Description

Technical Field

[0001] This utility model belongs to the field of concrete testing technology, specifically relating to a testing device for accurately measuring the slump of concrete. Background Technology

[0002] Concrete is one of the most important building materials today. It is characterized by abundant raw materials, low price, and simple production process, so its usage is increasing. Concrete also has the characteristics of high compressive strength, good durability, and a wide range of strength grades. When using concrete, it is necessary to use a concrete slump tester to detect the slump of the concrete.

[0003] When testing the slump of concrete, the slump cone is placed on the base plate, and then concrete is poured into the slump cone in three batches. Then, a tamping rod is used to tamp the concrete layer from the edge to the center. After that, the concrete at the top of the slump cone is leveled, and then the slump cone is lifted vertically. The height difference between the concrete sample and the slump cone is measured to determine the slump of the concrete.

[0004] Currently, slump cone lifting is usually done manually. However, without the assistance of a guide and limiting mechanism, manual lifting of the slump cone is prone to errors, causing the concrete sample to be subjected to lateral or torsional forces, resulting in distorted slump shape and affecting the accuracy of the test. While using a drive mechanism such as a motor and hydraulic rod to lift the slump cone can overcome the errors caused by the lack of a guide mechanism, the slump cone needs to be installed on the drive mechanism with bolts and other fasteners. This results in a relatively cumbersome disassembly and reassembly process after each slump test to clean the slump cone and perform a second test, which affects the construction progress. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a stainless steel strip production arc straightening device.

[0006] The technical solution adopted to solve the above-mentioned technical problems is: to provide a detection device for accurately measuring the slump of concrete, characterized in that it includes: a base plate, the top surface of which is provided with a detection component for detecting the slump of concrete, the detection component including a first slump half-cylinder and a second slump half-cylinder placed on the base plate, the first slump half-cylinder and the second slump half-cylinder being combined to form a slump cylinder, a plurality of L-shaped clips being fixed on the side of the first slump half-cylinder near the second slump half-cylinder, a plurality of slots being opened on the side of the second slump half-cylinder near the first slump half-cylinder, the L-shaped clips being inserted into the inner wall of the slots from bottom to top, a guide square rod being fixed on the top surface of the base plate near the right side, a connecting frame being slidably provided on the outer wall of the guide square rod, the connecting frame being fixed to the side of the second slump half-cylinder away from the first slump half-cylinder, and a first fastening bolt being threadedly connected to the outer wall of the connecting frame.

[0007] Through the above technical solution, by inserting the first slump half-cylinder into the second slump half-cylinder from bottom to top to form a slump cylinder, the first slump half-cylinder remains locked in place with the second slump half-cylinder during the upward lifting process, which facilitates the quick disassembly and cleaning of the slump cylinder and speeds up the construction process. This installation method allows the second slump half-cylinder to be fixed to the base plate, which in turn can press and fix the first slump half-cylinder, preventing displacement and shaking of the slump cylinder when the concrete is being mixed. The guide rod guides the lifting of the slump cylinder, effectively preventing the concrete sample from being subjected to lateral or torsional forces, which could lead to a distortion of the concrete sample's collapse shape and affect the testing accuracy.

[0008] Furthermore, the L-shaped clip is interference-fitted with the slot, and the threaded end of the first fastening bolt abuts against the outer wall of the guide square rod.

[0009] The above technical solution increases the stability of the L-shaped clip and the slot by setting an interference fit connection. The first fastening bolt is used to fix the connecting frame, so that the first collapsed half cylinder and the second collapsed half cylinder are fixed.

[0010] Furthermore, a rotating square rod is rotatably connected to the top surface of the base plate near the rear side. A measuring rod is slidably mounted on the outer wall of the rotating square rod. A sliding seat is slidably mounted on the top surface of the measuring rod. A sliding hole is opened on the top surface of the sliding seat. A scale is slidably mounted inside the sliding hole. A second fastening bolt is threadedly connected to the outer wall of the measuring rod.

[0011] Using the above technical solution, a measuring rod is placed against the top of the slump cylinder to measure the height of the slump cylinder, while a ruler measures the height of the highest point of the collapsed concrete. The height difference between the measuring rod and the ruler can be used to accurately measure the slump of the concrete.

[0012] Furthermore, the threaded end of the second fastening bolt abuts against the outer wall of the rotating square rod, and a magnetic plate is fixed on one side of the inner wall of the sliding hole, which is magnetically attracted to the scale.

[0013] With the above technical solution, the measuring rod can be fixed at the same height as the collapse cylinder by the second fastening bolt, and the scale can be magnetically attracted by the magnetic absorbing piece to prevent the scale from sliding down due to gravity during measurement, thus affecting the measurement.

[0014] Furthermore, handles are fixed on both the front and rear sides of the outer wall of the first collapsed half-cylinder, and a funnel is movably fitted at the top of the collapsed cylinder formed by the merger of the first collapsed half-cylinder and the second collapsed half-cylinder.

[0015] The above technical solution allows workers to easily grip and lift the first collapsed half-cylinder by setting up a handle on it, thereby lifting the collapsed cylinder. The funnel design also facilitates workers to pour concrete into the collapsed cylinder.

[0016] Furthermore, a connector is fixed to the top surface of the base plate near the corners on the front and right sides, and a tamping rod is inserted into the connector.

[0017] The above technical solution, by setting up a tamping rod, makes it convenient for workers to tamp the concrete poured into the slump cone evenly, and the plug-in seat facilitates the storage of the tamping rod.

[0018] Furthermore, a rubber sleeve is fixedly fitted on the outer wall of the tamping rod, and a shovel head is fixed to the top of the tamping rod.

[0019] The above technical solutions increase the comfort of workers holding the tamping rod by using rubber sleeves, and the shovel head makes it easier for workers to remove excess concrete from the top of the slumping cylinder.

[0020] The beneficial effects of this utility model are as follows: By setting the collapse cylinder as a separable first collapse half-cylinder and a second collapse half-cylinder, and setting L-shaped locking strips and slots respectively, the first collapse half-cylinder is inserted into the second collapse half-cylinder from bottom to top. This ensures that the first collapse half-cylinder is always inserted and locked into the second collapse half-cylinder during the upward lifting process and will not separate. At the same time, it facilitates the quick disassembly, assembly and cleaning of the first and second collapse half-cylinders, and speeds up the construction process.

[0021] By fixing the second slump half-cylinder with the connecting frame, and connecting the first slump half-cylinder to the second slump half-cylinder in an upward insertion manner, the second slump half-cylinder can work with the base plate to press and fix the first slump half-cylinder, thereby effectively preventing the slump half-cylinder from shifting and shaking during the mixing of concrete, which would affect the accuracy of the test.

[0022] By setting the connecting frame to slide on the outer wall of the guide rod, the lifting of the slump cylinder is guided, effectively preventing the concrete sample from being subjected to lateral or torsional forces, which would cause the concrete sample to collapse in a distorted manner and affect the accuracy of the test.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] like Figure 1-4As shown, this embodiment of a detection device for accurately measuring concrete slump includes a base plate 1. A detection assembly for detecting concrete slump is provided on the top surface of the base plate 1. The detection assembly includes a first slump cylinder 2 and a second slump cylinder 201 placed on the base plate 1. The first slump cylinder 2 and the second slump cylinder 201 are combined to form a slump cylinder. Several L-shaped clips 202 are fixed to the side of the first slump cylinder 2 near the second slump cylinder 201, and several slots 20 are formed on the side of the second slump cylinder 201 near the first slump cylinder 2. 3. The L-shaped locking strip 202 is inserted into the inner wall of the slot 203 from bottom to top. By setting the collapse cylinder as a separable first collapse half cylinder 2 and second collapse half cylinder 201, and setting the L-shaped locking strip 202 and slot 203 respectively, the first collapse half cylinder 2 is inserted into the second collapse half cylinder 201 from bottom to top. This ensures that the first collapse half cylinder 2 is always inserted and locked into the second collapse half cylinder 201 during the upward lifting process and will not separate. At the same time, it facilitates the quick disassembly and cleaning of the first collapse half cylinder 2 and the second collapse half cylinder 201, and speeds up the construction process.

[0027] A guide rod 204 is fixed on the top surface of the base plate 1 near the right side. A connecting frame 205 is slidably installed on the outer wall of the guide rod 204. The connecting frame 205 is fixed to the side of the second collapse half-cylinder 201 away from the first collapse half-cylinder 2. By sliding the connecting frame 205 on the outer wall of the guide rod 204, the lifting of the collapse cylinder is guided, effectively preventing the concrete sample from being subjected to lateral force or torsion during the collapse and lifting process, which would cause the collapse shape of the concrete sample to be distorted and affect the detection accuracy.

[0028] The L-shaped clip 202 is interference-fitted with the slot 203. The outer wall of the connecting frame 205 is threaded with a first fastening bolt 206. The threaded end of the first fastening bolt 206 abuts against the outer wall of the guide rod 204. By setting the L-shaped clip 202 and the slot 203 to be interference-fitted, the stability of the L-shaped clip 202 and the slot 203 are increased. By rotating the first fastening bolt 206, its threaded end abuts against the outer wall of the guide rod 204, which can fix the connecting frame 205, thereby fixing the first slumped half-cylinder 2 and the second slumped half-cylinder 201. While fixing the second slumped half-cylinder 201 through the connecting frame 205, since the first slumped half-cylinder 2 is connected to the second slumped half-cylinder 201 by inserting from bottom to top, the second slumped half-cylinder 201 can cooperate with the base plate 1 to press and fix the first slumped half-cylinder 2, thereby effectively preventing the slumped cylinder from shifting and shaking when compacting concrete, which would affect the detection accuracy.

[0029] A rotating square rod 3 is rotatably connected to the top surface of the base plate 1 near the rear. A measuring rod 301 is slidably mounted on the outer wall of the rotating square rod 3. A sliding seat 302 is slidably mounted on the top surface of the measuring rod 301. A sliding hole 303 is opened on the top surface of the sliding seat 302. A scale 304 is slidably mounted inside the sliding hole 303. A second fastening bolt 305 is threadedly connected to the outer wall of the measuring rod 301. By rotating the rotating square rod 3, the measuring rod 301 is rotated to the location of the slump cone where the concrete has been poured. Slide the measuring rod 301 so that its bottom end abuts against the top of the slump cylinder, keeping the measuring rod 301 at the same height as the slump cylinder. Then rotate the square rod 3 to move the measuring rod 301 away from the slump cylinder. After pulling out the slump cylinder, reset the measuring rod 301 and slide the sliding seat 302 so that the scale 304 moves to the highest point of the collapsed concrete. Slide the scale 304 down to abut against the highest point of the concrete to measure the slump of the concrete accurately.

[0030] The threaded end of the second fastening bolt 305 abuts against the outer wall of the rotating square rod 3. A magnetic suction piece 306 is fixed on one side of the inner wall of the sliding hole 303. The magnetic suction piece 306 is magnetically attracted to the scale 304. By rotating the second fastening bolt 305 so that its threaded end abuts against the outer wall of the rotating square rod 3, the measuring rod 301 can be fixed at this height after it is kept at the same height as the collapse cylinder. The scale 304 can be magnetically attracted by the magnetic suction piece 306 to prevent the scale 304 from sliding down due to gravity during measurement, which would affect the measurement.

[0031] Handles 4 are fixed on both the front and rear sides of the outer wall of the first collapse half-cylinder 2. A funnel 401 is movably fitted on the top of the collapse cylinder formed by the merger of the first collapse half-cylinder 2 and the second collapse half-cylinder 201. By setting the handles 4 on the first collapse half-cylinder 2, it is convenient for workers to hold the handles 4 and lift the first collapse half-cylinder 2, thereby lifting the collapse cylinder. By setting the funnel 401, it is convenient for workers to pour concrete into the collapse cylinder.

[0032] A connector 5 is fixed on the top surface of the base plate 1 near the corners of the front and right sides. A tamping rod 501 is inserted into the connector 5. The tamping rod 501 facilitates the workers to tamp the concrete poured into the slump cylinder. The connector 5 also facilitates the storage of the tamping rod 501. A rubber sleeve 502 is fixedly fitted on the outer wall of the tamping rod 501. A shovel head 503 is fixed to the top of the tamping rod 501. The rubber sleeve 502 increases the comfort of the workers holding the tamping rod 501. The shovel head 503 makes it easy for the workers to remove excess concrete from the top of the slump cylinder.

[0033] The working principle of this embodiment is as follows: by sliding the first collapsed half-cylinder 2 from bottom to top with one side of the second collapsed half-cylinder 201, the L-shaped clip 202 is engaged with the slot 203. Then, the merged collapsed cylinder is placed on the top surface of the base plate 1. During this process, the outer wall of the connecting rod 205 and the guide rod 204 is slidably set. Then, the first fastening bolt 206 is rotated so that its threaded end abuts against the outer wall of the guide rod 204 to fix the connecting frame 205, thereby fixing the first collapsed half-cylinder 2 and the second collapsed half-cylinder 201. Rotate the square rod 3 so that the measuring rod 301 rotates to the slump cylinder where the concrete has been poured. Slide the measuring rod 301 so that the bottom end of the measuring rod 301 abuts against the top of the slump cylinder, keeping the measuring rod 301 at the same height as the slump cylinder. At this time, rotate the second fastening bolt 305 so that its threaded end abuts against the outer wall of the rotating square rod 3. After the measuring rod 301 is kept at the same height as the slump cylinder, fix the measuring rod 301 at this height. Then rotate the square rod 3 to move the measuring rod 301 away from the slump cylinder. At this time, pour concrete into the slump cylinder in three batches. Then remove the tamping rod 501 and use the tamping rod 501 to tamp the concrete from the edge of the concrete layer to the center. Then use the shovel head 503 to level the concrete at the top of the slump cylinder and then lift the slump cylinder vertically. At this time, the concrete will collapse naturally. At this point, reset the measuring rod 301 and slide the sliding seat 302 so that the scale 304 moves to the highest point of the collapsed concrete. Slide the scale 304 down to the highest point of the concrete to measure the slump of the concrete. Then the connecting frame 205 can be disassembled and the first collapsed half-cylinder 2 and the second collapsed half-cylinder 201 can be separated for cleaning.
