Specific implementation mode
Below in conjunction with the accompanying drawings and specific implementation mode the present invention is described in further detail.
The installation method that the present invention opens overarm steel construction stress system is mainly used in the reinforcing and improvement project of building.
The present invention opens the installation method of overarm steel construction stress system, as depicted in figs. 1 and 2, building need to be transformed first
Support steel beam 2, and the water between the top of girder steel 2 supported on both sides are fixed in the top of 1 both sides of structure by the way that anchor bolt 18 is horizontal respectively
Flat fixation is welded to connect channel steel 3, and 3 vertical support girder steel 2 of channel steel.In conjunction with Fig. 3, after the completion of channel steel 3 is welded and fixed, in channel steel 3
Bottom installation, which is hung, draws girder steel 4.When drawing girder steel 4 is hung in installation, the mode for first passing through surveying setting-out draws girder steel 4 fixed on channel steel 3 to hanging
Position, and the position hung and draw girder steel 4 is marked, then a cloth bag 5 is set in hang and is drawn outside girder steel 4, and two are used by truck crane 6
Cloth bag 5 is lifted to the marked locations hung and draw girder steel 4 on channel steel 3 by the mode of point lifting, will hang drawing steel in cloth bag 5 later
Beam 4, which is fixedly welded on channel steel 3, hangs oneself and draws the marked locations of girder steel 4, wherein the bottom for hanging the top and the channel steel 3 that draw girder steel 4 is solid
Surely it is welded to connect, thus completes to hang the installation for drawing girder steel 4.
As shown in Figures 4 to 6, it hangs and draws girder steel 4 after installation is complete, truck crane 6 passes through the automobile still in working condition
It hangs 6 and carries out an installation for overarm 7.Releasing control line in the bottom for hanging drawing girder steel 4 first, (this is this field routine techniques, in figure
It is not shown), which is two-wire, and spacing is equal to a diameter for overarm 7 between the bilinear con- trol line；Then drawing steel is being hung
Bottle gouard moved by hands 8 is installed in the bottom of beam 4, by truck crane 6 by 70 lifting of interior card overarm, later by interior card overarm 70 and manually
Cucurbit 8 connects, and interior card overarm 70 is promoted by bottle gouard moved by hands 8, and carry out position adjusting to an overarm 70, until interior card is outstanding
The bending place of beam 70 and hanging draw the bottom of girder steel 4 against and ensureing interior card overarm 70 in bilinear con- trol line, at this point, automobile
Hang 6 and bottle gouard moved by hands 8 be in tension.Then both sides overarm 71 is worn out of support steel beam 2 reserved opening respectively
It crosses, and the one end of the both sides overarm 71 is connect by branch sleeve 9 with the both ends of interior card overarm 70 respectively, herein
It is adjusted mutually in connection procedure, final connection ensures the bending place of interior card overarm 70 and hangs the bottom pair for drawing girder steel 4 when completing
Quasi- is aligned at the bending place of both sides overarm 71 and the reserved opening of support steel beam 2.After the completion of position is adjusted, it will hang and draw girder steel 4
Bottom and interior card overarm 70 bending place be welded and fixed, and close to the place of the being welded and fixed both sides hanging draw girder steel 4 and in
Between be welded and fixed stiffener 10 between overarm 70, enhancing overarm 7 with hang the connection reliability for drawing girder steel 4.
In a preferred embodiment, support steel beam 2 is I-steel, and the reserved opening of support steel beam 2 is set on its web
It sets, both sides overarm 71 passes through the reserved opening on 2 web of support steel beam, and ensures bending place and the support of both sides overarm 71
The reserved opening of girder steel 2 is aligned, i.e., is aligned with the web of support steel beam 2.Then at reserved opening support steel beam 2 web two
Stiffener 11 is respectively set in side, and fixation is respectively welded in the web both sides of the stiffener 11 and support steel beam 2, at this time both sides overarm
71 pass through the stiffener 11, and the gap between both sides overarm 71 and stiffener 11 is filled up by weld seam.The stiffener 11
The effectively connection reliability of enhancing overarm 7 and support steel beam 2.
After the completion of opening 7 lifting of overarm, as shown in Figure 7 to 9, the installation of sunpender 12 is carried out.It hangs and the bottom of girder steel 4 is drawn to fix
It is welded with two and hangs cylinder 13 of helping pull a cart, this hangs the both sides that cylinder 13 of helping pull a cart is located at interior card overarm 70, this hangs inside cylinder 13 of helping pull a cart
Equipped with screw thread, sunpender 12 also is provided with screw thread with hanging on the outside of the one end that cylinder 13 is connect of helping pull a cart, the screw thread in 12 outside of sunpender with
The line for hanging 13 inside spiral shell of cylinder of helping pull a cart matches.12 one end of sunpender, which penetrates, to be hung and helps pull a cart cylinder 13, and is hung cylinder 13 of helping pull a cart with this and twisted
It fastens, completes the installation of sunpender 12, then carry out the lifting of steelframe 14.Welding four is hung first on four angles of steelframe 14
Point is hung four suspension centres for drawing steelframe 14 by bottle gouard moved by hands, and adjusts steelframe 14, so that steelframe 14 is located at its setting position, will be hung
Bar 12 passes through steelframe 14 and tightens fixation with nut, completes the lifting of steelframe 14.Then steel pipe inclined ladder 16 is set up, the steel pipe is passed through
Steel plate 17 is transported to the top surface of steelframe 14 by inclined ladder 16, and carries out the installation of steel plate 17, thus completes entirely overarm steel construction
The installation of stress system.Figure 10 is the invention overarm steel construction stress system installation method top plan view that installation is complete signal
Figure.
The present invention opens in the installation method of overarm steel construction stress system, and both sides 71 ends of overarm are equipped with external screw thread, in
Between the both ends of overarm 70 also be provided with external screw thread, the both sides 71 end external screw threads of overarm and interior card are hung oneself from a beam 70 both ends
External screw thread is matched with 9 internal thread of branch sleeve, and the both sides overarm 71 and interior card overarm 70 are tightened with branch sleeve 9 respectively
It is fixed, and mutually adjusted in this tightens fixation procedure, guarantee tighten it is fixed when completing, the bending place of interior card overarm 70 with hang
The bottom alignment of girder steel 4 is drawn, is aligned at the bending place of both sides overarm 71 and the reserved opening of support steel beam 2, in realizing
Between overarm 70 and both sides hang oneself from a beam and 71 be fixedly connected.
The present invention opens the installation method of overarm steel construction stress system, simple operation, and an overarm makes entire steel construction more
Add sturdy and durable, to be built after extension transformation usage time；It is original since building need to be transformed during basic solution building renovation
The problem of structure impacts lifting machine use.
