Description

Technical Field

[0001] The present invention relates to the technical field of decoration design. In particular, the present invention relates to a prefabricated steel plate shear wall structure and an installation method. Background Art

[0002] Currently, the decoration industry is developing towards industrialized installation. Generally speaking, wall decoration is a commonly used decoration method in interior design, which can increase the sense of hierarchy of the indoor space and play a role in beautifying the decoration. In particular, the steel plate shear wall has the advantages of light self-weight, high bearing capacity, large initial stiffness, large post-buckling strength, good hysteretic performance, and easy large-scale production, and is a relatively common lateral force resisting member in modern buildings.

[0003] Prefabricated decoration is a newly emerging form of decoration construction in recent years. As the name implies, prefabricated decoration means that each component required for decoration is produced in the factory and then transported to the decoration site for assembly and installation, eliminating the traditional operations such as measurement and cutting of each component at the decoration site. The construction is simpler and more convenient, which can greatly improve the construction efficiency of the decoration site and is a more environmentally friendly decoration construction form. Now, the design and development of prefabricated installation of steel plate shear walls have emerged. For example, Chinese Patent Invention Patent CN112064823A discloses a steel plate shear wall, including a connection component, two barrier components, and a corrugated plate component: the connection component includes a first end plate and a second end plate, the first end plate and the second end plate are parallel and spaced apart from each other, and two chutes are inwardly opened on one side of the second end plate relative to the first end plate, and each chute is arranged along the length direction of the second end plate; the two barrier components are arranged between the first end plate and the second end plate and are respectively arranged on both sides of the first end plate, and the barrier components correspond to the chutes one by one. Each barrier component includes a first fixing plate and a barrier plate, the first fixing plate is connected to the first end plate, one end of the barrier plate is slidably inserted into the chute, and the other end is connected to the first fixing plate; the corrugated plate component includes a corrugated plate, the corrugated plate is arranged between the two barrier plates, and both ends of the corrugated plate are respectively connected to the first end plate and the second end plate. The steel plate shear wall of the present invention is convenient for subsequent decoration.

[0004] However, the above prefabricated steel plate shear wall structure still has the following problems: The steel plate shear wall of a steel structure building needs to be fireproofed. The fireproofing of the steel plate shear wall uses on-site spraying of fireproof coatings as a fireproof measure. The subsequent installation of the decorative layer cannot damage the fireproof coating in any way. It is very difficult to coat the fireproof coating of the above prefabricated steel plate shear wall steel structure, and the installation of the decorative layer is not considered. It is easy to damage the fireproof coating when installing the decorative layer after the coating is applied, resulting in the inability to have both the installation strength of the decorative panel and the fireproof function of the entire shear wall.

[0005] Therefore, to solve the above problems, it is necessary for us to design a reasonable and efficient prefabricated steel plate shear wall structure. Summary of the Invention

[0006] The purpose of the present invention is to provide a prefabricated steel plate shear wall structure, which has a simple structure. By installing a clamping keel and a base keel between the upper beam and the lower beam of the shear wall main body, the installation of the wall panel is completed, and the installation of the wall panel does not damage the fireproof coating on the steel plate surface of the shear wall main body, ensuring that the stable installation of the finish of the steel plate shear wall and the integrity of the fireproof function are simultaneously satisfied.

[0007] To achieve the above purpose, the present invention is realized by adopting the following technical solutions:

[0008] A prefabricated steel plate shear wall structure includes a shear wall main body, a clamping keel arranged on the shear wall main body, a base keel arranged on the clamping keel, and a wall panel arranged on the base keel. The shear wall main body includes an upper beam, a lower beam, and a steel plate arranged between the upper beam and the lower beam. Angle codes for connecting with the ends of the clamping keel are arranged on both the upper beam and the lower beam. A clamping groove is arranged on the side of the clamping keel away from the steel plate. The base keel includes a mounting plate for connecting with the wall panel and a clamping plate for cooperating with the clamping groove.

[0009] As a preference of the present invention, stiffening ribs are arranged on the steel plate, and clamping parts for connecting with the stiffening ribs are arranged on the clamping keel.

[0010] As a preference of the present invention, the clamping part includes a main board, an upwardly warped board, and a downwardly warped board. A clamping plate parallel to the main board is arranged at one end of the downwardly warped board away from the main board. At least a part of the stiffening rib is located between the main board and the clamping plate. Bolt holes for connecting with the clamping keel are arranged on the upwardly warped board.

[0011] As a preference of the present invention, the bolt holes are oblong holes.

[0012] As a preference of the present invention, connecting holes and connecting bolts for inserting into the connecting holes are arranged on both the main board and the clamping plate.

[0013] As a preference of the present invention, the clamping part is an integrally formed sheet metal part.

[0014] As a preference of the present invention, the number of the angle codes, the clamping keel, and the base keel is at least one.

[0015] As a preference of the present invention, paint layers are arranged on the outer sides of both the steel plate and the stiffening ribs.

[0016] The present invention also provides an installation method for an assembled steel plate shear wall structure, comprising the following steps:

[0017] S1: Position at the upper beam and lower beam of the shear wall main body, and install angle codes at the positioning points;

[0018] S2: Vertically install the clamping keel between the upper beam and the lower beam, and connect the end of the clamping keel to the angle code;

[0019] S3: Install the base keel on the clamping keel, so that the clamping plate of the base keel is inserted into the clamping groove of the clamping keel;

[0020] S4: Install the wall panel on the installation plate of the base keel.

[0021] As a preference of the present invention, after performing step S2, connect and fix the clamping keel to the stiffener on the steel plate of the shear wall main body through a clamping member, so that the reinforcing rib is just clamped between the main board and the clamping board of the clamping member, and the upturned board of the clamping member is connected to the clamping keel to reinforce and tie the keel.

[0022] As a preference of the present invention, before performing step S3, paint the outer sides of the steel plate and the stiffener to form a paint layer.

[0023] The beneficial effects of an assembled steel plate shear wall structure and an installation method thereof according to the present invention are as follows: The structure is simple. By installing a clamping keel and a base keel between the upper beam and the lower beam of the shear wall main body, the installation of the wall panel is completed, and the installation of the wall panel does not damage the fireproof coating on the surface of the steel plate of the shear wall main body, ensuring that both the stable installation of the finish of the steel plate shear wall and the integrity of the fireproof function are satisfied simultaneously.

[0034] The following are specific embodiments of the present invention, which further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

In addition, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0038] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way a limitation to the present invention or its application or use.

[0039] Technologies, methods, and systems known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and systems should be regarded as part of the authorization specification.

[0040] Embodiment 1: As Figures 1 to 5 shown, it is merely one of the embodiments of the present invention. An assembled steel plate shear wall structure includes a shear wall main body 1, a clamping keel 2 arranged on the shear wall main body 1, a base keel 3 arranged on the clamping keel 2, and a wall panel 4 arranged on the base keel 3. The shear wall main body 1 includes an upper beam 11, a lower beam 12, and a steel plate 13 arranged between the upper beam 11 and the lower beam 12. Angle codes 21 for connecting with the ends of the clamping keel 2 are arranged on both the upper beam 11 and the lower beam 12. A clamping groove 22 is arranged on the side of the clamping keel 2 away from the steel plate 13. The base keel 3 includes a mounting plate 31 for connecting with the wall panel 4 and a clamping plate 32 for cooperating with the clamping groove 22.

[0041] The shear wall main body 1 adopts an I-shaped module structure, which consists of an upper beam 11, a lower beam 12, and a middle steel plate 13 to form an I-shaped structure. The upper beam 11 is directly connected to the ceiling or cross beam, the lower beam 12 is connected to the ground, and the steel plate 13 constitutes the basic part of the wall. Of course, stiffening ribs 14 can be arranged on the steel plate 13 if the strength needs to be increased. In order to provide fire protection and heat insulation for the steel structure, paint layers need to be arranged on both the outer sides of the steel plate 13 and the stiffening ribs 14, and a coating for fire protection, heat insulation, and corrosion prevention is applied.

[0042] When installing the decorative panel (i.e., the wall panel 4) on the shear wall main body 1, there is no need to install it directly on the steel plate 13, thus avoiding damaging the coating. First, vertically install the clamping keel 2 between the upper beam 11 and the lower beam 12, then install the base keel 3 arranged horizontally on the clamping keel 2, and finally install the wall panel 4 on the base keel 3.

[0043] First, install the clamping keel 2. Angle codes 21 for connecting to the ends of the clamping keel 2 are provided on both the upper beam 11 and the lower beam 12. The clamping keel 2 is vertically arranged, and the length of the clamping keel 2 is equal to the distance between the upper beam 11 and the lower beam 12. The angle code 21 is of an L-shaped structure. One side of the angle code 21 is connected to the lower surface of the upper beam 11 or the upper surface of the lower beam 12 by bolts, and the other side of the angle code 21 is parallel to the clamping keel 2. The end of the clamping keel 2 is fixedly installed and connected to the angle code 21 by bolts. Of course, after the clamping keel 2 is installed, a clamping groove 22 is provided on the side of the clamping keel 2 away from the steel plate 13.

[0044] Next, look at the structure of the base keel 3. The base keel 3 includes a mounting plate 31 for connecting to the wall panel 4 and a clamping plate 32 for cooperating with the clamping groove 22. In fact, clamping plates 32 are provided at both ends of the mounting plate 31. The clamping plates 32 are perpendicular to the mounting plate 31, making the overall base keel 3 form a C-shaped structure. The two clamping plates 32 of the base keel 3 extend and are inserted into the clamping groove 22 of the clamping keel 2 for fixed installation of the base keel 3. Of course, the mounting plate 31 of the base keel 3 is just located on the side of the clamping keel 2 away from the steel plate 13.

[0045] Finally, install the wall panel 4. Just fix the wall panel 4 to the mounting plate 31 by nailing. Of course, when nailing at this time, it will only penetrate the mounting plate 31 and will not damage the steel plate 13, nor affect the coating on the steel plate 13.

[0046] In this way, with the prefabricated installation setting, the installation structure of the wall panel 4 is stable, and it will not affect the stability of the coating on the steel plate 13, ensuring that both the stable installation of the finish of the steel plate shear wall and the integrity of the fire protection function are satisfied.

[0047] For an assembled steel plate shear wall structure of the present invention, its structure is simple. By installing a clamping keel and a base keel between the upper beam and the lower beam of the shear wall main body, the installation of the wall panel is completed, and the installation of the wall panel does not damage the fire protection coating on the steel surface of the shear wall main body, ensuring that both the stable installation of the finish of the steel plate shear wall and the integrity of the fire protection function are satisfied.

[0048] Example 2, as Figures 6 to 9As shown, it is only one embodiment of the present invention. On the basis of Embodiment 1, in an assembled steel plate shear wall structure of the present invention, stiffeners 14 are provided on the steel plate 13, and a clamping member 5 for connecting with the stiffeners 14 is provided on the clamping keel 2.

[0049] In the present invention, the clamping member 5 includes a main board 51, an upwardly warped board 52 and a downwardly warped board 53. One end of the downwardly warped board 53 away from the main board 51 is provided with a clamping plate 54 arranged parallel to the main board 51. At least a part of the stiffener 14 is located between the main board 51 and the clamping plate 54. The upwardly warped board 52 is provided with bolt holes 55 for connecting with the clamping keel 2.

[0050] The upwardly warped board 52 and the downwardly warped board 53 are both perpendicular to the main board 51, and the clamping plate 54 at the lower end of the downwardly warped board 53 is also perpendicular to the downwardly warped board 53, so that a flat plate extends out at the upper end of the whole clamping member 5, and a clamping opening is provided at the lower end. Considering that the stiffeners 14 are provided on the steel plate 13, the stiffeners 14 can just be clamped between the main board 51 and the clamping plate 54 to complete the fixed installation of the clamping member 5. Then, the upwardly warped board 52 is fixedly connected with the clamping keel 2 through bolts and bolt holes 55 to assist in supporting the clamping keel 2.

[0051] It should be noted that the steel plate 13 can be a flat plate, a bent plate or even a corrugated plate. As long as the stiffeners 14 are arranged horizontally or vertically, they can assist in supporting the clamping keel 2.

[0052] Embodiment 3, still as Figures 1 to 9 As shown, it is only one embodiment of the present invention. On the basis of Embodiment 2, in an assembled steel plate shear wall structure of the present invention, the clamping member 5 is a sheet metal part formed integrally, so the auxiliary support structure is more stable.

[0053] Of course, the bolt holes 55 are oblong holes.

[0054] In addition, connecting holes 56 are provided on both the main board 51 and the clamping plate 54, and connecting bolts for inserting into the connecting holes 56 are provided. When the connecting bolts are inserted into the connecting holes 56 on the main board 51 and the clamping plate 54 and then tightened with nuts, the main board 51 and the clamping plate 54 can be clamped towards the middle, so as to clamp the stiffeners 14, and the installation structure is more stable.

[0055] Finally, the number of the angle codes 21, the clamping keels 2 and the base keels 3 is at least one.

[0056] Embodiment 4, only one embodiment of the present invention. On the basis of any of the above embodiments, the present invention also provides an installation method for an assembled steel plate shear wall structure, including the following steps:

[0057] S1: Position at the upper beam and lower beam of the shear wall main body, and install angle brackets at the positioning points.

[0058] S2: Vertically install the clamping keel between the upper beam and the lower beam, and connect the end of the clamping keel to the angle bracket.

[0059] S3: Install the base keel on the clamping keel, so that the clamping plate of the base keel is inserted into the clamping groove of the clamping keel.

[0060] S4: Install the wall panel on the mounting plate of the base keel.

[0061] After performing step S2, connect and fix the clamping keel to the stiffening rib on the steel plate of the shear wall main body through the clamping part, so that the reinforcing rib is just stuck between the main board and the clamping board of the clamping part, and the upturned board of the clamping part is connected to the clamping keel to reinforce and tie the keel.

[0062] Before performing step S3, paint the outside of the steel plate and the stiffening rib to form a paint layer.

[0063] An assembled steel plate shear wall structure and installation method of the present invention has a simple structure. By installing a clamping keel and a base keel between the upper beam and the lower beam of the shear wall main body, the installation of the wall panel is completed, and the installation of the wall panel does not damage the fireproof coating on the surface of the steel plate of the shear wall main body, ensuring that both the stable installation of the finish of the steel plate shear wall and the integrity of the fireproof function are satisfied.

[0064] The present invention is not limited to the above specific embodiments, and the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made based on the technical essence of the present invention to the above embodiments shall be included in the protection scope of the present invention.
