Description

Technical Field

[0001] This utility model relates to the field of building material compressive strength technology, specifically a quick positioning fixture for a building material compressive strength test block. Background Technology

[0002] The ability of a material to resist damage under external force is called the strength of the material. When a material is subjected to external force, stress is generated inside it. As the external force increases, the stress increases accordingly until the bonding force between the particles inside the material is insufficient to resist the external force, at which point the material will fail. The limit value of stress reached when the material fails is called the ultimate strength of the material, usually represented by f. The unit of material strength is megapascal (MPa).

[0003] For example, patent document CN 208568462 U discloses a multifunctional fixture for testing the mechanical properties of concrete, belonging to the field of building materials and testing technology. The fixture includes an upper pressure plate, a lower pressure plate, an upper pad, and a lower pad; a cylinder I is provided on the upper pressure plate, and the upper pad is located between the cylinders I and can be fitted or separated from the cylinders I; the lower pressure plate is provided with positioning holes and a cylinder II, and a positioning rod is provided at the end of the cylinder II; one end of the lower pad is provided with a protruding nail positioning rod corresponding to the positioning hole of the lower pressure plate, so that the lower pad is fixed to the lower pressure plate by the protruding nail positioning rod. The multifunctional fixture for testing the mechanical properties of concrete disclosed in this utility model can quickly locate and accurately detect the compressive strength, flexural strength, splitting tensile strength, and axial compressive strength of concrete, improving the accuracy and efficiency of concrete mechanical property testing.

[0004] However, when this structure is used for actual compressive strength testing of building materials, due to its own structural limitations, the test blocks cannot be initially positioned and clamped. During subsequent pressure testing, instability under pressure is likely to occur, leading to inaccurate test results. At the same time, the equipment cannot perform more efficient continuous loading and unloading operations, which cannot meet the needs of daily use. Therefore, it is urgent to design a quick positioning fixture for building material compressive strength test blocks to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a quick positioning fixture for a building material compressive strength test block, in order to solve the problem mentioned in the background art that, due to the limitations of its own structure, the existing structure cannot perform the initial upper and lower positioning and clamping operation of the test block when conducting actual building material compressive strength testing. Subsequently, during the pressure test, it is easy to experience unstable pressure, resulting in inaccurate test results. At the same time, the equipment cannot perform more efficient continuous loading and unloading operations, and cannot meet the needs of daily use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick positioning fixture for a test block for compressive strength of building materials, comprising a testing frame, a conical top frame fixedly connected to the top of the testing frame, a conical bottom frame fixedly connected to the bottom of the testing frame, a first air pump provided at the bottom of the conical bottom frame, a positioning component provided at the center of the conical top frame and the conical bottom frame, and a material conveying component provided inside the testing frame;

[0007] The positioning component includes a storage ring cover, and the storage ring cover is disposed at the center of the conical top frame and the conical bottom frame. A hydraulic detection unit is disposed on the surface of the top storage ring cover.

[0008] The material feeding assembly includes a first drawer and a second drawer, and the first drawer and the second drawer are movably connected inside the detection frame.

[0009] Preferably, the first and second pull seats are fixedly connected to limit side plates at both ends, and a second air pump is provided at the center of the inner side plate.

[0010] Preferably, the inner walls of the first and second pull seats are provided with positioning side frames on all four sides, and a side top airbag is provided at the inner center of the positioning side frame.

[0011] Preferably, there is a positioning ring airbag between the upper and lower storage ring covers, and one end of the positioning ring airbag is fixedly connected to a positioning ring seat.

[0012] Preferably, the two sides of the testing frame are provided with sealing rings, and the inner wall of the testing frame is provided with a limiting inner liner.

[0013] Preferably, gas supply side pipes are provided at the center of both sides of the detection frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This rapid positioning fixture for building material compressive strength test blocks, through its testing frame, conical top frame, conical base frame, first-level air pump, storage ring cover, hydraulic testing unit, positioning ring airbag, positioning ring seat, and air supply side pipe, enables the equipment to quickly position and clamp the building material compressive strength test blocks inside the testing frame. In actual use, the operator first places the test block in the center position inside the testing frame. At this time, the first-level air pump at the bottom of the conical base frame can be activated, working in conjunction with the air supply side pipes on both sides of the testing frame to inflate the storage ring cover in the center of the conical top frame and conical base frame. This causes the positioning ring airbag between the upper and lower storage ring covers to extend and align towards the center. Through the positioning ring seat at one end of the positioning ring airbag, the test block located in the center of the testing frame is positioned and clamped. Simultaneously, the hydraulic testing unit at the top of the storage ring cover can be activated to apply stable and continuous pressure to the center of the test block, improving the final compressive strength test effect of the building material and demonstrating the practicality of the equipment design.

[0016] This rapid positioning fixture for building material compressive strength test blocks, through its testing frame, first and second pull-out seats, limiting side plates, second air pump, positioning side frame, side-top airbag, sealing ring, and limiting inner liner, further improves the overall usability of the equipment. During daily use, operators can slide the first and second pull-out seats back and forth within the testing frame via the limiting side plates at both ends. At this time, the first and second pull-out seats can be limited at the limiting inner liner on the inner wall of the testing frame, and the limiting side plates at both ends can also be limited and fitted at the sealing rings on both sides of the testing frame. Simultaneously, the second air pump inside the limiting side plate can be activated to inflate and deflate the four sides of the positioning side frame on the inner walls of the first and second pull-out seats, activating the internal side-top airbag for adaptation and expansion, achieving initial positioning and clamping of the test block, and more efficiently completing the compressive strength test operation, demonstrating the comprehensiveness of the equipment design.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 One embodiment provided by this utility model:

[0024] A quick positioning fixture for a building material compressive strength test block includes a testing frame 1. A conical top frame 2 is fixedly connected to the top of the testing frame 1, and a conical base frame 3 is fixedly connected to the bottom of the testing frame 1. A first air pump 4 is installed at the bottom of the conical base frame 3. A positioning component is installed at the center of the conical top frame 2 and the conical base frame 3. A material conveying component is installed inside the testing frame 1. Sealing rings 15 are installed on both sides of the testing frame 1. A limiting inner liner 16 is installed on the inner wall of the testing frame 1. Air supply side pipes 17 are installed at the center of both sides of the testing frame 1. When the first air pump 4 at the bottom of the conical base frame 3 is started, it works in conjunction with the air supply side pipes 17 at the center of both sides of the testing frame 1 to inflate the conical top frame 2 and the conical base frame 3 to the center of the internal storage ring cover 5, so that the positioning ring airbag 13 between the upper and lower storage ring covers 5 can extend and retract towards the center.

[0025] The positioning assembly includes a storage ring cover 5, a conical top frame 2, and a conical bottom frame 3. The storage ring cover 5 is located at the center of the interior. A hydraulic detection unit 6 is installed on the surface of the top storage ring cover 5. The material conveying assembly includes a first pull seat 7 and a second pull seat 8. The first pull seat 7 and the second pull seat 8 are movably connected inside the detection frame 1. Limiting side plates 9 are fixedly connected to both ends of the first pull seat 7 and the second pull seat 8. A second air pump 10 is located at the center of the interior of the limiting side plate 9. Positioning side frames are installed on all four sides of the inner walls of the first pull seat 7 and the second pull seat 8. 11. A side top airbag 12 is provided in the center of the internal part of the positioning side frame 11. A positioning ring airbag 13 is provided between the upper and lower storage ring covers 5. A positioning ring seat 14 is fixedly connected to one end of the positioning ring airbag 13. The first pull seat 7 and the second pull seat 8 are slid back and forth inside the testing frame 1 through the limiting side plates 9 at both ends. At this time, the first pull seat 7 and the second pull seat 8 can be limited with the limiting inner liner 16 on the inner wall of the testing frame 1, and the limiting side plates 9 at both ends can also be limited and fitted at the sealing rubber rings 15 on both sides of the testing frame 1.

[0026] Working Principle: During use, the user first places the test block into the center of the testing frame 1. Then, the first air pump 4 at the bottom of the conical base 3 is activated, working in conjunction with the air supply pipes 17 on both sides of the testing frame 1 to inflate the conical top frame 2 and the central receiving ring 5 inside the conical base 3. This causes the positioning ring airbag 13 between the upper and lower receiving rings 5 ​​to extend and retract towards the center. Through the positioning ring seat 14 at one end of the positioning ring airbag 13, the test block located at the center of the testing frame 1 is positioned and clamped. Simultaneously, the hydraulic testing unit 6 at the top of the receiving ring 5 is activated to apply stable and continuous pressure to the center of the test block, improving the final compressive strength testing effect of the building materials. During use, the operator can slide the first pull seat 7 and the second pull seat 8 back and forth inside the testing frame 1 through the limiting side plates 9 at both ends. At this time, the first pull seat 7 and the second pull seat 8 can be limited at the limiting inner liner 16 on the inner wall of the testing frame 1, and the limiting side plates 9 at both ends can also be limited and fitted at the sealing rubber rings 15 on both sides of the testing frame 1. At the same time, the second air pump 10 inside the limiting side plate 9 can be started to inflate and deflate the four-sided positioning side frame 11 on the inner wall of the first pull seat 7 and the second pull seat 8, which will activate the internal side top airbag 12 to adapt and extend, realizing the initial positioning and clamping of the test block, and completing the pressure resistance test operation more efficiently. The above is the entire working principle of this utility model.
