Description

Technical Field

[0001] This utility model relates to the field of engineering quality testing technology, specifically a permeameter for engineering quality testing. Background Technology

[0002] Building quality inspection is an important task to ensure the safety of completed, under-construction, and planned building projects. It involves testing the foundation, building materials, construction techniques, and building structure throughout the entire construction process. Cement is the most commonly used building material. As an important gelling material, cement is not only used for bonding rigid materials but also for sealing. Therefore, the waterproof performance of cement used for sealing is particularly important. Testing the waterproof performance of cement usually requires using a permeameter to measure the cement after it has solidified.

[0003] The existing cement concrete permeameter uses a test mold that is bolted to the instrument body. Before testing, the test mold needs to be disassembled and removed to measure its upper and lower diameters. After testing, the test mold also needs to be disassembled to remove the cement sample. During disassembly and installation, a wrench is needed to remove the bolts from the test mold, and a wrench is also needed to tighten the bolts during installation. This makes the disassembly and installation of the test mold quite troublesome and reduces the efficiency of testing.

[0004] Chinese patent disclosure for a penetrant tester for building engineering quality testing (authorization announcement number CN217981176U) describes a technology that adds a retaining edge to the base of the mold body. Two sets of retaining blocks are symmetrically connected to the side of the retaining edge, dividing the mold body into a cylindrical body and a connecting platform. A movable groove is formed on the lower surface of the connecting platform, with two sets of retaining slots and two sets of locking slots symmetrically formed at the bottom of the movable groove. The retaining slots are through-slot structures, and the locking slots are blind slot structures. The positions of the two sets of retaining slots and the two sets of locking slots are perpendicular to each other. The two sets of retaining blocks on the retaining edge enter the movable groove through the retaining slots. After rotating 90°, the retaining blocks enter the locking slots, realizing the mold... The fixed connection between the base and the main body of the test mold does not require additional tools, and disassembly and installation are relatively convenient. This effectively solves the problem that the test mold installed on the existing cement concrete permeameter is fixed to the main body of the instrument with bolts. Before testing, the test mold needs to be disassembled and removed to measure the upper and lower diameters of the test mold. After testing, the test mold also needs to be disassembled to remove the cement sample. During the disassembly and installation of the test mold, a wrench is needed to remove the bolts on the test mold, and during installation, a wrench is also needed to tighten the bolts. This makes the disassembly and installation of the test mold relatively troublesome and reduces the efficiency of testing.

[0005] However, it has certain drawbacks: although it replaces the traditional bolt fixing method, multiple test molds still need to be disassembled and assembled one by one, and it is impossible to achieve simultaneous disassembly and assembly of multiple test molds. Utility Model Content

[0006] The purpose of this invention is to provide a permeameter for engineering quality testing, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A permeameter for engineering quality testing includes a permeameter body, the upper surface of which has a plurality of water holes from front to back, and a mold base is fixedly connected to the upper surface of the permeameter body outside the water holes, and a test mold is placed on top of the mold base.

[0009] The upper surface of the permeameter body is provided with a positioning mechanism on the right side of multiple mold bases. The positioning mechanism includes multiple positioning rings arranged from front to back. A first support rod is fixed between each two adjacent positioning rings. A second support rod is fixed to the right side surface of the middle positioning ring. The positioning mechanism also includes an adjustment mechanism that drives the positioning rings to rise and fall.

[0010] As a further embodiment of this utility model: the adjustment mechanism includes a C-shaped plate, a rack is slidably connected to the inner left side surface of the C-shaped plate, a support block is fixedly connected to the lower end of the rack, a motor is fixedly connected to the front surface of the C-shaped plate, and a gear is fixedly connected to the output end of the motor.

[0011] As a further improvement of this utility model, a sealing ring is embedded and fixed on the upper surface of the mold base.

[0012] As a further embodiment of this invention: the number of positioning rings is equal to the number of test molds, and the inner diameter of the positioning rings is equal to the outer diameter of the test molds, with the positioning rings directly opposite the test molds.

[0013] As a further embodiment of this utility model: the right end of the second support rod is fixed to the left side surface of the C-shaped plate, the support block is fixed to the upper surface of the permeameter body, and the gear is meshed with the rack.

[0014] As a further improvement of this utility model, the sealing ring is a component made of an elastic material.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This utility model features a positioning mechanism. The motor in the positioning mechanism drives the gear to rotate, causing the C-shaped plate to move the positioning ring up and down. When the positioning bolt descends to the lowest point, it is fitted onto the outside of the test mold and presses the test mold onto the mold base. This achieves synchronous fixing of multiple test molds, eliminating the need to fix them one by one, and greatly improving the ease of assembly and disassembly of the test molds.

[0022] Please see Figures 1-4 In this embodiment of the present invention, a permeameter for testing engineering quality includes a permeameter body 1. The upper surface of the permeameter body 1 is provided with a plurality of water holes 2 from front to back, and a mold base 3 is fixedly connected to the upper surface of the permeameter body 1 outside the water holes 2. A test mold 4 is placed on top of the mold base 3.

[0023] The upper surface of the permeameter body 1 is provided with a positioning mechanism 5 on the right side of multiple mold bases 3. The positioning mechanism 5 includes multiple positioning rings 6 arranged from front to back. The number of positioning rings 6 is equal to the number of test molds 4, and the inner diameter of the positioning rings 6 is equal to the outer diameter of the test molds 4. The positioning rings 6 are directly opposite the test molds 4. A first support rod 7 is fixed between two adjacent positioning rings 6. A second support rod 8 is fixed to the right side surface of the middle positioning ring 6. The positioning mechanism 5 also includes an adjustment mechanism 9 that drives the positioning rings 6 to rise and fall. The adjustment mechanism 9 includes a C-shaped plate 10. The right end of the second support rod 8 is fixed to the left side surface of the C-shaped plate 10. A rack 11 is slidably connected to the inner left side surface of the C-shaped plate 10. A support block 12 is fixed to the lower end of the rack 11. The support block 12 is fixed to the upper surface of the permeameter body 1. A motor 13 is fixed to the front surface of the C-shaped plate 10. A gear 14 is fixed to the output end of the motor 13. The gear 14 is meshed with the rack 11.

[0024] Water hole 2 is connected to the water supply equipment, and the water supply equipment discharges water through water hole 2 for seepage detection;

[0025] After the concrete test blocks were made, they were pressed into test mold 4;

[0026] The trial mold 4 consists of a mold body and a flange fixed to the lower end of the mold body. The inner diameter of the positioning ring 6 is equal to the outer diameter of the mold body.

[0027] Motor 13 is equipped with a brake, meaning that the motor shaft cannot rotate after power is cut off;

[0028] When gear 14 rotates clockwise, C-shaped plate 10 will descend; when gear 14 rotates counterclockwise, C-shaped plate 10 will rise.

[0029] When the positioning ring 6 descends to its lowest point, it can be placed over the outside of the test mold 4 and press the test mold 4 onto the mold base 3, thereby achieving synchronous fixation of multiple test molds 4.
