Description

Technical Field

[0001] The invention relates to the technical field of connection and fixing construction of an inclinometer tube and a reinforcement cage in a pile foundation project, and more particularly to a device for fixing the reinforcement cage and the inclinometer tube. Background Art

[0002] During the construction of the foundation pit, the deep horizontal displacement monitoring of the supporting structure is required according to the requirements of the specification. When the supporting structure is a concrete cast-in-place pile, the inclinometer tube is installed in the steel cage, and the inclinometer is placed in the inclinometer tube to measure the displacement of the supporting structure. There are two main problems in the process of installing and tying the inclinometer tube in the steel cage: First, since the diameter of the steel cage is mostly about 1m, it is a very difficult problem to place and tie the inclinometer tube in such a small space. At present, the basic method used in China requires manual drilling into the steel cage and using iron wire or thin steel bars to tie the inclinometer tube to the bottom of the steel cage. The construction space is limited, the tying is difficult, and the long construction time is easy to cause pain to the human body. Second, most of the inclinometer tubes are currently tied to the main reinforcement at the bottom of the steel cage with iron wire or thin steel bars, and tied at least once every one meter to ensure that the inclinometer tube will not loosen. However, after the tying is completed, there is still a probability that the inclinometer tube will slide down and loosen when pouring concrete, resulting in the instability of the inclined side tube.

[0003] Therefore, how to provide a device for fixing the steel cage and the inclinometer tube is a problem that those skilled in the art need to solve urgently. Summary of the invention

[0039] See attached Figure 2 and 6 A hydraulic press 8 is coupled between the accommodating box 6 and the supporting column 1, and the hydraulic press 8 is connected to the control box 7. A hydraulic push rod 81 hydraulically connected to the hydraulic press 8 is arranged between the top end of the pushing rod 3 and the supporting column 1, and is used to drive the pushing rod 3 to swing.

[0040] The bottom of the push rod has a magnetic position, which is used to attract the buckle and push the first clamp to be inserted under the steel cage. The drill bit used by the electric drill also has a magnetic attraction effect.

[0041] The hydraulic device 8 used in the present invention has an oil tank 82 inside, and the outlet side of the oil tank is provided with a primary oil pump 83, an oil outlet pipe, a booster pump 84, a control oil valve 85, an oil supply pipeline, and an oil return pipeline and an oil return filter 86.

[0042] See attached Figure 3 The buckle 4 can be made of stainless steel, and includes a first clamping plate 41, a second clamping plate 42 and a movable clamping plate 43; a channel is formed between the first clamping plate 41 and the second clamping plate 42, and the movable clamping plate 43 is located in the channel to increase the clamping force.

[0043] Advantageously, the first clamping plate 41 is a straight plate, one end of which is thickened and provided with a first threaded hole 411, the second clamping plate 42 is an arc-shaped plate, one end of which is hinged to the first clamping plate 41, and the other end of the arc-shaped plate corresponding to the end thereof forms a flat thickened connecting surface, on which a second threaded hole 421 corresponding to the first threaded hole 411 is provided, and the movable clamping plate 43 is an arc-shaped plate, with its arc-shaped edge facing the first clamping plate 41 side, one end of which is hinged to the inner side of the second clamping plate 42, and the other end is a free end.

[0044] In the embodiment of the present invention, in order to increase the friction between the buckle, the inclinometer tube and the steel cage, a circle of thin foam plastic coated with glue is arranged inside the second clamping plate 42 and the movable clamping plate 43 of the buckle as an adhesive layer to increase the bonding force between the buckle and the inclinometer tube. A rough surface in the form of reverse thread is arranged on the top plane of the first clamping plate to increase the bite force between the buckle and the steel cage. Figure 3 The movable clamp shown in the figure is also in an open state due to the effect of gravity when the buckle is opened, so as to clamp the inclinometer tube.

[0045] Advantageously, a hook ring 44 is provided on the outer side of the second clamping plate 42 near the second threaded hole 421 .

[0046] See attached Figure 7 The connecting rod 5 is a plurality of telescopic sleeves with different diameters stacked together in sequence, the bottom telescopic sleeve is provided with the auxiliary part 51, and the top of the top telescopic sleeve is provided with a handle 52. Specifically, the auxiliary part 51 is a hook that cooperates with the hook ring 44.

[0047] The telescopic sleeve is made of stainless steel. In one embodiment of the present invention, the telescopic sleeve can be divided into six sections, each section is 25 cm long, the upper end of which is a handle with a length of 15 cm, and the lower end of which is a hook for hooking the hook ring on the buckle, thereby playing the role of lifting the second splint to open it. When not in use, the telescopic rod is placed at the second installation position of the support column and fixed by the strap 9 to make it integrated with the support column for easy storage and use.

[0048] When using the present invention, after the inclinometer tube is placed in the steel cage, the buckle is placed on the magnetic part at the bottom of the push rod, and the hook ring is hooked with the connecting rod to make the buckle in an open state. A fastener (such as a screw) is placed at the drill bit 21 in advance, and then the device is placed into the steel cage through the main reinforcement spacing from the outside of the steel cage. It should be noted that the electric drill and the push rod are placed from two adjacent spacings. The support column on the upper part of the electric drill is pulled out by hand to extend to a suitable length, and the hydraulic push rod is controlled by the hydraulic control switch to make the push rod drive the buckle close to the lateral end of the inclinometer tube. When it reaches the suitable position, the first clamp is aligned with the gap below the steel cage, and the hydraulic push rod is started to slowly insert the first clamp under the main reinforcement of the steel cage, so that the inclinometer tube passes through the channel formed by the second clamp and the movable clamp. When the first clamp has been completely passed, the second clamp is fastened, and the inclinometer tube and the main reinforcement of the steel cage are now fixed together by the clamp; the length of the support column on the upper part of the electric drill is adjusted by hand until the electric drill with the screw is aligned with and contacts the first threaded hole and the second threaded hole of the clamp, and the electric drill is started to drill the screw into the threaded hole of the clamp. At this time, the second clamp will be quickly pressed against the first clamp, and the movable clamp will also tightly wrap the inclinometer tube, and the first clamp will also bite the main reinforcement to achieve the effect of fixing the inclinometer tube.

[0049] The present invention realizes tying the inclinometer tube outside the steel cage without manually drilling into the steel cage; the fixing effect of tying the steel cage and the inclinometer tube avoids the inclinometer tube from sliding when the steel cage is lowered and concrete is poured; the device is light and easy to operate, saves manpower and has low cost. The device has fast tying speed and good effect, avoids repeated tying and saves time.
