Description

[0002] Scaffolding is a commonly used auxiliary equipment in construction. Scaffolding is usually composed of columns, connecting mechanisms, and frame plates. The existing connecting mechanisms include the following: a traditional buckle-type structure that uses connecting rods to connect and fix the columns; a disc-type structure that uses discs on the columns and connects the connecting rods with fixing pins; and a portal scaffold that uses connecting rods to connect portal frames, allowing for quick scaffolding construction.

[0024] The specific embodiments of the present invention are further described in detail below with reference to the accompanying drawings.

[0025] Depend on Figures 1 to 10 It can be seen that in the first embodiment (the scaffold is a single vertical structure): A scaffold for building construction comprises a door frame 1, a connecting rod 2 and a first connecting mechanism 3. The door frame 1 comprises two columns 4, a connecting rod 5 is provided between the two columns 4, a ladder 6 is provided between the connecting rod 5 and the columns 4 on both sides, the first connecting mechanism 3 can be sleeved on the column 4, a first fixing hole 7 is provided on the column 4, through holes 8 are provided on both sides of the first connecting mechanism 3, the end of the connecting rod 2 passes through the through hole 8, the first fixing hole 7 and the through hole 8 in sequence, a limiting rod 9 is provided at the end of the connecting rod 2 for rotation, and the limiting rod 9 can form a limit after rotation so that the connecting rod 2 cannot be disengaged from the first connecting mechanism 3, the other end of the connecting rod 2 is fixedly connected to another door frame 1 via the first connecting mechanism 3, so that the scaffold is formed, and a frame plate 10 is set above the adjacent door frames 1.

[0026] The two door frames 1 are connected by a connecting rod 2. The end of the connecting rod 2 cooperates with the first connecting mechanism 3 mounted on the column 4 to achieve a fixed connection with the column 4. It does not require the use of screws for connection like the traditional snap connection method, which can greatly reduce the time used to turn the nut and improve the construction efficiency.

[0027] The first connecting mechanism 3 includes two arc-shaped plates 11 hinged at one end, a through hole 8 is opened in the center of the arc-shaped plate 11, and the other ends of the two arc-shaped plates 11 are fixedly connected by a locking pin 12. A cross-shaped groove 13 is provided on the outer side of the arc-shaped plate 11. After the limit rod 9 is rotated, it is stuck in the groove 13 so that the connecting rod 2 cannot move in the through hole 8.

[0028] After the limit rod 9 is rotated, it coincides with the end of the connecting rod 2 and can pass through the through hole 8 and the first fixing hole 7. After passing through, the limit rod 9 is rotated to form a 90° angle with the connecting rod 2. The side of the limit rod 9 fits into the groove 13, forming a limiting effect on the connecting rod 2, so that the connecting rod 2 cannot be separated from the first connecting mechanism 3, thereby realizing the connection between the door frames 1 on both sides.

[0029] A sleeve 14 is provided at the bottom of the column 4, which can be sleeved with the top of the lower column 4. To strengthen the connection, the length of the sleeve 14 can be increased, or holes can be opened at the corresponding positions of the sleeve 14 and the top of the column 4, and fixed with pins, so as to prevent the scaffolding from loosening during construction, eliminate safety hazards, and ensure the safety and stability of the scaffolding.

[0030] A cross-shaped limit plate 15 is provided at both ends of the connecting rod 2. The limit plate 15 cooperates with the groove 13. The connecting rod 2 is connected to one side of the limit plate 15. The connecting rod 2 outside the limit plate 15 is located at the center of the limit plate 15. After the limit plate 15 cooperates with the groove 13, the connecting rod 2 can pass through the first fixing hole 7. The connecting rod 2 located in the middle of the limit plates 15 on both sides is connected to one side of the limit plate 15. In this way, when the two connecting rods 2 are used to cross-connect the door frame 1, the two connecting rods 2 can be staggered to avoid interference.

[0031] A slot 16 is provided at the end of the connecting rod 2, and the limit rod 9 is rotatably arranged in the slot 16. After the limit rod 9 is rotated, it can be coaxial with the connecting rod 2, thereby passing through the first fixing hole 7 or the through hole 8. After the limit rod 9 is rotated, it can form a limit at the end of the connecting rod 2 to prevent the connecting rod 2 from moving in the opposite direction.

[0032] A connecting ear 17 is provided on the side of the arc-shaped plate 11, and a connecting hole 18 is opened on the connecting ear 17. The locking pin 12 includes a connecting plate 19 and two pin shafts 20. The two pin shafts 20 are inserted into the connecting holes 18 of adjacent arc-shaped plates 11 to form a structure in which the arc-shaped plates 11 are hinged to each other; using a locking pin 12 to connect the two arc-shaped plates 11 can make the two arc-shaped plates 11 hinged, and after the ends of the mutually hinged arc-shaped plates 11 are connected again with the locking pin 12, the two arc-shaped plates 11 can be formed into a ring structure, that is, the first connecting mechanism 3, which is put on the column 4 and can cooperate with the connecting rod 2 to complete the fixation of the door frame 1.

[0033] The locking pin 12 is inserted into the connecting hole 18 through the pin shaft 20 to form a hinge on the arc plate 11. An opening can be set at the end of the pin shaft 20, and a binding wire can be passed through it after connection to quickly lock it so that it cannot move in the opposite direction and avoid falling off.

[0034] A plurality of straps 21 extend from both ends of the frame plate 10. The straps 21 on both sides of the frame plate 10 do not overlap. The straps 21 are in a semicircular structure with an opening facing downward, and can be buckled on top of the connecting rod 5 to provide support for the frame plate 10, thereby making the frame plate 10 into a working platform.

[0035] Example 2 (the scaffold is expanded horizontally): A scaffold for building construction, comprising a door frame 1, a connecting rod 2 and a first connecting mechanism 3, the door frame 1 comprising two columns 4, a connecting rod 5 is provided between the two columns 4, a ladder 6 is provided between the connecting rod 5 and the columns 4 on both sides, the first connecting mechanism 3 can be sleeved on the columns 4, the columns 4 are provided with a first fixing hole 7 and a second fixing hole 22, through holes 8 are provided on both sides of the first connecting mechanism 3, the end of the connecting rod 2 passes through the through hole 8, the first fixing hole 7 and the through hole 8 in sequence, a limiting rod 9 is provided at the end of the connecting rod 2 for rotation, and the limiting rod 9 can form a limit after rotation so that the connecting rod 2 cannot be disengaged from the first connecting mechanism 3, a plurality of door frames 1 are arranged horizontally, and adjacent door frames 1 are connected and fixed by the connecting rod 2, the connecting rods 2 on both sides of the door frame 1 are respectively connected to the first fixing hole 7 and the second fixing hole 22 on the door frame 1, so that the scaffold is formed, and a frame plate 10 is set up above the adjacent door frames 1; The first connecting mechanism 3 includes two arc-shaped plates 11 hinged at one end, a through hole 8 is opened in the center of the arc-shaped plate 11, and the other ends of the two arc-shaped plates 11 are fixedly connected by a locking pin 12. A cross-shaped groove 13 is provided on the outer side of the arc-shaped plate 11. After the limit rod 9 is rotated, it is stuck in the groove 13 so that the connecting rod 2 cannot move in the through hole 8.

[0036] Similar to the single scaffolding structure of Example 1, a connecting rod 2 is used again to connect the door frame 1 on the side of one of the door frames 1 for expansion. Since the first fixing hole 7 on the door frame 1 is already occupied, a second fixing hole 22 is set below the corresponding position of the first fixing hole 7 to achieve lateral expansion of the scaffolding.

[0037] Example 3 (the scaffold is extended vertically): A scaffold for building construction, comprising a door frame 1, a connecting rod 2 and a second connecting mechanism 23, the door frame 1 comprising two columns 4, a connecting rod 5 being provided between the two columns 4, a ladder 6 being provided between the connecting rod 5 and the columns 4 on both sides, a first fixing hole 7 being provided on the column 4, a plurality of door frames 1 being arranged longitudinally, adjacent door frames 1 being fixedly connected via a second connecting mechanism 23, a through hole 8 being provided on the second connecting mechanism 23, an end portion of the connecting rod 2 passing through the through hole 8, the first fixing hole 7 and the through hole 8 in sequence, a limiting rod 9 being provided at the end portion of the connecting rod 2 for rotation, the limiting rod 9 being able to form a limit after being rotated so that the connecting rod 2 cannot be disengaged from the second connecting mechanism 23, the other end of the connecting rod 2 being fixedly connected to the two door frames 1 on the other side via the second connecting mechanism 23, so that the scaffold is formed, and a frame plate 10 is set above the adjacent door frames 1; The second connecting mechanism 23 includes four arc-shaped plates 11 hinged in sequence, with a through hole 8 opened in the center of the arc-shaped plates 11. Adjacent arc-shaped plates 11 are fixedly connected by a locking pin 12. A cross-shaped groove 13 is provided on the outer side of the arc-shaped plate 11. After the limit rod 9 is rotated, it is stuck in the groove 13 so that the connecting rod 2 cannot move in the through hole 8.

[0038] When constructing a single scaffold in Example 1, the first connecting mechanism 3 is replaced by the second connecting mechanism 23. Compared with the first connecting mechanism 3, the second connecting mechanism 23 has two fixed positions and can be simultaneously mounted on two columns 4, thereby realizing the longitudinal expansion of the scaffold.

[0039] The second connecting mechanism 23 is hinged to the four arc-shaped plates 11 in sequence, so that the two fixed positions formed are connected to each other and cannot be separated from each other, so that the longitudinally extended scaffolding structure is stable and the positions are fixed with each other, ensuring stability during construction and avoiding safety accidents.

[0040] In the above embodiment, the first connecting mechanism 3 is in a normal use state, and the state of the first connecting mechanism 3 is maintained during storage. When in use, it can be sleeved on the column 4 and fixed with the locking pin 12. The second connecting mechanism 23 is a series connection of two first connecting mechanisms 3, and its proportion in use is not high. When construction is required, it can be connected on site, which will not delay the normal construction of the scaffolding, nor will it occupy too much inventory due to too much preparation in advance, wasting unnecessary resources.

[0041] Compared with the prior art, the present invention has the following beneficial effects: it adopts the structure of a portal scaffold, which is fixedly connected to the portal frame through connecting rods and connecting mechanisms, and does not require the use of screws or the like for connection, thereby reducing the time spent on rotating nuts, reducing the time for building the scaffold, greatly improving the building speed, and thus improving construction efficiency.
