Description

Technical Field

[0001] This invention relates to the field of fence fixing device technology, and specifically to a fence fixing device for steel structure construction. Background Technology

[0002] With the promotion and adoption of prefabricated construction by the state, steel structure buildings, as the most typical form of prefabricated construction, are increasingly being used in civil and commercial buildings. For steel structures, when performing edge work near deep foundations, stairwells, roof perimeters, light well perimeters, material transfer platforms, balconies, pedestrian walkways, and unloading platforms, the safety risks during construction are significant. Therefore, it is essential to uniformly employ double-layer steel pipe protection. When the outer side of the edge work is close to the street, in addition to installing guardrails, toe boards, and safety netting, the facade should also be enclosed with hard barriers such as thorny fences to prevent danger during construction.

[0003] Existing construction fencing typically involves burying support posts in the ground and then welding the fence panels onto them. This method is mostly suitable for hard ground. For damp and soft ground, it requires the use of steel pipes, which take up more space, for fixation. Moreover, due to the damp ground, existing technology does not include reinforcement structures when fixing the fence support posts, resulting in poor fixation of the support posts in wet conditions. This not only increases the difficulty of construction but also increases construction time and workload. Furthermore, when dismantling and moving the perimeter fence after construction is completed, the perimeter fence itself lacks a labor-saving or easy-to-lift structure. Therefore, dismantling the fence support posts is not only time-consuming and labor-intensive but also inconvenient. After dismantling, the number of fence posts that can be retrieved and transported at one time is small and requires more effort, which is not conducive to the recycling and reuse of the perimeter fence support posts. Summary of the Invention

[0004] To address the aforementioned deficiencies and problems, this invention provides a perimeter fencing fixing device for steel structure construction. A switching mechanism allows for flexible switching between movable and fixed states. When the wheels are extended, the perimeter fencing and fixing device can be easily moved, improving mobility. An inserting mechanism provides auxiliary fixing via an auxiliary rod when the drill bit is inserted into the ground, enhancing the stability of the perimeter fencing when fixed on wet ground. Furthermore, the fixing device is designed as a detachable structure, and two fixing rods can be easily joined together via a splicing and merging unit. This, combined with the fixing effect of the base, improves the versatility and flexibility of the perimeter fencing.

[0005] The solution adopted by this invention to solve its technical problem is: a fixing device for edge fences in steel structure construction, comprising left and right bases, with L-shaped first and second fixing rods vertically mounted on the two bases respectively, and further comprising a switching mechanism, a fixing mechanism, and a splicing and merging unit. The switching mechanism includes a pedal vertically slidably fitted inside the base, and a movable component located behind the pedal vertically slidably fitted inside the base. A wheel is provided below the movable component. A pushing component is provided between the pedal and the movable component to control the relative movement of the pedal and the movable component. A limiting component is provided inside the base to limit the movement of the pedal. The fixing mechanism includes connecting columns vertically symmetrically and movablely fitted inside the base, with the upper end of the connecting columns fixed. The assembly includes a push-pull handle and a fixing device on the base for positioning the handle. A drill bit is vertically slidably mounted on the lower end of the connecting column, and an elastic element is provided between the connecting column and the drill bit. An auxiliary insertion rod is circumferentially hinged to the side of the drill bit, and the lower end of the auxiliary insertion rod has a protrusion that is movably fitted into a groove in the side wall of the connecting column. A connecting groove is laterally opened at the end of the first fixing rod, and the corresponding end of the second fixing rod is slidably fitted into the connecting groove. The splicing and merging unit includes a pusher at the connecting end of the second fixing rod, which can abut against the inner wall of the connecting groove. The pusher ensures that the connecting end of the second fixing rod is stably abutted against the connecting groove. A locking mechanism that cooperates with the first fixing rod to provide a limiting effect is provided on the second fixing rod.

[0006] Furthermore, the first and second fixing rods are composed of a vertical rod mounted on the base and a horizontal rod hinged to the upper end of the vertical rod. The two horizontal rods can be assembled together by splicing and merging units, so that the first and second fixing rods cooperate to form a U-shaped structure.

[0007] Furthermore, the pushing assembly includes a rotating block disposed within the base, the rotating block being located above the pedal and the moving component, the front end of the rotating block being hinged to the pedal via a movable rod one, and the rear end of the rotating block being hinged to the moving component via a movable rod two.

[0008] Furthermore, the limiting component includes a fixed shaft vertically fitted inside the bottom of the base, on which rotating ring one and rotating ring two are symmetrically mounted and rotated up and down, and on the outer ends of rotating ring one and rotating ring two respectively, blocking block one and blocking block two are fitted, and on the fixed shaft, auxiliary push ring one and auxiliary push ring two are mounted and rotated up and down, respectively, on the corresponding end faces of rotating ring one and rotating ring two.

[0009] Furthermore, a transverse groove is provided on the second fixed rod, and a slider is fitted in the groove. The locking mechanism includes a knob that is rotated and fitted on the slider. A rotating column is symmetrically fixed on the knob. A collar is connected to the side of the rotating column through a reset component. A friction plate is symmetrically fitted on the end of the collar through a guide component. The end of the collar is hinged to the friction plate through a hinge rod. A friction block is provided at the outer end of the friction plate.

[0010] Furthermore, the reset component includes a pull rope wound around the rotating column, the outer end of which is connected to a collar, and a reset spring is connected between the rotating column and the collar.

[0011] Furthermore, the pushing member includes a rotating groove formed at the crossbar connecting end of the second fixed rod, a telescopic member is fitted inside the rotating groove, and rollers are fitted at both ends of the telescopic member, and the rollers are matched and rolled in the connecting groove.

[0012] Furthermore, the telescopic component includes a telescopic sleeve connected between adjacent rollers, and a second spring is fitted inside the telescopic sleeve.

[0013] Furthermore, a barrier block is provided at the insertion end of the connecting slot to prevent the roller from accidentally coming off.

[0014] The beneficial effects of this invention are:

[0015] 1. This invention, by setting a switching mechanism, allows the wheels inside the base to be switched out. Simultaneously, a limiting component restricts the pedal and wheels, preventing them from retracting into the base under force, thus achieving the effect of ejecting the wheels. The wheels allow for easier movement of the perimeter fence, facilitating its transport and simplifying the work process. When the perimeter fence reaches its position and needs to be secured, the pedal is depressed via the switching mechanism, causing the wheels to retract into the base. Pressing down the push-pull handle moves the connecting column downwards. When the drill bit reaches a certain depth, the push-pull handle is quickly pulled upwards. Under the elastic connection of the spring element, the connecting column and drill bit undergo a certain degree of relative displacement. The spring element then pulls the drill bit back to its original position. As the drill bit rises, it pushes the protrusion on the auxiliary insertion rod, causing it to open outwards and embed itself into the surrounding moist soil. The auxiliary insertion rod assists in rooting and securing the drill bit, thereby improving the fixation effect between the fixing device and the ground.

[0016] 2. This invention, by setting a first fixed rod, a second fixed rod, and a splicing and merging unit, allows the first and second fixed rods to rotate and extend, enabling them to fix edge fences of different sizes and improving ease of handling. During connection, the two crossbars are inserted into each other and stably abutted together by a pushing member, allowing the first and second fixed rods to form a single unit. Simultaneously, rotating the knob pulls the collar inward via a reset member, and with the cooperation of the hinge rod, pulls the upper and lower friction plates and friction blocks to tighten, moving the locking mechanism to the designated position where the two crossbars intersect. Releasing the knob causes the upper and lower friction blocks to expand outward via the reset member, supporting the inside of the connecting groove and achieving a locking effect. After the splicing and merging unit is combined, it can be further locked by a locking mechanism, improving the stability of the connection between the first and second fixed rods. The splicing and merging unit allows for convenient connection of the two, and combined with the fixing effect of the base, it enhances the versatility and flexibility of the edge fence.

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] Please see Figure 1-7 This invention provides a technical solution for a perimeter fencing fixing device used in steel structure construction:

[0027] Example 1:

[0028] according to Figure 1 and Figure 2 As shown, the device includes left and right bases 1, with L-shaped first fixing rods 2 and second fixing rods 3 vertically mounted on each base 1. The first fixing rods 2 and 3 are composed of a vertical rod 21 mounted on the base 1 and a horizontal rod 22 hinged to the upper end of the vertical rod 21. The first fixing rods 2 and 3 are telescopic and rotatable, saving space when moved for storage. Furthermore, the two horizontal rods 22 can be joined together by splicing and merging units 5 at the ends of the first fixing rods 2 and 3, forming a U-shaped structure to facilitate the fixing of the edge fence. Figure 3As shown, a switching mechanism 4 is provided inside the base 1 to switch the fixing device to a state that facilitates movement or fixation. A pedal 41 is vertically slidably mounted inside the base 1, and a movable component 45 is also vertically slidably mounted inside the base 1. The movable component 45 is located behind the pedal 41, and a wheel 47 is connected to the lower part of the movable component 45 via an extension arm 46. A pushing component is provided between the pedal 41 and the movable component 45 to control their relative movement. During use, the edge fence fixing rod itself has a certain weight, making it difficult for operators to move. Furthermore, after the edge fence is assembled, the increased gravity makes moving it even more difficult. The switching mechanism 4 and the pushing component can control the wheel 47 to move downwards, switching the fixing device to a state that facilitates movement, thus allowing workers to move the edge fence more easily and effortlessly. Moving the wheel 47 upwards allows it to leave the ground, enabling the fixing device to be switched to a state that facilitates fixing. A rotating block 43 is rotatably mounted inside the base 1, located above the pedal 41 and the moving part 45. A movable rod 42 is hinged to the front end of the rotating block 43, and the lower end of the movable rod 42 is hinged to the top of the pedal 41. A movable rod 44 is hinged to the rear end of the rotating block 43, and the lower end of the movable rod 44 is hinged to the moving part 45. Lifting the pedal 41 causes the movable rod 42 to move upwards, while simultaneously forcing the rotating block 43 to rotate, thereby pressing down the movable rod 44. The moving part 45 connected to the movable rod 44 begins to descend, causing the extension arm 46 and the wheel 47 to descend as a whole, so that the wheel 47 contacts the ground. The fixing device can then be easily moved by the wheel 47. A limiting component 49 is provided inside the base 1 to position the pedal 41 vertically.

[0029] like Figure 4As shown, a fixing mechanism 48 for inserting and fixing the fixing device to the ground is provided in the base 1. A connecting post 481 is vertically and symmetrically slidably mounted in the base 1. A drill bit 482 is vertically and slidably mounted on the lower end of the connecting post 481. The surface of the pedal 41 has symmetrically opened insertion holes corresponding to the drill bit 482. The drill bit 482 is vertically inserted into the insertion holes. A push-pull handle 7 is fixedly mounted on the upper end of the connecting post 481 and is movably mounted on the upper part of the base 1. A fixing device 6 is provided on the base 1 to position the push-pull handle 7. When the pedal is pressed... When plate 41 is in the upper position, the position of push-pull handle 7 can be positioned by fixing device 6. Pushing and pulling handle 7 simultaneously puts drill bit 482 and pedal 41 in the upper position. Connecting post 481 and drill bit 482 are connected by elastic element 483, which can be a first spring. Through the elastic force of the first spring, a certain telescopic buffer space can be provided between connecting post 481 and drill bit 482. Auxiliary insertion rod 484 is circumferentially hinged to the side of drill bit 482, and the hinge point is located at the lower end of auxiliary insertion rod 484. The lower end of the auxiliary rod 484 has a protrusion on its inner side. A slot corresponding to the auxiliary rod 484 is circumferentially opened on the side wall of the connecting post 481. The protrusion of the auxiliary rod 484 is movably fitted into the slot. When the fixing device is inserted into the ground, the pedal 41 is in the lower position. Releasing the fixing of the push-pull handle 7 and pressing it downwards moves the connecting post 481 downwards. In wet conditions, the drill bit 482 can be directly pressed to drill into the ground. When a certain depth is reached, it is quickly pulled upwards. Due to the inertia of the first spring, the connecting post 481... The connecting post 481 and the drill bit 482 have a certain degree of relative displacement and separation. Then, the elastic force of the first spring pulls the drill bit 482 back to its original position. During the upward process, the drill bit 482, with the cooperation of the slot, can push the protrusion on the auxiliary insertion rod 484, causing the auxiliary insertion rod 484 to rotate around the hinge point and open outward. When the auxiliary insertion rod 484 opens, it will be blocked by the connecting post 481, which limits its opening range. When it is necessary to retract the drill bit 482, the push-pull handle 7 can be pressed down to force the auxiliary insertion rod 484 to close and then slowly pull it upward.

[0030] In practical use, the edge fence fixing device of the present invention for steel structure construction is used as follows: First, the pedal 41 is raised, which drives the first movable rod 42 to move upward. At the same time, the rotating block 43 is forced to rotate and press down the second movable rod 44. The second movable rod 44 pushes the moving part 45 to start descending, which drives the extension arm 46 and the wheel 47 to descend as a whole. The wheel 47 in the base 1 is switched out through the switching mechanism 4. The first fixing rod 2 and the second fixing rod 3 are moved to the positions that need to be fixed. When the edge fence reaches the position and needs to be fixed, the pedal 41 is pressed down through the switching mechanism 4, the wheel 47 retracts into the base 1, and then the restraint of the fixing device 6 on the push-pull handle 7 is released. The push-pull handle 7 is then pressed down. The connecting column 481 moves downwards. When in wet conditions, the drill bit 482 can be pressed directly into the ground. When it reaches a certain depth, it is pulled upwards quickly. Due to inertia, the connecting column 481 and the drill bit 482 separate to a certain extent. The first spring pulls the drill bit 482 back to its original position. The drill bit 482 pushes the protrusion on the auxiliary rod 484, causing it to open outwards. The auxiliary rod 484 rotates on the rotating rod. When it opens, it is blocked by the connecting column 481, which limits its opening range. When retracting the fixing device, it can be pressed downwards to force the auxiliary rod 484 to close and then slowly pull it upwards. For hard ground, it is necessary to drill holes beforehand and insert it. After opening, the pedal 41 blocks its upward movement, achieving the effect of rooting and fixing.

[0031] Example 2:

[0032] Based on Example 1, such as Figure 5As shown, the limiting component 49 includes a fixed shaft 491 vertically fitted inside the bottom of the base 1. Rotating ring 1 492 and rotating ring 2 495 are symmetrically mounted on the fixed shaft 491. A blocking block 1 493 is fitted to the outer end of rotating ring 1 492, and a blocking block 2 496 is fitted to the outer end of rotating ring 2 495. Auxiliary push ring 1 494 and auxiliary push ring 2 497 are correspondingly mounted on the fixed shaft 491 at their respective end faces. The outer ends of auxiliary push ring 1 494 and auxiliary push ring 2 497 overlap with rotating ring 2 495 and rotating ring 1 492, respectively. When the pedal 41 moves downwards, the blocking block 1 493 can be pushed outwards due to compression. At this time, rotating ring 1 492 connected to the blocking block 1 493 will push the auxiliary push ring 1 494. When the auxiliary push ring 494 is driven, the other end of it generates a thrust on the rotating ring 495. The blocking block 496, which is rotatably connected to the rotating ring 495, will move inward, and vice versa. This limits the two states of the pedal 41, allowing the switching mechanism 4 and the limiting component 49 to work together to retract and extend the wheel 47. By setting the limiting component 49, the wheel 47 can be moved out of the base 1 and limited and fixed, preventing it from retracting back into the base 1 due to force. The wheel 47 facilitates the transport of multiple edge fences at one time while saving effort. Both the blocking block 493 and the blocking block 496 are fixedly connected to plates on the outside. When they get stuck or need to be replaced manually, they can be pushed from the outside to change the locking position, or the external plates can be fixed for stronger fixation, resulting in a better blocking effect.

[0033] Example 3:

[0034] Based on Example 1, such as Figure 5As shown, a connecting groove 55 is laterally opened at the end of the crossbar 22 of the first fixed rod 2. The corresponding end of the crossbar 22 of the second fixed rod 3 is slidably fitted into the connecting groove 55. The splicing unit 5 includes a pushing member provided at the outer end of the crossbar 22 of the second fixed rod 3. A rotating groove is opened at the connecting end of the crossbar 22 of the second fixed rod 3. A telescopic member is fitted in the rotating groove. The telescopic member is a telescopic sleeve 54. A second spring 53 is fitted in match inside the telescopic sleeve 54. Rollers 52 are rotatably fitted at both ends of the telescopic sleeve 54. The rollers 52 are rolled in the connecting groove 55 on the surface of the crossbar 22 of the first fixed rod 2. Through the telescopic elastic force of the telescopic member, the rollers 52 can abut against the inner wall of the connecting groove 55. The pushing member makes the second fixed rod 2 crossbar 22... The connecting end of the fixed rod 3 is stably abutted in the connecting groove 55. When the roller 52 rolls inside the connecting groove 55, due to the elasticity of the telescopic component, it can adapt to the different distances of the connecting grooves 55 of the first fixed rod 2. At the same time, the telescopic component is set in the rotating groove inside the second fixed rod 3, and both ends of the telescopic component are provided with protrusions that abut against the ends of the rotating groove, so that the shortest retracted length of the telescopic component is limited, and the two will not be separated due to the action of the second spring 53. At the insertion end of the connecting groove 55, there is an obstacle block 51 to prevent the roller 52 from accidentally coming out. The obstacle block 51 can limit and block the two rollers 52 in the free state, preventing the rollers 52 from coming out of the connecting groove 55 on their own without the action of external force.

[0035] In practical use, the edge fence fixing device of the present invention for steel structure construction, when in use, the pusher fixed at the front end of the second fixing rod 3 passes through the obstacle block 51 and enters the connecting groove 55 of the first fixing rod 2. When the roller 52 rolls inside the connecting groove 55, under the elastic force of the telescopic member, it can adapt to the change of the distance between the two first fixing rods 2. The first fixing rod 2 and the second fixing rod 3 can be connected by the splicing and merging unit 5. When the first fixing rod 2 fixes one edge fence and the second fixing rod 3 fixes the second one, the movement of the splicing and merging unit 5 can match the two edge fences and adjust the size of the edge fences. It is suitable for situations where the blocking range of one fence is insufficient and the blocking range of two fences is too large. At the same time, with the fixing effect of the base 1, the versatility of the edge fence is improved.

[0036] Example 4:

[0037] Based on Example 3, such as Figure 7As shown, a locking mechanism 56 is provided on the crossbar 22 of the second fixed rod 3 to provide a limiting function in cooperation with the crossbar 22 of the first fixed rod 2. A sliding groove is provided laterally on the second fixed rod 3, and a slider 560 is fitted in the sliding groove. A knob 561 is vertically rotatably mounted on the slider 560. A rotating column 562 is symmetrically fixed on the knob 561. A transverse collar 565 is connected to the side of the rotating column 562 through a reset component. The reset component can be a structure with various retraction and reset functions, such as a pull rope 563 wound on the rotating column 562. The outer end of the pull rope 563 is connected to the collar 565, and a reset spring 564 is connected between the rotating column 562 and the collar 565. A guide kit 567 is provided vertically at the end of the collar 565. Friction plates 568 are symmetrically slidably mounted in the guide kit 567, and the end of the collar 565 is connected to the friction plates 568 through a hinge rod 566. The surfaces of the friction plates 568 are hinged, and friction blocks 569 are provided at the outer ends of each friction plate 568. When the two crossbars 22 are connected to each other, the knob 561 is rotated, the knob 561 tightens the pull rope 563, the pull rope 563 pulls the collar 565 to move inward, the collar 565 pulls the hinge rod 566 to move. Under the guidance of the guide kit 567, the hinge rod 566 can pull the two friction plates 568 to move towards the center. At this time, the upper and lower friction blocks 569 are retracted. Then, the crossbar 22 of the second fixed rod 3 is moved to the inside of the crossbar of the first fixed plate. The knob 561 is released, the return spring 564 pushes the collar 565, so that the upper and lower friction plates 568 drive the friction blocks 569 to expand outward, supporting the inside of the connecting groove 55 of the first fixed rod 2, achieving the locking effect. Moreover, the movement of the slider 560 can move the locking mechanism 56 on the groove of the second fixed rod 3 to the required place for locking.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
