Description
Technical field
The present invention relates to building prefabricated components production technical field, more particularly to a kind of concrete prefabricated element and its shaping
Method.
Background technology
Concrete prefabricated element refers to the assembly concrete component for implementing to have completed before installing at the construction field (site), one
As common are precast concrete floor plate, bridge concrete box girder, industrial premises precast concrete roof truss beam, culvert frame
Structure, basement process precast concrete pile etc..
Traditional concrete prefabricated element is typically directly poured into a mould using mold cavity and formed, or in concrete prefabricated element
Internal reservation stiffener, and stiffener extends on the outside of component.The connecting end surface of both prefabricated components is typically more put down
It is sliding, undisguised material must be washed in advance before constructing at the scene.Also, easily collide and lack in lifting and transport process
Damage, the end face for being especially provided with connecting reinforcing bar is more fragile, in corner more cracky of the connection reinforcing bar by component when hitting.
The content of the invention
It is an object of the invention to provide a kind of concrete prefabricated element and its forming method, to solve to mix in the prior art
The smooth shortage anti-shear ability of end face, the poor cracky of end face strength, component entirety and site concrete that solidifying soil prefabricated components are present
The problem of connection is not enough consolidated.
To achieve these goals, the present invention uses following technical scheme：
A kind of concrete prefabricated element that the present invention is provided, including member bodies and connection end plate；On the connection end plate
Multiple through holes are set, and at least one end face of the member bodies is fixed in the connection end plate laminating.
Further, the connection end plate is in keyway is set in flat or the connection end plate, and the keyway is located at institute
State side of the connection end backboard from the member bodies.The technical scheme has technical effect that：When concrete prefabricated element is
During the component of house Beam groove locations etc, the connecting end surface of prefabricated components should typically set keyway.Therefore connection end backboard is from component
The side of body directly sets keyway, and required construction profile can be directly formed when pouring, and improves structure manufacture and engineering
Efficiency of construction.
Further, concrete prefabricated element also includes reinforcement；The reinforcement is located at the side of the connection end plate.Should
Technical scheme has technical effect that：Reinforcement can improve the mechanical strength of connection end plate.In addition, when reinforcement is arranged at company
When connecing the side of end plate laminating member bodies, reinforcement can be embedded in concrete, form connection end plate and member bodies are more firm
Connection.When reinforcement be arranged at connection end backboard from member bodies side when, it is possible to increase with the contact surface of cast-in-place part and
Anti-shear performance.Made it should be noted that connection end plate can select sheet metal, also there can be some strength using other
Nonmetallic materials make.
Further, the reinforcement includes multiple first reinforcements and multiple second reinforcements；Multiple described first strengthen
Muscle and multiple second reinforcement staggered arrangements；One institute is set between two adjacent first reinforcements of any row
State one first reinforcement of setting between the second reinforcement, two adjacent second reinforcements of either rank.The technology
Scheme has technical effect that：Large number of reinforcement staggered arrangement so that connection end plate and member bodies are after bonding
Shearing force is uniformly dispersed, and limits relative displacement between the two.Further, set between two adjacent the first reinforcements
One the first reinforcement is set between one the second reinforcement, two adjacent the second reinforcements, it is ensured that connection end plate is horizontal
With the rigidity of structure of longitudinal direction.
Further, concrete prefabricated element also includes structural framework and preformed hole；The preformed hole is arranged at the connection
On end plate, the structural framework is built in the member bodies and through the preformed hole.The technique effect of the technical scheme exists
In：Structural framework and concrete formed by integrally casting, greatly strengthen the structural strength of member bodies, and stretch out through preformed hole
Structural framework, the existing skeleton of structural framework and job site beneficial to prefabricated components realizes connection.
