Description

Technical Field

[0001] This utility model relates to the technical field of anti-buoyancy anchor construction, and in particular to an anchor reinforcement cage hoisting and positioning tool. Background Technology

[0002] Anti-buoyancy anchors are a type of anti-buoyancy measure for underground structures in building engineering. Anti-buoyancy anchors are structural components installed to resist the upward displacement of structures above them. Their stress direction is related to the level and changes in groundwater, and is opposite to that of compression piles.

[0003] Anti-buoyancy anchors are constructed by lowering a steel cage into the borehole after drilling, followed by pouring concrete into the borehole. Ensuring the elevation of the steel cage is crucial for controlling the top elevation of the anti-buoyancy anchor. Currently, the common technique involves placing a leveling rod on the top of the steel reinforcement cage just before it is in place, and then repeatedly measuring with a level. However, this method, where the leveling rod is placed on the top of the steel reinforcement cage, makes it difficult to control its levelness and easily leads to measurement errors. Utility Model Content

[0029] like Figures 1-3 As shown, this utility model discloses a hoisting and positioning tool for anchor rod rebar cages, including a vertical component 1, a connecting steel pipe 2, an upper limit component 3, a lower limit component 4, and a scale 5.

[0030] In this embodiment, the vertical component 1 is made of hollow steel pipe, and the pipe diameter is determined according to the size of the anchor rod cage 6.

[0031] The connecting steel pipe 2 is used to be sleeved on the outside of the vertical member 1. When in use, the connecting steel pipe 2 is inserted into the anchor rod reinforcement cage 6, and the connecting steel pipe 2 is welded and fixed to the reinforcement of the anchor rod reinforcement cage 6 at a position 1.0m away from the top of the anchor rod reinforcement cage 6.

[0032] The upper limit stop 3 is disposed on the vertical member 1 and abuts against the top end of the connecting steel pipe 2, and is used to limit the length of the vertical member 1 inserted into the connecting steel pipe 2. In this embodiment, the upper limit stop 3 is a rigid outward protruding structure fixedly installed on the vertical member 1. The rigid outward protruding structure is a fixing rod, a fixing bolt, or a protrusion. When the upper limit stop 3 is a fixing rod or a fixing bolt, an installation hole is opened on the vertical member 1 that penetrates the vertical member 1 along its diameter direction. The fixing rod or fixing bolt is fixedly installed in the installation hole, and the two ends extend symmetrically out of the installation hole to abut against the connecting steel pipe 2. When the upper limit stop 3 is a rigid outward protruding structure, the protrusion is arranged at intervals or continuously on the outer circumferential surface of the vertical member 1 along the circumferential direction.

[0033] A mounting groove 7 is formed at the lower end of the vertical member 1 along its diameter. The lower limiting member 4 includes a steel plate 4.1, a spring 4.2, and a hinge shaft 4.3. The steel plates 4.1 are arranged in pairs and symmetrically about the axis of the vertical member 1 within the mounting groove 7. The lower ends of the two steel plates 4.1 are hinged to the vertical member 1 via the hinge shaft 4.3. The spring 4.2 is located at the upper end of the steel plates 4.1 and fixedly connected between the two steel plates 4.1, used to drive the steel plates 4.1 out of the mounting groove 7. When the vertical member 1 is inserted into the connecting steel pipe 2, the steel plates 4.1 are pressed into the mounting groove 7 under the action of the connecting steel pipe 2, thereby inserting the vertical member 1 into the connecting steel pipe 2. After the lower limiting member 4 passes through the connecting steel pipe 2, the steel plates 4.1 extend out of the mounting groove 7 under the action of the spring 4.2 and abut against the lower end of the connecting steel pipe 2.

[0034] The scale 5 is set on the outer surface of the vertical member 1 along the length direction of the vertical member 1, and the scale 5 is located above the upper limit member 3, and is used as a ruler to measure the installation position of the anchor rod cage 6.

[0035] In addition, a steel wire rope 8 is connected to the upper end of the vertical component 1 for connection with equipment such as a winch.

[0036] The usage method is as follows:

[0037] Weld the connecting steel pipe 2 at a distance of 61.0m from the anchor rod cage, and weld the connecting steel pipe 2 to all the reinforcing bars. Insert the vertical component 1 into the connecting steel pipe 2, and make the upper limit component 3 and the lower limit component 4 abut against the connecting steel pipe 2. Use a winch to lift the anchor rod cage 6 through the vertical component 1, insert the anchor rod cage 6 into the borehole, press the anchor rod cage 6 down into the borehole, and observe the reading of the scale ruler 5 with a level. Control the depth of the anchor rod cage 6 according to the reading of the scale ruler 5. Alternatively, the elevation of the pile hole can be measured in advance, and the anchor rod cage 6 can be pressed down directly to the position calculated by the scale ruler 5. After installation, press the steel plate 4.1 into the installation groove 7, and pull the vertical component 1 out of the connecting steel pipe 2.

[0038] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
