Description

Technical Field

[0001] The utility model relates to the technical field of climbing formwork, in particular to an adjustable climbing formwork auxiliary climbing attachment device. Background Art

[0002] In the construction of super-high-rise vertical structures, climbing formwork technology has been widely used. It has the characteristics of easy operation, simple structure, good stability, safe high-altitude operation and fast climbing speed. Due to its flexible assembly and strong structural adaptability, it can climb vertically as well as along the slope. According to the characteristics of the building structure, the corresponding machine position is designed and a reasonable formwork structure is configured to provide a better working environment for the construction of super-high-rise vertical structures.

[0003] In super high-rise buildings, this type of structure mainly adopts the form of core tube shear wall-external frame steel structure. Among them, as the building height increases, the core tube shear wall is affected by the modeling space and cost and material aspects. After exceeding a certain height, the shear wall in some positions is often converted into connecting beams, so as to achieve the purpose of optimizing the tube space structure and reducing the use of materials such as reinforced concrete. When the climbing formwork frame climbs to a certain height, the cancelled shear wall part cannot be attached to the frame position, affecting the further construction of the structure.

[0004] At present, the traditional construction method for temporary attachment of the core tube climbing formwork frame is to add additional attached concrete shear walls in the area without shear walls or to dismantle and modify the climbing formwork frame. This method leads to a significant increase in construction time and cost, and the added concrete structure needs to be demolished, which does not meet the requirements of green construction.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example:

[0023] See also Figure 1-Figure 4 , an adjustable climbing formwork auxiliary climbing attachment device, comprising a first auxiliary supporting steel column 1, a second auxiliary supporting steel column 2 is arranged at the bottom end of the first auxiliary supporting steel column 1, a first bolt 9 is arranged at the top end of the first auxiliary supporting steel column 1, and the first auxiliary supporting steel column 1 is fixedly connected to the wall through the first bolt 9, a through-wall bolt 3 is arranged through the inside of the wall, a washer 7 is arranged at one end of the through-wall bolt 3, a first gasket 4 is arranged on the outside of the other end of the through-wall bolt 3, a first nut 6 and a second nut 8 are respectively arranged on the outside of the side of the through-wall bolt 3 close to the first gasket 4, a connecting hoop 5 is movably installed on the outside of the bottom end of the first auxiliary supporting steel column 1, a third auxiliary supporting steel column 10 is movably installed on the inside of the top end of the second auxiliary supporting steel column 2, a third nut 11 and a second gasket 12 are respectively arranged on the outside of the third auxiliary supporting steel column 10, and a second bolt 13 is arranged on the outside of the connecting hoop 5.

[0024] In this embodiment, the other end of the second bolt 13 is threadedly connected to the third nut 11 .

[0025] In this embodiment, the bottom end of the first auxiliary supporting steel column 1 is also provided with a first bolt 9 , and is fixedly connected to the top end of the second auxiliary supporting steel column 2 through the first bolt 9 .

[0026] In this embodiment, the bottom end of the second auxiliary supporting steel column 2 is also fixedly connected to the wall.

[0027] In terms of construction difficulties, during the structural construction process, if there is no shear wall on the upper layer, the climbing formwork attachment device needs to be relocated and pre-buried, and the climbing formwork guide rail and the frame need to be dismantled and modified. The present invention can effectively save construction time and improve work efficiency.

[0028] In terms of construction cost, during the structural construction process, if there is no shear wall in the upper layer, it is necessary to add additional concrete shear walls. After the climbing formwork is completed, the added concrete structure is broken down. The present invention can reduce the waste of a large amount of resources and meet the requirements of green construction.

[0029] During the structural construction process, the present invention lays out the installation position of the steel support column, embeds sleeves in the concrete connecting beam and the shear wall according to the drawing, and reserves a lifting ring at the bottom of the upper structure plate at the installation position of the I-beam.

[0030] Before the climbing formwork is lifted, the steel support column, I-beam and through-wall bolts are hoisted to the installation position by a tower crane. During the lifting process, the through-wall bolts are first used to temporarily fix the support and then unhooked. At the same time, the top bolts on the upper and lower parts of the steel support column are tightened to make the steel support and the structure tightly connected. Then, the I-beam is lifted to the designed height by the lifting ring and hand chain hoist, and the support column, I-beam, connecting beam and inner shear wall are connected as a force-bearing whole by bolts. After the installation is completed, the climbing can be carried out; after the climbing formwork is lifted, the auxiliary columns of the same specifications and models can be used for turnover, and the auxiliary columns can also be recycled after the subsequent structural construction is completed.

[0031] Working principle of this embodiment: When in use, the first auxiliary support steel column 1 is connected to the wall by the through-wall bolt 3, and the through-wall bolt 3 is fixed by the first gasket 4, the first nut 6, the washer 7 and the second nut 8 to ensure that the first auxiliary support steel column 1 is fixed, and at the same time, the connection between the first auxiliary support steel column 1 and the second auxiliary support steel column 2 is fixed by connecting the clamp 5, the third auxiliary support steel column 10, the third nut 11, the second gasket 12 and the second bolt 13.
