Description
Technical field
The invention belongs to technical field of civil engineering, and in particular to a kind of part adhesive precast prestressed concrete frame knot
Structure.
Background technology
Precast prestressed frame structure is meant on the basis of Precast Concrete Frame, is applied to node and Vierendeel girder
Prestressing is formed by structural system.The frame structure system can realize large span, and speed of application it is fast, it is high-quality, can
It is a large amount of to save template and support.Be it is a kind of meet industrialized development need, can be achieved it is energy saving with structure-integrated structural system.
Existing precast prestressed frame structure system has generation structure system, PRESSS systems and subassemblage concrete frame
Frame structural body system.Generation structure system passes through cast-in-place coagulation by precast concrete column, pretensioned prestressing composite beam, precast slab
Soil is formed by connecting, and presstressed reinforcing steel does not pass through joint cores, is to form integrated prestress system in the system.PRESSS systems are adopted
It is attached with post-tensioning unbonded prestressing tendon and regular reinforcement, presstressed reinforcing steel is passed through and reserved in beam longitudinal central axis line position
Presstressed reinforcing steel duct links together the both sides crossbeam of column, and beam column seam fills mortar.Regular reinforcement indulges muscle up and down by beam
The reserved duct in position passes through pillar, and is in the milk in scene.The system presstressed reinforcing steel is in beam section intermediate arrangement, it is difficult to fully hair
Wave its contribution for structural bearing capacity.In addition, structure is continuous caused by unbonded prestressing tendon Yi Fashengyin anchorages destroy
Collapse.Subassemblage concrete frame structure system be by post-tensioning, multistage, the straight-line prestressed Tension Forming of soap-free emulsion polymeization it is pre-
Prestressed concrete frame processed.The system tensioning construction is complicated, and unbonded prestressing tendon Yi Fashengyin anchorages are broken
Approaches for Progressive Collapse of Structures caused by bad.
For current precast prestressed concrete frame structure there are the problem of, the present invention proposes a kind of precast prestressed
Frame system.The system pours monoblock type connection after using, precast concrete beam, column, board member are answered by cast-in-place concrete and in advance
Power formation is reliably connected.Muscle is indulged by welding or sleeve connection in the lower part of contiguous prefabricated beams of concrete, precast concrete beam it is upper
It indulges muscle and is set to overlapping layers and scene binding in portion.Precast concrete column is constructed using multilayer prefabricated post.Presstressed reinforcing steel uses post-tensioning
Construction technology, and pass through joint cores.Presstressed reinforcing steel uses carbon fibre reinforced plastic (CFRP) presstressed reinforcing steel, and according to design
Presstressed reinforcing steel is arranged as curved shape by internal force, to improve the application efficiency of presstressed reinforcing steel.Prestressing force is constructed using part adhesive, i.e.,
The plastic bushing that presstressed reinforcing steel is covered to embedded butter in the region close to node, waits for that tension of prestressed tendon completes post-grouting,
It can be formed adjacent to that node region is soap-free emulsion polymeization, other regions are to have cohesive part adhesive construction.The one of inventor's completion
Campaign has research shows that the advantages of this construction combines soap-free emulsion polymeization and bonds two kinds of adhesive forms entirely compared with high-mechanic
Power, while the ductility and deformability of structure are improved again.
Part adhesive precast prestressed concrete frame structure proposed by the present invention has good anti-seismic performance, meets me
The development strategy of state's green building and industrialized building has very wide application prospect.
Invention content
The purpose of the present invention is exploitation one kind both having met overall performance requirement, and anti-seismic performance is good, while meeting indoor big empty
Between demand, save material, construction easily part adhesive precast prestressed concrete frame structure.
A kind of precast prestressed concrete frame structure using part adhesive proposed by the present invention, the frame structure by
Several precast concrete columns 2 and several precast concrete beams 3 are composed, and further include that presstressed reinforcing steel 1, rear pouring concrete are folded

Concrete folding layer 5 is connected with rear pouring concrete joint cores 6；Precast concrete beam 3 is equipped with presstressed reinforcing steel 1, described
Presstressed reinforcing steel 1 is constructed using unbounded prestressed, and passes through rear pouring concrete joint cores 6；Presstressed reinforcing steel uses curved configuration,
To improve the application efficiency of presstressed reinforcing steel 1；Presstressed reinforcing steel 1 is constructed using part adhesive, i.e., close to rear pouring concrete node core
The plastic bushing that presstressed reinforcing steel 1 is put on to embedded butter in the region of heart district 6 waits for that post-grouting, i.e. shape are completed in 1 tensioning of presstressed reinforcing steel
It is soap-free emulsion polymeization in the region of Cheng Hou pouring concretes joint cores 6, other regions are to have cohesive part adhesive construction.
In the present invention, precast concrete column 2 is constructed using multicolumn, at the scene precast concrete adjacent during assembly
Column uses staggered floor arrangement, and the longitudinal reinforcement reserved when so as to realize that precast beam lifts in place well occurs with prefabricated post
The problem collided and can not be in place.
In the present invention, in the multicolumn construction, it is located at the bottom surface setting grouting air slot of the precast concrete column on upper layer,
And stayed at center and set gas vent 8, when to pour rear pouring concrete overlapping layers 5, it is located at the precast concrete column bottom on upper layer
Air is discharged by the pvc pipe being embedded in the precast concrete column, and grouting air guide slot cross-section is triangle, and bottom edge length is
15mm ~ 25mm, a height of 10mm ~ 15mm, a diameter of 10mm ~ 15mm of gas vent.
The beneficial effects of the present invention are：
1, precast prestressed concrete frame proposed by the present invention has speed of application fast, and environmental pollution is small, saves the duration
And the advantages that template, meet the demand of housing industrialization.
2, experimental study shows that precast prestressed concrete frame proposed by the present invention has good globality and resists
Shock stability.
3, in of the invention, presstressed reinforcing steel uses part adhesive, can be in conjunction with soap-free emulsion polymeization and complete two kinds of adhesive forms of bonding
Advantage has compared with high-bearing capacity, while improving the ductility and deformability of structure again.
4, in the present invention, prefabricated post is constructed using multicolumn, and uses two layers of prefabrication solutions.At the scene during assembly,
Adjacent multicolumn uses staggered floor arrangement, when so as to realize that precast beam lifting is in place well it is reserved lift one's head reinforcing bar with it is pre-
Column processed collide and can not be in place problem.
5, in the present invention, grouting air slot is set in upper layer precast concrete column bottom surface, and stayed at center and set gas vent.
In sleeve filling process, air enters pre-buried pvc pipe by central exhaust port, column is finally discharged through air slot in seat pulp layer
Outside.Experimental study shows that setting grouting air slot can effectively dredge gas, ensures seat pulp layer grouting compaction rate.
