Abstract
The invention discloses a template, in particular a ductile cast iron template which is cast from ductile cast iron QT500-7, and machined into a rectangular platform by utilizing a double housing planer, a miller and a grinder; the specifications of the rectangular correspond to those of a prefabricated plate; the internal design adopts a horizontal-vertical criss-cross multi-beam supporting structure; each criss-cross position adopts a circular structure; lifting circular holes are formed in a lateral surface of the ductile cast iron template; after manual polishing, the finish degrees of the upper surface, the bottom surface and each lateral surface of the ductile cast iron template are 3.2, 6.3 and 12.5 respectively; antirust paint is sprayed onto each non-working surface. The ductile cast iron template is high in precision, and the error can be smaller than 0.15 mm; the ductile cast iron template is high in strength, and can be repeatedly used for tens of thousands of times.
Description
Technical field
The present invention relates to building field, refer to the template for the production of precast slab especially.
Background technology
Intelligent assembly formula house, need to make a large amount of concrete abode house plates, traditional steel template, in use, intensity constantly weakens, can be out of shape when reaching surrender, in factorial praluction, use steel form not reach the indeformable requirement of production line Long-Time Service, therefore need a kind of precision higher, yield force is larger, not yielding, can at utmost nonexpondable template.
Summary of the invention
The invention provides that a kind of sound construction, yield force are high, resistance to compression damping, can be used for the template of the concrete abode house plate of production line balance.Described template for be cast by spheroidal graphite cast-iron QT500-7, through the rectangular platform that double housing planer, milling machine, grinding machine process.
The artificial polishing of described template upper surface reaches fineness 3.2, bottom surface fineness 6.3, side 12.5; Its precision is greatly improved, and control errors is in ± 0.15mm.
Described template indoor design is transverse and longitudinal and crossing number beam supporting construction, and infall is circular configuration, makes template face stress equalization, and holding capacity is large, not yielding firm and durable more, resistance to compression damping.
Described formwork sides is provided with lifting circular hole.
Described template inactive face rust prevention by applying liquid material paint, ensure the Long-Time Service not corrosion of template.
The spheroidal graphite cast-iron that yield force is higher is used to make template, and the supporting construction that reasonably design is inner, greatly improve the resistance to compression damping property of template, the process of plane, milling, mill multiple working procedure, more improves precision, ± 0.15mm is reduced to by the error ± 0.3mm of steel form, access times are also doubled to 10000 times by 5000 times, more meet the Production requirement of batch production, while each performance improves, price is but low than steel form, has saved cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of spheroidal graphite cast-iron template.
The schematic bottom view of Fig. 2 spheroidal graphite cast-iron template.
Fig. 3 is the A-A sectional view of Fig. 2.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described further:
As shown in Figure 1, described template is rectangle, forms through double housing planer, milling, mill, and upper surface 1 is level and smooth, after artificial aging process, fineness reaches 3.2, and side 2 fineness reaches 12.5, and is provided with lifting circular hole 3, except upper surface, all the other are non-working surface, the process of equal rust prevention by applying liquid material paint.
As shown in Figures 2 and 3, described template inside is provided with crossbeam 4, longeron 5, cross coupling 6, and crossover sites is circular 7 reinforcings.
Claims (5)
