the bottom groove 8. The support rod 9 can move up and down along the bottom groove 8. A connecting pipe 11 is connected to the bottom of the bottom groove 8. The other end of the connecting pipe 11 passes through the inner bottom of the second connecting member 2 and is connected to a hose 12. When the support rod 9 moves up and down along the bottom groove 8, the gas inside the bottom groove 8 can flow into the hose 12 along the connecting pipe 11.

[0054] A connecting spring 10 is provided at the bottom of the bottom groove 8. The top of the connecting spring 10 is fixedly connected to the bottom of the support rod 9. The setting of the connecting spring 10 further improves the elastic reset performance of the support rod 9 inside the bottom groove 8. The connecting pipe 11 is located inside the second horizontal plate 205. The connecting pipe 11 has a concave structure, so the other end of the connecting pipe 11 can extend along the top of the second horizontal plate 205. The diameter of the connecting pipe 11 is smaller than the diameter of the bottom groove 8. When the gas inside the bottom groove 8 is discharged along the connecting pipe 11, a large amount of gas will enter the hose 12 for circulation. The hose 12 is elastic. The setting of the hose 12 ensures that it can deform, further improving the adaptability of the connecting clamp.

[0055] Multiple sets of side grooves 13 are evenly opened on the facing end faces of the lower sliding plate 4. Specifically, this scheme mainly studies the clamping and adjustment function of the lower sliding plate 4 on the H-shaped steel beam 3. The inner wall of each side groove 13 is equipped with an electromagnet 14. A magnetic push rod 16 is slidably connected inside the side groove 13. The magnetic properties of the facing end faces of the electromagnet 14 and the magnetic push rod 16 are the same. When the electromagnet 14 is energized and has magnetism, the magnetic repulsion force of the electromagnet 14 on the magnetic push rod 16 drives the magnetic push rod 16 to move outward along the side groove 13. The side wall of the electromagnet 14 is equipped with a side spring 15. The other end of the side spring 15 is fixedly connected to the side wall of the magnetic push rod 16. The setting of the side spring 15 further improves the elastic reset performance of the magnetic push rod 16. Thus, when the electromagnet 14 is de-energized, the magnetic push rod 16 is driven to move in the opposite direction and move along the side groove 13 towards the end close to the electromagnet 14 under the elastic force of the side spring 15.

[0056] The other end of the magnetic push rod 16 passes through the side groove 13 and is provided with a vertical plate 17. The vertical plate 17 mainly serves as an intermediate component. An intermediate tube 18 is provided inside the vertical plate 17. The bottom of the intermediate tube 18 is connected to the other end of the hose 12, so that the gas inside the hose 12 can enter the intermediate tube 18 for circulation. Specifically, in actual use, at least four sets of bottom grooves 8 are provided on the top of the second horizontal plate 205, and the bottom grooves 8 are evenly and symmetrically distributed on the top of the second horizontal plate 205. At the same time, the width of the four sets of bottom grooves 8 is smaller than the width of the H-shaped steel beam 3, which can effectively ensure that the H-shaped steel beam 3 is placed directly on the top of the support rod 9. For support adjustment, in particular, four sets of side grooves 13 are opened, and two sets of sliding plates 4 are symmetrically opened on their opposite ends. Moreover, the hose 12 is connected to the middle tube 18 inside the nearest vertical plate 17. For example, the hose 12 located on the left front side is connected to the middle tube 18 inside the front vertical plate 17 of the lower left sliding plate 4. This arrangement further improves the response speed and response efficiency of the support rod 9 and the magnetic push rod 16. The top of the support rod 9 is provided with a friction pad. The setting of the friction pad further improves the support stability and friction limit of the support rod 9 on the top H-shaped steel beam 3.

[0057] A corrugated pressure tube 19 is provided on the side of the vertical plate 17 away from the sliding plate 4. The corrugated pressure tube 19 is elastic and expands in the lateral direction. The other end of the intermediate tube 18 is connected to the corrugated pressure tube 19, so the gas inside the hose 12 can be connected to the corrugated pressure tube 19 through the intermediate tube 18. The other end of the corrugated pressure tube 19 is provided with an extrusion plate 25. The end of the extrusion plate 25 matches the side wall of the H-shaped steel beam 3. The extrusion plate 25 directly makes extrusion contact with the side wall of the H-shaped steel beam 3. The other end of the extrusion plate 25 is provided with a pressure sensor 23. The pressure sensor 23 is used to detect the pressure value at the end of the extrusion plate 25, that is, the pressure value between the extrusion plate 25 and the H-shaped steel beam 3.

[0058] Multiple sets of return springs 20 are evenly provided on one side of the vertical plate 17. The other end of the return spring 20 is fixedly connected to the side wall of the extrusion plate 25. The return spring 20 is located inside the corrugated pressure tube 19. The setting of the return spring 20 further realizes the elastic return performance of the extrusion plate 25. The end face of the extrusion plate 25 is provided with a friction surface. The setting of the friction surface not only improves the extrusion effect of the extrusion plate 25 on the H-beam 3, but also ensures the friction limiting effect of the extrusion plate 25 on the H-beam 3 by means of the friction surface, so as to avoid the H-beam 3 sliding on the side wall of the sliding plate 4 and reducing the limiting and clamping stability of the H-beam 3 during actual use.

[0059] The extrusion plate 25 has a three-way pipe 21 inside. One end of the three-way pipe 21 is connected to the corrugated pressure pipe 19 through a pneumatic one-way valve 22. The pneumatic one-way valve 22 has a preset air pressure value. The one-way flow direction of the pneumatic one-way valve 22 is from the end of the corrugated pressure pipe 19 to the end of the three-way pipe 21. When the air pressure inside the corrugated pressure pipe 19 reaches the preset air pressure value, the pneumatic one-way valve 22 opens, and the gas inside the corrugated pressure pipe 19 enters the three-way pipe 21. The other two ends of the three-way pipe 21 pass through both sides of the sliding plate 4. Both ends of the three-way pipe 21 are connected to protective airbags 24. When the gas inside the three-way pipe 21 flows in, the protective airbags 24 expand and elastically wrap and protect the side wall of the H-shaped steel beam 3, further improving the wrapping and protection performance of the H-shaped steel beam 3 under certain conditions.

[0060] The opening of the protective airbag 24 is fixedly connected to the inner wall of the three-way pipe 21. The protective airbag 24 matches the transverse direction of the H-shaped steel beam 3. This orientation improves the protective performance of the protective airbag 24 in wrapping and protecting the side wall of the H-shaped steel beam 3. The inside of the three-way pipe 21 contains hydrogen peroxide, and the outer surface of the hydrogen peroxide is equipped with a protective device. The inside of the protective airbag 24 contains potassium permanganate. When the pressure check valve 22 is opened, the gas inside the corrugated pressure pipe 19 enters the three-way pipe 21 and carries the hydrogen peroxide to the inside of the protective airbag 24. At the potassium permanganate end, hydrogen peroxide comes into direct contact with potassium permanganate and produces a large amount of oxygen. This oxygen, combined with the gas, directly increases the air pressure inside the protective airbag 24. The protective airbag 24 is elastic, and its outer surface matches the inner wall of the three-way pipe 21. When the volume of the protective airbag 24 increases, it expands to both sides, thus completely wrapping and protecting the side wall of the H-shaped steel beam 3, thereby preventing the H-shaped steel beam 3 from falling directly and causing significant damage and safety hazards to pedestrians or ground buildings.

[0061] In use, place the second horizontal plate 205 in the appropriate position according to the above process, and then... Figure 1By limiting the front, back, left, and right directions, it is easier to quickly and efficiently understand the solution. At the same time, the sliding plates 4 below are moved to a suitable distance from each other so that the distance between the two sliding plates 4 matches the width of the H-beam 3 and is slightly larger than the width of the H-beam 3. This setting can realize a fast and efficient splicing and installation process.

[0062] Then, the H-beam 3 is placed on top of the second horizontal plate 205. At the same time, the bottom of the H-beam 3 first presses against the top of the support rod 9. When the support rod 9 is pressed, it presses against the connecting spring 10 along the bottom groove 8 and moves downward. When the support rod 9 moves, it simultaneously squeezes the gas inside the bottom groove 8 into the connecting pipe 11 and enters the hose 12 along the connecting pipe 11. The gas inside the hose 12 enters the middle pipe 18 and finally enters the corrugated pressure pipe 19 along the middle pipe 18. The volume of the corrugated pressure pipe 19 increases and drives the end pressing plate 25 to move closer to the bottom sides of the H-beam 3 and finally press against the bottom sides of the H-beam 3. The pressure sensor 23 detects the pressure value. At this time, the electromagnet 14 is not energized and does not have magnetism. The magnetic push rod 16 moves to the initial position of the side groove 13 under the reverse pressure of the corrugated pressure pipe 19. The magnetic push rod 16 and the side groove 13 are sealed and matched.

[0063] Since the H-beam 3 is placed directly on top of the second horizontal plate 205, the placement position and accuracy of the H-beam 3 are not accurately detected. Therefore, the H-beam 3 is prone to displacement and reduced placement accuracy during actual placement. The pressure value detected by the pressure sensor 23 can be used to quickly and efficiently detect and correct the placement accuracy of the H-beam 3.

[0064] Specifically, when the pressure values ​​detected by the two sets of pressure sensors 23 on the same side are the same and greater than the preset pressure value, and the pressure values ​​detected by the pressure sensors 23 on the other side are the same and less than the preset pressure value, it indicates that the H-beam 3 is tilted in the left-right direction. That is, when the pressure values ​​detected by the two sets of pressure sensors 23 on the left are the same and greater than the preset pressure value, and the pressure values ​​detected by the two sets of pressure sensors 23 on the right are the same and less than the preset pressure value, but the pressure values ​​detected by the two sets of pressure sensors 23 on the left are greater than the pressure values ​​detected by the two sets of pressure sensors 23 on the right, it indicates that the placement of the H-beam 3 is biased to the left, and the position of the H-beam 3 needs to be readjusted. That is, by using the pressure difference detected by multiple sets of pressure sensors 23 on the left and right sides, the controller controls the pressure value detected by the pressure sensors 23. On the larger side, i.e., the left side groove 13, the electromagnet 14 is energized and the current increases. The electromagnet 14 applies a magnetic repulsive force to the magnetic push rod 16 and drives the magnetic push rod 16 to move the tension side spring 15 away from the electromagnet 14. The magnetic push rod 16 drives the extrusion plate 25 through the vertical plate 17 and the corrugated pressure tube 19 to apply extrusion force to the left side wall of the H-beam 3, thereby causing the H-beam 3 to move slowly to the right, further improving the fast and efficient calibration of the H-beam 3 in the left and right directions. When the pressure value detected by the pressure sensor 23 on the right side returns to the initial preset value, it means that the position of the H-beam 3 has met the requirements. Then the controller controls the electromagnet 14 on the left side to be de-energized, and all structures return to normal working state. If the pressure value detected by the pressure sensor 23 on the right side is greater than the preset pressure value, the same process as above can be performed.

[0065] Simultaneously, when the H-beam 3 is placed on top of the support rod 9 and tilts in the front-to-back direction, the pressure values ​​exerted by the H-beam 3 on the bottom support rod 9 are not equal, resulting in different downward distances for the support rod 9 along the bottom groove 8. Consequently, the amount of gas entering the corrugated pressure pipe 19 from inside the bottom groove 8 via the connecting pipe 11, hose 12, and intermediate pipe 18 is different. This leads to different pressure exerted by the corrugated pressure pipe 19 on the side wall of the H-beam 3 by the extrusion plate 25, resulting in different pressure values ​​detected by the pressure sensor 23. Specifically, when the H-beam 3 is actually positioned towards the rear end of the second horizontal plate 205, the extrusion force exerted by the H-beam 3 on the rear support rod 9 increases, while the extrusion force on the front support rod 9 decreases. The rear support rod 9 extrudes the connecting spring 10 and moves downward a greater distance inside the bottom groove 8, resulting in a greater amount of gas entering the corrugated pressure pipe 11, hose 12, and intermediate pipe 18. As the amount of gas entering the corrugated pressure pipe 19 through the hose 12 and intermediate pipe 18 increases, the pressure exerted by the corrugated pressure pipe 19 on the bottom sidewall of the H-beam 3 by the extrusion plate 25 increases. The pressure value detected by the rear pressure sensor 23 increases and exceeds the preset pressure value, while the pressure value detected by the front pressure sensor 23 decreases and falls below the preset pressure value. The position of the H-beam 3 is then adjusted accordingly, moving it towards the front. Consequently, the pressure value detected by the rear pressure sensor 23 decreases, and the pressure value detected by the front pressure sensor 23 increases. When the pressure values ​​detected by the pressure sensors 23 at both ends are equal, it indicates that the H-beam 3 is in a stable position. This process can effectively and accurately position the H-beam 3, further improving installation accuracy and stability.

[0066] Then, the first connector 1 is moved to the top of the H-beam 3, and the insertion sleeve 105 is inserted downwards and connected to the insertion rod 206. At this time, the first horizontal plate 106 moves downwards and continuously contacts the top of the H-beam 3. When the H-beam 3 is compressed, it simultaneously compresses multiple sets of support rods 9 downwards. The support rods 9 move downwards along the bottom groove 8 and reach the appropriate position. Then, the corresponding compression plate 25 compresses and fixes the two side walls of the bottom side of the H-beam 3. The pressure value detected by the pressure sensor 23 is further increased to the set installation pressure value. After the assembly is completed, the connecting hole 102 and the connecting hole 201 are spliced ​​together with the connecting bolt 6. When it is necessary to splice the connecting clamps of multiple floors, the through hole 104 and the splicing hole 204 are spliced ​​together with the alignment bolt 5, thereby completing the final splicing and installation process. The connecting clamps of the multiple floors of the suspension structure are then moved to the appropriate position and lifted.

[0067] When the connecting clamp vertically lifts the H-beam 3, if one side of the H-beam 3 tilts due to wind or other forces, it will cause instability in the internal structure. Specifically, when wind acts on the right side of the H-beam 3, the pressure exerted on the left-side pressing plate 25 by the wind increases, and the pressure values ​​detected by the two sets of pressure sensors 23 on the left increase. Correspondingly, the pressure exerted by the H-beam 3 on the right-side pressing plate 25 decreases, and the pressure values ​​detected by the two sets of pressure sensors 23 on the right decrease. Therefore, the controller controls the increase of the current flowing through the electromagnet 14 on the left side, and the magnetic repulsion force exerted by the electromagnet 14 on the magnetic push rod 16 increases. The magnetic push rod 16 stretches the side spring 15 inside the side groove 13 and moves closer to the end of the H-beam 3. The magnetic push rod 16 increases the compressive force applied to the extrusion plate 25 through the corrugated pressure tube 19. As a result, the supporting force applied by the extrusion plate 25 to the left side of the H-beam 3 increases, and the compressive force applied by the H-beam 3 to the right side of the extrusion plate 25 increases. The pressure value detected by the pressure sensor 23 on the right side increases back to the preset installation value. With the help of this supporting force, the left side of the H-beam 3 can be effectively supported and protected, avoiding the impact and shaking of the right side of the H-beam 3 by the wind force for a long time, thereby reducing the support stability and wind resistance of the H-beam 3.

[0068] Similarly, when the wind force on the left side applies a force to the left side of the H-beam 3, the controller controls the electromagnet 14 on the right side to increase the current, just as described above. The magnetic push rod 16 on the right side is moved outward by the magnetic repulsion force, and drives the pressing plate 25 on the right side to support the right side of the H-beam 3 and resist the wind force on the left side, further improving the stability of the H-beam 3 in actual use.

[0069] When the wind force balances the top or bottom of the H-beam 3, the first horizontal plate 106 and the second horizontal plate 205 limit and fix the H-beam 3, preventing it from moving between the first connecting piece 1 and the second connecting piece 2, thereby ensuring stability during the lifting process and the supporting and limiting effect on the H-beam 3.

[0070] However, due to the actual hoisting process, such as Figure 1As shown, when the wind force on the top front end of the H-beam 3 is greater than that on the top rear end, the H-beam 3 tilts downwards between the first horizontal plate 106 and the second horizontal plate 205. The pressure exerted by the bottom front end of the H-beam 3 on the two sets of support rods 9 increases, and the distance the support rods 9 travel downwards along the bottom groove 8 while pressing against the connecting spring 10 increases. The amount of gas entering the corrugated pressure pipe 19 from inside the bottom groove 8 via the connecting pipe 11, hose 12, and intermediate pipe 18 increases. The pressure exerted by the front end pressing plate 25 on both sides of the bottom front end of the H-beam 3 increases, and the pressure detected by the two sets of pressure sensors 23 increases. Simultaneously, since the H-beam 3 is suspended at the top of the first horizontal plate 106, it tilts at the top of the first horizontal plate 106. The pressure exerted by the H-beam 3 on the rear end support rods 9 decreases, and under the elastic force of the connecting spring 10, the support rods 9 move upwards. Therefore, the pressure exerted by the rear end pressing plate 25 on both sides of the rear end of the H-beam 3 decreases. As the pressure values ​​detected by the two sets of pressure sensors 23 at the rear decrease, in order to ensure that the H-beam 3 supports and protects against the pressure value at the top of the front end, the controller increases the energizing current of the two sets of electromagnets 14 at the front end. The pushing force applied by the electromagnets 14 to the magnetic push rod 16 increases, causing the tension spring 15 of the magnetic push rod 16 to move closer to the side wall end of the H-beam 3. The pressure value applied by the magnetic push rod 16 to the corrugated pressure tube 19 through the vertical plate 17 increases. At the same time, due to the position limitation of the extrusion plate 25, the gas inside the corrugated pressure tube 19 flows through the intermediate pipe 18, the hose 12 and the connecting pipe 11 to the bottom groove 8. The air pressure inside the bottom groove 8 increases, causing the support rod 9 at the front end to move upward. The support force applied by the support rod 9 at the front end to the bottom of the front end of the H-beam 3 increases, and the pressure values ​​detected by the pressure sensors 23 on both sides of the rear end increase again to the preset installation pressure value, further improving the support effect of the top of the front end of the H-beam 3 against the extrusion pressure, thereby effectively improving the stability and support effect of the H-beam 3.

[0071] When the wind force on the front bottom of the H-beam 3 is greater than that on the rear bottom, the H-beam 3 tilts upwards between the first horizontal plate 106 and the second horizontal plate 205. This reduces the compressive force exerted by the H-beam 3 on the front support rod 9, correspondingly reducing the compressive force exerted by the compression plates 25 on the sides of the H-beam 3. The pressure values ​​detected by the two sets of pressure sensors 23 at the front also decrease. However, under the support of the first horizontal plate 106, the H-beam 3 undergoes hinged rotation, increasing the compressive force exerted on the top of the rear support rod 9. The compressive force exerted by the two sets of compression plates 25 on the sides of the H-beam 3 also increases, further increasing the pressure values ​​detected by the two sets of pressure sensors 23 at the rear. During this process, the H-beam 3 remains tilted, therefore, further adjustments to its position and orientation are needed to improve its stability and support.

[0072] At this time, the controller increases the energizing current of the two sets of electromagnets 14 at the rear end, increasing the magnetic repulsion force exerted by the two sets of electromagnets 14 on the magnetic push rod 16. The two sets of magnetic push rods 16 at the rear end move the tension side spring 15 along the side groove 13 towards the two side walls closer to the H-shaped steel beam 3. The position of the rear end extrusion plate 25 remains unchanged, and the corresponding rear end corrugated pressure tube 19 is compressed. The gas inside the corrugated pressure tube 19 flows along the intermediate pipe 18, the hose 12, and the connecting pipe 11 to the rear end bottom groove 8. The air pressure inside the rear end bottom groove 8 increases, driving the rear end... As the support rod 9 moves upward, the supporting force exerted by the rear support rod 9 on the bottom of the rear end of the H-beam 3 increases. Correspondingly, the hinged limiting effect of the first horizontal plate 106 on the top of the H-beam 3 causes the front end of the H-beam 3 to rotate downward. The H-beam 3 limits and presses down on the wind force or load force at the bottom, thereby ensuring the stability and limiting of the bottom of the H-beam 3. At this time, the pressure value detected by the pressure sensors 23 on both sides of the front end increases again to the preset installation pressure value. Each structure repeats the above work and supports and limits it.

[0073] When the wind force or load force on the H-beam 3 returns to normal, the pressure values ​​detected by each pressure sensor 23 change accordingly. The controller then controls the current of the electromagnet 14 to decrease to the initial value, and the structure resumes normal operation and continues the subsequent support installation process.

[0074] During the actual lifting process, if the connecting clamp falls due to a hoisting error, it will cause the H-beam 3 to fall downwards simultaneously. When the second horizontal plate 205 contacts the ground, the H-beam 3 will continue to move downwards between the first horizontal plate 106 and the second horizontal plate 205 due to its own inertia. When the H-beam 3 is compressed, it will simultaneously compress the multiple sets of support rods 9 at the bottom. When the multiple sets of support rods 9 are compressed, they will compress the connecting spring 10 along the bottom groove 8 and move downwards. The gas inside the multiple sets of bottom grooves 8 will enter the corrugated pressure pipe 19 through the connecting pipe 11, the hose 12 and the intermediate pipe 18. The pressure applied by the corrugated pressure pipe 19 to the side wall of the H-beam 3 through the compression plate 25 will increase. The pressure values ​​detected by the multiple sets of pressure sensors 23 will increase and exceed the preset maximum pressure value. At this time, the controller will control the current of the multiple sets of electromagnets 14 to reach the maximum value. The magnetism of the electromagnets 14 will increase to the maximum value and the magnetic repulsion force applied to the magnetic push rod 16 will reach the maximum value. The magnetic push rod 16 will compress the corrugated pressure pipe 19. As the gas volume inside the bellows 19 increases and its volume decreases, the gas pressure inside the bellows 19 continuously increases and exceeds the preset gas pressure value set by the pressure check valve 22. The pressure check valve 22 then opens, and the gas inside the bellows 19 enters the three-way pipe 21 along the pressure check valve 22. This gas directly acts on the protective airbag 24, causing the volume of the protective airbag 24 to continuously increase. Simultaneously, the gas flow carries the hydrogen peroxide inside the three-way pipe 21 and the protective airbag. When the potassium permanganate inside the protective airbag 24 comes into contact with each other, a large amount of oxygen is produced after the chemical reaction. This oxygen directly acts on the inside of the protective airbag 24, causing the volume of the protective airbag 24 to continuously increase. The protective airbag 24 expands along both ends of the three-way tube 21, and the protective airbag 24 directly elastically wraps and protects the two side walls of the H-shaped steel beam 3, effectively preventing the H-shaped steel beam 3 from falling directly to the ground and causing damage to people on the road or the ground safety, and further improving the safety and stability of the H-shaped steel beam 3.

[0075] This device effectively improves installation accuracy, positioning precision, and installation efficiency when installing H-beams 3, effectively meeting actual production and processing needs and ensuring the clamping and fixing effect of the connecting clamps on H-beams 3. Simultaneously, it provides reverse support protection against wind or load forces on H-beams 3, further ensuring their stability and support, thereby improving safety and stability. Furthermore, when the connecting clamps fall and cause H-beams 3 to fall simultaneously, the protective airbag 24 provides all-around, comprehensive protection for H-beams 3, further enhancing safety and protection in actual use and preventing significant safety and economic losses.
