Description

Technical Field

[0001] The present application relates to the technical field of construction engineering, and in particular to a stair tower system for a circular structure. Background Art

[0002] In circular structure projects, scaffolding is often used as a stair tower system when constructing large circular structures, providing a stable working platform for construction workers, allowing them to carry out walling, plastering, window installation, painting and other operations at height without having to stand directly on the structure of the building. In some cases, scaffolding is also used to support part of the structure of the building, especially when repair or reinforcement work is being carried out, the scaffolding can temporarily bear part of the building weight to ensure construction safety.

[0003] In the prior art, the construction of scaffolding needs to be done layer by layer, and the construction workers stand on the steps of the next layer to build the platform of the next layer. In addition, the position or height of the scaffolding needs to be frequently adjusted around the circumference of the circular structure during the construction process, so the construction and adjustment of the scaffolding may affect the construction progress. When the height of the circular structure construction site is high, the construction of the scaffolding of the corresponding height not only requires more time and manpower, but also poses a threat to the safety of the construction workers during the construction process.

The plurality of connecting plates 431 are distributed along the length direction of the vertical poles 41 and are welded on the vertical poles 41. The buckle joint 432 is welded to the end of the horizontal pole 42. A wedge-shaped pin 433 with a self-locking function is provided at the connection between the buckle joint 432 and the connecting plate 431. The buckle joint 432 of the horizontal pole 42 is connected to the corresponding connecting plate 431 through the wedge-shaped pin 433, thereby realizing the rapid assembly of the support frame 4.

The support base 7 is provided with a lifting assembly 71, which includes a stud 711 and a driving ring 712. The stud 711 is fixedly arranged at the center of the support base 7 along the vertical direction, and a through hole 72 is provided on the steel plate at the bottom of the support base 7 for installing expansion bolts to connect the support base 7 and the ground. The driving ring 712 is threadedly sleeved on the stud 711, and a hand grip 7121 is fixedly arranged on the side wall of the driving ring 712 for the construction personnel to rotate the driving ring 712. The bottom of the vertical pole 41 on the support frame 4 of the starting section 1 is vertically sleeved on the stud 711, and the bottom wall of the vertical pole 41 abuts against the inside of the driving ring 712.

A handle 911 is also fixed on the protective door 91.

[0045] The implementation principle of a stair tower system for a circular structure in an embodiment of the present application is as follows: construction personnel can pre-build the starting section 1, the standard section 2 and the top section 3 on flat ground in a modular manner by using the connecting rods and the buckle joints 432, and then select the number of standard sections 2 as needed. Under the clamping of the lifting equipment, the connecting sleeve 411 is used to perform vertical alignment and limit the vertical poles 41 and the connection between the connecting sleeve 411 and the vertical pole 41 is locked by using the connecting pin and the limiting ring on the connecting pin, so that the stable installation of the standard section 2 and the top section 3 can be realized layer by layer in sequence, and the assembly of the stair tower system can be quickly realized.
