[0041] This application provides a prefabricated interior wall system that solves the technical problem in the prior art where tools used to assist in liquid nitrogen freezing damage cannot be positioned correctly when cooling in the container holding liquid nitrogen, thus failing to guarantee consistent cooling area each time and affecting the accuracy and repeatability of liquid nitrogen freezing damage operations.

[0042] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0043] like Figure 1 As shown, one or more embodiments of this application provide a prefabricated interior wall system, which includes multiple prefabricated wall panels 200 and a locator 100 for fixing the prefabricated wall panels 200 to the foundation wall 400 of the building.

[0044] like Figures 1-4 As shown, the locator 100 is approximately I-shaped, so as to... Figure 1 The positioner 100 shown is oriented in the usage state. It includes a first connector 120 for fixed connection with the foundation wall 400 of the building body on the rear side, and a second connector 110 for snap-fit ​​connection with the prefabricated wall panel 200 on the front side. The first connector 120 and the second connector 110 are connected as one unit through an intermediate connector 130, so that the prefabricated wall panel 200 can be positioned on the foundation wall 400.

[0045] like Figures 1-4 As shown, the first connector 120 is rectangular, and the intermediate connector 130 is also rectangular, with one long side of the intermediate connector 130 perpendicularly connected to the first connector 120. The inner surface of the first connector 120 facing the second connector 110 is recessed into the first connector 120 to form a first groove 121. The first groove 121 is used to install an adjusting screw. The adjusting screw connects the first groove 121 and the base wall 400, strengthening the connection between the locator 100 and the base wall 400. Furthermore, the adjusting screw can level the base wall 400; when the base wall 400 is uneven, it can be leveled by adjusting the screw's insertion depth to ensure the flatness of the prefabricated wall panel 200 and the flatness of its outer surface. This provides high installation flexibility and will not affect the construction progress or installation effect. In addition, the first groove 121 not only positions the installation location of the adjusting screw and guides its installation, but also increases the distance between the first connector 120 and the second connector 110, increasing the installation space and facilitating the installation of the adjusting screw.

[0046] Further, the first recess 121 is only arranged on the side of the first connecting piece 120 located on one side of the intermediate connecting piece 130, generally the right side, so that when the assembled wall panel 200 is paved from left to right on the foundation wall 400, it can be ensured that the first recess 121 on the right side is not blocked by the intermediate connecting piece 130 and is exposed, thereby facilitating the assembly of the leveling screw and reducing the construction difficulty.

[0047] Further, the outer surface part of the first connecting piece 120 facing the foundation wall 400 is recessed inward to form a second recess 122, so that the slot 123 of the second recess 122 is linear, forming a linear force point. If the foundation wall 400 is not flat, the first connecting piece 120 can be more easily abutted on the foundation wall 400 when it is screwed on the foundation wall 400 by the leveling screw, thereby improving stability and reducing installation difficulty.

[0048] Further, the first recess 121 and the second recess 122 are arranged on the first connecting piece 120 in a staggered manner along the width direction of the first connecting piece 120, so that the first connecting piece 120 can uniformly force on the foundation wall 400, thereby improving overall stability.

[0049] As shown in Figures 1-4 , the second connecting piece 110 is rectangular, and the second connecting piece 110 is arranged in parallel with the first connecting piece 120, and the other long side of the intermediate connecting piece 130 is connected perpendicularly to the middle position of the second connecting piece 110 in the width direction. Thus, after the positioner 100 is fixed on the foundation wall 400, the clamping grooves 342 (see the description below) on the two assembled wall panels 200 can be symmetrically clamped into the two ends of the second connecting piece 110 in the width direction, thereby connecting the two adjacent assembled wall panels 200 into one and positioning them on the foundation wall 400. The two ends of one second connecting piece 110 can respectively fix one assembled wall panel 200, so that one positioner 100 can fix two assembled wall panels 200, thereby effectively improving the installation efficiency and reducing the use of installation parts.

[0050] Further, the width of the first connecting piece 120 is greater than the width of the second connecting piece 110, so as to increase the connection area of the first connecting piece 120 and the foundation wall 400.

[0051] In addition, the height of the positioner 100 can be less than the height of the assembled wall panel 200, and multiple positioners 100 can be arranged in the height direction of the assembled wall panel 200 to meet the positioning strength requirement, as shown in Figure 5 .

[0052] Of course, the first connector 120, the second connector 110, and the third connector 120 can also be other shapes, such as triangles, hexagons, etc., which are not limited here.

[0053] As can be seen, by using the locator 100 to install the prefabricated wall panel 200 onto the foundation wall 400, the locator 100 can not only position the prefabricated wall panel 200 on the foundation wall 400 without damaging the outer surface of the prefabricated wall panel 200 or affecting its appearance; at the same time, the locator 100 can also play a leveling role. If the foundation wall 400 is uneven, it can be flexibly leveled. On the one hand, this enhances the stability and flatness of the prefabricated wall panel 200 installed on the foundation wall 400, and on the other hand, it improves the flexibility of construction, reduces the difficulty of construction, and lowers the technical requirements for construction workers.

[0054] by Figure 1 The orientation of the prefabricated wall panel 200 in its usage state is shown. The prefabricated wall panel 200 includes a wall panel body 210 and a decorative panel 220 disposed on the outer front surface of the wall panel body 210. The decorative panel 220 serves a decorative function, and can be wall decoration materials such as ceramic tiles or wood veneer. The wall panel body 210 can be a hollow wall panel, serving to support the decorative panel 220, and also providing sound insulation, heat insulation, and waterproofing functions. For example, it can be a polyurethane lightweight wall panel or calcium silicate board. The decorative panel 220 can be bonded to the wall panel body 210 using polyurethane adhesive. Polyurethane adhesive has excellent rubber properties and can adapt to the bonding of substrates with different coefficients of thermal expansion. It forms a soft-hard transition layer between the substrates, which not only has strong adhesion but also excellent buffering and shock absorption functions, thereby making the decorative panel 220 firmly connected to the wall panel body 210. Of course, other fixing methods can also be used, and there are no limitations here.

[0055] At least one end of the wall panel body 210 along its width direction is provided with a groove, and a wall panel profile 300 is fixedly embedded in the groove. The wall panel profile 300 can be used to connect the locator 100 to realize the connection of two adjacent prefabricated wall panels 200 on the base wall 400. For example, in one embodiment of this application, the wall panel body 210 is provided with the wall panel profile 300 at both ends along its width direction.

[0056] like Figures 6-9As shown, in one embodiment of this application, the wall panel profile 300 includes a first side 310, a second side 320, and a third side 330 respectively for abutting against the two groove walls and the bottom of the groove, and also includes a fourth side 340 located at the groove opening. The first side 310, the second side 320, the third side 330, and the fourth side 340 are interconnected and enclose a hollow column. Specifically, the first side 310, the second side 320, and the third side 330 can be bonded and fixed to the two groove walls and the bottom of the groove; or, as... Figure 9 As shown, the wall panel body 210 includes two front and rear panels 211 and 212, and a grout layer 213 poured between the two panels 211 and 212. Grout is poured between the front and rear panels 211 and 212 and the wall panel profiles 300 on both sides. After the grout cures, the wall panel profiles 300 and the wall panel body 210 are connected as one unit. For example, the grout can be wall panel materials such as magnesium oxysulfate cement.

[0057] like Figures 1-9 As shown, the fourth side surface 340 includes a positioning edge 341 that is flush with the groove and adjacent to the rear surface of the wall panel body 210, and a slot 342 that is recessed into the hollow column and connected to the positioning edge 341. The fourth side surface 340 also includes a guide edge 343 that extends along the width direction of the decorative panel 220 and partially covers the width direction of the decorative panel 220 (i.e., the length of the guide edge 343 is shorter than the thickness of the decorative panel 220). The guide edge 343 is used to guide the assembly of two adjacent prefabricated wall panels 200. Specifically, the fourth side surface 340 also includes a connecting edge 345. One side of the slot 342 is connected to the guide edge 343 through the connecting edge 345, and the other side of the slot is connected to one end of the positioning edge 341.

[0058] like Figure 1As shown, two adjacent said assembled wallboards 200 can be fixedly connected as a whole by the positioner 100 and positioned on the base wall 400 of the building. During installation, first, the first connecting piece 120 of the positioner 100 is fixed on the base wall 400, and then the clamping grooves 342 of two said assembled wallboards 200 are respectively clamped into the two ends of the second connecting piece 110 of the positioner 100, so that the installation is simple and fast. By aligning and abutting the guide edges 343 of the wallboard profiles 300 on the two adjacent said assembled wallboards 200, the two adjacent said assembled wallboards 200 can be guided to be installed in place on the positioner 100, and the installation workers do not need to have too much installation experience. In addition, the thickness of the guide edge 343 is half of the thickness of the middle connecting piece 130, so that when the guide edges 343 of the two adjacent said assembled wallboards 200 are aligned and abutted, the gap width b formed is the same as the middle connecting piece 130, so as to ensure that when the clamping grooves 342 are symmetrically clamped into the second connecting piece 110 in place, the two positioning edges 341 abut against the two sides of the middle connecting piece 130, so that the installation alignment is very convenient and accurate, and the overall connection stability is higher. In addition, the guide edge 343 can also make the mutual positioning stability between the two assembled wallboards 200 better, the connection more firm, and the sealing more strong. At the same time, the guide edge 343 can make the same standard installation joint a (i.e. the thickness of the two guide edges 343) between the two adjacent facing plates 220, so that the wall surface formed by the assembled wallboards 200 is beautiful, uniform and unified, the standardization and process of installation are realized, and the installation efficiency, installation quality and stability can be effectively improved.

[0059] As shown in Figure 10 , 11 , some wallboard profiles 300 can also be provided with a positioning groove 347 on the fourth side 340 thereof, the positioning groove 347 is arranged side by side with the clamping groove 342 of the wallboard profile 300, the slot of the positioning groove 347 is flush with the guide edge 343, and the positioning groove 347 is located between the clamping groove 342 and the guide edge 343, i.e. the positioning groove 347 is located on the side close to the facing plate 220, to form a female wallboard profile 300. Specifically, the positioning groove 347 can be arranged on the connecting edge 345.

[0060] Alternatively, as shown in Figure 12 , the fourth side 340 of another said wallboard profile 300 can also be provided with a clamping head 346, the clamping head 346 is arranged side by side with the clamping groove 342 of the wallboard profile 300, and the clamping head 346 protrudes from the guide edge 343, so as to form a male wallboard profile 300, and the clamping head 346 of the male wallboard profile 300 can be inserted into the positioning groove 347 of the female wallboard profile 300. Specifically, the clamping head 346 can be arranged on the connecting edge 345.

[0061] When the adjacent fabricated wallboard 200 with female wallboard profile 300 and fabricated wallboard 200 with male wallboard profile 300 are installed on the base wall 400 through the positioner 100, as shown, the female wallboard profile 300 is oppositely buckled with the male wallboard profile 300, and the clamping head 346 of the male wallboard profile 300 is just inserted into the positioning slot 347 of the female wallboard profile 300, which not only can guide the installation between the adjacent fabricated wallboard 200, but also can further strengthen the connection strength between them; at the same time, the cooperation of the clamping head 346 and the clamping slot 342 can play a waterproof partition role, avoiding water penetrating inward between the adjacent two wallboard profiles 300 to the base wall 400, or vice versa. Figure 13

[0062] Further, the positioning slot 347 is also provided with a sealing pad (such as a rubber pad) to eliminate the gap between the clamping head 346 and the positioning slot 347, so as to further improve the waterproof performance.

[0063] An exemplary use method of the fabricated wallboard 200 provided by the embodiment of the application installed on the base wall 400 is as follows:

[0064] The first connecting piece 120 is fixed on the base wall 400 through the leveling screw, and the first connecting piece 120 is leveled; the clamping slots 342 on the two base walls 400 are symmetrically clamped into the two ends of the second connecting piece 110 in the width direction, so as to connect the adjacent two fabricated wallboards 200 into one and position them on the base wall 400.

[0065] It should be understood that although the terms of quantity such as "first", "second" and the like can be used herein to describe various units, these units should not be limited by these terms. These terms are only used to distinguish one unit from another unit. For example, without departing from the scope of the exemplary embodiments, the first unit can be called the second unit, and similarly the second unit can be called the first unit.
