Below with reference to Fig. 2 and Fig. 6, the method that adopts apparatus of the present invention 20 to make a product 50, for example precast slab is described.

Step 1: cleaning die

Be transported to behind the precalculated position on the guide rail 21 in each template 28, it has the face of side form member 31 members such as grade with cleanings such as brushes.Move them on one side singly, Yi Bian after cleaning, shift them onto assembling position again.Because the size of template 28 itself is very big, can clean with powered brush, to increase efficient.Because template 28, side form member 31, bed die member 32, Shang Jiao and following

corner member

33,34 etc. form whole mould 25, this whole mould is easy to clean under the state that is suspended on the guide rail 21, and not in prior art, need separately clean each member.

Step 2: spray releasing agent and assembly jig

After all the face of mould 25 cleans and finishes, releasing agent is sprayed onto on each face of template 28, then, each template 28 is moved on to the position of basic component 27, and template is in contact with one another with injector.Use bolt 44 (Fig. 5) to pass hole on the template 28 again, fix with nut 45.Like this, assembling die 26 is just assembled fixing.Because spray the assembling of releasing agent, mould and fixedly be under template 28 is suspended in state on the guide rail 21, to carry out, so can raise the efficiency.

Step 3: cast concrete slurry and swing die

In step 2, assembling die 26 is suspended on the guide rail 21 by suspension ring 28a, hook 29a, chain 29 and sliding part 22.When the 27 usefulness fork trucks of the basic component below being positioned at assembling die 26 promoted, assembling die 26 was being supported by basic component, chain 29 absent-mindedness.Then, if suspension ring 27c and fork truck that the hook 30a of steel wire rope 30 hooks on the basic component 27 descend, then assembling die 26 is only by chain 29 supportings.Therefore, assembling die 26 has sizable vibrational degrees of freedom.Starting is contained in the vibrator on assembling die 26 outer surfaces, vibrates this assembling die, and the top of concrete grout from assembling die poured into, and is filled in the mould 25 that forms between the template 28.Because assembling die 26 only is suspended in the air by four steel wire ropes 30, vibration is free, the good gong that is hanging with line that likes, and concrete grout can unhinderedly pour into and compacting.Vibration can adopt the vibratory equipment that is contained in place, a separation point position to carry out.Then, floating with trowel etc. the concrete surface in the assembling die.

According to this step, can pour into concrete grout in all moulds with single operation, therefore, pouring practice is quite simple.

Step 4: maintenance
