[0032] Please refer to Figures 1 to 5 , the present utility model provides a sill support assembly, including: a bracket 1, a support member 2, and an external connection member 3. Specifically, the upper part of the bracket 1 is used for fixedly connecting with the external sill 15, so as to realize the support of the external sill 15. Specifically, please refer to Figure 5 . The support member 2 supports on the bracket 1 to enhance the structural strength of the bracket 1, thereby improving the support capacity of the bracket 1 for the external sill 15. The external connection member 3 is connected to the support member 2 or the bracket 1 and at the same time connects to an external load-bearing object, so as to provide support for the bracket 1 and the support member 2 and further improve the support strength of the bracket 1. The external load-bearing object can be, for example, a load-bearing wall in an elevator shaft.

[0033] Exemplarily, please refer to Figure 4 , a plurality of fixing holes 11 may be provided in the upper part of the bracket 1, and the bracket 1 can be fixedly connected to the external sill through the fixing holes 11. Specifically, the fixing holes 11 in the upper part of the bracket 1 correspond to the fixing holes (not shown in the figure) on the external sill. Bolts can be passed through the fixing holes of both from one side and then nuts can be installed from the other side, so as to fixedly connect the bracket 1 and the external sill to each other. In other cases, the bracket 1 and the external sill can also be fixedly connected in other ways, which are not specifically limited herein.

[0034] Please refer to Figure 2, the specific way for the support member 2 of the present utility model to support the bracket 1 is that the support member 2 is connected to the lower part of the bracket 1. A part of the support member 2 abuts and supports against the lower part of the bracket 1, and a part of the support member 2 is inserted into the bracket 1 from bottom to top and abuts and supports against the upper part of the bracket 1. Optionally, the support member 2 can be fixedly connected to the bracket 1 or slidably connected to the bracket 2, so that the support member 2 can move along the length direction of the bracket 1. By supporting both the lower part and the upper part of the bracket 1 with the support member 2, the structural strength of the bracket 1 of the present utility model is higher than that of the traditional bracket, and it has stronger bearing capacity and reliability. Exemplarily, the support member 2 and the bracket 1 can be fixedly connected by welding, making the connection between the two more firm and the supporting effect of the support member 2 on the bracket 1 stronger.

[0035] In a specific embodiment, please refer to Figures 2 to 4 , the lower part of the bracket 1 has a notch 12, and the support member 2 includes a bottom plate 21 and a vertical plate 22. Specifically, the bottom plate 21 is fixedly connected (such as welded) and supported on the lower side of the edge of the notch 12. One side of the vertical plate 22 is fixedly connected to the bottom plate 21, and the other side is inserted into the bracket 1 through the notch 12 and abuts and supports against the upper part of the bracket 1.

[0036] In this embodiment, exemplarily, the bracket 1 can be in a long strip structure adapted to the external sill, and the length of the bracket 1 can be adaptively adjusted according to the length of the external sill, which is not specifically limited herein. The cross-section of the bracket 1 is in a shape similar to a "U", and the two ends of the cross-section of the bracket 1 are turned inwards. The part where the bracket 1 is turned inwards is defined as the folding part 13, and the notch 12 is formed between the two folding parts 13, and the folding part 13 is the edge of the notch 12. The bottom plate 21 abuts against the lower sides of the two folding parts 13, and welding can be performed between the bottom plate 21 and the lower sides of the folding parts 13, so that the bottom plate 21 has a good supporting effect on the lower part of the bracket 1. One side of the vertical plate 22 can be connected to the bottom plate 21 by welding or integrally formed, for example Figure 3 as shown in , the vertical plate 22 is connected to the edge of the bottom plate 21 and is integrally formed with the bottom plate 21, similar to turning up one side of the bottom plate 21 to form the vertical plate 22. The side of the vertical plate 22 away from the bottom plate 21 is inserted into the bracket 1 through the notch 12 and abuts and supports against the upper part of the bracket 1 to support the upper part of the bracket 1. The insertion described in this embodiment means that there is a certain space inside the bracket 1, such as the space of a structure similar to a "U" shape. The vertical plate 22 can pass through this space and finally abut and support against the upper part of the bracket 1, but it does not limit whether there is contact or connection between other parts of the vertical plate 22 and the bracket 1, only defining that the side of the vertical plate 22 away from the bottom plate 21 finally abuts and supports against the upper part of the bracket 1.

[0037] Further, the side of the vertical plate 22 away from the bottom plate 21 can also be fixedly connected to the upper part of the bracket 1, for example, by welding. Compared with only abutting and supporting, the connection stability between the vertical plate 22 and the bracket 1 is stronger, thereby improving the supporting effect of the vertical plate 22 on the bracket 1.

[0038] In a specific embodiment, please refer to Figure 2 and Figure 3 , the external connection member 3 is in an "L" shape. One limb of the "L"-shaped external connection member 3 can be fixedly connected to the lower part of the support member 2 through bolts 4. The other limb of the external connection member 3 is provided with expansion screw holes 31 for fixedly connecting to an external load-bearing object. An external expansion screw can pass through the expansion screw holes 31 to fixedly connect the external connection member 3 to the external load-bearing object. Specifically, a plurality of spaced oblong holes 5 are provided on the limb of the external connection member 3 fixedly connected to the lower part of the support member 2. The support member 2 is also provided with oblong holes 5. The oblong holes 5 on the support member 2 are perpendicular to the oblong holes 5 on the external connection member 3. In practical applications, the bolts 4 can pass through the oblong holes 5 of the two from one side, and nuts 6 are installed on the other side to fixedly connect the support member 2 and the external connection member 3. In practical applications, the oblong holes 5 of the support member 2 can correspond to different oblong holes 5 on the external connection member 3, so as to adjust the relative positions of the support member 2 and the external connection member 3, which has good flexibility. Preferably, a washer 7 can also be provided between the nut 6 and the external connection member 3 to play a buffering role.

[0039] Further, a reinforcing plate 8 can also be provided at the "L" - shaped angle of the external connection member 3. Optionally, the number of the reinforcing plates 8 can be one or more. Optionally, the reinforcing plate 8 includes, but is not limited to, a triangular reinforcing plate or a trapezoidal reinforcing plate. Figure 2 As shown in the figure, it is a trapezoidal reinforcing plate. The reinforcing plate 8 is connected to the "L" - shaped external connection member 3 and cooperates to form a triangular structure, making the structure of the external connection member 3 more stable and having a better supporting effect on the support member 2 and the bracket 1.

[0040] In a specific embodiment, a skirting board 9 is further included. The skirting board 9 can be fixedly connected to the side wall of the bracket 1 through screws 10. Specifically, please refer to Figure 2 and Figure 4 , a plurality of screw holes 14 are spacedly arranged on the side wall of the bracket 1. A plurality of through holes corresponding to the screw holes 14 are provided on the skirting board 9. The screws 10 pass through the through holes and are threadedly connected to the screw holes 14 to squeeze the skirting board 9 onto the bracket 1, realizing the fixed connection between the skirting board 9 and the bracket 1.

[0041] In a specific embodiment, please refer to Figure 4, a kidney-shaped hole 5 corresponding to the dust-falling hole of the external sill is also provided on the upper part of the bracket 1. During actual use, impurities such as water, dust, and materials from the outside can fall through the dust-falling hole of the external sill and the kidney-shaped hole 5 of the bracket 1, thereby avoiding water accumulation and dust accumulation in the sill and improving the usage experience.

[0042] In a preferred embodiment of the present utility model, please refer to Figure 1 and Figure 5 , the number of the support members 2 and the external connection members 3 is the same and both are multiple. Different external connection members 3 are correspondingly connected to different support members 2, and the multiple support members 2 and the multiple external connection members 3 are all arranged at intervals along the extension direction of the bracket 1. In actual application, the distance between adjacent support members 2 and adjacent external connection members 3 can be adaptively designed according to the length of the external sill and the load-bearing capacity requirement of the external sill. The stronger the load-bearing capacity required by the external sill, the smaller the distance between adjacent support members 2 and adjacent external connection members 3.

[0043] Please refer to Figure 5 , the present utility model also provides a sill, which includes the sill supporting assembly described in any of the above embodiments. The sill (referring to the external sill 15) is fixedly connected to the upper part of the bracket 1 to be supported by the bracket 1. Based on the reasonable structural design of the bracket 1, the sill of the present utility model has good load-bearing capacity, stability, and safety.

[0044] In summary, a sill supporting assembly of the present utility model and a sill including the same, wherein the bracket 1 of the sill supporting assembly is supported by the support members 2 and has good structural stability. Specifically, the support members 2 support both the lower and upper parts of the bracket 1 simultaneously. Therefore, compared with the traditional bracket, the bracket 1 of the present utility model has stronger load-bearing capacity, better reliability, and can better support the external sill 15. And the sill proposed by the present utility model, by being supported by the sill supporting assembly of the present utility model, has good load-bearing capacity, can meet the load-bearing requirements for large-weight users and heavy forklifts to enter and exit, and has a good usage experience.
