Novel positioning anchor bolt for steel structure stand column

Abstract

This utility model discloses a novel positioning anchor bolt for steel structure columns, comprising an anchor bolt, a nut, a positioning steel plate, an anchoring steel plate, and positioning angle steel. The positioning steel plate is the size of the column foundation and has positioning holes drilled on it according to the position of the anchor bolt. Four positioning angle steels form a rectangular integral structure, with positioning holes corresponding to the anchor bolt positions, allowing the anchor bolt to pass through the positioning angle steel and be placed in the required position. The bottom of the anchor bolt is fixedly connected to the anchoring steel plate to form a whole. This utility model provides a quick and simple anchor bolt positioning method that ensures the positioning accuracy and verticality of the anchor bolts. By using a prefabricated device to fix the anchor bolts before overall construction, it is beneficial to position and adjust the anchor bolt group on site, saving construction units a lot of manpower and time, and creating certain economic benefits.

Description

Technical Field

[0001] This utility model relates to the field of steel structure column construction technology in industrial and civil buildings, and in particular to a new type of positioning anchor bolt for steel structure columns. Background Technology

[0002] With the development of my country's steel industry, steel structures have been widely used in industrial and civil buildings. Anchor bolts, as the basic anchors of steel frames, can transfer the load generated by the steel frame under various working conditions to the foundation. They are an important component of steel frames and also an important component to ensure the safety and stability of steel frames.

[0003] Embedding bolts is the first and crucial step in on-site steel structure construction. However, during on-site construction by civil engineering units, it is difficult to accurately control the elevation and axis of the embedded anchor bolts, making it difficult to control the construction quality. Taking measures to correct deviations is time-consuming and labor-intensive. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model designs a new type of positioning anchor bolt for steel structure columns.

[0005] The present invention adopts the following technical solution:

[0006] A novel positioning anchor bolt for steel structure columns includes an anchor bolt, a nut, a positioning steel plate, an anchoring steel plate, and positioning angle steel. The positioning steel plate is the size of the column foundation and has positioning holes drilled on it according to the positions of the anchor bolts. Four positioning angle steels form a rectangular integral structure, with positioning holes corresponding to the anchor bolt positions, allowing the anchor bolts to pass through the positioning angle steels and be placed in their required positions. The bottom of the anchor bolt is fixedly connected to the anchoring steel plate to form a whole. The positioning angle steel and the anchoring steel plate together enhance the anti-loosening effect, further improve the tensile bearing capacity, and prevent operational errors during on-site concrete pouring.

[0007] Preferably, the four positioning angle steels are fixed together by welding.

[0008] Preferably, the bottom of the anchor bolt is formed as a whole by welding an anchoring steel plate.

[0009] Preferably, the anchoring steel plate is provided with vertical stiffening ribs to further improve the column's resistance to uplift.

[0010] The beneficial effects of this utility model are: This utility model provides a quick and simple method for anchor bolt positioning that ensures the positioning accuracy and verticality of anchor bolts; by using a prefabricated device to fix the anchor bolts and then constructing the whole structure, it is beneficial to position and adjust the anchor bolt group on site, saving the construction unit a lot of manpower and time, and creating certain economic benefits.

[0016] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings:

[0017] Example: Figures 1-4 As shown, a new type of positioning anchor bolt for steel structure columns includes an anchor bolt 1, a positioning steel plate 2, an anchoring steel plate 3, and a positioning angle steel 4. The anchor bolt 1 passes through a pre-drilled positioning hole on the positioning steel plate 2 and then through a pre-drilled positioning hole on the positioning angle steel 4 to ensure its verticality. The positioning angle steel 4 is moved to the elevation position for welding and finally welded to the anchoring steel plate 3.

[0018] The number of positioning holes is determined by the number of anchor bolts. The positioning template is manufactured in the factory to ensure accurate positioning of the holes.

[0019] This invention solves three key problems in the construction of steel chimney anchor bolts:

[0020] 1. Ensure the anchor bolts are accurately positioned and their verticality is guaranteed;

[0021] 2. Quick positioning reduces the workload required for anchor bolt positioning;

[0022] 3. Improved the overall stability of anchor bolts and reduced deviations caused by on-site pouring.

[0023] The embodiments described above are merely preferred solutions of this utility model and are not intended to limit this utility model in any way. Other variations and modifications are possible without departing from the technical solutions described in the claims.
