Description

Technical Field

[0001] The utility model belongs to the technical field of flow - state solidified soil, and particularly relates to a flow - state solidified soil test mold which is convenient for demolding. Background Technique

[0002] In the fields of civil engineering, geological research, building materials science, etc., the preparation and testing of flow - state solidified soil specimens are key links for evaluating the performance of new consolidation materials. At present, as a new building material, the preparation methods of flow - state solidified soil specimens mostly still follow the preparation methods of concrete specimens, and a small part uses geotechnical material test molds that are closer to the material properties of flow - state solidified soil. However, the above - mentioned test molds have the following deficiencies:

[0003] (1) The general method for demolding concrete specimens is to place the test mold on a plane and mainly use tools to strike the back or use an air pump or air gun to inject air into the test mold to achieve demolding. Since the strength of flow - state solidified soil is much lower than that of concrete, the above - mentioned methods are likely to damage the specimens.

[0004] (2) At present, geotechnical material test molds mainly use electric demolding devices for demolding. The operation of electric demolding devices is complicated and requires professional personnel to operate. Generally, only one test mold can be demolded at a time, and the efficiency is low. Content of the Utility Model

[0005] The purpose of the utility model is to provide a flow - state solidified soil test mold which is convenient for demolding, so as to solve the problems raised in the background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A flow - state solidified soil test mold which is convenient for demolding, including a bearing platform. Three rotating shafts are fixedly installed on the top surface of the bearing platform in a triangular distribution. A spring is sleeved on the periphery of each rotating shaft. A lower bearing plate is arranged above the bearing platform and between the three rotating shafts. Three solid cylinders are fixedly arranged on the top surface of the lower bearing plate in a triangular distribution. An active bearing platform is arranged above the three solid cylinders. Both the active bearing platform and the lower bearing plate are triangular structures. The active bearing platform is longitudinally inserted on the three rotating shafts. At the same time, the top end of each spring elastically abuts against the bottom surface of the corner of the active bearing platform, and the bottom end of the spring elastically abuts against the top surface of the bearing platform. A scraping plate is arranged at one corner of the top surface of the active bearing platform.

[0007] Preferably, sleeves are integrally connected to the three corners of the active bearing platform. The sleeves are longitudinally sleeved on the periphery of the adjacent rotating shafts. The top end of the spring elastically abuts against the bottom surface of the sleeve.

[0008] Preferably, three cylindrical cavities are arranged on the top surface of the active bearing platform in a triangular distribution. The three solid cylinders are longitudinally aligned with the three cylindrical cavities respectively.

[0009] Preferably, a connecting ring member is integrally connected to the tail end of the scraping plate, and the connecting ring member is rotatably connected to one of the rotating shafts.

[0010] Preferably, a convex block is integrally formed on the outer wall of one side of the lower bearing plate.

[0011] Preferably, a support column is fixedly connected to the middle position of the bottom surface of the lower bearing plate, and the bottom end of the support column is fixedly installed at the middle position of the top surface of the bearing platform.

[0012] Preferably, a plurality of fixing holes for connecting the bearing platform and other external fixing structures together by bolts are formed in the top surface of the bearing platform.

[0013] Compared with the prior art, the technical effects and advantages of the present utility model are as follows:

[0014] The flowable solidified soil test mold facilitating demolding,

[0015] (1) The operation is convenient. In the absence of an electric demolding device, rapid demolding can be achieved. Each time, a set of test pieces can be demolded, with high efficiency and less damage to the test pieces.

[0016] (2) A scraping device is provided at the top of the mold, avoiding the problem of uneven top ends of the test pieces that may be caused by manual scraping.

[0017] The design of the pre-tightening force of the spring ensures the pressure balance of the test pieces during the curing process, contributing to the uniformity of the internal structure of the material. At the same time, during demolding, the restoring force of the spring helps the movable bearing platform to smoothly separate from the test pieces, avoiding damage or deformation of the test pieces that may be caused by traditional demolding methods. The rotating design of the scraping plate simplifies the leveling process of the test piece surface, improves the surface quality of the test piece, and also reduces the operation difficulty and time cost. The limiting function of the convex block effectively prevents excessive operation during demolding, protects the test pieces from damage, and at the same time provides a better holding point for the operator, increasing the safety of the operation.

[0024] In the following description, a large number of specific details are given to provide a more thorough understanding of the present utility model. However, it is obvious to those skilled in the art that the present utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present utility model, some well-known technical features in the art are not described.

[0025] Unless otherwise defined, the up, down, left, right, front, back, inner and outer directions involved in this article are based on the up, down, left, right, front, back, inner and outer directions in the figure shown by the present utility model, and are hereby explained together.

[0026] This embodiment discloses a fluid-solidified soil test mold that is easy to demold as shown in Figures 1 to 3 the figure, which includes a bearing platform 12. Three rotating shafts 2 are fixedly installed on the top surface of the bearing platform 12 in a triangular distribution. A spring 7 is sleeved on the periphery of each rotating shaft 2. A lower bearing plate 9 is arranged between the three rotating shafts 2 and above the bearing platform 12. Three solid cylinders 6 are fixedly arranged on the top surface of the lower bearing plate 9 in a triangular distribution. An activity bearing platform 3 is arranged above the three solid cylinders 6. Both the activity bearing platform 3 and the lower bearing plate 9 are triangular structures. The activity bearing platform 3 is longitudinally inserted on the three rotating shafts 2. At the same time, the top end of each spring 7 elastically abuts against the bottom surface of the corner of the activity bearing platform 3, and the bottom end of the spring 7 elastically abuts against the top surface of the bearing platform 12. A scraping plate 1 is arranged at one corner of the top surface of the activity bearing platform 3.

[0027] Specifically, sleeves 5 are integrally connected to the three corners of the activity bearing platform 3. The sleeves 5 are longitudinally sleeved on the periphery of the adjacent rotating shafts 2. The top end of the spring 7 elastically abuts against the bottom surface of the sleeve 5. Three cylindrical cavities 4 are arranged on the top surface of the activity bearing platform 3 in a triangular distribution. The three solid cylinders 6 are longitudinally aligned with the three cylindrical cavities 4 respectively.

[0028] Specifically, a connecting ring member is integrally connected to the tail end of the scraping plate 1. The connecting ring member is rotatably connected to one of the rotating shafts 2. A raised block 8 is integrally formed on the outer wall of one side of the lower bearing plate 9. A support column 10 is fixedly connected to the middle position of the bottom surface of the lower bearing plate 9. The bottom end of the support column 10 is fixedly installed at the middle position of the top surface of the bearing platform 12. A plurality of fixing holes 11 are formed in the top surface of the bearing platform 12 for connecting the bearing platform 12 and other external fixing structures together by bolts.

[0029] Specifically, the scraping plate 1 rotates around the rotating shaft 2, and the leveling of the surface of the flowable solidified soil can be realized. The movable bearing platform 3 includes a cylindrical cavity 4. After the flowable solidified soil is prepared, it can be directly injected into the cylindrical cavity 4. The movable bearing platform 3 is connected to the sleeve 5. The sleeve 5 can slide up and down along the rotating shaft 2. The spring 7 can provide resistance for the sliding of the sleeve 5 to ensure that during the later demolding process, the movable bearing platform 3 slowly descends to ensure the demolding quality. The solid cylinder 6 is connected to the lower bearing plate 9. When the movable bearing platform 3 slides down, the solid cylinder 6 can eject the flowable solidified soil specimen. When the movable bearing platform 3 descends to a certain height, the raised block 8 can prevent the movable bearing platform 3 from continuing to slide down. The lower bearing plate 9, the support column 10 and the bearing platform 12 are connected. The bearing platform 12 is provided with fixing holes 11, and this test mold device can be fixed to other structures.

[0030] Working principle

[0031] For this flowable solidified soil test mold that is easy to demold, the movable bearing platform 3 is positioned above the lower bearing plate 9. At this time, the movable bearing platform 3 is stationary along the rotating shaft 2 through the sleeve 5, and a certain pre-tightening force is provided by the spring 7 to ensure a sealed space is formed between the movable bearing platform 3 and the lower bearing plate 9. The solid cylinder 6 is connected to the lower bearing plate 9 and together constitutes the bottom support structure of the flowable solidified soil specimen. The flowable solidified soil material is injected into the cavity formed by the cylindrical cavity 4 of the movable bearing platform 3 and the lower bearing plate 9. The scraping plate 1 rotates around the rotating shaft 2 to level the surface of the injected flowable solidified soil, ensuring that the surface of the specimen is flat and bubble-free, improving the quality and test accuracy of the specimen. During the curing process of the flowable solidified soil material, the movable bearing platform 3 remains stationary, and the pre-tightening force of the spring 7 helps to maintain the pressure balance of the specimen during the curing process and promotes the uniformity of the internal structure of the material. When the flowable solidified soil material is completely cured and reaches the required strength, an external force can be used to make the sleeve 5 slide upward along the rotating shaft 2, overcoming the resistance of the spring 7 and driving the movable bearing platform 3 to rise. During the rising process of the movable bearing platform 3, the solid cylinder 6 ejects the cured flowable solidified soil specimen from the lower bearing plate 9, realizing the preliminary separation of the specimen from the mold. When the movable bearing platform 3 rises to a certain height, the raised block 8 plays a limiting role to prevent damage to the specimen caused by over-lifting and ensure the smooth progress of the demolding process. The lower bearing plate 9 is connected to the bearing platform 12 through the support column 10, and the bearing platform 12 is provided with fixing holes 11, enabling the entire test mold device to be stably fixed on the experimental bench, facilitating the subsequent removal of the specimen and the reset operation of the test mold.
