Description

Built-in steel pipe column guiding and positioning device

Technical Field

The utility model relates to a built-in steel pipe column guiding and positioning device which can be used for quickly, safely and reliably butting an upper section steel column with a lower section steel column, and has the advantages of convenient operation, high efficiency, accurate control precision, wide application range and reusability.

Background

The steel pipe column is applied to the manufacturing of building steel structures and bridge steel structures, generally long and large pipe fittings are adopted, single pipe joints are manufactured in factories, and the steel pipe columns are lengthened on site and welded through circumferential seams. In the steel pipe column installation and construction process, a crane is generally utilized to hoist the steel pipe column to a connecting position for positioning, and then a code plate or a matching piece is adopted to temporarily connect and fix the upper pipe section and the lower pipe section. When the field pipe joint is suspended and positioned, the swing amplitude is too large, so that the pipe joint is difficult to hoist to a designated position at one time, and great difficulty is brought to quality control and safety management. In particular, for pipe fittings with complex connection relationships and stresses, field interface matching becomes a key for quality control. The following problems exist in the vertical connection and positioning of the traditional steel pipe column (long thin rod piece): firstly, the positioning guide reference is lacking, a crane driver is mainly relied on to visually feel, the crane is operated to slowly hang and drop the steel pipe column to a designated connecting position, and in the process, the steel pipe column swings in the air, so that the positioning process is slower, the driver is required to repeatedly operate for a plurality of times to finish the alignment work, and the efficiency is lower; secondly, when the traditional code plate or matching piece is positioned and the pipe is in a falling position, manual auxiliary alignment is needed, but the steel pipe column lacks transverse limit and swings back and forth in the air, so that collision can be generated to operators and brackets, and a large potential safety hazard exists; thirdly, traditional code plates or matching pieces are positioned and need to be welded with a steel structure in advance, the later-stage cutting and relief grinding workload is large, certain damage is caused to components, and the structural durability is affected.

Disclosure of Invention

The design purpose is as follows: the defects in the background technology are avoided, and the built-in steel pipe column guiding and positioning device which can be used for rapidly, safely and reliably butting the upper section steel column with the lower section steel column, is convenient to operate, high in efficiency, accurate in control precision and wide in application range and can be used repeatedly is designed.

The design scheme is as follows: in order to achieve the above design objective. The utility model is structurally designed: the built-in steel pipe column guiding and positioning device consists of a guide plate, a bolt and the like. The deflector is constructed as trapezoidal board, and the trapezoidal hypotenuse of deflector is the leading edge, and the leading edge upwards arranges in the column wall side when the deflector is installed, and the bolt hole has been seted up at deflector length direction both ends, and the welding gap of steel column is considered to the interval of both ends bolt hole crowd. When the upper section steel column and the lower section steel column are installed, the upper section steel column is hoisted to a guide area, quickly slides to a positioning installation position under the action of the guide edge of the guide plate, and is temporarily and fixedly connected by bolts. The steel column connecting ports are provided with the guide plates in four directions, so that transverse swing of the steel column in the lifting process is effectively limited, and safe operation of lifting operation is guaranteed.

The technical scheme is as follows: the utility model provides a built-in steel-pipe column direction positioner, includes lower section steel-pipe column, and lower section steel-pipe column inner wall equidistance is equipped with and erects many overlooks and be T type riser, three or four T type risers of equidistance in a plurality of T type risers of lower section steel-pipe column inner wall facial make-up built-in direction positioner.

Compared with the background technology, the built-in guiding and positioning device is designed according to the structural characteristics of the steel pipe column, mainly comprises the guide plate and the connecting bolt, has simple and convenient tool manufacture and strong operability, and is convenient for field implementation; secondly, the built-in guiding and positioning device can rapidly and accurately match the ring openings, has strong practicability, is beneficial to shortening the positioning period and improving the installation efficiency; and thirdly, after the built-in guide device is positioned, the guide device can be quickly removed and can be reused, so that the field connection positioning welding operation is reduced, and the field construction cost is saved.

Detailed Description

Example 1: reference is made to fig. 1-4. The utility model provides a built-in steel-pipe column direction positioner, includes lower section steel-pipe column, and lower section steel-pipe column inner wall equidistance is equipped with and erects many overlooks and be T type riser, three or four T type risers of equidistance in a plurality of T type risers of lower section steel-pipe column inner wall facial make-up built-in direction positioner. The guide plate 1 and the bolt 2 in the built-in guide positioning device are formed, an upper section steel column connecting screw hole 4 and a lower section steel column connecting screw hole 4 are formed in the guide plate 1, the guide plate 1 is connected with a T-shaped vertical plate through the bolt 2, and the outer side edge of the upper end part of the lower section steel column extending out of the guide plate 1 is a trapezoid bevel edge.

The method adopts a built-in steel pipe column guiding and positioning device to quickly connect an upper section steel column and a lower section steel column in a butt joint mode, 1) a guide plate 1 is fixed in advance by adopting bolts 2 on T-shaped vertical plates in three or four directions on the top inner wall of the lower section steel column to be connected in length; 2) Hoisting the upper section steel column, and rapidly and accurately positioning the axial leads of the upper section steel column and the lower section steel column by utilizing a guide plate extending out of the lower section steel column; 3) After the upper section steel column and the lower section steel column are accurately aligned, the upper section steel column and the lower section steel column are temporarily and fixedly connected through a guide plate and a bolt, and then the upper section steel column and the lower section steel column are welded into a whole through girth welding; 4) After the welding is finished, the upper section steel column enters the guide plate and the bolts to be removed, and then the guide plate and the bolts are reused. For the steel column of long thin member, there is the risk of overturning, in order to guarantee steel column location safety, after the steel column is accurate to be aligned, pass through deflector, bolt temporary fixed connection between upper and lower two sections steel columns. The steel column connecting port is additionally welded with a fixed riser (the length L is larger than or equal to 1m, namely, the connecting port of the upper section steel column and the lower section steel column is additionally welded with the fixed riser, and the length L of the riser is larger than or equal to 1 m), so that the stability of the upper section steel column is ensured.
