Description

Technical Field

[0001] The invention relates to the technical field of steel structure buildings, and in particular to the technical field of steel structure connection. Background Art

[0002] Steel structure buildings are building structures mainly made of steel, including steel beams, steel columns, trusses and other steel structures made of steel sections, steel plates and the like. Each steel structure is usually fixed and connected by welding, bolts, rivets and the like. For example, when a steel column is fixedly connected to a steel beam, the steel column is generally fixed first, and then the steel beam is lifted by a crane or other technology, and the steel beam is pulled to a preset position and aligned with the steel column. Then, workers complete the connection and fixation between the steel column and the steel beam by bolts, angle steel and other technologies. For example, the patent document with authorization announcement number CN217326532U or the patent document with authorization announcement number CN219952233U discloses the connection of steel structures by bolts or angle steel and other technologies. However, this technology has some shortcomings, such as:

[0003] 1. When the steel beam is moved by the crane, the connection between the crane and the steel beam is generally achieved through a steel cable. During the traction process, the steel beam will shake slightly. If the connection is not stable enough, the steel beam is prone to tilt and fall, which is dangerous. For example, the application publication number CN115744595A discloses that the crane hoisting steel structure is prone to slippage and tripping.

[0004] 2. During the long-term use after the connection and fixation are completed, the connection stress between the steel column and the steel beam is mainly concentrated at the connection, that is, at the bolt. Therefore, the steel structure connection generally has a service life limit. Therefore, it is necessary to improve the connection method to reduce the connection stress acting on the bolts and increase the service life. In addition, the connection method should also be improved to have an anti-fall effect and improve safety.

[0005] Based on the above, the present invention proposes a steel structure connection assembly and a method of using the same. Summary of the invention

[0006] To solve the problems mentioned in the above background, the present invention provides a steel structure connection assembly and a method for using the same.

[0007] In order to achieve the above technical objectives, the technical solution adopted by the present invention is as follows.

[0008] A steel structure connection assembly includes a steel column, a steel beam and a connection piece arranged between the steel column and the steel beam, the connection piece includes a main frame, a linear rail and a threaded shaft are installed on the main frame along the length direction, the linear rail is fixedly arranged on the main frame, two slide seats are installed on the linear rail, the slide seats can move on the linear rail, the threaded shaft is rotatably connected to the main frame, two groups of anti-fall components are also installed on the linear rail, and the two slide seats are located between the two groups of anti-fall components.

[0009] As a further improvement and optimization of the present invention, the anti-falling component includes a connecting seat that is slidably connected to the linear rail, the threaded shaft is divided into a middle section and two threaded sections respectively located on both sides of the middle section along the axis direction, the connecting seats in the two groups of anti-falling components are respectively threadedly connected to the two threaded sections of the threaded shaft, and the thread rotation directions of the two threaded sections are opposite;

[0010] The two connecting seats are each provided with an inclined plane 1 on the side facing each other, and the inclined plane 1 is located on the side of the main frame away from the sliding seat. When the connecting piece is in use, the distance between the inclined planes 1 on the two connecting seats decreases from bottom to top along the vertical direction. The inclined plane 1 of the connecting seat is slidably connected to the anti-fall seat, and the sliding direction of the anti-fall seat is parallel to the inclination direction of the inclined plane 1.

[0011] As a further improvement and optimization of the present invention, a second slope is provided on the side of the anti-fall seat facing the connecting seat, and the second slope is in contact with the first slope to form a sliding connection. A spring is provided between the anti-fall seat and the connecting seat, and the elastic force of the spring drives the anti-fall seat to move upward on the first slope.

[0012] As a further improvement and optimization of the present invention, the two anti-fall seats are provided with reverse teeth on the opposite sides thereof, and a plurality of reverse teeth are arranged in an array along the vertical direction. When the connecting piece is in use, the bottom of the reverse teeth is in the shape of a horizontal plane, and the upper surface of the reverse teeth is arranged as an inclined slope three. The distance between the corresponding slopes three of the reverse teeth on the two anti-fall seats increases from bottom to top along the vertical direction.

[0013] As a further improvement and optimization of the present invention, a driving shaft is installed on the main frame along the width direction, the driving shaft is rotationally connected to the main frame, and the middle section of the driving shaft and the threaded shaft forms a power connection.

[0014] As a further improvement and optimization of the present invention, a power connection is formed between the drive shaft and the threaded shaft via a worm gear.

[0015] As a further improvement and optimization of the present invention, the end of the driving shaft is configured to be in a polygonal shape.

[0016] A method for using a steel structure connection component:

[0017] The steel column is provided with a connection hole 1 for connection, the steel beam is provided with a connection hole 2 for connection, the main frame is provided with a connection hole 4 for connection, the large surface of the slide is perpendicular to the extension direction of the linear rail, the large surface refers to the side with the largest area of ​​the slide, and the large surface of the slide is provided with a connection hole 3 for connection. The process of achieving fixed connection between the steel column and the steel beam through the connector includes the following steps:

[0018] Step 1: Fix and install the steel column;

[0019] Step 2: Assemble the connector on the steel column: first move the connector so that the steel column is located between the two anti-fall seats, and then drive the two connectors to move closer to each other by rotating the threaded shaft, so that the two anti-fall seats move closer to each other and the reverse teeth touch the steel column;

[0020] Step 3: Move one end of the steel beam to the two slides, and use bolts to achieve a fixed connection between the steel beam and the slides;

[0021] Step 4: Use the crane to pull the steel beam upward;

[0022] Step 5: After the steel beam moves up to the preset height, since the sliding seat can move between the two sets of anti-fall components, the worker can manually push the steel beam until the steel beam is aligned with the steel column. The steel beam, the main frame and the steel column are fixedly connected by bolts, and the two anti-fall seats are driven to hold the steel column tightly by rotating the threaded shaft.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] This application realizes the fixed connection between steel columns and steel beams through the cooperation of connecting parts and bolts. During use:

[0025] In the process of the steel beam moving up to the preset height: a. The steel beam is pulled up by the existing crane technology. Since the cooperation between the connecting piece and the steel column realizes a limiting guiding function in the vertical direction, it is only necessary to pull the steel beam up vertically, and the steel beam will not shake greatly, which can improve the safety of the steel beam hoisting process; b. During the hoisting process, if the steel beam falls, then: on the one hand, since the reverse tooth is in contact with the steel column, there is resistance between the anti-fall seat and the steel column that hinders the anti-fall seat from falling. On the other hand, in the process of pulling the steel beam up, the reason why a little force is required to move the connecting piece up is that there is friction between the reverse tooth and the steel column. Therefore, the spring will be compressed. During the falling process, the spring will release the elastic force. After the elastic force is released, the anti-fall seat will move down. Therefore, the falling speed of the anti-fall seat is significantly lower than the falling speed of the connecting seat. Under the cooperation of the first and second inclined planes, the anti-fall seat has a movement trend close to the steel column, that is, the anti-fall seat and the steel column are clamped tighter and tighter, which has an anti-fall effect and further improves safety;

[0026] When the steel beam is used after being fixedly connected to the steel column: on the one hand, the clamping force between the two anti-fall seats and the steel column shares part of the stress, making the stress applied to the bolts relatively less, thereby increasing the service life; on the other hand, after long-term use, if there is a problem with the bolts, it can play an anti-fall effect and improve safety.

[0037] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0038] Reference Figure 1-Figure 8 A steel structure connection assembly includes a steel column 100, a steel beam 200, and a connection piece 300 arranged between the steel column 100 and the steel beam 200.

[0039] Reference Figure 2 The steel column 100 is provided with a connection hole 101 for connection, and the steel beam 200 is provided with a connection hole 201 for connection.

[0040] Reference Figure 3-Figure 8 The connecting member 300 includes a main frame body 301, on which a linear rail 302 and a threaded shaft 306 are installed along the length direction, wherein the linear rail 302 is fixedly arranged on the main frame body 301, and two slides 303 are installed on the linear rail 302, and the slides 303 can move on the linear rail 302, and the threaded shaft 306 is rotatably connected to the main frame body 301, and a driving shaft 307 is installed on the main frame body 301 along the width direction, and the driving shaft 307 is rotatably connected to the main frame body 301, and a power connection is formed between the driving shaft 307 and the threaded shaft 306. Preferably, a power connection is formed by a worm gear 308, and the threaded shaft 306 can be driven to rotate by rotating the driving shaft 307. Preferably, the end of the driving shaft 307 is set to a polygonal shape, and the driving shaft 307 can be easily screwed with the help of tools such as a wrench.

[0041] The large surface of the slide 303 is perpendicular to the extension direction of the linear rail 302. The large surface refers to the side surface of the slide 303 with the largest area. The large surface of the slide 303 is provided with a connection hole 304 for connection.

[0042] Two sets of anti-falling components are also installed on the linear rail 302, and the two slide seats 303 are located between the two sets of anti-falling components.

[0043] The anti-fall component includes a connecting seat 309 that is slidably connected to the linear rail 302. The threaded shaft 306 is divided into a middle section and two threaded sections located on both sides of the middle section along the axial direction. The middle section is dynamically connected to the drive shaft 307. The threaded rotation directions of the two threaded sections are opposite. The connecting seats 309 in the two groups of anti-fall components are threadedly connected to the two threaded sections of the threaded shaft 306 respectively. Therefore, when the threaded shaft 306 rotates, the connecting seats 309 in the two groups of anti-fall components can move closer to or away from each other.

[0044] The two connecting seats 309 are each provided with an inclined surface 1 on the opposite side, and the inclined surface 1 is located on the side of the main frame 301 away from the sliding seat 303. When the connecting member 300 is in use, the distance between the inclined surfaces 1 on the two connecting seats 309 decreases from bottom to top along the vertical direction.

[0045] The first slope of the connecting seat 309 is slidably connected to the anti-fall seat 310, and the sliding direction of the anti-fall seat 310 is parallel to the inclination direction of the first slope. Specifically, the anti-fall seat 310 is provided with a second slope facing the side of the connecting seat 309, and the second slope is in contact with the first slope to form a sliding connection. In addition, a spring 312 is provided between the anti-fall seat 310 and the connecting seat 309, and the elastic force of the spring 312 drives the anti-fall seat 310 to move upward on the first slope.

[0046] Furthermore, the two anti-fall seats 310 are each provided with an anti-tooth 311 on one side facing each other, and a plurality of anti-tooths 311 are arranged in an array along the vertical direction. When the connecting piece 300 is in use, the bottom of the anti-tooth 311 is in the shape of a horizontal plane, and the upper surface of the anti-tooth 311 is arranged as an inclined slope three. The distance between the inclined surfaces three of the corresponding anti-tooths 311 on the two anti-fall seats 310 increases from bottom to top along the vertical direction. This means that when the anti-tooth 311 contacts the steel column 100, the connecting piece 300 can be moved upward with a little force, but it is more laborious to move the connecting piece 300 downward.

[0047] The main frame body 301 is also provided with a connection hole 305 for connection.

[0048] A method for using a steel structure connection component:

[0049] Step 1: Fix and install the steel column 100;

[0050] Step 2: Assemble the connecting piece 300 on the steel column 100: first move the connecting piece 300 so that the steel column 100 is located between the two anti-fall seats 310, then screw the drive shaft 307, and drive the threaded shaft 306 to rotate through the worm gear 308, thereby driving the two connecting seats 309 to move closer to each other. Even if the two anti-fall seats 310 move closer to each other, so that the reverse tooth 311 touches the steel column 100, the existing torque wrench technology can be used to screw the drive shaft 307, and the torque wrench can be used to clearly determine whether the reverse tooth 311 touches the steel column 100. Once it touches, stop screwing. At this time, with a little force, the connecting piece 300 can be driven to move upward on the steel column 100, that is, the connecting piece 300 cooperates with the steel column 100 at this time, and can play a role of limiting and guiding in the vertical direction;

[0051] Step 3: Move one end of the steel beam 200 to the two slide seats 303, and achieve a fixed connection between the steel beam 200 and the slide seats 303 by using existing bolts or screws;

[0052] Step 4: Use the existing crane technology to pull the steel beam 200 upward. Since the cooperation between the connecting piece 300 and the steel column 100 realizes a limiting guiding effect in the vertical direction, it is only necessary to pull the steel beam 200 vertically upward, and the steel beam 200 will not shake greatly. Therefore, the safety of the steel beam 200 during the hoisting process can be improved. In addition, even if the steel beam 200 falls during the hoisting process, then: on the one hand, since the reverse tooth 311 is in contact with the steel column 100, there is resistance between the anti-fall seat 310 and the steel column 100 to prevent the anti-fall seat 310 from falling. On the other hand, when the steel beam 200 is pulled upward, the anti-fall seat 310 will not fall. During the upward movement of the beam 200, the reason why a little force is required to move the connecting member 300 upward is that there is friction between the reverse tooth 311 and the steel column 100. Therefore, the spring 312 will be compressed. During the falling process, the spring 312 will release the elastic force. After the elastic force is released, the anti-fall seat 310 will move downward. Therefore, the falling speed of the anti-fall seat 310 is significantly lower than the falling speed of the connecting seat 309. Under the cooperation of the first and second inclined planes, the anti-fall seat 310 has a movement trend close to the steel column 100, that is, the anti-fall seat 310 and the steel column 100 are clamped more and more tightly, which plays an anti-fall effect and further improves safety.

[0053] Step 5: After the steel beam 200 moves up to the preset height, the worker can manually push the steel beam 200, and the slide seat 303 can move slightly between the two sets of anti-fall components until the steel beam 200 is aligned with the steel column 100. The existing bolt or screw technology is used to achieve a fixed connection between the steel beam 200, the main frame 301 and the steel column 100. By screwing the drive shaft 307, the two anti-fall seats 310 are clamped to the steel column 100. The significance of this is: on the one hand, the clamping force between the two anti-fall seats 310 and the steel column 100 can share part of the stress, so that the stress applied to the bolt is relatively less, thereby increasing the service life. On the other hand, after long-term use, if there is a problem with the bolt, it can have an anti-fall effect and improve safety.

[0054] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
