[0044] In this embodiment, the composition of the connection structure 300 is defined.

[0045] The connection structure 300 includes two side panels 310, a first gasket 320, a plurality of first fasteners 330 and a plurality of second fasteners 340. Each of the two side panels 310 includes a first connecting portion 312, a second connecting portion 314 and a third connecting portion 316, and the second connecting portion 314 is connected between the first connecting portion 312 and the third connecting portion 316.

[0046] The first connection part 312 and the reinforced concrete beam 200 are located on the same side of the steel tube concrete column 100. The reinforced concrete beam 200 is located between the first connection parts 312 of the two side plates 310.

[0047] The third connection portion 316 is located on the side of the steel tube concrete column 100 away from the reinforced concrete beam 200. The first gasket 320 is located between the third connection portions 316 of the two side plates 310, and the plurality of second fasteners 340 are used to assemble the third connection portions 316 of the two side plates 310 and the first gasket 320 together.

For example, all of the cavity wall of the installation cavity 318 fits with the outer surface of the steel tube concrete column 100.

[0049] That is, the two side plates 310 , the first gasket 320 , the plurality of first fasteners 330 and the plurality of second fasteners 340 cooperate to effectively assemble the reinforced concrete beam 200 and the steel tube concrete column 100 together, while also being able to meet the use requirements of abutting against the auxiliary support assembly 400 .

[0050] It is understandable that the first gasket 320 is located between the third connecting parts 316 of the two side panels 310. The first gasket 320 is provided to indirectly increase the matching area of ​​the two third connecting parts 316, which is conducive to improving the stability and reliability of the assembly of the two third connecting parts 316. In addition, this structural arrangement can reduce the machining accuracy requirements for the two side panels 310 and reduce installation errors while ensuring the effectiveness of the connection structure 300 in connecting the steel tube concrete column 100 and the reinforced concrete beam 200, which is conducive to improving the processing efficiency and assembly efficiency of the product.

[0051] In some embodiments, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Fig.11 and Fig.12 As shown, the third connecting portion 316 includes: a connecting plate 3162, connected to the second connecting portion 314, and the connecting plate 3162 is against the first gasket 320; a first rib plate 3164; a second rib plate 3166, the first rib plate 3164 and the second rib plate 3166 are both connected to the second connecting portion 314 and the connecting plate 3162, along the height direction of the steel tube concrete column 100, the second rib plate 3166 and the first rib plate 3164 are arranged at intervals, and the end surface of the second rib plate 3166 away from the first rib plate 3164 is a first inclined surface 3168; The end face of the auxiliary support assembly 400 facing the connection structure 300 includes a second inclined surface 410, the second inclined surface 410 is in contact with the connection plate 3162, and the second inclined surface 410 is in contact with the first inclined surface 3168; along the first gasket 320 to the connection plate 3162, the distance from the second inclined surface 410 to the bottom end 110 of the steel tube concrete column gradually decreases; wherein, by adjusting the tightening force of at least one of the first fastener 330 and the second fastener 340, the supporting force between the connection structure 300 and the auxiliary support assembly 400 can be adjusted.

[0052] In this embodiment, the structure of the third connecting portion 316 is further defined.

[0053] The third connecting portion 316 includes a connecting plate 3162, a first rib plate 3164, and a second rib plate 3166.

The second rib plate 3166 connects the second connecting portion 314 and the connecting plate 3162. The first rib plate 3164 and the second rib plate 3166 have the function of strengthening the structural strength of the connection between the connecting plate 3162 and the second connecting portion 314.

[0055] Specifically, the connection between the auxiliary support assembly 400 and the connection structure 300 is an auxiliary fulcrum. Combined with the matching structure of the auxiliary support assembly 400, the connection plate 3162 and the second rib plate 3166, by adjusting the tightening force of at least one of the first fastener 330 and the second fastener 340, the supporting force between the connection structure 300 and the auxiliary support assembly 400 can be adjusted, so that the supporting force of the auxiliary fulcrum can reach half of the total weight of the reinforced concrete beam 200, so as to effectively reduce the pressure of the reinforced concrete beam 200 on the root tension position of the corbel assembly 500, and prevent the corbel assembly 500 from being damaged due to excessive force.

[0056] That is to say, the tightening force of at least one of the first fastener 330 and the second fastener 340 can be adjusted according to the specific actual design requirements to correspondingly adjust the supporting force between the connection structure 300 and the auxiliary support assembly 400. It can also be said that the auxiliary fulcrum is an auxiliary fulcrum with adjustable supporting force. This setting can reduce the pressure of the reinforced concrete beam 200 on the root tension position of the corbel assembly 500, and prevent the corbel assembly 500 from being damaged due to excessive force.

The elastic member 520 has a first end 522 and a second end 524, and the first end 522 and the second end 524 are arranged at intervals along the first direction. The first end 522 is arranged at intervals from the reinforced concrete beam 200, and the second end 524 is connected to the reinforced concrete beam 200.

[0066] Since the first end portion 522 is spaced apart from the reinforced concrete beam 200 , spatial support is provided for the deformation of the elastic member 520 .

[0067] Specifically, by limiting the matching structure of the corbel assembly 500, the steel tube concrete column 100 and the reinforced concrete beam 200, the elastic member 520 is used to limit the displacement of the reinforced concrete beam 200 in the first direction, and the load on the reinforced concrete beam 200 is released, so that the end rotation and / or deformation of the reinforced concrete beam 200 is not easily transferred to the steel tube concrete column 100, so that the transition connection structure 10 between the steel tube concrete column and the reinforced concrete beam is more stable and reliable.

[0068] Optionally, the connecting member comprises a spring plate.

[0069] In some embodiments, Figure 1 and Figure 3 As shown, the corbel assembly 500 also includes: a reinforcing plate 530, which is connected between the corbel 510 and the first end 522 of the elastic member 520; the transitional connection structure 10 between the steel tube concrete column and the reinforced concrete beam also includes a second gasket 600, and the reinforced concrete beam 200 and the second end 524 of the elastic member 520 are connected via the second gasket 600; wherein, along the first end 522 to the second end 524, the distance from the portion of the elastic member 520 located between the first end 522 and the second end 524 to the reinforced concrete beam 200 gradually increases.

[0070] In this embodiment, the structure of the corbel assembly 500 is further defined.

[0071] Specifically, the corbel assembly 500 further includes a reinforcing plate 530 . The reinforcing plate 530 is connected between the corbel 510 and the first end 522 of the elastic member 520 .

[0072] The transitional connection structure 10 between the steel tube concrete column and the reinforced concrete beam also includes a second gasket 600 , which is located between the reinforced concrete beam 200 and the second end 524 of the elastic member 520 , and the reinforced concrete beam 200 and the second end 524 of the elastic member 520 are connected via the second gasket 600 .

[0073] From the first end 522 to the second end 524, the distance between the portion of the elastic member 520 located between the first end 522 and the second end 524 and the reinforced concrete beam 200 gradually increases. This arrangement provides spatial support for the deformation of the elastic member 520. In other words, while ensuring the structural strength of the upper edge of the reinforced corbel 510 and increasing the stability and reliability of the assembly of the second end 524 of the elastic member 520 and the reinforced concrete beam 200, it can meet the requirements of the first end 522 of the elastic member 520 and the reinforced concrete beam 200 being arranged at intervals, and meeting the requirements of the second end 524 of the elastic member 520 and the reinforced concrete beam 200 being connected.

[0074] The structural setting of the reinforcing plate 530 can enhance the structural strength of the upper edge of the corbel 510 .

[0075] Optionally, the transitional connection structure 10 between the steel tube concrete column and the reinforced concrete beam further includes a third fastener, which is used to connect the second end 524 of the elastic member 520 , the second gasket 600 and the reinforced concrete beam 200 .

[0076] In some embodiments, Figure 3 , Figure 6 , Figure 7 and Fig.10As shown, the transitional connection structure 10 between the steel tube concrete column and the reinforced concrete beam also includes: a beam end connector 700, along the first direction, the beam end connector 700 is located on one side of the steel tube concrete column 100, the beam end connector 700 is provided with a slot 710, a part of the reinforced concrete beam 200 is inserted into the slot 710, the outer surface of the beam end connector 700 and the part of the reinforced concrete beam 200 located outside the beam end connector 700 are smoothly transitioned, and the connection structure 300 and the part of the reinforced concrete beam 200 located in the slot 710 are connected through the beam end connector 700; along the height direction of the steel tube concrete column 100, the reinforced concrete beam 200 and the reinforcing plate 530 are arranged at intervals; the beam end connector 700 has an extension plate 720, the extension plate 720 is located between the steel tube concrete column 100 and the elastic member 520, and the extension plate 720 is in contact with the reinforcing plate 530.

[0077] In this embodiment, the composition structure of the transitional connection structure 10 between the steel tube concrete column and the reinforced concrete beam is further defined.

[0078] Specifically, the transitional connection structure 10 between the steel tube concrete column and the reinforced concrete beam further includes a beam end connector 700 .

[0079] Along the first direction, the beam end connector 700 is located at one side of the steel tube concrete column 100. The beam end connector 700 is provided with a slot 710, and a part of the reinforced concrete beam 200 is inserted into the slot 710. The outer surface of the beam end connector 700 and the part of the reinforced concrete beam 200 located outside the beam end connector 700 are smoothly transitioned. The slot 710 cooperates with the structure of the reinforced concrete beam 200 to effectively limit the reinforced concrete beam 200. It can ensure the smooth transition of the overall assembly dimensions of the beam end connector 700 and the reinforced concrete beam 200, and then ensure the matching dimensions of the reinforced concrete beam 200, the beam end connector 700 and the corbel assembly 500, and avoid the situation where the beam end connector 700 protrudes from the reinforced concrete beam 200 and causes interference with the corbel assembly 500.

[0080] The connection structure 300 and the portion of the reinforced concrete beam 200 located in the slot 710 are connected by the beam end connector 700, that is, the connection structure 300, the reinforced concrete beam 200 and the beam end connector 700 are effectively assembled into a whole.

[0081] The beam end connector 700 has an extension plate 720, which is located between the steel tube concrete column 100 and the elastic member 520, and the extension plate 720 abuts against the reinforcing plate 530. In other words, the reinforced concrete beam 200, the second gasket 600, the corbel assembly 500 and the beam end connector 700 cooperate to form a hinged structure, so that the load on the reinforced concrete beam 200 can be released, so that the end rotation and / or deformation of the reinforced concrete beam 200 is not easily transferred to the steel tube concrete column 100, and the structure is more stable and reliable.

[0082] In some embodiments, Figure 3 As shown, along the first direction, the beam end connector 700 and the steel tube concrete column 100 are arranged at intervals.

[0083] In this embodiment, the matching structure of the beam end connector 700 and the steel tube concrete column 100 is further defined, so that the beam end connector 700 and the steel tube concrete column 100 are arranged at intervals. This arrangement is conducive to reducing the processing dimensional accuracy requirements of the beam end connector 700 and the steel tube concrete column 100, while ensuring the stability and reliability of the assembly of the transitional connection structure 10 between the steel tube concrete column and the reinforced concrete beam, it is conducive to reducing the processing cost of the beam end connector 700 and the steel tube concrete column 100, and further conducive to reducing the production cost of the transitional connection structure 10 between the steel tube concrete column and the reinforced concrete beam.

[0084] In some embodiments, Figure 1 , Figure 6 and Fig. 9 As shown, the transitional connection structure 10 of the steel tube concrete column and the reinforced concrete beam further includes: a diagonal stay assembly 800 , which is connected between the steel tube concrete column 100 and a side of the connection structure 300 away from the corbel assembly 500 .

[0085] In this embodiment, the composition structure of the transitional connection structure 10 between the steel tube concrete column and the reinforced concrete beam is further defined.

[0086] The transitional connection structure 10 between the steel tube concrete column and the reinforced concrete beam further includes a diagonal stay assembly 800 .

[0087] The inclined-stayed assembly 800 is connected to the steel tube concrete column 100, and the inclined-stayed assembly 800 is connected to the side of the connection structure 300 away from the corbel assembly 500. The inclined-stayed assembly 800 is connected between the steel tube concrete column 100 and the connection structure 300. That is, the inclined-stayed assembly 800 that pulls the diagonal span is provided.

[0088] The inclined-stay assembly 800 and the corbel assembly 500 are arranged opposite to each other.

[0089] Due to the provision of the inclined stay assembly 800, the end rotation caused by the load on the reinforced concrete beam 200 basically does not affect the supporting performance of the auxiliary support. When the load on the reinforced concrete beam 200 changes, the auxiliary support assembly 400 can still produce strong supporting performance, which can improve the stability of the transitional connection structure 10 between the steel tube concrete column and the reinforced concrete beam.

[0090] In some embodiments, Fig.11 As shown, the first connecting portion 312 includes a first mating segment 3122 and a second mating segment 3124 , and the first mating segment 3122 is connected between the second connecting portion 314 and the second mating segment 3124 ; the first fastener 330 is connected to the first mating segment 3122 , and the diagonal assembly 800 is connected to the second mating segment 3124 .

[0091] In this embodiment, the matching structure of the connection structure 300 and the oblique-stayed assembly 800 is further defined.

[0092] Specifically, the first connecting portion 312 includes a first matching segment 3122 and a second matching segment 3124 . The first matching segment 3122 is located between the second matching segment 3124 and the second connecting portion 314 , and the first matching segment 3122 is connected between the second connecting portion 314 and the second matching segment 3124 .

[0093] The first mating section 3122 is used to cooperate with the first fastener 330 to effectively connect the steel tube concrete column 100 and the reinforced concrete beam 200 .

[0094] The second mating section 3124 is used to cooperate with the oblique-stayed assembly 800 to support and fix the oblique-stayed assembly 800 .

[0095] That is to say, the connection structure 300 is reasonably utilized, so that the connection structure 300 not only has the function of connecting the steel tube concrete column 100 and the reinforced concrete beam 200, but also has the function of bearing the inclined-stayed assembly 800.

[0096] In some embodiments, Fig. 9 and Fig.11 As shown, the inclined-stayed assembly 800 includes: an inclined-stayed plate 810, which is connected to the steel tube concrete column 100; an inclined-stayed span 820, which is sleeved on the outside of the two second matching sections 3124, and the inclined-stayed span 820 is connected to each second matching section 3124; and a plurality of inclined-stayed rods 830, each of which is connected between the inclined-stayed plate 810 and the inclined-stayed span 820, and the plurality of inclined-stayed rods 830 are arranged at intervals.

[0097] In this embodiment, the diagonal stay assembly 800 includes a diagonal stay plate 810 , a diagonal stay span 820 , and a plurality of diagonal stay rods 830 .

[0098] The inclined plate 810 is connected to the steel tube concrete column 100. The inclined span 820 is sleeved outside the two second matching sections 3124, and the inclined span 820 is connected to each second matching section 3124. Each inclined rod 830 is connected between the inclined plate 810 and the inclined span 820, and a plurality of inclined rods 830 are arranged at intervals.

[0099] This arrangement can meet the use requirement of connecting the inclined-stayed assembly 800 between the steel tube concrete column 100 and the side of the connecting structure 300 facing away from the corbel assembly 500 .

[0100] It can be understood that the oblique span 820 is a groove-shaped structure, and the oblique span 820 is sleeved on the outer sides of the two second matching sections 3124 .

[0101] The plurality of diagonal tie rods 830 are arranged at intervals along the second direction.

[0102] Optionally, the corbel assembly 500 and the auxiliary support assembly 400 are first welded to the steel tube concrete column 100, and the reinforced concrete beam 200 and the beam end connector 700 are fixed together during processing. Then the reinforced concrete beam 200 and the beam end connector 700 are placed together on the corbel assembly 500, and a second gasket 600 is padded between the elastic member 520 (such as a spring sheet) and the reinforced concrete beam 200, and then bolted. Then the two side panels 310 are installed, and the bolts (i.e., the first fastener 330 and the second fastener 340) at the left and right ends of the side panels 310 are tightened alternately. The supporting force of the auxiliary fulcrum (i.e., the connection between the auxiliary support assembly 400 and the connecting structure 300) is adjusted by adjusting the tightening force acting on the third connecting portion 316. The supporting force of the auxiliary fulcrum is made to be half of the total weight of the reinforced concrete beam 200. Then, the inclined plate 810 and the inclined span 820 are welded to the second matching section 3124 of the steel tube concrete column 100 and the side plate 310 respectively.

[0103] In the present application, the extension plate 720 of the beam end connector 700 is directly placed on the reinforcement plate 530 of the corbel assembly 500, and the displacement of the reinforced concrete beam 200 in the first direction is limited by the spring plate. The reinforced concrete beam 200, the second gasket 600, the corbel assembly 500 and the beam end connector 700 cooperate to form a hinged structure, which releases the load on the reinforced concrete beam 200, so that the end rotation and / or deformation of the reinforced concrete beam 200 is not easily transferred to the steel tube concrete column 100, and the structure is more stable.

[0104] The present application provides an adjustable auxiliary fulcrum to reduce the pressure of the extension plate 720 on the tension position of the root of the corbel 510, thereby preventing the corbel 510 from being damaged due to excessive force.

[0105] The present application provides a pulling diagonal span (i.e., the diagonal assembly 800) so that the end rotation caused by the load on the reinforced concrete beam 200 basically does not affect the supporting performance of the auxiliary fulcrum, ensuring that when the load on the reinforced concrete beam 200 changes, the auxiliary support assembly 400 can still produce strong supporting performance.

To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the attached claims.
