DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-3 This application is described in further detail.

[0033] The embodiment of the present application discloses a spliced ​​prefabricated wall.

[0034] Reference Figure 1 A spliced ​​prefabricated wall includes a cubic wall panel 1 and a plurality of steel bars 2 inserted in the wall panel 1, wherein the steel bars 2 include longitudinal steel bars 21 inserted vertically in the wall and transverse steel bars 22 inserted horizontally in the wall, both ends of the longitudinal steel bars 21 and the transverse steel bars 22 extend out of the wall panel 1 in the length direction, the transverse steel bars 22 and the transverse steel bars 22 of adjacent wall panels 1 in the horizontal direction are connected by welding, and the longitudinal steel bars 21 and the longitudinal steel bars 21 of adjacent wall panels 1 in the vertical direction are connected by welding, and the adjacent wall panels 1 are connected by the connection of the longitudinal steel bars 21 and the transverse steel bars 22, and a plurality of wall panels 1 are connected to form a spliced ​​prefabricated wall; a filling layer 3 is arranged between adjacent wall panels 1, and both ends of the filling layer 3 are respectively abutted against two adjacent wall panels 1, and the filling layer 3 is used to fill the gap between the adjacent wall panels 1 after the steel bars 2 are connected.

[0035] Reference Figure 1 , Figure 2 and Figure 3 A plurality of positioning rods 9 are installed on adjacent sides of the wall panel 1. A plurality of positioning holes 10 corresponding to the positioning rods 9 are opened on the two sides of the wall panel 1 opposite to the installation positioning rods 9. The positioning rods 9 are inserted into the positioning holes 10 to connect the adjacent wall panels 1 and align the steel bars 2 at the connection of the adjacent wall panels 1, thereby reducing the alignment time required for the subsequent connection of the steel bars 2; a plurality of through holes 11 corresponding to the positioning rods 9 are opened in the filling layer 3, and the positioning rods 9 pass through the through holes 11. The through holes 11 cover the positioning rods 9 and limit the filling layer 3 at the same time; Elastic layers 12 are connected to both ends of the filling layer 3, and the filling layer 3 is abutted against the wall panel 1 through the elastic layer 12. The elastic layer 12 is made of thermoplastic elastic material, which is a material with high elasticity, high strength and high resilience of rubber, and has the characteristics of environmental protection, non-toxicity and safety, a wide range of hardness, weather resistance, fatigue resistance and temperature resistance. When the adjacent wall panel 1 squeezes the elastic layer 12, the elastic layer 12 is deformed, making the fit between the elastic layer 12 and the wall panel 1 tighter, thereby improving the sealing between the elastic layer 12 and the wall panel 1.

[0036] Reference Figure 1 , Figure 2 and Figure 3 The filling layer 3 includes a fixing block 32 and a mounting block 31. The through hole 11 is provided on the fixing block 32. A plurality of mounting holes 4 corresponding to the number of the steel bars 2 extending out of the wall panel 1 are provided on the fixing block 32. The through hole 11 is provided on the fixing block 32 and passes through the fixing block. One end of the steel bar 2 extending out of the wall panel 1 is inserted into the mounting hole 4. The fixing block 32 has welding holes 5 corresponding to the mounting holes 4 at both ends along the width direction. The steel bars 2 inserted into the mounting holes 4 of the adjacent wall panels 1 are welded through the welding holes 5 to connect them. The welding connection of the adjacent steel bars 2 simultaneously makes The adjacent wall panels 1 are connected and fixed, and the mounting blocks 31 are installed at both ends of the welding holes 5 opened in the fixing blocks 32 and extend into the welding holes 5 to seal the welding holes 5, thereby reducing the poor air tightness of the connection of the wall panels 1 caused by the welding holes 5. At the same time, the mounting blocks 31 also seal the connection of the adjacent wall panels 1 after welding; a groove 6 is opened in the wall panel 1, and the mounting block 31 is countersunk and installed in the groove 6. The groove 6 provides positioning for the installation of the mounting block 31 and limits the installation position of the mounting block 31 so that the mounting block 31 is flush with the surface of the wall panel 1 after installation.

[0037] Reference Figure 2 and Figure 3 , an insulation layer 7 is installed on the inner wall of the mounting hole 4, and the insulation layer 7 is used to separate the heat during welding of the steel bar 2 from the filling layer 3, so as to reduce the damage of welding to the structure of the filling layer 3. The insulation layer 7 uses a high temperature resistant material, and the high temperature resistant material is made of quartz sand, clay, magnesite, dolomite and the like as raw materials. It is an inorganic coating with a temperature resistance range of -80 to 1800°C, which can inhibit the thermal radiation and heat conduction of high temperature objects and low temperature objects, and reduce the probability of the high temperature of the steel bar 2 during welding being transmitted to the filling layer 3 to damage the internal structure of the filling layer 3; a rubber pad 8 is connected to the side of the insulation layer 7 away from the steel bar 2, and the rubber pad 8 is made of ethylene-vinyl acetate copolymer, which is a general-purpose high molecular polymer with the characteristics of high resilience, high tensile strength and high toughness. When the steel bar 2 after welding is squeezed toward the rubber pad 8 due to deformation, the rubber pad 8 undergoes corresponding deformation so that the steel bar 2 after welding is still inserted in the mounting hole 4.

[0038] Reference Figure 1A functional layer 13 is connected to the wall panel 1 in the width direction. The functional layer 13 covers the wall formed by splicing the wall panels 1 to provide different performances for the wall. For example, when the wall installation environment is a noisy scene, the functional layer 13 uses sound insulation cotton, and the holes opened inside the sound insulation cotton reduce and absorb the sound waves, so that the sound waves passing through the wall are reduced; or when the wall installation environment requires thermal insulation, the functional layer 13 can use thermal insulation material rock wool board. The main raw material of the rock wool board is natural rock, which has strong high temperature resistance, low thermal conductivity, and good thermal insulation performance; at the same time, the functional layer 13 can also be superimposed and used according to different usage scenarios. For example, when noise reduction and heat preservation are required, the thermal insulation material and the sound insulation material can be used at the same time to make it have the function of thermal insulation and noise reduction, or a waterproof layer can be added to the surface on the basis of noise reduction.

[0039] The implementation principle of a spliced ​​prefabricated wall in an embodiment of the present application is as follows: after the wall panels 1 are cast, the wall panels 1 are spliced ​​to form a wall. During the splicing, the fixing block 32 is first installed on the wall panel 1 along the transverse direction of the wall panel 1, and then another wall panel 1 is hoisted and the positioning rod 9 is passed through the through hole 11 and into the positioning hole 10 to support the connection between the adjacent wall panels 1, and at the same time, the steel bars 2 extending out of the wall panel 1 are aligned and inserted into the installation hole 4, and then the steel bars 2 in the installation hole 4 are welded through the welding hole 5 to fix the steel bars 2 between the wall panels 1. After that, the installation block 31 is installed in the embedded groove 6 to seal the welding hole 5. At the same time, the installation of the installation block 31 allows the filling layer 3 to fill the gap between the adjacent wall panels 1 caused by welding. After the transverse connection is completed, the transverse connection is performed until the wall composed of several wall panels 1 meets the size requirements of the wall; the functional layer 13 is laid on the wall panel 1 according to the use requirements of the wall to give the wall different properties such as sound insulation and heat preservation; after the wall is spliced, it is transported to the construction site for installation.

[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
