Description

Technical Field

[0001] The utility model relates to the technical field of pre-embedded bolt installation, in particular to a pre-embedded bolt installation and positioning device for a round steel column foot. Background Art

[0002] Embedded bolts are crucial components connecting steel columns to concrete foundations and must be installed in designated locations according to design drawings. The accuracy and verticality of embedded bolt installation are crucial factors influencing project construction quality. However, current research on bolt positioning devices for embedded bolts in circular steel columns is insufficient, resulting in a lack of comprehensive, high-performance positioning devices.

[0003] Since most of the work of pre-embedded bolts is completed by the civil engineering team, this also leads to poor overall construction quality of the pre-embedded bolts. During the pre-embedded bolt construction operation, the position of the pre-embedded bolts is not accurately positioned; the positioning device does not take the verticality and tightness of the pre-embedded bolts into consideration, which also leads to poor verticality of the pre-embedded bolts during on-site pouring, and the steel column base plate cannot be installed in place, and even requires corresponding hole expansion measures. The pre-embedded bolt installation and positioning devices currently on the market have complex working principles, require multiple people to operate, are difficult to operate, and are not reusable, which also leads to further increases in construction costs. Therefore, a pre-embedded bolt installation and positioning device for round steel column bases has been developed that is simple to operate, has high installation accuracy, and is easy to carry. Summary of the Invention

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a pre-embedded bolt installation and positioning device for a round steel column base, wherein an annular pre-embedded bolt positioning space is formed between the annular outer surface of the scale positioning plate and the annular inner surface of the auxiliary plate, and the pre-embedded bolt is clamped with the scale positioning plate by a fastening nut passing through the auxiliary plate, so as to accurately locate the position of the pre-embedded bolt, thereby ensuring the verticality and tightness of the pre-embedded bolt during on-site casting, and the steel column base plate is accurately installed in place, reducing the difficulty and complexity of operation, and is reusable, simple to operate, and reduces construction costs.

[0005] The utility model solves the technical problem by the following technical solutions:

[0006] A device for installing and positioning embedded bolts at a round steel column base comprises a scale positioning plate, a bolt height control nut, a bolt height control plate, an auxiliary plate and a fastening nut; the scale positioning plate and the auxiliary plate are coaxially installed via symmetrical connecting pieces, an annular embedded bolt positioning space is formed between the annular outer surface of the scale positioning plate and the annular inner surface of the auxiliary plate, and a plurality of fastening nuts are arranged at annular intervals on the auxiliary plate; a bolt height control plate is coaxially installed at the upper end of the scale positioning plate, and the height of the bolt height control plate is adjusted by the bolt height control nut installed at the center thereof.

[0007] Furthermore, a handle is installed on the upper end of the scale positioning plate, and a bolt height control nut is installed at the center of the handle for adjusting the height of the mounting bolt height control plate.

[0008] Furthermore, a plurality of horizontal bubbles are formed on the circumference of the upper end of the scale positioning plate to adjust the horizontality of the positioning scale plate.

The scale positioning plate 1 is clamped, and the auxiliary plate 7 fastens the embedded bolts 9 to the outer wall of the scale positioning plate 1 through the tightening nut 10, which can not only adapt to the embedded bolts 9 of different sizes, but also meet the requirements for bolt tightness; the bolt height control plate 5 is coaxially installed on the upper end of the scale positioning plate 1, and the height of the bolt height control plate 5 is adjusted by the bolt height control nut 4 installed at the center thereof; the bolt height control nut 4 and the bolt height control plate 5 adopt a fixed rotation connection method, and the upper and lower heights of the bolt height control plate 5 are adjusted by turning the bolt height control nut 4, thereby controlling the height position of the embedded bolt 9.

[0021] The scale positioning plate 1 is circumferentially formed with a plurality of leveling bubbles 2 for adjusting the levelness of the scale positioning plate. A handle 3 is mounted on the top of the scale positioning plate 1, with a bolt height control nut 4 mounted in the center of the handle for adjusting the height of the bolt height control plate 5. The handle 3 facilitates the portability of the scale positioning plate 1 and provides space for the bolt height control nut 4 to adjust its height up and down.

[0023] The working principle of this utility model:

[0024] First, assemble the embedded bolt installation and positioning device of the round steel column base: use the auxiliary connecting piece 8 to splice the two semi-crescent ring plates into an auxiliary plate 7, and fix it with nuts; use the connecting piece 6 to connect the auxiliary plate 7 with the scale positioning plate 1; install the handle 3 on the scale positioning plate 1, install the bolt height control nut 4 in the center of the handle 3, and the lower end of the bolt height control nut 4 is threadedly connected to the bolt height control plate 5.

[0025] Hold the handle 3, level the scale positioning plate 1 using the level bubble 2 on the scale positioning plate 1, and use the scale lines to determine the absolute position of the round steel column. Confirm the position of each embedded bolt 9 according to the design drawing, and mark the corresponding scale lines on the scale positioning plate 1. Insert the embedded bolt 9 into the gap between the scale positioning plate 1 and the auxiliary plate 7, and use the bolt height control nut 4 to change the relative height position of the bolt height control plate 5 from low to high to meet the design requirements. When the height is properly controlled, place the embedded bolt 9 at the pre-marked scale line position, and use the fastening nut 10 to fix the embedded bolt 9 tightly against the outer wall of the scale positioning plate 1 to meet its verticality and tightness requirements, and finally cast the embedded bolt 9.
