Description

Technical Field

[0001] The utility model relates to an adjustable connecting device. Background Art

[0002] In order to meet the requirements of green energy saving, low carbon and environmental protection, prefabricated buildings are now more and more widely used. There are both reinforced concrete prefabricated structures and steel prefabricated structures. Compared with the two prefabricated structures, reinforced concrete prefabricated structures are cheaper and have better fire resistance, but the construction period is long. Steel prefabricated structures have a short construction time, but are more expensive and have poor fire resistance. Therefore, some building designs use a mixed frame structure of reinforced concrete and steel structures, such as frame columns and frame main beams use reinforced concrete, but frame secondary beams use steel structures.

[0003] For this kind of structure, the traditional construction method is: in the process of tying the steel bars of the reinforced concrete frame main beam, the embedded parts of the frame steel structure secondary beam are installed in an interspersed manner. After the concrete of the frame main beam is poured and cured, the formwork is removed to expose the embedded parts. After measuring and laying out, the frame steel structure secondary beam is hoisted, and the frame steel structure secondary beam and the embedded parts are connected with the connecting plate. Then the floor deck and steel bars on the upper part of the steel beam are laid, and then the floor slab concrete is poured. The disadvantages of this construction method are: 1. The frame steel structure secondary beam needs to be cured to reach the strength before it can be installed; 2. Concrete needs to be poured twice, that is, once for the reinforced concrete frame main beam and once for the floor slab.

[0004] In addition, when installing the secondary beams of the frame steel structure, the position is easily shifted, causing the connection position of the frame steel secondary beams on the same floor to be disturbed and shifted when pouring concrete, which in turn requires reinstallation, consuming a lot of time.
