DETAILED DESCRIPTION

[0042] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model; obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments; based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

In addition, the term "first", "second" is only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0044] In the description of the utility model, it needs to explain, unless otherwise explicitly provided and limited, the term "installation", "set with", "sleeve set / interface", "connection" and so on, should be broad understanding, for example "connection", can be wall-mounted connection, can also be detachable connection, or integrally connected, can be mechanical connection, can also be electrical connection, can be directly connected, can also be indirectly connected through intermediate medium, can be the internal communication of two elements, for ordinary skilled in the art, the specific meaning of the above-mentioned terms in the utility model can be understood according to the specific circumstances.

[0045] As Figures 1-7 The utility model discloses a folding bent cap construction platform, the construction platform sets up on the distribution beam that extends from the bent cap both sides, supplies the construction personnel to pass through and stand. The construction platform includes platform subassembly 1, guardrail subassembly 2 and first connecting subassembly 3. Overall, the platform subassembly 1 with the bottom of guardrail subassembly 2 is rotatably connected through first connecting subassembly 3, to realize the folding and unfolding between platform subassembly 1 and guardrail subassembly 2. Further, guardrail subassembly 2 includes first guardrail 21, second guardrail 22 and second connecting subassembly 23, first guardrail 21 with second guardrail 22 is movably connected through second connecting subassembly 23, to realize the collection and extension of guardrail subassembly 2 in the height direction. First connecting subassembly 3, second connecting subassembly 23 also have the limiting effect, so that platform subassembly 1, first guardrail 21 and second guardrail 22 can keep stable unfolded form.

[0046] As Figures 3-4As shown, the platform component 1 includes a platform frame 11, a walking platform 12, and a kick plate 13. Generally, the walking platform 12 is positioned on top of the platform frame 11, and the kick plate 13 is vertically positioned along one edge of the walking platform 12. At least four first square steel pipes 111 are welded together to form a rectangular platform frame 11, providing support for the walking platform 12 and ensuring the construction platform is stably supported on the distribution beams on both sides of the cap beam. The walking platform 12 includes a fixed plate 121, a movable plate 122, and a third connecting member. In this embodiment, the third connecting member is a second hinge 123. The fixed plate 121 is welded to the top of the platform frame 11, forming a normally open walking surface. Within the area defined by the platform frame 11, one side of the movable plate 122 is rotatably connected to the first side 1211 of the fixed plate 121 via the second hinge 123, while the other sides are free. At least two second hinges 123 are spaced apart along the extension direction of the first side 1211. In this way, the movable plate 122 can rotate around the first side 1211. Figure 3 As shown, when the movable plate 122 is in its initial position, it is in a closed state, serving as a traveling surface together with the fixed plate 121. Figure 4 As shown, when the movable plate 122 rotates to the open / closed position, the traveling plate 12 creates a passable operating space at the corresponding position, facilitating the demolding, installation, and positioning of the cap beam formwork below the traveling plate 12 by construction personnel. Preferably, to make the traveling plate 12 more stable in bearing load, a first square steel pipe 111 is welded to the fixed plate 121 below it, close to the first side 1211, to transfer the central load of the traveling plate 12.

[0047] The second hinge 123 includes a second pin 1231. In existing construction platforms, the second pin 1231 protrudes from the surface of the walking plate 12, making it easy for construction workers to kick the second pin 1231 while walking, potentially causing a safety accident. To solve this problem, such as... Figure 5 As shown, in this technical solution, the second pin 1231 is set at the bottom of the walking plate 12. This optimization ensures the flatness of the walking surface and greatly avoids the above-mentioned construction risks.

[0048] For ease of description, the side of the fixing plate 121 that is opposite to the first side 1211 is defined as the second side 1212. Figures 3-4As shown, a section of second square steel pipe 15 is vertically welded to each of the two corners of the platform frame 11, and the two sections of second square steel pipe 15 are located at both ends of the second side 1212. The kick plate 13 is disposed between the two sections of second square steel pipe 15, and is welded to the second square steel pipe 15 on both sides. It can be understood that, as a supporting structure for the kick plate 13, the two sections of second square steel pipe 15 are part of the platform assembly 1.

[0049] like Figure 6 As shown, the first guardrail 21 has a rectangular guardrail frame formed by welding four square steel pipes around its outer perimeter. A protective net 213 is installed between the guardrail frames to form a protective barrier for construction personnel. For ease of description, the square steel pipes located on both sides of the first guardrail 21 are referred to as third steel pipes 211.

[0050] The connection method between the guardrail component 2 and the platform component 1 will now be described. For example... Figure 6 As shown, the first connecting assembly 3 is provided at the position where the second square steel pipe 15 and the third square steel pipe 211 are axially connected. The first connecting assembly 3 includes a rotating component and a limiting assembly 32. In this embodiment, the rotating component is a first hinge 31. The first hinge 31 includes a first pin 311 and a connecting plate 312. The limiting assembly 32 adopts a latch-type structure, including a limiting female component 321 and a movable latch 322. The limiting female component 321 is vertically fixed to the surface of the second square steel pipe 15 near its end, and its extension direction is parallel to the length direction of the second square steel pipe 15. The first pin 311 is vertically fixed to the thickness direction of the limiting female component 321 and extends outward from both sides of the limiting female component 321. One end of the connecting plate 312 is rotatably connected to the first pin 311, and the other end is fixed to the surface of the third square steel pipe 211 near its end. Necessary: ​​The connecting plate 312 is provided with a clearance groove, which at least covers the vertical projection range of the limiting female member 321 on the connecting plate 312, so that the connecting plate 312 does not jam with the limiting female member 321 when rotating around the first pin 311; at the same time, the connecting plate 312 is not connected to the second square steel pipe 15. In this way, the connecting plate 312 can drive the third-party steel pipe 211 to rotate around the first pin 311. Since the first connecting components 3 are provided between the third-party steel pipe 211 and the second square steel pipe 15 on both sides, the guardrail assembly 2 rotates around the line connecting the two first connecting components 3 to realize the folding and unfolding of the platform assembly 1 and the guardrail assembly 2.

[0051] like Figure 2As shown, when the guardrail assembly 2 is in the initial position, the guardrail assembly 2 is in a relatively close form with the platform assembly 1, so as to facilitate storage and transportation after construction is completed. Figure 1 As shown, when the guardrail assembly 2 is rotated to the first position, the guardrail assembly 2 is perpendicular to the platform assembly 1, and the construction platform enters the working form. It can be understood that the perpendicular relationship is not an absolute right angle relationship in the mathematical sense, and when the included angle between the guardrail assembly 2 and the platform assembly 1 is set to 80° to 90°, it can be considered that the normal use of the construction platform does not cause any impact. When the guardrail assembly 2 is in the first position, the third-party steel pipe 211 and the second-party steel pipe 15 abut on the side away from the first hinge 31, so that the guardrail assembly 2 cannot continue to rotate away from the platform assembly 1. However, in the direction close to the platform assembly 1, the guardrail assembly 2 still has a rotating freedom degree, and if there is no fixing measure, the guardrail assembly 2 is easy to be affected by external force and fall towards the platform assembly 1, thereby causing overturning.

[0052] To solve this problem, as shown in the accompanying drawings, Figure 6 As shown, a limiting opening 3211 extending through the plate body is arranged on the limiting female part 321, the limiting opening 3211 extends along the length direction of the second-party steel pipe 15, and the opening faces upward. The movable latch 322 is movably connected to the surface of the skirting board 13, and enters the limiting opening 3211 through reciprocating movement to fit on the surface of the connecting plate 312. Due to the limiting effect of the limiting opening 3211, the movable latch 322 does not have a movement freedom degree in the rotating direction of the connecting plate 312, thereby preventing the connecting plate 312 from rotating in the direction close to the platform assembly 1, and macroscopically limiting the guardrail assembly 2 from falling towards the platform assembly 1. In this embodiment, the movable latch 322 is rotatably connected to the surface of the skirting board 13, and enters or exits the limiting opening 3211 from the end of the limiting female part 321 through rotation of the movable latch 322. In other embodiments, the movable latch 322 can be slidably connected to the skirting board 13 along a direction perpendicular to the limiting female part 321, and enters or exits the limiting opening 3211 from the side of the limiting female part 321 in a straight line.

[0053] In other embodiments, the limiting female part 321 can also be fixedly connected to the surface of the skirting board 13, and the movable latch 322 is movably connected to the surface of the guardrail assembly 2. When the guardrail assembly 2 is in the first position, the movable latch 322 is slid or rotated into the limiting opening 3211 and straddles the surface of the skirting board 13 and the bottom of the guardrail assembly 2, thereby limiting the rotation of the guardrail assembly 2 towards the platform assembly 1. When the movable latch 322 is removed from the limiting opening 3211, the guardrail assembly 2 can be rotated towards the platform assembly 1 to achieve folding. It should be understood that the positions of the limiting female part 321 and the movable latch 322 are flexible and variable, as long as the movable latch 322 can enter the limiting opening 3211 and straddle the surface of the skirting board 13 and the bottom of the guardrail assembly 322 to achieve limiting.

[0054] As an equivalent technical alternative, in other embodiments, the platform assembly 1 and the guardrail assembly 2 can also use a movable triangular support to fold, unfold and fix.

[0055] In this embodiment, the passing width of the platform assembly 1, i.e. the dimension perpendicular to the direction of the skirting board 13, is 850 mm. In order to minimize the overall size of the construction platform after folding, the height of the first guardrail 21 is not greater than 850 mm. Obviously, this height does not meet the relevant construction specifications for the height of the guardrail. To solve this problem, a second guardrail 22 is movably connected to the top of the first guardrail 21 to supplement the height of the guardrail assembly 2.

[0056] As shown in Figure 7 In this embodiment, the first guardrail 21 and the second guardrail 22 are connected in an extendable manner. The second guardrail 22 is a "door" shaped structure formed by welding at least three square steel pipes. For the convenience of the following description, the square steel pipe horizontally placed on the top of the first guardrail 21 is referred to as the fourth square steel pipe 212, and the square steel pipes located on both sides of the second guardrail 22 are referred to as the fifth square steel pipes 221. The fifth square steel pipes 221 are sleeved on the third square steel pipes 211 and can slide along the length direction of the third square steel pipes 211.

[0057] Now the limiting method between the fifth square steel pipes 221 and the third square steel pipes 211 will be described. As shown in Figure 7As shown, the second connecting assembly 23 is arranged at the position where the fourth square steel tube 212 is close to the fifth square steel tube 221. The second connecting assembly 23 has a similar latch structure, which includes a sliding piece 231, a limiting ring 232 and a limiting block 233. The sliding piece 231 is attached to the surface of the fourth square steel tube 212 and slides along the length direction of the fourth square steel tube 212, i.e. perpendicular to the fifth square steel tube 221. The limiting ring 232 is arranged above the sliding piece 231 and welded to the fourth square steel tube 212 at both sides, for limiting the movement of the sliding piece 231 away from the surface of the fourth square steel tube 212. The limiting block 233 is arranged at the side of the sliding piece 231 away from the fifth square steel tube 221. The distance between the limiting block 233 and the limiting ring 232 is less than the length of the sliding piece 231, so as to prevent the sliding piece 231 from falling off after sliding out of the limiting ring 232. Correspondingly, a pair of limiting holes 222 are arranged on the side wall of the fifth square steel tube 221, which are located in the sliding direction of the sliding piece 231. The cross section of the limiting hole 222 matches the sliding piece 231, so as to allow the sliding piece 231 to pass through. When the sliding piece 231 passes through the pair of limiting holes 222 under the action of external force and extends out of the outer edge of the end of the third square steel tube 211, the fifth square steel tube 221 is clamped and cannot slide down. At this time, the gravity acting on the second guardrail 22 increases the friction between the sliding piece 231 and the edge of the limiting hole 222, so as to be fixed more firmly in the limiting hole 222. At this time, the third square steel tube 211 and the fifth square steel tube 221 are in a locked state, i.e. cannot be extended or retracted. When the sliding piece 231 exits the limiting hole 222 under the action of external force, the third square steel tube 211 and the fifth square steel tube 221 are in an unlocked state, and the fifth square steel tube 221 can slide down or be lifted up, so as to adjust the overall height of the guardrail assembly 2.

[0058] The fifth square steel tube 221 is arranged with two pairs of limiting holes 222 in the height direction. For the convenience of description, the lower pair of limiting holes 222 is denoted as the first limiting hole 2221, and the upper pair of limiting holes 222 is denoted as the second limiting hole 2222. When the construction platform is in the working state, the sliding piece 231 and the first limiting hole 2221 are in the locked state, and the height of the guardrail assembly 2 is maximum. When the construction is completed, the sliding piece 231 and the second limiting hole 2222 are in the locked state, and the height of the guardrail assembly 2 is adjusted to the minimum, so as to be stored and transported.

[0059] For those skilled in the art, there are many ways to realize the height adjustment of the guardrail assembly 2. In other embodiments, the second connecting assembly 23 can adopt a self-recovery sliding lock, which is arranged on the surface of the fifth square steel tube 221 and is limitedly matched with a plurality of limiting through holes arranged on the side wall of the third square steel tube 211. Similar to a traditional umbrella, the construction personnel only need to pull the fifth square steel tube 221 while pressing the sliding lock, so as to realize the telescopic connection between the third square steel tube 211 and the fifth square steel tube 221. For example, the guardrail assembly 2 can adopt a scissor fork type structure, and the height adjustment can be realized by lifting and pressing the guardrail assembly 2. For another example, the first guardrail 21 and the second guardrail 22 can be connected in a folding manner, and specifically, the first connecting assembly 3 can be used for rotary connection and fixation.

[0060] As shown in Figures 3-4 On one side of the platform assembly 1 relative to the skirting board 13, a through-length angle iron 14 is arranged, and a plurality of first mounting holes 141 are arranged on the horizontal limb of the angle iron 14 in the length direction. Through the first mounting hole 141, the construction personnel can use a bolt assembly to fix the construction platform on the top of the distribution beam. A pair of second mounting holes 142 are arranged on the side wall of the angle iron 14, the second square steel tube 15 and the fifth square steel tube 221. Through the second mounting hole 142, the construction personnel can use a bolt assembly to splice the construction platform along the extension direction of the cover beam.

[0061] In summary, the foldable bent cap construction platform provided by the embodiment of the utility model, the platform component 1 and the guardrail component 2 are rotatably connected through the first connecting component 3, so that the platform component 1 and the guardrail component 2 can be quickly converted between two states of mutual adhesion and mutual vertical fixation, greatly simplifying the erection process before construction and the disassembly, storage and transportation work after construction is completed. As for the guardrail component 2, the first guardrail 21 and the second guardrail 22 are connected in an extendable manner, the support height of the guardrail component 2 can be quickly adjusted, sufficient protection is provided for construction personnel, and the overall size of the construction platform after being folded is minimized. During the process of unfolding and erection or folding and storage of the construction platform, the connecting components are stably connected with the construction platform body and do not fall off, avoiding the problem that the traditional assembled construction platform is easy to lose parts. As for the walking plate 12, the second pin shaft 1231 of the second hinge 123 is arranged at the bottom of the walking plate 12, which optimizes the flatness of the walking surface and avoids the construction risk caused by the second pin shaft 1231 being kicked by the construction personnel. The construction platform has simple and direct connection mode, stable component stress, and convenient and easy-to-understand locking and unlocking operation, further improving the construction efficiency.

[0062] The above merely describes the preferred specific embodiments of the utility model, and does not limit the patent range of the utility model, and any equivalent transformation using the content of the utility model specification belongs to the protection range of the utility model.
