Description

Technical Field

[0001] This invention relates to the field of anchor bolt construction technology, specifically to an anti-deviation synchronous limiting and elevation adjustment device for anchor bolt assembly pouring. Background Technology In construction projects such as power transmission line tower foundations, communication cable poles, and large equipment foundations, anchor bolts are crucial embedded components connecting the superstructure to the concrete foundation. The embedding accuracy of anchor bolts directly affects the smooth installation of subsequent equipment and the safety and stability of the structure. Traditional anchor bolt construction methods typically involve drilling positioning holes in the formwork, inserting the anchor bolts, and securing them by temporary welding or binding before pouring concrete.

[0002] However, conventional construction methods still have the following problems: 1. During the concrete pouring process, the impact force of the concrete and the vibration of the vibrator can easily cause the anchor bolts to shift or tilt, resulting in deviations in the pre-embedded positions. This can lead to bolt hole deviations during the later equipment installation, requiring hole enlargement or re-installation of reinforcement bars, which seriously affects the construction period and quality.

[0003] 2. The top elevations of multiple anchor bolts need to be kept on the same horizontal plane. Traditional methods rely on manual stringing or leveling instruments to measure and adjust them one by one, which is inefficient and has large errors, making it difficult to achieve synchronous and precise leveling of multiple bolts. Summary of the Invention

[0004] To address the technical problems existing in the background art, the present invention provides a synchronous limiting and elevation adjustment device for anti-deviation of anchor bolt groups during casting. Through a double-layer adjustable structure, it achieves precise positioning and elevation control of anchor bolts, effectively preventing deviation during the casting process. It is also easy to assemble and disassemble and has strong versatility.

[0005] The technical solution adopted by this invention is: A synchronous limiting and elevation adjustment device for preventing deviation during anchor bolt assembly pouring, fixedly installed on the formwork, comprising: A lower hinge seat is fixedly installed on the template, and an orchid bolt is hinged inside the lower hinge seat, the orchid bolt extending upward; a fixing plate is hinged to the upper end of the orchid bolt above the template, and a base plate for supporting the anchor bolt is installed directly below the fixing plate; a lifting bolt is installed between the base plate and the fixing plate; a through hole is provided on the fixing plate for the anchor bolt to pass through, and the threaded end of the anchor bolt extends upward and is screwed with an adjusting nut, the lower end of the adjusting nut abutting against the upper end of the fixing plate.

[0006] Furthermore, a fixing bolt is installed through and fixed on the template. The threaded end of the fixing bolt extends outward and is screwed with a lower fixing nut. The lower hinge seat is sleeved on the threaded end of the fixing bolt, and its two ends abut against the outer wall of the template and the lower fixing nut, respectively.

[0007] Furthermore, the fixing plate is configured as a rectangular first fixing plate, and the four corners of the first fixing plate are provided with a first upper hinge seat that is hinged to the upper end of the orchid bolt; the first fixing plate is provided with a plurality of first through holes distributed in a circular array, and a plurality of first through holes distributed in a circular array are provided on the outer ring of the first through holes.

[0008] Furthermore, a first lifting bolt is inserted into the first through hole, and a first through hole seat protruding upward is provided on the surface of the first fixing plate at the edge of the first through hole. A lifting nut is screwed onto the first lifting bolt, and the lower end of the lifting nut abuts against the upper end of the first through hole seat.

[0009] Furthermore, the base plate is a "well" shaped first base plate, with a central first through groove, a downwardly extending first sleeve seat, and a first screw hole on the outer ring of the first sleeve seat; the first sleeve seat is located directly below the first through hole, and the anchor bolt is inserted into the first through hole and the first sleeve seat; the first screw hole is located directly below the first through hole, and the lower end of the first lifting bolt is screwed into the first screw hole.

[0010] Furthermore, the fixing plate is a rectangular second fixing plate, and the four corners of the second fixing plate are provided with second upper hinge seats that are hinged to the upper end of the orchid bolt; the second fixing plate is provided with a plurality of second through holes distributed in a rectangular array, and a plurality of second through holes distributed in a circular array on the outer ring of the second through holes.

[0011] Furthermore, a second lifting bolt is inserted into the second through hole, and a second through hole seat protruding upward is provided on the surface of the second fixing plate at the edge of the second through hole. A lifting nut is screwed onto the second lifting bolt, and the lower end of the lifting nut abuts against the upper end of the second through hole seat.

[0012] Furthermore, the base plate is a second base plate in the shape of "╋". The second base plate has a central second through groove, a second sleeve seat extending downward, and a second screw hole on the outer ring of the second sleeve seat. The second sleeve seat is located directly below the second through hole, and anchor bolts are inserted into the second through hole and the second sleeve seat. The second screw hole is located directly below the second through hole, and the lower end of the second lifting bolt is screwed into the second screw hole.

[0013] Furthermore, the length of the orchid bolt is adjustable, which is used to adjust the levelness of the fixing plate.

[0014] Furthermore, the height adjustment nut is used to adjust the exposed length of the threaded end of the anchor bolt.

[0015] The beneficial effects of the present invention on the anti-deviation synchronous limiting and elevation adjustment device for anchor bolt group casting are as follows: 1. A rigid frame is formed by the fixing plate, base plate, and lifting bolts. The upper end of the anchor bolts is restrained in the through hole of the fixing plate, and the lower end is restrained in the sleeve seat of the base plate, forming a double restraint. When pouring concrete, the anchor bolts are firmly fixed and will not shift or tilt due to concrete impact or vibration.

[0016] 2. By rotating the height adjustment nut, the exposed length of the threaded end of each anchor bolt can be precisely adjusted; at the same time, the height adjustment nuts of all anchor bolts are based on the upper plane of the fixing plate, realizing synchronous and unified control of the elevation of multiple bolts, avoiding the tediousness and error of measuring each one individually.

[0017] 3. Two implementation methods are provided, which are applicable to circular array layouts for cable poles and rectangular array layouts for cable towers, respectively, improving versatility and adaptability. Attached Figure Description
