Description

Technical Field

[0001] The utility model relates to the technical field of building construction scaffold support rods, in particular to a horizontally adjustable disc-type scaffold suitable for high-rise formwork operations. Background Art

[0002] Scaffolding plays an important role in construction. It is a support structure erected on the construction site to facilitate workers' operation and solve problems such as vertical and horizontal transportation. Generally, scaffolding consists of adjustable base, crossbars, vertical poles, connectors and other components. According to the different connectors, scaffolding can be divided into bowl-hook type, wheel-hook type, disk-hook type and other types. Among them, disk-hook scaffolding has better stability and is considered to be one of the most stable systems among load-bearing and non-load-bearing scaffolding. The disk-hook scaffolding has many advantages, including large bearing capacity, high safety, good stability, fast assembly and disassembly speed, wide working space, neat and beautiful appearance, and labor cost saving. Therefore, more and more construction projects have begun to widely use disk-hook scaffolding.

[0003] With the rapid development of the construction industry, the demand for large-scale frame structures continues to increase, so high-support formwork installation and construction technology has been widely used. As a commonly used construction process, high-support formwork is convenient, fast, safe and reliable, and plays an important role in the construction of large-scale frame structures. However, high-support formwork technology requires strong bearing capacity while ensuring safety and stability. The disc-type scaffolding is preferred for high-support formwork installation due to its many advantages. However, since the horizontally connected crossbars of the traditional disc-type scaffolding are produced according to a certain module length, the spacing between the vertical poles must correspond to it when used on site. For irregular building structures such as arcs, when arranging their formwork, support frame and external scaffolding, the spacing between the scaffolding vertical poles is different in length, so the conventional disc-type scaffolding system does not meet the use requirements. In addition, when the current disc-type scaffolding is erected at the corners, the crossbars are too long or insufficient, and small crossbars and ordinary fasteners need to be used separately to tie, resulting in reduced integrity and stability of the frame.

[0004] Therefore, how to improve the existing disc-type scaffolding to meet the diverse needs of construction sites, adapt to the layout of scaffolding in irregular building structures, solve the problems existing in the erection of corners, and ensure the integrity and stability of the tall formwork operation structure is still an urgent problem to be solved.

DETAILED DESCRIPTION

[0027] The following will be combined with the embodiments and drawings to clearly and completely describe the technical solution of the utility model.

[0028] This embodiment is a horizontally adjustable disc-type scaffolding for tall formwork operations, which is proposed in response to the existing disc-type scaffolding that cannot meet the diverse needs of construction sites, cannot adapt to the scaffolding layout of irregular building structures, and has problems in erecting corners. In order to achieve the function of adjusting the length of the crossbar, this embodiment designs the crossbar into an inner and outer sleeve form, and designs a mechanism for adjusting the docking position of the inner and outer sleeves. The relative position of the inner and outer sleeves is adjusted through the positioning pin structure to change the length of the crossbar to adapt to different needs and environments. The details are as follows:

[0029] like Figures 1 to 6As shown, the disc-type scaffolding includes a vertical pole 1 and a cross bar 3 connected between two vertical poles 1 through a connecting plate 2; the cross bar 3 includes an inner sleeve 31 and an outer sleeve 32; the inner sleeve 31 is divided into two sections, one end of which is fixed to the connecting plate 2 through a joint assembly 4, and the other end is sleeved in the outer sleeve 32 through a positioning pin structure 5; and the inner sleeve 31 can be telescopically adjusted in the outer sleeve 32 to achieve horizontal adjustment of the length of the cross bar 3. This adjustment mechanism makes the disc-type scaffolding more flexible and adaptable, effectively adjusts the horizontally connected cross bar module length, and is more flexible for arc-shaped and irregular building structure templates and their supporting frames and external scaffolding, thereby improving construction efficiency; in addition, it solves the risk caused by too long or insufficient cross bars when setting up corners of the disc-type scaffolding, and effectively improves the integrity and stability of the frame.

[0030] The working principle of the horizontally adjustable disc-type scaffolding described in this embodiment is based on the interlocking principle between the disc and the frame. When the disc is connected to the frame, the teeth between them will bite each other to form a strong connection. This interlocking mechanism enables the disc frame to withstand large tensile forces and resist certain shear forces and torques. In this embodiment, the connecting disk 2 is an annular disk, which is sleeved on the vertical pole 1, and a plurality of connecting holes 21 are distributed along the disk; the joint assembly 4 at the end of the inner sleeve 31 includes a joint body 41 and a wedge pin 42; the joint body 41 is a wall clamp structure of a U-shaped design, wherein a mounting notch 43 matching the thickness of the disk is provided in the middle thereof, and a locking channel 44 connected to the connecting hole 21 on the connecting disk 2 is provided on the upper and lower wall panels of the joint body 41; the wedge pin 42 passes through the locking channel 44 of the upper wall panel of the joint body 41, the connecting hole 21 on the connecting disk 2, and the locking channel 44 of the lower wall panel of the joint body 41 from top to bottom in sequence, and then the inner sleeve 31 is engaged and connected with the connecting disk 2 to be fixed.

The marble buckle 51 can be a press-in spring plunger 6 or an in-tube marble positioning spring sheet, preferably a press-in spring plunger 6. The clamping holes 52 are at least one row, which are arranged on the side wall of the outer sleeve 32 at a certain interval. The press-in spring plunger 6 includes a plug seat 61 and a spring column 62; the plug seat 61 is a cross-shaped support casting, and its size is just enough to be plugged into the tube cavity of the inner sleeve 31. When in use, since the corresponding clamping hole of the inner sleeve is designed at the tail, the press-in spring plunger can be easily clamped, and then the spring plunger is welded to the inner wall of the inner sleeve for stability. There is at least one spring column 62, which is embedded in the support end of one of the plug seats 61. A spring column hole 63 is provided at the corresponding position of the inner sleeve 31.
