Description
Technical field
The present invention is technical field of civil engineering, and in particular to one kind construction refuse regenerated aggregate concrete is used as material
Reinforcement prefabricated regeneration concrete bean column node, it is adaptable in prefabricated concrete structure or half prefabricated half cast-in-place coagulation
In soil structure.
Background technology
Along with rapid economic development, China's appearance of city there occurs earth-shaking change, constantly expand in city space
While exhibition, the worry that building waste is brought also is continuously increased.But the discarded concrete in building waste can be made after crushing
It is regenerated aggregate manufacture building element, so as to solve the problems, such as that natural aggregate resource is nervous, while regeneration concrete water-retaining property, viscous
Poly- property superior performance.So this patent uses regenerated aggregate concrete as structure main material.
In recent years, China greatly develops elementary item construction, construction technology high speed development, assembled architecture and prefabricated components
It is employed extensively.It meets building industrialization and the requirement of green building.The pre- preparation, regeneration of reinforcement involved in the present invention is mixed
Solidifying soil bean column node combines conventional steel bar concrete technology maturation and the advantage both regeneration concrete, with low cost,
Construction is simple, and the duration is shorter, and many merits such as be conducive to preferably preserving the ecological environment.And in prefabricated construction central sill
With the anti-seismic performance and ultimate bearing capacity that the quality of post junction directly influences total.The prefabricated Recycled Concrete Beams
Column border node improves overall performance, stress performance and the workability of beam column, is suitable for different project situation demands.
The content of the invention
To provide, a kind of joint structure is simple, overall performance is good, difficulty that is producing and construct is low, environment-friendly economy is closed
The building structural element of reason, the invention discloses the prefabricated regeneration concrete bean column node and construction method of a kind of reinforcement.Using
Steel and regeneration concrete material are made, with construct convenient, function admirable, it is with low cost the characteristics of.
In order to realize above-mentioned requirements, the present invention takes following technical solution:A kind of pre- preparation, regeneration coagulation of reinforcement
Native bean column node, by precast concrete beam, precast concrete column component, vertical muscle, stirrup, angle steel and bolt connection piece group
Into.It is characterized in that:The prefabricated regeneration concrete bean column node strengthened is made up of four blocks of angle steel or two blocks of angle steel or two blocks of steel plates,
Simultaneously as the template for pouring prefabricated regeneration concrete bean column node, the spacing of two adjacent angle steels or steel plate subtracts both sides for deck-siding
Protective layer thickness, is bolted part connection;And laid along column length direction and beam length direction in adjacent angle steel institute clip space
Vertical muscle simultaneously uses stirrup colligation, extends certain length;Steel reinforcement cage is formed between the vertical muscle being arranged in a mutually vertical manner, as basic framework;
Pour into the prefabricated regeneration concrete bean column node that a kind of reinforcement is formed after regeneration concrete.
Node is controlled within 80cm along precast beam and prefabricated post direction extension according to practice of construction requirement.
Angle steel is welded by steel plate, is bolted part connection.Angle steel effectively improves phase instead of traditional handicraft
The obvious situation of stress concentration phenomenon at adjacent two limb knuckles, increases the shear resistance of beam.
Node end sets a square projection of 25cm high, precast concrete column component and precast concrete beam
Open the square groove of depth 30cm in end.The size of raised and groove determines by beam column actual size, raised size
The length of side is not less than 15cm, while the size length of side of groove cannot be greater than 30cm, has enough intensity to prevent junction.Prefabricated
The end reserved steel bar hole of beams of concrete component and precast concrete column component, as overhanging vertical muscle patchhole in node.And
In the side reserved steel bar grouting of precast concrete beam and precast concrete column component.Filled by pore pressure force of being in the milk during construction
Enter after strength cement-based grouting material tamps, stop grouting, rest 1-2 days.The setting of groove and projection and the side of preformed hole joint bar grouting
Method can make docking between beam column and node firm.
Using construction refuse regenerated aggregate concrete as primary building material, so as to reach environment-friendly, environmental protection
Purpose.
A kind of construction method of the prefabricated regeneration concrete bean column node of reinforcement, it is characterised in that:
(1)Vertical muscle, stirrup, the angle steel of appropriate length suitable dimension are selected, the pre- preparation, regeneration for completing to be arranged at reinforcement in factory is mixed
Vertical muscle, the arrangement along the vertically disposed vertical muscle in beam length direction and angle steel are set along column length direction in solidifying soil bean column node;Angle steel it
Between be bolted part connection, it is wrong to indulge muscle phase lap, uses stirrup colligation, forms steel reinforcement cage;
(2)Pour regenerated aggregate concrete and lifting crotch is installed, prefabricated regeneration concrete bean column node maintenance to be strengthened is hard
After change reaches design strength, and transport to job site;
(3)Prefabricated reinforced concrete column is installed on construction ground, first vertically-mounted, the prefabricated Recycled Concrete Beams that this kind is strengthened
Column border node is placed in cylinder top, and the groove that the raised and styletable for setting node is set is docked mutually;And by pre- preparation, regeneration coagulation
The reserved steel bar hole in vertical muscle insertion prefabricated post that native bean column node bottom is extended, cement-based grout is poured into by grout hole
Material is tamped;
(4)In the horizontal direction, precast beam is installed;Projection and beam that the prefabricated regeneration concrete bean column node that this kind is strengthened is set
The groove for setting is held to dock mutually, and on the vertical muscle insertion precast beam that prefabricated regeneration concrete bean column node bottom is extended
Reserved steel bar hole, pours into strength cement-based grouting material and tamps by grout hole;Maintenance hardening.
It is an advantage of the invention that:1. weaker, the poor seismic behavior of node is connected at usual precast concrete node,
The present invention use prefabricated concrete beam and column node so that structural integrity is preferable, rigidity is larger, anti-knock shock resistance performance compared with
It is good, reduce difficulty of construction and component cost.2. node skeleton is substituted with angle steel, improves the stress collection at adjacent two limbs knuckle
The middle obvious situation of phenomenon, is allowed to globality raising, and bearing capacity enhancing has more preferable shock resistance and shear behavior, facilitates and apply
Work.Template required for having saved precast concrete node, improves labour productive forces.3. in precast concrete beam column section
The junction setting groove of point and the method for raised preformed hole joint bar ensure bearing capacity, rigidity and the ductility of node and seam.4.
The present invention uses regenerated aggregate concrete, has green, energy-conservation, high-strength light and durability good compared to normal concrete, section
About cost the advantages of, realize recycling for building waste, saved the energy.5. construction technology of the present invention with pass
System technique is compared, and simplifies construction technology, reduces difficulty of construction, saves steel, and joint structure is relatively easy, conveniently applies
Work, while having preferable overall economic efficiency.
