Description

Technical Field

[0001] The utility model belongs to the technical field of steel structure installation, and in particular relates to a steel support hyperbolic truss assembly platform with adjustable size. Background Art

[0002] Truss: A structure made of rods connected to each other at both ends with hinges. A truss is a plane or space structure composed of straight rods, generally with triangular units. Truss rods mainly bear axial tension or pressure, so as to make full use of the strength of the material. When the span is large, it can save materials, reduce deadweight and increase rigidity compared to solid beams.

[0003] At present, domestic and foreign architecture no longer focuses on traditional horizontal and vertical designs. Curved architectural designs continue to emerge and develop, and truss structures also appear in curved forms. The upper and lower chords of the hyperbolic truss are spatial curves, and the manufacture and assembly of components are difficult. After the prefabricated components are transported to the assembly site, steel supports are usually set under the chords to prevent component deformation and facilitate assembly operations. However, the existing steel supports are relatively fixed in size and cannot flexibly adjust the width and height to adapt to hyperbolic trusses of different sizes, which increases the difficulty of assembling hyperbolic trusses.

[0004] In addition, during the truss assembly process, the trusses to be assembled cannot be fixed, making it difficult to meet the specific angles required when splicing different sections of curved trusses, which can easily increase engineering errors. In addition, the existing steel supports are integrated structures, which are not convenient for transportation between different work scenes, and the support height cannot be changed after it is determined, making it difficult to reuse. This means that each truss assembly often requires a new support platform, which makes the assembly operation more cumbersome and the assembly efficiency relatively low. Utility Model Content

[0022] The present invention will be further explained below in conjunction with specific embodiments. The embodiments are implemented based on the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0023] like Figure 1-5 As shown, the utility model is a steel support hyperbolic truss assembly platform with adjustable size, including a prefabricated square steel pipe column 1, an I-shaped steel beam 2, a vertical connecting plate 3, a box beam 4, a clamping device 5 and a telescopic device 6.

[0024] like Figure 1 and Figure 4 As shown, the number of prefabricated square steel pipe columns 1 is two, and a bolt sliding track 12 is provided on the inner side of the prefabricated square steel pipe column 1, and a plurality of fixing bolt holes 11 are provided on the bolt sliding track 12; the fixing bolt holes 11 are arranged at equal intervals along the vertical downward inclination, and grooves are formed to allow semi-threaded bolts to be fixed; a plurality of triangular support plates 13 are provided at the bottom end of the prefabricated square steel pipe column 1, which can enhance the stability of the device and prevent the platform from possibly overturning.

[0025] In this embodiment, there are multiple bolt sliding tracks 12 , and two rows of bolt sliding tracks 12 are provided on a single prefabricated square steel pipe column 1 .

[0026] like Figure 1 , 3 As shown in Figure 4, an I-shaped steel beam 2 is provided between the two prefabricated square steel pipe columns 1. The number of the I-shaped steel beams 2 is two, and the two I-shaped steel beams 2 are symmetrically nested in the box beam 4. The I-shaped steel beam 2 is detachably connected to the prefabricated square steel pipe column 1 through a vertical connecting plate 3. A plurality of first holes 21 are provided on the I-shaped steel beam 2, and the vertical connecting plate 3 is L-shaped. A plurality of second holes 34 are provided on the vertical connecting plate 3. The second holes 34 are aligned in height with the position of the fixing bolt hole 11, and the first bolt 31 passes through the fixing bolt hole 11 and the second hole 34 to connect the vertical connecting plate 3 with the prefabricated square steel pipe column 1; the first hole 21 is aligned in height with the second hole 34, and the second bolt 32 passes through the first hole 21 and the second hole 34 to connect the vertical connecting plate 3 with the I-shaped steel beam 2.

[0027] In this embodiment, the first bolt 31 is a semi-threaded bolt, and the second bolt 32 is a friction-type high-strength bolt; the semi-threaded bolt has a smooth root and a threaded end, and the nut 33 for fixing the two bolts is a common nut 33.

[0028] like Figure 3 As shown, a telescopic device 6 is provided on the I-shaped steel beam 2, and the telescopic device 6 includes a hub motor pulley 61, a first slide rail 62 and a second slide rail 63; the hub motor pulley 61 itself contains power, transmission and braking devices, and its double hubs are embedded between the first slide rail 62 and the second slide rail 63, and can move along the slide rails through the rotation of the hub motor pulley 61; the first slide rail 62 is arranged on the side wall of the I-shaped steel beam 2, and the second slide rail 63 is arranged on the inner wall of the box beam 4. The slide rails are pre-welded and connected to the I-shaped steel beam 2 and the box beam 4 during production, and a part of the length of the I-shaped steel beam 2 is pre-inserted into the box beam 4.

[0029] Fixed limiters are provided on the first slide rail 62 and the second slide rail 63 to prevent the hub motor pulley 61 from exceeding the track length when moving, and to prevent the connection between the I-shaped steel beam 2 and the box beam 4 from failing.

[0030] Start the hub motor pulley 61, and the hub motor pulleys 61 on the two I-shaped steel beams 2 rotate in opposite directions. By moving the hub motor pulleys 61 on both sides in different directions, the pre-inserted length of the I-shaped steel beam 2 can be pulled out, which can expand the distance between the prefabricated square steel pipe columns 1. Similarly, the two hub motor pulleys 61 rotate towards each other to increase the inserted length of the I-shaped steel beam, thereby shortening the distance between the prefabricated square steel pipe columns 1.

[0031] In this embodiment, there are multiple wheel hub motor pulleys.

[0032] like Figure 1 and 2As shown, at least one pair of clamping devices 5 with adjustable height and adjustable spacing is provided on the prefabricated square steel pipe column 1, the clamping device 5 is located above the I-shaped steel beam 2, and the clamping device 5 includes a hydraulic telescopic rod 51, a clamping gasket 52 and a telescopic base 53; the upper part of the telescopic base 53 is a sleeve with an outer square and an inner circle, one end of the telescopic base 53 is fixedly connected to a fixing plate 54, and the other end is connected to the fixed end of the hydraulic telescopic rod 51, the clamping gasket 52 is fixedly connected to the movable end of the hydraulic telescopic rod 51, and a plurality of through holes are provided on the fixing plate 54, and the through holes are aligned with the position height of the fixing bolt hole position 11, and the first bolt 31 passes through the fixing bolt hole position 11 and the through hole on the fixing plate 54 to connect the fixing plate 54 to the prefabricated square steel pipe column 1. This connection method can realize the adjustment of different heights of the clamping device 5 to cooperate with the I-shaped steel beam 2.

[0033] The clamping pad 52 is pushed onto the upper and lower chord surfaces of the pre-assembled truss by using the hydraulic telescopic rod 51, and the truss can be adjusted to a suitable angle and then the hydraulic telescopic rod 51 is activated to fix the truss with the clamping pad 52. Compared with a general assembly platform, the clamping device 5 can more securely fix the truss to be assembled, and can fix the truss at different angles as needed to facilitate accurate assembly.

[0034] In this embodiment, the number of clamping devices 5 is two, and a plurality of vertical connecting plates 3 of different heights may also be provided. The vertical connecting plates 3 are connected to the prefabricated square steel pipe columns 1 by semi-threaded bolts passing through grooves of different heights. Therefore, the beams of different products may be located at different heights, which is more suitable for the assembly of curved trusses.

[0035] The working principle or use process of the utility model is as follows:

[0036] Step 1: According to the size of the upper and lower chords of the truss to be assembled, the relative positions of the I-shaped steel beam 2 and the box beam 4 are adjusted by using the hub motor pulley 61 and the first slide rail 62 and the second slide rail 63, and the hub motor pulley 61 is started. The hub motor pulleys 61 on the two I-shaped steel beams 2 rotate in opposite directions. The hub motor pulleys 61 on both sides move in different directions, and the pre-inserted length of the I-shaped steel beam 2 can be pulled out, which can expand the distance between the prefabricated square steel pipe columns 1. Similarly, the two hub motor pulleys 61 rotate in opposite directions to increase the inserted length of the I-shaped steel beam, thereby reducing the distance between the prefabricated square steel pipe columns 1. The size of the longitudinal I-shaped steel beam 2 is controlled to be larger than the spacing between the upper and lower chords of the truss. After the adjustment is completed, the hub motor pulley 61 at the longitudinal I-shaped steel beam 2 is changed to a braking state.

[0037] Step 2: According to the assembly height requirements of the hyperbolic truss, tighten the semi-threaded bolts at the connection between the vertical connecting plate 3 and the prefabricated square steel pipe column 1 to half loose, so that the smooth root area and the bolt sliding track 12 can move relative to each other without causing the bolts to completely fall off and cause accidents. On this basis, the longitudinal I-shaped steel beam 2 can be lifted obliquely upward along the bolt sliding track 12, and when it is moved to the required height for assembling the hyperbolic truss, force is applied to the concave side of the track, and the bolts are tightened when they enter the steel pipe column fixing bolt hole 11, so that the steel beam is moved to a specific height.

[0038] Step 3: According to the height to which the I-shaped steel beam 2 is moved in step 2, the clamping device 5 is moved to the upper level height of the I-shaped steel beam 2 using the same operation method, and the hydraulic telescopic rod 51 is controlled to be in the initial state.

[0039] Step 4: The hyperbolic truss to be spliced ​​is hoisted in from above the assembly platform, and after being overlapped on top of the longitudinal I-shaped steel beam 2 and adjusted to the splicing angle, the hydraulic telescopic rod 51 is started to make the clamping gasket 52 press against the upper and lower chords of the truss, and the hyperbolic truss is fixed to present an angle suitable for splicing.

[0040] Step 5: After the truss is spliced, it can be pushed forward directly to fall on the vertical connecting plates 3 of different heights that are pre-set and connected to the prefabricated square steel pipe columns 1 through semi-threaded bolts passing through grooves of different heights. Repeat steps 2-4 until the assembly of the entire hyperbolic truss is completed. It is more conducive to the assembly of curved trusses if the beams are not located at the same height. The trusses are spliced ​​in sections. First, according to the curvature of the curved trusses, multiple components are made and adjusted to the height suitable for the curved trusses. They are arranged vertically. After each section of the truss is spliced, it is pushed forward to fall on the front part of the product, and then the next section of the truss can be spliced ​​in a fixed position until the entire truss is spliced.

[0041] The utility model discloses an adjustable-size steel-supported hyperbolic truss assembly platform, which can meet the assembly requirements of trusses of various sizes and angles, especially hyperbolic trusses, by utilizing the whole set of devices, and has a wide range of applications. It can effectively prevent deformation of components and facilitate operation by changing aerial operations to ground operations. While ensuring the quality of assembly and welding, it also reduces the requirements for safety measures in the construction process. Moreover, due to its relatively simple structure and the use of bolt connections, it is convenient and quick to disassemble and assemble, can be reused in different positions, and is more environmentally friendly.

[0042] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
