[0001] The utility model belongs to the technical field of underground garage construction, in particular to a membrane shell used for underground garage construction. Background Art
[0002] During the construction of an underground garage, in order to reduce the cost of construction, the formwork will be erected first, followed by the installation of column formwork and the laying of wooden keel supports. After that, the formwork will be laid on the top of the wooden keel supports, and the formwork shell will be installed. Finally, the bundled steel bars will be laid and the concrete will be poured. By setting up the formwork shell, the volume of concrete that needs to be poured can be reduced, thereby reducing the weight of the underground garage roof and improving the stability of the underground garage after construction.
[0003] After the membrane shell is installed, two adjacent membrane shells are generally connected, and then the steel mesh is laid and concrete is poured. However, a large impact force will be generated when pouring concrete, which can easily disperse the constructed membrane shell, causing the center of gravity of the underground garage roof to shift. In addition, the membrane shell and the post-poured concrete lack a connection structure, which makes it easy for the concrete layer and the membrane shell layer to separate and delaminate, thereby affecting the service life of the underground garage. Therefore, it is necessary to design a membrane shell for underground garage construction to solve the above problems. Utility Model Content
