Abstract
The utility model discloses a mounting and alignment guide screw of a high-rise steel structure box column lead screw, belonging to the technical field of steel structure mounting and mainly solving the problems of great difficulty and longer period existing in both arrangement of a hawser cable and micro adjustment in a column alignment process of the conventional mounting process. The mounting and alignment guide screw is mainly characterized by comprising a screw, a steel pipe, a carbon steel plate and a lug plate, wherein the screw is provided with a section of fine thread lead screw; one end of the screw is fixed to the lug plate through a pin; the carbon steel plate is provided with an internal thread hole which is matched with the fine thread on the lead screw; the steel pipe and the lug plate are sleeved on the plane of the lower end of an operation layer in a welding manner; and the lead screw is manufactured by welding the screw, the lug plate and plug plate sealing heads at the two ends. The mounting and alignment guide screw has the characteristics that the mounting and the alignment of the high-rise steel structure are greatly improved in material, operability and operation method compared with the conventional mounting and alignment method, and the guide screw is mainly used for the mounting and alignment lead screw for alignment in an aerial grouped mounting process of a multi-section column.
Description
Technical field
The utility model belongs to the Installation Technology of Steel Structure field.Be specifically related to a kind of installation centering leading screw for organizing at Multi-section column the installation process centering in the air.
Background technology
In the Steel Structure Installation process, the aerial group of Focal point and difficult point of installing being mounted for high-rise steel structure of Multi-section column.How safe, efficient aerial group of post finished is right, becomes the vital factor of high-rise steel structure installation period that shortens.In traditional mounting process, our job practices mostly adopts behind the steel column hoisted in position, before the crossbeam connection, adopts cable wind rope and fishplate or junction plate is finished fixing, the adjustment work of steel work.This kind method all exists very large difficulty and cycle longer in the setting of cable wind rope and the fine setting in the post centering process.
Summary of the invention
The purpose of this utility model is exactly to provide for above-mentioned weak point a kind of and had both solved existing complicated cable wind rope problem is set, and can finely tune in centering is regulated again, and the extraordinary high-rise steel structure box column of effect screw mandrel is installed the centering leading screw.
Technical solution of the present utility model is: a kind of high-rise steel structure box column screw mandrel is installed the centering leading screw, it is characterized in that: comprise screw rod, steel pipe, carbon steel sheet, otic placode; Described screw rod is provided with one section fine thread screw mandrel; Screw rod one end is fixed on the otic placode by pin; Carbon steel sheet is provided with the internal thread hole that cooperates with the screw mandrel fine thread; The welding of steel pipe and otic placode is sleeved under the work layer on the transverse plane; Leading screw is formed by the closure plate end socket welding production at screw rod, otic placode and two ends.The screw thread at leading screw two ends must be complete, i.e. " a positive and a negative ".Need symmetry to open the circular hole of 3 ~ 5 centimetres of diameters at the steel pipe near the leading screw lower end.
Spiro rod length described in the technical solution of the present utility model is 500mm, and the screw mandrel length on the screw rod is 300-350mm.
The utility model is by screw mandrel, otic placode, and the leading screw that forms of the closure plate end socket welding production at two ends, screw rod is provided with one section fine thread screw mandrel, screw rod one end is fixed on the otic placode by pin, carbon steel sheet is provided with the internal thread hole that cooperates with the screw mandrel fine thread, steel pipe socket is contained in, thereby " leading screw " end and lower floor's girder steel are welded and fixed when using, another the section with fixed by the centering steel column, utilize transit to carry out squareness measurement to being mutually 90 ° of directions, utilize crowbar to rotate " leading screw " the survey error is regulated, be whole " leading screw " installation centering process of finishing until be adjusted into standard allowed band error.The utlity model has to high-rise steel structure install, centering is compared traditional installation, aligning method has all been made larger improved characteristics on material, operability, method of operating.The utility model is mainly used in the installation centering leading screw of centering in Multi-section column is organized installation process in the air.
Adopt " leading screw " regulating system to carry out the centering of steel work, both solved complicated cable wind rope problem is set, in centering is regulated, finely tune effect very good again.
Description of drawings
Fig. 1 is the structural representation of screw mandrel.
Fig. 2 is the structural representation that connects otic placode.
Fig. 3 is the structural representation of leading screw.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1 to Figure 3.The utility model high-rise steel structure box column screw mandrel installation centering leading screw is formed by the closure plate end socket welding production at screw rod 1, otic placode and two ends.Screw rod 1 one ends are connected on the otic placode by pin 5, and the other end is provided with M41 external screw thread 2.Screw rod 1 length is 500mm, and the screw mandrel length on the screw rod 1 is 300-350mm.δ 40 carbon steel sheet centers processing M41 internal thread 4 matches with external screw thread 2 on the screw rod 1.Carbon steel sheet is positioned at φ 89 * 4.5 steel pipes 3.The closure plate end socket is made of tapped carbon steel sheet, welding is installed is positioned at sleeve pipe.
Operating procedure:
(1), finish above material and make after, " leading screw " end and the lower floor's girder steel that completes is welded and fixed another section and being fixed by the centering steel column;
(2), utilize transit to carry out squareness measurement to being mutually 90 ° of directions, utilize crowbar to rotate " leading screw " the survey error regulated, be whole " leading screw " installation centering process of finishing until be adjusted into standard allowed band error.
Operation notice:
(1), " leading screw " preparatory work before installation: the two ends of " leading screw " are fixing by otic placode and connecting bolt, need carry out in advance in the permanent position built-in fitting if the beam of lower end is concrete beam;
(2), the permanent position of " leading screw ": leading screw at first must be determined its permanent position before installation, main definite principle has: at first will guarantee to be installed in and be easy to the constructor and install and the position of removing, it is less important guarantees that the position of installing does not affect the girder steel of lower end and supports and install;
(3), the circular hole opened of the steel tube place of leading screw lower end should symmetrically distribute and be convenient to insert the crowbar rotational lead screw verticality of steel work is adjusted.
Adopt " leading screw " centering technology to adjust on the number of tools and the centering time is compared conventional method larger progress has been arranged firm, not only saved the measure materials but also saved the construction labour cost, greatly reduced construction cost.Adopting simultaneously " leading screw " centering technology to compare conventional method in the handling safety performance more has safety guarantee, therefore " leading screw " centering technology is the new technology that the construction of high-rise steel structure centering is worthy of popularization.Believing in similar engineering construction from now on and can be widely used, have the stronger market competitiveness, is a construction technology that is worthy to be popularized.
