Description

Technical Field

[0001] The invention relates to the technical field of compressive strength detection devices, in particular to a compressive strength test device for construction waste recycled materials. Background Art

[0002] Domestic research on construction waste primarily focuses on the preparation and mix proportioning of recycled materials from construction waste, as well as their application in highway, loess foundation, and soft foundation treatment. This focus is on the development of equipment for separating construction waste, research into material mix proportions and particle size, and construction techniques and quality control during the construction process. Construction waste should be processed and sorted into brick aggregate and concrete aggregate. Brick aggregate can be used for roadbed filling, while concrete aggregate can be used for pavement base and subbase. Recycled aggregate, composed of concrete blocks, has significantly superior properties to natural aggregate and meets most road specifications for concrete aggregate. Therefore, it can be incorporated into flexible pavement base materials. As long as the recycled aggregate meets quality standards, it can be used as a base or subbase material, with performance comparable to that of natural aggregate as a base material. In hot-mix asphalt mixtures, recycled aggregate adheres to the surface of the hot asphalt, preventing precipitation, making it particularly suitable for hot-mix asphalt road construction projects. Hot-mix asphalt is used on most municipal roads in my country.

[0003] Concrete slabs made from recycled materials from construction waste usually need to be tested for compressive strength before use. The conventional testing method is to place the slab on a testing table and apply pressure to test its compressive strength. However, for recycled materials from construction waste, different mixing ratios may produce different effects. Therefore, repeated tests are required for different ratios. In actual operation, the slabs need to be prepared in advance and then placed on the testing table. After the test is completed, the slabs and their debris need to be removed, which is inefficient. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a compressive strength testing device for recycled materials from construction waste to solve the problems raised in the above-mentioned background technology.

[0006] Furthermore, two slide rails are fixed to the bottom of one side of the opening of the detection platform, a slide frame is fixed to the bottom of the collection frame, and the slide frame can be slidably buckled on the slide rails, and the top of the collection frame is flush with the bottom surface of the detection platform.

[0007] Furthermore, the prefabricated component also includes an insertion rod. Two insertion rods are fixed at the outer end of the collection frame, and the insertion rods are slidably inserted into the bottom of the placement frame. Slide grooves are opened on the bottom surfaces of both sides of the placement frame, and the bottoms of both ends of the first splint slide along the slide grooves.

[0008] Furthermore, slides are fixed at both ends of the second splint, and the slides slide along the outer surface of the first splint. The second splint is composed of two connecting plates and a bidirectional telescopic plate. Bolts are threadedly inserted on the surface of the slide and at the connection between the connecting plate and the extended end of the bidirectional telescopic plate.

[0009] Furthermore, plug-ins are slidably plugged into the tops of both sides of the placement frame, and contact blocks are fixed on the tops of the plug-ins. Springs are fixed on both sides of the bottom of the contact blocks, and the other ends of the springs are fixedly connected to the placement frame.

[0010] Furthermore, a first connecting rod is symmetrically connected to the bottom surface of the contact block through a rotating shaft, and the other end of the first connecting rod is rotationally connected to the first clamping plate through a rotating shaft. A second connecting rod is rotationally connected to the inner surface of the first clamping plate through a rotating shaft, and the other end of the second connecting rod is rotationally connected to the two side extended ends of the second clamping plate.

[0011] Furthermore, the pressure assembly also includes a cylinder, a cylinder is fixed at the bottom of the movable seat, the extended end of the cylinder is fixedly connected to the pressure plate, connecting frames are fixed on both sides of the top of the pressure plate, and a second electric push rod is fixed at the position of the connecting frame corresponding to the contact block.

[0012] Furthermore, a third screw rod is rotatably mounted on both sides of the detection platform through a bearing seat, a base is threadedly sleeved on the surface of the third screw rod, and the bottom of the vertical frame is fixed on the base.

[0013] Furthermore, the pushing assembly also includes a first screw rod, the first screw rod is rotatably installed inside the slide groove through a bearing, and the slide plate is threadedly sleeved on the surface of the first screw rod, and the first screw rod, the second screw rod and the third screw rod are all driven by a motor.

[0014] Furthermore, a first electric push rod is fixed on the top of the slide, and a socket is provided at the bottom of the front end of the insertion strip. The extended end of the first electric push rod can pass through the gap between the movable groove and the slot and be inserted into the socket.

[0015] Beneficial effects of the present invention:

[0016] 1. The present invention drives the vertical frame and the pressure plate to move forward and backward by the rotation of the third screw rod, and adjusts the position of the pressure plate so that the position of the connecting frame corresponds to the contact block. At this time, the center line of the pressure plate corresponds to the center line of the concrete slab inside the prefabricated component. When the cylinder drives the pressure plate to descend, the connecting frame descends at the same time. Because the connecting frame is L-shaped, according to the distance between the contact block and the connecting frame before the pressure plate contacts the concrete slab, the contact block is squeezed by the second electric push rod. Because the locking bolt is unlocked in advance, the first clamping plate and the second clamping plate are not fixed to each other. After the contact block is squeezed, the first connecting rod pushes the first clamping plate to both sides to release the clamping limit on the front and rear sides of the concrete slab. At the same time, the bidirectional telescopic plate of the second clamping plate extends, and as the first clamping plate moves, the second connecting rod drives the second clamping plate to move outward, releasing the clamping effect on the left and right sides of the concrete slab, avoiding interference with the detection of the compressive strength of the concrete slab.

[0017] 2. The present invention uses a bidirectional telescopic plate and a vertical plate of the second plywood to fix the connection with bolts. According to the size of the concrete slab to be prepared, a bidirectional telescopic plate of relative length is selected, that is, the extended ends of both ends of the bidirectional telescopic plate are fully retracted to ensure that the four sides of the concrete slab are flat. The bidirectional telescopic plate only plays a role when the limit is released. By sliding the first plywood along the slide groove and then fixing the slide to the outer surface of the first plywood with bolts, the first plywood and the second plywood can form a frame for preparing the concrete slab, and can also limit the concrete slab when it is sent to the inspection table to avoid the concrete slab from shifting.

[0018] 3. The present invention enables the bottom sliding frame of the collection frame to slide along the slide rail and be pushed toward one side of the inspection table. When the collection frame is aligned with the inspection table, the placement frame at the upper end is continued to be pushed, and the concrete slab is sent into the interior of the inspection table under the action of the placement frame, and the inserting strips on both sides of the placement frame are inserted into the slots, and the extended end of the first electric push rod on the top of the slide plate is inserted into the jack of the insert cylinder. Then the first screw rod drives the slide plate to slide along the moving groove, and the movement of the slide plate can assist the placement frame and the concrete slab to enter the interior of the inspection table, avoiding the inconvenience of manual handling. After the inspection is completed, the placement frame is also sent out by the drive of the first screw rod. During the compression test, the concrete slab may be broken. Because of the action of the first splint, the second splint and the wrapped placement frame, the debris stays inside the wrapped frame and can be pushed into the collection frame, avoiding residue on the inspection table and saving time for cleaning the inspection table.

[0019] 4. Compared with the prior art, the concrete slab of the present invention is located inside the prefabricated component for preparation and testing, which can save the time of transportation and fixation. At the same time, it can be used for testing slabs of different sizes. By pushing the component, the slab can be conveniently sent into the interior of the test bench and maintained in a corresponding position with the pressing plate, which is convenient for subsequent delivery and cleaning of the test bench, thereby improving the test efficiency.

A moving groove 41 is opened on the inner wall on both sides of the detection platform 1, and a slide plate 43 is installed in the moving groove 41. The detection platform 1 is provided with a slot 12 at the top of the moving slot 41, and the top of the moving slot 41 is connected to the slot 12. The positions of the slots 12 on both sides of the top of the placement frame 24 are fixed with insertion strips 27, and the insertion strips 27 can be slidably inserted into the slots 12. When using the device, a concrete slab 5 is prepared inside the prefabricated component 2 according to different ratios of recycled construction waste materials. The size of the concrete slab 5 can be adjusted. After the concrete slab 5 is formed, it is sent to the detection position through the sliding cooperation of the prefabricated component 2 and the detection platform 1. The surface of the concrete slab 5 is squeezed by the pressure component 3, and the compressive strength of the concrete slab 5 is detected according to the technical method in CN117433912A.

[0030] The top of the collection frame 21 is flush with the bottom surface of the inspection platform 1, and the prefabricated component 2 also includes an insertion rod 23. Two insertion rods 23 are fixed to the outer end of the collection frame 21, and the insertion rod 23 is slidably inserted into the bottom of the placement frame 24. The pushing component 4 also includes a first screw rod 42. The first screw rod 42 is rotatably installed inside the slide groove 29 through a bearing, and the slide plate 43 is threadedly sleeved on the surface of the first screw rod 42. The first screw rod 42, the second screw rod 32 and the third screw rod 38 are all driven by a motor. A first electric push rod 44 is fixed to the top of the slide plate 43. The front end bottom of the insertion strip 27 is provided with a socket 28. The extended end of the first electric push rod 44 can pass through the notch of the moving groove 41 and the slot 12 and be inserted into the socket 28. The prepared concrete slab 5 is placed on the slide rail 11 together with the prefabricated component 2. The bottom sliding frame 22 of the collecting frame 21 slides along the slide rail 11 and can be pushed toward the side of the testing table 1. When the collecting frame 21 is aligned with the testing table 1, the placing frame 24 at the upper end is continued to be pushed. The concrete slab 5 is sent into the interior of the testing table 1 under the action of the placing frame 24, and the inserting strips 27 on both sides of the placing frame 24 are inserted into the slots 12. The extended end of the first electric push rod 44 at the top of the slide plate 43 is inserted into the socket 28 of the insert cylinder. Then the first screw rod 42 drives the slide plate 43 to slide along the moving groove 41. The movement of the slide plate 43 can assist the placing frame 24 and the concrete slab 5 to enter the interior of the testing table 1, avoiding the inconvenience of manual handling. After the inspection is completed, the placing frame 24 is also sent out by the drive of the first screw rod 42. During the compression test, the concrete slab 5 may be broken. Because of the action of the first splint 25, the second splint 26 and the wrapped placing frame 24, the debris stays inside the wrapped frame and can be pushed into the collection frame 21, avoiding residue on the testing table 1 and saving time for cleaning the testing table 1.

[0031] In this embodiment, the bottom surfaces of both sides of the placement frame 24 are provided with sliding grooves 29, the bottoms of both ends of the first splint 25 slide along the sliding grooves 29, and the two ends of the second splint 26 are fixed with slides 213, and the slide 213 slides along the outer surface of the first splint 25, and the second splint 26 is composed of two connecting plates and a two-way telescopic plate. Bolts are threaded on the surface of the slide 213 and at the connection between the connecting plate and the extended end of the two-way telescopic plate. The top of both sides of the placement frame 24 is slidably plugged with plug-ins 215, and the top of the plug-in plate 215 is fixed with a contact block 210, and the bottom two sides of the contact block 210 are fixed with springs 216, and the other end of the spring 216 is fixedly connected to the placement frame 24, and the bottom surface of the contact block 210 is rotated by a rotating shaft. The first connecting rod 211 is symmetrically connected to the rotation, and the other end of the first connecting rod 211 is rotationally connected to the first clamping plate 25 through a rotating shaft. The second connecting rod 212 is rotationally connected to the inner surface of the first clamping plate 25 through a rotating shaft, and the other end of the second connecting rod 212 is rotationally connected to the extended ends on both sides of the second clamping plate 26. The pressure assembly 3 also includes a cylinder 34. The cylinder 34 is fixed to the bottom of the movable seat 33. The extended end of the cylinder 34 is fixedly connected to the pressure plate 35. Connecting frames 36 are fixed on both sides of the top of the pressure plate 35, and the second electric push rod 37 is fixed to the position of the connecting frame 36 corresponding to the contact block 210. The third screw rod 38 is rotatably installed on both sides of the detection platform 1 through the bearing seat, and the surface of the third screw rod 38 is threaded with a base 39 , and the bottom of the vertical frame 31 is fixed on the base 39. Through the rotation of the third screw rod 38, the base 39 drives the vertical frame 31 and the pressure plate 35 to move forward and backward, and adjusts the position of the pressure plate 35 so that the position of the connecting frame 36 corresponds to the contact block 210. At this time, the center line of the pressure plate 35 corresponds to the center line of the concrete slab 5 inside the prefabricated component 2. When the cylinder 34 drives the pressure plate 35 to descend, the connecting frame 36 also descends. Because the connecting frame 36 is L-shaped, according to the distance between the contact block 210 and the connecting frame 36 before the pressure plate 35 contacts the concrete slab 5, the contact block 210 is squeezed by the second electric push rod 37. Because the locking bolt 214 is unlocked in advance, the first clamping plate 25 and the second clamping plate 26 are not fixed to each other. After the contact block 210 is squeezed, the first connecting rod 211 pushes the first clamping plate 25 to both sides to release the clamping limit on the front and rear sides of the concrete slab 5. At the same time, the two-way telescopic plate of the second clamping plate 26 is extended, and as the first clamping plate 25 moves, the second connecting rod 212 drives the second clamping plate 26 to move outward to release the clamping effect on the left and right sides of the concrete slab 5. The movement range is not too large, and it is just a simple contact squeezing effect on the four sides of the concrete to avoid interference with the test of the compressive strength of the concrete slab 5. The two-way telescopic plate of the second clamping plate 26 and the vertical plate are fixedly connected by bolts. According to the size of the concrete slab 5 to be prepared as needed, the two-way telescopic plate of relative length is selected, that is, the extended ends at both ends of the two-way telescopic plate are fully retracted to ensure that the four sides of the concrete slab 5 are flat. The two-way telescopic plate only plays a role when the limit is released.By sliding the first clamping plate 25 along the slide groove 29 and then fixing the slide 213 to the outer surface of the first clamping plate 25 with bolts, the first clamping plate 25 and the second clamping plate 26 can form a frame for preparing the concrete slab 5. When the concrete slab 5 is placed on the inspection table 1, it can also limit the position of the concrete slab 5 to prevent it from shifting.

[0032] When using the device, a concrete slab 5 is prepared inside the prefabricated component 2 according to different proportions of recycled construction waste materials. The size of the concrete slab 5 can be adjusted, and the prepared concrete slab 5 is placed on the slide rail 11 together with the prefabricated component 2. The slide frame 22 at the bottom of the collection frame 21 slides along the slide rail 11 and can be pushed toward the side of the inspection table 1. When the collection frame 21 is aligned with the inspection table 1, the placement frame 24 at the upper end is continued to be pushed. The concrete slab 5 is sent into the interior of the inspection table 1 under the action of the placement frame 24, and the insertion strips 27 on both sides of the placement frame 24 are inserted into the slot 12. The extended end of the first electric push rod 44 at the top of the slide plate 43 is inserted into the socket 28 of the insert cylinder, and then the first screw rod 42 drives the slide plate 43 to slide along the movable groove 41, and the slide plate 43 can be used to The mobile auxiliary placement frame 24 and the concrete slab 5 enter the interior of the inspection table 1 to avoid the inconvenience of manual handling. After the inspection is completed, the placement frame 24 is sent out by the drive of the first screw rod 42. During the compression test, the concrete slab 5 may be broken. Because of the action of the first splint 25, the second splint 26 and the wrapped placement frame 24, the debris stays inside the wrapped frame and can be pushed into the collection frame 21 to avoid residue on the inspection table 1 and save time for cleaning the inspection table 1. Through the rotation of the third screw rod 38, the base 39 drives the vertical frame 31 and the pressing plate 35 to move back and forth, and adjusts the position of the pressing plate 35 so that the position of the connecting frame 36 corresponds to the contact block 210. At this time, the center line of the pressing plate 35 is aligned with the concrete slab 5 inside the prefabricated component 2 Corresponding to the center line of the concrete slab 5, when the cylinder 34 drives the pressing plate 35 to descend, the connecting frame 36 descends at the same time. Because the connecting frame 36 is L-shaped, according to the distance between the contact block 210 and the connecting frame 36 before the pressing plate 35 contacts the concrete slab 5, the contact block 210 is squeezed by the second electric push rod 37. Because the locking bolt 214 is unlocked in advance, the first clamping plate 25 and the second clamping plate 26 are not fixed to each other. After the contact block 210 is squeezed, the first connecting rod 211 pushes the first clamping plate 25 to both sides, releasing the clamping limit on the front and rear sides of the concrete slab 5. At the same time, the bidirectional telescopic plate of the second clamping plate 26 extends, and as the first clamping plate 25 moves, the second connecting rod 212 drives the second clamping plate 26 to move outward, releasing the clamping effect on the left and right sides of the concrete slab 5. , the movement range will not be too large, it is just a simple contact squeezing effect on the four sides of the concrete, avoiding interference with the test of the compressive strength of the concrete slab 5, the bidirectional telescopic plate of the second plywood 26 and the vertical plate are fixedly connected by bolts, and the bidirectional telescopic plate of relative length is selected according to the size of the concrete slab 5 to be prepared, that is, the extended ends of both ends of the bidirectional telescopic plate are fully retracted to ensure that the four sides of the concrete slab 5 are flat, and the bidirectional telescopic plate only plays a role when the limit is released. By sliding the first plywood 25 along the slide groove 29 and then fixing the slide 213 to the outer surface of the first plywood 25 by bolts, the first plywood 25 and the second plywood 26 can form a frame for preparing the concrete slab 5, and can also limit the concrete slab 5 when it is sent to the test table 1.To prevent the concrete slab 5 from deflecting, the pressure component 3 is used to press the surface of the concrete slab 5 to test the compressive strength of the concrete slab 5.
