Description
Technical field
The invention belongs to technical field of buildings, more particularly to a kind of reinforced assembled beam-column connecting node.
Background technique
China from five sixties of 20th century begin one's study assembly concrete build design and construction technology, form one
Serial assembly concrete building system, more typical building system have assembled single storey industry workshop building system, assembly
Formula multistory frame building system, assembled large panel building system etc..The application built to assembly concrete the 1980s
Reach the period of full bloom, many places in the whole nation all form the integrated assembly concrete industry of design, production and construction and installation
Change architectural mode assembly concrete building and two kinds of most important building bodies are become using the masonry building of prefabricated hollow floor
System, application popularization rate is up to 70% or more.To mid-term the 1990s, assembly concrete building is gradually by complete cast-in-place coagulation
Native building system replaces, at present except assembled single storey industry workshop building system is using in addition to wide.Other are prefabricated assembled to build
The engineer application of building body system is few.The globality of precast construction antidetonation and the specialized research of management in design and operation are inadequate, cause
Its Technical Economy is poor.It is the basic reason for causing precast construction to stagnate for a long time.
Wherein greatest problem be related to connecting node connection it is unstable, the problem of being not connected firmly, develop a kind of assembly
The connection of formula reinforcement type node solves the problems, such as us mainly at this stage.
Summary of the invention
In order to solve above-mentioned technical problem, the present invention provides a kind of reinforced assembled beam-column connecting node, main
It will be in order to develop a kind of good integrity, simple structure, easy to connect, safe and reliable assembled beam-column connecting node, Neng Gouyou
The solution constructional difficulties of effect, installation is complicated, construction is cumbersome, long construction period, is not connected firmly, the problems such as stability is not high.
The technical solution adopted by the invention is as follows:
Overhanging master in a kind of reinforced assembled beam-column connecting node, including prefabricated post, precast beam, L-type reinforcement by connection steel plate, column
Reserve that cage bar holes, reserved square type groove, L-type groove, main reinforcement connection hole, square type connection rib, coupling beam screw thread are short on beam in muscle, column
The high-strength node dowel of muscle；The prefabricated post, precast beam are whole steel and concrete structure；The prefabricated post is all disposed with pre- up and down
Square type groove is stayed, sectional dimension is the sectional dimension of half of prefabricated beam end, is disposed with four columns inside the prefabricated post
Interior overhanging main reinforcement, the length of overhanging main reinforcement is identical as the length of prefabricated post in the column, and overhanging main reinforcement is in prefabricated post in column
Side is overhanging, and prefabricated post arranged beneath, which has, reserves cage bar holes in column, overhanging main reinforcement in the column on the upside of prefabricated post for accepting lower section,
And it is disposed with main reinforcement connection hole in the downside circumferential surface of prefabricated post, shape is rectangle, will be upper in main reinforcement connection hole
Under prefabricated post column in overhanging main reinforcement welded, upper and lower prefabricated post is connected as entirety to reach；
The precast beam both ends are disposed with square type on beam and connect rib, and one end is arranged in top, and the other end is arranged in lower section, makes phase
Square type connection rib can agree with corresponding arrangement on beam on two adjacent precast beams, in order to which the head and the tail between precast beam sequentially connect
It connects, and center is disposed with spiral hole on square type connection rib on beam, after being docked between adjacent precast beam, square type on beam
The spiral hole arranged on connection rib can correspond to, and be attached adjacent precast beam using the short muscle of coupling beam screw thread；It is described
Prefabricated post on four columns in be arranged symmetrically four L-type grooves on the outside of overhanging main reinforcement, the L-type groove size caters to L
Type reinforcement by connection steel plate, prefabricated beam connecting node are overlapped on the reserved square type groove of prefabricated post, four L-type reinforcement by connection steel
Plate is arranged in L-type groove, and the longer edge of a wing of L-type reinforcement by connection steel plate is arranged in precast beam connection direction, parallel with precast beam,
And two reinforced holes symmetrical above and below are disposed on the longer edge of a wing, and be disposed on prefabricated post, precast beam and L-type reinforcement by connection steel
The corresponding reinforced hole of plate, after arranging L-type reinforcement by connection steel plate, prefabricated post, precast beam, on L-type reinforcement by connection steel plate
Reinforced hole can correspond to, and prefabricated post, precast beam, L-type reinforcement by connection steel plate are linked as entirety using high-strength node dowel.
Further, square type connection rib width is identical with precast beam on the beam, is highly the half of precast beam.
Further, main reinforcement connection hole surface is levelling using concrete mortar.
Further, beam column reinforces L-type corner steel plate and is arranged in bean column node surrounding, and length is of same size with precast beam,
Both wings edge is overlapped on prefabricated post, on precast beam respectively, and the prefabricated post, precast beam and beam column are reinforced on the steel plate of L-type corner all
Symmetrical two prepared screw-bolt holes are disposed with, are fixed using high-strength bolt；Beam column reinforcing L-type corner steel plate makes integrally steady at node
It is qualitative to further enhance, relative displacement is prevented, shear resistance is improved.
Further, in the downside of prefabricated post, main ribs connect hole and L-type groove in not the same side, and main reinforcement connects
The horizontal position at hole is connect on L-type groove top.
Further, overhanging main reinforcement is arranged in the protrusion of reserved square type groove two sides in four columns.
Beneficial effects of the present invention:
The advantages of the present invention are the L-type steel plates added inside column itself while connecting two columns up and down,
It is being connected to beam simultaneously laterally across connection reinforcing bar, and is passing through the seamless interfacing of rib and the company of spiral on beam between girder
Connect fixation, stability is high, and high-strength node dowel is also cross L-type strengthening steel slab, precast beam, prefabricated post, by structure that
It is fixed simultaneously between this, beam can also by mating connection reinforcing bar to further being reinforced between column, by overall stability into
One step improves, and adapts to fabricated development.
