Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel structure column anchor bolt pre-embedding technology, specifically a steel column anchor bolt pre-embedding positioning device. Background Technology
[0002] With the increasing prevalence of steel structures, steel columns are typically installed and fixed using anchor bolts at the column base. Traditionally, anchor bolt positioning during on-site construction involves fabricating positioning steel plates based on the bolt specifications and spacing. However, anchor bolt types and spacing often differ between projects, and positioning steel plates are generally not reusable. Even within the same project, multiple positioning steel plates may be required, leading to resource waste. Therefore, this paper proposes a pre-embedded positioning device for steel column anchor bolts, which can be adjusted for different anchor bolt types and spacings, enabling reuse. Utility Model Content
[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a steel column anchor bolt pre-embedded positioning device, which can effectively solve the problems in the background art.
[0004] To achieve the above objectives, this utility model discloses a pre-embedded positioning device for steel column anchor bolts. The technical solution adopted includes a main structure. The main structure includes an edge rod, on which an adjustment structure is slidably connected. The adjustment structure includes a transverse adjustment rod and a longitudinal adjustment rod. The transverse adjustment rod is located below the longitudinal adjustment rod. A positioning plate is slidably connected to the transverse and longitudinal adjustment rods. Transverse adjustment is achieved by sliding the transverse adjustment rod, and longitudinal adjustment is achieved by sliding the longitudinal adjustment rod.
[0005] As a preferred embodiment of this utility model, a first adjustment hole is provided on the edge rod, and a second adjustment hole is provided on the adjustment structure. The first adjustment hole is used to realize the sliding of the horizontal adjustment rod and the vertical adjustment rod, and the second adjustment hole is used to realize the sliding of the positioning plate.
[0006] As a preferred embodiment of this utility model, the horizontal adjusting rod is provided with support plates at both ends, and through holes are opened on the support plates. Bolts are placed inside the through holes, and the bolts connect the support plates and the edge rods. The horizontal adjusting rod is fixed by tightening or loosening the bolts.
[0007] As a preferred technical solution of this utility model, the longitudinal adjusting rod is provided with L-shaped support plates on both sides. The L-shaped support plate includes a first end and a second end. The first end is in a vertical state and connected to the longitudinal adjusting rod, and the second end is in a horizontal state and fits against the edge rod. The second end has a through hole on its surface, and the through hole contains a bolt. The bolt connects the L-shaped support plate and the edge rod. The L-shaped support plate creates a certain distance between the transverse adjusting rod and the longitudinal adjusting rod to prevent interference.
[0008] As a preferred embodiment of this utility model, a positioning plate is slidably connected inside the second adjusting hole. The positioning plate is a Z-shaped plate. One end of the positioning plate is connected to the transverse adjusting rod by the bolt. The height of the positioning plate is less than the distance between the transverse adjusting rod and the longitudinal adjusting rod, so that the positioning plate can move between the distance between the transverse adjusting rod and the longitudinal adjusting rod. An installation hole is opened at the other end of the positioning plate. The installation hole is used to install anchor bolts and realize the positioning of the anchor bolts. When installing anchor bolts of different specifications, it is only necessary to replace the positioning plate with a different hole diameter.
[0009] Compared with the prior art, the beneficial effects of this utility model are: this utility model realizes the adjustment of the anchor bolt spacing through the relative sliding of the horizontal adjusting rod, the vertical adjusting rod and the positioning plate, and can be reused multiple times. When installing anchor bolts of different specifications, only the positioning plate with different hole diameters needs to be replaced. Attached Figure Description

The technical solution adopted includes a main structure 1, which includes an edge rod 101. An adjustment structure 2 is slidably connected to the edge rod 101. A first adjustment hole 102 is opened on the edge rod 101. The adjustment structure 2 includes a transverse adjustment rod 201 and a longitudinal adjustment rod 202. A second adjustment hole 203 is opened on the surface of the transverse adjustment rod 201 and the longitudinal adjustment rod 202. The transverse adjustment rod 201 is located below the longitudinal adjustment rod 202. Support plates 2011 are provided at both ends of the transverse adjustment rod 201. Through holes are opened on the support plates 2011. Bolts 3 are placed inside the through holes, and the bolts 3 connect the support plates 2011 and the edge rod 101.
