Description

Technical Field

[0001] This application relates to the field of steel structure buildings, and in particular to a prefabricated steel structure residential building and its construction process. Background Technology

[0002] Steel structure housing refers to residential buildings that use steel as the load-bearing beams and columns. The advantages of steel structure houses include light weight and high strength. The weight of a house built with steel structure is about half that of a reinforced concrete house, which can meet the needs of large open space and increase the usable area by about 4% compared with reinforced concrete houses. At the same time, steel structure components are manufactured in factories, reducing on-site work, shortening the construction period, meeting the requirements of industrialization, and steel can be recycled, resulting in less environmental pollution during construction and demolition.

[0003] A steel structure house typically consists of a foundation, steel structure support columns, steel structure support beams, and various steel structure connecting rods. The steel structure support columns and steel structure support beams are the main supporting structures of a steel structure house. During construction, the corresponding steel structure support columns are usually erected first according to the drawings. Then, the steel structure support beams are moved between adjacent steel structure support columns using hoisting equipment and then fixed in place using fasteners.

[0004] When fixing a steel structure support beam between adjacent steel structure support columns, both the support beam and the support column are typically made of I-beams. T-shaped fasteners are fixed to the support columns, with the bottom of the T-shaped fasteners attached to the support columns. Then, the support beam is lifted using hoisting equipment, positioned between adjacent support columns, and aligned with the T-shaped fasteners. The support beam is then moved laterally, allowing the T-shaped fasteners to enter the grooves in the support beam. Fastening bolts are then used to secure the beam by passing through the T-shaped fasteners and the support beam. To facilitate easy insertion of the T-shaped fasteners into the grooves, the T-shaped fasteners are made slightly smaller than the grooves in the support beam. This can lead to misalignment between the fixing holes on the T-shaped fasteners and the fixing holes on the support beam when the T-shaped fasteners are inserted into the grooves, making subsequent bolt insertion more difficult. Summary of the Invention

[0005] The purpose of this application is to address the problem mentioned in the background art that, in order to facilitate the T-shaped fastener entering the groove of the support beam, the T-shaped fastener needs to be smaller than the groove of the support beam. This results in the possibility that the fixing holes on the T-shaped fastener and the fixing holes on the support beam may not align when the T-shaped fastener enters the groove of the support beam, making it more difficult to insert the fixing bolts later. This application provides a prefabricated steel structure residential building and its construction process.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] A prefabricated steel structure residential building includes several I-beam columns, with I-beam beams arranged between adjacent I-beam columns. T-shaped fasteners are fixed on the I-beam columns, and an abutment positioning mechanism is provided between the T-shaped fasteners and the I-beam beams. An auxiliary positioning mechanism is provided on the T-shaped fasteners.

[0008] By adopting the above technical solution, the I-beam is hoisted onto the side of the T-shaped fastener on two I-beam columns using hoisting equipment. Then, the I-beam is moved towards the T-shaped fastener, allowing the T-shaped fastener to enter the groove of the I-beam. During the movement, the I-beam presses against the positioning mechanism, which simultaneously supports the inner wall of the groove of the I-beam, positioning the T-shaped fastener in the middle of the groove. At the same time, the fixing mechanism drives the auxiliary positioning mechanism, which laterally positions the I-beam, aligning the fixing holes on the T-shaped fastener with the fixing holes on the I-beam. This ensures that as the I-beam moves closer to the T-shaped fastener, the fixing holes on the I-beam align with those on the T-shaped fastener, facilitating the insertion of fixing bolts through the I-beam and the T-shaped fastener.

[0009] Furthermore, the abutment positioning mechanism includes an abutment block disposed on the T-shaped fastener, the abutment block being located on the side of the T-shaped fastener facing the I-beam, two symmetrical support blocks being disposed on the T-shaped fastener, an opening component being disposed between the abutment block and the two support blocks, and a one-way movement component being disposed between the abutment block and the T-shaped fastener.

[0010] By adopting the above technical solution, when the I-beam approaches the T-shaped fastener, the I-beam presses against the contact block, the contact block drives the opening component, and the opening component drives the two support blocks, so that the two support blocks simultaneously abut against the inner wall of the groove of the I-beam, so that the T-shaped fastener is located in the middle of the groove of the I-beam. This makes it easy to align the fixing holes on the I-beam with the fixing holes on the T-shaped fastener, making it easy to pass the fixing bolts through.

[0011] Furthermore, the opening assembly includes two sliding blocks symmetrically arranged on a T-shaped fixing member. The T-shaped fixing member has a sliding groove, and the sliding blocks are located in the sliding groove and slidably connected to the T-shaped fixing member. The two sliding blocks are fixedly connected to corresponding support blocks. A support rod is provided between the two sliding blocks. The support rod passes through the T-shaped fixing member and is slidably connected to the T-shaped fixing member. One end of the support rod is fixedly connected to an abutment block. A connecting rod is provided between the support rod and the sliding blocks. Both ends of the connecting rod are rotatably connected to the support rod and the sliding blocks.

[0012] By adopting the above technical solution, when the I-beam approaches the T-shaped fastener, the I-beam presses against the contact block, the contact block drives the support rod, and the support rod drives the sliding block through the connecting rod, so that the two sliding blocks drive the support block, thereby making it easy for the support block to simultaneously abut against the inner wall of the groove of the I-beam.

[0013] Furthermore, a limit spring is provided between the end of the support rod away from the contact block and the T-shaped fixing member, and both ends of the limit spring are fixedly connected to the support rod and the T-shaped fixing member.

[0014] By adopting the above technical solution, under the restriction of the limiting spring, the end of the support rod with the abutment block is kept in the state of extending out of the T-shaped fixing piece, so that when the I-beam squeezes the abutment block, the connecting block drives the sliding block, and the sliding block drives the support block to extend.

[0015] Furthermore, the unidirectional moving component includes a first snap-fit ​​block disposed on a support rod, the first snap-fit ​​block being slidably connected to the support rod, and a plurality of support springs being disposed between the support rod and the first snap-fit ​​block, both ends of the support springs being fixedly connected to the first snap-fit ​​block and the support rod, a second snap-fit ​​block being disposed on one side of the first snap-fit ​​block, the second snap-fit ​​block being fixedly connected to a T-shaped fastener, and snap-fit ​​teeth being provided on both the first snap-fit ​​block and the second snap-fit ​​block, with the snap-fit ​​teeth on the first snap-fit ​​block and the second snap-fit ​​block facing opposite directions.

[0016] By adopting the above technical solution, the support rod slides on the T-shaped fastener. When the I-beam and the T-shaped fastener are completely in contact, the support rod stops moving. Under the push of the support spring, the first and second locking blocks are locked together, thus enabling the support rod to remain stable when it extends.

[0017] Furthermore, the auxiliary positioning mechanism includes an inclined block disposed on a T-shaped fixing member, the inclined surface of the inclined block facing the support rod and abutting against the support rod, a support assembly disposed between the inclined block and the T-shaped fixing member, a cone head fixed on the inclined block, and a positioning groove provided on the I-beam, the end of the positioning groove facing the cone head being open.

[0018] By adopting the above technical solution, while the support rod pushes the support block out, the support rod abuts against the inclined surface of the inclined block, allowing the inclined block to slide under the support of the support assembly. This allows the inclined block to drive the cone head to insert into the positioning groove of the I-beam, thereby further aligning the fixing holes on the T-shaped fastener with the fixing holes on the I-beam, making it easier for the fixing bolts to pass through the I-beam and the T-shaped fastener.

[0019] Furthermore, the support assembly includes a support frame fixed to a T-shaped fastener, the inclined block passes through the support frame, and limit blocks are fixed on both sides of the inclined block, with the limit blocks slidably connected to the support frame.

[0020] By adopting the above technical solution, the tilting block slides under the limit of the support frame, while the limit block restricts the tilting block, thereby enabling the tilting block to stably drive the cone head to move.

[0021] A construction process for prefabricated steel structure residential buildings, applicable to any of the aforementioned prefabricated steel structure residential buildings, wherein the construction process is as follows:

[0022] S1: When it is necessary to trim the steel structure house, first trim the foundation according to the steel structure house drawings and determine the position of several I-beam columns.

[0023] S2: Then, embed the corresponding fixing bolts at the fixed position of the I-beam column in the foundation. Then, use hoisting equipment to lift the I-beam column to the position of the fixing bolts. Then, press the I-beam column against the foundation. Then, use the fixing bolts to fix the I-beam column to the foundation. Then, use the fixing bolts to fix the T-shaped fasteners on the I-beam column.

[0024] S3: Then, use hoisting equipment to lift the I-beam between the adjacent I-beam columns, making the I-beam flush with the T-shaped fasteners on the adjacent I-beam columns. Then, move the I-beam closer to the T-shaped fasteners, so that the fixing surface on the T-shaped fasteners contacts the I-beam. At the same time, the I-beam presses against the contact block, the contact block pushes the support rod, the support rod drives the connecting rod, the connecting rod drives the sliding block, and the sliding block drives the support block to extend out of the T-shaped fastener.

[0025] S4: Two support blocks extending from the T-shaped fastener simultaneously abut against the groove sidewall of the I-beam, aligning the fixing holes on the I-beam with the fixing holes on the T-shaped fastener.

[0026] S5: While the I-beam pushes the support rod, the support rod pushes the tilting block, which, under the constraint of the support frame, drives the cone head. The cone head is inserted into the positioning groove on the I-beam. Under the constraint of the inclined surface of the cone head, the fixing hole on the I-beam is horizontally aligned with the fixing hole on the T-shaped fastener. Then, the construction workers use fixing bolts to pass through the T-shaped fastener and the I-beam to fix it, thus completing the connection between the I-beam column and the I-beam.

[0027] In summary, this application includes at least one of the following beneficial effects;

[0028] 1. In this application, during the installation of the I-beam, a hoisting device is used to lift the I-beam onto the side of a T-shaped fastener on two I-beam columns. The I-beam is then moved towards the T-shaped fastener, allowing it to enter the groove of the I-beam. During this movement, the I-beam presses against abutting blocks, which, supported by a support rod, move closer to the T-shaped fastener. The support rod then drives a connecting rod, which in turn drives a sliding block, causing the two sliding blocks to move away from each other. These two sliding blocks then drive a support block, causing both support blocks to simultaneously abut against the inner wall of the groove in the I-beam, positioning the T-shaped fastener in the middle of the I-beam. As the beam approaches the T-shaped fastener and presses against the contact block, the support rod pushes the support block out while simultaneously contacting the inclined surface of the tilting block. This allows the tilting block to slide under the support of the support assembly, causing the tilting block to drive the cone head into the positioning groove of the I-beam. When the I-beam deviates, the inclined surface of the cone head contacts the edge of the positioning groove, allowing the I-beam to adjust laterally and align with the fixing holes on the T-shaped fastener. This achieves the goal of aligning the fixing holes on the I-beam with those on the T-shaped fastener as the I-beam moves closer to it, facilitating the insertion of fixing bolts through the I-beam and the T-shaped fastener.

[0029] 2. In this application, when the I-beam is pressed against the contact block, the contact block presses against the support rod, causing the support rod to slide on the T-shaped fixing member. Then, the support rod drives the locking block one, and the locking teeth on the locking block one abut against the inclined surface of the locking teeth on the locking block two. Then, the locking block one slides on the support rod and compresses the support spring, allowing the support rod to slide. When the I-beam and the T-shaped fixing member are completely in contact, the support rod stops moving. Under the push of the support spring, the locking block one and the locking block two are locked together, thus achieving the purpose of maintaining stability when the support rod drives the support block to extend.

[0030] 3. In this application, when the I-beam is not pressing against the abutment block, the end of the support rod with the abutment block fixed to it is kept extended out of the T-shaped fixing member under the restriction of the limiting spring. The connecting rod drives the support block to be kept retracted into the T-shaped fixing member. By using the limiting spring to limit the support rod, it is possible to keep the end of the support rod with the abutment block fixed to it extended. This facilitates the purpose of allowing the connecting block to drive the sliding block when the I-beam presses against the abutment block, and then allowing the sliding block to drive the support block to extend.

[0038] The following is in conjunction with the appendix Figure 1 —5 provides further detailed description of this application.

[0039] This application discloses a prefabricated steel structure residential building and its construction process.

[0040] Reference Figure 1 , Figure 2 and Figure 3 A prefabricated steel structure residential building includes several I-beam columns 1, I-beam beams 2 are arranged between adjacent I-beam columns 1, T-shaped fasteners 3 are fixed on the I-beam columns 1, an abutment positioning mechanism 4 is arranged between the T-shaped fasteners 3 and the I-beam beams 2, and an auxiliary positioning mechanism 5 is arranged on the T-shaped fasteners 3.

[0041] When constructing a steel structure house, the foundation is first prepared according to the blueprints, determining the positions of several I-beam columns 1. Then, corresponding fixing bolts are pre-embedded at the positions where the I-beam columns 1 are fixed in the foundation. Next, hoisting equipment is used to lift the I-beam columns 1 to the positions of the fixing bolts. The I-beam columns 1 are then pressed against the foundation, and the fixing bolts are used to secure them. T-shaped fasteners 3 are then fixed to the I-beam columns 1 using the fixing bolts. When installing the I-beam beam 2, hoisting equipment is used to lift the I-beam beam 2 to the side of the T-shaped fasteners 3 on the two I-beam columns 1. The I-beam beam 2 is then moved towards the T-shaped fasteners 3, allowing the T-shaped fasteners 3 to enter the grooves of the I-beam beam 2. During this movement, the I-beam beam 2 presses against the positioning mechanism 4, which simultaneously supports the inner wall of the groove, positioning the T-shaped fasteners 3 in the middle of the groove, ensuring that the fixing holes on the T-shaped fasteners 3 align with the I-beam beam 2. The fixing holes on the I-beam 2 are aligned vertically. While the I-beam 2 presses against the positioning mechanism 4, the fixing mechanism drives the auxiliary positioning mechanism 5. The auxiliary positioning mechanism 5 performs lateral positioning of the I-beam 2, aligning the fixing holes on the T-shaped fastener 3 with the fixing holes on the I-beam 2. Then, fixing bolts are passed through the fixing holes on the I-beam 2 and the T-shaped fastener 3 for fixing. As the I-beam 2 moves towards the T-shaped fastener 3, and the T-shaped fastener 3 supports the I-beam 2, the I-beam 2 presses against the positioning mechanism 4 on the T-shaped fastener 3. The positioning mechanism 4 limits the movement of the I-beam 2. At the same time, the positioning mechanism 4 drives the auxiliary positioning mechanism 5, which further limits the movement of the I-beam 2. This allows the fixing holes on the I-beam 2 to align with the fixing holes on the T-shaped fastener 3 when the I-beam 2 moves closer to the T-shaped fastener 3, making it easier to pass the fixing bolts through the I-beam 2 and the T-shaped fastener 3.

[0042] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5 The contact positioning mechanism 4 includes a contact block 41 disposed on the T-shaped fastener 3. The contact block 41 is located on the side of the T-shaped fastener 3 facing the I-beam 2. Two symmetrical support blocks 42 are disposed on the T-shaped fastener 3. An opening component 43 is disposed between the contact block 41 and the two support blocks 42. A one-way moving component 44 is disposed between the contact block 41 and the T-shaped fastener 3.

[0043] When the I-beam 2 is moved between the two I-beam columns 1 using hoisting equipment, the side of the I-beam 2 moves towards the T-shaped fastener 3 on the I-beam column 1. As the I-beam 2 approaches the T-shaped fastener 3, it presses against the contact block 41. The contact block 41 drives the opening component 43, which in turn drives the two support blocks 42. Simultaneously, the one-way moving component 44 limits the opening component 43, causing the two support blocks 42 to simultaneously abut against the inner wall of the groove in the I-beam 2. This positions the T-shaped fastener 3 in the middle of the groove in the I-beam 2. The fixing holes on T-shaped fastener 3 are aligned with the fixing holes on I-beam 2. Then, the fixing bolts are passed through the fixing holes on T-shaped fastener 3 and I-beam 2. When I-beam 2 moves closer to T-shaped fastener 3, it presses against the contact block 41. The contact block 41 drives the opening component 43. The opening component 43 drives the two support blocks 42 to support the groove of the contacting I-beam 2 at the same time, so that T-shaped fastener 3 is located in the middle of I-beam 2. This makes it easy to align the fixing holes on I-beam 2 with the fixing holes on T-shaped fastener 3, and makes it easy to pass the fixing bolts through.

[0044] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5 The opening component 43 includes two sliding blocks 433 symmetrically arranged on the T-shaped fixing member 3. The T-shaped fixing member 3 has a sliding groove 434. The sliding blocks 433 are located in the sliding groove 434 and are slidably connected to the T-shaped fixing member 3. The two sliding blocks 433 are fixedly connected to the corresponding support blocks 42. A support rod 431 is provided between the two sliding blocks 433. The support rod 431 passes through the T-shaped fixing member 3 and is slidably connected to the T-shaped fixing member 3. One end of the support rod 431 is fixedly connected to the abutment block 41. A connecting rod 432 is provided between the support rod 431 and the sliding blocks 433. Both ends of the connecting rod 432 are rotatably connected to the support rod 431 and the sliding blocks 433.

[0045] When the I-beam 2 moves closer to the T-shaped fastener 3, the I-beam 2 presses against the contact block 41. The contact block 41 moves closer to the T-shaped fastener 3 under the support of the support rod 431. Then, the support rod 431 drives the connecting rod 432, and the connecting rod 432 drives the sliding block 433, causing the two sliding blocks 433 to move away from each other. Then, the two sliding blocks 433 drive the support block 42, causing the two support blocks 42 to simultaneously abut against the inner wall of the groove of the I-beam 2. By pressing the contact block 41 with the I-beam 2, the contact block 41 moves under the support of the support rod 431. Then, the support rod 431 drives the connecting rod 432, and the connecting rod 432 simultaneously drives the two sliding blocks 433, thus making it convenient for the support blocks 42 to simultaneously abut against the inner wall of the groove of the I-beam 2.

[0046] Reference Figure 3and Figure 5 A limit spring 435 is provided between the end of the support rod 431 away from the contact block 41 and the T-shaped fixing member 3. Both ends of the limit spring 435 are fixedly connected to the support rod 431 and the T-shaped fixing member 3.

[0047] When the I-beam 2 is not pressing against the contact block 41, under the restriction of the limiting spring 435, the end of the support rod 431 with the contact block 41 is kept extending out of the T-shaped fixing member 3, and the connecting rod 432 drives the support block 42 to be kept retracted into the T-shaped fixing member 3. By using the limiting spring 435 to limit the support rod 431, it is easy to keep the end of the support rod 431 with the contact block 41 in an extended state. When the I-beam 2 presses against the contact block 41, the connecting block drives the sliding block 433, and the sliding block 433 drives the support block 42 to extend.

[0048] Reference Figure 3 and Figure 5 The unidirectional moving component 44 includes a first snap-fit ​​block 441 disposed on the support rod 431. The first snap-fit ​​block 441 is slidably connected to the support rod 431. A plurality of support springs 443 are disposed between the support rod 431 and the first snap-fit ​​block 441. Both ends of the support springs 443 are fixedly connected to the first snap-fit ​​block 441 and the support rod 431. A second snap-fit ​​block 442 is disposed on one side of the first snap-fit ​​block 441. The second snap-fit ​​block 442 is fixedly connected to the T-shaped fastener 3. Both the first snap-fit ​​block 441 and the second snap-fit ​​block 442 are provided with snap-fit ​​teeth, and the snap-fit ​​teeth on the first snap-fit ​​block 441 and the second snap-fit ​​block 442 face opposite directions.

[0049] When the I-beam 2 presses against the contact block 41, the contact block 41 presses against the support rod 431, causing the support rod 431 to slide on the T-shaped fixing member 3. Then, the support rod 431 drives the locking block 1 441. The locking teeth on the locking block 1 441 abut against the inclined surface of the locking teeth on the locking block 2 442. Then, the locking block 1 441 slides on the support rod 431 and presses against the support spring 443, allowing the support rod 431 to slide. When the I-beam 2 and the T-shaped fixing member 3 are completely in contact, the support rod 431 stops moving. Under the push of the support spring 443, the locking block 1 441 and the locking block 2 442 are locked together. By using the locking blocks 1 441 and the locking block 2 442 to limit the support rod 431, the support rod 431 can maintain stability when it drives the support block 42 to extend.

[0050] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5The auxiliary positioning mechanism 5 includes an inclined block 51 set on the T-shaped fixing member 3. The inclined surface of the inclined block 51 faces the support rod 431 and abuts against the support rod 431. A support assembly 54 is provided between the inclined block 51 and the T-shaped fixing member 3. A cone head 52 is fixed on the inclined block 51. A positioning groove 53 is opened on the I-beam 2. The end of the positioning groove 53 facing the cone head 52 is open.

[0051] As the I-beam 2 approaches the T-shaped fastener 3 and presses against the contact block 41, the support rod 431 pushes out the support block 42. At the same time, the support rod 431 abuts against the inclined surface of the tilting block 51, allowing the tilting block 51 to slide under the support of the support assembly 54. The tilting block 51 drives the cone head 52 to insert into the positioning groove 53 of the I-beam 2. When the I-beam 2 deviates, the inclined surface of the cone head 52 abuts against the edge of the positioning groove 53, allowing the I-beam 2 to be adjusted laterally. By allowing the inclined surface of the cone head 52 to abut against the edge of the positioning groove 53, the I-beam 2 is adjusted laterally, thereby further aligning the fixing holes on the T-shaped fastener 3 with the fixing holes on the I-beam 2, making it easier for the fixing bolts to pass through the I-beam 2 and the T-shaped fastener 3.

[0052] Reference Figure 3 and Figure 5 The support component 54 includes a support frame 541 fixed on a T-shaped fastener 3, an inclined block 51 passing through the support frame 541, and limit blocks 542 fixed on both sides of the inclined block 51. The limit blocks 542 are slidably connected to the support frame 541.

[0053] When the inclined block 51 is pushed by one end of the support rod 431, the inclined block 51 slides under the limit of the support frame 541. At the same time, the limit block 542 restricts the inclined block 51 to prevent it from falling out of the support frame 541. By allowing the inclined block 51 to slide in the support frame 541 and then using the limit block 542 to limit the inclined block 51, the inclined block 51 can stably drive the cone head 52 to move.

[0054] A construction process for prefabricated steel structure residential buildings, applicable to any of the aforementioned prefabricated steel structure residential buildings, wherein the construction process is as follows:

[0055] S1: When it is necessary to trim the steel structure house, first trim the foundation according to the drawings of the steel structure house and determine the position of several I-beam columns 1.

[0056] S2: Then, embed the corresponding fixing bolts at the fixed position of the I-beam column 1 in the foundation, then use the hoisting equipment to lift the I-beam column 1 to the position of the fixing bolts, then press the I-beam column 1 against the foundation, then use the fixing bolts to fix the I-beam column 1 to the foundation, and then use the fixing bolts to fix the T-shaped fastener 3 on the I-beam column 1.

[0057] S3: Then, using hoisting equipment, the I-beam 2 is lifted between the adjacent I-beam column 1, so that the I-beam 2 is flush with the T-shaped fastener 3 on the adjacent I-beam column 1. Then, the I-beam 2 is moved closer to the T-shaped fastener 3, so that the fixing surface on the T-shaped fastener 3 abuts against the I-beam 2. At the same time, the I-beam 2 presses against the contact block 41, the contact block 41 pushes the support rod 431, the support rod 431 drives the connecting rod 432, the connecting rod 432 drives the sliding block 433, and the sliding block 433 drives the support block 42 to extend out from the T-shaped fastener 3.

[0058] S4: Two support blocks 42 extending from the T-shaped fastener 3 simultaneously abut against the groove sidewall of the I-beam 2, so that the fixing holes on the I-beam 2 are aligned vertically with the fixing holes on the T-shaped fastener 3.

[0059] S5: While the I-beam 2 pushes the support rod 431, the support rod 431 pushes the tilting block 51, so that the tilting block 51 drives the cone head 52 under the restriction of the support frame 541. The cone head 52 is inserted into the positioning groove 53 on the I-beam 2. Under the restriction of the inclined surface of the cone head 52, the fixing hole on the I-beam 2 is horizontally aligned with the fixing hole on the T-shaped fastener 3. Then, the construction personnel use fixing bolts to pass through the T-shaped fastener 3 and the I-beam 2 to fix it, thus completing the connection between the I-beam column 1 and the I-beam 2.

[0060] Working principle: When constructing a steel structure house, firstly, according to the drawings of the steel structure house, the foundation is trimmed, and the positions of several I-beam columns 1 are determined. Then, corresponding fixing bolts are pre-embedded at the fixed positions of the I-beam columns 1 in the foundation. Then, the I-beam columns 1 are lifted to the position of the fixing bolts using hoisting equipment. Then, the I-beam columns 1 are pressed against the foundation. Then, the fixing bolts are used to fix the I-beam columns 1 to the foundation. Finally, T-shaped fasteners 3 are fixed to the I-beam columns 1 using fixing bolts.

[0061] During the installation of the I-beam 2, hoisting equipment is used to lift the I-beam 2 onto the side of the T-shaped fasteners 3 on the two I-beam columns 1. Then, the I-beam 2 is moved towards the T-shaped fasteners 3, allowing the T-shaped fasteners 3 to enter the groove of the I-beam 2. During this movement, the I-beam 2 presses against the contact block 41. Supported by the support rod 431, the contact block 41 moves closer to the T-shaped fastener 3. Then, the support rod 431 drives the connecting rod 432, which in turn drives the sliding block 433, causing the two sliding blocks 433 to move away from each other. Finally, the two sliding blocks 433 drive the support block 42, causing both support blocks 42 to simultaneously abut against the inner wall of the groove in the I-beam 2. The T-shaped fastener 3 is located in the middle of the I-beam 2. When the I-beam 2 approaches the T-shaped fastener 3 and presses against the contact block 41, the support rod 431 pushes out the support block 42. At the same time, the support rod 431 abuts against the inclined surface of the inclined block 51, allowing the inclined block 51 to slide under the support of the support assembly 54. The inclined block 51 drives the cone head 52 to insert into the positioning groove 53 of the I-beam 2. When the I-beam 2 deviates, the inclined surface of the cone head 52 abuts against the edge of the positioning groove 53, allowing the I-beam 2 to be adjusted laterally, so that the I-beam 2 is aligned with the fixing hole on the T-shaped fastener 3. Then, the fixing bolt is passed through to fix the I-beam 2 and the T-shaped fastener 3 together.
