Description

Technical Field

[0001] This invention relates to the field of prefabricated building technology, specifically to a steel column installation structure and its installation method for prefabricated residential buildings. Background Technology

[0002] Prefabricated buildings refer to buildings where a large amount of on-site work in traditional construction methods is transferred to factories. Building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in factories, transported to the construction site, and assembled and installed on-site using reliable connection methods.

[0003] Prefabricated buildings mainly include precast concrete structures, steel structures, and modern wood structures. Because they adopt standardized design, factory production, assembly construction, information management, and intelligent applications, they represent modern industrialized production methods.

[0004] Due to the practicality of prefabricated buildings, an increasing number of industrial buildings often require connecting structures to support them. Commonly used connecting structures are steel structures, which typically include columns and beams. Similarly, prefabricated construction of residential buildings not only improves construction efficiency but also saves materials. However, existing steel beam-column connecting structures are complex to connect, inconvenient to disassemble and replace, and cannot be moved or adjusted as needed after connection. Therefore, this paper proposes a steel column installation structure and its installation method for prefabricated residential buildings to solve these problems. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a steel column installation structure and its installation method for prefabricated housing, which has the advantages of convenient disassembly and replacement. It solves the problems that the existing steel structure beam and column connection structures are relatively complex to connect, inconvenient to disassemble and replace, and cannot be moved and adjusted as needed after connection.

[0006] To achieve the aforementioned purpose of convenient disassembly and replacement, the present invention provides the following technical solution: a steel column installation structure for prefabricated housing, comprising a steel column body, an installation sleeve fitted on the outside of the steel column body, an installation component at the bottom of the steel column body, the installation component consisting of a fixing plate and a connecting plate, the steel column body being fixedly welded to the top of the connecting plate, a connecting component being provided inside the installation sleeve, and a reinforcing component being provided at the bottom of the steel column body;

[0007] The connecting component includes a locking block that is fixedly welded to the outside of the mounting sleeve. The locking block has a locking groove inside and a first mounting hole that communicates outward inside. A positioning bolt is inserted into the first mounting hole.

[0008] The reinforcement assembly includes a fixing sleeve fitted around the outside of the steel column body, a connecting plate set on the top of the fixing plate, and a support rod set between the fixing sleeve and the connecting block. The upper and lower ends of the support rod are respectively rotatably connected to a first hinge seat and a second hinge seat. The first hinge seat is fixedly installed on the side wall of the fixing sleeve, and the second hinge seat is fixedly welded to the top of the connecting block.

[0009] Furthermore, the mounting sleeve has an outwardly communicating opening inside, and the opening is adapted to the main body of the steel column, through which the main body of the steel column penetrates the interior of the mounting sleeve.

[0010] Furthermore, an opening is provided on one side of the mounting sleeve, and a mounting block is fixedly welded to the outside of the opening. There are two mounting blocks, and each of the two mounting blocks has a second mounting hole inside, and a locking bolt is provided inside the second mounting hole.

[0011] Furthermore, a fastening bolt is installed inside the mounting sleeve, and the fastening bolt extends into the interior of the steel column body. Both the steel column body and the mounting sleeve have threaded holes that are compatible with the fastening bolt.

[0012] Furthermore, there are two connecting components, and the two connecting components are located on the front and left side of the mounting sleeve, respectively.

[0013] Furthermore, the connecting plate is equipped with connecting bolts extending into the fixed plate. Both the connecting plate and the fixed plate have connecting holes adapted to the connecting bolts, and the number of connecting bolts is not less than four.

[0014] Furthermore, a plug extending into the interior of the fixing plate is fixedly installed at the bottom of the connecting block, and a slot adapted to the plug is opened inside the fixing plate, and the plug is plugged into the slot.

[0015] Furthermore, the connecting block is equipped with fixing bolts extending into the fixing plate. Both the fixing plate and the connecting block have fixing holes adapted to the fixing bolts, and the number of fixing bolts is not less than four.

[0016] Furthermore, the fixing sleeve is equipped with positioning bolts extending into the steel column body, and the number of positioning bolts is not less than four. The number of connecting blocks and support rods in the reinforcement assembly is three each, and the three connecting blocks and three support rods are evenly distributed around the fixing sleeve.

[0017] Another technical problem to be solved by the present invention is to provide a method for installing steel columns for prefabricated housing, comprising the following steps:

[0018] The downward displacement fixing sleeve and the support rod are rotated to make the connecting block fit against the upper surface of the connecting plate. At this time, the insert block is inserted into the inside of the slot, thereby keeping the fixing sleeve fixed. This not only improves the stability of the steel column body, but also improves the support effect of the reinforcement components. Finally, the fixing bolts and positioning bolts are used to fix the connecting block and the fixing sleeve respectively, completing the installation of the steel column body.

[0019] Next, align the mounting sleeve with the opening and then move the mounting sleeve downwards. At this time, the main body of the steel column passes through the opening and penetrates the interior of the mounting sleeve. After the mounting sleeve has moved to the appropriate height, fix it with locking bolts and fastening bolts.

[0020] 3) During installation, the crossbeam is initially fixed by placing it into the slot. Then, the positioning bolt is inserted into the first mounting hole and passes through the inside of the crossbeam to further fix the crossbeam and prevent it from shaking during installation.

[0021] Compared with the prior art, the present invention provides a steel column installation structure and installation method for prefabricated housing, which has the following beneficial effects:

[0022] 1. The steel column installation structure and its installation method for prefabricated housing involves a downward displacement of the installation sleeve, allowing the steel column body to pass through the sleeve's opening. After the sleeve reaches a suitable height, it is initially fixed using locking bolts and a second installation hole. The sleeve is then further secured with tightening bolts, improving its fixation and enhancing the connection between the beam and the locking block. After the sleeve is fixed, the beam is placed into the slot for initial fixation. A positioning bolt is then inserted into the first installation hole and passes through the beam to further secure it, preventing wobbling during installation. The use of connecting components facilitates not only beam fixation but also movement and adjustment, allowing for easy connection between the beam and the steel column body. This enables convenient disassembly and replacement, solving the problems of complex connection structures for existing steel beams and columns, which are difficult to disassemble and replace, and cannot be moved or adjusted as needed after connection.

[0023] 2. The steel column installation structure and its installation method for prefabricated housing involves displacing the fixing sleeve downwards and rotating the support rod to make the connecting block fit against the upper surface of the connecting plate. At this time, the insert block is inserted into the slot, thereby keeping the fixing sleeve fixed. This not only improves the stability of the steel column body but also enhances the support effect of the reinforcement components. Finally, fixing bolts and positioning bolts are used to fix the connecting block and the fixing sleeve respectively, completing the installation of the steel column body. Through the combined use of the installation components and reinforcement components, the stability of the steel column body installation is ensured, achieving the advantage of stable installation.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on 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.

[0030] Please see Figure 1-4 A steel column installation structure for prefabricated housing includes a steel column body 1, an installation sleeve 2 fitted around the outside of the steel column body 1, and an installation component 3 at the bottom of the steel column body 1. The installation component 3 consists of a fixing plate 31 and a connecting plate 32. The steel column body 1 is fixedly welded to the top of the connecting plate 32. Connecting bolts 33 extending into the fixing plate 31 are installed inside the connecting plate 32. Both the connecting plate 32 and the fixing plate 31 have connecting holes adapted to the connecting bolts 33, and the number of connecting bolts 33 is not less than four. By installing the connecting bolts 33, the steel column body 1 can be initially fixed, facilitating the subsequent connection of crossbeams.

[0031] Furthermore, the connecting bolts 33 are distributed in a ring around the connecting plate 32.

[0032] In this embodiment, a connecting component is provided on the outside of the mounting sleeve 2. The connecting component includes a locking block 23 fixedly welded to the outside of the mounting sleeve 2. The locking block 23 has a locking groove 230 inside and a first mounting hole 231 that communicates outward inside. A positioning bolt 232 is inserted into the first mounting hole 231. The mounting sleeve 2 has an outward through-hole 21 inside, which is adapted to the steel column body 1. The steel column body 1 passes through the interior of the mounting sleeve 2 through the through-hole 21. An opening is provided on one side of the mounting sleeve 2, and two mounting blocks 22 are fixedly welded to the outside of the opening. Each of the two mounting blocks 22 has a second mounting hole 24 inside, and a locking bolt 25 is provided inside the second mounting hole 24.

[0033] The mounting sleeve 2 is equipped with a fastening bolt 26, which extends into the interior of the steel column body 1. Both the steel column body 1 and the mounting sleeve 2 have threaded holes that are compatible with the fastening bolt 26.

[0034] Understandably, by displacing the mounting sleeve 2 downwards, the steel column body 1 passes through the through-hole 21 into the interior of the mounting sleeve 2. After the mounting sleeve 2 is displaced to a suitable height, the mounting sleeve 2 is initially fixed by using the locking bolt 25 and the second mounting hole 24. Then, the mounting sleeve 2 is further fixed by the fastening bolt 26 to improve the fixing effect of the mounting sleeve 2 and at the same time improve the engagement between the crossbeam and the locking block 23. After the mounting sleeve is fixed, the crossbeam is placed into the slot 230 to initially fix the crossbeam. Then, the positioning bolt 232 is inserted into the first mounting hole 231 and passes through the interior of the crossbeam to further fix the crossbeam.

[0035] It should be noted that there are two connecting components, and the two connecting components are located on the front and left side of the mounting sleeve 2, respectively.

[0036] In this embodiment, a reinforcing component 4 is provided at the bottom of the steel column body 1. The reinforcing component 4 includes a fixing sleeve 41 sleeved on the outside of the steel column body 1, a connecting plate 32 set on the top of the fixing plate 31, and a support rod 43 set between the fixing sleeve 41 and the connecting block 42. The upper and lower ends of the support rod 43 are respectively rotatably connected to a first hinge seat 44 and a second hinge seat 45. The first hinge seat 44 is fixedly installed on the side wall of the fixing sleeve 41, and the second hinge seat 45 is fixedly welded to the top of the connecting block 42.

[0037] The connecting block 42 has an insert 421 fixedly installed at its bottom, extending into the fixed plate 31. The fixed plate 31 has a slot 422 that matches the insert 421, and the insert 421 is inserted into the slot 422. The connecting block 42 has a fixing bolt 423 installed inside, extending into the fixed plate 31. Both the fixed plate 31 and the connecting block 42 have fixing holes that match the fixing bolts 423, and the number of fixing bolts 423 is not less than four.

[0038] Furthermore, the fixing sleeve 41 is equipped with positioning bolts 46 extending into the steel column body 1. There are no fewer than four positioning bolts 46. The reinforcing component 4 has three connecting blocks 42 and three support rods 43, and the three connecting blocks 42 and three support rods 43 are evenly distributed around the fixing sleeve 41.

[0039] Understandably, by displacing the fixing sleeve 41 downward and rotating the support rod 43, the connecting block 42 is brought into contact with the upper surface of the connecting plate 32. At this time, the insert block 421 is inserted into the slot 422, thereby keeping the fixing sleeve 41 fixed. This not only improves the stability of the steel column body 1, but also improves the support effect of the reinforcement component 4. Finally, the fixing bolt 423 and the positioning bolt 46 fix the connecting block 42 and the fixing sleeve 41 respectively, completing the installation of the steel column body 1. Through the combined use of the installation parts and the reinforcement component 4, the installation of the steel column body is ensured to be stable, achieving the advantage of stable installation.

[0040] Another technical problem to be solved by the present invention is to provide a method for installing steel columns for prefabricated housing, comprising the following steps:

[0041] 1) Displace the fixed sleeve 41 downward and rotate the support rod 43 so that the connecting block 42 fits against the upper surface of the connecting plate 32. At this time, the insert block 421 is inserted into the inside of the slot 422, thereby keeping the fixed sleeve 41 fixed. This not only improves the stability of the steel column body 1, but also improves the support effect of the reinforcement component 4. Finally, the fixing bolt 423 and the positioning bolt 46 fix the connecting block 42 and the fixed sleeve 41 respectively, completing the installation of the steel column body 1.

[0042] 2) Next, align the mounting sleeve 2 with the opening 21, and then move the mounting sleeve 2 downward. At this time, the steel column body 1 passes through the inside of the mounting sleeve 2 through the opening 21. After the mounting sleeve 2 is moved to a suitable height, it is fixed by locking bolt 25 and fastening bolt 26.

[0043] 3) During installation, the crossbeam is initially fixed by placing it into the slot 230. Then, the positioning bolt 232 is inserted into the first mounting hole 231 and passes through the inside of the crossbeam to further fix the crossbeam and prevent it from shaking during installation.

[0044] The beneficial effects of the above embodiments are as follows:

[0045] The steel column installation structure and its installation method for prefabricated housing involves downward displacement of the installation sleeve 2, allowing the steel column body 1 to pass through the through-hole 21 into the interior of the installation sleeve 2. After the installation sleeve 2 has been displaced to a suitable height, it is initially fixed by using the locking bolt 25 and the second installation hole 24. Then, the installation sleeve 2 is further fixed by the fastening bolt 26, improving the fixing effect of the installation sleeve 2 and simultaneously improving the engagement between the crossbeam and the locking block 23. After the installation sleeve 2 is fixed, the crossbeam is placed into the slot 230 to initially fix the crossbeam. Then, the positioning bolt 232 is inserted into the first installation hole 231 and passes through the interior of the crossbeam, thereby further fixing the crossbeam and preventing it from shaking during installation. The use of connecting components not only facilitates the fixing of the crossbeam but also facilitates its movement and adjustment, making it easy to connect the crossbeam to the steel column body 1. This achieves advantages such as convenient disassembly and replacement, solving the problems of existing steel structure beam and column connection structures being complex to connect, inconvenient to disassembly and replacement, and unable to move and adjust the connected beams and columns as needed.
