Description

Technical Field

[0001] The utility model relates to the technical field of building engineering construction, in particular to a device for adjusting the elevation of an iron tower foundation bolt. Background Art

[0002] New energy projects have been the general trend in recent years and are part of the green energy construction encouraged by the state. In new energy power generation construction projects, various power generation units will gather their own electricity and transmit it to the substation, or the substation will send it to the power grid after the electricity is gathered. From an economic perspective, this is inseparable from the construction of towers. The number of towers is also doubling. How to ensure the quality of tower installation requires starting from the basics.

[0003] During the installation of the tower, it was found that the height of the anchor bolts was not easy to control and the exposed length could not be uniform. In addition, during the construction process, when the concrete was poured to the ground, the anchor bolts were installed. At this time, the anchor bolts were covered with a pile casing template for slow-setting soil pouring. Due to the slump and initial setting characteristics of the concrete, the anchor bolts were not stable enough during the early pre-embedded installation, and they were not adjusted during the late pre-embedded installation. It was easy to damage the spacing and relative size of the grouped anchor bolts during the hammering process, resulting in inconsistent heights during the later installation of the tower, which greatly wasted the construction period and occupied human resources, becoming an important factor restricting the construction period. Utility Model Content

[0004] The utility model is intended to provide a tower anchor bolt elevation adjustment device to solve the problem that the anchor bolts are not stable enough during early pre-embedded installation, and are not adjusted during late pre-embedded installation, and the spacing and relative size of the grouped anchor bolts are easily destroyed during the hammering process.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a tower anchor bolt elevation adjustment device, comprising a leveling steel plate, multiple upper support parts, a lower support part, an upper adjustment support arm and a lower adjustment support arm, the leveling steel plate is provided with multiple through holes, the multiple upper support parts are symmetrically connected to the two sides of the bottom of the leveling steel plate, the multiple lower support parts are connected to the ground and vertically correspond to the multiple upper support parts respectively, the multiple upper adjustment support arms are connected to the upper support parts in groups of two, the multiple lower adjustment support arms are connected to the lower support parts in groups of two, and an adjustment component for controlling the up and down lifting of the leveling steel plate is connected between a group of upper adjustment support arms and the lower adjustment support arms.

[0006] The working principle of the utility model: when in use, align the through hole on the leveling steel plate with the anchor bolt, place the lower support part horizontally on the ground, fix the exposed length of the anchor bolt by two layers of nuts to prevent loosening when vibrating the concrete, adjust the adjustment component to make multiple upper adjustment support arms and lower adjustment support arms change, drive the leveling steel plate to move up and down to adjust the upper and lower elevations, and after the adjustment is completed, pour concrete and vibrate. The concrete passes through the through hole on the leveling steel plate and enters the pile casing template. When the base top elevation is reached, the adjustment component is controlled to adjust the anchor bolt elevation to the final state and lock it. When the concrete is initially solidified, the double-layer nuts can be removed and the device can be removed for final maintenance.

[0007] The beneficial effects of the utility model are as follows: 1. The structure is simple, the finished product device is easy to manufacture and portable; 2. It can be directly dismantled in a short time after use, which does not affect the quality of the finished product and can continue to be used; 3. By using this device, the elevation of the anchor bolts can be quickly adjusted to ensure quality.

[0008] Furthermore, the adjustment assembly includes a threaded column and a plurality of connection blocks, wherein the connection blocks are connected between an upper adjustment support arm and a lower adjustment support arm, the plurality of connection blocks are located on the same horizontal line, the threaded column is connected between the plurality of connection blocks and the threaded column passes through the connection blocks. By setting the threaded column, the upper adjustment support arm and the lower adjustment support arm can be driven to change their displacement by rotating the threaded column, thereby driving the adjustment steel plate to move up and down.

[0009] Furthermore, one end of the threaded column is connected with a screwing ring. The threaded column can be screwed more easily by the provision of the screwing ring.

[0010] Furthermore, the leveling steel plate is of a "U" shape, and through holes are provided on opposite sides of the leveling steel plate, and the upper support portion is located on the opposite side of the leveling steel plate away from the through holes. By limiting the shape of the leveling steel plate, the concrete pouring can start from the center of the hole pile casing template, making the concrete pouring more uniform.

[0011] Furthermore, the upper support portion and the lower support portion are double-pin couplings.

[0012] Furthermore, the length of the leveling steel plate is longer than the diameter of the pile casing template. By setting the leveling steel plate longer than the diameter of the pile casing template, the pile casing template will not be touched during the disassembly process of the device, which will affect the final curing process of the concrete.
