Description
Technical field
The present invention relates to Construction of The Grids technical fields, particularly relate to a kind of method for replacing grid node.
Background technology
The light roof of large span, using grid structure, steel using amount can greatly reduce, and save cost, and the Beauty
It sees, is gradually received by owner and design side.But since rack span is big, the rod piece of grid structure is all prefabrication type component,
By amount of deflection and installation cumulative errors etc. are various influences in installation process, it is a lot of to be bound to cause rack installation quality problem.Greatly
Multilist is present:Gap between rod piece sleeve and bolt sphere is more than that code requirement, sleeve are directly welded by cutting during the installation process
It is connected to the first-class problems of bolt sphere.Eample Analysis is carried out with regard to this installation question below.
Xi'an arenas is oval curved surface grid structure, 152 meters of length, 148 meters of width.Grid node is bolt ball-joint
Point and part welded spherical node.There are gap, sleeves to cut between the radial rod piece sleeve of discovery and bolt sphere after installation is completed,
The problems such as without sleeve, influences the security presence of grid structure.Since radial rod piece is the main stressed member of Elements of Space Grid Truss, rod piece
For pull rod or compression bar.Since rack has installed, to rack dismounting reinstall it is costly, and the duration cannot expire
Foot requires.Such as radial rod piece is replaced, it is big that there are difficulty of construction, constructs complicated, big to structure security implication and is not easy to protect
Demonstrate,prove installation progress and construction quality.
Invention content
For the deficiency in above-mentioned background technology, the present invention proposes a kind of method for replacing grid node, solves existing
Difficulty of construction is big when grid node is replaced in technology, to structure security implication, big, construction speed and construction quality can not ensure
Technical problem.
The technical proposal of the invention is realized in this way:A method of grid node is replaced, is included the following steps:
Step 1:Gap between pacch bolt ball and rod piece sleeve;
Step 2:Measure the installation site of steel pipe anchor ear;
Step 3:The rod piece of bolt sphere of polishing both sides;
Step 4:Brushing steel steel binder on rod piece after polishing;
Step 5:Side steel pipe anchor ear is installed on steel steel stick;
Step 6:Contraposition installation other side steel pipe anchor ear;
Step 7:It is installed between the steel pipe anchor ear of both sides high-strength to drawing anchor bolt;
Step 8:It tightens to drawing anchor bolt stress;
Step 9:Replace the bolt sphere between rod piece;
Step 10:Completion acceptance.
When the step 1 carries out gap repairing, filled up first using electric welding, voltage, the electric current of welding, which will meet construction, to be wanted
It asks, grinding process is carried out to welding residue at gap after squeegeeing, residue and smooth is not stayed in guarantee.
It is measured using the tape measure examined when the step 2 measures, carrying out scene with the use of square puts
Sample ensures error within 1mm, and slate pencil underlining on rod piece is used after determining the installation site of steel pipe anchor ear.
When the step 3 carries out rod piece polishing, uses sander to carry out processing of rust removing first, rod piece is polished
Then metallic luster uses wheel polisher to carry out roughness processing to rod piece, rod piece is made to obtain larger roughness, line of polishing
Lu Yingyu steel Impact directions are vertical, are stained with acetone by the rod piece wiped clean after polishing using staple thereafter.
When the step 4 brushing steel steel binder, brushing will uniformly, and thickness is maintained in 0.5mm-1mm.
When the step 5 and step 6 installation steel pipe anchor ear, close inspection installation effect, with hand hammer along stickup after stickup
Face gently taps steel pipe anchor ear, indicates to have pasted if without empty sound closely knit, otherwise should peel steel pipe anchor ear, carry out glue, weight
It is new to paste.
When tightened in the step 8 to drawing anchor bolt, using torque wrench to drawing anchor bolt to fasten, ensureing to drawing anchor
The screw rod of bolt is 2-3 exposed, checks whether bolt loosens using hammering method after fastening.
This law is simple in structure, easily fabricated, easy to use, of low cost, can not only stablize and realize that rod member for grid stress passes
It passs, and can accelerate construction progress, is highly practical, safety guarantee is provided for rack reinforcing.Rod member for grid design is thought of as axle center
Stressed member, i.e. rod member for grid stress are pressure or pulling force, present invention can ensure that grid structure is safe, former rod member for grid
Stress is avoided bolt sphere and is transferred on the rod piece of other side, and the consolidation process to rod member for grid has been reliably achieved, can be convenient
Ground carries out grid node and repairs replacement, solves in the prior art, and grid node replacement difficulty of construction is big, and construction quality is not
Reliable problem.
Specific implementation mode
The technical scheme in the embodiments of the invention will be clearly and completely described below, it is clear that described implementation
Example is only a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, this field is common
The every other embodiment that technical staff is obtained under the premise of not making the creative labor belongs to the model that the present invention protects
It encloses.
A method of grid node is replaced, is included the following steps:
