Description

Technical Field

[0001] This utility model relates to the field of grouting material performance testing technology, and in particular to a grouting material test block mold. Background Technology

[0002] The ambient temperature in northern my country is generally lower than in the south, especially in winter when temperatures can often drop below freezing. With the rapid development of green building materials, low-temperature construction is unavoidable. However, grouting materials designed for normal temperatures struggle to hydrate properly in low-temperature environments and are easily damaged by frost, resulting in slow strength development. Therefore, certain insulation measures, such as electrode heating or covering with additives, are generally required to meet technical requirements. This affects the construction process, increases costs, and, moreover, may lead to poor material performance and project quality due to insufficient protection. Research on the performance of grouting material test blocks is of great significance to the development of the construction economy.

[0003] The "Technical Specification for Application of Cement-Based Grouting Materials" (GB / T 50448—2015) stipulates that when the maximum aggregate particle size of cement-based grouting materials is no greater than 4.75mm, the standard specimen for compressive strength should be a prism with dimensions of 40mm×40mm×160mm. Currently, the commonly available 40mm×40mm×160mm triple molds are mainly divided into two types: a detachable iron mold and an integrated plastic mold. Both types of molds are difficult to demold at low temperatures. The iron mold is heavy and easily adheres to the grouting material at low temperatures. During demolding, it is usually necessary to knock the mold away from the specimen, causing fluctuations in the specimen strength. The plastic mold is usually demolded by air blowing, but the air blowing pressure can easily damage the specimen and affect its strength.

[0004] The problem that needs to be solved is how to provide a technical solution that produces good test block molding results and facilitates demolding. Summary of the Invention

[0005] The purpose of this invention is to address the problems existing in the prior art by providing a grouting material test block mold that has good molding effect, is easy to demold, and is convenient to operate.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a grouting material test block mold, including a base, the top surface of which is provided with an installation groove for setting the test mold, the test mold including a free mold cavity and a sliding mold cavity, the free mold cavity and the sliding mold cavity being arranged opposite to each other to form a test block cavity when joined, a partition plate being fitted inside the test mold, the width of the free mold cavity and the width of the sliding mold cavity being matched with the width of the installation groove, a plurality of sleeves being provided on the side of the sliding mold cavity, a crank handle and a plurality of driven wheels being rotatably provided on the front side of the base, the crank handle being connected to a driving wheel, the driving wheel being connected to the driven wheel through a transmission mechanism, a screw being provided on the driven wheel, the screw being screwed to the sleeve, and a movable limiting member being provided on the base for cooperating with the front side of the sliding mold cavity.

[0007] In the above scheme, an installation groove is opened on the top surface of the base to position the free mold cavity and the sliding mold cavity. The test mold has a snap-fit ​​partition to divide the test block cavity into multiple independent cavities, improving the production efficiency of test block casting. The width of the free mold cavity and the width of the sliding mold cavity are matched with the width of the installation groove, thereby limiting the sliding of the free mold cavity and the sliding mold cavity. A crank handle and a driven wheel are rotatably installed on the base. By turning the crank handle, the driving wheel is rotated, and the driven wheel and the screw are rotated through the transmission mechanism. A threaded hole is opened in the middle of the sleeve, and the screw is screwed to the sleeve on the sliding mold cavity, thereby driving the sliding mold cavity to move back and forth. When the rear side of the free mold cavity is in contact with the installation groove and the free mold cavity and the sliding mold cavity are connected, the front side of the sliding mold cavity is limited by the movable limiting component, thereby limiting the position of the free mold cavity and the sliding mold cavity, which facilitates the casting and molding of the grouting material test block and ensures the molding effect.

[0008] Furthermore, the movable limiting member includes a mounting block connected to the base, and a blocking block is rotatably provided on the mounting block.

[0009] The mounting block is connected and positioned to the base. Once the sliding mold cavity is in place, the front side of the sliding mold cavity is limited by rotating the blocking block to prevent loosening and ensure the molding effect of the concrete test block.

[0010] Furthermore, the blocking block is provided with an elastic element, and the elastic element is connected to a fitting element for cooperating with the sliding mold cavity.

[0011] The blocking block is connected to the elastic element, which in turn is connected to the bonding element, so that the bonding element can elastically limit the front side of the sliding mold cavity, resulting in a good limiting effect.

[0012] Furthermore, several partitions are arranged in parallel inside the mold, and connecting blocks are provided between the ends of the partitions. The bottom of the connecting blocks has a positioning groove for engaging with the edge of the free mold cavity.

[0013] Connecting blocks are used to connect several partitions, which facilitates the overall movement and installation of the partitions. The bottom of the connecting block is equipped with a positioning groove to cooperate with the edge of the free mold cavity, thereby positioning the free mold cavity, preventing the mold cavity from shifting back and forth, and facilitating operation.

[0014] Furthermore, grooves are provided on the inner sides of the free mold cavity and the sliding mold cavity, and the two ends of the partition plate are respectively engaged with the grooves.

[0015] The partition is positioned by engaging with the two ends of the partition through grooves.

[0016] Furthermore, the transmission mechanism includes a gear transmission component, a chain transmission component, or a belt transmission component.

[0017] Gear drives, chain drives, or belt drives have simple structures and good transmission performance.

[0018] Furthermore, a mounting part is provided on the front side of the base, and the crank handle is rotatably mounted on the mounting part.

[0019] The crank handle is limited to rotate via the mounting section.

[0020] Furthermore, the base has a fixing plate around its top perimeter for forming an installation groove, handles on both sides of the base, and an operating plate on the free mold cavity.

[0021] A mounting groove is formed by a fixing plate, and handles are provided on both sides of the base to facilitate the movement of the mold. The operating plate is used to facilitate the movement of the free mold cavity.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] 1. This utility model uses a movable limiting component to lock the connection between the free mold cavity and the sliding mold cavity, ensuring the stability of the mold structure and the good molding effect of the test block during the grouting and test block molding process;

[0024] 2. This utility model uses an installation groove on the base to slide and limit the free mold cavity and sliding mold cavity. It uses chain drive and the relative displacement of the sleeve and screw during rotation to control the disassembly and closure of the mold. This method makes demolding convenient and can minimize the disturbance of the grouting material test block to the greatest extent, ensuring the molding effect and ensuring the accuracy and authenticity of the strength data of the grouting material test block.

[0025] 3. The overall structure of the device is simple. Connecting blocks are set between the partitions to facilitate the installation and disassembly of the partitions. The mold is made of acrylic material, which is lighter than traditional molds and does not easily stick to the grouting material. It is easier to disassemble and clean in low-temperature environments, reducing manual working time and intensity. Attached Figure Description

[0033] like Figure 1-4As shown, a grouting material test block mold includes a base 1. The top surface of the base 1 has an installation groove 12 for setting the test mold. The test mold includes a free mold cavity 2 and a sliding mold cavity 4. The free mold cavity 2 and the sliding mold cavity 4 are arranged opposite each other to form a test block cavity 7 when they are joined. A partition 3 is fitted inside the test mold. The width of the free mold cavity 2 and the width of the sliding mold cavity 4 are matched with the width of the installation groove 12. Several sleeves 5 are provided on the side of the sliding mold cavity 4. A crank handle 8 and several driven wheels 10 are rotatably provided on the front side of the base 1. The crank handle 8 is connected to a driving wheel 9. The driving wheel 9 is connected to the driven wheel 10 through a transmission mechanism. A screw 6 is provided on the driven wheel 10. The screw 6 is screwed to the sleeve 5. A movable limiting member is provided on the base 1 for cooperating with the front side of the sliding mold cavity 4.

[0034] In the above scheme, the top surface of the base 1 has an installation groove 12 to position the free mold cavity 2 and the sliding mold cavity 4. The test mold has a partition plate 3 to divide the test block cavity 7 into multiple independent cavities, which improves the production efficiency of the test block casting. The width of the free mold cavity 2 and the width of the sliding mold cavity 4 are matched with the width of the installation groove 12, thereby limiting the sliding of the free mold cavity 2 and the sliding mold cavity 4. The base 1 is rotatably equipped with a crank handle 8 and a driven wheel 10. By turning the crank handle 8, the driving wheel 9 is driven to rotate, and the driven wheel 10 and the screw 6 are driven to rotate through the transmission mechanism. The sleeve 5 has a threaded hole in the middle, and the screw 6 is screwed to the sleeve 5 on the sliding mold cavity 4, thereby driving the sliding mold cavity 4 to move back and forth. When the rear side of the free mold cavity 2 is in contact with the installation groove 12 and the free mold cavity 2 and the sliding mold cavity 4 are connected, the front side of the sliding mold cavity 4 is limited by the movable limiting component, thereby limiting the position of the free mold cavity 2 and the sliding mold cavity 4, which facilitates the casting and molding of the grouting material test block and ensures the molding effect.

[0035] This utility model provides a grouting material test block mold, including a base 1. The base 1 is provided with a fixing plate around its perimeter. The fixing plate forms an installation groove 12 in the middle for placing the test mold. The width of the test mold is exactly matched with the fixing plate. The test mold includes two mold cavities and two partition plates 3. The free mold cavity 2 can be freely disassembled. Two sleeves 5 are provided on one side of the sliding mold cavity 4. The sleeves 5 are connected to the screws 6. The sleeves 5 and the screws 6 are connected by threads. The other side of the screws 6 is connected to a driven wheel 10. The driven wheel 10 is welded and fixed to the screws 6. The driven wheel 10 is connected to the driving wheel 9 through a transmission chain 11. The driven wheel 10 and the driving wheel 9 are completely identical in size and shape, and rotate in the same direction and angle as the driving wheel 9. The driving wheel 9 is connected to a crank handle 8 and is rotatably connected to the base 1.

[0036] The method of using this utility model is as follows: Before the test, apply a release agent to the inside of the test mold and around the partition plate 3. Place the free mold cavity 2 into the base 1 and fix the two partition plates 3 in the groove 19 inside the free mold cavity 2. Turn the crank handle 8 clockwise. The crank handle 8 drives the turntable and the driving wheel 9 to rotate clockwise. The driving wheel 9 drives the driven wheel 10 to rotate in the same direction and at the same angle. The driven wheel 10 drives the screw 6 to rotate clockwise. The screw 6 and the sleeve 5 are relatively displaced, forcing the sleeve 5 and the sliding mold cavity 4 to move towards the free mold cavity 2 until the sliding mold cavity 4 and the free mold cavity 2 are connected. The test mold is assembled. The sliding mold cavity 4 and the free mold cavity 2 are limited by the movable limiting member to maintain the connection state. The mold is then placed in a low-temperature environment for constant temperature. Pour the mixed low-temperature grout into the triple mold. After the grout has hardened, move the movable limiting piece to release the limit. Turn the crank handle 8 counterclockwise to rotate the turntable, driving wheel 9, driven wheel 10, and screw 6, forcing the screw 6 to move relative to the sleeve 5. The sliding mold cavity 4 and the free mold cavity 2 move away from each other, separating the grout sample from the mold cavity. Then remove the two partitions 3 from the middle of the sample to complete the demolding. If the grout sample is still connected to one of the mold cavities after the sliding mold cavity 4 and the free mold cavity 2 are separated, gently lift the operating plate 21 on the outside of the free mold cavity 2 to detach the free mold cavity 2 from the base 1, and move the grout sample from the mounting groove 12. Then continue the above steps to complete the demolding.
