DETAILED DESCRIPTION
[0012] The present invention will be further described below with reference to the embodiments and the accompanying drawings.
[0013] Example 1 The process flow of the hidden drainage construction method in the steel structure flower column of the present invention is as follows: Prepare materials (calculate drain pipe length) → insert drain pipe into flower pipe column → weld steel bars to top of drain pipe → hoist as a whole → weld drain pipe → install flower pipe column The method for constructing concealed drainage in a steel structure flower column of the present invention comprises the following steps: (1) Prepare materials (calculate the length of the drainage pipe) Determine the length of the drainage pipe according to the length of the flower pipe column in the design drawing. The length of the drainage pipe exceeds the flower pipe column by 1 meter. Prepare a Φ14*350mm steel bar and two 10# I-beam brackets 4. The I-beam brackets are provided with oblique support rods 6. (2) Insert the drainage pipe into the flower column Please refer to Figure 1 , Figure 1 This is a schematic diagram of the steel structure flower column structure according to an embodiment of the present invention. As shown in the figure, before the flower column is hoisted, a drainage pipe is inserted into the flower column. Figure 2 This is a schematic diagram of the configuration of a drainage pipe inserted into a flower tube column according to an embodiment of the present invention. The drainage pipe is inserted into the flower tube column in the form of: four flower tubes are arranged in a crisscross pattern, and the drainage pipe is inserted into the center of the flower tube column.
[0014] (3) Welding steel bars at the top of the drainage pipe Before hoisting the flower pipe column, weld a Φ14*350mm steel bar 3 20cm below the top of the drainage pipe to support the drainage pipe so that the drainage pipe and the flower pipe column can be hoisted synchronously; the lower end 5 of the drainage pipe exceeds the flower pipe column by 800mm.
[0015] (4) Overall hoisting Row Figure 3 This diagram illustrates the hoisting of a steel structure flower column according to an embodiment of the present invention. After the top steel bars of the water pipe are welded, secure the crane hook to the flower column and slowly lift it. The drain pipe will then rise with it. Position two I-beam supports in the desired position, slowly lower the flower column, and adjust its position so that the drain pipe aligns with the pre-buried drain pipe. Then, slowly place the flower column onto the supports.
[0016] (5) Drain pipe welding After the flower pipe column 2 is placed stably, start welding the stainless steel drainage pipe 1, knock off the welding slag, and apply silver powder paint.
[0017] (6) Installation of flower tube columns After the drainage pipe is completed, remove the I-beam support, continue to lower the flower pipe column and tighten the bolts to complete the hidden drainage construction inside the steel structure flower pipe column.
[0018] The present invention has substantial characteristics and significant technological advancements. The method for constructing hidden drainage in steel structure flower tube columns of the present invention first inserts the drainage pipe into the flower tube column on the ground, welds a 35cm∅14 steel bar on the top of the stainless steel drainage pipe as a support, and the lower end of the drainage pipe extends 800mm beyond the flower tube column, thereby achieving synchronous hoisting of the drainage pipe and the flower tube column. After reaching the designated position, two I-beam brackets are used under the flower tube column for support. After the drainage pipe is welded, the flower tube column continues to descend and install. The method for constructing hidden drainage in steel structure flower tube columns of the present invention effectively solves the technical problems of damaging the drainage pipe when the flower tube column is hoisted later or failing to weld the drainage pipe when the flower tube column is hoisted first, making the construction of the drainage pipe simple and convenient, effectively solving the collision risk generated during the construction process, and ensuring safe and reliable construction.
