[0041] Referring to Figures 1-9 , this application relates to a bent cap 6 support for a large-volume hollow pier 3. The bent cap 6 support includes: at least a pair of first embedded components 1 and at least a pair of second embedded components 2. At least a pair of the first embedded components 1 are respectively embedded in the left and right side walls of the large-volume hollow pier 3, and at least a pair of the second embedded components 2 are respectively embedded in the front and rear side walls of the large-volume hollow pier 3. A first bracket 4 is connected to each of the first embedded components 1, and a second bracket 5 is connected to each of the second embedded components 2. The bent cap 6 is arranged on the tops of the first bracket 4 and the second bracket 5. When installed in this way, by embedding the first embedded components 1 and the second embedded components 2 into the respective side walls of the large-volume hollow pier 3 in the above manner, then connecting the first bracket 4 to each of the first embedded components 1, connecting the second bracket 5 to each of the second embedded components 2, and finally arranging the bent cap 6 on the tops of the first bracket 4 and the second bracket 5, it is thus possible to use the embedded components in cooperation with the brackets to form a bent cap 6 support for supporting the bent cap 6, avoiding embedding PVC pipes and inserting pin rods for supporting the bent cap 6, thereby achieving a reduction in quality requirements and a decrease in the difficulty of installation and disassembly.

[0042] Refer to Figure 1 and Figure 3 Preferably, both the first embedded component 1 and the second embedded component 2 are in three pairs. The three pairs of the first embedded components 1 are respectively embedded at the middle and positions close to the front and rear side walls on the left and right side walls of the mass concrete hollow pier 3; the cooperation of the three pairs of the first embedded components 1 and the second embedded components 2 with the corresponding first bracket 4 and second bracket 5 can effectively ensure the stability of the capping beam 6 supported by the capping beam 6 bracket formed.

[0043] Refer to Figures 1-3 and Figures 6-9 Preferably, the first embedded component 1 includes: a first upper embedded part 11 and a first lower embedded part 12. Among them, the first lower embedded part 12 is located directly below the first upper embedded part 11, and the first upper embedded part 11 and the first lower embedded part 12 are welded to the first bracket 4; the second embedded component 2 includes: a second upper embedded part 21 and a second lower embedded part 22. Among them, the second lower embedded part 22 is located directly below the second upper embedded part 21, and the second upper embedded part 21 and the second lower embedded part 22 are welded to the second bracket 5.

[0044] Furthermore, the first upper embedded part 11 includes: a first upper steel plate 111 and several first upper steel bars 112. Among them, the first upper steel plate 111 is fixed in the mass concrete hollow pier 3, and several first upper steel bars 112 are welded to the first upper steel plate 111 in a three-row and three-column form; the first lower embedded part 12 includes: a first lower steel plate 121 and several first lower steel bars 122. Among them, the first lower steel plate 121 is fixed in the mass concrete hollow pier 3, and several first lower steel bars 122 are welded to the first lower steel plate 121 in a three-row and two-column form; the first bracket 4 is welded to several first upper steel bars 112 and several first lower steel bars 122.

[0045] Even further, the second upper embedded part 21 includes: a second upper steel plate 211 and several second upper steel bars 212. Among them, the second upper steel plate 211 is fixed in the mass concrete hollow pier 3, and several second upper steel bars 212 are welded to the second upper steel plate 211 in a three-row and two-column form; the second lower embedded part 22 includes: a second lower steel plate 221 and several second lower steel bars 222. Among them, the second lower steel plate 221 is fixed in the mass concrete hollow pier 3, and several second lower steel bars 222 are welded to the second lower steel plate 221 in a two-row and two-column form; the second bracket 5 is welded to several second upper steel bars 212 and several second lower steel bars 222.

[0046] When installed in this way, by fixing the first upper steel plate 111 and the first lower steel plate 121 to the corresponding positions on the left and right side walls of the large-volume hollow pier 3, then welding the first upper steel bars 112 in a three-row and three-column form on the first upper steel plate 111, welding the first lower steel bars 122 in a three-row and two-column form on the first lower steel plate 121, and then welding one end of the first support member 41 and the first diagonal support member 42 to the first upper steel bars 112 and the first lower steel bars 122 respectively, and welding the other end of the first diagonal support member 42 to the first support member 41, thus forming three pairs of triangular support frames, which are respectively arranged on the left and right side walls of the large-volume hollow pier 3, greatly improving the bearing capacity of the bracket of the capping beam 6. Similarly, the second upper steel plate 211, the second lower steel plate 221, the second upper steel bars 212, and the second lower steel bars 222 can also form three pairs of triangular support frames, which are respectively arranged on the left and right side walls of the large-volume hollow pier 3, further improving the bearing capacity of the bracket of the capping beam 6.

[0047] It should be understood that since the length direction of the capping beam 6 is the left-right direction, the length of the first support member 41 is greater than the length of the second support member 51, and it needs to bear more gravity of the capping beam 6. Therefore, two first support members 43 are added on the basis of the triangular support frame to adapt to bearing greater gravity; while the length of the second support member 51 is shorter, and the gravity it needs to bear is relatively small, so only the triangular support frame is used for support.

[0048] It should also be understood that in this embodiment, the first support member 41 is made of double 32a I-beams, the first diagonal support member 42 is made of 32a I-beams, and the first support member 43 is made of 25a I-beams to ensure that it can bear more gravity of the capping beam 6; the second support member 51 is made of 32a I-beams, and the second diagonal support member 52 is made of 25a I-beams; to ensure that it can bear relatively less gravity of the capping beam 6.

[0049] Refer to Figures 3-5 , since the left and right side walls of the large-volume hollow pier 3 are in an outwardly convex arc shape, the length of the first bracket 4 in the middle should be shorter than the length of the first brackets 4 near the front and rear sides to ensure that the ends of the brackets are flush; however, such a design will cause a problem, that is, the bearing capacity of the first bracket 4 in the middle position is not as strong as that of the first brackets 4 on both sides. Therefore, the diameter of the first support member 43 at the middle position on the left and right side walls of the large-volume hollow pier 3 is set to be greater than the diameter of the first support member 43 at the positions near the front and rear side walls on the left and right side walls of the large-volume hollow pier 3, which can ensure that the bearing capacity of the first bracket 4 in the middle is equivalent to that of the first brackets 4 on both sides.

[0050] Refer to Figure 1 and Figure 2, a load-bearing member 7 is further provided between the first bracket 4, the second bracket 5 and the capping beam 6; the load-bearing capacity of the capping beam 6 support is further improved through the load-bearing member 7; it should be understood that the load-bearing member 7 is a 14a I-beam.

[0051] Referring to Figures 1-3 , the present application also relates to a capping beam 6 support system, which includes: a capping beam 6 support for a large-volume hollow pier 3. This system achieves the same technical effects as the capping beam 6 support of the large-volume hollow pier 3.

[0052] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
