Description

Technical Field

[0001] This utility model relates to the technical field of flatness testing equipment, and more specifically, to a flatness testing equipment for building formwork. Background Technology

[0002] Formwork is a temporary structure used to support and shape concrete or other building materials until they harden and reach sufficient strength. Inspecting the flatness of formwork is a crucial step in ensuring the quality of concrete structures. In actual construction, for formwork that is parallel vertically, technicians typically first place a laser level in a horizontal position and emit a laser line. Then, using long calipers, they sequentially align the four corners and near-center of each formwork piece, recording the data projected onto the calipers by the laser level to measure and analyze the flatness.

[0003] However, during this measurement process, when the technician holds the calipers and aligns them with the building formwork, the weight of the calipers and their long length can cause the center of gravity to shift, which can easily lead to errors and adversely affect the flatness test results of the building formwork. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides a building formwork flatness testing device to solve the problem that when measuring the flatness of building formwork, the technician holding the caliper is prone to deviation of the center of gravity due to the weight and length of the caliper, which will cause errors and affect the test results.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a building formwork flatness testing device, comprising...

[0006] A base plate, on the top of which a flat building formwork frame is bolted, and a laser level is placed on the top of the base plate;

[0007] A caliper bracket assembly includes a supporting column, a movable column, and a horizontal moving mechanism. Two electric push rods are provided on both sides of the supporting column. The top ends of the two electric push rods are fixedly installed on the lower surfaces of the top sides of the movable column. The outer surface of the bottom end of the movable column is slidably installed on the inner surface of the middle part of the supporting column. The surface of the horizontal moving mechanism is fixedly installed on the upper surface of the movable column.

[0008] The caliper bracket assembly further includes a rotating base mechanism and a fastening mechanism. The rotating base mechanism is located at the bottom of the supporting column, and the fastening mechanism is fixedly installed on the side of the end of the horizontal moving mechanism, with a measuring caliper detachably installed in the middle.

[0009] The horizontal moving mechanism includes a double-sided rack plate, two gears, and a motor. U-shaped plates are symmetrically slidably mounted on the outer edges of both sides of the double-sided rack plate. The bottom ends of the two U-shaped plates are fixedly mounted to the upper surface of the movable column. Two gears are arranged in the middle of the two U-shaped plates near the double-sided rack plate. The two gears mesh with the two sides of the double-sided rack plate. A shaft is fixedly sleeved in the middle of each of the two gears. A transmission mechanism is sleeved on the top of the two shafts. The outer surface of the motor is fixedly mounted to the inner surface of the top of the motor, and the output end is fixedly sleeved to one of the shafts.

[0010] The rotating base mechanism includes a counterweight, a connecting rod, and a spring. A rotating seat is rotatably mounted on the inner surface of the middle part of the counterweight. The upper surface of the middle part of the rotating seat is bolted to the bottom of the supporting column and fixedly mounted to the bottom ends of the two electric push rods. A gear is provided inside the counterweight through a fixedly mounted connecting rod at the middle of the bottom of the rotating seat. The outer surface of the bottom end of the connecting rod is rotatably mounted to the middle of the counterweight. One end of the spring is fixedly connected to the inner wall of the counterweight, and the other end is fixedly connected to a protruding post. The protruding post abuts against the surface of the gear.

[0011] The fastening mechanism includes a hollow square plate and a bolt. The side of the hollow square plate is fixedly installed on the surface of the side end of the double-sided rack plate. The outer surface of the bolt is threadedly connected to the middle of the side of the hollow square plate away from the double-sided rack plate, and a push plate is rotatably installed at the end. The outer surface of the push plate is slidably installed on the inner wall of the hollow square plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In the above scheme, by setting up a caliper bracket assembly, when checking the flatness of the planar building formwork frame, the laser level and the caliper bracket assembly can be placed in appropriate positions in sequence. Then, by passing the measuring caliper through the interior of the hollow square plate, the push plate is rotated so that the connected push plate abuts against the side edge of the measuring caliper along the hollow square plate, fixing it inside the hollow square plate. Afterwards, the technician can control the motor to start, and the shaft connected to the motor output end drives the sleeved gear two to rotate. The gear two sleeved between the two shafts connected by the transmission mechanism will rotate synchronously, causing the meshing double-sided rack plate to move along the two... The surface of the U-shaped plate fixed to the top of the movable column slides, driving the fastening mechanism and measuring caliper installed at the end to adjust to the appropriate position. Then, the supporting column is controlled to extend, driving the connected movable column to slide upward along the inner wall of the supporting column, so that the horizontal moving mechanism and other structures at the top move upward synchronously until the surface of the top of the measuring caliper can be in contact with the bottom surface of the flat building formwork frame. At this time, the position data of the laser level projected on the bottom of the measuring caliper is recorded. In this way, by using the caliper bracket assembly to keep the measuring caliper stable and in contact during the measurement process, the measurement error is reduced and the accuracy of flatness detection is improved.

[0014] In the above solution, by setting up a rotating base mechanism and other structures, during the measurement process, the caliper bracket assembly is placed below the middle of the flat building formwork frame. The technician can drive the rotating seat to rotate along the inner wall of the counterweight seat by supporting the column. The connecting rod fixed to the rotating seat rotates along the inner wall of the bottom middle of the counterweight seat, and the gear one sleeved on its outside rotates inside the counterweight seat. During the rotation of gear one, the external force will squeeze the protrusion to slide towards the spring and squeeze the spring. After the external force disappears, the elastic restoring effect of the spring itself will push the protrusion to insert into the gap of gear one, thereby limiting the rotation of the rotating seat and improving the stability of use. By using the rotation of the rotating base mechanism, the lifting of the electric push rod, and the translation of the horizontal movement mechanism, multiple measurements of the flat building formwork frame can be completed in one position, so as to reduce the error caused by movement and improve the convenience of use.

[0022] As attached Figure 1 To be continued Figure 4 An embodiment of this utility model provides a building formwork flatness testing device, including...

[0024] The caliper bracket assembly 4 includes a supporting column 41, a movable column 43, and a horizontal moving mechanism 44. Two electric push rods 42 are provided on both sides of the supporting column 41. The top ends of the two electric push rods 42 are fixedly installed on the lower surfaces of the top two sides of the movable column 43. The outer surface of the bottom end of the movable column 43 is slidably installed on the inner surface of the middle part of the supporting column 41. The surface of the horizontal moving mechanism 44 is fixedly installed on the upper surface of the movable column 43.

[0025] The caliper bracket assembly 4 also includes a rotating base mechanism 40 and a fastening mechanism 45. The rotating base mechanism 40 is located at the bottom of the supporting column 41, and the fastening mechanism 45 is fixedly installed on the side of the end of the horizontal moving mechanism 44, and a measuring caliper 5 is detachably installed in the middle.

[0026] The horizontal moving mechanism 44 includes a double-sided rack plate 440, a second gear 442, and a motor 443. U-shaped plates 441 are symmetrically slidably mounted on the outer edges of both sides of the double-sided rack plate 440. The bottom ends of the two U-shaped plates 441 are fixedly mounted to the upper surface of the movable column 43. Two second gears 442 are provided near the middle of the two U-shaped plates 441, close to the double-sided rack plate 440. The two second gears 442 mesh with the two sides of the double-sided rack plate 440. A shaft is fixedly sleeved in the middle of each of the two second gears 442. A transmission mechanism 444 is sleeved on the top of the two shafts. The outer surface of the motor 443 is fixedly mounted to the inner surface of the top of the motor 443, and the output end is fixedly sleeved to a shaft.

[0027] The rotating base mechanism 40 includes a counterweight 400, a connecting rod 402, and a spring 404. A rotating seat 401 is rotatably mounted on the inner surface of the middle part of the counterweight 400. The upper surface of the middle part of the rotating seat 401 is bolted to the bottom of the supporting column 41 and fixedly mounted to the bottom ends of two electric push rods 42. A gear 403 is provided inside the counterweight 400 through the fixedly mounted connecting rod 402 at the middle of the bottom of the rotating seat 401. The outer surface of the bottom end of the connecting rod 402 is rotatably mounted to the middle of the counterweight 400. One end of the spring 404 is fixedly connected to the inner wall of the counterweight 400, and the other end is fixedly connected to a protrusion 405. The protrusion 405 abuts against the surface of the gear 403.

[0028] By setting up a rotating base mechanism 40, during the measurement process, the caliper bracket assembly 4 is placed below the middle of the flat building formwork frame 2. The technician can drive the rotating seat 401 to rotate along the inner wall of the counterweight seat 400 by supporting the column 41. The connecting rod 402, which is fixed to the rotating seat 401, rotates along the inner wall of the bottom middle of the counterweight seat 400. The gear 403, which is sleeved on the outside, rotates inside the counterweight seat 400. During the rotation of the gear 403, the external force will squeeze the protrusion 405 to slide towards the spring 404 and squeeze the spring 404. After the external force disappears, the elastic restoring effect of the spring 404 will push the protrusion 405 into the gap of the gear 403, thereby limiting the rotation of the rotating seat 401 and improving the stability of use. By using the rotation of the rotating base mechanism 40, the lifting of the electric push rod 42, and the translation of the horizontal moving mechanism 44, multiple measurements of the flat building formwork frame 2 can be completed in one position, so as to reduce the error caused by movement and improve the convenience of use.

[0030] The working process of this utility model is as follows:

[0031] When inspecting the flatness of the planar building formwork frame 2, the laser level 3 and caliper bracket assembly 4 can be placed in appropriate positions in sequence. Then, the measuring caliper 5 is passed through the interior of the hollow square plate 450. The push plate 452 is rotated so that the connected push plate 452 abuts against the side edge of the measuring caliper 5 along the hollow square plate 450, fixing it inside the hollow square plate 450. After that, the technician can control the motor 443 to start. The shaft connected to the output end of the motor 443 drives the sleeved gear 442 to rotate. The gear 442 sleeved between the two shafts connected by the transmission mechanism 444 will rotate synchronously, so that the meshing double-sided rack plate 440 moves along the two The surface of the U-shaped plate 441 fixed to the top of the movable column 43 slides, driving the fastening mechanism 45 installed at the end and the measuring caliper 5 to adjust to a suitable position. Then, the supporting column 41 is controlled to extend, driving the connected movable column 43 to slide upward along the inner wall of the supporting column 41, so that the horizontal moving mechanism 44 and other structures at the top move upward synchronously until the surface of the top of the measuring caliper 5 can be in contact with the bottom surface of the flat building formwork frame 2. At this time, the position data of the laser level 3 projected on the bottom of the measuring caliper 5 is recorded. Thus, by using the caliper bracket assembly 4 to keep the measuring caliper 5 stable and in contact during the measurement process, the measurement error is reduced and the accuracy of flatness detection is improved.
