Abstract
Description
Technical Field
[0001] This utility model relates to the field of building steel structure foundation engineering technology, specifically a novel column base anchor bolt fixing bracket. Background Technology
[0002] Column anchor bolts are key force-transfer components between the steel structure and the concrete foundation of a building. Their core function is to effectively transfer the vertical load, horizontal load, and seismic action of the superstructure to the foundation, and then distribute them to the ground. They are a core foundational component that ensures the overall stability, overturning resistance, and durability of the building structure.
[0003] Traditional supports often use a single angle steel frame or steel bar binding for fixation. Based on years of engineering practice, during concrete pouring and vibration or after concrete pouring, the supports are prone to horizontal or vertical displacement, which leads to the need to enlarge the holes in the column base plate during steel column installation, thus affecting the subsequent construction work. Therefore, those skilled in the art have provided a new type of column base anchor bolt fixing support to solve the problems mentioned in the background art. Utility Model Content
[0004] The purpose of this utility model is to provide a novel column anchor bolt fixing bracket to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: A novel column base anchor bolt fixing bracket includes a positioning steel plate, a connector, and a column base anchor bolt. The positioning steel plate has a plurality of first connecting holes and second connecting holes arranged in an array. The connector is provided with positioning holes and mounting holes. The positioning holes are adapted to the column base anchor bolts, and the mounting holes are detachably connected to the first connecting holes or the second connecting holes on the positioning steel plate through fasteners.
[0006] As a further improvement of this utility model, the positioning steel plate is made of Q235B steel plate with a thickness of 10-16mm, and its size is designed to be adapted to the arrangement range of the column base anchor bolts.
[0007] As a further improvement of this utility model: the diameter of the first connecting hole and the second connecting hole is 1-2mm larger than the outer diameter of the matching fastener, and the hole wall is provided with anti-slip texture.
[0008] As a further improvement of this utility model, the connector is a cuboid structure forged from alloy steel, with a length of 200-300mm, a width of 100-120mm, a height of 50-80mm, and a thickness of 4-8mm.
[0009] As a further improvement of this utility model: the positioning hole matches the external thread of the column anchor bolt, and the depth of the positioning hole is not less than 5 times the diameter of the column anchor bolt.
[0010] As a further improvement of this utility model: the mounting holes are provided in two sets and symmetrically distributed on both sides of the positioning hole, and the axis of the mounting holes is perpendicular to the axis of the positioning hole.
[0011] As a further improvement of this utility model, the column anchor bolt is a high-strength bolt with a hot-dip galvanized anti-corrosion layer on its surface, the thickness of which is not less than 80μm.
[0012] Compared with the prior art, the beneficial effects of this utility model are: This novel column base anchor bolt fixing bracket, through the coordinated design of positioning steel plates, connectors, and column base anchor bolts, features an array of connected holes that can flexibly adapt to different anchor bolt layout requirements. The detachable connection simplifies installation and maintenance. The use of Q235B steel plates and alloy steel, combined with anti-slip textured hole walls, sufficiently deep threaded positioning holes, and a hot-dip galvanized anti-corrosion layer, ensures structural strength and connection stability while enhancing corrosion resistance and durability, extending service life. The bracket effectively resists the external forces during concrete pouring and vibration, preventing horizontal or vertical displacement of the anchor bolts, significantly improving installation positioning accuracy, eliminating the need for subsequent hole enlargement work during steel column installation, reducing construction workload and shortening the cycle, while simultaneously ensuring the overall stability and safety of the building structure.

[0015] Please see Figures 1-5In this embodiment of the utility model, a novel column base anchor bolt fixing bracket includes a positioning steel plate, a connector, and a column base anchor bolt. The positioning steel plate has a plurality of first connecting holes and second connecting holes, which are arranged in an array. The connector is provided with positioning holes and mounting holes. The positioning holes are adapted to the column base anchor bolts, and the mounting holes are detachably connected to the first or second connecting holes on the positioning steel plate through fasteners. This bracket has a simple structure, wide adaptability, and is suitable for various building steel structure foundation projects, and has good prospects for promotion.
[0016] The positioning steel plate is made of Q235B steel plate with a thickness of 10-16mm. Its size is designed to be adapted to the arrangement range of the column base anchor bolts. The diameter of the first and second connecting holes is 1-2mm larger than the outer diameter of the matching fasteners, and the hole walls are provided with anti-slip textures. The connector is a cuboid structure, forged from alloy steel, with a length of 200-300mm, a width of 100-120mm, a height of 50-80mm, and a thickness of 4-8mm. This makes the positioning steel plate and connector stronger, thereby preventing deformation of the equipment during use.
[0017] The positioning hole matches the external thread of the column base anchor bolt, and the depth of the positioning hole is not less than 5 times the diameter of the column base anchor bolt. Two sets of installation holes are provided and symmetrically distributed on both sides of the positioning hole. The axis of the installation hole is perpendicular to the axis of the positioning hole. The column base anchor bolt is a high-strength bolt with a hot-dip galvanized anti-corrosion layer on its surface. The thickness of the anti-corrosion layer is not less than 80μm, which effectively resists the influence of external forces during concrete pouring and vibration, avoids horizontal or vertical displacement of the anchor bolt, greatly improves the installation positioning accuracy, eliminates the need for subsequent hole enlargement work for steel column installation, reduces construction workload, shortens the cycle, and ensures the overall stability and safety of the building structure.
[0018] The working principle of this utility model is as follows: In the early stage of construction, according to the layout range of column foot anchor bolts, a Q235B positioning steel plate with a suitable size and a thickness of 10-16mm is selected and fixed in the preset position of the concrete foundation to provide a stable support base for the overall support. A rectangular connector forged from alloy steel is selected. A high-strength anchor bolt with a hot-dip galvanized anti-corrosion layer thickness of not less than 80μm is screwed into the positioning hole on the connector through external thread. The depth of the positioning hole is not less than 5 times the diameter of the anchor bolt to ensure a stable connection between the two. Based on the anchor bolt design position, use the two sets of mounting holes symmetrically distributed on both sides of the positioning hole on the connector to align the connector with the first or second connecting hole corresponding to the array of the positioning steel plate. Since the diameter of the connecting hole is 1-2mm larger than the outer diameter of the matching fastener, positioning can be completed quickly. Then, the fastener is used to lock it in place, and the axis of the mounting hole is perpendicular to the axis of the positioning hole.
[0019] During concrete pouring and vibration, the positioning steel plate, the bidirectional fixing of the connector, and the structural strength of each component effectively resist external forces and prevent the column base anchor bolts from shifting horizontally or vertically. After the concrete has solidified, the steel column base plate can be installed and fixed through the column base anchor bolts.

Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
