Description

Technical Field

[0001] This utility model relates to the field of testing device technology, specifically to a concrete permeability assessment device for building testing. Background Technology

[0002] Concrete is a composite material formed by binding fine and coarse aggregates with cement and allowing it to harden over a period of time. In the past, lime-based cement, such as lime paste, was the most common, but hydraulic cement, such as calcium aluminate cement or silicate cement, is sometimes used. Non-cement-based concrete is different from other concretes in that it directly binds various aggregates together. Non-cement-based concrete includes asphalt concrete, which uses asphalt as a binder, and polymer concrete, which uses polymers as a binder. Asphalt concrete is often used for road surfaces.

[0003] In the research of concrete pouring technology, it is necessary to calculate the permeability of concrete. Traditional permeability assessment devices have a simple structure and low accuracy. At the same time, some current permeability assessment devices have insufficient sealing, making it easy for water to leak out, and are not conducive to later maintenance and replacement.

[0004] A prior art patent with publication number CN217132909U discloses a solution including a lifting structure, a clamping and fixing structure, a housing, and a mounting frame. The lifting structure includes a liquid storage cylinder with a threaded head fixed to its bottom end. A connecting plate is located at the bottom end of the liquid storage cylinder, with a connecting hole at its top. The bottom end of the threaded head passes through the connecting hole and is threadedly connected to a fixing nut. The threaded head has a hollow internal structure, and the liquid storage cylinder, the threaded head, and one side of the connecting plate are connected. A sealing plate is located at the bottom end of the connecting plate and is fixedly connected to the connecting plate. Multiple sets of concrete models are used for simultaneous testing to improve the accuracy of concrete permeability assessment. A motor drives two adjacent clamping plates to move inward, thereby fixing the concrete model. Assembly and disassembly are relatively simple.

[0005] Existing devices, including those mentioned above, have gradually revealed shortcomings in the technology with use, mainly in the following aspects:

[0006] First, existing concrete permeability testing devices can only test one side of a concrete block when conducting permeability tests. When it is necessary to test the permeability of the side of the concrete block, it is necessary to unfix the concrete block and turn it around, which is cumbersome and reduces the efficiency of testing the permeability of the concrete block in different directions.

[0007] Secondly, the existing method of using a screw to control two clamping blocks to hold the concrete block is limited by the hard contact between the clamping blocks and the concrete surface, which can easily cause the concrete block to break or crack, affecting the accuracy of the permeability test.

[0008] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0009] To address the shortcomings of existing technologies, this utility model provides a concrete permeability testing device for building inspection. This device solves the problem that traditional concrete permeability testing devices can only test one side of a concrete block. When it is necessary to test the permeability of the side of the concrete block, it is necessary to unfix the concrete block and turn it around, which is cumbersome and reduces the efficiency of testing the permeability of the concrete block in different directions.

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] A concrete permeability testing device for building applications includes a liquid collection base shell with an opening at its upper end. Inside the base shell are several directional adjustment seats arranged side-by-side, pivoting around a horizontal axis. Each directional adjustment seat has two clamping seats that slide in opposite directions. A base plate is horizontally fixed to the lower end of each of the two clamping seats. Buffer clamping plates are connected to the clamping surfaces of each clamping seat using elastic components.

[0012] A sliding frame is slidably provided above the liquid collection bottom shell. A liquid storage cylinder is vertically raised and lowered on the sliding frame corresponding to each of the direction adjustment seats. An on / off valve for controlling the flow of liquid is provided inside the liquid storage cylinder. A telescopic rubber sleeve is fixedly connected to the lower end of the liquid storage cylinder.

[0013] As an optimized solution, a downward pressure cylinder is vertically fixed to the upper end of the sliding frame corresponding to each of the liquid storage cylinders, and a mounting plate is fixed to the lower end of the downward pressure cylinder, with the upper end of the liquid storage cylinder fixed to the mounting plate.

[0014] As an optimized solution, the liquid storage cylinder is a transparent cylinder with graduation lines on its outer wall, and a filling cylinder that communicates with its inner cavity is fixedly connected to the outer wall of the liquid storage cylinder near the upper end.

[0015] As an optimized solution, the elastic component includes guide rods fixedly connected in parallel to the back of the buffer clamping plate. The clamping seat has a guide hole that matches the guide rod. The other end of the guide rod passes through the guide hole and is fixedly connected to a pull plate. A tension spring is fitted on the guide rod. The two ends of the tension spring are fixedly connected to the pull plate and the back of the clamping seat, respectively.

[0016] As an optimized solution, a rubber plate is fixedly attached to the clamping surface of the buffer clamping plate.

[0017] As an optimized solution, the sliding frame includes side frames arranged side by side on both sides of the liquid collecting bottom shell, a top frame fixed between the upper ends of the two side frames, rectangular guide rods fixed on the opposite side walls of the liquid collecting bottom shell, and rectangular guide holes matching the rectangular guide rods opened on the side frames.

[0018] As an optimized solution, a stop knob is threaded onto the side frame, and the end of the stop knob abuts against the rectangular guide rod.

[0019] As an optimized solution, the direction adjusting seat is rotatably equipped with a lead screw, which has two threaded sections with opposite directions of rotation. The two clamping seats are threadedly connected to the two threaded sections respectively.

[0020] As an optimized solution, two end seats are fixedly connected in parallel on the direction adjustment seat, and the two ends of the lead screw are rotatably mounted on the two end seats, with a drive motor for driving the lead screw to rotate fixedly connected to one of the end seats.

[0021] As an optimized solution, a guide rail is fixedly connected to the direction adjustment seat, and a guide groove matching the guide rail is opened at the lower end of the clamping seat.

[0022] As an optimized solution, a rotating shaft is rotatably installed between the relative inner walls of the liquid collecting bottom shell corresponding to each of the direction adjustment seats. The lower end of the direction adjustment seat is fixedly connected to the rotating shaft through a connecting plate. A drive gear is fixedly connected to each rotating shaft. A drive rack that meshes with several drive gears is horizontally slidably provided on the inner wall of the liquid collecting bottom shell.

[0023] As an optimized solution, an adjusting cylinder is fixedly connected to the outer wall of the liquid collecting bottom shell, and the telescopic end of the adjusting cylinder is fixedly connected to the end of the driving rack.

[0024] As an optimized solution, a guide seat is fixedly connected to the inner wall of the liquid collecting bottom shell, and the drive gear is slidably connected to the guide seat.

[0025] Compared with the prior art, the beneficial effects of this utility model are:

[0026] By driving the two clamping seats to slide relative to each other through the drive motor, the distance between the two clamping seats is adjusted, the concrete block is supported by the bottom support plate, the end of the concrete block is clamped by the buffer clamping plate, and the concrete block is clamped by the elasticity of the tension spring. This can prevent the clamping seats from rigidly contacting the concrete block in the traditional technology, prevent the concrete block from being broken or cracked, and ensure the accuracy of the concrete block permeability assessment.

[0027] Because the clamping seat is slidably connected to the direction adjustment seat, the drive rack is moved by the adjustment cylinder, and the drive rack uses the drive gear to drive the direction adjustment seat to swing, thereby turning the concrete block in a different direction. This eliminates the need to disassemble and fix the concrete block again, making it convenient and quick. Attached Figure Description

Several directional adjustment seats 3 are arranged side-by-side inside the liquid collection shell, pivoting around a horizontal line.

[0034] A sliding frame 2 is slidably provided above the liquid collection bottom shell. A liquid storage cylinder 21 is vertically raised and lowered on the sliding frame 2 corresponding to each direction adjustment seat 3. An on / off valve 24 for controlling the flow of liquid is provided inside the liquid storage cylinder 21. A telescopic rubber sleeve 25 is fixedly connected to the lower end of the liquid storage cylinder 21.

[0035] The upper end of the sliding frame 2 is vertically fixed to each liquid storage cylinder 21 with a pressing cylinder 20. The lower end of the pressing cylinder 20 is fixed to a mounting plate, and the upper end of the liquid storage cylinder 21 is fixed to the mounting plate.

[0036] The liquid storage cylinder 21 is a transparent cylinder with scale lines 22 on its outer wall. A liquid filling cylinder 23 that communicates with its inner cavity is fixedly connected to the outer wall of the liquid storage cylinder 21 near the upper end.

[0037] The elastic component includes a guide rod 8 that is fixedly attached to the back of the buffer clamping plate 7. The clamping seat 4 has a guide hole that matches the guide rod 8. The other end of the guide rod 8 passes through the guide hole and is fixedly attached to a pull plate 6. A tension spring 9 is fitted on the guide rod 8. The two ends of the tension spring 9 are fixedly attached to the pull plate 6 and the back of the clamping seat 4, respectively.

[0038] A rubber plate is fixed to the clamping surface of the buffer clamping plate.

[0039] The sliding frame 2 includes side frames arranged side by side on both sides of the liquid collecting bottom shell 1. A top frame is fixed between the upper ends of the two side frames. Rectangular guide rods 17 are fixed on the opposite side walls of the liquid collecting bottom shell 1. Rectangular guide holes matching the rectangular guide rods 17 are opened on the side frames.

[0040] A stop knob 18 is threaded onto the side frame, and the end of the stop knob 18 abuts against the rectangular guide rod 17.

[0041] The direction adjusting seat 3 is equipped with a lead screw 15, which has two threaded sections with opposite directions of rotation. The two clamping seats 4 are threadedly connected to the two threaded sections respectively.

[0042] Two end seats are fixedly connected in parallel on the direction adjustment seat 3. The two ends of the lead screw 15 are rotatably mounted on the two end seats, and a drive motor 5 for driving the lead screw 15 to rotate is fixedly connected to one of the end seats.

[0043] A guide rail is fixedly connected to the direction adjustment seat 3, and a guide groove matching the guide rail is opened at the lower end of the clamping seat 4.

[0044] A rotating shaft 11 is rotatably mounted between the inner walls of the liquid collecting bottom shell 1 and each direction adjustment seat 3. The lower end of the direction adjustment seat 3 is fixedly connected to the rotating shaft 11 through a connecting plate 19. A drive gear 12 is fixedly connected to each rotating shaft 11. A drive rack 13 that meshes with several drive gears 12 is horizontally slidably provided on the inner wall of the liquid collecting bottom shell 1.

[0047] The working principle of this device is as follows:

[0048] Liquid is injected into the storage cylinder 21 using the liquid filling cylinder 23. When it is necessary to test the permeability of the concrete block, the pressure cylinder 20 drives the storage cylinder 21 to move down. The telescopic rubber sleeve 25 is used to seal against the upper surface of the concrete block. Then the on / off valve 24 is opened, and the liquid flows through the storage cylinder 21 onto the concrete block to test the permeability of the concrete block.

[0049] The drive motor 5 drives the two clamping seats 4 to slide relative to each other, adjusts the distance between the two clamping seats 4, uses the bottom support plate 10 to support the concrete block, uses the buffer clamping plate 7 to clamp the end of the concrete block, and uses the elasticity of the tension spring 9 to clamp the concrete block. This can prevent the clamping seats 4 from rigidly contacting the concrete block in the traditional technology, prevent the concrete block from being broken or cracked, and ensure the accuracy of the concrete block permeability assessment.

[0050] Since the clamping seat 4 is slidably connected to the direction adjustment seat 3, the driving rack 13 is moved by the adjusting cylinder 16. The driving rack 13 uses the driving gear 12 to drive the direction adjustment seat 3 to swing, thereby realizing the reversal of the concrete block, eliminating the need to disassemble and fix the concrete block again, which is convenient and quick.
