Description

Technical Field

[0001] A steel plate shear wall and its installation method of the present invention relate to the field of prefabricated partitions. Background Art

[0002] Traditional partitions mostly adopt the treatment method of cement mortar, which has problems such as more wet operations, long construction period, cumbersome process, large workload, large pollution at the construction site, easy occurrence of hollowing and cracking of the partition wall, and it is very difficult to carry out later maintenance and repair. For this reason, prefabricated steel plate shear walls have been more and more widely used in the market. However, the existing steel plate shear wall solutions are too cumbersome. For example, a prefabricated interior partition wall structure based on a composite insulation wall panel disclosed in CN202022359845.3 includes an interior partition wall; a second C-shaped steel keel with an outward opening is welded on the head side of the interior partition wall. Correspondingly, a first C-shaped steel keel is fixedly installed on the wall surface perpendicular to and close to the head side of the interior partition wall through cavity bolts. The first C-shaped steel keel has an outward opening, and a thermal insulation inner core is filled in the opening of the first C-shaped steel keel; the head of the interior partition wall is inserted into the first C-shaped steel keel, and the interior partition wall and the first C-shaped steel keel are fixed by self-tapping screws; a second C-shaped steel keel with an inward opening is welded on the tail side of the interior partition wall. Correspondingly, an L-shaped vertical keel is fixedly installed on the wall surface perpendicular to and close to the tail side of the interior partition wall through cavity bolts, and the tail of the interior partition wall is fixed to the L-shaped vertical keel by self-tapping screws. However, although it is efficient enough to be prefabricated in the factory and then transported to the site for assembly, its assembly effect is not good, the connection strength is insufficient, and the flatness of the wall surface cannot be guaranteed. Therefore, it is necessary to make improvements. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a steel plate shear wall with a simple overall structure, convenient installation, and meeting the characteristics of fast installation and disassembly of prefabrication.

[0004] To solve the above technical problems, the present invention adopts the following technical solutions:

[0009] There are multiple fasteners, which are arranged corresponding to the connectors. The fasteners are connected to the connectors to fix the adapter on the horizontal keel assembly.

[0010] The decorative panel is connected to the adapter.

[0011] Furthermore, the horizontal keel assembly includes a number of U-shaped keels, which are distributed at intervals along the horizontal direction on the inner wall of the steel structure. The U-shaped keel is provided with two relatively arranged side bodies and a front body vertically connecting the two side bodies. The end of the side body is welded and fixed to the inner wall.

[0012] Furthermore, the connector includes a screw rod with a cylindrical shape and a threaded surface and a nut with a hexagonal shape and a threaded hole in the middle.

There are multiple of them, and their positions correspond one by one to the positions of the horizontal keel assembly. The open end of the secondary keel faces the horizontal keel assembly. The secondary keel is clamped on the horizontal keel assembly, and the back of the secondary keel fits against the flat body of each fastener.

[0019] This solution also provides an installation method for a steel plate shear wall, including the following steps:

[0034] The present invention will be further described below in conjunction with the accompanying drawings of the specification and specific embodiments. Those of ordinary skill in the art will be able to implement the present invention based on these descriptions. In addition, the embodiments of the present invention referred to in the following description are generally only a part of the embodiments of the present invention, rather than all of the embodiments. Therefore, all other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts should fall within the scope of protection of the present invention.

[0035] As Figures 1 to 4 shown, a steel plate shear wall includes:

[0036] A plurality of horizontal keel assemblies, the horizontal keel assemblies are arranged horizontally, and a plurality of horizontal keel assemblies are distributed at intervals in the vertical direction on the inner wall;

[0037] A plurality of connectors 1 are provided on the horizontal keel assembly, and a plurality of connectors 1 are distributed at intervals in the horizontal direction;

[0038] A plurality of adapter pieces 2, the adapter pieces 2 correspond to the horizontal keel assemblies one by one, and connection holes 2-1 provided with corresponding connectors 1 are provided on the adapter pieces 2. The adapter pieces 2 are installed on the adapter pieces 2 after corresponding to the positions of the connectors 1 on the horizontal keel group;

[0039] A plurality of fasteners 3, the fasteners 3 are correspondingly arranged with the connectors 1, and are connected to the connectors 1 to fix the adapter pieces 2 on the horizontal keels;

[0040] A decorative panel (not shown in the figure), and the decorative panel is connected to the adapter piece 2 by hanging or other means.

[0041] The installation method of the steel plate shear wall is as follows:

[0042] 1. Select a corresponding number of horizontal keel assemblies and install them on the inner wall at vertical intervals;

[0043] 2. Install the adapter piece 2 according to the position of the connector 1 on the horizontal keel assembly;

[0044] 3. Fix the fastener 3 to the connector 1;

[0045] 4. Install the decorative panel on the adapter piece 2.

[0046] It should be noted that the steel plate shear wall referred to in this embodiment and the steel plate shear wall shown in the accompanying drawings are only one piece of a wall. According to the actual situation, the steel plate shear wall in this embodiment can be replicated horizontally to form a complete partition wall.

[0047] Preferably, the horizontal keel assembly includes a number of U-shaped keels 4, which are horizontally and spacedly distributed on the inner wall of the steel structure. It has two relatively arranged side bodies 4-1 and a front body 4-2 vertically connecting the two side bodies 4-1. The end of the side body 4-1 is fixed to the inner wall of the steel structure by welding. In another embodiment, the end of the side can also extend horizontally, then holes are drilled on the extended edge, and then it is fixed to the inner wall by screws. However, in this embodiment, welding is preferably used for fixation to enhance the connection strength and reduce the material consumption.

[0048] It should be noted that another function of the side body 4-1 of the U-shaped keel 4 is to separate the inner wall from the decorative panel by a certain distance, so that the inside of the steel plate shear wall is hollow, achieving the effects of sound insulation, heat preservation, moisture proof and heat insulation.

[0049] In this embodiment, as an alternative embodiment, the U-shaped keel 4 can be manufactured by first punching a row of holes in the middle of a metal plate, then folding it twice, and then cutting it into several small pieces. Among them, a row of pre-punched holes in the middle of the metal plate is used to form a positioning hole 4-21 on the front body 4-2 of each U-shaped keel 4, and the positioning hole 4-21 is used to position and install the connecting piece 1.

[0050] In this embodiment, the connecting piece 1 includes a screw rod with a cylindrical shape and a threaded surface and a nut with a hexagonal shape and a threaded hole in the middle. The nut is connected to the connecting piece 1. The connecting piece 1 passes through from the inside of the front body 4-2 of the U-shaped keel 4, and the nut fits against the inside of the front body 4-2. The nut and the screw rod are fixed to the front body 4-2 by welding. As another alternative embodiment, the connecting piece 1 may not include a nut, but a single screw rod, and the screw rod can be directly welded to the surface of the front body 4-2 of the U-shaped keel 4. However, considering the uniformity of the positions of the connecting pieces 1 on each U-shaped keel 4, it is preferred to use the connecting piece 1 composed of a screw rod and a nut. This preferred embodiment can not only cooperate with the positioning hole 4-21 of the U-shaped keel 4 to accurately position its own installation position, but also expand the welding area with the U-shaped keel 4 and increase its connection strength.

[0051] In this embodiment, the shape of the adapter 2 corresponds to the arrangement mode and quantity of the horizontal keel assembly. It is strip-shaped and can cover the horizontal keel assembly. The connection hole 2-1 on it is in a waist shape and its position can be adjusted horizontally to facilitate its installation on the horizontal keel assembly.

[0052] The material of the adapter 2 is selected as wood. As a common material, wood has the advantages of low cost. And more importantly, wood is softer, and when the subsequent decorative panel is hung on the adapter 2, it can be clamped more tightly.

[0053] In this embodiment, as an alternative implementation, the fastener 3 is a nut with a threaded hole in the middle of a hexagonal shape. The nut can be threadedly connected to the connecting member 1 to lock the adapter 2 onto the horizontal keel assembly. It should be noted that the selection of the wooden adapter 2 also takes into account the connection of the fastener 3. Because the wood is relatively soft, the nut can be screwed tightly, causing the wooden adapter 2 to be squeezed and generate a reaction force, greatly increasing the friction force with the fastener 3, thereby preventing the nut from loosening and improving the connection strength.

[0054] As another alternative implementation, the fastener 3 includes a cylindrical main body 3-1. One side of it has a threaded hole, and the other side is a flat body 3-2 that expands relative to the cylindrical main body 3-1. The flat body 3-2 serves as a point position. By rotating the fastener 3, the distance between it and the inner wall can be adjusted. Through the position adjustment of each point position, the flatness adjustment of the decorative panel can be achieved.

[0055] Specifically, the present invention further includes a U-shaped secondary keel 5. The secondary keel 5 is fixed to the back of the decorative panel. There are multiple of them, and their positions correspond one by one to the positions of the horizontal keel assembly. The open end of the secondary keel 5 faces the horizontal keel assembly, and the secondary keel 5 can be snap-connected to the horizontal keel assembly, so that the decorative panel is mounted on the horizontal keel assembly. And the back of the secondary keel 5 fits the plane of each fastener 3 to maintain the flatness of the decorative panel.

[0056] As described above, only the specific implementation manners of the present invention are provided, but the protection scope of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes not only the content described in the drawings and the above specific implementation manners. Any modification that does not deviate from the functional and structural principles of the present invention will be included in the scope of the claims.
