[0002] With the increasing awareness of energy conservation and environmental protection, more and more building walls need to use insulation boards to achieve insulation and energy saving functions. In the prior art, the insulation board structure usually consists of an insulation core material covered with a fireproof reinforcement layer. This structure is prone to bending, breaking, etc. when encountering external force during actual use, and the foam board is easy to fall off, which is prone to safety accidents.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] The purpose of the present invention is to provide a modular truss reinforced concrete self-insulating wall panel to solve the problems existing in the prior art. The self-insulating wall panel of the present invention arranges the insulation material layer in the cavity between the inner blade plate and the outer blade plate in the form of foam, has good air tightness and higher integrity, can achieve the effect of structural insulation integration with the same life span, and also avoids the problem of cumbersome construction and easy falling of the external insulation structure and safety accidents caused by the traditional wall as external insulation; at the same time, the present invention can improve the compression and shear resistance of the self-insulating wall panel by arranging a steel truss structure in the self-insulating wall panel, thereby greatly improving the bearing capacity of the self-insulating wall panel.

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] like Figure 1 to Figure 4As shown, the present embodiment discloses a modular truss reinforced concrete self-insulating wall panel, comprising an inner blade 1, an outer blade 2, an oblique web bar 5 and an insulation material layer 6, wherein the inner blade 1 and the outer blade 2 are both concrete panels. The inner blade 1 and the outer blade 2 are parallel and spaced apart, and the inner blade 1 and the outer blade 2 are respectively provided with inner chord bars 3 and outer chord bars 4, which are both vertically arranged, and in the thickness direction of the modular truss reinforced concrete self-insulating wall panel, the inner chord bars 3 and the outer chord bars 4 correspond one to one. In the inner blade 1 and the outer blade 2, the spacing between two adjacent inner chord bars 3 and two adjacent outer chord bars 4 is 200mm to 250mm. The oblique web bar 5 is in an S-shaped shape from top to bottom, and passes through the corresponding inner chord bars 3 and outer chord bars 4 in turn and is fixedly connected to both. During construction, the diagonal web bar 5 bypasses from the inside of the inner chord 3 and the outside of the outer chord 4 (in this embodiment, the inside direction refers to the direction of the side where the inner blade 1 is located, and the outside direction refers to the direction of the side where the outer blade 2 is located, and it is not that the module truss bar concrete is from the inside of the insulation wall panel as the inside direction, and the module truss bar concrete is from the outer surface of the insulation wall panel as the outside direction); when bypassing the inner chord 3 and the outer chord 4, the bent part in the S-shaped shape is located on the inside of the inner chord 3 or on the outside of the outer chord 4, and the inner annular structure 7 and the outer annular structure 8 are formed between the bent part and the inner chord 3 and the outer chord 4, respectively. Multiple inner annular structures 7 corresponding to the inner blade 1 are arranged horizontally, and multiple outer annular structures 8 corresponding to the outer blade 2 are arranged horizontally. Inner horizontal ribs 9 and outer horizontal ribs 10 are respectively inserted into the inner annular structure 7 and the outer annular structure 8, and then after being positioned by a clamping device, the inner horizontal ribs 9 and the outer horizontal ribs 10 are fixed by welding or binding; thus, the inner chord ribs 3, the outer chord ribs 4, the diagonal web bars 5, the inner horizontal ribs 9 and the outer horizontal ribs 10 constitute a steel truss structure. The thermal insulation material layer 6 fills the cavity between the inner blade 1 and the outer blade 2. The thermal insulation material layer 6 can be a polyurethane foam thermal insulation material, specifically, after the concrete in the inner blade 1 and the outer blade 2 reaches 70% strength, the polyurethane AB material is used to fill the cavity and foam itself.

The diameter of the diagonal web reinforcement 5 is not less than 1 / 20 of the thickness of the thermal insulation material layer 6, so that the diagonal web reinforcement 5 can meet the requirements of coordinated force transmission strength under the axial compression ratio of the inner blade 1 and the outer blade 2 and the in-plane and out-of-plane forces.

[0035] As one implementation mode, the distance between the distal end of the inner annular structure 7 and the inner chord 3 is not less than 20 mm, and the distance between the distal end of the outer annular structure 8 and the outer chord 4 is not less than 20 mm, to ensure that the diameters of the inner horizontal reinforcement 9 and the outer horizontal reinforcement 10 meet the requirements, so as to improve the strength of the steel truss structure.

[0036] As an embodiment, the top of the inner chord bar 3 and the top of the outer chord bar 4 are fixed with a grouting sleeve 11, and the top of the grouting sleeve 11 is exposed from the top of the inner blade 1 and the outer blade 2, and is used for pouring concrete mortar; the bottom of the inner chord bar 3 and the bottom of the outer chord bar 4 are exposed from the bottom of the inner blade 1 and the bottom of the outer blade 2 respectively, and the bottom of the inner chord bar 3 and the bottom of the outer chord bar 4 are used to be plugged into the grouting sleeve 11 in another module truss bar concrete self-insulating wall panel. First, the bottom ends of the inner chord bar 3 and the outer chord bar 4 in the upper module truss bar concrete self-insulating wall panel are correspondingly inserted into the grouting sleeve 11 at the top of the lower module truss bar concrete self-insulating wall panel, and the grouting connection is calibrated and fixed, so as to realize the rapid and firm connection of the upper and lower adjacent wall panels.

[0037] As an implementation method, Figure 4 As shown, the bottom of the inner blade 1 and the bottom of the outer blade 2 are both horizontally provided with concave and convex shrinkage bars 12 to ensure that the horizontal shrinkage compressive shear ductility strength of the reinforced concrete at the bottom of the inner blade 1 and the outer blade 2 is met. Specifically, the distribution of the concave and convex shrinkage bars 12 is within the range of 400mm to 500mm from the bottom end of the inner blade 1 and the bottom end of the outer blade 2 upward, and the distribution range can be selected as 450mm, and the vertical spacing between the two adjacent concave and convex shrinkage bars 12 is 35mm to 55mm, and 50mm can be selected; the diameter of the concave and convex shrinkage bars 12 can be selected as 2.5mm, and the surface is galvanized.
