The supporting state means that the upper rod body and the lower rod body are both in a vertical state and are abutted up and down to serve as a longitudinal beam; thereby being capable of forming a support for the support platform above.

By adopting the technical scheme, the invention relates to a quickly-disassembled and assembled folding scaffold, wherein a folding frame in the folding scaffold comprises a plurality of support platforms which are stacked up and down, and two adjacent support platforms are connected through a plurality of folding stand columns. The folding upright column comprises an upper rod body, a lower rod body and a corner component, wherein the upper rod body is hinged with the bottom of a supporting platform on the upper side of the upper rod body, and the lower rod body is hinged with the top of the supporting platform on the lower side of the lower rod body; and an upper connecting piece and a lower connecting piece in the corner component are respectively connected to the lower end part of the upper rod body and the upper end part of the lower rod body in a limiting and rotating manner along the circumferential direction of the rod body. When the telescopic rod is in a storage state, the hinge axes of the upper connecting piece and the lower connecting piece are parallel to the hinge axis of the upper rod body relative to the supporting platform on the upper side of the upper rod body and the hinge axis of the lower rod body relative to the supporting platform on the lower side of the lower rod body. Under the action of external force, the upper rod body is turned over to a certain angle along the hinge axes of the upper rod body and the lower rod body and is closed, and the two adjacent supporting platforms are relatively close to each other, so that the folding and the storage and the transportation are facilitated. When the scaffold needs to be unfolded to form a support, the scaffold is gradually lifted from the uppermost layer of the folding scaffold through an externally-arranged lifting mechanism (such as a crane), and the supporting platform on the uppermost layer is lifted to a certain height. In the lifting process, the support platform on the second layer is relatively far away, the upper rod body is relatively far away from the lower rod body at the moment, the turning angle of the upper rod body and the lower rod body is increased along the hinge axes of the upper rod body and the lower rod body, the upper rod body and the lower rod body are vertically abutted to form a longitudinal beam, and the longitudinal beam can be locked through a certain structure at the moment.

Meanwhile, the folding scaffold is recycled, and the transportation space is saved. More importantly, compared with a scissor-type supporting scheme, the scheme enables the corner component connecting the upper rod body and the lower rod body to rotate circumferentially on the basis of folding in a hinged mode; after the circumferential rotation is generated, as mentioned above, because the three hinge axes are not all parallel, the three hinge axes of the upper rod body and the lower rod body are limited mutually, so as to achieve a self-locking state, and thus, the self-locking mechanism is stabilized in a supporting state.

In this technical scheme, a single folding frame 1 is as an integral folding unit, realizes folding and accomodating in the direction of height. And simultaneously a plurality of folding frames 1 are needed to be spliced, thereby forming the complete scaffold for buildings.

On the basis of the above scheme, the present embodiment contemplates providing a foldable scaffold that is convenient to disassemble and assemble and has high support strength. Therefore, the scheme for further refining is as follows: the folding upright column comprises an upper rod body 12 hinged with the bottom of a supporting platform 11 on the upper side of the folding upright column, a lower rod body 13 hinged with the top of the supporting platform 11 on the lower side of the folding upright column, and a corner component for connecting the upper rod body 12 and the lower rod body 13. The corner assembly comprises an upper connector 14 and a lower connector 15 which are hinged. The upper connecting piece 14 and the lower connecting piece 15 are respectively connected to the lower end part of the upper rod body 12 and the upper end part of the lower rod body 13 in a limiting rotation mode along the circumferential direction of the rod bodies. When the hinge axis L1 of the upper and lower connecting

members

14 and 15 is parallel to the hinge axis L2 of the upper rod 12 relative to the upper supporting platform 11 and the hinge axis L3 of the lower rod 13 relative to the lower supporting platform 11, the upper rod 12 and the lower rod 13 can be turned over relatively. When the hinge axis L1 of the upper and lower connecting

members

14 and 15 is not parallel to the hinge axis L2 of the upper rod 12 relative to the upper supporting platform 11 and the hinge axis L3 of the lower rod 13 relative to the lower supporting platform 11, the upper and

lower rods

12 and 13 are locked in the supporting state. The support state referred to herein means that the upper rod 12 and the lower rod 13 are both in a vertical state and abut against each other up and down to serve as a longitudinal beam. So that it is possible to form a support for the support platform 11 above.

The embodiment relates to a quick assembly disassembly's foldable scaffold, and foldable frame 1 in this foldable scaffold includes a plurality of supporting platforms 11 of setting up stacks from top to bottom, is connected through many folding stands between two adjacent supporting platforms 11. The folding upright column comprises an upper rod body 12, a lower rod body 13 and a corner component, wherein the upper rod body 12 is hinged with the bottom of a supporting platform 11 on the upper side of the upper rod body, and the lower rod body 13 is hinged with the top of the supporting platform 11 on the lower side of the lower rod body. And an upper connecting piece 14 and a lower connecting piece 15 in the corner component are respectively connected to the lower end part of the upper rod body 12 and the upper end part of the lower rod body 13 in a limiting rotation mode along the circumferential direction of the rod body. In the storage state, the hinge axis L1 of the upper and

lower links

14, 15 is parallel to the hinge axis L2 of the upper rod 12 relative to the upper support platform 11 and the hinge axis L3 of the lower rod 13 relative to the lower support platform 11. Under the action of external force, the upper rod body 12 is turned over to a certain angle relative to the lower rod body 13 along the hinge axes of the upper rod body and the lower rod body and is closed, and the two adjacent supporting platforms 11 are relatively close to each other, so that the folding is realized, and the storage and the transportation are convenient. When the scaffold needs to be unfolded to form a support, the scaffold is gradually lifted from the uppermost layer of the folding scaffold through an externally-arranged lifting mechanism (such as a crane), and the supporting platform 11 on the uppermost layer is lifted to a certain height. In the lifting process, the supporting platform 11 on the second layer is relatively far away, the turning angle of the upper rod body 12 relative to the lower rod body 13 is increased along the hinge axis between the upper rod body and the lower rod body, until the upper rod body 12 and the lower rod body 13 are vertically abutted to form a longitudinal beam, and the longitudinal beam can be locked through a certain structure. Then, an external force acts on the corner assembly to make the upper connector 14 and the lower connector 15 respectively rotate in a limited manner along the circumferential direction of the rod body, and at this time, the hinge axis L1 of the upper connector 14 and the lower connector 15 is not parallel to the hinge axis L2 of the upper support platform 11 of the upper rod body 12 and the hinge axis L3 of the lower support platform 11 of the lower rod body 13. And (4) sequentially unfolding and assembling the folding scaffold from top to bottom according to the steps.

According to the technical scheme, the method can be seen. The folding scaffold frame that this scheme adopted realizes folding through articulated mode, and the dismouting is all convenient and has realized the ascending compression of scaffold frame direction of height, and simple structure connection fittings is few, installs, demolishs simple and convenient quick, and the high safe and reliable of degree of mechanization has effectively reduced installation time and recruitment number. Meanwhile, the folding scaffold is recycled, and the transportation space is saved. What is more critical is that compared with the scissor-type supporting scheme, the scheme enables the corner component connecting the upper rod body 12 and the lower rod body 13 to rotate circumferentially on the basis that the folding is realized in a hinged mode for folding. When the circumferential rotation is generated, as described above, since the three hinge axes are not all parallel, the three hinge axes of the upper rod body 12 and the lower rod body 13 are restricted to each other, and a self-locking state is achieved, so that the support state is stabilized. Consequently, this structure has reduced the artifical input and the scaffold installation rate of traditional scaffold by a wide margin to promote the security (let the workman accomplish the scaffold at the one deck and build the task), and promoted foldable scaffold's support intensity greatly.

In a further preferred embodiment, the circumferential rotation angle range of the upper and lower connecting

members

14 and 15 relative to the lower end of the upper rod 12 and the upper end of the lower rod 13 is 90 °. When the hinge axis L1 of the upper and lower connecting

members

14 and 15 is perpendicular to the hinge axis L2 of the upper rod 12 relative to the upper supporting platform 11 and the hinge axis L3 of the lower rod 13 relative to the lower supporting platform 11, the upper and

lower rods

12 and 13 are locked in the supporting state. In this embodiment, the circumferential rotation angle range of the upper connecting member 14 and the lower connecting member 15 with respect to the lower end of the upper rod 12 and the upper end of the lower rod 13 is 90 °. In the starting position (rotation angle of 0 °), i.e. the hinge axis L1 of the upper and

lower links

14, 15 is parallel to the hinge axis L2 of the upper rod 12 relative to the upper support platform 11 and the hinge axis L3 of the lower rod 13 relative to the lower support platform 11. In the end position (rotation angle of 90 °), the hinge axis L1 of the upper and

lower links

14, 15 is perpendicular to the hinge axis L2 of the upper rod 12 relative to the upper support platform 11 and the hinge axis L3 of the lower rod 13 relative to the lower support platform 11. Due to the vertical hinge axis, the turning of the upper connecting piece 14 and the lower connecting piece 15 is completely locked, and the stability is achieved.

The upper connecting piece 14 and the lower connecting piece 15 both comprise

rotating shaft parts

14a and 15a and hinged parts, rotating shaft cavities 12a and 13a are arranged at the lower end part of the upper rod body 12 and the upper end part of the lower rod body 13, and the

rotating shaft parts

14a and 15a of the upper connecting piece 14 and the lower connecting piece 15 are respectively embedded in the rotating shaft cavities 12a and 13a of the upper rod body 12 and the lower rod body 13. According to the technical scheme, the movable part is formed in the upper rod body 12 and the lower rod body 13 (profiles such as square steel) in a mode that the

rotating shaft parts

14a and 15a are embedded in the rotating shaft cavities 12a and 13a, the rotating part is coated and supported, and the strength of the part is improved. Positioning buckle structures are arranged on the inner wall surfaces of the rotating shaft cavities 12a and 13a and the outer wall surfaces of the

rotating shaft parts

14a and 15a, so that the

rotating shaft parts

14a and 15a and the rotating shaft cavities 12a and 13a are locked and positioned at two end values of a rotating range. In this embodiment, the two end values of the rotation range referred to herein mean the start position (rotation angle of 0 °) and the end position (rotation angle of 90 °). The locking and positioning are realized at the position through the positioning buckle structure, and the stability corresponding to two states can be improved. Namely, the external force must unlock the positioning buckle structure first to rotate the corner component. The positioning buckle structure can adopt the retaining wall to limit the rotating angle and adopts a convex and concave matched buckle mode to position.

In order to further improve the assembly efficiency and increase the support stability, the following technical scheme can be combined:
