Description

Technical Field

[0001] The utility model relates to the technical field of space steel trusses, and particularly relates to an adjustable assembly falsework device applicable to space steel trusses. Background Art

[0002] With the innovation and development of different structural forms of steel structures, space steel trusses, as an important form of the development of steel structures, are applied more and more widely, especially in large-scale infrastructure such as airport terminals, convention centers, and stadiums. The traditional construction of space steel trusses is to gradually weld each member of the space steel truss on the top of the column. This construction method has problems such as a large amount of high-altitude welding, low safety of high-altitude construction, a large amount of high-altitude transportation, and low construction efficiency. In view of these problems, the integrated construction application of space steel trusses has received more and more attention. The integrated construction of space steel trusses requires the assembly and welding work of the space steel truss to be completed on the ground first, and then the assembled and welded space steel truss is lifted to the top of the column and welded. Since the space steel truss needs a certain clearance to achieve the height required for its welding on the ground, falsework needs to be arranged under each main truss of the space steel truss to achieve this height, and the height of the falsework should also be able to be freely adjusted according to the height required for welding. In addition, the common steel truss assembly falsework at present has disadvantages such as non-adjustable height and a large amount of welding work during on-site use. Content of the Utility Model

A column top base 3 for placing the steel truss 10 is installed at the top of the cross-lifting device 2.

[0026] In this embodiment, the track box is adjustably installed in the front-back direction of the double-row track ground beam, and the cross-lifting device is adjustably installed in the height direction on the track box, realizing the adjustable distance and height between the two column top bases, so as to meet and adapt to the assembly and welding work of different forms of spatial steel trusses.

[0027] In a specific example, the track box 1 includes a track plate 101, an extension plate 102, a ground beam bolt 103, and an arc-shaped track groove 106. The track box 1 is formed by welding four track plates 101 in pairs around its perimeter. Two arc-shaped track grooves 106 are opened on the middle side of each track plate 101, for a total of eight arc-shaped track grooves 106. Two rows of threaded holes are opened on both sides of each arc-shaped track groove 106, with a certain distance reserved from the upper and lower edges of the track plate 101. The upper edge of the arc-shaped track groove 106 is open, and the lower edge extends to the outside of the lowermost row of bolt holes, with a certain distance from the lower part of the track plate 101. The extension plate 102 is located below the track box 1. Threaded holes are opened at the four corners and the middle positions on both sides of the extension plate 102, and it is connected to the double-row track ground beam 4 through the ground beam bolts 103.

[0028] In a specific example, it further includes a stiffening rib 104. The stiffening rib 104 is welded to the track plate 101 and the extension plate 102. Two stiffening ribs 104 are arranged on each track plate 101, and the two stiffening ribs 104 are respectively arranged at the middle positions between the outer threaded holes and the outer edge of the track plate 104.

[0029] The stiffening ribs in this embodiment can be used to maintain the structural stability of the entire track box.

The track ball 203 can rotate freely on the track ball rotating shaft. The track ball 203 moves in the two arc-shaped track grooves 106 in the middle of the track plate 101. The vertical bearing plate 205 is located below the lifting plate 201, and the side surface of the vertical bearing plate 205 is welded to the surface of the lifting plate 201, symmetrically arranged along both sides of the track ball 203 and the two sides of the lifting plate 201.

The threaded holes on the vertical bearing plate 205 can correspond to the threaded holes on the track plate 201.

[0033] It should be noted that when the upper surface of the vertical bearing plate touches the lower surface of the height control plate, it indicates that the maximum height of the cross lifting device has been reached. The height of the cross lifting device should be slightly reduced and the cross lifting device should be fixed by passing the connecting bolts through the threaded holes of the vertical bearing plate and the track plate.

[0034] In a specific example, it further includes a lifting control device 5.

The thickness of the two trapezoidal track grooves 303 should be about half of the thickness of the column top base plate 301, and a locking bolt hole is opened at each end point; the trapezoidal track groove 303 is used for the movement of the trapezoidal track block 304. There are a total of four trapezoidal track blocks 304, and each trapezoidal track block 304 can slide freely in the placed trapezoidal track groove 303; the trapezoidal track block 304 is welded to the circular retaining column 302.

[0037] It should be noted that when each trapezoidal slider and circular stop post move to the trapezoidal track groove to fix the steel truss, the trapezoidal slider and circular stop post can be fixed on the trapezoidal track groove by passing the locking bolts through the threaded holes reserved on each trapezoidal slider; when a certain trapezoidal slider and circular stop post are in an idle state, the trapezoidal slider and circular stop post can be pulled to the initial position at the corresponding corner edge, and the trapezoidal slider and circular stop post can be fixed on the top plate of the column by passing the locking bolts through the threaded holes reserved on each trapezoidal slider and the top plate of the column.

It has mobility on the ground beam and can install several devices on the ground beam according to needs for the welding work of spatial steel trusses;
