Description

Technical Field

[0001] The utility model relates to the field of construction engineering, in particular to an unsupported connection node between plate strips of assembled building composite panels. Background Art

[0002] At present, after the prefabricated composite slab is hoisted into place and the elevation is corrected, the hanging formwork construction technology is used at the slab position, and the slab formwork frame system is established, the steel bars are tied, and the concrete is poured according to the design requirements. When the concrete strength reaches the requirements of the construction specifications, the formwork and formwork system are removed to complete the construction.

[0003] Although there are many construction methods for the construction of composite slab strips, the formwork system of the slab strips uses a lot of frame materials, which increases the construction cost. The frame materials are difficult to install and the turnover is unchanged. In addition, the supporting effect of the existing formwork frame system is not good enough, and the load capacity is not strong, which cannot guarantee the forming quality of the composite slab strips.

[0004] Therefore, it is necessary to design an unsupported connection node between the plate strips of the prefabricated building composite slab to overcome the above problems. Utility Model Content

After the installation is completed, the template at the composite plate strip can be effectively supported without other reinforcement.

[0018] 3. The unsupported connection nodes between the composite slabs of the prefabricated building provided by the utility model can make full use of the composite slabs' own tensioning, and there is no need to set a support frame under the slab. At the same time, the connection nodes meet the bearing capacity requirements, are easy to install and easy to turn around, and the connection node components have strong load capacity and a large vertical load, which can ensure the molding quality of the composite slabs and avoid leakage and looseness.
