Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment the present invention is further detailed explanation.
The installation method of the present invention overarm steel construction stress system is mainly used in the reinforcing and improvement project of building.
The installation method of the present invention overarm steel construction stress system, as depicted in figs. 1 and 2, need to transform building first
Support steel beam 2, and the water between the top of supported on both sides girder steel 2 are fixed by 18 level of crab-bolt respectively in the top of 1 both sides of structure
Flat fixation is welded to connect channel-section steel 3, and 3 vertical support girder steel 2 of channel-section steel.With reference to Fig. 3, after the completion of channel-section steel 3 is welded and fixed, in channel-section steel 3
Install and hang drawing girder steel 4 in bottom.When drawing girder steel 4 is hung in installation, the mode for first passing through surveying setting-out draws girder steel 4 fixed to hanging on channel-section steel 3
Position, and the position for hanging drawing girder steel 4 is marked, then a cloth bag 5 is set in and is hung outside drawing girder steel 4, and two are adopted by truck crane 6
Cloth bag 5 is lifted to hang drawing marked locations of the girder steel 4 on channel-section steel 3 by the mode of point lifting, will hang drawing steel afterwards in cloth bag 5
Beam 4 is fixedly welded on channel-section steel 3 hangs oneself and draws the marked locations of girder steel 4, wherein the bottom for hanging the top and the channel-section 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, after hanging drawing 4 installation of girder steel, truck crane 6 is still in working condition, and passes through the automobile
Hanging 6 carries out an installation for overarm 7.Control line is released in the bottom for hanging drawing girder steel 4 first, and (this is this area routine techniquess, in figure
It is not shown), the control line is equal to a diameter for overarm 7 for spacing between two-wire, and the bilinear con- trol line；Then hanging drawing steel
Bottle gouard moved by hands 8 is installed in the bottom of beam 4, lifts by crane interior card overarm 70 by truck crane 6, afterwards by interior card overarm 70 with it is manual
Calabash 8 connects, and manually calabash 8 lifts interior card overarm 70, and carries out position adjustments to an overarm 70, until interior card hangs
The bending place of beam 70 with hang the bottom of drawing girder steel 4 against and ensureing interior card overarm 70 in bilinear con- trol line, now, automobile
Hang 6 and bottle gouard moved by hands 8 be in tension.Then both sides overarm 71 is worn from the reserved opening of support steel beam 2 respectively
Cross, and the one end of the both sides overarm 71 is connected with the both ends of interior card overarm 70 by branch sleeve 9 respectively, here
Adjusted in connection procedure mutually, final connection ensures the bending place and the bottom pair for hanging drawing girder steel 4 of interior card overarm 70 when completing
Standard, the bending place of both sides overarm 71 are aligned with the reserved opening of support steel beam 2.After the completion of position adjustments, drawing girder steel 4 will be hung
The bending place of bottom and interior card overarm 70 be welded and fixed, and drawing girder steel 4 near hanging for the place of the being welded and fixed both sides
Between be welded and fixed stiffener 10 between an overarm 70, strengthen an overarm 7 and 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
Put, both sides overarm 71 is through the reserved opening on 2 web of support steel beam, and ensures the bending place of both sides overarm 71 and support
The reserved opening alignment of girder steel 2, i.e., be aligned with the web of support steel beam 2.Then at the reserved opening support steel beam 2 web two
Side is respectively provided with stiffener 11, and the stiffener 11 is respectively welded fixation with the web both sides of support steel beam 2, now both sides overarm
71 pass through the stiffener 11, and the space between both sides overarm 71 and stiffener 11 is filled up by weld seam.The stiffener 11
Effectively strengthen the connection reliability of an overarm 7 and support steel beam 2.
After the completion of opening 7 lifting of overarm, as shown in fig. 7, carrying out the installation of suspension rod 12.Hang and draw the bottom of girder steel 4 to fix welding
There are two to hang 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 respectively, and this hangs
Screw thread, suspension rod 12 also be provided with screw thread on the outside of the one end that cylinder 13 of helping pull a cart is connected with hanging, the screw thread on the outside of the suspension rod 12 with hang drawing
The stricture of vagina of 13 inside spiral shell of sleeve is engaged.12 one end of suspension rod penetrates to hang helps pull a cart in cylinder 13, and hang with this cylinder 13 of helping pull a cart tighten it is solid
It is fixed, the installation of suspension rod 12 is completed, the lifting of steelframe 14 is then carried out.Four suspension centres are welded first on four angles of steelframe 14,
Manually hoist draws four suspension centres of steelframe 14, and adjusts steelframe 14, makes steelframe 14 be located at its setting position, by suspension rod 12
Fix through steelframe 14 and with nut screwing clamping, complete the lifting of steelframe 14.Then steel pipe inclined ladder 16 is set up, by the steel pipe inclined ladder
16 top surfaces that steel plate 17 is transported to steelframe 14, and the installation of steel plate 17 is carried out, thus complete entirely to open overarm steel construction stress
The installation of system.Fig. 8 is the plane graph of the present invention overarm steel construction stress system installation.
In the installation method of the present invention overarm steel construction stress system, both sides 71 ends of overarm are provided with external screw thread, in
Between the both ends of an 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 engaged with 9 female 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 adjust in this tightens fixation procedure, it is ensured that when tightening fixation and completing, the bending place of interior card overarm 70 with hang
The bending place of the bottom alignment of girder steel 4, both sides overarm 71 is drawn to be aligned with the reserved opening of support steel beam 2, in realizing
Between an overarm 70 and both sides hang oneself from a beam and 71 be fixedly connected.
The installation method of the present invention overarm steel construction stress system, simple operation, and an overarm makes whole steel construction more
Plus sturdy and durable, the use time built after extending transformation；It is during basic solution building renovation, original as building need to be transformed
Structure is to lifting machine using the problem for impacting.
