Description

Technical Field

[0001] The present invention relates to the technical field of construction scaffolds, and particularly to a standardized, foldable, variable-height and lightweight operation scaffold for building construction. Background Art

[0002] During the construction of the main structure, it is often necessary to set up a disc buckle scaffold on site as an operation scaffold to carry out the work of binding wall and column steel bars. However, the disc buckle scaffold is a standardized product. To meet the requirements of on-site safety construction and set up a climbing ladder layout, multiple layers of scaffolds are often required. The total weight of the scaffold set up for binding a single column of steel bars exceeds 500 kg. It is heavy, wide and not easy to operate.

[0003] In addition, the disc buckle scaffold is composed of single steel pipes. During erection, it needs to be installed one by one, which is rather cumbersome, and its own weight is large, which is further not conducive to accelerating the construction speed. Summary of the Invention

[0004] To solve the above problems, the present invention discloses a standardized, foldable, variable-height and lightweight operation scaffold for building construction, including side frames arranged on both sides. A folding frame is arranged between the two side frames. A plurality of stabilizing rods are arranged inside the side frames, and a working platform is lapped on the side frames. The side frames and the folding frame can form an M-shaped folding mode, making the operation scaffold easy to set up and use.

[0005] The side frame includes two vertical rods, and a plurality of short cross rods are fixedly connected between the two vertical rods. A socket end is fixedly connected to the upper end of the vertical rod. A climbing ladder is arranged in the middle of one of the side frames. The climbing ladder is provided to facilitate construction workers to reach the working platform.

[0006] The end of the folding frame is rotatably connected to the vertical rod. The folding frame is divided into left and right sides, and the two sides are hinged to each other. The folding frame includes folding rods, and connecting rods are fixedly connected between the folding rods on the same side. The end of the folding rod is fixedly connected with a connecting piece, and one side of the connecting piece is provided with a U-shaped opening. One of the connecting pieces covers the adjacent other connecting piece, and a first bolt is inserted through the middle edge. A U-shaped elastic member is wound around the first bolt, and the end of the U-shaped elastic member is inserted through the connecting piece. When the two folding rods are not collinear, at this time the U-shaped elastic member releases elastic force to ensure that the folding rods are in a folded state. When the two folding rods are unfolded and collinear, the U-shaped elastic member is compressed to store elastic potential energy, and the force exerted by the U-shaped elastic member on the folding rods forces them to maintain the state. When the acting force and the axis of the folding rod are collinear, it is to ensure that the two folding rods are kept straight and collinear, and at this time the folding frame is in an unfolded state. This setting ensures that the operation scaffold remains in a folded state during transportation, and at the same time remains in an unfolded state after unfolding, which is easy to set up.

[0007] Preferably, the stabilizing rod includes a rod member, and a first arc-shaped member is fixedly connected to the end of the rod member. The middle of the first arc-shaped member is provided with an opening, and a second arc-shaped member is arranged in the opening. A second bolt is inserted through the ends of the first arc-shaped member and the second arc-shaped member. Both the first arc-shaped member and the second arc-shaped member are clamped on the short cross bar, and the convex surface preset at the end of the second arc-shaped member abuts against the side wall of the short cross bar. The stabilizing rod is used to support inside the side frame to improve the stability of the operating frame, and the structure at its end can be quickly clamped on the short cross bar to improve the installation speed.

[0008] Preferably, a base is assembled at the lower end of the vertical rod. The base includes a bottom plate, and a vertical rod is fixedly connected to the middle of the upper end of the bottom plate. A support ring is threadedly connected to the vertical rod. The support ring can adjust its position on the vertical rod, thereby realizing the support height of the base, which is suitable for the construction of the operating frame in the case of uneven ground at the construction site.

[0009] Preferably, an external support is assembled on the vertical rod. The external support includes a long rod and a short rod, and one end of the short rod is hinged to the side wall of the end of the long rod. One end of each of the long rod and the short rod is fixedly connected with a tightening hoop, and the tightening hoop cooperates with the vertical rod. The other end of the long rod is fixedly connected with an anti-slip head. The external support is used to improve the stability of the operating frame, especially for an overly high operating frame.

[0010] Preferably, the operation platform includes a fixed frame. One side of the upper end of the fixed frame is fixedly connected with a fixed plate, and the other side of the fixed frame is rotatably connected with a rotating plate. Here, both the fixed plate and the rotating plate are standing areas for operation. When construction workers reach the standing area, they should climb up from the ladder, then flip the rotating plate, and enter from below the operation platform and land on the fixed plate. This way of entering the operation platform is highly safe.

[0011] Preferably, hooks are fixedly connected to both sides of the fixed frame, and the hooks cooperate with the short cross bar. This assembly method facilitates the disassembly and assembly of the operation platform, and can conveniently transfer and install the operation platform when the height of the operating frame increases.

[0012] Preferably, the operating frame is made of aluminum alloy. Aluminum alloy has the advantage of light weight, which is beneficial for the transportation and construction by construction workers.

[0013] The beneficial effects of the present invention are as follows:

[0014] 1. In the construction of steel bar binding, the present invention is provided with a folding unit, which can quickly realize the construction of the operating frame after being unfolded and cooperating with other components, facilitating the acceleration of the construction progress. At the same time, the use of the folding unit is also beneficial for transportation.

[0015] 2. The folding structure on the folding frame includes a connecting piece, a first bolt, and a U-shaped elastic piece. Due to the use of the U-shaped elastic piece, it can ensure that the folding remains in a fully unfolded state and can also maintain the folded state when not unfolded. At the same time, this structure is simple and can reduce the weight.

[0016] 3. The present invention uses aluminum alloy material. Compared with the existing disc buckle scaffolds made of ordinary carbon steel, its weight is greatly reduced, which is beneficial for transportation and erection. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The present invention will be further illustrated below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and not to limit the scope of the present invention. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the accompanying drawings, and the terms "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component.

[0030] As Figures 1 to 9 shown, a standardized foldable variable-height light operating frame for building construction includes side frames 2 arranged on both sides. A folding frame 4 is arranged between the two side frames 2. The side frames 2 and the folding frame 4 form a foldable unit, and the folding unit is folded in an M shape. When the operating frame needs to be erected, it is the mutual stacking of the folding units. Figure 1 The figure shows the state of two folding units stacked. A number of stabilizing rods 5 are arranged inside the side frames 2 to improve the stability of the operating frame. At the same time, the stabilizing rods 5 are arranged in two ways: obliquely and horizontally, and their placement positions only need to keep the operating frame stable. A working platform 6 is lapped on the side frames 2 for the standing area of construction workers.

[0031] The side frame 2 includes two vertical rods 21. A number of short cross rods 23 are fixedly connected between the two vertical rods 21. Here, four short cross rods 23 are provided, and the distance between the upper and lower ones is 600 mm. That is, the side frame 2 is similar to a ladder in appearance. The upper end of the vertical rod 21 is fixedly connected with a socket end 24. Similarly, the lower end of the vertical rod 21 is not sealed and cooperates with the socket end 24 to ensure that the folding units can be stacked. The socket end 24 is conical for convenient insertion. A ladder 22 is arranged in the middle of one of the side frames 2 to facilitate construction workers to climb onto the working platform 6.

[0032] The end of the folding frame 4 is rotatably connected to the vertical pole 21, that is, the other side of the hinged structure at the end of the folding frame 4 is welded to the vertical pole 21, ensuring that the folding frame 4 and the side frame 2 are an integrated structure. The folding frame 4 is divided into left and right sides, and the two sides are hinged to each other, that is, the folding frame 4 itself can be folded, that is, the folding frame 4 and the side frame 2 have a three-folding mechanism and realize M-shaped folding. The folding frame 4 includes a folding rod 41, and the folding rods 41 on the same side are fixedly connected with a connecting rod 42, that is, one side of the frame 4 is I-shaped, and the end of the folding rod 41 is fixedly connected with a connecting piece 43, and one side of the connecting piece 43 is set as a U-shaped opening, one of the connecting pieces 43 covers another adjacent connecting piece 43, and the middle edge is interspersed A first bolt 44 is provided, that is, the two connecting members 43 rotate around the first bolt 44, a U-shaped elastic member 45 is wound around the first bolt 44, and the end of the U-shaped elastic member 45 is inserted into the connecting member 43. The purpose of the U-shaped elastic member 45 is that when the two folding rods 41 are collinear, the U-shaped elastic member 45 is compressed, and the direction of the force acting on the folding rod 41 is the same as the length direction of the folding rod 41. At this time, the two folding rods 41 can be kept collinear, which is beneficial to the stacking and assembly of the folding unit after the two folding rods 41 are unfolded. When the two folding rods 41 are not collinear, the force generated by the U-shaped elastic member 45 is not the same as the length direction of the folding rod 41, that is, the released elastic potential energy of the compressed U-shaped elastic member 45 drives the two folding rods 41 to fold and maintain, which is beneficial to the transportation of the folding unit.

[0033] The stabilizing rod 5 comprises a rod member 51, the end of which is fixedly connected with a first arc-shaped member 52, and the structures at both ends of the rod member 51 are the same, the middle of the first arc-shaped member 52 is opened, and a second arc-shaped member 54 is arranged in the opening, and the first arc-shaped member 52 and the second arc-shaped member 54 are both semicircular, and the ends of the first arc-shaped member 52 and the second arc-shaped member 54 are interspersed with a second bolt 53, the first arc-shaped member 52 and the second arc-shaped member 54 are both embraced on the short cross bar 23, and the preset convex surface at the end of the second arc-shaped member 54 abuts against the side wall of the short cross bar 23, when the first arc-shaped member 52 and the second arc-shaped member 54 are both embraced on the short cross bar 23, the convex surface thereof can prevent the stabilizing rod 5 from falling off, and the embracing angle is greater than 180°.

[0034] A base 3 is assembled at the lower end of the vertical pole 21 for supporting and fixing the folding unit above. The base 3 includes a bottom plate 31. The bottom plate 31 is a square plate, and four corners are provided with through holes for fixing and limiting. A vertical rod 32 is fixedly connected to the middle of the upper end of the bottom plate 31. The vertical rod 32 is fitted on the lower end of the vertical pole 21. A support ring 33 is threadedly connected to the vertical rod 32, that is, the lower end of the vertical pole 21 is in contact with the support ring 33. The height of the support ring 33 can be adjusted as needed, that is, to ensure that the support rings 33 that jointly support the same folding unit are located in the same horizontal plane.

[0035] An outer support 1 is assembled and provided on the vertical rod 21. To enhance the stability of the operation frame, especially for the support of an overly high operation frame, the outer support 1 includes a long rod 12 and a short rod 13. One end of the short rod 13 is hinged to the side wall of the end of the long rod 12. Fixing hoops 14 are fixedly connected to one end of each of the long rod 12 and the short rod 13. The fixing hoops 14 cooperate with the vertical rod 21. That is, through the fixing hoops 14, the short rod 13 is fixed to the lower part of the vertical rod 21, and the long rod 12 is fixed to the upper part of the vertical rod 12. The other end of the long rod 12 is fixedly connected with an anti-slip head 11, which has an anti-slip effect and improves the stability of the support.

[0036] The operation platform 6 includes a fixed frame 62. The fixed frame 62 has a rectangular structure. One side of the upper end of the fixed frame 62 is fixedly connected with a fixed plate 64. The other side of the fixed frame 62 is rotatably connected with a rotating plate 63. First, climb through the ladder 22, and then flip the rotating plate 63. Climb onto the fixed plate 64 from below the operation platform 6. At this time, flip the rotating plate 63 again. That is, the fixed plate 64 and the rotating plate 63 are the standing areas for the operation.

[0037] Hooks 61 are fixedly connected to both sides of the fixed frame 62. The hooks 61 cooperate with the short crossbars 23. The hooks 61 have a common structure, which is conducive to installing the operation platform 6 on the folding unit and is conducive to continuously increasing the height of the operation frame and changing the operation platform.

[0038] This operation frame uses aluminum alloy material. Using aluminum alloy material can reduce the weight of the operation frame, which is conducive to transportation, especially when it is manually erected. When single-column steel bars are tied and erected, the total mass of the erected operation frame is within 100 kg.
