Description

Technical Field

[0001] This utility model belongs to the technical field of building renovation tools, specifically relating to a support column reinforcement structure for building renovation. Background Technology

[0002] Support columns are columnar members in building, engineering, or mechanical structures used to bear vertical or lateral loads. Their main function is to provide structural stability and support. Existing support columns may experience the following problems after prolonged use:

[0003] 1. After prolonged use, concrete support columns are prone to cracking, leading to corrosion and rust of the internal reinforcing steel. As a result, the support columns fail to achieve their supporting efficiency and are prone to tilting or collapse. When reinforcing concrete support columns, temporary support columns are needed, followed by partial repair or recasting. This process is time-consuming, and even after repair, cracking may still occur in the concrete support columns, failing to achieve the desired repair efficiency.

[0004] 2. When wooden support columns corrode or become damaged after prolonged use, reinforcement can be achieved by either replacing the entire column or using an external wrapping method. However, when replacing the entire column, the new column may not align properly with the original support, resulting in insufficient support. External wrapping only provides temporary support; when the wooden column can no longer provide adequate support, the wrapped column may deform, and the repair quality may not meet the required reinforcement strength.

[0005] As mentioned above, the existing support columns have the following drawbacks when reinforcement: long construction period, failure to meet the predetermined support strength requirements, and unclear durability and stability after reinforcement. Utility Model Content

[0042] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model is described below with reference to specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. The structures, proportions, sizes, etc., illustrated in the accompanying drawings are only for illustrative purposes to aid those skilled in the art and are not intended to limit the implementation conditions of this utility model. Therefore, they have no substantial technical significance.

Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0043] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the solution according to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0044] Specific implementation method one: Combining Figure 1 The illustration shows this specific embodiment. This specific embodiment uses a modular base 1 for on-site assembly, and a top-fixed right-angle frame 4 for top fixation. A limiting mechanism 5 can limit and lift the top-fixed right-angle frame 4. The specific technical solution includes: a modular base 1, supporting columns 2, a reinforcing fixing plate 3, a top-fixed right-angle frame 4, and a limiting mechanism 5. Supporting columns 2 are bolted to the four corners of the upper end of the modular base 1. The modular base 1 allows for on-site assembly, facilitating rapid on-site construction. The supporting columns 2 are installed on the modular base 1 using a positioning method. Adjacent supporting columns... Several reinforcing plates 3 are bolted to the outer walls between columns 2. The reinforcing plates 3 can improve the stability and strength of the supporting columns 2, making the supporting columns 2 less prone to shaking. The combined base 1, the four supporting columns 2 and the several reinforcing plates 3 are connected to each other to form a reinforced support column. The four top fixed right angle brackets 4 are bolted to the outer upper side walls of two adjacent supporting columns 2. The lower ends of the four top fixed right angle brackets 4 are in contact with two limiting mechanisms 5. The limiting mechanisms 5 can limit and lift the top fixed right angle brackets 4. The limiting mechanisms 5 are welded to the outer walls of the supporting columns 2.

[0045] The working principle of this specific embodiment is as follows: In use, the combined base 1 is fixed around the bottom of the original support column. After the fixing is completed, the support columns 2 are installed at the four corners of the combined base 1. Then, the reinforcing fixing plate 3 is installed on the support column 2 to improve the strength and stability of the support column 2. After the installation is completed, the top fixing right angle bracket 4 is installed on the support column 2. At this time, the top fixing right angle bracket 4 is pushed up by the limiting mechanism 5 so that the top fixing right angle bracket 4 comes into contact with the top plate and fixes the top fixing right angle bracket 4 to the top plate. After the fixing is completed, the limiting mechanism 5 realizes the limiting of the top fixing right angle bracket 4, which can improve the stability of the top fixing right angle bracket 4. When the original support column is severely damaged, it is repaired by repair. After the repair is completed, the original support column is reinforced.

[0046] Specific Implementation Method Two: Combining Figure 2 , Figure 3 , Figure 4 , Figure 5 The illustration shows this specific embodiment, which is a further limitation of Specific Embodiment 1.

The T-shaped plug-in block 1-21 is inserted into the T-shaped plug-in groove 1-11 to enable the assembly of the plug-in mating post 1-1 and the plug-in post 1-2. Both sides of the plug-in mating post 1-1 are provided with connecting through holes 1-12, which are connected to the T-shaped plug-in groove 1-11. The connecting through holes 1-12 allow the locking bolt 1-5 to pass through. The outer side of the connecting through holes 1-12 is connected to the countersunk grooves 1-13 opened on the two outer side walls of the plug-in mating post 1-1. The countersunk grooves 1-13 allow the tail of the locking bolt 1-5 to be inserted without affecting the appearance. The T-shaped plug-in blocks 1-21 of the two plug-in posts 1-2 are respectively inserted into the T-shaped plug-in grooves 1-11 of the plug-in mating post 1-1. The locking bolt 1-5 passes through the connecting through holes 1-12 and is connected to the connecting threaded hole 1-22 on the T-shaped plug-in block 1-21.

[0047] As described above, in order to achieve the connection between the plug-in mating column 1-1, the plug-in column body 1-2, and the supporting column 2 using bolts and positioning, the following technical solution is adopted: Both sides of the plug-in mating column 1-1 and the plug-in column body 1-2 are provided with column fixing threaded holes 1-4 for fixing to the supporting column 2. The column fixing threaded holes 1-4 can achieve the fixing and locking of the supporting column 2.

Both the plug-in mating column 1-1 and the plug-in column body 1-2 are provided with a vertically penetrating fixing through hole 1-6. The outer end of the fixing through hole 1-6 is connected to a countersunk hole 1-7. The fixing through hole 1-6 can fix the plug-in mating column 1-1 and the plug-in column body 1-2 to the ground or a supporting plane.

[0048] In this specific embodiment, during installation, the plug-in mating column 1-1 and the plug-in column body 1-2 are placed outside the original support column. Then, the T-shaped plug-in block 1-21 is inserted into the T-shaped plug-in slot 1-11 to assemble the plug-in mating column 1-1 and the plug-in column body 1-2. After assembly, the locking bolt 1-5 is inserted into the connecting through hole 1-12 and connected to the connecting threaded hole 1-22 on the T-shaped plug-in block 1-21. At this time, the assembly is completed. Then, the combined base 1 is fixed on the ground or a plane. When fixing, the expansion bolt is inserted into the fixing through hole 1-6 for fixing.

The support column 2 can achieve positioning and fixed installation, which can improve the stability of the support column 2.

[0051] Specific implementation method four: Combination Figure 8 , Figure 9 The illustration shows this specific embodiment, which is a further limitation of embodiment one, two, or three. This specific embodiment improves strength by reinforcing the fixing plate 3, and the specific technical solution adopted is as follows: each of the four corners of the reinforcing fixing plate 3 is provided with a fixing through hole 3-1, which allows bolts to be inserted to facilitate the fixing of the reinforcing fixing plate 3.

[0052] In this specific embodiment, the reinforcing fixing plate 3 uses transverse reinforcing strips 3-3, long longitudinal reinforcing strips 3-4, and short longitudinal reinforcing strips 3-5 to improve its strength, making the reinforcing fixing plate 3 less prone to deformation. At the same time, the reinforcing fixing plate 3 is installed in the fixing plate connecting groove 2-2 of the supporting column 2, which enables the installation of the reinforcing fixing plate 3.

[0053] Specific Implementation Method Five: Combining Figure 10 The illustration shows this specific embodiment, which is a further limitation of embodiment one, two, three or four. In this specific embodiment, the top fixed right angle bracket 4 is used to fix it to the top plate.

[0056] In this specific embodiment, during adjustment, the top fixed right angle bracket 4 is lifted and limited by restricting the head of the bolt 5-2, so that the flat surface of the top fixed right angle bracket 4 can be in close contact with the top plate, which facilitates the fixing of the top fixed right angle bracket 4. At this time, the top fixed right angle bracket 4 is fixed to the support column 2 by bolts.
