[0002] Prefabricated exterior wall panels, also known as prefabricated concrete exterior wall panels or prefabricated wall units, are a type of building component commonly used in building industrialization and prefabricated buildings. They are prefabricated in factories and then transported to construction sites for installation. With the development of building industrialization, prefabricated exterior wall panels are increasingly used in residential, commercial and industrial buildings. During installation, prefabricated exterior wall panels are mainly installed between two adjacent floors.

[0019] like Figure 1-4 As shown, a connection structure of a prefabricated exterior wall panel 1 and a floor structure in a preferred embodiment of the utility model, the prefabricated exterior wall panel 1 is arranged between two adjacent floor structures, the floor structure includes a structural beam 2 and a floating plate 3 arranged on one side of the structural beam 2 in a lateral direction, the floating plate 3 is provided with an anti-ridge 4, the prefabricated exterior wall panel 1 is vertically installed on the anti-ridge 4 of the lower layer, the top of the prefabricated exterior wall panel 1 is fixedly connected to the bottom of the floating plate 3 of the upper layer, the cross-section of the prefabricated exterior wall panel 1 is rectangular, the angle between the lateral side of the prefabricated exterior wall panel 1 and the lateral side of the structural beam 2 is an acute angle, and the prefabricated exterior wall panel 1 is close to the anti-ridge 4 of the lower layer. The lateral side of the structural beam 2 of the upper layer is the first lateral side, and the longitudinal side of the prefabricated exterior wall panel 1 close to the structural beam 2 of the upper layer is the first longitudinal side. Concrete is poured between the top of the first lateral side and the structural beam 2 of the upper layer (the lateral side close to the floating plate 3) and between the top of the first longitudinal side and the structural beam 2 of the upper layer, respectively, to form a first fixed block 21 fixedly connected to the top of the prefabricated exterior wall panel 1. Generally, the top of the first fixed block 21 is fixedly connected to the bottom of the floating plate 3 of the upper layer, and the bottom surface of the first fixed block 21 is flush with the bottom surface of the structural beam 2 of the upper layer.

[0020] The working principle of this embodiment is as follows: the top of the prefabricated exterior wall panel 1 is fixedly connected to the bottom of the upper floating board 3, and the bottom end of the prefabricated exterior wall panel 1 is installed on the anti-ridge 4, thereby realizing the installation and fixation of the prefabricated exterior wall; since the angle between the lateral side of the prefabricated exterior wall panel 1 and the lateral side of the structural beam 2 is an acute angle, and the cross-section of the prefabricated exterior wall panel 1 is rectangular, there is space for pouring concrete between the first lateral side and the first longitudinal side of the prefabricated exterior wall panel 1 and the side of the structural beam 2 close to the floating board 3, so concrete is poured here to form a first fixed block 21, which is simple to construct, and the structural beam 2 is connected to the prefabricated exterior wall panel 1 through the first fixed block 21, ensuring that the installation structure of the prefabricated exterior wall panel 1 is stable.

[0021] Exemplarily, the floating plate 3 includes a first floating plate 31 and a second floating plate 32, the second floating plate 32 is located below the first floating plate 31, and concrete is poured between the first floating plate 31 and the second floating plate 32 to form a second fixed block 33, and the position of the second fixed block 33 corresponds to the position of the prefabricated exterior wall panel 1; the prefabricated exterior wall panel 1 is provided with a vertical steel bar 11, and the top end of the vertical steel bar 11 extends out of the top end of the prefabricated exterior wall panel 1 and passes through the second floating plate 32 of the upper layer and is inserted into the second fixed block 33, ensuring that the top end of the prefabricated exterior wall panel 1 is connected and fastened to the bottom end of the floating plate 3 of the upper layer.

[0022] Exemplarily, a mounting hole 12 (reserved during production) is provided at the bottom of the prefabricated exterior wall panel 1, and a fixed steel bar 5 is inserted and fixed in the mounting hole 12. The fixed steel bar 5 passes through the first floating plate 31 and the second fixed block 33 of the lower layer in sequence and is inserted into the second floating plate 32, so as to facilitate the installation and fixation of the prefabricated exterior wall panel 1.

[0023] Exemplarily, slurry is poured between the inner wall of the mounting hole 12 and the outer side of the fixed steel bar 5. Specifically, the aperture of the mounting hole 12 is larger than the diameter of the fixed steel bar 5. The side of the prefabricated exterior wall panel 1 is provided with a grouting port and a grouting outlet connected to the mounting hole 12. Under the premise of ensuring the sealing between the bottom end of the prefabricated exterior wall panel 1 and the counter-ridge 4, slurry is poured into the mounting hole 12 through the grouting port so that the slurry fills the mounting hole 12, ensuring that the fixed steel bar 5 is firmly inserted and fixed in the mounting hole 12, thereby ensuring that the prefabricated exterior wall panel 1 is firmly installed on the counter-ridge 4. In this embodiment, C40 grade high-strength grouting material is used.

[0024] Exemplarily, the fixed steel bar 5 includes a vertical section 51 and a horizontal section 52, and the vertical section 51 and the horizontal section 52 have a smooth transition. The top end of the vertical section 51 is inserted and fixed in the mounting hole 12. The vertical section 51 passes through the first floating plate 31 and the second fixed block 33, and the horizontal section 52 is arranged in the second floating plate 32, so that the fixed steel bar 5 is fastened to the floating plate 3.

[0025] Exemplarily, a wooden box 34 is filled between the first floating board 31 and the second floating board 32, that is, in the space between the first floating board 31 and the second floating board 32, except for the space where the second fixed block 33 is located, the rest of the space is filled with wooden boxes 34. The wooden boxes 34 are used as filling materials. Compared with materials such as concrete, they are lighter, which can reduce the dead weight of the entire structure, reduce the pressure on the foundation, and can provide certain heat insulation and sound insulation effects.

[0026] Exemplarily, the present structure also includes a diagonal brace 6, and the floor structure also includes a floor slab 7 arranged on the side of the structural beam 2 away from the floating plate 3. One end of the diagonal brace 6 is connected to the first lateral side, and the other end of the diagonal brace 6 is connected to the floor of the lower layer. The arrangement of the diagonal brace 6 can provide additional supporting force to prevent the prefabricated exterior wall panel 1 from being displaced or overturned under wind load, earthquake or other external forces, thereby enhancing the stability of the structure.

[0027] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
