[0024] See also Figure 1 , Figure 2 and Figure 3 , Figure 1 This is a schematic diagram of the structure of the support structure for the corridor of the utility model. Figure 2 This is a schematic diagram of the interior of the supporting structure of the corridor of the utility model (steel beams and connecting steel plates are not shown). Figure 3 for Figure 2A support structure for a corridor, comprising a column 1 and a plurality of inclined columns 2 spaced apart at the top of the outer wall of the column 1, the column 1 comprising a first steel pipe 11, a first inner partition steel plate 12 spaced apart on the inner wall of the first steel pipe 11 along the length direction of the first steel pipe 11, and a first concrete core 13 disposed in the first steel pipe 11, the first inner partition steel plate 12 being provided with a first grouting hole 14, the inclined column 2 comprising a second steel pipe 21, a second inner partition steel plate 22 spaced apart on the inner wall of the second steel pipe 21 along the length direction of the second steel pipe 21, and a second concrete core 23 disposed in the second steel pipe 21, the second inner partition steel plate 22 being provided with a second grouting hole 24.

[0025] A plurality of inclined columns 2 are arranged on the columns 1. The inclined columns 2 are arranged obliquely and connected to the corridor 5 of the L-shaped structure, so that the load of the corridor 5 can be evenly transmitted to the columns 1. The columns 1 and the inclined columns 2 both include an external steel pipe and an inner partition steel plate and a concrete core inside the steel pipe, so as to ensure the support and rigidity of the columns 1 and the inclined columns 2. The concrete core inside the steel pipe can increase the seismic performance of the supporting structure. The first grouting hole 14 on the first inner partition steel plate 12 and the second grouting hole 24 on the second inner partition steel plate 22 can facilitate the pouring of concrete. In one embodiment, the first inner partition steel plate 12 and the second inner partition steel plate 22 are both arranged horizontally.

[0026] Since the top of the inclined column 2 is connected to the corridor 5, and the top of the column 1 is connected to multiple inclined columns 2, the pressure is relatively large. In one embodiment, the first concrete core 13 and the second concrete core 23 both include a first concrete layer 131 and a second concrete layer 132 connected in sequence. The first concrete layer 131 is located above the second concrete layer 132, and the strength grade of the concrete of the first concrete layer 131 is higher than the strength grade of the concrete of the second concrete layer 132. The first concrete layer 131 at the top of the inclined column 2 and the top of the column 1 adopts concrete with a higher strength grade to ensure the compressive strength of the top of the column 1 and the inclined column 2, while the second concrete layer 132 at the middle and bottom of the inclined column 2 and the column 1 adopts concrete with a lower strength grade, which reduces the construction cost while ensuring the support and rigidity of the column 1 and the inclined column 2. In one embodiment, the first concrete layer 131 adopts C80 concrete, and the second concrete layer 132 adopts C50 concrete. In one embodiment, the height of the first concrete layer 131 is 1.5m.

[0027] In one embodiment, the top end of the first steel pipe 11 is closed, and a third grouting hole is provided on the closed section of the first steel pipe 11. This arrangement makes the column 1 more beautiful, and the third grouting hole facilitates pouring concrete into the column 1. The top end of the first steel pipe 11 is preferably closed with a hemispherical plate.

[0028] In one embodiment, the number of inclined columns 2 is at least three. More than three inclined columns 2 are arranged at equal intervals to ensure that the L-shaped structure corridor 5 can be stably supported. In one embodiment, a steel beam 3 is provided between two adjacent inclined columns 2, and a connecting steel plate 4 is provided between two adjacent inclined columns 2. By rigidly connecting and tying the steel beam 3 provided in the middle of the inclined column 2 and adding the connecting steel plate 4 to form a connecting column, the lateral stiffness is effectively increased, so that the lateral displacement can be effectively controlled to achieve stable support for the L-shaped structure corridor 5. In one embodiment, the top of the connecting steel plate 4 is welded to the bottom of the steel beam 3.

[0029] Compared with the prior art, the beneficial effects of the utility model are as follows: for the L-shaped corridor 5, only a single column 1 is provided for support, and a plurality of inclined columns 2 are provided on the column 1 to connect with the corridor 5, thereby reducing the site occupied under the corridor 5 while ensuring the structural safety of the corridor 5 and increasing the aesthetics; the column 1 and the inclined column 2 both include an external steel pipe and an internal partition steel plate and a concrete core inside the steel pipe, thereby ensuring the support and rigidity of the column 1 and the inclined column 2, and the concrete core inside the steel pipe can increase the seismic resistance of the supporting structure.

[0030] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Therefore, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
