The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.

According to the building test block manufacturing method, the slurry is poured into the test mold, and the test block is manufactured after maintenance is completed. As shown in fig. 1, the present application uses a bottomless mold 10 to make a test block, and closes the bottom end of the bottomless mold 10 with a film sheet 21 shown in fig. 2 before slurry is poured, so as to maintain moisture and make it easy to remove the test block after curing is completed. The example shown in fig. 1 is a conventional triple cast iron test block used to make a standard 70.7mm mortar test block. The three cavities of the bottomless test mold 10 are vertically communicated, so that water is easily lost from the bottom of the cavity after the mortar is poured. The film roll 20 shown in fig. 2 is formed by rolling a long polyethylene film, the polyethylene film is easily attached to the outer side surface of the bottomless test mold 10, and especially, when the outer side surface of the bottomless test mold 10 is wetted or treated by lubricating oil, the film sheet 21 can be attached to the bottom and the side surface of the bottomless test mold 10 to seal the opening of the bottom end, so that the water can be kept from being lost from below when mortar is poured into the mold cavity.

Of course, the bottomless mold 10 may be a single-unit bottomless mold or a multi-unit bottomless mold with other number of cavities, and all can be processed by using the film sheet 21 with a suitable size. The material of the bottomless test mold 10 can also be plastic or steel, or each part is made of cast iron, steel, plastic and other materials. The size of the die cavity can be other sizes, and the die cavity can be a combined trial die capable of adjusting the size of the die cavity.

Because the standard mortar test block is in a cube shape, the cross section of the triple bottomless test mold 10 is rectangular, the thin film sheet 21 is correspondingly rectangular, and the width and the length of the thin film sheet 21 are respectively greater than those of the cross section of the bottomless test mold 10, so that part of the thin film can be attached to the outer side surface of the bottomless test mold 10 after the thin film sheet 21 is attached to the bottom end of the bottomless test mold 10.

After the film sheet 21 is torn off, the films constituting the film roll 20 are still connected to each other, so that the film roll can be easily rolled. The tear structure 22 is a tear line formed by perforating with a laser drilling device in advance, so that the film sheet 21 can be easily torn off from the film roll 20 by hand or when the film sheet 21 is subjected to a vertical pushing force, and the remaining film can be kept together after the film sheet 21 is torn off, so that the film can be rolled up and kept clean in place.

In some embodiments, the tear structure 22 may also be a weakened structure formed by stamping, hot pressing, or the like, and the film roll 20 may also be made of a film made of polyvinyl chloride, polypropylene, polystyrene, or the like, and the thickness thereof may be flexibly set according to the requirement.

7. A building test block forming device is characterized in that,

comprises the test mold bottom sealing device, a machine frame, a test mold clamp, a stirring device, a first transmission device and a vibrating table of claim 5 or 6;

the die testing fixture is used for arranging the bottomless die testing fixture, the die testing fixture is connected to the rack, the die testing fixture can move along the rack and is used for transporting the bottomless die testing fixture to the working position of the die testing and bottom sealing device, and transporting the bottomless die testing fixture to the first conveying device after the bottom end of the bottomless die testing fixture is sealed by the thin film sheet;

the stirring device is arranged above the first conveying device and used for stirring and then filling slurry for manufacturing test blocks into a die cavity of the bottomless test die on the first conveying device, the first conveying device is used for conveying the bottomless test die to the vibrating table, and the vibrating table is used for compacting the slurry.

8. The building block molding apparatus of claim 7,

the frame is provided with a second driving device which is used for driving the die testing clamp to transport the bottomless die to the working position of the die testing and bottom sealing device, and transporting the bottomless die to the first conveying device after the bottom end of the bottomless die is sealed by the film sheet;

the building test block forming equipment further comprises a lubricating pool and a hanging rod, wherein a lubricant for helping the test block to be demoulded is arranged in the lubricating pool;

the hanger rod connects the test mold clamp to the second driving device, and the hanger rod is further used for extending the test mold clamp into the lubricating pool to lubricate the bottomless test mold.

9. The building block molding apparatus of claim 7,

the device comprises a first transmission device, a second transmission device and a floating device, wherein the first transmission device is arranged on the bottom of the mold, the floating device is arranged above the first transmission device and comprises a fixed seat and a scraper, the scraper is hinged to the fixed seat, and the width of the scraper is larger than that of the bottomless test mold;

the bottom of the fixed seat is higher than the top of the bottomless test mold on the first conveying device, and in a free state of the scraper, the bottom of the scraper is lower than the top of the bottomless test mold on the first conveying device;

when the bottomless test mold passes through the position below the floating device under the driving of the first conveying device, the scraper plate rotates under the pushing of the bottomless test mold, the bottom of the scraper plate slides over the top of the bottomless test mold, and slurry higher than the top of the bottomless test mold is scraped.

10. The building block molding apparatus of claim 8,

the die testing fixture comprises a rotating shaft and a chuck, the chuck is used for clamping the bottomless die testing, and the chuck is rotatably connected to the hanging rod through the rotating shaft;
