When using a mould device for improving the unloading rebound of the compression casting concrete, the method can be divided into the following five steps:
the first step is the preparation of the work,
the process needs to connect the pressure head structure formed by the pressure rod 23 and the pressure head structure 3 to the existing compression pouring equipment through the M12 internal threaded hole 22 at the top of the pressure rod 23 and the corresponding bolt.
The second step is the assembly process of the mould structure 1,
the process is sequentially carried out according to the up-down positions of the components,
firstly, the pressing bolt 13, the adjusting bolt 12, the pressing plate 11, the adjusting spring 24 and other components are assembled into the pressing plate structure 10, then the bottom plate structure 4 is placed on a flat ground, then the pressing plate structure 10 is connected to the bottom plate structure 4 through the adjusting bolt 12 structure formed by the adjusting bolt 12 and the adjusting spring 24, and the four pressing plate structures 10 are sequentially connected to the bottom plate structure 4.
Secondly, because the die structure 1 is composed of the first semicircular arc shaped steel sleeve 16 and the second semicircular arc shaped steel sleeve 17, and the die structure 1 and the bottom plate structure 4 are connected and fixed through three second fixing bolts 14 distributed at an included angle of 120 degrees, certain differences exist between the first semicircular arc shaped steel sleeve 16 and the second semicircular arc shaped steel sleeve 17, namely, two bolt holes are formed in the lower span 15 of the lower end of the first semicircular arc shaped steel sleeve 16, and only one bolt hole is formed in the lower span 15 of the lower end of the second semicircular arc shaped steel sleeve 17. Therefore, when the bottom plate structure 4 is connected with the first semicircular arc-shaped steel sleeve 16 and the second semicircular arc-shaped steel sleeve 17 of the die structure 1 through the second fixing bolts 14, the second semicircular arc-shaped steel sleeve 17 with two bolt holes on the lower span 15 needs to be connected and fixed first semicircular arc-shaped steel sleeve 16 is assembled through the centering buckle 25, so that the first semicircular arc-shaped steel sleeve 16 can be guaranteed to be connected and fixed on the bottom plate structure 4 quickly, and the assembly time is shortened.
Again, it is necessary to fix the first connection plate 18 of the first semicircular steel sleeve 16 and the second connection plate 19 of the second semicircular steel sleeve 17 with the third fixing bolt 20, and fix the mold removing bolt 21 in the corresponding fourth screw hole.
Finally, the four platens 11 are rotationally adjusted by adjusting the structure of the adjusting bolts 12 in the platen structure 10 to slightly press against the lower span 15 of the mold structure 1, and then the press bolts 13 apply pressure to the platens 11 so that they dead press the lower span 15 of the mold structure 1.
The third step is the pouring process:
the process is then carried out in a sequential order,
firstly, a layer of template oil needs to be brushed inside the die structure 1 assembled by the die structure 1 and the bottom plate structure 4, so that the concrete mixture is prevented from being adhered to the die structure 1, and the concrete test piece is prevented from being damaged during demolding.
Secondly, adding the freshly mixed concrete mixture into the die structure 1 assembled by the die structure 1 and the bottom plate structure 4 for three times, vibrating by using an inserted vibrating rod with the power of 3000 watts every time of pouring, continuously inserting and vibrating for 5-8 times (the vibrating times are related to the concrete mixing ratio, the shape of the die structure 1 and the like), and meeting the requirement that the quantity of the finally added concrete mixture just reaches the maximum capacity of the die structure 1.
Again, the anti-rebound platen structure 2 needs to be placed at the upper end of the die structure 1 assembled by the die structure 1 and the bottom plate structure 4, and the pressing raised head 6 of the anti-rebound platen structure 2 is guaranteed to be just inserted into the die structure 1, and then the die structure 1 is moved to align the pressing head structure 3 with the pressing groove 9 of the anti-rebound platen structure 2 (namely, the pressing head structure 3 can be vertically inserted into the pressing groove 9 of the anti-rebound platen structure 2).
Finally, the existing compression pouring equipment is started, the structure of the pressure head structure 3 is pressed into the compression groove 9 of the rebound prevention pressure disc structure 2, the pressing raised head 6 of the rebound prevention pressure disc structure 2 is used for compacting concrete in the die structure 1, after the compression pressure reaches the designed size, the compaction can be continuously carried out for a certain time (the time depends on the concrete material), the rebound prevention pressure disc structure 2 is completely fixed on the die structure 1 assembled by the die structure 1 structure and the bottom plate structure 4 through the first fixing bolt 5 on the premise of ensuring the unchanged compression pressure after compaction forming, then the compression pouring equipment is controlled to be unloaded, the whole die structure 1 is lifted from the compression pouring equipment after unloading, and the die is removed after 24 hours.
The fourth step is the process of removing the mould:
the process is also performed in a sequential order,
the first fixing bolt 5 and the third fixing bolt 20 need to be removed in sequence, and then the pressure applied by the second fixing bolt 14 and the releasing pressing plate structure 10 to the lower span 15 of the die structure 1 needs to be removed in sequence, wherein the releasing of the pressure applied by the pressing plate structure 10 to the lower span 15 of the die structure 1 is performed by releasing the pressure applied by the pressing bolt 13 to the pressing plate 11. Then, the demolding bolt 21 needs to be rotated to separate the first semicircular steel sleeve 16 and the second semicircular steel sleeve 17 of the mold structure 1, and finally, the rebound-preventing pressure plate structure 2 is taken away to take out a concrete test piece, and the concrete test piece is cured (for example, cured for 28 days under standard curing conditions) to obtain compression casting concrete without rebound.
And the fifth step is that the die structure 1 is cleaned and maintained:
the process only needs to clean the inner parts of the first semicircular arc-shaped steel sleeve 16 and the second semicircular arc-shaped steel sleeve 17 of the die structure 1 and the bottom plate structure 4, other steps are not needed, the pressing plate structure 10 is not needed to be detached, the pressing plate structure can be directly used in subsequent use, and the time for assembling the die structure 1 when the die structure 1 is repeatedly used in the subsequent process can be saved.
