[0002] The outer wall cladding is a construction method, which relates to fixing a plate on the surface of a building outer wall by a specific method (such as dry hanging), and aims to achieve decoration, heat preservation or other functional effects.

[0003] The existing Chinese utility model patent with the publication number CN219973662U discloses a low-carbon lightweight outer wall cladding, which comprises an inner layer and an outer layer. A heat preservation layer is arranged between the inner layer and the outer layer, and a galvanized light steel framework is arranged between the inner layer and the outer layer, and a reserved hole is arranged on the galvanized light steel framework. A low-carbon heat insulation pre-buried connecting piece is arranged in the inner part of the outer layer. The outer layer is made of high-performance concrete containing low-carbon cementitious material, and the thickness of the inner layer is 15-50 mm. The low-carbon lightweight outer wall cladding has the advantages of low cost, high strength and good durability, and can solve the problems of the strength, heat insulation and durability of the main connection mode of the outer wall, the looseness caused by the unreasonable fixing mode of the rock wool heat insulation board, the discontinuity of the heat insulation layer, the high price and the occupational health hazards.

[0004] However, in the above-mentioned low-carbon lightweight outer wall cladding, the outer layer and the galvanized light steel framework are connected through a plurality of low-carbon heat insulation pre-buried connecting pieces (which have been disclosed in the Chinese utility model patent with the publication number CN219386669U), that is, the connection is realized through the cooperation of bolts and nuts. The staff needs to tighten the nuts and bolts in the inner part of the galvanized light steel framework through the reserved hole, which has a large construction difficulty. In addition, due to the machining error between the outer layer and the galvanized light steel framework, after the outer layer and the galvanized light steel framework are connected through the plurality of low-carbon heat insulation pre-buried connecting pieces, the flatness of the surface of the outer wall cladding cannot be guaranteed, which affects the overall aesthetic degree of the final outer wall cladding.

[0049] The outer page layer 2 is in the form of a rectangular plate structure as a whole, one side of which in the thickness direction is used for connecting and fixing with the skeleton 4, and the side of the outer page layer 2 used for connecting and fixing with the skeleton 4 has a groove 21 matched with the skeleton 4; after the outer page layer 2 is connected and fixed with the skeleton 4, the groove wall of the groove 21 on the outer page layer 2 will abut against the two side surfaces of the skeleton 4 in the height direction and the side surface of the skeleton 4 away from the inner page layer 1 respectively, and the structures of the outer page layer 2 on both sides of the skeleton 4 in the height direction will abut against the surface of the inner page layer 1, so that the inner page layer 1, the outer page layer 2 and the skeleton 4 form a whole; and the length of the inner page layer 1, the length of the outer page layer 2 and the length of the skeleton 4 are all equal, so that the inner page layer 1, the outer page layer 2 and the skeleton 4 can jointly form an outer wall hanging plate with a flat surface. In the embodiment, the outer page layer 2 is preferably made of high-performance concrete containing low-carbon cementitious materials, which has the advantages of low cost, high strength and good durability.

[0051] Among the four embedded parts 5 near the same end of the outer page layer 2 in the length direction, two embedded parts 5 are located on both sides of the groove 21 in the width direction of the outer page layer 2, and the other two embedded parts 5 are located near the groove bottom of the groove 21 on the outer page layer 2, and the four embedded parts 5 are aligned and symmetrically distributed on the outer page layer 2 in the width direction of the outer page layer 2.

[0052] Referring to Figure 3 and Figure 4 , the embedded part 5 comprises a main body 53 and a cover body 54, and the embedded part 5 is preferably made of steel-fiber plastic composite material, and the main body 53 and the cover body 54 are preferably connected and fixed by welding (laser welding) to obtain the embedded part 5.

[0053] The main body 53 is in the form of a rectangular structure as a whole, and the inside of the main body 53 is provided with an installation slot 531 in the form of a rectangular structure as a whole, and the installation slot 531 penetrates through both sides of the main body 53 to form openings; the main body 53 has a blocking part 52 extending inward at one opening of the installation slot 531, and the blocking part 52 is distributed along the edge track of the opening, which can effectively block the objects of a certain size and shape in the installation slot 531 from leaving the installation slot 531 through the opening.

[0054] The cover body 54 is a rectangular plate structure as a whole, and one side of the cover body 54 in the thickness direction is provided with a clamping groove 541 matched with one end of the main body 53 away from the blocking part 52, so that the one end of the main body 53 away from the blocking part 52 is clamped and matched with the clamping groove 541 on the cover body 54, and then the cover body 54 and the main body 53 are connected and fixed by welding by the construction personnel.

[0055] After the cover body 54 is connected and fixed with the main body 53, the cover body 54 plugs the opening of the mounting groove 531 away from the blocking part 52, so that the mounting groove 531 forms the mounting space 51 inside the embedded part 5; at the same time, the two ends of the cover body 54 in the width direction extend outward relative to the main body 53 to form reinforcing flanges 542, which can effectively reinforce the position stability of the embedded part 5 after being embedded and installed on the outer leaf layer 2.

[0056] After the embedded part 5 is embedded and installed on the outer leaf layer 2, the end face of the main body 53 close to the blocking part 52 is flush with the groove wall corresponding to the groove 21.

[0057] The plurality of connecting assemblies 6 correspond to the plurality of embedded parts 5 one by one, so in this embodiment, it is preferred that the outer leaf layer 2 and the framework 4 are connected and fixed by cooperation of eight connecting assemblies 6 and eight embedded parts 5.

[0058] After the outer leaf layer 2 and the framework 4 are installed by cooperation of the groove 21, at this time the outer leaf layer 2 can slide and adjust relative to the framework 4 along the length direction of the outer leaf layer 2, so that the two ends of the outer leaf layer 2 in the length direction are flush with the end faces of the two ends of the inner leaf layer 1 in the length direction and the two ends of the framework 4 in the length direction.

[0059] Referring to Figure 4 and Figure 5 , the connecting assembly 6 includes a bolt 61, a nut 62 and a gasket 63.

[0060] Eight clearance openings 42 for the bolt 61 to pass through are correspondingly provided on the framework 4, the clearance openings 42 extend in the length direction of the framework 4 in a waist-shaped hole shape, and when the outer leaf layer 2 and the framework 4 are installed by cooperation of the groove 21, the eight clearance openings 42 can be communicated with the eight mounting spaces 51 of the embedded parts 5 respectively, and the length direction of the clearance opening 42 is parallel to the length direction of the corresponding mounting space 51.

[0063] The bolt 61 and the nut 62 are threadedly connected, and after the tail of the bolt 61 penetrates into the installation space 51 and aligns with the nut 62, the bolt 61 is controlled to rotate to achieve thread connection between the bolt 61 and the nut 62; during the thread connection between the bolt 61 and the nut 62, after the tail of the bolt 61 penetrates through the nut 62, subsequent control of the rotation of the bolt 61 can drive the nut 62 to move towards the blocking part 52 until the head of the bolt 61 tightly abuts against the skeleton 4 through the gasket 63 and the nut 62 tightly abuts against the blocking part 52, at which time the outer page layer 2 and the skeleton 4 are connected and fixed.

[0064] During the connection and fixation between the outer page layer 2 and the skeleton 4 through the cooperation of the connecting assembly 6 and the embedded part 5, the construction personnel can operate the connecting assembly 6 in the internal space of the skeleton 4 through the reserved opening 41, at which time the waist-shaped hole design of the accommodation opening 42 can facilitate the construction personnel to confirm the position of the nut 62 in the installation space 51, and at the same time, the construction personnel can conveniently penetrate the tail of the bolt 61 through the accommodation opening 42 into the installation space 51, thereby improving the efficiency of the connection and fixation between the outer page layer 2 and the skeleton 4.

[0065] Referring to Figure 3 and Figure 5 , further, in order to facilitate the construction personnel to quickly determine the position of the nut 62 in the installation space 51 during the thread connection between the bolt 61 and the nut 62 through the accommodation opening 42, the cover 54 is preferably provided with a limiting block 543 for limiting the position of the nut 62 in the installation groove 531.

[0066] The limiting block 543 is located on the side of the cover 54 close to the opening of the clamping groove 541, and has a ring-shaped structure and extends outward along the direction of the opening of the clamping groove 541; when the cover 54 is connected with the main body 53, the limiting block 543 will be located in the installation groove 531, and the outer surface of the limiting block 543 abuts against the circumferential groove wall of the installation groove 531.
