Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of anti-anchor bolt construction, and in particular to an anti-buoyancy anchor bolt elevation control device. Background Technology
[0002] During the construction of anchor bolts, it is impossible to accurately control the hole height. When the anchor bolt is lowered after the hole is formed, its own weight will cause it to fall naturally, and the upper elevation cannot be aligned with the design elevation.
[0003] In traditional methods, controlling the anchor bolt elevation requires welding a steel bar longer than the hole diameter to the hole opening to prevent the anchor bolt from sagging. After the anchor bolt installation is complete, this welded steel bar needs to be cut off during foundation construction to avoid affecting the anchor bolt itself and subsequent work. This method undoubtedly increases labor and material costs and construction procedures, thus affecting the project schedule and contract fulfillment.
[0004] When using a laser device for elevation positioning, the external laser needs to be frequently moved, and each time it is moved, the positioning needs to be redone. Moreover, the external laser is not stable and is easily affected by the surrounding environmental factors. Utility Model Content
[0005] This invention aims to address the shortcomings of existing technologies by providing an anti-buoyancy anchor elevation control device.
[0006] To achieve the above objectives, this utility model adopts the following technical solution:
[0007] An anti-buoyancy anchor height control device includes a base frame, on which two first uprights on the front side and two second uprights on the rear side are fixed. The height of the second uprights is lower than that of the first uprights. A support rod is provided between the corresponding first and second uprights. A main rod is supported between the two support rods. A ring is provided in the middle of the front of the main rod. An adjustment plate is fixed on the side wall of the second upright. The adjustment plate has several adjustment holes. A lifting support plate is installed between the two adjustment plates. The lifting support plate has support holes at both ends, and the support holes are connected to the corresponding adjustment holes by adjustment pins. A laser emitter is fixed in the middle of the upper surface of the lifting support plate.
[0008] The lifting support plate has U-shaped plates on both ends, and the adjusting plate has front and rear slides on the side facing the lifting support plate. The two side plates of the U-shaped plates are slidably installed in the slides of the adjusting plate.
[0009] A top crossbar is connected between the tops of the two first uprights and between the tops of the two adjusting plates.
[0010] The base frame includes two parallel bottom support rods, and two connecting rods are fixed between the two bottom support rods.
[0011] The beneficial effects of this utility model are: it is easy to operate, reusable, easy to assemble, and has a high accuracy rate in controlling the elevation of anchor bolts, saving costs and shortening the construction period. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments:
[0021] An anti-buoyancy anchor elevation control device, such as Figure 1 , Figure 2 As shown, it includes a base frame 1, a first upright 2, a second upright 3, a support pole 4, a main support pole 5, a ring 6, an adjusting plate 7, an adjusting hole 8, a lifting support plate 9, a laser emitter 10, and a top crossbar 11.
[0022] The base frame 1 includes two parallel bottom support rods 101, and two connecting rods 102 are fixed between the two bottom support rods 101.
[0023] The base frame 1 is fixed with two first uprights 2 on the front side and two second uprights 3 on the rear side. The height of the second uprights 3 is lower than the height of the first uprights 2.
[0024] The first upright 2 and the second upright 3 are welded to the bottom support rod 101 at the positions where they connect with the corresponding connecting rod 102.
[0025] A support pole 4 is provided between the first upright pole 2 and the second upright pole 3, and a main pole 5 is provided between the two support poles 4. A ring 6 is provided in the middle of the front of the main pole 5.
[0026] The main lever 5 can be removed independently.
[0027] An adjustment plate 7 is fixed on the side wall of the second upright 3. Several adjustment holes 8 are opened on the adjustment plate 7. A lifting support plate 9 is installed between the two adjustment plates 7. The lifting support plate 9 has support holes at both ends and the support holes are connected to the corresponding adjustment holes 8 by adjustment pins. A laser emitter 10 is fixed at the middle position of the upper surface of the lifting support plate 9.
[0028] The lifting support plate 9 has U-shaped plates on both ends. The adjusting plate 7 has front and rear slides on the side facing the lifting support plate 9. The two side plates of the U-shaped plate are slidably installed in the slides of the adjusting plate 7.
[0029] A top crossbar 11 is connected between the tops of the two first uprights 2 and between the tops of the two adjusting plates 7.
[0030] The base frame 1, first upright 2, second upright 3, support pole 4, main support pole 5, and top crossbar 11 are all made of steel reinforcement. The lifting support plate 9 is made of 5mm thick steel plate.
[0031] The steps for using this utility model are as follows:
[0032] Preparation for implementation: Locate the known elevations near the anchor bolts in advance to make full preparations for on-site use.
[0033] Step 1: Lift the anchor bolts:
[0034] During the hole-forming process of the first worker operating the walking pile driver, the anchor rod was lifted using the pulleys and lifting wires on the top of the pile driver. Because the anchor rod was too long, a second worker was needed to complete the lifting process.
[0035] Step 2: Lower the anchor bolts and install the elevation control device:
[0036] After the hole is formed, the anchor rod can be directly lowered into the hole. When it is close to the standard elevation of the anchor rod, the first worker operates the pile driver to hold the anchor rod, and the second worker places the elevation control device on the hole.
[0037] Step 3: Control the elevation:
[0038] Adjust the height of the lifting support plate 9 so that the laser emitted by the laser emitter 10 is aligned with the measured elevation benchmark or the top of the completed anchor rod. At the same time, adjust the height of the anchor rod so that the laser on the other side is aligned with the top of the anchor rod.
[0039] Step 4: Secure the anchor bolts:
[0040] Remove the suspension line and quickly put the ring 6 of the main rod 5 into the anchor rod. Rotate the main rod 5 so that the ring 6 is tilted and fixed to the control device by friction with the anchor rod. Confirm that the top of the anchor rod is level with the design elevation.
[0041] Step 5: Remove the control device:
[0042] After the anti-buoyancy anchor rod has solidified with the surrounding cement slurry for a period of time and will not sink naturally, remove the control device.
[0043] Before use: Because the hole depth cannot be accurately controlled during drilling and the ground elevation is not consistent, the traditional method of anchor bolt elevation control will still have some errors, cannot achieve 100% accuracy, and will also increase costs and construction time.
[0044] After use: It can effectively control the elevation of the anchor bolts, achieving 100% alignment with the design elevation, while saving costs and shortening the construction period.
[0045] This invention is easy to operate, reusable, and easy to assemble. It has a high accuracy rate in controlling the elevation of anchor bolts, saving costs and shortening the construction period.
[0046] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any improvements made using the inventive concept and technical solution of the present invention, or direct application to other situations without modification, are all within the protection scope of the present invention.
