Description

Displacement measurement system

A displacement measurement system, especially a system that provides support for a building structure in the event of a deformation-induced event.

Today's architectural braces are used to provide support between architectural features to prevent excessive movement of building features relative to each other. One form of construction scaffolding acts as a stabilizing device to resist damage caused by a deformation inducing event, and it may have a core member and a buckling restraining assembly. The core member may be formed of metal and have a first end and a second end attached to the architectural feature and having an intermediate portion between the first end and the second end. The setback assembly can have a cement layer surrounding the intermediate portion of the core member to resist deformation of the intermediate portion, and have a metal housing and define an interior space to receive the cement layer and position the cement layer. An example building bracket is disclosed in U.S. Patent No. 7,174,680.

This building support can help the building maintain structural integrity in the event of a deformation-induced event. However, in a deformation-induced event, the deformation caused by the core member may exceed the elastic limit of its material. Also, deformation induced events may cause the core members to experience alternating tension and pressure displacement. This reverse loading may weaken the material of the building support, thereby reducing the likelihood that the building support will experience another deformation-induced event.

Therefore, after a deformation-induced event occurs, it may be necessary to test the structural support to confirm whether it needs to be replaced with a new construction support. However, since the intermediate portion of the core member is encapsulated in the cement layer, the intermediate portion of the core member cannot be directly detected without damaging the building bracket. Due to the complexity of the building structure, even if the scale of the deformation-induced event is known, the strain actually experienced by the building support is still difficult to predict.

Even though the maximum strain experienced by the building support is known, it may not be sufficient to assess the structural integrity of the core member without more information about the total number and/or amplitude of the reverse load experienced by the core member. Therefore, there is a need in the art to develop a system and method for confirming the need to replace a building support after a deformation induced event occurs.

Some embodiments described in this disclosure relate to systems and methods for supporting a building, and more particularly to systems and methods for providing support to a building structure in the event of a deformation-induced event. The "deformation-induced event" refers to an event that causes deformation in a building structure, and may include seismic events such as earthquakes, tremors, and aftershocks. Such deformation-inducing events may include storms, thermal displacements, and explosion events.

Some embodiments described in this disclosure relate to systems and methods for measuring displacement caused by strain in a building support. However, it should be understood that systems and methods for measuring displacement and/or determining strain in the present disclosure are applicable to a variety of applications, in accordance with some embodiments. For example, the systems and methods described in this disclosure can be used to measure displacement in, and/or among, machines and equipment subjected to shock and vibration, such as concrete and asphalt grinders, classifiers. Blades, bulldozers, loaders, trucks with dump trucks, tractors, self-propelled windrowers and combination machines, and machines with tool head position control. In another example, the systems and methods described herein can be used to measure displacement in machinery or equipment for a wide variety of building monitoring, such as door position monitoring, long term wall sensing, long term roofing Test and so on. In yet another example, the systems and methods described herein can be used to measure low-cost resolution position feedback systems in the industry as useful machinery or equipment, such as assembly line systems and conveyor belt systems.

As used herein, "displacement" refers to the relative motion between portions of one or more members, such as relative motion between the ends of the beam due to deformation of the beam, which may include linear, rotational, and/or mixed displacements. As used herein, "architecture" means any structural element, component or component that is incorporated into a building, bridge, oil rig or other ground attachment structure. However, as previously stated, it should be understood that the systems and methods described in this disclosure can have a variety of other applications.

As used herein, "building bracket" means and includes any member that provides mechanical support to the structure. Such components may include any stabilizing device, thermal link, damper or other structural member known in the art. In some embodiments, the building support has a core member, wherein the core member has a first end and a second end attachable to the architectural feature, and an intermediate portion between the first end and the second end . The building bracket may further have a setback assembly that surrounds the intermediate portion to resist deformation of the intermediate portion. The frustum bundle assembly can have a cement layer surrounding the intermediate portion of the core member to resist deformation of the intermediate portion, and have a metal shell and define an interior space to accommodate the cement layer and position the cement layer.

The displacement measuring device can be used to measure the displacement in the core member caused by the strain in the core member. The displacement measuring device can have a first coupling member having a first attachment feature secured to the first end of the core member and a second coupling member having a second attachment feature secured to a second end of the core member. The second coupling member is displaceable from the first coupling member due to displacement. Also, the system can have a sensor to measure a plurality of changes in the displacement produced over a period of time. The sensor can provide measurement data indicative of the change.

In some embodiments, the displacement measuring device can penetrate the interior of the housing and penetrate the cement. In an alternate embodiment, the displacement measuring device can extend to the exterior of the cement but is still maintained by the housing. In other embodiments, the displacement measuring device can be independently disposed relative to the housing (ie, only coupled to the first end and the second end of the core member and not surrounded by any portion of the housing).

The measurement data can be received by a computing device that can be used to view and/or manipulate the measurement data. Additionally or alternatively, the displacement measuring device can have an integrated component that can be used to view and/or manipulate data without the need for a separate computing device. Additionally or alternatively, a plurality of displacement measuring devices (eg, displacement measuring devices coupled to different building supports in a building) can be connected to a single computing device via a wired and/or wireless connection for delivery Measuring data.

The displacement measuring device can have a power source, such as a battery that powers the sensor. If desired, the sensor can operate in a sleep mode that does not produce measurement data. When a deformation-induced event occurs, the sensor (or a different sensor of the displacement measuring device) can detect the onset of the deformation-induced event and switch the sensor to an active mode that produces the measured data. In this way, the life of the power supply can be extended. In some embodiments, the power supply can be designed to remain in a charging state for several years without requiring replacement or recharging.

In the embodiment in which the displacement measuring device stores the measurement data, the displacement measuring device can further have a memory for recording the measurement data, and then can send the measurement data to the input/output module by using the displacement measuring device. Computing device. The displacement measuring device can have an outer casing that houses the above components and protects the components from intrusion of particulate matter, and the housing is preferably sealed to substantially prevent solid matter from entering the interior thereof. Therefore, if the displacement measuring device is embedded in the cement, the intrusion of cement dust and particles which may be generated in the cement can be prevented during the deformation inducing event. Advantageously, the sensor can measure a change in displacement between the first coupling and the second coupling at a plurality of points in time during the deformation inducing event. Therefore, the measurement data can display not only the maximum displacement change, but also the manner in which the displacement between the first coupling member and the second coupling member changes with time during the deformation inducing event, and this information can be used to calculate the strain. In some embodiments, the relevant features of the core member can be programmed into the sensor such that the measurement data does not require further calculations to provide strain to the core member.

The deformation experienced by the core member can be very large and can be on the order of a few inches. Many known displacement sensors may not be suitable for measuring displacements within this range. Thus, the sensor of the displacement measuring device can have a configuration designed to facilitate measurement of relatively large displacement changes.

In some embodiments, the sensor can have a first conductive contact fixed to a fixed position relative to the first coupling, and a plurality of additional conductive contacts that are fixed relative to the second coupling Set in a number of fixed positions. The first electrically conductive contact is movable along an axis relative to the plurality of additional electrically conductive contacts in response to a change in displacement between the first coupling and the second coupling. The additional conductive contacts may be distributed along the axis such that the contact between the first conductive contact and any of the additional conductive contacts is represented as a particular magnitude of displacement and the circuitry specific to one of the additional conductive contacts is closed to produce Represented as a subset of the measured data related to the magnitude of the displacement.

The system 100 of Figure 1 represents only one of many possible configurations within the scope of this creation. Those skilled in the art will recognize many possible modifications with the assistance of this disclosure. For example, computing device 120 can be designed to maintain constant communication with displacement measuring device 110. Thus, if desired, memory 144 and/or processor 148 may be omitted from displacement measuring device 110 and measurement data 142 may be transmitted directly to computing device 120.

In this case, the displacement measuring device can perform the function of the computing device, so that a computing device independent of the displacement measuring device is not required.

Please refer to FIGS. 2A and 2B, which are respectively a perspective view and an exploded perspective view showing the displacement measuring device 110 for measuring the displacement in the building bracket 130 according to some embodiments, wherein the displacement measuring device 110 is worn. Through the interior of the building bracket 130. The computing device 120 is not shown in Figures 2A and 2B, but can be used in conjunction with the displacement measurement 110 described in the description of Figure 1 above.

The building bracket 130 can have a structure as described in U.S. Patent No. 7,174,680, which is incorporated herein by reference. In particular, the building bracket 130 can have a core member 200 and a setback assembly 220. The core member 200 can be fixed to architectural features (not shown) of the building to limit relative motion between the building features, particularly in the case of deformation induced events. Thus, core member 200 can be designed to accept various loading modes, including tension, pressure, bending, twisting, and/or combinations thereof. The core member 200 is sealed into the setback assembly 220 by preventing the core member 200 from being bent in the setback assembly 220 such that the core member 200 is more resistant to bending when pressed. The building brackets 130 shown in Figures 2A and 2B are merely exemplary and construction brackets of various shapes and sizes can be used in conjunction with the systems and methods of the present disclosure.

The core member 200 can have a first end 202, a second end 204, and an intermediate portion 206 between the first end 202 and the second end 204. The first end portion 202 and the second end portion 204 can each have an anchor flange 208 to facilitate attachment of the first end portion 202 and the second end portion 204 to the architectural features to be maintained. The anchor flange 208 can have holes or other mounting features that facilitate attachment of the first end 202 and the second end 204 to the architectural features. Also, the first end portion 202 and the second end portion 204 can each have a device anchor projection 210 that can selectively extend from the anchor flange 208 as shown.

The setback assembly 220 can have a cement layer 222 that surrounds the intermediate portion 206 of the core member 200, and a casing 224 that surrounds the cement layer 222 to maintain the cement layer 222 in place. The cement layer 222 can be formed around the intermediate portion 206 such that the cement layer 222 surrounds and contacts the intermediate portion 206 to resist bending of the intermediate portion 206. In FIG. 2B, a cement layer 222 is shown, which indicates that the cement layer 222 is present inside the outer casing 224 as a whole. The outer casing 224 can substantially surround the cement layer 222.

The outer casing 224 can have a peripheral portion 230 that extends generally parallel to the length of the intermediate portion 206, and an end plate 232 that covers the open end of the peripheral portion 230. As shown in FIG. 2B, the peripheral portion 230 can have a square cross-sectional shape or, in the alternative, can have a rectangular, circular, elliptical or other cross-sectional shape. At each end of the peripheral portion 230, the end plate 232 can be divided into two plates such that the end plates 232 can be secured together and surround the first end 202 and the second end 204 of the corresponding core member 200. A convex portion of one is fixed to the peripheral portion 230 as shown in Fig. 2A. The end plate 232 need not cooperate with the peripheral portion 230 to form a hermetic seal around the cement layer 222, but preferably seals the cement layer 222 to a level sufficient to retain the cement layer 222 within the outer casing 224.

If desired, the end plate 232 can have an aperture 234 that secures the displacement measuring device 110 to the first end 202 and the second end 204 through the end plate 232 of the housing 224. A cylindrical cavity 240 may be present within the cement layer 222 through which the displacement measuring device 110 may pass. If desired, the cylindrical cavity 240 can be defined by a tubular wall to isolate the displacement measuring device 110 from the cementitious layer 222. Alternatively, the displacement measuring device 110 can be implemented by its own housing, which will be described later. If desired, the displacement measuring device 110 can be disposed inside the outer casing 224 and the cement layer 222 can be poured to define the cylindrical cavity 240 such that the cement layer 222 is formed around the displacement measuring device 110.

The displacement measuring device 110 can have a housing 250 , a first coupling 252 and a second coupling 254 . The housing 250 can protect the internal components of the displacement measuring device 110 from intrusion of particulate matter, such as may be released from the cement layer 222, particularly during deformation induced events. The first coupling 252 can be secured to the first end 202 of the core member 200 and the second coupling 254 can be secured to the second end 204 of the core member 200.

The displacement measuring device 110 can detect the relative positional change of the first coupling member 252 and the second coupling member 254 to detect the movement of the first end portion 202 relative to the second end portion 204 (ie, the first The displacement between the end 202 and the second end 204 varies). The second coupling 254 can be coupled to the housing 250 via a rod 256, wherein the rod 256 can be slid into and out of the housing 250, or can be secured to one portion of the housing relative to the remainder of the housing Sliding (eg, telescopically) is performed to allow relative movement between the first coupling 252 and the second coupling 254. By varying the length of the rod 256, the displacement measuring device 110 can be easily adapted to building supports of various lengths.

Each of the first coupling 252 and the second coupling 254 can have an attachment feature that facilitates connection with an associated one of the first end 202 and the second end 204. In the exemplary embodiment of FIG. 2B, the first coupling member 252 and the second coupling member 254 can each have attachment features in the form of locking holes 260. The locking aperture 260 of the first coupling 252 can facilitate attachment of the first coupling 252 to the first end 202 or, more specifically, to the device anchor of the first end 202 210, which is passed through the locking hole 260 through a locking member 262 such as a screw, a bolt or a rivet, and is inserted through a corresponding hole in the device anchor protrusion 210 of the first end portion 202. Similarly, the locking aperture 260 of the second coupling 254 can facilitate attachment of the second coupling 254 to the second end 204 or, more specifically, to the second end 204 The anchoring projections 210 are threaded through the locking holes 260 and through the corresponding holes in the device anchoring projections 210 of the second end portion 204 by using the locking members 262 such as screws, bolts or rivets.

The displacement measuring device 110 is permeable between the first anchor 252 and the device anchor protrusion 210 of the first end 202 of the core member 200, and at the second end of the second coupling 254 and the core member 200. A pair of spacer blocks 264 between the device anchors 210 of 204 are positioned to be offset from the system 100 by a desired offset. Accordingly, the displacement measuring device 110 can be sufficiently displaced from the core member 200 such that the core member 200 can still avoid interference with the operation of the displacement measuring device 110 when the core member 200 is subjected to significant deflection.

The displacement measuring device 110 of Figures 2A and 2B only shows one of many possible displacement measuring devices within the scope of the present disclosure. An alternative displacement measuring device will be shown and described below in conjunction with Figures 3A through 5C.

Please refer to FIGS. 3A and 3B. FIGS. 3A and 3B are respectively a perspective view and an exploded perspective view showing an displacement measuring device of an alternative embodiment. The displacement measuring device 310 can be mounted similar to the displacement measuring device 110 and used to measure the displacement of the building support, such as the building support 130 of Figures 2A and 2B, wherein the strain is caused by strain.

As shown, the displacement measuring device 310 can have a housing 320, a first coupling 322, a second coupling 324, and a sensor 326. The housing 320 can be designed to receive and protect the sensor 326 from foreign matter such as particles from the cement layer 222. The first coupling member 322 can be fixed to the first end of the building bracket, such as the building bracket 130 of FIGS. 2A and 2B, and the second coupling member 324 can be fixed to the second end of the building bracket, for example, Building brackets 130 of Figures 2A and 2B. The sensor 326 can sense a change in displacement between the first coupling 322 and the second coupling 324 to evaluate displacement in the building bracket 130.

The housing 320 can have a first portion 332 and a second portion 334. The first portion 332 telescopically receives the second portion 334 in such a manner that the cavity 336 is defined within the first portion 332 and the second portion 334 of the housing 320. The first portion 332 and the second portion 334 can cooperate in this manner to prevent intrusion of the cavity 336, such as foreign matter from particulate matter from the cement layer 222. Thus, the second portion 334 can have a recess 338 sized to receive the O-ring 340. When in the recess 338, the O-ring 340 can contact the inner surface of the first portion 332 in this manner to provide a seal between the first portion 332 and the second portion 334. However, the seal need not be hermetic, but may only be sufficient to substantially prevent solid matter from entering the cavity 336 to prevent such solid matter from interfering with the operation of the sensor 326.

Also, the first portion 332 and the second portion 334 of the housing 320 can each have a bore 342 that is sized to receive the pin 344. Each pin 344 can extend through the cavity 336 in this manner such that the pin 344 holds the sensor 326 as will be explained later. The pin 344 can be press fit, fastened, welded, and/or otherwise secured to the aperture 342.

The first coupling member 322 and the second coupling member 324 can be designed to be fixed to the end of the core member of the building bracket, such as the first end portion 202 and the second end portion 204 of the core member 200 of the building bracket. Thus, the first coupling member 322 and the second coupling member 324 can each have attachment features that facilitate this fixation. For example, the first coupling member 322 and the second coupling member 324 can each have an aperture 350 through which a fastener such as a screw, a bolt or a rivet can pass to connect the first coupling member 322 and the first The second coupling member 324 is fixed to the first end portion 202 and the second end portion 204.

The sensor 326 can be in the form of a design specifically designed to measure deflection occurring in a building support. The sensor 326 can have a bracket 358 and a slider 360 that rides on the bracket 358 and slides relative to the bracket 358. The bracket 358 can be secured to the first portion 332 of the housing 320 via the first connector 362 and then to the first coupling 322. Similarly, the slider 360 can be secured to the second portion 334 of the housing 320 via the second connector 364 and then to the second coupling 324. Specifically, the slider 360 can be secured to the second connector 364 through a rod 366 that extends parallel to the length of the bracket 358. The spring 368 can be positioned around the wand 366 and can be secured at its ends to the bracket 358 and the slider 360. The sensor 326 can function by detecting the position of the slider 360 on the bracket 358. The spring 368 can assist the slider 360 to move to the neutral position on the bracket 358 without the external force moving the slider 360 to a different position. The configuration and operation of sensor 326 will be shown and described in greater detail later.

Referring to Figure 4, there is shown a perspective view of the displacement measuring device 310 shown in Figures 3A and 3B, wherein the housing 320 is shown in a transparent form to reveal the interior of the displacement measuring device 310. As shown, the open end of the second portion 334 of the housing 320 can be received within the open end of the first portion 332 of the housing 320 such that the first portion 332 and the second portion 334 enclose the cavity 336.

In addition, the pin 344 that is inserted through the hole 342 of the first portion 332 of the housing 320 can also pass through the eyelet 410 formed in the first connector 362 of the sensor 326. Similarly, the pin 344 that is threaded through the aperture 342 of the second portion 334 of the housing 320 can also pass through the eyelet 410 formed in the second connector 364 of the sensor 326. Thus, relative movement between the building elements can cause the first end 202 and the second end 204 of the core member 200 to move relative to each other. The movement can be replicated among the first coupling member 322 and the second coupling member 324 of the displacement measuring device 310. The relative movement between the first coupling member 322 and the second coupling member 324 can cause the first portion 332 and the second portion 334 of the housing 320 to move relative to each other. Thus, the second portion 334 can be further slid inwardly and/or outwardly from the first portion 332 such that the housing 320 is elongated and/or shortened in response to relative movement between the building members.

The relative movement between the first portion 332 and the second portion 334 can be transmitted to the first connector 362 and the second connector 364 of the sensor 326 via the pin 344. Thus, as the architectural features move relative to one another, the first connector 362 can be moved relative to the second connector 364. This movement can cause the slider 360 to move along the carriage 358. The sensor 326 can detect the position of the slider 360 on the cradle 358, which is described in detail in conjunction with FIGS. 5A, 5B, and 5C.

Referring to FIGS. 5A and 5B, FIGS. 5A and 5B are respectively a perspective view and an exploded perspective view showing the sensor 326 of the displacement measuring device 310 shown in FIGS. 3A and 3B. As previously mentioned, the sensor 326 can have a bracket 358, a slider 360, a first connector 362, a second connector 364, a lever 366, and a spring 368. These components are shown in Figure 5A as a complete assembly and are shown separately in Figure 5B. Upon assembly, the slider 360 can slide along the axis 500 on the bracket 358, which can be oriented parallel to the building bracket 130.

The bracket 358 can have a tray 510, a first end wall 512, and a second end wall 514. The tray 510 can extend along the length of the bracket 358, and the first end wall 512 and the second end wall 514 can extend generally perpendicular to the tray 510. The first end wall 512 can have a first aperture 522 and the second end wall 514 can have a second aperture 524. As shown in FIG. 5B, the first connector 362 can be secured to the first end wall 512 through the fastener 526. The fastener 526 can extend through the first aperture 522 of the first end wall 512 and can be coupled by the first connector 362. Wear a place to receive. The bearing 528 can be located in the second bore 524 of the second end wall 514 to receive the rod 366 and such that the rod 366 can slide relatively freely through the second bore 524 of the second end wall 514.

The cradle 358 can have a printed circuit board (PCB) 540 that is located on the tray 510 of the cradle 358. Printed circuit board 540 can be secured to tray 510 via fasteners 542, which can be screws, bolts, rivets, or the like. The printed circuit board 540 can have conductive contacts 544 that can be arranged in a grid pattern on the surface of the printed circuit board 540 that faces the slider 360. More specifically, the conductive contacts 544 can be arranged in a plurality of rows 546, each row 546 extending generally along the width of the printed circuit board 540. Each of the electrically conductive contacts 544 can be a plate, pin or other protruding element formed from a conductive material. Figure 5B shows the presence of four conductive contacts 544 in each row 546, although any other number of contacts may be present in row 546. In an alternative embodiment, the electrically conductive contacts 544 can be arranged as a single line that extends along the axis 500.

Each row 546 of conductive contacts 544 can have conductive contacts 544 arranged in a staggered pattern (ie, the conductive contacts 544 of each row 546 are slightly offset from one another along axis 500). The offset between each pair of adjacent conductive contacts 544 of row 546 can be equal. Moreover, if desired, the same offset can be imparted between the conductive contacts 544 of the adjacent row 546 that are closest to each other along the axis 500, which offset can be equal to the measured resolution of the sensor 326. This staggered pattern is present in the conductive contacts 544 of the printed circuit board 540 of Figure 5B.

For example, if the sensor 326 has a measured resolution of 0.1 inches, each of the conductive contacts 544 of the row 546 can be offset from the adjacent contact by a distance of 0.1 inches along the axis 500. Also, on one side toward the first end wall 512, the conductive contact 544 closest to the row 546 of the first end wall 512 can be offset from the conductive contact 544 furthest away from the first end wall 512 by a distance of 0.1 inches. The distance, wherein the line 546 furthest from the first end wall 512 is adjacent to the first row 546.

As shown, the slider 360 can have a block 550, a printed circuit board (PCB) 552, and a support frame 554. The block 550 can hold the printed circuit board 552 and selectively contact the printed circuit board 540 of the cradle 358 for measurement, which will be described later. Support frame 554 can be secured to block 550 to maintain block 550 and printed circuit board 552 in position on bracket 358.

The block 550 can have a raised portion 560 that can be secured to the rod 366. If desired, the raised portion 560 can have a threaded hole or other attachment feature to facilitate attachment of the rod 366 to the raised portion 560. Also, the block 550 can have a hole 562 that facilitates attaching the block 550 to the support frame 554. The printed circuit board 552 can have holes 564 that can be used to secure the printed circuit board 552 to the underside of the block 550 by using the fasteners 566 or the like.

The support frame 554 can have side panels with spaced apart apertures 568 to match the spacing of the apertures 562 of the block 550. Therefore, the support frame 554 can be fixed to the block 550 by inserting the lock 570 into the hole 568 of the support frame 554 and receiving the lock 570 into the hole 562 of the block 550. The lock 570 can be Screws, bolts or rivets. The support frame 554 can be secured to the block 550 and the tray 510 is attached between the bottom plate of the support frame 554 and the block 550. Therefore, as shown in Fig. 5A, the tray 510 (and the printed circuit board 540) can be grasped between the block 550 and the support frame 554.

The rod 366 can have a shaft 580 and a sleeve 582. The shaft 580 can have a shaft end 584 that facilitates attachment of the shaft 580 to the boss 560 of the block 550 and to the second link 364. The sleeve 582 can have a central passage 586 that can be designed to receive the shaft 580. The sleeve 582 can be sized such that the spring 368 can wrap around and match the exterior of the sleeve 582.

Please refer to FIG. 5C, which is a plan view showing the printed circuit board 552 of the slider 360 of the displacement measuring device 310 shown in FIGS. 3A and 3B. As shown, printed circuit board 552 can have conductive contacts 590 arranged in a row along the width of printed circuit board 552. The number of conductive contacts 590 can be the same as the number of conductive contacts 544 of each row 546 of printed circuit board 540. That is, each of the conductive contacts 590 can be in contact with one of the conductive contacts 544 of each of the rows 546 of the conductive contacts 544 of the printed circuit board 540 as the slider 360 moves along the printed circuit board 540.

Each of the electrically conductive contacts 590 and/or each of the electrically conductive contacts 544 can be coupled to a dedicated circuit that forms a closed circuit when the electrically conductive contacts 590 are in contact with the electrically conductive contacts 544. The closure of the circuit can be detected and recorded by circuitry on printed circuit board 540 and/or printed circuit board 552. The identification of the closed circuit can indicate which of the conductive contacts 544 of the printed circuit board 540 is in contact with one of the conductive contacts 590 of the printed circuit board 552, thereby indicating the position of the slider 360 on the carrier 358. Moreover, the displacement between the first connecting member 362 and the second connecting member 364 of the sensor 326 is also indicated, thereby indicating between the first coupling member 322 and the second coupling member 324 of the displacement measuring device 310. The displacement, in turn, indicates the displacement between the first end 202 and the second end 204 of the core member 200 of the building bracket 130.

The printed circuit board 540 and the printed circuit board 552 are selectively electrically connected together by wires or the like. Displacement measuring device 310 can have other components as shown and described in relation to displacement measuring device 110 of FIG. If desired, memory 144, input/output module 146, processor 148, power supply 150, and/or any other electronic component of displacement measuring device 110 of FIG. 1 can be disposed on printed circuit board 540 and/or printed circuit Board 552.

Preferably, the displacement measuring device 310 is capable of measuring the displacement change between the first end portion 202 and the second end portion 204 of the core member 200 within a relatively large displacement range, so that the displacement measuring device 310 can measure the building. Large deflection of the bracket 130. Also, in some embodiments, the displacement measuring device 310 can preferably provide an output in strained form in the building support 130. In this embodiment, the output of the displacement measuring device 310 can directly and unmodifiedly represent the strain in the building support 130.

Also, the displacement measuring device 310 can advantageously provide an output indicative of the absolute displacement of the first end 202 relative to the second end 204. More specifically, some displacement sensors only provide a change in position. The output of such a displacement sensor is highly dependent on the initial displacement. If the starting displacement changes without being measured, for example when supplying power to the displacement sensor, the measurement from that point may not be accurate. Advantageously, the displacement measuring device 310 can measure the absolute position. In particular, determining which of the conductive contacts 544 is in contact with one of the conductive contacts 590 provides an indication of displacement independent of any previous measurements made by the sensor 326. Since the displacement between the first end 202 and the second end 204 of the core member 200 can be received before or after the change, the sensor 326 can still provide an indication of the change in displacement, which can be displaced after comparison. Variety.

In some embodiments, the sensor 326 can be designed to be energized only if the displacement between the first end 202 and the second end 204 of the core member 200 changes significantly. For example, sensor 326 can have a sleep mode in which sensor 326 does not provide measurement data 142, and an active mode in which sensor 326 generates and records measurement data 142 as previously described. The sensor 326 can maintain a sleep mode under normal conditions. When a threshold displacement change or a threshold shift is detected between the first end 202 and the second end 204 of the core member 200, the sensor 326 can transition from the sleep mode to the active mode. For example, a threshold displacement can be selected such that once the building bracket 130 is secured to an adjacent building feature, the sensor 326 is unlikely to transition to the active mode until a deformation inducing event occurs.

In some embodiments (not shown), instead of threshold displacement, other measurements such as threshold acceleration may be used to switch sensor 326 from sleep mode to active mode. In this embodiment, an accelerometer or other second sensor can be coupled to the sensor 326 to provide a measure that can trigger the sensor 326 to transition from a sleep mode to an active mode.

Moreover, the displacement measuring device 310 can advantageously be easily resized in length to allow the displacement measuring device 310 to be easily adapted to building brackets 130 of different lengths. For example and in some embodiments, the first portion 332 of the housing 320, ie the second portion 334, can be made in various lengths. Similarly, bracket 358, rod 366, and spring 368 can all be made to different lengths. Some of these components can be fabricated through an extrusion process through which the various components can be fabricated to the desired length.

Moreover, the sensor 326 can be easily accommodated within the setback assembly 220 of the building support 130 in a manner similar to that shown in FIGS. 2A and 2B, in conjunction with the displacement measuring device 110. The sensor 326 can be housed in the housing 320 as shown and described above, and the housing 320 can protect the sensor 326 from intrusion of particulate matter from the cement layer 222 of the frustrating beam assembly 220. The receipt of the sensor 326 inside the setback assembly 220 can advantageously protect the sensor 326 from being protected during transport, storage, and/or installation of the building support 130.

Similar to the displacement measuring device 110, the displacement measuring device 310 can be coupled to an external device such as the computing device 120 of FIG. 1 to enable the computing device 120 to receive the measured data 142 and/or other data recorded by the sensor 326. , wherein the connection mode can be wired and/or wireless. In the case of a wired connection, the displacement measuring device 310 can have a connector (not shown), such as a USB or Ethernet connector, which can be adjacent to the first coupling 322 or the second coupling 324 An opening (not shown) in the housing 320 is achieved. Thus, such a connector can be passed through an aperture 234 in the end plate 232 of the housing 224 to achieve a connection (as shown in Figure 2B). Where wireless data connections are used, it may be preferred to transmit data through the frustration assembly 220 of the building support 130.

In an alternative embodiment, the displacement measuring device, such as displacement measuring device 110 or displacement measuring device 310, can be coupled to building bracket 130 in a different manner. For example, the displacement measuring device 110 or the displacement measuring device 310 can be disposed outside of the cement layer 222 of the building support 130 and/or outside of the setback assembly 220. Examples of such embodiments are shown and described in conjunction with Figures 6 and 7.

Referring to FIG. 6, a perspective view of a displacement measuring device 610 for measuring displacement in a building bracket 630 is shown in accordance with some embodiments, wherein the displacement measuring device 610 penetrates a peripheral portion of the building bracket 630. Displacement measuring device 610 optionally has a configuration similar to displacement measuring device 310 and/or displacement measuring device 110.

As shown, the building bracket 630 can have a configuration similar to the building bracket 130, wherein the core member 200 has a first end 202 and a second end 204, and a setback assembly 620 that resists bending of the core member 200, frustrating The flexing assembly 620 can have a cement layer (not shown) that prevents the core member 200 from bending and an outer casing 624 that positions the cement layer.

The displacement measuring device 610 can be threaded through the ridge 640 in the outer casing 624 rather than through the interior of the cementitious layer. The ridge 640 is optionally isolated from the cement layer, for example, through a metal wall (not shown) of the outer casing 624 to isolate the ridge 640 from the remaining space in the housing 624. In this case, since the metal walls and ridges 640 can cooperate to isolate the displacement measuring device 610 from the intrusion of particulate matter, the displacement measuring device 610 may not require a housing 250 and displacement similar to the displacement measuring device 110. The housing of the housing 320 of the device 310.

In the alternative, the metal wall may not be provided, and instead, the displacement measuring device 610 may be adjacent and/or in contact with the cement layer in the interior of the outer casing 624. In this case, the displacement measuring device 610 may preferably have a housing (not shown) such as the housing 250 of the displacement measuring device 110 and/or the housing 320 of the displacement measuring device 310.

The displacement measuring device 610 is coupled to the first end portion 202 and the second end portion 204 of the core member 200 via the extending arm 650 or, more specifically, to the first end portion 202 and the second portion The device 204 of the end 204 is anchored. Accordingly, the displacement measuring device 610 can measure the change in displacement between the first end 202 and the second end 204 in a manner similar to the displacement measuring device 110 and/or the displacement measuring device 310. Ridge 640 can be used to protect displacement measurement device 610 during storage, transportation, and/or installation of building bracket 630.

Referring to FIG. 7, a perspective view of a displacement measuring device 710 for measuring displacement in a building bracket 730 is shown, wherein the displacement measuring device 710 is passed along the edge of the building bracket 730. Displacement measuring device 710 optionally has a configuration similar to displacement measuring device 310 and/or displacement measuring device 110. As shown, the building bracket 730 can have a configuration similar to the building bracket 130, wherein the core member 200 has a first end 202 and a second end 204, and a setback assembly 720 that resists bending of the core member 200, frustrating The flexing assembly 420 can have a cement layer (not shown) that prevents the core member 200 from bending and an outer casing 724 that positions the cement layer.

The displacement measuring device 710 can be disposed adjacent to the outer casing 724 and parallel to the building support 730 rather than through the interior of the cementitious layer. The displacement measuring device 710 can optionally be in contact with the housing 724 or can be offset some distance from the housing 724. The displacement measuring device 710 can preferably have a housing 740 that is similar to the housing 250 of the displacement measuring device 110 and/or the housing 320 of the displacement measuring device 310. Although the displacement measuring device 710 can prevent the intrusion of particulate matter from the cement layer through the advantages of the outer casing 724, the housing 740 of the displacement measuring device 710 can further assist in the internal components of the displacement measuring device 710 with other solid materials (eg, The dust is isolated, otherwise the solid matter will interfere with the operation of the displacement measuring device 710.

The displacement measuring device 710 can be coupled to the first end 202 and the second end 204 of the core member 200 by the extension arm 750 through the use of the locking member 262 and/or the locking member 762, or more specifically, to the first The device anchors 210 of the end portion 202 and the second end portion 204. Accordingly, the displacement measuring device 710 can measure the change in displacement between the first end 202 and the second end 204 in a manner similar to the displacement measuring device 110 and/or the displacement measuring device 310.

After the building bracket 730 has been fabricated and/or attached to the building element, the positioning of the displacement measuring device 710 adjacent to the building bracket 730 can facilitate attachment of the displacement measuring device 710 to the building bracket 730. Thus, the displacement measuring device 710 can be retrofitted to an existing building support that has been installed in a building.

In some embodiments, the displacement measuring device 810 can be mounted similar to the displacement measuring device 110 or the displacement measuring device 310 and used to measure the displacement caused by strain in the building support, such as Figure 2A. And the building bracket 130 of Figure 2B.

However, the seal need not be hermetic, but may only be sufficient to substantially prevent solid matter from entering the cavity 826 to prevent such solid matter from interfering with the operation of the displacement sensor 818. Housing 812 can include a plurality of components as shown in Figures 8A, 8B, and 8C that can help achieve components within housing 812. Alternatively, in some embodiments, the housing 812 can be integrally formed as a single, unitary component.

In some embodiments, the first coupling member 814 and the second coupling member 816 can be configured to be fixed to an end of the core member of the building bracket, such as the first end portion 202 and the second portion of the core member 200 of the building bracket 130.

In some embodiments, the displacement sensor 818 can include a printed circuit board (PCB) 832 located in the housing 812. In some embodiments, printed circuit board 832 can be secured to second portion 822 of housing 812 using screws 828, bolts, nuts, or any other suitable coupling mechanism. In some embodiments, printed circuit board 832 can include or correspond to printed circuit board 540 as shown in FIG. 5B in accordance with some embodiments.

In some embodiments, the ends of the rods 834 are coupled to the housing 812 in an interference fit. In some embodiments, the shafting can have a threaded end that facilitates attachment of the shaft to the bore 838. In some embodiments, the shafting can be coupled to the housing 812 by an adhesive or epoxy. In some embodiments, the rod 834 can be oriented along an axis 840 that can correspond to the axis 500.
