Description

Technical Field

[0001] This application relates to the field of thermal insulation wall technology, and more specifically, to a prefabricated green energy-saving decorative wall insulation system and construction method. Background Technology

[0002] With increasingly stringent requirements for building energy conservation, thermal insulation wall systems have become an indispensable component of modern buildings. Traditional thermal insulation wall systems often employ external insulation boards or external insulation mortar, which have limitations in terms of construction efficiency, quality control, and long-term durability. In recent years, prefabricated, integrated interior thermal insulation wall panels have gradually gained market attention. These panels, manufactured in factories and assembled on-site, aim to improve construction efficiency and consistency in decorative effects.

[0003] Existing integrated, monolithic insulation wall panels typically consist of an insulation core and interior / exterior decorative layers, manufactured in a factory to form a large, panel-like component. These are then transported to the site and installed directly onto the interior wall substrate using bonding and anchoring methods. However, this type of integrated, monolithic insulation wall panel is prone to deformation, cracking, and even detachment due to factors such as thermal expansion and contraction. These defects not only affect the building's thermal insulation performance but may also pose safety hazards. Maintenance requires repairing or replacing the entire insulation panel, resulting in cumbersome and costly maintenance procedures. Summary of the Invention

[0004] In view of this, this application provides a prefabricated green energy-saving decorative wall insulation system to solve the technical problems of easy cracking and cumbersome maintenance of the single insulation wall panel used in the existing insulation wall system.

[0005] This application provides a prefabricated green and energy-saving decorative wall insulation system, wherein the prefabricated green and energy-saving decorative wall insulation system includes: Ceiling joists are installed on the top of the interior wall surface and have a first hanging rail beam that extends along the length of the ceiling joists. Multiple thermal insulation wall panel modules are arranged sequentially at intervals along the length of the ceiling keel. Each thermal insulation wall panel module includes multiple thermal insulation wall panel units connected sequentially from top to bottom. Each thermal insulation wall panel unit is attached to the wall surface of the interior wall. The uppermost thermal insulation wall panel unit in each thermal insulation wall panel module is suspended on the first hanging rail beam. Multiple flexible insulation strips are provided between adjacent insulation wall panel modules, and the upper end of the flexible insulation strips is suspended from the first hanging rail beam.

[0006] Furthermore, the outermost insulation wall panel module among the multiple insulation wall panel modules is provided with the flexible insulation strip on its outer side.

[0007] Furthermore, the thermal insulation wall panel unit includes a fixing frame and a thermal insulation wall panel. The fixing frame has limiting edges on both sides in the thickness direction that extend toward the inside of the fixing frame. The thermal insulation wall panel is embedded in the inner side of the corresponding fixing frame and is limited by the limiting edges.

[0008] Furthermore, the fixing frame includes an upper frame beam, a lower frame beam, and two side frame beams. The lower frame beam is located below the upper frame beam, and the two ends of the upper frame beam and the lower frame beam are connected through the two side frame beams. The lower frame beam has a vertical through hole, and the limiting edge corresponding to the lower frame beam forms a limiting groove above the lower frame beam. A rectangular nut is provided in the limiting groove. The lower end of the insulation wall panel forms a relief cavity to accommodate the rectangular nut. The rectangular nut is limited along the thickness direction of the fixing frame by the limiting edge corresponding to the lower frame beam. The upper end of the upper frame beam of the insulation wall panel unit below the uppermost insulation wall panel unit in each insulation wall panel module is provided with a screw rod. Each screw rod passes through the vertical through hole of the lower frame beam of the fixing frame above the screw rod and is threadedly connected to the rectangular nut on the lower frame beam of the fixing frame above the screw rod.

[0009] Furthermore, the vertical perforation is an elongated hole, the length direction of which is consistent with the length direction of the ceiling joist, the length direction of the clearance cavity is consistent with the length direction of the ceiling joist, and the rectangular nut can slide along the length direction of the clearance cavity within the clearance cavity.

[0010] Furthermore, a flexible insulation layer is provided on the outer side of the fixed frame.

[0011] Furthermore, the lower surface of the first hanging rail beam is formed with a first hanging groove extending along the length direction of the ceiling keel, and the upper end of the flexible insulation strip has a first hanging head. The first hanging head can be slidably limited in the first hanging groove along the length direction of the ceiling keel. The upper end of the uppermost insulation wall panel unit in each insulation wall panel module is provided with a second hanging head. The second hanging head can be slidably limited in the first hanging groove along the length direction of the ceiling keel.

[0012] Furthermore, the ceiling keel has a second hanging rail beam, which is parallel to the first hanging rail beam. The prefabricated green energy-saving decorative wall insulation system includes multiple decorative wall panels suspended below the second hanging rail beam. The insulation wall panel module and the flexible insulation strip are located between the wall surface of the interior wall and the decorative wall panel. The lower surface of the second hanging rail beam forms a second hanging groove extending along the length direction of the ceiling keel. The upper end of the decorative wall panel has a third hanging head, which can be slidably limited in the second hanging groove along the length direction of the ceiling keel.

[0013] Furthermore, the ceiling keel has a connecting beam and a supporting beam. The connecting beam is located above and parallel to the first hanging rail beam. The connecting beam is connected to the interior wall by threaded fasteners. Both the connecting beam and the supporting beam are parallel to the first hanging rail beam. The two ends of the connecting beam, the supporting beam, the first hanging rail beam, and the second hanging rail beam are connected by end frames. The two ends of the connecting beam and the supporting beam each have a connecting channel. The connecting channel extends along the length of the ceiling keel. The prefabricated green energy-saving decorative wall insulation system includes a first connecting rod and a second connecting rod. The first connecting rod can be inserted into the connecting channel of the connecting beam of two adjacent ceiling keels, and the second connecting rod can be inserted into the connecting channel of the supporting beam of two adjacent ceiling keels.

[0014] Furthermore, the present invention also provides a construction method for a prefabricated green energy-saving decorative wall insulation system, wherein the construction method is implemented based on the above-mentioned prefabricated green energy-saving decorative wall insulation system, and the construction method includes the following steps: a. Connect the connecting beam of the ceiling joists to the interior wall using threaded fasteners; b. Assemble multiple insulation wall panel modules, ensuring that the number of insulation wall panel units in each module is the same. The number of insulation wall panel units in each module is determined based on the height of the first hanging rail beam of the ceiling keel to the indoor floor. When assembling each insulation wall panel module, the upper end of the uppermost insulation wall panel unit below the uppermost insulation wall panel unit in each module is threaded through the vertical through hole of the lower frame beam of the fixed frame above the threaded rod and connected to the rectangular nut on the lower frame beam of the fixed frame above the threaded rod. c. By sliding the first hoisting head laterally into the first hoisting slot and the second hoisting head laterally into the first hoisting slot, multiple thermal insulation wall panel modules and multiple flexible thermal insulation strips are alternately hoisted on the ceiling keel, so that there are flexible thermal insulation strips between adjacent thermal insulation wall panel modules, and the outermost thermal insulation wall panel module among the multiple thermal insulation wall panel modules has the flexible thermal insulation strip on its outer side. d. The third lifting head slides laterally into the second lifting slot to suspend multiple decorative wall panels on the ceiling keel.

[0015] The beneficial effects of the prefabricated green energy-saving decorative wall insulation system provided by this invention are as follows: Compared to existing technologies, the prefabricated green energy-saving decorative wall insulation system provided by this invention features multiple insulation wall panel modules suspended on the first hanging rail beam of the ceiling keel, and multiple flexible insulation strips suspended on the first hanging rail beam of the ceiling keel. Each insulation wall panel module includes multiple insulation wall panel units connected sequentially from top to bottom, with the flexible insulation strips positioned between adjacent insulation wall panel modules. When the insulation wall panel units expand and contract with temperature, the vertically adjacent insulation wall panel units can have room for movement, and the horizontally adjacent insulation wall panel modules can squeeze the flexible insulation strips to move. This effectively divides the entire insulation wall into multiple independent modules, creating a space for the insulation wall panel units to expand and contract with temperature. This prevents problems such as deformation, cracking, or even detachment of the entire insulation wall due to thermal expansion and contraction. When a certain insulation wall panel unit is damaged, only that insulation wall panel unit needs to be repaired or replaced, making maintenance convenient and cost-effective.

Each insulation wall panel module includes multiple insulation wall panel units 200 connected sequentially from top to bottom. Flexible insulation strips 2 are provided between adjacent insulation wall panel modules. When the insulation wall panel units 200 expand and contract thermally, the adjacent insulation wall panel units 200 are connected. The insulation wall panel 200 has a margin of safety, allowing horizontally adjacent insulation wall panel modules to move by compressing the flexible insulation strip 2. This effectively divides the entire insulation wall into multiple independent modules, creating a space for thermal expansion and contraction between these modules. This prevents deformation, cracking, or even detachment of the entire insulation wall due to thermal expansion and contraction. When a particular insulation wall panel 200 is damaged, only that insulation wall panel 200 needs to be repaired or replaced, making maintenance convenient and cost-effective.

[0026] According to one embodiment of this application, a flexible insulation strip 2 is provided on the outermost side of the outermost insulation wall panel module among a plurality of insulation wall panel modules.

[0031] According to one embodiment of this application, a flexible insulation layer (not shown) is provided on the outer side of the fixed frame 201. The flexible insulation layer may be insulation cotton or the like. The gap between adjacent fixed frames 201 is filled by the flexible insulation layer on the outer side of the fixed frame 201 to ensure that the insulation wall panel module forms good insulation performance.

[0032] According to one embodiment of this application, a first hanging rail beam 101 has a first hanging groove 102 extending along the length direction of the ceiling joist 100 on its lower surface.

The upper end of the decorative wall panel 7 has a third hanging head 8, which can be slidably limited in the second hanging groove 104 along the length direction of the ceiling joist 100.

[0034] See Figure 1 , Figure 2 and Figure 11 According to one embodiment of this application, the ceiling joist 100 has a connecting beam 105 and a supporting beam 106. The connecting beam 105 is located above and parallel to the first hanging rail beam 101. The connecting beam 105 is connected to the interior wall 1 by threaded fasteners. Specifically, a connecting hole 110 is formed on the connecting beam 105. The threaded fasteners are expansion bolts, expansion screws, etc., that pass through the connecting hole 110 and extend into the interior wall 1. Both the connecting beam 105 and the supporting beam 106 are parallel to the first hanging rail beam 101. The two ends of each of the connecting beam 105, the supporting beam 106, the first hanging rail beam 101, and the second hanging rail beam 103 are connected by an end frame 107.

The two adjacent ceiling joists 100 are then fixed by bolts passing through the mounting holes 109 and into the corresponding threaded holes 10. The advantage of this embodiment is that the length of the ceiling joists 100 can be extended according to the length of the wall.

[0035] Furthermore, this invention also provides a construction method for a prefabricated green energy-saving decorative wall insulation system, wherein the construction method is implemented based on the aforementioned prefabricated green energy-saving decorative wall insulation system, and the construction method includes the following steps: a. Connect the connecting beam 105 of the ceiling joist 100 to the interior wall 1 using threaded fasteners; b. Assemble multiple insulation wall panel modules so that the number of insulation wall panel units 200 in each insulation wall panel module is the same. The number of insulation wall panel units 200 in each insulation wall panel module is determined according to the height of the first hanging rail beam 101 of the ceiling keel 100 and the indoor ground. When assembling each insulation wall panel module, the screw 4 at the upper end of the upper frame beam 204 of the insulation wall panel unit 200 below the uppermost insulation wall panel unit 200 in each insulation wall panel module passes through the vertical through hole 207 of the lower frame beam 205 of the fixing frame 201 above the screw 4 and is threaded to the rectangular nut 3 on the lower frame beam 205 of the fixing frame 201 above the screw 4. c.
