[0031] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0032] Combine the following Figures 1 to 11 , describing an embodiment of the utility model.

[0033] In the first aspect, the utility model provides a cantilever work platform, including a first support beam 2, a platform board 3 and a guardrail 4. Specifically, two first support beams 2 are arranged at intervals, and the first support beam 2 includes a fixed section 21 and a cantilever section 22. The fixed section 21 is detachably connected to the structural layer 1, and the cantilever section 22 is arranged outside the structural layer 1. The cantilever section 22 is provided with a limiting groove 221 and a limiting column 222. The platform board 3 includes a pedal portion 31 and a support portion 32. The support portion 32 is suitable for supporting the pedal portion 31, and along the spacing direction of the two first support beams 2, the two ends of the support portion 32 are respectively engaged with the limiting grooves 221 of the two first support beams 2. The guardrail 4 is arranged around the periphery of the pedal portion 31, and the bottom of the guardrail 4 is provided with an opening, and the bottom of the guardrail 4 is sleeved on the limiting column 222.

[0034] It should be noted that structural layer 1 refers to the installation foundation of the cantilever work platform, such as a floor slab.

[0035] By adopting the technical solution of the utility model, the fixed section 21 of the first support beam 2 is detachably connected to the structural layer 1, and the two ends of the support part 32 of the platform plate 3 are respectively clamped in the limiting groove 221, so that the platform plate 3 can be detachably installed on the cantilever section 22 of the first support beam 2, and the bottom of the guardrail 4 is sleeved on the limiting column 222, so that the guardrail 4 can be detachably installed on the cantilever section 22 of the first support beam 2, and the guardrail 4 is arranged around the periphery of the pedal part 31, and an opening is provided at the bottom to match the pedal part 31.

[0036] Therefore, the utility model sets three components, namely, the first support beam 2, the platform plate 3 and the guardrail 4, and assembles the three components into a cantilever work platform and arranges it on the structural layer 1 through a detachable connection method. The weight of each component is greatly reduced compared to the entire cantilever work platform, and it can be completed manually without the need for hoisting equipment, and is not restricted by height or space, so the installation and disassembly flexibility is higher. And through the limit groove 221 and the limit column 222 of the cantilever section 22, the first support beam 2 is assembled with the platform plate 3 and the guardrail 4, and the installation and disassembly are convenient. In addition, the cantilever work platform of the utility model facilitates the standardization or modularization of components, which is conducive to rapid operation at the construction site.

[0037] The technical solution of the utility model is described below in conjunction with Embodiment 1 and Embodiment 2.

[0038] Embodiment 1

[0039] See also Figures 1 to 4 , Figures 7 to 11 ,in, Figures 1 to 4 The structure diagram of the cantilever work platform of the first embodiment is shown. Figures 7 to 11 A structural schematic diagram of the cantilever work platform installation process of the first embodiment is shown.

[0040] In this embodiment, two first support beams 2 are arranged at intervals, and the first support beams 2 include a fixed section 21 and a cantilever section 22. The fixed section 21 is detachably connected to the structural layer 1, and the cantilever section 22 is arranged outside the structural layer 1. The cantilever section 22 is provided with a limiting groove 221 and a limiting column 222. The platform plate 3 includes a pedal portion 31 and a support portion 32. The support portion 32 is suitable for supporting the pedal portion 31, and along the spacing direction of the two first support beams 2, the two ends of the support portion 32 extend out of the pedal portion 31 to be respectively engaged with the limiting grooves 221 of the two first support beams 2. The guardrail 4 is arranged around the outer periphery of the pedal portion 31, and the bottom of the guardrail 4 is provided with an opening, and the bottom of the guardrail 4 is sleeved on the limiting column 222.

[0041] Further, such as Figure 2 As shown, the limiting groove 221 is arranged at the top of the cantilever section 22, and the opening faces upward, so as to facilitate the installation of the platform plate 3 above the first support beam 2, thereby further improving the convenience of installation and disassembly.

[0042] Specifically, each first support beam 2 is provided with two limiting grooves 221 at intervals, and the support portion 32 includes two second support beams 321 arranged at intervals, and both ends of the second support beams 321 extend out of the pedal portion 31 and form a first clamping portion 3211. The first clamping portions 3211 of the two second support beams 321 located on the same side are respectively clamped with the two limiting grooves 221 of one of the first support beams 2. In this arrangement, the two ends of the two second support beams 321 are respectively clamped with the two limiting grooves 221 of the two first support beams 2, and the limiting grooves 221 of the two first support beams 2 form four support points on both sides of the platform plate 3, which has higher stability and reliability in installation.

[0043] Among them, the setting size and internal contour of the limiting groove 221 depend on the setting size and internal contour of the first clamping part 3211, and the utility model does not make specific restrictions on this. It should be noted that in the direction perpendicular to the spacing of the two first support beams 2, that is, in the extension direction of the first support beam 2, the setting size of the limiting groove 221 is close to the setting size of the first clamping part 3211, or the setting size of the limiting groove 221 is slightly larger than the setting size of the first clamping part 3211, so as to prevent the second support beam 321 from moving in the extension direction of the first support beam 2. The internal contour of the limiting groove 221 can be the same as or different from the external contour of the first clamping part 3211, as long as the first clamping part 3211 can enter the limiting groove 221 from the opening of the limiting groove 221. Exemplarily, the first clamping part 3211 is formed at both ends of the steel pipe, and its external contour is a circular arc tubular structure. Correspondingly, the internal contour of the clamping groove can be a circular arc groove structure or a right angle groove structure.

[0044] For further information, see Figure 3 , first stoppers 322 are also provided at both ends of the second support beam 321. The first stoppers 322 are located outside the first clamping portion 3211. Along the spacing direction of the two first support beams 2, the first stoppers 322 are located outside the stopper groove 221, and the setting size of the first stoppers 322 is larger than the outer opening size of the stopper groove 221. In the spacing direction of the two first support beams 2, the first stoppers 322 can limit the movement of the second support beam 321, prevent the second support beam 321 from separating from the first support beam 2, and increase the safety and reliability of the structure.

[0045] For further information, see Figure 2 The second limiting member 23 is welded on the top of the cantilever section 22. The second limiting members 23 are arranged in pairs, and the limiting groove 221 is formed between the second limiting members 23 arranged in pairs. The second limiting member 23 is welded on the top of the cantilever section 22 to form the limiting groove 221, which does not destroy the original structure of the first support beam 2, ensures the structural strength of the first support beam 2, and further increases the safety and reliability of the structure.

[0046] In this embodiment, two pairs of second limit members 23 are welded on each first support beam 2, and the two pairs of second limit members 23 are arranged at intervals along the extension direction of the first support beam 2 to form the above-mentioned two limit grooves 221. In some embodiments not shown in the figures, the number of second limit members 23 can also be one pair, three pairs or other numbers, which is not specifically limited in the present invention.

[0047] Exemplarily, the first support beam 2 and the second support beam 321 may both be steel pipes or I-beams. Preferably, the first support beam 2 is an I-beam, and the second support beam 321 is a steel pipe.

[0048] Exemplarily, the first position-limiting member 322 may be a steel plate welded to both end surfaces of the second support beam 321 in the length direction, or the first position-limiting member 322 may be integrally formed with the second support beam 321 .

[0049] Exemplarily, the second limiting member 23 may be a steel plate or an angle steel, etc., which has high structural strength and low cost.

[0050] Further, in this embodiment, the pedal portion 31 may be an integral rigid structure, and in a direction perpendicular to the spacing between the two first support beams 2, that is, in the extension direction of the first support beams 2, the two second support beams 321 are located at both ends of the pedal portion 31 and are welded to the bottom of the pedal portion 31. Exemplarily, the pedal portion 31 may be a steel plate.

[0051] In this embodiment, the platform plate 3 further includes a handle portion 33, which is connected to the outer side of one of the second support beams 321. The handle portion 33 is suitable for driving the pedal portion 31 to rotate under the drive of an external force. Fig. 9 and 10 As shown, the first second support beam 321 with the handle portion 33 is first clamped into the two limiting grooves 221 near the side of the structural layer 1, and then the handle portion 33 is rotated, and the handle portion 33 drives the pedal portion 31 and the support portion 32 to rotate, so that the second second support beam 321 automatically falls into the two limiting grooves 221 away from the structural layer 1. In addition, the second second support beam 321 can be detached from the limiting groove 221 by rotating the handle portion 33 in the opposite direction. The platform board 3 arranged in this way further improves the convenience of installation and removal of the platform board 3 and the first support beam 2.

[0052] For example, see Figure 3 The handle part 33 is provided at both ends of the second support beam 321. The handle part 33 includes a handle body 331 and a handle sleeve 332. The handle body 331 and the handle sleeve 332 are detachably connected. When in use, the handle body 331 can be inserted into the handle sleeve 332. After use, the handle body 331 can be detached from the handle sleeve 332.

[0053] Exemplarily, the handle sleeve 332 may be welded to the outer side surface of the first limiting member 322 .

[0054] Exemplarily, the handle sleeve 332 and the handle body 331 may be square or round steel pipes or the like.

[0055] Further, such as Figure 2 As shown, each first support beam 2 is provided with a plurality of limit posts 222, and the bottom of the guardrail 4 is provided with a plurality of sockets corresponding to the plurality of limit posts 222, and the guardrail 4 is plugged into the limit posts 222 through the sockets to achieve a detachable connection between the guardrail 4 and the first support beam 2. Exemplarily, the limit posts 222 can be welded to the top of the first support beam 2.

[0056] In this embodiment, the guardrail 4 includes a column 41 and a guardrail net 42, wherein a plurality of columns 41 are provided and arranged on both sides of the guardrail net 42 in the height direction, and the bottom of each column 41 is formed with the above-mentioned socket, and the bottom of the column 41 is sleeved on the limit column 222 through the socket. It can be understood that the column 41 is a hollow tubular structure, which can be a square tube, a round tube or other structures.

[0057] Specifically, Figure 2 and Figure 4 As shown, a plurality of first connection holes 2221 are provided on the side of the limiting column 222, and correspondingly, a plurality of second connection holes 411 are provided on the bottom of the column 41. The column 41 is inserted into the limiting column 222 through a socket and is bolted through the first connection holes 2221 and the second connection holes 411.

[0058] In some embodiments not shown in the figures, the socket can also be set on the limiting column 222. It can be understood that the limiting column 222 is a hollow tubular structure, the bottom of the column 41 is inserted into the socket of the limiting column 222, and the two are bolted together through the first connecting hole 2221 and the second connecting hole 411.

[0059] In addition, the guardrail 4 can be an integral structure or a split structure. The use of a split guardrail 4 is beneficial to further reduce the weight of the component and improve the flexibility of installation and disassembly.

[0060] Exemplarily, the guardrail 4 includes a first part, a second part and a third part, wherein in the spacing direction of the two first support beams 2, the first part and the second part are arranged on both sides of the pedal part 31, and in the extension direction of the first support beam 2, the third part is arranged on the side of the pedal part 31 away from the structural layer 1.

[0061] Exemplarily, the first part, the second part and the third part each include two columns 41 and a guardrail net 42 welded between the two columns 41. Accordingly, the cantilever section 22 of each first support beam 2 is provided with three of the above-mentioned limit columns 222 to correspond to the six columns 41 of the guardrail 4, respectively.

[0062] Further, such as Figure 1 As shown, a plurality of anchors 11 are pre-embedded on the structural layer 1, and the fixing section 21 can be installed on the anchor 11 of the structural layer 1. In this embodiment, the cantilever work platform further includes a third connecting member 5, and the third connecting member 5 is threadedly matched with the anchor 11 to clamp and fix the fixing section 21 on the anchor 11, which is convenient for installation.

[0063] Exemplarily, a threaded section is provided at the top of the anchor 11 , and the third connecting member 5 includes a connecting plate and a nut. The connecting plate is provided with two connecting holes matching the anchor 11 , and the nut matches the threaded section of the anchor 11 .

[0064] During installation, the fixing section 21 is placed between the two anchors 11 , and the two connecting holes of the connecting plate are respectively sleeved on the two anchors 11 , and two nuts are respectively tightened on the threaded sections of the two anchors 11 above the connecting plate.

[0065] Exemplarily, a plurality of third connecting members 5 may be provided, and the plurality of third connecting members 5 are spaced apart along the extension direction of the fixed section 21 to ensure the stability of the installation of the cantilever work platform.

[0066] Combine the following Figures 7 to 11 , describing the installation process of the cantilever work platform of this embodiment:

[0067] Step 1: Prepare accessories

[0068] According to the force requirements and working conditions, the models of the components of the cantilever work platform are selected and processed to obtain the first support beam 2, the platform plate 3 and the guardrail 4;

[0069] Step 2: Pre-embedded anchor 11

[0070] like Figure 7 As shown, the number and spacing of anchors 11 required for installing the cantilever work platform are obtained according to the calculation results, and the anchors 11 are pre-buried in the structural layer 1. Alternatively, in some solutions, the existing anchors 11 can also be used to install the cantilever work platform.

[0071] Step 3: Install the first support beam 2

[0072] like Figure 8As shown, the two first support beams 2 are transported to the location to be installed, and the fixed section 21 of each first support beam 2 is manually placed in the anchor 11, the positions of the two first support beams 2 are adjusted, and then the third connecting member 5 is correspondingly fixed to the anchor 11 to complete the detachable connection of the two first support beams 2 on the structural layer 1.

[0073] Step 4: Install the platform board 3

[0074] like Fig. 9 As shown, the platform board 3 is moved to the two first support beams 2, and the first second support beam 321 with the handle portion 33 is inserted into the two limit grooves 221 close to the structural layer 1. At this time, the platform board 3 is in a vertical state and the handle is in a horizontal state.

[0075] like Fig.10 As shown, the handle portion 33 is rotated to a vertical state, at which time the handle portion 33 drives the platform plate 3 to flip to a horizontal state, and makes the second second support beam 321 fall into the limiting groove 221 away from the structural layer 1, completing the detachable connection between the platform plate 3 and the two first support beams 2.

[0076] Step 5: Install guardrail 4

[0077] The guardrail 4 is moved to the corresponding position, the columns 41 are correspondingly inserted into the limiting columns 222 , and are fastened and fixed by bolts to complete the detachable connection between the guardrail 4 and the two first support beams 2 .

[0078] After the cantilever work platform is used, it can be dismantled in the order of guardrail 4-platform board 3-first support beam 2, which will not be repeated here.

[0079] Embodiment 2

[0080] See also Figure 5 and Figure 6 , Figure 5 and Figure 6 A schematic structural diagram of the cantilever work platform of the second embodiment is shown.

[0081] The difference between this embodiment and the first embodiment is that the setting method of the limit groove 221 is different. In this embodiment, the limit groove 221 is set on the inner side of the cantilever section 22, and the opening faces the other first support beam 2. During installation, before the two first support beams 2 are fixed to the structural layer 1, the two ends of the support portion 32 of the platform plate 3 are first inserted into the limit groove 221, and then the first support beam 2 is fixed to the structural layer 1. In this way, the installation of the platform plate 3 can be completed in the structural layer 1, which increases the safety of the cantilever work platform assembly.

[0082] Further, in this embodiment, the limiting groove 221 is arranged at the end of the cantilever section 22 away from the fixed section 21, and the support part 32 includes a third support beam 323 and a first connecting member 324. Along the extension direction of the first support beam 2, the third support beam 323 and the first connecting member 324 are respectively arranged at the two ends of the pedal part 31. The two ends of the third support beam 323 extend out of the pedal part 31 and form a second clamping portion 3231, which is clamped with the limiting groove 221. The first connecting member 324 is suitable for being detachably connected to the structural layer 1. In the spacing direction along the two first support beams 2, the third support beam 323 supports the pedal part 31 through the second clamping portions 3231 at both ends, and in the extension direction along the first support beam 2, the first connecting member 324 and the third support beam 323 respectively support the pedal part 31 at both ends of the pedal part 31 to ensure the safety and reliability of the structure.

[0083] like Figure 5 and Figure 6 As shown, in this embodiment, a third stopper 24 is welded to the end of the cantilever section 22 away from the fixed section 21, and the stopper groove 221 is formed between the third stopper 24 and the outer end surface of the cantilever section 22. Exemplarily, the third stopper 24 can be a triangular steel plate, an I-beam section or a steel pipe.

[0084] Exemplarily, the third support beam 323 may be a steel pipe or an I-beam, etc., and the first connecting member 324 may be a hanging ring, a steel bar segment with a hook, etc.

[0085] Furthermore, in this embodiment, the pedal portion 31 includes a plurality of sub-pedals 311 and a plurality of second connecting members 312. The plurality of sub-pedals 311 are sequentially arranged along the extension direction of the first support beam 2, and the second connecting members 312 are rotatably connected between adjacent sub-pedals 311; the third support beam 323 and the first connecting member 324 are respectively arranged on one of the sub-pedals 311 at the head and tail ends. The plurality of sub-pedals 311 can be relatively rotated by the second connecting member 312, and then folded or flattened, that is, in this embodiment, the pedal portion 31 is a foldable structure.

[0086] Exemplarily, the second connecting member 312 may be a hinge, connected between two adjacent sub-pedals 311 to achieve the rotational connection of the two sub-pedals 311. Exemplarily, the second connecting member 312 includes a connecting rod and a first connecting portion and a second connecting portion coaxially rotatably connected to the connecting rod, and the first connecting portion and the second connecting portion are respectively connected to the two adjacent sub-pedals 311.

[0087] In this embodiment, the cantilever section 22 is further provided with a slide groove 223, which is arranged on the inner side of the limiting groove 221 and extends toward the fixed section 21. The second connecting member 312 is arranged in parallel with the third support beam 323, and pulleys 3121 are arranged at both ends of the second connecting member 312 located in the middle, and the pulleys 3121 are movably arranged in the slide groove 223. The pulleys 3121 are arranged to facilitate the unfolding or folding of the pedal part 31. In this embodiment, the first support beam 2 is made of I-beam, and the slide groove 223 is formed on the inner side of the I-beam without additional processing. Exemplarily, the pulleys 3121 can be arranged at both ends of the above-mentioned connecting rod.

[0088] It is understandable that in some embodiments not shown in the figures, the platform plate 3 of this embodiment can also adopt the same structure as the platform plate 3 in embodiment 1. In addition, in this embodiment, the structure of the limit column 222 and the guardrail 4 is basically the same as that in embodiment 1, and will not be repeated here.

[0089] In this embodiment, the installation process of the cantilever work platform is as follows:

[0090] Step 1: Prepare accessories

[0091] According to the force requirements and working conditions, the models of the components of the cantilever work platform are selected and processed to obtain the first support beam 2, the platform plate 3 and the guardrail 4;

[0092] Step 2: Pre-embedded anchor 11

[0093] According to the calculation results, the number and spacing of the anchors 11 required for installing the cantilever work platform are obtained, and the anchors 11 are pre-buried in the structural layer 1 in advance. Alternatively, the existing anchors 11 are used. It should be noted that in this embodiment, in addition to the need to arrange the anchors 11 at the positions where the fixed sections 21 of the two first support beams 2 are located, the parts of the structural layer 1 close to the platform plate 3 also need to be provided with anchors 11 to achieve a detachable connection between the first connecting member 324 and the structural layer 1.

[0094] Step 3: Assemble the first support beam 2 and the platform plate 3

[0095] like Figure 5 As shown, the two first support beams 2 are carried to the location to be installed. At this time, the fixed sections 21 and the cantilever sections 22 of the two first support beams 2 are placed in the structural layer 1, and the first support beams 2 are slidably clamped between the anchor 11 and the third connecting member 5. The second clamping portions 3231 at both ends of the third support beam 323 are clamped in the two limiting grooves 221 of the two first support beams 2, and the first connecting member 324 is connected to the anchor 11 to achieve a detachable connection between the platform plate 3 and the first support beam 2. At this time, the pedal portion 31 is in a folded state.

[0096] like Figure 6As shown, the two first support beams 2 are pushed so that the cantilevered section 22 of the first support beam 2 is located outside the structural layer 1. At this time, the pedal part 31 is unfolded under the joint action of the first connecting member 324, the third support beam 323 and the pulley 3121, and the pedal part 31 is in an unfolded state.

[0097] Then, the two first support beams 2 are locked and fixed on the anchoring member 11 through the third connecting member 5 .

[0098] Step 5: Install guardrail 4

[0099] The guardrail 4 is moved to the corresponding position, the columns 41 are correspondingly inserted into the limiting columns 222 , and are fastened and fixed by bolts to complete the detachable connection between the guardrail 4 and the two first support beams 2 .

[0100] After the cantilever work platform is used, it can be dismantled in the order of guardrail 4-platform board 3-first support beam 2, which will not be repeated here.

[0101] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
