DETAILED DESCRIPTION OF THE INVENTION [0001] BACKGROUND OF THE INVENTION The present invention relates to an out-cable
It relates to the construction method of the steel roof used. [0002] [Prior Art] Lateral drawing is one of the construction methods for large steel roofs
The law is being enforced. According to this method, as shown in FIG.
A temporary gantry a is provided at the end of the building, and is mounted on the temporary gantry a.
One block of truss beam c on jack b
Complete the assembly, jack down, and each Trusby
Jack down and side pulling with a sub beam (main building) d
Connected with sub beam d of the preceding truss that ended, out
Attach cable f and tighten, roofing material g, other clay
It is a construction method that attaches ancillary equipment such as
You. [0003] SUMMARY OF THE INVENTION
In the horizontal drawing method, the truss-vibration method shown in FIG.
Jack down process, out cable shown in (b)
Installation, tensioning process, roof finishing and crane shown in (c)
Deformation of each beam is different in the attachment process of auxiliary equipment such as
You. [0004] For this reason, a sub-unit for connecting truss blocks to each other
A level difference occurs in the beam (main building),
A great deal of work was required for the joining work. Also as shown in FIG.
If there is a crane rail in
The final deflection (δFive+ Δ6= Δ7) Occurs, Where δFive: (Deflection due to the weight of steel frame)-(Autoke
Rise of beam due to cable tension) = δ8−δ9 δ6: Deflection by roof finish and crane rail δ7: Final deflection = δFive+ Δ6 δ8: Deflection caused by steel weight due to jack down δ9: Rise up of beam due to tension of out cable The method of adjusting the level by attaching the crane rail is taken.
Crane rail installation work was not possible on the gantry. The present invention has been made in view of the above-mentioned problems of the prior art.
The purpose of the project was to improve the workability.
Use of cable-stayed beams that have been improved and construction efficiency has been improved
The point is to provide a construction method for steel roofs. [0006] In order to achieve the above object,
First, a steel frame shop using the out-cable beam stringer according to the present invention
According to the construction method of the root, on the gantry where the jack was installed
Truss beams and columns that form part of the steel roof
The truss beams are used as the steel's own weight, roof finishing material, and auxiliary equipment.
Beam rise due to out-cable tension from bending
Jack down by the final deflection amount
A truss beam is placed on the gantry from above
The support rail on the support frame that extends perpendicular to the truss beams on the side
To the truss beam,
Attach root finishing materials and ancillary equipment, and out cable.
At the same time, the next place on the gantry
Assemble truss beams and columns, tie truss beams ahead of this
The truss beam assembled and joined is laterally pulled,
Hereinafter, the above steps are repeated. [0007] According to the present invention, a jack is provided as described above.
The upper and lower strings that form part of the steel roof on the gantry
Composed of parallel string truss made of wood and lattice
Assemble the lath beam and column, and use the same truss beam as the final deflection
Jack down and slide the truss beam on the gantry.
Remove the jack by supporting it through the timber, inside the gantry
Support that extends inward in a direction orthogonal to the truss beam
Use the sliding material on the rails on the frame
Replacing the truss beam supported by, and pulling it sideways. [0008] Thus, the toe pulled laterally inward of the gantry
Attach roofing materials, crane rails and equipment to lath beams
And attach the out cable and tighten. Along with this
To assemble the next truss beam and column on the gantry,
Truss beam, and the
Join the lath beam and pull both truss beams in the same way as above
Then, the above steps are sequentially repeated to construct the steel roof.
Now. [0009] The truss beam is previously mounted on a gantry as described above.
Jack down by the final deflection amount.
Set the support rails according to the deflection) Finish the roof
Installation of materials and auxiliary equipment Out cable installation and tensioning
As a result, a deformation difference occurs between the truss beams in each process.
The roof can be laid horizontally at the same level without truing
It will be. [0010] BRIEF DESCRIPTION OF THE DRAWINGS FIG.
You. Wife end of steel roof constructed by the method of the present invention
A gantry 2 with a support jack 1 for assembly along the part
Is installed, and a support jack 1 for assembly in each gantry 2 is provided.
The upper and lower strings 3a, 3b and lattice members 3c
The lath beam 3 is assembled. (See FIGS. 1 and 5) The truss beam 3 has a final deflection δFourJust jack down
It is. Where δFour= Δ 1+ ΔTwo−δThree1: Self weight of steel frame
Deflection, δTwo: Deflection due to roof finishing load, etc., δ
Three: Rise up of beam due to tension of out cable)
The truss beam 3 jacked down as shown
Between the truss beam 3 and the support frame 4
On the support rail 5 bridged so as to extend inward
And is supported via a sliding member 6 (see FIGS. 2 and 6).
Replacement on the support rail 5 via the same sliding member 6
At the same time, the next truck is placed on the gantry 2.
The beam 3 'is assembled. (See FIGS. 3 and 7) Thus, the truss beam 3 and the next truss beam 3 'are drawn horizontally.
And the truss beam 3
Install lane rail 8 and other equipment and roofing material 9
Attach the out cable 10 and tighten it.
The next truss beam 3 'assembled on the gantry 2 and the
The lath beam 3 is joined to the lath beam 3 via the connecting member 7 and laterally pulled.
(See FIGS. 9, 10, and 11) The above steps are repeated to build a steel roof. [0011] According to the present invention, a steel roof is provided as described above.
Truss beams and columns that make up the gantry with jacks installed
Assembled on top, jacked the truss beam by the final deflection
And slide the truss beam on the support rail on the gantry.
Supported through the timber, inside the gantry perpendicular to the truss beam
Replace with the support rail on the support frame extended in
Kishi, truss beams that have been laterally drawn in this way have a roof finish
Attach additional equipment such as
Attach the outgoing cable and tighten it.
Assemble the lath beam and column, and tie the truss beam of the same rank
Reverse the process of joining the truss beam to be assembled and pulling it sideways.
So that it is flat on the gantry and the support frame.
The construction work of the steel roof was performed, and the work efficiency was remarkable.
Is improved. Further, a truss for steel roof construction on the gantry.
When assembling the beam, the truss beam is made up of steel weight, roof finishing material,
Due to the deflection of the attached cable,
Of the final deflection excluding the rise-up of the beam
Lock down and set the support rail to the final deflection.
Install the roof finish, attached equipment,
At each step, the cable is attached and tensioned.
There is no deformation difference in the lath beam, and the roof is horizontally pulled at the same level
Because it can be built, if the connection of the truss beam connecting material becomes easy
Both before and after the tension of the out cable,
No pre-stressing occurs one beam at a time
Prestress does not disperse in the adjacent beam even if it is introduced. Also
Truss beams jacked down on gantry 2 are already final
At this point, the crane rail
Installation and level adjustment can be done on the gantry, so workability is remarkable
It improves and the accuracy improves.
