Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of concrete steel formwork, in particular to a modular steel formwork and an installation ladder thereof. BACKGROUND

[0002] Concrete structures play a crucial role in the field of civil engineering, and concrete formwork engineering is an unavoidable construction phase of concrete structures. Concrete formwork is generally divided into wood formwork and steel formwork, among which wood formwork is widely used due to its low cost, easy processing, and convenience of processing. However, with the national emphasis on infrastructure construction, more and more super projects are emerging, and structures with super span, super volume, and super height are increasing, making it difficult for wood formwork to meet the requirements. Therefore, the application of steel formwork is becoming more and more widespread.

[0003] Chinese patent CN118087845A discloses a steel formwork with detachable panels and scattered assembly and support, relating to the technical field of steel formwork, comprising multiple edge frames, multiple short middle frames, and multiple connecting angles one. The end intersection of the same group of two adjacent edge frames and short middle frames and the end intersection of the same group of two adjacent middle frames and short middle frames are fixed with connecting angles one through bolts. The front and rear sides of the frame are installed with panels. The intersection position of the edge frame and the panel and the intersection position of the middle frame and the panel are also installed with connecting angles one. The connecting angles one and the panels are connected through self-tapping screws.

[0004] Traditional steel formwork is fixed in shape and size, which is good for its application in engineering, but it is expensive, requires a large amount of labor, and cannot be recycled. After a project is completed, it loses its value. Although the steel formwork disclosed in Chinese patent CN118087845A can improve the recycling rate of steel formwork, it has many steps for installation and disassembly, is prone to deformation, has a large amount of work, and has low adaptability to special-shaped concrete components.

[0011] The standard connecting piece is 8 kinds.

[0012] The standard connecting piece is provided with a hole, and the standard connecting piece can be penetrated into the opposite pull bolt through the hole.

[0013] The installation ladder of the modular steel formwork comprises an installation ladder, and the installation ladder is a semi-cylindrical shape, which can be placed on the main ridge of the V-shaped steel formwork standard part, so that the connection between the ladder body and the steel formwork standard part is facilitated.

[0014] The present application has at least the following advantages:

[0015] 1. The present application solves the problem of low adaptability of the steel formwork by using steel formwork standard parts of different sizes and standard connecting pieces of different forms.

[0016] 2. The present application solves the problem of large volume and heavy weight of the steel formwork by using steel formwork standard parts of different sizes.

[0017] 3. The present application solves the problem of difficult connection and inconvenient installation of the steel formwork by using standard connecting pieces and installation ladders. DETAILED DESCRIPTION
