[0014] The present invention will be further described in detail below with reference to the accompanying drawings.

[0015] like Figure 1 , Figure 2 As shown, a waterproof connection node structure between concrete and steel column includes a concrete base slab 1, a steel structure column 2, a non-curing rubber asphalt waterproof coating layer 3, a waterproof jacket 4, and a waterproof membrane 5.

[0016] like Figure 1 , Figure 2As shown, the concrete base slab 1 is set horizontally, the steel structure column 2 is set vertically on the concrete base slab 1 and the lower end is embedded in the concrete base slab 1, and the non-curing rubber asphalt waterproof coating layer 3 is applied to the outside of the connection position between the concrete base slab 1 and the steel structure column 2.

[0017] like Figure 1 , Figure 2 As shown, the waterproof jacket 4 is fitted onto the lower outer wall of the steel structure column 2, and the waterproof membrane 5 is wrapped around the connection between the concrete base slab 1 and the steel structure column 2, and also covers the waterproof jacket 4.

[0018] like Figure 3 As shown, the waterproof jacket 4 includes a sleeve 41, a pressure ring 42, and a connector 6. The sleeve 41 is C-shaped and interlocks with each other. The pressure ring 42 is horizontally positioned at the lower end of the sleeve 41 and presses against the concrete base plate 1. Steel pads 43 are embedded at the corners of both the sleeve 41 and the pressure ring 42 to abut against the four corners of the steel structure column 2, preventing damage at the corners.

[0019] like Figure 3 As shown, the upper end of the sleeve 41 and the outer edge of the pressure ring 42 are both set with bevels, so that the two ends of the waterproof membrane 5 are bonded to the concrete base slab 1 and the steel structure column 2 in a transitional manner, thereby increasing stability.

[0020] like Figure 3 As shown, the connector 6 is disposed between the sleeve 41 and the pressure ring 42, and is used to fix a pair of sleeves 41 and pressure rings 42. The connector 6 includes an insert 61 and a slot 62. The insert 61 is disposed at one end of the sleeve 41 and the pressure ring 42, and the slot 62 is disposed at the other end of the sleeve 41 and the pressure ring 42, and is used for inserting the insert 61.

[0021] like Figure 3 As shown, both sides of the insert 61 are provided with locking teeth 63, and the inner wall of the slot 62 is provided with a locking groove 64 for the locking teeth 63 to be inserted, so as to increase the stability between the two. The outer wall of the sleeve 41 is provided with a pull tab 45 for tightening and fixing during fastening.

[0022] When waterproofing is required at the connection point between the concrete base slab 1 and the steel structure column 2, the non-curing rubber asphalt waterproof coating layer 3 is first applied to the outside of the connection point between the concrete base slab 1 and the steel structure column 2 to seal the gap.

[0023] Then, the waterproof sleeve 4 is taken out, structural adhesive is applied to the inside of the waterproof sleeve 4, and the waterproof sleeve 4 is fastened to the outer wall of the steel structure column 2. Then, the pull tab 45 is pulled to bring a pair of sleeves 41 closer to each other, so that the insert 61 and the slot 62 are inserted into each other, and the entire waterproof sleeve 4 is fixed under the cooperation of the locking teeth 63 and the locking groove 64.

[0024] Then, the outer wall of the waterproof jacket 4 is tapped to bond and fix the sleeve 41 and the pressure ring 42 to the concrete column and the concrete base plate 1 respectively, so as to achieve the wrapping and sealing of the connection position between the concrete base plate 1 and the steel structure column 2. At the same time, the waterproof jacket 4 can automatically form a seal to ensure the waterproof performance of the connection node.

[0025] Finally, the waterproof membrane 5 is wrapped around the connection between the concrete base slab 1 and the steel structure column 2, and the waterproof membrane 5 is wrapped around the waterproof jacket 4 to achieve secondary waterproof sealing at the connection node between the concrete base slab 1 and the steel structure column 2. Finally, a layer of waterproof mortar is applied to the outside of the waterproof membrane 5 to complete the waterproofing project.

[0026] Therefore, by applying a non-curing rubber asphalt waterproof coating layer 3 at the connection node and setting a waterproof jacket 4 at the root of the connection node, the connection between the concrete and the steel column is tightened and sealed. At the same time, a waterproof membrane 5 is wrapped on the outside to achieve waterproof sealing of the connection node between the concrete and the steel column, avoid leakage, and improve waterproof performance.
