Referring to fig. 1 to 5, the embodiment of the present application provides a prefabricated external wall panel 100 for forming an external wall of a building, which includes a substrate layer 110, a first construction sheet layer 120 and a second construction sheet layer 130, wherein the first construction sheet layer 120 is disposed between the substrate layer 110 and the second construction sheet layer 130, and wherein:

the substrate layer 110 is a supporting and fixing structure of the prefabricated external wall panel 100, and the substrate layer 110 is used for being embedded into a cavity formed by the beams 310 and the columns 320 of the frame structure 300 of the building so as to mount the prefabricated external wall panel 100 on the frame structure 300. The left and right sides of the substrate layer 110 have a first vertical end surface 111 and a fourth vertical end surface 112, respectively.

The first construction sheet layer 120 is attached to an outer side of the substrate layer 110 for covering a gap between the substrate layer 110 and the frame structure 300, and forms a first vertical groove 100f with the first construction sheet layer 120 of the horizontally adjacent prefabricated external wall panel 100. The first construction sheet layer 120 has second and fifth vertical end surfaces 121 and 122 on left and right sides thereof, respectively.

The second construction sheet layer 130 is attached to an outer side of the first construction sheet layer 120 to cover the first vertical groove 100f formed between the horizontally adjacent two prefabricated external panels 100, and to form a second vertical groove 100g with the second construction sheet layer 130 of the horizontally adjacent prefabricated external panel 100. The second construction sheet layer 130 has third and sixth vertical end surfaces 131 and 132 at left and right sides thereof, respectively.

The substrate layer 110, the first construction sheet layer 120 and the second construction sheet layer 130 are staggered in sequence in the horizontal direction, that is, the second vertical end surface 121 is located at the opposite inner side of the first vertical end surface 111, and the third vertical end surface 131 is located at the opposite inner side of the second vertical end surface 121. The first vertical end surface 111, the second vertical end surface 121 and the surface of the substrate layer 110 together form a first splice opening 100a; the second vertical end surface 121, the third vertical end surface 131, and the surface of the first construction sheet layer 120 collectively form a second splice opening 100b. The fifth vertical end surface 122 is located opposite the fourth vertical end surface 112, and the sixth vertical end surface 132 is located opposite the fifth vertical end surface 122. The portions of the first construction sheet layer 120 located at the fifth and fourth vertical end surfaces 122, 112 form a first flange 120a; the portions of the second construction sheet 130 located at the sixth and fifth vertical end surfaces 132 and 122 form a second flange 130a.

When the prefabricated external wall panel 100 provided by the embodiment of the application is used, the base plates of the plurality of prefabricated external wall panels 100 are respectively assembled and embedded into a plurality of cavities formed by the beams 310 and the columns 320 of the frame structure 300 of a building to be fixed. The first flange 120a and the second flange 130a of one prefabricated external wall panel 100 of two adjacent prefabricated external wall panels 100 arranged horizontally are inserted into the first splicing opening 100a and the second splicing opening 100b of the other prefabricated external wall panel 100, respectively. So that the column 320 placement groove 100e, the first vertical groove 100f and the second vertical groove 100g are respectively formed between the fourth vertical end surface 112, the fifth vertical end surface 122 and the sixth vertical end surface 132 of one prefabricated external wall panel 100 and the first vertical end surface 111, the second vertical end surface 121 and the third vertical end surface 131 of another prefabricated external wall panel 100.

The column 320 placing grooves 100e are used for accommodating the columns 320 of the frame structure 300, the first vertical grooves 100f serve as vertical protection cavities of the building outer wall, and the second vertical grooves 100g serve as vertical diversion trenches of the building outer wall. When the rainwater flows to the second vertical groove 100g on the surface of the outer wall, the rainwater can be collected into the second vertical groove 100g to form water flow, and the water flow flows downwards along the second vertical groove 100g and then is discharged out of the wall surface, so that the rainwater is prevented from permeating into the wall body through gaps among the prefabricated outer wall panels 100, the water seepage of the outer wall is prevented, and the water inflow of a building is avoided. If part of rainwater permeates into the wall body through gaps among the prefabricated external wall panels 100 due to overlarge external pressure and the like, when the part of rainwater permeates into the first vertical grooves 100f, the rainwater is discharged out of the wall body along the first vertical grooves 100f under the action of self weight due to pressure release, so that the rainwater is prevented from further permeating into the wall body.

And, the post 320 standing groove 100e is sheltered from by first structure sheet layer 120 and is covered, and first vertical groove 100f is sheltered from by second structure sheet layer 130 and is covered, is equivalent to that the gap between base plate layer 110 and frame construction 300 and the vertical gap between two adjacent prefabricated external wall panels 100 all are covered, makes the unable infiltration of rainwater to the wall in to can effectively prevent the outer wall infiltration, avoid the building to intake.

Furthermore, the gaps between the frame structure 300 and the prefabricated external wall panels 100 are covered by the prefabricated external wall panels 100, the gaps existing on the external wall are all lap joints between the adjacent prefabricated external wall panels 100, and the lap joints are used as the gaps on the external wall and are the only way for water seepage of the external wall, so that the way for water seepage of the external wall is reduced. For example, compared with the embedded wall panel, when the embedded wall panel is embedded in the frame structure, four gaps "up, down, left and right" are formed between each embedded wall panel and the frame structure, and the four gaps are the gaps of the outer wall, that is, the gaps are the water seepage paths of the outer wall. In the embodiment of the present application, the gap on the outer wall is an overlapping gap between the adjacent prefabricated outer wall panels 100, and a gap is formed between the adjacent prefabricated outer wall panels 100, so that the gap on the outer wall can be reduced, that is, the way of water seepage of the outer wall is reduced.

In addition, because the prefabricated external wall panel 100 provided by the embodiment of the application is embedded into the frame structure 300 for installation, the plurality of prefabricated external wall panels 100 of the formed external wall only have a position relationship but no connection relationship, that is, the plurality of prefabricated external wall panels 100 are mutually independent, so that the deformation of a single prefabricated external wall panel 100 does not affect the deformation of the whole external wall, and the prefabricated external wall panel 100 is directly embedded into the frame structure 300, so that the deformation between the prefabricated external wall panel 100 and the beams 310 and columns 320 of the frame structure 300 can be more coordinated, the accumulation of the deformation difference of the prefabricated external wall panel 100 can not be caused, and the overall integrity of the external wall is ensured.

First vertical groove 100f, second vertical groove 100g are formed by the concatenation of adjacent prefabricated exterior wall panel 100, and first vertical groove 100f, second vertical groove 100g can also provide the deformation space for between the adjacent prefabricated exterior wall panel 100, have avoided extruding each other between the adjacent prefabricated exterior wall panel 100 of level, play the effect of protection outer wall, have prolonged the life of outer wall.

Because the prefabricated external wall panels 100 are independent of each other, when a certain prefabricated external wall panel 100 is damaged and needs to be replaced or needs to be disassembled for other reasons, the prefabricated external wall panel 100 can be conveniently and independently assembled and disassembled without influencing the whole external wall.

It should be noted that, in the embodiment of the present application, the components of the prefabricated external wall panel 100 are the substrate layer 110, the first construction sheet layer 120 and the second construction sheet layer 130, only for the purpose of describing the functions and principles of the components of the prefabricated external wall panel 100 more concisely and clearly, and the prefabricated external wall panel 100 is not limited to be formed by splicing the independent substrate layer 110, the first construction sheet layer 120 and the second construction sheet layer 130. Correspondingly, the substrate layer 110, the first structural slab layer 120 and the second structural slab layer 130 of the prefabricated external wall panel 100 may be integrally processed from the same material, or may be respectively made from a plurality of different materials, and the specific material may be determined according to factors such as the use requirement of the building, so that the prefabricated external wall panel 100 is suitable for various building requirements.

The prefabricated external wall panels 100 provided by the embodiments of the present application are similar to the feathers of birds, and the prefabricated external wall panels 100 are stacked on each other to form the external wall of a building as if a piece of feathers are attached to the skins of the birds. Independent each other between each prefabricated external wall panel 100, each other does not influence, but can carry out the water conservancy diversion to the rainwater through the mode of overlapping each other again to prevent the outer wall infiltration. Moreover, the prefabricated external wall panels 100 are mutually overlapped to form the external wall of the building, the waterproof effect is realized by utilizing the shape and the structure of the prefabricated external wall panels 100 and the mutual cooperation between the adjacent prefabricated external wall panels 100, the physical waterproof principle is applied, compared with the external wall formed by embedded wall panels and the like, the gap on the external wall is filled and sealed by adopting the filling material, and the external wall formed by the prefabricated external wall panels 100 has the advantages of no external wall water seepage problem caused by the aging and cracking of the filling material, higher reliability and longer service life.
