[0032] Application summary:

[0033] The existing steel mesh inner mold wall, for example, the assembly type steel mesh inner mold wall described in "LG assembly type steel mesh mold sandwich thermal insulation system application technology standard", includes keel, steel mesh and mortar outer coating 3.When the distance between the structural columns of the house frame structure is large in large span (i.e.for super wide wall), a large number of keels need to be set when using the wall, and the keel generally adopts c-shaped steel, channel steel and other profiles, which only plays a supporting role in structure, and does not form a force transmission whole, that is, when the super wide wall, the shear capacity of the wall is not particularly improved, so in the application, structural columns need to be set between the frame columns, and large-span wall surface cannot be formed.

[0034] Structural embodiment:

[0035] Please refer to Figures 1-5 The embodiment provides a large-span anti-seismic hollow steel mesh inner mold wall body, which comprises a corrugated inner mold steel mesh 1, a truss 2 and an outer coating 3, wherein the corrugated inner mold steel mesh 1 forms a forming surface on the outer side, the outer coating 3 is formed on the forming surface, the forming surface of the corrugated inner mold steel mesh 1 forms a hollow groove 10 continuously formed along the span direction, at least one hollow groove 10 is vertically provided with the truss 2, and the truss 2 has an abdominal structural member which is force-transmitted to the groove edge of the hollow groove 10.

[0036] In this embodiment, the truss 2 can adopt various structural forms. Its main purpose is to improve the strength of the groove surface structure of the corrugated inner mold steel mesh 1 through the web structural members of the truss 2. In this embodiment, for ease of description, as follows... Figure 3 As shown, the following example uses the outer protrusion of the wave-shaped inner mold steel mesh 1 as a trough 12 and the inner protrusion as a peak 11.

[0037] Please see Figure 3 and Figure 4 The hollow groove 10 formed at the crest 11 is filled with the outer covering layer 3, and the truss 2 is set in the hollow groove 10 formed at the crest 11 and is filled with the outer covering layer 3 to form a steel-concrete structure.

[0038] Specifically, the truss 2 includes at least an upper chord 21, web members 22, and a lower chord 23, with the web members 22 serving as the web structure. These web members 22 are attached to the hollow groove 10 and can be further secured by binding or welding, thus forming a rib structure effect on the surface of the hollow groove 10, further enhancing the structural strength. In the construction field, a conventional truss 2 is a rigid structure composed of geometrically invariant triangular units, with the members primarily bearing axial tension and compression, resulting in high structural efficiency. It often plays a crucial role in cantilever and spanning spatial structures. This application, for the first time, uses the truss 2 as a support, strengthening the corrugated inner mold steel mesh 1 through its web members 22, and combining them to form a skeleton.

[0039] Furthermore, the truss 2 is implemented as a triangular truss 2, with the web members 22 of the triangular truss 2 respectively abutting against the edge of the hollow groove 10.

[0040] Alternatively, planar trusses 2 can be used. For example, two planar trusses 2 can be attached to the two surfaces of the hollow trough 10 respectively, and welded to the top to form a triangle;

[0041] Alternatively, three planar trusses 2 are welded together to form a spatial triangular prism structure, with at least two planar trusses 2 abutting against the two surfaces of the hollow trough 10 for trough surface reinforcement.

[0042] In this embodiment, Figure 2 As shown, taking the triangular truss 2 as an example, the position of the upper chord 21 of the triangular truss 2 corresponds to the bottom of the hollow groove 10, and the web member 22 is attached to the edge of the hollow groove 10.

[0043] Furthermore, the corrugated inner mold steel mesh 1 is preferably a corrugated steel mesh sheet, and its material is steel. The truss 2 can be welded or tied to the corrugated inner mold steel mesh 1.

[0044] Please see Figures 1-5When the embodiment is a double-wall structure, the wave-shaped inner mold steel mesh 1 is two rows, and the hollow grooves 10 of the two rows of wave-shaped inner mold steel meshes 1 are oppositely arranged in sequence; at least in the two hollow grooves 10 opposite to each other at one position of the two rows of wave-shaped inner mold steel meshes 1, one group of trusses 2 is arranged, respectively, and the two groups of trusses 2 are located at the same position and oppositely arranged to form a hidden column structure. When the width of the wall is larger, the number of trusses 2 can be set by setting the number of hidden columns to correspond to the number of trusses 2. Further, the two rows of wave-shaped inner mold steel meshes 1 can be connected to each other, and the outer cover layer 3 is formed on the outer forming surface of the two rows of wave-shaped inner mold steel meshes 1. Specifically, the two rows of wave-shaped inner mold steel meshes 1 are connected to each other by conventional tension bolts, and the two ends of the tension bolts are located in the outer cover layer 3 on both sides to form a bolt connection. The position of the tension bolt can be located at the wave peak or wave trough of the wave-shaped inner mold steel mesh 1, which is a conventional way and will not be described in detail here.

[0045] The embodiment has the following beneficial effects:

[0046] Compared with the traditional steel mesh hollow inner mold wall, the truss 2 and the wave-shaped inner mold steel mesh 1 form a framework, which increases the stiffness of the wall, and the web structure of the truss 2 and the wave-shaped inner mold steel mesh 1 transmit shear force. After pouring the outer cover layer 3, the stiffness and seismic strength of the wall can be further improved, so that when the structural column span is large, the wall can be installed without the need for additional structural columns, thereby being suitable for large-span walls and saving steel and concrete.

[0047] The triangular truss 2 is adopted, and the triangular structure of the web 22 is matched with the two side grooves of the hollow groove 10. The structure of the web 22 is attached to or fixed to the groove side to form a rib structure effect of the groove surface, thereby further improving the structural strength of the wave-shaped inner mold steel mesh 1, and thereby the height of the wall can be increased.

[0048] When the wave-shaped inner mold steel mesh 1 of the utility model is two rows, and the two rows are formed into the outer cover layer 3, a double-wall structure is formed, and the hollow groove 10 opposite to the forming surface of the wave-shaped inner mold steel mesh 1 forms a hidden column of the wall. The number of trusses 2 can be appropriately set according to the width (i.e. span) of the wall, which meets the stiffness requirement of the large-span wall.

[0049] Further, the embodiment of the utility model is described in detail in combination with the drawings, and those skilled in the art can make various changes to the utility model according to the above description. Therefore, some details in the embodiment should not constitute a limitation on the utility model, and the protection scope of the utility model will be defined by the appended claims.
