Abstract
Description
Technical Field
[0001] This utility model relates to a reinforcement structure, and more specifically, a metal support reinforcement structure. Background Technology
[0002] As a crucial infrastructure in industrial production and warehousing, steel chambers rely on their bottom steel channels for bearing the overall structural weight and distributing loads. With increasing service life, these channels are prone to structural damage due to corrosion, fatigue, and load variations, necessitating renovation and replacement to ensure the safe operation of the steel chamber. The core aspect of steel chamber channel renovation is the splicing and reinforcement of the new and old steel channels.
[0003] Currently, the traditional steel channel splicing reinforcement process has the following aspects that deserve attention: First, the flatness of the top surfaces of the old and new steel channels; second, if structural adhesive is used for reinforcement, traditional processes struggle to achieve precise positioning and pressure maintenance during the adhesive curing process, making the adhesive layer prone to hollowing and detachment due to slight displacement of the steel channel, resulting in a significant decrease in reinforcement effectiveness; third, the connection points between the reinforcement components and the steel channel tend to protrude from the channel surface, affecting not only the appearance flatness but also potentially becoming weak points in stress, reducing the overall structural load-bearing capacity; fourth, traditional reinforcement components are mostly custom-made parts, resulting in high material costs, and leftover parts after construction are difficult to reuse, leading to resource waste and increased construction costs. Utility Model Content
[0004] This utility model provides a metal support and reinforcement structure, the purpose of which is to assist in the renovation of steel channels.
[0005] The above objectives are achieved through the following technical solutions:
[0006] A metal support reinforcement structure includes a base plate and a column fixed to the upper end of the base plate. The column and at least one set of face-to-face edges on the base plate are spaced apart, and a detachable sleeve is fitted on the column.
[0007] The upper surface of the base plate is provided with a channel.
[0008] The width of the opening at the top of the channel is smaller than the maximum width inside the channel, and the solidified material filling the channel can hook onto the base plate.
[0009] The channel has a circular arc structure.
[0010] The cylinder is cylindrical, and external threads are provided on the outer cylindrical surface.
[0011] The column is the tail of the bolt.
[0012] The column is welded to the base plate.
[0013] A groove is provided on the upper end face of the base plate, and the weld between the base plate and the column is located in the groove and is lower than the upper end face of the base plate.
[0014] The sleeve is an elastic body that can expand to fit over a column and then contract to hold it securely against the column. Alternatively, the inner wall of the sleeve is a cylindrical surface with internal threads.
[0015] The aforementioned metal support reinforcement structure is used in the renovation of the channel steel of the steel chamber.
[0016] The beneficial effects of the metal support and reinforcement structure of this utility model are as follows:
[0017] By fitting the column with the through holes on the new and old steel channels, the base plate can be positioned at the joint between the new and old steel channels, ensuring alignment. Removable rubber sleeves or threaded sleeves provide stable pressure during the curing process of the structural adhesive and temporarily fix the base plate, ensuring a tight fit between the base plate and the lower end face of the steel channel. This prevents adhesive layer delamination and detachment, significantly improving the bonding reinforcement effect. The threaded sleeve achieves pre-tightening through threaded engagement, offering greater pressure control; the rubber sleeve offers advantages such as convenient installation and strong adaptability, and can be flexibly adjusted according to the column diameter.
[0018] The groove design on the upper surface of the base plate increases the contact area between the structural adhesive and the base plate, improving the bonding strength. On the other hand, the shrinking top opening allows the cured structural adhesive to form a "hook" structure, further enhancing the connection reliability between the base plate and the steel channel and preventing relative slippage.
[0019] The trough design conceals the weld bead between the column and the base plate within the trough, ensuring that the weld bead does not protrude from the upper surface of the base plate. This not only guarantees a tight fit between the lower end of the steel trough and the base plate, but also prevents the weld bead from becoming a weak point of stress, thereby improving the overall structural flatness and load-bearing stability.
[0020] The column can be constructed using the shaft portion of a long bolt with the head removed, or the tail portion of the bolt with the head cut off, allowing for the use of locally sourced materials and eliminating the need for custom-made parts. This significantly reduces material costs, and the internal thread dimensions of the sleeve can be synchronized with the standard bolt dimensions. The column portion exposed above the base plate can be reused after being cut off, improving resource utilization. Furthermore, the overall construction process is simple, requiring no complex or specialized equipment, which shortens the construction period and reduces labor costs.
[0021] The concealed welding package in the sink is designed so that the upper end face of the column after removal coincides with the upper end face of the steel trough. Furthermore, the sleeve is detachable and leaves no protruding parts, ensuring that both the upper and lower end faces of the steel trough remain flat. This avoids interference from protruding structures in subsequent use and eliminates stress concentration problems caused by protruding parts, thereby improving the overall structural integrity and service life of the bottom of the steel chamber.

[0027] A metal support and reinforcement structure, reference Figures 1 to 4 It includes a base plate 1 and a column 2 fixed to the upper end of the base plate 1, with a detachable sleeve 3 fitted on the column 2.
[0028] Operating principle: For example, in the renovation of steel channel steel in a steel chamber, the old steel channel is removed, and a new steel channel is spliced together with the old one, ensuring that the upper ends of the new and old channels are aligned. For ease of description, please refer to... Figure 4 The first metal plate 4 forms the upper structure of the new steel channel, and the second metal plate 5 forms the upper structure of the old steel channel. The upper surfaces of the first metal plate 4 and the second metal plate 5 are aligned. Then, through holes are simultaneously drilled in both the first metal plate 4 and the second metal plate 5, with the central axis of the through holes located at the joint between the first metal plate 4 and the second metal plate 5. The new steel channel is then removed, and structural adhesive is applied to the upper surface of the base plate 1. The column 2 is placed halfway through the through hole in the second metal plate 5. The new steel channel is then rejoined with the old steel channel, at which point the first metal plate 4 and the second metal plate 5 are realigned, and the column 2 is completely inserted into the through hole. The column 2 is then lifted, causing the structural adhesive on the upper surface of the base plate 1 to adhere to the lower surfaces of the first metal plate 4 and the second metal plate 5. The sleeve 3 is then inserted into the column 2 until the lower surface of the sleeve 3 contacts the upper surfaces of the first metal plate 4 and the second metal plate 5, maintaining the base plate 1 and its adhesive surface in contact with the lower surfaces of the first metal plate 4 and the second metal plate 5. After the structural adhesive has cured, remove the sleeve 3 and cut / shear the column 2 exposed above the base plate 1, so that the upper end face of the column 2 coincides as much as possible with the upper end face of the first metal plate 4 and the second metal plate 5. Finally, weld the upper end of the column 2 onto the first metal plate 4 and the second metal plate 5.
[0029] The sleeve 3 can be a rubber sleeve, which expands and fits onto the column 2, then naturally contracts and returns to its original position, tightly clamping onto the column 2. The column 2 is a cylinder with threads on its outer cylindrical surface, and its material can be one of copper, stainless steel, carbon steel, or alloy steel. Alternatively, the shank remaining after removing the head of a long bolt can be used to weld the column 2 to the upper end of the base plate 1. In this way, the column 2 exposed above the base plate 1 can be reused after removal. Alternatively, the bolt can be machined, with the bolt head cut off, leaving the tail as the column 2, utilizing readily available materials. The sleeve 3 can also be upgraded to a more durable plastic / metal sleeve with internal threads, screwed onto the column 2, with the two connected through threaded engagement until the bottom of the sleeve 3 is pre-tightened to the upper end faces of the first metal plate 4 and the second metal plate 5.
[0030] Further optimized, a channel 1-1 is provided on the upper surface of the base plate 1 to increase the contact area between the structural adhesive and the upper surface of the base plate 1. On the other hand, the top opening of the channel 1-1 is constricted, allowing the structural adhesive to hook onto the base plate 1 after semi-curing / curing. For example, the channel 1-1 has an arc structure, and the width of the opening of the channel 1-1 in the left-right direction is less than the maximum width of the channel 1-1 in the left-right direction.
[0031] To further optimize the process, the welding position between the column 2 and the base plate 1 can be concealed to keep the upper surfaces of the first metal plate 4 and the second metal plate 5 flat. A groove 1-2 can be provided on the upper surface of the base plate 1, and the column 2 can be placed in the groove 1-2. In this way, the weld bead is placed inside the groove 1-2 and does not protrude from the upper surface of the base plate 1.
