The first through hole 10 can be formed by opening the first bottom plate 7. The first through hole 10 can be a rectangular hole. The dimension of the first through hole 10 in the second direction can be L1, and the dimension of the first through hole 10 in the vertical direction can be L2. The first through hole 10 is centered on the first bottom plate 7 in the second direction. The distance between the hole wall of the first through hole 10 in the second direction and the adjacent first side plate 8 can be L6.

[0022] In some exemplary embodiments, Figure 3 and Figure 6As shown, the first bottom plate 7, first side plate 8, and first folding plate 9 are all flat plates. The first bottom plate 7 is perpendicular to the first side plate 8, the first folding plate 9 is perpendicular to the first side plate 8, the first bottom plate 7 is parallel to the first folding plate 9, and the two first side plates 8 are parallel. The thickness of the vertical purlin 3 can be h, that is, the thickness of the first bottom plate 7, first side plate 8, and first folding plate 9 are all h. The spacing between the two first side plates 8 in the second direction can be L4, the dimension of the vertical purlin 3 in the second direction can be L5, the spacing between the two first folding plates 9 in the second direction can be L3, the extension length of the first folding plate 9 in the second direction can be L7, and the spacing between the first folding plate 9 and the first bottom plate 7 in the first direction can be L8.

Therefore, the dimension of the opening 11 in the second direction is equal to the dimension of the first through hole 10 in the second direction.

[0023] Figure 7 for Figure 2 The second schematic diagram of the connector in Figure 8 for Figure 2 The third schematic diagram of the connector in Figure 9 for Figure 2 In a fourth schematic diagram of a connector, in some exemplary embodiments, as Figure 4 、 Figures 7 to 9 As shown, the second base plate 13 includes two side plates 18 and a middle plate 17. The two side plates 18 are spaced apart in the width direction of the second base plate 13, and the middle plate 17 is sandwiched between the two side plates 18, so that the middle plate 17 is centered in the width direction of the second base plate 13. The middle plates 17 can be curved plates, forming a convex hull 16. The side plates 18 can be flat plates. The width direction of the second base plate 13 will be referred to as the width direction, the length direction of the second base plate 13 will be referred to as the length direction, and the thickness direction of the second base plate 13 will be referred to as the thickness direction.

[0024] In some exemplary embodiments, Figure 4 、 Figures 7 to 9As shown, the lengthwise dimension of the middle panel 17 in the second direction (i.e., the second direction) can be L9, and the maximum lengthwise dimension of the side panels 18 in the second direction (i.e., the second direction) can be L10, where L9>L10. The ends of the middle panel 17 in the second direction (i.e., the second direction) respectively protrude beyond the ends of the side panels 18 in the second direction. The middle panel 17 comprises a curved panel body 23 and two clips 24. Both the curved panel body 23 and the clips 24 have arc-shaped cross-sections. The curved panel body 23 connects the two side panels 18, and the clips 24 are located at the ends of the curved panel body 23 in the second direction. The lengthwise dimension of the curved panel body 23 in the second direction (i.e., the second direction) can be aligned with the maximum lengthwise dimension of the side panels 18 in the second direction. The portion of the middle panel 17 that protrudes beyond the side panels 18 in the second direction (i.e., the second direction) can serve as the clips 24. The size (L9) of the middle plate 17 in the length direction (i.e., the second direction) may be larger than the size (L1) of the first through hole 10 in the second direction, and larger than the distance (L3) between the two first folding plates 9 in the second direction, i.e., L9>L1=L3; moreover, the size (L9) of the middle plate 17 in the length direction (i.e., the second direction) is equal to the distance (L4) between the two first side plates 8 in the second direction, i.e., L9=L4.

[0025] In some exemplary embodiments, Figure 4 、 Figures 7 to 9 As shown, the dimension of the side panel 18 in the longitudinal direction (i.e., the second direction) can be L11, and the maximum dimension of the side panel 18 in the longitudinal direction (i.e., the second direction) can be the dimension of the end of the side panel 18 connected to the arc plate body 23 (i.e., L10). The dimension (L11) of the side panel 18 in the longitudinal direction (i.e., the second direction) can decrease linearly as it moves away from the middle panel 17, so that the side panel 18 can be a trapezoidal plate. The side panel 18 forms inclined first inclined surfaces 25 at both ends of the longitudinal direction (i.e., the second direction). The maximum dimension (L10) of the side panel 18 in the longitudinal direction (i.e., the second direction) can be equal to the dimension (L1) of the first through hole 10 in the second direction, or can be equal to the distance (L3) between the two first folded plates 9 in the second direction, where L10 = L1 = L3.

[0026] In some exemplary embodiments, Figure 4 、 Figures 7 to 9 As shown, the dimension of the card plate 24 in the width direction of the second base plate 13 can be L12, wherein the dimension (L12) of the card plate 24 in the width direction of the second base plate 13 can be linearly reduced along the length direction (i.e., the second direction) away from the side of the arc plate body 23, so that the card plate 24 is wider at the end connected to the arc plate body 23 and narrower at the end away from the arc plate body 23, so as to facilitate the second base plate to pass through the first through hole.

[0027] In some exemplary embodiments, Figure 4 、 Figures 7 to 9As shown, the second side panel 14 includes a main panel 19 and two bent panels 20, respectively, disposed at both ends of the second side panel 14 in the length direction (i.e., the second direction). The main panel 19 is connected to the second bottom panel 13 at one end in the thickness direction. The main panel 19 is perpendicular to the side panels 18 of the second bottom panel 13. The main panel 19 may have a dimension L13 in the length direction (i.e., the second direction). The dimension of the main panel 19 in the length direction (i.e., the second direction) is smaller than the dimension (L1) of the first through hole 10 in the second direction and smaller than the spacing (L3) between the two first folded panels 9 in the second direction. L13 < L1 = L3.

[0028] In some exemplary embodiments, Figure 4 、 Figures 7 to 9 As shown, the bent plate 20 may include an extension plate 21 and a vertical plate 22. The extension plate 21 is connected to the main plate 19 at one end in the longitudinal direction (i.e., the second direction) and to one end of the vertical plate 22 at the other end. The other end of the vertical plate 22 extends toward the width of the second bottom plate 13, close to the second bottom plate 13. The vertical plate 22 is perpendicular to the extension plate 21. The main plate 19 and the extension plate 21 are coplanar. The bent plate 20 may be spaced apart from the middle plate 17 in the thickness direction. The minimum distance between the bent plate 20 and the middle plate 17 in the thickness direction (L15) may be equal to the plate thickness (i.e., h) of the vertical keel. The end surface of the bent plate 20 near the second bottom plate 13 forms the abutment portion 15.

[0029] In some exemplary embodiments, Figure 4 、 Figures 7 to 9 As shown, the maximum spacing between the two bent plates 20 in the longitudinal direction (i.e., the second direction) can be L14, that is, the distance between the opposing end surfaces of the vertical plates 22 of the two bent plates 20 can be L14. The maximum spacing between the two bent plates 20 in the longitudinal direction (i.e., the second direction) (i.e., L14) can be equal to the distance between the two first side plates 8 of the vertical keel 3 (i.e., L4), that is, L4 = L14. The maximum distance between the opposing end surfaces of the two second side plates 14 can be L16, that is, the distance between the opposing end surfaces of the main plates 19 of the two second side plates 14 is L16. The maximum distance between the opposing end surfaces of the two second side plates 14 (L16) can be less than the spacing (L8) between the first folding plate 9 and the first bottom plate 7 in the first direction, that is, L16 < L8.

[0030] Figure 10 for Figure 2 Schematic diagram of the transverse keel in Figure 11 for Figure 2 Schematic diagram of the installation of the transverse keel and the connecting member, in some exemplary embodiments, such as Figure 10 and Figure 11As shown, the cross-sections of the transverse keel 4 and the vertical keel 3 are identical, i.e., the cross-section of the transverse keel 4 taken perpendicular to its extension direction is C-shaped. The transverse keel 4 extends along a first direction and may include a third base plate 26, two third side plates 27, and two third folding plates 29. The two third side plates 27 are connected to the ends of the third base plate 26 in the second direction at one end in the vertical direction, and extend to the same side in the vertical direction and are connected to the two third folding plates 29 at the other ends. The two third folding plates 29 extend relative to each other, forming a C-shape. The transverse keel 4 encloses a second cavity 29. The transverse keel 4 is open at both ends in the first direction, forming a second opening 32. The spacing between the two third side plates 27 in the second direction may be L17, where L17 = L4.

[0031] In some exemplary embodiments, Figure 10 and Figure 11 As shown, the two ends of the transverse keel 4 in the first direction can be connected to two connecting members 6, respectively. One end of the second side plate 14 of the two connecting members 6 can be inserted into the second cavity 29 surrounded by the transverse keel 4 through the second opening 32, while the other end extends out of the second cavity 29. The second bottom plate 13 is located outside the transverse keel 4. The connecting members at both ends of the transverse keel 4 in the first direction are divided into a first connecting member 30 and a second connecting member 31. The first connecting member 30 can be fastened to the first through hole of one vertical keel 3, while the second connecting member 31 can be fastened to the first folded plate of another adjacent vertical keel 3.

[0032] Figure 12 for Figure 2 The second installation diagram of the vertical keel and the connecting parts, Figure 13 for Figure 2 In the third installation diagram of the vertical keel and the connecting member, in some exemplary embodiments, as shown in FIG. Figure 5 、 Figure 12 and Figure 13As shown, one end of the second side panel 14 of the first connector 30 passes through the first through-hole 10 of the vertical purlin 3 and extends into the first cavity 12 enclosed by the vertical purlin 3. The second bottom panel 13 is located within the first cavity 12. The two ends of the protrusion 16 respectively abut the two first side panels 8 to limit the first connector 30 in the second direction. The width direction of the second bottom panel is consistent with the first direction. Moreover, the protrusion 16 can abut against the end surface of the first bottom panel 7 facing the first folding plate 9 and against the surface of the first bottom panel 7 located between the first through-hole 10 and the first side panel 8. The abutment portion 15 on the second side panel 14 abuts against the end surface of the first bottom panel 7 facing away from the first folding plate 9. Thus, the abutment portion 15 on the second side panel 14 can clamp the first bottom panel 7 with the protrusion 16 to limit the first connector 30 and the vertical purlin 3 in the first direction. When connecting the first connecting member 30 and the vertical keel 3, the first connecting member 30 can be tilted, and the length direction of the second base plate can be diagonal to the first through hole 10. First, one end of the convex bump 16 is inserted into the first cavity 12, and then the first base plate is rotated to be turned into the first cavity 12.

[0033] In some exemplary embodiments, Figure 5 、 Figure 12 and Figure 13 As shown, one end of the second side panel 14 of the second connector 31 extends through the opening 11 of the vertical purlin 3 and into the first cavity 12 formed by the vertical purlin 3. The second bottom panel 13 is located within the first cavity 12. The two ends of the protrusion 16 abut the two first side panels 8, respectively, to restrain the second connector 31 in the second direction. The width of the second bottom panel 8 aligns with the first direction. Furthermore, the protrusion 16 can abut against the end surface of the first folding plate 9 facing the first bottom panel 7. The abutment 15 on the second side panel 14 abuts against the end surface of the first folding plate 9 facing away from the first bottom panel 7. Thus, the abutment 15 on the second side panel 14 and the protrusion 16 can clamp the first folding plate 9, restraining the second connector 31 and the vertical purlin 3 in the first direction. When connecting the second connector 31 to the vertical purlin 3, the second connector 31 can be tilted to facilitate its insertion into the first cavity 12.

Figures 6 to 9 ,as well as Figure 14 As shown, the vertical purlins 3 extending in the vertical direction are open at both ends, forming first openings 33. Connectors 6 may be provided at both ends of the vertical purlins 3. The width of the second bottom plate 13 of the connector 6 may align with the first direction. One end of the second side plate 14 of the connector 6 may be inserted into the first cavity 12 formed by the vertical purlins 3 through the first opening 33, while the other end extends out of the first cavity 12. The second bottom plate 13 is positioned outside the vertical purlins 3.

Both extend in the first direction and connect the upper floor slab 1 and the lower floor slab 2, respectively. The floor keels 5 have the same cross-section as the vertical keels 3; that is, the cross-section of the floor keels 5 taken perpendicular to their extension direction is C-shaped. The floor keels 5 extend in the first direction and may include a fourth base plate 34, two fourth side plates 35, and two fourth folding plates 36. The two fourth side plates 35 have one vertical end connected to the second ends of the fourth base plate 34, respectively.

The floor keels 5 enclose a third cavity 38, with an opening 39 formed between the two fourth folding plates 36. The spacing between the two fourth side plates 35 in the second direction may be L18, where L18 = L17 = L4. The distance between the two fourth folding plates 36 may be L19, where L19 = L3 = L1.

Figures 14 to 17 As shown, the vertical purlins 3 are provided with connectors 6 at both ends in the vertical direction, connecting to the floor purlins 5 via these connectors. The fourth bottom plate 34 of the floor purlins 5 can be aligned with the upper and lower floor slabs and connected via expansion bolts, with the openings of the two floor purlins 5 facing each other. The connection between the connector 6 and the floor purlins 5 can be similar to the connection between the second connector and the vertical purlins. In the portion of the connector 6 outside the vertical purlin 3, one end of the second side plate 14 of the connector 6 extends through the opening 39 of the floor purlin 5 and into the third cavity 38 formed by the floor purlin 5. The second bottom plate 13 of the connector 6 is located within the third cavity 38. The ends of the protrusion 16 abut against the two fourth side plates 35, respectively, to restrain the connector 6 in the second direction. The width of the second bottom plate aligns with the first direction. Furthermore, the protrusion 16 can abut against the end surface of the fourth folded plate 36 facing the fourth bottom plate 34. The abutment portion 15 on the second side plate 14 abuts against the end surface of the fourth folded plate 36 facing away from the fourth bottom plate 34. Thus, the abutting portion 15 on the second side plate 14 can clamp the fourth bottom plate 34 together with the convex bump 16 to limit the connecting member 6 and the vertical keel 3 in the vertical direction.

[0037] In some exemplary embodiments, Figures 2 to 17As shown, the end surface of the vertical keel 3 in the second direction can be the end surface of the two first side panels facing each other, that is, the first end surface 40; the end surface of the transverse keel 4 in the second direction can be the end surface of the two third side panels facing each other, that is, the second end surface 41; and the end surface of the ceiling keel 5 in the second direction can be the end surface of the two fourth side panels facing each other, that is, the third end surface 42. The end surfaces of the vertical keel 3 in the second direction, the end surfaces of the transverse keel 4 in the second direction, and the end surfaces of the ceiling keel 5 in the second direction are flush with each other. For example, the two end surfaces of the vertical keel 3 in the second direction can be flush with the two end surfaces of the transverse keel 4 in the second direction.

[0039] In step S2, multiple vertical purlins 3 are installed. Connectors 6 are installed at both ends of the vertical purlins 3. The connectors 6 installed in this step can be plugged into the first openings of the vertical purlins 3. Subsequently, the vertical purlin 3 with the connectors 6 is placed between two ceiling purlins 5 and tilted. The connectors 6 are rotated so that the protrusions of the connectors 6 engage with the ceiling purlins 5. In this way, multiple vertical purlins 3 are installed between the two ceiling purlins 5, and the spacing between the vertical purlins 3 in the first direction is adjustable.

[0040] Step S3, install the transverse keel 4, install connectors 6 at both ends of the transverse keel 4, and connect the connectors 6 to two adjacent vertical keels 3 respectively. Among them, the connectors 6 are installed at both ends of the transverse keel 4. The connectors 6 installed in this step are the first connector and the second connector, which can be plugged into the second open port of the transverse keel 4. Subsequently, the transverse keel 4 is placed between the two vertical keels 3 and tilted, and the first connector is inserted into the first through hole of one vertical keel 3. Then, the second connector is inserted into the first folding plate of the other vertical keel 3. In this way, the connection between the transverse keel 4 and the vertical keel 3 is formed. After completing the above steps and installing all transverse keels 4, the installation of the keel assembly system is completed.
