Description

Technical Field

[0001] This invention relates to the field of building steel structure processing and fabrication technology, specifically to wall-connecting conversion columns and their manufacturing process. Background Technology

[0002] The Hongqiao Airport T1 Terminal Supporting Business Building Project is located within the Hongqiao T1 terminal area. The site is bordered by the northern boundary of the T1 terminal transportation center to the south, the right-of-way of Airport Road 8 to the east, the T1 terminal energy center to the west, and the T1 terminal A waiting area to the north. The project has a total construction area of ​​46,311.08 m2, with 33,198 m2 above ground and 13,112.88 m2 underground. It has 9 floors above ground and 2 floors underground. The main function of this project is to provide supporting business buildings for the terminal. The above-ground portion includes a public lobby, atrium, restaurants, overnight passenger accommodation, banquet and conference facilities, multi-functional halls, management offices, and administrative offices, among other supporting service facilities. The underground portion mainly consists of logistics service rooms, equipment rooms, and parking garages, with the B2 level parking garage also serving as a civil defense facility.

[0003] There is an underground aviation fuel pipeline on the east side of the site. The basement design must accommodate this pipeline, and the distance between the basement's exterior wall and the pipeline must meet relevant requirements. The basement's exterior wall uses a diaphragm wall system, combining two walls into one. The steel columns on the east side of the basement collide with this diaphragm wall; therefore, the structural design employs a diaphragm wall transfer column approach. Figure 14-17 As shown, the original wall-connecting conversion column was transformed from a cross-shaped box type to a circular pipe connected to the ground wall at an angle. These two transformations made the internal structure of the node very complex. The inner arc plate and the circular pipe correspond perfectly in theory, but it is difficult to actually weld the inner arc plate and the outer curved plate, and the hidden welds of many stiffening plates cannot be welded.

[0004] The method for manufacturing a cross-column to circular tube column structure disclosed in CN107335903B and the cross-column to circular tube column structure therein are straight up and down, and are a single conversion, which will collide with the diaphragm wall of the terminal building's supporting business rooms.

[0005] Therefore, a new technical solution is needed to solve the above-mentioned technical problems. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a wall-connecting conversion column and its manufacturing process that can perfectly realize the wall-connecting conversion and avoid collision between the wall-connecting wall and the steel pipe column, and can easily weld the pistol plate and the outer tile plate, and can also weld the numerous hidden welds of the stiffening plate.

[0007] To solve the above technical problems, the present invention provides a wall-connected conversion column, including a tile plate, a pistol plate, a conversion side plate II, and a cover plate. The pistol plate is set on the tile plate through a sealing plate I and a sealing plate II. On the sealing plate I side, the conversion side plate I is set on the side of the pistol plate that is close to the tile plate, and the conversion side plate I is fixedly connected to a stiffening plate I. A stiffening plate III is set on the pistol plate on the sealing plate II side. A sealing plate III is set at the end of the pistol plate on the sealing plate II side. The conversion side plate II is set on the tile plate. A stiffening plate V is set on the conversion side plate I, and a cross web plate is set on the stiffening plate V. The conversion side plate III and a cross wing plate are set on the side of the conversion side plate I. A cover plate is set on the conversion side plate II and the conversion side plate III, and the cover plate is fixedly connected to the pistol plate. A base plate is set at the end of the pistol plate on the sealing plate I side, and a column top pipe is set on the pistol plate on the sealing plate II side. The column top pipe is connected to the tile plate, and the column top pipe is fixedly connected to the pistol plate and the stiffening plate III.

[0008] By adopting the above technical solution and optimizing the original design structure, the original outer curved plate is split into a U-shaped tile plate plus a conversion side plate II, and the original cross stiffening plate is lifted out. The stiffening plate III and the pistol plate form a cross inserted into the column top tube. The longitudinal conversion main stiffening plate in the intersecting U tube and square tube cavity is merged from the original three plates into a pistol plate, forming a whole plate conversion. The structure is greatly simplified and the force transmission is more direct. Under the premise of ensuring structural strength, the wall-connecting conversion is perfectly realized, avoiding the collision between the ground-connected wall and the steel pipe column.

[0009] Preferably, stiffening plates I are provided on both sides of the pistol plate, and stiffening plates I are fixedly connected to the inner wall of the tile plate. Stiffening plate II is provided on one side of stiffening plate I, and stiffening plate II is fixedly connected to the pistol plate, sealing plate I, and tile plate.

[0010] By adopting the above technical solution, the structural strength is increased by stiffening plate II, which facilitates force transmission.

[0011] Preferably, stiffening plate III is fixedly connected to stiffening plate I and the inner wall of the tile plate.

[0012] Preferably, the conversion side plate II is fixedly connected to the stiffening plate I and the sealing plate III.

[0013] Preferably, stiffening plate V and cross web plate are fixedly connected to pistol plate.

[0014] Preferably, a stiffening plate VI is provided on the cross web, and the stiffening plate VI is fixedly connected to the pistol plate, the conversion side plate II, and the conversion side plate III; the conversion side plate III and the cross wing plate are connected to each other and fixedly connected to the cross web.

[0015] Preferably, the sealing plate III is provided with a groove for engaging with the pistol plate, and the sealing plate III is fixedly connected to the stiffening plate III and the inner wall of the tile plate.

[0016] By adopting the above technical solution, the slot is clamped onto the pistol plate, and then the sealing plate III is welded to the stiffening plate III and the inner wall of the tile plate. The assembly is convenient and the welding is easy.

[0017] Preferably, an internal longitudinal stiffening plate and an external transverse stiffening plate IV are provided between stiffening plate I and sealing plate III.

[0018] By adopting the above technical solution, the structural strength is increased by internal longitudinal and transverse stiffening plates, which facilitates force transmission.

[0019] The manufacturing process of wall-connected transition pipe columns includes the following steps:

[0020] Step 1: Assemble the pistol plate, tile plate, stiffening plate I, and sealing plate I and sealing plate II;

[0021] (1) The welds between stiffening plate I and the wall of the tile plate and the pistol plate shall be welded by single-sided full penetration CJP backing weld;

[0022] The welds between the pistol plate, the sealing plate I, and the tile plate are made using single-sided full penetration CJP backing welds;

[0023] (3) The sealing plate II shall be welded with a single-sided full penetration CJP backing;

[0024] Step 2: First, install and weld the stiffening plate II, then insert the conversion side plate I;

[0025] (1) The weld of stiffening plate II shall be made by single-sided full penetration CJP backing weld;

[0026] (2) Welding of the pistol plate and the conversion side plate I. Note that the bevel of the insertion section is opened on the conversion side plate I, and the single-sided full penetration CJP backing weld is used; the remaining part of the bevel is opened on the pistol plate, and the full penetration CJP root cleaning weld is used.

[0027] Step 3: Install and weld stiffening plate III and sealing plate III in sequence;

[0028] (1) The welds between stiffening plate III and pistol plate, pipe wall and stiffening plate I shall be welded with single-sided full penetration CJP backing;

[0029] (2) The sealing plate III shall be welded by single-sided partial penetration PJP welding; the weld between the pistol plate and the sealing plate III shall be welded by full penetration CJP root cleaning welding;

[0030] Step 4: First install and weld the conversion side plate II, then install and uninstall the internal longitudinal stiffening plate and the outer transverse stiffening plate IV in sequence;

[0031] The welds of the internal longitudinal stiffening plates are welded with full penetration CJP backing; the transverse stiffening plates on the outer side are welded with partial penetration PJP on one side, and the circled area indicates that the outer side is electroslag welded.

[0032] Step 5: Install and weld stiffening plate V and cross web plate in sequence;

[0033] Stiffening plate V is partially fused to PJP on one side;

[0034] (2) The segmented welds of the cross web near the bottom of the column are cleaned by full penetration CJP welding, and the segmented welds in the node area and column are full penetration CJP backing welds.

[0035] Step 6: Sequentially weld the conversion side plate III, the cross wing plate, and the stiffening plate VI;

[0036] The weld of stiffening plate VI is a single-sided partial penetration PJP weld, and the cover plate side is electroslag welded;

[0037] Step 7: Install and weld the cover plate and column top tube. After cutting the column bottom to the specified length, install and weld the column bottom plate. Tear-resistant bevels are made on both the cover plate and the column top tube.

[0038] Preferably, the angle of the tear-resistant bevel is ≥35°, and the width of the tear-resistant bevel of the tension intermediate plate is ≥T / 2+4.

[0039] By adopting the above technical solutions, the tear-resistant bevel further optimizes the structure of the wall-connecting conversion column, improving the stability and reliability of actual welding processing.

[0040] Compared with the prior art, the present invention has the following advantages:

[0041] 1. This invention optimizes the original design structure by splitting the original outer curved plate into a U-shaped tile plate plus a conversion side plate II. The original cross stiffening plate is lifted out. The stiffening plate III and the pistol plate form a cross inserted into the column top tube. The longitudinal conversion main stiffening plate in the intersecting U-tube and square tube cavity is changed from the original three plates to a single pistol plate, forming a whole plate conversion. This simplifies the structure and makes the force transmission more direct. Under the premise of ensuring structural strength, it perfectly realizes the wall-connecting conversion and avoids the collision between the ground-connected wall and the steel pipe column.

[0042] 2. The present invention uses a seven-step sequential assembly and disassembly process for the wall-connected conversion column. First, a single pistol plate is welded onto the tile plate. The original longitudinal conversion main stiffening plate is merged from three pieces into a single pistol plate. The original outer curved plate is split into two parts: the tile plate and the conversion side plate II. This facilitates welding between the pistol plate and the outer tile plate. Then, the stiffening plate and the conversion side plate are welded sequentially. Next, the cross web plate and the cross wing plate are installed. Finally, the cover plate and the column top pipe are welded. Numerous concealed welds on the stiffening plates can also be welded. The assembly and disassembly process is smooth, greatly improving the welding efficiency of the wall-connected conversion column.

[0043] 3. In this invention, the slot is clamped onto the pistol plate, and then the sealing plate III is welded to the stiffening plate III and the inner wall of the tile plate, making assembly convenient and welding easy. Attached Figure Description

The longitudinal transition main stiffening plate in the intersecting U-tube and square tube cavity was originally three plates merged into one pistol plate 2, forming a whole plate transition, which makes the force transmission more direct and efficient. This application greatly simplifies the structure, and while ensuring the structural strength, it perfectly realizes the wall-connecting transition and avoids the collision between the diaphragm wall and the steel pipe column.

[0064] The manufacturing process of wall-connected transition pipe columns includes the following steps:

[0072] (1) The weld of stiffening plate II6 shall be welded by single-sided full penetration CJP backing weld 21;

[0073] (2) Welding of pistol plate 2 and conversion side plate I7. Note that the bevel of the insertion section is opened on the conversion side plate I7, and the single-sided full penetration CJP backing weld 21 is applied; the remaining part of the bevel is opened on pistol plate 2, and the full penetration CJP root cleaning weld 20 is applied.

[0074] Step 3: Press Figure 7 Stiffening plate Ⅲ8 and sealing plate Ⅲ9 are welded in sequence;

[0077] Step 4: Press Figure 8 First, install and weld the conversion side plate II10, then install and uninstall the internal longitudinal stiffening plate and the outer transverse stiffening plate IV11 in sequence.

[0078] (1) The weld of the internal longitudinal stiffening plate is welded with full penetration CJP backing weld 21, and pay attention to back welding; the outer transverse stiffening plate Ⅳ11 is welded with single-sided partial penetration PJP, and the circle indicates that the outer side is electroslag welded.

[0079] Step 5: Press Figure 9 Stiffening plate V13 and cross web plate 12 are welded in sequence;

[0080] (1) The stiffening plate V13 is partially melted through PJP on one side; the two stiffening plates V13 at the left end of the conversion side plate II10 can be appropriately moved to the left by 5mm.

Note that according to Figure 13 The tear-resistant bevel shall be opened. The width of the tear-resistant bevel shall not be less than T / 2+4; T is the thickness of the pistol plate 2 or the thickness of the stiffening plate III 8. If the thickness of the tension intermediate plate cannot meet the tear-resistant bevel angle requirements, ensure that the remaining blunt edge is at least 10mm, and then open a bevel on the corresponding cover plate 17 or column top pipe 19.

[0086] After structural optimization, this application employs a seven-step sequential assembly and disassembly process. First, a single pistol plate 2 is welded onto the tile plate 1. The original longitudinal transition main stiffening plate, consisting of three pieces, is merged into a single pistol plate 2. The original outer curved plate is split into two parts: the tile plate 1 and the transition side plate II 10. This facilitates welding between the pistol plate 2 and the outer tile plate 1. Then, the stiffening plate and the transition side plate are welded sequentially. Next, the cross web plate 12 and the cross wing plate 15 are installed. Finally, the cover plate 17 and the column top pipe 19 are welded. Numerous concealed welds on the stiffening plates can also be welded. The assembly and disassembly process is smooth, greatly improving the welding efficiency of the wall-connected transition pipe column.
