Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0036] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0037] The present application embodiment provides a connection structure between a wall and a support column, such as Figures 1 to 5 As shown, the connection structure between the wall and the support column includes a first wall 1, a second wall 2 and a support column assembly 3, and the first wall 1 and the second wall 2 are connected through the support column assembly 3; the support column assembly 3 includes a first connecting column 31, a second connecting column 32 and a first L-shaped column 33, the first connecting column 31 is fixed to the end of the first wall 1, the second connecting column 32 is fixed to the end of the second wall 2, and the two ends of the first L-shaped column 33 are respectively fixed to the first end of the first connecting column 31 and the first end of the second connecting column 32; the first connecting column 31, the second connecting column 32 and the first L-shaped column 33 are surrounded to form an L-shaped cavity 35 with a notch on one side.

[0038] The first connecting column 31 , the second connecting column 32 and the first L-shaped column 33 may all be steel columns.

[0039] The first wall 1 and the second wall 2 are connected by a support column assembly 3, and the angle between the first wall 1 and the second wall 2 is 90°, that is, the first wall 1 and the second wall 2 are perpendicular to each other. The first wall 1 and the second wall 2 can be walls with exactly the same structure and size, or walls with different widths (e.g., the width of the first wall 1 is greater than the width of the second wall 2).

[0040] In the factory, the first wall 1 and the first connecting column 31 are fixed in advance to form a wall module as the minimum transport unit. Similarly, the second wall 2 and the second connecting column 32 are fixed to form a wall module as the minimum transport unit. The formed wall module is a plane structure and can be stacked in multiple layers for transportation, which greatly improves the transportation efficiency, does not require special vehicles for special transportation, and reduces transportation costs.

[0041] The first connecting column 31 fixed on the first wall 1 and the second connecting column 32 fixed on the second wall 2 are connected with the first L-shaped column 33 on site to form a support column assembly 3. In other words, the support column assembly 3 is a multi-component form formed by splicing.

[0042] The support column assembly 3 formed by splicing is a hollow structure, that is, the support column assembly 3 is formed with an L-shaped cavity 35 for pouring concrete. After the wall and the support column are connected, concrete is poured into the cavity of the support column assembly 3 to improve the strength. It should be noted that in the on-site construction, the inner side of the first wall 1 and the second wall 2 will be provided with an inner wall board (cement board), and the inner wall board can block the gap of the L-shaped cavity to form an L-shaped cavity closed on all sides, so as to facilitate the pouring of concrete without leakage. In the connection structure between the wall and the support column provided in the embodiment of the present application, the support column assembly 3 is split into a first connection column 31, a second connection column 32 and a first L-shaped column 33, wherein the first connection column 31 and the second connection column 32 can be pre-connected with the first wall 1 and the second wall 2 respectively, and the wall module formed by "wall + connection column" is used as the minimum transportation unit. This wall module is convenient for transportation as a plane structure, which reduces the difficulty of transportation. Moreover, during on-site construction, it is only necessary to connect the connecting column and the L-shaped column by means of bolts or other simple methods, without having to consider the connection construction between the wall and the connecting column (the above-mentioned wall module has already completed the connection between the wall and the connecting column in advance in the factory), thus ensuring on-site construction efficiency.

[0043] In an exemplary embodiment, the support column assembly 3 also includes a second L-shaped column 34 arranged at the notch of the L-shaped cavity 35, and the two ends of the second L-shaped column 34 are respectively fixed to the second end of the first connecting column 31 and the second end of the second connecting column 32, so that the first connecting column 31, the second connecting column 32, the first L-shaped column 33 and the second L-shaped column 34 are surrounded to form an L-shaped cavity 35 that is closed on all sides.

[0044] The second L-shaped column 34 may be a steel column.

[0045] The second L-shaped column 34 can be arranged together with the first connecting column 31, the second connecting column 32, and the first L-shaped column 33 to form an L-shaped cavity 35 that is closed on all sides. That is, the inner wall panels arranged on the inner side of the first wall and the inner side of the second wall no longer play the role of enclosing the L-shaped cavity 35, and the inner wall panels can be used as normal decorative panels.

[0046] It should be noted that Figures 1 to 5 It is directly shown that the support column assembly 3 includes a first connecting column 31, a second connecting column 32, a first L-shaped column 33 and a second L-shaped column 34. As mentioned above, the support column assembly 3 may only include the first connecting column 31, the second connecting column 32 and the first L-shaped column 33 (that is, the second L-shaped column 34 is not provided). It is only necessary to remove the second L-shaped column 34 during construction (the sizes of other components can be adaptively adjusted) and lay the interior wall panels normally.

[0047] In an exemplary embodiment, if Figure 5As shown, the first end of the first L-shaped column 33 is bent and extended along the thickness direction of the first wall 1 to form a first fixing portion 331, and the fixing member passes through the first fixing portion 331 and the first end of the first connecting column 31 to connect the first L-shaped column 33 and the first connecting column 31; the second end of the first L-shaped column 33 is bent and extended along the thickness direction of the second wall 2 to form a second fixing portion 332, and the fixing member passes through the second fixing portion 332 and the first end of the second connecting column 32 to connect the first L-shaped column 33 and the second connecting column 32.

[0048] The first end of the first L-shaped column 33 is bent to form a first fixing portion 331. A through hole is provided on the first fixing portion 331 so that a screw can be used to connect the first end of the first L-shaped column 33 to the first connecting column 31. A plurality of through holes can be provided on the first fixing portion 331 along the length direction (height direction) of the first L-shaped column 33 to improve the connection strength between the first L-shaped column 33 and the first connecting column 31.

[0049] Similarly, the second end of the first L-shaped column 33 is bent to form a second fixing portion 332, and a through hole is provided on the second fixing portion 332 so that a screw can connect the second end of the first L-shaped column 33 to the second connecting column 32. Along the length direction (height direction) of the first L-shaped column 33, a plurality of through holes can be provided on the second fixing portion 332 to improve the connection strength between the first L-shaped column 33 and the second connecting column 32.

[0050] In an exemplary embodiment, if Figure 1 and Figure 2 As shown, the first wall 1 includes a first wall body 11 and a first vertical purlin 12 located at the end of the first wall body 11, and the first vertical purlin 12 is welded and fixed to the first connecting column 31; the second wall 2 includes a second wall body 21 and a second vertical purlin 22 located at the end of the second wall body 21, and the second vertical purlin 22 is welded and fixed to the second connecting column 32.

[0051] The first wall 1 is connected and fixed to the first connecting column 31 by a first vertical keel 12 arranged at the side of the first wall 1. In other words, the first wall 1 is welded and fixed to the first connecting column 31. The second wall 2 is connected and fixed to the second connecting column 32 by a second vertical keel 22 arranged at the side of the second wall 2. In other words, the second wall 2 is welded and fixed to the second connecting column 32.

[0052] Of course, the first wall 1 may also include structures such as cross beams, top keels, and ground keels. The cross beams, top keels, and ground keels may also be welded and fixed to the first connecting column 31 .

[0053] It should be understood that “the first wall 1 and the first connecting column 31 ” and “the second wall 2 and the second connecting column 32 ” may also be fixed by bolt connection.

[0054] In an exemplary embodiment, if Figure 5 As shown, the second end of the first connecting column 31 extends in a direction parallel to the width of the first wall 1 and forms a first connecting portion 311, and the fixing member passes through the first connecting portion 311 and the second L-shaped column 34 to connect the first connecting column 31 and the second L-shaped column 34; the second end of the second connecting column 32 extends in a direction parallel to the width of the second wall 2 and forms a second connecting portion 321, and the fixing member passes through the second connecting portion 321 and the second L-shaped column 34 to connect the second connecting column 32 and the second L-shaped column 34.

[0055] In the embodiment of the present application, the first end of the first L-shaped column 33 is bent to form a first fixing portion 331, the second end of the first L-shaped column 33 is bent to form a second fixing portion 332, the second end of the first connecting column 31 is bent to form a first connecting portion 311, and the second end of the second connecting column 32 is completely formed into a second connecting portion 321, that is, fixing portions are provided at both ends of the first L-shaped column 33, and connecting portions are provided on the two connecting columns. In practical applications, the above structure can be appropriately adjusted, such as: fixing portions are provided at both ends of the first connecting column 31 to connect with the first L-shaped column 33 and the second L-shaped column 34 respectively, and fixing portions are provided at both ends of the second connecting column 32 to connect with the first L-shaped column 33 and the second L-shaped column 34 respectively, and then connected by fixing parts and spliced ​​to form a complete support column assembly 3.

[0056] The above-mentioned fixing members can be bolts, that is, the two ends of the first L-shaped column 33 are respectively fixed to the first end of the first connecting column 31 and the first end of the second connecting column 32 by bolts, and the two ends of the second L-shaped column 34 are respectively fixed to the second end of the first connecting column 31 and the second end of the second connecting column 32 by bolts.

[0057] In an exemplary embodiment, the width of the first fixing portion 331 is 1 / 3 to 1 / 2 of the thickness of the first wall, the width of the second fixing portion 332 is 1 / 3 to 1 / 2 of the thickness of the second wall, the width of the first connecting portion 311 is 1 / 3 to 1 / 2 of the thickness of the first wall, and the width of the second connecting portion 321 is 1 / 3 to 1 / 2 of the thickness of the second wall.

[0058] The width of the fixing part and the connecting part must ensure that the bolts can pass through and avoid cracking, but also avoid interference during assembly and high manufacturing costs due to the width being too long.

[0059] Specifically, the thickness of the first wall and the second wall may be 100 to 200 mm. The side lengths a and b of the first L-shaped column may be 250 to 350 mm, and the side lengths c and d of the second L-shaped column may be 150 to 250 mm. The width of the first fixing portion 331, the width of the second fixing portion 332, the width of the first connecting portion 311, and the width of the second connecting portion 321 may all be 50 mm.

[0060] In an exemplary embodiment, if Figure 4 As shown, the first L-shaped column 33 is arranged at the positive corner position where the first wall 1 and the second wall 2 are connected, and the second L-shaped column 34 is arranged at the negative corner position where the first wall 1 and the second wall 2 are connected.

[0061] The first L-shaped column 33 is an outer column at a corner position, that is, the first L-shaped column 33 is located at a positive angle position of the connection;

[0062] The second L-shaped column 34 is an inner column at the corner position, that is, the second L-shaped column 34 is located at the inner corner position of the connection. One end of the second L-shaped column 34 can be provided with multiple through holes along its length direction to facilitate bolt fixation with the first connection part 311; similarly, the other end of the second L-shaped column 34 can also be provided with multiple through holes along its length direction to facilitate bolt fixation with the second connection part 321.

[0064] The first connecting column 31 is provided with a first connecting hole, and the first wall 1 is connected to the L-shaped cavity 35 through the first connecting hole. During the manufacturing process of the first wall 1, both sides of the first wall 1 in the width direction are left empty, that is, when the first wall 1 is processed, the middle position thereof is filled with foamed concrete, and both sides of the first wall 1 in the width direction are empty areas, and the empty areas are connected to the L-shaped cavity 35 through the first connecting hole. After the connection between the wall and the supporting column is completed on site, concrete is poured into the L-shaped cavity 35 of the supporting column, and the concrete flows through the first connecting hole into the empty area of ​​the first wall 1, so that the first wall 1 and the supporting column assembly 3 are further connected through concrete, thereby improving the integrity of the first wall 1 and the supporting column assembly 3 and improving the connection reliability.

The connection between the wall and the support column is reliable and the on-site construction efficiency is high. The lower module transportation cost also reduces the overall construction cost of the prefabricated room module, which is conducive to the promotion of the prefabricated room module.

[0068] An embodiment of the present application further provides a building, comprising a plurality of the aforementioned prefabricated room modules, wherein the plurality of prefabricated room modules are vertically connected and / or horizontally connected.
