Description

Technical Field

[0001] The utility model relates to a test fixture for splitting tensile strength of permeable bricks. Background Art

[0002] The splitting strength of a permeable brick refers to the resistance of the permeable brick to splitting under the action of a tensile force perpendicular to its surface direction. The splitting strength is an important mechanical property index of the permeable brick, which is used to evaluate its tensile capacity and the stability of the structure.

[0003] The splitting strength test is usually carried out by applying a force to the permeable brick to simulate the tensile stress situation that may be encountered in actual use. During the test, the permeable brick will split, and the maximum value of the applied tensile load is measured. This maximum load is the splitting strength of the permeable brick.

[0004] When the existing fixture applies a load to the permeable brick in the splitting tensile strength test of the permeable brick, the upper and lower pressure plates are prone to eccentricity, which in turn affects the accuracy of the test data of the splitting tensile strength of the permeable brick. Therefore, a test fixture for the splitting tensile strength of the permeable brick is proposed. Content of the Utility Model

[0013] Preferably, guiding wing plates for the linear movement of the upper pressing member are arranged on both sides of the upper pressing plate.

[0014] Preferably, guiding grooves for the linear movement of the upper pressing member are formed on both sides of the bearing plate, and the guiding grooves cooperate with the guiding wing plates.

[0015] Preferably, central scale lines for measuring the center line of the permeable brick are formed on both sides of the upper pressing plate and the lower pressing plate.

[0016] Preferably, grooves are formed on both sides of the bearing plate, and threaded grooves are formed at the grooves.

[0017] Preferably, the position adjusting assembly includes a push plate arranged at the groove, and the push plate is connected with a knob through a screw;

[0018] Wherein, the screw cooperates with the threaded groove.

[0019] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0020] By arranging the bearing plate, the upper pressing member and the lower pressing plate, the fixture can ensure that the permeable brick is uniformly extruded and loaded during the test through the combination of the bearing plate, the upper pressing member and the lower pressing plate, and reduce the influence of eccentric loading on the test result.

[0022] The upper pressing member includes an upper pressing plate, a pressure transmission column and a bearing plate. The pressure applied is transmitted to the upper pressing plate through the pressure transmission column, effectively distributing and uniformly loading the permeable brick, and improving the accuracy of the test.

[0023] The convex surfaces of the upper pressing plate and the lower pressing plate are arc-shaped and are placed opposite to each other to ensure uniform contact and pressure transmission during the loading process.

[0024] The guiding wing plates and guiding grooves in the fixture can realize the linear movement of the upper pressing member and ensure the stable movement of the upper pressing member, thereby improving the accuracy and reliability of the test.

Detailed Embodiment

[0032] In order to facilitate solving the problem that when the existing fixture applies a load to the permeable brick during the splitting tensile strength test of the permeable brick, the upper and lower pressing plates are prone to eccentricity, resulting in inaccurate data, the embodiment of the present invention provides a fixture for the splitting tensile strength test of the permeable brick. The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] Please refer to Figures 1-4 , the present invention provides a fixture for the splitting tensile strength test of the permeable brick, including a bearing plate 1 for loading the permeable brick, and grooves 102 are opened on both sides of the bearing plate 1, and thread grooves 103 are opened at the grooves 102.

[0034] Above the bearing plate 1, there is an upper pressing member 2 for extruding permeable bricks. Below the upper pressing member 2, the bearing plate 1 is provided with a lower pressing plate 3. The upper pressing member 2 includes an upper pressing plate 201, and the upper part of the upper pressing plate 201 is connected with a bearing plate 203 through a pressure transmission column 202. The cross-sectional shapes of the upper pressing plate 201 and the lower pressing plate 3 are both "convex", the convex surfaces of the upper pressing plate 201 and the lower pressing plate 3 are arc-shaped, and the convex surfaces of the upper pressing plate 201 and the lower pressing plate 3 are arranged opposite to each other. On both sides of the upper pressing plate 201, there are guiding wing plates 204 for the linear movement of the upper pressing member 2. On both sides of the bearing plate 1, there are guiding grooves 101 for the linear movement of the upper pressing member 2, and the guiding grooves 101 cooperate with the guiding wing plates 204.

[0035] Among them, the bearing plate 203 is used to transmit the bearing pressure to the upper pressing plate 201 through the pressure transmission column 202. On both sides of the upper pressing plate 201 and the lower pressing plate 3, there are center scale lines 5 for measuring the center line of the permeable brick.

[0036] The area between the upper pressing member 2 and the lower pressing plate 3 in the bearing plate 1 is the loading area of the permeable brick.

[0037] On both sides of the loading area, there is a position adjusting component 4. The position adjusting component 4 includes a push plate 401 arranged at the groove 102. The push plate 401 is connected with a knob 403 through a screw rod 402. Among them, the screw rod 402 cooperates with the thread groove 103.

[0038] Among them, the position adjusting component 4 is used to adjust the lateral position of the permeable brick.

[0039] The working principle of a splitting tensile strength test fixture for permeable bricks provided by the present utility model is as follows: Before clamping the permeable brick, first observe the surface of the permeable brick, find the center line of the permeable brick, and mark the marking points.

[0040] During use, place the permeable brick to be tested above the lower pressing plate 3 of the bearing plate 1, and then place the upper pressing member 2 above the permeable brick until the convex surface of the upper pressing plate 201 fits against the permeable brick.

[0041] The contact parts of the upper pressing plate 201 and the lower pressing plate 3 with the permeable brick are semi-cylinders. The upper pressing plate 201 can move up and down in the guiding grooves 101 through the guiding wing plates 204 on both sides.

[0042] By rotating the knobs 403 on both sides, the screw rod 402 is driven to rotate in the thread groove 103, controlling the position of the push plate 401, so that the push plate 401 pushes the permeable brick to a position where the center line of the permeable brick is aligned with the center scale lines 5 of the upper and lower pressing plates 3. When the center line of the permeable brick is aligned with the center scale lines 5 of the upper and lower pressing plates 3, the splitting tensile strength test of the permeable brick can be carried out.
