Description

Technical Field

[0001] The invention relates to the technical field of cantilever scaffolding, in particular to a detachable bottom-supporting I-beam cantilever scaffolding device. Background Art

[0002] At present, I-beam cantilever scaffolding is widely used in the construction industry. Especially in the construction process of some medium and high-rise buildings, it is often necessary to set up I-beam cantilever scaffolding with a height of more than 20 meters. The traditional method usually requires pre-embedded steel plates in the wall or beam body, and then the lower support rods are fixedly connected to the main beam by welding. However, this method is not only easy to damage the main beam structure, but also has great safety hazards, and has high requirements for the positioning accuracy of the pre-embedded steel plates and the welding process level.

[0003] In addition, the installation and removal process of the cantilever beam's lower support rod is cumbersome, time-consuming and labor-intensive, which brings great inconvenience to the construction. If only bolts are used for simple fixing, when the force is too large, the bolt connection position is prone to loosening or even displacement, resulting in a significant reduction in the support effect. Once the lower support rod is displaced, the support system of the entire scaffolding will be seriously affected and there is a risk of collapse at any time. What's more serious is that this safety hazard is often difficult to detect in time, and it is impossible to issue timely and effective warnings to on-site construction personnel, which further exacerbates the safety risks.

[0004] Therefore, it is of great significance to study a new detachable bottom-supported I-beam cantilever scaffolding device to solve the above problems. Summary of the invention

If only bolts are used for simple fixing, when the force is too large, the bolt connection position is prone to loosening or even displacement, and this safety hazard is often difficult to detect in time, and it is even more difficult to issue timely and effective warnings to on-site construction personnel, which further aggravates the problem of safety risks.

[0043] Example 1

[0044] like Figure 1-Figure 11As shown, the present invention provides a technical solution: a detachable bottom-supported I-beam cantilever scaffolding device, comprising an I-beam erection mechanism 200, the I-beam erection mechanism 200 is assembled on a structural beam 100, and the I-beam erection mechanism 200 is equipped with a support and automatic locking mechanism 300;

[0045] The I-beam erection mechanism 200 includes a plurality of adjustable lower support assemblies 201, and the adjustable lower support assembly 201 includes a mounting member 2012 and a lower support member 2011. The mounting member 2012 is mounted on the structural beam 100 by a first bolt 2013. The mounting member 2012 can be mounted on the structural beam 100 by the first bolt 2013, so that one end of the lower support member 2011 can be locked, so that the lower support member 2011 can provide a lower support point through the mounting member 2012, and the lower support member 2011 can be adjusted to the tooth groove of the latch plate 2021 by a pin shaft, so as to support the I-beam 2022. This method satisfies the construction requirements of rapid disassembly and assembly, reduces the construction difficulty, and avoids damage to the I-beam 2022 by welding. The mounting member 2012 is hinged to the lower support member 2011 by a pin shaft. An I-beam clamping assembly 202 is provided at one end of the adjustable lower support assembly 201, and the I-beam clamping assembly 202 includes a latching gear The lower support member 2011 is engaged with the tooth groove of the latch plate 2021. The latch plate 2021 is provided with a plurality of tooth grooves, so that the lower support member 2011 is engaged with different tooth grooves, and the lower support angle can be adjusted, making the construction more flexible. Moreover, the lower support member 2011 is engaged with the tooth groove of the latch plate 2021, so as to lock the position of the latch plate 2021 and prevent the latch plate 2021 from sliding, so that the latch plate 2021 can smoothly support the I-beam 2022. The lower support member 2011 is provided with two first clamping plates 2023 on top thereof, and an I-beam 2022 is arranged on top of the lower support member 2011. The I-beam 2022 is placed on the structural beam 100. The two first clamping plates 2023 are locked on the I-beam 2022 by second bolts 2024. The first clamping plates 2023 can be locked on the I-beam 2022 by the second bolts 2024, so as to ensure the firmness of the connection and prevent sliding from affecting the lower support effect.

[0046] The support and automatic locking mechanism 300 includes a plurality of telescopic components 301 and a plurality of fixed components 302. The fixed components 302 include a bottom plate 3022. The top of the bottom plate 3022 overlaps the I-beam 2022. Two second clamping plates 3021 are fixedly connected to the top of the bottom plate 3022. The two second clamping plates 3021 are locked on the I-beam 2022 by third bolts 3023. The second clamping plates 3021 can be tightened by the third bolts 3023 so that the second clamping plates 3021 can be locked on the I-beam 2022, thereby maintaining the firmness of the support and automatic locking mechanism 300 and preventing sliding and dragging, so that the support and automatic locking mechanism 300 can smoothly achieve the supporting effect, and the first clamping plates 2023 and the second clamping plates 30 A rubber pad can be added to the side of the I-beam 2022 that fits the I-beam 2022, so that the firmness of the connection can be increased by deforming the rubber pad, and it is not easy to cause damage to the I-beam 2022. A plurality of telescopic components 301 connect the fixed components 302 together, and the fixed components 302 are connected to the I-beam clamping components 202. Two locking components 304 are arranged on both sides of the fixed components 302. The locking components 304 include nuts 3044, which are fixedly mounted on the second clamping plate 3021. The internal threads of the nuts 3044 are connected to the screw rod 3041. The two ends of the screw rod 3041 are respectively fixedly connected to the locking blocks 3043 and the gears 3042. The screw rod 3041 and the nut 3044 can be operated by the gears 3042 to move between the screw rod 3041 and the nut 3044. The screw drive causes the screw rod 3041 to drive the locking block 3043 to move, so that the locking block 3043 can be pre-tightened on the I-beam 2022, increasing the connection points, thereby increasing the tightness of the connection. The locking block 3043 is overlapped on the I-beam 2022, and the two locking components 304 are transmitted with the hydraulic transmission component 305. The hydraulic transmission component 305 includes a round shell 3051, and the round shell 3051 is fixedly connected to the second clamping plate 3021. One side of the round shell 3051 is connected with a cylindrical barrel 3055. The round shell 3051 is connected with the cylindrical barrel 3055, so that the liquid stored in the cylindrical barrel 3055 and the round shell 3051 can circulate between the two. A piston rod 3054 is arranged inside the cylindrical barrel 3055, and one end of the piston rod 3054 passes through The cylindrical barrel 3055 is provided with a sealing plug 3052, and the upper and lower sides of the two-way gear rod 3056 correspond to the two gears 3042. The two-way gear rod 3056 can be displaced to transmit the transmission to the gear 3042, thereby providing a rotational force for the screw rod 3041, so that the screw rod 3041 can rotate to drive the locking block 3043 to apply a force to the I-beam 2022, thereby increasing the stability of the first splint 2023 and preventing the first splint 2023 from being displaced. The circular shell 3051 is provided with a sealing plug 3052. The sealing connection between the sealing plug 3052 and the piston rod 3054 and between the circular shell 3051 and the cylindrical barrel 3055 can make the sealing plug 3052 movable by hydraulically driving the piston rod 3054 to move.A second spring 3053 is fixedly connected between the sealing plug 3052 and the side wall of the round shell 3051, and the position of the sealing plug 3052 can be maintained by the second spring 3053. A switch 3057 is fixedly installed on one side of the sealing plug 3052, and the alarm 3033 can be controlled by the switch 3057 to achieve the purpose of alarm. A hydraulic drive component 303 is penetrated by the hydraulic transmission component 305, and the hydraulic drive component 303 includes a hole sleeve 3031, which is fixedly connected to the first clamping plate 2023. A driving rod 3032 is fixedly passed through the hole sleeve 3031, and an alarm 3033 is fixedly installed on one end of the driving rod 3032. The other end of the driving rod 3032 penetrates the round shell 3051 and passes through the sealing plug 3052. The part of the driving rod 3032 passing through the sealing plug 3052 is sealed to prevent the liquid from flowing into the left inner cavity of the round shell 3051. A first spring 3034 is fixedly connected between the end of the driving rod 3032 passing through the sealing plug 3052 and the sealing plug 3052. The driving rod 3032 can be connected to the sealing plug 3052 through the first spring 3034, and the elastic force of the first spring 3034 is much greater than the elastic force of the second spring 3053, so that the movement of the driving rod 3032 can smoothly drive the sealing plug 3052 to move in advance through the first spring 3034. A contact block 3035 is fixedly connected to the driving rod 3032, and the upper part of the contact block 3035 corresponds to the position of the switch 3057. The hydraulic driving assembly 303 is connected to the I-beam clamping assembly 202.

[0047] In this embodiment, by connecting the hydraulic drive assembly 303 to the first clamping plate 2023, the movement of the first clamping plate 2023 can drive the sealing plug 3052 to move through the driving rod 3032, so that the sealing plug 3052 can be moved by the hydraulic driving piston rod 3054 and the two-way gear rod 3056, and the two-way gear rod 3056 is transmitted with the gear 3042, so that the gear 3042 gives the screw rod 3041 a rotational force, so that the screw 3041 can control the locking block 3043 to apply a clamping force to the I-beam 2022, thereby effectively preventing the problem of slippage. The automatic locking method can effectively improve the safety of construction. At the same time, if the slippage continues, the driving rod 3032 can drive the contact block 3035 to move alone, so that the contact block 3035 touches the pressure switch 3057, so that the purpose of alarm can be achieved through the alarm 3033, so that the on-site construction personnel can be warned in the first time, which is convenient for the construction personnel to quickly evacuate the dangerous area, thereby greatly reducing the safety risk.

Secondly, by connecting with the same span, a more stable structure can be formed. This connection can effectively reduce the safety hazards of tilting and shaking of the I-beam erection mechanism 200 during use, and improve the overall stability. The connected support and automatic locking mechanism 300 can share the load together and maintain force uniformity, thereby improving the load-bearing capacity of the entire system.

[0051] Example 3

[0052] Combination Figure 3 and Figure 5 It is concluded that the support and automatic locking mechanism 300 includes a plurality of telescopic components 301 and a plurality of fixed components 302. The plurality of telescopic components 301 connect the fixed components 302 together, and the fixed components 302 are connected to the I-beam clamping components 202. Two locking components 304 are arranged on both sides of the fixed components 302.

[0053] In this embodiment: by connecting the telescopic component 301 with the fixed component 302, and the fixed component 302 is also connected to the I-beam clamping component 202, the telescopic component 301 is connected to the I-beam clamping component 202 through the fixed component 302, which not only can improve the bearing capacity of the I-beam 2022, but also the three are integrated to avoid carrying more parts and construction tools separately for construction, which can not only reduce the construction burden of construction personnel, but also facilitate safe construction operations, and at the same time avoid the risk of parts and construction tools falling from high altitudes, further improving safety.

[0054] The working principle of the present invention is as follows: after the I-beam 2022 is installed, the installation position of the lower support member 2011 is determined below the I-beam 2022, and the installation member 2012 is fixed to the structural beam 100 by the first bolt 2013;

[0055] After the lower support 2011 is installed, the tooth plate 2021 is adjusted to a proper position according to the lower support 2011, and the first clamping plate 2023 is clamped and fixed on the I-beam 2022 using the second bolt 2024, and the lower support 2011 is lifted up so that the lower support 2011 is clamped on the tooth groove of the tooth plate 2021 to form a return top force;

[0056] Then, the second clamping plate 3021 is fixed to the end of the I-beam 2022 by the third bolt 3023, and the gear 3042 is rotated at the same time, so that the gear 3042 drives the screw rod 3041 to rotate, and the screw rod 3041 drives the locking block 3043 to be pre-tightened on the side of the I-beam 2022, thereby completing the installation;

[0057] When the first clamping plate 2023 is subjected to external force, the first clamping plate 2023 applies force to the sealing plug 3052 through the driving rod 3032, and the sealing plug 3052 presses the liquid into the cylindrical tube 3055, and the piston rod 3054 is driven to move by hydraulic pressure, and the piston rod 3054 drives the two-way gear rod 3056 to move, and the two-way gear rod 3056 and the gear 3042 are driven, so that the gear 3042 applies a rotational force to the screw rod 3041, and then the locking block 3043 applies pressure to the I-beam 2022, thereby effectively preventing the risk of slippage;

[0058] After the sliding distance of the first clamping plate 2023 increases, the sealing plug 3052 moves to the maximum limit. At this time, the driving rod 3032 overcomes the elastic force of the first spring 3034, and the driving rod 3032 drives the contact block 3035 to move.
