In one embodiment, as shown in fig. 2 to 9, in the collision area between the upright 90 and the main beam 100, one or two existing angle steels 901 interfere with the main beam 100 to be built, because the upright 90 interferes relatively little, considering that the original structure is reserved as much as possible, only the part of the upright 90 is cut, the number of the supporting parts 3 is selected as a group, the supporting parts 3 are arranged in parallel with the upright 90, a channel 5 for the main beam 100 to pass through is formed between the supporting parts 3 and the upright 90, and two ends of the reinforcing rod 4 are respectively connected with the supporting parts 3 and the upright 90, so that the rigidity of the supporting structure is radially enhanced, and a three-dimensional stable support is formed; the surface of the pallet 1 facing the channel 5 is an inner surface 19a, the first side portion 1a and the second side portion 1b opposite to the inner surface 19a are respectively connected with at least one reinforcing rod 4, and the other two opposite side portions are a third side portion 1c and a fourth side portion 1d, wherein the third side portion 1c is fixedly connected with the supporting portion 3, generally can be welded or bolted, the edge of the fourth side portion 1d is embedded and tightly attached with the periphery of the upright post 90, and then the two are welded into a whole.

In order to ensure the stability and the bearing safety coefficient of the supporting structure, the number of the supporting parts 3 is two or more than two, at least one group of supporting parts 3 are respectively arranged on two sides of the upright post 90, the supporting parts 3 are arranged in parallel with the upright post 90, a channel 5 for a main beam 100 to pass through is formed between the supporting parts 3 on two sides of the upright post 90, two ends of the reinforcing rod 4 are respectively connected with the supporting parts 3 on two sides of the upright post 90, and the rigidity of the supporting structure is reinforced along the radial direction so as to form a three-dimensional stable support; the pallet 1 is divided into left and right parts along the central axis of the upright 90, one surface of the pallet 1 located at any part facing the channel 5 is an inner side surface 19b, two opposite side parts of the inner side surface 19b are respectively connected with at least one reinforcing rod 4, one of the other opposite side parts is fixedly connected with the supporting part 3, and the other edge can be tightly embedded with the periphery of the upright 90 according to the following reinforcing method on the basis of the device, and then the two parts are welded into a whole.

Through the implementation of the device, the upright post 90 is sufficiently reinforced and supported, so that the whole upright post 90 does not need to be underpinned, the construction difficulty is low, and the cost is low.
The specific implementation is as follows:
Dispatching a staff to locate on site, and surveying the spatial position relation between the main beam 100 to be built and the upright post 90 which is constructed in the earlier stage; after investigation, the column reinforcement structure is added at the position corresponding to the height of the column 90 to complete the connection of all parts including but not limited to the supporting plate 1, the reinforcing angle steel 31 of the reinforcing rod 4 and the lacing plate 32, and the connection mode includes but not limited to welding and bolting; cutting the structure in the area of conflict between the upright 90 and the main beam 100 after the upright reinforcement structure is thoroughly formed with support capability, mainly by the existing angle 901 of the upright 90 and other auxiliary structures, such as the existing gusset plate 902 (mentioned below); after the cutting is completed, the channel 5 is smooth, the girder 100 construction can be conveniently carried out, the construction process of the girder 100 is generally that the reinforcing steel bar passes through the channel 5, is bound and is supported, and concrete pouring can be carried out after the formwork is supported to form the girder 100, and the site construction is particularly taken as the reference. In the construction process of the main beam 100, the vertical column 90 interfered by the supporting plate 1 and the supporting frame 6 still can maintain the bearing function in the axial direction, so that the whole vertical column 90 is not required to be underpinned, the construction difficulty is low and the cost is low.
It should be appreciated that, due to the complex construction site conditions, the direction and location of interference between the upright 90 and the main beam 100 may be different, and thus it is necessary to count the existing angle 901 in the area of interference between the upright 90 and the main beam 100 prior to erecting the upright reinforcing structure; according to the counting result selection scheme, when the number of the related existing angle steels 901 is one or two, the number of the supporting parts 3 is one group, when the number of the related existing angle steels 901 is three or four, the number of the supporting parts 3 is two or more than two groups, and the scheme of the corresponding upright post reinforcing structure is selected; in addition, after the basement multi-layer structure is completed and the related support is replaced, the portion of the structure such as the upright post 90 above the pit bottom should be cut off to complete the final construction.
In some embodiments, like the half of the upright 90 in fig. 2 to 17, the supporting portion 3 includes two reinforcing angle steels 31, the two reinforcing angle steels 31 are arranged side by side, the side surfaces 311 of the two reinforcing angle steels 31 are located on the same plane to form a U shape, and the side surface adjacent to the side surface 311 is fixedly connected with the reinforcing rod 4, so that the area is large and the connection is more stable, and the bearing performance and the stability in the axial direction are better. The support portion 3 includes a gusset plate 32, and the gusset plate 32 is disposed on the side surfaces 311 of the two reinforcing angle steels 31 to strengthen the rigidity of the support portion 3, and the gusset plate 32 and the reinforcing angle steels 31 may be welded or bolted, specifically, according to the design.
In some embodiments, as shown in fig. 2 to 17, the column reinforcement structure further includes a plurality of reinforcement plates 2, the reinforcement plates 2 connecting the pallet 1 with the columns 90; wherein, the pallet 1 located above is connected with the upper portion of the upright 90, the pallet 1 located below is connected with the lower portion of the upright 90, and the connection rigidity can be increased by the reinforcing plate 2 so as to achieve better bearing, and the pallet 1 located above is not directly connected with the lower portion of the upright 90, and also not reinforced by the reinforcing plate 2. The reinforcing plate 2 is a metal plate with a certain shape and thickness, the reinforcing plate 2 is erected on the supporting plate 1, and the side part of the reinforcing plate 2 is connected with the upright post 90; the extending direction of the reinforcing plate 2 can be flexible, and the reinforcing plate 2 is generally connected along the normal plane of the stress direction, and a part of the reinforcing plate 2 can be designed to form a certain included angle so as to increase the impact resistance in the radial direction, specifically based on the design; the reinforcing plate 2 and the upright post 90 can be welded or bolted, and the reinforcing plate 2 and the supporting plate 1 can be welded, bolted or integrally connected.
In addition, the upright 90 may have a plurality of existing batten plates 902 on the side surfaces thereof as a supporting structure, and the portion of the upright 90 having the existing batten plates 902 may be preferentially selected for connection, instead of being directly connected with the existing angle steel 901 of the upright 90, so that the advantage is that damage to a direct bearing member is avoided, and acting force can be uniformly transmitted to the existing angle steel 901 through the existing batten plates 902, so that uneven stress of the existing angle steel 901 is prevented. Therefore, if it is found in the implementation of the reinforcement method that the existing batten plates 902 are not connected at the positions corresponding to the collision areas of the upright posts 90, one or more existing batten plates 902 may be welded to the upright posts 90 in advance, so that the subsequent connection is convenient.
