[0024] The present utility model will be further described below with reference to the drawings and embodiments.
[0025] Please refer to Figure 1-2 , the utility model provides a technical solution for the design and reinforcement structure of a building concrete column:
[0026] Example 1:
[0027] According to Figure 1 and Figure 2 as shown, it includes four angle steels 1 located at the four edges of the beam-column, and also includes an L-shaped connecting plate 21, an L-shaped docking plate 22 and two groups of connecting pieces. Long slots are respectively opened at both ends of the L-shaped docking plate 22. By setting the long slots, the L-shaped docking plate 22 and the L-shaped connecting plate 21 can be assembled according to the perimeter of the beam-column to be applicable to beam-columns with different perimeters, improving the practicability and applicability of the device.
[0028] The connecting piece is a screw 23 welded to the end of the L-shaped connecting plate 21. The threaded end of the screw 23 passes through the slot and is threadedly connected with a nut 24. By sleeving the L-shaped docking plate 22 and the L-shaped connecting plate 21 on the outer sides of the four angle steels 1 and screwing the nuts 24 one by one, the nut 24 presses the L-shaped docking plate 22, assembling the L-shaped docking plate 22 and the L-shaped connecting plate 21 together, so that the L-shaped docking plate 22 and the L-shaped connecting plate 21 are easy to assemble and disassemble.
[0029] After the L-shaped docking plate 22 and the L-shaped connecting plate 21 are assembled, they are fitted and sleeved on the outer sides of the four angle steels 1 to fix the four angle steels 1 on the beam-column, ensuring the fixing effect of the angle steels 1 and facilitating repeated use by users.
[0030] N reinforcing plates 3 are welded between adjacent two angle steels 1. Rubber strips 5 are respectively pasted on the two side faces of the angle steels 1 close to the beam-column. By setting the rubber strips 5, when the four angle steels 1 are fixed at the four edges of the beam-column, the rubber strips 5 can block the edge gaps of the angle steels 1, so as to inject structural grouting adhesive into the gap between the angle steels 1 and the beam-column through the injection holes 11.
[0031] N injection holes 11 are successively opened in the angle steels 1 from top to bottom. Threaded holes are respectively opened at both ends of the reinforcing plate 3. The threaded holes correspond to the injection holes 11 and are internally threadedly connected with plugs 4. The inner end of the plug 4 extends into the injection holes 11. By setting the plugs 4, on the one hand, the injection holes 11 can be blocked, and on the other hand, the reinforcing plate 3 can be initially positioned to facilitate the welding and fixing of the reinforcing plate 3 by workers. The gap between the angle steels 1 and the beam-column is filled with structural grouting adhesive.
[0032] During specific use, for a design reinforcement structure of a building concrete column of the utility model, first place four angle steels 1 at the four edges of the beam column respectively. Then, put the L-shaped butt joint plates 22 and L-shaped connecting plates 21 on the outer sides of the four angle steels 1, and turn the nuts 24 one by one to make the nuts 24 press the L-shaped butt joint plates 22, thereby assembling the L-shaped butt joint plates 22 and L-shaped connecting plates 21 together, and at the same time fixing the four angle steels 1 on the outer side of the beam column. The rubber strips 5 seal the edge gaps of the angle steels 1.
[0033] After that, unscrew the plug 4 at the lowest layer, inject the structural perfusion adhesive into the gap between the angle steel 1 and the beam column through the glue injection hole 11, and finally unscrew the plug 4 layer by layer and inject the structural perfusion adhesive layer by layer.
