Description

Technical Field

[0001] This utility model relates to the field of building wall panel external mounting technology, and in particular to an external mounting structure for prefabricated building columns. Background Technology

[0002] With the acceleration of the industrialization of construction, prefabricated buildings have been widely used in the modern construction field due to their advantages such as high efficiency, environmental protection, and controllable quality. Among them, the external mounting structure of prefabricated building columns is a key technology that plays a decisive role in the overall stability and construction efficiency of the building. This structure enables rapid assembly by externally mounting prefabricated columns to the main structure of the building, reducing on-site wet work and effectively improving the industrialization level of building construction. It has shown great application potential in various scenarios such as residential buildings, commercial buildings, and industrial plants, and is an important technological direction for promoting the transformation and upgrading of the construction industry.

[0003] In existing prefabricated building column external installation technology, traditional mechanical connection methods are usually adopted. The common practice is to reserve connection points on the main building structure, install connection plates at the ends of prefabricated columns, and then use lifting equipment to lift the columns to the installation position. After that, the columns are manually supported to align the bolt holes on the connection plates with the holes of the reserved connection points, and then bolts are used to tighten the connection. This installation method mainly relies on manual operation to ensure the accurate and stable position of the columns. Its technical principle is based on simple mechanical cooperation and tightening, using the tension of the bolts to form a stable connection between the columns and the main building structure, thus realizing the external installation of the columns.

[0004] However, the existing installation method has obvious drawbacks. During the bolt tightening process, due to the lack of effective temporary fixing measures, construction workers need to continuously hold the column by hand to maintain its stability and accurate position. This not only increases the labor intensity of construction workers but also poses significant safety hazards. At the same time, manual support cannot guarantee the absolute accuracy of the column position, which can easily lead to installation errors, affecting the stability of the overall building structure and the construction quality. In addition, this operation method also greatly limits construction efficiency, prolongs the construction cycle, and fails to fully leverage the advantages of efficient construction of prefabricated buildings. It has become a bottleneck restricting the further development of prefabricated building column external installation technology. Therefore, an external installation structure for prefabricated building columns is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an external mounting structure for prefabricated building columns, which aims to improve the problem that bolt fixing in the prior art requires manual support of the columns and is inconvenient to operate.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An externally mounted structure for prefabricated building columns includes a wall, on the outer wall of which columns are provided, and on the outer wall of the columns are connecting components.

[0008] The connecting assembly includes a connecting plate, the outer wall of which is fixedly connected to the outer wall of the column. A reserved groove is provided inside the wall, and bolt holes are provided inside the connecting plate. A reserved column is fixedly connected to one side of the bolt holes. The outer wall of the reserved column is slidably connected inside the reserved groove, and an adjustment assembly is provided inside the reserved column.

[0009] As a further description of the above technical solution:

[0010] The adjustment assembly includes a telescopic plate and a limiting groove formed inside the reserved column, with the outer wall of the telescopic plate slidably connected inside the limiting groove.

[0011] As a further description of the above technical solution:

[0012] A soft pad is fixedly connected to the outer wall of the telescopic plate, and the soft pad is in contact with the inner wall of the reserved groove.

[0013] As a further description of the above technical solution:

[0014] The telescopic plate has a transmission groove inside and a sliding groove inside.

[0015] As a further description of the above technical solution:

[0016] A tie rod is slidably connected inside the reserved column, and the outer wall of the tie rod is slidably connected inside the connecting plate.

[0017] As a further description of the above technical solution:

[0018] A limiting disc is fixedly connected to the outer wall of the pull rod, and a transmission column is fixedly connected to one end of the pull rod.

[0019] As a further description of the above technical solution:

[0020] The outer wall of the transmission column is slidably connected to the inside of the slide groove, and slide columns are fixedly connected to both ends of the transmission column. The outer wall of the slide column is slidably connected to the inside of the transmission groove.

[0021] As a further description of the above technical solution:

[0022] A spring is fitted on the outer wall of the pull rod. One end of the spring is fixedly connected to the outer wall of the limiting disc, and the other end of the spring is fixedly connected to the inner wall of the reserved column.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, a pre-drilled hole is precisely opened in the wall, and then the pre-set pre-drilled column of the connecting plate is inserted into the pre-drilled hole. The column can be quickly and stably fixed to the wall, and then bolts can be used for tightening. Since the cooperation between the pre-drilled column and the pre-drilled hole has achieved the initial fixation of the column, no manual support is required in the bolt fixing process. This solves the problem that the bolt fixing requires manual support of the column and is inconvenient to operate in traditional installation, and significantly improves the installation efficiency, construction safety and installation accuracy.

[0025] 2. In this utility model, when the reserved column is inserted into the reserved hole in the wall, the spring rebound will drive the soft pad to automatically expand and contract according to the size of the reserved hole, tightly supporting the hole wall. Regardless of the difference in the specifications of the reserved hole, it can achieve adaptive adjustment, which solves the problem of installation difficulties caused by the mismatch between the reserved hole and the reserved column size, and significantly improves the versatility, stability and construction efficiency of column installation.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1-3 An embodiment of this utility model is provided: an externally mounted column structure for prefabricated buildings, including a wall 1. The wall 1 serves as the main load-bearing and enclosure structure of the building and is usually made of reinforced concrete, which has good strength and stability and can withstand various loads of the building. A column 2 is provided on the outer wall of the wall 1, and a connecting component is provided on the outer wall of the column 2.

[0035] The connecting assembly includes a connecting plate 3, which is made of steel plate with a certain thickness and strength. Its outer wall is fixedly connected to the outer wall of the column 2 by welding to ensure the firmness of the connection. The outer wall of the connecting plate 3 is fixedly connected to the outer wall of the column 2. A reserved groove 6 is opened inside the wall 1. The reserved groove 6 is reserved during the construction of the wall 1 for subsequent cooperation with the reserved column 5 to provide positioning and support for the installation of the column 2. The connecting plate 3 has bolt holes 4 inside for bolts to pass through. The connecting plate 3 is further fixed to the wall 1 by bolts to enhance the stability of the connection. A reserved column 5 is fixedly connected to one side of the bolt hole 4. The reserved column 5 is also made of steel structure. Its outer wall can be tightly slidably connected to the inside of the reserved groove 6. When the reserved column 5 is inserted into the reserved groove 6, the initial positioning and fixation of the column 2 is achieved. The outer wall of the reserved column 5 is slidably connected to the inside of the reserved groove 6. An adjustment component is set inside the reserved column 5.

[0036] Specifically, in prefabricated building construction, the installation and connection of wall 1 and column 2 is a key step in ensuring the stability of the building structure. During installation, firstly, a pre-reserved groove 6 needs to be precisely drilled inside wall 1 according to the design position of the pre-reserved column 5. After the pre-reserved groove 6 is opened, the column 2 is moved using lifting equipment, which drives the connecting plate 3 at its end to move synchronously, so that the pre-reserved column 5 on the connecting plate 3 is precisely aligned with the pre-reserved groove 6 in wall 1. Then, the pre-reserved column 5 is smoothly inserted into the pre-reserved groove 6 to achieve the initial fixation of the column 2. This operation effectively limits the shaking and displacement of the column 2. Finally, high-strength bolts are precisely driven into the bolt holes 4 on the connecting plate 3 to complete the fastening of the connecting plate 3, thereby firmly installing the column 2 on wall 1. This installation process does not require manual support of the column 2 when fixing the bolts, effectively avoiding the safety risks of falling from height and component compression caused by manual support in traditional installation, and greatly improving construction safety and installation efficiency.

[0037] Reference Figures 1-5The adjustment assembly includes a telescopic plate 7 and a limiting groove 14 formed inside the reserved column 5. The outer wall of the telescopic plate 7 is slidably connected to the inside of the limiting groove 14. A soft pad 8, made of rubber, is fixedly connected to the outer wall of the telescopic plate 7, providing good elasticity and flexibility. The soft pad 8 is used to fit against the inner wall of the reserved groove 6. After the reserved column 5 is inserted into the reserved groove 6, the soft pad 8 can fill the gap between the two, preventing loosening due to size differences. It also plays a role in buffering and shock absorption, reducing the impact of vibration on the connection between the column 2 and the wall 1 during the use of the building, thereby extending the service life of the connection structure. The soft pad 8 fits against the inner wall of the reserved groove 6. A transmission groove 13 and a sliding groove 15 are formed inside the telescopic plate 7. A tie rod 16, made of stainless steel, is slidably connected inside the reserved column 5. With high strength and corrosion resistance, its outer wall can be flexibly slidably connected to the inside of the connecting plate 3. The outer wall of the pull rod 16 is slidably connected to the inside of the connecting plate 3. A limiting disc 10 is fixedly connected to the outer wall of the pull rod 16. The limiting disc 10 is made of carbon steel and can limit the sliding range of the pull rod 16. A transmission column 11 is fixedly connected to one end of the pull rod 16. The outer wall of the transmission column 11 is slidably connected to the inside of the slide groove 15. Sliding columns 12 are fixedly connected to both ends of the transmission column 11. The outer wall of the sliding column 12 is slidably connected to the inside of the transmission groove 13. The pull rod 16, transmission column 11 and sliding column 12 cooperate with each other. When the pull rod 16 is pulled, the transmission column 11 will slide in the sliding groove 15, which will drive the sliding column 12 to slide in the transmission groove 13, and finally realize the telescopic movement of the telescopic plate 7 in the limiting groove 14. A spring 9 is sleeved on the outer wall of the pull rod 16. One end of the spring 9 is fixedly connected to the outer wall of the limiting disc 10, and the other end of the spring 9 is fixedly connected to the inner wall of the reserved column 5.

[0038] Specifically, in the process of externally mounted installation of prefabricated building columns, the fitting connection between the reserved column 5 and the reserved groove 6 in the wall 1 is crucial to ensuring installation accuracy and stability. When placing the reserved column 5, the construction personnel need to pull the pull rod 16 first. This pull rod 16 is tightly connected to the transmission column 11. As the pull rod 16 is pulled, the transmission column 11 moves smoothly along the preset track in the slide groove 15. At the same time, the transmission column 11 drives the limiting disc 10 to slide synchronously, compressing the spring 9. While the spring 9 is deformed by the force, it transmits the force to the sliding column 12, causing the sliding column 12 to move in the transmission groove 15. The movable plate 7 slides flexibly within the movable groove 13, thereby causing the telescopic plate 7 to retract within the limiting groove 14. At this time, the reserved column 5 can be smoothly inserted into the reserved groove 6. After the reserved column 5 is in place, the pull rod 16 is released, and the compressed spring 9 quickly rebounds, causing the sliding column 12 to return to its original position and pushing the telescopic plate 7 to extend outward, so that the soft pad 8 at the end of the telescopic plate 7 fits tightly against the inner wall of the reserved groove 6. This process realizes the adaptive adjustment of the internal space of the reserved groove 6, ensuring that the connection between the reserved column 5 and the wall 1 is tighter and more stable, effectively improving the versatility and reliability of the installation structure.

[0039] Working principle: When installing on wall 1, firstly, a reserved groove 6 is drilled inside wall 1 according to the position of the reserved column 5. Then, the connecting plate 3 is moved by moving the column 2 to align the reserved column 5 with the reserved groove 6 and insert it to initially fix the column 2. Then, the bolts are driven into the bolt hole 4 to fix the connecting plate 3, thus avoiding the need for manual support during fixing, which may cause danger.

[0040] In addition, when placing the reserved column 5, the pull rod 16 needs to be pulled. The pull rod 16 drives the transmission column 11 to move inside the slide groove 15, and drives the limiting disc 10 to slide and compress the spring 9, so that the slide column 12 can slide inside the transmission groove 13, and the telescopic plate 7 can slide inside the limiting groove 14 and retract. Then, after the reserved column 5 is inserted, the pull rod 16 is released. The spring 9 rebounds and drives the slide column 12 back to its original position, and the telescopic plate 7 is pushed out, so that the soft pad 8 fits against the inner wall of the reserved groove 6, thereby adapting to the internal space of the reserved groove 6 and fitting better.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
