Steel cushion block is respectively provided with below each fixed frame, for fixed frame it is in place after be adjusted.
The quantity and installation site of the prestress wire, according to the mechanics parameter of foundation pier and bolt embedment box
Position is configured.
The top setting of four fixed frames transversely and horizontally supports relative position and overall stability to ensure fixed frame.
In the following, the program is described in detail for building two daily outputs, 10,000 tons of cement producing lines:
The core equipment of cement producing line is " two one kilns of mill ", and 2 425 ton/hours of raw materials mills of every line configuration are former
It is designed in material mill basis laterally and vertical two kinds of prestressing force arrangement, the effect of prestressed installation and tensioning directly affects grinding machine knot
Structure construction quality.
The prestress wire group number of direction in length and breadth that raw material grinds grinding machine basis is more, in order to guarantee vertical prestressing steel strand wires
Position is accurate, then must assure that the accurate of corrugated bushing installation site；In order to ensure the precision of corrugated bushing installation, this is devised
Raw material grinds vertical prestressing steel strand wires corrugated bushing mounting and fixing support.
There are 4 vertical foundation piers on the grinding machine basis of each raw material mill, and each foundation pier has 11 beam vertical prestressing steel strand wires,
Totally 44 beam, every beam prestress wire include the prestress wire composition of 19 diameter 15.7mm, and steel strand wires pass through pre-buried straight
Diameter is the vertical corrugated bushing of 100mm, so that steel strand wires are mounted on design position.
Vertical prestressing steel strand wires corrugated bushing flow of installation are as follows:
Making fixed frame, --- fixed frame is installed in place, and --- fixed frame adjustment --- bellows is placed and is fixed.
Specific implementation step is as follows:
Fabrication and installation fixed frame:
The raw material mill high 8m of foundation pier that is placed of vertical prestressing steel strand wires, while having bolt embedment box etc. other interspersed are made
Industry, concreting must be completed by several times, in order to ensure stabilization of the steel strand wires bellows in each concreting process, system
Make the fixed frame of the special fixed steel strand wires.The positioning of position based on each presstressed reinforcing steel when the fixed frame makes, and take into account
The fixation of bolt embedment box etc. fully considers the evacuation to main structure reinforcing bar and embedded part etc..Using the conventional material such as angle steel, channel steel
Material production.It can be assembled nearby.
Fixed frame is installed in place:
The fixed frame processed is transported, is lifted on the coordinate of telltale mark, can be used in total station fixed frame
Heart coordinate is thrown on the bed course on basis, is then divided the position of 4 brackets of fixed frame, is first placed on 4 pedestals of steelframe
Parallels, convenient for the adjustment after in place.Parallels checks the absolute altitude at 4 angles with level after putting well, relative error controls in ± 5mm
Afterwards, fixed frame is placed to designated place.
The adjustment of fixed frame:
Vertical line is marked on the two-dimentional axis direction of fixed frame with theodolite, is adjusted and is fixed by inclined sizing block (i.e. steel cushion block)
The other side is adjusted in frame, the gradient at four angles, side again after adjusting, the deviation control at frame top and frame bottom is in ± 3mm.It adjusts
Afterwards, corresponding position drills on steel plate 8, is fixed using M10 expansion bolt, the first expansion bolt 6 is respectively set in four angles
With the second expansion bolt 7, the first expansion bolt 6 and the second expansion bolt 7 are identical parts, and attached drawing is just to distinguishing two
The restriction that the structure in face is made；Column 2 is mounted on 10mm steel plate 8, the corresponding drilling in four angles of 10mm steel plate 8, the rule of column 2
Lattice select L80*8.
Bellows is placed and is fixed:
Steel strand wires bellows 12 can be by the node diagram being pre-designed, the present embodiment such as Fig. 9, welds on lateral reinforced steel 4
Two pieces of 6mm fixation steel plates 9 disposed in parallel are respectively provided with two perforation of ￠ 8 11 on every piece of 6mm fixation steel plate 9, iron wire 10 are passed through
Threading hole fixes bellows and steel framework.
All steel strand wires can first be assembled with prestressed anchor bottom end before filling fixed frame, then by assembled steel
After twisted wire harness penetrates in bellows, anchorage and bellows seal interface, such as use adhesive tape.After fixed frame installs,
The bellows with steel wire bundle is installed on fixed frame respectively.
Above-mentioned all sizes are illustrated as specific example, and different demands can choose different sizes, cannot
As uniquely needing scheme to be protected.
It is vertically pre- that the installation method very good solution of vertical prestressing steel strand wires multi beam is installed by pre-manufactured steel fixed frame
Prestress steel strand supports and fixes problem, it is ensured that the precise mounting position of steel strand wires bellows makes it not by reinforcing bar and coagulation
The influence of geotechnological journey segmentation operation.
Mounting process feature: installation speed is fast, and fixed accurate, installation accuracy is high, quality assurance, and construction safety, economy are real
With.
Connection relationship, treating method between structure mounting means of the invention, component are merely possible to an example
Illustrate, must not believe that and only protect the scheme, it is all to the device as installed under prestressing fixed frame in the case where all
It is referred to the methods of this programme.
Those skilled in the art can make various modifications to described specific embodiment
Or supplement or be substituted in a similar manner, however, it does not deviate from the spirit of the invention or surmounts the appended claims determines
The range of justice.
