The steel pipe plant room column is welded into an outer wall by the spiral welded pipe, is filled with self-compacting concrete into a whole, has the characteristic of low cost compared with the steel pipe plant room column, and is widely adopted by various design units so as to reduce the construction cost.

At the present stage, a column center line and a cup mouth center line are drawn in advance before a steel column is installed, a sizing block with a proper height is padded at the bottom of the cup mouth to reach a designed elevation, and then a crane is used for hoisting the column into the poured cup mouth. At the moment, the steel column is suspended in the cup opening, after the steel column is stabilized, the center line of the walking steel column adjusting steel column is aligned to the center line of the cup opening, and the steel column is placed on the sizing block in the cup opening. And (4) accurately positioning in two directions by using a hydraulic jack to align the cross lines, and finally fixing and welding by using a wedge iron. The installation mode has long installation period because the installation mode needs secondary alignment, and the jack needs to be screwed in two directions simultaneously when the installation mode is accurately aligned, so that the installation mode has the defects of more manpower resources, inconvenient operation, easy excessive adjustment and multiple adjustments, and difficult achievement of the relevant regulation that the deviation of the steel column is within 3mm in the steel structure engineering construction quality acceptance standard (GB 50205-2020) of the national specification.

Therefore, in order to reduce unnecessary trouble in the subsequent installation process, the use amount of operators and tools is reduced, and the safety is improved. There is a high necessity to develop an easily operated, easily used and safe auxiliary device for accurate positioning of a column of a factory building.

Disclosure of Invention

The utility model aims at providing a device for factory building post center location has solved the not high problem of steel column precision in the installation, improves installation adjustment speed, improves operating personnel security.

A device for factory building post center location constitute by identical two parts, use bolt, spring washer, nut to fix an organic whole, the steel ring that the center formed is embraced on the factory building post, the steel sheet top of four directions is on the wall on rim of a cup four sides on every side.

A center positioning device for a factory building column comprises a hoop 1 and a fixing plate 4; the fixing plate 4 is fixed on the hoop 1 through the first nut 2 and the second nut 3, the two hoops 1 form two complete half bodies, and two sides of the two half bodies are fixed through the third nut 5, the spring washer 6 and the fourth bolt 7 respectively to form a complete device.

Staple bolt 1 include an arc steel sheet, four gussets and two foraminiferous steel sheets, four gussets of the outer even welding of an arc steel sheet, the other end welding of two adjacent gussets has a foraminiferous steel sheet, two staple bolts 1's arc steel sheet forms a circle that can hold the post tightly after connecting.

The fixing plate 4 is formed by welding a bolt perpendicular to the steel plate, and the bolt penetrates through a preformed hole of the steel plate with the hole on the hoop 1.

The utility model has the advantages of simple structure, light weight, low investment and easy processing and manufacturing. Each set of device can be repeatedly utilized for many times, the operation is simple, and one person can carry out installation and positioning operation. And the device greatly improves the positioning precision of the factory building column, avoids the problems possibly occurring in the subsequent installation process to a certain extent, avoids the work and rework, and indirectly improves the labor productivity.

Detailed Description

In order to make the technical field better understand the solution of the present invention, the following detailed description of the present invention is provided with reference to the accompanying drawings and the detailed description.

The utility model discloses a staple bolt 1, nut 2, nut 3, fixed plate 4, nut 5, spring washer 6, bolt 7 are fixed as an organic whole.

The hoop 1 is composed of two identical parts, and is formed by welding an arc-shaped steel plate, four rib plates and a steel plate with holes.

The fixing plate 4 is composed of four identical parts, and is welded with a steel plate into a whole by bolts which pass through holes of the steel plate with holes to be connected into a whole.

Nut 2, nut 3 are the same completely, and nut 2, nut 3 are connected fixed plate 4 on staple bolt 1, and nut 3 is used for adjusting the extension length of fixed plate 4 and then adjusts the factory building post position, and nut 2 is used for spacing and prevents that fixed plate 4 from breaking away from staple bolt 1.

The hoop 1 is butted together by the nut 5, the spring washer 6 and the bolt 7, and a circular shape is formed in the center to hold a steel column of a factory building.

Preferably, four fixing plates are arranged in the circumferential direction and used for propping against the inner wall of the cup mouth, so that the adjustment is facilitated.

Preferably, the hoop fitting surface and the central line of the fixing plate are arranged at a certain angle, and enough wrench space is reserved. The hoop arc plate and the fixed plate bolt are staggered from top to bottom by a certain distance, so that interference with the anchoring nail at the bottom of the plant column is avoided.

Preferably, the positioning device can accurately position the factory building column by fixing the device at a proper position on the factory building column to be installed and screwing the nut 3 by using a wrench.

As shown in fig. 1, the fixing plate 4 is fixed on the hoop 1 through the nut 2 and the nut 3 at a right angle to form two integral half bodies, and the two half bodies are fixed on the plant-house column by using the nut 5, the spring washer 6 and the bolt 7 before the plant-house column is hoisted. The factory building column is hung into the cup mouth, the bottom of the factory building column is aligned to the pre-adjusted sizing block and hovers, and the position of the device is adjusted to enable the upper surface of the fixing plate to be lower than the upper surface of the cup mouth. The position of the limiting nut 2 is adjusted to ensure enough adjusting distance, and the planes of the four fixing plates are tightly attached to the inner wall of the cup opening.

And fastening the nuts 3 according to the center line of the cup opening and the center line of the steel column drawn in advance, loosening the nuts 3 on the opposite sides at the same time, aligning the center lines of the steel column in one direction, and adjusting the position in the other direction in such a way. After the central line is completely aligned, the steel column falls to the sizing block by means of gravity, the device is taken out from the cup opening after all the nuts 3 are loosened, the wedge is symmetrically plugged into the welding die, and the positioning accuracy of the plant room column is guaranteed. After the installation process of the plant column is completed, the nut 5, the spring washer 6 and the bolt 7 are loosened, the device is divided into two bodies to be taken down, and the next installation is waited.
