[0002] Prefabricated buildings refer to buildings where a large amount of on-site work in traditional construction methods is transferred to factories. Building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in factories, transported to the construction site, and assembled and installed on-site using reliable connection methods.

[0003] Currently, the exterior walls of prefabricated steel structure buildings are mainly constructed using ordinary aerated concrete blocks and sintered bricks. The construction of these walls requires tasks such as setting out lines, leveling, erecting gauge rods, building the walls, installing tie bars, structural columns, and lintels for doors and windows. This involves a large workload and complex procedures, reducing the construction speed of prefabricated steel structure buildings. Furthermore, when using wall panels as prefabricated exterior walls, it is necessary to pre-reserve openings for doors and windows, and to reinforce these openings and the junctions between them and the wall panels. This results in a cumbersome overall construction process and slow progress, diminishing the advantage of the fast construction speed of prefabricated steel structures. Summary of the Invention

[0047] Example 1

[0048] Combination Figures 1-5 As shown, the external wall structure provided in this embodiment is set between the upper floor slab 8 and the lower floor slab 6. The upper floor steel beam 4 is set below the upper floor slab 8, and the lower floor steel beam 2 is set below the lower floor slab 6.

[0049] The external wall structure includes:

[0050] A fastener 9 is installed through the lower floor slab 6. The lower end of the fastener 9 is fixedly connected to the lower floor steel beam 2, and the upper end of the fastener 9 extends out of the lower floor slab 6 and is higher than the upper surface of the lower floor slab 6 by H cm, where H ≥ 0.8. The number of fasteners 9 is at least two, and multiple fasteners 9 are spaced apart along the length of the outer wall.

[0051] The first wall section 1 is disposed between two adjacent fasteners 9;

[0052] A ring beam 5 extends along the length of the outer wall. The ring beam 5 is fixedly connected to the end of the fixing member 9 away from the steel beam 2 of the lower floor, and multiple fixing members 9 are connected in sequence.

[0053] The second wall section 3 has a wall panel section and a door and window section. The two ends of the second wall section 3 along the height direction of the outer wall are fixedly connected to the ring beam 5 and the upper floor steel beam 4, respectively.

[0054] The ring beam 5 is fixedly connected to the wall panel and the door / window section on the side away from the fastener 9.

[0055] The bottom of the fastener 9 along the height direction of the exterior wall is fixedly connected to the upper flange of the lower floor steel beam 2. As a feasible implementation, the fastener 9 is welded to the lower floor steel beam 2 before the lower floor slab 6 is poured. The fastener 9 includes steel columns, structural steel, and angle steel, preferably steel columns. The upper end of the fastener 9 along the height direction of the exterior wall extends above the upper surface of the lower floor slab 6 after pouring.

[0056] The number of fasteners 9 is at least two, and the number of fasteners 9 can be adjusted adaptively according to the length of the exterior wall. The first wall section 1 is disposed between two adjacent fasteners 9. Along the height direction of the exterior wall, the upper surface of the first wall section 1 is on the same plane as the upper surface of the fastener 9. The lower surface of the first wall section 1 is in contact with the upper surface of the lower floor slab 6 after it has been poured. Along the length direction of the exterior wall, both ends of the first wall section 1 are fixedly connected to the adjacent fasteners 9. The gap between the first wall section 1 and the fasteners 9 is filled with a sealing material 7 to form a tight joint. The sealing material 7 includes wall panel adhesive, sealant, and expanding foam, so that the first wall section 1 and the multiple fasteners 9 form the lower wall of the exterior wall structure.

[0057] The ring beam 5 is horizontally positioned on the side of the fixing member 9 away from the lower floor steel beam 2, and is simultaneously fixedly connected to the sides of multiple fixing members 9 away from the lower floor steel beam 2. Preferably, the ring beam 5 is welded to the multiple fixing members 9. The side of the ring beam 5 near the lower floor steel beam 2 contacts the upper surface of the first wall part 1 along the height direction of the outer wall, wherein the length of the ring beam 5 is adapted to the length of the outer wall. The dimensions of the ring beam 5 and the fixing members 9 along the height direction of the outer wall are determined according to the construction drawings so that the upper surface of the ring beam 5 matches the bottom of the door and window part. After the ring beam 5 is fixed to the fixing members 9, it can serve as a safety protection structure for the floor to ensure the safety of floor construction. It reduces the erection, dismantling, and transportation of temporary guardrails, reduces material usage, and lowers construction costs. By setting the ring beam 5, the seismic resistance of the outer wall structure is improved.

[0058] The second wall section 3 includes the wall panel section and the door and window section. The two ends of the wall panel section along the height direction of the outer wall are fixedly connected to the ring beam 5 and the upper floor steel beam 4, respectively. The two ends of the door and window section along the height direction of the outer wall are fixedly connected to the ring beam 5 and the upper floor steel beam 4, respectively. The two ends of the door and window section along the length direction of the outer wall are fixedly connected to the wall section. The gap between the door and window section and the wall section is filled with a sealing material 7 to form a tight joint. The sealing material 7 includes wall panel adhesive, sealant, and expanding foam. The second wall section 3 is fixedly connected to the side of the ring beam 5 away from the fastener 9 at one end along the height direction of the outer wall, and the gap between the second wall section 3 and the ring beam 5 is filled with a sealing material 7 to form a tight joint. The sealing material 7 includes wall panel adhesive, sealant, and expanding foam. The other end is fixedly connected to the side of the upper floor steel beam 4 away from the upper floor slab 8, and the gap between the second wall section 3 and the upper floor steel beam 4 is filled with a sealing material 7 to form a tight joint. The sealing material 7 includes wall panel adhesive, sealant, and expanding foam. The door / window section and the wall panel section are adapted to form the upper wall of the outer wall structure. By filling the gap with the sealing material 7, the cold bridging effect at the door / window positions of the wall is avoided, as well as water seepage at the door / window positions of the outer wall is prevented.

[0059] The exterior wall structure provided in this embodiment forms a lower wall by fixing multiple fasteners 9 to the lower floor steel beam 2 and setting the first wall part 1 between two adjacent fasteners 9. The upper wall is formed by setting the ring beam 5 on the fasteners 9 and fixing the wall panel part and the door and window part to the upper floor steel beam 4 through the ring beam 5. This simplifies the connection between the door and window and the wall and improves the overall construction speed of the exterior wall.

[0060] Specifically, the first wall portion 1 includes at least one first wall panel 11;

[0061] The exterior wall structure further includes a first reinforcing member 12, which includes a first connecting part 121 and a first limiting part 122. The first connecting part 121 is fixedly connected to the fixing member 9, and the first limiting part 122 is adapted to restrict the first wall panel 11 from moving towards the outside or inside.

[0062] The first wall section 1 between two adjacent fasteners 9 includes at least one first wall panel 11. The gap between adjacent first wall panels 11 is filled with the sealing material 7. The specifications of the first wall panels 11 include various types. The number of first wall panels 11 can be determined according to their specifications and the required size of the first wall section 1, so that the size of the first wall section 1 along the length of the outer wall matches the spacing between the two adjacent fasteners 9, and the size of the first wall section 1 along the height of the outer wall matches the spacing between the lower floor slab 6 and the ring beam 5. In the direction from indoors to outdoors, the thickness of the first wall section 1 matches the thickness of the fastener 9.

[0063] In a preferred embodiment, the first reinforcing member 12 is disposed at the end of the fixing member 9 near the outside. The first connecting portion 121 is fixedly connected to the side of the fixing member 9 facing the first wall panel 11 and near the outside. The fixing connection method includes welding, threaded connection, and riveting. The first limiting portion 122 is angled to the first connecting portion 121 and abuts against the side of the first wall panel near the outside, thereby restricting the movement of the first wall panel 11 towards the outside. Along the height direction of the outer wall, the height of the first reinforcing member 12 matches the height of the fixing member 9 exposed on the lower floor slab 6.

[0064] As an additional implementation, the first reinforcing member 12 is disposed at the end of the fixing member 9 near the interior, wherein the first connecting portion 121 is fixedly connected to the area of ​​the fixing member 9 facing the first wall panel 11 and near the interior, and the fixing connection method includes welding, threaded connection, and riveting. The first limiting portion 122 is set at an angle to the first connecting portion 121, and the first limiting portion 122 abuts against the side of the first wall panel 11 facing the interior, so as to restrict the movement of the first wall panel 11 in the interior direction, and along the height direction of the exterior wall, the height of the first reinforcing member 12 matches the height of the fixing member 9 exposed on the lower floor slab 6.

[0065] In one modified implementation, the first connecting portion 121 and the first limiting portion 122 are located on the same plane. The first connecting portion 121 is fixedly connected to the side of the fixing member 9 facing the outside, and the first limiting portion 122 abuts against the side of the first wall panel 11 near the outside, so as to restrict the movement of the first wall panel 11 in the direction of the outside; or, the first connecting portion 121 is fixedly connected to the side of the fixing member 9 facing the inside, and the first limiting portion 122 abuts against the side of the first wall panel 11 near the inside, so as to restrict the movement of the first wall panel 11 in the direction of the inside.

[0066] Specifically, the exterior wall structure further includes: a first connector 14, which penetrates the first wall panel 11 along the thickness direction of the exterior wall;

[0067] The first connector 14 includes a first hook end 141 and a first limiting end 142. The first hook end 141 contacts the side of the first limiting part 122 away from the first wall panel 11, and the first limiting end 142 abuts against the side of the first wall panel 11 away from the first limiting part 122, so as to restrict the first wall panel 11 from moving away from the first limiting part 122.

[0068] Combination Figure 1 , Figure 2 and Figure 3 As shown, the first connector 14 penetrates the first wall panel 11, wherein the first hook end 141 is located on the side of the first wall panel 11 near the first limiting part 122, and the first limiting end 142 is located on the side of the first wall panel 11 away from the first limiting part 122.

[0069] The first hook end 141 abuts against the side of the first limiting part 122 away from the first wall panel 11. Preferably, the first hook end 141 is welded and fixed to the first limiting part 122 to restrict the first connector 14 from moving away from the first limiting part 122.

[0070] The first limiting end 142 abuts against the side of the first wall panel 11 away from the first limiting part 122, and is combined. Figure 3As shown, in one feasible implementation, the first limiting end 142 is a threaded rod with a nut on it. By rotating the nut, its position on the threaded rod is adjusted, thereby causing the nut to press against the side of the first wall panel 11 away from the first limiting part 122, thus restricting the first wall panel 11 from moving away from the first limiting part 122. The first connecting member 14 restricts the relative position of the first wall panel 11 and the first reinforcing member 12 via the first hook end 141 and the first limiting end 142. Preferably, a first groove is recessed on the side of the first wall panel 11 away from the first hook end 141, corresponding to the position of the first limiting end 142. The first limiting end 142 abuts against the bottom surface of the first groove near the first hook end 141. The first groove is adapted to allow the projection of the first limiting end 142 along the direction of gravity to be located inside the first wall panel 11. Additionally, a washer may be provided on the first limiting end 142, and the washer is located on the side of the nut close to the first hook end 141. The nut abuts against the side of the first wall plate 11 away from the first limiting part 122 via the washer, thereby enhancing the abutment stability between the nut and the first wall plate 11.

[0071] As an additional implementation, the first limiting end 142 may be provided with a pin hole, the position of which is adapted to the thickness of the first wall panel 11. By inserting a pin into the pin hole, the pin abuts against the side of the first wall panel 11 away from the first limiting part 122, thereby restricting the first wall panel 11 from moving away from the first limiting part 122.

[0072] The exterior wall structure provided in this embodiment restricts the relative position of the first wall panel 11 and the first reinforcement member 12 through the first connector 14, thereby forming a fixed connection between the first wall panel 11 and the fixing member 9, which simplifies the process, enhances the connection stability, and helps to improve the construction speed.

The second connecting part 321 is fixedly connected to the ring beam 5, and the second limiting part 322 is adapted to restrict the movement of the end of the second wall panel 31 near the ring beam 5 towards the outside or inside.

[0074] The specifications of the second wall panel 31 include various types, and the number of the second wall panels 31 can be determined according to their specifications and the required dimensions of the wall panel section, so as to make the wall panel section and the door and window section together form the second wall section 3, and to make the dimensions of the second wall section 3 match the dimensions between the ring beam 5 and the upper floor steel beam 4.

[0075] In a preferred embodiment, the second reinforcement member 32 is disposed at the end of the ring beam 5 near the outside. The second connecting portion 321 is fixedly connected to the side of the ring beam 5 facing the second wall panel 31 and near the outside.

The second limiting portion 322 is set at an angle to the second connecting portion 321 and abuts against the side of the second wall panel 31 near the outside to restrict the movement of the second wall panel 31 in the direction of the outside. Along the length of the outer wall, the length of the second reinforcement member 32 matches the length of the ring beam 5.

[0076] As an additional implementation, the second reinforcement member 32 is disposed at the end of the ring beam 5 near the interior. The second connecting portion 321 is fixedly connected to the side of the ring beam 5 facing the second wall panel 31 and near the interior. The fixing connection method includes welding, threaded connection, and riveting.

[0082] The second limiting end 342 abuts against the side of the second wall panel 31 away from the second limiting part 322, and is engaged. Figure 5 As shown, in one feasible implementation, the second limiting end 342 is a threaded rod with a nut on it. By rotating the nut, its position on the threaded rod is adjusted, thereby causing the nut to press against the side of the second wall panel 31 away from the second limiting part 322, thus restricting the movement of the second wall panel 31 away from the second limiting part 322. The second connecting member 34 restricts the relative position of the second wall panel 31 and the second reinforcing member 32 via the second hook end 341 and the second limiting end 342.

The second limiting end 342 abuts against the bottom surface of the second groove near the second hook end 341. The second groove is adapted to allow the projection of the second limiting end 342 along the direction of gravity to be located inside the second wall panel 31. Additionally, a washer may be provided on the second limiting end 342, and the washer is located on the side of the nut near the second hook end 341. The nut abuts against the side of the second wall plate 31 away from the second limiting part 322 via the washer, thereby enhancing the abutment stability between the nut and the second wall plate 31.

[0083] As an additional implementation, the second limiting end 342 may be provided with a pin hole, the position of which is adapted to the thickness of the second wall panel 31. By inserting a pin into the pin hole, the pin abuts against the side of the second wall panel 31 away from the second limiting part 322, thereby restricting the movement of the second wall panel 31 away from the second limiting part 322.

[0084] The exterior wall structure provided in this embodiment restricts the relative position of the second wall panel 31 and the second reinforcement member 32 through the second connector 34, and is fixedly connected to the ring beam 5 through the second reinforcement member 32, thereby forming a fixed connection between the second wall panel 31 and the ring beam 5, which simplifies the process, enhances the connection stability, and helps to improve the construction speed.

[0085] Specifically, the exterior wall structure also includes a third reinforcement component 37, which includes a third connecting part 371 and a third limiting part 372. The third connecting part 371 is fixedly connected to the upper floor steel beam 4, and the third limiting part 372 is adapted to restrict the second wall panel 31 from moving towards the outside or inside from the end near the upper floor steel beam 4.

[0086] In a preferred embodiment, the third reinforcement member 37 is disposed at the end of the upper floor steel beam 4 near the outside. The third connecting portion 371 is fixedly connected to the side of the upper floor steel beam 4 facing the second wall panel 31 and near the outside. The fixing connection method includes welding, threaded connection, and riveting. The third limiting portion 372 is angled to the third connecting portion 371 and abuts against the side of the second wall panel 31 near the outside to restrict the movement of the second wall panel 31 towards the outside. Along the length of the outer wall, the length of the third reinforcement member 37 matches the length of the upper floor steel beam 4.

[0087] As an additional implementation, the third reinforcement member 37 is disposed at the end of the upper floor steel beam 4 near the interior. The third connecting portion 371 is fixedly connected to the side of the upper floor steel beam 4 facing the second wall panel 31 and near the interior. The fixing connection method includes welding, threaded connection, and riveting. The third limiting portion 372 is angled to the third connecting portion 371 and abuts against the interior-facing side of the second wall panel 31 to restrict movement of the second wall panel 31 towards the interior. Along the length of the exterior wall, the length of the third reinforcement member 37 matches the length of the upper floor steel beam 4.

[0088] In one modified implementation, the third connecting part 371 and the third limiting part 372 are located on the same plane. The third connecting part 371 is fixedly connected to the side of the upper floor steel beam 4 facing the outside, and the third limiting part 372 abuts against the side of the second wall panel 31 near the outside, so as to restrict the movement of the second wall panel 31 in the direction of the outside; or, the third connecting part 371 is fixedly connected to the side of the upper floor steel beam 4 facing the inside, and the third limiting part 372 abuts against the side of the second wall panel 31 near the inside, so as to restrict the movement of the second wall panel 31 in the direction of the inside.

[0090] The third connector 38 includes a third hook end 381 and a third limiting end 382. The third hook end 381 contacts the side of the third limiting part 372 away from the second wall panel 31, and the third limiting end 382 abuts against the side of the second wall panel 31 away from the third limiting part 372, so as to restrict the second wall panel 31 from moving away from the second limiting part 322.

[0091] Combination Figure 1 and Figure 4 As shown, the third connector 38 penetrates the second wall panel 31, wherein the third hook end 381 is located on the side of the second wall panel 31 near the third limiting part 372, and the third limiting end 382 is located on the side of the second wall panel 31 away from the third limiting part 372.

[0092] The third hook end 381 abuts against the side of the third limiting part 372 away from the second wall panel 31. Preferably, the third hook end 381 is welded and fixed to the third limiting part 372 to restrict the third connector 38 from moving away from the third limiting part 372.

[0093] The third limiting end 382 abuts against the side of the second wall panel 31 away from the third limiting part 372, and is combined. Figure 4As shown, in one feasible implementation, the third limiting end 382 is a threaded rod with a nut on it. By rotating the nut, its position on the threaded rod is adjusted, thereby causing the nut to press against the side of the second wall panel 31 away from the third limiting part 372, thus restricting the movement of the second wall panel 31 away from the third limiting part 372. The third connector 38 restricts the relative position of the second wall panel 31 and the third reinforcement part 37 via the third hook end 381 and the third limiting end 382. Preferably, a third groove is formed on the side of the second wall panel 31 away from the third hook end 381, corresponding to the position of the third limiting end 382. The third limiting end 382 abuts against the bottom surface of the third groove near the third hook end 381. The third groove is adapted to allow the projection of the third limiting end 382 along the direction of gravity to be located inside the second wall panel 31. Additionally, a washer may be provided on the third limiting end 382, ​​and the washer is located on the side of the nut close to the third hook end 381. The nut abuts against the side of the second wall plate 31 away from the third limiting part 372 via the washer, thereby enhancing the abutment stability between the nut and the second wall plate 31.

[0094] As an additional implementation, the third limiting end 382 may be provided with a pin hole, the position of which is adapted to the thickness of the second wall panel 31. By inserting a pin into the pin hole, the pin abuts against the side of the second wall panel 31 away from the third limiting part 372, thereby restricting the movement of the second wall panel 31 away from the third limiting part 372.

[0095] The exterior wall structure provided in this embodiment restricts the relative position of the second wall panel 31 and the third reinforcement member 37 through the third connector 38, and is fixedly connected to the upper floor steel beam 4 through the third reinforcement member 37, thereby forming a fixed connection between the second wall panel 31 and the upper floor steel beam 4, which simplifies the process, enhances the connection stability, and helps to improve the construction speed.
