Description

Technical Field

[0001] The present invention relates to the technical field of building steel, and in particular to a connection base for a load-bearing column of a building steel structure and a connection method. Background Art

[0002] Steel structure, a structure mainly made of steel, is one of the main types of building structures. The characteristics of steel are high strength, light weight, good overall rigidity and strong deformation capacity. Therefore, it is particularly suitable for building large-span, ultra-high and ultra-heavy buildings. The material has good plasticity and toughness, can have large deformation, and can withstand dynamic loads well. The construction period is short. It has a high degree of industrialization and can be produced in a highly mechanized and specialized manner.

[0003] When existing construction steel is used to build factories or other buildings, the I-beams are lifted and then manually adjusted to connect with the concrete. The I-beams need to be perpendicular to the ground to fix them. The angle is difficult to adjust, which increases the difficulty of construction and reduces the construction speed. The unstable I-beams are manually supported, and the I-beams shake, which can easily cause the I-beams to injure workers, increasing the risk. At the same time, after the I-beams are built, the foundation is prone to changes over a long period of time due to the influence of groundwater or other environmental factors. After the factory building is built, it is difficult to detect the pressure on the foundation, and the safety of the factory cannot be predicted in advance. Summary of the Invention

[0004] When using existing I-beams to build factories or other buildings, the angle is difficult to adjust, which increases the difficulty of construction and reduces the construction speed. The I-beams shake, which increases the risk. It is difficult to detect the pressure on the foundation, and it is impossible to predict safety problems caused by foundation problems in the factory in advance. The present invention proposes a connection base and connection method for the load-bearing columns of a building steel structure.

[0005] The present invention provides a connection base and connection method for a load-bearing column of a building steel structure, comprising a fixed base and an I-steel, a connection base body, a connection device, an anti-dumping device and a detection device;

[0009] The detection device includes a displacement sensor for detection. The detection device is located inside the connecting seat, and the displacement sensor detects the ground under the I-beam.

[0010] Preferably, one end of the rotating base is rotatably connected to one end of the connecting base body, and a device cavity is opened inside the connecting base body, and a limiting sleeve is fixedly installed on the inner wall of the device cavity. The inner wall of the limiting sleeve is threadedly connected with a fixing bolt, and the outer surface of the fixing bolt is threadedly connected to the inner part of the connecting rod of the rotating base. The fixing bolt realizes a fixing action between the rotating base and the limiting sleeve, and one end of the I-beam is fixedly installed on the upper end of the rotating base by a bolt.

[0011] Through the above technical solution, the rotating base can be deflected on the connecting base body, which is convenient for the installation of the I-beam. It is only necessary to use a forklift to lift the I-beam parallel to the ground and insert one end into the inner surface of the rotating base. The rotating base and the I-beam are fixed with bolts. The installation of the I-beam load-bearing column does not require lifting to adjust the angle.

[0012] Preferably, the support mechanism also includes a support hydraulic cylinder, one end of the support hydraulic cylinder is hinged to the upper surface of the connecting seat body through a pin, one end of the piston rod of the support hydraulic cylinder is hinged to the lower surface of the rotating base through a pin, and a pulling frame is fixedly installed on one side of the rotating base.

[0013] Through the above technical solution, the supporting hydraulic cylinder can automatically drive the rotating base to deflect, and at the same time can play a supporting role after the I-beam is installed to prevent the I-beam from tipping over during the deflection and straightening process. After the steel wire rope is installed on the pulling frame, the steel wire rope is driven by the trolley to pull, so that the rotating base can drive the installed I-beam to deflect after the deflection, and with the push of the supporting hydraulic cylinder, the I-beam can be transformed from a state parallel to the ground to a state perpendicular to the ground.

[0014] Preferably, the upper surface of the rotating base is hinged with a connecting rod through a pin shaft, and the two ends of the connecting rod are respectively hinged to the lower end of the scissors frame component through a pin shaft, and the lower end of the scissors frame component is rotatably connected to a roller, and the outer surface of the roller is slidably connected to the upper surface of the rotating base, and the two sides of the scissors frame component are fixed to the outer surface of the I-beam by bolts.

[0015] According to the above technical solution, after the scissors frame components are unfolded, the hinges on both sides of the scissors frame components are fixed to the I-beam by bolts, which can increase the support area of ​​the I-beam and enhance the stability of the I-beam after installation.

[0016] Preferably, the limiting mechanism also includes a ratchet, the inner walls of the two ratchets are respectively fixedly mounted on the two ends of the connecting rod of the rotating base, and connecting frames are fixedly mounted on both sides of the upper surface of the connecting seat body. One end of the pawl is hinged to the outer surface of the connecting frame through a pin shaft, and a tension spring that provides elastic force to the pawl is fixedly mounted on the outer side surface of the connecting frame, and one end of the pawl is slidably inserted into the outer surface of the tooth groove of the ratchet.

[0017] Through the above technical solution, the pawl is inserted into the tooth groove of the ratchet to limit the ratchet so that the ratchet can only rotate in one direction, preventing the I-beam from tipping over during the return process and increasing the supporting force of the I-beam during the return process.

[0018] Preferably, the release mechanism further includes a fixed sleeve, one end of the fixed sleeve is fixedly installed on the lower surface of the connecting frame, a movable sleeve is slidably inserted into the inner wall of the fixed sleeve, a sliding groove is provided on the outer side surface of the fixed sleeve, a movable block is fixedly installed on the outer surface of the movable sleeve, one end of the movable block is slidably connected to the inner wall of the sliding groove, a return spring is fixedly installed on the inner wall of the movable sleeve, the other end of the return spring is fixedly installed on the lower surface of the connecting frame, and a ball is slidably inserted into the inner wall of the movable sleeve.

[0019] Through the above technical solution, after the movable sleeve is driven upward by the movable block, the two relative balls can move in opposite directions along the contour of the push rod. The gap between the movable sleeve and the fixed sleeve can facilitate the outward movement of the balls while playing a limiting role.

[0020] Preferably, the outer surface of the push rod is slidably connected with the outer surface of the ball and then penetrates the upper surface of the bottom plate of the connecting frame and contacts the lower surface of the pawl.

[0021] Through the above technical solution, the ball fixes the push rod through the groove on the push rod, and the ball is inserted into the groove of the push rod to fix the push rod. After the push rod lifts the pawl, it leaves the connection with the ratchet and contacts the limit of the ratchet, so that the rotating base can be deflected and installed with the I-beam.

[0022] Preferably, the detection device also includes a detection channel, which is opened inside the connecting seat body, and a detection door is fixedly installed on the outer side of the device cavity. A screw is installed on the inner wall of the detection channel through a bearing, and the outer surface of the screw is threadedly connected to a support plate. The outer surface of the support plate is slidably plugged into the inner wall of the detection channel to realize the limiting action of the support plate.

[0023] Through the above technical solution, after the detection door is opened, the screw rod can be rotated to allow the probe of the displacement sensor to be inserted into the ground below the fixed base through the detection channel to detect the ground below. The rotation of the screw rod can facilitate the lifting of the displacement sensor and pressure sensor for inspection at any time.

[0024] Preferably, the outer surface of the displacement sensor is fixedly mounted on the upper surface of the support plate, a pressure sensor is fixedly mounted on the upper surface of the support plate, and a settlement plate is hinged to the lower surface of the support plate via a spherical hinge.

[0025] Through the above technical solution, the interior of the ground below the I-beam after installation is detected by displacement sensors and pressure sensors to prevent the I-beam from being installed for a long time. The ground will not sink due to external factors such as time and groundwater, which will affect the I-beam's load-bearing columns. Through detection, preventive work can be carried out at any time to reduce losses.

[0026] Preferably, S1: when a factory building needs to be built, after the right-angled insertion of the fixed base is inserted into the ground, concrete is poured on the ground, and the fixed base is buried under the concrete. At the same time, the center of the fixed base is protected to prevent concrete from entering, so that the subsequent detection device can be inserted into the ground. The bolts on the upper surface of the fixed base can be located above the concrete, and the through holes on the connecting base are inserted into the bolts on the fixed base, and the connecting base and the fixed base are fixed by bolts and nuts;

[0027] S2: Push the push rod upward, so that one end of the push rod drives the moving sleeve to move while the ball is squeezed and moved to both sides. The first groove of the push rod leaves the ball, and the push rod rises to lift the pawl and deflect it. When the ball encounters the second groove of the push rod, it can be reset while the moving sleeve moves downward under the elastic force of the reset spring. The ball is inserted into the groove of the push rod to fix the push rod. After the pawl leaves the ratchet, the rotation of the ratchet is unrestricted;

[0028] S3: The supporting hydraulic cylinder on the connecting base is started, driving the rotating base to deflect on the connecting base. After the state is transformed from perpendicular to the ground to parallel to the ground, the I-beam to be installed is forked by a forklift and kept parallel to the ground. After one end of the I-beam is inserted into the front and back ends of the rotating base, the rotating base and one end of the I-beam are fixed with bolts. After that, the scissor frame component is pulled apart, and the scissor frame component drives the connecting rod to deflect. At the same time, the roller rolls on the outer surface of the rotating base. After the hinges at both ends of the scissor frame component are aligned with the bolt holes on the I-beam, the long bolts are passed through the hinges of the scissor frame component and the I-beam to fix the scissor frame component to the I-beam.

[0029] S4: The movable sleeve is driven upward by the movable block, so that the ball moves outward, releasing the limit on the push rod, and the push rod is moved downward, so that the push rod leaves the pawl. The pawl is reset under the elastic force of the tension spring and is inserted into the outer surface of the ratchet again. When the ball encounters the first groove on the push rod, it can fix the push rod again;

[0030] S5: Fix one end of the wire rope to one end of the pulling frame on the rotating base. In order to stably pull the I-beam to lift it, tie a wire rope to the long bolt that fixes the scissor frame component and the I-beam. Pull the two wire ropes by moving the trolley. The wire rope pulls the rotating base to rotate, and at the same time, the piston rod of the supporting hydraulic cylinder retracts, which can deflect the rotating base and the I-beam back to the center. The pawl prevents the ratchet from rotating. After the I-beam is perpendicular to the ground, insert the fixing bolt into the limit sleeve to fix the rotating base and the connecting base body. The rotating base cannot rotate;

[0031] S6: Open the detection door and rotate the screw rod to move the support plate downward in the detection channel. After the settlement plate contacts the ground inside the foundation, the displacement sensor detects the offset of the settlement plate. The settlement of the foundation is detected by the offset change of the settlement plate. After the pressure sensor gets the probe inserted into the foundation, the pressure applied by the foundation is detected. When the foundation settlement is loose, the pressure is lower than the set threshold, and the settlement change of the foundation can be detected.

[0032] The beneficial effects of the present invention are:

[0033] 1. By setting a connecting device, the I-beam that needs to be fixed can be fixed, and it is convenient to build the I-beam. Through the deflection of the rotating base, after the I-beam is connected to the rotating base in parallel with the ground, the I-beam can be transformed from a state parallel to the ground to a state perpendicular to the ground through the deflection of the rotating base, reducing manual adjustment of the angle of the I-beam and reducing the danger of construction. Through the stretching of the scissors frame component, it can be fixed to the lower end of the I-beam, increasing the stability of the I-beam, thereby speeding up the construction speed, solving the technical problems of the existing I-beam being difficult to adjust the angle when building a factory building or other buildings, increasing the difficulty of construction, reducing the construction speed, and shaking the I-beam, which increases the danger.

[0034] 2. By setting up an anti-dumping device, the I-beam can be prevented from dumping during the return process. Through the cooperation of the ratchet and the pawl, the rotating base can be deflected in only one direction. Through the support of the hydraulic cylinder, the stability of the rotating base during deflection can be increased, and the I-beam can be supported. The pawl can be deflected by the push rod without affecting the deflection of the rotating base before the installation of the I-beam, so that the deflection of the I-beam can be more stable, reducing the danger of the installation of the I-beam, and solving the problem of the existing I-beam being difficult to adjust the angle when building a factory or other building, which increases the difficulty of construction and reduces the construction speed. At the same time, the shaking of the I-beam increases the danger.

[0035] 3. By setting up a detection device, the foundation after the I-beam is installed can be detected. By using a pressure sensor and a displacement sensor to detect the foundation under the I-beam, changes in the foundation can be prevented in advance, preventive measures can be taken in advance, and property losses can be reduced.

[0054] In order to provide stable support for the I-beam 11, a connecting rod 32 is hinged on the upper surface of the rotating base 2 through a pin, and the two ends of the connecting rod 32 are respectively hinged to the lower end of the scissors frame component 33 through a pin. The scissors frame component 33 is composed of multiple groups of centrally hinged scissors frames hinged at both ends, and can be extended and retracted. The scissors frame component 33 is extended and retracted so that the two ends of the scissors frame component 33 can be connected to the bolt holes on the I-beam 11 accordingly. In order to facilitate the stretching of the scissors frame component 33, a roller 34 is rotatably connected to the lower end of the scissors frame component 33, and the outer surface of the roller 34 is slidably connected to the upper surface of the rotating base 2. In order to fix the I-beam 11, the two sides of the scissors frame component 33 are fixed to the outer surface of the I-beam 11 by bolts.

[0055] like Figure 2-4 and Figure 8-9As shown, the anti-dumping device is located on the outer surface of the rotating base 2 and limits the rotating base 2. The anti-dumping device includes a limiting mechanism and a releasing mechanism. The limiting mechanism includes a pawl 42 for limiting, and the pawl 42 limits the rotation of the rotating base 2. The releasing mechanism includes a push rod 56 for pushing the pawl 42 to deflect, and the push rod 56 pushes the pawl 42 to mechanically deflect.

[0056] The limiting mechanism is installed on the outer side surface of the rotating base 2. In order to limit the rotating base 2, the ratchet 4 is fixedly installed on both sides of the rotating base 2. In order to fix the pawl 42, a connecting frame 41 is fixedly installed on both sides of the upper surface of the connecting base body 12. One end of the pawl 42 is hinged to the outer surface of the connecting frame 41 through a pin. In order to facilitate the resetting of the pawl 42, a tension spring 43 that provides elastic force for the pawl 42 is fixedly installed on the outer side surface of the connecting frame 41. One end of the pawl 42 is slidably inserted into the outer surface of the tooth groove of the ratchet 4.

[0057] The releasing mechanism is installed on the outer surface of the connecting frame 41. In order to promote the movement of the pawl 42, a fixed sleeve 5 is fixedly installed on the lower surface of the connecting frame 41. In order to fix the push rod 56, a movable sleeve 51 is slidably inserted into the inner wall of the fixed sleeve 5. In order to drive the movable sleeve 51 to move, a sliding groove 52 is provided on the outer side surface of the fixed sleeve 5. A movable block 53 is fixedly installed on the outer surface of the movable sleeve 51. One end of the movable block 53 is slidably connected to the inner wall of the sliding groove 52. In order to facilitate the resetting of the movable sleeve 51, a reset spring 54 is fixedly installed on the inner wall of the movable sleeve 51. The other end of the reset spring 54 is fixedly installed on the lower surface of the connecting frame 41. In order to lock the push rod 56, a ball 55 is slidably inserted into the inner wall of the movable sleeve 51.

[0058] In order to push the pawl 42 , the outer surface of the push rod 56 is slidably inserted into the outer surface of the ball 55 , penetrates the upper surface of the bottom plate of the rotating base 2 , and contacts the lower surface of the pawl 42 .

[0059] like Figure 10-11 As shown, the detection device includes a displacement sensor 64 for detection. The detection device is located inside the connecting seat 12, and the displacement sensor 64 detects the ground under the I-beam 11.

[0060] The detection device is installed in the internal position of the device cavity 21. In order to push the displacement sensor 64 to move and be inserted into the foundation, a detection channel 6 is opened inside the connecting seat 12. In order to facilitate the inspection of the displacement sensor 64, a detection door 61 is fixedly installed on the outer side of the device cavity 21. In order to adjust the geological detector, a screw rod 62 is installed on the inner wall of the detection channel 6 through a bearing. In order to drive the displacement sensor 64 to rise and fall, a support plate 63 is threadedly connected to the outer surface of the screw rod 62. The outer surface of the support plate 63 is slidably inserted into the inner wall of the detection channel 6 to realize the limiting action of the support plate 63.

[0061] In order to detect the geological conditions of the foundation under the I-beam 11, the outer surface of the displacement sensor 64 is fixedly installed on the upper surface of the support plate 63. The displacement sensor 64 detects the deflection of the settlement plate 66. The upper surface of the support plate 63 is fixedly installed with a pressure sensor 65. The pressure sensor 65 monitors the pressure of the foundation. The lower surface of the support plate 63 is hinged with the settlement plate 66 through a spherical hinge. The settlement plate 66 can be deflected at any angle.

[0062] S1: When a factory building needs to be built, the right-angled insertion of the fixed base 1 is first inserted into the ground, and concrete is poured on the ground to bury the fixed base 1 under the concrete. At the same time, the center of the fixed base 1 is protected to prevent concrete from entering, so that the subsequent detection device can be inserted into the ground. The bolts on the upper surface of the fixed base 1 can be located above the concrete, and the through holes on the connecting base 12 are inserted into the bolts on the fixed base 1. The connecting base and the fixed base 1 are fixed by bolts and nuts;

[0063] S2: Push the push rod 56 to move upward, so that one end of the push rod 56 drives the movable sleeve 51 to move while the ball 55 is squeezed and moved to both sides. The first groove of the push rod 56 leaves the ball 55. The push rod 56 rises and pushes up the pawl 42 to deflect. When the ball 55 encounters the second groove of the push rod 56, the movable sleeve 51 moves downward and the ball 55 is reset under the elastic force of the reset spring 54. The ball 55 is inserted into the groove of the push rod 56 to fix the push rod 56. After the pawl 42 leaves the ratchet 4, the rotation of the ratchet 4 is unrestricted.

[0064] S3: The supporting hydraulic cylinder 3 on the connecting base body 12 is started, driving the rotating base 2 to deflect on the connecting base body 12. After the state is transformed from perpendicular to the ground to parallel to the ground, the I-beam 11 to be installed is forked by a forklift and kept parallel to the ground. After one end of the I-beam 11 is inserted into the two ends of the rotating base 2, the rotating base 2 and one end of the I-beam 11 are fixed by bolts. After that, the scissors frame component 33 is pulled apart, and the scissors frame component 33 drives the connecting rod 32 to deflect. At the same time, the roller 34 rolls on the outer surface of the rotating base 2. After the hinges at both ends of the scissors frame component 33 are aligned with the bolt holes on the I-beam 11, the long bolts are passed through the hinges of the scissors frame component 33 and the I-beam 11 to fix the scissors frame component 33 to the I-beam 11;

[0065] S4: The movable sleeve 51 is moved upward by the movable block 53, so that the ball 55 moves outward, releasing the limit on the push rod 56, and moving the push rod 56 downward. The push rod 56 leaves the pawl 42, and the pawl 42 is reset under the elastic force of the tension spring 43 and is again inserted into the outer surface of the ratchet 4. When the ball 55 encounters the first groove on the push rod 56, it can fix the push rod 56 again.

[0066] S5: Fix one end of the steel wire rope to one end of the pulling frame 31 on the rotating base 2. In order to stably pull the I-beam 11 to lift it, a steel wire rope can be tied to the long bolts fixing the scissors frame component 33 and the I-beam 11. The two steel wire ropes are pulled by the mobile trolley. The steel wire rope pulls the rotating base 2 to rotate, and at the same time, the piston rod of the supporting hydraulic cylinder 3 retracts, which can deflect the rotating base 2 and the I-beam 11 back to the center. The pawl 42 prevents the ratchet 4 from rotating. After the I-beam 11 is vertical to the ground, the fixing bolt 23 is inserted into the limiting sleeve 22 to fix the rotating base 2 and the connecting base body 12. The rotating base 2 cannot rotate.

[0067] S6: Open the detection door 61 and rotate the screw 62 to move the support plate 63 downward in the detection channel 6. After the settlement plate 66 contacts the ground inside the foundation, the displacement sensor 64 detects the offset of the settlement plate 66. The settlement of the foundation is detected by the offset change of the settlement plate 66. After the pressure sensor 65 gets the probe inserted into the foundation, the pressure applied by the foundation is detected. When the foundation settlement is loose, the pressure is lower than the set threshold, and the settlement change of the foundation can be detected.

[0068] Working principle: When it is necessary to build a factory building, the right-angled insertion of the fixed base 1 is first seen into the ground, and concrete is poured on the ground to bury the fixed base 1 under the concrete. At the same time, the center of the fixed base 1 is protected to prevent concrete from entering. A detection channel 6 is excavated at the center of the fixed base 1, and the bottom wall of the channel is kept flat to facilitate the placement of the settlement plate 66 and the insertion of subsequent detection devices into the ground. The bolts on the upper surface of the fixed base 1 can be located above the concrete, and the through holes on the connecting base 12 are inserted into the bolts on the fixed base 1. The connecting base and the fixed base 1 are fixed by bolts and nuts.

[0069] The push rod 56 is pushed upward, so that one end of the push rod 56 drives the movable sleeve 51 in the fixed sleeve 5 to move, and at the same time the ball 55 is squeezed and moved to both sides. The first groove of the push rod 56 leaves the ball 55. After the push rod 56 rises and passes through the connecting frame 41, it pushes up the pawl 42 and deflects it. When the ball 55 encounters the second groove of the push rod 56, it can be reset while the movable sleeve 51 moves downward under the elastic force of the reset spring 54. The ball 55 is inserted into the groove of the push rod 56 to fix the push rod 56. After the pawl 42 leaves the ratchet 4, the rotation of the ratchet 4 is unrestricted.

[0070] When the supporting hydraulic cylinder 3 on the connecting seat body 12 is started, the rotating base 2 is driven to deflect on the connecting seat body 12. After the state perpendicular to the ground is transformed into a state parallel to the ground, the I-beam 11 to be installed is forked by a forklift and kept parallel to the ground. After one end of the I-beam 11 is inserted into the two ends of the rotating base 2, the rotating base 2 and one end of the I-beam 11 are fixed by bolts. After that, the scissors frame component 33 is pulled apart, and the scissors frame drives the connecting rod 32 to deflect. At the same time, the roller 34 rolls relatively on the outer surface of the rotating base 2. After the hinged ends of the scissors frame component 33 are aligned with the bolt holes on the I-beam 11, the long bolts are passed through the hinged ends of the scissors frame component 33 and the I-beam 11 to fix the scissors frame component 33 to the I-beam 11.

[0071] The movable sleeve 51 is moved upward by the movable block 53, so that the ball 55 moves outward, releasing the limit on the push rod 56, and moving the push rod 56 downward. The push rod 56 leaves the pawl 42, and the pawl 42 is reset under the elastic force of the tension spring 43 and is again inserted into the outer surface of the ratchet 4. When the ball 55 encounters the first groove on the push rod 56, it can fix the push rod 56 again.

[0072] One end of the steel wire rope is fixed to one end of the pulling frame 31 on the rotating base 2. In order to stably pull the I-beam 11 to lift it, a steel wire rope can be tied to the long bolts fixing the scissors frame component 33 and the I-beam 11. The two steel wire ropes are pulled by the mobile trolley. The steel wire rope pulls the rotating base 2 to rotate, and at the same time, the piston rod of the supporting hydraulic cylinder 3 is retracted, which can deflect the rotating base 2 and the I-beam 11 back to the center. The pawl 42 prevents the ratchet 4 from rotating. After the I-beam 11 is vertical to the ground, the fixing bolt 23 is inserted into the limiting sleeve 22 to fix the rotating base 2 and the connecting base body 12, and the rotating base 2 cannot rotate.

[0073] Open the detection door 61 and rotate the screw rod 62 to move the support plate 63 downward in the detection channel 6. After the settlement plate 66 contacts the ground inside the foundation, the displacement sensor 64 detects the offset of the settlement plate 66. The settlement of the foundation is detected by the offset change of the settlement plate 66. After the pressure sensor 65 gets the probe inserted into the foundation, the pressure applied by the foundation is detected. When the foundation settlement is loose, the settlement change of the foundation can be detected after the pressure is lower than the set threshold.
