Description

Technical Field

[0001] This invention relates to the field of building construction angle measuring devices, and in particular to an I-beam installation angle measuring device. Background Technology

[0002] With the development of the construction industry, complex and irregularly shaped buildings with concave and convex facades, recessed floors, and staggered floors are constantly emerging. When using traditional cantilevered I-beam scaffolding for the construction of complex and irregularly shaped facades such as fourth-generation residential buildings, there are problems with the excessive length and staggered arrangement of the I-beams, which seriously affects the subsequent interior and exterior wall construction processes. To address these issues, the basket-style cantilevered scaffolding construction method has emerged, effectively solving the above problems and facilitating the smooth progress of subsequent processes.

[0003] In structures such as cantilever scaffolding and steel-concrete composite beams, it is often necessary to overlap and fix the cantilevered I-beams with the spreader beam I-beams that serve as supports. After overlapping, the relative angle between the two I-beams in the horizontal plane (i.e., the horizontal deflection angle) and in the vertical plane (i.e., the vertical tilt angle) directly affect the structural safety and stability. If the angle is too large, it can lead to potential problems such as load eccentricity and connection failure. Therefore, accurate measurement of the angles in both directions is necessary during construction and acceptance.

[0004] Currently, construction sites often use ordinary protractors, spirit levels, or theodolites for measurements. For example, a spirit level is used in conjunction with a protractor to measure vertical tilt, while a theodolite or total station is used to measure horizontal deflection. These methods have several significant drawbacks: First, they require multiple instruments, making operation cumbersome and inefficient; second, it's difficult to standardize measurement benchmarks, usually requiring separate instrument setups, which can easily introduce cumulative errors; and third, they cannot be used for real-time measurements during the I-beam overlapping process, requiring only static verification after the overlap is completed, which hinders dynamic adjustments during construction. Summary of the Invention

[0005] The purpose of this invention is to provide an I-beam installation angle measuring device that can simultaneously measure the relative angle between the horizontal and vertical directions. It can be used as a whole for lap joint acceptance or disassembled for real-time measurement during the installation process, thereby improving construction efficiency and adaptability.

[0006] The objective of this invention is achieved through the following technical solution: an I-beam installation angle measuring device, comprising a first fixed plate assembly, a second fixed plate assembly, an adjustable shaft seat, a first indicator, a second scale, a second indicator, and a multi-purpose shaft.

[0007] The adjustable shaft seat includes a sliding shaft seat, and the second scale part includes a second angle disk and an inner arm. The sliding shaft seat is slidably connected to the main body of the second fixed plate assembly. The inner arm is fixedly connected to the main body of the first fixed plate assembly. The middle part of the second angle disk is fixedly connected to the middle part of one side of the inner arm.

[0008] The first indicator part includes a first indicator shaft, a first pointer and a first reference plate. The second indicator part includes a horizontal slider. The first indicator shaft is inserted in the sliding shaft seat. The inner end of the first reference plate is screwed to the first indicator shaft. The first pointer is fixed to the top of the first indicator shaft. The inner end of the first reference plate is fixed with a first angle disk centered on the first indicator shaft.

[0009] The first reference plate can be magnetically attracted to the main body of the first fixed plate assembly;

[0010] A vertical slider is slidably connected to the outer end of the first reference plate, a horizontal slider is slidably connected to one side of the vertical slider, and a second pointer is fixed to one side of the horizontal slider.

[0011] The multi-purpose shaft includes a flexible ball head, and a shaft is slidably inserted into the middle of the inner arm. The flexible ball head is elastically supported and slidably inserted into the head end of the shaft.

[0012] The technical solution of this invention is used as follows:

[0013] The device can simultaneously measure the relative angles of the horizontal planes and the vertical planes of the overlapping cantilevered I-beams and the spreader beam I-beams.

[0014] The first fixing plate assembly is magnetically attracted to the I-beam of the spreader beam, and the second fixing plate assembly is magnetically attracted to the cantilever I-beam. The main body of the first fixing plate assembly is attached to the side of the I-beam of the spreader beam, and the main body of the second fixing plate assembly is attached to the side of the cantilever I-beam.

[0015] When in use as a whole, the main side of the first fixing plate assembly needs to be attached to the side of the spreader beam I-beam, and the main side of the second fixing plate assembly needs to be attached to the side of the cantilever I-beam. The first reference plate and the main body of the first fixing plate assembly form a magnetic attraction. After they are attached in all places, the first fixing plate assembly and the spreader beam I-beam and the second fixing plate assembly and the cantilever I-beam are magnetically fixed. At this time, the whole device is straddled between the two I-beams.

[0016] The first reference plate and the main body of the first fixed plate assembly are magnetically attracted to each other to ensure that the reference is in contact; at the same time, the insert shaft in the multi-purpose shaft part is inserted from the inner arm into the middle of the horizontal slider, so that the horizontal slider and the middle of the second angle disk are rotatably connected, and the second pointer can indicate the scale value on the second angle disk in real time.

[0017] Measurement of horizontal angle: When the cantilevered I-beam deflects horizontally relative to the spreader beam I-beam, the second fixed plate assembly drives the adjustable shaft seat and the first indicator shaft to rotate synchronously. The first pointer fixed to the top of the first indicator shaft rotates relative to the first angle disk fixed on the first reference plate, and the scale value indicated is the relative angle between the horizontal planes.

[0018] Measurement of vertical angle: When the cantilevered I-beam tilts vertically relative to the spreader beam I-beam, it will cause the first reference plate to tilt. The tilt of the first reference plate will cause the vertical slider and the horizontal slider to produce a compound motion. At this time, since the insertion shaft has been inserted into the horizontal slider, the second pointer on one side of the horizontal slider will rotate around the center of the second angle disk. The scale value indicated by it is the relative angle between the vertical planes.

[0019] This status is applicable to rapid verification after two I-beams have been overlapped;

[0020] When disassembled for use, the magnetic attraction between the first reference plate and the main body of the first fixed plate assembly is released, and the insert shaft in the multi-purpose shaft part is pulled out from the horizontal slider. Only the elastic ball head protrudes from the inner arm. At this time, the elastic ball head can be used as a temporary positioning or elastic locking point for quick positioning and engagement with the horizontal slider when used independently.

[0021] The mechanism consisting of the first fixed plate assembly, the second scale part and the multi-purpose shaft part is magnetically attracted and fixed to the spreader beam I-beam. Another mechanism consisting of the second fixed plate assembly, the adjustable shaft seat part and the second indicator part is magnetically attracted and fixed to the cantilever I-beam. After the two sets of mechanisms are installed, the first reference plate can be moved by the movement of the adjustable sliding shaft seat, so as to move the first reference plate to the position where it is magnetically attracted to one side of the main body of the first fixed plate assembly.

[0022] After the first reference plate and the main body side of the first fixed plate assembly are in place, the scale value indicated by the first pointer on the first angle dial is the relative angle between the horizontal planes.

[0023] By manually moving the vertical and horizontal sliders, the middle of the horizontal slider is elastically engaged with the elastic ball head. At this time, the scale value indicated by the second pointer on the second angle dial is the relative angle between the vertical planes.

[0024] This status applies to real-time measurements during the installation of two I-beams.

[0025] By adopting the above technical solution, the present invention can achieve the following beneficial effects:

[0026] (1) This invention can be used for verification measurement after the cantilever I-beam and the spreader beam I-beam are connected in place. The device can be connected as a whole between the spreader beam I-beam and the cantilever I-beam. The first fixed plate assembly and the second fixed plate assembly are magnetically attracted to the side of the corresponding I-beam respectively. The insert shaft is inserted into the middle of the horizontal slider to form a rigid rotational connection. At this time, without step-by-step operation, the relative angle between the first pointer and the first angle disk indicating the horizontal plane and the relative angle between the second pointer and the second angle disk indicating the vertical plane can be read simultaneously. This mode is designed for rapid verification after the connection is completed. It can obtain the angle deviation in two directions at one time, which can significantly shorten the acceptance time.

[0027] (2) When the two I-beams have not yet completed the final overlap, or the overlap positions are far apart, the mechanism consisting of the first fixed plate assembly, the second scale part and the multi-purpose shaft part can be magnetically attracted to the spread beam I-beam, and the other mechanism consisting of the second fixed plate assembly, the adjustable shaft seat part and the second indicator part can be magnetically attracted to the cantilever I-beam. As the two I-beams move to the overlap position, with the translation adjustment of the sliding shaft seat, the first reference plate and the main body side of the first fixed plate assembly can be magnetically attached. The first pointer can be read in real time to indicate the horizontal angle on the first angle plate, and the second pointer can be read on the second angle plate after the middle part of the horizontal slider and the elastic ball head are elastically engaged by moving the vertical slider and the horizontal slider. This allows for simultaneous construction and measurement, greatly expanding the adaptability of on-site construction. Attached Figure Description

[0053] Example 1:

[0054] Examples of the overall measurement usage mode of this invention Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 13 and Figure 14 As shown;

[0055] The sliding shaft seat 301 in the adjustable shaft seat 3 is slidably connected to the main body of the second fixed plate assembly 2 and can be adjusted by translation. The inner arm 502 is fixedly connected to the main body of the first fixed plate assembly 1, and the middle part of the second angle plate 501 is fixedly connected to the middle part of one side of the inner arm 502.

[0056] A first indicator shaft 401 is inserted in the sliding shaft seat 301. The inner end of the first reference plate 403 is screwed to the first indicator shaft 401. A first pointer 402 is fixed to the top end of the first indicator shaft 401. A first angle disk 406 is fixed to the inner end of the first reference plate 403 with the first indicator shaft 401 as the center. The first pointer 402 can rotate relative to the first angle disk 406 to indicate the scale value on the first angle disk 406.

[0057] The first reference plate 403 can be magnetically attracted to the main body of the first fixed plate assembly 1, so that the first reference plate 403 can fit against the main body of the first fixed plate assembly 1 and can move relative to each other through friction.

[0058] A vertical slider 602 is slidably connected to the outer end of the first reference plate 403, and a horizontal slider 604 is slidably connected to one side of the vertical slider 602. The moving direction of the horizontal slider 604 is perpendicular to the moving direction of the vertical slider 602. A second pointer 605 is fixed to one side of the horizontal slider 604. The second pointer 605 can indicate the scale value on the second angle disk 501.

[0059] A shaft 702 is slidably inserted in the middle of the inner arm 502. When the first reference plate 403 and the main body of the first fixed plate assembly 1 are magnetically attracted, the shaft 702 can be inserted from the inner arm 502 into the middle of the horizontal slider 604, so that the second pointer 605 can rotate relative to the center of the second angle disk 501.

[0060] The working principle is as follows:

[0061] The device can simultaneously measure the relative angles of the horizontal plane and the vertical plane of the overlapping cantilevered I-beams and the spreader beam I-beams.

[0062] The first fixing plate assembly 1 is magnetically attracted to the I-beam of the spreader beam, and the second fixing plate assembly 2 is magnetically attracted to the cantilever I-beam. The main body of the first fixing plate assembly 1 is attached to the side of the I-beam of the spreader beam, and the main body of the second fixing plate assembly 2 is attached to the side of the cantilever I-beam.

[0063] The device can be used as a whole. The first reference plate 403 is magnetically attracted to the main body of the first fixed plate assembly 1. The insert shaft 702 is inserted from the inner arm 502 into the middle of the horizontal slider 604. The second pointer 605 can rotate relative to the center of the second angle disk 501.

[0064] When in use as a whole, the main side of the first fixing plate assembly 1 needs to be attached to the side of the spreader beam I-beam, and the main side of the second fixing plate assembly 2 needs to be attached to the side of the cantilever I-beam. The first reference plate 403 and the main body of the first fixing plate assembly 1 form a magnetic attraction. After they are attached in all places, the first fixing plate assembly 1 and the spreader beam I-beam and the second fixing plate assembly 2 and the cantilever I-beam are magnetically fixed. At this time, the whole device is straddled between the two I-beams.

[0065] The first reference plate 403 and the main body of the first fixed plate assembly 1 are magnetically attracted to each other to ensure that the reference is in contact; at the same time, the insert shaft 702 in the multi-purpose shaft part 7 is inserted from the inner arm 502 into the middle of the horizontal slider 604, so that the horizontal slider 604 and the middle of the second angle disk 501 are rotatably connected, and the second pointer 605 can indicate the scale value on the second angle disk 501 in real time.

[0066] Measurement of horizontal angle: When the cantilevered I-beam deflects horizontally relative to the spreader beam I-beam, the second fixed plate assembly 2 drives the adjustable shaft seat 3 and the first indicator shaft 401 to rotate synchronously. The first pointer 402, which is fixed to the top of the first indicator shaft 401, rotates relative to the first angle disk 406 fixed on the first reference plate 403. The scale value indicated by the pointer is the relative angle between the horizontal planes.

[0067] Measurement of vertical angle: When the cantilevered I-beam tilts vertically relative to the spreader beam I-beam, it will cause the first reference plate 403 to tilt. The tilt of the first reference plate 403 will cause the vertical slider 602 and the horizontal slider 604 to produce a compound motion. At this time, since the insertion shaft 702 has been inserted into the horizontal slider 604, the second pointer 605 on one side of the horizontal slider 604 will rotate around the center of the second angle disk 501, and the scale value indicated by it is the relative angle between the vertical planes.

[0068] This procedure is suitable for rapid measurement and verification after two I-beams have been overlapped.

[0069] The specific structure of the first fixed plate assembly 1 and the second scale part 5 is as follows: Figure 2 , Figure 3 and Figure 4 As shown, the first fixing plate 101 serves as the main body of the first fixing plate assembly 1. The second scale position 104 is opened at the lower end of the first fixing plate 101. The fixing magnetic strip 103 is symmetrically installed and fixed on the outer side of the first fixing plate 101 with the second scale position 104 as the center, and is flush with or not higher than the outer side of the first fixing plate 101.

[0070] A first pressing seat 105 is symmetrically fixed at the upper end of the first fixed plate 101. A first pressing groove 106 is evenly opened in the first pressing seat 105. A first pressing slide 107 is evenly fixed on both sides of the first magnetic seat 102. The first pressing slide 107 on the same side is slidably connected to the first pressing groove 106. A first inner limit 108 is fixed at the inner end of the first pressing slide 107. A first outer limit 109 is fixed between the outer ends of the first pressing slide 107 on the same side. A first top spring 110 is locked between the first outer limit 109 and the first fixed plate 101. A first locking platform 111 is symmetrically fixed on the inner side of the first fixed plate 101.

[0071] Under the elastic support of the first top spring 110, the first magnetic seat 102 can be elastically moved away from the inner side of the first fixed plate 101 in the free state.

[0072] After the first fixing plate 101 is properly attached to the I-beam of the carrying pole beam, and the first locking plate 111 is inserted into the inner cavity of the I-beam, the first magnetic seat 102 is pressed against one side of the I-beam to overcome the supporting elasticity of the first top spring 110, so that the magnetic surface of the first magnetic seat 102 is attached to the main body of the I-beam. Then, by rotating the knob of the first magnetic seat 102, the first magnetic seat 102 generates magnetic force, magnetically fixing the first fixing plate assembly 1 to the I-beam of the carrying pole beam; the inner arm 502 and the second scale The inner wall of position 104 is fixedly connected, and the hexagonal seat 503 is installed and fixed at the center of the inner arm 502. The center of the second angle plate 501 is provided with a hexagonal slot 504. The second angle plate 501 is sleeved at the junction of the hexagonal seat 503 and the inner arm 502 through the hexagonal slot 504. After the inner side of the fastening cylinder 505 is pressed against the end face of the second angle plate 501, its cylinder wall is fixed to the outer wall of the hexagonal seat 503, so that the center of the second angle plate 501 and the center of the inner arm 502 are fixed and do not rotate relative to each other.

[0073] The specific structures of the second fixed plate assembly 2, the adjustable shaft seat 3, and the first indicator 4 are as follows: Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the second fixing plate 201 serves as the main body of the second fixing plate assembly 2. The inner side of the second fixing plate 201, away from the first fixing plate assembly 1, is symmetrically fixed with a second locking platform 203 for locking into the inner cavity of the I-beam.

[0074] The second fixed plate 201 is symmetrically fixed with a second pressing seat 204 at one end away from the first fixed plate assembly 1. Each set of second pressing seats 204 is evenly provided with a second pressing groove 205. The second magnetic seat 202 is evenly fixed with a second pressing slide 206 on both sides. The inner side of the second pressing slide 206 is fixed with a second inner limit 207. The outer ends of the second pressing slide 206 on the same side are fixed with a second outer limit 208. The second outer limit 208 and the second fixed plate 201 are locked with a second top spring 209.

[0075] Similarly, under the elastic support of the second top spring 209, the second magnetic seat 202 can be elastically moved away from the inner side of the second fixed plate 201 in the free state.

[0076] After the second fixing plate 201 is attached to the cantilever beam I-beam and the second locking plate 203 is inserted into the inner cavity of the I-beam, the second magnetic seat 202 is pressed against one side of the I-beam to overcome the supporting elastic force of the second top spring 209, so that the magnetic surface of the second magnetic seat 202 is attached to the main body of the I-beam. Then, by rotating the knob of the second magnetic seat 202, the second magnetic seat 202 generates magnetic force to magnetically fix the second fixing plate assembly 2 to the cantilever beam I-beam.

[0077] The first magnetic base 102 and the second magnetic base 202, as a prior art, typically include a base and a rotatable knob. Their working principle is based on magnetic circuit switching. By rotating the knob, the relative position of the internal permanent magnets can be changed, thereby controlling the path of the magnetic lines of force.

[0078] When the knob is in the open position, the internal magnetic circuit is guided, allowing the magnetic lines of force to pass through the bottom of the base and extend to the outside, thereby generating a strong attraction force and achieving a firm connection with ferromagnetic objects; when the knob is rotated to the closed position, the internal magnetic circuit is reconfigured, so that the magnetic lines of force form a closed loop inside the base, and the external magnetic field almost disappears, thereby deactivating the connection and making it easy to remove the object.

[0079] The other end of the second fixed plate 201 is symmetrically provided with an adjustment groove 302, and the inner side of the sliding shaft seat 301 is symmetrically fixed with an adjustment slide rail 303, and the adjustment slide rail 303 on the same side is slidably connected in the adjustment groove 302.

[0080] The adjusting screw slider 304 is fixedly installed on the middle of the inner side of the sliding shaft seat 301. The two ends of the adjusting screw 305 are screwed to the inner side of the second fixed plate 201 through the screw screw seat 308. The adjusting screw slider 304 and the adjusting screw 305 are connected in cooperation.

[0081] The knob 306 is inserted into one end of the adjusting screw 305, and the second fixing plate 201 body is provided with a relief groove 309 for eliminating interference with the adjusting screw slider 304 and the knob 306;

[0082] By turning the knob 306, the adjusting screw 305 and the adjusting screw slider 304 are driven to form a transmission, which enables the sliding shaft seat 301 to move with the sliding engagement of the adjusting slide rail 303 and the adjusting slide groove 302 as the guide. The moving direction of the sliding shaft seat 301 is parallel to the setting direction of the second clamping platform 203, that is, the setting direction of the cantilever beam I-beam.

[0083] An outer stop 307 is also fixedly installed at the outer end opening of the adjusting slide 302 to prevent the adjusting slide 303 from moving beyond its travel range.

[0084] One end of the first reference plate 403 is fixed with a pair of first rotating seats 404, and the top of the first rotating seats 404 at the top is fixed with a snap-fit ​​boss 405. The middle part of the first angle plate 406 is snapped with the snap-fit ​​boss 405.

[0085] The magnetic strips 407 are fixedly installed in pairs on the outer side of the first reference plate 403 to form a magnetic connection with the fixed magnetic strip 103. Similarly, the magnetic strips 407 are flush with or not higher than the outer side of the first reference plate 403.

[0086] Furthermore, within the range where the outer surfaces of the first reference plate 403 and the first fixed plate 101 are in contact, the magnetic strips 407 can form a magnetic attraction with the fixed magnetic strips 103; and the setting direction of the first indicator shaft 401 is perpendicular to the moving direction of the sliding shaft seat 301. The first rotating seat 404 is screwed to the first indicator shaft 401. The top end of the first indicator shaft 401 passes through the snap-fit ​​boss 405 and is fixed to the first pointer 402. The snap-fit ​​boss 405 will not interfere with the rotation of the first pointer 402.

[0087] The specific structures of the second indicator section 6 and the multi-purpose shaft section 7 are as follows: Figure 9 , Figure 10 and Figure 11 As shown, the vertical slide rail 601 is fixed to the other end of the first reference plate 403, the vertical slider 602 is slidably connected to the vertical slide rail 601, the horizontal slide rail 603 is fixed to one side of the vertical slider 602, and the setting direction of the vertical slide rail 601 is parallel to the setting direction of the first indicator shaft 401, while the setting direction of the horizontal slide rail 603 is perpendicular to the setting direction of the vertical slide rail 601.

[0088] The horizontal slider 604 is slidably connected to the horizontal slide rail 603, and the second pointer holder 607 is fixed to the middle of the inner side of the horizontal slider 604. The horizontal slider 604 and the second pointer holder 607 are both provided with a shaft hole 608.

[0089] The center of the second pointer 605 is fixed to the outer wall of the second pointer holder 607;

[0090] The square groove 701 is horizontally opened in the horizontal slide rail 603, and its width is greater than the outer diameter of the insert shaft 702, so it will not interfere with the movement of the insert shaft 702.

[0091] The insert shaft 702 is inserted into the inner hole of the hexagonal seat 503 and can move between the hexagonal seat 503 and the shaft hole 608;

[0092] The side walls of the vertical slider 602, the horizontal slider 604, and the hexagonal seat 503 are all threaded with locking bolts 606, which can play a role in sliding locking.

[0093] When the device is in use as a whole, the locking bolts 606 on the vertical slider 602 and the horizontal slider 604 are screwed into the loose position without affecting the free sliding of the vertical slider 602 and the horizontal slider 604. After moving the insertion shaft 702 to the position through the shaft hole 608, the locking bolts 606 on the hexagonal seat 503 are screwed into the insertion shaft 702 to lock it, so that the horizontal slider 604 can be rotated with the insertion shaft 702 through the shaft hole 608.

[0094] Example 2:

[0095] Based on Embodiment 1, the present invention elastically slides and inserts an elastic ball head 704 into the head end of the insertion shaft 702, and the split measurement mode is illustrated in the following example. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 13 As shown;

[0096] The head end of the insert shaft 702 in the multi-purpose shaft part 7 is provided with an insertion groove 706, and the end of the elastic ball head 704 is fixed with an insertion post 705. The insertion post 705 is slidably inserted into the insertion groove 706. The compression spring 707 is sleeved on the outer wall of the insertion post 705, and one side is locked with the end of the elastic ball head 704, and the other side is locked with the head end of the insert shaft 702.

[0097] The compression spring 707 can provide an elastic thrust to the elastic ball head 704 away from the insertion shaft 702, so that when the head end of the elastic ball head 704 is pressed, it can produce an elastic contraction relative to the insertion shaft 702.

[0098] When the device is disassembled for use, the first fixed plate assembly 1, the second scale part 5 and the multi-purpose shaft part 7 form a mechanism that magnetically attracts the I-beam of the spreader beam, and the second fixed plate assembly 2, the adjustable shaft seat part 3 and the second indicator part 6 form a mechanism that magnetically attracts the cantilevered I-beam.

[0099] Release the magnetic attraction between the first reference plate 403 and the main body of the first fixed plate assembly 1, and pull out the insert shaft 702 in the multi-purpose shaft part 7 from the horizontal slider 604. Only the elastic ball head 704 protrudes from the inner arm 502. At this time, the elastic ball head 704 can be used as a temporary positioning or elastic locking point for quick positioning and engagement with the horizontal slider 604 when used independently.

[0100] After moving the insert shaft 702 to a position where only the elastic ball head 704 protrudes from the inner arm 502, tighten the locking bolt 606 in the hexagonal seat 503. This allows the vertical slider 602 and the horizontal slider 604 to be moved manually. The horizontal slider 604 forms an elastic snap-fit ​​with the elastic ball head 704 through the shaft hole 608, which facilitates the quick and accurate positioning of the second pointer 605 in conjunction with the indication of the second angle disc 501.

[0101] The mechanism consisting of the first fixed plate assembly 1, the second scale part 5 and the multi-purpose shaft part 7 is magnetically attracted and fixed to the spreader beam I-beam. Another mechanism consisting of the second fixed plate assembly 2, the adjustable shaft seat part 3 and the second indicator part 6 is magnetically attracted and fixed to the cantilever I-beam. After the two mechanisms are installed, the first reference plate 403 can be moved by the movement of the adjustable sliding shaft seat 301, so that the first reference plate 403 can be moved to the position where it is magnetically attracted to one side of the main body of the first fixed plate assembly 1.

[0102] After the first reference plate 403 is attached to the main body side of the first fixed plate assembly 1, the scale value indicated by the first pointer 402 on the first angle disk 406 is the relative angle between the horizontal planes.

[0103] By manually moving the vertical slider 602 and the horizontal slider 604, the middle part of the horizontal slider 604 is elastically engaged with the elastic ball head 704. At this time, the scale value indicated by the second pointer 605 on the second angle dial 501 is the relative angle between the vertical planes. This mode is suitable for real-time measurement during the installation of two I-beams.

[0104] The tailstock 703 is fixed to the end of the insert shaft 702, which can limit the switching between the two different modes of the device. When the tailstock 703 abuts against the end of the hexagonal seat 503, the insert shaft 702 extends into place and the device enters the overall measurement mode. When the tailstock 703 abuts against the inner surface of the end of the snap-fit ​​cylinder 505, the insert shaft 702 retracts into place and the device enters the split measurement mode. The presence of the snap-fit ​​cylinder 505 will not interfere with the tightening of the locking bolt 606 on the side wall of the hexagonal seat 503.

[0105] Furthermore, as is well known to those skilled in the art, the device selects different materials according to the stress characteristics and functional requirements of each component. For parts involving rotational positioning and sliding fit, i.e., locations requiring rigid support, 45# steel, tool steel, or spring steel are used to ensure sufficient rigidity, wear resistance, and deformation resistance. For non-primary load-bearing or lightly loaded parts, aluminum alloy or magnesium alloy is used. Under the premise of meeting basic strength and dimensional stability, this significantly reduces the overall weight of the device, making it easier to handhold, move, and operate by a single person on site.

[0106] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
