[0019] Other advantages, objectives and features of this invention will be partly apparent from the following description, and partly understood by those skilled in the art through study and practice of this invention. Attached Figure Description

[0023] Figure 4 for Figure 1 BB section view (the two ends of the bolt horizontal positioning screw are not shown). Detailed Implementation

[0024] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0025] like Figures 1 to 4 As shown, this utility model provides a device for assembling steel structure anchor bolts 2, comprising: a reinforcing steel frame 1; a positioning steel template 4 having holes 5 for the anchor bolts 2 to pass through, the positioning steel template 4 being fixedly connected to the reinforcing steel frame 1; a bolt end positioning screw 3, detachably connected to the reinforcing steel frame 1, disposed on one side of the positioning steel template 4, for abutting against the threaded end of the anchor bolt 2; a bolt horizontal positioning screw 6, on which a pair of positioning nuts 8 are disposed, the pair of positioning nuts 8 being sleeved on the bolt horizontal positioning screw 6 in a manner that allows them to move along the bolt horizontal positioning screw 6; the bolt horizontal positioning screw 6 being detachably connected to the reinforcing steel frame 1, the pair of positioning nuts 8 and the screw portion between the pair of positioning nuts 8 together defining a space for the anchor bolts 2 to pass through.

[0026] The steel reinforcement cage 1 serves as the overall support frame, constructed from scrap steel bars welded into a grid or mesh shape. Its dimensions are determined according to the design requirements of the pre-embedded anchor bolts 2, ensuring sufficient rigidity and stability. The positioning steel template 4, cut from steel plate, is fixedly connected to the steel reinforcement cage 1. The number and spacing of its holes match the bolt holes on the column base plate, used to insert the anchor bolts 2 and define their installation positions. The bolt end positioning screw 3 is detachably connected to the steel reinforcement cage 1 and positioned on one side of the positioning steel template 4. It abuts against the threaded end of the anchor bolt 2, controlling its exposed length. The bolt horizontal positioning screw 6 is detachably connected to the steel reinforcement cage 1 and has a pair of movable positioning nuts 8. Adjusting the spacing of the pair of positioning nuts 8 ensures that the screw portion between them matches the diameter of the anchor bolt 2, thus defining the installation position of the anchor bolt 2.

[0027] The assembly device for anchor bolts 2 provided by this utility model consists of a steel reinforcement frame 1, a bolt end positioning screw 3, a positioning steel template 4, and a bolt horizontal positioning screw 6. The bolt is assembled into a whole by this device and fixed by welding with steel reinforcement to ensure that the bolt does not have displacement or dimensional deviation.

[0028] The use of this device can enhance the horizontal, vertical, and height accuracy during the installation of steel columns; it is less susceptible to damage and dimensional deviations during concrete pouring; the device itself is easy to source, disassemble, and assemble, and is highly operable; it can effectively reduce the cost of pre-embedded anchor bolts, and provide convenience for the subsequent installation of steel columns, reducing the difficulty of steel column installation and improving its installation accuracy.

[0029] In a preferred embodiment, in the device for assembling steel structure anchor bolts 2, the bolt horizontal positioning screw 6 is disposed on the other side of the positioning steel template 4.

[0030] The bolt horizontal positioning screw 6 effectively restricts the path of the anchor bolt 2 from the other side of the positioning steel template 4, further restricting the installation position of the anchor bolt 2.

[0031] In a preferred embodiment, in the device for assembling steel structure anchor bolts 2, the bolt horizontal positioning screw 6 is positioned near the anchoring end of the anchor bolt 2.

[0032] The bolt horizontal positioning screw 6, the positioning steel template 4, and the bolt end positioning screw 3 restrict the path of the anchor bolt 2 from three positions, thus limiting the installation position of the anchor bolt 2. The bolt horizontal positioning screw 6 mainly restricts the position of the anchor end of the anchor bolt 2, improving the positioning accuracy of the anchor bolt 2.

[0033] In a preferred embodiment, in the device for assembling the steel structure anchor bolts 2, the positioning steel template 4 is positioned corresponding to the threaded end of the anchor bolt 2. Specifically, the size of the hole 5 in the positioning steel template 4 matches the size of the threaded end of the anchor bolt 2.

[0034] In a preferred embodiment, in the device for assembling steel structure anchor bolts 2, both ends of the bolt end positioning screw 3 are detachably connected to the reinforcing steel frame 1 by a pair of first nuts 10.

[0035] In a preferred embodiment, in the device for assembling steel structure anchor bolts 2, both ends of the bolt horizontal positioning screw 6 are detachably connected to the reinforcing steel frame 1 via a pair of second nuts 9.

[0036] In a preferred embodiment, in the device for assembling steel structure anchor bolts 2, the positioning steel template 4 and the reinforcing steel frame 1 are connected by welding.

[0037] In a preferred embodiment, in the device for assembling steel structure anchor bolts 2, the positioning steel template 4 has multiple rows of holes 5, each row of holes includes multiple holes, each row of holes corresponds to a bolt end positioning screw and a bolt horizontal positioning screw 6, and each hole corresponds to a pair of positioning nuts 8.

[0038] Specifically, the number of holes 5 on the positioning steel template 4 matches the number of anchor bolts 2. If 6 anchor bolts 2 need to be installed, divided into two rows of 3, then the positioning steel template 4 has 2 rows of holes, with 3 holes in each row. Each row is equipped with a bolt positioning horizontal threaded rod and a bolt end positioning threaded rod 3.

[0039] The working process of the device for assembling steel structure anchor bolts provided by this utility model is as follows:

[0040] Step 1: Weld the overall frame with steel bars.

[0041] Step 2: Fabricate a positioning steel template 4 using steel plates, with the same dimensions and hole positions as the column base plate. The position, number, and spacing of the holes on the positioning steel template 4 should be consistent with the position, number, and spacing of the holes on the steel structure column base plate. Here, the column base plate is used to install the steel structure (i.e., the steel column), and the holes in the column base plate are for installing the anchor bolts 2 during the subsequent installation of the steel structure.

[0042] Step 3: Install positioning steel template 4 and weld it for reinforcement.

[0043] Step 4: Calculate the position of the bolt end positioning screw 3 by the exposed length of the thread (i.e., the threaded end) of the anchor bolt 2, and fix both ends of the bolt end positioning screw to the corresponding positions of the steel reinforcement cage 1 by the first nut 10 to restrict the threaded end of the anchor bolt 2.

[0044] Step 5: Calculate the spacing of the anchor bolts 2 based on the location of the holes in the column base plate. Adjust a pair of second nuts 9 so that the positions of a pair of positioning nuts 8 correspond to the anchor bolts 2, and ensure that the space defined by the pair of positioning nuts 8 and the threaded rod between them corresponds exactly to the holes on the positioning steel template 4, thus guaranteeing the path and installation position of the anchor bolts 2.

[0045] Step 6: Assemble the anchor bolts 2, ensuring they pass sequentially through the space between the pair of positioning nuts 8 on the bolt horizontal positioning screw 66 and the holes on the positioning steel template 4, with the threaded end abutting against the bolt end positioning screw. Double-check the position and dimensions.

[0046] Step 7: Reinforce the anchor bolts 2 by welding them to the reinforcing steel cage 1. The positioning reinforcement fixing point 7 is welded to connect the reinforcing steel cage 1 and the anchor bolts 2 into a rigid whole to prevent the anchor bolts from shifting due to vibration or impact during concrete pouring.

[0047] Step 8: After welding is completed, proceed with installation.

[0048] Step 9: Repeat steps 6 to 8 until the pre-embedded anchor bolts are installed.

[0049] This device is readily available, easy and quick to assemble, has a high turnover rate, and is convenient to operate. It replaces the traditional method of installing anchor bolts separately, has strong applicability, saves installation time, improves installation accuracy, saves anchor bolt installation time, improves the quality of steel column installation, has high safety, has a technical basis for widespread promotion, has significant economic benefits, saves labor and turnover materials, and has high social benefits.

[0050] Although embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. It can be applied to various fields suitable for this utility model. Other modifications can be readily implemented by those skilled in the art. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and examples shown and described herein.
