Description

Technical Field

[0001] The invention relates to the technical field of steel frame structure reinforcement, in particular to a steel frame structure reinforcement device for internal floor addition and reconstruction of an old factory building. Background Art

[0002] Steel structure is one of the mainstream choices for factory construction. Steel structure has high strength and light weight, and can easily realize large-span design. It is suitable for factories that require open space and does not require too many columns inside, which facilitates equipment layout and production process planning.

[0003] In order to extend the service life of a building, improve structural safety, or perform functional upgrades, such as when adding floors to an old factory building, the original steel frame structure needs to be reinforced. When reinforcing a steel structure factory building with a ridge, a triangular reinforcement plate is generally welded under the ridge steel beam to improve the structural strength of the ridge steel beam connection point. An I-shaped steel frame is generally used as a ridge steel beam. When welding the reinforcement plate, the reinforcement plate and the worker are lifted to the steel beam through a lifting platform. The worker then aligns the reinforcement plate with the bottom of the steel beam connection point, and then the worker holds a welding gun to weld the reinforcement plate to the steel beam. Since there are multiple steel beams inside the factory building, the steel beams and reinforcement plates are welded by manual welding, and the welding efficiency is low. In addition, during the welding process, the reinforcement plate is sometimes required to be lifted and supported manually, which increases the burden on the workers and affects the efficiency of the renovation and reinforcement of the old factory building.

[0029] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described below, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] See also Figure 1 - Figure 10 A steel frame structure reinforcement device for adding floors to an old factory building includes a hanging unit 1. The hanging unit 1 includes a concave-shaped hanging bracket 11 for hanging on an I-shaped steel beam 5 and rubber wheels 12 rotatably installed on the rear side of the top horizontal section of the hanging bracket 11 and symmetrically distributed on the left and right. A cross frame 13 is installed on the bottom horizontal section of the hanging bracket 11.

[0031] The positioning unit 2 includes a support base 21 movably mounted on the top of the cross frame 13, and a clamping plate 1 22 and a clamping plate 24 are installed on the support base 21 for centering the reinforcing plate 6 in the front, back, left and right directions. A lifting component 26 is installed between the bottom of the support base 21 and the top of the cross frame 13 to drive the support base 21 to move up and down, and a welding unit 3 is installed for welding the I-shaped steel beam 5 and the reinforcing plate 6.

[0032] The guiding unit 4 includes a fixed block 41 fixedly connected to the bottom center of the top horizontal section of the hanger 11. The front side of the bottom end of the fixed block 41 is rotatably connected to a guide frame 42 for guiding the welding unit 3 to move along the welding trajectory of the I-shaped steel beam 5 and the reinforcing plate 6 and is symmetrically distributed on the left and right. A slide groove 43 is provided on the guide frame 42. A slide rod 44 is rotatably installed on the front side of the second splint 24. When the second splint 24 clamps the left and right ends of the reinforcing plate 6, the axis of the slide rod 44 is aligned front and back with the lowest point of the left and right oblique sides of the reinforcing plate 6, and the slide rod 44 is slidably installed inside the slide groove 43.

[0033] During specific use, first place the reinforcing plate 6 on the support seat 21, use the clamping plate 22 to clamp the reinforcing plate 6 front and back, and then hang the left and right rubber wheels 12 on the bottom edges of the left and right I-shaped steel beams 5 respectively. The rubber wheel 12 has a certain elasticity and can adaptively deform according to the wall thickness or the angle of the top of the I-shaped steel beam 5. Align the fixing block 41 with the joint of the left and right I-shaped steel beams 5. The bottom end of the fixing block 41 is located directly above the highest point of the bottom edge of the I-shaped steel beam 5. The reinforcing plate 6 is located below the I-shaped steel beam 5 and does not contact the I-shaped steel beam 5.

[0034] When the second clamping plate 24 is clamped on the left and right ends of the reinforcing plate 6, the sliding rod 44 is aligned with the lowest points of the left and right oblique sides of the reinforcing plate 6, and the lifting assembly 26 pushes the support seat 21 to move upward, so that the left and right oblique sides of the reinforcing plate 6 respectively conflict with the bottom of the corresponding I-shaped steel beam 5. Then the lifting assembly 26 continues to give the support seat 21 an upward thrust. Because the reinforcing plate 6 is blocked by the I-shaped steel beam 5 and cannot continue to move upward, the lifting assembly 26 will push the hanger 11 to move downward, causing the rubber wheel 12 to be compressed and deformed, so that the hanger 11 drives the fixing block 41 to move downward until the bottom end of the fixing block 41 is aligned with the highest point of the bottom edge of the I-shaped steel beam 5 front and back. At this time, the axis of the top end of the guide frame 42 is aligned with the highest point of the bottom edge of the I-shaped steel beam 5 front and back, so that the guide frame 42 remains parallel to the bottom edge of the I-shaped steel beam 5.

[0035] Afterwards, the welding unit 3 moves from left to right to weld the I-shaped steel beam 5 and the reinforcing plate 6. During the movement, the welding unit 3 is guided by the guide frame 42, so that the welding unit 3 can move along the trajectory of the weld of the I-shaped steel beam 5 and the reinforcing plate 6, automatically performing welding and improving the welding efficiency.

[0036] After welding is completed, the lifting assembly 26 drives the support seat 21 to move downward, so that the clamping plate 1 22 and the clamping plate 2 24 release the clamping of the reinforcing plate 6, and finally the hanger 11 is moved forward and removed from the I-shaped steel beam 5.

[0037] See also Figure 1 - Figure 2 A moving assembly 15 for driving the welding unit 3 to move left and right is also installed on the horizontal frame 13. The moving assembly 15 includes a screw 151 rotatably installed inside the horizontal frame 13. A driving motor 152 for driving the screw 151 to rotate is fixedly installed at the left end of the horizontal frame 13. The right end of the output shaft of the driving motor 152 is fixedly connected to the left end of the screw 151. The external thread of the screw 151 is connected to a slider 153. The slider 153 is installed inside the screw 151 for sliding left and right. The welding unit 3 is installed on the slider 153.

[0038] During specific use, the motor 152 is driven to drive the screw 151 to rotate, and the screw 151 is used to drive the slider 153 to move left and right, so that the slider 153 drives the welding unit 3 to move left and right, so that the welding unit 3 can move left and right to weld the weld between the I-shaped steel beam 5 and the reinforcement plate 6.

[0039] See also Figure 1 and Figure 3The support seat 21 is concave in shape, and the splint 22 is installed on the horizontal section of the support seat 21 for sliding back and forth and is symmetrically distributed front and back. The vertical section of the support seat 21 is installed with an elastic telescopic rod 23 for pushing the splint 22 to move toward the center of the support seat 21 and is symmetrically distributed left and right. The top of the splint 22 is inclined toward the direction away from the center of the support seat 21.

[0040] During specific use, when the reinforcing plate 6 is to be placed on the support seat 21, the reinforcing plate 6 is pressed down from top to bottom and placed between the front and rear clamps 22, and the elastic telescopic rod 23 is used to move the clamp 22 toward the center of the support seat 21, so that the clamp 22 can be clamped on the front and rear sides of the reinforcing plate 6, and the reinforcing plate 6 is clamped front and back. This is beneficial for the subsequent pressing of the reinforcing plate 6 and the I-shaped steel beam 5 together, so that the reinforcing plate 6 can remain centered front and back, thereby improving the stability of the support and the reinforcement effect; by tilting the top of the clamp 22, it is convenient to press the reinforcing plate 6 between the clamps 22.

[0041] See also Figure 3 and Figure 4 The support seat 21 is also equipped with a centering component 25 for driving the left and right splints 24 to move in opposite directions. The centering component 25 includes a gear 251 rotatably installed inside the support seat 21. The front and rear sides of the gear 251 are meshed with racks 252. The rack 252 slides left and right through the support seat 21. The left end of the front rack 252 is fixedly connected to the left splint 24, and the right end of the rear rack 252 is fixedly connected to the right splint 24. The side of the splint 24 close to the support seat 21 is also fixedly connected to a guide bar 253. The guide bar 253 slides through the support seat 21 at the end away from the splint 24 and is fixedly connected to the corresponding rack 252 through the connecting block 254.

[0042] During specific use, the gear 251 is rotated to drive the racks 252 on the front and rear sides to move synchronously in opposite directions, and the racks 252 are used to drive the left and right clamps 24 to approach each other, so that the clamps 24 clamp the reinforcing plate 6 left and right. When the reinforcing plate 6 and the I-shaped steel beam 5 are subsequently pressed together, the top of the reinforcing plate 6 is aligned with the joints of the left and right I-shaped steel beams 5, thereby improving the accuracy of the docking between the reinforcing plate 6 and the I-shaped steel beam 5.

[0043] When the rack 252 drives the second splint 24 to move, the guide bar 253 slides left and right along the support seat 21, and the guide bar 253 is used to support the second splint 24 to improve the stability of the movement of the second splint 24. The rack 252 and the guide bar 253 are connected together by the connecting block 254, which can improve the strength of the rack 252 and the guide bar 253 and prevent deformation.

[0044] See also Figure 2 、 Figure 5 and Figure 6 The lifting assembly 26 includes a fixed sleeve 261 fixedly connected to the bottom of the support seat 21, and a movable column 262 is installed on the bottom of the fixed sleeve 261 for sliding up and down. The bottom end of the movable column 262 is fixedly connected to the top of the cross frame 13, and a threaded rod 263 is installed inside the fixed sleeve 261 for rotation. The bottom end of the threaded rod 263 is threadedly connected to the movable column 262. A guide telescopic rod 264 symmetrically distributed about the fixed sleeve 261 is also fixedly connected between the support seat 21 and the cross frame 13. The top of the threaded rod 263 rotates and passes through the top of the gear 251. A driving motor 265 for driving the threaded rod 263 to rotate is installed inside the support seat 21, and a follower assembly is installed between the gear 251 and the fixed sleeve 261.

[0045] During specific use, the threaded rod 1 263 is driven to rotate by driving motor 265, and the threaded rod 1 263 is used to drive the movable column 262 to move downward, and the movable column 262 is used to increase the distance between the support seat 21 and the cross frame 13, so that the support seat 21 can drive the reinforcement plate 6 to move upward and gradually approach the I-shaped steel beam 5 until the reinforcement plate 6 and the I-shaped steel beam 5 are pressed together. When the support seat 21 moves upward, the guide telescopic rod 264 extends accordingly, and the guide telescopic rod 264 guides the support seat 21, thereby improving the stability of the movement of the support seat 21.

[0046] See also Figure 5 and Figure 6 The follower assembly includes a limiting bead 266 that slides along the radial direction inside the gear 251. A compression spring 267 is provided on the side of the limiting bead 266 away from the center of the gear 251, and a groove for the limiting bead 266 to engage with is opened on the threaded rod 263.

[0047] When in use, when the threaded rod 263 drives the movable column 262 to extend downward, due to the engagement of the limiting bead 266 with the threaded rod 263, the threaded rod 263 will drive the gear 251 to rotate together, so that the gear 251 drives the rack 252 to drive the clamping plate 24 to move in the direction close to the support seat 21 to center and clamp the reinforcing plate 6. Before the reinforcing plate 6 and the I-shaped steel beam 5 are pressed together, the clamping plate 24 completes the centering and clamping of the reinforcing plate 6, and then the threaded rod 263 continues to push the movable column 262 to extend downward. At this time, since the left and right clamping plates 24 are clamped at the left and right ends of the reinforcing plate 6 and cannot move closer to each other, the gear 251 cannot rotate with the threaded rod 1 263. At this time, the rotational force of the threaded rod 1 263 will overcome the resistance of the engagement between the limiting bead 266 and the threaded rod 1 263, causing the limiting bead 266 to move away from the center of the gear 251 and disengage from the groove on the threaded rod 1 263, allowing the threaded rod 1 263 to continue rotating and drive the movable column 262 to extend downward until the reinforcing plate 6 and the I-shaped steel beam 5 are pressed against each other.

[0048] See also Figure 1 、 Figure 2 、 Figure 7 and Figure 8 The welding unit 3 includes an elastic telescopic component 31 installed on a driving motor 152, a top plate 32 is installed on the top of the elastic telescopic component 31, a laser welding head 33 is installed on the bottom of the top plate 32 for sliding back and forth, an adjustment component 2 34 for adjusting the laser welding head 33 back and forth is installed on the top plate 32, and a roller 35 located above the guide frame 42 is rotatably installed at the front end of the top plate 32.

[0049] During specific use, the elastic telescopic component 31, the top plate 32 and the laser welding head 33 are driven to move left and right by the driving motor 152. During the movement of the laser welding head 33, the roller 35 rolls along the top of the guide frame 42. The guide frame 42 is used to support and guide the roller 35, so that the laser welding head 33 can move along the trajectory of the weld between the I-shaped steel beam 5 and the reinforcement plate 6. The laser welding head 33 is aligned with the weld between the I-shaped steel beam 5 and the reinforcement plate 6 for welding. There is no need to manually weld the reinforcement plate 6, which reduces the burden on workers and improves the welding efficiency of the reinforcement plate 6.

[0050] See also Figure 1 、 Figure 7 and Figure 8 The elastic telescopic component 31 includes a fixed frame 311 fixedly connected to the front side of the driving motor 152, and a movable frame 312 is installed on the top of the fixed frame 311 for sliding up and down. A return spring 313 is fixedly connected between the top end of the fixed frame 311 and the bottom end of the movable frame 312 for pushing the movable frame 312 to move downward.

[0051] During specific use, the return spring 313 is used to give the movable frame 312 a downward elastic force, so that the movable frame 312 has a tendency to pull the top plate 32, the laser welding head 33 and the roller 35 downward, so that the roller 35 can be pressed against the top of the guide frame 42. In the process of the roller 35 moving along the guide frame 42, when the top plate 32 and the laser welding head 33 move up and down, the return spring 313 will be compressed or extended as the laser welding head 33 moves up and down, providing an adaptive change in the up and down movement of the laser welding head 33, so that the laser welding head 33 can always be aligned with the weld between the I-shaped steel beam 5 and the reinforcing plate 6.

[0052] See also Figure 1 、 Figure 2 、 Figure 7 and Figure 8The adjusting component 2 34 includes a threaded rod 2 341 rotatably mounted on the top plate 32, and a slider 2 342 is threadedly connected to the threaded rod 2 341. The slider 2 342 is connected to the top plate 32 for sliding back and forth. The front end of the threaded rod 2 341 rotates and passes through the front side of the top plate 32 and is fixedly connected to a hand wheel 343. The laser welding head 33 is fixedly mounted on the bottom of the slider 2 342. An adjusting component 14 for adjusting the cross frame 13 front and back is installed on the bottom horizontal section of the hanging unit 1. The structure of the adjusting component 14 is the same as that of the adjusting component 2 34.

[0053] During specific use, when reinforcing different I-shaped steel beams 5, due to the different widths of the I-shaped steel beams 5, before welding, the handwheel 343 is rotated to drive the threaded rod 2 341 to rotate, so that the threaded rod 2 341 drives the slider 2 342 to move forward or backward, thereby adjusting the front and rear positions of the laser welding head 33, which is convenient for using different I-shaped steel beams 5. Similarly, by adjusting the component 14 to drive the cross frame 13 to move forward and backward, the position of the support seat 21 can be adjusted forward and backward, so that the reinforcement plate 6 is in the front and rear center when it is pressed against the I-shaped steel beam 5, which is conducive to maintaining force balance and improving the reinforcement effect.

[0054] In the description of the present invention, it should also be noted that, unless otherwise expressly specified or limited, the terms "disposed," "connected," "installed," and "connected" should be understood in a broad sense. For example, they may refer to fixed or detachable connections, integral or sliding connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.
