Abstract
The invention relates to a pore forming method and a pore forming part of a special shape for connecting precast concrete units. During the manufacturing of the precast concrete units, connecting pores are required to be reserved, but most of the traditional reserved connecting pores are circular and have smooth inner pore surfaces, so that connection between precast concrete units connected by the reserved connecting pores is unreliable, the precast concrete units are easy to separate, and the service life of a building formed from the precast concrete units is influenced. The connecting pores are required to be reserved for the precast concrete units when the precast concrete units are manufactured, and embedded parts with specific pore pattern and specific inner pore surface shape are placed in the reserved connecting pores; then, the precast concrete units are cast; before concrete of the precast concrete units are finally set, the embedded parts are drawn out so that the reserved connecting pores form specific pore shape and specific concave and convex surface shape is formed in the pore. The reserved connecting pores of the precast concrete units are used for connecting and assembling the precast concrete units. The invention is used for lapping and connection of reinforced steel bars among the precast concrete units.

The described forming hole method that is used for the special shape of precast concrete connection, described specific pass built-in fitting cross section is profile circular arc or polygon or ellipse or broken line shape.
The described forming hole method that is used for the special shape of precast concrete connection, the given shape in the described preformed hole is that male and fomale(M﹠F) is ripple hole face or slit-like opening face or threaded hole face or point-like hole face.
A kind of pore-forming spare of the above-mentioned special shape that is used for precast concrete, described built-in fitting comprises the center drawer that is positioned at the built-in fitting center, described center drawer outer shroud winding component, described sub-assembly is one group.
The described pore-forming spare that is used for the special shape of precast concrete, described built-in fitting cross sectional shape are circular arc or polygon or ellipse or broken line shape.
The described pore-forming spare that is used for the special shape of precast concrete, described built-in fitting outer surface have ripple hole or slit-like opening or threaded hole or a point-like hole.
Utilization has the method that the precast concrete in special hole carries out construction: with precast concrete, be connected precast concrete and put, connecting reinforcement and embedded bar are placed, be inserted in reinforcement, sealing ring is put in bottom at above-mentioned preformed hole, in grout hole, pour into cement mortar, after cement mortar is filled, after static a period of time, when reaching construction requirement, the hardness of cement mortar finishes construction
Beneficial effect of the present invention:
1. ripple hole that pore-forming mode of the present invention forms or slit-like opening or threaded hole or point-like hole moral inner surface make the connection between member and the member more firm, tensile property is better, this product construction quality is easy to guarantee, the job site is to do operation substantially, all disadvantages of traditional reinforcing bar connected mode have fully been avoided, for assembling of precast concrete provides a new method.
2. the pore-forming mode that the present invention realized is simple to operate, and work progress does not need complicated mechanical equipment and facility, does not also need power consumption.The corrugated surface of reserving hole inwall or groove shape surface or helical surface or point-like surface can further strengthen the connection effect, so switching performance is more reliable, and characteristics are built in the construction that is suitable for the housing industrialization precast concrete again.
3. building course of the present invention is that environmental protection is energy-conservation again, production cost is low, without mechanized equipment, save and build economic expenditure, increase economic efficiency.
