Problems solved by technology
Under the premise of ensuring the reliable and safe connection between the newly added steel beam and the existing column, the connection structure avoids the damage to the existing structure and the difficulty of planting reinforcement in the beam-column joint area, and solves the problem of the existing structural beam-column joint area. The predicament of dense steel bars and difficulty in planting bars makes construction more convenient and easy

Embodiment Construction
[0028] see Figure 1-Figure 3 As shown, the embodiment of the present invention provides a quick-assembled connection structure between a new steel beam and an existing concrete column. The connection structure includes an upper ring hoop 4 and a lower ring hoop 5 fitted on the existing concrete column 1, The upper hoop 4 and the lower hoop 5 are connected by several strip steel plates 8 .
[0029] An upper anti-bending ring plate 6 is fixed on the outer wall of the upper ring hoop 4 , and a lower anti-bending ring plate 7 is fixed on the outer wall of the lower ring hoop 5 .
[0030] The upper anti-bending ring plate 6 and the lower anti-bending ring plate 7 both extend outward at the same position to form a rib plate, which are respectively the upper rib plate and the lower rib plate, and a web plate passes between the upper rib plate and the lower rib plate 9, the web 9 is connected to one of the strip steel plates 8, and is perpendicular to the strip steel plate 8.

The invention relates to a connecting structure of a newly-added steel beam and an existing concrete column and a construction method of the connecting structure, and belongs to the technical field of building structure engineering. The structure comprises a first hoop and a second hoop which are arranged on an existing concrete column in a sleeving mode, and is characterized in that the first hoop and the second hoop are connected through N connecting plates, a first annular anti-bending plate is fixedly connected outside the first hoop, a second annular anti-bending plate is fixedly connected outside the second hoop, and the N connecting plates are arranged between the first hoop and the second hoop. The first annular anti-bending plate and the second annular anti-bending plate extend outwards at the same position to form rib plates, the two rib plates are connected through a vertical web plate, and the vertical web plate is fixedly connected with one connecting plate. A large number of anchor bolts do not need to be implanted in a beam-column joint reinforcing steel bar dense area, the construction difficulty is greatly reduced, the original structure is not damaged, and the bearing capacity of the original structure is prevented from being weakened.
Description
technical field [0001] The invention belongs to the technical field of building structure engineering, in particular to a connection structure between newly added steel beams and existing concrete columns and a construction method thereof. Background technique [0002] At present, in the reinforcement and transformation of structures, due to the advantages of light weight, high strength, and easy construction, steel structures have become the preferred structural form for adding floors to existing structures. When adding steel beams, if the original structural columns are steel columns, additional Steel beams are easier. If the original structure is a concrete column, it is more troublesome. If the beam-column is a hinged connection, it is only necessary to connect the newly added steel beam web to the column. connect. The usual method is to connect the newly added steel beams with the existing columns through post-embedded parts to form rigid joints. However, this joint f...
