Description

Technical Field

[0001] The utility model relates to the technical field of construction tools for building engineering, in particular to a reusable spliced ​​combined steel template. Background Art

[0002] Steel formwork is a steel formwork used for concrete pouring. In addition to steel formwork, there are also wooden formwork, plywood formwork, etc. Steel formwork is widely used in construction projects for its multiple uses and beautiful concrete pouring.

[0003] At present, in order to resist strong wind loads and earthquake forces, settlement joints are inevitably set up in building structures in some areas to prevent the occurrence of problems such as cracking and tilting of the building as a whole due to uneven settlement of the foundation. The settlement joints are generally constructed by embedding extruded boards in the middle, which makes it difficult to support the formwork, easily leading to poor construction quality at the settlement joints and difficulty in subsequent demolding.

[0004] CN 218779935 U discloses a steel formwork device for settlement joint construction, which includes an upper support steel formwork and a lower support steel formwork with the same structure, and the upper support steel formwork and the lower support steel formwork are assembled together at the settlement joint. The lower support steel formwork includes a large plate, and a vertical keel with a triangular structure is welded on both sides of the back of the large plate. A plurality of horizontal flat keels are evenly welded on the back of the large plate. A plurality of fixed card slots for placing and fixing short bars are arranged on the top of the large plate, and the fixed card slots are tightly sealed by inserting fixed cover plates. In actual use, the vertical keels between the lower support steel formwork and the upper support steel formwork are pressed against each other to fill the settlement joint. The device solves the problems of conventional wooden formworks being difficult to install and dismantle, difficult to reinforce, and using extruded boards for filling, resulting in poor quality of concrete structure molding and easy mold running. The device has a fast construction speed and is not affected by concrete vibration. However, the following problems still exist during its use: 1. It is unable to adjust its own width according to the width of the settlement joint, has poor adaptability and limited use; 2. After the concrete is poured and shaped, it is inconvenient to remove the lower supporting steel formwork due to the interference of the fixed short bars. Utility Model Content
