Detailed description of the invention
Fig. 1 is the utility model structure diagram.
In figure: 1- adjusting angle steel, 2- adjusting hole location, 3- adjusting square steel, 4- hound, 5- bolt positioning plate, 6- location hole,
7- concrete pouring hole, 8- horizontal ruler, 9- fixed frame, 10- connecting hole.
Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples: adjustable four towers base as shown in fig. 1
Plinth foundation bolt is fixed and levelling device, including being spliced into rectangular box-like fixed frame 9, is connected and fixed between fixed frame adjacent edge
Hound 4 and bolt positioning plate 5 positioned at four vertex positions of fixed frame.
Each side of the fixed frame 9 is by the adjusting square steel 3 at middle part and the scalable set in both ends with the adjusting square steel
A pair of angle steel 1 that adjusts connect forms, and is equipped with multiple adjusting hole locations 2 on adjusting square steel and the web for adjusting angle steel, adjusts hole location 2
When being vertical, adjusts hole location 2 and penetrate the top bottom steel plate for adjusting square steel and the horizontal wing plate for adjusting angle steel；Adjusting hole location 2 is laterally
When, it adjusts hole location 2 and penetrates the opposite sides steel plate for adjusting square steel and adjust the vertical wing plate of angle steel.Adjusting side is passed through by bolt
Steel and the adjustings hole location for adjusting angle steel, which will adjust square steel and adjust angle steel, fastens the side for fixed frame, since adjusting angle steel can be
It adjusts in square steel and stretches, therefore, the adjustable variation of side length after fixing can be adapted for difference with opening length after reconciling
Four Guan Tieta.
The both ends of the hound 4 are equipped at intervals with multiple adjusting hole locations, pass through hound 4 by bolt and adjust square steel
Adjusting hole location by hound and adjust square steel fastening.Multiple hole locations that adjust can make hound be connected across the span for adjusting square steel
It is adjustable, to be suitable for different four Guan Tieta with opening length.
The bolt positioning plate 5 is the plate equipped with concrete pouring hole 7, location hole 6 and connecting hole 10, the concrete
7 diameter of pouring hole is 210~230mm, for passing through and leveling after-pouring concrete and fix across foundation bolt.
The location hole 6 is corresponding with the Bolted Flanged Connection hole site on foundation bolt, connects for fastening with bolt flange
Connect and adjust height.
The connecting hole 10 be used for vertically adjacent to two adjustings Bolted angle connections fix, in figure of bowing bolt positioning plate 5 often
There are two the connecting hole 10 in one direction is set, the connecting hole 10 of two vertical direction almost extending line intersection point in bolt positioning plate 5
Center.The center of concrete pouring hole 7 is relative to the angle cleat extending line intersection point connected on the bolt positioning plate 5
52~60mm of outer shifting.It can reduce the area of bolt positioning plate 5.
It is parallel to and adjusts square steel 3 and hound 4, adjust square steel 3 with each respectively and hound 4 is fixed with horizontal ruler
8.The levelness of adjusting can easily be viewed at any time during the adjustment.Specific control method are as follows: 1 square steel and and its
Horizontal ruler is placed respectively on adjacent 2 oblique pull angle steel, after determining absolute altitude, first adjusts the anchor bolt height at 1 square steel both ends
Make on square steel horizontal ruler horizontal, no longer adjusted behind this two anchor bolts, select one oblique pull angle steel see horizontal ruler whether water
Flat, the anchor bolt height not adjusted where the side that adjusting is connected with the oblique pull angle steel if unhorizontal is up to horizontal, so
Herewith method adjusts another oblique pull angle steel horizontal ruler level again afterwards.
As embodiment, previous foundation bolt is to be fixed by 65 meters of long steel pipes with fixture, in this way it is difficult to ensure that four
Foundation bolt forms a square and is able to satisfy various required precisions, and each foundation bolt is also possible that the feelings of torsion
Condition, adjustment is got up, and there is also very big errors for not only troublesome time-consuming.Since above steel pipe, without specific scale, ruler can only be taken
Measurement, little by little adjustment is fixed, and fix one side fixed other positions again, each anchor bolt than heavier, such as with open away from
From one for 45 meters with regard to 243kg, four towers are that have 4, it is easy to get partial or be the central axis on single basis oneself
Away from having turned round or high or low or be exactly that two anchor bolt spacing are again dynamic during the adjustment, constantly to adjust
, scene needs 5 people almost to adjust the time could to have adjusted using this steel pipe is fixed.The utility model can be big
To save regulating time.
Selection is zinc-plated 50 angle steel, 50 square steel and 5mm meter thickness square steel plates in the utility model embodiment, by numerically-controlled machine tool into
Row processing carries out size design in strict accordance with design drawing, and four standards opened according to steel tower root, formulation four is corresponding respectively
Size, the root that four sizes respectively correspond four kinds of four towers of height are opened, and 45 meter Ta Genkai are 3650mm, and 40 meter Ta Genkai are
3300mm, 35 meter Ta Genkai are 2950mm, and 30 meter Ta Genkai are 2600mm.
The utility model is a set of fexible unit, is processed according to drawings marked, opens the group that size determines side according to root
Dress mode, each is opened a kind of corresponding side length.It carries out accordingly assembling as needed, the application of this mold not only makes four
Foundation bolt is appearance that is stringent rectangular and avoiding torsion situation, not only increases the adjustment fixed precision of foundation bolt and big
The big difficulty for reducing construction.In embodiment, it is 1150~1190mm according to the length for adjusting angle steel 1, adjusts square steel 3
Length be 2000~2100mm, the length of hound 4 is 1800~2200mm；It adjusts square steel 3 and hound 4 respectively symmetrically divides
4 pairs of adjustment hole positions 2 are furnished with, the outer end for adjusting angle steel 1 is equipped with connection through-hole corresponding with the connecting hole of bolt positioning plate 5, adjusts
It saves on angle steel 1 at least provided with three pairs of connection through-holes corresponding with the adjusting adjusting hole location of square steel 3.While by the tune of 2 root long 1175mm
Angle steel and the adjusting square steel composition of 1 root long 2060mm are saved, the hole that spacing is 175mm on angle steel is adjustment hole, the angle at square steel both ends
Steel is symmetrically installed, and using first hole of square steel outermost end as benchmark hole, when 45 meter Ta Genkai makes datum hole and adjusts the 3rd, angle steel
Adjustment hole is overlapped, and when 40 meter Ta Genkai is overlapped datum hole with adjusting the 4th adjustment hole of angle steel, and when 35 meter Ta Genkai makes datum hole
Is overlapped with the 5th adjustment hole of angle steel is adjusted, when 30 meter Ta Genkai is overlapped datum hole with adjusting the 6th adjustment hole of angle steel.According to
Steel tower root, which is opened, calculates corresponding side length, while being made of 2 angle steel and 1 square steel, square plate is 4 for being fixed on foundation bolt
It is adjacent on screw rod and with foundation bolt flange, material selection numerically-controlled machine tool is processed, and side length exists after being fixed by specified hole
Root is opened in allowable range of error.
It is attached by different hole locations with bolt, with opening length consolidating suitable for different height iron tower base foundation bolt
Fixed and leveling.In work progress, transport, dismantle and install simple to operation, this device ensures between corresponding anchor bolt center
Control away from, each foundation bolt height and each foundation bolt torsional deflection equally accurate.Solving in traditional construction is fixed lower margin
Bolt, control precision is taken a lot of work laborious phenomenon, so that labor intensity reduces significantly.
