Referring to fig. 1, the outline of a building 100 is comprised of four sides and four corners. On floors 4-59 of the building 100, the four sides are flat and the contour of the upper and lower floors 100 is consistent. From 60 floors to 66 floors of the building 100, the four side surfaces are all adduction curved surfaces, the radian of the curved surfaces is gradually increased along with the increase of the number of the floors, and the outlines of the upper and lower buildings 100 are changed and have a certain inclination angle.

Example 1

Referring to fig. 2 and 3, the present embodiment provides a climbing frame protection structure for protecting an external structure 100, especially an external structure 100 with a special-shaped curved surface. The climbing frame protection structure includes a climbing frame unit 200, a fixing unit 300 (see fig. 6), a guiding unit 400, and an adjusting unit 500 (see fig. 7), wherein the climbing frame unit 200 serves as a protection body. The guide unit 400 is connected to the building 100 by the fixing unit 300, and guides the creeper unit 200 when the creeper unit 200 is lifted. The adjusting unit 500 can adjust the angle of the guiding unit 400 to prevent the guiding unit 400 from jamming the climbing frame unit 200 during the guiding process.

Referring to fig. 2 to 5, in particular, the rack climbing unit 200 includes a rack body 210 and a flap assembly 220. The plurality of frame bodies 210 are arranged along the circumference of the building 100, and the flap assemblies 220 are arranged between two adjacent frame bodies 210. The height of the frame body 210 is equal to the height of the four-story half-building 100, as in the conventional climbing frame.

In the present embodiment, the number of the rack bodies 210 is twelve. Four of the frame bodies 210 are respectively located at four top corners of the building 100, and the remaining eight frame bodies 210 are grouped into two and respectively located at four side surfaces of the building 100.

When the bottom of support body 210 is less than 59 floors of building 100, each support body 210 is in vertical state, and two adjacent support bodies 210 butt, turn over board assembly 220 and pack up, whole climbing frame unit 200 vertical lift. Wherein, the two frame bodies 210 on any side of the building 100 are located on the same vertical plane.

When the bottom ends of the shelves 210 rise to the 59 stories of the building 100, the respective shelves 210 are separated from each other. The frame body 210 at the top corner of the building 100 is still kept in a vertical state and is vertically lifted. The frame body 210 of the side of the building 100 is inclined and ascends and descends in an inclined manner as the side is contracted layer by layer. After each frame body 210 is lifted and lowered, the flap assembly 220 is unfolded to connect two adjacent frame bodies 210. In addition, the two frame bodies 210 on either side of the building 100 are folded toward the side of the building 100 at the connection position and arranged in a V-shape.

In a word, the climbing frame unit 200 is split into a plurality of frame bodies 210 by using the principle that a polygon is infinitely close to a circular arc, and the direction of each frame body 210 can be consistent with the outline of the building 100 by adjusting part or all of the frame bodies 210.

Specifically, the frame body 210 includes a side guard plate 211, a walkway plate 212, and a skeleton 213. The framework 213 is assembled by long cross bars, short cross bars, vertical bars, diagonal bars and other structures, and the side guard plates 211 and the walkway plates 212 are both laid on the framework 213 and fixed by the framework 213.

When two adjacent frame bodies 210 are abutted, the side guard plates 211 on the two frame bodies 210 are spliced into a whole, and the walkway plates 212 on the two frame bodies 210 are spliced into a whole. In contrast, when two adjacent frame bodies 210 are separated, a gap is formed between the side guard plates 211 on the two frame bodies 210, and a gap is also formed between the walkway plates 212 on the two frame bodies 210. The gap is shielded by the flap assembly 220 to ensure the integrity of the shield.

In the present embodiment, the flap assembly 220 is composed of a first flap 221 and a second flap 222. The first flap 221 is unfolded when two adjacent shelves 210 are separated, and is connected to the side guard plates 211 of the two shelves 210. The second flap 222 is unfolded when two adjacent shelves 210 are separated and connects the walkway plates 212 of the two shelves 210.

In one embodiment of this embodiment, the first flap 221 is hingedly connected to the frame 213 of one of the shelves 210 and is removably connected to the frame 213 of the other shelf 210 when deployed. The second flap 222 is hinged to the walkway plate 212 of one of the shelves 210 and when deployed overlaps the walkway plate 212 of the other shelf 210 and remains stable under the influence of gravity.

Referring to fig. 6 and 7 together, in particular, the fixing unit 300 is composed of an attachment holder 310 and a fixing bolt 320. The attaching support 310 is fixedly connected with the floor of the building 100 by the fixing bolt 320, and the guide unit 400, the electric hoist, the top brace and other structures are all arranged on the attaching support 310 and fixed by the attaching support 310.

In this embodiment, the fixing bolt 320 vertically penetrates through the floor slab, and both ends of the fixing bolt are sleeved with nuts.

In another embodiment of the present application, the fixing bolt 320 may also be pre-buried in the floor slab.

Specifically, the guiding unit 400 is a conventional guiding seat, a guiding wheel is rotatably disposed on the guiding seat, and a guiding rail is correspondingly disposed on the frame body 210.

The frame body 210 is in sliding fit with the guide seat through the guide rail and the guide wheel, and the guide seat guides the frame body 210 in the lifting process of the frame body 210, so that the position deviation of the frame body 210 is prevented.

Specifically, the adjusting unit 500 is provided at the connection of the guide unit 400 and the attaching bracket 310, and adjusts the angle of the guide unit 400 to match the inclination angle of the outline of the building 100.

When the inclination angle of the outline of the building 100 is zero, the frame body 210 is vertically lifted, the angle of the guide unit 400 is the same as that of the guide seat in the conventional climbing frame, and the frame body 210 is guided during the lifting of the frame body 210.

When the inclination angle of the profile of the building 100 is not zero, the frame body 210 is inclined as the side surface of the building 100 is gradually retracted layer by layer, the guide unit 400 is inclined by a certain angle under the adjustment of the adjustment unit 500, and the frame body 210 is guided in the process of inclined elevation of the frame body 210.

Compared with the guiding unit 400, the chain of the electric hoist is a flexible part, and the top support can rotate freely, so that the angle of the structures such as the electric hoist and the top support does not need to be adjusted independently.

In the present embodiment, the adjusting unit 500 is a pad. The pad plate is disposed between the guide unit 400 and the fixing unit 300 and at the lower portion of the guide unit 400, and the top of the guide unit 400 is coupled to the attaching bracket 310.

The guide unit 400 may be inclined at a certain angle by inserting the backing plates, and the inclination angle of the guide unit 400 may be adjusted by changing the number and thickness of the backing plates.

In another embodiment of the present application, the adjusting unit 500 is an adjusting lever. The adjusting rod is horizontally disposed and directed to the frame body 210 by the attaching bracket 310. The adjusting rod is inserted into the attaching support 310, and is in threaded fit with the attaching support 310, and one end of the adjusting rod facing the frame body 210 is abutted against the lower portion of the guide unit 400.

The adjustment rod is screwed so that the adjustment rod is not positioned in the attachment holder 310, and the angle of the guide unit 400 is the same as that of the guide holder of the conventional climbing frame, so that the frame body 210 can be guided in the vertical lifting process of the frame body 210. The inclination angle of the guide unit 400 can be changed by extending the adjustment lever from the attaching bracket 310 and pushing the lower portion of the guide unit 400 away from the attaching bracket 310.

In this embodiment, the top of the guide unit 400 is bolted to the attachment bracket 310. The connection structure of the guide unit 400 and the attachment bracket 310 is simple and stable, but the nut needs to be loosened when the angle of the guide unit 400 is adjusted and tightened again after the adjustment is completed.

In another embodiment of the present application, the top of the guide unit 400 is hinged with the attachment bracket 310. The coupling structure of the guide unit 400 and the attaching bracket 310 is relatively complicated, but other adjustments are not necessary to adjust the angle of the guide unit 400, which can simplify the operation.

Further, the attachment base 310 is provided with a plurality of bolt holes for the fixing bolts 320 to pass through, and the bolt holes are arranged along the connecting line direction between the attachment base 310 and the frame body 210.

When the frame 210 is inclined, the frame 210 is still spaced from the building 100 properly. At this time, the position of the attachment bracket 310 may be adjusted along the arrangement direction of the bolt holes, so that the attachment bracket 310 may be extended out of the building 100, thereby adjusting the distance between the structures, such as the guide unit 400 and the frame body 210, and the building 100.

In the use process of the above-mentioned climbing frame protection structure, when the bottom of the building 100 with a regular profile is constructed, the flap assembly 220 is retracted, so that the two adjacent frame bodies 210 are abutted, and the whole climbing frame unit 200 is vertically lifted under the guidance of the guide unit 400. When the top of the building 100 having the layer-by-layer adduction curved surface is constructed, the frame bodies 210 are separated from each other, the direction of each frame body 210 is kept consistent with the outline of the building 100, and then the angle of the guide unit 400 is adjusted by the adjusting unit 500 to match the inclination angle of the outline of the building 100, so that each frame body 210 is respectively and obliquely lifted. After the frame body 210 is obliquely lifted, the turning plate assembly 220 is unfolded, the area left between the two adjacent frame bodies 210 is filled when the turning plate assembly 220 is connected with the two adjacent frame bodies 210, and the protection function of the whole climbing frame protection structure is ensured. Therefore, the climbing frame protection mechanism can be used for normally ascending, descending and protecting against irregular curved surface changes of the building 100.
