Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a splicable formwork structure applied to an arc node. Background Technique

[0002] In the field of building engineering, with the increasing complexity and diversification of building designs, the application of arc node structures is becoming more and more widespread. Such structures are particularly common in buildings with circular or arc-shaped structures such as large public buildings, bridges, and stadiums. However, the construction of arc nodes is difficult, and traditional construction methods face many challenges.

[0003] Traditional construction methods include the narrow-strip flat formwork splicing method and the fixed-type steel formwork method: Traditionally, construction workers often use narrow-strip flat formwork to make a full-folded line assembly along the arc, and use a steel bar circular hoop for peripheral positioning. However, this method is prone to local non-circularity, with a wavy appearance and poor forming quality, affecting the overall project quality and aesthetics. To overcome the above problems, some projects will specially manufacture fixed-type steel formwork. Although the accuracy of the fixed-type steel formwork has been improved, the manufacturing cost is high, and it loses its turnover value after completion, resulting in waste of resources and low economic efficiency.

[0004] Therefore, the existing technology has the following defects:

[0005] 1) Low construction efficiency. Traditional construction methods are complex in operation and long in construction period, and it is difficult to meet the requirements of modern building projects for the construction period.

[0006] 2) High cost. Whether it is narrow-strip flat formwork splicing or fixed-type steel formwork, there are problems of high material cost and long manufacturing period.

[0007] 3) Poor forming quality. Due to the limitations of formwork splicing and fixing methods, it is often difficult to guarantee the forming quality of arc nodes, and problems such as formwork bulging and displacement are likely to occur.

[0008] In view of the above deficiencies in the background technique, the market has an urgent need for an arc node formwork device that can overcome these problems, improve construction efficiency, reduce costs, and ensure forming quality. Therefore, it is particularly important to develop a splicable formwork with a simple structure, convenient installation, reusable, and capable of ensuring the forming quality of arc nodes.
