[0025] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The prefabricated building insulation wall involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Example 1:

[0027] like Figure 1-9As shown, a prefabricated building insulation wall includes a sandwich insulation wall 1. Limiting grooves 2 are formed on both sides of the sandwich insulation wall 1. An I-shaped limiting rod 21 is provided inside the limiting groove 2. One side of the I-shaped limiting rod 21 is inserted into the limiting groove 2. A threaded block 23 is threadedly sleeved on the upper part of the limiting groove 2. The bottom of the threaded block 23 overlaps the middle of the top surface of the I-shaped limiting rod 21. Handles 22 are fixedly connected to both sides of the top surface of the I-shaped limiting rod 21. A groove is formed on the top of the threaded block 23, and a handle 231 is fixedly installed inside the groove. A positioning strip 3 is provided on the top of the sandwich insulation wall 1. The four corners of the positioning strip 3 are fixedly installed on the top of the sandwich insulation wall 1 by bolts. The two sides of the positioning strip 3... An installation port 31 is provided. A plug rod 33 is movably sleeved on one side of the installation port 31. One side of the plug rod 33 is arc-shaped. A return spring 32 is fixedly connected to the other side of the inner wall of the installation port 31. One end of the return spring 32 is fixedly connected to the other side of the plug rod 33. The bottom of the sandwich insulation wall 1 is provided with a positioning groove 4 that matches the outer wall of the positioning strip 3. Positioning openings 41 that match one side of the plug rod 33 are provided on both sides of the inner wall of the positioning groove 4. Two first installation holes 34 are symmetrically provided on the front of the positioning strip 3. Two second installation holes 42 are symmetrically provided on the bottom of the sandwich insulation wall 1. The second installation holes 42 are located below the first installation holes 34 and communicate with the interior of the positioning groove 4.

[0028] In this embodiment, the handle 22 facilitates the movement of the I-shaped limiting rod 21, allowing both sides of the I-shaped limiting rod 21 to be inserted into the limiting groove 2 between the two sandwich insulation wall bodies 1. This enables the two sandwich insulation wall bodies 1 to be horizontally assembled together. The handle 231 facilitates the screw connection of the threaded block 23 to the upper part of the limiting groove 2 between the two sandwich insulation wall bodies 1, thereby fixing the I-shaped limiting rod 21 between the two sandwich insulation wall bodies 1. This facilitates the horizontal fixed assembly of the two sandwich insulation wall bodies 1. The bottom positioning groove 4 fits onto the outer wall of the positioning strip 3 above another sandwich insulation wall 1, and the arc part on one side of the insertion rod 33 abuts against the inside of the positioning port 41, which facilitates the limiting of the two sandwich insulation wall 1. Then, bolts are used to fix the upper and lower sandwich insulation wall 1 together through the second mounting hole 42 and the first mounting hole 34, which facilitates the stability of the two sandwich insulation wall 1 when vertically splicing. If vertical assembly is not required, the bolts at the four corners of the positioning strip 3 can be removed, so that the positioning strip 3 can be removed from the top of the sandwich insulation wall 1.

[0029] Example 2:

[0030] like Figure 1-9As shown, the sandwich insulation wall 1 is composed of an inner wall 11, a sound-absorbing felt 12, a sound-absorbing panel 13, an insulation panel 14, and an outer wall 15. The insulation panel 14 is fixedly connected to the front of the outer wall 15, the sound-absorbing panel 13 is fixedly connected to the front of the insulation panel 14, the sound-absorbing felt 12 is fixedly connected to the front of the sound-absorbing panel 13, and the inner wall 11 is fixedly connected to the front of the sound-absorbing felt 12. The outer wall of the sound-absorbing panel 13 has multiple sound-absorbing holes 131, which are evenly distributed on the outer wall of the sound-absorbing panel 13.

[0031] In this embodiment, the insulation board 14 can be made of extruded polystyrene (XPS), which has good thermal insulation properties. Multiple sound-absorbing holes 131 on the sound-absorbing board 13 can absorb sound energy, reduce echoes and reverberation, thereby improving the indoor acoustic environment. Furthermore, the sound-absorbing felt 12 reduces sound propagation, thus improving the sound insulation of the wall.

[0032] In summary, as Figure 1-9 As shown, when using this type of prefabricated building insulation wall, during horizontal assembly, first align the two sandwich insulation wall 1 horizontally, then insert the I-shaped limiting rod 21 into the limiting groove 2 between the two sandwich insulation wall 1, and screw the threaded block 23 above the limiting groove 2 between the two sandwich insulation wall 1, and press the threaded block 23 down on the top surface of the I-shaped limiting rod 21, thereby fixing the I-shaped limiting rod 21 between the two sandwich insulation wall 1, which facilitates the horizontal fixed assembly between the two sandwich insulation wall 1. This method facilitates the rapid horizontal assembly between multiple sandwich insulation wall 1.

[0033] During vertical assembly, the positioning groove 4 at the bottom of one sandwich insulation wall 1 can be fitted onto the outer wall of the positioning strip 3 above another sandwich insulation wall 1. The inner wall of the positioning groove 4 is compressed by the insertion rod 33 and the return spring 32, causing the arc-shaped part on one side of the insertion rod 33 to retract into the installation port 31. When one side of the compressed insertion rod 33 is at the positioning port 41, the elasticity of the return spring 32 causes the arc-shaped part on one side of the compressed insertion rod 33 to abut against the inside of the positioning port 41, thereby limiting the position between the two sandwich insulation wall 1. When the two sandwich insulation wall 1 are vertically spliced ​​together, bolts can be used to connect the two installation holes 42 and 34, thereby fixing the upper and lower sandwich insulation wall 1 together and increasing the stability of the two sandwich insulation wall 1 when vertically spliced.

[0034] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may change.

[0035] Secondly: The accompanying drawings of the embodiments disclosed in this utility model only involve the structures involved in the embodiments disclosed in this utility model. Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.

[0036] In conclusion, the above are merely preferred embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
