Technical Field

[0001] The utility model belongs to track technology, and in particular relates to a reinforcement component suitable for a concrete column. Background Art

[0002] The original subway depot parking lot was built in the open air, occupying too much land and with low space utilization. With the rapid development of the city, the original similar open-air infrastructure cannot adapt to the development needs of the new urban pattern. At the same time, this type of infrastructure is in operation and the subway cannot be shut down for demolition, renovation and reconstruction. More and more old infrastructure concrete projects are restricting urban development.

[0003] Similar subway depots have existed for a long time, and their structural functions cannot meet today's usage needs. Therefore, they are facing the fate of being renovated. For these old concrete structures, the general treatment method is mostly to dismantle and modify them, but this method is time-consuming, costly, and will generate too much construction waste; at the same time, the corresponding functions cannot be used temporarily, which reduces the quality of life of urban residents. It is time-consuming and labor-intensive, generates a lot of waste, and will cause social pressure. Based on the above needs, there is an urgent need for a structural reinforcement device suitable for the foundation beam of the concrete structure to reduce costs, increase benefits, and reduce social pressure during the renovation process.

[0006] The beam penetrates the fastener and is fixedly connected to the beam-column node of the column reinforcement structure;

[0007] The column base enclosure structure is fixedly connected to the column base node of the column reinforcement structure.

[0008] As a further improvement, the column reinforcement structure includes an outer angle steel fixed at the corner of the column and a plurality of tie plates connected between adjacent outer angle steels; the tie plates extend in a direction perpendicular to the axis of the column.

[0009] As a further improvement, the beam through-fastener is an equivalent stirrup connecting the outer angle steel of the center column or a combination of an equivalent flat steel and stirrups connecting the corner column;

[0010] The equivalent stirrups or stirrups penetrate the beam at the beam-column node and are welded to the corresponding outer angle steel of the beam and column at that location;

[0011] The equal generation flat steel is bridged and fixed to the beam surface of the beam at the node and the corners of the column surface connected to the same side of the beam surface.

[0012] As a further improvement, the column foot enclosure structure includes a column foot substitute flat steel, a cement soil body and a concrete body cast outside the column foot;

[0013] The upper end of the column foot or other flat steel is welded to the column foot section of the outer angle steel, and the lower end of the column foot or other flat steel is fixed in the floor slab at the bottom of the column foot;

[0014] The cement soil body and the concrete body are cast outside the column foot section of the column foot substitute flat steel and the outer angle steel welded with the column foot substitute flat steel;
