Description

Technical Field

[0001] The utility model relates to the field of building engineering construction, in particular to an auxiliary positioning device for pre-buried anchor bolts in steel column installation, aiming to improve the pre-buried positioning accuracy and construction efficiency of the anchor bolts. Background Art

[0002] In steel structure construction, anchor bolts are the key load-transmitting components connecting steel columns to foundations. Their construction quality plays a crucial role in the safety and durability of the structure. Problems such as the limited space available for pre-buried anchor bolts, the densely packed reinforcement in the pre-buried caps, and the inability to secure pre-buried anchor bolts have long been difficult to resolve. During the pouring of the steel column foundation, embedded components must be pre-buried within the concrete foundation. This requires high precision in both the location and elevation of the pre-buried anchor bolts, and their heavy weight and anchored ends make adjustment difficult.

[0003] Patent application number CN202310402619.4 discloses an anchor bolt positioning system, which relates to the field of mechanical processing. The anchor bolt positioning system includes a bolt positioning mechanism for positioning the anchor bolts. The bolt positioning mechanism includes a fixed frame for positioning, within which are bolt holes for receiving the anchor bolts. A size adjustment mechanism for adjusting the length is located adjacent to the bolt positioning mechanism. The size adjustment mechanism includes a telescopic sleeve for adjusting the length, within which is a telescopic insertion rod for extending the length, which is slidably connected to the telescopic sleeve. A length positioning mechanism is located on top of the size adjustment mechanism for determining the telescopic insertion rod's retractable length.

[0004] However, the above patented technology has a complex structure and cannot solve the needs of adjusting plane position, verticality and other indicators in actual construction. Utility Model Content

[0005] The purpose of this utility model is to provide an adjustable steel column anchor bolt auxiliary positioning device to solve the problems raised in the above background technology:

[0006] (1) When it is found that the position of the anchor bolts has a large deviation, how to adjust the overall elevation of the anchor bolts to avoid wasting time due to reinstallation.

[0007] To achieve the above objectives, the present invention provides the following technical solutions:

[0008] An adjustable steel column anchor bolt auxiliary positioning device;

[0009] It includes a positioning steel plate, several anchor bolts and several positioning nuts. The several anchor bolts correspond to the several positioning nuts one by one. The several positioning nuts are fixedly connected to the positioning steel plate. The anchor bolts penetrate the positioning steel plate and cooperate with the corresponding positioning nuts. The upper end of the anchor bolt extends out of the upper area of ​​the positioning steel plate, and the lower part of the anchor bolt is in the casting area.

[0010] On the basis of the above technical solution, the present invention can also be improved as follows.

[0011] Furthermore, a bending portion is provided at the lower portion of the anchor bolt.

[0012] Furthermore, it also includes a number of bending components, which correspond one-to-one to a number of anchor bolts. The bending components include a threaded sleeve and an extension rod. The threaded sleeve and the anchor bolt are threaded together, and the starting end of the extension rod is fixedly connected to the side wall of the threaded sleeve; the ends of the extension rods of all bending components are fixed together.

[0013] Furthermore, the ends of the extension rods of all the bending components are fixedly connected via brackets.

[0014] Furthermore, it also includes several adjustment components, which include an adjusting screw and a first adjusting nut. The first adjusting nut is fixedly connected to the positioning steel plate. The adjusting screw passes through the positioning steel plate and cooperates with the corresponding first adjusting nut. The upper end of the adjusting screw extends out of the upper area of ​​the positioning steel plate, and the lower end of the adjusting screw rests on the concrete base on the lower side of the casting area.

[0015] Furthermore, the adjustment assembly also includes a second adjustment nut, which is fixedly connected to the upper end of the adjustment screw.

[0016] The adjustable steel column anchor bolt auxiliary positioning device improves the accuracy of the pre-embedded positioning of the anchor bolts (including plane position and verticality), while improving construction efficiency and simplifying the pre-embedded operation process of the anchor bolts. At the same time, during the pre-embedded process, if it is found that the position of the anchor bolts has a large deviation, the overall elevation of the anchor bolts can be adjusted with the help of the adjustment component. After the rough adjustment, detailed fine-tuning can be carried out to avoid wasting time caused by reinstallation.

[0017] This adjustable steel column anchor bolt auxiliary positioning device uses a self-made positioning steel plate to position the anchor bolts in the same base with each other and perform high-precision control. The positioning steel plate is factory-processed and manufactured to ensure the accurate size and position of the anchor bolts. At the same time, the outer periphery of the steel plate is equipped with an adjustable screw. The adjustment component can be used to adjust the elevation of the positioning steel plate to the designed elevation position, thereby achieving high-precision control of the installation elevation of the anchor bolts and effectively improving the pre-buried construction quality of the anchor bolts.

[0018] Beneficial technical effects of this adjustable steel column anchor bolt auxiliary positioning device:

[0019] (1) The position of the anchor bolts can be accurately determined to avoid displacement of the anchor bolts during concrete pouring. By positioning the bolt holes precisely machined on the steel plate, the deviation of the anchor and vertical position can be controlled within a very small range.

[0020] (2) Compared with the traditional method of measuring and positioning anchor bolts one by one, the adjustment assembly can complete the positioning and installation of multiple anchor bolts at one time. If the position of the anchor bolts is found to be deviated during the installation process, the adjustment assembly can be used to make adjustments more conveniently, greatly improving the overall construction efficiency.

[0021] (3) Effectively prevent the anchor bolts from tilting during concrete pouring. Since the adjustment assembly provides firm support and positioning for the anchor bolts, the anchor bolts can remain vertical even when there is external force during the concrete vibration process. At the same time, the adjustment assembly has a corresponding limit structure to ensure that the depth of the anchor bolts buried in the concrete meets the design requirements, avoiding the impact of insufficient or excessive burial depth on the anchor bolts' anchoring performance and equipment stability.

[0030] Example 1

[0031] See also Figures 1 to 2 .

[0032] The adjustable steel column anchor bolt auxiliary positioning device includes a positioning steel plate 100, four anchor bolts 200, four positioning nuts 300 and four sets of adjustment components.

[0033] The positioning steel plate 100 is a rectangular steel plate structure, and four anchor holes 110 and four screw holes 120 are respectively opened at the four corners of the positioning steel plate 100.

[0034] The four anchor bolts 200 correspond to four sets of positioning nuts 300 one by one. The four positioning nuts 300 are welded and fixed on the upper end surface of the positioning steel plate 100. The inner holes of the four positioning nuts 300 are respectively connected to the four anchor through-holes 110 of the positioning steel plate 100. The anchor bolts 200 pass through the positioning steel plate 100 and cooperate with the corresponding positioning nuts 300. The upper end of the anchor bolt 200 extends out of the upper side area of ​​the positioning steel plate 100. The lower part of the anchor bolt 200 is in the casting area. The lower part of the anchor bolt 200 is provided with a bending portion 210.

[0035] Four sets of adjustment components are arranged in a rectangular shape at the four corners of the positioning steel plate 100. The adjustment components include an adjustment screw 410, a first adjustment nut 420, and a second adjustment nut 430. The first adjustment nut 420 is welded to the upper end surface of the positioning steel plate 100. The inner holes of the four first adjustment nuts 420 are connected to the four screw holes 120 of the positioning steel plate 100. The adjustment screw 410 passes through the positioning steel plate 100 and cooperates with the corresponding first adjustment nut 420. The upper end of the adjustment screw 410 extends out of the upper area of ​​the positioning steel plate 100, and the lower end of the adjustment screw 410 rests on the concrete cap below the casting area. The second adjustment nut 430 is welded to the upper end of the adjustment screw 410.

[0036] During use, since the first adjusting nut 420 is welded around the positioning steel plate 100, workers can use electric tools or manually rotate the second adjusting nut 430. The second adjusting nut 430 drives the adjusting screw 410 to achieve the elevation adjustment of the positioning steel plate 100. The anchor bolt 200 passes through the anchor through-hole 110 and the positioning nut 300 for temporary fixation.
