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

[0026] As attached Figures 1 to 12 As shown, a foldable construction platform includes a bottom frame 1, side frames 2, columns 3, top rods 4, stairs 5 and platform boards 6. Side frames 2 are installed on the upper surfaces of both ends of the bottom frame 1, top rods 4 are provided on the top corners of the two side frames 2, and the platform boards 6 are fixed between the top rods 4 parallel to each other, the tail end of the stairs 5 is installed on the upper surface of the bottom frame 1, and the head end of the stairs 5 is mounted on the surface of the platform board 6, columns 3 are installed between the top rods 4 and the bottom frame 1, and a bottom plate 11 is welded on the upper surface of the bottom frame 1. The setting of the bottom plate 11 makes the bottom surface of the construction platform more stable and convenient for workers to walk.

[0027] As attached Figure 1As shown, the side frame 2 is rotatably connected to the bottom frame 1, and the height of the rotation points of the two side frames 2 should differ by the thickness of the side frame 2, so as to form a space for the side frame 2 to be folded back, and ensure that the two side frames 2 can overlap each other after turning down, so as to avoid the collision of the two side frames 2 and cause the folded side frame 2 to tilt up. The top corner of the side frame 2 is hinged to the head end of the top rod 4, and when the top rods 4 are in a horizontal state, the ends of the two symmetrical top rods 4 are just connected, and the ends of the top rods 4 are detachably connected to the top of the column 3, the bottom end of the column 3 is hinged to the bottom frame 1, and the bottom frame 1 is hinged to the tail end of the staircase 5. When the construction platform is not needed, first turn the stair 5 downward, fold it and place it on the bottom frame 1, remove the end of the top rod 4 from the column 3, make the head end of the top rod 4 turn downward 90 degrees around the top corner of the side frame 2, then turn the column 3 downward 90 degrees, fold it and place it on the bottom frame 1, and then make the top rod 4 and the side frame 2 on one side turn downward 90 degrees together, fold it and place it on the bottom frame 1, and finally make the top rod 4 and the side frame 2 on the other side turn downward 90 degrees together and place it on the upper surface of the folded side frame 2. The overall folding and storage of the construction platform can be achieved with simple operations, reducing the space occupied by the construction platform and improving the convenience of moving the construction platform. The setting of the stairs can facilitate the workers to climb onto the construction platform without vertical climbing, reducing the risk of accidents for the workers, ensuring the safety of the workers, and making it easier for the workers to carry some work equipment or items after freeing their hands.

[0028] As attached Figures 2 to 4As shown, the staircase 5 includes an upper staircase 51, a lower staircase 52, a bracket 53 and an anti-skid plate 54. The bottom end of the lower staircase 52 and the bottom frame 1, the top end of the lower staircase 52 and the bottom end of the upper staircase 51, and the top end of the bracket 53 and the top end of the lower staircase 52 are all hinged. The bottom end of the bracket 53 abuts against the anti-skid plate 54, and the anti-skid plate 54 is fixed to the upper surface of the bottom frame 1. When the bottom end of the bracket 53 abuts against the anti-skid plate 54 and the top of the upper staircase 51 is placed on the surface of the platform plate 6, the upper staircase 51 and the lower staircase 52 are on the same inclined straight line. The setting of the bracket 53 improves the bearing capacity of the upper staircase 51 and the lower staircase 52, reduces the risk of loosening or breaking of the upper staircase 51 and the lower staircase 52 during use, and ensures the safety of the staff. The lower staircase 52 includes a pedal 521, a connecting rod 522, a chain 523 and a mounting plate 524. The mounting plate 524 is provided with a plurality of pedals 521 at equal intervals. One side of the pedal 521 is hinged to the mounting plate 524, and the other side of the pedal 521 is hinged to the connecting rod 522. A chain 523 is installed between the top of the connecting rod 522 and the top of the mounting plate 524. When the chain 523 is in a vertical state, the pedal 521 is in a horizontal state, and the staff can quickly find the force point of the sole of the foot, so that the staff can walk more steadily and reduce the risk of the staff slipping and causing accidents. The structure of the upper staircase 51 is consistent with that of the lower staircase 52. The setting of the rotatable structure of the upper staircase 51 and the lower staircase 52 can reduce the length of the staircase 5 after folding, ensure that the staircase 5 can be completely stored above the bottom frame 1 after folding, avoid the staircase 5 being too long and needing to be disassembled and placed when folding, thereby reducing the workload of folding and unfolding the staircase 5.

[0029] As attached Figure 3 As shown, four limit plates 55 are welded to the upper surface of the platform plate 6, and frame plates 56 are fixed to the tops of the mounting plates 524 on both sides of the upper staircase 51. When the top of the upper staircase 51 is placed on the platform plate 6, the frame plates 56 cover the upper surface of the platform plate 6, and the frame plates 56 are just embedded between the two limit plates 55. The limit plates 55 are used to limit the frame plates 56 to prevent the frame plates 56 from moving on the platform plate 6, thereby preventing the upper staircase 51 from shaking left and right on the platform plate 6.

[0030] As attached Figure 5As shown, sleeves 61 adapted to the frame of the side frame 2 are welded symmetrically on the four corners of the bottom frame 1. The sleeve 61 is U-shaped when viewed from above. When the side frame 2 is turned up 90 degrees and the side frame 2 and the bottom frame 1 are perpendicular to each other, the frame of the side frame 2 just passes through the opening 62 and is embedded in the sleeve 61. The width of the sleeve 61 is greater than the width of the frame of the side frame 2. A hinged limit hook 72 that can be rotated up and down is provided on one side surface of the sleeve 61 near the opening 62. The end of the sleeve 61 near the opening 62 is A slot 71 corresponding to the limiting hook 72 is provided on the other side surface. When the side frame 2 is flipped upward by 90 degrees and the frame of the side frame 2 is embedded in the sleeve 61, the limiting hook 72 is flipped downward and just embedded in the slot 71, and the outer surface of the limiting hook 72 covers the frame surface of the side frame 2. The side frame 2 is fixed in the sleeve 61 by the limiting hook 72, which improves the stability of the connection between the side frame 2 and the bottom frame 1, keeps the side frame 2 and the bottom frame 1 in a perpendicular state to each other, and reduces the risk of rotation of the side frame 2 during use.

[0031] As attached Figures 6 to 7 As shown, the column 3 includes an upper upright rod 31 and a lower upright rod 32, the upper upright rod 31 and the lower upright rod 32 are hinged, the top of the upper upright rod 31 is detachably connected to the top rod 4, the bottom of the lower upright rod 32 is hinged to the bottom frame 1, the sleeve 61 is fixed to the outer side of the top of the lower upright rod 32, and the sleeve 61 is also provided with a slot 71 and a limit hook 72. When the upper upright rod 31 is flipped upward and the upper upright rod 31 and the lower upright rod 32 are on the same straight line, the upper upright rod 31 is embedded in the sleeve 61, and then the limit hook 72 is flipped downward to just embed into the slot 71, and the appearance of the limit hook 72 The upper and lower uprights 31 are fixed in the sleeve 61 by the limit hook 72, thereby improving the stability of the connection between the upper and lower uprights 31 and 32, so that the upper and lower uprights 31 and 32 are kept in the same straight line, and the upper and lower uprights 31 are prevented from rotating during use. In addition, the rotatable structure of the upper and lower uprights 31 and 32 can reduce the length of the column 3 after folding, and ensure that the column 3 can be completely stored above the bottom frame 1 after folding, so as to avoid the need to disassemble and place the column 3 when folding due to its excessive length, thereby reducing the workload of folding and unfolding the column 3.

[0032] As attached Figures 6 to 7 As shown, the upper upright rod 31 is a hollow structure, and a clamping block 8 is fixed to the end surface of the top rod 4 close to the side of the column 3. When the upper upright rod 31 and the lower upright rod 32 are in a vertical state and the top rod 4 is in a horizontal state, the clamping block 8 of the top rod 4 is just embedded in the hollow of the upper upright rod 31. The upper upright rod 31 and the lower upright rod 32 support the top rod 4, thereby increasing the bearing capacity of the top rod 4 and reducing the risk of the top rod 4 breaking during use.

[0033] As attached Figure 8 and Fig.12As shown, a baffle 9 is provided inside the side frame 2, and the baffle 9 is detachably connected to the side frame 2, and baffles 9 are also provided between the two side frames 2 and the columns 3, one side of the baffle 9 is rotatably connected to the side frame 2, and the other side of the baffle 9 covers the surface of the column 3. The setting of the baffle 9 can isolate and protect the staff and the stairs 5. At the same time, the baffle 9 located between the side frame 2 and the column 3 can be rotated around the side close to the side frame 2 to play the role of a door, so that the staff can enter and exit easily.

[0034] As attached Figure 8 and Fig.12 As shown, positioning pins 91 are fixed on both sides of the baffle plate 9 inside the side frame 2, and the positioning pins 91 are in an inverted L shape. Positioning sleeves 92 that are compatible with the positioning pins 91 are fixed on the surface of the side frame 2, and the positioning pins 91 can be slid up and down and embedded in the positioning sleeves 92. The baffle plate 9 provided between the side frame 2 and the column 3 has only one side close to the side frame 2 fixed with the positioning pin 91, and a positioning sleeve 92 that is compatible with the positioning pin 91 is fixed on the surface of the side frame 2. The positioning pin 91 of the baffle plate 9 can be movably embedded in the positioning sleeve 92 of the side frame 2. When installing the baffle plate 9, the positioning pin 91 can be embedded in the positioning sleeve 92 from top to bottom for positioning to facilitate quick installation.

[0035] When the construction platform is needed, first make the side frame 2 on one side drive the top rod 4 to flip upward 90 degrees, so that the side frame 2 and the bottom frame 1 are perpendicular to each other. At the same time, after the frame of the side frame 2 is embedded in the sleeve 61, the limiting hook 72 on the sleeve 61 is flipped downward and embedded in the card slot 71, and the outer surface of the limiting hook 72 covers the frame surface of the side frame 2. The side frame 2 is fixed in the sleeve 61 by the limiting hook 72, which improves the stability of the connection between the side frame 2 and the bottom frame 1, keeps the side frame 2 and the bottom frame 1 perpendicular to each other, and reduces the risk of the side frame 2 rotating during use. Then repeat the above steps to fix the other side frame 2 The side frames 2 on the sides are fixed vertically, and then the lower upright rod 32 and the upper upright rod 31 on the bottom frame 1 are respectively rotated upward by 90 degrees. When the upper upright rod 31 and the lower upright rod 32 are in the same straight line and the upper upright rod 31 is embedded in the sleeve 61, the limiting hook 72 on the lower upright rod 32 is turned downward and embedded in the card slot 71, and the upper upright rod 31 is fixed in the sleeve 61 by the limiting hook 72 to improve the stability of the connection between the upper upright rod 31 and the lower upright rod 32, so that the upper upright rod 31 and the lower upright rod 32 are kept in the same straight line to prevent the upper upright rod 31 from rotating during use, and then the top rods 4 on the two side frames 2 are turned upward. The upper staircase 51 is then turned upward to embed the block 8 of the top rod 4 into the hollow of the corresponding upper upright rod 31, so that the top rod 4 and the upper upright rod 31 are perpendicular to each other, and then the lower staircase 52 is rotated upward, and the bracket 53 is unfolded to press against the anti-slip plate 54 to fix the inclination angle of the lower staircase 52, and then the upper staircase 51 is turned upward to make the frame plate 56 of the upper staircase 51 rest on the platform plate 6, and the frame plate 56 is just embedded between the two limit plates 55 to achieve the fixation of the upper staircase 51, and finally the pedal 521 and the connecting rod 522 are pulled downward to make the chain 523 straighten in a vertical state and the pedal 521 in a horizontal state, and the upper staircase 51 is turned upward to make the upper staircase 51 be supported on the platform plate 6, and the frame plate 56 is just embedded between the two limit plates 55 to achieve the fixation of the upper staircase 51. The unfolding operation of the construction platform is completed. When the construction platform is not needed, the folding and storage of the construction platform can be realized by performing the reverse operation according to the above steps, thereby reducing the space occupied by the construction platform and improving the convenience of moving the construction platform. At the same time, the setting of the overall foldable structure of the construction platform can speed up the construction of the construction platform, thereby improving the construction efficiency. The setting of the stairs can facilitate the staff to board the construction platform without vertical climbing, reduce the risk of accidents for the staff, ensure the safety of the staff, and make it easier for the staff to carry some work equipment or items after freeing their hands. When it is necessary to build a construction platform horizontally, the ear plates 12 welded on the side frames 2 of two adjacent construction platforms are docked, and screws or pins are passed through the corresponding ear plates 12 on the two adjacent construction platforms for fixed connection. The operation is simple and convenient, which improves the connection stability between the horizontally built construction platforms, ensures the safety of the staff, and speeds up the horizontal construction of the construction platform, thereby improving the construction efficiency.

[0038] In the second step, the limiting hook 72 on the sleeve 61 is turned downward and inserted into the slot 71, and the side frame 2 is fixed in the sleeve 61 by the limiting hook 72, so as to improve the stability of the connection between the side frame 2 and the bottom frame 1, so that the side frame 2 and the bottom frame 1 are kept perpendicular to each other, and the risk of the side frame 2 rotating during use is reduced;

[0039] Step 3: Repeat steps 1 and 2 to vertically fix the side frame 2 on the other side;

[0040] Step 4: Rotate the lower upright 32 and the upper upright 31 on the bottom frame 1 upwards by 90 degrees respectively, so that the upper upright 31 and the lower upright 32 are on the same straight line and the upper upright 31 is embedded in the sleeve 61;

[0043] Step 7: Rotate the lower staircase 52 upward, unfold the bracket 53 to press against the anti-slip plate 54 to fix the inclination angle of the lower staircase 52, and at the same time increase the bearing capacity of the upper staircase 51 and the lower staircase 52, reduce the risk of the upper staircase 51 and the lower staircase 52 becoming loose or broken during use, and ensure the safety of the staff;

[0044] In the eighth step, the upper staircase 51 is turned upward again, so that the frame plate 56 of the upper staircase 51 is placed on the platform plate 6, and the frame plate 56 is just embedded between the two limit plates 55. The limit plates 55 are used to limit the frame plate 56 to prevent the frame plate 56 from moving on the platform plate 6, thereby preventing the upper staircase 51 from shaking left and right on the platform plate 6, and achieving the fixing of the upper staircase 51;
