Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a construction method for steel structure hoisting tracks used in curtain wall engineering. Background Technology

[0002] Currently, an increasing number of high-rise buildings are using steel structures for their rooftop structures. The finished facade of the building is no longer the conventional parapet wall on the roof, but rather a steel frame structure that extends above the roof. This presents certain challenges to the construction of the building's exterior facade.

[0003] In existing technologies, tower cranes and other vertical transportation tools are usually dismantled during the curtain wall construction phase. Currently, the installation of curtain wall materials above the roof steel structure frame is mainly done using truck cranes. However, as building height increases, the lifting capacity of the truck cranes required also increases, resulting in a significant increase in construction costs. Summary of the Invention

[0004] The purpose of this invention is to provide a construction method for steel structure hoisting tracks used in curtain wall engineering, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a construction method for a steel structure hoisting track for curtain wall engineering, comprising the following specific steps: S1: Construction material preparation: 22# I-beams commonly used in construction engineering are used as columns, 16# I-beams as track beams and cantilever beams, square steel pipes as diagonal braces, and steel plates are processed into U-shaped supports, which also serve as connecting steel plates between cantilever beams and track beams and between cantilever beams and columns. Bolts are used to pass through the steel plates, and top screws are used to fix the lower steel beams. S2: Machining U-shaped supports, welding U-shaped supports from steel plates; S3: The support is fixed to the steel structure, and the U-shaped support is fixed to the steel beam of the roof steel structure. The processed U-shaped support is put into the steel structure beam and fixed with bolts, while tightening with set screws. S4: Column and support fixation: Fully weld the 22# I-beam to the U-shaped support and add a rib on each side. Alternatively, the U-shaped support can be omitted, and the column can be directly welded to the steel structure beam. After dismantling, the steel structure beam needs to be derusted and repainted. S5: The column is connected to the cantilever beam by welding a steel plate to the upper end of the 22# I-beam and the lower end of the cantilever beam, and then fixing them with bolts; S6: The track beam is fixed to the cantilever steel beam. A steel plate is welded to the lower part of the outer end of the cantilever steel beam. A steel plate is welded to each end of the track steel beam joint. Bolts are used to fix it to the cantilever steel beam. At the same time, channel steel is used to connect adjacent columns. S7: After all components are installed, the construction personnel will inspect and accept the completed steel structure. After acceptance, the staff will install the electric hoist on the track beam.

[0006] Preferably, in step S1, each of the 22# I-beams is fixedly installed with a U-shaped support at its bottom end. The U-shaped supports are fixedly installed on the steel beam of the steel structure by bolts. Each of the U-shaped supports has multiple evenly distributed nut seats fixedly installed at its bottom end. Each nut seat has a set screw threaded into it. Ribs are fixedly installed at the contact position between the bottom end of the 22# I-beam and the U-shaped support.

[0007] Preferably, a 16# I-beam is fixedly installed on the top of each 22# I-beam, and square steel pipes are fixedly installed on both sides of the bottom of each 16# I-beam. The bottom of one side of the square steel pipe is fixedly installed on a U-shaped support, and the bottom of the other side of the square steel pipe is fixedly installed on the 22# I-beam.

[0008] Preferably, a 200H-beam is fixedly installed on the other side of the bottom end of the 16# I-beam, an electric hoist is slidably installed on the 200H-beam, and a channel steel is fixedly installed on the top of the adjacent 16# I-beam.

[0009] Preferably, a buffer assembly is installed on the square steel tube on the other side. The buffer assembly includes an upper mounting base, a rod sleeve, a top rod, a spring one, a baffle, a lower mounting base, an adjusting nut, a spring two, and a limiting plate.

[0010] Preferably, the upper mounting bases are all fixedly installed on the lower surface of the 16# I-beam, and the lower part of each upper mounting base is rotatably installed with a sleeve. A top rod is slidably connected inside each sleeve. A lower mounting base is rotatably installed at the end of each top rod away from the sleeve.

The end of the spring away from the rod sleeve is fixedly mounted on the side of the baffle away from the adjusting nut. The end of the spring away from the baffle is fixedly mounted on the lower part of the rod sleeve.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention solves the problems of erecting tracks for roof steel structure layers and hoisting curtain walls. Based on the needs of the construction site and combined with actual construction experience, it provides a track hoisting device that can transport vertically and move horizontally, thereby improving work efficiency and reducing construction costs.

[0014] 2. By setting up a buffer assembly, the rod sleeve inside the buffer assembly, together with the top rod, spring one and spring two, can correspondingly offset the pressure borne by the square steel pipe, thereby protecting the square steel pipe and preventing it from being subjected to excessive pressure, which could lead to deformation of the square steel pipe and cause safety accidents. At the same time, it helps to ensure the stability of the overall structure and ensures that the electric hoist can stably lift the building curtain wall. Attached Figure Description

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1 to 6 This invention provides a technical solution: a construction method for steel structure hoisting tracks used in curtain wall engineering, comprising the following specific steps: S1: Construction material preparation: 22# I-beam 12 commonly used in construction engineering is used as the column, 16# I-beam 4 is used as the track beam and cantilever steel beam, square steel pipe 3 is used as the diagonal brace, steel plate is processed into U-shaped support 9, which also serves as the connecting steel plate between the cantilever steel beam and the track steel beam and between the cantilever steel beam and the column, bolt 8 passes through the steel plate, and set screw 11 fixes the lower steel beam; In step S1, the steel pipe 3 has a specification of 120×60×5mm, the steel plate between the cantilever steel beam and the track steel beam has a specification of 14mm, the U-shaped support 9 is made of 16mm steel plate welded together, the steel plate between the cantilever steel beam and the column has a specification of 12mm, and the steel structure beam has a specification of 350*350mm.

[0019] S2: Machining U-shaped support 9, welding steel plate to machine U-shaped support 9; S3: The support is fixed to the steel structure. The U-shaped support 9 is fixed to the steel beam 1 of the roof steel structure. The processed U-shaped support 9 is put into the steel structure beam and fixed with bolts 8. At the same time, the set screws 11 are used to tighten it. In step S3, bolt 8 is an M25 bolt that passes through the steel plate, and set screw 11 is an M16 bolt.

[0020] S4: Column and support fixation: Fully weld 22# I-beam 12 to U-shaped support 9 and add one rib plate 2 on each side. Alternatively, the U-shaped support 9 can be omitted, and the column can be directly welded to the steel structure beam 1. After removal, the steel structure beam 1 needs to be rust-removed and repainted. S5: The column is connected to the cantilever beam by welding a steel plate to the upper end of the 22# I-beam 12 and the lower end of the cantilever beam, and then fixing it with bolt 8; S6: The track beam is fixed to the cantilever steel beam. A steel plate is welded to the lower part of the outer end of the cantilever steel beam. A steel plate is welded to each end of the track steel beam joint. Bolts 8 are used to fix it to the cantilever steel beam. At the same time, the adjacent columns are connected by channel steel. In step S6, M12 high-strength bolts are used, the steel plate is 240*310*12mm, and the channel steel is 10# channel steel to increase the overall structural stability.

[0021] S7: After all components are installed, the construction personnel will inspect and accept the completed steel structure. After acceptance, the staff will install the electric hoist 7 on the track beam.

[0022] In step S1, U-shaped supports 9 are fixedly installed at the bottom of each 22# I-beam 12. Each U-shaped support 9 is fixedly installed on the steel beam 1 of the steel structure by bolts 8. Multiple evenly distributed nut seats 10 are fixedly installed at the bottom of each U-shaped support 9. Each nut seat 10 is threaded with a set screw 11. Ribs 2 are fixedly installed at the contact positions between the bottom of the 22# I-beam 12 and the U-shaped support 9. By setting the ribs 2, the connection stability between the 22# I-beam 12 and the U-shaped support 9 can be increased. At the same time, the set screw 11 and the bolts 8 cooperate with each other to ensure the connection stability between the U-shaped support 9 and the steel beam 1 of the steel structure, and prevent the overall structure from loosening and shaking.

[0023] Each of the 22# I-beams 12 has a 16# I-beam 4 fixedly installed at its top. Square steel pipes 3 are fixedly installed on both sides of the bottom of each 16# I-beam 4. These square steel pipes 3 act as diagonal supports, effectively reducing the stress on the columns and preventing damage and accidents caused by excessive stress during the hoisting process. The bottom of one side of the square steel pipe 3 is fixedly installed on a U-shaped support 9, and the bottom of the other side is fixedly installed on the 22# I-beam 12. A 200H-beam 6 is fixedly installed on the other side of the bottom of each 16# I-beam 4. An electric hoist 7 is slidably installed on the 200H-beam 6. Channel steel is fixedly installed at the top of each adjacent 16# I-beam 4. The channel steel increases the overall structural stability, ensuring the electric hoist 7 can stably hoist the building curtain wall.

[0024] On the other side, each square steel pipe 3 is equipped with a buffer assembly 5. The buffer assembly 5 includes an upper mounting base 51, a sleeve 52, a top rod 53, a spring 54, a baffle 55, a lower mounting base 56, an adjusting nut 57, a spring 58, and a limiting plate 59. The upper mounting base 51 is fixedly installed on the lower surface of the 16# I-beam 4. A sleeve 52 is rotatably installed on the lower part of each upper mounting base 51. A top rod 53 is slidably connected inside each sleeve 52. A lower mounting base 56 is rotatably installed on the end of the top rod 53 away from the sleeve 52. The lower mounting base 56 is fixedly installed on the surface of the square steel pipe 3 on the other side. By setting up the buffer assembly 5, when the square steel pipe 3 on the side closer to the electric hoist 7 is subjected to a large tensile force, the sleeve 52, in conjunction with the top rod 53, spring 54, and spring 58, can correspondingly reduce the pressure on the square steel pipe 3, thus preventing deformation of the square steel pipe 3 and the occurrence of safety accidents that could harm the personal safety of construction personnel. Limiting plates 59 are fixedly installed at the end of the top rod 53 away from the lower mounting base 56. The limiting plates 59 are slidably installed inside the rod sleeve 52. A second spring 58 is fixedly installed on the side of the limiting plate 59 away from the top rod 53. The end of the second spring 58 away from the limiting plate 59 is fixedly installed at the top of the rod sleeve 52. A baffle 55 is slidably installed on the lower part of the outer periphery of the top rod 53. An adjusting nut 57 is rotatably installed on the lower part of the baffle 55. The adjusting nut 57 is threaded to the outer periphery of the top rod 53. A first spring 54 is fixedly installed on the side of the baffle 55 near the rod sleeve 52. The end of the first spring 54 away from the rod sleeve 52 is fixedly installed on the side of the baffle 55 away from the adjusting nut 57. The end of the first spring 54 away from the baffle 55 is fixedly installed at the lower part of the rod sleeve 52. By setting the adjusting nut 57, the elastic force of the first spring 54 can be changed, thereby correspondingly offsetting the stress borne by the square steel pipe 3, which is conducive to ensuring the stability of the overall structure.

[0025] In actual use, construction workers use 22# I-beams (12) commonly used in building construction as columns, 16# I-beams (4) as track beams and cantilever beams, square steel pipes (3) as diagonal braces, and U-shaped supports (9) made of steel plates, according to construction requirements. After the installation of each component is completed, the construction workers inspect and accept the installed steel structure. After acceptance, the construction workers install electric hoists (7) on the track beams. Then, the construction workers can use electric hoists (7) to lift and transport the building curtain wall. During the lifting, the rod sleeves (52) in the buffer component (5), together with the top rods (53), spring one (54), and spring two (58), can reduce the pressure on the square steel pipes (3) and prevent deformation of the square steel pipes (3).
