Abstract
The invention discloses a high-altitude bulk construction method for a steel-structure grid. The method comprises the steps as follows: 1), the steel-structure grid is divided into a starting grid and a follow-up grid; 2), a scaffold construction platform is set up at the position of the starting grid, and then construction of the starting grid is carried out by means of the scaffold construction platform; and 3), a constructor carries out the construction of the follow-up grid by considering the starting grid as an operation platform. In the steps above, before construction of the starting grid and the follow-up grid, basic parts such as bolt spheres, chord members and web members are spliced into an assembled unit, and then the assembled unit is hoisted to a construction position, so that splicing construction of the starting grid and the follow-up grid is carried out. According to the method, workload required for setting up a scaffold is reduced; revolving material consumption is low; setting-up time for the scaffold is saved at the same time; and the construction cost is reduced. Besides, the basic parts are spliced into the assembled unit and a high-altitude assembled unit simultaneously, so that the construction progress can be accelerated.

In order to further illustrate steel structure net rack high altitude bulk construction method of the present invention, be specifically described for certain engineering below.As shown in Figure 1, the schematic flow sheet of this project enforcement.
One, preparation of construction
The relative elevation of rack embedded board on civil engineering bearing surface is all measured and is indicated in the corresponding position of plane drawing by civil engineering unit application level instrument, and this datagram is supplied to project supervision and rack installation engineer, as the foundation of installing and check and accept each supporting-point repetition measurement.
Two, construction march into the arena material divide
Rack adopt scaffold coordinative construction platform assembled formation standard across, then install to assembled unit Assembly in pieces at height, from installing to another side on one side, standard across the emphasis being installed as this installation.Rack component, as rod member, bolt sphere, will carry out taxonomic revision in a pre-installation, by specification size, numbering kind marshalling in order, is convenient to search use in installation process.Then the rod member needing to install, bolt sphere are arranged out by the sequencing installed, after everything preparation is carried out, just can carry out the installation on ground of rack.Before installing, bolt sphere classification is put.
2, rod member for grid becomes assembled unit according to erection sequence well at installation on ground, puts by construction location.
Three, start to walk the assembled of rack
1, lower edge plane grid is installed, by first across bearing installation in position, install first across lower bolt sphere, a lower chord, composition fore-and-aft plane grid, as shown in Figure 6A; Sequence interim fulcrum, ensure that lower bolt sphere is in same level; Install the web member between first module and upper bolt sphere, the junior unit of to be generally first cone be ball four web member, is screwed into lower bolt sphere after in place, fixes, as shown in Figure 6B; Second pyrometric cone of having bored as first filling ball one chord member two web member, as shown in Figure 6 C, then inserts other two web members, as shown in Figure 6 D, and the progressively rack of the complete first module of cycle installation, as illustrated in fig. 6e.
2, the inverted triangle grid that winds up is installed; Rack second unit rise adopt limit continue install assembling, as fig 6 f illustrates, first wind up a ball one pyrometric cone 7 of two web members from end bay, be that a ball two winds up the quadrangular pyramid 8 of two web members later, two diagonal web members are supported in lower bolt sphere, strain upper chord up, make upper chord progressively near mounted upper bolt sphere, be screwed into.
Four, the high altitude bulk of follow-up rack
Assembly in pieces at height the component of rack (base parts and components or assembled unit) is winched to design attitude directly carry out assembled method.When adopting suspender to assist installation at high altitude method, the amount of deflection of rack installation process should be controlled, otherwise should take to increase the measure supported, scaffold or steel column need be set up on ground and support and install.
1, base parts and components is spliced into assembled unit;
Rack is reasonably divided into various assembled unit according to actual conditions: such as, is directly always combined into rack by single rod member, individual node, ball one bar, two ball one bars.Or such as, by assembled unit, ball four bar (corner cone), ball three bar (triangular pyramids) are always combined into rack; Again such as, form intermediate combination unit by assembled unit and be always combined into rack again.
2, temporary support point is arranged: temporary support point is arranged and undertaken by rack erection sequence, and supporting-point is arranged should be even.Should control at below 5mm by the total settlement that the factors such as the joint distortion of supporting bracket, elastic compression, foundation settlement cause, supporting-point place can arrange the jack adjusting absolute altitude between rack lower edge and support.
3, grid structure with bolt-sphere joints is always spelled:
Bolt-ball net frame first, across when starting assembled, is generally first spell lower edge, after the absolute altitude of lower edge, axis trimming is good, all tight a bolt, plays the role of positioning.
Then carry out connection web member and wind up.In construction, general employing is by the assembled unit being combined into quadrangular pyramid with web member that winds up, and carries out the installation of assembled unit.The bolt of each assembled unit should be tightened simultaneously, and indivedual bolt should be prevented during construction by jam-packed, causes bolt not effectively to be in place.
Later lower edge and another side web member can adopt single-piece to install, and the method for installing quadrangular pyramid also can be adopted to install.The installation of above-mentioned steps is carried out in circulation, completes the installation of whole rack.It is a row with a grid that rack is installed general, advances by row.
4, net rack support dropping place:
Supporting-point after net rack support dropping place refers to that rack is assembled and completes on striking, makes rack by the operating process of temporary support state smooth transition to the permanent bearing of design.Rack dropping place should follow following principle: declined realized load equilibrium transfer by the jack be placed on the bearing trace that repeatedly circulates during the dismounting of temporary support.Need before dropping place to check whether the descending stroke of jack meets the requirement of this deflection value, the value because rack sinking causes stroke to increase when calculating jack stroke, will be considered, accordingly reserved enough stroke surpluses.
Five, the inspection of rack and measurement and subsequent treatment
After whole rack installation, must check comprehensively, check whether bolt is tightened, and now jackscrew should be in the position of high-strength bolt keyway deep trouth.Whether the parts such as all rod members, ball are installed correct, with or without distortion.The amount of deflection of rack longitudinal direction, lateral length, bearing absolute altitude and off-centring, rack deadweight should be measured.
The allowable variation (mm) that steel grid structure is installed
The subsequent treatment of rack
Rack installs rear bolt sphere to touching off in work progress, sleeve paint carries out benefits and brushes, and unnecessary cavity and gap oil loam block.
Each technical characteristic of above-mentioned disclosure is not limited to that disclosed with combination that is further feature, other combination that those skilled in the art also can carry out between each technical characteristic according to the object of invention, is as the criterion with the object realizing the present invention.
