Abstract
The utility model provides an adjustable support for the installation of a steel structure. Since the adjustable support can be adjusted upwards and downwards and a positioning support steel plate is arranged at the top part and is welded at the top part of a support bar, after the support vertical bar of the adjustable support is installed, the adjustable support can do plane rotation around the steel pipe of the support vertical bar, the fine tuning of coordinate points can be realized through a total station to ensure accurate positioning, the requirements on the three-dimensional spatial coordinates of steel latticed shell nodes can be satisfied finally and the alignment to the three-dimensional coordinate points at the bottom of the steel latticed shell nodes and the positioning of the steel latticed shell nodes are convenient. Moreover, since a steel latticed shell node plate is temporarily fixed on the positioning supporting steel plate of the adjustable support through spot welding, not only the positioning of the steel latticed shell nodes is ensured to be accurate and firm but also the positioning, the connection, the installation and the welding of latticed shell bar pieces can be conducted immediately to form an integral latticed shell.

Further, the Steel Structure Installation of the above is with in the adjustable supports device: described steel vertical rod is a steel pipe by the fixing hollow of the horizontal steel tube of a fastener and a moulding bed.Also comprise hound in addition, described hound is a reinforcing bar, and an end points is welded on described " U " type rest, and an end points is welded on the described moulding bed.
A kind of Steel Structure Installation of the present utility model with the adjustable supports device owing to can adjust up and down, and be provided with the top that a location rest steel plate is welded on support bar at the top, after the bearing vertical rod of this adjustable supports device has installed, can do the plane around the bearing pole steel tube rotates, and coordinate point is finely tuned according to total powerstation, make its accurate location, finally meet the three dimensional space coordinate requirement of steel screen node, and be convenient to aim at the three-dimensional coordinate point at the bottom of the steel screen node and locate.
That this method has is with low cost, it is simple, easy to operate to make, superiority that work efficiency improves, construction quality guarantees.
Below in conjunction with the drawings and specific embodiments the utility model is done comparatively detailed description.
Description of drawings:
Accompanying drawing 1 is a kind of adjustable supports device structural representation of the utility model embodiment 1.
Accompanying drawing 2 supports two cruciform gusset plate welding rod schematic representations for the adjustable supports device that uses two embodiment 1.
Among the figure: 1, moulding bed, 2, support bar, 3, location rest steel plate, 4, vertical rod, 5, " U " type rest, 6, nut, 7, handle, 8, hound, 9, fastener, 10, allocation control points, 11, rod member, 12, cruciform gusset plate.
The specific embodiment
As shown in Figure 1, a kind of Steel Structure Installation adjustable supports device, put on net shell anchor point, the support node plate, comprise steel support bar 2, location rest steel plate 3, a steel vertical rod 4, steel vertical rod 4 is a steel pipe by the fixing hollow of other steel pipe of a fastener 9 and a moulding bed 1, described steel support bar 2 is a screw rod, described location rest steel plate 3 is one vertically to be welded on the square plate on the described support bar 2, on described vertical rod 4 tops one with handles 7 nut 6 is set, screw thread on the described support bar 2 and 6 engagements of described nut extend in the middle of the described vertical rod 4.In order to guarantee when the swivel nut 6, support bar moves vertically, nut 6 is provided with the button with axial limiting in described steel vertical rod 4, is provided with " U " type rest 5 on described support bar 2 tops, the described location of welding rest steel plate 3 in described " U " type rest 5.In addition, also comprise hound 8, described hound 8 is a reinforcing bar, and an end points is welded on described " U " type rest 5, and an end points is welded on the described moulding bed 1.Behind the preliminary installation in position of adjustable supports device of present embodiment, can pass through handle 7 swivel nuts 6, like this, just can make the support bar 2 that is positioned at it flexible up and down,, reach the requirement of net shell node absolute altitude to regulate the height of location rest steel plate 3, simultaneously, can promote slightly and rotate support bar 2, drive location rest steel plate 5 rotation above it, under the observing and controlling of total powerstation, reach the accurate positioning requirements of space coordinates of net shell node.
The adjustable supports device of present embodiment is owing to can adjust up and down, and be provided with the top that a location rest steel plate is welded on support bar at the top, after the bearing vertical rod of this adjustable supports device has installed, can do the plane around the bearing pole steel tube rotates, and coordinate point is finely tuned according to total powerstation, make its accurate location, finally meet the three dimensional space coordinate requirement of steel screen node, and be convenient to aim at the three-dimensional coordinate point at the bottom of the steel screen node and locate.Simultaneously, use spot welding in this method, temporarily anchor on the location rest steel plate of adjustable supports device, both guaranteed the steel screen node locating accurately, firmly, can carry out net shell rod member location, connection again immediately and welding is installed, formation net shell integral body the steel screen gusset plate.
