Abstract
The invention relates to a method for installing and precontrolling high-strength bolts with a complicated space structure. The method comprises the steps of: selecting connecting plates with the same specification and model, and carrying out alignment drilling on the connecting plates with the same specification and model in a complete set by a fixed mould; assembling a plurality of connecting elements into a mounting unit on the ground by the connecting plates and temporary installation bolts on the ground, lifting the whole mounting unit in position, adjusting and welding; after welding, sequentially replacing the temporary installation bolts by the high-strength bolts, and screwing and fixing the high-strength bolts. A method of firstly welding and then installing the elements in a traditional mode is changed; the method provided by the invention is simple in operation, reduces the times of overhead installation and hoisting, improves the construction efficiency, and reduces the construction cost and safety risk. The connecting plates are cut in a precise or semi-automatic way, and the alignment drilling is carried out on the connecting plates with the same specification and model in the complete set by the fixed mould, so that drilling accuracy and efficiency are guaranteed, the hole passing rate of the high-strength bolts can be further increased, and the connecting plates with the same specification and model have interchangeability.
Description
Technical field
The present invention relates to the installation pre-control method of a kind of coke dry quenching body steel construction and other Complicated Spatial Structure high-strength bolt.
Background technology
Coke dry quenching body steel structure connection form mostly is high-strength bolt and connects, and the method adopted before it is: join factually the brill method, assemble and join brill method, pre-installation method.The pattern of these methods of operating is: first member and column such as connecting short beam welded together, and auger shell keyhole one by one on connecting plate, then work high above the ground is connected short beam by connecting plate with long beam again with high-strength bolt.The weak point of this operator scheme is: 1, loose mail is many, and the aloft work amount is large, and efficiency of construction is low, and potential safety hazard is large; 2, high because space structure is complicated, hole group's quantity reaches the installation accuracy requirement more, it is low that high-strength bolt is crossed porosity; 3, because connecting plate is too much, the bolt hole machining accuracy is low, and connecting plate interchangeability is poor, and installation effectiveness is low.
Summary of the invention
Goal of the invention of the present invention is for the deficiencies in the prior art, and the installation pre-control method of the Complicated Spatial Structure high-strength bolt that a kind of high-strength bolt punching rate is high, simple to operate, efficiency of construction is high is provided.
Realize that above-mentioned purpose by the following technical solutions: a kind of Complicated Spatial Structure is high
The installation pre-control method of strength bolt, comprise connecting plate, connector, high-strength bolt and interim construction bolt; Described method comprises the steps:
A. select specification, connecting plate that model is identical, specification, connecting plate that model is identical are carried out to complete centering boring with fixed mould;
B. some connecting elements are assembled into to an installation unit by connecting plate and interim construction bolt on ground, the installation unit integral hoisting is in place, weld after adjusting;
C. after the welding, jury interim construction bolt is replaced with to high-strength bolt successively, twist solid high-strength bolt and install.
Further, the drilling hole on described connecting plate is apart from equating.
Further, the number of connection of described interim construction bolt is no less than 1/3 of track bolt sum.
Further, described interim construction bolt is evenly distributed on connecting plate.
Adopt technique scheme, compared with prior art, the present invention has changed the method that member in the traditional mode first welds rear installation, first member is assembled into to an installation unit on ground with interim construction bolt, integral hoisting is welded again, and method of operating is simple, has reduced high-altitude the number of times of lifting is installed, improve efficiency of construction, reduced construction cost and security risk.Connecting plate adopts accurate cutting or semi-automatic cutting, the connecting plate of same size adopts fixed mould to carry out complete centering boring, guarantee the precision of holing and efficiency, and then improve the mistake porosity of high-strength bolt, and the connecting plate of same size, model has interchangeability.
The accompanying drawing explanation
Fig. 1 is beam of the present invention ground assembling schematic diagram.
Fig. 2 is that Figure 1A-A is to profile.
Fig. 3 is beam integral installation welding schematic diagram of the present invention.
Fig. 4 is high-strength bolt installation method schematic diagram of the present invention.
In figure, short beam 1, long beam 2, short beam 3, assembly platform 4, connecting plate 5, bolt hole 6, interim construction bolt 7, bolt hole 8, upright of frame 9, weld seam 10, high-strength bolt 11.
The specific embodiment
The present invention will be further described below in conjunction with accompanying drawing.
The invention discloses a kind of installation pre-control method of Complicated Spatial Structure high-strength bolt, this mounting technique is applicable to coke dry quenching body steel construction and the integral installation of other porous group high-strength bolt.The parts that this method is used have: connecting plate 5, high-strength bolt 11.Concrete steps are:
Select connecting plate: select specification, connecting plate that model is identical, specification, connecting plate that model is identical are carried out to complete centering boring with FIxed abrasive article.Boring 6 pitch-rows on connecting plate 5 equate.Not possessing complete connecting plate 5 of joining brill needs to adopt the import core drill to hole, and guarantees the precision of holing and efficiency.
See Fig. 1, connecting plate 5 first is connected with interim construction bolt 7 with long beam 2 with short beam 1, short beam 3; Interim construction bolt 7 numbers of connection be no less than the track bolt sum 1/3 and to be uniformly distributed.
See Fig. 2, installation unit and upright of frame 9 are welded together, stay weld seam 10.
See Fig. 3, after welding, interim construction bolt 7 is changed to high-strength bolt 11 successively, high-strength bolt 11 is evenly distributed on connecting plate 5, twists solid high-strength bolt 11 and installs.
When high-strength bolt 11 is installed, runs into little the adopted reamer of bolt hole 8 dislocation and revise, after correction, carry out again the installation of high-strength bolt 11.
Above-described embodiment has only been expressed one embodiment of the present invention, but can not therefore be interpreted as limitation of the scope of the invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.
