Person, as shown in figure 4, the assembled unit includes four web members and a bolt sphere；The web member is connected in the bolt sphere,
Form corner wimble structure.Or, as shown in figure 5, the assembled unit includes two top booms, a web member and a bolt
Ball；The top boom and web member are connected in the bolt sphere.
In order to further illustrate steel structure net rack high altitude bulk construction method of the present invention, had below by taking certain engineering as an example
Body explanation.As shown in figure 1, the schematic flow sheet of the engineering construction.
First, preparation of construction
Civil engineering unit application level instrument the relative elevation of rack embedded board on civil engineering bearing-surface is all measured be indicated in it is flat
At the corresponding position of face drawing, and this datagram is supplied to project supervision and rack installation engineer, as installation and to each
The foundation that supporting-point repetition measurement is checked and accepted.
2nd, construction march into the arena material division
Rack is using the assembled formation standard of scaffold coordinative construction platform across then to one side assembled unit Assembly in pieces at height
Install, installed from one side to another side, standard across be installed as this installation emphasis.Rack in a pre-installation parts,
Such as rod member, bolt sphere, taxonomic revision is carried out, by specification size, numbering species marshalling in order, is easy in installation process
Lookup is used.Then needing rod member to be mounted, bolt sphere to arrange out by the sequencing of installation, everything preparation
The installation on ground of rack is can be carried out after carrying out.The classification of front bolt ball is installed to put.
2nd, rod member for grid gets well into assembled unit according to erection sequence in installation on ground, is put by construction location.
3rd, the assembly of starting rack
The 1st, lower edge plane grid is installed, by first across bearing install in place, install first across lower bolt sphere, a lower edge
Bar, constitutes fore-and-aft plane grid, as shown in Figure 6A；Sequence interim fulcrum, it is ensured that lower bolt sphere is in same level；Install first
Web member and upper bolt sphere between unit, usually first cone is the junior unit of the web member of a ball four, rear in place to be twisted with lower bolt sphere
Enter, fix, as shown in Figure 6B；It is the pyrometric cone for first filling the web member of one chord member of a ball two to have bored for second, as shown in Figure 6 C, is then filled out
Enter other two web members, as shown in Figure 6 D, the progressively rack of the complete first module of cycle installation, as illustrated in fig. 6e.
The 2nd, the inverted triangle grid that winds up is installed；Rack second unit is risen using side after installing assembling, as fig 6 f illustrates, from end bay
Start to install a ball one first to wind up the pyrometric cones 7 of two web members, then a ball two is installed and is winded up the quadrangular pyramids 8 of two web members, by two
Diagonal web member is supported in lower bolt sphere, up tenses top boom, is made top boom progressively close to mounted upper bolt sphere, is twisted
Enter.
4th, the high altitude bulk of follow-up rack
Assembly in pieces at height is by the component of rack（Base parts and components or assembled unit）Design attitude is hung to directly to be spelled
The method of dress.When aiding in high assembling method using suspender, the amount of deflection of rack installation process should be controlled, increase otherwise should be taken to support
Measure, need to be set up on ground scaffold or steel column support install.
1st, base parts and components are spliced into assembled unit；
Rack is reasonably divided into various assembled units according to actual conditions：For example, directly by single rod member, single section
Point, the bar of a ball one, the bar of two ball one are always combined into rack.Such as, by assembled unit, the bar of a ball four（Corner cone）, a ball three
Bar（Triangular pyramids）Always it is combined into rack；In another example, intermediate combination unit is constituted by assembled unit and is always combined into rack again.
2nd, temporary support point is set：Temporary support point arrangement is carried out by rack erection sequence, and supporting-point arrangement should be uniform.Should
The total settlement caused by factor such as joint distortion, elastic compression, foundation settlement of support will be supported to control in below 5mm, supporting-point
Place can set the jack of adjustment absolute altitude between rack lower edge and support.
3rd, grid structure with bolt-sphere joints is always spelled：
Bolt-ball net frame first across start assembly when, be usually first spell lower edge, by the absolute altitude of lower edge, axis trimming it is good after,
Bolt all is tightened, is played the role of positioning.
Then it is attached web member and winds up.It is general in construction to use the combination list that quadrangular pyramid is combined into web member that winds up
Member, is combined the installation of unit.The bolt of each assembled unit should be tightened simultaneously, and indivedual bolt quilts should be prevented during construction
Jam-packed, causes bolt to be effectively installed in place.
Later lower edge and another side web member can be installed using single-piece, it would however also be possible to employ the method for installing quadrangular pyramid is entered
Row is installed.Circulation carries out the installation of above-mentioned steps, completes the installation of whole rack.Rack is installed general using a grid as one
Row, promotes by row.
4th, net rack support dropping place：
Net rack support dropping place refer to rack it is assembled after the completion of supporting-point on striking, make rack by temporary support state
Operating process of the smooth transition to the permanent bearing of design.Rack dropping place should follow following principle：Pass through during the dismounting of temporary support
The jack being placed on bearing repeatedly circulates micro decline to realize that load equilibrium is shifted.Need to check under jack before dropping place
Whether drop stroke meets the requirement of the deflection value, to consider because rack sinking causes stroke to increase when calculating jack stroke
Value, enough stroke surplus is reserved accordingly.
5th, the inspection and measurement of rack and subsequent treatment
After whole rack installation comprehensively, it is necessary to checked, check whether bolt is tightened, now jackscrew should be in height
The position of strength bolt keyway deep trouth.Whether correct the parts such as all rod members, ball install, and whether there is deformation.Rack longitudinal direction, horizontal stroke should be measured
The amount of deflection conducted oneself with dignity to length, bearing absolute altitude and off-centring, rack.
The tolerance that steel grid structure is installed（mm）
The subsequent treatment of rack
Rack carries out benefit brush to the bolt sphere that is touched off in work progress, sleeve paint after installing, unnecessary cavity and
Gap is blocked with oil loam.
Each technical characteristic of above-mentioned disclosure is not limited to disclosed and further feature combination, and those skilled in the art are also
Other combinations between each technical characteristic can be carried out according to the purpose of invention, are defined by the purpose for realizing the present invention.
