Description

Technical Field

[0001] This utility model belongs to the field of steel structure construction technology, and in particular relates to a high-altitude adjustment device for tubular trusses. Background Technology

[0002] Steel structures are widely used in the construction industry due to their advantages such as high strength, relatively small mass, good seismic resistance, beautiful appearance, and fast construction speed. Because of their large span and heavy individual components, they are usually installed by on-site assembly and overall hoisting. Tubular trusses are a commonly used structural form in steel structures. They are truss structures made of steel pipes connected by welding or bolting. In the current technology, after the tubular truss is hoisted to a high altitude, the position of the whole component needs to be adjusted using traction ropes. This method often requires multiple people to work together, which not only has poor stability and low construction efficiency, but also has high manual operation difficulty and low adjustment accuracy, increasing the high-altitude operation risk and construction cost of tubular truss installation.

[0028] The embodiments of this utility model will now be described with reference to the accompanying drawings.

[0029] This utility model proposes a high-altitude adjustment device for tubular trusses, which solves the problem of difficulty in efficiently and accurately adjusting the height of tubular trusses after they are hoisted to a high altitude. It reduces the difficulty of operation, improves the installation efficiency of tubular trusses, and helps to ensure the safety of high-altitude operations.

[0030] like Figures 1 to 3As shown in the embodiment of this application, a high-altitude adjustment device for a tubular truss is proposed, including a support frame 1. The support frame 1 includes an upper crossbeam 11 and a lower crossbeam 12 arranged horizontally. The upper crossbeam 11 is provided with an adjustable support mechanism 2 for supporting the upper chord 3 of the tubular truss, and the lower crossbeam 12 is provided with an adjustable support mechanism 2 for supporting the lower chord 4 of the tubular truss. The adjustable support mechanism 2 includes a lifting component 22 for adjusting the height of the tubular truss. The support frame 1 is located below the intended installation position of the tubular truss. The tubular truss in this application can be an equilateral triangular truss structure, an inverted triangular truss structure, or other structural forms. The equilateral triangular truss structure and the inverted triangular truss structure both include an upper chord 3, a lower chord 4, and web members. There are three upper chords 3 and three lower chords 4, which are arranged in parallel to form a spatial triangular distribution. The web members are connected to the three. Based on the structural characteristics of the tubular truss, the position and height of the adjustable support mechanism 2 on the upper beam 11 and lower beam 12 can match the structure of the tubular truss and the positional relationship between the upper chord 3 and the lower chord 4. During use, the tubular truss and the adjustable support mechanism 2 can make full contact, and the adjustable support mechanism 2 has sufficient stability and rigidity to provide stable support for the tubular truss. By adjusting any one of the adjustable support mechanisms 2, the height of the upper chord 3 or the lower chord 4 located on that adjustable support mechanism 2 can be adjusted, thereby adjusting the overall posture of the tubular truss. Alternatively, by simultaneously adjusting multiple adjustable support mechanisms 2, the overall height of the tubular truss can be adjusted after the posture of the tubular truss meets the requirements. This structure is simple and reasonable, easy to operate, and has good adjustment accuracy and safety.

[0031] Furthermore, such as Figure 1 As shown, the support frame 1 also includes columns. The upper crossbeam 11, the lower crossbeam 12 and the columns are connected to each other to form an integral structure, which has good stability and support capacity. Preferably, the support frame 1 is made of H-beams, I-beams or other types of steel, which has high strength and rigidity, can withstand large loads, and is easy to process and manufacture.

[0032] In one embodiment of this application, such as Figure 2 As shown, the adjustable support mechanism 2 also includes a base 23 and a support 21. The base 23 is detachably mounted on the upper crossbeam 11 and the lower crossbeam 12. The lifting assembly 22 is mounted on the base 23 and includes a driver and a vertically mounted lifting rod 221. The support 21 is mounted on the top of the lifting rod 221 and has a support portion that matches the upper chord 3 and the lower chord 4.

[0033] In the above embodiments, the base 23 can be fixed to the upper crossbeam 11 or the lower crossbeam 12 by bolt connection, or it can be connected by clamps or buckles, which is not limited here; the base 23 is a steel plate with a set thickness, and the shape of the base 23 can be circular or square. When the base 23 is installed on the upper crossbeam 11 or the lower crossbeam 12, it will not protrude to the outside of the upper crossbeam 11 or the lower crossbeam 12; preferably, the size of the base 23 is made according to the shape of the upper end face of the upper crossbeam 11 or the lower crossbeam 12, so that the base 23 and the upper crossbeam 11 or the lower crossbeam 12 have sufficient contact area to improve its stability and anti-overturning ability.

[0034] In the above embodiment, the driver is fixed on the base 23, and the lifting rod 221 is connected to the driving end of the driver. It can rise or fall under the drive of the driver to achieve precise adjustment of the height of the support 21, thereby achieving adjustment of the height of the upper chord 3 or the lower chord 4. The driver can be a chain drive, a gear and rack drive, a cylinder, or other lifting device, which can be selected according to actual needs. No specific requirements are made here. In a preferred embodiment, the driver is a jack, which is a commercially available product. Its bottom end is fixed on the base 23 and is installed synchronously on the upper crossbeam 11 or the lower crossbeam 12 along with the base 23.

[0035] In the above embodiment, the support seat 21 is disposed at the top of the lifting rod 221, and the support part has an upward opening so that the upper chord 3 or the lower chord 4 can be fixed on the support seat 21 through the opening; the shape of the support part is made according to the cross-sectional shape of the upper chord 3 or the lower chord 4; when the cross-section of the upper chord 3 or the lower chord 4 is circular, the support part has an arc surface that matches the circular shape and size. Preferably, the support part has a semi-circular arc surface, which can limit the upper chord 3 or the lower chord 4 while supporting it; when the cross-section of the upper chord 3 or the lower chord 4 is square, the support part has a bottom surface and a side surface that match the square shape and size.

[0036] In one specific embodiment, the support 21 is made of steel plate and the lifting rod 221 is made of steel pipe, and the two are fixed by welding.

[0037] Furthermore, in this embodiment, the center of the support part in the vertical direction coincides with the axis of the lifting rod 221, so that the load transmitted by the upper chord 3 or the lower chord 4 can be transmitted downward in the vertical direction, so as to avoid generating eccentric loads and affecting the stability of the overall device.

[0038] Furthermore, in this embodiment, the axis of the supporting part along the horizontal direction is perpendicular to the upper crossbeam 11 and the lower crossbeam 12. That is, when the tubular truss is placed on the adjustable support mechanism 2, the length direction of the tubular truss is perpendicular to the upper crossbeam 11 and the lower crossbeam 12. The length direction of the tubular truss is supported by several sets of upper crossbeams 11, lower crossbeams 12 and the adjustable support mechanism 2. Compared with the upper crossbeams 11 and lower crossbeams 12 being arranged along the length direction of the tubular truss, this technical solution reduces the length of the upper crossbeams 11 and lower crossbeams 12, which not only facilitates processing and manufacturing but also makes the arrangement of the upper crossbeams 11 and lower crossbeams 12 more flexible and better adaptable to different working space conditions.

[0039] In the above embodiments, both the upper crossbeam 11 and the lower crossbeam 12 are provided with several mounting positions. The adjustable support mechanism 2 can be selectively fixed in different mounting positions, so that the adjustable support mechanism 2 can be installed in different positions of the upper crossbeam 11 or the lower crossbeam 12 as needed to better adapt to space requirements. The relative position of the adjustable support mechanism 2 can also be adjusted according to the specifications of the tubular truss, so that the adjustable support mechanism 2 can be matched with tubular trusses of different specifications, thus expanding the scope of application of this application.

[0040] In one alternative technical solution, the upper crossbeam 11 and the lower crossbeam 12 are arranged in parallel to each other to support the two ends of the tubular truss. That is, the upper crossbeam 11 and the lower crossbeam 12 are set in two groups, and the adjustable support mechanism 2 is also set in two corresponding groups, which are respectively supported at the two ends of the tubular truss. The spacing between the two groups of adjustable support mechanisms 2 is matched with the protruding length of the upper chord 3 and the lower chord 4 at both ends of the tubular truss. During installation, one end of the tubular truss is first placed on a set of support seats 21, and then the tubular truss is moved towards the other end so that the upper chord 3 and the lower chord 4 pass through the other set of support seats 21 respectively. Then, the two groups of adjustable support mechanisms 2 are adjusted synchronously to complete the precise adjustment of the height of the tubular truss.

[0041] In a specific embodiment, such as Figure 1 As shown, the tubular truss is an inverted triangular truss structure, including two upper chords 3 and one lower chord 4; each set of adjustable support mechanisms 2 consists of three, of which two adjustable support mechanisms 2 are fixed on the upper crossbeam 11 at a set interval, and the other adjustable support frame 1 is set on the lower crossbeam 12. The horizontal distance between the three adjustable support mechanisms 2 is the same as the horizontal distance between the two upper chords 3 and one lower chord 4 of the tubular truss.

[0042] In another alternative technical solution, there are two upper crossbeams 11, which are used to support the two ends of the tubular truss; there are multiple lower crossbeams 12, which are spaced apart, used to support the middle part of the tubular truss or simultaneously support the two ends and the middle part of the tubular truss; preferably, the lower crossbeams 12 are evenly arranged along the length of the tubular truss; that is, the upper chord 3 is supported by the support seats 21 on the two upper crossbeams 11, while the lower chord 4 is supported by the support seats 21 on the multiple lower crossbeams 12; this technical solution significantly improves the load-bearing capacity of the overall device compared to setting both the upper crossbeams 11 and the lower crossbeams 12 at both ends of the tubular truss.

[0043] Furthermore, in the embodiments of this application, such as Figure 2 and Figure 3 As shown, the adjustable support mechanism 2 also includes a housing 24, with the driver disposed inside the housing 24, and the lifting rod 221 moving through the housing 24. By setting the housing 24, protection is formed for the lifting assembly 22 inside it, ensuring the stable operation of the lifting assembly 22 and making it less susceptible to external environmental influences.

[0044] In the above embodiment, the driver is provided with a hand crank 222 for adjusting the height of the lifting rod 221; the housing 24 has an operating port at the part corresponding to the hand crank 222; preferably, the driver adopts a hand-cranked jack, which adjusts the lifting rod 221 up or down by hand cranking force, which is simple, flexible and reliable to operate, and also easier to make precise control to ensure the accuracy of adjustment; the above-mentioned operating port is large enough so that construction personnel can easily crank the hand crank 222;

[0045] Furthermore, to further improve the stability of the adjustable support mechanism on the upper crossbeam 11 and the lower crossbeam 12, a reinforcing member 25 is provided on the outer bottom of the outer shell 24. Preferably, the reinforcing member 25 is evenly distributed at the bottom of the outer shell 24 and is a triangular plate structure.

[0046] This application also proposes a construction method using the above-mentioned high-altitude adjustment device for tubular trusses, which improves the efficiency and accuracy of high-altitude adjustment of tubular trusses, is convenient and easy to control, reduces the difficulty of operation, and enhances the safety of high-altitude operations; including the following steps:

[0047] S1. Fabricate support frame 1 according to the shape and location of the tubular truss to be installed;

[0048] Specifically, this includes installing the support frame 1 below the intended installation position of the tubular truss; setting two upper crossbeams 11 and two or more lower crossbeams 12; setting the installation height of the upper crossbeams 11 and lower crossbeams 12 according to the vertical distance between the upper chord 3 and the lower chord 4 of the tubular truss; and setting the spacing between the upper crossbeams 11 and the spacing between the lower crossbeams 12 according to the length of the tubular truss.

[0049] S2. Fix the adjustable support mechanism 2 to the support frame 1;

[0050] Specifically, when the tubular truss is an inverted triangular truss structure, two adjustable support mechanisms 2 are fixed to the upper crossbeam 11 at a set interval, and another adjustable support frame 1 is set on the lower crossbeam 12. The horizontal distance between the three adjustable support mechanisms 2 matches the horizontal distance between the two upper chords 3 and one lower chord 4 of the tubular truss. When the tubular truss is an equilateral triangular truss structure, two adjustable support mechanisms 2 are fixed to the lower crossbeam 12 at a set interval, and another adjustable support frame 1 is set on the upper crossbeam 11. The horizontal distance between the three adjustable support mechanisms 2 matches the horizontal distance between the two upper chords 3 and one lower chord 4 of the tubular truss.

[0051] S3. Adjust the height of the support parts so that the relative positions between the support parts are the same as the relative positions of the upper chord 3 and the lower chord 4 of the tubular truss.

[0052] The purpose of the above technical solution is to make preliminary adjustments to the height of the support, so that the tubular truss can be placed on the adjustable support mechanism 2 and the adjustable support mechanism 2 can make full contact with the tubular truss. This avoids the situation where some adjustable support mechanisms 2 cannot provide support while others are overloaded, ensuring that the tubular truss receives uniform and sufficient support force, so that the tubular truss can be stably fixed on the adjustable support mechanism 2 after it is removed from the hoisting equipment.

[0053] S4. Place the tubular truss in the support section;

[0054] After the tubular truss is assembled on the ground, it can be placed on the support of the adjustable support mechanism 2 using hoisting equipment such as tower cranes.

[0055] S5. Adjust the height of the support section to ensure that the height of the tubular truss meets the design requirements.

[0056] Preferably, the same number of operators are set up to adjust the number of adjustable support mechanisms 2 as needed, and adjust the lifting assembly 22 synchronously and in the same direction so that all parts of the truss are raised or lowered synchronously to meet the design height requirements.
