Description

Technical Field

[0001] The utility model belongs to the technical field of static load testing of pile foundations in construction engineering, and in particular relates to a telescopic static load displacement sensor mounting bracket. Background Art

[0002] The current technical specifications require that the settlement observation point of the pile foundation static load test needs to be set at a position about 20 cm below the pile top. Therefore, during the pile foundation static load test, the conventional method is to directly install the displacement sensor 20 cm below the pile top. Since the static load test is carried out directly in the construction site, after the pile foundation construction is completed, the static load detection operation is carried out after the pile top is exposed by excavation. The position of the pile top to be tested is generally lower than the ground surface. For the pile top in the basement, its position will be lower. When it rains, it is easy for water to accumulate at the position of the pile top. In the actual detection process, a pile foundation needs to be continuously tested for about 30 hours. During the test, the displacement sensor needs to measure the settlement of the pile top in real time. When it rains or there is water accumulation at the detection position, it is easy for the displacement sensor to be damaged due to flooding, which will make the test process incontinuous and affect the accuracy of the data.

[0003] In order to effectively solve the above problems, it is urgently necessary to provide a new type of sensor mounting bracket to effectively ensure that the detection process is carried out continuously and reliably and to ensure the accuracy of the detection data. Summary of the invention

[0004] In view of the problems existing in the above-mentioned prior art, the utility model provides a telescopic static load displacement sensor mounting bracket, which has a simple structure, low manufacturing cost, quick installation process, simple operation process, and strong versatility. It can transfer the detection point from below the pile top to above the pile top, and can effectively avoid the situation where the sensor is damaged by flooding due to its position being too low, and can ensure the continuity and reliability of detection, which helps to obtain more accurate detection data.

[0005] In order to achieve the above-mentioned purpose, the utility model provides a telescopic static load displacement sensor mounting bracket, comprising two vertical brackets, two adjusting screws and two pairs of adjusting nuts;

[0006] Two vertical supports are relatively distributed on the left and right sides of the pile foundation to be tested;

[0007] The vertical support comprises a fixing frame, a positioning arm, a movable column, a locking bolt and a top plate;

[0008] The fixing frame includes a vertical sleeve at the upper part and a transverse connecting beam at the lower part; a threaded hole connected to the inner cavity of the vertical sleeve is radially opened on one side of the upper part of the vertical sleeve; one end of the transverse connecting beam away from the pile foundation to be detected is fixedly connected to the lower end of the vertical sleeve, and the other end thereof extends in a direction close to the pile foundation to be detected;

[0009] The positioning arm is horizontally arranged outside the pile foundation to be detected, and the middle part is connected to the end of the transverse connecting beam close to the pile foundation to be detected, and the positioning arm is provided with through holes at both ends in the length direction;

[0010] The outer diameter of the movable column is matched with the inner diameter of the vertical sleeve, and the lower part of the movable column is vertically slidably inserted into the interior of the vertical sleeve from the upper end of the vertical sleeve;

[0011] The locking bolt is inserted into the threaded hole in the vertical sleeve through threaded matching, and abuts against the movable column to achieve the positioning of the movable column at different heights;

[0012] The top plate is horizontally fixedly connected to the upper end of the movable column;

[0013] The number of the adjusting screws is two.

[0014] Two adjusting screws are relatively distributed on the front and rear sides of the pile foundation to be tested, and the two ends of each adjusting screw pass through the two through holes on the same side of the two positioning arms respectively;

[0015] The two pairs of adjusting nuts correspond to the two adjusting screws respectively, and each pair of adjusting nuts is distributed on the outer sides of the two positioning arms and is connected to the corresponding adjusting screws through threaded matching.

[0016] As a preference, the positioning arm is a semicircular or semi-square curved arm, and its size is adapted to the outer diameter of the pile foundation to be inspected; and the adjusting screw is a short threaded rod.

[0017] Furthermore, in order to enable the positioning arm to meet the detection requirements of pile foundations with different diameters to be detected, the positioning arm is provided with multiple through holes at both ends in the length direction. By providing multiple through holes at each end in the length direction, the relative distance between the two adjusting screws can be adjusted by changing the positions of the through holes, thereby meeting the detection requirements of different pile foundation diameters to be detected.

[0018] Furthermore, in order to ensure that the positioning arm can be stably fixed to the outside of the pile foundation to be inspected and to have a longer service life, the positioning arm is made of C-shaped steel.

[0019] As a preference, the fixing frame is L-shaped, and the lower end of the vertical sleeve and the end of the transverse connecting beam away from the pile foundation to be inspected are fixedly connected vertically to each other.

[0020] Furthermore, in order to ensure good corrosion resistance and a good service life, the vertical sleeve is made of high-strength galvanized square steel pipe.

A threaded hole is opened on one side of the upper part of the vertical sleeve, and a locking bolt is inserted therein, so that the locking bolt can be used to position the different telescopic states of the movable column, thereby enabling the mounting bracket to be flexibly adjusted according to different actual working conditions, significantly improving the versatility of the mounting bracket. The lower part of the fixed frame is provided with a transverse connecting beam, and a positioning arm is connected to one end of the transverse connecting beam. In this way, the two positioning arms in the two vertical brackets can be used in conjunction with two adjusting screws to connect the fixed frame to the pile foundation to be detected, thereby achieving a reliable connection between the vertical bracket and the pile foundation to be detected, so that the top plate can move synchronously with the pile foundation to be detected, ensuring the accuracy of the detection. At the same time, since the transverse connecting beam can extend to a certain distance outside the pile foundation to be detected, the vertical sleeve and the movable column can have a certain lateral distance from the pile foundation to be detected, so that the detection sensor can be more conveniently supported, ensuring the convenience of the detection process.

[0022] The mounting bracket has a simple structure, low manufacturing cost, quick installation process, simple operation process, and strong versatility. It can transfer the detection point from below the pile top to above the pile top, which can effectively avoid the sensor being damaged by flooding due to its too low position, ensure the continuity and reliability of detection, help to obtain more accurate detection data, and provide reliable technical support for the improvement of detection technology.

[0027] like Figure 1 and Figure 2 As shown, the present invention provides a telescopic static load displacement sensor mounting bracket, comprising two vertical brackets 1, two adjusting screws 2 and two pairs of adjusting nuts 10;

[0028] Two vertical brackets 1 are relatively distributed on the left and right sides of the pile foundation to be tested;

[0031] The positioning arm 6 is horizontally arranged outside the pile foundation to be detected, and the middle part is connected to the end of the transverse connecting beam 4 close to the pile foundation to be detected, and the positioning arm 6 is provided with through holes at both ends in the length direction;

[0032] The outer diameter of the movable column 7 is matched with the inner diameter of the vertical sleeve 3, and the lower part thereof is vertically slidably inserted into the interior of the vertical sleeve 3 from the upper end of the vertical sleeve 3;

[0033] The locking bolt 9 is inserted into the threaded hole in the vertical sleeve 3 through threaded matching, and abuts against the movable column 7 to achieve the positioning of the movable column 7 at different heights;

[0034] The top plate 8 is horizontally fixedly connected to the upper end of the movable column 7;

[0035] The number of the adjusting screws 2 is two.

[0036] The two adjusting screws 2 are relatively distributed on the front and rear sides of the pile foundation to be tested, and the two ends of each adjusting screw 2 pass through the two through holes on the same side of the two positioning arms 6 respectively;

[0037] The two pairs of adjusting nuts 10 correspond to the two adjusting screws 2 respectively, and each pair of adjusting nuts 10 is distributed on the outside of the two positioning arms 6 and is connected to the corresponding adjusting screw 2 through threaded fitting.

[0038] As a preferred embodiment, in order to ensure the detection effect and at the same time, in order to make the top plate have a longer service life, the top plate 4 is a circular flat plate or a square flat plate and is made of steel plate.

[0039] As an implementation scheme, the positioning arm 6 is a straight arm, and its length is greater than the diameter of the pile foundation to be detected; the adjusting screw 2 is an extended threaded rod.

[0040] As another embodiment, the positioning arm 6 is a semicircular or semi-square curved arm, and its size is adapted to the outer diameter of the pile foundation to be inspected. When the two positioning arms 6 are combined, a circular or square closed positioning structure is formed, so as to be adapted to the pile foundation to be inspected with a circular or square cross-section; the adjusting screw 2 is a short threaded rod.

[0041] Furthermore, in order to enable the positioning arm to meet the detection requirements of pile foundations with different diameters to be detected, the positioning arm 6 is provided with multiple through holes at both ends in the length direction. By providing multiple through holes at each end in the length direction, the relative distance between the two adjusting screws can be adjusted by changing the positions of the through holes, thereby meeting the detection requirements of different pile foundation diameters to be detected.

[0042] In order to ensure that the positioning arm can be stably fixed to the outside of the pile foundation to be inspected and to have a longer service life, the positioning arm 6 is made of C-shaped steel.

[0043] As a preference, the fixing frame 5 is L-shaped, and the lower end of the vertical sleeve 3 and the end of the transverse connecting beam 4 away from the pile foundation to be inspected are vertically fixedly connected to each other.

[0044] In order to ensure good corrosion resistance and long service life, the vertical sleeve 3 is made of high-strength galvanized square steel pipe.

[0045] In the utility model, a vertical sleeve is provided on the upper part of the fixing frame, and at the same time, the lower part of the movable column is slidably inserted into the vertical sleeve, and the top plate is fixedly connected to the upper end of the movable column horizontally, so that the detection point originally located below the pile top can be cleverly transferred to the top plate at a certain distance above the pile top, so that the detection sensor can be set at a certain position above the pile top, and a protective cover can be conveniently set for the detection sensor, which can effectively avoid the situation that the detection sensor is easily damaged by water when performing detection operations on rainy days, and at the same time, it can also avoid the situation that the detection sensor is damaged by water accumulation due to its low position, thereby effectively ensuring the continuity and reliability of the detection, and at the same time, significantly improving the accuracy of the detection data. A threaded hole is opened on one side of the upper part of the vertical sleeve, and a locking bolt is inserted therein, so that the locking bolt can be used to position the different telescopic states of the movable column, thereby enabling the mounting bracket to be flexibly adjusted according to different actual working conditions, significantly improving the versatility of the mounting bracket. The lower part of the fixed frame is provided with a transverse connecting beam, and a positioning arm is connected to one end of the transverse connecting beam. In this way, the two positioning arms in the two vertical brackets can be used in conjunction with two adjusting screws to connect the fixed frame to the pile foundation to be detected, thereby achieving a reliable connection between the vertical bracket and the pile foundation to be detected, so that the top plate can move synchronously with the pile foundation to be detected, ensuring the accuracy of the detection. At the same time, since the transverse connecting beam can extend to a certain distance outside the pile foundation to be detected, the vertical sleeve and the movable column can have a certain lateral distance from the pile foundation to be detected, so that the detection sensor can be more conveniently supported, ensuring the convenience of the detection process.

[0046] The mounting bracket has a simple structure, low manufacturing cost, quick installation process, simple operation process, and strong versatility. It can transfer the detection point from below the pile top to above the pile top, which can effectively avoid the sensor being damaged by flooding due to its too low position, ensure the continuity and reliability of detection, help to obtain more accurate detection data, and provide reliable technical support for the improvement of detection technology.

[0047] During use, when the positioning arm is a straight arm, the two positioning arms are relatively and snugly arranged on the left and right sides of the pile foundation to be detected. At the same time, the positions of the through holes to be installed with the adjusting screws are determined on the front and back sides of the pile foundation to be detected. Then, the two adjusting screws are relatively and snugly arranged on the front and back sides of the pile foundation to be detected, and each adjusting screw is passed through the through holes on the two positioning arms on the same side. Next, a pair of adjusting nuts are respectively connected to the two ends of the adjusting screws, and the two positioning arms are fixedly clamped on the outside of the pile foundation to be detected by adjusting the distance between the pair of adjusting nuts. In this way, the reliable connection between the two fixing frames and the pile foundation to be detected is realized; when the positioning arm is a semicircular or semi-square curved arm, the two positioning arms are relatively buckled on the periphery of the corresponding pile foundation to be detected, and at the same time, the ends on the same side are fixed to each other using the adjusting screws, and the two positioning arms are fixed and clamped on the outside of the pile foundation to be detected using the two adjusting screws; then, the movable column with the top plate fixed at the upper end is slidably inserted into the vertical sleeve, and the movable column is positioned at a suitable height using the locking bolt, thus completing the installation process of the mounting bracket. In this way, the detection operation can be performed using the detection sensor set up above the top plate.
