Detailed Description of the Invention

[0029] The following are specific embodiments of the present invention. In combination with the accompanying drawings, the technical solutions of the present invention will be further described, but the present invention is not limited to these embodiments.

[0030] Embodiment 1

[0031] A double-layer vertical keel partition wall, which is the same as the traditional partition wall, includes a keel frame and wall panels. By sequentially installing the keel frame and wall panels on the fixing structure, the partition wall can be obtained. The difference is that in this application, at least two layers of keel frames are provided to install wall panels on both sides of the fixing structure respectively and improve the support effect on the wall panels.

[0032] Among them, the fixing structure is a frame body, such as Figure 2 and Figure 3 shown. The frame body includes a pair of horizontal fixing members 111 and a pair of vertical fixing members. The horizontal fixing member 111 refers to a member with a horizontal length direction, and the vertical fixing member refers to a member with a vertical length direction. The two horizontal members and the two vertical members are sequentially connected end to end to form a square frame body. The specific structures of the horizontal fixing member 111 and the vertical fixing member are not limited, and various common keels on the market can be used, such as square tube keels, I-shaped keels, C-shaped keels, etc. can be independently used respectively. In this embodiment, considering the installation effect of the subsequent wall panels, both vertical fixing members are selected as square tube keels, which have flat side plates and can be used to install wall panels on both sides respectively. And the two side plates are connected by two connecting plates, which has good support strength; while both horizontal fixing members 111 are selected as I-shaped keels, also known as H-shaped keels, which also have flat side plates and are convenient for installation. At the same time, based on its I-shaped structure, compared with square tube keels and C-shaped keels, both ends have flanges, which is convenient for subsequent balanced lap joint installation. The horizontal fixing member 111 and the vertical fixing member can be fixed together in various ways. For example, the end face of the horizontal fixing member 111 can be directly welded to the side face of the vertical fixing member; it can also be that after the horizontal fixing member 111 and the vertical fixing member are spliced, gusset plates are respectively added on both sides of their connection, and one gusset plate is welded to both the side face of the horizontal fixing member 111 and the side face of the vertical fixing member; the above two connection methods can also be used simultaneously.

[0033] In this embodiment, considering that the square frame body has instability problems, an inclined support 12 is also provided on the diagonal line of the frame body to divide the direction frame body into two triangular frames. As Figure 2As shown, the frame body includes four joints at the upper left, upper right, lower left, and lower right. The diagonal brace 12 is disposed on the diagonal of the frame body, that is, the two ends of the diagonal brace 12 are respectively connected to the upper left and lower right joints, or the two ends of the diagonal brace 12 are respectively connected to the upper right and lower left joints. In this embodiment, the latter is adopted. Therefore, at the upper left and lower right joints, the direct welding method of the end face of the horizontal fixing member 111 and the side face of the vertical fixing member can be used directly; at the upper right and lower left joints, on the basis of direct welding, gusset plates are respectively added on both sides of each joint. One gusset plate is welded to the horizontal fixing member 111, the vertical fixing member, and the diagonal brace 12, which plays a role in strengthening and installing the diagonal brace 12. A partition 54 is also installed on the frame body. The partition 54 is usually a floor slab, and the partition 54 is mainly installed on the lower horizontal fixing member 111. In order to improve the supporting strength of the partition 54, the partition 54 is lapped on the top of the horizontal fixing member 111.

[0034] In order to be able to install wall panels on the opposite sides of the frame body respectively, the present application includes a plurality of keel assemblies 2 arranged in sequence along the length direction of the horizontal fixing member 111, such as Figure 1 As shown, the keel assembly 2 includes at least two vertical keels 21 arranged in sequence along the width direction of the horizontal fixing member 1. In this embodiment, a keel assembly 2 includes two vertical keels 21, thus forming a double-layer keel frame.

[0035] Both ends of the vertical keel 21 need to be respectively connected to the two horizontal fixing members 111. In this embodiment, due to the block of the diagonal brace 12, a whole vertical keel 21 in the traditional solution needs to be cut into the upper and lower vertical segments in the present application. During installation, the upper and lower vertical segments are installed on the same straight line. At this time, the two ends in the length direction of the upper vertical segment or the lower vertical segment are respectively connected to the horizontal fixing member 111 and the diagonal brace 12. Due to the different distances between the horizontal fixing members 111 and the diagonal brace 12 at different positions, the lengths of the respective vertical segments are different, and generally, they are cut to obtain the required length after measurement at the assembly site. The structure of the vertical keel 21 is not limited, but at least includes a flat side plate. During installation, the side plate is adjusted to be outside and parallel to the vertical plane for installing the wall panel. The vertical keel 21 can be a square tube keel, an I-shaped keel, or a U-shaped keel. In this embodiment, a U-shaped keel is adopted, which includes a bottom plate and side plates respectively arranged at both ends of the bottom plate.

[0036] The connection method between the vertical segment and the horizontal fixing member 111 and the diagonal brace 12 is not limited, and can be screw fixation, welding, etc. In this embodiment, considering that fireproof coatings are provided on the horizontal fixing member 111 and the diagonal brace 12, especially on their surfaces, in order to avoid damage to the fireproof coatings. The vertical segment is connected to the diagonal brace 12 through a hoop structure and connected to the horizontal fixing member 111 through a limiting structure, as follows.

[0037] Such as Figure 2and Figure 3 As shown, the upper and lower vertical sections of the vertical keel 21 are connected to the horizontal fixing member 111 through a limiting structure. Figure 6 As shown, the limiting structure includes a limiting seat 51, which is U-shaped and includes a first fixing portion 511 connected to the horizontal fixing piece 111 and limiting portions 512 respectively arranged at both ends of the first fixing portion 511. A U-shaped slot is formed between the first fixing portion 511 and the limiting portion 512. The bottom end of the lower vertical section of the vertical keel 21 or the top end of the upper vertical section is inserted into the slot. The side surface of the vertical keel 21 can be welded and fixed to the limiting portion 512 to achieve the fixation of the vertical keel 21; the end surface of the vertical keel 21 can also be welded and fixed to the first fixing portion 511; as in the present embodiment, considering the installation of subsequent wall panels and the stable installation of the vertical keel 21 Therefore, firstly, a gap is formed between the vertical keel 21 and the limiting portion 512 for the wall panel to be inserted, and then a support member 52 is added between the two vertical keels 21 of each group of keel components 2 to fix the vertical keel 21 and adjust the distance between the two keel frames. The support member 52 is also arranged in the slot, including a second fixing portion 521 connected to the first fixing portion 511, and support portions 522 respectively arranged at both ends of the second fixing portion 521. The first fixing portion 511 and the second fixing portion 521 are overlapped and fixed by expansion screws. The two support portions 522 are respectively overlapped with the outer side surfaces of the two vertical keels 21 adjacent to each other along the width direction of the transverse fixing member 111 and then welded.

[0038] In the lower transverse fixing member 111, since the partition 54 is overlapped on the transverse fixing member 111, the first fixing portion 511 here is actually connected to the partition 54. The transverse fixing member 111 is provided with a fire-resistant coating, but the partition is usually made of concrete and does not need to be provided with a fire-resistant coating. Therefore, the first fixing portion 511 can be directly placed on the partition 54 and connected by expansion bolts.

[0039] In the upper transverse fixing member 111, since there is no partition structure between it and the vertical keel 21, in order to avoid the first fixing portion 511 from damaging the installation layer on the transverse fixing member 111, the present embodiment adds a lap joint 53 structure. Figure 7 As shown, first, the horizontal fixing member 111 is selected as an I-shaped keel. This I-shaped keel includes a parallel top plate and a bottom plate, and the top plate and the bottom plate are connected by a vertical plate, so that the two ends of the top plate form folded edges 111a, and the two ends of the bottom plate also form folded edges 111a. Considering that the upper horizontal fixing member 111 is also a receiving horizontal fixing member 111 of the upper partition 54, the lap joint 53 is overlapped with the two folded edges 111a of the bottom plate of the horizontal fixing member 111. Figure 7 and Figure 8As shown, the overlapping member 53 first includes a first overlapping portion 531 disposed on the side of the folded edge 111a away from the vertical keel 21. This arrangement can be an overlap, so that the fireproof coating on the folded edge 111a will not be damaged. At the same time, for the convenience of subsequent connection, a first mounting portion 532 is non-parallelly connected to the first overlapping portion 531. For the purpose of improving the strength, it is preferably perpendicularly connected between the two. Cooperating with the first mounting portion 532, there is also a second mounting portion 534 connected to the first fixing portion 511. By overlapping the first mounting portion 532 and the second mounting portion 534 and then connecting them with screws, the first fixing portion 511 can be mounted on the transverse fixing member 111. Further, in order to improve the connection strength between the vertical second mounting portion 534 and the horizontal first fixing portion 511, a second overlapping portion 533 is additionally provided. After the second overlapping portion 533 is overlapped with the outer side surface of the first fixing portion 511 and then connected, the installation of the second mounting portion 534 on the first fixing portion 511 is completed.

[0040] The upper and lower vertical sections of the vertical keel 21 also need to be connected to the inclined support 12 through a hoop structure respectively. This hoop structure includes a hoop ring sleeved on the inclined support 12. The hoop ring is a detachable structure, including a first half-ring and a second half-ring. The first half-ring and the second half-ring each have two ends, and at least one end of the first half-ring is detachably connected to the end of the second half-ring. For example: it can be that the lower end of the first half-ring is hinged to the lower end of the second half-ring, and flanging plates are respectively provided at the upper end of the first half-ring and the upper end of the second half-ring, and the two flanging plates are detachably connected by a screw-nut structure; it can also be that flanging plates are provided at both ends of the first half-ring and both ends of the second half-ring, and the flanging plates at both ends are respectively detachably connected by a screw-nut structure; in this embodiment, the latter structure with detachable ends is adopted to facilitate adapting to inclined supports 12 with different widths. The shapes of the inner surfaces of the first half-ring and the second half-ring should match the shape of the outer surface of the inclined support 12. For example, when the inclined support 12 is a circular tube column, the inner surfaces of the first half-ring and the second half-ring are arc-shaped; when the inclined support 12 is a square tube column, the inner surfaces of the first half-ring and the second half-ring are U-shaped. Since when the inclined support 12 is a circular tube column, the hoop ring is prone to rotate on the inclined support 12, affecting the position of the connection structure of the hoop ring flanging plate, and further affecting the installation position of the subsequent vertical section, therefore, in this embodiment, the inclined support 12 is a square tube. At the same time, based on the first half-ring and the second half-ring, in this embodiment, the two vertical keels 21 of each keel assembly 2 are respectively connected to the first half-ring and the second half-ring to balance the force received by the hoop ring. The vertical keel 21 can be directly welded to the hoop ring at its end, but considering that the solid area of the end of the vertical keel 21 is small, affecting the welding strength, therefore, in this embodiment, the hoop structure further includes a connector for connecting the vertical keel 21 and the hoop ring. The connector includes a first connecting portion that overlaps and connects with the vertical keel 21, and a second connecting portion that overlaps and connects with the outer surface of the hoop ring. The connector can be L-shaped. The first connecting portion can be welded after overlapping with the bottom plate or side plate of the U-shaped vertical keel 21. When overlapping, it can overlap with the inner side or outer side of the bottom plate, or the inner side or outer side of the side plate. The connector can also be U-shaped, including two first connecting portions. The two first connecting portions are respectively welded after overlapping with the two side plates of the vertical keel 21. In this embodiment, a U-shaped connector is adopted to improve the connection strength between the vertical keel 21 and the connector. Specifically when connecting, the two first connecting portions can be respectively independently connected to the inner side or outer side of the side plate. In this embodiment, the side plate of the vertical keel 21 facing outward and used for subsequent connection with the wall panel is connected to the first connecting portion through the inner side to ensure its flat side; correspondingly, in order to ensure the balance and stability of the connection between the vertical keel 21 and the connector, the inner side plate of the vertical keel 21 is also connected to the other connecting portion through the inner side. The second connecting portion is a shape that matches the outer surface of the hoop ring. In this embodiment, it is sufficient to select a flat plate structure for the second connecting portion.

[0041] In the above manner, several groups of keel components 2 can be installed into the frame body. Since there are gaps between the vertical keels 21, if wall panels are directly installed thereon, the wall panel part located in the gap will not be supported and is prone to breakage under stress. Therefore, in this embodiment, as Figure 4 shown, a plate member 22 is provided between two adjacent vertical keels 21 along the length direction of the transverse fixing member 111. The plate member 22 can be directly cut into the desired shape and then clamped between the two vertical keels 21. When necessary, an adhesive can be added for reinforcement. The plate member 22 can be selected as a thermal insulation board, such as a rock wool board, which not only plays a supporting role but also has the functions of heat preservation and sound insulation. The plate surface of the plate member 22 is preferably flush with the installation surface of the vertical keel 21 for connecting with the wall panel, that is, the outer side surface. The outer side surface of the vertical keel 21 and the plate surface of the plate member 22 together form a vertical surface to ensure the flatness of the subsequent installation of the wall panel 3.

[0042] Then, the wall panel can be installed. The wall panel can be selected as a gypsum board. As mentioned above, a gap is reserved between the vertical keel 21 and the limiting portion 512 in the limiting seat 51. When installing the wall panel, the upper and lower ends of the wall panel can be directly inserted into the gaps in the upper and lower limiting seats 51 respectively. To further ensure the installation stability of the wall panel, the wall panel and the vertical keel 21 can also be fixed by screwing.

[0043] Embodiment 2

[0044] This embodiment is basically the same as Embodiment 1, and the difference lies only in that:

[0045] As Figure 9 shown, the frame body does not have a diagonal brace. The vertical keel 21 is a whole keel, and its two ends are respectively connected to the transverse fixing member 111. The connection method and structure are the same as those in Embodiment 1, that is, in each group of keel components 2, the upper ends of the two vertical keels 21 are connected by a support member 52 and then inserted together into the card slot of the limiting seat 51. The first fixing portion 511 of the limiting seat 51 is connected to the folded edge 111a of the transverse fixing member 111 through a lapping member 53; the lower ends of the two vertical keels 21 are also connected by a support member 52 and then inserted together into the card slot of the limiting seat 51. The first fixing portion 511 of the limiting seat 51 and the partition plate 54 lapped on the transverse fixing member 111 are connected by an expansion bolt.

[0046] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art of the present invention can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
