Wherein the module structure frame includes at least an outer frame 1, and an out-of-plane end of the outer frame 1 is formed with a bite (hereinafter, implemented as an out-of-plane member 11 in fig. 6). The high-performance concrete slab 2 is molded in the outer frame 1 and covers the outer end of the surface of the outer frame 1 to form a continuous edge sealing, so that a complete waterproof surface is formed, and the engaging part is buried and engaged in the high-performance concrete slab.
The term "edge seal" is interpreted as that the outer frame 1 is formed by a continuous steel structure, and the outer end of the outer frame is wrapped by the high-performance concrete slab 2 to form a waterproof edge seal, which is more beneficial to forming a complete waterproof surface.
The high performance concrete slab 2 in this embodiment is implemented as a concrete slab with fibre hybrid casting or UHPC slab.
The outer frame 1 is a structural frame, the shape of which is a regular square shape, and in the present embodiment, it is implemented as a rectangular structural frame, and is composed of four frame sides. In combination with the above, the outer end of each frame edge is formed with the engaging portion which is buried and engaged in the high-performance concrete slab 2, so that the high-performance concrete slab 2 covers the outer end of the frame edge to form a flat outer decorative surface. The outer frame and the high-performance concrete slab can form a combined integral structure, the out-of-plane bending rigidity of the whole wallboard is greatly increased, and meanwhile, the wallboard is formed into a continuous surface with larger thickness by one round around, so that the waterproof structure is convenient to finish.
Further, referring to fig. 2, a forming space is formed in the outer frame 1, the high performance concrete slab 2 is formed in the forming space, and the thickness of the high performance concrete slab 2 in the forming space is smaller than the thickness of the forming space. Since the high performance concrete slab 2 is close to the out-of-plane end of the outer frame 1, the difference in the thickness of the space formed on the in-plane side can be used as the insulation layer 3 or structural reinforcement. Specifically, the inner side of the high-performance concrete slab 2 forms a heat insulation space, and the heat insulation space at least comprises a heat insulation layer 3.
As described above, referring to fig. 4, 5 and 6, the outer frame 1 is formed by surrounding a plurality of frame edges, the frame edges are in a groove structure, and the notch faces the forming space. Further, the channel structure includes at least an exterior surface member 11, an interior surface member 12, and a connecting member 13, the connecting member 13 being connected to the exterior surface member 11 and the interior surface member 12, and the engagement portion being defined as the exterior surface member 11.
It should be noted that the structure of the out-of-plane member 11, the in-plane member 12 and the connecting member 13 may be implemented as a single plate, a flat tube, etc. in order to provide structural support, on the one hand, to facilitate the formation of the high performance concrete slab 2 and, on the other hand, to facilitate the assembly and connection with the main building.
As a preferred embodiment of the present embodiment, the out-of-plane member 11 is an out-of-plane plate, the in-plane member 12 is an in-plane plate, and the connecting member 13 is a connecting plate. Further, through holes or saw tooth sections or wave sections which are embedded and meshed with the high-performance concrete slab 2 are arranged on the surface outer plate. Further, the outer panel may be a single panel, a double panel, or multiple panels, for the purpose of improving the bite strength and the force-receiving capability. Through holes or saw tooth sections or wave sections arranged on the surface outer plates can further improve the bonding capability with high-performance concrete.
Referring to fig. 2 and 3, in order to facilitate the forming and structural reinforcement of the high performance concrete slab 2, the present embodiment further includes a structural net 16, the structural net 16 is disposed in the outer frame 1, and the structural net 16 is fixedly connected to the connecting members 13 of the outer frame 1. Preferably, when the connecting piece 13 is a connecting plate, the edge of the structural net 16 is bent to form a connecting surface which is attached to the connecting plate, and then the welding and fixing can be completed, so that the welding and fixing device is simple and convenient.
As shown in fig. 2, one side of the outer frame 1 is used as a connection part with a main structure (upright 5 or steel beam), and a heat insulation layer 14 is further arranged on the inner side of the frame edge of the outer frame 1 in order to avoid cold bridge. Preferably, the insulating layer 14 is a heat insulating mat, which is located on the inner panel and serves to block heat transfer therebetween when the inner panel is connected to the pillar 5 by bolt penetration.
Further, referring to fig. 1, 2 and 3, the present embodiment further includes a keel 15, wherein the keel 15 spans between the two frame side panels 12. The keel 15 may be implemented as a C-section steel or truss structure. The outer side of the keel 15 is buried in the high-performance concrete slab 2 to improve the combined stress intensity, and the inner side of the keel 15 is provided with a mounting surface for mounting the indoor decorative plate 4. The mounting surface is provided with mounting holes for mounting the inner decorative plate 4 and other structures. Preferably, the method is used. The fossil fragments are truss structure, and the web member is wave web member, and truss structure's lower chord buries in high performance concrete slab 2. The benefit of using truss structures in the form of wave web members is that the cold bridge is greatly reduced. Similarly, when the C-shaped steel is adopted, a plurality of perforations can be formed in the web plate of the C-shaped steel, so that the reduction of cold bridges is facilitated.
Please combine fig. 2, fig. 3 and fig. 8, in order to reduce the sound transmission between floors in the reinforced concrete structure and improve the sound insulation effect between floors, a sound insulation plate 17 is further disposed in the outer frame in this embodiment, and the position of the sound insulation plate 17 corresponds to the floor 8 of the installation system, so as to isolate the sound transmission between floors.

Specifically, the inner side of the high-performance concrete slab 2 forms a heat insulation space, and the heat insulation space at least comprises a heat insulation layer 3.
