Problems solved by technology

[0002] In the manufacture of precast concrete components, connection holes need to be reserved, but most of the reserved connection holes are circular, and the surface inside the hole is a smooth reserved connection hole. Due to the low friction, such reserved connection holes The connection between the connected precast concrete components is unreliable, and it is easy to cause separation between the precast concrete components, which affects the service life of the prefabricated concrete components assembled into the building

Embodiment 1

[0029] The method of forming holes with special shapes for the connection of precast concrete components. When making precast concrete components, precast concrete components need to reserve connection holes, and place embedded parts with specific hole types and specific shape surfaces in the reserved connection holes. Then pour the concrete components, before the concrete of the precast concrete components is finally set, the embedded parts are pulled out, so that the reserved connection holes have a specific hole type and a concave-convex surface of a specific shape in the holes, the reserved connection of the prefabricated concrete components Holes are used for connection and assembly between precast concrete components.

[0030] In the method for forming holes with special shapes for the connection of precast concrete components, the cross-sectional shape of the embedded part of the specific hole type is arc-shaped, polygonal, elliptical, or broken-line.

[0031] The surfa...

Embodiment 2

[0033] In the special-shaped hole-forming part for precast concrete components, the embedded part 1 includes a central drawing part 2 located in the center of the embedded part, and the central drawing part 2 surrounds the assembly 3, The described assembly is a set.

[0034] As for the special-shaped hole-forming part used for precast concrete components, the cross-sectional shape of the embedded part includes circular, square, elliptical, arc-shaped, polygonal or broken-line shapes.

[0035] The shape of the outer surface of the assembly is a corrugated surface or a grooved surface or a spiral surface or a dotted surface.

[0036] The method of using prefabricated concrete components with special holes for building construction, the prefabricated concrete components 4 and the connected prefabricated concrete components 5 are placed, the connecting steel bars 6 and pre-embedded steel bars 7 are placed, and the reinforcement bars 8 are inserted. Put the sealing ring 9 into th...

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.

Description

Technical field: [0001] The invention relates to a special-shaped hole-forming part and a hole-forming method, in particular to a special-shaped hole-forming method and a hole-forming part for the connection of prefabricated concrete components. Background technique: [0002] In the manufacture of precast concrete components, connection holes need to be reserved, but most of the reserved connection holes are circular, and the surface inside the hole is a smooth reserved connection hole. Due to the low friction, such reserved connection holes The connection between the connected prefabricated concrete components is unreliable, and it is easy to cause separation between the prefabricated concrete components, which affects the service life of the assembled prefabricated concrete components. Invention content: [0003] The purpose of the present invention is to provide a kind of application of the reserved holes in the prefabricated concrete components to connect the component...
