Description

Technical Field

[0001] This invention relates to a building structure keel system, and more particularly to a concealed double-core keel system. Background Technology

[0002] In the construction industry, keel systems typically consist of aluminum columns and steel beams. Specifically, the aluminum columns and steel beams are connected using a continuous steel sleeve; that is, after the steel sleeve is connected to the aluminum column with bolts or self-tapping screws, it is then fixed to the steel beam by welding. However, practical implementation reveals several drawbacks of this traditional connection method: First, it requires high-altitude automated welding operations on-site, resulting in low construction safety. Furthermore, the welding process involves subsequent steps such as spraying the weld seams, which is cumbersome, inefficient, and time-consuming. Second, the steel sleeve's welded fixation to the steel beam prevents adjustment, leading to low assembly precision and limited adaptability of the entire keel system. Summary of the Invention

[0003] The purpose of this invention is to provide a concealed double-core keel system, which solves the problems of low construction safety, cumbersome procedures, low assembly accuracy, and low adaptability of existing keel systems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A concealed double-core keel system includes steel beams and aluminum columns. The aluminum columns are fixed between two adjacent steel beams. The upper and lower ends of the aluminum columns are fixed to the steel beams by double-core components. The double-core components include a frame-shaped core made of aluminum alloy and a U-shaped core made of aluminum alloy. The U-shaped core is fixed to the frame-shaped core inserted into the port of the aluminum column by fasteners. The frame-shaped core is fixed to the aluminum column by a steel pin connection assembly. The U-shaped core located inside the frame-shaped core is fixed to the steel beam by a stainless steel bolt assembly.

[0006] The advantages of this invention are:

[0007] In this invention, the connection between the aluminum column and the steel beam does not require welding. The two are connected by two aluminum alloy core sleeves, which solves the problems of low construction safety caused by high-altitude welding and cumbersome procedures caused by post-weld processing. Construction efficiency is improved, and the aluminum column and steel beam can be flexibly adjusted in six directions in three dimensions, which improves the assembly accuracy. The adaptability of the entire keel system is greatly improved, and the invention is low in cost and suitable for widespread application. Attached Figure Description

[0014] The concealed double-core keel system of the present invention includes steel beams (such as right-angle steel beams) 10 and aluminum columns (aluminum alloy columns) 20. The aluminum columns 20 are fixed between two adjacent steel beams 10, such as... Figures 1 to 6 As shown, the upper and lower ends of the aluminum column 20 are fixed to the steel beam 10 by a double-core component. The double-core component includes a frame-type core 40 made of aluminum alloy and a U-shaped core 30 made of aluminum alloy. The U-shaped core 30 is fixed to the frame-type core 40 inserted into the port of the aluminum column 20 by fasteners 35. That is, the frame-type core 40 is hidden inside the port of the aluminum column 20. The frame-type core 40 is fixed to the aluminum column 20 by a steel pin connection assembly 60. The U-shaped core 30, which is inside the frame-type core 40, is fixed to the steel beam 10 by a stainless steel bolt assembly 50. That is, the U-shaped core 30 is hidden inside the frame-type core 40. The double-core component is completely hidden inside the aluminum column 20.

[0015] like Figure 4 The frame-type sleeve 40 is rectangular and its shape matches the inner cavity shape of the aluminum column 20. The frame-type sleeve 40 is not continuous within the aluminum column 20, but only near the end of the aluminum column 20. Additionally, the U-shaped sleeve 30 has a U-shaped cross-section, and the frame-type sleeve 40 is fitted over the U-shaped sleeve 30. Figure 1 .

[0016] like Figures 3 to 6 The frame-shaped sleeve 40 has a second fastening hole 401, and the U-shaped sleeve 30 has a first fastening hole 302. The frame-shaped sleeve 40 and the U-shaped sleeve 30 are fixed together by fasteners (such as stainless steel pan head machine screws) 35 that pass through and are installed in the second fastening hole 401 and the first fastening hole 302. The fasteners 35 are installed on the front side wall of the aluminum column 20, i.e., on the outdoor side. Figure 1As shown, the front side wall of the aluminum column 20 has a front notch 21 for accommodating the fastener 35.

[0017] During actual installation, after the U-shaped sleeve 30 is positioned on the steel beam 10 by the bolt assembly 50, the frame sleeve 40 is inserted into the port of the aluminum column 20 and is in an active state. By pushing the aluminum column 20 with the frame sleeve 40 inserted, the U-shaped sleeve 30 passes through the front notch 21 and is placed in the frame sleeve 40 inside the aluminum column 20. When the U-shaped sleeve 30 is in the frame sleeve 40 inside the aluminum column 20, the frame sleeve 40 is brought close to or in contact with the steel beam 10 to fit the U-shaped sleeve 30, and the U-shaped sleeve 30 and the frame sleeve 40 are fixed by the fastener 35.

[0018] like Figure 1 and Figure 6 For the upper end of the aluminum column 20, a vertical elongated hole 22 is provided on the front side wall of the aluminum column 20 for accommodating a limiting component (such as a stainless steel pan head self-tapping screw) 36. A limiting hole (not shown in the figure) is provided on the frame-shaped sleeve 40. The limiting component 36 passes through the vertical elongated hole 22 and is installed in the limiting hole. The purpose of the structural design of the limiting component 36 and the vertical elongated hole 22 is to limit the frame-shaped sleeve 40 when the aluminum column 20 with the frame-shaped sleeve 40 inserted is pushed towards the U-shaped sleeve 30, so as to prevent the frame-shaped sleeve 40 from falling off during the pushing process.

[0019] During actual installation, when pushing the aluminum column 20, which has the frame sleeve 40 inserted, towards the lower end of the U-shaped sleeve 30, the frame sleeve 40 can be lifted directly by hand or with a tool to limit its movement. Alternatively, the frame sleeve 40 can be temporarily fixed to the aluminum column 20 using temporary fasteners so that it does not obstruct the U-shaped sleeve 30 from passing through the front notch 21.

[0020] like Figure 5 The pin connection assembly 60 includes a pin 61 and a pin locking fastener 62. The frame-type sleeve 40 and the aluminum column 20 are each provided with pin holes 402 and 23. The pin 61 passes through the pin holes 23 and 402 on the aluminum column 20 and the frame-type sleeve 40 and is fixed to the pin locking fastener 62 by a locking component (not shown in the figure, such as a pan head self-tapping screw), thereby realizing the fixation between the aluminum column 20 and the frame-type sleeve 40.

[0021] Preferably, the pin holes 23 on the aluminum column 20 are pre-drilled before the aluminum column 20 is installed, and the pin holes 402 on the frame sleeve 40 are drilled on-site according to the position requirements of the aluminum column 20 when the frame sleeve 40 is installed, so that the aluminum column 20 can be adjusted up and down relative to the steel beam 10 by drilling the pin holes 402 on the frame sleeve 40 on-site.

[0022] like Figure 1 , Figure 3 The bolt assembly 50 includes a bolt 51, a nut 52, an upper washer 53, and a lower washer 54. The bolt 51 passes through the U-shaped sleeve 30 on the steel beam 10, the steel beam 10, and the U-shaped sleeve 30 below the steel beam 10 in the vertical direction and is then locked and fixed by the nut 52. The upper washer 53 is located between the bolt head of the bolt 51 and the U-shaped sleeve 30 on the steel beam 10. The lower washer 54 is located between the U-shaped sleeve 30 below the steel beam 10 and the nut 52.

[0023] Furthermore, such as Figure 3 and Figure 4 The U-shaped sleeve 30 has a longitudinally adjustable elongated hole 301 for the bolt 51 to pass through. The longitudinally adjustable elongated hole 301 is arranged in the longitudinal direction. The U-shaped sleeve 30 has serrations 303 around the longitudinally adjustable elongated hole 301. The side of the upper washer 53 that contacts the U-shaped sleeve 30 and the side of the lower washer 54 that contacts the U-shaped sleeve 30 also have serrations (not shown in the figure). In this invention, the longitudinally adjustable elongated hole 301 is designed to allow for the forward and backward adjustment of the aluminum column 20 by adjusting the U-shaped sleeve 30 in the longitudinal direction. The serrations 303 around the longitudinally adjustable elongated hole 301 on the U-shaped sleeve 30, as well as the serrations on the upper washer 53 and the lower washer 54, are designed to improve the locking and positioning effect.

[0024] like Figure 3 Furthermore, the steel beam 10 is provided with a transversely adjustable elongated hole 11 for the bolt 51 to pass through, and the transversely adjustable elongated hole 11 is arranged in the transverse direction. In this invention, the purpose of the transversely adjustable elongated hole 11 is to achieve the left and right adjustment of the aluminum column 20 by adjusting the U-shaped sleeve 30 in the transverse direction.

[0025] Of course, in actual design, the side of the U-shaped sleeve 30 facing the horizontal adjustment elongated hole 11 and the side around the horizontal adjustment elongated hole 11 can also be provided with serrations (not shown in the figure), thereby improving the locking and positioning effect based on the serration design.

[0026] In the actual design, the U-shaped core 30 is formed by connecting a horizontal plate 31 and two vertical plates 32. The horizontal plate 31 is used to set the longitudinal adjustment elongated hole 301 and the sawtooth 303, and the vertical plate 32 is used to set the first fastening hole 302.

[0027] In this invention, such as Figure 1The length direction of the steel beam 10 is defined as the transverse direction, and the direction perpendicular to the transverse direction in the horizontal plane is defined as the longitudinal direction, i.e., the longitudinal direction is the outdoor-indoor direction. The height direction of the aluminum column 20 is defined as the up-down direction. Adjustment in the transverse direction is also called left-right adjustment, and adjustment in the longitudinal direction is also called front-back adjustment. Therefore, the front-back, up-down, and other directions of the components and parts in this invention are defined accordingly based on the above-mentioned direction definitions.

[0028] During installation, the U-shaped sleeve 30 is first fixed to the steel beam 10. During this fixing process, the U-shaped sleeve 30 can adjust its position on the steel beam 10 laterally via the horizontal adjustment hole 11 (left-right adjustment), and it can also adjust its position longitudinally via the vertical adjustment hole 301 (front-back adjustment). This allows for both left-right and front-back adjustments of the aluminum column 20 relative to the steel beam 10. Once adjusted, the bolt assembly 50 is tightened to fix the U-shaped sleeve 30 to the steel beam 10. Then, a frame-shaped sleeve 40 is inserted into each of the upper and lower ends of the aluminum column 20, ensuring the frame-shaped sleeves 40 are movable. The aluminum column 20 with the inserted frame-shaped sleeves 40 is then pushed, causing the corresponding U-shaped sleeves 30 at the upper and lower ends of the aluminum column 20 to pass through the corresponding front notches 21 on the aluminum column 20. After the U-shaped sleeve 30 is fitted inside the frame-shaped sleeve 40 in the aluminum column 20, the frame-shaped sleeve 40 is brought close to or in contact with the steel beam 10, so that the U-shaped sleeve 30 is fitted inside the frame-shaped sleeve 40. Then, the frame-shaped sleeve 40 and the U-shaped sleeve 30 are fixed together by fasteners 35. Finally, the frame-shaped sleeve 40 is fixed to the aluminum column 20 by the pin connection assembly 60, thus completing the installation of the keel system of the present invention.

[0029] Before inserting the frame sleeve 40 into the aluminum column 20, the pin holes 402 should be prepared on the frame sleeve 40 on site according to the installation requirements of the upper and lower positions of the aluminum column 20.

[0030] Once the keel system of this invention is installed, subsequent processes can be carried out, such as the installation of the glass panel 80 and the aluminum alloy decorative strip 90. Figure 1 The aluminum alloy adapter 71 is fixed to the front end face of the steel beam 10 via the adapter fastener 73. Then, the aluminum alloy base 72 is fixed to the adapter 71 using screws or other fasteners. The glass panel 80 can then be installed between two adjacent bases 72. After the glass panel 80 is installed, the decorative strip 90 can be installed. The installation structure and process of the glass panel 80 and the decorative strip 90 are well-known techniques in the art.

[0031] In this invention, the connection between the aluminum column and the steel beam does not require welding. The two are connected by two aluminum alloy cores (U-shaped core 30 and frame-shaped core 40), which solves the problems of low construction safety caused by high-altitude welding and cumbersome procedures caused by post-weld processing. Construction efficiency is improved, and the aluminum column and steel beam can be flexibly adjusted in six directions in three dimensions, which improves the assembly accuracy. The adaptability of the entire keel system is greatly improved, and the invention is low in cost and suitable for widespread application.

[0032] The above description describes the preferred embodiments of the present invention and the technical principles applied thereto. For those skilled in the art, any obvious changes such as equivalent transformations or simple substitutions based on the technical solutions of the present invention, without departing from the spirit and scope of the present invention, shall fall within the protection scope of the present invention.
