Description
Technical Field
[0001] The present application relates to the technical field of strength detection of construction engineering formwork, and in particular to a device for detecting the support strength of construction engineering formwork. Background Art
[0002] During the construction process, the supporting strength of the construction formwork plays a vital role in ensuring the casting and forming of the concrete structure. In order to ensure the stability of the concrete structure casting, the supporting strength of the construction formwork is usually tested.
[0003] In the prior art, hydraulic push rods are usually used to apply extrusion force directly to the construction project formwork. Since the internal space of the casting mold formed after the construction project formwork is assembled is often relatively small, it is difficult for the horizontal and vertical hydraulic push rods to apply extrusion force to the construction project formwork inside the casting mold for detection. As a result, traditional construction project formwork strength detection devices often only focus on the detection of the support strength of a single piece of construction project formwork, ignoring the force characteristics and interaction relationship of the construction project formwork after assembly into a whole, making the detection results relatively simple and not comprehensive, which to a certain extent affects the staff's judgment on the support strength of the construction project formwork during actual construction.

[0015] Compared with the existing technology, the advantages of this application are: (1) The present application can fix a casting mold composed of multiple construction engineering templates on the bearing plate by fixing a bearing plate with a large number of evenly distributed threaded holes on the top of the base, and then install a rotatable and swingable first rod frame in the axle seat through a disc frame. Under the connection of the second rod frame, the driving force of the hydraulic push rod below can act on the construction engineering template from the inside to the outside through the sleeve in the narrow space of the casting mold under the principle of leverage, simulating the stress state of the construction engineering template during actual use, and then realizing the detection of the support strength of the construction engineering template by observing and detecting the deformation of the stressed construction engineering template and the casting mold.

[0022] The embodiments will be combined with the drawings in the specification to clearly and completely describe the technical solution of this application. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making any creative work shall fall within the scope of protection of this application. Example
[0023] The present invention provides a construction engineering template support strength detection device, please refer to Figure 1 - Figure 12, including a base 1, the top of the base 1 is fixedly covered with a bearing plate 101, and the top of the bearing plate 101 is provided with evenly distributed threaded holes, the base 1 and the bearing plate 101 are mounted with an axle seat 2, and a disc frame 201 is rotatably mounted in the axle seat 2, the top of the disc frame 201 is fixedly connected to a vertically arranged first rod frame 202, and a first connecting platform 203 is mounted on the first rod frame 202, the bottom of the disc frame 201 is fixedly connected to a second rod frame 204 located on the same vertical line as the first rod frame 202, and the second rod frame 204 A second connecting platform 205 is installed on it, a bearing seat 3 is fixedly connected to one side of the axle seat 2, and a horizontally arranged hydraulic push rod 301 is fixedly installed on the bottom of the bearing seat 3, and a connecting plate 302 connected to the second connecting platform 205 is fixedly installed on the telescopic end of the hydraulic push rod 301, a connecting seat 4 is fixedly installed on the side of the first connecting platform 203 close to the hydraulic push rod 301, and a horizontally arranged cross bar 401 is slidably inserted into the side of the connecting seat 4 away from the first connecting platform 203, and a pressure sensor 402 is installed between the connecting seat 4 and the cross bar 401.
[0024] When the device is in use, the staff can use the device to simulate the use environment of the construction engineering template after assembly, apply extrusion pressure on the inner side of the self-assembled construction engineering template, and realize the simulation detection of the strength of the construction engineering template. The staff assembles four mutually cooperating construction engineering templates into a casting mold connected on all sides, and fixes the casting mold assembled by the construction engineering template on the bearing plate 101 through the matching connection of bolts and numerous evenly distributed threaded holes on the bearing plate 101, and makes the first rod frame 202 be on the inner side of the formed casting mold, and then drives the connecting seat 4, cross bar 401 and sleeve 404 connected to the first connecting platform 203 to move through the swing of the first rod frame 202, and applies extrusion pressure to the construction engineering template from the inside, simulating the stress state of the construction engineering template during actual work, and realizing the detection of the supporting strength of the construction engineering template by observing and detecting the deformation of the stressed construction engineering template and the casting mold.
[0025] During the detection process, the hydraulic push rod 301 is powered on and started, and its telescopic end moves, and through the connection between the connecting plate 302 and the second connecting platform 205, it pushes the second rod frame 204 to swing to the left, driving the disc frame 201 to rotate, and then driving the first rod frame 202 to swing to the right, driving the connecting seat 4, cross bar 401 and sleeve 404 connected to the first connecting platform 203 to move to the right, applying extrusion force to the construction project template, and applying force on the inner side of the casting mold composed of multiple pieces of construction project templates, which can simulate the force conditions of the construction project template during actual use. The extrusion force is applied by the rotation of the first rod frame 202, simulating the force direction of the concrete in the casting mold acting on the construction project template, making the detection result more accurate. Under the relative action of force, the extrusion force applied to the construction project template will act in reverse on the pressure sensor 402 between the connecting seat 4 and the cross bar 401, and the extrusion force is monitored by the pressure sensor 402. With mutual cooperation, it is beneficial to improve the accuracy of the device in detecting the support strength of the construction project template.
[0026] See also Figure 6 and Figure 8 - Figure 10 When the cam 303 is in the upright position, the cam 303 is in the upright position, and the cam 303 is in the upright position, so that the cam 303 of the cam 303 is in the upright position.
[0027] See also Figure 4 and Figure 12, a transversely arranged cannula 403 is installed inside the end of the cross bar 401 away from the pressure sensor 402, and a sleeve 404 is provided on the outside of the end of the cross bar 401 away from the pressure sensor 402, and the sleeve 404 is fixedly connected to the end of the cannula 403 away from the cross bar 401, and the connecting seat 4 is connected to a first connecting pipe 405 connected to the interior of the cross bar 401, and the first connecting pipe 405 is connected to the cannula 403, and a first electrically controlled valve 406 is fixedly installed in the cannula 403. When the device is in use, when the connecting seat 4, the cross bar 401 and the sleeve 404 move and apply an extrusion force to the construction engineering template, the end of the sleeve 404 away from the cross bar 401 will contact the construction engineering template, and because the first rod frame 202 swings, the extrusion force is directed rightward and downward (with Figure 3 404 , and the like.
[0028] See also Figure 4, the cannula 403 is slidably inserted into the interior of the crossbar 401, and the sleeve 404 is movably sleeved on the outside of the crossbar 401. A hydraulic fixing mechanism is installed between the cannula 403 and the sleeve 404. The hydraulic fixing mechanism includes a chamber 407 formed between the crossbar 401, the cannula 403 and the sleeve 404. A second pipe 408 communicating with the interior of the chamber 407 is fixedly connected to the outer end wall of the sleeve 404, and a second electric control valve 409 is fixedly installed at the connection between the second pipe 408 and the chamber 407. When the device is used, due to the different internal dimensions of different casting molds after assembly, after the casting mold is fixed on the carrier plate 101, The distance between the inspected construction engineering template and the sleeve 404 is also different. In order to reduce the swing amplitude of the first rod frame 202 during the inspection process, the position of the sleeve 404 can be adjusted in advance. Since the sleeve 404 is movably sleeved on the outside of the cross bar 401, and the cannula 403 is slidably plugged into the inside of the cross bar 401, the sleeve 404 can be moved and extended relative to the cross bar 401. The outer end of the second connecting pipe 408 is connected to the hydraulic oil tank. When working, the staff can first control the first electric control valve 406 to close, and then the external air pump can supply high-pressure airflow to the cannula 403 through the first connecting pipe 405. Since the right end of the cannula 403 is connected to the second connecting pipe 408, the staff can first control the first electric control valve 406 to close, and then the external air pump can supply high-pressure airflow to the cannula 403 through the first connecting pipe 405. An electric control valve 406 is blocked, and the high-pressure air flow cannot be ejected outward through the right end of the cannula 403. At this time, under the push of the high-pressure air flow, the cannula 403 drives the sleeve 404 to move to the right relative to the cross bar 401, and finally the right end of the sleeve 404 contacts the construction engineering template. In this process, as the cannula 403 and the sleeve 404 move to the right relative to the cross bar 401, the space in the chamber 407 increases, and the second electric control valve 409 installed at the connection between the chamber 407 and the second connecting pipe 408 is in the open state. Under the action of the suction force, the hydraulic oil in the hydraulic oil tank connected to the second connecting pipe 408 enters through the second connecting pipe 408. When the sleeve 404 moves to the right and contacts the construction template, the second electrically-controlled valve 409 is closed. At this time, the hydraulic oil entering the chamber 407 can only be stored in the chamber 407. With the support of the hydraulic oil in the chamber 407, the sleeve 404 and the cross bar 401 maintain a relatively stable state, thereby locking the position of the sleeve 404. At this time, the extrusion force can be stably exerted on the construction template through the sleeve 404. In the process of applying the extrusion force, in order to ensure that the air flow layer can be stably formed between the sleeve 404 and the construction template, the staff can control the first electrically-controlled valve 406 to reopen.
[0029] When it is necessary to retract the position of the sleeve 404, the staff only needs to reopen the second electrically controlled valve 409 to reconnect the chamber 407 with the hydraulic oil tank connected to the second connecting pipe 408, and then close the first electrically controlled valve 406. Under the connection of the first connecting pipe 405, the cannula 403 is evacuated by an external air pump. Under the suction of the air flow, the cannula 403 drives the sleeve 404 to move to the left and reset, so that the internal space of the chamber 407 is reduced, and the internal hydraulic oil flows into the external hydraulic oil tank through the second connecting pipe 408. After the sleeve 404 moves to the appropriate position, the second electrically controlled valve 409 is closed again, and the hydraulic oil in the chamber 407 remains in a stable non-flowing state, the position of the sleeve 404 is re-fixed, and the first electrically controlled valve 406 is opened, and the external air pump stops the suction operation.
[0030] The device controls the opening and closing of the first electrically controlled valve 406 so that the first connecting pipe 405 can perform air filling and suction operations in the cannula 403. Combined with the locking of the hydraulic oil in the chamber 407 by the second electrically controlled valve 409 in the hydraulic positioning mechanism, the position of the sleeve 404 can be flexibly adjusted and controlled, so that the sleeve 404 can adaptively fit in the casting mold composed of different construction engineering templates, which can improve the flexibility and convenience of the actual operation of the device to a certain extent.
[0031] See also Figure 1 - Figure 3 、 Figure 5 and Figure 7 - Figure 8 A first longitudinal slot 102 is provided through the top of the base 1 and the middle position of the supporting plate 101, and the shaft seat 2 is slidably installed in the first slot 102. A first longitudinal guide rail 5 is fixedly installed inside the base 1, and the supporting seat 3 is slidably connected to the first guide rail 5. A first screw 501 parallel to the first guide rail 5 is rotatably installed in the base 1, and the first screw 501 is threadedly screwed with the supporting seat 3. A first servo motor 502 is fixedly installed on the base 1, and the driving shaft of the first servo motor 502 is connected to the first screw 501. When the device is in use, the shaft seat 2 is slidably installed in the first longitudinal slot 102 opened in the middle position of the base 1 and the supporting plate 101, so that the position of the first rod frame 202 in the shaft seat 2 can be longitudinally moved and adjusted, which is convenient for applying extrusion force to the construction project template at different longitudinal positions, which is conducive to improving the comprehensiveness and flexibility of the device during the detection process.
[0032] During the process of controlling the forward and backward movement of the shaft seat 2, the first servo motor 502 is powered on and started, driving the first screw 501 connected to its drive shaft to rotate synchronously, and with the help of the threaded connection between the first screw 501 and the supporting seat 3, the supporting seat 3 is driven to move forward and backward along the first screw 501. During the process of the supporting seat 3 sliding back and forth along the first guide rail 5, it will drive the shaft seat 2 to move forward and backward synchronously in the first slide groove 102, and then drive the first rod frame 202, the first connecting platform 203, and the connecting seat 4, cross bar 401 and sleeve 404 connected to the first connecting platform 203 to move forward and backward synchronously, thereby realizing the adjustment of the extrusion force application position, and the operation is flexible and stable.
[0033] See also Figure 3 、 Figure 5 and Figure 7 - Figure 9 The first connecting platform 203 is slidably mounted in the first rod frame 202, and a vertically arranged second screw rod 6 is rotatably mounted in the first rod frame 202, and the second screw rod 6 is threadedly screwed with the first connecting platform 203. A second servo motor 605 is fixedly mounted on the base 1, and a longitudinally arranged spline rod 601 is movably penetrated at the center position of the disc frame 201, and the spline rod 601 is rotatably mounted in the base 1, and the spline rod 601 is connected to the drive shaft of the second servo motor 605. A movable sleeve is rotatably mounted in the disc frame 201. The spline cylinder 602 is arranged on the outside of the spline rod 601, and the internal size of the spline cylinder 602 is adapted to the outer size of the spline rod 601. The first bevel gear 603 is fixedly mounted on the spline cylinder 602, and the lower end of the second screw 6 is fixedly mounted with a second bevel gear 604 that meshes with the first bevel gear 603. When the device is used, the staff can flexibly adjust the position height of the first connecting platform 203 according to actual detection needs, and then flexibly adjust the height of the extrusion force. When adjusting the position of the first connecting platform 203, the staff can adjust the position height of the first connecting platform 203 according to actual detection needs. When the height is high, the second servo motor 605 is powered on and started, driving the spline rod 601 connected to its drive shaft to rotate. During the rotation of the spline rod 601, the spline cylinder 602 sleeved on the outside thereof is driven to rotate, and then the first bevel gear 603 fixedly mounted on the end of the spline cylinder 602 is driven to rotate. With the meshing of the first bevel gear 603 and the second bevel gear 604, the rotational power is transmitted to the second screw 6. Driven by the threaded meshing of the second screw 6 and the first connecting platform 203, the first connecting platform 203 is moved up and down. The height adjustment is flexible and convenient to operate. The spline cylinder 602 is slidably sleeved on the outside of the spline rod 601. The internal size of the spline cylinder 602 is adapted to the external size of the spline rod 601, which makes the spline cylinder 602 only able to slide back and forth relative to the spline rod 601 and unable to rotate radially relative to the spline rod 601. During the rotation of the spline rod 601, the rotational power can be stably transmitted to the spline cylinder 602, avoiding the front and rear movement adjustment of the shaft seat 2 affecting the up and down lifting adjustment of the first connecting platform 203.
[0034] See also Figure 9 , a vertically arranged third screw rod 606 is rotatably installed in the second rod frame 204, and a third bevel tooth 607 engaged with the first bevel tooth 603 is fixedly installed on the top of the third screw rod 606, and the second connecting platform 205 is slidably installed in the second rod frame 204. The second connecting platform 205 is screwed with the third screw rod 606. Under the same length, the density of the thread on the third screw rod 606 is ten times that of the thread on the second screw rod 6. When the device is used, the second connecting platform 205 is screwed to the first connecting platform 203. The third screw 606 is rotatably mounted on the inner portion, and the second connecting platform 205 is screwed together by the third screw 606, so that the second connecting platform 205 can be moved up and down along the first connecting platform 203 to adjust its position. Since the upper end of the third screw 606 is fixedly mounted with a third bevel tooth 607 that meshes with the first bevel tooth 603, the spline rod 601 rotates to drive the second screw 6 to rotate. During the height adjustment process of the position of the first connecting platform 203, the third screw 606 can be driven to rotate synchronously to achieve the height adjustment of the second connecting platform 205. The synchronous lifting control is as follows: when the first connecting platform 203 moves upward for adjustment, the second connecting platform 205 moves downward for adjustment synchronously. The distance between the initial position of the first connecting platform 203 and the center of the disc frame 201 is equal to the distance between the initial position of the second connecting platform 205 and the center of the disc frame 201. Since the density of the threads on the third screw 606 is ten times that of the threads on the second screw 6, the distance moved by the first connecting platform 203 when the second screw 6 rotates one circle is ten times the distance moved by the second connecting platform 205 when the third screw 606 rotates one circle. By geometric conversion and lever prying, the device can set a sensor at the hydraulic push rod 301 to detect the extrusion force applied by the hydraulic push rod 301 during operation. After conversion, the extrusion force applied by the sleeve 404 on the construction engineering template can be calculated. The calculated extrusion force can be compared with the extrusion force actually collected at the pressure sensor 402 to avoid damage and error at the pressure sensor 402 due to long-term use, which can improve the detection accuracy of the device to a certain extent.

When the device is in use, the slidable support frame 702 is erected above the supporting plate 101, so that the device can not only perform simulation testing according to the working state of the construction engineering template during actual use, but also perform support strength testing on a single piece of construction engineering template. When testing a single piece of construction engineering template, the staff moves the position of the slide 701 along the second guide rail 7, so that the support frame 702 moves to a suitable position, close to the right end of the sleeve 404, and then the staff can tighten the connection between the slide 701 and the second guide rail 7 through bolts. The staff then locks the two support rods 703 to keep the position of the support frame 702 stable. The staff slides the two support rods 703 back and forth according to the size of the construction engineering template to be tested, adjusts the distance between the front and rear support rods 703 to match the size of the construction engineering template to be tested, and then firmly connects the support rods 703 and the support frame 702 with bolts to ensure that the position of the support rods 703 is stable. The construction engineering template to be tested is installed on the left side of the front and rear support rods 703, and the construction engineering template is supported by the two support rods 703. Then the staff starts the device and adjusts the force application position of the sleeve 404. The extrusion force is applied to the construction engineering template through the sleeve 404. The supporting strength of the construction engineering template is determined by observing the degree of deformation of the construction engineering template under force. The two detection modes are more flexible and diverse in operation, which is conducive to improving the comprehensiveness of detection.
[0036] The above is only the best implementation method adopted by this application in combination with current actual needs, but the scope of protection of this application is not limited to this.
