Description

Technical Field

[0001] The present invention relates to the technical field of building support, in particular to a multi-layer co-located synchronous support system and an operation method thereof. Background Art

[0002] With the large-scale construction of urban and rural buildings and the improvement of people's material and cultural living standards, due to the supporting needs of expanding the basements of existing residential buildings and underground parking lots in residential shopping malls, the development of underground space has shown a trend of increasingly deeper foundation burials and larger areas. As a result, the existing construction support technology cannot meet the requirements of existing basement space expansion, and the urgency of solving the support of the superstructure is becoming increasingly strong.

[0003] The traditional structural jacking support method mainly uses steel columns and jacks to manually adjust the jack support structure; the original support technology can only be used for local construction and cannot simultaneously support multiple layers. The construction period is long. The manual adjustment efficiency of this method is low, and the jacking pressure value cannot be controlled. Excessive pressure will crack the original structure and cause serious damage to the original structure. There are safety risks during the construction process, and structures with waterproofing requirements will later experience water seepage. Summary of the Invention

[0004] In response to the shortcomings of the existing technology, the present invention provides a multi-layer co-located synchronous support system and an operation method thereof, which can control the lifting pressure of the jack wirelessly, is easy to control, can be monitored in real time, and can improve construction efficiency.

[0005] In order to achieve the above object, the present invention is implemented through the following technical solutions: a multi-layer co-location synchronous support system, including a wireless induction jack; the wireless induction jack has a built-in wireless sensor, a control chip and a battery, and the control chip is used to process signal data and control work;

[0006] Positioning component: The positioning component is installed on the wireless induction jack and is used to locate the installation position of the wireless induction jack between each layer of structural components;

[0007] The control system has a built-in wireless receiving module, and the control system is used to receive the signal transmitted by the wireless sensor 11 or give it an operation command signal through the wireless receiving module, and applies an operation command to the wireless induction jack through the control chip 12.

[0008] The wireless sensor built into the wireless induction jack can be linked with the control system. The wireless sensor is wirelessly connected through the transceiver of the control system. The data information inside the wireless induction jack is transmitted to the control system through the control chip. In this way, data transmission and operation control are realized wirelessly, avoiding the traditional wiring method for control. In addition, multiple layers can be transmitted at the same time, eliminating a lot of wiring work and saving material and labor costs.

[0009] Preferably, steel pad linings are provided on both the upper and lower sides of the wireless induction jack. The steel pad linings are placed between the structural member and the wireless induction jack, increasing the stress area between the jack and the structural member. The surface is a rough surface, increasing the friction force, balancing the stress, protecting the original structural member from damage, and at the same time providing a stable and reliable support for the wireless induction jack.

[0010] Preferably, the positioning component includes high-strength magnets. High-strength magnets are sleeved on both the upper and lower ends of the wireless induction jack, and the high-strength magnets are attracted to the steel pad linings. The high-strength magnets have their own positive and negative poles, and are bonded to the lower end of the wireless induction jack with the positive pole facing up. Similarly, another high-strength magnet is bonded to the upper end of the wireless induction jack with the positive pole facing up. Setting high-strength magnets at both the upper and lower ends of the wireless induction jack can not only be used for precise positioning, but also be used to provide a certain attraction force, avoiding deviations in manual positioning and saving time and effort.

[0011] Preferably, an enhanced magnetic induction coil is also provided at the high-strength magnet. The enhanced induction coil is powered by a battery, and the battery is a rechargeable battery. Through power supply, the magnetic force of the high-strength magnet can be enhanced, making the connection and alignment of the wireless induction jacks up and down the floor more accurate and the connection more reliable.

[0012] The rechargeable battery provides a stable power source for the wireless inductor during operation. It can be charged when there is no power, and is more environmentally friendly and sustainable.

[0013] Preferably, an alarm indicator light and a spirit level are provided outside the wireless induction jack. The spirit level is provided with scales in both the horizontal direction and at the bottom. The external spirit level can visually adjust the verticality of the wireless induction jack through the scales at the bottom, and the spirit level has scales in the horizontal direction to monitor the displacement.

[0014] Preferably, a laser displacement sensor and a pressure sensor are also provided outside the wireless induction jack. The laser displacement sensor and the pressure sensor are respectively connected to the control chip. The pressure sensor measures the magnitude of the axial force of the jack, and the laser displacement sensor senses and measures the displacement distance and feeds it back to the control chip.

[0015] Preferably, the control system includes a one-key start button, a software model transfer interface, an operation display screen, a wireless induction signal indicator light, a comparison monitoring module, and a control processing module. The wireless induction signal indicator light is connected to the wireless receiving module, and the connection status can be displayed through the wireless receiving module; the software model transfer interface imports the corresponding data and is analyzed and processed by the control processing module. The comparison monitoring module is used to compare the pre-set standard data with the data fed back by the wireless induction jack and display it through the operation display screen.

[0016] The comparison and monitoring module can monitor displacement data, force measurement data, and other index data of the support system to ensure safety, and control abnormal changes during the jacking process according to the jacking pressure line, load line, and displacement line, and automatically adjust to achieve force balance.

[0017] By monitoring the displacement data of the jacks, it monitors whether the original structure has deflection. If the structure has a small displacement, it can be adjusted at any time. And by monitoring the force data of the jacks, it automatically jacks up to the final pressure value according to the data analysis results and automatically adjusts the jacking rate.

[0018] An operation method for a multi-layer in-situ synchronous support system comprises the following steps:

[0019] S1. Roughly locate the support points of the original structural beam and slab.

[0020] S2. Place steel cushion linings respectively on the upper and lower parts of each floor slab according to the point layout, and place high-strength magnets on the steel cushion linings respectively. Place a reinforced magnetic induction coil on one side of the high-strength magnet, and the two are magnetically attached together. Similarly, the steel cushion linings on the upper and lower parts of each floor slab are also magnetically attached together for positioning.

[0021] S3. Place wireless induction jacks on the upper part of the steel cushion linings, and the upper and lower ends of the wireless induction jacks are respectively sleeved in the high-strength magnets and the reinforced magnetic induction coils. Then observe the verticality through an external spirit level until the vertical state is adjusted.

[0022] S4. Place wireless induction jacks at the corresponding positions on each floor according to the above S3 step.

[0023] S5. Start the control system through a one-key start button, adjust the wireless receiving module to a favorable position for signal reception, debug and connect all the wireless induction jacks one by one. One wireless induction jack corresponds to one wireless induction signal indicator light until the wireless induction signal indicator light shows a successful connection.

[0024] S6. Import the original structure model information into the control system through a software model transfer interface, analyze and process it through a control processing module, and wirelessly transmit the data to the control chip 12, so as to control the wireless induction jacks to apply operation commands for automatic jacking. When the support force reaches the balance point and is displayed on the operation display screen, it can automatically stop and the support is completed.

[0025] S7. Cut off the columns at the bottom layer of the original structure, demolish the foundation, monitor the final support state through the comparison and monitoring module, and after ensuring safety, carry out basement excavation.

[0026] Preferably, in step S7, the comparison and monitoring module can online monitor the displacement data and pressure data of each wireless induction jack through the comparison and monitoring module. When the data is abnormal, the operation display screen will give a prompt. At the same time, the comparison and monitoring module sends a signal, and the alarm indicator light on the corresponding wireless induction jack will also give an alarm prompt, so that whether there is an abnormality can be quickly found and adjusted quickly.

[0027] Preferably, the software model transfer interface includes but is not limited to transferring the YJK or PKPM model. Through induction, the load data of the original structure is transmitted to the control system for analysis and processing. The axial force of each column can be identified, and the internal force of the jack on each layer can be accurately adjusted, which not only ensures safety but also ensures reasonable force and prevents secondary damage to the structure.

[0028] The beneficial effects of the present invention are as follows:

[0029] The control system uses a wireless signal to control the jack to achieve the jacking effect and support the original structure technology. Each layer is supported by a jack, so that the temporary conversion member on each layer only bears the load of this layer, and the safety of each layer can be guaranteed, thus ensuring the safety of the overall structure; it avoids the shortcoming that only the jack is set at the bottom layer in the traditional method, and the temporary conversion member at the bottom layer is extremely easy to be damaged.

[0030] The use of wireless sensors avoids the cumbersome wiring work, reduces the workload, reduces operation errors, improves the support efficiency, and expands the construction operation surface. The present invention has the advantages of fast construction, automatic control, high support efficiency, small damage to the original structure, and prevention of cracking of the original structure, creating great economic and social benefits.

Detailed implementation manners

[0037] In conjunction with the accompanying drawings, a better embodiment of the present invention will be described in further detail.

[0038] As Figures 1-5 A multi-layer in-situ synchronous support system includes a wireless induction jack 1 and a positioning component; the wireless induction jack 1 is internally provided with a wireless inductor 11, a control chip 12 and a battery 13, and the control chip 12 is used for processing signal data and controlling operations; steel gaskets 2 are arranged on both the upper and lower sides of the wireless induction jack 1, and the steel gaskets 2 are placed between the structural member and the wireless induction jack 1 to increase the force-bearing area between the jack and the structural member. The surface is a rough surface, which increases the friction force, balances the force, protects the original structural member from damage, and at the same time gives the wireless induction jack 1 a stable and reliable support.

[0039] The positioning component is installed on the wireless induction jack 1 and is used for positioning the installation position of the wireless induction jack 1 between each layer of structural members. The positioning component includes a high-strength magnet 3. High-strength magnets 3 are sleeved at both the upper and lower ends of the wireless induction jack 1, and the high-strength magnets 3 are attracted to the steel gaskets 2. The high-strength magnet 3 itself has positive and negative poles, and is bonded to the lower end of the wireless induction jack 1 with the positive pole facing upward. Similarly, another high-strength magnet 3 is bonded to the upper end of the wireless induction jack 1 with the positive pole facing upward. Arranging high-strength magnets 3 at both the upper and lower ends of the wireless induction jack 1 can not only be used for precise positioning, but also provide a certain attraction force, avoiding deviations in manual positioning and saving time and effort.

[0040] An enhanced magnetic induction coil 4 is also arranged at the high-strength magnet 3. The enhanced induction coil is powered by the battery 13. The battery 13 is a rechargeable battery 13. The rechargeable battery 13 provides a stable power source for the working wireless inductor 11. It can be charged when there is no power and is more environmentally friendly and sustainable; through power supply, the magnetic force of the high-strength magnet 3 can be enhanced, making the connection and alignment of the wireless induction jacks 1 up and down the floors more accurate and the connection more reliable.

[0041] An alarm indicator light 15 and a spirit level 14 are arranged outside the wireless induction jack 1. The spirit level 14 is provided with scales in both the horizontal direction and at the bottom. The external spirit level can directly adjust the verticality of the wireless induction jack 1 through the scales at the bottom, and the spirit level has scales in the horizontal direction to monitor the displacement.

[0042] Outside the wireless induction jack 1, there are also a laser displacement sensor 17 and a pressure sensor 16. The laser displacement sensor 17 and the pressure sensor 16 are respectively connected to the control chip 12. The laser displacement sensor 17 can adopt Keyence series sensors. The pressure sensor 16 measures the magnitude of the axial force of the jack, and the laser displacement sensor 17 accurately senses and measures the displacement distance and automatically feeds back the data to the control chip 12.

[0043] The wireless sensor 11 built into the wireless induction jack 1 can be linked with the control system 5. The wireless sensor 11 is wirelessly connected through the transceiver device of the control system 5. The data information inside the wireless induction jack 1 is transmitted to the control system 5 through the control chip 12. In this way, data transmission and operation control are achieved wirelessly, avoiding the traditional wiring method for control, and multiple layers can be transmitted simultaneously, saving a large amount of wiring work and saving material and labor costs.

[0044] The control system 5 is built with a wireless receiving module 52. The control system 5 includes a one-key start button 51, a software model transfer interface 54, an operation display screen 55, a wireless induction signal indicator light 53, a comparison monitoring module, and a control processing module. The wireless induction signal indicator light 53 is connected to the wireless receiving module 52, and the connection status can be displayed through the wireless receiving module 52. The software model transfer interface 54 imports corresponding data and analyzes and processes it through the control processing module. The comparison monitoring module is used to compare the pre-set standard data with the data fed back by the wireless induction jack 1 and display it through the operation display screen.

[0045] The comparison monitoring module can monitor displacement data, force measurement data, and other index data of the support system to ensure safety, and control abnormal changes during the jacking process according to the jacking pressure line, load line, and displacement line, and automatically adjust to achieve force balance.

[0046] By monitoring the displacement data of the jack, it is monitored whether the original structure has deflection. If the structure has a small displacement, it can be adjusted at any time. By monitoring the force data of the jack, it automatically jacks up to the final pressure value according to the data analysis result and automatically adjusts the jacking rate.

[0047] An operation method for a multi-layer in-situ synchronous support system includes the following steps:

[0048] S1. First, roughly locate the support points of the original structural beam and slab.

[0049] S2. Place steel shims 2 respectively on the upper and lower parts of each floor slab according to the point layout. Then, place high-strength magnets on the steel shims 2, and place enhanced magnetic induction coils 4 on one side of the high-strength magnets. The two are magnetically attached together. Similarly, the steel shims 2 on the upper and lower parts of each floor slab are also magnetically attached together for positioning.

[0050] S3. Place wireless induction jacks 1 on the upper part of the steel shims 2. The upper and lower ends of the wireless induction jacks 1 are respectively sleeved in the high-strength magnets 3 and the enhanced magnetic induction coils 4. Then, observe the verticality through an external spirit level 14 until the vertical state is adjusted.

[0051] S4. Place wireless induction jacks 1 at corresponding positions on each floor according to the steps in S3 above.

[0052] S5. Start the control system 5 through the one-key start button 51, adjust the wireless receiving module 52 to a favorable position for signal reception, and debug and connect all the wireless induction jacks 1 one by one. One wireless induction jack 1 corresponds to one wireless induction signal indicator light 53 until the wireless induction signal indicator light 53 shows a successful connection.

[0053] S6. Import the original structural model information into the control system 5 through the software model transfer interface 54, analyze and process it through the control processing module, and wirelessly transmit the data to the control chip 12, so as to control the wireless induction jacks 1 to issue operation commands for automatic jacking. When the supporting force reaches the balance point as shown on the operation display screen 55, it will automatically stop and the support is completed.

[0054] S7. Cut off the columns at the bottom layer of the original structure and demolish the foundation. Monitor the final support state through the comparison and monitoring module. The comparison and monitoring module can online monitor the displacement data and pressure data of each wireless induction jack 1 through the comparison and monitoring module. When the data is abnormal, the operation display screen 55 will give a prompt. At the same time, the comparison and monitoring module sends a signal, and the alarm indicator light 14 on the corresponding wireless induction jack 1 will also give an alarm prompt, so that any abnormality can be quickly detected and adjusted quickly. After ensuring safety, the basement excavation can be carried out.

[0055] The software model transfer interface 54 includes, but is not limited to, transferring the YJK or PKPM model. Through induction, the load data of the original structure is transmitted to the control system 5 for analysis and processing. The axial force of each column can be identified, and the internal force of the jack on each floor can be accurately adjusted, ensuring both safety and reasonable force, so that the structure will not be damaged secondly. For example, taking a ten-story residential structure as an example, the control system 5 identifies the calculation results of the original structure model. For example, the axial force at the bottom of the column on the bottommost floor is 10 kN, the axial force at the bottom of the column on the second floor is 9 kN... the axial force at the bottom of the column on the tenth floor is 1 kN. The wireless induction jack 1 on each floor is applied with the axial force at the bottom of the column corresponding to the corresponding floor through the control processing module.

[0056] The control system 5 of the present invention adopts the technology of using wireless signals to control the jacks to achieve the jacking effect and support the original structure. Each floor is supported by jacks, so that the temporary conversion member on each floor only bears the load of this floor, and the safety of each floor can be guaranteed, thus ensuring the safety of the overall structure; it avoids the disadvantage that only the jacks are set at the bottommost floor in the traditional method, and the temporary conversion member at the bottommost floor is extremely easy to be damaged.

[0057] The use of wireless sensors avoids the cumbersome wiring work, reduces the workload, reduces operation errors, improves the support efficiency, and expands the construction operation surface. The present invention has the advantages of fast construction, automatic control, high support efficiency, small damage to the original structure, and prevention of cracking of the original structure, creating great economic and social benefits.

[0058] The above embodiments are only used to explain the inventive concept of the present invention, rather than limiting the protection scope of the rights of the present invention. Any non-substantive modification of the present invention using this concept shall fall within the protection scope of the present invention.
