At present, there has been a concrete application of assembled wallboard in the building field, for example, a building steel structure assembled wallboard disclosed in chinese patent No. ZL201720506773.6, includes a fixed connection plate, the fixed connection steel sheet is connected with reinforced wallboard main part through welding, and has bolted connection hole through drill bit processing on the fixed connection steel sheet, the inside of reinforced wallboard main part is connected with the reinforcing bar through welding, the inside packing of reinforced wallboard main part has filled concrete, both sides are connected with protective rubber pad through fastening bolt around the reinforced wallboard main part. The assembled wallboard does not consider the overlapping treatment between two adjacent wallboards and the reliable connection between the wallboards and the main structure, and only considers the strength of the wallboards, so that the assembled wallboard meets certain strength and simultaneously considers the weight reduction of the wallboards and the increase of the thermal performance of the wallboards, such as heat preservation, heat insulation and the like, as far as possible.
Meanwhile, as for the leakage prevention method of the joint of the prefabricated and assembled type industrialized outer wallboard disclosed in the Chinese patent No. ZL201610803173.6, a connecting edge groove is arranged at the edge of the outer wallboard, and the joint of two adjacent outer wallboards is filled in the complete joint groove formed by joint mixture so as to prevent the leakage of rainwater at the joint. However, since the caulking agent is in an outdoor environment, cracks are inevitably generated due to shrinkage deformation, which affects the anti-seepage effect.
At present, the research on prefabricated wallboard is relatively more, and the content of the steel structure assembled wall body adopting bolts, screw holes and wallboards, the structure of the assembled wall body adopting I-shaped steel beams and the like is found. However, many problems still exist in that the connection is unstable and the assembly analysis is incomplete. For example, Chinese patent number ZL201610297096.1, the application publication date is 2016, 7 and 27, and the invention and creation names are as follows: the utility model provides an at prefabricated wall panel and steel construction combination's outer wall body, the outer wall body that this application relates to comprises shaped steel post, shaped steel roof beam and prefabricated wall panel, prefabricated wall panel contains reinforced concrete rib, interior wallboard or side fascia, the side of reinforced concrete side rib be equipped with and expose the reinforcing bar, utilize to expose reinforcing bar and shaped steel post and carry out welded connection. In the application, the exposed steel bars are welded with the section steel, so that the difficulty of site construction is increased, and the welding quality is not easy to guarantee; the inner and outer wallboards are formed by pouring the ribbed steel mesh body and concrete, so that the requirement on the manufacturing process of the wallboards is high, and the cost is increased; in addition, the prefabricated wall panel does not consider the connection with the bottom foundation.
Therefore, places needing improvement and continuous improvement exist in the aspects of the structure, the node connection, the anti-seepage treatment of joints and the like of the prefabricated wall panel, for example, the research on the steel structure assembly type external wall panel is only limited to the node connection of the wall panel and steel beams and steel columns of middle floors, and the whole longitudinal connection system of the wall panel, a foundation, steel beams in middle floors, steel beams of a roof truss and the like is not researched systematically; on the other hand, few researches are made on the connection of waterproof and impervious joints of two adjacent wallboards in the horizontal direction, and how to improve the thermal insulation performance of the wall body while reducing the weight of the external wallboard.
