Description

Technical Field

[0001] This invention belongs to the field of building construction technology, and more specifically, relates to an auxiliary connection device for beam and column formwork in buildings. Background Technology

[0002] When pouring beams and columns, assemble the formwork according to the set dimensions so that the formwork surrounds the reinforcing bars, and then set steel beams on the outside of the formwork to reinforce and fix the formwork.

[0003] CN114837349A discloses a lightweight formwork and a precast hollow beam-column with a formed reinforcing cage. The formwork comprises multiple templates, which enclose a box-shaped structure open at both ends or open on one side and both ends. Multiple reinforcing bars are spaced along the length of the box-shaped structure. Multiple stirrups are also provided between the reinforcing bars, wrapped around the outside of the reinforcing bars and between the reinforcing bars, and fixedly connected to them, forming a reinforcing cage. Multiple fastening devices are provided on the outside of the template, allowing the template to be fixedly connected to the reinforcing cage via these devices. When the box-shaped structure is used for precast beams, the fastening devices further include multiple reinforcing members and multiple tie rods. The reinforcing members are located on opposite sides of the box-shaped structure, between the template and the fixed frame, and are arranged along the length of the reinforcing bars. There is a gap between adjacent reinforcing members. The two ends of the tie rods penetrate the templates on opposite sides of the box-shaped structure and exit through the gap between adjacent reinforcing members. Two fastening nuts are also provided at both ends of the tie rods for fixing the tie rods and reinforcing members. In this type of template structure, the template is reinforced along its length by long strip-shaped reinforcing members. However, since the length of the reinforcing members is limited, they are generally standard length members. In order to form a long reinforcing member, multiple reinforcing members are spliced ​​together to form a long reinforcing member. Steel beams are set at the joints of adjacent reinforcing members, and the two ends of the steel beams overlap with the two adjacent reinforcing members respectively. Then, bolts are passed vertically through the steel beams and the reinforcing members.

[0004] Existing beam-column formwork connection methods can only restrict the vertical movement of adjacent reinforcement members, cannot effectively pre-tighten adjacent reinforcement members along the length direction, cannot adjust the bonding force between adjacent reinforcement members along the length direction, and cannot achieve a unified structure of reinforcement components along the length direction. Summary of the Invention

[0005] In view of this, the present invention provides an auxiliary connection device for beam and column formwork in construction, which can solve the problems of existing beam and column formwork connection methods that can only restrict the vertical movement of adjacent reinforcing members, cannot effectively pre-tighten the movement of adjacent reinforcing members along the length direction, cannot adjust the bonding force between adjacent reinforcing members along the length direction, and cannot realize that the reinforcing components are an integral structure along the length direction.

[0006] This invention is implemented as follows:

[0007] This invention provides an auxiliary connection device for beam and column formwork in construction, comprising a steel beam, a fixing component, a pushing component, a connecting component, and a vibration damping component. The fixing component comprises two parts, each connecting adjacent steel beams, and each fixing component has a through groove along its length. The pushing component comprises a first pushing member and a second pushing member, which are respectively disposed on opposite sides of the two fixing components. The connecting component comprises a bolt and a nut, the threaded section of which slides through the first and second pushing members, and the nut slides through the through groove of the fixing component. The vibration damping component is disposed inside the fixing component to reduce vibrations generated when the beam and column formwork in construction sways.

[0008] The shock absorption assembly includes sliders and tension springs. There are four sliders, which are fixedly connected to each other by the tension springs. The top of each slider is fixedly connected to a fixing assembly, and the bottom of each tension spring is fixedly connected to another fixing assembly.

[0009] Based on the above technical solution, the auxiliary connection device for beam and column formwork of the present invention can be further improved as follows:

[0010] The second pushing member includes a first pushing part, a second pushing part, a limiting part, and a connecting part. The second pushing part is slidably connected to the first pushing part. The sliding direction of the second pushing part is set along the length direction of the steel beam. The second pushing part forms a conical cavity, the axis of which is perpendicular to the sliding direction of the first pushing part. The limiting part is inserted into the conical cavity and has a conical surface that matches the inner wall of the conical cavity. The conical surface has an installation groove. The connecting part connects the limiting part and the first pushing part. The connecting part slides through the through groove through the fixing assembly. The nut is located on the side of the second pushing member away from the fixing assembly and is threadedly connected to the threaded section of the bolt.

[0011] The bottom of the conical cavity is provided with a through hole penetrating the second pushing part. The through hole is coaxially arranged with the conical cavity, and the outer diameter of one end of the through hole that connects to the conical cavity is equal to the inner diameter of the small diameter end of the conical cavity. The end of the through hole near the conical cavity is conical.

[0012] A handle is provided at the top of the connector.

[0013] The through groove can be long, oval, or arc-shaped; the fixing components can be any form of fixing lug, fixing block, or fixing strip. Reinforcing ribs or reinforcing plates can be provided on both sides of the fixing lug and other structures to strengthen the connection between the fixing lug and the steel beam. The fixing components and the steel beam can be fixed by welding, bonding, or bolting.

[0014] By providing a through hole, the bottom of the conical cavity is kept open. When impurities enter the conical cavity, they can slide along the inner wall of the cavity and the inside of the through hole past the second pushing part 3. This prevents impurities from remaining and accumulating inside the conical cavity, avoids prolonged contact with the interior of the cavity which could lead to corrosion of the inner wall, and prevents impurities from obstructing the limiting part from penetrating deeper into the conical cavity. Impurities include water, mud, dust, etc.

[0015] By providing a handle, the connecting part can be rotated using the handle. The connecting part can be a stud, screw, etc.

[0016] Furthermore, a groove is provided on the side of the first pushing part near the fixed component, the groove is arranged along the length direction of the steel beam, the nut is abutted on the side of the first pushing part away from the fixed component, a threaded hole communicating with the groove is provided on the outer wall of the first pushing part, the axis of the threaded hole is perpendicular to the length direction of the steel beam, the second pushing part slides and is inserted into the groove, and the connecting part is threadedly connected to the threaded hole.

[0017] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by opening a groove on the first pushing part and inserting the second pushing part into the groove, the sliding connection between the second pushing part and the first pushing part is realized; by opening a threaded hole on the first pushing part and making the connecting part threadedly connected to the threaded hole, the connection between the connecting part and the first pushing part is realized; when it is necessary to adjust the position of the limiting part, the connecting part is rotated, and the connecting part drives the limiting part to move relative to the conical cavity.

[0018] Furthermore, the second pusher also includes a fitting part and a display part. The fitting part is disposed in the mounting groove and slidably connected to the inner wall of the mounting groove. The outer wall of the fitting part fits against the inner wall of the conical cavity. The display part connects the fitting part and the limiting part. The portion of the display part protruding from the second pusher is used to display the fitting state between the limiting part and the inner wall of the conical cavity.

[0019] The number of the bonding part and the display part can be one or more.

[0020] By setting up a fitting part and a display part, the operator can judge whether the limiting part is fitting the conical cavity by observing the status of the display part 32f. This avoids the limiting part from penetrating too far, which would cause excessive separation force between the limiting part and the conical cavity. It also avoids the limiting part from penetrating too far, which would cause line contact between the limiting part and the inner wall of the conical cavity. This prevents long-term line contact from affecting the limiting part.

[0021] Furthermore, the connecting part has a first channel in a direction perpendicular to the sliding direction of the second pushing part, the limiting part has a second channel connecting the mounting groove and the first channel, the display part is movably disposed in the second channel, and the display part is drivenly connected to the limiting part to display the fitting state of the limiting part and the inner wall of the conical cavity.

[0022] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the bonding part can slide into and out of the mounting groove by sliding or rotating, thereby driving the display part to rotate or slide in the second channel. The bonding part can be rotated or slid to show the bonding state between the limiting part and the inner wall of the conical cavity.

[0023] Furthermore, the fitting part is slidably inserted into the mounting groove, and the display part is slidably inserted into the second channel. The second pushing member also includes a first elastic part, a second elastic part, and a first connecting rope. The first elastic part connects the fitting part and the limiting part, and is used to provide elastic force for the fitting part to extend out of the mounting groove. The second elastic part connects the display part and the connecting part, and is used to provide elastic force for the display part to protrude out of the second channel. The stiffness coefficient of the second elastic part is less than that of the first elastic part. The first connecting rope connects the fitting part and the display part, and is used to determine the fitting condition of the fitting part with the inner wall of the conical cavity by using a signal that the tops of the display part and the connecting part are aligned.

[0024] The mating part can be slidably connected by the cooperation of a groove and a block, or by a slide rail; the first elastic part can be a spring, an elastic block, or an elastic strip, etc.

[0025] Furthermore, a screw threadedly connected to the display part is rotatably provided at the end of the display part away from the first connecting rope. A rotating block is also provided at the end of the display part away from the first connecting rope. The rotating block has a rotating hole relative to the screw. The rotating block can be rotatably sleeved on the threaded section of the screw through the rotating hole and is located between the head of the screw and the display part. The rotating block abuts against the top of the connecting part by rotating. A damping layer is provided on the side of the rotating block opposite to the display part. The damping layer connects to the rotating block and fits against the display part to provide rotational damping for the rotation of the rotating block.

[0026] The damping layer can be made of materials such as rubber, latex, and silicone.

[0027] Furthermore, the fitting part is rotatably connected to the inner wall of the mounting groove, and the display part is rotatably connected to the inner wall of the second channel. The second pushing member also includes a third elastic part, a fourth elastic part, and a second connecting rope. The third elastic part connects the fitting part and the limiting part, and is used to provide an elastic force for the fitting part to rotate out of the mounting groove. The fourth elastic part connects the display part and the connecting part, and is used to provide an elastic force for the display part to rotate to be flush with the top of the connecting part. The stiffness coefficient of the fourth elastic part is less than that of the third elastic part. The second connecting rope connects the connecting part and the display part.

[0028] The fitting part can rotate with the limiting part 32c through a pivot, pivot pin or other means; the third elastic part can be a spring, torsion spring, elastic strip or elastic block or the like.

[0029] Furthermore, the connection point between the second connecting rope and the fitting part is offset from the rotation center of the fitting part, and the connection point between the second connecting rope and the fitting part extends out of the mounting groove following the fitting part; the connection point between the second connecting rope and the display part is offset from the rotation center of the display part.

[0030] A blocking block is formed in the second channel. The blocking block is located on the side of the display unit that is away from the second connecting rope. The blocking block is disposed on the rotation path of the display unit to limit the rotation range of the display unit.

[0031] The beneficial effects of adopting the above-mentioned improved scheme are as follows: With the above-mentioned arrangement, when the third elastic part pushes the fitting part to extend outward, the fitting part drives the second connecting rope to extend outward, the second connecting rope drives the display part to rotate, and the display part rotates while compressing the fourth elastic part; during the process of the fitting part fitting against the inner wall of the conical cavity, the fitting part drives the second connecting rope to move into the mounting groove, and the display part is pushed to reset under the action of the elastic restoring force of the third elastic part, so that the display part can rotate to be flush with the top of the connecting part.

[0032] The bonding part and the display part can be blocks or sheets of various shapes, such as round or square.

[0033] The blocking block can block the rotation range of the mating part and prevent the bottom of the mating part from rotating out of the mounting groove.

[0034] Furthermore, the inner wall at the junction of the first and second channels has a smooth transition.

[0035] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: through the above-mentioned setting, it is possible to avoid sharp corners at the connection between the first channel and the second channel, and to avoid sharp corners from wearing down the sliding first connecting rope and the second connecting rope.

[0036] Compared with the prior art, the beneficial effect of the auxiliary connection device for beam and column formwork of the present invention is as follows: By setting a second pushing member, when it is necessary to disassemble adjacent steel beams, the connecting part is rotated, and the connecting part drives the limiting part to rotate. The limiting part moves in the direction of disengaging from the conical cavity. At this time, the sliding connection between the first pushing part and the second pushing part loses the force that restricts the relative sliding, so that the first pushing part can slide relative to the second pushing part, and the clamping force applied to the first pushing member and the second pushing member by the bolt and nut is released. Then, the first pushing member and the second pushing member are rotated, so that the first pushing member and the second pushing member pass through the through groove through the two fixed components, realizing the separation of the first pushing member and the second pushing member relative to the fixed components. During separation, the clamping force applied to the first pushing member and the second pushing member by the bolt and nut can be released by simply rotating the connecting part, avoiding the need to apply a large force to rotate the nut to release the clamping force. By creating a conical cavity in the second pushing part and inserting the limiting part into the conical cavity, ensuring that the conical surface of the limiting part fits against the inner wall of the conical cavity, when the bolt and nut apply clamping force to the second pushing part, the fit between the conical surface of the limiting part and the inner wall of the conical cavity restricts the sliding of the second pushing part relative to the first pushing part. The fit between the conical surface and the inner wall of the conical cavity increases the contact area, preventing line contact that could concentrate clamping force at a single point and avoiding damage to the limiting part during prolonged clamping. Furthermore, when it is necessary to contact the limiting part with the conical cavity, rotating the connecting part causes the limiting part to move away from the second pushing part. At this time, under the action of the clamping force, the second... The pushing part slides relative to the first pushing part in the direction closer to the limiting part, which can reduce the clamping force applied to the second pushing member by the bolt and nut, and facilitate the rotation of the first pushing member and the second pushing member relative to the fixed assembly. After the limiting part and the second pushing part move, the coaxiality between the limiting part and the conical cavity is broken. At this time, the limiting part and the conical cavity become line contact, which reduces the sliding damping of the limiting part relative to the conical cavity. The conical limiting part is easy to slide relative to the inner wall of the conical cavity, which facilitates the rotation of the connecting part and the movement of the limiting part relative to the connecting part. Moreover, when the inner wall of the conical cavity applies force to the limiting part, the conical surface has an upward separation, which can help the limiting part slide away from the conical cavity.

Shock absorption assembly. Detailed Implementation

[0055] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0056] like Figure 1-15 The diagram shows a structural schematic of an auxiliary connection device for beam and column formwork provided by the present invention. The device includes a steel beam 1, a fixing component 2, a pushing component 3, a connecting component 4, and a shock-absorbing component 5. The fixing component 2 comprises two parts, each connecting an adjacent steel beam 1. Each fixing component 2 has a through groove 21 along its length. The pushing component 3 includes a first pushing member 31 and a second pushing member 32, which are respectively disposed on opposite sides of the two fixing components 2. The connecting component 4 includes a bolt 41 and a nut 42. The threaded section of the bolt 41 slides through the first pushing member 31 and the second pushing member 32, and the nut 42 slides through the through groove 21 into the fixing component 2. The fixing component 2 contains a shock-absorbing component 5, which is used to reduce vibrations generated when the beam and column formwork sways.

[0057] The shock absorption assembly 5 includes sliders and tension springs. There are 4 sliders, which are fixedly connected to each other by tension springs. The top of the slider is fixedly connected to the fixing assembly 2, and the bottom of the tension spring is fixedly connected to another fixing assembly 2.

[0058] In the above technical solution, the second pushing member 32 includes a first pushing part 321, a second pushing part 322, a limiting part 323, and a connecting part 324. The second pushing part 322 is slidably connected to the first pushing part 321. The sliding direction of the second pushing part 322 is set along the length direction of the steel beam 1. The second pushing part 322 forms a conical cavity. The axis of the conical cavity is perpendicular to the sliding direction of the first pushing part 321. The limiting part 323 is inserted into the conical cavity and has a conical surface that matches the inner wall of the conical cavity. The conical surface has an installation groove. The connecting part 324 connects the limiting part 323 and the first pushing part 321. The connecting part 324 slides through the fixing component 2 via the through groove 21. The nut 42 is set on the side of the second pushing member 32 away from the fixing component 2 and is threadedly connected to the threaded section of the bolt 41.

[0059] The bottom of the conical cavity is provided with a through hole that penetrates the second pushing part 322. The through hole is coaxially arranged with the conical cavity, and the outer diameter of the end of the through hole that connects to the conical cavity is equal to the inner diameter of the small diameter end of the conical cavity. The end of the through hole that is close to the conical cavity is conical.

[0060] A handle is provided on the top of the connecting part 324.

[0061] In use, when it is necessary to fix the steel beam 1 along its axis, the fixing component 2 is connected to two adjacent steel beams 1 respectively. Then, the first pusher 31 and the second pusher 32 are respectively placed on the opposite sides of the two fixing components 2. Then, the bolt 41 is passed through the first pusher 31, the two fixing components 2, the second pusher 322, and the first pusher 321 in sequence. Then, the nut 42 is tightened. At this time, during the tightening of the nut 42, the head of the nut 42 and the bolt 41 pushes the first pusher 31 and the second pusher 32 to clamp the two fixing components 2, so that the two fixing components 2 apply a clamping force to the two adjacent steel beams 1 to move closer to each other, preventing the two steel beams 1 from moving away from each other. When it is necessary to disassemble the connecting component 4, the connecting part 324 is rotated, and the connecting part 324 drives the limiting part 323 to rotate. When the limiting part 323 moves in the direction of disengaging from the conical cavity, the force restricting the relative sliding between the sliding first pushing part 321 and the second pushing part 322 is lost, allowing the first pushing part 321 to slide relative to the second pushing part 322. This releases the clamping force applied to the first pushing part 31 and the second pushing part 32 by the bolt 41 and the nut 42. Then, the first pushing part 31 and the second pushing part 32 are rotated, allowing the first pushing part 31 and the second pushing part 32 to pass through the two fixing components 2 via the through groove 21, thus achieving the separation of the first pushing part 31 and the second pushing part 32 relative to the fixing components 2. During separation, the clamping force applied to the first pushing part 31 and the second pushing part 32 by the bolt 41 and the nut 42 can be released simply by rotating the connecting part 324, avoiding the need to apply a large force to rotate the nut 42 to release the clamping force.

[0062] By creating a conical cavity in the second pushing part 322, the limiting part 323 is inserted into the conical cavity, and the conical surface of the limiting part 323 is made to fit against the inner wall of the conical cavity. At this time, when the bolt 41 and nut 42 apply clamping force to the second pushing part 32, the fit between the conical surface of the limiting part 323 and the inner wall of the conical cavity can restrict the sliding of the second pushing part 322 relative to the first pushing part 321. The fit between the conical surface and the inner wall of the conical cavity increases the contact area, which can avoid line contact causing the clamping force to concentrate at one point and prevent damage to the limiting part 323 during long-term clamping. Moreover, when it is necessary to contact the limiting part 323 with the limiting of the conical cavity, the connecting part 324 is rotated, and the connecting part 324 drives the limiting part 323 to move away from the second pushing part 322. At this time, under the action of clamping force, the second pushing part 322 2. Sliding towards the limiting part 323 relative to the first pushing part 321 can reduce the clamping force applied to the second pushing member 32 by the bolt 41 and nut 42, making it easier for the first pushing member 31 and the second pushing member 32 to rotate relative to the fixed assembly 2. After the limiting part 323 and the second pushing part 322 move, the coaxiality between the limiting part 323 and the conical cavity is broken. At this time, the limiting part 323 and the conical cavity become line contact, reducing the sliding damping of the limiting part 323 relative to the conical cavity. The conical limiting part 323 is easy to slide relative to the inner wall of the conical cavity, making it easy to rotate the connecting part 324 and move the limiting part 323 relative to the connecting part 324. Moreover, when the inner wall of the conical cavity applies force to the limiting part 323, the conical surface has an upward separation, which can help the limiting part 323 slide away from the conical cavity.

[0063] The connecting part 324 is slidably inserted into the first pushing part 321, allowing the connecting part 324 to move relative to the first pushing part 321 and drive the limiting part 323 to move relative to the second pushing part 322. The sliding connecting part 324 is fixed with screws, thus fixing the sliding second pushing part 322 and the limiting part 323. Alternatively, the connecting part 324 can be threadedly connected to the first pushing part 321. This threaded connection allows the connecting part 324 to drive the limiting part 323 to move relative to the second pushing part 322, and the self-locking nature of the thread fixes the rotated connecting part 324 and the limiting part 323.

[0064] Furthermore, in the above technical solution, the first pushing part 321 has a sliding groove on the side near the fixed component 2, the sliding groove is arranged along the length direction of the steel beam 1, the side of the first pushing part 321 away from the fixed component 2 is abutted by a nut 42, the outer wall of the first pushing part 321 has a threaded hole that communicates with the sliding groove, the axis of the threaded hole is perpendicular to the length direction of the steel beam 1, the second pushing part 322 slides and is inserted into the sliding groove, and the connecting part 324 is threadedly connected to the threaded hole.

[0065] During use, when rotating the connecting part 324 to insert the limiting part 323 into the conical cavity, the environment at the construction site is generally relatively harsh, which may cause impurities in the conical cavity or threaded hole to obstruct the rotation of the connecting part 324 in some places. This may lead the operator to mistakenly believe that the limiting part 323 has moved to the preset state. However, in reality, the limiting part 323 is still a certain distance away from the preset position in the conical cavity. When the bolt 41 and nut 42 apply clamping force to the second pushing member 32, they will push the limiting part 323 to abut against the inner wall of the conical cavity. However, at this time, the limiting part 323 and the conical cavity are in line contact. Prolonged line contact will cause the conical surface of the limiting part 323 to wear faster, affecting the roundness of the conical surface and increasing the rotational damping of the limiting part 323 relative to the conical cavity.

[0066] Furthermore, in the above technical solution, the second pusher 32 also includes a fitting part 325 and a display part 326. The fitting part 325 is disposed in the mounting groove and is slidably connected to the inner wall of the mounting groove. The outer wall of the fitting part 325 fits the inner wall of the conical cavity. The display part 326 connects the fitting part 325 and the limiting part 323. The portion of the display part 326 protruding from the second pusher 322 is used to display the fitting state of the limiting part 323 and the inner wall of the conical cavity.

[0067] During use, as the limiting part 323 slides into the conical cavity, sliding or rotating causes the fitting part 325 of the limiting part 323 to gradually contact the inner wall of the conical cavity. When the fitting part 325 fits the inner wall of the conical cavity, the display part 326 can display the fitting of the fitting part 325 with the conical cavity, and at this time the movement of the limiting part 323 is stopped.

[0068] Furthermore, in the above technical solution, the connecting part 324 has a first channel in a direction perpendicular to the sliding direction of the second pushing part 322, the limiting part 323 has a second channel connecting the mounting groove and the first channel, the display part 326 is movably disposed in the second channel, and the display part 326 is connected to the limiting part 323 for displaying the fitting state of the limiting part 323 and the inner wall of the conical cavity.

[0069] Furthermore, in the above technical solution, the fitting part 325 is slidably inserted into the mounting groove, the display part 326 is slidably inserted into the second channel, and the second pusher 32 also includes a first elastic part 327, a second elastic part 328, and a first connecting rope 329. The first elastic part 327 connects the fitting part 325 and the limiting part 323, and is used to provide elastic force for the fitting part 325 to extend out of the mounting groove. The second elastic part 328 connects the display part 326 and the connecting part 324, and is used to provide elastic force for the display part 326 to protrude out of the second channel. The stiffness coefficient of the second elastic part 328 is less than that of the first elastic part 327. The first connecting rope 329 connects the fitting part 325 and the display part 326, and is used to determine the fitting condition of the fitting part 325 with the inner wall of the conical cavity by the signal that the tops of the display part 326 and the connecting part 324 are flush.

[0070] In use, the second elastic part 328 pushes the fitting part 325 out of the mounting groove. When the limiting part 323 is inserted into the conical cavity, the fitting part 325 gradually contacts the inner wall of the conical cavity. Under the action of the inner wall of the conical cavity, the fitting part 325 compresses the first elastic part 327 and gradually slides into the mounting groove. During the process of the fitting part 325 sliding into the mounting groove, the force applied to the display part 326 by the first elastic part 327 through the first connecting rope 329 decreases. Under the push of the elastic force of the second elastic part 328, the display part 326 slides out of the mounting groove. When the limiting part 323 moves to the inner wall of the conical cavity, the fitting part 325 can no longer move in the direction of penetrating the mounting groove. At this time, the top of the first connecting rope 329 is flush with the top of the connecting part 324, indicating that the limiting part 323 has moved to the preset position in the conical cavity. The limiting part 323 fits the conical cavity with appropriate force, which can avoid the limiting part 323 from being over-fitted to the inner wall of the conical cavity and can avoid the limiting part 323 from not fitting properly to the inner wall of the conical cavity.

[0071] Furthermore, in the above technical solution, a screw is rotatably provided at the end of the display part 326 away from the first connecting rope 329, and is threadedly connected to the display part 326. A rotating block is also provided at the end of the display part 326 away from the first connecting rope 329. The rotating block has a rotating hole relative to the screw. The rotating block can be rotatably sleeved on the threaded section of the screw through the rotating hole and is located between the head of the screw and the display part 326. The rotating block abuts against the top of the connecting part 324 by rotating. A damping layer is provided on the side of the rotating block opposite to the display part 326. The damping layer connects to the rotating block and fits against the display part 326 to provide rotational damping for the rotation of the rotating block.

[0072] In use, during the process of pulling the limiting part 323 out of the conical cavity, first rotate the rotating block. The rotating block drives the damping layer to move, and the damping layer rubs against the display part 326. When the rotating block rotates to partially abut the top of the connecting part 324, stop rotating the display part 326. At this time, the display part 326 cannot move into the second channel due to the restriction of the rotating block. The display part 326 is fixed to the fitting part 325 by the first connecting rope 329, so that the fitting part 325 cannot slide out of the mounting groove under the action of the first elastic part 327. At this time, pulling out the limiting part 323 will not obstruct the fitting part 325. The limiting part 323 is pulled out of the conical cavity; when the display part 326 needs to display the moving state of the fitting part 325, the rotating block is rotated so that the rotating block rotates above the display part 326. At this time, the rotating block will not obstruct the sliding of the display part 326; by providing a damping layer, the damping layer can provide rotational damping for the rotation of the rotating block relative to the display part 326, which can prevent the rotating block from sliding randomly, so that the rotating block 3 can only rotate under the push of a person, and prevent the rotating block from rotating randomly and affecting the engagement between the rotating block and the connecting part 324 or the sliding of the display part 326 relative to the connecting part 324.

[0073] Furthermore, in the above technical solution, the fitting part 325 is rotatably connected to the inner wall of the mounting groove, the display part 326 is rotatably connected to the inner wall of the second channel, and the second pusher 32 also includes a third elastic part, a fourth elastic part, and a second connecting rope. The third elastic part connects the fitting part 325 and the limiting part 323, and is used to provide elastic force for the fitting part 325 to rotate out of the mounting groove. The fourth elastic part connects the display part 326 and the connecting part 324, and is used to provide elastic force for the display part 326 to rotate to be flush with the top of the connecting part 324. The stiffness coefficient of the fourth elastic part is less than that of the third elastic part. The second connecting rope connects the connecting part 324 and the display part 326.

[0074] In use, the third elastic part pushes the fitting part 325 to rotate and extend out of the mounting groove. When the limiting part 323 is inserted into the conical cavity, the fitting part 325 gradually contacts the inner wall of the conical cavity. Under the action of the inner wall of the conical cavity, the fitting part 325 compresses the third elastic part and gradually slides into the mounting groove. During the process of the fitting part 325 sliding into the mounting groove, the force applied to the display part 326 by the third elastic part through the second connecting rope decreases. Under the push of the elastic force of the fourth elastic part, the display part 326 rotates in the second channel. When the fitting part 325 rotates to fit the inner wall of the conical cavity, the limiting part 323, which is fitted to the inner wall of the conical cavity, cannot continue to move in the direction of penetrating the mounting groove. At this time, the top of the display part 326 rotates to be flush with the top of the connecting part 324, indicating that the limiting part 323 has moved to the preset position in the conical cavity. The limiting part 323 fits the conical cavity with appropriate force, which can prevent the limiting part 323 from being over-fitted to the inner wall of the conical cavity, and can prevent the limiting part 323 from not fitting properly to the inner wall of the conical cavity.

[0075] During the process of pulling the limiting part 323 out of the conical cavity, the display part 326 is squeezed, causing the display part 326 to rotate into the second channel from the side of the second connecting rope. This causes the display part 326 to move the fitting part 325 into the mounting groove through the second connecting rope. This prevents the fitting part 325 from rotating into the mounting groove during the process of pulling out the limiting part 323, and prevents the fitting part 325 from getting stuck on the inner wall of the conical cavity, which would prevent the limiting part 323 from sliding out of the conical cavity.

[0076] Furthermore, in the above technical solution, the connection point between the second connecting rope and the fitting part 325 is offset from the rotation center of the fitting part 325, and the connection point between the second connecting rope and the fitting part 325 extends out of the mounting groove along with the fitting part 325; the connection point between the second connecting rope and the display part 326 is offset from the rotation center of the display part 326.

[0077] A blocking block is formed in the second channel. The blocking block is located on the side of the display unit 326 that is away from the second connecting rope. The blocking block is set on the rotation path of the display unit 326 to limit the rotation range of the display unit 326.

[0078] Furthermore, in the above technical solution, the inner wall of the connection between the first channel and the second channel has a smooth transition.

[0079] Specifically, the principle of this invention is as follows: When it is necessary to fix the steel beam 1 along its axis, the fixing components 2 are connected to two adjacent steel beams 1 respectively. Then, the first pushing member 31 and the second pushing member 32 are respectively placed on the opposite sides of the two fixing components 2. Then, the bolt 41 is passed through the first pushing member 31, the two fixing components 2, the second pushing part 322, and the first pushing part 321 in sequence. Then, the nut 42 is tightened. At this time, during the tightening process of the nut 42, the head of the nut 42 and the bolt 41 pushes the first pushing member 31 and the second pushing member 32 to clamp the two fixing components 2, so that the two fixing components 2 apply a clamping force to the two adjacent steel beams 1 to move closer to each other, preventing the two steel beams 1 from moving away from each other. When it is necessary to disassemble the connecting component 4, the connecting part 324 is rotated, and the connecting part 324 drives the limiting part 3. 23 rotates, and the limiting part 323 moves in the direction of disengaging from the conical cavity. At this time, the sliding connection between the first pushing part 321 and the second pushing part 322 loses the force that restricts the relative sliding, so that the first pushing part 321 can slide relative to the second pushing part 322, releasing the clamping force applied to the first pushing part 31 and the second pushing part 32 by the bolt 41 and the nut 42. Then, the first pushing part 31 and the second pushing part 32 are rotated, so that the first pushing part 31 and the second pushing part 32 pass through the through groove 21 through the two fixing components 2, realizing the separation of the first pushing part 31 and the second pushing part 32 relative to the fixing components 2. During separation, the clamping force applied to the first pushing part 31 and the second pushing part 32 by the bolt 41 and the nut 42 can be released by simply rotating the connecting part 324, avoiding the need to apply a large force to rotate the nut 42 to release the clamping force.
