The multiple double-hole keels 1 include two first keels 3, multiple second keels 4, and multiple third keels 5. The two first keels 3 extend in a first direction and connect the upper floor slab (not shown) and the lower floor slab (not shown), respectively. The multiple second keels 4 extend in a second direction and are located between the two first keels 3. The multiple second keels 4 are spaced apart in the first direction. The third keels 5 extend in the first direction, with at least one third keel 5 located between two adjacent second keels 4. The first direction is perpendicular to the second direction. Each second keel 4 is provided with bidirectional clips 2 at both ends in the second direction for connecting to the first keel 3. Each third keel 5 is provided with bidirectional clips 2 at both ends in the first direction for connecting to the second keel 4. The multiple bidirectional clips 2 include a first clip 6 for connecting the first keel 3 and the second keel 4, as well as a second clip 7 and a third clip 8 located at both ends of the third keel 5 in the first direction. Any double-hole keel 1 includes a first base plate 9, two first side plates 10, and two flaps 11. The two ends of the first base plate 9 are respectively connected to the two first side plates 10. The ends of the two first side plates 10 away from the first base plate 9 are respectively connected to the two flaps 11. The two flaps 11 extend relative to each other at the ends away from the first side plates 10, and the double-hole keel 1 is surrounded by a C shape. The first base plate 9 is provided with a plurality of through-hole components 13. Each through-hole component 13 includes two trapezoidal holes 14 spaced apart along the length direction of the double-hole keel 1. Any two-way clamp 2 includes a second base plate 15, two parallel second side plates 16, and two bent plates 17. The two second side plates 16 are respectively connected to the two bent plates 17 at one end along the length direction of the second side plates 16, and the other ends are both connected to the second base plate 15. The ends of the bent plates 17 away from the second side plates 16 are bent toward the second base plate 15. The two second side plates 16 are provided with slots 20 at both ends along the width direction of the second side plates 16. The slot 20 of the first clamp 6 is correspondingly plugged into the flap 11 of the first keel 3, and the bent plate 17 of the first clamp 6 abuts against the end surface of the first base plate 9 of the flap 11 of the first keel 3 facing the first keel 3, so as to relatively limit the first keel 3 and the second keel 4 in the second direction and the third direction, wherein the third direction is perpendicular to the first and second directions.

The impact-resistant keel frame of the embodiment of the present application can be fixed without screws and can achieve high-impact resistant assembly. Moreover, the double-hole keel only requires conventional C-shaped keel openings, and no secondary opening and bending processing is required. The keel structure is simple, with few installation components and low overall cost. The two-way clips are easy to construct, and the engagement is firm, reliable, fast and efficient.

[0021] Figure 9 for Figure 1 In the second schematic diagram of the double hole keel, in some exemplary embodiments, as Figure 3 、 Figures 5 to 9 As shown, the double-hole keel 1 can be processed from a C-shaped light steel keel, and the plate thickness of the double-hole keel 1 can be h1. The first base plate 9 is perpendicular to the first side plate 10, and the flap 11 is perpendicular to the first side plate 10, so that the flap 11 is parallel to the first base plate 9. The extension direction of the double-hole keel 1 can be opposite to the length of the double-hole keel 1. For example, the length direction of the first keel 3 is consistent with the first direction, and for example, the length direction of the second keel 4 is consistent with the second direction. The second direction can be a vertical direction. The upper and lower floor plates can be spaced apart in the second direction, and the keel frame is vertically located in the space between the upper and lower floor plates. One end of the two first side plates 10 is respectively connected to the two ends of the first base plate 9 in the third direction. The two flaps 11 extend relative to each other, so that the first base plate 9, the two first side plates 10, and the two flaps 11 form a C shape. The double-hole keel 1 forms a first cavity 21 , and the double-hole keel 1 is open at both ends in its length direction to form an opening 22 . The space between the two flaps 11 forms an opening 12 , so that the first cavity 21 is open at the opening 22 and at the opening 12 .

[0022] In some exemplary embodiments, Figure 3 、 Figures 5 to 9 As shown, the distance between the flap 11 and the first bottom plate 9 can be L1, the distance between the two first side plates 10 can be L3, and the distance between the two flaps 11 can be L2. The distance between the two trapezoidal holes 14 in a through-hole assembly 13 can be L7. The distance between the edge of one trapezoidal hole 14 on one side of the length direction of the double-hole keel 1 and the edge of the other trapezoidal hole 14 on the same side of the length direction of the double-hole keel 1 can be L7.

[0023] In some exemplary embodiments, Figure 3 、 Figures 5 to 9As shown, the trapezoidal hole 14 is centrally arranged on the first base plate 9 in the third direction. The trapezoidal hole 14 may include a first through hole 23 and a second through hole 24 arranged sequentially and connected along the length of the double-hole keel 1. The size of the first through hole 23 in the third direction is larger than the size of the second through hole 24 in the third direction, that is, L4>L5. The trapezoidal hole 14 also includes a third through hole 25. The size of the third through hole 25 in the third direction is arranged to linearly increase from the second through hole 24 to the first through hole 23. The edges of the second through hole 24 at both ends in the third direction may be first edges 26, the edges of the third through hole 25 at both ends in the third direction may be second edges 27, and the edges of the first through hole 23 at both ends in the third direction may be third edges 28. The first edge 26 and the third edge 28 are both arranged along the length of the double-hole keel 1, while the second edge 27 is arranged at an angle. The two edges of the third through hole 25 in the third direction (ie, the second edges 27 ) can guide the edge of the second through hole 24 in the third direction (ie, the first edge 26 ) to slide into the slot 20 of the third clamping member 8 .

[0024] In some exemplary embodiments, Figure 3 、 Figures 5 to 9 As shown, when the first keel 3 is installed, the first base plate 9 of the first keel 3 can be fixed to the upper and lower floor slabs using expansion bolts. The opening 12 of the first keel 3 fixed to the upper floor slab faces the lower floor slab, and the opening 12 of the first keel 3 fixed to the lower floor slab faces the upper floor slab, so that the openings 12 of the two first keels 3 are opposite each other. When the second keel 4 is installed, all the openings 12 of the second keel 4 face the same side in the first direction, and the two openings 22 of each second keel 4 correspond to two first keels 3 respectively. At the same time, the first through hole 23 of the trapezoidal hole 14 on the second keel 4 is located on the side of the second through hole 24 closer to the upper floor slab. When the third keel 5 is installed, all the openings 12 of the third keel 5 face the lower floor slab, and the two openings 22 of each third keel 5 correspond to two adjacent second keels 4 respectively. The opposite end surfaces of the two first side panels 10 of the first keel 3, the second keel 4 and the third keel 5 are flush with each other, so that the wall panels fixed on the keel frame can be attached to the flat end surfaces, which is beneficial to the installation aesthetics of the wall panels.

[0025] Figure 10 for Figure 2 The second schematic diagram of the bidirectional card in Figure 11 for Figure 2 In the third schematic diagram of the bidirectional card, in some exemplary embodiments, as Figure 4 、 Figure 10 and Figure 11As shown, the bidirectional clamp 2 can be formed by cutting and bending a metal plate. The second base plate 15 of the bidirectional clamp 2 is perpendicular to the second side plate 16. The two second side plates 16 are parallel. The length direction of the second side plates 16 is perpendicular to the second base plate 15, and the width direction of the second side plates 16 is consistent with the third direction. The two bent plates 17 are located on the same side of the two second side plates 16 in a direction perpendicular to the second side plates 16. The angle between the bent plates 17 and the second side plates 16 can be α, and the value of α can be 3° to 15°.

[0026] In some exemplary embodiments, Figure 4 、 Figure 10 and Figure 11 As shown, the second side panel 16 may include a main panel 18 and an extension panel 19 arranged in sequence along the length of the second side panel 16 (perpendicular to the second base panel 15). The main panel 18 is located on the side of the extension panel 19 that is closest to the second base panel 15. The bent panel 17 connects the end of the extension panel 19 that is distal to the main panel 18. Two slots 20 are located between the main panel 18 and the extension panel 19, extending along the third direction. The main panel 18 is centered on the extension panel 19 in the third direction.

[0027] In some exemplary embodiments, Figure 4 、 Figure 10 and Figure 11As shown, the dimensions of the second base plate 15 and the main plate 18 in the width direction (second direction) of the second side plate 16 may both be L8; the dimension of the extension plate 19 in the width direction (second direction) of the second side plate 16 may be L9; the dimension of the two slots 20 in the width direction (second direction) of the second side plate 16 may be L10; the distance between the end faces of the two second side plates 16 facing each other may be L11; the dimension of the two-way clip in the direction perpendicular to the second side plate 16 may be L12; the dimension of the bent plate 17 in the direction perpendicular to the second side plate 16 may be L13; the groove width of the slot 20 may be the dimension of the slot 20 in the length direction of the second side plate 16 (i.e., L14); the distance between the bent plate 17 and the main plate 18 in the length direction of the second side plate 16 may be L15; the distance between the end faces of the two second side plates 16 on the same side perpendicular to the direction of the second side plate 16 may be L16. The dimension of the main plate 18 in the width direction (second direction) of the second side plate 16 may be equal to the distance (L3) between the two first side plates 10 of the double-hole keel 1, that is, L8=L3; the distance between the opposite end surfaces of the two second side plates 16 may be equal to the distance between the flap 11 and the first bottom plate 9, that is, L11=L1, so that the two-way clip at one end where the two second side plates connect to the second bottom plate 15 can be inserted into the first cavity 21 enclosed by the double-hole keel 1 through the opening 22 of the double-hole keel 1. Specifically, one second side plate 16 of the two-way clip can fit in contact with the first bottom plate 9 of the double-hole keel 1, and the other second side plate 16 of the two-way clip can fit in contact with the flap 11. The two second side plates 16 at their ends in the width direction can respectively rest against the two first side plates 10 of the double-hole keel 1, thereby limiting the relative position of the two-way clip and the double-hole keel in the second direction and perpendicular to the first bottom plate 9. The dimension (i.e., L9) of the extension plate 19 in the width direction (second direction) of the second side plate 16 is smaller than the dimension (L8) of the main plate 18 in the width direction (second direction) of the second side plate 16 and is larger than the distance (L2) between the two flaps 11 of the double-hole keel 1. The minimum distance (L10) between the two slots 20 can be equal to the minimum distance (L2) between the two flaps 11 and equal to the distance (L5) between the two edges (i.e., first edges 26) of the second through-hole 24 in the third direction. The dimension (L6) of the first through-hole 23 in the longitudinal direction of the double-hole keel 1 can be larger than the maximum distance (L13) of the bent plate 17 in a direction perpendicular to the second side plate 16, allowing the extension plate and the bent plate 17 to pass through the trapezoidal hole 14 through the first through-hole 23. The dimension (i.e., L12) of the bidirectional clip 2 in a direction perpendicular to the second side plate 16 is smaller than the distance (L2) between the two flaps 11 of the double-hole keel 1. The distance between the two trapezoidal holes 14 of a through hole component 13 in the length direction of the double-hole keel 1 (ie L7) is equal to the distance between the two second side plates 16 of the two-way clamp 2 in the direction perpendicular to the second side plates 16 (ie L16).The dimension of the first through hole 23 in the third direction (i.e., L4) is larger than the dimension of the extension plate 19 in the width direction (second direction) of the second side plate 16 (i.e., L9), and the dimension of the second through hole 24 in the third direction (i.e., L5) may be smaller than the dimension of the extension plate 19 in the width direction (second direction) of the second side plate 16 (i.e., L9), i.e., L9>L5.

[0028] Figure 12 This is a schematic diagram of the connection between the first keel and the first clamp of this exemplary embodiment. Figure 13 for Figure 1 The third connection diagram of the first keel and the second keel, Figure 14 is a schematic diagram of the installation of the first clamp of this exemplary embodiment. In some exemplary embodiments, as Figure 5 、 Figure 6 、 Figures 12 to 14 As shown, when the second keel and the first clamp are connected, the main board 18 and the second bottom plate 15 of the first clamp can be located in the first cavity 21 surrounded by the second keel 4, and the main board 18 and the second bottom plate 15 of the first clamp 6 can be inserted into the first cavity 21 through the opening 22 of the second keel 4, wherein one second side plate 16 of the first clamp 6 can fit into the first bottom plate 9 of the second keel 4, and the other second side plate 16 of the first clamp 6 can fit into the flap 11 of the second keel 4. The two second side plates 16 can respectively abut against the two first side plates 10 of the second keel 4 at both ends in the second direction, thereby relative limiting the first clamp 6 and the second keel 4 in the first and third directions. The main board 18 of the second keel 4 extends into the first cavity 21 at one end away from the extension plate 19, so that the extension plate 19 and the bent plate 17 are outside the first cavity 21 surrounded by the second keel 4. When the first keel 3 and the first clamp 6 are connected, the extension plate 19 and the bent plate 17 of the first clamp 6 can be located in the first cavity 21 enclosed by the first keel 3, the second side plate of the first clamp 6 is perpendicular to the first direction, and the two flaps 11 of the first keel 3 can be correspondingly inserted into the two slots 20 of the first clamp 6. At the same time, the end of the bent plate 17 close to the second bottom plate can abut against the end surface of the flap 11 of the first keel 3 facing the first bottom plate 9 of the first keel 3, thereby relative limiting the first clamp 6 and the first keel 3 in the second and third directions. Thus, the first keel 3 and the second keel 4 can be limited in the second and third directions by the first clamp 6, and the first keel 3 and the second keel 4 can slide relative to each other in the first direction to adjust their positions. During the installation of the first keel 3 and the first clamp 6, in order to facilitate the first clamp 6 to extend into the first keel 3, the second side panel 16 can be kept nearly parallel to the first side panel 10, and the extension plate 19 and the bent plate 17 are extended into the first cavity 21 surrounded by the first keel 3. Then, the first clamp is rotated so that the second side panel 16 is perpendicular to the first side panel 10. During the rotation process, the two flaps 11 of the first keel 3 are inserted into the two slots 20 of the first clamp 6.

[0029] Figure 15 for Figure 1 Schematic diagram of the connection between the third keel and the two-way clamp, in some exemplary embodiments, such as Figure 7 and Figure 15 As shown, when the third keel and the bidirectional clip are connected, the bidirectional clip located at one end of the third keel in the first direction can be the second clip, and the other end can be the third clip. The main board 18 and the second bottom plate 15 of the bidirectional clip can be located in the first cavity 21 surrounded by the third keel 5. The main board 18 and the second bottom plate 15 of the bidirectional clip can be inserted into the first cavity 21 through the opening 22 of the third keel 5. Among them, one second side plate 16 of the bidirectional clip can fit the first bottom plate 9 of the third keel 5, and the other second side plate 16 of the bidirectional clip can fit the flap 11 of the third keel 5. The two second side plates 16 can respectively rest on the two first side plates 10 of the third keel 5 at both ends of the second direction, thereby relative limiting the bidirectional clip and the third keel 5 in the second and third directions. The main board 18 of the third keel 5 extends into the first cavity 21 away from the end of the extension plate 19, so that the extension plate 19 and the bent plate 17 are outside the first cavity 21 surrounded by the third keel 5. The second side plates 16 on the bidirectional clamps are all perpendicular to the second direction, and the bent plates 17 are all located on the side of the second side plates 16 connected thereto close to the lower floor slab.

[0030] In some exemplary embodiments, Figure 7 and Figure 15 As shown, when the first keel 3 and the second clamp 6 are connected, the extension plate 19 and the bent plate 17 of the second clamp 6 can be located in the first cavity 21 surrounded by the second keel 4, the second side plate of the second clamp 6 is perpendicular to the second direction, and the two flaps 11 of the second keel 4 can be correspondingly plugged into the two slots 20 of the second clamp 6. At the same time, the end of the bent plate 17 close to the second bottom plate can abut against the end surface of the flap 11 of the second keel 4 facing the first bottom plate 9 of the second keel 4, thereby relative limiting the second clamp 6 and the second keel 4 in the first, second, and third directions. Thus, the second keel 4 and the third keel 5 can be limited in the second and third directions by the second clamp 6. During the installation of the second keel 4 and the second clamp 6, in order to facilitate the insertion of the second clamp 6 into the second keel 4, the second side panel 16 can be kept nearly parallel to the first side panel 10, and the extension panel 19 and the bent panel 17 can be inserted into the first cavity 21 enclosed by the second keel 4. The second clamp can then be rotated so that the second side panel 16 is perpendicular to the first side panel 10. During the rotation process, the two flaps 11 of the second keel 4 are inserted into the two slots 20 of the second clamp 6. However, the present invention is not limited to this. Alternatively, the extension panel 19 and the bent panel 17 can be directly inserted into the first cavity 21 enclosed by the second keel 4 under the action of external force.

[0031] Figure 16 for Figure 2The third connection diagram of the two-way clamp and the second keel, Figure 17 is a first installation diagram of the third clamp of this exemplary embodiment, Figure 18 is a second installation diagram of the third clamp of this exemplary embodiment. In some exemplary embodiments, as shown in FIG. Figure 8 、 Figures 16 to 18 As shown, the two second side panels of the third clamp 8 can be plugged into the corresponding two trapezoidal holes 14, and the extension plate 19 and the bent plate 17 of the second side panel can extend into the first cavity 21 of the second keel 4 through the trapezoidal holes 14. The two slots 20 of the third clamp 8 are plugged into the two edges of the second through hole 24 in the third direction (i.e., the first edge 26), and the edge of the second through hole 24 close to the lower floor can support the second side panel 16. Among them, the two edges of the second through hole 24 in the third direction (i.e., the first edge 26) are against the two ends of the second side panel 16 in the third direction, forming a limit. As a result, the third keel 5 is connected to the adjacent second keels 4 at the second clamp 7 and the third clamp 8 respectively, stabilizing the adjacent second keels 4, providing effective support, and improving impact resistance.

[0032] In some exemplary embodiments, Figure 8 、 Figures 16 to 18 As shown, during the installation of the third clamp 8 and the second keel 4, the second side plate 16 of the third clamp 8 is first aligned with the first through-hole 23, and the extension plate 19 and the bent plate 17 are passed through the first through-hole 23 until the main plate 18 rests on the first bottom plate 9 of the second keel 4. Subsequently, the third clamp 8 is lowered, and the second side plate 16 of the third clamp 8 passes through the third through-hole 25 and reaches the second through-hole 24, forming a slot 20 that is correspondingly plugged into the edge of the second through-hole 24 in the third direction (the first edge 26).

[0033] In some exemplary embodiments, a method for installing an impact-resistant keel frame, applied to the above-mentioned impact-resistant keel frame, includes: Step S1 , installing double-hole keels 1 on the upper floor and the lower floor respectively to form two first keels 3 , wherein the first bottom plates of the two first keels 3 are connected to the upper floor and the lower floor respectively, and the openings of the two first keels 3 are opposite to each other.

[0034] Step S2: Install multiple second keels 4. Take another double-hole keel 1 and install two-way clips 2 at both ends of the double-hole keel 1. Connect the two-way clips 2 to two first keels 3. The double-hole keel 1 is used as the second keel 4, and two-way clips 2 are installed at both ends of the second keel 4. The two-way clips 2 installed in this step are first clips 6, which can be plugged into the open end of the second keel 4. Then, place the second keel 4 with the first clips 6 between the two first keels 3, tilt it, and rotate it to snap the first clips 6 into the first keels 3. During the connection process between the first clamp 6 and the first keel 3, the second side plate 16 of the first clamp 6 can be kept nearly parallel to the first side plate 10 of the first keel 3, and the extension plate 19 and the bent plate 17 of the first clamp 6 can be extended into the first cavity 21 surrounded by the first keel 3. Then, the first clamp 6 and the second keel 4 are rotated as a whole so that the second side plate 16 of the first clamp 6 is perpendicular to the first side plate 10. During the rotation process, the two flaps 11 of the first keel 3 are inserted into the two slots 20 of the first clamp 6 to form a limit. In this way, multiple second keels 4 are installed between two first keels 3, and the spacing of the second keels 4 in the first direction can be adjusted, and can be adjusted according to the third keel 5 in step S3.

[0035] Step S3, install the third keel 5, then take the double-hole keel 1, and install the two-way clips 2 at both ends of the double-hole keel 1, and connect the two-way clips 2 to two adjacent second keels 4 respectively. Among them, take the double-hole keel 1 as the third keel 5, and install the two-way clips 2 at both ends of the third keel 5. The two-way clips 2 installed in this step are the second clip 7 and the third clip 8, and the second clip 7 and the third clip 8 can be plugged into the open end of the third keel 5. Subsequently, the third keel 5 is placed between the two second keels 4 and tilted, and the second clip 7 is rotated to snap into one of the second keels 4. The connection process of the second clip 7 and the second keel 4 can realize the insertion of the two flaps 11 of the second keel 4 into the two slots 20 of the second clip 7 to form a limit. Then, the third clip 8 is snapped into the through-hole component of another second keel 4. First, align the second side plate 16 of the third clamp 8 with the first through-hole 23. Insert the extension plate 19 and the bent plate 17 through the first through-hole 23 until the main plate 18 rests against the first base plate 9 of the second keel 4. Then, lower the third clamp 8, and the second side plate 16 of the third clamp 8 passes through the third through-hole 25 and reaches the second through-hole 24, forming a slot 20 that mates with the edge of the second through-hole 24 in the third direction (the first edge 26). This forms the connection between the third keel 5 and the second keel 4. After completing the above steps, install all the third keels 5 to complete the keel frame installation.
