Description

Technical Field

[0001] This application relates to the technical field of test molds, and particularly to a test mold for the anti-cracking performance of mortar. Background Art

[0002] Mortar is a bonding substance used for bricklaying in construction. It is synthesized by adding water to a certain proportion of sand and cementing materials (such as cement, lime paste, clay, etc.), also known as mortar. Commonly used mortars include cement mortar, mixed mortar (or cement-lime mortar), lime mortar, and clay mortar.

[0003] In the patent with the authorized publication number CN215574248U, a test mold for the anti-cracking performance of mortar, which relates to the technical field of mortar testing, includes at least two parallel side plates. The side plates are right-angled triangles, and one end of the short right-angled side of adjacent two side plates is connected by a baffle. The plane where the baffle is located is perpendicular to the plane where the side plates are located, and the baffle and adjacent two side plates enclose a containing cavity. The test mold for the anti-cracking performance of mortar provided by the present utility model can simultaneously test the anti-cracking performance of the same mortar with different thicknesses or different mortars with the same thickness, improving the test efficiency.

[0004] When the above device is implemented, it is impossible to detect the anti-cracking performance of mortar when it is at high temperature and wetted and soaked by rainwater, which will lead to insufficient accuracy in mortar testing and easy errors. Therefore, this application proposes a test mold for the anti-cracking performance of mortar to solve the above problems. Summary of the Utility Model

A heating pipe 15 is fixedly assembled on the bottom of the sealing cover 2.

[0030] Referring to Figure 2 , one end of the recovery pipe 4 far from the water storage tank 3 is communicated with the box body 1. A control valve is fixedly assembled on the outer edge of the recovery pipe 4, so that the water pump 5 can be driven to operate to pump the water in the inner cavity of the box body 1 to the inner cavity position of the water storage tank 3 through the recovery pipe 4 for storage, ensuring that the water source can be reused and the loss can be reduced. And through the control valve, it can be ensured that the water in the inner cavity of the box body 1 will not be discharged to the outside through the recovery pipe 4 randomly during the mortar test.

[0031] Referring to Figure 2 and Figure 4 , a submersible pump is provided in the inner cavity of the water storage tank 3, and the output end of the submersible pump is fixedly connected to one end of the connecting pipe 6 close to the water storage tank 3. By driving the submersible pump to operate, the water in the inner cavity of the water storage tank 3 can be discharged to the inner cavity position of the shunt pipe 7 through the connecting pipe 6, and then the two nozzles 8 can be used to spray water on the outside to wet the mortar.

[0032] Referring to Figure 4 and Figure 5 , the heating pipe 15 is arranged directly above the mold plate 13, and the two nozzles 8 are symmetrically arranged on both sides of the mold plate 13 in an inclined state. The shunt pipe 7 is a flexible rubber hose, so that the heating pipe 15 can be used to bake the mortar in the inner cavity of the mold plate 13, so as to observe the state of the mortar when it is baked at high temperature, and the state of the mortar after the dry mortar is sprayed with water by the nozzles 8, and observe whether it cracks to inspect the quality of the mortar.

[0033] Referring to Figure 4, there are two motors 9, lead screws 10 and sliders 11 each, and the two motors 9, lead screws 10 and sliders 11 are symmetrically arranged at the inner wall position of the box body 1. Both sides of the connecting plate 12 are fixedly connected to the two sliders 11 respectively, so that the two motors 9 drive the two lead screws 10 to rotate, thereby driving the two sliders 11 to move up and down synchronously. Furthermore, the connecting plate 12 and the mold plate 13 can be driven by the two sliders 11 to move up and down, and then the distance between the mold plate 13 and the heating tube 15 can be quickly adjusted, and it is convenient to move the mold plate 13 to the bottom position of the inner cavity of the box body 1 to ensure that it is fully soaked in water.

[0034] Refer to Figure 3 and Figure 4 , two square grooves 14 are symmetrically opened on the inner side of the box body 1.

A bearing is fixedly assembled at the bottom of the square groove 14, and the bottom end of the lead screw 10 is fixedly connected to the inner ring of the bearing, so that the two rotating lead screws 10 can be positioned, and further ensure the stability of the lead screw 10 during rotation, and ensure that it will not randomly shift and shake in position.

[0035] Refer to Figure 1 , support legs 16 are symmetrically and fixedly assembled at the bottoms of the box body 1 and the water storage tank 3. An inlet is fixedly installed at the top of the water storage tank 3, and a handle is fixedly assembled at the top of the sealing cover 2, so that the box body 1 and the water storage tank 3 can be stably placed to ensure their stability, and water can be discharged into the inner cavity of the water storage tank 3 through the water inlet for storage. At the same time, the convenience of the user to open the sealing cover 2 is increased by using the set handle.

[0036] Working principle: When using this device, first pour the mortar onto the inner wall of the mold plate 13, and then wait for it to cool and solidify. At the same time, the handle can be pulled to close the sealing cover 2 to the top position of the box body 1, and then the heating tube 15 can be driven to heat and bake the mortar in the inner cavity of the mold plate 13, so as to observe the state of the mortar when it is baked at high temperature. By driving the submersible pump to operate, the water in the inner cavity of the water storage tank 3 can be discharged through the connecting pipe 6 into the inner cavity of the shunt pipe 7, and then sprayed to the outside through the two nozzles 8 for wetting the mortar to observe whether it cracks, and the quality of the mortar can be inspected. The sprayed water will accumulate at the inner bottom position of the box body 1, and then the two motors 9 can be driven to drive the two lead screws 10 to rotate, thereby driving the two sliders 11 to move up and down synchronously. Furthermore, the connecting plate 12 and the mold plate 13 can be driven by the two sliders 11 to move downward, so that the mold plate 13 can be moved to the bottom position of the inner cavity of the box body 1 to ensure that it is fully soaked in water, and observe the state of the mortar after being soaked in water. After soaking, the water in the inner cavity of the box body 1 can be pumped into the inner cavity of the water storage tank 3 through the recovery pipe 4 by driving the water pump 5 for storage and recycling, ensuring that the water source can be reused and reducing losses.
