Description

A kind of prefabricated regeneration concrete bean column node of reinforcement
Technical field
The utility model is technical field of civil engineering, and in particular to it is a kind of by the use of construction refuse regenerated aggregate concrete as The prefabricated regeneration concrete bean column node of the reinforcement of material, suitable for prefabricated concrete structure or half prefabricated half is cast-in-place In concrete structure.
Background technology
Along with rapid economic development, China's appearance of city constantly expands there occurs earth-shaking change in city space It is worried caused by building waste to be also continuously increased while exhibition.But the discarded concrete in building waste can be made after crushing Building element is manufactured for regenerated aggregate, so as to solve the problems, such as natural aggregate resource anxiety, and meanwhile it is 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.Reinforcement involved by the utility model it is prefabricated again Growing concrete bean column node combines conventional steel bar concrete technology maturation and the advantage both regeneration concrete, has cost Low, construction is simple, the duration is shorter, and many merits such as be advantageous to preferably to preserve the ecological environment.And in prefabricated construction The quality of central sill and post junction directly influences the anti-seismic performance and ultimate bearing capacity of total.The prefabricated regeneration coagulation Native bean column node improves the overall performance, stress performance and workability of beam column, is suitable for different project situation demands.
Utility model content
To provide, a kind of joint structure is simple, overall performance is good, production is low with the difficulty of construction, environment-friendly economy is closed The building structural element of reason, the utility model discloses the prefabricated regeneration concrete bean column node and construction method of a kind of reinforcement. It is made of steel and regeneration concrete material, there is the characteristics of constructing convenient, function admirable, cheap cost.
In order to realize above-mentioned requirements, the utility model takes following technical solution:A kind of pre- preparation, regeneration of reinforcement Concrete beam and column node, by precast concrete beam, precast concrete column component, vertical muscle, stirrup, angle steel and bolt connection piece Composition.It is characterized in that:The prefabricated regeneration concrete bean column node strengthened is by four blocks of angle steel or two blocks of angle steel or two pieces of steel plate structures Into, while as the template for pouring prefabricated regeneration concrete bean column node, the spacing of two adjacent angle steels or steel plate subtracts for deck-siding Both sides protective layer thickness, it is bolted part connection;And along column length direction and beam length direction in adjacent angle steel institute clip space The vertical muscle of laying simultaneously uses stirrup colligation, extension certain length;Steel reinforcement cage is formed between the vertical muscle being arranged in a mutually vertical manner, as basic bone Frame;Pour into after regeneration concrete and form a kind of prefabricated regeneration concrete bean column node of reinforcement.
Node requires control within 80cm along precast beam and prefabricated post direction extension according to practice of construction.
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, increase the shear resistance of beam.
One high 25cm of node end set square is raised, precast concrete column component and precast concrete beam Open the square groove of deep 30cm in one in end.Raised and groove size 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, to prevent junction from having enough intensity.Prefabricated The end reserved steel bar hole of concrete beam components 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 during construction by pore pressure force of being in the milk Enter after strength cement-based grouting material tamps, stop grouting, rest 1-2 days.Groove and raised setting and the side of preformed hole joint bar grouting Method, which can make to dock between beam column and node, to be consolidated.
It is environment-friendly, green so as to reach using construction refuse regenerated aggregate concrete as primary building material Purpose.
A kind of construction method of the prefabricated regeneration concrete bean column node of reinforcement, it is characterised in that:
(1)Select appropriate length suitable dimension vertical muscle, stirrup, angle steel, factory complete be arranged at reinforcement it is prefabricated again Vertical muscle, the arrangement along the vertically disposed vertical muscle in beam length direction and angle steel are set along column length direction in growing concrete bean column node;Angle Part connection is bolted between steel, indulges muscle phase lap mistake, with stirrup colligation, forms steel reinforcement cage;
(2)Pour regenerated aggregate concrete and lifting crotch is installed, prefabricated regeneration concrete bean column node to be strengthened is supported After shield hardening reaches design strength, and transport to job site;
(3)Prefabricated reinforced concrete column is installed on construction ground, first vertically-mounted, the pre- preparation, regeneration coagulation that this kind is strengthened Native bean column node is placed in above cylinder, the projection that node is set and the groove that styletable is set is docked mutually;And by pre- preparation, regeneration The reserved steel bar hole in vertical muscle insertion prefabricated post that concrete beam and column node bottom is extended, cement base is poured into by grout hole Grouting material tamps;
(4)In the horizontal direction, precast beam is installed;The projection that the prefabricated regeneration concrete bean column node that this kind is strengthened is set The groove set with beam-ends docks mutually, and the vertical muscle that prefabricated regeneration concrete bean column node bottom is extended inserts precast beam On reserved steel bar hole, strength cement-based grouting material is poured into by grout hole and tamped;Maintenance hardening.
The utility model has the advantages that:1. weaker, the anti-seismic performance of node is connected at usual precast concrete node Difference, the utility model use prefabricated concrete beam and column node so that structural integrity is preferable, rigidity is larger, anti-knock shock resistance Better performances, reduce difficulty of construction and component cost.2. node skeleton is substituted with angle steel, improve at adjacent two limbs knuckle The obvious situation of stress concentration phenomenon, globality raising is allowed to, bearing capacity enhancing, has more preferable shock resistance and shear behavior, side Construction.The template required for precast concrete node has been saved, has improved labour productive forces.3. in precast concrete The junction of bean column node sets the method for groove and raised preformed hole joint bar to ensure the bearing capacity of node and seam, rigidity and prolong Property.4. the utility model uses regenerated aggregate concrete, there is green, energy-conservation, high-strength light and durable compared to normal concrete Property is good, it is cost-effective the advantages that, realize recycling for building waste, saved the energy.5. it the utility model is related to Construction technology simplifies construction technology compared with traditional handicraft, reduces difficulty of construction, saves steel, and joint structure is relative Simply, convenient construction, while there is preferable overall economic efficiency.
