Abstract
Description
Technical Field
[0001] This application relates to the field of steel structure technology, and in particular to a flange connection structure and an elevator shaft. Background Technology
[0002] Elevator shaft structures are typically rectangular steel frames formed by overlapping H-beams. To ensure structural safety and reliability, the joints of these H-beams were traditionally connected by welding or bolting during construction. Specifically, this required welding or bolting on multiple surfaces of the H-beam webs and flanges, which was inconvenient. Consequently, construction work needed to be carried out in multiple directions around the H-beams, requiring multiple work surfaces. Especially for high-altitude operations, scaffolding or ladder trucks were necessary because the H-beam joints required sufficient work surface space. This meant that the H-beam exterior cladding at these work surfaces could not be installed in advance, impacting the construction schedule. Utility Model Content
[0003] Therefore, it is necessary to provide a flange connection structure and elevator shaft to solve the problem that H-beam splicing joint nodes require multiple working surfaces, which leads to inconvenience in construction and affects the construction period.
[0004] A flange connection structure includes two H-shaped steel columns, with flanges connected to the ends of the H-shaped steel columns. The flanges have multiple connection holes for connecting parts to pass through. The flanges of the two H-shaped steel columns are joined together and fixedly connected by connecting parts. The H-shaped steel columns have webs, with multiple connection holes distributed on both sides of the webs. The webs also have operating holes that pass through both sides. One side of the webs is configured as a working surface, allowing construction personnel to install connecting parts through the operating holes on the working surface.
[0005] In one embodiment, the operating port is located near the flange, and at least a portion of the operating port extends through the edge of the web and extends to the flange surface.
[0006] In one embodiment, the operating hole is configured as a U-shaped hole or a semi-circular hole.
[0007] In one embodiment, the flange connection structure further includes a reinforcing member, and the H-shaped steel column also has two wing plates, which are respectively connected to the two ends of the web plate and form a first space and a second space on both sides of the web plate; the first space is configured with a working surface, the reinforcing member is set away from the working surface and connected to the two wing plates, and the operating hole connects the first space and the second space.
[0008] In one embodiment, at least some of the connection holes are located in a first space, and at least some of the connection holes are located in a second space; and the number of connection holes in the second space is less than the number of connection holes in the first space.
[0009] In one embodiment, the flange has a second protrusion located at the edge of the working surface extending from the H-shaped steel column, and at least part of the connection hole is formed in the second protrusion.
[0010] In one embodiment, at least some of the connection holes are located in a first space and at least some of the connection holes are located in a second space. The connection hole located in the second space is defined as the first hole. The first hole is located within the visible area formed by the opening edge of the first space and the operation hole. The visible area is the area where the space formed by the two sides of the opening end of the first space extending toward the opposite sidewall of the operation hole intersects with the second space.
[0011] In one embodiment, the connection hole located in the second space is defined as the first hole, and at least part of the projection of the first hole onto the web is located on the operating hole.
[0012] In one embodiment, the reinforcement is configured as a reinforcing plate, which is disposed corresponding to the operating hole and welded to the edges of the two wing plates.
[0013] In one embodiment, the flange docking structure further includes a locating pin. The flange has a first protrusion that extends beyond the edge of the H-shaped steel column, and a locating hole is provided on the first protrusion.

[0014] In one embodiment, the first protrusion extends out of one of the wing plates.
[0015] An elevator shaft comprising the flange connection structure described in any of the above embodiments.
[0016] Compared to existing technologies, the flange connection structure and elevator shaft provided in this application, with multiple connection holes distributed on both sides of the web, allow for the installation of through-holes in the web. This enables construction workers to assemble connectors and connection holes on one side of the web from the working face, and also to assemble connectors and connection holes on the other side of the web from the working face via the operating holes. In other words, the operating holes provide operating space for connectors and connection holes on the back of the web, eliminating the need for multiple working faces. Construction workers only need one working face to complete the connection and fixation of two H-shaped steel columns without having to move between multiple working faces. This facilitates construction operations, improves construction efficiency, accelerates the construction period, and saves labor and material costs. Attached Figure Description

[0027] To ensure structural safety and reliability, traditionally, H-beam splice joints were often constructed using welding or bolting. Specifically, this required welding or bolting on multiple surfaces of the H-beam web and flanges, which was inconvenient. Consequently, construction work needed to be carried out in multiple directions around the H-beam, requiring multiple work surfaces. Especially for high-altitude operations, scaffolding or ladders were necessary. Because the H-beam splice joints required sufficient work surface, the H-beam building's external cladding could not be installed in advance at these work surfaces, impacting the construction schedule.
[0028] Please see Figure 1 and Figure 2This application provides a flange docking structure 100, which includes two H-shaped steel columns 10. Flanges 12 are connected to the ends of the H-shaped steel columns 10. Multiple connection holes 121 are provided on the flanges 12 for connecting components to pass through. The flanges 12 of the two H-shaped steel columns 10 are docked and fixedly connected by connecting components. The H-shaped steel column 10 has a web 13, with multiple connection holes 121 distributed on both sides of the web 13. The web 13 also has operating holes 131 extending through both sides. One side of the web 13 is configured as a working surface 132, allowing construction personnel to install connecting components through the operating holes 131 on the working surface 132.
[0029] It is understandable that, since multiple connecting holes 121 are distributed on both sides of the web 13, by providing operating holes 131 that pass through both sides of the web 13, construction workers can assemble the connectors and connecting holes 121 on one side of the web 13 from the working surface 132, and can also assemble the connectors and connecting holes 121 on the other side of the web 13 from the working surface 132 via the operating holes 131. In other words, the operating holes 131 provide operating space for the connectors and connecting holes 121 on the back of the web 13, thereby eliminating the need for multiple working surfaces. Construction workers only need one working surface 132 to complete the connection and fixation of two H-shaped steel columns 10 without having to move between multiple working surfaces. This facilitates construction operations and improves construction efficiency, thereby accelerating the construction period and saving labor and material costs.
[0030] For example, when the flange connection structure 100 is applied to an elevator retrofit project in an existing building, the working surface can be set inside the shaft (i.e., the working surface can be set on the side of the H-shaped steel column facing the inside of the shaft), and the construction workers can stand inside the elevator shaft to complete the splicing of the H-shaped steel column.
[0031] The connector can be configured as a high-strength bolt, and each H-shaped steel column 10 is welded and fixed to the corresponding flange 12.
[0032] The operating hole 131 is located near the flange 12, and at least a portion of the operating hole 131 penetrates the edge of the web 13 and extends to the surface of the flange 12. It is understood that since the connection hole 121 is located on the web 13, by ensuring that at least a portion of the operating hole 131 penetrates the edge of the web 13 and extends to the surface of the flange 12—specifically, if the operating hole 131 penetrates the edge connecting the web 13 and the flange 12 and extends to the surface of the flange 12—it facilitates observation of the position of the connection hole 121 located on the back of the web 13 and reduces interference from the edge of the connection hole 121 to construction personnel.
[0033] For example, in one embodiment, the operating hole 131 is configured as a U-shaped hole. The length, width, and radius of the arc portion of the U-shaped hole can be specifically designed according to the specific number of connecting holes. Alternatively, in another embodiment, the operating hole 131 can also be configured as a semi-circular hole.
[0034] The H-shaped steel column 10 also has two wing plates 14, which are respectively connected to the two ends of the web plate 13, and form a first space 101 and a second space 102 on both sides of the web plate 13.
[0035] In one embodiment, the flange connection structure 100 further includes a reinforcing member 30. The first space 101 is configured with a working surface 132, and the reinforcing member 30 is positioned away from the working surface 132 and connected to two flanges 14. Since opening the operating hole 131 in the web 13 weakens the strength of the H-shaped steel column 10, the reinforcing member 30 strengthens the H-shaped steel column 10, thereby meeting the structural design strength requirements. Furthermore, the fact that the reinforcing member 30 is positioned away from the working surface 132 prevents it from interfering with construction workers' work.
[0036] Specifically, the reinforcing member 30 is configured as a reinforcing plate 31, which is correspondingly set with the operating hole 131 and welded to the edges of the two wing plates 14. That is, the reinforcing plate 31 is welded to fix the opening position of the second space 102.
[0037] In one embodiment, at least a portion of the connection hole 121 is located within the first space 101, and at least a portion of the connection hole 121 is located within the second space 102.
[0038] Optionally, in one embodiment, the number of connecting holes 121 in the second space 102 is less than the number of connecting holes 121 in the first space 101. This is beneficial because, while ensuring the stability and safety of the flange docking structure 100, the number of connecting holes 121 in the second space 102 is less than the number of connecting holes 121 in the first space 101, which is advantageous for improving construction efficiency, as construction personnel need to pass through the operating hole 131 to install the connectors and connecting holes 121 located in the second space 102.
[0039] In one embodiment, such as Figure 3As shown, the connecting hole 121 located within the second space 102 is defined as the first hole 121a. The first hole 121a is located within the visible area formed by the opening edge of the first space 101 and the operating hole 131. The visible area is the area where the space formed by the two sides of the opening end of the first space 101 extending towards the opposite sidewall of the operating hole 131 intersects with the second space 102. That is, the visible area formed by the opening edge of the first space 101 and the operating hole 131 refers to the maximum line of sight that a construction worker can see from the first space 101 through the operating hole 131 into the second space 102. Specifically, the visible area includes the area enclosed by the lines connecting the edge of one side wing plate 14 of the first space 101 to the edge of the opposite operating hole 131, and the line connecting the edge of the other side wing plate 14 of the first space 101 to the edge of the opposite operating hole 131, along the width direction of the web 13. The portion of this area that intersects with the second space 102 is the aforementioned visible area. Figure 3 The area shown in the cross-section. Thus, when construction workers perform construction operations on the working surface 132, the connecting holes 121 and connectors in the second space 102 will not be blocked by the web plate 13, thereby further facilitating the installation of connectors and connecting holes 121 located in the second space 102 by construction workers.
[0040] Optionally, in one embodiment, at least a portion of the projection of the first hole 121a onto the web 13 lies on the operating hole 131. For example, the entire projection of the first hole 121a onto the web 13 lies on the operating hole 131. That is, the first hole 121a is positioned corresponding to the location of the operating hole 131, facilitating more intuitive construction operations.
[0041] In one embodiment, the flange docking structure 100 further includes a locating pin 40. The flange 12 has a first protrusion 122 that extends beyond the edge of the H-shaped steel column 10, and a locating hole 123 is provided on the first protrusion 122. The flanges 12 of the two H-shaped steel columns 10 are positioned and engaged with the locating pin 40 and the locating hole 123. This facilitates quick positioning of the flanges 12 of the two H-shaped steel columns 10.
[0042] Furthermore, the first protrusion 122 extends out of one of the wing plates 14 on the outside of the wing plate 14, thus facilitating the assembly of the positioning pin 40 and the positioning hole 123 by the construction personnel on the working surface 132.
[0043] In one embodiment, the flange 12 has a second protrusion 124, which is provided on the edge of the working surface 132 extending out of the H-shaped steel column 10, and at least part of the connection hole 121 is formed in the second protrusion 124.
[0044] For example, in one embodiment, the number of connecting holes 121 is configured to be four, with one connecting hole 121 located in the second space 102 and two connecting holes 121 located in the first space 101. The connecting hole 121 in the second space 102 and the two connecting holes 121 in the first space 101 are distributed in an isosceles triangle. Furthermore, another connecting hole 121 is formed in the second protrusion 124. The connecting hole 121 on the second protrusion 124 is arranged side-by-side with the connecting hole 121 in the first space 101. However, this is not the only possibility; in other embodiments, the number and relative positions of the connecting holes 121 can be set according to actual needs.
[0045] The processing and assembly process of the flange docking structure 100 provided in this application is as follows: First, operating holes 131 are drilled at the joint of two H-shaped steel columns 10, and then flanges 12 are welded at the joint. After the flanges 12 are installed, the two H-shaped steel columns 10 can be docked and assembled at the steel structure factory or construction site. During docking, the two flanges 12 are first mated together using locating pins 40 and locating holes 123; then, high-strength bolts are passed through the connecting holes 121 and tightened to complete the joint splicing.
[0046] This application also provides an elevator shaft, which includes the flange docking structure 100 described in any of the above embodiments.
[0047] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0048] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
