DETAILED DESCRIPTION

[0026] The present invention will be further described below in conjunction with the accompanying drawings.

[0027] Embodiment 1 An assembled exterior wall comprises a steel structure main body 1 and an exterior wall panel 2. To facilitate fixing the exterior wall panel 2 on the steel structure main body 1, a steel structure connector is fixed on the steel structure main body 1. A slot is formed on the wall panel connector. A wall panel connector is fixedly connected to the exterior wall panel 2. The steel structure connector is adapted to the slot, that is, the steel structure connector is inserted into the slot, thereby realizing connection between the steel structure connector and the wall panel connector. The steel structure main body 1 and the exterior wall panel 2 are connected by mutually inserting the steel structure connector and the wall panel connector, so as to improve the installation efficiency of the exterior wall panel 2.

[0028] In this embodiment, the steel structure connector includes a bottom connection seat 8 and a top connection seat 9 respectively fixed on the steel structure body 1, wherein the bottom connection seat 8 is connected to the bottom of the frame of the steel structure body 1, and the top connection seat 9 is connected to the top of the frame of the steel structure body 1. The structure of the bottom connection seat 8 is consistent with that of the top connection seat 9, and both include a horizontal plate 8-1 and a vertical plate 8-2 arranged in an L shape, and a second adjustment groove 8-3 is provided on the horizontal plate 8-1. The horizontal plate 8-1 is installed on the steel structure body 1 through the second adjustment groove 8-3, and the length direction of the second adjustment groove 8-3 is arranged perpendicular to the exterior wall plate 2, so as to adjust the gap between the exterior wall plate 2 and the steel structure body 1. During installation, the bottom connection seat 8 and the top connection seat 9 are arranged opposite to each other, that is, the vertical plate 8-2 of the bottom connection seat 8 and the vertical plate 8-2 of the top connection seat 9 are respectively arranged toward the center position of the steel structure body 1.

[0029] The wall panel connector includes a first fixing member 6 and a second fixing member 7. The first fixing member 6 is fixed to the bottom of the exterior wall panel 2, and the second fixing member 7 is fixed to the top of the exterior wall panel 2. A first plug-in slot 6-1 adapted to the steel structure connector is provided in the first fixing member 6. The bottom connecting seat 8 is plugged into the first plug-in slot 6-1. The second fixing member 7 is assembled with the exterior wall panel 2 to form a second plug-in slot 7-1. The top connecting seat 9 is plugged into the second plug-in slot 7-1. The opening direction of the first plug-in slot 6-1 is opposite to the opening direction of the second plug-in slot 7-1, so that the first plug-in slot 6-1 and the second plug-in slot 7-1 can be used to limit the vertical direction of the exterior wall panel 2, thereby preventing the exterior wall panel 2 from moving vertically. The first plug-in slot 6-1 and the second plug-in slot 7-1 are combined to form a slot of the wall panel connector, which is used to install and fix the exterior wall panel 2.

[0030] The first fixing member 6 is L-shaped, and the first fixing member 6 includes a base 6-2 and a groove plate 6-3. The base 6-2 is fixed on the exterior wall panel 2, and one side edge of the groove plate 6-3 is fixedly connected to the base 6-2. Preferably, the groove plate 6-3 is formed by bending part of the plate inside the base 6-2, so that a first plug-in slot 6-1 with three-sided openings is formed between the base 6-2 and the groove plate 6-3. Since the first plug-in slot 6-1 is a groove-type structure with three-sided openings, the bottom connecting seat 8 can be horizontally moved in the first slot 6-1, thereby facilitating the lateral adjustment of the exterior wall panel 2 so that adjacent exterior wall panels 2 can abut against each other.

[0031] A first adjustment groove 6-4 is provided on the base 6-2, and the length direction of the first adjustment groove 6-4 is set in the vertical direction. The base 6-2 is fixed on the outer wall panel 2 through the first adjustment groove 6-4. During the installation process, the height position relationship between the base 6-2 and the outer wall panel 2 can be adjusted according to needs. When the upper edge of the vertical plate 8-2 is not in a horizontal state, and the inner wall of the first adjustment groove 6-4 is not in a horizontal state, the assembly of the bottom connecting seat 8 and the first fixing member 6 is prone to produce a large assembly error. In this embodiment, a single first adjustment groove 6-4 is provided on the base 6-2, so that the base 6-2 can rotate at a certain angle relative to the outer wall panel 2, thereby eliminating the error generated when the vertical plate 8-2 and the first plug-in groove 6-1 are assembled, and the base 6-2 is an L-shaped structure, and the bottom of the base 6-2 is adapted to the lower end surface of the outer wall panel 2 to limit the swing angle of the base 6-2 relative to the outer wall panel 2.

[0032] As a preferred embodiment, an opening 6-5 is provided at the top of the first adjustment groove 6-4. During assembly, the connecting screw 4 on the exterior wall panel 2 is installed into the first adjustment groove 6-4 through the opening 6-5, thereby improving the installation convenience of the exterior wall panel 2. A guide surface 6-6 is provided in the opening 6-5, thereby facilitating the installation of the connecting screw 4 on the exterior wall panel 2 into the first adjustment groove 6-4.

[0033] The second fixing member 7 includes a first folding plate 7-2 and a second folding plate 7-3 connected to each other, that is, the second fixing member 7 is Z-shaped, the first folding plate 7-2 is fixed on the outer wall panel 2, and a second plug-in groove 7-1 is formed between the second folding plate 7-3 and the outer wall panel 2.

[0034] A connecting screw 4 is installed on the outer wall panel 2 , and the first fixing member 6 and the second fixing member 7 are connected to the outer wall panel 2 via the connecting screw 4 .

[0035] In order to prevent the connecting screw 4 from separating from the exterior wall panel 2 and causing the exterior wall panel 2 to fall off, a fastener 3 is provided in the exterior wall panel 2, and the connecting screw 4 is connected to the exterior wall panel 2 through the fastener 3. The provision of the fastener 3 facilitates improving the connection strength between the connecting screw 4 and the exterior wall panel 2, thereby improving the connection strength between the exterior wall panel 2 and the steel structure main body 1.

[0036] In this embodiment, the fastener 3 includes a single built-in connecting rod 3-1, and a connecting hole 4-1 is provided on the connecting screw 4. The built-in connecting rod 3-1 is inserted into the connecting hole 4-1. The built-in connecting rod 3-1 cooperates with the connecting hole 4-1 to increase the connection strength between the connecting screw 4 and the exterior wall panel 2. Since the exterior wall panel 2 is connected to the steel structure body 1 through the connecting screw 4, the steel structure connector, and the wall panel connector, the connection strength between the exterior wall panel 2 and the steel structure body 1 is increased by increasing the connection strength of the connecting screw 4 and the exterior wall panel 2. Preferably, the built-in connecting rod 3-1 is a screw, and the connecting hole 4-1 is provided with an internal thread, and the connection stability of the fastener 3 and the connecting screw 4 is ensured by the thread.
