Description

Technical Field

[0001] This utility model belongs to the field of construction equipment, and specifically relates to an adjustable assembly jig device for adjusting the position of ring-shaped assembly components. Background Technology

[0002] With the promotion of national fitness programs, the demand for sports venues is constantly increasing. In recent years, the scale and number of sports venues have shown a significant growth trend. When designing and constructing sports venues, elliptical ring-shaped steel structure roofs are widely used to meet the requirements of large spans and a simple, aesthetically pleasing appearance. However, these large-span steel structure roofs are difficult to install as a whole and are usually constructed using segmented installation methods or high-altitude assembly methods.

[0003] While the modular installation method allows large structures to be broken down into smaller units for hoisting, it is unsuitable for projects with limited space, as it requires significant space for component storage and hoisting equipment operation. The high-altitude assembly method involves first assembling the structure on temporary supports before installing the entire structure. Although this method has lower space requirements, it presents numerous technical challenges during actual construction due to inconsistent design elevations and structural unit heights in the elliptical ring roof structure, as well as extremely high installation precision requirements. When using existing conventional supports for assembly, adjusting the structural elevation typically relies on manual adjustments using short columns, increasing the workload for workers and making it difficult to guarantee installation accuracy. This can lead to problems such as misalignment and incomplete closure of the ring structure during installation.

[0004] Therefore, developing a jig device that can effectively adjust the position of ring-shaped assembly components to improve installation accuracy, reduce labor intensity, and ensure construction quality and safety is of great practical significance and has broad application prospects for promoting the development of sports stadium construction technology.

[0019] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below. Technical features in various embodiments of this utility model can be combined appropriately without conflict.

[0020] In the description of this utility model, it should be understood that the terms "first" and "second" are used only for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include at least one of those features.

[0021] As a preferred embodiment of this utility model, this embodiment provides an adjustable assembly frame device for adjusting the position of annular assembly components, including a supporting frame structure 2, a horizontal adjustment structure 3, and a vertical adjustment structure 4, as shown in the specific structure below. Figure 1 and Figure 2 As shown.

[0022] The supporting frame structure 2 includes supporting frames 21 on both sides and a top beam 22 vertically fixed between the supporting frames 21. In this embodiment, the top beam 22 is made of I-beam, which consists of an upper flange, a lower flange, and a web vertically disposed between the upper and lower flanges. The supporting frame structure 2 in this embodiment has two top beams 22, each top beam 22 having a set of horizontal adjustment structures 3 and vertical adjustment structures 4. Each set of vertical adjustment structures 4 includes a bracket base 41, several vertical adjustment rods 42, and vertical fixing members 43; each set of horizontal adjustment structures 3 includes an arc bracket 31, several horizontal adjustment rods 32, and horizontal fixing members 33.

[0023] like Figure 2 As shown, in the structure provided by this utility model, several vertical through holes for the vertical adjusting rods 42 are provided on both the upper and lower flanges of the top beam 22. These vertical through holes are spaced apart along the length of the top beam 22. In this embodiment, two rows of vertical through holes are provided on the upper flange of the top beam 22, with 10 vertical through holes in each row. The lower flange of the top beam 22 also has corresponding vertical through holes as on the upper flange. In practical applications, those skilled in the art can also provide stiffening plates between the upper and lower flanges of the top beam 22 to ensure the strength and stability of the supporting frame structure 2.

[0024] In the structure provided by this utility model, the vertical adjusting rod 42 is vertically installed in the vertical through holes of the upper and lower flanges of the top beam 22, and both ends of the vertical adjusting rod 42 are provided with external threads of a certain length. The vertical adjusting rod 42 can be made of solid steel bar, and both ends of the solid steel bar are provided with external threads of a certain length. The vertical fixing member 43 is sleeved on both ends of each vertical adjusting rod 42, and the vertical fixing member 43 is a nut that matches the external threads at both ends of the vertical adjusting rod 42. The bracket base 41 includes a horizontal plate at the bottom and vertical plates that are vertically fixed to both ends of the horizontal plate. The bottom of the bracket base 41 is fixedly connected to the top of all the vertical adjusting rods 42. In this embodiment, the bracket base 41 is made of three steel plates, and the two ends of the horizontal steel plate are vertically fixed to two vertical steel plates by welding to form a groove structure for placing the arc bracket 31. The arc bracket 31 is used to place the annular steel pipe beam segment 1 to be installed. The height of the bracket base 41 is adjusted by rotating the vertical fixing component 43, thereby adjusting the height of the annular steel pipe beam segment 1 to be installed on the arc bracket 31.

[0025] In the structure provided by this utility model, several horizontal adjustment rods 32 are respectively provided at both ends of the arc bracket 31. Horizontal through holes for the horizontal adjustment rods 32 are opened on the vertical plates at both ends of the bracket base 41. In this embodiment, two horizontal through holes are opened on each side of the vertical plate. One end of the horizontal adjustment rod 32 is fixedly connected to the side wall of the arc bracket 31, and the other end passes through the horizontal through hole, and this end has a certain length of external thread. The horizontal adjustment rod 32 can also be a solid steel rod, with an external thread at the end of the solid steel rod away from the arc bracket 31. A horizontal fixing member 33 is sleeved on the end of the horizontal adjustment rod 32 that protrudes from the vertical plate. The horizontal fixing member 33 uses a nut that matches the external thread on the horizontal adjustment rod 32. The horizontal position of the arc bracket 31 is adjusted by rotating the horizontal fixing member 33.

[0026] It should be noted that the support frame structure 2 provided by this utility model is provided with at least two sets of horizontal adjustment structures 3 and vertical adjustment structures 4 at its top. Those skilled in the art can set appropriate numbers of horizontal adjustment structures 3 and vertical adjustment structures 4 according to the mass and size of the ring-shaped steel pipe beam segments to be installed as needed. In this embodiment, each set of vertical adjustment structures 4 is provided with 20 vertical adjustment rods 42. It should be noted that the number of vertical adjustment rods 42 and vertical fixing parts 43 can be reduced as appropriate to reduce workload while ensuring the accuracy of vertical position adjustment. In this embodiment, each set of horizontal adjustment structures 3 has 2 horizontal adjustment rods 32 on one side of the arc bracket 31.

[0027] In the structure provided in this embodiment, the upper surface of the arc bracket 31 is set with an arc that matches the segment 1 of the annular steel pipe beam. The arc bracket 31 is welded together from two steel plates with arc notches and a connecting steel plate. The arc of the arc notches must be larger than that of the annular steel pipe beam to facilitate the embedding of components and prevent the annular steel pipe beam from rolling.

[0028] It should be noted that the shape of the arc bracket can be optimized according to actual needs to improve its functionality and safety. For example, the sharp points on both sides of the arc bracket can be rounded to prevent hand injuries during handling; the curvature of the arc notch can be designed to be gentler to accommodate the assembly of more round tubes of different diameters; the arc bracket can be optimized into a non-arc bracket with adjustable edge distances. This design can not only fix round tube components, but also accommodate box-shaped or other cross-sectional shapes of members.

[0029] The adjustable assembly jig device provided in this embodiment also includes a support assembly jig 6 for supporting other members of the unit where the annular steel pipe beam segment 1 is located; the other members include uprights 51 connected to the annular steel pipe beam segment 1 and chord members 52, wherein the chord members 52 are arranged between the uprights 51. The support assembly jig 6 is welded into a whole by several H-beams. The support assembly jig 6 is also provided with adjusting short columns 7 for adjusting the elevation, which facilitates the support of lighter components with different elevations. This setting adopts a relatively conventional design in the art, therefore, this utility model does not specifically limit the specific structure of the support assembly jig 6, and those skilled in the art can set it according to actual needs.

[0030] Next, this embodiment also provides a method for using the above-mentioned adjustable assembly frame device, the specific steps of which are as follows: Step 1: Construction Preparation Erect the assembly platform. Transport the ring steel pipe beam segment 1, as well as uprights 51 and chord members 52, to the construction site. Use lifting equipment to hoist the ring steel pipe beam segment 1, uprights 51, and chord members 52 onto the assembly platform.

[0031] Step 2: Positioning and Installing the Mounting Frame Check and confirm the assembly points are correct according to the construction drawings. Place and install the adjustable assembly jig and the supporting assembly jig 6. Install the horizontal adjustment structure 3 and the vertical adjustment structure 4 on the supporting jig structure 2 of the adjustable assembly jig and make preliminary adjustments to the elevation.

[0032] Step 3: Install and adjust the segments of the ring-shaped steel pipe beam. The annular steel pipe beam is divided into two segments: a first annular steel pipe beam 11 and a second annular steel pipe beam 12, which need to be connected. The first annular steel pipe beam 11 and the second annular steel pipe beam 12 are hoisted onto their corresponding arc-shaped brackets 31, ensuring that their bottoms are directly supported by the arc-shaped brackets 31. Figure 3 and Figure 4As shown.

[0033] Since the directly placed segments of the annular steel pipe beam typically have positional deviations, direct welding connections between segments are not possible. Therefore, horizontal and vertical adjustments are necessary: ​​First, rotate the horizontal fixing part 33 on the horizontal adjusting rod 32, causing the arc bracket 31 and the annular steel pipe beam segment 1 on it to move horizontally, achieving a fine adjustment of the horizontal position of the annular steel pipe beam segment 1. Then, rotate the vertical fixing parts 43 at both ends of the vertical adjusting rod 42, causing the bracket base 41 to drive the arc bracket 31 and the annular steel pipe beam segment 1 on it to move vertically, achieving a fine adjustment of the vertical position of the annular steel pipe beam segment 1. After adjustment, tighten the horizontal fixing part 33 and the vertical fixing part 43 to prevent displacement that could cause positional deviations.

[0034] Step 4: Welding the segmented ring-shaped steel pipe beam After the position adjustment is completed, welding connection is performed at the interface where the first annular steel pipe beam 11 and the second annular steel pipe beam 12 are aligned.

[0035] Step 5: Assemble other rod components like Figure 5 As shown, the uprights 51 and chord members 52 are hoisted onto the corresponding support assembly jigs 6. After adjusting the elevation, the uprights 51 are first connected to the ring steel pipe beam segment 1, then the chord members 52 between the uprights 51 are connected, and finally the lower chord members 52 are connected until the welding assembly of this unit is completed. During the assembly of these members, the elevation is adjusted and the position is fixed by adjusting the short columns 7.

[0036] Step Six: Overall Assembly After welding and assembling multiple structural units, lifting machinery is used to hoist the assembled structural units and place them on the construction platform. On the construction platform, the units are aligned and welded together, and then connected and closed in sequence to finally complete the installation of the entire elliptical ring steel structure roof.

[0037] The embodiments described above are merely preferred solutions of this utility model, and are not intended to limit the scope of this utility model. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this utility model. Therefore, all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of this utility model.
