Description

Technical Field

[0001] The invention belongs to the technical field of floor slab construction, and in particular, relates to a device and method for controlling the thickness of a concrete floor slab. Background Art

[0002] During the construction of the main structure, the thickness of the floor slab has always been the focus of quality control and is more related to the safety of the overall structure. During the construction process, due to the large span of the floor slab, the thickness of the floor slab around the sides will not meet the requirements, and a concave area will be formed in the middle of the floor slab, which will eventually affect the cumulative difference of the floor slab beyond the specification requirements, and seriously cause quality accidents. In the past, the thickness of the floor slab was controlled by measuring with a ruler or pre-embedded steel bar heads. Such methods have poor feasibility in actual operation and are prone to cause poor quality of concrete surface molding in actual operation.

[0003] For example, Chinese patent publication number CN111236655A discloses a floor thickness control tool, which is manufactured by screwing the locking nut A at the upper end of the inverted truncated cone-shaped fixing piece along the lower end of the fixing screw until the locking nut A at the upper end of the inverted truncated cone-shaped fixing piece is screwed over the lower end of the fixing screw, and then lifting the inverted truncated cone-shaped fixing piece. However, it is necessary to apply force from bottom to top when removing it, which is inconsistent with conventional construction operations. Usually, construction operations tend to apply force from top to bottom, and applying force from bottom to top may cause the tool to slip and cause injury to the operator. For example, Chinese patent announcement number CN110145126B discloses a floor thickness control pad, including a base, a retractable positioning structure and an indicator column. An installation groove and a first positioning groove are provided on the base. The installation groove extends in the vertical direction. The cross-section of the installation groove is the same in shape and size as the cross-section of the indicator column. However, the base is not fixed in position and shifts during the pouring of the floor slab, which will cause the position of the indicator column to be inaccurate, affecting the control of the floor thickness. Therefore, a device and method for controlling the thickness of a concrete floor slab which can control the thickness of the floor slab more stably are designed. Summary of the invention

[0066] Embodiment 1

[0067] See attached Figure 1-8 As shown, the present invention provides a technical solution: a concrete floor thickness control device, comprising a base 100 and a pad 200, the pad 200 is arranged at the upper end of the base 100, the pad 200 comprises a plurality of splicing blocks 201 and a bottom block 202, the splicing block 201 is arranged at the upper end of the bottom block 202;

[0068] The connection structure 300 is arranged on the cushion block 200. The connection structure 300 includes a fastening plate 301, a fixing block 302 and a screw 304. One end of the fastening plate 301 is fixed to the inner side of the fixing block 302. The screw 304 is threadedly matched with the fixing block 302.

[0069] The anti-vibration structure 400 is arranged between the connection structure 300 and the cushion block 200. The anti-vibration structure 400 includes an outer spring 401, a mounting sleeve 402, a fixing sleeve 403, a piston rod 404 and an inner spring 406. The outer spring 401 surrounds the outer side of the mounting sleeve 402, the mounting sleeve 402 is sleeved on the outer side of the fixing sleeve 403, the fixing sleeve 403 is sleeved on the outer side of the piston rod 404, and the inner spring 406 is arranged between the piston rod 404 and the fixing sleeve 403;

[0070] The device detection system, the device monitoring system 600 is used to monitor the status of the thickness control device in real time and make adjustments during the concrete vibration process.

[0071] The embodiment of the present invention is also implemented through the following technical solutions.

[0072] In an embodiment of the present invention, an adjustment structure 500 is also included. The adjustment structure 500 is arranged between the splicing block 201 and the bottom block 202. The adjustment structure 500 includes an adjustment rod 501, a fixing seat 503 and a control rod 504. The adjustment rod 501 is designed as a threaded rod. The interior of the cushion block 200 is provided with an adjustment groove 502 that is threadedly matched with the adjustment rod 501. The interior of the base 100 is provided with an installation groove 101 that is adapted to the bottom block 202. The interior of the installation groove 101 is fixed with a fixing seat 503 that is adapted to the adjustment rod 501, and the control rod 504 is plugged into the adjustment rod 501.

[0073] Specifically, the number of splicing blocks 201 is designed according to the height of the floor bottom reinforcement 700. The bottom block 202 is first installed at the bottom position close to the adjusting rod 501, and then the splicing blocks 201 are installed in sequence. The adjusting rod 501 is selected to be 10-20 cm higher than the height of the floor bottom reinforcement 700. When it is necessary to make a fine height adjustment of the splicing block 201, the staff inserts the control rod 504 into the upper end of the adjusting rod 501. By rotating the control rod 504, the adjusting rod 501 rotates in the thread of the fixing seat 503. Since the adjusting rod 501 is engaged with the splicing block 201 and the bottom block 202 through threads, the rotation of the adjusting rod 501 will cause the splicing block 201 and the bottom block 202 to move up and down along the length direction of the adjusting rod 501. With a one-way thread, the rotation of the adjusting rod 501 will cause the splicing block 201 and the bottom block 202 to move in the same direction (i.e., rise or fall together). If a two-way thread is used, the rotation direction of the adjusting rod 501 will determine the moving direction of the splicing block 201 and the bottom block 202 (i.e., rise in one direction and fall in the other direction). The design of multi-segment threads can achieve segmented control, allowing more precise adjustment within different height ranges. An elastic washer is provided between the adjusting rod 501 and the splicing block 201 and the cushion block 200. The elastic washer is fixed between the thread gaps of the adjusting rod 501. While keeping the splicing block 201 stable, the adjusting rod 501 is allowed to be fine-tuned. The elastic washer can absorb vibration, reduce noise, and provide a certain buffering effect.

[0074] Furthermore, the fixing seat 503 is installed inside the base 100 and used as a nut. Its internal thread cooperates with the external thread of the adjusting rod 501, and there is a gap between the fixing seat 503 and the inner bottom of the base 100. The gap allows the bottom end of the adjusting rod 501 to extend into the base 100 to achieve the purpose of adjusting the height. The adjusting rod 501 is rotated to rise or fall in the thread of the fixing seat 503 to perform adjustment. The fixing seat 503 is installed inside the base 100 as a nut. Its internal thread cooperates with the external thread of the adjusting rod 501 to fix and limit the position of the adjusting rod 501. The adjusting rod 501 can rotate freely in the thread of the fixing seat 503 through the gap without interfering with the bottom of the base 100.

[0075] In an embodiment of the present invention, the bottom block 202 is connected to the base 100 by screws, and the splicing block 201 is a horizontal "Z" design. The design of the splicing block 201 facilitates the installation of the floor bottom reinforcement 700 in its recessed position. The shape of the splicing block 201 is not limited to the aforementioned design, and is adaptively adjusted according to needs. The upper end of the bottom block 202 is adapted to the splicing block 201, and the upper surfaces of the splicing block 201 and the base 100 are provided with mounting holes 102 that are threadedly matched with the mounting sleeve 402, and the mounting holes 102 facilitate the installation of the connecting structure 300.

[0076] In an embodiment of the present invention, the mounting sleeve 402 is composed of two cylinders and a connecting block 407 for connection. The two cylinders are threadedly matched with the connecting block 407, so the connecting block 407 is made of rubber. The fixed cylinder 403 is fixed to the inner upper end of the mounting sleeve 402 and passes through the connecting block 407. The piston rod 404 is movably connected to the fixed cylinder 403. A damping ring 405 is arranged between the bottom end of the fixed cylinder 403 and the mounting sleeve 402. The damping ring 405 is fixed to the inside of the mounting sleeve 402, and the piston rod 404 passes through the damping ring 405 and is movably connected to the mounting sleeve 402. The two ends of the inner spring 406 are respectively fixedly connected to the fixed cylinder 403 and the damping ring 405, and surround the outside of the piston rod 404. The two ends of the outer spring 401 are screwed to the mounting sleeve 402.

[0077] Specifically, the fixing cylinder 403 and the piston rod 404 are covered inside by the connecting block 407 and two cylinders, and the vibration-proof structure 400 is installed at the bottom of the fastening plate 301 by installing the sleeve 402, and is placed between the connecting structure 300 and the splicing block 201. When the concrete is vibrated, the force of the floor bottom reinforcement 700 connected to the connecting structure 300 will be transmitted to the vibration-proof structure 400, and the first-level vibration reduction is performed through the outer spring 401, and the piston movement is performed synchronously through the fixing cylinder 403 and the piston rod 404 in the upper cylinder. Based on the material of the connecting block 407, the connecting block 407 is squeezed to perform the second-level vibration reduction, and the fixing cylinder 403 squeezes the inner spring 406 synchronously to perform the third-level vibration reduction, so as to reduce the vibration force caused by the vibration, and ensure the stability of the connection between the connecting structure 300 and the floor bottom reinforcement 700. The connecting block 407 is made of rubber material that can be used as damping, and the inner and outer springs 401 are prevented from being in a state of continuous jumping through the connecting block 407 and the damping ring 405.

[0078] In an embodiment of the present invention, the fastening plate 301 is made of an elastic alloy material, a buckle plate 303 is arranged between the fixed block 302 and the fastening plate 301, the fixed plate and the buckle plate 303 are connected, the buckle plate 303 and the fixed block 302 are of an integrated design, the buckle plate 303 is placed on the outer side of the other end of the fastening plate 301, the fastening plate 301 and the buckle plate 303 are movably connected, and the inner screw of the fastening plate 301 is connected with a spring piece 308.

[0079] In an embodiment of the present invention, a plurality of thread teeth 305 are arranged on the outer side of the screw rod 304, and a limiting plate 306 is arranged between adjacent thread teeth 305. The cross-section of the limiting plate 306 is designed to be "T" shaped, and is fixedly connected to the screw rod 304. The limiting plate 306 is made of rubber material, and a plurality of limiting grooves 307 adapted to the limiting plate 306 are opened on the surface of the fastening plate 301.

[0080] Specifically, due to the material of the fastening plate 301, the other end (movable end) that is not fixed on the fixing block 302 can be bent and inserted into the inner side of the buckle plate 303, and wrapped around the outer side of the floor bottom reinforcement 700. After the fastening plate 301 is tightly attached to the floor bottom reinforcement 700, the screw 304 is screwed into the fixing block 302, and the limiting plate 306 on the screw 304 is squeezed until the limiting plate 306 and the limiting groove on the fastening plate 301 are locked. Corresponding to 307, the limit plate 306 pops out from the limit groove 307, jams the fastening plate 301, and improves the firmness of the connection between the connecting structure 300 and the floor bottom reinforcement 700 through the force of the spring piece 308. When disassembly is required, the screw 304 is unscrewed, the limit plate 306 is squeezed and separated from the fastening plate 301, the fastening plate 301 is pulled out, the fastening plate 301 is loosened, the floor bottom reinforcement 700 is separated, and the control device is separated from the floor bottom reinforcement 700.

[0081] In an embodiment of the present invention, the device monitoring system 600 includes a level monitoring module 601, a distance measurement module 602, a displacement monitoring module 603, a laser scanning module 604, a distributed sensor network 605, a big data analysis module 606, a scene virtualization module 607 and a prompt module 608;

[0082] The level monitoring module 601 uses a level meter to monitor the level data of the control device and the floor slab bottom reinforcement 700, and is fixed on the base 100;

[0083] The distance measurement module 602 uses an ultrasonic distance meter or a laser distance meter to monitor the distance between the control devices, and the thickness between the vertical position of the control device and the bottom reinforcement 700 of the floor slab;

[0084] The displacement monitoring module 603 uses a high-precision displacement sensor to monitor the micro-displacement data of the control device and is fixed on the base 100 or the pad 200;

[0085] The laser scanning module 604 is used to scan the floor slab reinforcement 700 data to generate a three-dimensional image;

[0086] The distributed sensor network 605 is used to transmit the data of the control device and the floor slab 700 in real time, by deploying sensor nodes on the control device and the floor slab 700, and using the wireless sensor network to perform wireless network data transmission;

[0087] The big data analysis module 606 is used to process and analyze the monitoring data from multiple control devices, generate data change trends, and set an API interface to allow data interaction between the device monitoring system 600 and the big data analysis module 606;

[0088] The scene virtualization module 607 uses VR technology to provide a scene simulation of concrete floor pouring;

[0089] The prompt module 608 is used to provide sound and light prompts to the staff when abnormal data is detected.

[0090] In the embodiment of the present invention, the detailed steps of data analysis performed by the big data analysis module 606 are as follows:

[0091] Step 1: Establish a cloud server to receive monitoring data from the distributed sensor network 605;

[0092] Step 2: Perform conventional preprocessing operations on the received data and perform normalization processing;

[0093] Step 3: Use the time series model to analyze the changing trend of the data;

[0094] Step 4: Use clustering algorithms to analyze the data to find patterns in prediction errors and identify whether the data is abnormal.

[0095] The detailed clustering steps for step 4 are as follows:

[0096] Step 4a: Select an appropriate clustering algorithm, such as K-means, DBSCAN, etc., based on data characteristics and analysis objectives;

[0097] Step 4b, calculate the total error sum of squares under different cluster numbers, and select the point with the largest decrease in the total error sum of squares as the cluster number;

[0098] Step 4c, randomly select k data points as initial cluster centers, and assign each data point to the nearest cluster center based on the distance metric;
